The fact that two entire families of North American Coleop-
tera, although treated monographically in the present work, are
composed principally of species whose names now appear for the
first time in the annals of scientific literature, must be regretfully
regarded as proving the comparatively slight amount of interest
evinced in this country for the systematic study of entomology.
The study of nature in any sphere is ennobling and broaden-
ing to the mind, whether it concerns elementary matter or the
phj'sical forces which control the universe, the infusoria or the
mammals, the bacteria or those great trees which excite the ad-
miration of the most apathetic of us ; but, as we human beings
are primarily and essentially a social animal, it is evident that in
a general sense the opinion of the people at large must have some
weight in fashioning the tastes and predilections, even of those
in whom the thirst for disinterested research is especially devel-
oped. We can account in this wa}" for the exceedingly small pro-
portion of scientific men who regard the study of morphological
entomology as worthy of very serious consideration, although it
can scarcely be disputed that in the Insecta occur the most won-
derful structures to be found in the entire domain of nature, the
most singular adaptations, and the most prolific sources of data
to be ultimately utilized in attacking some of the apparently in-
scrutable problems of biological evolution.
Perhaps the day may arrive some centuries hence, when the
world shall have become more widely and more homogeneously
educated, when systematic workers in the field of entomology
can count themselves among the candidates for honors and dis-
tinctions, similar to those now bestowed by popular favor upon
him who discovers out in space a tiny point revolving about a
dash of light almost equally minute, or who, by mathematical

logic deduces the laws of planetary motion, or who. by patient
and careful weighing discovers a hitherto unknown constituent of
our atmosphere. These fields of scientific enijuiry are all parts of
one grand cosmos, and I cannot conceive one of tiiem to be more
soul-inspiring than another; they are all equally wonderful,
equally beautiful, and equally beyond the ken of Unite intellect.

This genus is represented in America l)y numerous species,
which, because of their comparatively constant and monotonous
facies, have gained the reputation of being a difficult lot to deal
with systematicalh- ; but this is by no means the case in reality.
There are several sclerites which are sutiiciently diversified to
afford most satisfactory taxonomic elements, and in fact the
species can be separated into two almost equal divisions, based
upon radically different types of epijileural structure Avhich can
be recognized upon mere cursory examination. The extent of
development of the long erect tactile seti\} of the al)domen, an-
tennal structure, sculpture of the elytra and ventral characters of
the male can also be employed advantageously in classification,
as these all difi!^er in a marked and sufficiently constant degree
among the various species ; the difference in elytral sculpture be-
tween lowxi, bipustulata and parvula, for example, is very pro-
nounced. In some cases I have resorted to peculiarities of color-
ation for the principal difl^'erential character of the species.
In the following table I have been compelled to add a number
of new species to those already known, and to correct some very
inaccurate and misleading synonymv which has been allowed to
stand in our recent lists : —
I. Epipleuni' broader, siililioiizontal, iniliesceiit, impressed toward hase, birt
witli the outer inarjiin only descendinu slightly below the inner.

Whenever possible the descriptions which follow are drawn
from the male.
The measurements of length refer to the head and body as far
as the extremit}^ of the elytra, the abdomen being wholly excluded.

Moderateh' broad, testaceous, the head and apical half of the
pi'onotum, elytra externally and toward apex and abdomen in
about apical half, black ; antennre blackish but testaceous toward
apex and base. Head nearly one-half as wide as the prothorax,
minutel}' punctulate, extremely minutely and feebly substrigilate,
the antennae long, feebly incrassate, the tenth joint in the male but
slightly longer than wide, the eleventh one-half longer than wide
and acutely and s^'mmetrically pointed. Prothorax three-fifths
wider than long, the apex about three-fifths as wide as the base,
minutely, very closely and rather distinctl}" punctulate, the sur-
face extremely minutely and transversely substrigilate. Elytra
nearly as long as wide, only slightly narrowed from the base, with
the sides evenly and feebly arcuate, slightly narrower than the
prothorax, the external apical angles right and but little rounded ;
apex very feebly, triangularly' emarginate; disk rather depressed
and finely, excessivel}^ densely punctulate, extremely minutel}'^
and densely pubescent. Abdomen rapidly conical, the black
seta? short and inconspicuous toward base. Length 2.25 mm.;

Pennsylvania to Wisconsin (Bayfield, Lake Superior). The
male has a large triangular emargination at the apex of the
sixth ventral segment, the angle of which is rather broadly
rounded. In this distinct species the elytral sculpture and ves-
titure are more minute and dense than in anj- other known to me.

Europe and Massachusetts. The sixth ventral of the male has
a very large triangular emargination nearl}- as in knoxi, but with
Goleopterological Notices, VI. 439
the angle less rounded, and the elytral sculpture is extremely
finely and closely imbricato-punctulate, almost as densel}' as in
Inoxi. As in that species, the epipleurae are A-ery wide, nearh'
flat, subhorizontal, densely pubescent and punctulate throughout
and broadly, feebl}' impressed in the middle toward base. I am
of the opinion that the few examples of this species thus far
taken in the United States are mere sporadic importations.

liead and i)ronotnm exceedingly minute and occupied almost en-
tirely l)y the base of the hairs. Head one-half as wide as the pro-
thorax, the antenn:\; rather long, gradually and evenly incrassate
through the last six or seven joints, the penultimate slightly
wider than long. Prothorax nearly- one-half wider than long, the
basal angles rather al)ruptly prominent posteriorly-, right and not
distinctly rounded. Elytra not quite as long as wide, somewhat
distinctly longer than the prothorax, perceptibly narrowed from
the base, with the sides ver3^ feebly but evenly arcuate, the
disk strongly convex, perfectly even in coloration, somewhat
coarsely and feebly imbricate and minutely, ver}^ densely pubes-
cent. Abdomen quite evenly tapering from base to tip, the erect
set{\3 short and inconspicuous except at the apex. Length 2.0-
2.25 mm.; width 1 15-1.3 mm.
New York, New Jersey and Pennsylvania. The male has a
feeble rounded median sinuation at the apex of the fifth ventral,
the sixth having a deep rounded sinuation at the middle, about
three times as wide as deep and with the external angles very
broadly arcuate. The epipleurte are wide, punctulate and pu-
bescent throughout, subhorizontal and l)roadly impressed in
about basal half.
This species is allied to the European pubescens, but is more
convex, with more gradually incrassate antennaa, and differs also
in coloration and decidedl}^ in sculpture. In puhescens Payk.,
of which I have before me a series carefully determined by Mr.
Reitter, the elytra are smaller and more depressed, and are gener-
ally rufous with the suture and flanks blackish ; the antenna? are
much more rapidly and strongly incrassate through the outer five
joints, and the penultimate joints are fully as long as wide; the
sinuation of the fifth ventral is much wider and the rounded notch
of the sixth narrower, not more than twice as wide as deep, with
the external angles much less broadl3' rounded. In the European
species the elytral sculpture is very much finer, denser and less
distinctly imbricate, this being noticeable in all the numerous
specimens compared, even under the low powers of the hand lens.
The recentlv published lists of Coleoptera common to Europe
and America have in several cases been carried much too far, and
numerous instances occur, especiallj- in the Staphylinid.t?, where
species closely allied by reason of community of descent have
been regarded as identical ; in some cases the species which have
Coleopterological Notices, VI. 441
been thought to be identical are not even particularly closel}' re-
lated to each other. Tiiese mistakes principally refer to the fauna
of eastern North America, the proportion of common forms of the
west coast being much greater. In fact, if we omit the well
known cosmopolitan species and those which have been sporadi-
cally and locally introduced, the fauna of eastern America in-
cludes but a very small actual number of species identical with
their homologues of Europe, and there is no good reason why the
term "'Nearctic" should not be employed for this region, in con-
tradistinction to " Pahijarctic," which includes Europe, northern
Asia and the west coast of North America. The large number of
identical genera and closel}- allied species in the ISearctic and
Palnearctic faunas shows plainly that they have a common origin,
but there can be no doubt that the}' are now sufficiently differen-
tiated to warrant a continuation of the distinctive appellations.
5. C liillllloides ii. sp. — Suhoval, strongly convex, mocleratelj' shining-,
blackish throughout, the apices of the ventral segments slightly paler; legs
pale testaceous, the posterior darker; autennie iufuscate toward the middle;
pitbesceuce moderately fine, dense and decumbent, dark in color; j)unctures
of the head and prouotum extremely fine, occupied by the base of the hairs ;
those of the elytra not distinct. Head barely one-half as wide as the prothorax,
the epistoma only moderately transverse; antennae extending slightly beyond
the base of the prothorax, very stout and gradually incrassate, the penultimate
joints rather strongly transverse. Prothornx rather elongate, not more than
two-fifths wider than long, the .apex about three-fifths as wide as the base;
sides evenly arcuate; basal angles moderatel}' and not very abruptly promi-
nent posteriorly, slightly more than right and not much rounded. Scutellum
large, triangular, slightly wider than long, with the sides very feebly arcuate
and the apex scarcely at all blunt. Ehjtra not quite as long as wide and but
slightly longer than the prothorax, the sides scarcely visibly convergent from
base to apex and extremely feebly but evenly arcuate; apex very feebly
angulato-emarginate; disk, rather coarsely imbricate, the imbrications feebly
reticulate. Abdomen gradually tapering, the settle very short, sparse and in-
conspicuous except at apex. Length 1.8 mm. ; width 1.2 mm.
Iowa.
Readily distinguishable from the preceding, which it strongly
resembles in habitus, by the sexual characters of the male, the hfth
ventral being completely unmodified and the sixth having a broad
shallow apical sinuation, rounded at the bottom and four or five
times as wide as deep ; it also dirters in its shorter antennjc, with
the outer joints much more transverse. The epipleura' are nearl}-
flat throughout, being fee'ily imi)ressed only near the base. Three
specimens.

6. C. velocipes n. sp. — Moderately stout, strongly convex, feel>ly shin-
ing, blaokish, the basal niarjiins of the pronotuni and elytra unevenly and
feebly suffused with a paler reddish tint: abdomen paler, red-brown through-
out; legs and antenna- rufo-testaeeous, the latter paler and more yellowish
toward base and at the eleventh joint; jjubescence very fine, dense and plum-
beo-cinereous throughout, the punctures minute and scarcely visible. Head
small, distinctly less than one-half as wide as the prothorax, the epistoma
paler and with more distinct punctulation and reticulation; antenna; rather
long, evenly and gradually incrassate througli the last six or seven joints; the
ninth scarcely as long as wide, the tenth perceptibly wider than long, eleventh
rather short, somewhat rapidly, obliquely and acutely pointed at apex.
Prothorax nearly three-fifths wider than long, the apex but slightly more than
one-half as Avide as the base, the sides evenly and strongly arcuate becoming
l)arallel toward base, the basal angles gradually and only moderately promi-
nent posteriorly and distinctly rounded. Eli/tra nearly one-fourth wider than
long, not at all longer than the i)rothorax, the sides distinctly convergent but
only very slightly arcuate from base to apex; disk convex, moderately finely
imbric<ate. Abdomen very evenly and gradually tapering from base to apex,
the erect black seta; long and distinct at the sides throughout, but, as usual,
ICvSs numerous toward base. Length 2.0 mm. ; Avidth 1.4 mm.
New York (near the city); New Jersey; Virginia (Fredericks-
burg).
This distinct species may be readily known by the ventral
sexual characters of the male, the long black and bristling setiie
being ver}-^ numerous throughout, except broadly along the
median line where the ordinary short pale pubescence becomes
longer, more erect and conspicuous. The sixth ventral has a
triangular nick in median third at apex, the notch nearly three
times as wide as deep and with the angle not rounded, the apex
of the fifth segment arcuately sinuate in the middle. The epi-
pleuriv are wide and l>ecome gradually nearly glabrous toward
base. This species may be distinguished from imhricata l»y its
shorter elytra and long black bristles toward the base of the
abdomen.

Coast regions of California from Humboldt to Los Angeles ; I
obtained three specimens also at Lake Tahoe, which represent a
slightly smaller and narrower variety. The male has a rounded

sinuation at the apex of the sixth ventral, occupying about median
third and about tliree times as wide as deep, and the apical mar-
gin of the fifth segment is very feebly- sinuate in the middle. The
epipleurffi are wide, pubescent throughout and broadly, feebly im-
pressed toward base. A female specimen, taken near Monterej-
Bay, is blackish throughout but does not seem to differ materiall3'
otherwise.
8. C'. virgiiiiae ii. sp. — Stout, strongly convex, feebly sTiiniiig, the pu-
bescence fine, very dense and pluniljeo-cinereous throughout, the punctures
scarcely visible ; body pale brownish -testaceous in color, the legs concolorous;
antennae brown, paler and diaphanous toward base, the eleventh joint also
pale. Head small, scarcely two-fifths as wide as the prothorax, the antennse
rather long, very evenly and gradually incrassate through the seven outer
joints, the ninth slightly elongate, the tenth a little wider than long, eleventh
scarcely one-half longer than Avide, almost symmetrically and rapidly pointed
at apex. Frothorax one-half wider than long, strongly convex, the sides
strongly and evenly arcnate, l^ecoming parallel toward base; the apex but
slightly more than one-half as wide as the base, the basal angles gradually
and strongly prominent posteriorly, right and slightly blunt. Elytra a little
narrower and but very slightly longer than the prothorax, not quite as long as
wide, the sides distinctly convergent and broadly arcuate from base to apex,
the latter broadly and triangularly eniarginate; disk somewhat coarsely but
feebly imbricato-punctulate. Abdomen gradually tapering from the base, the

Virginia (Norfolk).
In the male the sixth ventral has a triangular notch occupying
about median third of the apex and about twice as wide as deep,
with the angle scarcely at all rounded and the sides nearl^^
straight, and the fifth segment is feebly sinuate in the middle of
the apical margin. The epipleura? are moderately wide, deeply
hollowed in more than basal half, pubescent but becoming gradu-
all}' glabrous near the base. A single specimen.
9. C niacer n. sp. — leather narrow, strongly convex, feebly shining, pale
brownish-testaceous tln-oughout, the legs and antennte concolorous, the latter
more flavate at apex and toward base as usual ; pubescence very dense, rather
dark in color. Head nearly one-half as wide as the prothorax, the antenna)
moderately long, evenly but rather rapidly incrassate through the five or six
outer joints, the seventh elongate, the ninth and tenth somewhat wider than
long, eleventh oval, stout and very obliquely i»inted at apex. Prothorax fully
one-half wider than long, the apex two-thirds as wide as the 1)ase; sides
evenly and strongly arcuate; basal angles gradually and strongly prominent
posteriorly, right and ouly slightly hlnnt. Ehjira short and transverse, nearly

South Carolina,; Virginia (Xorfollv).
The male above described has the tip of the sixth ventral
emarginate throughout tlie widtli, the notch broadly trianguhxr,
and about three times as wide as deep, with the sides feebly arcu-
ate and the angle narrowly rounded ; the fifth ventral is com-

Europe, eastward through Asia and along the western coast of
North America to the mountains of California. This species
is remarkable in having no trace of imbricate sculpture on the
elytra and in fVict this sculpture, which is universal in the
American species of the preceding group, is frequently sub-
obsolete in this section of the genus ; in the present species the
surface is finely punctulate and minutely and transversely stri-
gilato-reticulate. The epipleurse become vertical externally to-
ward base and are glabrous, with the exception of a few hairs
along the inner marginal bead ; the}' do not quite attain the
elytral apex and the external angles of the elytra are rounded.
The basal angles of the prothorax are only feebly produced pos-
teriorly and are rounded.

becoming parallel at the base, the basal angles rather strongly
prominent posteriorly but distinctl}- rounded. Elytra slightly
wider than long, equal in length to the prothorax ; distinctly

New York to Iowa and Texas. A small and widely distributed
species, varying but little in the large series before me. The
male has a large and broadly rounded emargination occupying the
entire apex of the sixth ventral segment, the fifth being com-
pletely unmodified at the apical margin. The epipleurffi are
narrow and do not quite attain the rounded apical angles; they
became vertical toward base externally and are practicall}- glab-
rous throughout.
In assigning setifer to opica Say, as a synonym. Dr. Horn
entirely neglected to observe the long bristling setfe throughout
the length of the abdomen, which would have shown him its true
position at once, irrespective of the radically difi'erent form of
the epipleurffi.

District of Columbia and Massachusetts. This is an isolated
species, in no way closel}^ related to basalis, differing in its larger
size, more transverse and much less conical prothorax, and in its
longer and sparser pubescence. It difters most radicall}-, however,
in tlie male sexual characters, the fifth ventral in that sex being
broadly sinuate in more than median two-thirds ; the sinuation
rounded and about ten times as wide as deep, the sixth segment
having a deep rounded sinuation in about median third. The
epipleurie are rather narrow but extend to the elytralapex, gradu-
ally vertical externally towards base, glabrous but with a few
sparse hairs posteriorly. The two specimens from the last named
localit}', since received, do not diflfer in any way from the original
female tyi)e from the District of Columbia.

New York and North Carolina (Asheville) to Wisconsin (Bay-
field). This is a common and widel}' distributed species of large
size,beingmuch the largest American representative of the genus.
The male has the fifth ventral perfectlv simple at apex, the sixth
having a ver}' large and deep, almost circularly rounded emargina-
tion, and there are numerous long black setfe on the abdomen
beneath and at the sides as far as the base. The epipleur;^^ are
very narrow, attenuate behind, not attaining the elytral apex,
glabrous and polished throughout and becoming strongly vertical
toward base. The elytral sculpture is not imbricate, each of the

On attentive observation the strnctural differences among the

are, as before remarked, ver}- radical indeed, in spite of the gen-

Pennsylvania (near Philadelphia). This species is allied to
crassa, but is evidently distinct. It is very much smaller than
any examy)le of a verj^ lai'ge series of crassa which I have before
me, and differs in antennal structure to a marked and perfectly
decisive degree, this organ being much more rapidly and strongly
incrassate, the tenth joint not or scarcely longer than wide and
the eleventh very much shorter than in crassa, where its elongate
form constitutes one of the principal distinctive features of the
species in both sexes. It differs, besides, in the much narrower
epistoma. It is still represented by the unique female type.
In the original description of both this species and occulta, I
have obviously underestimated the width of the prothorax in
terms of its length, the deception in relative proportion when
measured by the eye not having occurred to me at that time.

