PREFACE.

When, in January, 1886, the Division (.f Fossil Insects of tlie V. S.
Gooloo-iciil Sni'vey was established, and I entered upon my duties therein,
I had still in liiind in an iuooniplete condition a report upon our Tertinry
insects for tin- T. S. Geolo<)-ical Survey of the Territories, under 1 )r. F. V.
Hayden, the i)lates for which were already finished. Tliis work, which
was completed early in 1890, contained a ftdl account of all the Tertiary
insects (tf our country known up to within a few years, as far as re"-arded
the lower orders; but the hi<,dier orders, and especially the Coleoptera,
Diptera, and Hymeuoptera, which comprised those richest in material, were
left nearly untouched, only the earliei- found specimens in the Green river
beds, and which had already been engraved on the plates, being- included,
lea^^ng the far richer fauna of Florissant, Colorado, entirely untouched.

The elaboration of this immense amount of material, enlarged by
additions from other localities, including some new and i-ich, was begun
immediately upon the completion of the Hayden reixirt, and the ja-esent
work is a iir.st instalment toward a hi.story of our tassil Coleoptera. In
the diAasion treated are included 193 species, all Imt one of which come from
the older Tertiaries, while there have been described (or merely indicated)
from the European Tertiary rocks onl}- loO species, of which !» come from
the Pleistocene. Our older Tertiary rocks, therefore, are found to have
already yielded nearly 28 per cent more forms than the corresiionding
European beds. It is altogether probable, such is the extent and richness
of the fresh-water Tertiary deposits of the West, that this ijrojjortion will
be largely increased in the future, particidarly as the exploitation of our
Tertiary insect deposits has been merely begun; the number of persons
who have been engaged in any field-work upon them ma\- lie counted
up<pn oiu-'s fingers, and no natimilist besides myself has yet undertaken
their study.

TERTIARY RTTYNCllOPIIOROLTS COLEOPTERA
OE THE UiNlTEl) STATES.

By Samuel H. Scuddek.

INTRODlJin ION.

Althoiijjh it is evident to any student <»f" fossil insects tliat even in
Ti'i'tiary de})()sits we possess but a mere fragment of" tlic vast Iiost wliicli
nuist liave been entombed in tlie rocks, it is nevcrtliclcss true tiiat we iiave
already discovered such a variety and al)iuiilance of forms as to make it
clear that there has been but little important change in rhe insect fauna
of the world since the beginning of the Ti'rtiary ejxxli. In the earlier
Tertiaries we not only possess in profusion i-ejjresentatives of every on<^ of
tile orilers of insects, but every dominating family ty])e which exists to-day
has been recognized in the rocks; even many of tin- families whidi have
now but a meager representation have also l)eeii diseovered, ainl tliough
manv extinct genera have been recognized, no higher groups, witli a single
exception or two, have been founded ujjon extinct forms. This is one of
the most striking and prominent facts which confront tlie student of fossil
insects. It is the more striking froui the delicacy, the tenuity, and the
minuteness of many of the forms which have been entond^ed; and the state-
ment ina\ 111' enforced bv the further fact that the parasitic groups — those
which are entoiiiophagous — are represente(l, as well as many of those wdiicii
in tti«! piesi'iit time show peculiar modes of life. Thus we have rejiresenta-
tives of sucli microscopic parasitic in.sects as Myrmar, strepsipterous in.sects
have been discovered, the viviparity of the ancient Aphida- has been shown
probable, the s|)ecial sexmd forms of ants and white ants were as clearly

marked as to-day, and the triuiig'ulin larva of Meloe has lieen found in-
chised in amber, showinji' that the ))henonienon of hypermetamorphisni had
ah'cady been developed.

The hisects of the Tertiary period, therefore, afford no such interestincr
series as may be found in the study of Tertiary mammalia, nor as eau he
found in the study of the insects themselves in Paleozoic rocks. Never-
theless, a few interesting features have been pointed out which seem to
stand, in some measure, as exceptions to what has been stated. Thus, in
my recent work on our Tertiary insects,^ I called attention to some remarka-
l)le features in the fossil ])lant-lice of our Tertiaries, especially the great
lensrth and slenderness of the stigmatic cell — a feature which affects the
whole to])ograpll^' of the wing, and is found also in the only 3Iesozoic plant-
louse known, Ijut which, nevertheless, can not be regarded as of significant
taxonomic importance, since it occurs equally in both the A[)hidin;v and
Schizoneurina', the two principal subfamilies of that group, l)oth to-day and
formerly. 80, too, in treating in the same place of the Pentatomida?, I
pointed out tliat the scutellum was universally shorter in all our Tertiary
forms, whether belonghig to the sul)family of Cydnin;e or Pentatomina'. T
may further add the uniniblished fact that it is a peculiarity of the Tertiary
Staphylinida- of this country that the antenna- ;uid legs are measurably
shorter than in modern types; this is most marked in cases where the living
and extinct species of the same genera are compared. But in neither of
these cases, any more than in the Aphidae, can we regard these peculiari-
ties as any ground for separating the fossil from the recent forms as distinct
groups. No doubt we shall some day be ai)le to correlate these differences
and point out their precise significance, which at present is not clear, but it
is certain that they do not afford ground for maintaining that we are here
dealing with extinct groups any higher than genera, or, at most, than tribes.

Yet in one or two instances extinct groups of a higher grade may
be found. Thus, in the work already alluded to, and previously, I have
drawn attention to a strange ty])e of fossil Thysanura — Planocephalus —
for which it seemed necessary to frame a new suborder, and, though its

possible referenre elsewhere has been su<;<,r('stetl, tliis stiororfstioii will Imrrlly
stand the test of investig'atioii, ami the matter remains wlicn- I left it; and
in the present work attention is directed to another yroup — the ( 'oleopterons
tamih K'ln ncliitida — in wliicli it has been fonml niMi-ssary to establish a
new siibtaniilv ^roiip tor an abundiinl and varied scries ot" insects trom our
Tertiaries.

In stndyino- the Hliyn(lioj)horons ( 'oleoptera, 1 have, for the first time,
made use of all the material which has l)ecn collecte<l in the most recent
as well as in former yenrs; and have been able, therefore, to do justice to
the other localities of fossil insects, as well as the now fanions locality of
Florissant, Colorado, ami 1 tind tliat there is no family oi' American Rhyn-
cliophora paleontologically more interesting than the Rhynchitida?. In point
ot' numbers alone the species of this group form more than 10 per cent of
tlie fossil Hhynchophora of North America, while in the existing fauna the
Hhvnchitidpp comprise less than 2i per cent of all the Rhyn«'liophora. Our
recent Rhynchitida- are separated by IjC Conte and Horninto two subfamilies,
one of which comprises the bulk of the family, wdiile a single species is sepa-
rated to form the other, the Pterocolinaj. This differs from the Rhyiichitina%
among other things, by the antennae being inserted much nearer the eyes,
by the wide separati<in of the fore and middle coxae, and by the broad side
pieces of the raetasternum. The PterocoliniB are not represented among
the fossils, but all the genera of Rhynchitina^ now existing in our fauna are
recognized, as well as a new generic type. These, however, are but a
mere fraction of the fossil Rhynchitida% the l)ulk of them being separated
as a new sidifamily — the Isotheina', a subfamily characterized by the mod-
erate separation of the fore and middle coxaj, and by the insertion of the
antennif, which is before the middle of the basal half of the straight and
pon-ect beak. These characters show an approach to the I'terocolinai rather
than to tlie Rhyn(;hitina', but they have narrow metastenial side pieces. This
subfamily, thus clearly distinguished, is, for Rhynchitidsr, exceptioTially rich
in forms, since it contains no less than seven genera and thirteen species,
about equally diAnded between two distinct tribes, all extinct. This brings
the total number of fossil American Rhynchitida; up to four-fifths that of

TEltTJ AK Y KH YNCHOPHOROUS COLE( )PTER A.

the existing forms, a proportion wliich altogether surpasses that yet found
in any other family of insects. The abundance and variety of the Rhynchi-
tida3 may, therefore, be looked upon as the most striking feature in the Ter-
tiary Rhynchophorous fauna of North America.

Tlie relative representation of the diifereiit fannlies of Rhynchophora
ill the Aiiicricaii and European Tertiaries, as Avell as their representation in
America to-day (according to Henshaw's catalogue of 18S6), is set forth
succinctly in the following table:

This table shows lietter than any words, some striking features in
the American Tertiary fauna, when compared with that now existing in
North America, and, indeed, to a certain extent and in much the same
direction when compared witli tlie European Tertiary fauna. These
peculiarities consist in the extraordinary development of the Rhynchitidpe,
already alluded to; the great preponderance of the Otiorhynchida?, due to
its remarkable development in localities other than Florissant, and the
meager showing of the Scolytid;v, this last also seen in the European Ter-
tiaries, and undoubtedly resulting from the habits of life of these insects
as subcortical feeders on trees, which woidd prevent their deposition in
places where their fossil remains could be preserved. The reduction in
this direction is, indeed, so great as to etfect a very slight lessening of tlie

relative numbers of the Ourouliunid.T, which iierc, as in tlie living' fauna,
easily hold tlie fu-st ])lace. The other relative dilVercinees between the Ter-
tiary and existing- faunai^ in Anieriea are l)ut slight, the ('alandrida- of the
Tertiaries losing al)out as much as the Anthribi<l;e gain in relative numbers
when compared with the existing fauna. As compared w itii tin- Kuropean
Tertiary fauna the American shows the same excess in the relative num-
bers of Rhynchitida' and Otiorhynchida- as it does when compared with the
recent American fauna; but both the Curculionida' and tlu^ Scolytida' gain
in rehxtive importance in .tlie Euro})ean Tertiaries, whose chief peculiarity,
however, consists in the considera])le development of the small family
Byrsopida. The Rhinomacerida' an<l IJrenthida' alone, small groups, do not
occur in either Tertiary fauna, and the Attelabida' and liyrsopida- are also
absent from the American.

