CamBRIDGE, Massacuusetts, December 22, 1897.
Sir: I send herewith for your acceptance a descriptive account of the
Adephagous and Clavicorn Coleoptera of the Tertiary beds of Florissant,
Colorado, together with a catalogue of the non-rhynchophorous fossil
Coleoptera of North America, intended as a complementary volume to my
Monograph, already published by the Survey, on the Tertiary Rhynehoph-
orous Coleoptera of the United States.
Very respectfully, yours.

ADEPHAGOUS AND CLAVICORN COLEOPTERA
OF FLORISSANT.

By Samuret H. Scupper.

INTRODUCTION.

In Monograph XXI of the United States Geological Survey the
rhynchophorous Coleoptera of North America are fully treated. It was
considered as ‘‘a first installment toward a history of our fossil Coleoptera,”
which it was then intended should be followed by several other similar
volumes treating in succession the other great divisions of the Coleoptera.
The reasons for first undertaking the publication of the Rhynchophora
were given in that volume. Work had, however, already progressed at the
other end of the Coleopterous series, as explained in my report of July 1,
1887,! and at that time nearly all the descriptions in the present volume
had been drawn up. Change of circumstances has prevented me from being
able to carry out the work as I had planned, and accordingly the present
volume has been undertaken to complete temporarily the Coleopterous series.
All the hitherto published non-rhynchophorous Coleoptera are catalogued,
and in their proper place are given descriptions of all new forms and of those
few species (five in number) and genera (two) which had been published
in scattered papers by the United States Geological and Geographical Survey
of the Territories. These new descriptions are almost exclusively confined
to the Adephagous and Clavicorn families, and include all the species in
these families known to me from the Florissant basin. Those from other
Western deposits have not been studied or, indeed, assorted from the con-
siderable mass of still unstudied material in my hands, most of which has
come into my care within the last nine years, i. e., since these studies were

undertaken.

1Kighth Ann. Rept. U. 8. Geol. Survey, pp. 188-189.

12 - TERTIARY COLEOPTERA OF NORTH AMERICA.

The volume is, therefore, mainly a treatise on the Adephagous and
Clavicorn Coleoptera of Florissant, but is at the same time a catalogue of
all hitherto known or here published non-rhynchophorous Coleoptera of
North America (26 families, 125 genera, 210 species) As in the volume
on the Rhynchophora, I have prefixed to each genus and family a summary
of our knowledge of the extinct forms in the given group, brought up to
the date of writing (August, 1896).

I still retain the hope of completing the history of our fossil Coleoptera,
if not by extended memoirs embracing long series, at least by the publica-
tion of more limited papers upon separate families. The material therefor
is vast, but other engagements prevent rapid execution of my desires.

DESCRIPTIONS OF SPECTES.
CARABID &.

More than two hundred species of Carabidee have been found fossil,
referred to fifty-four genera, of which six are regarded as extinct. Thirty-
two of these species, belonging to fourteen genera (of which only two are
not otherwise recorded as fossil), are referred to existing species and occur
only in the Pleistocene of Kurope. Omitting these, there are one hundred
and seventy-two fossil species, of which fifty-four (of twenty-four genera)
belong to the Pleistocene, twenty-seven species of fourteen genera in the
Old World, and the same number of species of ten genera in North America.
From the older Tertiaries, one hundred and eighteen species are known of
forty-four genera (six extinct), viz, eighty-five species of thirty-four genera
(five extinet) in the Old World, and thirty-three species of twenty-six
genera (one extinct) in the New World. No species have been found on
both continents. Of the forty-four genera from the older Tertiaries, thirty-
four are found in the Old World, nineteen in the New, and nine in both.
Fourteen genera are represented both in the older and latest Tertiaries.

CYCHRUS Fabricius.

The only fossil species of this genus known are the two here recorded
and one other, C. rostratus Linn., a recent species, stated by Flach to occur
in the Pleistocene of Hosbach, Bavaria.

CARABID. 13

A fossil species from Wyoming, formerly described by me as a Cychrus,
has been found to belong to the Carabini.

The existing species of the genus, which are numerous, are mostly
found in north temperate America and Europe.

CYCHRUS WHEATLEYI.

NOMARETUS LeConte.

As existing to-day, this is a genus with few species, confined to the
United States east of the Rocky Mountains. No other species than the one
here described has been found fossil.

NoMARETUS SERUS sp. nov.
Pl. 1, fis. 1.

About the size and of much the general appearance of N. imperfectus
Horn. A single well-preserved specimen, showing nearly all the parts of
the body. It has a remarkably broad and little elongate head for this
group, but the whole form, the character of the appendages, and the deeply
cleft labrum indicate this place for it. The head is fully three-quarters as
broad as the thorax, tapering rapidly in front of the somewhat prominent
eyes, so that the labrum is rather less than half as wide as the head; and
before the labrum about as long as broad. The labrum is somewhat
obscure, but it is apparently two-thirds as long as broad, very deeply
and widely cleft. Mandibles moderately stout, finely pointed, and rather
strongly hooked. Maxillary palpi moderately slender, about a third as
long as the antennze, the penultimate joint gradually enlarged at the apex,
the last joint subtriangular, angulate in the middle, twice as long as broad

14 TERTIARY COLEOPTERA OF NORTH AMERICA.

Antenne nearly as long as the elytra, with the basal three joints larger and
more rounded than the succeeding; but the preservation does not permit
of noting what joints were glabrous. Pronotum subquadrate, broadest in
the middle, tapering gently in front, rapidly behmd,; front margin broadly
convex with no median excision, the lateral angles well rounded ; posterior
border produced somewhat, roundly angulate, the disk strongly depressed
in a longitudinal mesial band, broadening anteriorly ; lateral margin simple.
Elytra very regularly ovate, nearly twice as broad as the pronotum,
broadest a little behind the middle, the strize, apparently to the number of
about a dozen on each elytron, similar and slightly impressed, the outer
border narrowly margined.

Length to tip of maxille, 7 mm.; breadth across elytra, 3 mm.; length
of antennee, 3.5 min.

Florissant, Colorado, one specimen, No. 12086.

NEOTHANES Scudder.

An extinet genus, founded upon the present species, allied to Carabus.
The species was formerly referred by me to Cychrus, but evidently belongs
to the Carabini. The genus is described in my Tertiary Insects.

CARABUS Linné.

A widespread genus, prolific in species, found in the north temperate
regions and in a few south temperate districts. Three of the existing
European species have been reported from the Pleistocene of Switzerland,
England, and Poland, and as many more extinct species from the Pleisto-
cene of Poland. Omboni also figures a species from the marls of Italy.
But excepting that the genus has been recognized in amber, no species but
that here described has been noted from the earlier Tertiaries.

CARABIDZ. 15

SARABUS JEFFERSONI Sp. nov.
Pe hos Gs 0)

Two entirely different specimens are referred here to a single species,
one of them showing the head with the appendages, the other a nearly
pertect elytron. Both are of about the size of an ordinary Carabus, and
though neither agrees well with that genus in certain particulars, there
seems to be no other with which they agree so well. The head is smooth.
slightly tapermg forward, just as broad behind the eyes as the length to the
tip of the emarginate labrum; well pronounced, straight, slightly convergent,
supraorbital ridges run backward from the outer base of the clypeus.
Labrum deeply and roundly emarginate. Mandibles stout. Maxillary palpi
extraordinarily stout for a Carabus, the joints being subequal, full and large,
not more than twice as long as broad, together not nearly so long as the
breadth of the head. Labial palpi entirely similar and correspondingly
smaller. Antenne 11-jointed, the second joint a little less than half as
long as the third, the latter apparently cylindrical, the whole antenna rather
short, bemg only about a little more than twice as long as the head, while
it is usually three times as long as the head.

The elytron, which is of just the proper size to match the head, but
which, beg on a different stone, may of course belong to a distinct species,
is placed here because it, too, differs in a similar way from Carabus. It is
not perfect, the base being broken, but it is nearly complete, its original
shape somewhat distorted by flattening, and shows the under surface. Ten
punctate striz are seen, of which the five on the sutural side are much
less crowded than those next the outer margin. Near the middle of the
elytron, on the fifth stria, can be very obscurely seen a pair of fovez of
large size, about as broad as the interspaces, and separated from each other
by more than double that distance. The puncta, seen as slight elevations
in the specimen, are much coarser on the crowded than on the more distant
striz.

Length of head, including mandibles, 5 mm.; of antennze, 8.25 mm.;
breadth of head behind eyes, 3.65 mm.; length of maxillary palpi, 2.65 mm.;
breadth of basal jomt at apex, 0.5 mm.; length of fragment of elytron, 11
mm.; breadth of elytron, 5 mm.

Florissant, Colorado; two specimens, Nos. 4264, 14139.

16 TERTIARY COLEOPTERA OF NORTH AMERICA.

Dedicated to the honored memory of President Thomas Jefferson, one

of the earliest writers on American paleontology.

CALOSOMA Weber.

This genus is at present less numerous in species than the preceding,
but has much the same range. Over twenty-five species are recorded from
North America. The fossil species are, however, more numerous in the
early and middle Tertiaries than are those of Carabus, for no less than
eleven species are described from Aix, Oeningen, Switzerland, and the
Rhine, besides the one from Florissant here recorded.

CaLOSOMA EMMONSII sp. nov.
PL. I, fig. 7.

Represented by an excellently preserved elytron, with subparallel sides
and eighteen strize, of which fourteen are equidistant, equally and gently
impressed, while the others are crowded together next the outer border, and
only distinct on the apical half of the elytron. The interspaces are gently
convex and broken by finely impressed lines into quadrate cells which are
generally about two-thirds as long as broad, and are in all parts very obscure.
The figure on the plate is not magnified enough to show these. No foveze
whatever can be seen. The species is nearest C. willcowi of any of our
native forms and agrees fairly well with it in size and shape; in that species
the fovez are very slight. It agrees still better with the fossil species C.
escheri and C. deplanatum Heer from the Miocene of Oeningen, but both of
these species are very much larger and punctato-striate, while in our species
no sign of punctures appears.

Length of elytron, 13 mm.; breadth, 4.5 mm.

Florissant, Colorado; one specimen, Nos. 20 and 71.

The species is named for my honored instructor, the late Dr. Ebenezer

Emmons.
ELAPHRUS Fabricius.

The present is the only known fossil species of this north temperate
genus, excepting one which has been indicated from Oeningen.

the surface slightly roughened, the color testaceous. It differs from any
Nebria I have seen in that the sutural stria runs uninterruptedly to the base,
while a short, oblique, faint, supplementary stria runs between the first and
second strize into the former near the base.

BEMBIDIUM Latveille.

Of this dominant genus, dominant especially in the north temperate
zone, and of which more than one hundred and twenty species are known in
America, a number have been found fossil. Most of these, including five
existing species and ten in all, are confined to the Pleistocene of France,
Bavaria, Galicia, Ohio, and Canada; the others, seven in number, come
from the middle and lower Tertiaries of Radoboj, Aix, Amber, and Colorado,
while the genus has been recognized also at Oeningen and in Alsatia. The
following species are included in the above enumeration:

slender cylindrical joints; the thorax is unusually quadrate, tapering but
little posteriorly (though this may be only in appearance, through the par-
tially lateral manner of its preservation), with well-rounded angles and
truncate base and apex; there is a slight median impressed line and the
surface is very delicately scabrous, with a slight tendency to a transverse
arrangement of the roughnesses. Elytra uniformly striate throughout, the
strie apparently most delicately and faintly punctulate, though this is
hard to determine, as the specimen is preserved in reverse and the striz
appear as ridges.

Of the same size as the last (5. obductwm), but differing from it mark-
edly in the form and structure of the thorax, which is considerably broader
_than the head, broadest in the middle of the anterior half, and rapidly taper-
ing posteriorly to near the tip, when it tapers less rapidly, being thus sub-
cordate. There is a median impressed line and the surface is longitudinally
and very delicately corrugate in wavy lines. The rest of the body is very
obscurely sculptured, but the elytra are apparently uniformly striate, at
least at base, and distinctly punctate.

PATROBUS Dejean.

This genus has been found fossil only in the Pleistocene. The exist-
ing European species, P. excavatus Payk., has been recognized in France
and Bavaria, and a couple of extinct species have occurred in Galicia and
Canada. The present distribution of the genus is in the boreal portion of
the north temperate zone.

20 TERTIARY COLEOPTERA OF NORTH AMERICA.

MYAS Dejean.

Both the species of Myas here described agree closely together and
differ from the species now belonging to the United States fauna in the
shortness of the antennze, the form of their joints, and the apical elongation
of the hind trochanters, but they agree so closely in all other features,
including the dilatation of the terminal joint of the labial palpi, and so cer-
tainly belong to the Pterostichini by all the available characters, including
the three glabrous basal joints of the antennz, the structure of the mentum,
the quadrisetose ligula, and the elytra without dorsal puncture, that there
can be no doubt they belong either in the nearest neighborhood of Myas
or strictly within that genus. _

No other fossil species of the genus are known. It is a small group,
with only a single European and two North American species.

MyYAS RIGEFACTUS sp. nov.
Pl. I, fig. 4.

A single specimen shows an inferior surface through which the striation
of the elytra can be seen, and is very perfectly preserved. The short and
stout antenne, the enlarged palpi, and the structure of the hind legs appear
to agree better with Myas than with any other genus. The general form of
the body, with the proportions of head, thorax, and abdomen and the exact
shape of the thorax agree perfectly with M. cyanescens Dej. The antenne
differ somewhat; they are 11-jointed, about half as long only as the elytra, the
first joint a little larger than the others, the terminal oval, the remainder
subequal, about half as long again as broad, not very strongly constricted
at the base, and squarely truncate apically. Mandibles, labrum, and palpi,
as well as the prominence of the prosternum, much as in Myas. Hind
coxze attingent at the tip of a broad triangular extension of the abdomen;
hind trochanters very large, nearly two-thirds as long as the femora and
separated from them by an unusually straight suture, the apex pointed.
Faint signs of simple elytral strie seen through the body (not shown in the
figure) indicate a close resemblance to WM. cyanescens.

Length of body, 13 mm.; length of elytra, 7.5 mm; breadth of elytra,
5.2 mm.; length of antenne, 3.5 mm.

Florissant, Colorado; one specimen, No. 9173.

CARABID A. 21

MyYAs UMBRARUM sp. nov.
JOG IG ie, lil,

Several specimens are preserved, but only one is in a condition at all
satisfactory. This is preserved both in obverse and reverse, one showing
best the upper surface (but as a cast), the other the under surface. As the
antennze, legs, and mouth parts are almost all excellently preserved, there
is little left to be desired. The species is a little smaller and stouter than
the living M. cyanescens De}. or the fossil M. rigefactus, just described, and
has comparatively shorter elytra. The antennz are about three-quarters
the length of the elytra, with joints far less moniliform than in the recent
species, the first joint much stouter than the rest, the second quadrate, the
terminal oval, the remainder subequal, nearly twice as long as broad, and
shaped as in the preceding species, but more rounded apically. Laterally
the prothorax is regularly and gently convex and delicately margined, with
a distinct median furrow and very slightly impressed basal impressions.
The elytral striz are not punctured, the first stria is slightly angulate at the
base, and outside, from the extreme base of the second stria, running
obliquely into it and subparallel to its basal course, is a brief supplementary
stria, faintly impressed. The hind tarsal joints are of more nearly uniform
length than in MW. cyanescens and with shorter terminal spines, and the hind
tibiz are not apically dilated to such an extent as in the living species with
which we have compared it. The structure of the hind trochanters is
exactly as in M. rigefactus, from which species it differs in its greater
stoutness, the more obconic forms of the antennal joints, and the more
regularly convex sides of the pronotum.