abdomen. The epipleurje are narrow, entire, and only slightlv

TRO<;OPIII><ElTS Mann.
The species allied to fimidarUis constitute a small group in
which the sexual differences in bodily form and habitus become
extreme, the male being very much stouter than the female and
with the head and prothorax conspicuously larger. The three
known to me ma^' be distinguished as follows by the males : —
Eyes large, at nnicli less tlian their own length from the prothorax; pronotum
finely and extremely densely pnnctate, -with a very narrow impunctate
median line.
Sides of tlie jtrothorax parallel in apical half siinplarillS Lee.
Sides of the prothorax convergent from the middle to the apex ( falhix Csy. 9 )
pallid iiliis Csy.
Eyes small, at their o\\n length from the base; pronotum finely' and sparsely
punctate toward the middle, with a broad impunctate median area.
salicola n. sp.
The eyes are of about the same size in both sexes, and are
therefore larger in proportion to the size of the head in the female
than in the male. The inner apical angles of the elytra are nar-
rowly rounded.
T. salicola. — Very stout, parallel, rather convex, somewhat shining,
deep black throughout; antenna; piceous; legs black, the X\hvx. toward base and
apex and tarsi paler; puliescence fine, very short and dense but dark in color
and only moderately conspicuous. i7«(// triangular, as wide as long, impressed
within the antennal prominences, finely punctate, sparsely so toward the mid-
dle, more densely scabro-reticulate and dull toward the sides ; antennse moder-
ate in length, the second joint as long as the next two; basal joint elongate
and contorted. Prothorax distinctly wider than the head, two-fifths wider
than long, the sides subparalltl and feebly arcuate in apical half, strongly con-
vergent from the middle to the base, the latter scarcely more than two-thirds
as wide as the apex, which is broadly, evenly arcuate; disk almost even, with
scarcely a trace of impressions. Etytra distinctly wider than long, two-fifths
longer and a little wider than the prothorax, impressed at each side of the
suture toward base, finely, closely punctate and somewhat scabriculate. Ab-
domen slightly narrower than the elytra, the sides parallel and feebly arcuate,
the sirrface coarsely and strongly reticulate, fineh', not densely punctate and
clothed moderately densely with longer and stiller pubescence. Length 2.8
mm. ; width 0.7-0.8 mm.
Utah (Great Salt Lake). Hubbard and Scliwarz.
Coleoj^ferological Notices, VI. 451
The description, except the measurements, refers to the male,
the female being much narrower, the prothorax apparently having
but slighth' more than one-half the bulk, with the sides more con-
vergent in apical half, the disk more densely punctate and the
Avide impunctate line better defined.
It is probable that these three species are descended from a com-
mon ancestor, inhabiting the regions east of the Rocky Moun-
tains at the time when the Great Salt Lake basin was occupied
by a large body of fresh water ; as this lake retreated and became
more and more saline, salicola became correspondingly different
from the types represented b}^ simplarius and pallidulus.
CUCUJID.E.
MURMIDIIN/E.
Another new genus, very different from anj^ previously known,
but apparently assignable to this isolated group of monotj'pic
genera, has recently been discovered, and the genus Mychocerus,
which was unknown to me in natui'e when I last referred to the
subject (Col. Not. II., p. 321), is now amply represented before
me. With this new material, it becomes sufficiently evident that
greater weight must be given these interesting structural types
than I previously supposed, and, instead of constituting a mere
tribe of Colydiina?, it is prol)able that they should more properly
form a group subequivalent in value to the Coljdiidfe, if we view
the latter as a family, or to the Col^'diinte, if we consider these a
subfamily' of the Cucujidoe, as formerly suggested by the writer
(Col. Not., II., p. 49G). This course is also in harmony with the
views of DuVal, who proposed a distinct family for Murmidius.
The new genus, referred to above, differs very greatly from all
the others in having the fourth joint of the maxillary palpi cylin-
drical and elongate, fully as wide as the preceding and affixed
closely to its apex throughout the width ; but the anterior coxie
are small, globular, and have their cavities widely open behind
and closed by the mesosternum. It also differs in not having an-
tennal fossae; but the agreement in many respects is such as to
strongly suggest the Murmidius group of genera as its nearest
allies. The present opportunity may also be taken to correct a
serious error, quoted from the books in my previous work, in
Annals N. Y. Acad. Sci., VIII., July, 1895.— 32
452 Goleopterological Notices^ VI.
regard to Mycliocerus, the legs in that genus being perfectly free
and not retractile.
The principal distinctive features of the Murniidiinfo are the
very small oval body, the widely separated coxaj. the somewhat
elongate basal segment of the abdomen, the ten-jointed antennae
and the small deei) coxal cavities, closed behind by the ineso-
sternum, although I have not examined the Colydiint\? very thor-
oughly for the purpose of determining the weight of the latter
character as a distinguishing feature.
The four tribes may be briefly characterized as follows: —
Antennal cavities present: last joint of the maxillary palpi slender and aeicu-
late.
The cavities large, shallow and completely on the under surface; labrum
triangular, with the apex acutely incised; legs partially retractile; pro-
sternal lobe short Lapethiki
The cavities at the apical angles of the prothorax, visible in front but not
from above; labrum short and transverse; legs free; prosternal lobe not
concealing the trophi in repose M YCHOCERixi
The cavities at the apical angles and Avholly visible from above; lal)rum
probably very short and transverse; legs strongly retractile; prosternal
lobe large, completely concealing the labrum and mouth parts in repose.
MURMIDIIXI
Antennal cavities wanting ; last joint of the maxillary palpi elongate and as wide
as the preceding; labrum truncate; prosternal lobe short; legs free; anterior
coxae much less widely separated EupsiLOBllNl
In Cerj'lon the anterior coxal cavities are completely' closed be-
hind by the broad fusion of the propleura? and intercoxal pro-
cess, but in Pliilothermus the cavities are open behind. Philo-
thermus will therefore form a distinct tribe uniting the Mur-
midiinai with the Colydiini\i through the Cerylonini, and might
be provisionall}' attached to the former; in general facies it is
strikingly intermediate between Cerylon and Lapethus. The
mentum in Pliilothermus is slightly elongate-oval, with a strong
elevation in the form of an acute triangle, and the 11-jointed anten-
nne have a strong 2-jointed club, the joints being perfectly free.
Lapethini.
This tribe consists at present of the single genus Lapethus
(Col. Not., II., p. 317), having the prosternal process rather long,
broadly rounded at ai)ex and received, on nearly a common level,
in a broad emargination of the mesosternum ; prosternum verv
Coleopterological Notices, VI- 453
widel}' separating the coxt\? and without elevated lines, the ante-
rior lobe short and not concealing the mouth parts. Antennal
excavations large and inferior, the antennte ten-jointed, with the
two basal joints large, the third elongate, the club large, oval,
compressed and composed of three closely amalgamated joints,
as indicated by the pubescent rings. Elytra seriately punctate,
the epipleura^ excavated at base. Met-episterna long, narrow^
gradually wider anteriorly and a little more strongly dilated pos-
teriorl}-, the suture fine, the surface punctate ; met-epimera obso-
lete. Mentum elongate, well developed and strongly carinate
along the median line.
Dr. Sharp, in the " Biologia," has regarded some Mexican ex-
amples as conspecific with L. discretus, hut considering the habits
of this species, and the fact that members of the true Pacific coast
fauna seldom extend into Mexico, it is possible that thej' may iu
reality represent an allied but distinct species.
Mychocerini.
In this tribe the prosternal lobe is short, broadly truncate and
does not conceal the trophi in repose, the mentum very minute,
the fourth palpal joint slender and as long as the third; antennte
with the two basal joints large, the club small, solid, scarcely at
all compressed, cylindro-ovoidal, obtuse at apex and apparently
composed of two completely amalgamated joints, the second
forming the more densely pubescent terminal portion. Antennal
cavities small, deep, apical and not visible from above. Labrum
shoi't and broadly rounded, the epistoma ver3' large, with the
suture fine but distinct. Met-episterna very narrow, the suture
fine but more visible than in Murmidius. Legs completely' free,
the epipleuroe not at all excaA'ated.
The two genera ma}- be distinguished as follows: —
Prosternum flat, with two distant and parallel ridges not attaining the apex,
the process very short and Ijroad, abutting on a common level with the nie-
sosternum along a transversely rectilinear line; elytra seriately punctate;
body depressed ]fly clioc'e I'US
Prosternum transversely convex, with two very tine, distant, elevated and an-
teriorly diverging lines not quite attsiining the apex, the process very short,
extending under th,e advanced and rounded beaded lobe of the mesoster-
num; elytra without trace of serial punctures, the body much more elon-
gate-oval and convex Botrodiis
454 Goleopterological Notices, VI.
In Botrodiis the fifth and sixth joints of the antennj\3 are ap-
parently slightly dilated. The t^-pe and only species of Mycho-
cerns known to me is 31. (lepressus Lee, which occurs rarely in
the District of Columbia and in Ohio. B<AroduH estriatus Cs}'.
occurs in Texas. The species recently described from Mexico
by Mr. Lewis I have not seen.
MURMIDIINI.
The small and possibly cosmopolitan species known under the
name Murmidius oralis Beck., ditters profoundly from the two
preceding genera in a number of structural features, and demands
a distinct tribe. The prosternum has two strongly elevated par-
allel lines not attaining the apex, the anterior lobe being very
large, rounded, evenl}^ continuous with the sides of the prothorax
and completely concealing all the mouth parts and labrum in re-
pose; intercoxal process short and broad, extending under the
broad and advanced mesosternal process. Antennal cavities small,
deep, apical, superior and completelj' visible only from above.
Epistoma verj- large, the suture fine. Legs stronglj- i-etractile,
the epipleume with a deep crural excavation at base and another
near the middle. Met-episterna extremely narrow but not con-
cealed by the epipleurae, the suture verj- fine and feeble. El3tra
seriately punctate.
I am unable to observe tlie labrum, trophi or antennae in the
three specimens in m^' cabinet.
EUPSILOBIINI.
The general characters of this tribe are included in the follow-
ing description of the onl}^ genus thus far discovered : —

with the fourth joint long, c^dindrical, obtusely pointed, as wide
as the third and longer than the three basal joints combined ;
labial palpi shorter but much stouter, the second joint transverse,
the third broad, oval and compressed. Ligula large, broad, cor-

ing month parts not clearly visible in the t^'pe. Mandibles small.
Labrum short, transverse, trnncate, the epistoma short and small,
with the sutnre fine. Eyes small and coarsely faceted. Antenna?
moderately developed, ten-jointed, the first two moderately' large
and subeqnal, the following six small, narrow, compactl}' joined,
the funicle bent at its middle point ; club very abrupt, rather
large, broad, only slightl}- longer than wide, oval, strongly com-
pressed, composed of two joints which are apparently free but
closely joined, the first transversely lunate and wider than the
second, the latter transverse!}' oval, fitting in the hollow of the
first; antennte not received in excavations except the funicle,
which may be received in the deep cleft separating the prosternal
lobe from the hypomera. Prosternum small, without raised lines,
rather narrow between the coxpe,the latter separated by less than
their own width, their small and c^eep cavities closed behind by
the raesosternum, the process very short, extending partially
under the broad and slightly advanced, rounded and finely beaded
mesosternal lobe ; apical lobe short, truncate and only partially
concealing the mouth parts in repose. Middle coxa^ widely, the
posterior ver^- remotely separated. Metasternum and first ven-
tral segment with very feeble oblique coxal lines; met-episterna
moderately narrow, long and "parallel. Abdomen composed of
five segments, the last four short and subeqnal, the first nearly
as long as the next three combined ; sutures perfectly rectilinear
from side to side. Legs short, complete!}^ free, the femora stout,
oval, partially receiving the tibise, the latter short, sublaminate
and rounded externally ; tarsi moderate in length, four-jointed,
the three basal joints short; claws small, slender and arcuate;
trochanters laminate. Epipleuroe moderate in width, flat, horizon-
tal, gradually and finely attenuate behind, the outer margin de-
scending very slightl}' l)elow the level of the inner at the base.
The advancement of a rounded and beaded mesosternal lobe is
a character peculiarly distinctive of the Phalacridiv, and the gen-
eral habitus of the body in the present genus also suggests that
family, but the reseml:)lance goes no further.

It is probable that this species will prove to be widely distrib-
uted through the West Indies, and by no means confined to the
small sand}^ islet near Key West. I have before me a single
rather ill-conditioned specimen.
MELYRID.E.
After careful study of the considerable material in ni}- cabinet,
I can see no cause to doubt the soundness of Motschulsky's
opinion (Bull. Mosc, 1859, p. 388) that the melyrides should con-
stitute a family distinct from the Malachiidffi; their entire habitus
is different, and the most important of the special peculiarities of
the Malachiid}>?, viz., the extensible vesicles, is completely un-
known among them ; their integuments, furthermore, are hard and
thick, and resemble those of the Cleridie rather than the Mala-
chiidiB. The Melyridj\^ constitute a moderately large family,
which is so homogeneous that it is ditlicult to find man\' valid
characters to define even the genera, and the groups higher than
genera are ver}'^ few in number. The species are exceedingly
abundant west of the 100th meridian, and increase in number and
variet}' to the westward, following the same law as the Hetero-
mera, except that they are relatively more abundant perhaps in
the true Pacific coast fauna. The famil}' is essentially subarctic,
and is ver^- poorh' represented south of our Mexican boundary.
It is not necessary to allude in the present preliminary essay to
the general structural details of the famil}^ as these are given
with sufi[icient fullness in many systematic works, and also be-
cause all those structures which, by reason of diversification ap-
parently afiord eflScient means of grouping the species, are men-
Goleopterological Notices, VI. 45T
tioned in the tables given below or in the notes under the various
generic headings. It should be stated, however, that the reason
for the enormous proportion of new species here proposed, is to
be found in the fact that the famil}^ has been almost totally neg-
lected by systematists in this country for about thirty years,
and that at the date of the last S3'nopsis b}" LeConte, the extreme
western country, where these forms particularly abound, had been
scarcely explored in even a superficial manner. A very large
number of new species will still have to be described by future
investigators, for, at the present time every collection, however
small, made in those regions with their numerous local faunas, is
made up to a considerable extent of nondescripts.
The ]Mel3'rid;\^ maj- be divided into two very unequal subfam-
ilies, as follows : —
Maxillary palpi cylimhical, the fourth joint pointed; eyes finely faceted and
nude; tarsi with short stiff and inconspicuous hairs beneath Melyrin^e
Maxillary palpi longer and much more developed, with the last joint
large and triangular; eyes very coarsely faceted and setose; tarsi with long
dense hairs beneath Rhadalin^
The second of these subfamilies is composed at present of only
two species, constituting the genus Rhadalus of LeConte, while
the first probably numbers several hundred in the United States
alone.
MelyriiN.e.
The Melyrini\} can be divided into two tribes, which however
possess rather less than the usual tribal weight, as follows : —
Basal joint of the tarsi longer than the second, the tarsal claws generally
appendiculate Dasytini
Basal joint slightly shorter tlian the second; tarsal claws not appendiculate.
Melyrini
Dasytini.
In distributing the multitudinous species of this tribe among
numerous genera, the principal taxonomic elements employed re-
fer, first, to the form, extent and position of the elytral epipleuraj,
their plane being either horizontal, reflexed or inflexed, that is
turned upward externally or internally respectively; secondly, to
the extent and conformation of the submembrauous ungual ap-
pendages, and thirdly, to the presence or absence of external
spines on the anterior tiljiic Other characters are occasionally

This grouping is not altogether satisfactoiy, because of the
proportionally large number of species comprised in only two or
three of the twenty genera, and also for the reason that several of
the genera now represented by single species have no A-ery great
individuality of habitus, and are to be distinguished b^- not more
than one or two really radical differential characters ; but I am
unable to devise a more consistent or natural classification at the
present time.
PRISTOSCEI.IS Lee.
The species described by LeConte under the name Prititoscelis
f/7-a)uJiceps, offers so many points of divergence from the tA'pical
forms of Trichochrous that we are compelled to suggest its gen-
eric isolation. The epistoma, for example, is wholly obsolete,
the apical margin of the front being finely beaded continuous!}-
from side to side; the laljrum is relatively very small and strongl}-
transverse, and the mandibles long and stout, the eyes small,
prominent and very distant from the base, and the ei)ipleurai nar-
row but horizontal, the edges of the elj'tra being distincth" re-
flexed. The ungual appendages are as long as the claws and sub-
equal, but the inner is detached from the claw through outer third
of its leno-th.

ErDASYTES n. gen.
The three species which it seems advisable to separate from
Tricliochrous under this name, do not form a very distinctly
characterized genus, and differ only in having the epipleura?
rather wide, flat and horizontal, and the lateral margins of the
el3tra narrowly- reflexed, this being a consequence of the epipleu-
ral structure. Still, if we regard epipleural structure as one of
the few important taxonomic elements in this tribe, it will cer-
tainl}' be necessary to form of these species a genus different from
Tricliochrous, and, after all, when we compare the structure of
C<Aeopterolo[iiral Notices, VI. 461
the tliorncic apex with the same part in Cradytes, where the
apical angles so prominent here are completelj' obliterated and
rounded, and the central portion of the apex correspondingly ad-
vanced, it would seem impossible to retain them all in the same
generic group. The prominent apical angles of Eudasytes reap-
pear feebly, however, in certain species of Trichochrous, and, in
Eudasytes ursinus these angles are rounded and but slighth' ad-
vanced; but, from the standpoint of epipleural structure, this spe-
cies would have to form a subgenus of Eudasytes, showing that
there may really be some correlation between the structure of the
epipleurae and form of the apical angles, at least in this particular
genus.
The three species differ much among themselves and may be
readily known as follows : —
Vestitiire pale; apical angles of the protliorax strongly advanced and not or
scarcely rounded ; epipleurte remaining horizontal to the extreme apex ;
legs pale.
Basal angles of the protliorax not prominent; erect sette of the elyti-a very
short; body much broader 1 ampllis
Bas;il angles laterally prominent ; erect setai long; body more elongate.

Vestiture blackisli; apical angles feebly produced anteriorly and rounded;
plane of the epi pleura? indexed toward apex; legs black 3 iirsiiius
As far as known the species are distributed through the arid
region extending from Utah to southern California, and probably
do not occur in the true Pacific coast fauna.

The description refers to a single female type from an unre-
corded part of the State. The epipleunv are rather wide, sub-
horizontal, polished and impunctate, becoming iuAvardly arcuate
at tip and vanishing only at the beginning of the rounded apical
angles. It is probable that the male will be found to ditier con-
siderably in general form.

This species may be recognized by its black color and long
hispid black setae. The description is drawn from the male, in
which sex the fifth ventral is but little longer than the fourth,
slightly trapezoidal and truncate at apex. The female differs
onl}^ slightly, the elytra being fully three-fifths longer than wide
and somewhat wider than the prothorax, the sides of the latter
more arcuate; the head is fully as large or even somewhat larger,
when compared with the [)rothorax, in the female than in the
male. Two specimens.
The epipleuriij are flat and horizontal, and, at the apex, have
their plane turned somewhat inward and upward.

ASV0.4TES n. gen.
This genus dirters but slightly from Trichochrous. but the
smull prothomx and broad subdepressed el^'tra, which are nar-
rowl}^ reflexed at the sides, give to the two species which at pres-
ent compose it, a facies which is quite peculiar and distinctive ;
the general habitus is in fact intermediate in some respects be-
tween Trichochrous and the genera allied to Allonyx. The epi-
pleuraj are broad and Hat, and this character distinguishes it at
once from Trichochrous, although in other structural features it
is virtually similar. The epipleur;\? are relatively altogether as
as wide as in Eudasytes, or even wider; the\' do not, however,
follow the apical curve of the elytra as in that genus, but become
abruptl}' obsolete at a greater distance from the apex. The spe-
cies are mutualh^ verA' distinct in appearance and ma}- be thus
distinguished : —
Pubescence coarse aud rather dense, not intermingled AWtli erect hairs; abdomen
entirely red 1 ruflreiitris
Pubescence fine and very sparse, intermixed with short but inconspicuous
erect hairs; abdomen red, blackish near the base 2 explaiiatiis
It is probable that this genus is local and confined to the coast
regions of California near Santa Barbara and Los Angeles, a
faunal region which is known to support a considerable propor-
tion of endemic forms.

TRIC ]IO( IIKOUS Motsch.
Itijturo.somus ; Emmenotarsus Mots; Pristoscelis l^ec. (pars.).
Within the broad compass which we are compelled to give it,
this genus is in all probability one of the largest of the North
American Coleoptera, its species occurring in unnumbered scores
in the extreme western regions of the continent, and especiall}- in
California, where it constitutes one of the chief arboreal elements
of the order. Its species differ much among themselves in size
and vestiture, but agree in having the appendages of the tarsal
claws well developed, equal, as long as the claws and attached to
them except in outer third or fourth of their length ; these ap-
pendages are of a gelatino-membranous texture, and subject to
malformation or distortion which is frequentl}' deceptive and
misleading, especially under low powers of amplification. The
species may be distinguished from Eudasytes and Asj^lates by
the structnre of the epipleurai, and from Listrus and its allies by
having the outer surftice of the anterior tibi^t — and of the others
to a less extent — beset with an irregular and partially double se-
ries of short stiff and widely spaced spinules. The bod}' maj- be
simply pubescent or have erect setae in addition, and may have a
dense thoracic fringe of short cilia as in Listrus; this regular
fringe is however generally wanting in those species which bristle
with long erect seta\
The sexual characters are usually quite distinct though only
rarely ver}' radical, but the sexes are nearly alwa^^s readil}^ differ-
ential)le. The male as a ruje has the head, and less frequently the
prothorax, larger, the antennre longer, and the elytra relatively'
shorter than the female. The abdominal characters are generally
feeble, the fifth ventral in the male being more or less evenl}''
truncate, but in a singular exception described below under the
name sexualis, this segment becomes strongly modified, an ex-
ception quite as pronounced as that of Cistela brevis when com-
ColeopteroJofjical Notices, VI. 46T
pared with C. theveneti (Col. Xot. III., p. 163). The third and
fourth segments in the males of certain small species with pale
elytra have a cluster of short radiating spinules in the middle.
The genital segment varies but little; it is generally emarginate
in the male and more or less truncate in the female, and is im-
pressed along the middle in both sexes. Beyond the genital seg-
ment the under part of the dorsal pygidium gives the appearance
of still another terminal segment; this inferior surface is more de-
veloped in the male. The fifth ventral in the fem.ale is always
more or less rounded, and its surface is sometimes feebly im-
pressed. In the male the inner spur of the anterior and middle
tibife is dilated, sometimes very strongl}^ while in several species
I have been unable to notice any modification of the spurs, and
in the male of sexualis the inner spur is dilated on all the tibite.
In a few species, such as fuscus, the anterior tibise are slightly
thickened or bent in the male, but as these tibial modifications are
rare and slight I have not searched for them with special care.
The literature of this genus is confused in an inexplicable man-
ner. The typical form was described by Motschulsky, and the
genus limited by him to three species having uniform pubescence
without intermixed erect hairs, certain other species such as
yriseus and conformis, which, with the large material before me,
are not separable from Trichochrous, being at the same time made
the types of the genera Byturosomus and Emmenotarsus. When
Dr. LeConte published the first edition of the " Classification "
in 1861, he for some undiscoverable reason discarded all of Mot-
schulsky's names, and proposed " Pristoscelis " for the consoli-
dated genera of that author. This course was certainly unwar-
ranted, and however much it might be desired on personal or other
grounds to retain the name given by LeConte, I feel sure that
the adoption of it under the circumstances would be a violation
of the laws of priority, as well as some of the principles of ordi-
nary justice and equity. But even if we agree to adopt the name
Pristoscelis, the condition of the question is not materially im-
proved, because the original definition states that the prothorax
is " not serrate or ciliate at the sides," and this would exclude
all of Motschulsky's Trichochrous proper, as well as serricollis
and serridatus, which were subsequently added.
In describing Byturosomus from the type ^ris<??<s, Motschulsky
changed the name to rujjpes, which of course could not hold, as
Annals N. Y. Acad. Sct., VIII., July, 1895.— 33
468 Coleopterolofjical Notices, VL
griseus was certainly not a preoccupied name in Byturosomns or
Pristoscelis, altliough LeConte himself seems to have agreed to
the change even in the second edition of the " Classification." In
his revision of the Dasvtini (Proc. Acad., Phila,, ISGfi, p. 351) Le-
Conte assumes that Motschulsky did not know his griseus, but
had mistaken /».sci<s for it; but this idea seems to have been sub-
sequently abandoned, for (Class. 2 ed., p. 215) B^turosomus is
said to have been founded upon "Z). rufij)es Motsch. (griseus \\
Lee.)." Finally (1. c, p. 353) LeConte states that gi'iseus Lee.
and antennatus Motsch., are identical, and places the former as the
S3'nonym, although it antedates antennatus by some seven years.
It is not possible that more than a fraction of the species can
be defined in the following table, and it is only hoped that the
short characterizations ma}- prove of some avail as an index to
the descriptions. The species are rather monotonous, though ap-
parently not especially variable within the limits of the respective
sexes except in size; the sexual differences in outline are how-
ever sometimes pronounced, as before remarked : —

The only known specimen of this species is likewise a female,
and is from an unrecorded part of the State. The species is re-
markabl3- distinct in the prominent apical and acutel}' everted
basal angles of the prothorax, and in the ver}" short broad form
of the bod}-. The epiplenro? are not much wider than in the or-
dinary species of the genus, and are gradually narrowed behind,
but they are nevertheless somewhat intermediate between the
usual type and the broad horizontal form characterizing the
genus Eudas3'tes.

the upi)er surface with a scarcely perceptible metallic lustre; the legs and an-
tennae throughout dark rufous; pubescence somewhat long and fine, closely de-
cumbent, very sparse but cinereous and distinct. Head fully two-thirds as
mde as the prothorax, rather convex, polished, finely, sparsely punctate, the
anterior impressions large hut very feeble; epistoma at apex and labrum pale,
the latter In'oadly rounded; eyes moderately large and prominent; antennaj
a little longer than the prothorax, the fifth and seventh joints very feebly
dilated, the tenth transverse. Prothorax three-fifths wider than long, the sides
feebly convergent from ])ase to apex and feebly, evenly arcuate; basal angles
broadly rounded, the apical obtuse and nearly as broadly rounded as the basal;
apex truncate in the middle; base very broadly arcuato-truncate, slightly but
perceptibly wider than the apex, disk finely, remotely punctate, not at all
scabrous at the sides, the interspaces smooth and polished. Elytra two-thirds
longer than wide, only very slightly wider than the prothorax, feebly inflated
behind basal fourth, the sides becoming slightly arcuate; apex very broadly
rounded; humeri tumid but not large; punctures very coarse, impressed and
si^arse. Abdomen rather densely clothed with short fine pubescence, the legs
somewhat short. Length 3.2-3.4 mm. ; width 1.25-1.4 mm.
Colorado.
The type is a female having the fifth ventral prodnced at the
middle of the apex in an acute and prominent cusp, the surface
feebh' deflexed toward tip and very slightly impressed in the
middle, with some long erect black sette toward the sides ; the
genital segment is large, broadly arcuate at apex, broadly im-
pressed and finely, deeply canaliculate along the middle.
This species and the next, of the Rocky Mountain region, dif-
fer eonspieuousl}' in general t3'pe from the Californian species
which immediately precede. The side margins of the body bear
a close and even fringe of moderately short sette. In the present
species the elytral punctures become much finer and distinctly
closer toward apex, and the pubescence becomes correspondingly
a little less sparse. Two specimens.
12. T. ciliattis n. sp. — Subcylindrical, polished, black, the elytra rufo-
piceous, becoming darker toward Ijase; legs bright rufo-ferruginous through-
out; antennte pale testaceous, slighth' piceous at the extreme ai)ex; i)ubescence
rather long, moderately coarse, very .sparse, cinereous and distinct. Head
about two-thirds as wide as the prothorax, rather short, finely but strongly,
remotely punctate, polished throughout and not in the least .sciibrous; anterior
impressions very feeble, separated at apex bj- a large convex impunctate area;

transverse. Prothorax one-half ^-ider than long, widest at basal third, where
the sides are parallel and broadly rounded, thence becoming distinctly con-
vergent and very feebly arcuate to the apex ; basal angles very broadly, the
apical only a little less broadly, rounded; apex truncate and much narrower
than the base; punctures fine, but strong and remote, the surface perfectly
smooth, not at all rugose at the sides. Eh/Ira not (juite two-thirds longer than
wide, slightly wider than the prothorax, parallel and nearly straight at the
sides, the apex very broadly rounded; flanks longitudinally impressed toward

sparse toward apex. Abdomen very finely and feebly puuctulate and more
densely pubescent. Length 3.7 mm. ; width 1.4 mm.
Texas.
The single tj'pe of this species is also a female, having the fifth
ventral ver}- broad with the apex snbtruneate and produced in
the middle in a very broad and obtuse cuspiform projection,
w'liich is greath' obscured by the dense, stiff, blackish pubescence
at the apical margin, the surface feebl\- deflexed and distinctly
impressed in the middle toward tip, and with several long, erect,
black setje in a transverse series at each side. It is closely allied
to fipcu'sus, but is more elongate and cylindrical, with a some-
what less transverse prothorax dilferentl}' rounded at the sides, a
slighth' longer fringe at the sides of the elyti'a, and a shorter and
broader fifth ventral, with the apical cusp shorter and broader in
the female. In general form it is not unlike some species of
Scolytidse.

known at once by its narrow and subcylindrical form, color of
the legs and other characters as detailed above; it is an abun-

but the male does not ditler noticeably in form and has very
feeble abdominal characters.