To brinjr the differences to view in another wav and consider oidv the
families represented in the American Teitiary fauna, we ma} mark their
relative position in the scale of numl)ers as in the following- table:

This shows by a different method the same fact: That the recent
American Rhynchophorous fauna agrees l>etter in its broad features witli
the Tertiarv fauna of Europe than with the Tertiary fauna of America.

Of the G(i ol<l genera to which the fossil species of Rhynchophora are
here referred, including 13G of the 11)3 specie.s, G may be regarded as cos-
mopolitan or nearly so; lo as gerontogeic and especially European, though

divided between those wliicli are predominantly North American and those
which are tropical American, but often extend to our soutliern l)orders. Of
the 31 new g-enera (with 57 species) little can be said in this })articular, but
nearly half of tlu^m may be i-eg-arded as most closely allied to American and
especially tropical American types; so that on the whole the American, and
especialh' the tro])ical American, ty{)e jjredominates. It should be remarked,
however, that the n-scinldaiicc of the fauna to that of temperate North
America is uiidoiibtedh' greater in ap})earance than in reality and will ver}"
probably be changed to some extent when the various species here recorded
are better known; for, in default of characters which if preserved might
materially change tlie alleged atHnities of the various forms, it has seemed
advisable to refer most of them to existing genera, and my opportunities for
examining tro|)ical ami suljtropical ty])es have been very limited. Where
characters of real importance exist, the insects generally show the preva-
lence of structural differences, often considerable, from modern forms.

The number of new genera here propos(ul is certainly greater than has
been usual in the study of Tertiary insects, but this I believe to be a neces-
sity if we are to tipidy the same methods to their studv that we do to the
study of modern insects; nor is the number surprising, since not a single
species is found in oin- T(-rtiary deposits which can possibl}' be referred to
an existiuii' form or even to any of those which have been described from
the European Tertiary rocks; and 1 am convinced that the actual difference
between the older Tertiary and existing types is far better expressed by the
separation of the former from the latter in generic nomenclature whenever,
the characteristics l»eing .sufficiently preserved, they show any such differ-
ences as among modern tvpes are regarded as warranting" generic separation.
It must be confessed, however, that among the fos.sils the (^oleoptera are
far less apt to lia.ve those characteristics of tiieir structure wliich are seized
upon for generic disassociation sufficiently jjrtserved to warrant great cer-
taint\' or insure exactitude and that those orders whicli disjjlay wing neu-
ration afford far better means of judgment, on account of the commonly
better preserved remains of just those parts which are largel}' relied upon
for generic disci'imination.

beds of Scarboro, ( )ntario. These four locaHties are Florissant in central
Colorado, the crest of the Roan nioiiiitains near the head of East Salt creek
in western Colorado, the huttes bordering the AVhite ri\cr near the Colorado-
Utah l)iiundai-v, and (ireen river city, Wyoming. All of these localities,
except the Roan mountains, were described in more or less* detail in my
Tertiary Insects of North America. The Roan mountain beds are appar-
ently merely an extension of those found on the White river, 50 miles dis.
tant, but here contined to the very crest of the range. Fossil insects are
found at several points, but only in one spot have they been obtained in
any remarkable number; here, however, in extreme abinidanee. As this
spot was T) miles di.stant from our camp and (lui-tiiiie and supplies were lim-
ited, no great number of specimens were brought away, but enough was
seen to warrant; the belief that a prodigious nundjer of specimens might be
obtained there.

The detailed study of the fossil Rhvncdiophora has made very clear and
specific one point which im])ressed me in general while working in the
tield, and that is the wide diHerence between ihe character of the fossils
obtained at Florissant and those obtained at anv of the other localities
(perhaps excepting Flko, Nevada, of which little is known) in tiie Rockv
mountain region. The Hymenoptera which al)ound at Florissant almost
disa()i)ear in the other localities, while the Coleoptera, which hold a third
place at Florissant, form the larger proportion of the mass in the other
deposits. To test the opinion formed l)y the cursory examination of speci-
mens in the field, I have counted the specimens obtained in each of the
ditl'erent localities visited during a single sunmier, and find the opinion
amplv confirmed.

The first .set of columns in the accompanying table shows the total
number of specimens (regardle.ss of s])ecie.s) obtained during this season's
work, separated by onlers, (!) in all localities; (2) at Flori.ssant alone; and
(3) in the other localities, ex(duding Flori.ssant; and the second set of
colunms the same figures reiluced to percentages. Nothing couM well be
more striking than the contrasts in the 1 1 xinenoptera and Coleoptera.

Now, when we come to examine the species of Rhynchophora, we
shall find that while the three localities in western Colorado and Wyoming
share a nninher of forms in commim, lutt a .sing-le species fonnd at Floris-
sant occnrs in either of the others. To give the precise figures : From
Florissant 116 species have been obtained; from the Roan nKnintains 40,
of which it shares f> with GreiMi river and 7 with White river, besides 6
others common to all three localities, together nearly half its fauna (19 sp.);
from the White river 23 species, of which it shares 2 with Green river and
7 with the Roan mountains, btisides the G common to all, or nearly two-
thirds its fauna (IT) sj).); and from Green river 3D species, of which it
shares 2 with White river and (! with the Roan mountains, besides the 6
common to all, or more than one-third its fauna (14 sp.). These facts, with
the held evidence, a,])pear to show tjiat the three principal lo(%alities in west-
ern (Joloratlo and Wyoming arc deposits in a single body of water, the an-
cient Gosiute lake, as it was called by King. The absolute separation,
in speciific forms, ])etween the fauna of these deposits and that of Florissant
must be indicative of a distinction greater than that of mere geographical
position, for the Roan mountains are about equally distant from Green
river and Florissant. It is clearly an indication of a difference in age,
thougli they have usually been reganled as occupying similar horizons. In
the following jjages I have referred to the species regarded as belonging to
the Gosiute lake as the Gosiutk fauna whenever it has been desirable to
speak of them in conimon; and in contrast I have called the fauna of Flo-

INTHODIcnoN-. 9

rissuiit, the Florissant or I^.vcu.strim: kaina. Which of them is the older can
not be (let»'riuiii(<l until their faiiiias have been more completely stndied;
and even then, tor lack of siitlicient comparisons elsewhere on the conti-
nent, it may be impossiljle from the insect remains alone to reach any pos-
itive conclusions. When the structure of the Green river beds has l>een
more completely studied, their age can doubtless be determined with much
accurac); and a similar result may be reached when the age of the oro-
graphic movement shall have been determined which brought about the
emptj'ing and desiccation of the ancient Florissant lake. With these time
elements given, the extent of the insect remains in the Gosiute and Lacus-
trine faunas is such that the relations of deposits hereafter discovered may
quickly be made clear.

The difference between the Gosiute and Lacustrine faunas is shown
to be much more remarkable when we examine the larger groups. Thus,
of the 66 genera found at Florissant, only 18 occin- also in the Gosiute
fauna, which contains, besides, 81 genera not found at Florissant, and there
are even a number of tribes which, as far as we yet know, are entirely
confined to one or the other fauna.

Besides the beetles described or enumerated in this work, no fossil
Rhynchophora have been described from any formation. Tertiary or pre-
Tertiary, on the American Continent, with the single exce})tion of a species
of CurcuHonidtv which I have caWiid Ilyl oh iites cretacens^ and which was dis-
covered in the Pierre shales of the Assiniboine river, northwestern Manitoba,
by Mr. J. B. Tyrrell, of the Canadian Geological Survey, in 1888.

In conclusion, the following statejnents inav be made regarding the
Rhynchophorous fauna of the American Tertiaries in general :

(1) The general lacies of the fauna is American, and somewhat more
southern than its geograjjhical position wovdd indicate.

(2) All the species are extinct, and though the Gosiute lake and the
ancient lacustrine basin of Florissant were but little removed from each
other, and the deposits of both are j)resumably of Uligocene age, not a single
instance is known of the occuirence of the same .species in the two basins.

(3) No species are identical with anv European Tertiary fonns.

'Cont. Can. raliimt., ii. :fll-:{l, jil. Ii. lig. ;'..

10 TERTIARY RIIYNCIIOPHOROUS COLEOPTERA.

(4) A very considcralile imiiil)er of genei'a are extinct, often including
a niiinl)er of species.

(5) Existing genera \\liicli are repi'esented in the American Terti'aries
are mostly American, not infrequently subtropical or tropical American,
and where found also in tlie Old World are mostly those which are common
to tl le North Temperate zone. A warmer climate than at present is indicated.

((;) There are no extinct families, but in one instance an extinct siib-
family with numerous representatives.

(7) The Tertiary European fauna is nearer than our own Tertiary
fauna to the existing American fauna in the relative i^reponderauce of its
families, subfamilies, and tribes.

These conclusions are almost identical, word for word,' with those
reached from a study of the Tertiary Hemiptera of the United States,
although in that study a far more meager representation of the Gosiute
fauna was at hand.

Besides a mniiher of specimens which could not be definitely placed,
thei'e have been examined in tlit- preparation of this monograph 753 speci-
mens of Rhynchophoi-a, of whicli 431 come from Florissant and 320 from
the Gosiute fauna.

Three of the plates which accompany this monograph were put upon
stone man}' years ago and before a careful study of the material. Conse-
quently several species appeal- on them which are not Rhynchophora at all.
Thfese have all been described, and the descriptions will in due titue and
place be published, l)ut in tliis volume only the names are given, in the
Explanation of Plates i and ii.

In the enumeration of the specimens at the end of the specific descrip-
tions, tlie numl)ei's of tlie obverse and reverse of the same specimen are
always connected I)}- "and" witliout any intervening comma, and this typo-
graphical method is enqdoyed only in exjiressing this relation.

My warm thanks are due to Mr. Samuel Ilenshaw, of Cambridge, for
liberal aid witli liis nillcction and by his personal knowledge of living forms,
botli of whicli have l)een oi' the greatest service to me.

DESCRIITIONS OF SPECIES.

Family RHYNCHITID^E.

There is no fiiiiiily of Ainoricaii Rhvnfho])hor;i jjaleontolog-ically more
interesting' tiian the Kliynchitida'. In point ot" numbers the species of this
oniup form 10^ per cent of the fossil Rhynchophora of North America,
while the recent species comprise less than 2^ per cent of the existing fauna.
They were also vastly more numerous, both absolutely and relatively, than
in Kurope, where they compose only about 33 per cent of the Tertiary
Rhynchophora.