Length of body, 11.65 mm.; of elytra, 6.75 mm.; breadth of elytra,
4.8 mm.; length of antennze, 4.2 mm.; of hind tibiz, 2.6 mm.

Florissant, Colorado; three specimens, Nos. 503, 8457 and 9208,14138.

PTEROSTICHUS Bonelli.

This is another dominant genus of Carabidze, north temperate in char-
acter, though with some Australasian forms, and of which considerably
more than a hundred species are known: in North America. It has been
found in considerable numbers in Pleistocene deposits, half a dozen recent
species having been recorded from England, Switzerland, and Galicia,

22 TERTIARY COLEOPTERA OF NORTH AMERICA.

while eleven extinct forms are recognized in Germany, Galicia, Pennsyl-
vania, Ohio, and Canada. Besides these, in the older Tertiaries two species
are here described from Florissant, three have been described and two
others indicated from Oeningen, and the genus has been recognized in
amber.

the antenne, and the eyes large but not greatly prominent. The thorax is
somewhat crushed and distorted, but it is apparently broader than long,
with gently rounded sides, the front angles square but not projecting, and
the posterior margin squarely truncate. The elytra have a slight, well-
rounded humeral angle, the strize are deep and simple, and the interstitial
spaces strongly convex; the sutural stria, not shown in the drawing, is of
moderate length and does not appear to unite with the first regular stria in
the figured specimen, but does so plainly in the other. One specimen
shows the whole upper surface of the body excepting the two front pairs
of lees, part of one elytron, and the abdomen; the other a single elytron.

Length of body, 16.5 mm.; of elytra, 9.75 mm.; breadth of one of latter,
3.5 mm.

This species is represented by several specimens showing either the
larger part of the body with elytra (but usually with the abdomen missing),

or simple elytra. It is of about the same size as P. pumpellyi; the head is
smooth with a similar, but sometimes inconspicuous, transverse impressed
line between the antennze; the thorax is squarely truncate anteriorly, with
slightly projecting front angles, sides broadly, rather regularly and some-
what strongly rounded, so that the thorax is as broad posteriorly as ante-
riorly and fully half as broad again as long. Some specimens show a
tendency to subangulate sides, and the slight median impressed line is
scarcely noticeable in any (not given in the figure); the surface is entirely
smooth. The elytra are smooth and flat but for the regular and not deep
strie, which show no punctuation and leave the interstitial spaces without
convexity; there is a moderately long sutural stria connecting with the first
longitudinal stria. .

Length of body, 16 mm.; of elytra, 9 to 9.5 mm.; width of one, 3 to

EVARTHRUS LeConte.

The following is the only known fossil species of this genus, a consid-
erable north temperate group with about a dozen North American species.

EVARTHRUS TENEBRICUS Sp- nov.
Pl. I, fig. 8.

Of this only the head is preserved, but this is so different from any-
thing else which has been found fossil that it merits mention. It is of
about the size of Hvarthrus gravidus Hald., and is placed in this genus on
account of the brevity of the last joint of the labial palpus. The head is
subquadrate, about as long as broad, slightly narrower in front than behind,
with two transverse lines, one in front of and the other behind the antennze,—
the former the transverse impressed line of the upper surface, the latter the
base of the labium seen through the head; the eyes are rather large, but
not at all prominent; the mandibles stout and strongly curved; the maxil-
lary and labial palpi unusually stout, the joints of the former subequal, not
more than twice as long as broad; of the latter, the ultimate very much

shorter than the penultimate, indeed scarcely more than half as long,
squarely truncate. Only about half a dozen joints of the antennz are pre-
served, of which the basal is not more than half as long as in E. gravidus,
while the other joints are as there.

Breadth of head at the eyes, 3.25 mm.

Florissant, Colorado; one specimen, No. 1899.

AMARA Bonelli.

This is a genus numerous in species, mostly confined to the north tem-
perate zone, and of which over sixty are found in North America. Three
existing species have been found in the Pleistocene of Germany and Bavaria,
and two extinct species in that of Galicia. Besides these, two undescribed
species are recognized by Forster in the older Tertiaries of Alsatia, and
three are described by Heer from Oeningen; to these are to be added the
five Florissant species.

The Florissant species referred here differ from existing forms in several
particulars, but I can not find that they agree better with any other types.
They are remarkable for the shortness of the thorax, the breadth of the
head, and the small size and anterior position of the eyes, which are next
the antennz and removed as far as possible from the border of the thorax.

AMARA REVOCATA sp. Nov.
Pl. I, fig. 6.

Agrees well in general appearance, in size, and in form with 4. angustata
Say of the Northern States. It is smooth throughout, the thorax nearly
twice as broad as long, with well-rounded slightly produced front angles,
gently convex lateral margins, and a slight median impressed line. Elytra
smooth, with gently impressed simple strize and flat interstitial spaces.

Length of body, 6.5 mm.; breadth of elytra, 2.4 mm.

Another species, most nearly resembling 4. awrata Dej., but much
smaller, occurs at Florissant. It is the smallest species found there and is
remarkable for its short and broad thorax and the shortness of the antennal

joints. The head is not so broad in proportion to its length as in the other
Florissant species, but on the other hand the thorax is broader, being more
than twice as broad as long and exceptionally broad in front, where the front
angles are not produced forward; the front margin is scarcely concave, the
outer margin gently convex, with the height of the curve rather in advance
of the middle; there is the usual impressed median line. The elytra are no
broader than the thorax, with scarcely rounded humeral angies and _strize
as in the other species.

Length of body, 5 mm.; of antenne, 1.5 mm.; breadth of elytra,
2.25 mm.

Florissant, Colorado; four specimens, Nos. 6226, 6970, 7060, and of
the Princeton collection, No. 1.511.

AMARA VETERATA Sp. NOV.
Pl. Il, fig. 3.

A number of specimens, none of them very completely preserved,
represent a species intermediate in size between A. powelli: and A. dane on
one side and A. revocata and A. sterilis on the other. It has a more regularly
oval shape than A. dane, to which it is on the whole the most nearly allied,
but the form of the head and thorax is almost exactly as there. The elytra
have fuller sides than even in A. powellii, with the humeral angle as in A.
dane. None of the specimens show the elytral strize with sufficient distinct-
ness for characterization, but they are evidently similar to those of the
other species. Excepting in one specimen there is no distinct sign of a
median impressed line on the pronotum, and in this case it is very slight.

AMARA POWELLII sp. Nov.
JEAL, JL, amass 2A),

This species is represented by a number of tolerably good specimens
resembling A. impuncticollis Say in size. The head is unusually broad
for its length, the portion back of the base of the mandibles being fully
half as broad again as long; the eyes are small, placed well forward, and
globular, though not greatly protruding. The prothorax is about twice as

CARABIDZE. Dil

broad as long, with roundly excised anterior margin, truncate posterior
margin, and gently convex lateral margins, the broadest part just in front
of the middle, and the front angles hardly projecting more than required
by the different curves of the front and lateral margins. Surface smooth,
the prothorax with a distinct impressed median line. Elytra with the
humeral angle well rounded off, the strize distinct, but delicate and simple,
the interstitial spaces flat and smooth.

Length of body, 8 mm.; of antenne, 2.5 mm.; width of elytra, 3.2 mm.

Survey when this description was written.

AMARA DAN sp. Nov.
Pl. I, figs. 8, 10, 11.

This largest and most abundant of the Florissant species of Amara
seems most to resemble A. californica Dej., and differs from A. powellii
mainly in its greater slenderness; its head is relatively smaller, and the
greatest width of its thorax appears to be in the middle rather than in front
of it; the elytra have more nearly parallel sides and the humeral angle is
less rounded off. Like it the head is broad and the eyes placed well for-
ward, and not protuberant; the elytral striz are delicately impressed,
the interstitial spaces flat and smooth, and the prothorax has a delicately
impressed median line.

PLATYNUS Bonelli.

This is a dominant cosmopolitan genus, of which nearly ninety species
occur in North America. In Europe only two species have been found

Somewhat nearly allied to P. sinuatus Dej. The antenne are longer
than the head and thorax together, the head as well as the thorax with a
median impressed line. Prothorax nearly half as broad again as the head
(not including the projecting eyes) which is a little narrower than the length
of the prothorax; front and hind margins squarely truncate, the sides
strongly arcuate, subangulate, broadest about the middle, none of the angles
rounded. Elytra with the humeral angle well rounded, the surface flat and

genus is rather poorly represented in the United States, but is cosmopolitan
in nature.

GALERITA MARSHII sp. nov.

Pl. II, fig. 5.

A pair of elytra in place are to be referred here. The texture was
evidently not dense, the elytra with straight, scarcely convex sides, apically
truncate, but a little rounded and obtusely angled. A very little only of
the base is lost, showing the species to be a small one and the combined
elytra about half as long again as broad. The strie are delicate, very
slightly impressed, but sharp and straight, minutely and not closely pune-
tured; the interstitial spaces are also more coarsely and densely but faintly
punctured, the general punctuation being more obvious than the striation.

which has but few species, occurring in most parts of the world, only four
of which inhabit the United States.

PLOCHIONUS LESQUEREUXI sp. Nov.
Pl. IIL, fig. 2.

A single specimen and its reverse seem to fall in this group, and to be
not distantly related to P. timidus Hald., though it is impossible to say that
it is not a Pinacodera. The antennz are about two-thirds as long as the
elytra, with rather uniform joints about twice as long as broad and nearly
cylindrical, the base being only a little smaller than the apex. The pro-
thorax is about half as broad again as long, or half as broad again as the
head, apart from the rather prominent eyes ; with rounded sides, broadest a
little behind the middle, but not greatly enlarging behind the broad, squarely
truncate apex with nearly rectangular lateral angles; the surface appears to
be smooth, with an impressed median longitudinal line. Elytra posteriorly
truncate, distinctly striate, as in the Lebiini, the interspaces flat, with no
sign of punctuation here or in the striz, but with a feeble sign of trans-
verse wrinkling, as is seen, but more heavily, on the thorax of P. temidus.

CYMINDIS Latreille.

Two species of this genus occur in the Pleistocene of the New World—
in Canada and Massachusetts—while in Europe two other species occur in
the older Tertiaries of amber and of Oeningen. At the present time the
genus is tolerably rich in species and is found mostly in north temperate
regions, and North America has its fair share.

This species comes in the vicinity of B. alternans Dej., but is somewhat
smaller, with shorter legs. Excepting in one specimen, which shows the
middle and hind legs in addition, only elytra are preserved. The legs are
slender, the tibize rather sparsely haired and armed at tip with rather short

A species allied to B. fumans Fabr., with which it agrees in size, the
clothing of the elytra and the character of the striz. It is represented by
a single elytron much broader than in B. newberryi and in which the
humeral angle is more pronounced; the apical margin is decidedly truncate
and the elytron is furnished with tolerably coarse ridges, interrupted so as
to give them a bead-like appearance, or a chain of slightly elongated
tubercles; the interspaces are flat and scantily clothed with tolerably long
delicate hairs.

Length of elytron, 6 mm.; breadth, 3.2 mm.

DY TISCID 44.

The only fossils of this family in North America are two species in the
Pleistocene of Massachusetts and two in the older Tertiaries of Colorado,
each of the four belonging to a distinct genus. In the Old World, fifty-six
species have been found, belonging to seventeen genera, only two of them
represented among the American fossils, and these the older. Of these
species, twenty-seven, representing eleven genera, belong to the older
Tertiaries, and twenty-nine species of nine genera to the Pleistocene. Of
the Pleistocene species ten are recognized as still living.

AGABUS Leach.

A richly endowed cosmopolitan genus, of which nearly fifty species are

Two existing species have been credited to the Pleistocene of England and
five described from that of Galicia.

AGABUS RATHBUNI sp. Nov.
PL. IV, fig. 4.

The structure of the under surface of this beetle, as shown in the
figure, leaves no doubt of its belonging to the dytiscid tribe Colymbetini,
and the form of the lateral wing of the metasternum with the carinate pro-
notum refers it to Agabus. Naturally there is little on the under surface to
distinguish species in a group so abundant in forms as Agabus, but it may
be said that it has a broadly ovate form, approaching the shape of the
Gyrinide in its posterior breadth and narrowing anterior portions; the
hind legs are rather stout, though not large, and the hind coxee and anterior
half (at least) of the abdomen are very distantly, arcuately, and exceed-
ingly finely striate.

genera are referred to living forms; these last are all from Pleistocene
deposits in Europe, which have also yielded seven extinct species of four
genera, besides which two species of different genera have been found in
America. To the older Tertiaries belong forty-five species of ten genera
in Europe and fourteen species of eight genera in America, the same
genera being represented on both continents in three cases if only the older
fossils are considered, in five cases if all are taken into account. Three of
the European genera from the older formations are regarded as extinct.

HELOPHORUS Fabricius.

A tolerably prolific genus, mainly north temperate in distribution, with
about a dozen North American species. Five extinct species have been
found in Pleistocene deposits in Galicia and Ohio, and two in the older
Tertiaries of Baden.

HELOPHORUS RIGESCENS.

Clay beds near Cleveland, Ohio.

HYDROCHUS Leach.

A dozen species of this genus exist in North America, being nearly half
the known species, the others occurring in the north temperate regions of the
Old World. The only fossil species known are the two here recorded, one
each from the Pleistocene of Ohio and the Oligocene of Wyoming.

HY DROPHILIDZ. 39

TROPISTERNUS Solier.

This is an American genus, of which nearly half the species (about a
dozen) occur in the United States. Four fossil species are known from the
early Tertiaries of Wyoming and Colorado.

TROPISTERNUS VANUS sp. NOV.
PI. V, fig. 1.

The specimen referred here apparently belongs to this genus, although
the scutellum is of a somewhat smaller size than is characteristic of this
genus and the sculpturing of the elytra is unusual. The length of the
abdomen is doubtless due to accident, the character of the elytral tips
indicating that they embraced its extremity. The form of the body and,
with the above accidental exception, its several regions correspond closely
to Tropisternus, though by the flattening of the head, which brings the
labrum (not separately indicated in the figure) upon the same plane, the
head is made to have an abnormal length. The eyes are large but scarcely
protrude beyond the general curve of the side of the head. The prothorax
shows a delicate margination laterally and exceedingly delicate wavy striate
markings, as if longitudinally combed, hardly obser vable under an ordinary
lens, instead of the minute punctuation usually found in ‘Tropisternus.
There is also observable along the middle line on the posterior half of the
pronotum and the anterior part of the abdomen a slight cariation, which is
probably the impression of the sternal carina characteristic of this group of

Hydrophilidee. The elytra are rather short, their outer edge very delicately

marginate, the surface with the same sculpturing as the prothorax, and
besides very faintly and very narrowly striate with longitudinal punctures,
or more properly striz. These are about as distinct as in 7” striolatus LeC.,
but are wholly different on account of their extreme slenderness and the
longitudinal character of their components.

Length of body as preserved, 9.25 mm.; length to Hp of elytra, 8.1 mm.;
breadth, 4mm.; length of elytra, 4.6 mm.

Florissant, Colorado; one specimen, No. 9210.