California (San Francisco). I have scarcely any doubt that
this is the true antennatuH of Motschulsky, who states that it
resembles laticolliH Mann., but is smaller. It differs from lafi-
collis, however, in having long bristling pale hairs along the sides
of the bodj-, these being short and fimbriate in that species.
Some few of the hairs toward the sides of the elytra appear to be
semi-erect, and the species might therefore be almost as appro-
priately assigned to the fuscus group, some of the members of
which it resembles considerably. The two specimens before me
are females.

The single male before me is but slightly modified at the ab-

This species is evidently allied to the preceding, but differs re-
markabl}' in the sculpture of the elytra, these being also ver^^
much shorter. The single male in my cabinet has the fifth ventral

In both of these species the cilia along the sides margins of the

California (San Diego) — Cab. LeConte. I am quite uncertain
as to the position of this species, since the type is not before me
at present, and the published descriptions and short notes taken
by me some years ago are not sufficient. According to LeConte
the prothorax is gradually but strongly narrowed in front, with
the sides feebly arcuate and the hind angles obtusely rounded.
The elytra are coarsely punctured. The " last " ventral segment
of the male [fifth ?] is said to be longitudinall}' and broadly im-
pressed, which is very exceptional in this genus ; the sixth or
genital segment is however always sulcate.

Texas (El Paso). Mr. Dunn.
The male, if I have correctly identified this sex by the simple
but transversely truncate fifth ventral, appears to differ greatly
from the usual types of the genus in having both spurs of the
anterior and middle tibite simple and slender. The left antenna
of the t^-pe specimen is deformed, the third joint being very
elongate, enveloping the fourth externally and extending to the
base of the fifth. The four specimens before me are quite uni-

The single male serving as the t^'pe represents a species allied

arcuato-truncate. This species also resembles Listrns, and has
the tibial spines rather feebler than in incijnens, but the structural
characters place it in Trichochrous wathout doubt ; it is recog-

California (Calaveras Co.) Dr. F. E. Blaisdell.
A small but distinct species, the male described above having
the fifth ventral broadly and just visibh' sinuato-truncate at tip
but otherwise unmodified. It ma^' be known at once by its
sparse fulvous vestiture and coloration.
Two of the three specimens before me, represented by the
larger measurements, are blacker and duller, with the vestiture
more cinereous, but I have but little doubt that they belong to
the same species.

The description is drawn from the female, the male having the
head two-thirds as wide as the prothorax and the latter about one-
half wider than long but perceptibly narrower than the elytra ;
otherwise the two sexes are nearl}' alike. The fifth ventral of the
male is transversely truncate, and of the female rather strongly

California. Both of the specimens before me are females, the
fifth ventral being broadly and feebh' arcuate at apex and the
genital segment deeph' excavated in the middle. The second
specimen agrees with the first in its long mandibles and labrum,
but the gelatino-membranous epistoma is wide and distorted,
showing that but little reliance can be placed upon the form of
this part when it has this soft consistence. In these specimens
both the spurs of the anterior and middle tibiie are slender.

almost impunctate save a few piliferous punctures in the middle
toward base ; the genital segment is large, flat, truncate at apex,
the latter with a beveled coriaceous edge, the surface feebly di-
vided along the median line ; the fourth segment, and, to a less
degree the third, has a cluster of coarse punctures in the middle
toward apex, which bear short pointed spiniform and inclined
setJB which radiate in direction from the median line. This spe-

This species is very distinct in appearance because of its large
head, with the eyes small and distant from the prothorax. It is
evidently allied rather closely to propinquus, which is known at
present onl}- b}- the female, but dift'ers in the dense and conspicu-
ous pubescence of the pronotum and black abdomen. The sexual
characters of the male are very simple, the fifth ventral being-
truncate at apex, and the third and fourth segments completely
devoid of modified pubescence. Two males.

Arizona.
The male has the fifth ventral truncate at apex, the genital seg-
ment with a broad cuspiform apical emargination and broadly
impresso-canaliciilate along the middle. The description applies
to the unique male type. The left antennae of the type has the
fifth and sixth joints completel}' fused, with the division repre-
sented only by lateral notches ; antennal malformations appear to
be very common in this genus.
I have before me a single female, also from Arizona, having
similar coloration, except that the abdomen is entirely red, and
differing especially in its shorter and finer elytral pubescence and
very much more elongate epistoma ; it seems to represent a dis-
tinct species Avhich it is not advisable to describe at present, in
view of the peculiar sexual differences in the following species.

The male from which the description is drawn is much smaller
than the female, and has the fifth ventral evenly truncate at apex
but otherwise devoid of modification. In the female the head is
only slightly smaller when compared with the prothorax, but the
latter is decidedly smaller with regard to the elytra, and the dark
elytral stripes are much more evident in the single specimen rep-
resenting the latter sex. Two specimens.

This species is founded upon a single male, apparently from the
same source as the preceding female, but the differences are so
radical in the structure of the epistoma and basal angles of the
prothorax that it seems impossible to consider the two forms as
a single species. In this male the fifth ventral is verN' short, and
is broadl}' sinuato-truncate at apex.

This distinct species is represented before me by a single
female from an unknown part of the Territory. The longer hairs
of the elj'tra are so mnch inclined and so indistinct that their
presence might readily be overlooked, and the species assigned
to the preceding subdivision of the genus.

California.
The male type of this very isolated species has the fifth ventral
short and broadly, feeLly sinuato-truncate at apex, but without
further modification. Fimhriatus may be known at a glance by
the very short angulate and strongly- fimbriate prothorax, very
coarse and bristling pale setfe of the elytra, and by the fulvous
pubescence.
46. T. priiiiiosiis n. sp. — Elongate, subparallel, convex, jiolished, black,

toward apex, intermingled toward the sides of the pronotum with some long
.stiff black hairs; marginal cilia long, stiff", black and sparse throughout. Head
rather more than three-fourths as wide as the prothorax, convex, finely, sparsely
punctate, smooth and polished throughout, the frontal impressions small and
very feel )le; epistoma large, arcuato-truncate, strongly trans\erse, pale and cori-
aceous; labrum large, broadly rounded, blackish in color; eyes rather large
but not prominent, somewhat distant from the piothorax; antennje about as
long as the prothorax, not very stout, the outer joints moderately transverse,
.strongly asymmetric, with the apical sensitive patches well developed, fifth
scarcely dilated, third and fourth feebly picescent. Prothorax long, scarcely
more than one-fourth Avider than long, the sides just visibly convergent and
very slightly arcuate, more distinctly so near the base, the l)asal angles obtuse
but not rounded, slightly prominent though blunt; apical slightly obtuse and
nan-f)wly rounded; apex feebly arcuato-truncate, very little narrower than the
base, the latter evenly and strongly arcuate throughout; disk minutely, rather
sparsely punctate, smooth, not rugose at the sides. Elytra ut'ar\y three-fourths

hind, parallel, finely and rather closely punctate. Ahdomen clothed with
somewhat long coarse and cinereous pubescence. Length 15.1-4.2 mm.; width

California.
The two female types before me differ greatly in size, and have
the pubescence not only denuded in great part but more or less
broken, so that it is not possible to state its true development
with much precision. The species is remarkably distinct, as may
be judged by the description, and is one of those forms which it
is difficult to assigu to either Byturosomus or Emmenotarsus of
Motschulsk3^ proving that tiiose groups are not tenable as genera.

California (San Diego Co.). The above sketch refers to the
female, and the male, as remarked by LeConte, is quite different
in form, being less stout, with the head a little more than one-
half as wide as the prothorax, the latter scarcely more than one-
half Avider than long though similar otherwise, except that the
pubescence is a little darker and less obvious in the median parts
of the disk, and that the elytra are relatively shorter, narrowed
feebly from the base and not at all wider than the prothorax ; in
the female the elytra are much more than twice as long as the
prothorax, while in the male they are quite as conspicuously less
than twice as long. The fifth ventral in the male is broadly and
feebly sinuate at apex but otherwise unmodified, and, in both
sexes, the pronotum is feebly indented in the middle near the
base.

The female differs from tlie above described male in its larger
size, relativel}' longer and wider elA-tra, smaller head, more slender
a nd less claviform anterior tibia? and especiall}^ in its much

also in the smoother sculpture of the pronotum. The fifth ven-
tral of the male is very short and transversely truncate.
This species, which was taken in some abundance, is evidently
allied to brevicornis, but may be distinguished by the sparser
vestiture, less transverse prothorax wiiich is more evenly

The type of this species is also a, female. It resembles i)i-

the elytra, but ma^^ readil}' be distinguished hy the pale legs,
short prothorax with more obtuse apical angles, shorter and
broader epistoma and labrum, longer antennae and other char-

California (San Diego). An abundant species, represented in
my cabinet by a large series exhibiting as usual great variability
in size. The description here given is taken from the male, and
the female is broader with a relatively more transverse prothorax,
slightly smaller head and parallel elytra which are more broadly
rounded at apex. I cannot distinguish the original types of con-
formis from this species.

A very distinct form, represented before me by numerous speci-
mens displacing consideiable variation, the central dark area of
the pronotum being wholly obliterated in some cases. The male
above described differs from the female in its smaller size and
narrower form, and the female has the elytra larger and parallel,
the antennae relatively shorter and the head barelj^ three-fourths
as wide as the prothorax ; the fifth ventral of the male is feebly
sinuato-truncate at tip. Man}' of the examples before me have
the entire elytra rufo-ferruginous, except a clouded piceous area
at the base.

This species may be distinguished from the preceding by its
much more slender form, anteriorlj^ convergent sides of the pro-

This species is wholl}' different from any of those with which
it must be associated in this revision, especially in the elongate

Although to be phiced near hrevipilosus in a natural scheme of
classification, this species is not closely allied ; it is smaller, with
the pale setre of the elytra coarser and ver3' much more alnindant,

This species is the most remarkable of the genus in the devel-
opment of the male sexual characters at the abdominal vertex.
The male is described above, and the female diflers in having the
head and prothorax slightly smaller when compared with the
elj'tra, although not differing much in their own individual size
or form ; the elytra however are distinctly broader and relatively
shorter.
In the male the fifth ventral is deeply emarginate at the apex,
with the bottom of the eraargination rectilinear!}' transverse, but
the concave outline of the notch is continued on the disk past
this bottom truncature, forming a rounded depressed sinus with
the truncature as its anterior margin and its depressed floor hori-
zontal and flat ; the disk is broadly impressed, the impression
polished and impunctate toward the margins of the emargination
but elsewhere bristling with short erect black and spiculiform se-
tae. The inner spur of all the tibia? is strongly dilated.

The type of this species is a male, the fifth ventral being
simple and truncate at apex. It departs widel\' from any other
in the form of the prothorax, and may be recognized also by
peculiarities of vestiture, but in other respects is wholly similar
to the other species of the genus. A single specimen from an un-
recorded locality in the State.
CRADYTES u. gen.
There are several important points of difterence between this
genus and Trichochrous, the chief of which refer to thoracic
structnre, the rounded and obsolete apical angles and correspond-
ingly narrowed and advanced median parts of the apex, giving to
this somite a facies which is distinctively peculiar. The side mar-
gins of the prothorax ai'e strongly serrate, and the antennas are
relativel}' still shorter than in Trichochrous, broader and with the
joints more serrate or asymmetric, to a much greater degree in
ser^ricollis, however, than in the other species. The ungual ap-
pendages are less constant and equal in Cradytes than in Tricho-
chrous, and are united to the claws in only about basal half of
their length. In other structural characters, including the form and
extent of the epipleurifi, Cradytes is closely allied to Trichochrous.
The three species may be readily differentiated as follows : —
Body black, the elytra pale rufo-ferruginous 1. serricolliK
Bod J' black throughout; smaller species.
Erect seta? of the elytra pale 2. loii^icollis
Erect seta; black ; body very slightly stouter 3. sei'i'iilatus
In geograpliical distribution Cradytes is practically limited to
the arid regions of New Mexico and Arizona, but it probably ex-
tends southward into Mexico to some extent.

SYDATOPSIS 11. gen.
Aberrant antennal structure constitutes the chief differential
feature of this genus, nearly all the other characters being essen-
tiall}^ those of Trichochrous. The antennte in the male are dis-
tinctly longer than the head and prothorax combined, rather nar-
row and not incrassate, the joints strongly serriform, longer than
wide, strongly narrowed toward base and clothed sparsely with
long pale hairs, the eleventh narrower than the tenth, elongate
and pointed toward base and apex from the middle, the fifth very
slightly dilated. The ungual appendages are long and well de-
veloped.

The single male type in my cabinet has the fifth ventral broadly
truncate, the genital segment broadly sinuato-trnncate, flat and
finely canaliculate along the middle, and the inner spur of the two
anterior tibiae broadly dilated, thickened and as usual very obtuse
at apex.
SYDATES n. gen.
The single representative of this genus is a rather stout oblong
insect, which is intermediate in some of its characters between
Trichochrous and Listrus, but which differs from both in its long
and strongly serrate antennae and in the form of the nngual ap-
pendages, these being acutely pointed and leaving nearl3' one-half
of the inner claw free. The anterior tibine have a few long and
slender bristle-like spines along the outer side, which are much
less conspicuous than in Trichochrous, and the general habitus
and ornamentation of the body is remindful of Listrus. The
epipleurai are very narrow and indistinct, slightly wider toward
base and with their plane inclined upward externally.

reous but broadly blackish along the middle of the pronotum and in a broad
fascia at base and apical fourtli of the elytra, the fascijc narrowly interrupted
along the suture. Head two-thirds as wide as the prothorax, flat, finely and

Texas (El Paso). Mr. Dunn.
The male above described has the fifth ventral short and trans-
versely truncate, and the inner spur of the anterior and middle
tibife dilated. The female difters but slightly, having the head
distinctly and the ])rothorax slightly smaller, and the antennjB
more slender though only a little shorter ; the female seems also
to have the legs a little more slender and pale rufous throughout.

I.ISTRO:tIIIWl S u. gen.
The type of this genus is a species remarkabl}- distinct in habi-
tus because of its opaque sculpture, dense, even and closely ap-
pressed pubescence, feebly constricted prothorax with acute and
everted basal angles, and small prominent eyes situated at a con-
siderable distance from the base of the head, the neck being nar-
rowed posteriorlv. The antennae are rather long and slender,
though distinctly incrassate toward apex. The anterior tibiae
are cylindrical, with appressed pubescence and without trace of
external spines or setiv. The epipleurtv are narrow, vanishing
fixr before the apex but with their plane almost horizontal
throughout, and the ungual appendages are as long as the claws,
subequal and detached from the outer third or fourth of the clnw
as in Trichochrous. The remaining characters are those of the
tribe in general, the maxillary palpi being rather stouter than
usual and the tarsi long and iiliforni.
1. I>. sericatiis n. sp.— Elongate, suboval, strongly convex, black; legs
blackisli-piccous, the under side of the femora rufous, more broadly toward

blackish; head and pronotum opaque, densely and evenly rugose with small
irregular and anastomosing punctures, the elytra polished and finely but
closely punctured; pubescence whitish -cinereous, closely decumbent, even,
coarse, moderate in length and cxtiemely dense, without trace of erect hairs.

Nevada (Reno). Mr. Wiekham.
The t3'pe is a male, having tlie fifth ventral short and trans-
versely trnneate and the genital segment sinnato-truncate at tip
and broadly impressed at the middle of the disk. The tibia? have
a terminal fringe of short spinules internally and externally, bnt
I am unable to detect the usual two larger spurs.
I have before me a female, also from Nevada, which may be re-
ferred to this species for the time being, although the difterences
i\re extraoi'dinary. The sculpture of the head and pronotum is
much coarser and the pubescence of the eh'tra finer and twice as
sparse. The pronotum has a strong impressed line parallel to
€ach lateral edge and at some distance from it, not attaining base
or apex and of which there is no trace in the male, and the sub-
basal fovea of that sex is wanting.
ADASYTES u. gen.
Although not diftering much from certain forms of Tricho-
chrous in general habitus, the type of this genus is in realit}' more
closelj' allied to Listrus, the anterior tibiae being completel}' de-
void of short stout spinules; these are replaced by a few long
slender black and anteriorly inclined bristles. From Listrus,
however, it ditfers completely' in facies and in the even and non-
serrulate edges of the prothorax. The hypomera have a large
rounded and deep imi^ression near the inner edge anteriorly,
equally developed on each side in the type and prol)ably a normal

California (San Diego). Mr. Dunn.
The unique uiale type has the fifth ventral truncate at apex and
somewhat impressed on the disk from side to side in a posteriorly
arcuate area; the inner spur of the anterior and middle tibijt is
dilated, with the tip obtuse but acutely pointed at the middle of

LISTRrS :Motsch.
The genus Listrus, as here considered, is an extensive and very
homogeneous aggregate, characterized by an elongate and sub-
parallel convex body, generally sparse and variegated vestiture
without intermixed set;^, slender tarsi in both sexes, with the
basal joint of the posterior slightly longer than the second, the
fifth somewhat dilated toward tip and canaliculate above at apex
as usual throughout the family, the anterior tibi;e slender, cylin-
drical, usually with closely decumbent ashy pubescence and only
Coleopterological Notices, VI. 541
occasionally with two or three very slender distant external
spines, these being completely obsolete as a rnle.
Antennae short, feebly incrassate, only slightly thongh dis-
tinctly serrate, with the first joint always much dilated and darker
in color, the fifth larger than the fourth or sixth, and the eleventh
evenly elongate-ovoidal and obtusely acuminate. The prothorax
is dilated toward base, with the lateral edges minutely serrulate
and having a close-set even fringe of short posteriori}' and supe-
riorly recurved setae, which are almost invariably pale ash}' white
in color, the apical angles alwaj's very obtuse. Epipleurai very
narrow but dilated toward base, with their plane strongly in-
clined upward throughout. The ungual appendages are thick,
equal and fully as long as the claws, the apical third or fourth of
which is free.
The author of the genus did not seem to have a very clear con-
ception of its real scope, as the first species which he assigned to
it — constricticollis (=zconstrictus Lee.) — is generically quite dis-
tinct from the species of LeConte and Mannerheim, which he
subsequently states should be included, and which alone agree
with his generic diagnosis in having the sides of the prothorax
serrulate. The other tvvo species described by Motschulsky have
not been identified and are probably also generically different
from rotundicollis, canescens, etc. I agree with LeConte, how-
ever, that it is probably the best course to regard Listrus as con-
stituted below, and not as the equivalent of Eschatocrepis Lee.
Our species are numerous, and those before me may be quite
readily distinguished among themselves as follows : —

lato-rugulose.

The subjoined remarks add little or nothing to the descriptions
and need not be repeated. No species of Listrus having the pu-
544 Coleopterological Notices, VI.
bescence evenly distributed, as indicated by these descriptions, is
known to me from the true Pacific coast faunal province.
The statement in the table of LeConte (Proc. Acad., 18G6, p.
357), that the prothorax in canescens, difficilis and rotundicollis
is not wider than long is very much in error, and is another ex-
ample of a singular personal equation previously alluded to (Col.
Not. Ill, p. 205), by which the author quoted continually over-
-estimates the length of this part of the bod.y in terms of its width;
at the same time, it should be said that this overestimation is more
or less general among systematic writers, and results largely from
a natural cerebral bias which it is difficult to explain satisfac-
torih' ; it is only mentioned in the present connection because of
its excessive amount.