In keeping with tliis fnct of tlicir nmnerical importance is that of their
variety of type. (Jur existing native species have been grouped in two sub-
families, one composed of three genera, the other of one. All these genera,
excepting Pterocolus, the type of the Pterocolina;, are recognized among
our fossils, l)ut they include a mere fraction of the fossils, which embrace,
besides a new generic furiii of Rhynchitina', an entirely new subfauiily of
Rhyncliitidty with two tribes, seven genera, and thirteen species, about
equally divided between the two tribes. The total number of fossil species in
America is therefore fully two-thirds that of the existing forms, a proportion
which altogether surpasses that found in any other fainily of insects. Nor
is there any other family of fossil insects where it has been found necessary
to establish a distinct subfamily grou]) for an entire series of new forms.
The abundance and variet}' of Rhynchitida' may therefore be looked ujion
as the most striking feature in the Tertiary Rhj'nchophorous fauna of North
America. Of the twenty species found in our Tertiaries, three quarters are
found exclusively at Florissant.

Subfamily RHYNCHITINyE.

Each of the three genera of Rhynchitina- now found in North America

these, an extinct genus, Masteutes, has two representatives at Florissant.
The actual number of species is therefore a little greater than in the
European Tertiaries where four species have been referred to Rhynchites
(some of which, as will be -pointed out later, will probably l)e foinul to be-
long rather to the Isotheinae) and one to an extinct type, Antliarhinites.

MASTEUTES {txaarevTr^^), gen. nov.

This genus is founded principally upon the first of the two species here
described, the other being insufficiently preserved to be sure of its position.
The head is liere of small size, conical, with circular or transverse eyes, the
antenn* attached to the middle of the rostrum, about as long as the pro-
thorax, and consisting of similar, equal, slender joints perhaps twice as long
as broad, excepting the last three, which form an elongate oval club fully
twice as broad as the preceding and itself more than twice as long as broad.
The prothorax is large, tumid, well roinided, and scarcely narrower than
the base ()f the elytra. These have longitudinal markings and apparently
cover the pygidium.

Two species occur, both at Florissant.

PI. Ill, Fig. 29.

The dorsal view is seen in the only specimen we have. The head and
rostrum, the latter hardly longer than the head, are very delicately granu-
late. The prothorax is coarsely and densely granulate, as are also the fore
femora; the prothoi'ax is tumid, largest in the middle and with convex sides,
the base a little narrower than the elytra. The position of the fore coxae
can be seen through the body, showing them to be separated by about one-
third or one-fourth of the diameter of one of the coxal cavities. Elytra with
nine visible series of sharp granulate carinaj, the granulations indistinct,
but of the same size as those on the prothorax, though elongate; there are
also marks of the interspaces having been clothed sparsely with short hairs.

This species is placed here with hesitancy on account of tlie great lenf;;th
of the snout, but its general resemblance to the other species seems other-
wise considerable. The head is very delicately and faintly granulate, as is
also the rostrum, which is very gently arcuate, and slightly longer than the
protliorax. The head, however, shows somewhat of a transverse aiTange-
ment of the granulations, giving a subcorrugate appearance. The protho-
rax has a similarly delicate, circular, but more distinct and densely crowded
granulation. The sculpture of the elytra is vaguely preserved, but appears
to be nuich as in the preceding species.

is otherwise known j)rincipally from southern Europe and the Mediterra-

small size, closely allied to Rhynchites. They have not before been recog-
nized in a fossil state, and but a single specimen has been found at Floris-
sant, Colorado.

EUGNAMPTUS Schonherr.

Excepting a single Indian s])ecies of pecidiar appearance, all the mem-
bers of this slender type of Rhvnchitida^ come from North America, where
we have 5 species, mostly occurring in the southern and western states.
They have been found fossil only in this country, at Green River, Wyo-
ming, where we have two species (neither of them refeiTed here with any
great confidence).

RHYNCHITES Herbst.

A numerous o-roup of nearly cosmopolitan distribution, though mui li
richer in the northern than in the southern hemisphere. We have more
than a dozen species in the United States, occurrinjr mostly in the West, but
it is far more abundant in the Old World. Four fossil species have been
described from the Eluropeaii Tertiaries, two eacli from Kott and Oeningen,
and a single species i.s described beloAv from Florissant. The last does not
agree well Avith any of the Kuro])ean fos.sils, but is ])erhaj)s nearest to //.

The head is smooth, e.xcept for a slight transverse wrinkling, and,

The species does not appear to agree well with any of the described
fossil species of Rhynchites most of which, indeed, as already stated, must
be removed from the genus; and from our modern species it appears to
differ in its relatively much broader thorax.

Subfamily ISOTHE1N.C

The genera belonging here, and especially those of the first tribe,
have all the aspect of Calandrida^, with their elongate form, porrect ros-
trum, and subconical head; but the relatively great head, ungeniculated
antennae, the loose club of the same, the four-jointed tarsi, and the subequal,
completely delimited segments of the abdomen prevent the possibility of
any such reference.

They are peculiar among Rhynchitidw for the moderate separation of
the fore and middle coxa? and the insertion of the antenna?, which is before
the middle of the basal half of the straight and porrect l^eak. These char-
acters show an approach to the Pterocolinfe rather than to the Rhynchitida?,
but they have narrow metasternal side pieces. It seems fitting, therefore,
that they should be separated as a distinct subfamily.

To judge only from the descriptions and figures of the species of fossil
Rhynchitidfe already described it is highly probable that several of them
also may fall in this same subfamily, for the two species of Rhynchites
described from Rott by Heyden, B. liageni and R. orcinus, have the anten-
na attached at the very base of the rostrum, showing, at least, that they
can not properly be placed in Rhynchites, and the same is the case with the

UHYNCIIITIIKE — ISUTUEIN.E — IScmiEINl. 1 7

remarkable form found at Oeningon, for which Heer lia.s proposed the name
Antliarliiims, on account of the rostrum "of a hair-like fineness."

The occurrence of other Khynchophora, which iiuist phiinly Ijclon','' to
the Rhyndiitida', liut which share with Pterocolus some characteristics other-
wise peculiar to it, is distinct evidence that Le Oonte was correct in sepa-
ratinjT Pterocohis from the genera with which it had been formerly asso-
ciated and placing it in the Rhynchitida'.

There appear to be two groups of genera belonging to this subfamily,
which provisionally may be regarded as tribes. They may be separated as
f(jllows :

Table of the tribes of Isotheina:

Largp species normally of an elongated form with straight dorsum, the heatl generally
of considerable length and the rostrnni always rigidly straiglit hotheiiii.

Small species normally of a plump and compact form, with well rounded dorsum, the
head shorter. the rostrum either straight or gently eiuved Toxorhijnvltini.

Tribe ISOTHEINI.

The memliers of this tribe are peculiar for their considerable size, the
elongate, more or less parallel-sided form, there being scarcely any if any
diminution in breadth forward before the middle of the prothorax; some-
times, however, they are stout, but then do not have so arched a Itodv as
in the sue -einling tril)e: the head is usuallv of exceptional length, and th(!

PALTORHYNGHUS {naXrhv, pvyxo?) gen. nov.

Closely allied to Isothea, described below, differing" from it in the gen-
eral form of the body and tlie structure of the antemife. The form is dis-
tinctly parallel-sided througliout nearly the whole of its extent, l)eing
broadest at the middle of the prothorax. The rostrum is slender and
twice as long as the rest of the head, straight and porrect, and yet to-
gether with the head not much, if any, over half as long as the rest of the
body. Antenn.'B of the same length as in Isothea, the first and second joints
subequal, scarcely if at all stouter, and certainly shorter than joints 3-H,
which are subequal, two or three times longer than broad, 9-11 forming
an elongate ovate club not very deeply annulate, its basal joints at least
only a little broader at apex than at base. Eyes moderately large, lateral,
not prominent. Legs rather short and not stout. Third ventral segment
of abdomen as long as the second.

Dr. J. L. Le Conte, who, many years ago, cur.sorily examined one of
the specimens of this genus, remarked to me that it was a "verj' strange"
insect.

Three species occur in Colorado, one of them not uncommonly.

The imperfection of the specimens does not permit certainty in generic
location of this species, and it is placed here only becau.se of the general re-
semblance of the surface sculpture of the elvtra, which is somewhat remark-
able. One of the .specimens shows onl\ the fragment of an elytron, the
otlu'r the dorsal view of the protjiora.x and elytra. Phe |irothorax, not per-
fect, is taintlv, distantly, and coarsely punctate, and shows a pair of longi-
tudinal stria' close beside the niiddle lin«. The elytra are together about

ISOTHEA (eiGGoOdco), gen. nov.

The head in this genus is of exceptional length, being slightly longer
than the rostrum, and with it two-thirds as long as the rest of the body; it
tapers regularly, but with full sides, to the rostrum which is stout, fully one-
fourth the breadth of the head. Antennaj almost as long as the greatest
width of the body, fully a third longer than the beak, joints 1-2 subequal,
slightly shorter and a little stouter than thoSe succeeding, 3-5 longest, 6-8
about half as long as 1-2, 9-11 large and broad, forming an open clul), of
which 9-10 are twice as broad at apex as at base, subtriangular and trun-
cate, the terminal joint obovate. Eyes large, lateral, not very prominent.
Legs somewhat shorter than in Rhynchites, but with identical form, includ-
ing the tarsal joints, unless the penvdtimate joint is more deeply bilobate.
Structure of elytra indeterminable. T'hird ventral segment of abdomen dis-
tinctly shorter than the second.

The form of the body in this genus is somewhat elongate but not par-
allel-sided, showing a somewliat oval outline and being broadest in the
middle of the abdomen.

A single species occurs at Florissant.

On account of its small size, the punctate head free from transverse

position and not perfectly clear preservation, 1 have Iiad some douljt about
placing this insect here, but the position of the rostrum seems to l)e due
to the excessive bendhig of the head, as shown h\- the longitudinal wrinkles

for refusing it a place here.