TROPISTERNUS LIMITATUS Sp. noy.
Pl. V, fig. 2.

Although this species is placed in this genus, it is only temporarily,
until better and more abundant material shall give the opportunity of
properly characterizing the genus to which it really should be referred,
which, so far as we know, is extinct. It belongs without doubt to the
Hydrophilini, as its wide prothorax and compressed tarsi show, but as the
genera of Hydrophilide are tolerably constant in size and this is very
much smaller than any Hydrophilini known, it can hardly be doubted that
it will prove a distinct generic type; moreover the structure of the hind
tarsi is very different from what we find in the other genera; for though
strongly compressed, they are subequal, somewhat ovate, and two or three
times as long as broad. The whole insect is of a very regularly elongate
oval shape, of a uniform carbonaceous color, showing no sculpture what-
ever beyond a pair of straight raised lines, converging posteriorly, which
cross the prothorax and thus limit a wedge-shaped median piece, the front
margin of which is rather more than one-third of the front border of the
prothorax, while the hind margin is about one-third its anterior width. It
is probable, however, that these raised lines are indications of some sculp-
tural characteristics of the under surface, as they are not quite symmetrical
and do not appear on both specimens referred to this species. The eyes
are large, subglobose, extend slightly beyond the curve of the head, and,
as viewed from above, are longer than broad. The sutural edge of the
elytra is very delicately margined.

Length, 5 mm.; breadth, 2.6 mm.

HYDROPHILITES Heer.

The generic name is given by Heer to the following fossil species,
allied to Hydrophilus. No-other species is known.

Naujat, Greenland.
HYDROCHARIS Latreille.

A widespread but rather limited genus, three species of which occur
in the United States. The species from Colorado here described is the only
one known in a fossil state.

HyprRocHARIS EXTRICATUS sp. nov.

Pl. V. fig. 4.

The single specimen referred here is slenderer and smaller than any of
our existing species, and further differs in the great size of the eyes, which
are transverse and separated by less than double their own width, and the
excessive length of the terminal spines of the hind tibize, both of which are
nearly half the length of the tibie. Being preserved on a ventral aspect
any punctuation of the elytra is invisible. ‘The sternal carina appears to
be very slender and to extend beyond the hind cox to a length rather
more approaching its character in Hydrophilus, though it certainly does not
extend beyond the second abdominal segment, and the prosternum appears
to be equally carinate with the hinder parts of the thorax.

Length, 18 mm.; breadth, 6 mm.

LACCOBIUS Erichson.

A limited genus of about a dozen species, almost exclusively confined
to the north temperate zone and of which only two species are known in
the United States. A single fossil species is found in the Pleistocene of
Galicia, three others in the older Tertiaries of France and the Rhine, and
one in Wyoming.

HYDROBIUS Leach.

A cosmopolitan genus with numerous species, of which nearly half
come from North America. A couple of existing species have been found
in the Pleistocene of Bavaria and Galicia; and in the older Tertiaries ten
extinct species occur at Oeningen, Radoboj, Aix, Spitzbergen, Florissant,
and in Wyoming.

HyYDROBIUS MACERATUS sp. Noy.
Pl. V, fig. 3.

The specimen which is referred here seems to be more nearly related
to the smaller forms of Hydrobius than to anything else, though it evidently
belongs to a distinct genus on account of the extreme breadth of the pro-
sternum, the front and middle cox being thereby closely crowded together.
The slenderness and cylindrical character of the hinder tarsi show that it
belongs in this neighborhood, but the imperfect preservation of the single
specimen known leaves much to be desired. The legs are rather slender,
though the femora are moderately stout, the tibiee are considerably longer
than the femora, while the very slender tarsi are much shorter and the
hinder pair are 5-jointed, the last two joints being equal and longer than
the others. There is no sign of any transverse carina in front of the middle
cox. The insect is of an elongated oval form, with a tolerably large head
and an unusually large prothorax, which is much more than half as long as
broad. The under surface, and noticeably the prosternum, is faintly, dis-
tantly, and rather coarsely punctulate.

Length, 3.1 mm.; breadth, 1.3 mm.

CERCYON Leach.

A cosmopolitan genus, very rich in species, mostly occurring in the
north temperate regions and abundant in the United States. Only a couple
of fossil species are known, an undetermined species from the Pleistocene
of Bavaria, and a species from the older Tertiaries of British Columbia.

SILLPHID 4.

Fossil Silphide are uncommon. Sixteen species in all are known,
belonging to eight genera, Silpha alone being represented by more than one
species. All of these species except four of Silpha are found in the older
Tertiaries. Only two genera with a single species each have occurred in
America, and of these one, Silpha, occurs also in the Old World Tertiaries.
Of the Old World genera four are recognized in amber only, and of the
three from the rocks one is regarded as extinct.

SILPHA Linné.

We have in the United States about ten species of this genus, which is
mainly north temperate and rich in species. Two recent species have been
recognized in the Pleistocene of Bavaria and England, and two extinct
species in Galicia. In the older Tertiaries five species occur, one each in
the deposits of Spitzbergen, Radoboj, Oeningen, the Rhine, and Colorado.

SILPHA COLORATA sp. lov.
Pl. V, fig. 5.

The only specimen known is broken just behind the base of the elytra
and all the portion in front of it lost. What remains, however, is so charac-
teristic that there can be little doubt that it belongs in this family and prob-
ably to Silpha. It has the aspect, however, of a Necrophorus from the spots

and hairiness of the elytra, but their non-truncate character and the apical
slenderness of the hind tibiae show that it can not be referred to that genus.
The elytra are long and narrow, without longitudinal carinze, with tapering
pointed apices, sparsely covered with rather long hairs, visible only on the
pale transverse bands which cross the base and middle of the apical half of
the elytra; these have rounded outlines, apparently just fail to reach either
margin, and are more than half as long as broad on each elytron; the abdo-
men is hairy and angulate at tip, the hind tibiz slender and equal, with
rather dense and coarse erect hairs and apparently without apical spurs.
The hind tarsi are also hairy but less prominently, the first joint long, all
the remainder short and equal, the last not seen in the specimen.

Length of fragment, 6 mm.; of elytron, 5 mm.; breadth of same, 1.5
mm.; probable full length of elytron, 6 mm; probable length of beetle, 11
mm.; length of hind tibize, 2.5 mm.

AGYRTES Frohlich.

genus, which has now a very limited number of species in the north tem-
perate zone, and only one in the United States.

AGYRTES PRIMOTICUS sp. Novy.
Pl. V, fig. 6.

The specimen referred here is considerably larger than our native
species and by no means of so slender a form, but it would seem to fall
here from the structure of the antennze and elytra and can not be referred
to any other of our genera of Silphidz. The specimen is tolerably perfect
on the right half of the body, but does not show any important part of the
legs. The head is transversely. oval, smooth, with tolerably large round
eyes. The antenne reach to the base of the elytra; the third joint, though
twice as long as the second, is not longer than the succeeding, though much
slenderer than they and equal, while the next five, though submoniliform,
are larger apically than basally, increase very slightly in size, and the last
three are scarcely larger, equal, and subquadrate, the last apically rounded.

very faintly and delicately punctate. Middle tibize slender and equal, much
smaller than the apex of the femora. Elytra together but little longer than

face delicately, not very deeply, striate, with regular very elongate impres-
sions; interstitial spaces apparently sericeous.

STA PHY LINID 4.

One hundred and thirteen fossil species of Staphylinidze are known or
indicated, sixty-five from the Old World, forty-eight from the New. These
are almost entirely from the older Tertiaries, only seven species, all extinct,
being known from the Pleistocene, two from Europe, five from America;
besides these a number of other forms from the Canadian Pleistocene still
await study.’ These fossil species have been referred to forty-two genera,
of which four are regarded as extinct, three in the Old World, one in the
New. ‘Twenty-five of these genera are found in America, twenty-nine in
the Old World, twelve occurring in both. Only two genera, one on each
continent, have been found in the Pleistocene and not in the older Tertiaries.

One of the peculiarities of the Florissant Staphylinidz as compared
with living forms is the prevalence of species with short antenne. This is
most marked in cases where the species, living and extinct, of the same
genus are compared, and being nearly universal can hardly be referred to
their being in some cases only partially exposed in the fossils, since in very
many all the joints can be seen, and the peculiarity still holds true. The
same thing is true in perhaps equal degree with the legs, which in the fossil
species are almost invariably shorter than in their modern representatives.

HOMALOTA Mannerheim.

This dominant genus is mainly north temperate and numerous species
occur in the United States. The species here recorded is the only one
known as fossil.

ACYLOPHORUS IMMOTUS sp. NOV.
JA MWe alex Go

A rather small species, allied to A. flavicollis Sachse, but differing from
any of the living species I have seen in the brevity of the antenne. The
head is small, well rounded, considerably narrower than the prothorax.
The antennz are poorly preserved, especially at base, and the joints in the
apical half are quadrate, scarcely so long as broad, and only very slightly
enlarged apically, the whole scarcely reaching to the apex of the rather
short prothorax. The latter is scarcely so long as broad, tapers though
very slightly from the base, is truncate at both extremities and smooth; a
pair of punctures are seen on the disk, just where they occur in A. flavi-
collis. Both the prothorax and the head, as well as the finely haired legs,
are of a testaceous tint, while the rest of the body is piceous. The elytra
are obscurely preserved, but are black, hairy, about as long as the prothorax
and a little broader, the whole body enlarging from in front to the tip of the
elytra and then tapering gradually and regularly to the narrowed and

HETEROTHOPS Stephens.

A small genus, most of whose species are found in the north temperate
regions of the Old World, but four or five in North America. A single
species has been found fossil in Colorado. —

HETEROTHOPS CONTICENS sp. Nov.
Pl. V, figs. 8, 9.

A single specimen is referred here with some doubt, as it is not very
well preserved, but it seems to bear a closer resemblance to the species of
this genus than to any other. It is the smallest of the Florissant Staphy-
linidee unless the shorter but stouter Platystethus archetypus be looked upon
as smaller. It is very compact, is broadest at the elytra, narrows rapidly in
front and less rapidly behind, so as to be somewhat fusiform, the extremity
of the abdomen bluntly rounded. The head is short, subtriangular, and
rounded, the antenn (fig. 9) closely resemble those of H. pusio LeC.,
excepting that the last joint is only a little longer and considerably larger
than the penultimate, instead of bemg twice as long and scarcely any
broader; they scarcely reach the posterior border of the pronotum. The
latter is smooth, considerably broader than long, tapers anteriorly a good
deal, but its surface is too broken to show what punctures are present.
The elytra are hairy, as are the sides of the abdomen, and the whole body
is of a nearly uniform very dark castaneous. '

A genus with numerous species, widespread in both worlds. The
older Tertiaries possess five species, two each at Aix and Florissant, and

one in amber.

STAPHYLINID &. 49

The two species here recorded from Colorado differ considerably from
each other in general appearance, but appear to be structurally similar.
They differ from modern species, one more markedly than the other, in the
great brevity of the antennze and of their separate joints, as well as, so far
as can be seen, in the shortness and stoutness of the legs.

LAASBIUM gen. nov. (Aaas, 626@).

This name is proposed for a couple of fossil insects bearing a very close
resemblance to Lathrobium, both in general appearance and in many details
of structure, but which can not be placed there or even in the tribe
Peederini, to which Lathrobium belongs, on account of the entire absence
of any constricted neck, the head being altogether sessile upon and indeed
partially embraced by the thorax. The body is long and slender. The
head is more or less triangular, largest at base; the antennz long, slender,
filiform, all the joints twice or more than twice as long as broad, the first
longer but not much larger, the last shorter and smaller than the rest.
Thorax transverse, equal, with rounded angles. Elytra twice or more than
twice as long as the thorax, and together broader than it. Legs rather short
and slight, but with dilated femora, the fore tarsi apparently not expanded.
Abdomen beyond the elytra as long as the rest of the body with parallel
sides and a bluntly rounded tip.

reaching back nearly to the middle of the elytra, most of the joints anout
two and a half times longer than broad, slightly larger at tip than at base,
rounded. Thorax about a fourth broader than long, a little broader than
the head, with gently convex sides and base, and all the angles similarly
and slightly rounded, the surface smooth and apparently, like the head,
without hairs. Legs not very long, the femora considerably dilated, the
tibiee slender but slightly enlarged at the tip, the tarsi very slender. Elytra
slightly longer than the head and thorax together, considerably broader
than the thorax, smooth, with long and very distant delicate hairs. Abdomen
scarcely broader than the thorax, beyond the tips of the elytra longer than
the rest of the body together, smooth.

LAASBIUM SECTILE sp. nov.
Pl. VI, fig. 3.

This is a much stouter form than the last, and not so elongated, but in
all its essential features it agrees so well that it should fall in the same
genus; the short head and thorax, the long antennz and tegmina, with the
elongated joints of the former, mark it as allied. There is but a single
specimen and that not very distinctly preserved. The head is shorter than
broad, subtriangular, with rounded sides, and apparently smooth surface.
The antennze are imperfectly preserved, but are at least as long as the head
and thorax together, and probably longer, very slender, with joimts which
beyond. the basal joint and before the middle are about three times as long
as broad and nearly twice as broad apically as basally. Thorax apparently
almost twice as broad as long, broader certainly than the head, broadest
apparently just behind the head, with rounded sides, and the surface smooth,
with a few scattered hairs. Legs slender and apparently proportionally
longer than in L. agassizii. Elytra longer than the head and thorax together,
and broader than the thorax, smooth and at most with but a few scattered
hairs. Abdomen broader than the thorax but narrower than the elytra,
beyond which it is scarcely so long as the rest of the body, equal or

STAPHYLINUS Linné.

This genus has numerous species all over the world, of which about
twenty occur in the United States. Fossil species are by no means unknown,
nine having been described from Aix, Oeningen, and Florissant, while the
genus has been recognized in such different deposits as Senigaglia in Italy,
Sicilian amber, Baltic amber, Rott on the Rhine, and the Isle of Wight,
leading us to presume several additional species, all in the early Tertiaries.

STAPHYLINUS LESLEYI Sp. nov.
Pl. VI, figs. 6, 7.

This most abundant species of the genus and one of the commonest of
the family at Florissant resembles most S. cinnamopterus Grav., but is scarcely
so large and has shorter and stouter antenne, and slenderer less densely
spinous tibie. The head is subtriangular, the basal third with parallel sides,
in front of which it tapers considerably; the posterior margin is truncate,
but with rounded angles, and the head is a little longer than broad, includ-
ing the sharply pointed longitudinally channeled mandibles; the surface is
very delicately granulate. The antennz are about as long as the elytra
and are well represented in fig. 7, though the extreme base of the first joint
does not appear. The pronotum is slightly broader than the head and of
the same length as it, fig. 6 showing it a little too short; it is nearly quad-
rate, of about equal length and breadth, with slightly convex sides and

rounded angles, especially posteriorly; the surface appears to be much as
in the head and delicately and briefly villous. The elytra are together
rather broader than long and somewhat broader than the pronotum, with
which they agree in texture and clothing. The legs are not very long but
very slender, the femora delicately incrassate, the tibiz enlarging regularly
so as to be half as large again at tip as at base, with recumbent not very
heavy spinous hairs and delicate apical spurs. Abdomen and abdominal
appendages much as in S. cimnamopterus.

STAPHYLINUS VETULUS Sp. nov.
Pl. VI, figs. 11, 12.