This species and the preceding are distinguished from all
others of the genus b}- the peculiar sculpture of the pronotum,

convex elytra, longer pubescence, color of the antennae and pecu-
liarities of thoracic structure previously stated. It is represented
b}' a single female specimen.

and with the tips of the elytra less acute. The fifth ventral of
the male is broadly but strongl}^ sinuato-truncate at apex, flat-

California (San Francisco). Mr. Dunn.
The single t3'pe is a female, having the fifth ventral rather long
with the surface feebly reflexed at apex, the latter bristling with
dense pubescence. The two basal joints of the hind tarsi are
subequal in length, but in another female, which I took at San
Francisco, the basal joint is distinctly longer than the second,
and, as the prothorax is much less transverse, it probabl}- repre-
sents a closely allied but distinct species.
This species is distinguishable at once from motschulskiij with
which alone it can be confounded, b}^ its much shorter pubescence,
sparser and coarser punctures of the pronotuni and other
characters,

The single female type represents a species which cannot
readily be confounded with any other known to me, being allied
to densicollis only in the very close punctuation of the prono-
tum, but dilfering remarkably in its relatively larger head and
ver3' much more slender antennce ; the sides of the prothorax are
less convergent anteriorly than in densicollis, as might be infer-
red from the large head.

California (Xapa and Sonoma Cos.).
The punctures of the head and pronotum are much more shal-
low than usual. A specimen before me, assumed to be the male
of the above-described female, has the head relative!}' only
slightl}' larger and the eyes only a little more pi'ominent, the
fifth ventral much shorter, with its tip truncate, feebly deflexed
and with a broadl\' obtuse median cusp, the surface with a small
deep rounded fovea at the middle but without erect hairs, the
genital segment not visible, but with the under surface of the
dorsal pygidium largeh^ exposed behind.
The male modification of the fifth segment is similar to that
indicated by LeConte for his difficilis (Proc. Acad., 1866, p.
358), but several species were included by the author under that
name, and the male of the true difficilis has no such medial
fovea, as can be proved b}' a large series taken by the writer in
the vicinity of San Jose.
10. L.. iiiacillOKUJii n. sp. — Elongate, parallel, narrow and convex, pol-

Avide as the prothorax, the eyes prominent, distant from the base by nearly one-
half of their length; punctures tine but deep, rather sparse, the frontal im-
pressions wide and moderate; antennte long, almost equalling the head and
prothorax, lilack, with the second joint scarcely paler, the tenth perceptibly
longer than wide, eleventh oval. Prothorax scarcely one-half wider than long,
Avidest and evenly rounded at basal third, the sides thence rather strongly con-
vergent and nearly straight to the apex, the latter arcuato-truncate and not
quite as Avide as the head ; disk finely but deeply, not very densely perforato-
punctate, rugose in much less than lateral fourth; interspaces sparsely and
feebly variolate or indented. Scutellum moderate in size, albido-pubescent.
Elijtra twice as long as Avide, not evidently Avider than the prothorax, parallel,
rather obtusely parai)olic in about apical fourth ; humeri rounded, scarcely at
all tumid; punctures moderate in size, rather feeble and close-set. Legs black,
moderately long and slender. Length 3.25 mm. ; Avidth 1.1 mm.

The unique example is a, male and has the fifth ventral fiat,
completely unmodified, with the usual sparse decumbent pubes-
cence, and with the apex broadly truncate. The antennae are un-
usually long, and this is probably a specific character, as I have
not been able to note much variability- in this organ due to sex.
11. L. pardali!^ n. sp. — Oblong-oval, convex, polished, l)lack witli a

on the elytra, of which a narrow une\'en fascia at apical third is particularly
noticeable. Head fully two-thirds as wide as the prothorax, the eyes rather
large but not very prominent ; punctures somewhat fine and well separated,
the interspaces flat and smooth toward the middle; frontal impressions broad
but distinct; antennae about one-fourth longer than the prothorax, somewhat

transverse, one-half wider than long, the sides feebly convergent and straight
in apical half to the broadly rounded angles, becoming parallel and feebly
arcuate posteriorly ; apex Ijroadly arcuato-truncate, much wider than the jjeduu-
culiform part of the base, which is pronounced ; disk strongly and closely per-
forato-pttuctate, the interspaces flat and smooth to^^•ard the middle, scabrous
and opaque in distinctly less than lateral fourth. Etijtra nearly twice as long
as wide, scarcely wider than the prothorax toward base but feel)ly inflated in
apical half, very obtusely and subcircularly rounded liehind ; punctures moder-
ately large and somewhat sparse. Legs moderate, the hind tarsi long and
slender, almost as long as the tibiae. Length 3.25 mm. ; width 1.25 mm.
California (Mountains of Sta. Cruz Co.).
The single type is a female. In this species the pattern of
cinereous hairs on the elytra is better defined and with the pubes-
cence apparently' more persistent than in those which precede,
and it is further remarkable in having the fringe at the sides of
the prothorax composed of hairs which are longer, stifter and
darker than usual, and in the posterior inflation of the elytra.

throughout, except the two usual long black and erect ambula-

l)roadly, feebl}^ bisinuate at apex, flat, with a fine median canali-
culation. The dorsal p3'gidium projects behind as seen from be-
low, its under surface being clothed with blacker and more erect
hairs, and it is probably this which was observed by LeConte (1.

California (Sta. Clara and Napa Cos.). The female is de-
cidedly stouter than the male above outlined, with the head
smaller and the elytra shorter and broader; the fifth ventral of the
male is short though distinctly longer than the fourth, and is
transverseh' truncate at apex, the surface even and unmodified ;
the genital segment is broadly' sinuate at apex, with a narrow
median canaliculation,and the dorsal pygidium is visible at apex.
In the female the fifth ventral is longer, rounded, with the surface
deflexed at apex and apparently somewhat impressed. This
species is represented in my cabinet by a large series.
I have before me three specimens from Truckee, in the Sierras,
which are almost undistinguishable from the typical forms of
difficilis, but which have the fifth ventral of the male broadlv
and feebly sinuate at apex ; they apparently' represent a closely
allied species or subspecies.

evenl}^ truncate at apex, about one-third longer than the fourth,
with its surface completely unmodified and clothed with the usual
decumbent ashy pubescence.
This species is allied to difficilis, agreeing in the general char-
acter of the sexual modifications, but diflfers much in its longer
elytra, longer coarser denser and more confusedly denuded pu-
bescence, less transverse prothorax and other features.
"20. L.. tritlis □. sp. — Narrow, elongate and convex, the integuments
black, shining and slightly brassy bnt densely clothed with rather long coarse

transversely in the position of the usual fascia at apical fourth are particularly
evident, ffend fully three-fourths as wide as the prothorax, the ueck rather
strongly narrowed ; eyes moderate in size but decidedly prominent ; punc-
tures moderately sparse, the interspaces coarsely rugose but polished ; subapi-
cal impressions feeble ; antennae slender, nearly one-half longer than the pro-

in basal half, thence strongly convergent and straight to the obtusely rounded
apical angles, the serrulation very fine and feeble ; apex feebly arcuate ; disk
opaque under low power ; punctures moderately close, the interspaces strongly

California ( Lake Co.).
The three males before me represent a close ally o^difficilis, but
can be specifically distinguished by the more elongate body
clothed with longer, denser and much coarser pubescence, the
latter being denuded in definite areas only behind the middle.
From fi.delis it also differs in this last character, and in its
smaller eyes and more opaque and rugose sculpture of the pro-
notum. The fifth ventral is about one-half longer than the
fourth, truncate at apex and unmodified on the disk.

California (San Francisco). Mr. Dunn.
A single pair of this species was sent to me some 3'ears ago,
and the description is di'awn from the male, the female being al-
most similar but slightly stouter, with a distincth' smaller head
and less prominent eyes. The sexual characters are of the same
type as in difficilis, from which it can be known at once by the
confused pubescence and shallow opaque sculpture of the prono-
tum. A single female from southern California represents a spe-
cies closely allied to this, which it would serve no good purpose
to define at present.

California (Mendocino and Napa Cos.).
The three specimens in my cabinet are females, the fifth ven-
tral being ronnded behind and feebly deflexed, the apex of the ab-
domen bristling with a few very long and erect black setfe. Va-
riegatus resembles luteipes almost perfectly, but is larger, with a
relatively narrower and less transverse prothorax, shorter vesti-

This species is allied to variegatus, and differs in its shorter
and more opaque pronotum. The general characters of the de-
scription are taken from the male, in which sex the fifth ventral
is trapezoidal, broadly truncate at apex and unmodified on the
disk ; in the female the head is relatively slightly smaller, but
the eyes are almost as prominent as in the male. Five specimens.

The type from the Sierras seems to be a female, and the Pi'ovo

isolated species of the genus, and may be readily known by the
evenly banded arrangement of the vestiture.

The two males, which are the sole representatives of this dis-
tinct and diminutive species, have the fifth ventral truncate at
apex, the disk feebly flattened posteriorly^ the white hairs there
becoming slightly more erect and directed obliquely tow-ard the

The single male before me is the type of an interesting and iso-

are of the usual structure. The fifth ventral of the male is trun-
cate at apex but otherwise unmodified. Famelicus is the
smallest species of the genus discovered thus far.

Nevada (Reno).
The description relates to the female, and the male is, as usual,
smaller and narrower, parallel, not inflated behind, with a larger
head and more prominent eyes, and the prothorax only about two-
fifths wider than long ; in addition, the basal denuded band of the
female elytra is less evident. The fifth ventral of the male is
broadly sinuato-truneate at apex but otherwise unmodified.
I took a good series of this species, which is not unusually vari-
able, although the tibia? and tarsi of some specimens become pale
and reddish.
DASVTELLITS n. gen.
The species of this genus are the smallest members of the tribe
Dasytini thus far discovered in North America. The}' are allied
to I)asytes,as here accepted, in general organization, especiall}' in
having an impressed submarginal pronotal line delimiting a lateral
area of greater rugosity, and in the ver}- narrow ei)ipleur;'e which
gradually- become subvertical and evanescent behind, but difier
in having the ungual appendages well developed and generall}^
fully as long as the claws. The anterior tibia? are slender,
clothed rather densely with short and decumbent ashy hairs, and
are completely devoid of spinules. The antenna? as a rule are
much shorter and more incrassate toward tip than in Dasytes,
and the marginal cilia of the body are A'er}- short and lie close to
the surface, being usually altogether invisible under low power.

feebly impressed in the middle near the tip. The epipleun^ are
very narrow, subvertical, and become wholly obsolete long before
the apex, as usual in this and allied genera.

with a scarcely visible blnish lustre; legs pale; antennae pale testaceous,
blackish toward apex; pubescence rather fine, sparse, decumbent, cinereous,
distinct but not conspicuous and without ti'ace of erect hairs or bristling fimbria\
Mead fully four-fifths as wide as the prothorax, flat, feebly reticulate, the
punctures not distinct; frontal impressions small, feeble and Avidely separated;
epistoma rather long, pale; lalirum pale, long, strongly rounded ; eyes mod-
erately large, convex and prominent; antennte much longer than the protho-

the sides just visibly convergent, evenly and moderately arcuate from base to
apex, the angles all obtuse and somewhat rounded though evident; apex feebly
arcuato-truncate, very slightly narrower than the base which is only a little
more arcuate; disk obsoletely reticulate, finely and sparsely punctate, rugose
at the sides, the sublateral impressed line distinct. Elytra two-thirds longer
than wide, two-fifths wider than the prothorax, parallel, the sides feebly arcu-

Arizona. Mr. Wickham.
M}' single representative of this species is a female, the fifth
ventral being evenly but broadly rounded behind and apparently
\Qvy slightl}' impressed on the disk at apex ; the genital segment
is smooth, broadly and evenly arcuate at apex, with the disk
transversely impressed and not in the least canaliculate along the
middle. The ungual appendages are well developed and fully as
long as the claws, to which they are attached nearly throughout.
This and the preceding are the smallest dasytide forms known
to me.

The description is drawn from the female, that sex liaving the
fifth ventral much longer than the fourth, triangular, with the

Southern California. Mr. H. C. Fall.
This species is evidently rather closely related to the last, l3ut
it differs in vestiture, in its more posteriorly broadened form, in
its longer epistoma, and in the less narrowl}' truncate subtrian-
gnlar fifth ventral of the female. The description is drawn from
that sex for facility of comparison, but the male differs scarcely
at all, having the elytra A^ery slightly shorter and the apex of the
fifth ventral broadly arcuato-triincate. In both of these species the
ungual appendage is full}- developed and as long as the claws.

Kansas, Nebraska and Texas (Austin). The female described

above has the fifth ventral evenl}^ and strongly arcuate at apex.
The single specimen from Austin, which I regard as the male,
has the elytra relativel}' shorter and broader, with the fifth ven-
tral somewhat narrowly truncate at tip.
It is singular that Dr. IjeConte should have failed to observe
the strong aflfinity of this species with those which he placed in
Dasytes ; there is absolutely no single point of resemblance with
Dolichosoma foveicoUis, with which it was associated by that
author.
6. D. degeiier n. sp. — Elongate, siiboval, convex, polished, black, the
elytra more or less paler and piceous; femora pieeons-black, the trochanters,

paler toward tip; pubescence coarse, cinereous, decumbent and distinct but
sparse. Head three-fourths as w'ide as the prothorax, transverse, feebly con-
vex, strongly reticulate and obsoletely punctulate, the frontal impressions
feeble and widely separated; epistoma short, the labrum small, transverse and
strongly rounded, the mandibles and labrum somewhat pale in color; eyes
small but rather prominent; antennse short and slender, distinctly longer
tlian the prothorax, the outer joints wider, the penultimate transverse. Fro-

oiit. Length 1.5 mm.; width 0.75 mm.
Arizona (Benson). Mr. Dunn.
The t3^pe above described seems to be a female, the male hav-
ing the sides of the prothorax broadh^ arcuate throughout and
nearly parallel, with the fifth ventral broadly and feebly arcuato-
truncate at tip. There is some variability displayed in the six
specimens before me, the upper surface l)eing deep black through-
out in some, and, in one example, the prothorax becomes twice as
wide as long and almost fully as wide as the elytra ; but I believe
that this specimen ma}- possibly represent a closel}' allied though
distinct specific form. The specimens are all in rather poor
condition.

Arizona (near the Canon of the Colorado).
The female is described above and this sex has the sides of the
fifth ventral convergent, the apex being narrowly arcuato-trun-
cate. The male is larger than the female and has the prothorax
less transverse, with the sides arcuate and only slightly conver-
gent, the apex of the fifth ventral onl}- a little more broadly trun-

Goleopterological Notices, VI. 5^1
The sex of the type is not clearly determinable, but the two
specimens from Arizona are mutually similar and are more prob-
abl}' male than female. The single example from Texas seems to
belong to the species, although the elytra are relatively larger
and more elongate, and the size distinctly larger ; it is not in-
cluded in the measures.
DASYTES Fabr.
This name, as applied to the American representatives, will in-
clude those species of the tribe Das^'tini which have the anterior
tibiifi slender and devoid of spinules,the ungual appendages equal
but very short or rudimentary, and the pronotum with a roughly
sculptured and abruptly limited marginal area. The epipleurse
are even less developed than in Trichochrous, being moderately
"wide with their plane inclined upward at base, rapidl}' assuming
the form of a mere fine line very near the elytral margin on the
vertical flanks and disappearing completeh* far in front of the
apex. The head is much shorter, the eyes smaller and the an-
tennre longer and more filiform than in that genus, and the frontal
impressions are generally' feeble or obsolete. The erect hairs in-
terspersed among the ordinary pubescence are present in some
species and altogether absent in others, proving still further that
this character is not of generic value in Trichochrous.
The species are somewhat numerous and those known to me
may be outlined as follows : —
Submarginal line of the pronotum strong, Impressed and entire; body gener-
ally more cuneiform 2
Submarginal line feeble, frequently only evident as an abrupt division be-
tween the smooth and rugose portions of the surface.
Elytra without longitudinal vittse 3
Elytra each -with several dark vittiform lines 4
2 — Pubescence distinctly intermingled with longer erect black hairs.
Elytral vestitiire blackish throughout; thoracic sculi)ture rather dense.

tion is drawn from a male taken in the alpine regions of Colorado,

The allusion to cinereous hairs in the description of LeConte is
erroneous as far as the el^^tra are concerned.
The ungual appendages are thick and subglobular, unusually
developed for this genus, but seem to be attached in rather less
than basal half of the claws.

California. The single specimen, which I took in the coast
region north of San Francisco, is a female, and the fifth ventral
is broadly rounded and feebly impressed in the middle at the
apical margin; the genital segment is large, slightly deflexed,
broadly angulate at apex and is feebly impressed at the middle
of the disk. There can be scarcely any doubt at all that this is
the species of Motschulsky, as it agrees with his description in
every essential feature ; the species identified by LeConte under
the name hreviusculus, is however quite a different thing, Avhich
I am unable to place in the absence of the t^-pe, but which ma}-
possibly be the nifens described above.

The female described above has the fifth ventral rounded be-
hind, the apex subtruncate in the middle, the genital segment
being perfectly flat and even and strongly-, evenly rounded at the
apex. In general form and vestiture this species more nearly
resembles macer, of the next group, than any member of the
breviu senilis section of the genus, but difiers in its coarser and
sparser elytral punctures and bicolored legs.
7. D. fastidiosilS n. sp. — Elongate and subparallel, rather depressed,
shining, l)lack with a feeble seneous lustre; legs blackish, the anterior and
Intermediate tibi* slightly rnfescent especially toward base; antenna) black;
piibescence rather long, suberect, cinereous, moderately dense, intermingled
■with stiff sparse erect black setce anteriorly, which become pale, abundant and
scarcely distinguishable from the ordinary pubescence on the elytra. Head
about two-thirds as wide as the prothorax, transverse, polished, the punctures
strong, rather close and slightly unequal in size; frontal impressions very
feeble; epistonia rather long, the labrum broadly rounded; eyes prominent;
antennse subfiliform, not quite as long as the prothorax, the penultimate
joints slightly wider than long. Prothorax fully two-thirds wider than long,
the sides rounded, a little more convergent anteriorly, feebly serrulate; basal
angles obtuse but not rounded, minutely prominent and sliglitly reflexed;
disk polished, finely Ijut strongly, rather closely punctured, broadly rugose
near the sides. Elytra a little more than one-half longer than wide, one-third
wider than the prothorax, the sides feebly arcuate and just visibly dilated
behind; apex broadly and evenly rounded; disk finely but strongly and
rather densely punctured. Abdomen minutely and closely punctulate, sparsely

This species is distinct in having the scattered erect setffi quite
well developed anteriorly but subobsolete on the elytra; it is de-
scribed from a female from an unrecorded part of the State, and
is apparently' unique.

California. The example above described has the fifth ventral
broadl}' truncate at apex. The legs in this specimen are pale, but
in the types of LeConte they are said to be '' nigro-piceis." The

The t3'pe has the fifth ventral segment short, broadh^ trapezoidal
and rather broadly truncate at tip. The tibitB and tarsi appear
to be very slightly picescent occasionally. This is a very remark-
able species in the nature and disposition of the vestiture, but
seems to be wholly congeneric in structural characters. Three
specimens.
DASYTASTES n. gen.
I have applied this name to certain small species resembling
Dasytes quite closely in general organization, but differing invari-
ably and radically in having the entire disk of the pronotum sim-
ply punctate and devoid of all trace of the abruptl}' defined mar-
ginal rugose area, which constitutes so constant and characteristic
a feature in Dasytes as limited above. In addition to this it may
be stated that the antenni>^ are shorter as a rule than in Dasytes,
and are more definitely incrassate toward apex.
The six species known to me may be thus defined in brief: —
Body uniformly black or piceous-black in color.
Elytra! vestiture cinereous throughout.
The pubescence short.
Head small; sides of the prothorax broadly subexplanate; legs feebly
bicolored 1. cataliiiae
Head large; sides of the pronotum evenl}^ convex and declivous; legs
pale rufo-ferruginous throughout 2. reilliSSUS
The pul)escence long, fulvo-cinereous; legs bicolored 8. otiosus
Elytral vestiture dark and inconspicuous, becoming paler and coarser to-
ward base and at the apex 4. dispar
Bwly bicolored, the head and prothorax pale and rufous.

Head pale throughout; elytral vestiture short, even, dense and pale cinere-
ous over the entire surface 5. rilficollis
Head blackish toward base; elytral vestiture longer, sparse and dark in
color, becoming cinereous near the apex and toward the humeri.

California (north of San Francisco).
Of this interesting form I have before me three specimens from
as many distinct localities; of these only one satisfies the above
description, this example having the fifth ventral broadly trun-
cate and being without doubt the male. The other two speci-
mens have darker legs, the femora in one being blackish, and a
broadly and evenly rounded elytral apex ; the head in one of these
two specimens is smaller than in the other and both have the
fifth ventral more or less evenly and broadly truncate at tip. It
is probable that there is some specific difference which cannot be
advantageously defined at present.

California,
The type and only specimen known to me has the fifth ventral
rather short, trapezoidal and truncate, and the genital segment
strongly and evenly rounded behind, with the disk perfectly even.
I am, however, not certain of the sex of this individual, for the
fifth ventral seems to be truncate in both male and female in this
section of the genus.
4. D. dispar n. sp. — Somewhat short, strongly convex and subo\al,

ESCHATOCREPIS Lee.
In this genus the ungual appendages are equal, rather slender,
well developed and as long as the claws, but are clearly detached
from them except near the base ; in other respects Eschatocrepis
is allied to Listromimus, but differs in the form of the epipleurae,
which are nari'ow and horizontal, with the plane gradually turned
upward and inward posteriori}'. The anterior tibije are C3'lin-
drical and devoid of all trace of spinules along the external side,
and the eyes are large and basal, the antenna? rather short and
either gradually incrassate or with an abrupt three-jointed club;
they are scarcely at all serrate. The pronotum has a deep im-
pressed submarginal line in both sexes.

Coast regions of California from Humboldt to San Diego.
This abundant species seems to be resolvable into two or three
closely allied forms, but it would scarcely be worth while to un-
dertake the definition of them without very full series from care-
fully recorded localities. One form from San Diego is certainly
distinct in its much more feeble thoracic constriction, denser
pubescence and acute elytral apices ; another from Sta. Barbara
is more elongate in the body and more densely pubescent than
the typical forms, in which the el^'tral pubescence is relativel}'
sparse, dark and inconspicuous.
In the male the fifth ventral has a transverse and rectangular
apical emargination, with the adjacent surface slightly declivous,
and I can perceive little or no variation in this sexual character
in the various allied forms alluded to above.
ALtOIVYX Lee.
The parallel form of the body and structure of the epipleurte
will readil}- distinguish the representatives of this genus from the
allied forms with similar asymmetric ungual appendages. The
epipleura' are wide, flat and subhorizontal throughout, preserving
their width almost unaltered to within a short distance of the
apex and there terminating somewhat abruptly ; their surface is
finely punctured and pubescent, and the side margins of the elytra
are correspondingly reflexed. The antenna? are rather short,
feebly incrassate and are scarcely at all serrate, the eyes large and
basal, the anterior tibiae devoid of spinules, the maxillar}^ palpi
somewhat stout and pale in color, and the vestiture very feebl}^
developed. The prothorax is not at all constricted near the apex,
and the pronotum has at each side a strong excavated line parallel
to and at some distance from the lateral edge, the intermediate
surface being broadly subexplanate but only a little more strongly
sculptured than the median parts of the disk.