A genus of Rhynchitidae comprisiug beetles of smaller size and plumper
form than the others in the subfamily of Isotheinte, in which, on account of
its general resemblance to them and the character and insertion of the an-
tennae, it appears to fall. Of the separation of the coxse nothing can be
said. The head is not more than half as long as the prothorax, well rounded
from base to beak, the latter long, rigidly straight, equal, and slender, with
the head at least as long as the elytra. The eyes are obscurely preserved,
but apparently small, circular, and situated next the base of the beak. The
antennae are slightly longer than the prothorax, seated slightly within the
middle of the basal half, the first two joints a little stouter than the follow-
ing, equal, si;bovate, hardly twice as long as broad, the succeeding up to
the club slender, cylindrical, equal or subequal, more than twice as long as
broad, and scarcely longer than the basal, the last three twice as broad,
scarcely longer than broad, subquadrate, forming a loose subcylindrical
club. The prothoi-ax is higher than long, even ; the elytra well arched, the
sculpture longitudinally disposed; the legs slender and not very long. The
metasternum is long, the pygidium apparently exposed.

The eyes are small, transversely oval. The beak is separated from the
head by a distinct though fine constriction, is slender, scarcely arcuate, por-
rect, fully as long as the prothorax. The antennae are not preserved. The
prothorax is tumid, considerably higher than long, roughly sculptured.
The elytra are also rather coarsely sculptured, but are scarcely at all arched.

Family OTIORHYNCHID^E.

Tlie Otiorhynchidiv are well represented in the American Tertiaries,
tile nuiiK ri<;il })reponderance of the species having then been much more
than double what it is now. But the most striking fact is its importance
for the Grosiute fauna, where 15 genera and 32 species occur, against 10
genera and 14 sjiecies at Florissant. Excepting in the Scolytida?, which
liave hut 4 sj)ecies in the western Tertiaries, and are thus relativel}' insig-
nificant, no other family shows a preponderance of forms in tlie Gosiute
fauna; and as the pre[)onderance is here very marked we may i'airh- regard
the ( )ti(prhvnchida; as thoroujjhlv characteristic of this fauna. It is a fur-
ther curious fact that the Florissant Otiorhynchidaj are mostly made up of
members of different tribes from the others, the Evotini an<l I'romecopini
belonging e.xclusively, or almost exclusively, to the Lacustrine fauna, while
the Tanvmecini, Uyphini, and Phyllohiini are exclusively, the more nu-
merous Ophrvastini and ( Hiorhvnchiiii almost exclu.sively, Go.sinte; the
Brachvderini alone are divided equally between ])oth. No other family of
l{hvnchoi)hora .shows in so striking a manner a division of tribes between
the two principal liori/.oiis of the western Tertiarv insect beds, and it is
therefore prot)able that the fossils of this famil\ ma\ in the future turnish
the best indications (as far as Khynchophora are concerned) of the horizon
of future insect localities in the West.

In Europe the number of genera and species is far less than in
America, and the tribes Ophryastini. Evotini and I'romecopini, having hi
America fully two-fifths the genera and nearlv half the spe<'ies, do not
appear to occiu" at all, nor do any tribes occur in Eurojie which are nfit
found in .\merica, excepting the extinct tribe Pristorhvnchini, which is rej)-
resented by a single species. Even in the tril;es that are the same the

genera are mostly different; thus the Brachyderini are represented by
Liparus, Auisorhyuchus, and Brachyderes, iive species in all; the Otiorhyn-
chida? by Otiorhynclms and Laparocerus, a half dozen species, all Pleistocene;
the Tanyinecini by Thylacites, a single species; the Cyphini by Naupactus
and Strophosomus, a couple ot" species; and the Phyllobiini by Phyllobius
and Polydrosus, in amber. We find, therefore, only 11 genera and 17
species in Euro})e, against 23 genera and 47 species in America. The
importance of the Otiorhynchidre in the American Tertiaries, and particularly
in the Gosinte fauna, is therefore appai-ent

The following table will give in detail the jieculiarities of this distribu-
tion, by which it appears that the rehxtive development of the different
tribes in the recent American fauna is in this instance more nearly
approached l^y the American than by the Em'opean Tertiary fauna.

A half dozen fossil species of this tribe have been found in America,
three species of Epicferus, typical of the Grosiute fauna, and one species
each of Hormorus, Trigonoscuta, and Teiiillus, tlie last an extinct type, all
from the Florissant basin, and so far as known peculiar to the Lacustrine
fauna. In the European Tertiaries it was one of the most abundant tribes

of Anisorhynchus liave been described and figured from Kutschlin ;iiid
Corent by Deichmiiller and Oustal(^t, and two of Hracliyderes from Aix l)v

EPICURUS Laporte.

This is an exclusively American type of weevil, far more abundant in
tropical and subtropical than in temperate America, l)ut three or four species
occur in our southern states, including one as far north as Pennsylvania.
Three species, possibly to be referred to two, are found in the western
Tertiaries, though none of them are found at Florissant. It seems to be
the prevailing type at Green river, White river, and the Roan mountains,
and may be regarded as one of the characteristic featm-es of the Gosiute
fauna.

HOKMORUS Honi.

A genus founded on a single species from eastern North America, still

HORMORtJS SAXORUM.

PI. II, Fig. 4.

Pro\'isionally, until further material is ol)tained, I place in this genus a
species which seems to belong here or in its near neighborhood from the
structure and relations of the posterior coxai, the straight suture between
the first and second abdominal segment, the length of the antennal scape,
the form of the rostrum, and the general facies; but the length and slender-
ness of the funicle of the antennae, and indeed of the scape as well, indicate
that it should be placed outside of it but in the near vicinity; the third
and fourth abdominal segments also are together somewhat longer than the
second. The single specimen is, unfortunately, not very well preserved,
but shows the tollowing characteristics: Head smooth, with delicate, trans-
verse, curving rugae; rostrum (incoiTectly rendered on the plate) straight,
declivent, nearly as long as the thorax, stout, being fully half as high as
long, equal or suljequal, finely graiudated, the apex rounded; ej'es rather
^small, rounded, not over a third as broad as the rostrum. Antennjv very
slender throughout, the scajie enlarged apically but not coanselv, attaining
the middle of the eye; funicle exceedingly slender and equal, nearly as
long as the head and rostrum together, the club lacking. Prothora.v sul)-
cylindrical, equal, without tubero.sities, minutely nigulosc. Klvtra poorlv
preserved, but with series of indistinct cu'cular leuticlos, probably casts

TRIGONOSCUTA Motschulsky.

A genus known by a single species only, from California. The fossil
species which I place here can hardly have found its proper home, though it
would seem to be not far removed from it. Tlie stoutness of the rostrum
and want of oblicpiity of the antenna! scrobes, with its more compact form
and the greater trausverseness of the thorax, would seem to separate it,
while the form of the femora, the relation of the coxje, the breadth and
convexity of the intercoxal process of the hind legs, the form and size of the
second abdominal segment, and the course of the suture separating this from
the first segment are points of particular resemblance.

Trigonoscuta inventa.
PI. II, Fig. 3.

Body stout, compact, a little more than half as long again as broad.
Head small, finely punctate; eyes large, transversely broad-oval; antennal
scrobes scarcely oblique; rostrum shorter than the head, rather stout as
seen laterally, sparsely and not very finely })unctate. Prothorax apparently
fully twice as broad as long, densely and rather finely punctate; in front,
finely and transversely striate. Elytra coarsely puuctato-striate, the inter-
spaces with a single row of finer circular puncta, separated from each
other in the same row h}' lialf their diameter Anterior coxpe attingent,;
middle pair separated by a verj- narrow space, less than one-fourth the
diameter of the coxal cavity; hind pair vexy widely distant, nearly twice
the diameter of the coxal cavity. Femora large, long, clavate, punctate.
Tibiae moderately slender, not fiexed. First and second abdominal seg-
ments long, separated by a sinuous suture; whole under surface densely,

TENILLUS (r«Voj, 'AAr)?), gen. n<.v.

The length of the beak of this insect suggests at first that it belongs
to the C'ureulionidae, but the completely concealed nietasternal epiniera,
with the stoutness of the rostrum, indicate pretty clearly that it belongs to
the Otiorhyncliidaj. As the thorax shows no signs of po.stocular IoIk's or
fimbria-, and the antennal scrobes are lateral and curve down so as to ter-
minate beneatli the eye, it clearly belongs in the Brachyderini, but it can
not possiblv be refeiTcd to any of our living genera. The head is inoder-
atelv long, but the rostrum, a little arcuate, is nearly twice as long as the
head and apparently with a pair of sui)erior longitudinal sulci; the eyes
are broadly oval and longitudinal. The thorax is tapering without ocular
lobes or fimbriae. TJie first and second abdominal segments are subequal
and slightly longer than tlie e(|u;d tliinl an<l fourtli, all with di.stiuct and
simple sutures, as far as can be seen. Tibi;e a little arcuate, the third
tarsal joint apparentlv not wider than the second. It would seem to be not
far removed from Trigonoscuta and Calyptillus.

A single species is known, from Florissant.

Tribe OPHRYASTINI.

With the exception of a couple of species, referred to Ophryastites as
indicative of an alliance to Ophry<i.stes, and which come from Florissant, all
the fossil species of this tribe, relatively the most important of the family,
are characteristic of the Gosiute fauna. They consist of four species of
Ophryastes, two others of Ophryastites, one of Exomias, and four of Phyx-
elis. None of these genera have been elsewhere recognized in a fossil state.

OPHRYASTES Schonherr.

Excepting a single Siberian sjjecies, this is an exclusively American
type, much more abundant in north temperate America than further south.
The seven species found in the United States are all found in the western
half of the continent. Four species occur in the western Tertiaries, none of
them at Florissant, su that it would appear to be peculiar to the Gosiute

fauna.