A large and stout species, perhaps as nearly allied to our common S.
vulpinus Nordm. as to any of our living forms. The head, however, is more
nearly rotund, not truncate posteriorly, and the sides strongly convex;
apparently the surface was somewhat similarly punctate and was covered
with a similar pile; the only bristles which can be seen are a pair of slender
straight ones, distant from each other, but not so distant as they are from
the eyes, between which they are placed; they are about as far apart as
those on the front margin of S. vulpinus, but as far back as those on the
inner margin of the eyes; they are also shorter than any of those on the
head of S. vulpinus; and besides them are indistinct signs of some corre-
sponding nearly in position to those on the front margin and on the posterior
outer angles of S. vulpinus. I have examined nearly all our species of
Staphylinus without finding any trace of bristles in such a position. The
antennz are only partially preserved, the apex of the first joint with the
seven succeeding showing upon one side and scarcely differing from their
structure in S. vulpinus unless the first joint, only the tip of which is seen,
is, to judge from the position of the apex, a little shorter than usual.

much the same size and shape, being subrotund, no longer than broad, with

the front angles well rounded and the sides slightly and roundly angulate
just in front of the middle; it is of the same width as the head, or perhaps
slightly narrower, and shows the faintest sign possible of a longitudinal
median angulation. The elytra are considerably broader than the thorax,
narrowed and rounded in passing forward toward the humeral angle, have
apparently the same surface structure as the thorax, and are about as long
as broad. The abdomen is very regularly elongate obovate, the sides
being nowhere quite parallel but slightly rounded and the narrowed tip
with a regular ovate outline. The remaims of the legs show them to have
been similar in length and stoutness to those of the species mentioned.

STAPHYLINUS sp.

Another species occurs at Florissant, apparently belonging here or to
Ocypus, and of about the size of O. ater Grav. It has a somewhat similarly
shaped head and thorax, which are smooth and glabrous, or nearly so, but
the only specimen obtained (No. 11751) is so badly broken that it can not
be further described.

PHILONTHUS Curtis.

A dominant cosmopolitan genus, of which eighty or nmety species are
already known in the United States and Canada. Including those here
given, seven fossil species have been described from the earlier Tertiary
deposits of Colorado, France, and the Rhine, and the genus has also been
recognized in amber. A single species has been found in the Pleistocene
of Bavaria.

The species which we have here grouped under this generic name agree
in certain characteristics by which they differ from modern species of this
genus. This is particularly the case in the nearly equal width of the head
and prothorax, the brevity and rather uniform breadth of the latter, and the
shortness of the antennez. It is probable that if we could become better
acquainted with their entire structure we should be forced to separate them
as a distinct generic type.

PHILONTHUS MARCIDULUS Sp. NOV.
Pl. V1, figs. 5, 8, 185 14.

A large species, broadest at or beyond the tips of the elytra, the abdo-
men tapering considerably beyond the middle. It was apparently black,
or the abdomen possibly mahogany-black. The head is large, subquad-
rate, apparently of about equal length and breadth, with slightiy rounded
posterior angles and a slight neck; it is largest at or behind the middle, the
eyes similar to but a little larger than those of P. cyanipennis Fabr., which
it seems most to resemble, and the surface is smooth and glistening, with a
few scattered, long, fine bristles; the mandibles are long and finely pointed,
but much stouter and somewhat shorter than in P. cyanipennis; the antennze
reach back only to or slightly beyond the middle of the prothorax, being
considerably shorter than in most modern Philonthi, the brevity resulting
from the lesser length of the elongated basal joints, and especially from the
shorter basal joint, which appears to be scarcely more than half its usual
length in recent Philonthi; the apical joints do not differ. The prothorax
is subquadrate but broader than long, broadest posteriorly, with rounded
sides, well-rounded posterior angles and roundly angulated anterior angles,
the surface smooth and with no clearly perceptible punctures, though these
may have existed. The legs are precisely similar to those of P. cyanipennis
in form and clothing, particularly the armature of the tibize, but are some-
what shorter in proportion, the hind legs, for instance, beg considerably
less than half as long as the body, while in P. cyantpennis they are consider-
ably more than half as long. The elytra are a third longer than the pro-
thorax, rather minutely and obscurely punctate and villous, margined at the
suture. The wings, one of which is pretty well exposed in one of the speci-
mens (see fig. 5), reach to the last segment of the abdomen, are of a smoother
outline than is figured for Philonthus by Burmeister,’ and are of precisely
similar general character, the space between the mediastinal and scapular
veins being delicately corneous, but the thickened recurved vein connect-
ing the upper branch of the externomedian with the scapular, beyond the
joint, is more distinctly a vein in the fossil and completely unites these two
veins, springing as it does distinetly from the externomedian. The two
branches of the externomedian unite at the same point in each, but in the

present (fossil) species at a much slighter angle, while the branches them-
selves are both firm, gently and regularly curving lines, without the sinu-
osity figured by Burmeister; the lower is accompanied throughout its course
by an almost equally distinct vein-like thickening (apparently a fold of the
membrane) given by Burmeister only near the margin of the wing; the sub-
sequent nervules can not clearly be made out. The abdomen is compara-
tively slender, shaped much as in P. cyanipennis, thinly villous, the terminal
lateral appendages nearly as long as the last segment, slender, tapeting on
the apical third but bluntly rounded at tip, clothed rather sparsely with long
and slender bristles; the median appendage of the male by no means as in
P. cyanipennis, but very large and subtriangular, nearly as broad at base as
the apex of the last segment, with convex lateral margin and appearing like
a segment (as it really is) rather than as an appendage, which it resembles
in the same sex of P. cyanipennis, where it is lanceolate with concave sides.

PHILONTHUS INVELATUS Sp. nov.
Pl. VI, figs. 9, 10.

Head subquadrate, broader than long, tapering rapidly behind the eyes
to a somewhat constricted neck, the surface apparently smooth; the eyes
rather large, not prominent, the mandibles as in P. marcidulus or rather
stouter; the antenne not reaching beyond the middle of the thorax and
not very stout, the three basal joints of nearly equal length and twice as
long as broad, the fourth and fifth obpyriform, a little longer than broad,
the apical ones broader than long. Prothorax apparently about equally
broad and long, tumid and largest in the middle, smooth, with a few scattered
long bristles. Legs as in P. marcidulus, but the tibiz rather stouter and
very heavily spined. Elytra about as long as the prothorax and villous.
Abdomen rather slender, equal except the last two segments, with long,
straight, slender, lateral, spinous hairs; last two segments tapering rapidly
to a rather pointed tip; lateral anal appendages long and slender, gently
tapering and blunt tipped. The body is generally black or nearly so, but

the thorax and legs are much lighter and apparently were of a testaceous
color. ;
It appears to be somewhat nearly allied to the modern P. @neus Rossi,
which it nearly approaches in size and with which it agrees tolerably well
in the relation of the second and third antennal joints to the succeeding, but
the posterior angles of the head are less prominent, and like the other species
here described, it differs markedly in the brevity of the antennae. It is
perhaps more closely allied to P. tachiniformis Say, figured by Sharp in
the Biologia centrali-americana, but differs in the same points. In the
shape of the head it is more like P. godmani Sharp from Mexico, but it has
not so long a prothorax.

PHILONTHUS HORNI sp. nov.

Head subquadrate, slightly narrower than the prothorax, but broadest
at base and tapering forward, a little broader than long, smooth. Antennze
scarcely reaching to the middle of the prothorax, moderately slender,
increasing but very little and very gradually in size, the first joint obovate,
largest just beyond the middle and about three times as long as broad, the
second joint much slenderer and about half as long, the third slender and
not greatly shorter than the first, the fourth quadrate, and the remainder
increasingly broader than long, excepting the last, which is ovate. Pro-
thorax broader than the head and nearly half as broad again as long, as
broad anteriorly as posteriorly, with rather strongly and regularly convex
sides, the surface smooth, with scattered short and very fine hairs. Elytra
a little broader and considerably longer than (half as long again as) the
prothorax, villous, with rather short hairs. Legs apparently much as in the
other Florissant species, but only imperfectly preserved. Abdomen sub-
fusiform, largest at the third segment, tapering apically to a not very blunt
point, the surface covered with hairs exactly like the elytra, with straight
lateral diverging bristles on the last two segments. Lateral terminal
appendages nearly as long as the last segment, straight, scarcely tapering,
bluntly rounded at tip and covered with bristles; median anal appendage

lanceolate, half as broad at base as the tip of the last segment, bluntly
pointed, reaching as far as the lateral appendages, and similarly hirsute.

I can find no modern species with which to compare this unless it be
the much slenderer P. tachiniformis (Say), and even in this the prothorax is
much longer.

prothorax, 1.2 mm.; breadth of same, 1.8 mm.

PHILONTHUS ABAVUS sp. Novy.
Pl. VI, fig. 3.

This species is represented by several specimens, but none that are well
preserved. It is smaller than the others described and differs from them in
some few particulars, which can be determined. The head is rather small,
narrower than the prothorax, subquadrate and smooth, not narrowed poste-
riorly; the joints of the apical half of the antennz are entirely similar to
those of P. horni. The prothorax is broad and short, as in P. horni, broad-
est, however, posteriorly and narrowing throughout, as ordinarily in modern
species of this genus, smooth. The legs are as in P. marcidulus, but the
tibiee are less heavily spined. The elytra are twice as long as the prothorax,
thinly and very delicately villous, slightly marginate at the suture. The
abdomen tapers gradually from the tip of the elytra to a bluntly rounded
apex and is sparsely villous.

XNANTHOLINUS TENEBRARIUS sp. nov.
Pl. VI, figs. 4-6.

The specimen referred here, if it does not belong strictly to Xantho-
linus, is certainly nearly allied to it, but it differs from the modern species
we have seen, either in nature or in illustrations, in the brevity of the antennee
and their apical slenderness. It seems to be nearly allied to X. emmesus
Gray., but is of the size of X. rudis Sharp of Guatemala. The head is
quadrate, longer than broad, narrowing posteriorly to a short neck half as
broad as the head; antenne scarcely longer than the head and neck, the
first joint long, about one-fourth the length of the whole antenna, enlarg-
ing apically to nearly double the width of the succeeding segments, the
second and third of which are quadrate, the remainder transversely obovate,
the terminal subglobular. Thorax as long as the head, apparently narrower
than it, and as seen from a partially side view, it appears to taper forward;
it is apparently smooth. The legs are similar to those of X. emmesus, but
are proportionally a little shorter, and the tibize are of perhaps more uni-
form size. The elytra are considerably longer and somewhat broader than
the prothorax and apparently smooth. The abdomen is narrower than the
elytra, slender, elongated, with parallel sides, a little enlarged at the fifth
joint, tapermg beyond to a rounded extremity, the joints smooth, excepting
the last, which bears some bristly hairs toward tip.

LEPTACINUS Erichson.

North America possesses about a dozen species of this genus, and about
as many more are scattered all over the globe. The only fossils known are |
the five here described from Colorado.

The species we have placed here belong without doubt to the Xantho-
lini, but excepting the first and perhaps the second, do not agree with any
of the genera of our existing fauna, being remarkable for the shortness of
the head, antennze, and thorax, and the relative brevity of the elytra; the
sutural stria is slight and the thoracic punctures do not appear to be
aligned; nevertheless, as in the brevity of the parts they share the common

STAPHYLINID. 59

characteristics of most of the Florissant Staphylinidee, it has seemed best
to refer them to Leptacinus, with which group they appear best to agree.

LEPTACINUS RIGATUS sp. NOV.
Pl. VI, fig. 11.

Head elongate-oval, considerably longer than broad, the sides only
slightly convex, the hind angles well rounded, the eyes anterior, small, and
scarcely prominent, the surface smooth but very faintly and very sparsely
pilose, with three tolerably distinct longitudinal carinze, one median and
two postantennal, disappearing before the hind margin; similar but very
brief postantennal carinze are seen in a species of Leptacinus marked
doubtfully in Mr. Austin’s collection as L. batychrus GyllL., with which, better
than any other I have seen, this species agrees generally. Antenne reaching
to the middle of the thorax, moderately stout, scarcely increasing in size
apically, the basal joint fully three times as long as broad, rather stout, the
second less than half as long, and only half as long again as broad, the
rest scarcely broader than long, with rounded sides. Thorax slightly longer
than the head, oval, with well-rounded sides and ends, scarcely broader in
front than behind, the surface sparsely punctate, the puncta giving rise
each to a rather short hair. Elytra scarcely longer and much broader than
the thorax, apically truncate, with the same punctuation and clothing as the
thorax. Abdomen about a third as long again as the rest of the body and
slender, being at base no broader than the thorax, with nearly parallel
sides, but enlarging very slightly to the fifth segment, afterwards narrowing
slightly, the tip rounded; the surface is more sparsely punctate than the
thorax and elytra, with similar but seemingly shorter hairs, apparently with-
out sete or fringes to the joints.

a slight and narrow neck, the surface smooth, with a few short and deli-
cate scattered hairs. Antenne about as long as the head and neck, the
joints beyond the first nearly quadrate, scarcely if at all enlarging apically.
Thorax scarcely longer than and of the same breadth as the head, appar-
ently larger apically than at base, smooth, with a few short and delicate
scattered hairs. Legs rather short. Elytra a little longer and somewhat
broader than the thorax, apically squarely truncate, with a slight sutural
stria, more distinct basally, and very sparsely pilose. Abdomen rather
slender, equal, with a bluntly rounded tip, smooth, with a few scattered
hairs.

Length, 5.1 mm. The specimen is preserved on a side view, so that
the breadth can not be accurately given, but assuming that of the abdomen
to be the same as the height, the breadth behind the elytra is 0.85 mm.

Florissant, Colorado; one specimen, No. 265.

LEPTACINUS MACLUREI sp. noy.
Pl. VI, figs. 7, 15.

Head half as long again as broad, parallel sided posteriorly, tapering

surface smooth, with scattered hairs on minute tubercules. Antenne only
a little longer than the head ard neck, the first jot nearly a fourth of the
total length, the second to the fifth joints longer than broad, the sixth quad-
rate, the remainder broader than long, the whole antenna enlarging very
slightly and very gradually toward the tip, and the apical joint subglobose.
Thorax slightly broader and a little shorter than the head, quadrangular,
with equal sides, smooth, and clothed like the head. The legs agree very
well with modern Leptacini and are not apparently any shorter. Elytra
broader and longer than the thorax, thinly clad with short hairs. Abdomen
very slender, but apparently enlarging a little toward the fifth segment and
then tapering to a rounded point, the segments sparsely clothed with deli-
cate hairs.

LEpracinus LEIDYI Sp. nov.
Pl. VU, fig. 14.

Head half as long again as broad, tumid, with convex sides, rapidly
tapering behind to a distinct neck, a little more than half as wide as the
head; surface coarsely and somewhat sparsely punctate. Antenne reaching
back scarcely beyond the front edge of the prothorax, scarcely enlarging
apically, the joints beyond the basal one subquadrate, the second to the
sixth inclusive slightly longer than broad, those beyond slightly broader
than long, the last subglobose. Thorax about as long as and a little broader
than the head, the sides apparently parallel, the surface with mingled fine
and coarse punctuation and finely pilose. The legs proportionally much
shorter than in modern Leptacini, but otherwise similarly constructed, and
the front tarsi dilated as much as in L. nigripennis LeC. Elytra a little
longer than the thorax, probably not much broader, squarely truncate at
apex, but with both outer angles well rounded, the whole punctate and
pilose like the thorax. The abdomen is seen laterally but appears to be
much slenderer than the elytra, with tolerably parallel sides, expanding
slightly to the fifth segment and then rapidly narrowing to a bluntly
rounded apex, the whole surface punctate and delicately pilose like the
other parts. The whole body and its appendages piceous throughout.