The materiul in my cabinet seems to indicate the three follow-
ing species : —
Submarginal line of the pronotura entire, extending to the apex.
Sides of the j)rotliorax sinuate near the basal angles, which are right and
somewhat prominent 1. scillptilis
Sides almost evenly and feel)ly arcuate, not more than straight near the
basal angles, which are obtuse and not at all prominent. . .2. deiiudatus
Submarginal line abruptly abbreviated at apical fourth or fifth of the length;
basal lobe of the prothorax more gradually formed and less pronounced.
3. disjunctus
Allonyx seems to be limited in its range to the coast regions of
middle California from Sta. Barbara to Mendocino, being perhaps
still more circumscribed than Eschatocrepis. Many California
trees are well known to be similarly limited in range, such as
Sequoia and Piniis insignis.

California (north of San Francisco).
The three examples before me are males, the apex of the fifth
ventral being transverse and abruptly and deeply sinuate at the
middle, the genital segment being deeply bilobed. In the female
the legs are doubtless paler. This species difters from sculptilis
in having the sides of the prothorax very feebh' and almost evenly

the apical angles are occasionally feebly prominent anteriorlv.

California,.
The type of this species is a female, differing from the female of
sculptilis in having the submarginal impressed line of the pronotum
abruptly ending at about apical fifth of the length. The fifth ven-
tral is truncate as in sculptilis.
VECTURA n. gen.
In this genus the body is cuneiform, with the head small and
more elongate than usual, the antennae being moderate in length,
scarcely serrate and feebly incrassate at apex, the eyes situated
before the base of the head and slightly elongate, and the pro-
thorax more or less constricted near the apex, with the basal an-
gles acute and prominent. It resembles Allonyx to some extent
in the form of the epipleuri^, these being rather wide, flat, subhor-
izontal and pubescent, but, unlike those of Allonyx, becoming
gradually narrow behind the middle. The inner claw has a very
long and rather thick corneous expansion and the membranous
appendage is correspondingly shortened but extends to the tip of
the claw. The tibia* are devoid of spinules as usual in this group.
The two species known to me may be distinguished as follows : —
Pubescence not entirely concealing the integuments; ])rothorax strongly con-
stricted behind the apiciil angles, which are very acute and prominent later-
ally 1. loiigiceps
592 Coleoi^terolofjical Notices, VI.
Pubescence extremely dense, completely concealing the integuments; protho-
rax very broadly and oljsoletely constricted near the apex, the angles later-
ally obtuse, rounded and scarcely at all prominent 2. allucans
In geographical range Vectura is i)robably limited to the great
arid and elevated internal basin region, between the Sierra Nevada
and Rocky mountains.

moderately convex, feebly shining, pale ochreo-testaceous throughout, the
metasternum, maxillary palpi and antenna; toward tip blackish ; pubescence

without trace of erect hairs; marginal fringe composed of short dense and pos-
teriorly inclined white hairs. Head small, elongate, three-fifths as wide as
the prothorax, flat, Avith indistinct sparse punctules, the impressions very
feeble; epistoma transverse but well developed, the labrum large, broadly
arcuate at tip ; eyes elongate-elliptical, feebly convex and not attaining the
base; antennae but feebly serrate, one-fourth longer than the prothorax, the
fifth and seventh joints much larger than the sixth or eighth, last three joints
larger, the penultimate slightly transverse. Frothorax one-fourth wider than
long, the sides feebly convergent from the base, feebly arcuate, slightly and
broadly sinuate near the base, deeply constricted behind the apical angles
which are laterally acute and very in'ominent; basal angles slightly acute,
everted and prominent; apex arcuate, narrower than the base, which is broadly
and arcuately lobed; lateral edges finely serrulate; disk finely, feebly and
rather closely but indistinctly punctate, the submarginal excavated line ex-
tending only to apical fourth. Elytra three-fifths longer than wide, oval,
gradually w ider to apical two-fifths, where they are more than twice as wide
as the prothorax; sides evenly and feebly arcuate; apex acutely ogival, the
sutural angles minutely acute and posteriorly prominent; lateral edges nar-
rowly reflexed; humeri exposed and transversely rounded; disk finely )mt
strongly, distinctly and closely punctured, the interspaces shining. Under
surface densely clothed with appressed white pubescence, the legs very slender
and moderately long. Length 3.6 mm. ; width 1.55 mm.
Arizona (Yuma). Mr. Dunn.
The typical specimen described above is a female, having the
fifth ventral rounded behind, with the disk feebly impressed in
the middle at the apex. I have before me two females not mutu-
ally differing at all in structure.
2. V. albicans n. sp. — Stout, moderately dilated posteriorly, strongly con-
vex, the surface completely concealed by a dense even coat of rather long and

broadly and arcuately lobed; disk convex, completely concealed by the vesti-
ture except the excavated submarginal line, which does not attain the apex or
base. Elytra large, two-thirds longer than wide, gradually wider posteriorly,
and, at apical third, twice as wide as the prothorax ; apex acutely ogival, the
sutural angles slightly obtuse; humeri exposed at base; lateral edges nar-
rowly reflexed. Under surface clothed with an extremely dense crust of
white decumbent pubescence, the legs rather short but slender. Length 3.25
mm.; width 1.5 mm.
Utah (southwestern). Mr. Weidt.
Both of the specimens before me seem to be females, the fifth
ventral segment being strongly rounded at apex. This species
differs from the preceding in its denser coating of pubescence,
shorter but broader head and other characters.
PSEUD ALLONYX n. gen.
This genus resembles Allonj^x in the structure of the tarsal
claws and nngual appendages, but the inner claw is distinctly
smaller than the outer and more abruptl}- bent at apex, and its
appendage is larger and thicker and closely adherent to the claw
almost throughout its length ; the appendage of the outer claw is
small and altogether basal. It difters greatly from Allonj^x in
the form of the body, and in having the wide flat punctate and
horizontal epipleurje gradually inflexed upward in plane toward
apex. In the structure of the eyes, antennjB and tibi» it agrees
in general with Allonyx. I know of but one species at present.

female, and the fifth ventral is broadly rounded behind. The
male is undoubtedly narrower and less dilated behind. The apex
of the elytra and the lateral edges to a slight degree posteriorly
are rufous or rufescent.
LEPTOVECTIRA n. gen.
Although evidentl}- belonging to the well defined Allonyx
group of the tribe by reason of thoracic and ungual structure, the
single type of this genus ditfers greatly in general appearance
from any of the others in its Listrus-like body, with the elytral
epipleuraj narrow and gradually disappearing posteriorly in a fine
line on the external tlank very near the edge as in Das^'tes. The
inner claw has a ver^' large lamelliform appendage, which is ap-
parently closely affixed throughout its length, the outer being
simply obtusely swollen or subdentate internall}' at base.

The fifth ventral segment in the single type before me is
strongly rounded at apex. This striking species can be at once
identified by its elongate elytra, variegated vestiture and thoracic
structure.
MECOMYCTER Horn.
In this genus the ungual appendages become completel}^ obso-
lete, the claws being at the same time unusually slender and with
a small internal enlargement at base. The epipleurre are subhori-
zontal and moderate in width, becoming extinct behind the mid-
dle, and the genus further difiers from the members of the Allonyx
group, which it resembles to some extent, in having all the tibiae
beset externally with a few blackish spinules,aud in the complete

gate head is not strictly peculiar to Mecomycter, as it exists to a
pronounced degree also in Vectura. The two species can be
separated thus : —
Prothorax elongate, -witliout a lateral projection behind the middle.

The single specimen, which I found among some discarded ma-
terial some years ago, is without any indication of locality, but
was in all probabilit3' taken by Mr. Morrison ; it is a male, the
fifth ventral being short and broadly truncate, with a small feeble
sinuation at the middle of the truncature. I do not think that it
could by any possibilit}^ be the male of the preceding species,
which is known to me only hy the female.
DOLICHOISOMA iSteph.
The American type of this genus has no vestige of elytra! epi-
pleurse, the lower edge being acute and without a submarginal line
even toward base. This peculiarity necessitates its isolation
from all other generic groups of the tribe.
The tarsal claws are stout and strongly developed, the inner
.having a large corneous internal dilatation in basal half, which is
598 Coleojiterological Notices, VI.
continued to the apex by the rounded membranous appendage,
the latter leaving a small part of the tip of the claw free ; the
outer claw has the inner corneous dilatation extending far be3'ond
the middle, but the appendage forms merely a membranous ter-
minal margin ; the apical portion of the outer claw is more pro-
longed and arcuate than the corresponding part of the inner claw.
The tibiiB are altogether devoid of external spinules, but are
clothed sparsely throughout with long erect and stilt' black hairs,
and the pronotum has no trace of a submarginal line. The body
is extremely elongate and subcylindrical, differing vcr^' much in
facies from an}- other iy\iQ. of the tribe.
Two species may be assigned to this genus as follows, fovei-
collis serving as the type of the above remarks : —
Prothorax one-third wider than long 1 . foveicollis
Prothorax nearly twice as long as wide 2. teiiiiiforiuis
This genus seems to occur principall}' on the eastern slopes of
the Rocky Mountains from Texas to Hudson Bay, but probabl}-
entered the American continent by way of Siberia.

which I have seen, has a very large and deep anteriorly arcuate
excavation at the apex of the fifth ventral, the bottom of the ex-
cavation gradually smooth, level, polished and glabrous poste-
riorly, with a rectilinear and transverse posterior margin, which is
less apical than the lateral lobes of the segment ; the genital seg-
ment is broadly sinuate at apex throughout its width, flat, with all
but an abruptly limited lateral area pale and subcoriaceous. The
allusion to cinereous hairs by LeConte, in referring to the vesti-

European D. linearis in form, according to Dr. Horn ; I have seen
no representative, and the above statements are taken from the
original description.
Melyrini.
This tribe is but poorly represented in the United States by a
single small genus on each side of the continent. There can be no
doubt at all that both of these genera are ditferent from the Euro-
pean Melyris,and I have therefore thought best to give them sepa-
rate names; the}' are mutually ver}' distinct themselves, and may
be known b}' the following characters : —
600 Goleopterological Notices, VI.
Epipleiirre rather wide and parallel, extending to the sutural angles; last
joint of the maxillary palpi conoidal and graduallj- pointed; body very
coarsely and closely cribrate A ly liie l"is
Epipleune moderately wide toward base, gradxially becoming olisolete lie-
' hind the middle of the elytra; last joint of the maxillary palpi ()])li(iuely
truncate at apex; body sparsely punctured EtirelyiiiiK
Tlie species are generally quite rare and but few examples of
the majority of them exist at present in cabinets.
ALYMERIS n. gen.
This genus consists of small or moderate sized species, having
the integuments very coarsely, deeply and closely cribrate and the
epipleurffi rather wide, with their plane inclined slightl}' upward
and almost equal in width from the base to the sutural angles,
differing radicall}' in this respect from any other genus of the
family inhabiting the United States ; the eplpleurae are flat and
flnel}' punctate, and the margins become prominent toward apex,
the lower edge being strongly serrulate. The antennae are short,
the maxillary palpi somewhat small in size, the eyes well developed
and convex, the sides of the pronotum serrulate, the anterior tibite
devoid of spinules and the tarsi rather short, with the basal joint
quite distinctly shorter than the second, and the fifth joint of the
posterior fully as long as the three preceding together ; the
ungues are slender, with a feeble dentiform internal dilatation at
base, the appendages being obsolete. We have three well defined
species as follows : —
Elytra dark castaneous, the base and a small spot at tlie middle of each near
the apex pale testaceous; pubescence inconspicuous 1. basalis
Elytra uniform in color, blackish or ijiceous.
Elytral pubescence inconspicuous; prothorax strongly transverse and rap-
idly narrowed toward apex 2. cribrata
Elytral pubescence long and distinct; prothorax much less transverse and
feebly narrowed toward apex 3. Iloridaiia
The species of Alymeris are confined to the Atlantic and Gulf
regions of the continent from New York to Louisiana.

el^'tra are especially evident in the male, in which sex the fifth
ventral is broadly deflexed toward tip, with the apex somewhat
sinuate in the middle, and the genital segment thin, pale and cori-
aceous with its apex broadly and feebly sinuate, and its surface nar-
rowly and abruptly carinate along the middle. The description
is drawn from the female, and in the other sex the prothorax is
less transverse and less narrowed anteriorly, and the elytra rela-
tively shorter and more obtuse behind. Two specimens.

Florida (Key West). Mr. Schwnrz.
The male, serving as the type, has the fifth ventral ver}- short,
notdeflexed and broadly truncate at apex, with a rounded shallow
siuuation at the middle, the genital segment large and wide, feebly
arcuato-truneate throughout at apex and with a transverse ab-
rupt and flat-topped elevation on the surface at apex, the anterior
margin of which is arcuate and coincident in size and curvature
with the median sinus of the fifth segment, these characters be-
ing quite different from those of the two preceding species. In
the female the bod^' is still more strongly cuneiform, the elytra
longer, paler and more oval, the head and prothorax smaller, and
the fifth ventral short, fiat and broadly rounded. Two specimens.
ErRELYHIS n. gen.
The representatives of this genus differ very radically from
Alymeris in several particulars. The epipleuraj are very narrow
and graduall}'' become extinct far before the apex of the elytra;
the tarsi are long, filiform and very slender, with the basal joint
onl^- slightly shorter than the second and the latter fully as long
as the fifth. The antennte are better developed and are strongly'
serrate toward apex, and, finally, the fourth joint of the maxillary
palpi isobliquel}' truncate at apex, thus leading feebly toward the
next subfamily. The e^'es are lai'ge, prominent and basal , rounded
and with a small feeble anterior sinuation, but are glal)rous and
not distincth' less finely faceted than usual. The sculj)ture of the
bod^' is much finer and sparser than in the preceding genus, but
the lateral edges of the prothorax are quite as distinctly serrulate,
the edges of the elytra, however, being almost perfectly even
throughout. In one of the sexes there is, in all the 8j)ecies,an el-
Coleojjterological Notices, VI. 603
liptical area on each elytron near the apex which is polished and
impunctate, and of which there is no trace in the other ; in neither
sex is there any trace of costnliform lines on the elytra.
The species appear to be local and rare, and are distribnted over
the dr}' regions of the great interior basin west of the Rocky
Mountains ; the three known to me may be known as follows : —
Legs black, more or less paler distally.
Prothorax widest at or very near the base ; the sides convergent and feebly
arcuate throughout 1. speciilifer
Prothorax more arcuate at the sides toward base, and widest at a short
distance behiud the middle 2. atra
Legs pale flavo-testaceous throughout 3. flaTipes
In general appearance these species are remarkably homoge-
neous among themselves.
1. Eu. speciilifer n. sp. — Oblong, stoiit and strongly convex, dull,
the elytra shining ; under surface polished; body deep black throughout, the
legs black with the tibiae and tarsi gradually paler; antennje blackish, i^ale
toward base; pubescence very sparse, decumbent, moderate in length, dark in
color and entirely inconspicuous. Head small, about one-half as wide as the
prothorax, the sculpture shallow but scabro-puuctate, smooth toward apex ;
occiput feebly impressed along the middle, the frontal impressions obsolete;
epistoma short and wide, with a fine pale coriaceous margin; labrum short
and very broad, transversely rounded, rather dark in color; ej^es moderately
large; antennae a little longer than the prothorax, the two basal joints slightly
stout, the next two narrow, the fifth wider, six to ten still wider, rather com-
pact, strongly transverse, forming a broad pubescent and serrate club, the
eleventh moderate in length. Prothorax two-thirds wider than long, trape-
zoidal, the sides strongly convergent from base to ajjex and feebly, almost
evenly arcuate, the apex arcuate ; apical angles rounded, the basal obtuse;
disk densely and coarsely l)ut shallowly sculptured, the large umbilicate punc-
tures connected by anastomosing raised lines, forming still larger polygonal
meshes, the sculpture l)ut slightly stronger toward the sides. Elytra nearly
three-fourths longer than wide, distinctly wider than the prothorax, the sides
parallel and nearly straight; apex obtuse, the sutural angles broadly rounded;
disk sparsely punctate, the punctures gradually coarse toward base, fine pos-
teriorly, becoming denser and rugulose very near the apex. Abdomen feebly
punctulate, finely and sparsely pubescent, the legs rather long and .slender.

Utah (southwestern). Mr. C. J. Weidt.
The type is a male, and in that sex the fifth ventral is mnch
longer than the fourth and very broadh' and feebly sinuate to-
ward the middle of the apex. In the female the form throughout
is similar, but each elytron has an oval, subapical, polished and
fi04 Goleopterological Notices, VI.
more convex spot, and the fifth ventrnl has a veiy small circu-
larly rounded median nick, the genital segment being flexed up-
ward in plane, with a large triangular apical emargination. Other
than the median nick, the fifth ventral of the assumed female is
rounded behind, and, as the antennoe seem to be more slender
and the body larger in this specimen, — having the subapical
mirrors — it is probable that Dr. LeConte was correct in his iden-
tification of the sexes. Two specimens.

There is no representative before me of either this species or
the next, but from some drawings and notes made from the orig-
inal types a few 3'ears since, it is apparent that atra is nearly
identical in sculpture and pubescence to sjiecuHfer and JiavipeSy
but is rather narrower, more parallel and straighter at the sides
and a little more depressed ; legs as in speculifer. It differs de-
cidedly from both in the shape of the prothorax, which is more
rounded at the sides and widest at a much greater distance from
the base. Length 3.7 mm.; width 1.5 rnm.

This species exactly resembles ^ipecidifer, but is smaller and
with the legs pale flavate throughout and a little shorter. The
hind tarsi are very nearl}^ as long as the tibiie. In sculpture and
vestiture it is similar to sjyeculifer, except that the minute retic-
ulations of the elytra are more obliterated. Length 3.4-3.8 mm.;

In this genus the body is larger than in the preceding subfam-
ily, and clothed with long bristling pubescence. The ungual ap-
pendages are slender, equal, not as long as the claws and wholly

detached from them except at base, the tarsi moderate in length,
with the first and second joints eqnal, clothed with long erect
hairs above and long dense and coarse hairs beneath, and the an-
terior tibiae have a few long slender external spines. The maxil-
lary palpi are long, with the last joint large and in the form of a
right-angled triangle, abont twice as long as wide, the terminal
joint of the labial palpi being moderately dilated and transversely
trnncate at apex. The antennae are long, serrate, with the joints
elongate and acutely pointed internally at apex, and the eyes are
large, entire, sparsely setose and with the facets very large and
convex. The epistoma is large, bisinuate at base, coriaceous at
apex, and the labrum strongly transverse, arcuately truncate at
tip and with the surface somewhat impressed at the apex. The
epipleurre are moderate in width, flat and horizontal, with the
plane gradually inflexed posteriorly-, not attaining the apex of the
elytra.
The two species may be distinguished as follows : —
Eyes separated on tlie front by much less than twice their own width ; pro-
thorax very mucli narrower than the elytra 1 . testaceus
Eyes very much smaller, separated on the front by nearly three times their own
width ; prothorax almost as wide as the elytra 2. lecoiitei
The punctures of the head and pronotum are coarse, irregular,
sparse and unevenly distributed, and each is e;j;cavated in the
summit of an elevated tubercle, this form being evidently evolved
gradually from the asperate puncture, having its anterior margin
elevated.
This genus seems to be confined largely to the desert regions
of southern Arizona.

The single tj'pe before me is evidently' a female, the fifth ven-
tral being flat and ver^^ evenly- rounded behind. This species dif-
fers from testaceus in its stouter form, relativel}' much larger
prothorax, smaller head with very much smaller e^^es, and in its
closer and coarser punctuation.
Since this revision of the Mel^-ridtie was written, I have received
a tolerably complete set of the European genera, and find that
there is in general but little affinity with our representatives of
the famil}', tlie. American species being smaller, duller and much
less conspicuous insects as a rule. The American Dasytes and
Dolichosoma are evidentl}- congeneric with the European, or at
an}' rate very closely allied, but all our other genera, including
Alymeris and Eurelymis, are widely difterent from their most
closel}'^ related European analogues.

California (Los Angeles). Mr. River.s.
This species maj- be distinguished at once by the outline and
size of the prothorax, the sides being straighter and more con-
vergent from base to apex than in an}- other known to me. I
have before me onl^y a single male, another perfectly similar speci-
men being at present in the cabinet of Mr. Rivers.
T. riversin. sp. — Olilong-oval, convex, somewhat shining, pale brownish-
testaceous throughout, the knees minutely blackish; body clothed rather
sparsely with fine decumlient yellowish hairs, denser along the median line
and toward the sides of the pronotum; head, pronotum, sterna and femora
clothed in addition with long erect and conspicuous yellowish pile. Head
much less than one-half as wide as the prothorax, the clypeus narrowed at
Ijase, strongly concave, broadly arcuato-truncate at apex with the angles blunt
and rounded; antennie well developed, the club almost as long as the stem;
fourth palpal joint rather small, excavated, two-fifths as long as the antennal
club. Prothorax slightly less than twice as wide as long, broadly subangulate
at the sides just behind the middle, the angle rounded, the disk at this point
much wider than at base; apex two-thirds as wide as the base, broadly, cir-
cularly emarginate, the base arcuately lobed in the middle, the angles obtuse
but very distinct and only slightly blunt: disk rather coarsely deeply closely
and distinctly punctate. Elytra nearly one-fourth longer than wide, fully
two-fifths wider than the prothorax ; sides parallel, somewhat arcuate toward
apex, the latter very broadly arcuato-truncate; disk somewhat coai'sely,
sparsely, unevenlj^ and rather feeljly punctate, the sculpture finer and denser
along the suture. Pygidium feebly transverse, moderately convex, rather
finely but subrugosely punctate, sparsely pul)escent, subglabrous near the apex.