A large, stout, short-snouted, but very imperfect specimen seems to be
nearly related to this genus. It is too fragmentary and imperfect to be
worth figiiring, and need only be mentioned as perhaps the largest beetle
discovered on the White river. It is fully as large as our largest species of
Ophryastes. The rostrum is hardly longer than broad; the thorax tumid
and longitudinally coarsely and heavily ridged; the elytra striate, witli
small, not very deeply impressed punctures; the interspaces elevated, Ijut
more or less flattened. The hinder part is broken off, but its full length is
estimated to have lieen about 15'5'°'"; the fragment is IS'.^™"' long and

OPHRYASTITES, gen. nov.

Under this generic name I propose to group such s^jecies as are
insufficiently represented, by elytra which can not be referred to other
known fossil species, but which agree closely, so far as can be told by these
elytra, with the same parts in other Ophryastini. ^Ihey all show a more or
less vaulted form, though often obscured by ])ressure, and nine series of
punctured stri;e, those of opposite sides of the elytron meeting near the
apex, to a greater or less degree, and sometimes accompanied by an im-
pressed line Ijordering either margin. Four species are found in the
western Tertiaries, at Florissant, the Roan mountains, and White river,
Colorado.

Tribe OTIORH YNCHINI.

Four species of Otiorhynchus, four of Otiorhyuchites, and one of Ne-
optocus have been found in our American Tertiaries, all but one (a species
of Otiorhvnchites from Florissant) belonging to the Gosiute fauna. None
of these "■enera have ever Ijefore been recog-nized in the earlier Tertiaries.
The only members of this ti'ibe recorded from the European Tertiaries are
five species from the Pleistocene, all regarded as identical with existing
forms, and a single species of Laparocerus from diluvial beds in Madeira,
mentioned by Heer.

OTIORHYNCHUS Germar.

This genus, now the most prolific in forms among all the Rhyn-
chophora, numbers its species by the hundreds, almost all of which are ge-
rontogeic. North America having but a scant half dozen, some of which
are identical with those of the Old World.

In Europe, the genus has been recognized in a fossil state only in the
Pleistocene, Heer and Flach having described three or four species or vari-
eties which are regarded as identical with living species. In America we
have refeiTed here four species, mostly known (like the European) from
their elytra; two of the species occur at Green river and two at the Roan
mountains.

OTIORHYNCHITES.

Ei-itsch has employed this term for the elytron of a Coleopterous insect
from Secondary rocks i)lainly l)elonging to the Rhynchophora. It is here
used for certain Tertiary elytra, most of them bearing a close resemblance
to those of < )tiorhynchus, merel}- to indicate their general afHnities. They
are much larger than our native species of Otiorhynchus. Four species are
described, two from the Roan mountains, Colorado, one of these also from
Cli-een river, and one each from Fossil, Wyoming, and Florissant, (Jolorado.

LACIINOPUS Schf.nhoiT.

A cliaractcnstic West ludian genus with about forty species. A single
one is found in Florida. That two species should occur in the Tertiary
beds of Florissant is an indication of the warmer climate of Olig'ocene times
in that region.

The species here referred to Lachiiopus are among the largest of our
fossil Rhynchopliora and much larger than the -single species living in the
United States, but smaller than many exotic forms. Tliey (or at least the
best known species) appear to differ from Lachnoi)Us in some inii)ortant
features, such as the direction of tlie antenna! scrobes and the length of the
scape, {jerhaps also in the form of the thorax; and though the two species
here described have somewhat difterently formed legs, the larger and least
known species agreeing best with living- Lachnopi, they }'et agree so well
in general features that it has seemed best not to separate them.

Family CURCXJLIONID^^i].

( )nc hundred, species, or slightlv more than one-half of the Tertiary
Rhvnchopliora of North America, Vjelon<^ to the Curculionidie, but this ]ire-
ponderance is a little less than in the recent American fauna where the family
holds a still more important place; and is the more conspicuous from the
fact that its numbers are more than four times those of any other familx',
while in the Tertiary deposits of the West the Otiorhynchida- have nearly
half as nianv species as the Curculionida'. In general, the relative
numerical proportion of the subfamilies is similar to what obtains in North
America at the present day, or at least the vast proportion of the species
belong as now to the Curculionina^ ; but the Alophina' possessed then a far
greater i)ercentage (eight times greater) than now, while the Balanina^ w.re
also relativelv iiiucii more numerous, the percentage of species to the whole
iiiiinlxr i>\' the family being then nearly five times greater; the loss fell on
the Curculioninic and to a small extent on the Apionina', while the Tthyce-
rinae, now represented l)v a single species, are not known to have i'xiste<l.

In Euro])e, if we regard the species of IIip])orhinns as Alophina-, the
i-elative jtreponderance of the subfamilies of fos.sil Curculionid;u approaches
nearer and indeed verv closcdy to the conditi<in of things in America to-day,
tor more than four-fifths of the species are to be referred to the ( "urculionina',
though the .\liipliina' are still nearK three times in excess of their present
American proportion, and the Sitonin;e have an even slightly greater icla-
tive preponderance. As in Ameri<a, all the subfamilies are present excepting
the Ithvcerina'. The total number of species, strangely enough, is <'xactly
the same as in America.

111 the United States, Florissant furnishes the vast proportion of the
Tertiary species in all the subfiimilies except the Sitoiiina', where two out
of the three come from the Gosiute fauna; V)ut it is curious to note one ex-
ception in that all the sjiecies of the first tribe of Curculioniiuv, the Phytono-
inini, and nearly all those of the second, the Hylobiini, also come from the
Gosiute fauna. The other species of the Gosiute fauna are scattered here
and there, but, all tdld, they form only one-fourth of the whole number of
species and represent only one-sixth of the genera.

Subfamily SITONIN^E.

As Sitona alone represents this subfamily among- the fossils the reader
is referred to that genus for general remarks. It may only be mentioned
that the g-rouj) appears to have been represented in Tertiary times in about
the same relative numbers as at jiresent.

This genus, rich in species, is confined to the northern hemisphere, and
IS especially at home in Europe and the neighboring regions. There are a

ora. The head is small, Avell embraced by the prothorax, finely and deeply
punctured, the ])unctnres usually separated from one another by their own
diameter, being represented too closely crowded on the plate; the rostrum
is stout, unifoi'm, and ncarlx' straight, scarcely longer than the short thorax,
broadly rounded at tlie apex, and faintly and finely })unctate; antennal
o-roove straight, extending nearly the entire lenoth of the i-ostriun and
striking tlie middle of the large transverse oval eye, not given in the figure.
Pi-othorax subglobular but nmch broader than long, studded profusely with
exceedingly large, shaip, and very deep ^junctures, more closely than repre-
sented on tlie ])late, nearU' ()•■_>""" in diameter, and giving the thorax the
appearance of a mulberry. Elytra together fnlly twice as wide as the pro-
thorax, each about twice as long as l)road, with series of narrow tuberculate
and punctate ridges and l)et\veen them series of distinct and sharp, pretty
large circular piuictures separated usually by twice their own diameter in
eacli row. Legs moderately long, the femora stout and transversely and
fineh' striato-})unctulate.

CONIATUS Germar.

It is on account of their rounded eyes and the tapering form of the
head and prothorax combined that I have placed here two sjjecies which
seem to be Alophinaj, but which can not be placed Avitli any other of the
genera, living or fossil, of this group. In one of the species, though not in
the other, the third and fourth segments of the abdomen are relatively
longer than in the other fossils of this family, and this is perhaps an indica-
tion that when better known these two species will have to ])e geuerically
separated.

The dozen species belonging to this group are all Mediterranean and
most of them European. A single species has been found fossil in the
European Tertiaries at Aix and two species in our western beds, one at
Florissant, the other in the Gosiute fauna. The European species has noth-
ing specially in common with ours and is half or less than half the size of

either of them.

Subfamily APIONIN^E.

Since l)oth in Euroi)e and in America, the only Tertiary forms of this
family liave l)een referred to the genus Apion ( which contains all but one
of the numerous forms now existing in America), the reader is retei-red to
that irenus for the general remarks that miyht he looked for here.

APION Herbst.

A genus enormously rich in species, of small size, distributed all over
the world, but absent from Australia, and principally found in the northern
hemisphere. About seventy species are found in North America, and, as
may be imagined, are widely distriljuted, the larger number, however, heing
found in the southern half of the coiuitry. Half a dozen fossil species ha\'e
been found in Europe, i)rincipally in Brunstatt, and as many at Florissant
alone, while an additional species has been found in the Roan mountain
beds. It appears, therefore, to be somewhat characteristic in this country
of the Lacustrine fauna.

All the species from Flori'^isant and the Roan mountains refei-red to this
o-einis appear to fall in the fourth section of Smith, in his last synopsis
of the species, and the Florissant species perhaps also in his group Ventri-
cosum; but the first species, at least, is very different from any of our modern
forms in the great length of the head, and in all but one of our fossil species
the eyes are farther from the margin of the prothorax than is conunon, and
the thorax is always more transverse. The same, too, may be said of the
other fossil species hitherto described from Brunstatt, Oeningen, and Rott,
by Fonster, Heer, and Heyden, six in number, if we separate, as I think we
must, the species described from Rott and the one from Brunstatt, doubt-
fully regarded as the same by Forster.

This, the largest of the Florissant species, differs strikingly from the
others and from all modem species known to me in the great length (if the
head, as well as in the great length and looseness of the antennal duh, so
that I ([nestion whether it shoidd fall here. The general form appears to Ije
as in the gronp Ventricosum. The head is considerably longer than the
thorax and longer than broad, tapers with full sides and rounded front nea)ly
from the base, and is nearly smooth but transversely wrinkled; the rostrum
is only ;i littlr longer than the head, very stout (for Apion) and equal, scarcely
aiTuatc, well rouiidi'd at the tip, with no expansion except at extreme ba.se;
the loose club occupies nearly two-fifths of the anteiuKV, which are longer
than the beak by the length of the apical joint. Thorax very short and
transverse, broadest at the base but scarcely tajiering, a little arched al)ove,
the surface very distantly, rather coarsely but not heavily punctate. Elytra
not clearly and fully jireserved in any specimen, but the striation appears
to be feeble, and their punctuation rather coarse. Legs with very stout and
large fore femor;i, but in no way abruptly clavate.