It is a much stouter form than L. maclurei, and its punctate body
separates it distinctly from that.

LEPTACINUS ? EXSUCIDUS sp. Nov.
Pl. VU, fig. 13.

The species here considered can hardly be congenerie with the modern
forms of this genus, nor with the other species from Florissant which are
here described as Leptacini. There appears to be absolutely no neck, and
the thorax is crowded closely both upon the head at one end and the elytra
at the other—and the straight equal and parallel sides of the body appear to
show that this is not a mere accident of preservation—so as to make it very
slightly resemble one of the tribe of Xantholini, to which otherwise it would

appear to belong. J have therefore placed it in the genus to which most of
the Florissant Xantholini are referred, until more material may give us better
means for judgment. It should possibly be placed in Othius.

The head is quadrate, of about equal length and breadth, with
scarcely rounded posterior angles, the surface feebly and shallowly
punctate, with scattered short hairs. Antenne poorly preserved but
evidently geniculate, reaching back nearly to the middle of the thorax
(which is not far, both head and thorax being so short), enlarging a little
apically, the terminal joints scarcely broader than long and the last
one subglobose. Thorax quadrate, scarcely so long as broad, with
straight and almost parallel sides, scarcely narrowing from base to apex,
where it is scarcely broader than the head, shallowly punctate and with
short scattered hairs. Legs rather short, the tibiz very slender. Elytra
apparently somewhat longer but scarcely broader than the thorax and
apparently with the same structure. Abdomen scarcely narrower than the
elytra, with straight and parallel sides, the apex bluntly rounded, the surface
faintly and minutely punctate.

LITHOCHARIS SCOTTII Sp. nov.
Pl. VII, fig. 16.

Head of about equal length and breadth, largest just behind the middle,
scarcely narrowing behind, with slightly rounded posterior angles, the base
truncate, the surface with scarcely perceptible delicate transverse rugze.
Slight traces of the palpi show nothing different from Lithocharis. Antenne
reaching to the end of the tegmina, rather slender, scarcely enlarging
apically, the joints long, ovate, but none of them greatly larger apically
than basally, the second and third joints not stouter than the others (in
which the species differs from L. corticina Gray., with which it otherwise
best agrees), the fourth to the sixth longest and about two and a half times
longer than broad, most of the others about twice as long as broad, the
apical joint globose and not enlarged. Thorax slightly broader than the
head, subquadrate, the sides slightly convex, all the angles equal and
searcely rounded, the surface apparently smooth, with a few very short,
delicate hairs and a faint median carina. Legs closely resembling those of
L. corticina, but shorter, and the tibiz: slenderer and scarcely enlarged
apically. Elytra considerably broader than the prothorax, longer than the
head and thorax together, with well-rounded humeral angles, similarly
rounded outer apical angles, squarely truncate apex, a slight sutural stria,
and a smooth surface with a slight covering of fine hairs. Abdomen beyond
the elytra about as long as the thorax and elytra together, broader than the
thorax, but narrower than the elytra, scarcely tapering apically to a roundly
pointed apex, the sides margined, and the surface apparently smooth and
slightly villous.

‘TACHINUS SOMMATUS Sp. NOV.
Pl. VIL, figs. 8-10.

Head small, triangular, broader than long, narrowing behind the eyes,
smooth, with excessively delicate transverse rugee. The slight remains of
the maxillary palpi show that they are not subulate. Antennz reaching
almost but not quite to the hind border of the thorax, only slightly enlarg-
ing apically, the first four smooth and naked joints differing from those of
T. fimbriatus Gray., with which this species agrees well in general appear-
ance and size, in that they are not so dilated apically and the fourth joint
is scarcely shorter than the third; neither are the fifth to the tenth joints
darker colored. and pilose as in the modern species, but they are not so
uniform, the fifth and sixth, and especially the fifth, being considerably
longer than broad, the seventh and eighth equally long and broad as in T.
fimbriatus, and the ninth and tenth broader than long; the last joint is pyri-
form but no larger than the tenth. Thorax shaped as in 7. fimbriatus, smooth,
or with faint signs of excessively delicate transverse ruge. Legs, excepting
the bases of the femora, not preserved in any of the specimens. Scutellum
considerably larger than in 7. fimbriatus. Elytra perhaps slightly broader
than the thorax, as long as the head and thorax together, the humeral and
outer apical angles more rounded than in the modern species mentioned,
apically truncate, the surface with the same transverse microscopic rugze
which characterize the head and thorax, and without any punctuation such
as is found in all the eight or ten modern species of Tachinus I have seen.
Apparently, too, the elytra are of the same light (reddish?) color as the
head and thorax, in contrast to the black abdomen, which tapers uniformly
to a dull point, the whole body being fusiform, but more pointed behind
than in front; the abdominal joints are margined and the surface indistinctly
punctate, clothed sparsely with short hairs and with four rows of long
spinous hairs attached to the hinder margins, one to a segment in each row,

one row at the sides, and one row laterodorsal. The fifth segment is only
about half as long again as the preceding, differmg markedly in this respect
from the modern species; the last dorsal segment is quadridentate (in the
female), resembling most in this respect the much smaller American species
T. tachyporoides and T. repandus Horn, but the lateral teeth are broader and
more conical than in either of these, a feature which is not found in any of
the species figured by Horn. They are slightly distorted in the specimen,

Head rounded, short, triangular, smooth, and piceous. Antenne
reaching to the end of the thorax, enlarging gradually and slightly, testa-

scarcely narrower than the elytra, the sides narrowing strongly toward the
apex, rounded, especially at the angles, squarely truncate at base. Elytra
together nearly half as wide again as long, longer than the head and thorax
together, squarely truncate at apex, the humeral angles well rounded, the
surface smooth, with occasional short bristles, and testaceous, deepening to
piceous on the basal two-thirds and sometimes including the whole of the
elytra. Abdomen narrower at base than the tip of the elytra, tapering
regularly to a rounded point, piceous on apical, dark testaceous on basal
half, the tips of the segments and to some extent the other parts at the
sides furnished with black bristles, the edge of the basal segment with four
rather large equidistant bristles just at the tip of the elytra, not preserved

The species placed here differ from the modern species of the genus I
have seen in one common character, the proportional shortness of the
thorax, more marked in some than in others, but in all but one (B. funditus)
strikingly apparent. As, however, this is in accordance with other differ-
ences of a similar nature apparently affecting all the Florissant Staphylinidee,
there seems to be no ground for hesitation in placing them here.

ing a little from base to apex, no longer than the head, smooth, luteo-testa-
ceous, shining. Legs short and slender. Elytra considerably broader than
the thorax and as long as or a little longer than the head and thorax com-
bined, a little wider than long, smooth and shining, fusco-testaceous and
apparently with a sutural, a marginal, and a pair of discal sharp striz,
scarcely punctured. Abdomen as broad at base as the elytra, beyond
regularly and gently tapering to a blunt point, the abdomen beyond the
tips of the elytra being half as long again as the rest of the body; the surtace
smooth, of variable color, the hinder edges of the segments, especially the
hinder ones, armed with numerous bristly hairs. The species is a large one,
and belongs apparently in the vicinity of those for which the generic name
Megacronus was proposed by Stephens.

BoLevTosius FUNDITUS sp. Nov.
Pl. VII, fig. 3.

Head long oval, tapering, apparently smooth, piceous. Antennz not
preserved. Thorax fully as long as the head, tapering strongly from base
to apex, smooth, piceous. Elytra broadening posteriorly, only a little longer
than the thorax, and much wider than long, smooth, piceous. Abdomen
longer than the rest of the body, a little narrower at base than the elytra,
beyond tapering very gently, the tip rounded; the surface is smooth, piceous,
almost entirely free from hairs, excepting a short and inconspicuous fringe
along the posterior margins.

This is an ordinary sized species, and appears to be of a uniformly
black color and unusually smooth; it is of about the size and form of our
B. cinctus Grav.

BoLETOBIUS DURABILIS sp. DOV.
Pl. VIL, figs. 4, 5.

Head small, elongate, half as long again as broad, with nearly parallel
sides, smooth, shining, fusco-testaceous. Antenne not long enough to reach
the hinder edge of the thorax, the first three joints long, very slender, smooth
and luteous, the first as long as the second and third, which are equal; the
remainder dark testaceous, bristly, growing constantly wider, the fourth as
long and nearly as slender as the third, and lighter in color than the others,
the fifth, sixth, and seventh nearly quadrate, the remainder broader than
long, the apical subglobose. Thorax much broader than the head even at
tip, tapering but little, with rounded sides, scarcely so long as the head but
nearly twice as broad as long, smooth and luteous. Legs too poorly pre-
served to admit of statement. Elytra as broad at base as the thorax,
broadening considerably on the basal half, slightly longer than the head
and thorax together and longer than broad, smooth, luteo-testaceous. Abdo-
men almost as long as the rest of the body, as broad at base as the elytra,
with parallel sides on the basal half, narrowing beyond to a rounded tip,
sparsely covered with bristly hairs, almost as frequent over the whole sur-
face as on the apical edges of the segments.

This species, on account of the excessive brevity of the thorax as well
as of the antennze (which, notwithstanding the shortness of the thorax, do not
reach its hinder edge) can hardly be compared with any of our modern forms.

BoLETOBIUS STYGIS sp. nov.
Pl. VII, fig. 7.

Head less than half as long again as broad, with nearly straight and
converging sides, smooth, piceous. Antenne reaching back almost to the
base of the thorax, very gradually enlarging from the fifth joint apically,
these joints stout, subquadrate, dark luteous, hairy, the fifth and sixth joints
slightly longer than broad, the seventh to tenth of nearly equal length and
breadth, scarcely cuneiform, the last largest and ovate, one-third as long again
as broad (the basal joints not preserved). ‘Thorax longer than the head,
but apparently broader at base than long, tapering regularly from base to
tip, the latter being as broad as the head, the disk smooth, shining, luteous.
Elytra apparently of same width as the base of the thorax, longer than
head and thorax, piceous. Abdomen not so long as the rest of the body,
as broad at base as the elytra, narrowing at first slightly, on the apical half
more rapidly, to a somewhat pointed apex. the surface blackish testaceous,
with some bristly hairs.

This is the smallest of the Florissant species and about as small as any
of our living American species; it differs from all I have seen in the char-
acter of the antenne, and like B. durabilis, to which of the Florissant species
it is most nearly allied, has a very short thorax, though not of such excessive
proportions as there.

Mycrroporus DEMERSUS sp. nov.
Pl. VIM, fig. 6.

Of the form and size of B. americanus Er., which it closely resembles.
Head rounded triangular, of equal length and breadth, fusco-testaceous,
smooth and shining. Antenne reaching a little farther back than the hinder
edge of the thorax, and therefore considerably shorter than in B. americanus,
imperfectly preserved, but so far as can be seen of precisely the same gen-
eral form as there, except in being somewhat slenderer, and with the same
form of such individual joints as can be made out (notably the fifth or
sixth and the last), except in their greater brevity, apparently uniformly
luteous. Legs rather short. Thorax slightly longer than the head, about
half as wide again as long, tapering, in front of the same width as the head,
scarcely broader behind than the base of the elytra, smooth, shining, and
luteous. Elytra slightly shorter than the head and thorax together, slightly
broader than long, smooth, shining, fusco-testaceous, with sutural, lateral,
and discal strize, having faint signs here and there of delicate sete in them.
Abdomen as broad at base as the elytra, about as long as the rest of the
body, tapering pretty uniformly to a dull point, luteous or luteo-testaceous,
the surface smooth and shining, apparently with no pubescence, but the
apices of the joints with a few fine setae which become coarse and longer
on the terminal joints, especially at the sides.

70 TERTIARY COLEOPTERA OF NORTH AMERICA.

BLEDIUS Leach.

A cosmopolitan, but prevailingly north temperate genus with numerous
species, of which more than forty are North American. In the earlier Ter-
tiaries of Europe a species has been described from Oeningen, another (as
a Stenus) from Aix, and the genus has been recognized in amber. In North
America half a dozen species are described from Colorado and Wyoming,
and besides these, one from the Pleistocene of Canada.

Two of the species from Florissant placed in this genus are remarkable
for the uniform, close, and coarse granulation covering alike head, thorax,
elytra, and abdomen, a peculiarity which seems to bring them nearest the
armatus group of our living American forms, though in none of these, so
far as I have seen them, is the abdomen closely granulate. With them
agrees very well the Stenus prodromus Heer from Aix, which I am strongly
inclined to think should be regarded as a Bledius. <A third Florissant speci-
men agrees still better with the same armatus group, the granulations of the
abdomen being comparatively infrequent, but in the coarse and heavy
antennee, with no slender joints near the base, it departs altogether from any
Bledius I have seen. In the fourth Florissant species and the two from
Green River the granulation is feeble and sparse everywhere or wanting,
and seems in all to be almost altogether or wholly wanting on the abdomen,
though one of the Green River specimens still seems to belong to the armatus
group, while closely resembling the fourth Florissant species in the form
of the prothorax. In all, so far as can be seen, the antennz are unusually
short.

ings. The antennz reach back to the middle of the thorax and are of the
same general structure as those of B. armatus Er. (except for the slighter
enlargement of the basal joint apically), with which this species agrees well
both im size and general appearance. The thorax is shorter than the head,
uniformly, heavily, and coarsely granulate, much more heavily than the
head, the granulations being rather ovate than round. The legs are of
much the same structure as in B. armatus, excepting that the hind tibize are
not quite so enlarged apically, but the legs are slightly shorter. The elytra
are granulate like the thorax and much longer than it. The thoracie sterna
are almost equally granulate, while the abdomen, which in the last two or
three joints tapers to a blunt point, is less heavily and less densely granu-
late, and here the granulations seem to be the bases of short delicate hairs.

It is possible that the specimen numbered 1.520 in the Princeton

it is generically the same.

BLEDIUS SOLI sp. nov.

Pl. VILL, figs. 10, 14.

The head is elongated rather than transverse; its surface, excepting on
the neck below, where it is marked exactly as in B. morsei, is granulate but
not prominently. The antennz reach to the middle of the thorax and
agree entirely in form and structure with those of B. morsei. Thorax shorter
than the head, nearly half as broad again as long, with gently convex sides,
the surface very coarsely granulate. Legs agreeing exactly with those of
B. morsei, but they are, if different, even shorter. Elytra as long as the
thorax and half the head, rather broader than long, at base only a little
broader than the thorax, coarsely granulate. Abdomen longer than the rest
of the body, narrower at base than the elytra, gradually tapering to a
bluntly rounded, narrow tip, coarsely granulate like thorax and elytra.
The whole body is piceous.

(Z TERTIARY COLEOPTERA OF NORTH AMERICA.

The species closely resembles the preceding in general appearance, but
is smaller and is at once distinguished by the equal density and coarseness
of the abdominal granulations as compared with those of the thorax and
elytra.

This species comes close to the fossil Stenus prodromus Heer from Aix,
which I should look upon as a Bledius.

BLEDIUS OSBORNI sp. nov.
Pl. VIU, figs. 11, 12.