The description given above is drawn from the male, and the
female, judging from a specimen before me, is larger, wnth the
vestiture rather dense, the antennal club being oval and but

slightly move than twice as long as wide. In one respect riversi
differs from all the other members of this genus, the female being
more densely and conspicuoiislj^ clothed than the male ; it is pos-
sible, however, in spite of general facies, that this female does not
really belong to the same species, especially' as the basal angles of
the prothorax are broadly rounded. The hairs are much finer
than usual.
The two examples in my cabinet were kindly communicated by
Mr! J. J. Rivers, who possesses a considerable series.
These species should Ijoth be placed between ca^yenteri and
squamicoUis in the table previously published b}- me (Col. Not.
I, p. no).
It is impossible to properly associate the males and females in
this genus unless they be collected at the same time and place,
and it is consequently seldom prudent to base a species upon the
female alone.

Elytra one-half longer than wide, two and one-half times as long as the pro-
thorax and equal in width to the latter, the sides parallel and nearly straight;
apical two-fifths evenly ogival ; disk feebly uneven, strongly so toward apex,
where the coarse but rather sj^arse punctures bear somewhat long decumbent
hairs; punctures equally coarse throughout, the surface highly polished. Ab-
domen distinctly but sparsely punctate, the posterior legs long. Length 10.0-
11.5 mm. ; width 4.75-5.0 mm.
California (Farallone Islands). Mr. Fuchs.
By certain reflections tlie elytra seem to have each three fine
feeble and irregular raised lines in addition to the other sculpture.
Six specimens.
This species may be placed between viatica and eschschoUzi in
the table before mentioned, differing from the former in its coarse
sculpture, and from the latter in its much narrower form, polished
pronotum and many other characters. The Farallone Islands are
about thirty miles from San Francisco and are in deep water.
CCELIJS Esch.
A revision of this genus, together with a description of the larva
of G. ciliatuH, was given in the first part of the present series of
papers (p. 1T8), and the classification suggested below si based
largely upon the characters there employed. The species of
Ccelus are becoming moderately numerous, as the search for them
becomes more sj^stemaiic, and the six known to me at present
ma}^ be recognized by the following differential statement : —
Epistoma deeply sinuate, the sides anteriorly prominent though rounded.
Antennal club subquadriarticulate; i^ronotum sparsely and less coarsely
punctiite, with large impunctate areas; body very large....grossilS Csy.
Antennal club triarticulate ; pronotum coarsely and somewhat closely punc-
tate throughout; body much smaller globosus Lee.
Epistoma very broadly and feebly sinuate, the sides broadly rounded and not
anteriorly prominent.
Anxals N. Y. Acad. Sci., VIIL Sept., 1895.— 42

Pronotal punctures rather coarse, sparse and unevenly disposed, the surface
wholl}' impunctate in hirge areas before the middle of the disk.
areiiariu!« Csy.
Pronotal punctures coarse and rather close-set throughout the disk, though
l^nevenly distributed; body very much more broadly oval...latlls n. sp.
Pronotal punctures fine and sparse, somewhat evenly distributed over the
entire disk.
Body elongate-oval ; sides of the prothorax rather feebly arcuate.
ciliatus Esch.
Body short and ])road, the elytral asperities smaller, more distinctly de-
fined and more isolated; sides of the pi'othorax strongly arcuate; head
relatively smaller in size Clirtlllus n. sp.
All of the species have long coarse hair well developed along
the sides of the body, its function probabl}- being to maintain the
spiracles free from sand while burrowing.
C. lattlS. — Very broadlj* oblong-elliptical, moderately convex, polished,
'deep black, the legs dark piceo-rufous; palpi and antenniE paler, testaceous,
the labrum blackish; pubescence very short, sparse, yellowish, becoming
long at the sides of the body, short and very stifl' on the legs. Head not two-
■fifths as wide as the prothorax, coarsely and densely jiuuctured, less closely so
'on the epistoma, subimininctate toward base, the ei)istomal suture marked l)y
a deep transverse channel; apical sinuation very broad and feeble; antenna?
with the club three-jointed and feeble, the joints strongl.y transverse, the last
narrower as usual. Prothorax distinctly more than twice as wide as long;
apex one-half as wide as the base and deeply emarginate, the angles narrowly
xounded; sides strongly convergent from the base, arcuate, more strongly so at
"base, the basal angles obliterated; base transverse and almost rectilinear
throughout, with the usual fine coriaceous margin; disk coarsely deeply and
conspicuously punctate, the punctures generally rather close-set but uneven in
•distribution. Elytra barely as long as wide, about twice as long as the pro-
thorax, coarsely asperate and polished. Length 7.7 mm. ; width 4.8 mm.
California (San Diego).
At first sight this species might be mistaken for globosus, but
may be readily distinguished l)y its ver}' much more broadly
rounded form and very shallow epistomal sinus.
C. ciirtiillis. — Broad and oblong-oval, convex, polished, the elytra dull
toward apex, ))lack, the under surface and legs dark rufo-piceous, the trophi
and antcnntc still paler and rufous; surface glabrous except posteriorly and at
the sides of the body. Head rather small, barely two-fifths as wide as the pro-
thorax, roughly sculptured, the epistoma smoother, the suture deep; apical
sinus broad and feeble but stronger than in ciliatus ; labrum feeblj- sinuato-
truncate at apex. Prothorax short and transverse, slightly more than twice
as wide as its greatest length, the apex more than one-half as wide as the base;

sides strongly arcuate ; disk ratlier finely bnt strongly, sparsely punctate, more
densely so and somewhat scabrous toward the sides. Elytra short, not quite as
long as wide, equal in width to the prothorax, broadly rounded behind, the
asperities moderate in size, feeble toward base, closer and stronger toward
apex. Length 5.5 mm. ; width 3.4 mm.
California (San Francisco).
In ciliatus the prothorax is less strongly narrowed from base
to apex, not more than twice as wide as its maximum length and
is scarcely more than twice as wide as the head, and the elytra
are much more densely asperate. The proportions of the typical
ciliatus are 6.5 by 3.8 ram. I have carefully collected large colo-
nies of ciliatus, and believe that there are several forms which
are at least racial or varietal, some localities jdelding specimens
of a very much larger average size than others, with differences
in color, relative size of the head, sculpture and other minor fea-
tures.
EUSATTl'S Lee.
The following species is allied to duhius Lee, differing in its
smaller size and dull integuments : —
Ell. nanus u. sp. — Oblong-oval, strongly convex, dull, the pronotum
more shining and simply alutaceous, deep black, the antenna?, labrum, trophi
and tarsi dark rufous, subglabrous, each puncture bearing a very small de-
cumbent hair more noticeable near the sides of the pronotum, the hypomera
with long projecting hairs near the edges. Head one-half as wide as the pro-
thorax, strongly but not very densely punctate, the occiput impunctate; epi-
stoma moderately sinuate in the middle, the margin abruptly reflexed; antennae
slender. Prothorax twice as wide as long, the apex deeply emarginate and
three-fifths as wdde as the base, the latter deeply bisinuate, with the angles
posteriorly acute and prominent: apical angles advanced and narrowly rounded;
sides evenly and rather strongly rounded; basal margin with a fringe of very
short yellowish hairs; disk finely and sparsely punctate, narrowly reflexo-ex-
j)lanate at the sides, the punctures very minute and feeble toward the middle.
Elytra quite distinctly longer than wide, slightly more than twice as long as
the prothorax and barely as wide, subovate, the sides arcuate; apex broadly
rounded, the apical margin feebly subexplanate; disk slightly uneven, finely
simrsely and submuricately punctured. Epiplciirx narrow throughout, glab-
rous, sparsely wrinkled, deeply imi)ressed near the apex, the outer margin de-
scending. AhdoDien finely granulato-reticulate, convex, alutaceous, very finely
feebly and sparsely punctulate, each puncture l)earing a small decumbent hair;
legs sparsely and coarsely sculptured, the femora sparsely and coarsely pubes-
cent. Length 6.0-8.0 mm. ; width 3.4-4.8 mm.
California (Kern Co.).
614 Goleopterological Notice fi, VI.
One of the smallest species of the genus, distinguishable from
duhius hy its duller and blacker integuments, much less deeply
sinuate epistoma and by its relatively less transverse and abbre-
viated prothorax, which, in dubiiis, is about one-third as long as
the elytra. In nanus the sides of the prothorax are much less
convergent anteriorly than in diibius, and the general form of the
body is shorter and broader.
C03i'ISATTl'S n. gen.
Body oblong, subglabrous, the antennte long and slender, the
anterior tibi?e produced externally at apex and the base of the
prothorax transverse and straight, becoming feebly and poster-
iorly oblique near the sides
This genus is closely allied to Eusattus, differing in the trans-
verse and not bisinuate base of the prothorax ; it is founded upon
a single small species which may be described as follows : —
C. rectus n. sp. — Oblong, strongly convex, rather dull, blackish-castane-
ous in color, the elytral suture narrowly rufescent; legs dark rufous; anteunse
and tropin paler and more flavate; integuments subglabrous, the punctures
toward the sides of the upper surface bearing short inconspicuous hairs, the
outer edge of the epipleurte with a long fringe visible toward base, the under
surface of the the concave and longitudinally rugose propleurte without long
hairs; basal margin of the pronotum completely devoid of hairs, the apical
margin with an extremely short fringe. Head nearly one-half as wide as the
prothorax, convex and declivous, feebly impressed at the middle of the vertex,
finely but stronglj', sparsely punctate, more finely and densely so anteriorly,
the epistomal suture obsolete except at the sides, the apical margin feebly re-
flexed only at the sides, feebly sinuate at the middle; antenuse slender, not
quite as long as the head and prothorax, the joints elongate, third only slightly
longer than four to seven, club gradual and feeble, ninth joint longer than
wide, the tenth wider than long, eleventh oval and slightly elongate; nientum
flat, transverse, emarginate in circular arc; ligula angularly emarginate; last
joint of the maxillary palpi elongate, obliquely truncate at apex; eyes half
divided. ProtJiorar not (juite twice as wide as long, the apex deeply emargin-
ate and t^^•o-thirds as wide as the base; apical angles advanced but obtuse, the
basal right and slightly blunt, not prominent; sides evenly arcuate; disk
rather wider at basal third than at base, strongly, somewhat irregularly but
not denselj' punctate near the sides, finely' sparsely and feebly so toward the
middle; side margins very narrowly subexplanate and not beaded. Scutellum
triangular. Elytra longer than wide, barely as m ide as the prothorax and be-
tween two and three times as long, the sides feebly arcuate; apex slightly
produced and conjointly narrowly rounded; di.sk finely wrinkled and A\-ith
small moderately close-set, submuricate punctures. Abdomen polished, sparsely

but rather strongly punctured and somewhat pubescent; legs rather long, the
tarsi long and slender, the first joint of the anterior simple. Length 6.8 mm. ;
■width 3.3 mm.
Oregon (Squally Hill). Mr. Schwarz.
The epipleurffi are moderatel^y wide, inclined in plane, gradually
very narrow to the apex, sparsely punctate and glabrous.
CffiLOCIVEMIS Mann.
C sulcata n. sp. — Elongate and moderately stout, strongly convex, deep
black and dull throughout. Head one-half as wide as the prothorax, truncate
at apex, minutely feebly and sparsely punctate throughout; antennie about as
long as the prothorax, dull, minutely punctulate, each puncture bearing a min-
ute decumbent hair, third joint one-half longer than the fourth and scarcely
more than twice as long as wide, eleventh joint wider than long, very obliquely
pointed, the sensitive pores distinct and close-set. Prothorax not quite as long
as wide, widest at the middle where the sides are broadly angulate, thence
broadly arcuate and feebly convergent to the apex and slightly more conver-
gent and broadly, evenly and very feebly sinuate throughout to the base, the
the latter truncate and slightly narrower than the apex, which is also truncate
with the angles broadly rounded; basal angles slightly acute and prominent,
not rounded; disk extremely minutely but deeply punctate, the punctures
rather sparse, distinct under sufficient power and each lying within a large
feeble dent of the surface, the latter producing a very obsoletely rugose ap-
pearance. Elytra oval, not quite twice as long as wide, two and one-half
times as long as the prothorax and about one-fourth wider, arcuate at the
sides, the apex feebly produced and conjointly, evenly parabolic; disk finely
but deeply sulcate, the sulci minutely, not closely punctate, the intervals con-
vex, nearly smooth and extremely finely, sparsely punctulate. Leg>< long and
sparsely punctate; tibia? densely and compactly fulvo-pubescent within toward
apex as usual, the tarsi similarly clothed beneath. Length 26.0-28.0 mm.;
width 9.0-10.0 mm .
Utah (southwestern). Mr. C. J. Weidt.
This distinct species differs from punctata in its much larger
size, sulcate elytra and finer sculpture. According to Mr. Weidt
it occupies a very different station from punctata, one being found
only in the low sun-scorched plains, and the other in the high,
moist wooded regions.
BlAI'STINI.
There are several elements useful in the classification of the
genera of Blapstini, which, although apparently trivial in them-
selves, are undoubtedly sound with tlie limits of this particular
group of genera. The two to which attention should be parti-
616 Colropterological Notices, VI.
ciilarly drawn are : the form of the basal margin of the prothorax^
and the presence or absence of a fringe of seta3 along the lateral
edges of the body. A mere casual inspection of the numerous
species of Blapstmus, and of the otherwise evidently' distinct
though fewer representatives of Mecysmus, will show that the
bisinuate form of base is perfectly constant throughout the
former, and that the transversel}' rectilinear form is equally per-
sistent in the latter; consequently it must be evident that the
form of the base is of great importance, and the separation of
Cybotus and Aconobius on this feature alone would be more than
amply justified, irrespective of the profound ditierences in habi-
tus distinguishing both of these genera. Cybotus is however
further characterized by an abnormality of palpal structure, and
Aconobius by the presence of a dense fringe along the sides of
the body, which, in conjunction with its peculiar antennse, gives
it a very striking facies.
The marginal fringe is chiefly important in discriminating cer-
tain wingless genera, which constitute the division with connate
elytra and abbreviated scutellum. Its importance is demonstrated
by its absolute constancy throughout those polytypic genera
which happen to possess it, such as Ulus and Notibius, and there
can be no doubt that it is an important generic character, prob-
ably- developed by reason of changes in the life-habits of the
species. The characters here used to separate Nocibiotes, Toni-
bius and Tonibiastes are based upon types of elytral sculpture^
bodily facies and antennal structure, which are invariable through-
out the respective genera where enough species are known to test
their constancy, and it is probable that these genera Avill ulti-
mately hold good. Conibius, as here defined, is still somewhat
heterogeneous, containing three subgeneric types as noted below.
The genera of Blapstini ma^^ be separated as follows : —
Scutellum triangular, separating the elytra at base, the liiiul wings frequently
well developed and the anterior tarsi of the male dilated as a rule.
Base of the prothorax hisinuate.
Anterior tibiaj bent; vestiture dual in structure Tricliotoii
Anterior tibiic straight; pubescence simple.
Body generally oval, fimbriate at the sides; anterior tibiae produced
externally at apex I'liiS
Body usually oblong or oblong-oval, the sides not fimbriate; anterior
tibiie simple Blapstinus
Rise of the prothorax not bisinuate.
Coleopterological Notices, VI. 61 T
The base straight and as -svide as that of the elytra; hody broadly oval
and strongly convex Cy botllS
The base straight and narrower than that of the elytra; body elongate
and snbdepressed Mecy SillUS
The base evenly arcuate; body narrow and convex, densely fimbriate at
the sides Acoiiobius
Scntellum very short and broad, not entering the disk of the elytra; body
always completely apterous, the anterior tarsi never dilated in the male.
Prothorax not at all fimbriate at the sides.
Elytra not sulcate, the antennre stout, generally feebly and very gradu-
ally incrassate toward tip and without an abruijt club C'oiiibillS.
Elytra sulcate.
Antennae with an abrupt three-jointed club; elytral intervals convex
and asperate :Xocil>iotes
Antennae with a feeldy differentiated club; elytral intervals convex and
simply punctate; prothorax not narrowed behind Toiiibius
Antennae not described; elytral intervals acutely costiform; prothorax
narrowed behind Tonitoiastes
Prothorax densely fimbriate along the lateral edges.
Anterior tibiai narrow and non-fossorial ; body narrow and parallel.
Conibiosoina
Anterior tibiaj broadly triangular and compressed; body stout and oblong-
oval XotilJius
In this table the first five geneva and Conibiosoma remain with
the scope originally given them (Col. Not. II, p. 409). Aconobius
is fonnded upon Conibiosoma laciniata (Col. Not. Ill, p. 64),
and Tonibiastes has for its type Notibius costipennis Horn, re-
cently described from Lower California (Col. Baja Cal., p. 430).
The other genera are separately alluded to below.
The scheme of classification originally followed and more re-
cently maintained by Dr. Horn for this tribe, can scarcely be
regarded as coming within the domain of scientific taxonomy and
will ultimately have to be discarded.
CO^IBIUS Lee.
The species of this genus can be assigned to three subgenera,
which are widely distinct among themselves in point of general
appearance, as follows : —
Head parallel at the sides near the base; basal angles of the prothorax not
rounded and nearly right.
Body parallel, the elytra subeijual in width to the prothorax I
Body oval the elytra inflated and much wider II
Head prominent at the sides before the eyes; body stout, parallel and oblong;
basal angles of the prothorax obtuse and bluntly rounded Ill

IVOt'IBIOTES n. gen.
The species of this genus have a characteristic facies, which will
render their identification tolerably certain. The six representa-
tives known to me may be recognized b^' the following table : —

As far as known, this genus is confined to the arid regions of
southern California and Arizona.
IV. gracilis. — Somewhat narrow, moderately convex, dull, black, the
Tinder siirface rufo-piceous anteriorly; head rufescent toward apex; labrum,

margin; antennse scarcely as long as the head and prothorax, the second joint
quadrate, third rather more than twice as long as wide, fourth distinctly
elongate, five to eight eqrral, quadrate, nine to eleven abruptly much wider,
forming a parallel three-jointed club, the tenth moderately transverse, the
eleventh rounded and only just visibly narrower. Prothorax about one-third
wider than long, widest before the middle, the sides feebly arcuate, becoming
convergent and perfectly sti-aight toward base; apex broadly, circularly sinuate,
the angles obtusely rounded ; base transverse, subequal to the apex, strongly
bisinuate, the angles posteriorly acute and prominent; disk rather indistinctly
punctate, impressed at the posterior margin along the sinuations, not at all
explanate laterally, the punctures elongate-oval, shallow, distinctly separated,

Allied to granidatus Lee, but verjMuuch smaller, with much
finer and feebler pronotal sculpture and more deeply bisinuate
pronotal base, much more finely and sparsely sculptured pro-
pleurse and several other characters. It is described from the fe-
male, and has been compared with the corresponding sex of gran-
nlatus.

widest before the middle, the sides very feebly arcuate, becoming straight pos-
teriorly, the apex extremely feebly sinuate in circular arc, almost truncate,
the angles broadly obtuse and rounded; base equal to the apex, transverse and
feebly arcuate, becoming perceptibly sinuate near the angles, which are acute

disk rather coarsely, somewhat deeply and conspicuously punctate, the punc-
tures oval, well separated and distinctly defined, each bearing a very short
decumbent hair; interspaces rather smooth and alutaceous, obscurely granu-

The type is a male, having the anterior tibisB rather stout, bent
inward at apex and feebly prominent on the inner margin just
behind the middle, the abdomen feebl}- impressed, more coarsely
and closely punctate and more noticeabl}- pubescent in the middle
toward base, and the fifth segment broadly, feebly impressed.
This species differs from granulatus principall}'^ in its shorter
form, much shorter and stouter anterior tibia" in the male, coarser,
sparser and more distinct pronotal punctures, and in its decidedly
shorter third and narrower eleventh antennal ioints.

W. caudatllS. — Elongate-snboval, strongly convex, somewhat shining but
alutaceous, bhick; legs dark rufous, the antennas rufo-piceous; integuments
subglabrous, the pronotal punctures bearing minute decumbent hairs and the
elytral asperities bearing much inclined coai'se seta?, which are quite distinct
toward tlie sides. Head scarcely two-thirds as wide as the prothorax, slightly
transverse, with rather small, deep, distinct and separated punctures, the
apical emargination broad and subangulate; antennae long, fully as long as the
head and prothorax, the third joint much more than twice as long as wide and
rather longer than the next two, club only slightly abrupt, the penultimate
joints nearly as long as wide, the eleventh not narrower. Prothorax feebly
transverse, barely two-lifths wider than long, widest somewhat before the
middle but with the sides evenly and feebly arcuate throughout, not becoming
straight posteriorly, just visibly sinuate for a very short distance before the
basal angles which are right, not rounded and scarcely at all posteriorly prom-
inent, the base transverse, becoming very feebly sinuate near the basal angles^
apex quite distinctly narrower than the base, very evenly emarginate in cir-
cular arc, the angles distinct and only slightly blunt ; disk evenly smooth and
convex, finely, deeply evenly and somewhat sparsely punctate, the punctures
becoming gradually a little coarser, denser and less defined toward the sides;

twice as long as the prothorax, and, in the middle, one-fourth wider; sides
evenly arcuate; humeri broadly rounded, not exposed; apex acutely and grad-
ually ogival, each elytron produced in a short punctate and pubescent caudal
appendage; sulci deep, punctate, the intervals each with a single even series

tate, the propleurte longitudinally rugose ; legs rather long, the femora only
feebl;y*inflated toward aj)ex. Length 5.8 mm. ; width 1.9 mm.
Arizona.
The t3'pe of this distinct species is a female, the anterior tibiae
and abdomen being unmodified, the fifth segment of the latter
nearly flat and almost semi-circular.
^'. rubripes. — ^loderately slender and convex, strongly alutaceous,
black, the head rufescent anteriorly ; antennae infuscate in the middle; legs
rufous throughout ; integuments subglabrous. Head fully two-thirds as wide
as the prothorax, broadly, angularly emarginate at apex, densely punctate; an-
tennae not as long as the head and prothorax, the third joint about twice as
long as wide, the club but slightly abrupt, the tenth joint distinctly trans-
verse. Prothorax nearly as in caitdatns, the punctures slightly coarser and dis-
tinctly denser. Elytra scarcely more than one-half longer than wide, twice
as long as the prothorax and nearly one-fourth Avider, otherwise as in caudatus,
except that the apices are not at all produced posteriorly. Abdomen strongly
but not very closely punctate. Length 4.5 mm. ; width 1.7 mm.
Arizona. Mr. Wickham.
The type of this species is also a female, and is very closely
622 Coleopferoloc/ical Notices, VI.
allied to caudatus, (littering in the shorter, non-caudate elytra,
denser punctures of the head and pronotum, coarser abdominal
punctuation, shorter antennae and smaller size. The type is
from a locality in Arizona, widely different from that of caudatus,
and there is reason to believe that the caudal process in the latter
is as permanent and invariable a feature as in Eleodes caudifera
Lee; so there appears to be but little doubt of the validity of
the species.
TOXIBIIS n. gen.
The only species which can 1)e referred to this genus for the
present are sulcatus Lee, and alternatus Cs,\. The latter of these
species is in no sense an abnormal state of the former, of which
I have before me an ample series, no specimen of which displays
any tendency to vary in the direction of the peculiar specific
characters of alternatus. In alternatus the size is materially
greater than is CA'er attained by s»/cfl/».s,and the sculpture of the
pronotum is very much coarser.
NOTIBirS Lee.
This is a natural and distinctly characterized group of species,
in which the body is stout, oblong and convex, with a dense de-
cumbent fringe along the lateral margins of the prothorax, and
broad fossorial anterior tibial in both sexes. The four species
may be distinguished at once b^' the following strongly marked
and constant characters : —
Third antenna] joint elongate, gradnally and feel)]y obconical from base to
apex.
Sides of the pronotum broadly reflexo-explanate pilbei'lllus Lee.
Sides not at all or very narrowly subexplanate.
Head parallel at base; apical angles of the prothorax obtnse but evident
externally ; pronotum coarsely and deeply' punctate.
siibfiiti'iatiis Csy.