Viewed from the side, the dorsal aspect is strongly, arcuate. The head
is nearly as long as the thorax, rounded conical, the surface transversely
striate, beneath the eye |)unctate; eyes circular, not large, lying next the
base of the beak, which is porrect and slender, but in the single specimen
known is broken a little beyond the base; so far as can be seen it has exactly
the aspect of tliat of A. curiosnm. Thorax about half as high again as broad,
scarceh' tapering, very gently arcuate above the surface, with large and
distant punctures, very different from those of any of the other species.
Elytra apparently somewhat larger at base than the })rothorax, very ai-cuate,

ciucn.ioMD.i': — ciKcii.ioNiN.i: — I'IIvi'onomini. s7

Here it will readily be seen that the {•reatest and the mily cnuspicuous
difterences between the AiiMiicaii ;nid Hnropean 'l\'rti;iriis lie, dii the one
side, in the ( 'Icdiiiiii, wliicli cniitaiii iicarK' mic-tliird of the Onrfulidnina- of
the European deposits, and hardly more than 7 per cent of those of tlie
Aincrican: and on the other side, in the Authoiioiiiini, whii-h do not exist at
all in the Knroj)ean Tertiaries, l)ut form nearly onc-foiirtli of the American
TertiarN- Curcnlionina', and in the Harini, which comprise nearly IG ])er cent
of the American Curcnlionina' and hardly 3 per cent <A' the European. No
such striking ditiereuces appear in comiiaring- the numerical preponderance
of the tribes in the recent and fossil Curculioniih-e of North America, the '
jrreatest disparitv apjjearing in the reverse proportions of the Anthonomini
and the Crvptorhynchini, the former heiny relatively more than twice as
important in the Tertiaries as now, the latter more than twice as important
now as in the Tertiaries, and in the Ilylobiini, where the fossils, thouofh not
numerous, formed 10 per cent of tlie total fauna in Tertiary times, while
thev hold only one-fourth of that j)erceutage in the existing fauna; a rela-
tion again nearly reversed in a group of greater importance in recent times,
the Phytouoraiui, where the percentage to the whole fauna is now nearly
three times jn*eater than it was in Tertiary times. In all other cases the
difference between recent and Tertiar\' times, where the trilie was rejjre-
sented at all, is insignificant. In all these cases of distinction between the
recent and Tertiar\ representation, excepting oidy in the Phytonomini, the
disparity would have appeared still greater if the Tertiary Curculioniiue of
Ein-oi)e had been compared with the recent fauna of North America; from,
which we may conclude that as far as the Curcnlionina' are concerned, the
Tertiary fauna of America shows (doser relationshi]) to the existing Ameri-
can famia than does the European Tertiary fauna.

PACHYLOBIUS LeConte.

A North American genus of only one or two species, confined to th«'

and lu'ing apparentlv peculiar to the Go.siute fauna, may be regarded as
one of its tvjjical forms.

The three species from the Rocky mountain Tertiaries here entered
imder Pacliylobius are so placed from the close resemblance of their elytra
:ui<l from the structure of the body of the first of them, wliiili aicor<ls well
w ifli that of this genus. Here the head, forced beneath the thorax, can
mil v l)e seen to have rather large, oval, low-placed eyes, a relatively hmg,
moderately stout beak with scrobes running with little obli(|uity to the eyes,
a somewhat tumid prothorax hardly if at all longer than broad; the middle
coxa; are slightly sejjarated, the hind cox» much further removed from each
other, the first abdominal segment sending a triangular process between
them; the metasternura has a slight blunt median carina barely flanked by
slight carime; the suture separating the first and second abdominal segments
is considerably arcuate iu its middle half; the third and fourth abdominal
segments are together considerably longer than the mass of the second, and
the fifth is relatively .short. Not all of these characters distinguish Pacliy-
lobius, so that it is questionable whether the reference can be strictly made.

LACCOPYGUS (XaHH67rvyo<), o-en. nov.

We have here a very striking genus of llylobiini, remarkable ])articu
larly for the structure of the funicle of the antenn;e, by whiidi it seems
nearest allied to, though still somewhat distant from, the Mexican Laccojjroc-
tus. The head rapidly narrows in front, and the rostrum, large at base, also
narrows a little, ])ut i.s still rather stout and considerably shorter than the
th(H'ax. The antennal scrobes extend almost to tJie lip, and the .-^lender,
apicallv clavate scape reaches the posterior' border of the eye; the funicle
is composed of seven similar elongate joints, subequal, excepting the second,
which is twice or more than twice as long as any of the others, and, with
those on either side of it, fullv equals the scape in length; the chd) is stout
oval, and the seventh joint of the funicle in no wav invohed in it. Kves
lather small and round. Thorax exce])tioually short, being full\ half as
l)roail again as long, with gently convex sides and truncate extremities.
Elytra moderately elongated, considerabK bida<ler at base than the ])ro-
tiiorax, not al)ru|)tl\ declivent behind. Fore femora exceedinglv >tont; all
the tiliia- slender; lirsi joint ot' tarsi elongated, more than twice as long fis
broad, slender at base ; second a little inore than half as long, oval; third

Tribe CLEONINI.

This is one of the most important tribes of ( 'urculionina- in the
Eui-opeau Tertiaries, no less than half a dozen genera with twenty-two
S])ecies being recognized, and, af, Oeningen at least, tlie species are abun-
dant in individuals.. These genera are Khinobatus, recognized at Aix by
Hope and Serres; Lixus, with two species, at Oeningen; Rhinocylhis, with
one species, at Kott; ( !leonus, with fom-teen species (the largest nundier
referred to anv one genus of ( "urculionida^ or, indeed, of Khynchophora,
excepting the magazine genus Curculionites), from Oeningen (6), Corent
(2), Aix (6), and Brunstatt (one species found also at Aix). It is a far less
important ingredient of the Tertiary fauna of North America, and is con-
fined to Florissant, Avhere five species occur, all but one also referred to
Cleonus, the exception being distinguished as an extinct generic type under
the name of Eocleouus.

Lixns, were not the head so much longer, it being more than half a,s long as
the ])rothorax, and the arcuate, equal, bhnit-pointcd snont scarcely longer
than the head; tlu^ eye is circidar and not vcr\- hirgc, situated in tlie middle
of the head; the scape of the antennai does not extend back to the base of
the snout by the length of the first joint of the funicle, while tlu; fnnicle
alone is nearly as long as the snout, its first joint slender and longest, the
remainder stout and subequal, the seventh snbglobular and in no wav form-
ing a jiart of the large fusiform club. The thorax is of about equal height
and length, scarcely tapering. The base of the ehtra is sinuate. The fore
legs are rather slender and not very long.

America, which possesses about twenty-five species, all of them restricted
to the western half of the continent. No genus of Rhynchophora (except-
ing that refuge for vague and ill-defined forms, Curculionites) has been so
widely recognized in a fossil state. Half a dozen species have been figured
from Aix alone, and one of these has been recognized also at Bmnstatt, half
a dozen or more others at Oeuingen, besides tw^o at Oorent. In this country
four species have been found at Florissant, none elsewhere, this being the
only genus of Rln-nchophora I know which is so much more richly devel-
oped in Europe than in America. It may be doubted, however, whether
all the European fossil species should be placed together. Of these species,
our C. forrsfi'ri seems to bear closest resemblance to Oustalet's C. arvenensis,
from Aix; our C. exterraneiis resembles not a little the same author's C.
■inflcxm from the same place; and our C. primoris is not very far removed
from Heer's C. aspernlns, again from the same; while our C. dcgcneratns is
altogether different from anything found in the l^^uro{)ean Tertiaries.

nized by Curtis at Aix; Dorytomus, recognized by Serres at Aix; Erycus,
two species in the Pleistocene of H(")sbacli; Smicroiivx, one species at Brun-
statt; and Erirhinoides, an nncharacterized extinct genus, with one species
in amber. In America we lind seven genera and nine species, all of which,
Avith a single exception, come from Florissanr. < >f the genera found also in

ERIRHINUS Schonherr.

This is an Old World type, the species from North America formerly
placed here being now regarded as distinct. It has been recognized as fossil
by Oustalet in a single species at Aix, and one has been indicated from amber
by Motschulsky, under the name Erirhinoides.

The species here included in this genus is so placed onlv as typical of
the Erirhinini. Its much briefer rostrum, as well as the exceptional size of
the head, forbids its being classed here in any strict sense; Init as I can find
no genus to which it appears nearly allied among our Erirhinini (to wliicli
from its general characters it ap])ears to Ix-long, although tlic abdominal
segments are equal in length), it is provisionally placed here.

Tribe MAGDALINI.

This tribe, composed in America of the single genus Magdalis, is repre-
sented by this genus alone in the Tertiary deposits, whether of Europe or
America. In Europe two species have been described from Rott; in America
one only is found at Florissant.

MAGDALIS Germar.

A genus rather richer in forms in Europe than in North America, where
we recognize seventeen widely-distril)uted s[)ecies, while a couple of species
are found in South America and one in Australia. Heyden describes a couple
of species (Magdalinus) from tlie Tertiaries of Kott. I place here a single
fossil species fi-om Florissant, which, from the general character of the
antemije (though the jointing of tlie funicle is not clear), and the prominent
hind angles of the prothorax, as well as by its general aspect, seems to
belong certainly in its neighborhood, but which, after all, differs considera-
bly froni it in the structui-e of the elytra and the 'early insertion of the
antenna?, b}' which the scape is made to reach the very middle of the eye.
Both the species described from Rott, and especially 31. deucal'wnis, are
much larger than ours, which resembles M. deucalionis rather than the other,
but is still well removed from it.

Tribe ANTHONOMINI.