This species, smaller than the last, but closely resembling it in general
appearance, differs from it and from 6. morsei in its more finely granulate
body and stouter legs, and from all other species described, living and fossil,
in the coarseness of the antennz. The body is piceous throughout. The
head is as broad as the thorax, subquadrate, of equal length and breadth,
the surface exceedingly finely granulate, or in places with irregular trans-
verse striation, which if broken by equally deep opposing striz would form
similar granulations. Antennze reaching to the posterior edge of the thorax,
stout, enlarging but slightly and with perfect uniformity from the second
joint outward, the first jomt not very long and not greatly enlarged apically,
the second scarcely smaller at base than the apex of the first, and as large
as it at apex, being like the succeeding joints cuneiform with slightly convex
sides and rounded apical angles, the second to the fourth joints a little longer
than broad, the fifth to the eighth about equally long and broad, the ninth
and tenth a little broader than long and half as broad again as the second,
the apical joint subrotund, slightly longer than broad. Thorax of the leneth
of the head, equal, the surface very finely granulate, the granules so arranged
as to give somewhat the appearance of longitudinal beaded combings.
Legs short and rather stout, the tibize scarcely enlargmg apically. Elytra
a little longer than the thorax, broader than long, delicately and rather
feebly granulate. Abdomen half as long again as the rest of the body, as
broad at base as the thorax, with parallel sides, tapering only in the last
three segments, the tip bluntly pointed, the surface delicately and especially
above rather sparsely granulate, very finely and very sparsely pubescent
both above and below.

BLEDIUS PRIMITIARUM sp. Noy.
Pl. VIII, fig. 13.

Head ovate, considerably longer than broad, with gently rounded sides,
strongly rounded posterior margin, and globose, prominent eyes, situated
laterally rather far back; surface smooth and shining, with irregular, excess-
ively fine transverse combings. Antennz reaching nearly to the middle of
the thorax, rather stout, not increasing in size much beyond the middle, but
with the usual contrasted slendemess at the base, the joints of the apical
half” only a little broader than long, the apical jomts subrotund. Thorax
subquadrate, much shorter and scarcely broader than the head, with gently
rounded sides, the angles nearly rectangular, blunt; surface like that of the
head. Legs very short, the femora only moderately stout, the tibiae stout,
increasing considerably in size toward the apex, with a single, rather slender,
interior, apical spine as long as the apical width of the tibia. Elytra scarcely
longer than the head, somewhat broader than the thorax, of about equal
length and breadth, the surface sparsely and very faintly punctate and with
exceedingly brief and sparse pubescence. Abdomen very short, not so long
as the thorax and tegmina together, at base as broad as the tegmina, the
basal half equal, beyond tapering rapidly to a rather blunt point, the sur-
face sparsely pubescent, but otherwise smooth except for a feeble, sparse,
and coarse punctuation laterally. Whole body piceous.

This species appears to be most nearly related to the annularis group,
but is very different in several points from any of the species belonging to
it I have seen, and is larger than all and much larger than most of them.

BLEDIUS FACORUM sp. Nov.
Pl. VII, fig. 9.

Head subquadrate, slightly longer than broad, with very gently rounded
sides, slightly prominent eyes, and roundly truncate hind margin; surface
with a fine, scarcely perceptible granulation. Antennz fragmentary and
detached, but apparently not reaching the middle of the thorax; the most
that can be said is that the basal joints (beyond the first) are slender, that
beyond they increase slightly in size and are scarcely broader than long on
the apical joints, the last of about equal length and breadth and obpyri-
form. Thorax about one-fifth broader than the head, transverse, being
about half as broad again as long, with gently convex subangulate sides,
acute anterior and slightly obtuse posterior angles, the front margin very
gently concave and hind margin as gently convex, the surface sparsely and
somewhat obscurely punctate. Elytra nearly as long as the head and
thorax together and somewhat broader than the thorax, slightly broader
than long, with rounded humeral angles, the apical margin truncate with a
slight obliquity, the surface faintly and sparsely punctulate, with faint signs
of a sparse pubescence; that the lateral declivent portion of the elytra was
separated from the dorsal area by a sharp carina is evident from the sharp
line which separates the here jointly flattened fields in the specimen from
base to apex; nothing of this sort appears in the modern species of Bledius
I have seen excepting next the humeral angle; but a nearer approach to it
is found in the neighboring genus Oxytelus; since, however, there is no sign
whatever in the present species of the broad thoracic furrows peculiar to
Oxytelus, I have preferred to consider this as belonging to the present
genus. Abdomen considerably longer than the rest of the body, nearly
as broad at base as the elytra, equal for some distance, but in the three
apical segments rapidly and conically narrowing to a blunt point, the surface
scarcely granulate, with no evident signs of pubescence.

The species seems to belong to the armatus group and to be most
nearly though still rather distantly allied to B. flavipennis LeC.

This species, though poorly preserved, would appear to be allied to the
last two species, but has head, thorax, elytra, and abdomen of equal breadth;
the head appears to be faintly marked with a rather coarse transverse comb-
ing, while the thorax and elytra are indistinctly and minutely granulated,
which may possibly be traced on the abdomen. It is perhaps nearer the
semiferrugineus group than any other.

PLATYSTETHUS Mannerheim.

This genus has a moderate number of species, nearly all of which are
found in the north temperate regions of the Old World. North America
has but a single living species, but two occur in the Oligocene of Colorado.

The two species placed here are remarkable for their close resemblance
to our American species in the surface structure of the upper side of the
body, and they agree well also in the more important features. They both
differ, however, in their shorter antenne, and each has certain peculiar
features of its own; in general, however, their affinities with a living type
is more marked than in any other group of Staphylinide.

PLATYSTETHUS CARCAREUS Sp. Nov.
Pl. IX, fig. 1.

Body piceous throughout, excepting the prothorax, which is dark tes-
taceous. Head rounded, transverse, slightly broader than long, the surface
apparently with fine transverse ruge. Antennz shorter than in our com-
mon P. americanus Er. (which it closely resembles in size, form, and general
proportions, as well as in minor characters), scarcely reaching beyond the
middle of the prothorax, of exactly the same structure as in our species.
Thorax fully as long as the head and somewhat broader than it, transversely
quadrate; its exact form can not be determined, but it would appear to be
broader posteriorly than in our modern species; it has a distinet median
stria, deeper than in the living form, and, like it, is sparsely punctate, the
puncta giving rise to delicate hairs, which are only half as long as in P.

Abdomen narrower than the elytra, much longer than the rest of the body,
gradually tapering to a pointed tip, each joint fringed with long, distant
hairs and at outer margin with a very long fine seta, the surface besides
very sparsely pilose and apparently punctate like the thorax and elytra, in
which particulars it again agrees well with the American species.

PLATYSTETHUS ARCHETYPUS sp. nov.
Pl. IX, fig. 2.

This species, agreeing better in form and size with our living American
species than the preceding, does not so well resemble it in structure. The
whole body is black. The head is subtriangular, of about equal length and
breadth, with rather prominent large eyes, which give a somewhat angular
outline to the sides; the surface is very sparsely and rather obscurely pune-
tulate, each punctuation giving rise to a short hair. The antennz are so
imperfectly preserved that not much can be said of them, but they appar-
ently agree in every respect with the other fossil species; at least they are
longer than the head, have a slender basal and a not greatly enlarged apical
portion. Thorax rather longer and much broader than the head, much
broader than long, truncate at base and apex and with subangulate sides;
there is a fine median stria and a pair of distinct sinuate oblique carinze on
the disk, each running from one of the anterior angles to the middle of the
base, but fading at either extremity; the surface is otherwise precisely simi-
lar to that of the other fossil species. Elytra considerably broader than the
thorax, longer than the head and thorax together, scarcely longer than
broad, with the same surface structure as the thorax, but apparently with
longer hairs. Abdomen rather shorter than the rest of the body, a little
narrower than the elytra, scarcely broadening posteriorly for the first four
segments, behind that broadly rounded and scarcely produced, the surface
with scarcely perceptible, very sparse punctuation, but with hairs like those
of the thorax, and no perceptible fringe or lateral sete to the joints.

GEODROMICUS ABDITUS sp. nov.

Pl. IX, fig. 3.

Unfortunately the single specimen on which this species is founded
lacks the head, but as the form and surface structure of the other parts is
somewhat peculiar, it is with little doubt that we place it here. The thorax
is scarcely broader than long, the front and hind margin truncate, the sides
strongly convex and slightly angulate just in advance of the middle, the
hind margin therefore a little narrower than the front margin, the angles
scarcely rounded; there is a slight median impressed line, and the whole
surface is very delicately granulated, with scattered short delicate hairs.
The elytra are half as broad again as the thorax, but narrow toward the
base; they are nearly twice as long as the thorax, and they are together
angularly emarginate at apex, and delicately margined laterally; the surface
structure is the same as that of the thorax, only the granulations are a trifle _
coarser. The abdomen is scarcely so long as the thorax and elytra together,
long ovoid, narrower at base than the elytra, beyond equal to it in breadth,
roundly pointed at apex; the surface is vaguely granulated and very sparsely
and briefly pilose. The whole body is piceous.

ADALIA SUBVERSA sp. Novy.
Pl. IX, fig. 6.

A single specimen of a beetle is preserved, showing, indeed, very
few structural features, but in its form, size, and in its markings reminding
us of the common “lady-bird” which crawls up our window panes in the
spring. It is preserved on a. dorsal view and shows head, thorax, and
elytra in tolerably good preservation, together with one of the front tibiee.
The form and proportions of the prothorax and elytra are exactly as m
Adalia bipunctata (Linn.), but they are more coarsely punctate, though there
is the same distinction between the thorax and elytra in the shallowness of
the thoracic puncta. The insect appears to have been uniformly light
colored, with only two submarginal lateral dark spots on the prothorax (in
which it agrees better with Adalia frigida Schn. than with other species
of Adalia) and a rather large central spot on each elytron. In the generally
uniform light color of the thorax it differs from any of the living species in
the United States. It is also rather larger.

CHILOCORUS Leach.

A cosmopolitan genus with a considerable number of species, of which
a large part are tropical or subtropical, and only two occur in the United
States and two others in Europe. Yet three species have been found in
the early Tertiaries of these countries, two in Alsatia and one in Colorado.

COCCINELLIDA—EROTYLID 2. 81

CHILOCORUS ULKEI sp. noy.
Pe IEXS tos 8:

Two specimens are here referred to this genus, although, possibly by
the conditions of preservation, they differ from the members of this group
in one of its most distinguishing characteristics, the deep and sudden ante-
rior emargination of the prothorax. In the fossil it hardly appears to be
much more emarginate than in other neighboring Coccinellidee; but the
expanded genze of the head, the small size of the prothorax, the rotundity
and unusually dark evlor of the elytra, which are here piceous, and the
general form of the whole body make it tolerably certain that it belongs in
this group, and the absence of any visible sign of a labrum indicates that
it should be placed here rather than in Exochomus. It is of about the same
size as our native species, or a trifle smaller. The shape of the elytra is
the same, excepting that the humeral angle is scarcely so prominent; they
are, however, uniformly black, and more coarsely, heavily, and distantly
punctate than in C. bivulnerus Muls.; the shape of the prothorax is also the
same except for the lesser emargination, which scarcely appears in the
specimen selected for illustration and which is obscure at this point; the
prothorax is less deeply punctate than the elytra, but differs from our mod-
ern species in the same way as do the elytra; its disk is dark like the elytra,
and the head is imfuseated, but the sides of the prothorax are of a light
color and were probably red in life. One antenna is preserved on one
specimen, showing a considerably stouter club than in C. bivulnerus.

Length, 4.5 mm.; breadth of thorax, 2 mm.; of elytra, 3.5 mm.

CUCUJID 4.

A half dozen species of this family have been found in the older Terti-
aries of Europe and North America, equally divided between the two both
as to species and genera, one genus of the five recognized having been
found in both countries. One of the American genera is regarded as
extinct.

PEDIACUS Shuckard.

A north temperate genus, with a limited number of specific forms, of
which three occur in North America. One fossil is known, coming from
Colorado.

The single species found fossil in Americais peculiar for the brevity of
the antenne, the similarity in size of the first joint to the succeeding, the
lack of a distinct collar of equal width at the back of the head (notwithstand-
ing the presence of the transverse ridge behind the eyes) and the absence of
any sinuation or denticulations on the side of the prothorax.

PEDIACUS PERICLITANS sp. Nov.
Pl. IX, fig. 7.

The single specimen referred here agrees very closely with our native
species of Pediacus, and especially with P. depressus Herbst, excepting in
the absence of a collar-like neck to the posterior part of the head and in
having shorter antennz. The shape of the head is the same, with promi-
nent, coarsely faceted eyes, a flattened quadrate snout, nearly as long as
the head in front of the transverse ridge; behind the ridge the head con-
tinues to narrow. The first joint of the antennze is scarcely larger than the
second, and the second to the seventh are equal in size, and appear to have
a median ridge or furrow above; the entire length of the antennz is shghtly
less than the width of the prothorax. Prothorax subquadrate, broader than

margin scarcely convex, the sides well rounded and entire, with no aneula-

not much longer than the elytra, the front margin straight, the hind

tions, the front and hind angles nearly equally rounded. Elytra entirely

there slightly more distinctly punctate. Scutellum transverse, small.

Florissant, Colorado; one specimen, No. 112.

LITHOCORYNE (A/60s, xopvvn) gen. nov.

Closely allied to Lathropus Erichson, from which it differs principally
in the narrower head and the structure of the antennze; of the last, which
are as long as the head and half the thorax, the first joint is large and stout,
but longer than broad and only half as broad again as the joints beyond; the
second of entirely similar size to the following, or a very little shorter, and,
with the third to the eighth, obconic, truncate, longer than broad; the ninth
to eleventh enlarged into a distinct club; the ninth and tenth hemispherical,
truncate at tip, nearly twice as broad as long; the terminal segment broad
ovate, longer than broad, but scarcely narrower than the preceding. Pro-
thorax narrowed posteriorly, without lateral denticulations, the hind angles
rounded, the surface depressed, as in Cucujus.

The single species known is of about the size of the living species of
Nausibius or of Pediacus, and much larger than those of the more nearly
related Lathropus. _

LirHocoRyNE GRAVIS sp. nov.
Pl. IX, fig. 4.

Head, including the mouth parts, shorter than broad, the rather large
eyes scarcely disturbing the full contour of the sides, distant from the pro-
thorax, but little narrower behind and about three-fourths the width of the
thorax; sculpture of the surface similar to but more subdued than that of
the prothorax; antennal stalk moderately slender, the whole reaching to the
middle of the prothorax. Prothorax nearly twice as broad as long, broadest
anteriorly, very gradually and regularly tapering to the base, which is
about a seventh narrower than the front; in front the sides are suddenly
turned inward, and the lateral angles, which are sharp, are produced forward,

but otherwise the front is truncate; base very gently convex, the outer
angles gently rounded; the sides are narrowly margined or the margins
thickened as in allied genera, but they are entire and nowhere denticulate;
surface covered with minute not crowded nor prominent granulations.
Elytra near base a third as wide again as the base of the thorax, the sides
parallel, the shoulders abruptly rounded, with sculpturing similar to that of
the thorax but less pronounced; their tips are broken in the only specimen
known, but they are evidently at least half as long again as the head and
thorax together and not much more than that.

PARANDRITA LeConte.