BOLITOPHAGINI.
The North American genera of this tribe seem to be more con-
veniently divisible into primary groups upon the basis of anten-
nal structure than by the structure of the eyes, and, the occur-
rence of an interesting new type in the Pacific coast region, af-
fords an opportunity to outline their distinguishing characters as
follows : —
Anteniife lO-jointed, the third much elongated, tenth perfectly free, the ninth
not emarginate; eyes not divided; prothorax broadly pednncnlate at base.
Bolitotliei-us
Antennae 11-jointed.
Eleventh joint free, the tenth broadly arcuato-truncate at apex; eyes com-
pletely divided.
Pronotum tuberculose; elyti'a with coarse interrupted ridges.
Bolitopliagiis
Pronotum punctate; elytra Avith fine continuous ridges Eleates
Eleventh joint set partially within the emarginate apex of the tenth and in
close contact throughout the width ; eyes not divided.
Mentum not carinate; elytra with series of tubercles Iflegeleates
Mentum with a strong compressed keel; elytra with tine even ridges.
Eledoua
Eledona appears to be of doubtful occurrence in the United
States, but is introduced for comparison.
MEGEI.EATES n. gen.
Body thick, subcylindric. Head deeply inserted, the apical
margin not reflexed except feebly toward the sides, continuously
and evenly arcuate, obtusely prominent laterally before the eyes,
the latter moderately coarsely faceted and one-half divided. Max-
illar}' palpi subcylindric in form, the joints in close mutual con-
tact, polished and sparsely punctulate, the last cylindro-conical
and nearly twice as long as the third. Antennal grooves beneath
the eyes moderately deep. Antennte with the third joint only
slightly' elongate. Prothorax not in the least pedunculate at base.
Scutellum oval, truncate at base. Epipleurre horizontal, rather

wide and of almost equal width from the base to within a short
distance of the apical angles, where they become rapidly nar-
rowed. Anterior coxje moderately separated, the intermediate
more widely, the process of the mesosternum slightly tumid and
anteriorly excavated to receive the prosternal process ; posterior
separated by two-thirds of the coxal width, the abdominal process
broadly rounded. Met-episterna narrow and parallel. Legs short
and stout; tibite tricarinate externally; tarsi thick, the last joint
of the posterior as long as the preceding three.
]fl. sequoiariiiii n. sp. — Oblong, stronglj^ convex, opaque throughout,
black and glabrous. Head not coarsely but strongly scabro-punctate, Avith a
tuberculiforni elevation above each eye; antennie as long as the width of the
head, the three outer joints broader and minutely, denselj' pubescent, joints
before the club triangular, ninth and tenth strongly transverse. Profhorax
fully twice as wide as long, twice as wide as the head, the apex three-fourths
as wide as the base; sides evenly arcuate throughout and strongly crenulate;
apical angles advanced; base arcuate, becoming obliquely sinuate toward the
sides; disk rather abrujitly and broadly reflexed toward the sides, covered
with coarse separated tubercles, sulcate along the middle, the sides of the sul-
cus becoming carinate anteriorly in the male but simply tumid in the female.
Elytra parallel, subetjual in width to the prothorax, about two-fifths longer
than wide, broadlj- but evenly rounded at ape.x; side margins slightly promi-
nent, more so and cariniform toward apex, stronglj- crenulate, not at all re-
flexed; disk vertical at the sides, having regular series of rather coarse, close-
set, opacjue tubercles, the intervals each with a series of coarse and rounded
punctures separated by small tubercles; third, fifth and seventh series of
tubercles more i^rominent, the third especially so toward the summit of the
apical declivity, which is almost vertical in profile. Abdomen strongly and
closelj' punctate, the legs less coarsely, strongly and very densely punctate.
Length 6.5-7.0 mm. ; width 3.4-3.() mm.
California (Big Trees, Calaveras Co.). Dr. Blaisdell.
The sexual differences are very feeble, the male having the sides
of the pronotal sulcus more prominent and laminate toward apex,
as stated, and the general form of the body sensibly shorter. Sev-
eral specimens.
ANTHICID.E.
The following studies were undertaken largely for the purpose
of identifying and naming a considerable number of nondescripts,
which have been accumulating for many years, but, at the same
time I have become much interested in the general grouping and
classification of the genera, points which were left in a very un-
Coleopterological Notices, VI. 625
satisfactory state by LeConte and Horn, the very important and
obvious abdominal structure of the Xylophilin;i?, for example,
being completel}' overlooked by these usually acute observers.
The last revision of the American species, as a whole, was pub-
lished by LeConte more than forty A'ears ago, and is at present
of course very incomplete.
The sexual characters of the abdomen are in some groups
verv pronounced and in others feeble, differing greatly in general
character in the various genera and usually varying distinctly in
degree from species to species. In the Eur^-geniini the external
modifications are conspicuous only in Retocomus, and in that
tribe the intromittent organ is of a somewhat simple type
throughout. In Pedilus (=Corpliyra) and Macratria, genera with
distinct tarsal modifications, the external characters are feeble,
while the intromittent apparatus becomes marvelously complex.
These facts tend to prove still further that primary sexual char-
acters, when differing distincth' in type, may in certain cases be
quite as valuable in defining genera as any other structural modi-
fication.
The well known scarcity of individuals in many parts of the
series, as for instance in the Eurygeniini and Xylophiliufe, results
in all probability, chiefly from the fact that we do not know the
habits of these insects, which are very diflferent from the epigeal
Anthicini. It is possible that each species ma}^ appear in abun-
dance only at certain very limited seasons or on certain individ-
ual trees, as is known to be the case with a number of longicorn
groups of suppossed excessive rarity.
The Anthicidse may be divided into two important subfamilies
as follows: —
Abdomen composed of five free segments; tarsus with the penultimate joint
lobed beneath; tibial spurs generally distinct; labial palpi minute.
Anthicini
Abdomen composed of four free segments, the first formed of two amalgamated
somites with the suture sometimes indicated; tarsus witli the antepenulti-
mate joint lobed beneath, the penuHimate small; tilnal spurs generally
obsolete; labial palpi witli the last joint large and more or less dilated.
XVLOPHILINiE
Anthicini.
This subfamily may be divided into five tribes by the following
-characters : —
G26 Goleo2oterological Notices, VI.
Tarsal claws appendiculate ; eyes emarginate and finely faceted; neck wide;
maxillary palpi slender Nkm atoplini
Tarsiil claws not appendiculate.
Neck wide; eyes large, finely faceted and generally emarginate; basal seg-
ment of the abdomen not elongate.
Prothorax constricted at apex and margined at base; tarsal claws simple
or with a feeble dentiform dilatation at base EURYGENIIXI
Prothorax not constricted at apex, margined at base; tarsal claws with
a pointed lamelliform tooth internally at base, the apical part
abruptly bent Pedilini
Neck narrow; eyes not emarginate; prothorax constricted at apex.
Eyes large, oval, rather finely faceted; basal segment of the abdomen
elongate ; claws somewhat as in Pedilini M ACRATKIIXI
Eyes small, rounded, not emarginate, generally coarsely faceted; basal
segment of the abdomen not conspicuously elongate; claws simple.
Anthicixi
The first four of these tribes are arboreal in habit, the fifth epi-
geal. The Xj'lophilinse are arboreal, and it might therefore be
considered best to put them at the head of the familj^ instead of
immediately succeeding the Anthicini ; but it will be observed
that the Xylophilinse differ quite as much, if not more, from the
Eurygeniini as from the Anthicini, and it is therefore immaterial
where we place them. Again, the apical constriction of the pro-
thorax, which is such a constant and peculiar feature of the An-
thicini, is even more strongly developed in the Eurygeniini, and
is altogether obsolete in Xylophilin;^ ; the eyes are finely faceted
in all the larger forms constituting the first tribes, coarsely so in
Anthicini and generally very coarsely so in Xylophilinse ; so, con-
sidering the question from all points of view and having due re-
gard to the small size and less highly developed structure, as
shown by the amalgamated basal segments of the abdomen, it
seems more fitting to place the subfamily at the end of the series.
Concerning the erection of a distinct family for the Xylophi-
linae, as proposed by Mr. Champion, I regret to have to disagree.
The sclerites of the under surface, especially near and between
the middle coxa^, are identical in Anthicus and Xylophilus, ex-
cept that the mesosternal [process in the latter is not quite so
long, and there is, besides, a certain indefinable habitus possessed
by the two t^^Des in common, which seems to show that they
should not be Avidely separated.
Coleopterological Notices, VI. 627
Nematoplini.
The exceedingly rare Neinafoplus coUaris Lee, is at present
the onl_y species assignable to this tribe. The hind tarsi are fili-
form throughout, with the third joint simple and cylindrical ; this
very exceptional structure in the first genus of the subfamily be-
ing similar to that of Mecynotarsus, which I have placed at the
end. The tarsal claws are by no means cleft, as stated b}' Le-
Conte and Horn (Class. Col. N. A., p. 410), but are simple and
thickened or subdentate internally at base, where there is attached
a long slender minutel}" pubescent appendage, which almost equals
the claw in length; besides this remarkable appendage, there is a
distinct bisetose onychium between the claws.* The last antennal
joint is not unusually elongate, and the feeble apical constriction
of the prothorax does not extend laterally upon the flanks.
EURYGENIINI.
The genera composing this tribe are somewhat numerous, and
are confined entirely to the new world ; those known to me at
present may be distinguished as follows : —
Last joint of the antennae not noticeably elongate.
Eyes narrowly and distinctly emarginate.
Tenipora prominent; antennte filiform; maxillary palpi large, with the
last joint triangular Retocomiis
Tempora not prominent; antennas serrate and very long; maxillary palpi
small, filiform, the last joint cylindrical and not much longer than the
preceding Hastorenius
Eyes truncate or broadly and feebly sinuate; antenna; filiform.
Tempora well developed and prominent.
Eyes large; spurs of the hind tibiae short; last joint of the maxillary
palpi long and cultriform Stereopalpu!^
Eyes much smaller; spurs of the hind tibiie long; maxillary imlpi
greatly developed, very broad, the joints triangular Pergetus
Tempora not prominent; eyes very large; tibial spurs short.
£iirygeiiiiis
Last joint of the antennie much elongated Bactrocei'US
These genera are all North American, except Eurygenius,
which is confined as far as known to Brazil. The third joint of
the hind tarsi is triangular, not dilated and not membranous or

noticeably produced beneath. Bactrocerus contains a single
species from Lower California, which I do not have before me at
present; the pronotum is covered with coarse sparse and crescen-
tiform granulations, and has the vestiture coarse and sparse.
RETOCOmUS n. gen.
The North American species hitherto regarded as Eur3^genius,
differ so greatly from the South American type as defined by La-
Ferte, that it seems impossible to avoid defining a distinct genus
to receive them, and for this the above name is suggested. In
the type of Eur3genius the eyes are not emarginate and the
tempora are not at all prominent, besides many other diflferences,
notably in the organs of the mouth. LeConte and Horn state
that in Eurygenius muriniis — which is the only species which I
have not been able to examine, — the eyes are practically not
emarginate; this species seems also, from the original description
of LeConte, to depart markedly in vestiture from the others^
and future study may possibly prove it to be genericall}'^ distinct;
it occurs in Georgia and Alabama. In all the other representa-
tives the emargination of the e^'es is deep and distinct, not essen-
tially differing in consftnetus.
Our species may be defined as follows : —
Elytra each with five narrow vittie of fulvous puhescence wildi Lee.
Elytra with uniformly colored pubescence, Avhich is uneven in distribution.
Species of the Atlantic region niiiriniis Hald.
Species of the Pacific coast.
Prothorax with a strongly developed arcuate apical lol)e and a deep
broad constriction; elytra vaguely subvittate coiistrictlis Lee.
Prothorax with a smaller apical lobe and finer constriction; elytra
unevenly and sparsely marmorate with condensed white pubes-
cence, not at all subvittate.
Abdomen clothed with long shaggy pubescence, the elytra about
twice as long as wide gratiis n. sp.
Abdomen clothed with much shorter, more recumbent pubescence;
elytra distinctly more than twice as long as wide.
decorelliis n. sp.
The two sexes of ivildi seem to differ a good deal in general
form, the male being smaller, more slender aiid with subcunei-
form elytra ; in the female the elytra are broad and parallel.
All the species which I have examined have the basal joint of
the bind tarsi strongly contorted at base, a character which is

tribe which have iinemarginate eyes. In Mastoremus, which also
has emarginate eyes, it is very noticeable, and there raaj- possibly
be some correlation between these characters.
R. s;ratllS. — Eather narrow, black, the femora and tibiae toward base
slijihtly rufescent, sparsely clothed with complex pubescence, consisting of al-
most evenly distributed suberect short gray hairs, widely scattered long erect
l)laek setoe, and decumbent coarse white hairs in uneven widely scattered spots
on the elytra. Head as wide as the prothorax, about as long as wide, the eyes
large and prominent, separated by but slightly more than their own width on
the front, the latter coarsely, densely punctate and coarsely shaggy; antennae
slender, moderate in length; palpi moderate. Prothorax as long as wide,
rounded on the sides at apical third, thence feebly convergent and broadly,
evenly sinuate to the base; apical constriction fine, extending across the dorsal
surface; apical lobe short, three-fifths as wide as the base; disk not canalicu-
late, not very coarsely, densely punctate and dull, the punctures longitudin-
ally coalescent. Scutellum clothed with white hair. Elytra scarcely more
than tmce as long as wide, fully three-fourths wider than the the prothorax
and rather more than three times as long ; sides subparallel and nearly straight
to apical fifth, then almost evenly rounded, finely dehiscent toward apex, the
sutural angles right; disk polished, coarsely, deeply punctate, the punctures
separated by about their own diameters. Under surface shining, moderately
closely punctate and clothed with long hair, quite sparsely on the abdomen.
Legs moderate, the femora gradually stout; tibia; roughly asperate externally;
hind tarsi fully three-fourths as long as the tibiae, with the basal joint strongly
contorted at base and much longer than the fourth. Length 8.4 mm. ; width
2.2 mm.

The two specimens are perfectly similar males, having the fifth
ventral deeply excavated in the middle throughout the length,
the sides of the excavation prominent and lamellate posteriori}'.
R. decorellllS. — Moderately slender and convex, black, the tibiae, ex-
cept at base and apex, and the basal parts of the femora feebly suffused with
rufous; elytra with a feeble violaceo-aeneous metallic lustre; vestiture nearly
as in (jratun but still somewhat sparser, the elytral spots rather more numer-
ous and more evenly scattered. Head densely punctate and dull, the eyes
large and prominent, separated on the front by quite distinctly more than
their own width; antennae slender, filiform, the basal joint stoutest, but little
longer than the head and prothorax. Prothorax noticeably longer than wide,
rounded on the sides anteriorly, subparallel and broadly, feebly sinuate thence
to the base, the apical node short, nearly two-thirds as wide as the base; disk
(lull, moderately coarsely, deeply, longitudinally punctato-rugose, the sculp-
ture but little concealed by the vestiture. Scutellum clothed as usual with

longer than the last. Length 8.8 mm. ; width 2.4 mm.
California (Marin Co.).
The single male before me represents a species allied rather
closely to gratus, but differing in a number of well marked struc-
tural characters. The elytra are more elongate and more finely
pubescent than in gratus, and, although the large deep excava-
tion of the fifth segment is nearly similar, the copulatory spicule
differs decidedly, being much stouter, with a broad dorsal im-
pression extending only slightly be^'ond the middle of its length ;
in gratus it is more attenuate, with the dorsal channel fine, ex-
tending almost to the extreme tip and gradualh* disappearing.

The unique type is a male, having very feeble abdominal

and other genera of the tribe. This form is absolutely ditferent
from that seen in Pedilus and Macratria.

This well known genus is somewhat rich in species, occurring
throughout the United States ; I have separated the eleven known

Vestiture uniform in distribution and in general tint.
Head equal in width to the prothorax.
.Species of the Atlantic regions ; pronotal sculpture finer and less dense,
the elytral punctiu'es coarser and more distinct.

nus may be better placed in the present genus, but a renewed
inspection of the palpi would be necessary- to decide.
The species of Stereopalpus are ver^- uniform in structure
throughout, and have comparatively feeble sexual characters ;
the male has a small terminal and densely punctate genital seg-
ment, which is but little protruded. The eyes are broadly and

tinctly shorter and narrower than the prothorax, almost as long as wide,
densely opaque, the surface concealed; eyes separated by a little more than
twice their own width on the front; tempora rather more prominent than the
eyes and about two-thirds as long; antennse slender, but little longer than the
head and prothorax, the stouter basal joint not paler. Prothorax slightly wider

Indiana.
In its larger, more globose and less distant eyes, shorter, less
I>rominent tempora and generall}^ more shining surface, this
species departs from the common type of the Pacific coast and
approaches mellyi. It differs from mellyi in the small nuclei of
pubescence scattered irregularly and indefinably over the elytra,
and in the smaller, more strongly and coarsely sculptured and
more deeply canaliculate prothorax. Four specimens, with very
feeble sexual characters.
S. impressicollis. — Black and moderately stout, the elytra shining
through the vestiture, which is rather sparse except in the condensed spots;
legs and antenna; black throughout. Head densely puuctato-rugose and dull,
the vestiture dense ; eyes moderate, separated by distinctly more than twice
their own width, the tempora fully as prominent as the eyes and about one-
half as long; antenna; moderately slender, about two-fifths as long as the body.
Prothorax as long as wide, rounded on the sides antei'iorly, sinuate thence ta
the basal margin, which is scarcely dilated and defined throughout dorsally by
a distinct groove; apical constriction fine, distinct; canaliculation fine, deep,
impressed; lateral oblique impressions strong; sculpture rugose. Etytra
slightly more than twice as wide as the prothorax, a little more than twice as
long as wide, quite perceptibly wider to apical fourth, then parabolically
rounded, narrowly and gradually dehiscent behind, the sutural angles obtusely
rounded; humeri broadly, evenly rounded, the impression feeble; punctures
coarse, close, the surface subrugose; interspaces shining and not distinctly
punctulate. Abdomen minutely, extremely densely punctate and i)ubescent.
Length 6.3 mm. ; width 2.0 mm.
California (Hoopa Val., Humboldt Co.).
The single specimen is a female, and, if my memory serves, was
taken ver^- nearly or quite at the same time and place as the single
male of indutus, so that for some time I considered them to be