This tribe, now represented in .\merica l)y a considerable number of
sjjecies, though not rich iu generic types, and entirely ab.sent from Knropean
'I'eitiary deposits, is one of the most iinjjortant of the ( "urcidionina- in the
'I'eitiaries ot' America, the innnber of generic tvpes whi(di have been dis-
covered being as great as Jiow, KUesclius being the oid\ one not recognized,
and its place is made good by an extinct type, Creniastorhynchus, with a
single .species. Acalyptus, Orchestes, and .Macrorhoptus have ea(di a single
species, Coccotorus two, and all of these come exchisivelv from Florissant:
as in the existing fauna, however, Anthonomus is far the best represented,
being in fact the richest species of any ot' onr fossil Ulniichophora, having
ten species tolerid)lv niunerous in individuals, and all but two, which come
Iroin the Gosiute fauna, are like.wise restricted to Florissant.

feebly striate; the eye circular, of aliout the diameter of the beak, with
about sixty large facets, each slightly less than OOl ;")""" in diameter; the
beak is long and slender, somewhat longer than head and thorax together,
gently arcuate and equal. The antenna? appeai- to be inserted and formed
precisely as in A. rufipcnnis, with the same proportional lengths, so far as
can be seen; the clul), however, is ol).scure. The thorax is well rounded,
tapering, about half as high again as long, very coarsel}' pimctate. The
elytra are well arched, much broader in the middle tlian elsewhere, and
rather coarsely ])unctato-striate, and the intersj)aces show feeble signs of

CREMA8TURHYNCHU8 {xP^I-^'^'^rb?, pvy/j)^), o-cm. nov.

The insect to which this name is given is vinqnestional)ly nearly alUed
to Antlionomus and Coccotorus, so far as its stnicture can be told. But it
dift'ers from them so clearly in one point, that I venture to separate it, viz,
in the simiosity of the suture at the sides of the body between the first and
second abdominal segments, a ch.aracter which I do not find in any other
genus of living Anthonomini. In other respects it closely resembles the
species I have here placed in Coccotorus. The beak is almost straight, and
nearly as long as the head and prothorax together; the eye large and trans-
verse, but not ajjproximate abo\'e; all the femora are stout, but inoi-e strongly
clavate, and the segments of the abdomen are of suberpial length.

A single species is known, and comes from Florissant.

can not be determined with certainty.

Macrorhoptus intutus.
PI. VI, Fig. 5.

To this genus I refer a single species with large transversely oval eyes,
not closely approximate above, but so closely as to make the front narrower
than the beak, with obtuse hind angles to the prothorax, and with all the
aspect and structure of one of the Anthonomini. The head is about half as
high again as long, with a finely jmnctate surface; the beak is somewhat
longer tlian tlie prothorax, somewhat arcuate and equal; the antennal serobe
scarcely attains the eye, and is apparently inserted slightly beyond the
middle of the beak; the funicle and club together are slightly Imiger than
the scajjc, and slender, the Hnal joints of the funiculus grachially enlarging
to the gentle club, nuich as descril)ed for M. rstrhifns Lee, Imt slenderer.
Thorax uuu'h nmre than half as high again as long, well rounded, not taper-
ing greatly, ratlier coarsely punctate. Elytra fully twice as long as broad,

Tribe TYCHllNI.

This small tribe is ver}- similarly represented in the Tertiaries of
Europe and America. In the former are found one species of Sibynes, at
Aix; and two of Tychius, at Rott and Rrunstatt : in the latter one of
Sibynes and two of Tychius, all at Morissant; in no otla-r tribe of Rhyn-

and Central and South America only about as many more. Two species
have been found fossil in Europe and two in America, the latter at Florissant
only. One of the European species, T. manderstjcrnai Heyden from Kott,
appears to l>e cjuite too large for a Tychius and is preserved in such a
position as hardly to allow jn'oper comparison witli the American fossils;
the other, T. latiis Forster from Brunstatt, differs much from the American

RHYSOSTERNUM (pu(j6?,GT£pvov), gen. nov.

Having the general aspect of Rhyssomatus (to which the late Dr. Le-
Conte called my attention), but with an unusually long l)eak, pi-ominent
postocular lobes, and altogether different sculpturing of tlie elytra ; it would
appear, liowever, to l)elong in tlie same group. Body ovate, somewhat
elongate. The beak is longer tliau tlie head and thorax together, sometimes
more than twice as long as the prothorax, and strongly arcuate. The an-
tenna? are not very clearly ])i-eserved, but the funiculus and club together
are fully two-thirds as long as the l^eak, and apparently the first joint of the
former is long, while the succeeding are much shorter and subequal, the final
ones lialf as broad again as the second. The prothorax is nuudi liighertlian
long, with prominent postocular lol)cs, due largely to a dee}) angular rounded
emarffination at the middle of the sides; its surface is sinuateh' and loiio-i-
tudinally strigose, as in Rhyssomatus. The elytra are simply but \cr\- dis-

CEUTHORHYNCHUS Clennar.

A prolific genus with a couple <:if hundred species, almost exclusively
confined to the Old World. We have, however, nearly twenty species in
North America, widely distributed. Four species have been found in the
p]uropean Tertiaries and five in the American, almost confined to and
somewhat characteristic of the Gosiute fauna, only one of the species
occun-ing elsewhere. The European species mostly occur at Brunstatt, C.
ohUquus Forster being very chtse to our (J. couipKcta^;, but the species from
Rott bears no special resemblance to any of tlie American species.

Tabic of the KiH'ckfi of Ccufhorhynchus.

Base of elytra scarcely or not at all wider thau the thorax.

Body twice as long as broad, the general form relatively long oval.

Prothorax nearly or quite twice as high as long ; i-ostrum shorter than head
and thorax together.
Prothorax fully twice as high as long, verniiculate; rostrum stont.cvinctus.
Prothorax nearly twice as high as long, punctate; rostrum relatively

slender clausns.

Prothorax hardly more thau half as high again as long; rostrum longer than

head and thorax together ditraiiin.

Body much less than twice as long as broad, the general form relatively short

oval compactu^.

Base of elytra much wider than base of thorax degravatus.

Ceuthorhynchus evinctus.

Head broad but short and not very full, not very finely but densely
punctate; eyes large, very broad ovate, transverse, midway in height:
rostrum stout, gently and regularly arcuate, a little longer than the pro-
thorax, finely and feebly striate. Prothorax without postocular lobes, fully
twice as high as long, roundly but feebly tapering from the base, beneath
very full, the surface coarsely verniiculate. Under side of thorax very
'coarsely and somewhat sparsely but distinctly jiunctate, of the abdomen
feebly punctate. Elytra with alternate costaj and sulci, the latter deeply
and distantly pierced with more or less longitudinal pn ^cta.

This tril)e is far better developed in the American than in the European

Baris, one (undescribed) at Aix, the other at Brunstatt; while in America

BARIS Gerinar.

A genus exceedingly rich in species, of which over two hundred and
fiftN' are catalogued. Although represented to a lertain degree in nearly
every part of the globe, America, possessing about three-fourths of the
species, must be regarded as its ])roper home. \'>y far tiic larger part are
found in South and C!entral America, an<l tlic sixteen or seventeen species
which North America possesses are found largely in the Southern states.
The jrenus is not unknown in the Tertiaries. Lonj^ since Serres indicated
its presence at Aix, in Provence, and Foerster describes one species,
Baridium uaviculnre from Brunstatt, Alsatia; while at Florissant, Colorado,
no less than four species occur. F,\cepting B. (livisa, ;dl the species are very
much stouter than the Brunstatt form, which has a so nmch stouter rostrum
as to make it doubtful if all can l)e placed in tiic same genus. The
species we have entered here are placed in this l;cMius mcrcK as t\ pical of
the group, but one, 11. Iidrldiii. seems moiv stricly in jilace than the others.
It is altogether probable that, were their characters fully known, they

This family w^as not very well represented in America in Tertiary times,
its proportion of species to the whole body of Rhynchophora standing some-
what below the present proportion. One of its existing subfamilies, the
Rhinina', represented ii\ America to-day by only a single species, is unknown
in both the Pkiropean and American Tertiaries, but the other two sul)families
occur in each country, and in proportions not greatly fliffering from those
now exi.stmg, though in l)otli countries the Cossonina? appear to stand a little
above, the Calaudrina' a little below, their present numerical importance.
The total number of fossil species known is sixteen, of which the larger

8(TABRE(t]\IA (o)ud, /ipeyjja), gen. nov.

This name is projjosed for what is certainly a i-emarkable form of Ca-
landridge, or, indeed, of Rhynchophora, in which the upper anterior i^ortion
of the prothorax is produced to form an overarching frontal guard to the
headj'nearly or cpxite as long as the I'est of the prothorax itself There are
man}' Rhynchophora, whicli, from tlie emarghiation of the sides of the
prothorax to luu-over the otiicrwise jtartl}' (H'lipsed eyes, appear, on a side
view, to show a tendency to some forward ])roje{'tion of the upper jiortion,
but on viewing them above, nothing of the kind appears. Here, however,
the front is prolonged to an excessive distance, <nid cnrves downward in
addition, thoroughly protecting the head, hut in no way interfering A\ith
the drooping beak. A similar development is seen in some exotic Curru-
lionidse, as Plagycorynus, Anchonus, and Pileophorus.

It appears to resemble most the Sphenojihorini, tliough the needed
characteristic parts to determine this are not preserxed. The liead is short,
the beak gently curved, nearly or quite as long as the body of the jirothorax,
slender, growing gradually stouter at the l)ase; the eyes are small and
circular. Tlie prothorax, iucliidiiig rlie frontal projection, is coarsely rugose.

ORYCTORHINUS {opvurd^^pi?) gen. no v.