A monotypie genus, occurring in Arizona and California. The only

The prothorax, from which the head can not be separated, is triangular with
rounded angles, the middle of the hind margin produced but rounded
apically, the whole surface feebly punctate, but with larger puncta than in

CARPOPHILUS Stephens.

A cosmopolitan genus with numerous species, many of which occur in
North America. The only known fossil species is the one here described
from Colorado.

CARPOPHILUS RESTRUCTUS sp. Nov.

Pl. LX, fig. 9.

Form pretty regularly ovate. Head large, about half as large as the
prothorax, full and rounded, subsemicircular, glabrous, the mandibles of the
normal form. Thorax at base of the size of the there narrowed elytra,
narrowing considerably, with rounded sides on the anterior half, the front
margin being straight and scarcely broader than the base of the head;
posterior margin straight, the outer angles scarcely rounded, the base
scarcely narrowed, the surface glabrous. Scutellum very large, glabrous.
Elytra almost as long as the head and thorax together, the sides nearly
parallel but well rounded, and to that extent narrowed at base and apex,
‘truncate, the apical margin faintly convex, the whole surface glabrous.
Abdomen having the second and third segments together shorter than the
fourth (showing that it falls in the subgenus Carpophilus, as characterized
by Andrew Murray), the fourth and fifth equal and together nearly as long
as the elytra, fully exposed and sparsely clothed with moderately long
villous hairs.

Length, 3.2 mm.; breadth, 1.5 mm.

This species seems to belong in the subgenus Carpophilus, in the near
neighborhood of the widely distributed species C. hemipterus (Linn.), but
differs remarkably from it in the great size and fullness of the head and the
glabrous surface of most of the body.

Florissant, Colorado; one specimen, No. 1400.

EPANURAA (éza@v@, ovpa@) gen. nov.

Allied to Epurzea, with the same general form, but with a relatively
larger head and peculiar antenne. These are shorter than the width of the
body and beyond the large basal joint consist of ten joints, of which five
go to form the remarkably short, slender stem, in which the joirits are hardly
longer than broad, and together are shorter than the apical five which form
the abrupt club; this is a little more than twice as broad as the stem, and

consists of two portions; the first of a single (the seventh) joint which is
subcireular and sharply separated from the remainder (though not appear-
ing so in the published figure), which are closely united and equal, excepting
that the last is minute.

A single species is known, and comes from Florissant.

EPANURHA INGENITA.
Epanurea ingenita Scudd., Tert. rhynch. Col. U. 8., pl. 1, fig. 2 (1892).

Head large, fully two-thirds as wide as the prothorax, and two-thirds as
long as broad, the front well rounded, the surface feebly punctate; eyes
large, lateral. Prothorax more than half as broad again as long, tapering
slightly, with rounded sides, the front feebly and broadly emarginate, the
surface more distinctly punctate than the head. Elytra a little broader at
base than the thorax, with strongly pronounced impunctured striz. Legs
moderately short and not very slender, the tibise with long and delicate
spurs.

Length, 4.6 mm.; breadth, 1.9 mm.

NITIDULA Fabricius.

A cosmopolitan genus with not a great many species, three only of
which occur in the United States. Eight species of the genus have been
found in the early Tertiaries of Oeningen and Radoboj; it has also been
recognized in amber, and one species occurs in Colorado.

NITIDULA PRIOR sp. nov.
Pl. IX, fig. 11.

Body oblong ovate, broadest at the elytra. Head large, transverse,
well rounded, broadest posteriorly, half as broad again as long, with no
sign of emargination in front of the eyes, which do not disturb the even
contour of the sides. Prothorax rather short, at its broadest twice as broad
as long, broadest at base, with pretty regularly rounded sides, but tapering,
especially in front, where it is only a little wider than the head, the sides
scarcely if at all marginate; base apparently regularly truncate, the front
rather deeply emarginate; surface both of head and thorax uncertain, but
showing in certain places as delicately rugulose in a transverse sense.

88 TERTIARY COLEOPTERA OF NORTH AMERICA.

Scutellum rather large, triangular, equiangular, the posterior angle well
rounded. Elytra at base of the extreme width of the thorax and subpar-
allel, together a third longer than broad, and half as long again as head
and thorax together, truncate, with rounded apex, exposing two abdominal
segments, with faint and rather numerous striz, the interspaces exceed-
ingly finely and delicately punctulate. Abdomen faintly punctate. No
signs of any villosity in any part of the body, but this may be accidental,
as the tibize appear to be as villous as in the modern species of Nitidula.

The species does not appear to be at all nearly related to any of our
living native species, and the form of the head, the absence of any inde-
pendent prominence of the clypeus, with the rapidly narrowing thorax and
striate elytra, lead one to suspect that it will be found impossible to retain
it in this genus. The general aspect is that of Nitidula rather than of any
other genus of the family, and the legs have a similar structure. Unfortu-
nately the antennze are not preserved. It is nearest N. rufipes Linn.

NOosoTETOCUS DEBILIS Sp. nov.
Pl. X, figs. 1, 2.

Form very broadly oval, the length being about a third greater than
the width, the head not disturbing the regularity of the contour. The head
is rather small and transverse, with rather broadly rounded front; in one
specimen it is unnaturally raised so that the actual form can easily be seen.
The antennze are somewhat more than half as long as the breadth of the
broad body, and the apical joint, considerably larger than any of the others,
is twice as broad as the slenderer joints of the stem. The elytra show very
feeble indications of punctures longitudinally disposed, but not shown in
the plate. The under surface of the body appears to be smooth, excepting
the episterna, which are coarsely granulose.

Florissant, Colorado; two specimens, Nos. 9231, 11303.

NOosOTETOCUS VESPERTINUS sp. Nov.
Pl. X, fig. 3.

Form regularly obovate, about half as long again as broad. The head
is comparatively small, transverse, the antennz about half as long as the
greatest width of the body, the third and fourth joints narrowest and about
two-thirds the width of the apical joint, which is largest and well rounded
apically. The under surface of the body is exposed in the only specimen
discovered and is apparently smooth throughout, but where the tips of the
parted elytra show through the body they appear faintly and somewhat
uncertainly as if feebly punctured in rows. The hind femora are consider-
ably expanded, largest in the middle and about twice as broad as the
straight and equal tibize.

AMPHICYRTA INHHSA sp. NOV.
Pl. X, fig. 10.

A single fairly well preserved specimen of a byrrhid from Florissant
seems referable to Amphicyrta. The form of the body is oval, broadest
posteriorly, and the size and general appearance not unlike 4. dentipes Er.
of the Pacific coast. The head is rather narrow, and the labrum remark-
ably narrow for its length, being scarcely transverse, with strongly rounded
front margin. A few joints of one of the antennze are seen crossing the
thorax, but present nothing peculiar. The elytra are sparsely and shallowly
punctate with circular puncta, removed from one another by at least double
their own diameters, and thus very closely resembling the sculpturing of
the elytra of A. dentipes if the puncta of the latter were slightly smaller
and more shallow.

Length, 6.25 mm.; breadth, 5 mm., as preserved with partially expanded
elytra, but the probable actual breadth is 4.25 mm.

the American species, and is double their size. The general form is uni-
formly oval excepting for the slight prominence of the head, which may be
entirely due to the state of preservation; the head is about half the width
of the body. The elytra are furnished with rather deep and sharp striz, as
in existing species of Cytilus, but are distinctly though finely punctate, and
the legs appear to be very different from Cytilus. The tibize have their
opposite sides similarly and very slightly arcuate, and in the middle legs
are as broad as the femora, though not more than two-thirds their width in
the hind legs. The hind tarsi are as long as the hind tibiz, the last joint
and claws quite as in the living Cytili. The specimen shows no antennze
and is somewhat mutilated behind.

Florissant, Colorado; one specimen, No. 7740.

CYTILUS DORMISCENS.

Cytilus dormiscens Seudd., Tert. rhynch. Col. U. 8., pl. 1, fig. 1 (1892).

Head very finely and profusely punctate, with some fine wrinkles above
the rather large eye; antennee hardly longer than the head, the terminal
joints a third broader than the basal, of about equal length and breadth.
Thorax apparently tapering but little, and so having an appearance very
unlike a byrrhid, but this is apparently due to distortion in preservation; it
is much broader than long, truncate at both extremities, finely, profusely,
and uniformly punctate. LElytra similarly but not so heavily punctate,
with faint signs of delicately impressed striz. Femora rather stout, tibiee
moderately so, tapering at either end, with a few delicate spines. Under
surface of thorax punctured like the elytra, of abdomen nearly or quite
smooth.

Length, 5.5 mm.; breadth, 3 mm.

The short antennze hardly agree with Cytilus.

is recognized in the English Pleistocene, and three species have been found

BYRRHIDZ. 93

m the older Tertiaries of Oeningen and the Rhine, and another in amber.
In America two fossil species are known, one from the Canadian Pleistocene,
the other from the Oligocene of Colorado.

The Florissant species here described agrees tolerably well in structure,
as far as can be seen, with modern types, but has certainly a much more
regularly oval contour to the body. The head is retractile; while in the
species described from the European Tertiaries, or those best figured, it
does not appear to be so, so that they are probably wrongly placed here,
belonging rather to the Nosodendrine.

ByRRHUS ROMINGERI Sp. Nov.
Pl. X, fig. 9.

A species of about the size of B. geminatus LeC. and agreeing fairly well
with it in the sculpturing of the elytra and the granulation of the under sur-
face of the abdomen, but differing from the Byrrhi in the more regular
contour of the oval body, the lack of a humeral thrust at the base of the
elytra, and the want of any prominence to the head. The antenne are as
long as half the width of the body, the joints increase more gradually in
size than in B. geminatus, and the last joint has a greater proportionate
size. The hind tibize are slender, but little expanded, and scarcely half as
wide as the femora; the hind tarsi are apparently quite as in the modern
species. The elytral striation is indistinct and apparently of much the
same character as in B. geminatus.

PSEPHENUS Haldeman.

This is a North American genus with only two species. A single fossil
species occurs in Colorado.

PSEPHENUS LUTULENTUS sp. nov.
Bl Mesfio Sian

Ovate. Head with perfectly regular semicircular front with a curve
that, apart from the eyes, would make the head longer than broad. Eyes
protuberant, globular, much more than half as long as the head. Antenne
reaching fully to the base of the elytra, moderately slender, the somewhat
moniliform joints increasing slightly in size to the tip, the apical jomt sub-
globular, slightly elongate. The pronotum broadens far less rapidly than
in the existing P. lecontei LeC., and is much shorter than there, being at the
greatest not much longer than the anterior breadth, but has the same
sinuate hind margin as in the modern species; the anterior lateral angles
are joined by a semicircular impression, and behind it, parallel to and so
concentric with it and lying midway between it and the hind margin, is a
second similar line. The surface both of head and thorax appears to have
had a similar seulpturing, which looks as if consisting of crowded shallow
depressions about as large as the facets of the eye. Scutellum slender,
moderate. Elytra with the same sculpturing as the head and thorax, more
than twice as long as they, broadest at end of basal third.

HLATEHRID 4.

In this family, beginning the Serricornia, and in the succeeding families,
but very few of the American fossil species known to me are described or
considered. It may nevertheless be well to continue in each case the brief

summary of our present «<nowledge of the fossil forms, although most of
the material must be taken from foreign sources. The American contingent,
however, being so small, will not be contrasted with the European as here-
tofore, except so far as it may appear desirable.

About fifty-eight fossil species of this family have been described or
indicated—in a less degree than usual described or figured. They repre-
sent twenty-one genera, of which only one, an American, is regarded as
extinct. Fourteen of these species, of five genera, come from the Pleisto.
cene, the remainder, but including three of the Pleistocene genera, from the
earlier Tertiaries. Two of the Pleistocene forms, one on each continent,
are regarded as existing species.

ADOCETUS (a@doxnzos) gen. nov.

Head very large indeed, together with the large eyes fully as broad as
the front of the pronotum, the front broad, truncate or feebly rounded;
antenne obscurely preserved, but apparently much as in Scaptolenus, but
with much less apical enlargement of the joints. Prothorax strongly trans-
verse, nearly twice as broad as long, considerably and rapidly tapering, the
front margin about three-fourths the length of the hind margin, gently and
uniformly emarginate; hind margin scarcely angulate, sides scarcely arcuate,
the outer anterior angles rectangular; both lateral and front borders equally,
broadly, and regularly margined, the outer posterior angles rounded and in
no way produced. Elytra at base of the breadth of the thorax, regularly
tapering by the arcuation of the outer margin, the apex perhaps pointed.
Hind coxe very large, somewhat produced posteriorly next their inner side,
the legs large and stout and apparently flattened. Abdomen with six seg-
ments, the first five of equal length and truncate, the sixth longer and conical.

The single species referred here has a close resemblance in general
outline to a buprestid like Psiloptera, but the separation of the first and
second ventral segments shows it to be an elaterid, the transverse labrum
and the number of ventral segments a cebrionine.

ADOCETUS BUPRESTOIDES Sp. nov.

Surface of head more or less bluntly and rather finely rugulose.
Thorax more heavily and more distinctly rugulose, and at the same time
sparsely punctate, the puncta more distinct, because not confused by
rugee, on the front margined area; apparently also clothed with very

sparse, very short and fine hairs. Elytra each three and a half times
longer than broad, with ten faintly punctate striz, of which the sixth and
seventh (or seventh and eighth) from the suture terminate before the
others, at about the base of the apical fifth of the elytra, the others close to
or at the tip; the interspaces are sparsely and irregularly punctate, the
equivalent of not more than two series of puncta in each interspace, each of
the puncta giving rise to a very short fine hair. Abdomen feebly punctate,
the last segment with fine, short, transverse, arcuate incisions.

Length, 22 mm.; breadth, 8 mm.

them regarded as extinct. With a single exception, none of these species
come from the Pleistocene. Besides these, however, a considerable number
of species have been referred to the family without even generic reference,
from India, New South Wales, and various localities in England, including
one in the Pleistocene.

CHRYSOBOTHRIS HAYDENI.
Pl. XI, fig. 1.

Chrysobothris haydent Scudd., Bull. U. S. Geol. Geogr. Surv. Terr., II, 80 (1876).

A single specimen, rather poorly preserved and obliquely crushed, was
obtained by Dr. F. V. Hayden at what was then known as Castello’s ranch.
While it is unquestionably a buprestid, I place this species in Chrysobothris
with some hesitancy. The shortness of the broad-tipped elytra, the rotund-
ity of the eyes, and the comparatively slender fore femora separate it from
the species of that genus which I have examined. The head is large, full,
well rounded; the eyes moderately large, nearly circular. The prothorax
is rather short, arched a little, minutely and shallowly punctulate. The
elytra reach to the base of the penultimate abdominal segment, and, as
exhibited on the stone, are as broad at tip as at base; the apex in any case
is broad, broadly rounded, or almost truncate; there is no appearance of
punctures, although there seem to be three or four faint equidistant longi-
tudinal ridges. A fragment of one of the wings is seen extending at right
angles to the elytra. The legs are slender and the fore femora resemble
the others.

Length of insect, 15.75 mm.; of prothorax, 3.75 mm.; of elytra, 10
mm.; width of elytra at tip, 2.6 mm.; length of fore femora, 3.25 mm.;
of hind femora, 3.25 mm.; breadth of fore femora, 0.56 mm.; of hind
femora, 0.46 mm.

CHAULIOGNATHUS Hentz.

An American genus, with a moderate number of species. One species
has been found fossil in Colorado.

CHAULIOGNATHUS PRISTINUS.
Pl. XI, fig. 3.

Chauliognathus pristinus Seudd., Bull. U. S. Geol. Geogr. Surv. Terr., II, 81 (1876);
in Zittel, Handb. Paleont. (I), Il, 769, fig. 1032 (1885).

A single specimen, with its reverse, was obtained by Mr. T. L. Mead at
what was then known as Castello’s ranch. It is very fairly preserved and
presents a dorsal view of the insect, with the left elytron and wing par-
tially expanded. The antennz are about as long as the elytra, and appar-
ently consist of twelve joints, most or all of which are similar to one another,
cylindrical, about three times as long as broad, and scarcely smaller at the
proximal than at the distal extremity. The prothorax is small, scarcely
larger than the head, the anterior border rounded. The elytra are slender,
square at the shoulder, each independently rounded and slightly tapering
at the apex, not reaching the tip of the abdomen. The abdomen, which
tapers posteriorly, appears, however, to be unnaturally produced; more
than four segments can be counted upon the unexpanded elytron. The
wings are only as long as the elytra. The legs are slender, but the tarsi are
indistinguishable.

But for the brevity of the elytra there would be little doubt that this
insect should be referred to Chauliognathus. It has the general appear-
ance, also, of a Malthinus or a Malthodes, but the wings are not exposed
when the elytra are closed, and the insect is much larger than the living
species of this genera. Heer has described, from Oeningen and Radoboj,
several species of this family, but none so large as this, unless it be his
Telephorus germari. Our species has much the general appearance of his

gated. The head is less than half as long as the prothorax, with less
prominent and more nearly approximate antennal tubercles, as compared
with Lamia. Antenne: moderately slender, half as long again as the
body, composed of eleven joints, each cylindrical, scarcely enlarged at the
distal extremity ; the basal jomt is short and stout, its length less than half
the width of the head, twice as long as broad, tapering apically almost as
much as at base; the second joint small, of equal diameter with the sue-
ceeding, and broader than long; the remaining joints almost imperceptibly
decreasing in length, each equal im width until close to its tip, when it
expands very slightly, the terminal joint a little shorter than the penulti-
mate. Prothorax transverse, with a not very large spine on either side;
scutellum larger than in Lamia. Elytra not connate, together more than
half as broad again as the base of the pronotum, but with rounded humeral
angles, not in the least produced, and with no basal tubercles ; they are
nearly parallel in their basal half, but beyond taper regularly though but
slightly, the tip rounded, but not so declivent exteriorly as in Lamia. Last
segment of the abdomen transverse, but longer than in Lamia, broadly and
regularly rounded, with no excision of the apex.

This insect is interesting from its belonging to a group not now repre-
sented on this continent, the true Lamioides, which are found exclusively in
Europe and Africa and have their home in the Mediterranean region. Our
nearest living allies are the species of Monohammus. In its form and the
surface sculpture it most recalls the genus Lamia proper, but differs from it
as well as from the neighboring genera in important particulars, which will
perhaps be increased in number when other specimens are found which
will permit us to know the peculiarities of the structure of the legs and the
sternal surface.

PAROLAMIA RUDIS.

Parolamia rudis Seudd., Bull. U. S. Geol. Geogr. Surv. Terr., IV, 530 (1878).

The elytra are parted and thrust forward upon the prothorax, conceal-
ing the outer posterior portions of the latter, but this permits the abdomen
to be seen, and all other parts which could be seen on a dorsal view are
present excepting the legs. The head is nearly smooth, or appears to be

CERAMBYCID—CHRYSOMELIDZ. 107

slightly scabrous; the antennze are nearly smooth, the basal joint mesially
carinate above, the last joint bluntly pointed. Prothorax subquadrate, a
little transverse, the extent of the lateral spines concealed, the surface rather
coarsely and pretty uniformly scabrous. Elytra coarsely granulate at the
base, the granulations becoming gradually fainter until they disappear, the
apical quarter being free, although the surface is not uniform; outer and
inner edges minutely marginate. A fragment of one of the wings remains,
showing that the insect was not apterous.

ORYCTOSCIRTETES Scudder.
Oryctoscirtetes Scudd., Bull. U. S. Geol. Surv. Terr., II, 82, 83 (1876).

This genus belongs to the group of Chrysomelidee, of which Haltica
Illiger is the best known representative, the members of which are peculiar
for their swollen hind thighs, enabling them to spring to great distances.
It appears to belong to the group of C&dionychites, in which the last tarsal
joint has a more or less prominent bulbous expansion on the hind legs; but
it differs from any of the genera described by Chapuis in the nature of this
expansion, as well as in other tarsal peculiarities. The basal joint of these
hind tarsi is moderately long and cylindrical, scarcely larger at the distal
than at the proximal extremity; the second and third joints are subequal,
the latter slightly the larger, together as long as the basal joint, moderately
lobate, the lobes pointed; while the apical joint is nearly as long as all the
other joints combined, enlarges gradually from base to apex, so as to be
fully two or three times as large at the distal as at the proximal extremity,
and bears a pair of exceedingly long and slender, apparently simple, very
slightly curved claws, nearly half as long as the apical joint itself. In
other respects it closely resembles the genus Cidionychis Latr.

It is represented by a single species in the Oligocene of Colorado.

ORYCTOSCIRTETES PROTOGEUM.
Pex etiga lel
Oryctoscirtetes protogeum Seudd., Bull. U. S. Geol. Surv. Terr., II, 83 (1876).

A single specimen, pretty well preserved, and showing the dorsal sur-
face, was obtained by Dr. F. V. Hayden at what was formerly known as
Castello’s ranch. The head is pretty large, nearly as broad as the prothorax,
the eyes moderately large, apparently circular, with. large facets, their
average diameter being nearly 0.02 mm. The prothorax is broad, with

112 TERTIARY COLEOPTERA OF NORTH AMERICA.

well-rounded, somewhat convex sides and front lateral angles, the anterior
margin considerably concave; the posterior lateral angles are rectangular
and there is apparently a median furrow on the posterior half, although the
appearance may be due to crushing. The surface of the prothorax, and
also of the elytra, is very delicately granulate; the elytra are also furnished
very indistinctly with several (five or six?) longitudinal ridges, straight and
equidistant. The fore femora are swollen as well as the hind pair, but the
middle femora are concealed. Both middle and hind tarsi have the charac-
ters mentioned in the description of the genus and are fully four-fifths as
long as their tibie.

Length, 5 mm.; breadth, 2.25 mm.; breadth of head, 1.25 mm.; of
prothorax, 1.8 mm.; length of prothorax, 0.92 mm.; of elytra, 3 mm.; of
middle tibize, 1.34 mm.; of middle tarsi, 112 mm.; of middle claws, 0.18
mm.; of hind femora, 1.32 mm.; of hind tibiz, 1.4 mm.; width of hind
femora, 0.48 mm.; of hind tibize, 0.18 mm.; length of hind tarsi, 1.14 mm.;
of first joint, 0.32 mm.; of fourth joint (excluding claws), 0.48 mm.; of
claws, 0.22 mm.; breadth of fourth joint at tip, 0.1 mm.

g
Two specimens, reverses, but one showing more plainly the upper, the
other the under surface, were found by Mr. T. L. Mead. They are in an
unusually good state of preservation. But very little of the small head
can be seen, either upon the upper or the under surface; the portion exposed
is delicately punctured, the punctures being closely crowded, and rather
less than 0.01 mm. in diameter. The antennze show nine joints, which are
together longer than the breadth of the prothorax; the first and second
joints are ovate, the remainder more or less obconical; the first four are of
nearly equal length, and of about equal length and breadth; beyond, the
joints are subequal among themselves, but much longer than broad. The
prothorax is crushed and although not displaced, it is difficult to determine
its exact form, or whether or not it wholly concealed the head from above.
It is more coarsely punctate than the head, the punctures being 0.025 mm.
in diameter; the posterior border is broadly angulate, the angle rounded,
the outer margin more or less rounded, and the whole prothorax broadest
posteriorly. The elytra are very ample, equal, each independently very
broadly and regularly rounded at the apex, which does not reach the tip of
the abdomen; they are very distinctly but narrowly punctato-striate, in
nine straight, equidistant, complete rows, besides an auxiliary row next the
outer margin for a portion of the distance; near the tip of the elytron the
outer and inner rows curve toward the middle of the apex and all fade out
before reaching it; the entire border of the elytra is marginate. The
femora, especially the hind pair, are stout; the hind tibize are considerably
shorter than the femora and there are, apparently, on one side, faint indica-
tions of the two long tibial spurs, with which the apex of the hind tibiz is
armed in this genus. The abdomen is exceedingly short and broad, the
apical segment protruding a little beyond the others and well rounded.
Length of body, 5.25 mm.; breadth of prothorax, 2 mm.; of body at
middle of elytra, 3.25 mm.; length of antenna, 2.2 mm.; of elytra, 3.75
mm.; breadth of same, 1.35 mm.; length of middle femora, 1.05 mm.;

BRUCHUS Geoffroy.

A dominant cosmopolitan genus, with abundant representation in North
America. Seven fossil species have been recorded from the early Tertiaries
of amber, Rott, Oeningen, Alsatia, and Utah. One of the two species found
in the Oligocene of Alsatia is regarded by Forster as identical with a living
form.

TEN EHBRIONID 4.

Twenty species of this family have been found fossil, referred to eleven
genera, one of which is regarded as extinct. Only two of these species
occur in the Pleistocene, one in America, the other in Europe, belonging to
different genera; the European species is regarded as identical with a living
form. Besides these, undetermined genera have been found in various
localities.

TENEBRIO Linné.

A cosmopolitan genus with relatively few species, four of which occur

in the United States. Two fossil species are found in the brown coal of the

Rbine, one in the Tertiaries of British Columbia, and one in the Canadian
Pleistocene.

ing here.

EPHALUS? ADUMBRATUS.

Ephalus? adumbratus Scudd., Tert. rhynch. Col. U. S., pl. 1, fig. 3 (1892).

Head large, apparently almost as broad as the prothorax, but all the
specimens give a side view only, the surface uniformly granulose; eyes
moderately large, nearly circular, but a little transverse; antenne rather
coarse, especially the apical half, where the joints are nearly twice as long
as broad, the whole hardly reaching back to the elytra. Thorax granulose,
exactly like the head, both anterior and posterior margins straight and trun-
cate in most of their course, a distinct lateral plica or carina, the whole
much broader than long. Elytra with well-rounded humeral angle and
feebly punctured striz. Legs, especially tibize, slender, the spurs small,
the anterior pair broader, with prolonged outer angle.

Length, 4.6 mm.; breadth, 2 mm.

I have placed this species in Ephalus with some doubt, but it seems to
belong in the Opatrini, and I find nothing nearer in point of structure.

Florissant, Colorado; three specimens, Nos. 6506, 7646, 14247.

HELOPS Fabricius.

A widespread dominant genus, with numerous American species. Four
fossil species have been found in the older Kuropean Tertiaries, and one of
these is also recorded by Heer from Greenland.

A name proposed by Heer for fossil Cistelidze of uncertain position, of
which he described four, two from Greenland, the others from Baden and
from Sachelin in eastern Asia. E. Geinitz has used the same generic term

rugee. Body of the single specimen preserved on a side view so that it is
impossible to say how much broader the elytra are at their base than the
prothorax, but they have the appearance of being somewhat broader ; there
are faint signs on them of an exceedingly shallow, not very dense, and
uniform punctuation, and, in places, of short hairs arising from the puncta.
Legs very slender and constructed as in G. minimum Say.

Length, 6 mm.; breadth, 2 mm.

The form of the prothorax is very unlike Gnathium, but I find no
other genus to which it is so nearly allied at all other points.

Florissant, Colorado; one specimen, No. 7493.

RHIPIPHORID A.

Only four fossil species of this family are known, belonging to three
genera, all but one of them found in the Old World.

TOPOGRAPHIC MAP OF THE UNITED STATES.

When, in 1882, the Geological Survey was directed by law to make a geologic map of the United
States there was in existence no suitable topographic map to serve as a “hase ‘for the geologic map.
The preparation of such a topographic map was therefore immediately begun. Aboue one- filth of the
area of the country, excluding Alaska, has now been thus mapped. The imap is published in atlas
sheets, each sheet’ representing a small quadrangular district, as explained under the next head-
ing. ‘The separate sheets are sold at5 5 cents each when fewer than 100 copies are purchased, but when
they ees ordered in lots of 100 or more copies, whether of the same sheet or of different sheets, the
price is 2 cents each. The mapped areas are widely scattered, nearly every State being represented,
About 900 sheets have been engraved and printed; they are tabulated by States in the Survey’s
“List of Publications,” a pamphlet which may be had on application.

The map sheets represent a great variety of topographic features, aud with the aid of descriptive
text they can be used to illustrate topographic forms. This has led to the projection of an educational
series of topographic folios, for use wherever geography is taught in high schools, academies, and
colleges. Of this series the ‘first folio has been issued, viz:

1. Physiographic types, by Henry Gannett, 1898, folio, consisting of the following sheets and 4
pages of descriptive text: Margo (N. Dak.-Minn. y a region in youth; Charleston (W.Va.),a region in
maturity ; Caldwell (Kans.), aregion in old age; Palmyra (Va.), a rejuvenated region; Mount Shasta,
(Cal. ),a young voleanic mountain; Eagle (Wis ), moraines; Sun Prairie (\Wis.), drumlins; Donaldson-
ville (La. ), riv ‘er flood plains; Boothbay (Me. ), afiord coast; Atlantic City (N.J.), a barrier-beach coast.

2. Physiographic types, by Henry Gannett, 1900, folio, consisting of the following sheets and 11
pages of descriptive text: Norfolk (Va.-N. C.), a coast swamp; Marshall (Mo.), a graded river;
Lexington (Nebr.), an overloaded stream; Harrisburg (Pa.), Appalachian vidgeds Poteau Mountain
(Ark.-Ind, T.), Ozark ridges; Marshall (Ark.), Ozark Plateau; West Denver (Colo. ), hogbacks;
Mount Taylor (N. Mex.), voleanic peaks, plateaus, and necks; Cucamonga (Cal.), alluvial cones;
Crater Lake special (Oreg.), a crater.

GEOLOGIC ATLAS OF THE UNITED STATES.

The Geologic Atlas of the United States is the final form of publication of the topographic and
geologic maps. The atlas is issued in parts, progressively as the surveys are extended, and is designed
ultimately to cover the entire country.

Under the plan adopted the entire area of the countr y is divided into small rectangular districts
(designated quadrangles), bounded by certain meridians and parallels. The unit of survey is also the
unit of publication, and the maps and descriptions of each rectangular district are issued as a folio of
the Geologic Atlas.

Each folio contains topographic, geologic, economic, and structural maps, tozether with textual
descriptions and explanations, and is designated by the name of a principal town or of a prominent
natural feature within the district.

Two forms of issue have been adopted, a ‘library edition” and a ‘field cdition.” In both the
sheets are bound between heavy paper covers, but the library copies are permanently bound, while
the sheets and covers of the field copies are only temporarily wired together.

Under the law a copy of Gaia folio is sent to certain public libraries and educational institu-
tions. ‘The remainder are sold at 25 cents each, except such as contain an unusual amount of matter,
which are priced accordingly. Prepaymentis obligatory. The folios ready for distribution are listed
helow. ;