The general appearance of this insect, with its long metastemum,
throwiiig the insertion of the hind legs well behind the middle of the body,
makes it clear that it })elongs to this family. Its great size, and the exposure
of the pygidium, bring it into the subfamily ("alandrina', and the shape of
the mesothoracic and metathoracic epimcra reipiircs that it should l)c refeired
to the Sphenophorini. That it can not be referred to any existiug genera
of this group — at least any legarding which 1 liaxe been al)le to obtain
infoiTTiation — is clear; for thougli the mesothoracic epimera are externally
truncate, they are narrowed and rounded at the outer antei'ior angle, much
reducing the breadth of the truncation, and, besides, the club of the antennjt
is oval and not wedge-shaped, in both features showing a decided affinity
to the Calandrini. The antenn;c are unusually small and slender, the entire
length of the funicle and clul) combined being hardh more than twice the
width of the rostrum, and the scape being no longer than the distance of
the insertion of the antennfe beyond the base of the rostrum. The anterior
coxae are separateil b\- a little less than halt' tlic width of the coxal cavities,
that is, not very narrowly; the mesothoracic coxa' bv a little less than the
entire width of the coxal cavities; and the metathoracic cox;v by a very
little more, a feature which appears to be quite exceptional.

sternum is a])})areutly long and the fnnicle of the antenna? is corapo.sed of
numerous, probably seven, joints; the ej'es, too, are situated almost upon
the beak, and are composed of relatively few lenses, bitt are not prominent,
and the head has the slightest possi)>le constriction behind the eyes, a little
in advance of the middle. The body is elongate. The head is of excep-
tionalh' great length, though only half as long as high, subcorneal, with
rounded contours; the lieak is as long as the jjrothorax, moderately stout,
equal, and very gently curved; the antenna? are inserted at three-fifths the
distance from the base, have a slender scape reaching nearly to the eyes, a
fuuicle of apparently seven, so far as can be seen equal and quadrate, joints,
together as long as the scape, and an elongate oval club, several times
longer than l)road and fully twice' as broad as the funicle; the eyes are rather
small, short oval, obliquely transverse, the front margin overlapping the base
of the beak. The prothorax is cylindrical, even, hitiher than lono- • the leo-s
rather slender and not long, and the elytra ridged; the pygidium is apj)ar-

aspeet of a Gononotus, but with a shorter and straighter rostrum, and i\o
rounded protuberances on the prothorax, though the sculpturing is in gen-
eral similar. Head verv sliort: the beak is about two-thirds as Ion"- as the

Family SCOL^^TID^E.

No famih' of L'hvnchojjiiora is so mucJi more ])oorly re))resented in
Tertiarv deposits than in the living tauna as the present. This must doirbt-
less be accounted for in large measui-c b\ the habits of these insects, living
as thev do beneath the bark of trees, and therefore less exposed than the
members of the other families to such accidents as woidd precipitate them
to the bottom of lakes and p(mds. In our own countr^' they fonn less than
3 per cent of the Tertiarv Khvnchophorous fauna, while in the existing
fauna they compose more than to j)er cent of the whole. The Platypodinae
are represented in the Euro])ea-n IVrtiaries by a couple of amber species
of l*lat\pus, l)ut arc not found in our rocks, while the Scolytiujc have the

A dorsal view of a single si)ecimen showing prothorax and^lytra is all
that is preserved. Tlie prothorax tapers rapidly forward, 'o-ith rounded
sides and a stronglv convex front, giving a ])araboloid curve to the front
of the body; il sliows a verv faint median longitudinal impression and is
pretty uniformh- punctate, the puucta showing a tendency to a longitudinal
arrano-emeut, being more distant from those at either side than from those in
front and behind: there are besides some finer punctuations on tin- ilisk.
Elvtra more tlian half as long again as their eombined breadth, broadest in
the middle and then rapidly tapering so as to make the form of the body
])yvt\y regularly long oval; the elytra are more distantly punctate tlian the
prothorax. but the i)uncta are slightly larger and arranged in tolerably
reo-ular serial rows, in all about a dozen rows, separated by twice the
diameter of the ])uncta, the puncta of the same row similarly separated.

160 TERTIARY RHYXCHOPHOROUS OOLEOPTERA.

Family ^T^THRIBTD^E.

In the American Tertiaries tliis family is nnnsnally well developed, its
|)r<.|i(irti()nal rcpivsciitation being- considerably above what exists to-day.
The relative nmnbers of the different tribes are similar to what we now
hnd, and all the tribes are present except the Xenorehestini, which is tlie
sniallesT to-dav. The nnmliers of the Tropiderini, however, are above
their })resent pr(,)portion, and those of the Arjeocerini below it. In the
European Teitiaries neither the Tropiderini nor the Xenorehestini occur,
while the. actual numbers in the other groups are precisely as in the Amer-
ican rocks. The total number of European fossil species is scarcely more
than half that of the American.

Tribe TROPIDERINI.

This tribe is whoUv wanting- in the European Tertiaries, but is very
well represented in ours, liaving- five species of four genera, of which two
from Florissant, with one .species each, represent extinct types, wliile tlie
others are referred to Tropideres, one species each from Florissant and
Green Eiver, and Hormiscus from Clreen River.

SAPERDIRHYNCHUS (Saperda, nom. gen., fSvyxo?), gen. nov.

This striking genus of Anthribidie d(»es not fall in any of the gi-oujis now
recoo-nized as living in North America, but rather belongs to one allied to
our Ischnoceri termed Discotenides by Lacordaire: for the immensely long-
antenna' are inserted on the sides of the rostrum, the antennal scrobes are
circular and termiiial, the rostrum is at base smaller than the head, the eyes
are rounded and not longitudinal, and the prothoracic ridge is prebasal.

This group, as defined bv Lacordaire in 1S6(), consisted of only three
fj-enera, two of which were found in islands of the South Pacific ocean, the
third, Discotenes, in Brazil. The present forni is not very close to that
o-enus, having a much shorter thorax, and autennse of different construction,
somewhat resembling Cerambyrhynchus, a genus of another group found
onU' in the Pacific islands. The following are some of the details of the
stracture of the fossil type.

ANTnRFHID.T:— TROPIDERna. 161

Head miidi linijivr than liig-h ; nt.struiu nearly twice as loiiji- as the rest
ot the liead, the front border arcuate; antennal scrobes subcireular, shaqtlv
definf'd, separated from the tip l)y less than their own width. Antennfv
fnlly hiilfas long again as the body, slender, first joint globose, second of
similar length but smaller, and shaped like the apical portion of the succeed-
ing third to ninth joints, which are elongate, subequal, apically clubbed, the
enlarged apex of the ninth forming with the two succeeding, which are half
as long again as broad, an elongate oval club about twice as stout as
the stem of the middle joints. Eyes small, oval, transverse. Prothorax
apparently quadrate, slightly tapering, scarcely so broad as long. Elytra
considerably longer than head and prothorax together, gently arched. Legs
slender, the front pair similar to the others.

A single species occurs at Florissant.

Saperdirhynchus pkiscotitillatou.
PI. I, Fig. 12.

Head (including also at least the basal half of ro.strum, prothorax, and
elytra) uniformly, finely, closely, and rather delicately granulate, the granules
circular except on the elytra, where they show a tendency to become longi-
tudinal, the cause perhaps of their presenting a pectinate appearance,
though this is more probably due to the linear arrangement of the long re-
cumbent hairs, which lie in series about a fiftieth of a millimeter apart;
the elytra also show faint moderately narrow ridges about one-fifth of a
millimeter apart more clearly on one stone than on the other. Antenme
clothed sparsely with recumbent hairs half as long as the width of the
joints; the joints are better shown on the vertical than on the oblique an-
tenna on the jjlate.

Tropidekes vastatus.
PI. II, F\^. 18.

A single specimen, not very (dearly preserved, lying upon its side,
represents this species. It is clearly related very closely to Tropideres, if
it does not belong to the genus in the restricted sense in which it is used by
LeCoute. It seems to have been moderately stout, uniformly black, and
uniformly, densel}', an<l very delicately granulose, or shallowly punctate, it
is hard to say whicli. The beak is moderatel}^ stout, shorter than the head;
it is badly represented in the plate, having an appearance wholly unlike a
Tropideres; the antenna' not nmch longer than the beak, the club composed
of three subequal joints, fully twice as ])road as the preceding, together
forming an oval mass about two and a half times longer than broad; the
eye is round oval, entire, transverse, and moderateh' prominent. The pro-
thorax is largest, though but slightly, at the prebasal ridge, and tapers for-
ward remarkably little; the elytra have rather finely punctured strije, so
closeh' crowded as to give the strife the a|}pearance in the cast of nearly
continuous ridges.

STIKADERES (^Oreipa, Siprf)^ gen. nov.

An insect is placed in tliis m^w generic category which appears l)y its
general aspect, moderately short antemise, and entire eyes to belong to
the gi-oup Tropideres. It is maiidy to Ije di.stingui.slied for the po.sition of
the prebasal prothoracic ridge, which is rectilinear and situate(| so far from
the ba.se as to be .slightly in advance of the middle of tlie prothorax, a
character which certainly occurs in none of our genera, and is apparentlv
uni(pie. The beak is unfortunately not well preserved, but is ap])arentlv
shoi-t, not greatly longer than the large, broad-oval, obliquelv longitudinal,
prominent eyes. The antenna' are a little longei- than tlie head and pro-
thorax together, rather stout, the middle joints not moic than twice as long
as liroad, scarcely larger at apex than at base, the three apical joints (piad-
rate or even broader than long, hardly broader than the preceding, the last
very bluntly rounded at tip, almost truncate.

A single species is known and comes from Florissant.

Tribe BASITROPINI.

If the Tophoderes described by Heyden from Rott belongs here, this
tribe is equally represented in the European and American Tertiaries. In
Europe, besides the species mentioned, an amber species (undescribed)
has been referred by Berendt to Anthribus, and three species have been
referred to Anthribites, two from Oeningen, and one, known only by bor-
ings, from Niederlausitz. In America we have a species of Anthribus from
Florissant, one of Brachytarsus from Green River, and three of Cratoparis,
one from Florissant and two from Green River.

ANTHRIBU8 Geolfroy.

The species of this typical genus of the family, not numerous, are

with a large l>lack impressed triangle, the ajiex forward; the eyes are
moderately large and transverse, the beak shorter than the head, apically
narrowed as seen from the side, the antenna^ nearly half as long as the body
and coarse, but unfortunately too poorly preserved to show the joints ; nor,
indeed, is there any apical enlargement to a club, so that probably they are
broken. The prothorax is well rounded, the surface very faintly, very
sparsely punctate, the ridge completely basal. Elytra faintly striate.

species, found in the Atlantic States. The discovery of no less than three
species in our Tertiaries, one at Florissant, Colorado, and two at Green