the two sexes of one species. I find, liowever, that the spotted
vestiture is a constant asexual character in other species, or at
least is not at all characteristic of the female, and, besides this,
these two specimens differ structurall}- to a considerable degree,
the entire form of the body being different; finally, the deep me-
dian sulcus o{ impressicoUia exists only as a vestige in indutus.
S. subalbicaiis. — Narrow, convex, the elj'tra polished, the histre but
little concealed by the scanty cinereous vestiture, except in the dense and
widely scattered spots; color of body and antennae black throughout, the
femora black, rufescent at base; tibise rufous, the apex black; tarsi black, the
basal joint feebly rufescent except toward apex. Head but slightly wider than
long, relatively coarsely, very deeply and denselj' rugoso-punctate ])ut not dull,
the vestiture rather short and only moderately dense; eyes separated by a little
more than twice their ^^•idtll, the tempora equally prominent and al)out one-
half as long; antenna; rather stout, filiform, distinctly less than one-half as long
as the body. Prothorax barelj' as long as wide, with outline nearly as in the
preceding species, sculptured almost like the head, the median sulcus strong,
impressed; lateral impressions very feeble; surface unusually convex. Elytra
evidently less than twice as wide as the prothorax and distinctly more than
twice as long as wide, the sides parallel, parabolic in apical fourth, scarcely at
all deliiscent on the suture even at the extreme apex; humeri broadly rounded
to the prothorax; punctures coarse, deep and close, the sculpture rugulose by
anteriorly oblique light; interspaces not appreciably punctate. Abtlomen
closely punctate 1)iit unusually shining, the punctures smaller and more super-
ficial. Legs rather long. Length 5.5 mm.; width 1.5 mm.
California (San Francisco). Mr. Dunn.
The smallest species of the genus and quite distinct from any
other, differing from impressicoUis in the feeble pronotal impres-
sions and color of the legs, and from (juftafus in its much smaller
size and more slender form. The single specimen is a male.
PER<wETrS n. gen.
This genus is founded upon Earipjenius campanulatiis of Le-
Conte, which occurs in the Island of Vancouver. As a genus it is
remarkably distinct from Retocomus in the structure and vesti-
ture of the legs, in the comparatively small, uneinarginate eyes
and much more developed maxillary j)ali)i. The i)ronotum is
deeply and peculiarly sulcate along the middle ; the sexual charac-
tei's affecting the fifth segment of the abdomen are feeble, and the
tibial spurs are long, all of which characters are foreign to Reto-
comus. The tibia? are cylindrical, and are clothed with short stiff
inclined pubescence, very uniformly throughout, while in Reto-
Coleo2:)terological Notices, VI. 637
<;omus they fire slightly irregular, strongly hispid externally, and
clothed with long sparse flying hairs in addition to the more re-
cumbent pubescence.
Pedilini.
This tribe contains but one genus within our territories. Ped-
ilus is said by Mr. Champion to be the same as Corphyra Say,
and, if so, our numerous closely allied and prettily colored species
will have to be called by that generic name. The third joint of
the hind tarsi is produced beneath in a short membranous lobe.
Our species of Corphyra have been recently reviewed hy Dr.
Horn (Tr. Am. Ent. See, 1871, p. 228, and 1. c, 1883, X, p. 305).
The male intromittent organ in Pedilus is complex, the etterent
duct lying in a dorsal excavation of the protective sheath, which
is furnished with two internally barbed lateral appendages at
apex. This structure is interesting when compared with the
equally complex organ of Malporus, of the Anthicini, where, how-
ever, the efferent duct lies in an excavation on the xinder surface
•of the sheath, these extremely important conditions being com-
pletel}' reversed.
Macratriini.
The following genus is the onl}- one of this tribe which is
known at present : —
MAC RATRIA Newm.
The genus Macratria departs widely from all foregoing types
of the Anthicinae in its ver}^ slender neck and elongated basal seg-
ment of the abdomen. The last three antennal joints are elon-
gate and the third joint of the hind tarsi has a short membranous
lobe beneath. In the structure of the oedeagus it differs radically
in type from the Eurygeniini, but is to a great extent homolo-
gous with the Pedilini. The tibial spurs are rather remarkable in
structure, being densely <;lothed with minute inclined setai, the
outer spur much stouter than the inner.
The four species represented in my cabinet may be thus de-
fined : —
Last joint of the antenna? subecjual in length to the two preceding conil)ine(l
in l)oth sexes.
Head minutely and remotely ])unctate; legs dark in color... coilfusa Leo.
638 Coleopterological Notices, VI.
Head less minutely and very closely punctate; legs pale.
Elytra tinely, densely sculptured and pubescent; protliorax more rapidly
narrowed anteriorly than posteriorly iiiiirina Fab.
Elytra coarsely and much nu)re rugosely sculptured, more coarsely and
sparsely pubescent; prothorax equally ol)li(iue anteriorly and poste-
riorly, widest at the middle ovicollis n. sp.
Last joint of the antennse but slightly longer than the penultimate; body red-
brown throughout, the head more oblong Iiruiinea n. sp.
Judging hy the Hgure of M. linearis Newm., reproduced by La-
Ferte, it seems impossible to associate it with any species of Ma-
cratria now known. If rediscovered it will probably prove to be
the type of a distinct genus, w'hich must be called Macratria, the
species here tabulated to be then known as Macrarthria Er.
H. OTicollis. — Moderately slender, black, the legs, antenna; and palpi
ochreo-testacous, the femora feelily nubilate with Inown near the apex and the
ninth and tenth antennal joints darker toward base; puliescence moderately
dense, yello-\\-ish, readily removable. Head as long as wide, broadly subtrun-
cate at base, paler toward apex, the eyes separated on the front b}' rather less than
twice their own width ; antennae about as long as the head and prothorax, fili-
form, the ninth and tenth joints subequal and each one-half longer than the
eighth, second very nearly as long as the third. Prothorax two-lifths longer than
wide, one-half longer and just visibly wider than the head, the sides evenly
and strongly arcuate from apex to base, the base, immediately in advance of
the basal depression, strongly rounded, rather more prominent than the basal
bead and more feebly sculptured; disk feebly, evenly convex, very densely
punctato-rugose. Elytra at base one-third wider than the prothorax, a little
more than twice as long as wide, the sides straight and very feebly convergent
from base to apex ; disk rather shining when denuded, roughly and seriately
asperato-rugose, the intervals finely, densely punctato-rugose. Under surface
minutely, densely punctate, the legs stout. Length 4.5 mm. ; width 1.0 mm.
New York.
The male type has the fifth ventral not longer than the fourth,
broadly, transversely truncate at apex and very broadly, feebly
impressed on the disk almost throughout the width. I have for
the present associated with the t3'pe two females which, however^
have the prothorax widest at apical third.
M. Iiriiiiiiea. — Moderately stout, the male more slender, dark red-
brown, the head paler, rufous, the antennie, palpi, anterior and intermediate
legs paler, ochraceous; hind legs piceous; sculpture throughout fine, very
dense, the surface not shining; pubescence short, very dense, yellowish-cine-
reous in color. Head oblong-oval, as long as wide, finely, densely punctate,
truncate at base; eyes separated by twice their own width; tempora strongly
Coleoplerological Notices^ VI. 639
rounded to the neck, one-half as long as the eye and much less prominent; an-
tennte about as long as the head and prothorax, slender and filiform, the last
three joints much stouter, eighth much shorter than the seventh, second and
third equal in length, the former slightly the thicker. Prothorax one-third
to two-fifths longer than wide, subequal in width to the head, widest at
apical two-fifths, finely, densely punctate and rugose, the surface even;
basal margin strongly marked at the sides. Elytra one-third to nearly one-half
wider than the prothorax, nearly two and one-half times longer than wide,
slightly cuneiform, rather narrowly and conjointly rounded at tip; humeri
strongly, evenly rounded to the prothorax ; disk striato-punctate, the suture
strongly margined. Under surface minutely, densely punctulate, very finely,
densely pubescent. Legs thick; basal joint of the hind tarsi quite distinctly
longer than the remainder. Length 3.9-4.9 mm. ; width 0.8-1.2 mm.
Texas (Austin).
The male has the fifth segment unimpressed, a little longer than
the fourth and transversely truncate at apex, the middle of the
truncature slightly produced in a minute rounded projection. In
the female the fifth segment is much longer, strongly narrowed
from base to apex, the rounded apex feebl}^ sinuate in the mid-
dle, and the surface broadly impressed ; the second ventral has at
each side a strong transverse excavation along the basal margin
which is wanting in the male. The male intromittent organ is
ver}' intricate, having two thick complex lateral lobes, with ex-
ternal pubescent appendages, and a very slender central organ,
till of equal length ; it is therefore almost of the same general
type as in Pedilus.
I took a good series of this interesting species in the valley' of
the Colorado of Texas, in June.
Anthicini.
The components of this extensive and widely distributed tribe
a,re active ground beetles of predaceous habits. The various
genera have not been considered very pronounced or sharplj^ de-
fined hitherto, but the discovery of certain extraordinarily devel-
oped and diversified modifications of the mesosternum and its
parapleurae, enables me to delimit those which occur within our
territories with much confidence. These wonderful structures by
some singular chance seem to have thus far escaped observation,
although in several cases the}' are so radical as to be obtrusively
evident, the edge of the large expanded mesosternal plate, for ex-
ample, being occasionally i)rominent from a dorsal point of view
640 Coleopterological Notices, VI.
in the reentrant fingle at the base of the prothorax, where it
bristles with a sparse fringe of long cilia.*
As these characters are unusual and abnormal, a perfect con-
stancy of form or extent is not to be expected, and the occurrence
of transitional groups, in which the mesosternum is variously de-
veloped according to the species, might be anticipated. In point
of fact, we actually find that in some generic groups, the form and
extent of the mesosternum are as constant as the thoracic process
of Notoxus — another abnormal structure, — or even more so, but
in a few others, such as Vacusus and especially Hemantus, they
become variable subgenerically, but still onl}^ to a slight extent
specificall3^ The occurrence of these remarkable structures has
alone compelled me to increase considerably the number of gen-
era, but it should be mentioned that in every case the validit}' of
the genus is confirmed b}' other marked peculiarities of special
structure, and also by general habitus.
The North American genera of the tribe may be outlined
as follows : —
Pronotiim without an elongate corneous process near the apex 2
Pronotum with a large anteriorly porrect subapical process 11
2 — Anterior coxal cavities closed behind, to a certain degree, by an oblitera-
tion of the usual posterior emargination; prothorax strongly constricted be-
hind the middle, the depression extending more or less feebl,y across the
dorsal surface; mesosternum extending in one large unbroken plate to
the sides of the body, the lateral edges ciliate and largely visible from
above 3
Anterior coxal cavities widely open behind, their corneous floor broadly and
deeply emarginate posteriorly 4
3 — Head olilong, the eyes very small and anterior; body densely and minutely
sculptured and pubescent DilandillS
Head more oval or sulKjuadrate, the eyes larger and submedian in i)osition;
body small and su))glabrous Foi'inicilla
4 — Penultimate tarsal Joint generally just Aisibly dilated, deeply excavated
or longitudinally grooved above and feebly lobed beneath, the last joint
inserted discally and far from the apex; elytra entire or nearly so,
* It is true that LaFerte alludes at some length to this character under the
description of Formicomtts hporinus (Mou., p. 93), but in such a way as to
show that he failed completely to grasp its meaning, or to realize its far-reach-
ing taxonomic value in the tribe, his description proving that he even failed to
examine the under surface of the insect at all, and I am some^vhat surprised
to find that the character is passed over even more lightly by Mr. Champion
in his description of F. nracUipes (Biol. Cent. -Am er., IV, 3, p. 220).
Coleopterological Notices, VI. 641
rounded behind; eleventh joint of the antennne simple; last joint of the
maxillary palpi secui'iform or somewhat broadly triangular 5

forming a point between the broad epiaternum and the coxae 9
6 — Prothorax deeply constricted or abruptly narrowed behind the middle, or
near basal thi rd 7
Prothorax not constricted at the sides, except occasionally feebly and near the
base, the sides oblique and straight 8
T — Tlie constriction extending deeply- across the dorsal surface; antennse
thick and subnioniliform Toinodei'llS
The constriction not extending across the dorsal surface.
Antennas long and slender; anterior lobe of the prothorax rounded.
Last joint of the maxillary palpi small or moderate, securiform.
Mesosternum extending in a highly polished plate far toward the
sides of the body, its outline rounded; body extremely densely
punctate without trace of erect sette Baillius
Mesosternum less extended laterally, its outer margin oblique and
straight; thoracic constriction strong; body very sparingly punc-
tate and bristling with long erect tactile setae Malpoi'US
Mesosternum less extended laterally, its outer margin sublougitudinal,
scarcely at all oblique and evenly arcuate; thoracic constriction
feeble and more posterior; body rather sparsely punctate, feebly
pubescent and devoid of long erect tactile setse ; head truncate at
base iVatliictis
Last joint of the palpi very large and dilated, isosceles LappilS
Antennie much shorter; anterior lolje of the protliorax trapezoidal, widest
near the apex; last joint of the maxillary palpi moderate in size, securi-
form; mesosternum as in Malporus and Lappus TliicanilS

constricted just before the liase; vestiture simple Antliicus
Prothorax relatively small, not quite as long as wide, sinuate at the sides
posteriorly; elytra relatively larger and longer; vestiture duplex.
Sapintiis
Pronotum abruptly declivous and flattened anteriorly, the head strongly tri-
angular; body stout and convex; metasternum short Aiiiblytleriis
■642 Goleopterological Notices^ VI.
lO — Mesostcrnum and its parapleurse as in Anthicvis Taiiarthriis
11 — Tarsi sliorter than the tibia?, the penultimate joint slij^htly dilated.
IVotoxiis
Tarsi very long and filiform, longer than the tibiie, the penultimate joint
evenly cylindrical and not at all thicker Mecyiiotai'sus
It is unfortunate that in tliis lineal arrangement Tanarthrus
lias to intervene between Amblyderus and Xotoxus, Init it would
be still more out of place among the genera allied to Tomoderus,
■where it must otherwise be placed.
DILAXDIITS n. gen.
The two species separated under this name, together with
Formicilla, are peculiar in having the acute side-pieces of the
l)rosternum behind the coxse more inwardl}' prolonged than in
Anthicus, so that thev coalesce at or near the middle, thus closing
the coxal cavities. In the other genera, as I find b}' dissecting
numerous divergent forms, the inferior flanks of the protliorax
form angular inward projections behind, which are widel}' sepa-
rated by a deep emargination of the common coxal floor, and the
^oxal cavities are consequently l)roadly open. The mesosternum
in this genus extends in one extremely large unbroken })olished
plate from side to side of the body, and is largely visible from
above in the reentrant humeral angle ; the prominent lateral
•edges of this plate bear a sparse fringe of long stitf bristling set.v.
In the form of the head Dilandius resembles Ochthenomus to
a great degree, the outline being oblong-suboval, with the eyes
small and anterior.
Our two species are very slender ant-like insects, distinguish-
able at once from Malporus and Lappus by the form of the head,
disposition of the elytral vestiture, and b}' the fact that the lateral
constriction of the prothorax extends across the dorsal surface,
giving rise to two convex lobes.* They may be known as fol-
lows : —
Dorsal constriction of the prothorax strong; white piibescent fascia of the
elytra oblique 1. iiiyi'niecops
Dorsal constriction feeble ; pubescent fascia transverse 2. iiiiictis
* In the second group of Lappus there is a large dorsal gibbosity near the
l)ase of the pronotum, but this is a true protuberance, and is not produced by
a dorsal extension of the lateral constriction; in gibbithorax and others of this
^oup, there is no transverse depression before the protuberance.
Coleopterological Notices, VI. 643
The representatives of this genus are very rare in collections,
and scarce!}' anything can be stated in regard to their trne geo-
grapliieal distribution.

FORIHIC ILLA Leo.
The very small polished and sparsel}' setose species, for which
this genus was erected by LeConte (Ann. TjVC. Nat. Hist.,
N. Y., Y, p. 1-^2), certainly cannot be associated with the large
forms of totally- different habitus, which include the types of
Formicomus Laf., nor can the}' be placed with Anthicus, as sub-
sequentl}- suggested by LeConte (Proc. Acad. Nat. Sci., Fhila.,
1852, p. 94), because of the remarkable structure of the meso-
sternum. The onl}- course left, therefore, is to regard them as
•constituting a distinct genus.
The anterior coxal cavities are closed behind b}- an extension
of their corneous floor, and, in scitula, the median line of the floor
is produced behind in a slender cusp-point which, however, does
not project posteriorly further than the lateral lobes, from each of
which it is separated b^- a small deep rounded emargination. The
fourth palpal joint is only moderately large, triangular and ob-
liquely truncate.
The species are confined to the extreme south of the United
States, from the Atlantic to the Pacific, extending also into
Mexico, but the approximate southern limits of range are not at
present deterniinal)le.
Our four species may be known as follows : —
Coleopterological Notices, VI. 645
Anterior lobe of the prothorax t>lobular or at least as long as wide.
Elytra short, much narrowed )>ut almost completely unimpressed on the
disk near the base, and devoid of shorter subdecumbent hairs.
1. scitula
Elytra longer, less narrowed at base, but distinctly impressed behind the
omoplates, having short sparse subdecirmbent hairs in addition to the
long erect setic 2. iniluda
Anterior lobe larger, wider than long.
Elytra pale, with the humeri and two broad fascia; of black ; head (quadrate,
subtruncate at base 3. evaiiescens
Elytra black, with tAvo narrow pale fasciae, one near the base, the other be-
fore apical third ; head narrower, more elongate and more rounded at
base 4. gilensis
The species are very homogeneous in point of size and others
will undoubtedly be discovered ; those above outlined are divisi-
ble into two subgeneric groups, the first represented by scitula
alone, as shown hx antennal structure, and the second by the last
three species.

California (Yuma). In the male the fifth ventral is evenly
rounded behind, unmodified and very much shorter than the two
preceding together, the genital segment small, parabolic in out-
line, the apex with a small but rather deep and very acutely at-
tenuate notch, each of the small lobes inflexed and almost meet-
ing at apex ; the copulatory spicule is long, extremely slender
and gradually finely pointed, the under surface very feebly im-
pressed along the median line, more strongly toward base. This
species, although congeneric, is remarkably distinct from scitula.

Arizona (Tu9son).
The single male, from which this description is drawn, has the
copulatory spicule almost completel}^ protruded ; it is of singular
form and very simple structure, three-fifths as long as the entire
abdomen, slender, nearly straight in profile and gradually acutel}'
and extremely finely attenuate from Ijase to apex, the sides
straight; the slender eflierent duct beneath is much shorter, and
is only partially and basally sheltered in the inferior excavation
-of the spicule, the latter scarcel^^ serving as a protective sheath.

TOMODERIS Laf.
The species of this well marked genus veiy closely resemble
each other in general appearance. They are robust and convex
in bodj^, with stout, moniliform, strongl}^ incrassate and perfoliate
antennse, deeply segmented prothorax, subserial elytral punctu-
ation, moderately developed mesosternal plate and stout clavate
femora.
The hind coxae are widely separated by a short, broadly rounded
projection of the first abdominal segment, the tibial spurs appar-
ently wholly obsolete, and the fourth palpal Joint moderately de-
veloped, triangular and obliquely truncate. The e3'es are rather
small, moderately convex and somewhat coarsel}' faceted. The
transverse dorsal constriction of the pronotum is generally more
or less distinctl}'^ and coarsely sculptured at the bottom, and the
basal marginal line is wholl}^ obsolete; the apical collar is also
obsolete or extremely rudimentary, the head being in close con-
tact with the anterior lobe of the prothorax, and the neck some-
what wider as well as shorter than in Anthicus.
Our three species may be thus distinguished: —
Anterior lobe of the pronotum without an impressed median line.
Elytral punctures distinct throughout, becoming very graduallj' coarser and
confusedly subserial in arrangement toward base 1. abbreviatufii
Elytral punctures very fine, becoming abruptly coarse and distinctly seriate
in basal third or fourth ; apical segment of the abdomen longer in both
sexes 2. coiistrictus
Anterior lobe broader and generally more narrowly rounded at the sides, hav-
ing a feebly impressed median canaliculation which does not attain the
apex; elytra shorter, the sculpture nearly as in abbrcrintus, the pubescence
denser 3. inipressuliis
Tomoderus, as here understood, extends throughout the United
States, east of the Rocky Mountains and f^xr into Mexico, but
does not occur near the Pacific coast.

Indiana, Kentuek3' and Iowa. This species has been well de-
scribed by LaFerte, though I have never seen an example in;
which the punctures are completel}' confused toward the elytraU
base ; it is especially abundant in the Mississippi valley, while-
the following is the common species along the Atlantic coast.
The fifth ventral in the male is short, only one-third longer than
the fourth, narrowly subtruncate at the middle of the apex, the
edge thence oblique and straight nearl}^ to the sides, then rounded
to the base, the genital segment large and broad, pale and sub-
coriaceous, transverselj^ convex throughout the width and sub-
truncate at apex. In the female the fifth ventral is much longer,
two-thirds longer than the fourth, and is evenly rounded in cir-
cular arc throughout.

Similar to the preceding in general form and sculpture, but
with the elytra a little shorter and stouter and pale only in basal
third or fourth, with the punctures very fine, becoming abruptly
coarse and more distinctly seriate in the pale area. Length 2.4-

New York, Rhode Island and Michigan. The male has the fifth
ventral fully three-fourths longer than the fourth, transversely
truncate in median fourth at apex, the edge thence oblique and
straight to near the sides, then gradually rounded to the base, the
genital segment transversely, evenly convex and truncate at
apex, nearly as in interrivptus. In the female the fifth ventral
is fully three-fourths longer than the fourth, and is evenly and
somewhat parabolically rounded behind.
3. T. inipre*«sullis n. sp. — [Moderately stout, convex, liif^lily polished,

but not impressed at base; angles rounded; tenipora thence straight and diver-
gent to the eyes, which are rather small and slightly prominent; antenna' very
thick, fully as long as the head and prothorax, the penultimate joints strongly
transverse. J'rothorax just visibly narrower than the head, a little longer than
wide, deeply and acutely constricted at basal two-fifths, the constriction with
coarse cellular sculpture; anterior lobe very strongly transverse and distinctly
impressed along the median line. Elytra short, barely one-half longer than
wide, twice as wide as the prothorax in the male, slightly wider in the female,
slightly inflated at the middle, obtuse and transversely arcuate at apex, the
humeri rather widely exposed and rounded to the prothorax; basal impressions
and omoplates obsolete. Ahtl(»iien finely and rather closely punctate. Ler/s

North Carolina (Asheville).
The male sexual characters are nearly as in the preceding
species, the fifth ventral in the male being about one-half longer
than the fourth. In the female it is three-fourths longer than the
fourth, and more evenly rounded.
This species is allied to inlerrujotus, but may be distinguished
by the shorter, more unicolorous and more densely pubescent
elytra, impressed pronotum and somewhat smaller size. Three
specimens.
BAULIITS n. gen.
The body is rather narrow, convex, subopaque fiom the minute
and very dense punctures and extremely short fine decuml)ent
pubescence. Head subhexagonal, rather longer than wide, convex,
the sides behind the eyes convergent and nearly straight for a
long distance, the base broadly, feebly arcuate; eyes rather large

fine line. El^'tra more than twice as wide as the prothorax,
nearly twice as long as wide,distinctl3" expanded behind, the sides
broadly arcuate; disk transversely impressed near the base, the
depression traversed by a perfectly even parallel-sided, narrow and
abruptly defined transverse fascia of pale yellowish-white. Legs

joint of the posterior tarsi scarcely as long as the remainder, the
third short. Mesosternum expanded in a broad, highly polished
impunctate and glabrons plate, its outline at the sides rounded
and not furnished with long seta^, the episternum tumid, visible
from above, discontinuous in level with the met-episternum, the
iiies-epimeron ver3" narrow and subobsolete.
The type is Anthicus tenuis of LeConte (Ann. Lye, N. Y., Y,
p. 153), ver}^ abundant in the desert regions from western Texas to
southern California. The male has the fifth ventral much longer
than the preceding, rather strongly rounded at apex and unmodi-
fied, the sixth or genital segment coriaceous, emarginate in the
middle at apex, the copulatory spicule abruptly narrowed and
prolonged for a short distance at apex.
MALPORl'S n. gen.
In this genus the head is more strongly and circularl}' rounded
behind than in Lappus, and the sculpture and vestiture of the body
are peculiar, the elytra being ver3^ coarsely and unequally punc-
tate and bristling with long erect tactile setse. The last joint of
the maxillarj' palpi is moderate in size, and ver^- different from
the form occurring in the genus Lappus. Our species ma}^ be
distinguished thus : —
Elytra! puuctures distinct throughout the disk, though fine and remote toward
apex, closer and. coarse before the middle; posterior part of the disk but
slightly convex in profile; elytra but slightly narrowed toward base.
Prothorax very strongly constricted; body throughout more s^sarsely punc-
tate, the elytra without an apical pale spot 1. foi'inicarilis
Prothorax much less strongly constricted; punctures throughout denser;
elytra more parallel, the pale fascia less basal, each having an apical pale
spot; antennje longer and more slender 2. ciiictlis
Elytra devoid of distinct punctuation, except in the subbasal impression
which is strong.
Elytra elongate, the pronotum not impressed 3. properus
Elytra much shorter and more strongly convex in profile, the pronotum
feebly impressed along the median line 4. blaildtis
The corneous copulatory sheath of the male is elaboratel3' modi-
fied in this genus as described below, the efferent duct lying in a
cavit}' of the under surface. In comparing this structure, which
is the prevailing type throughout the Anthicini, with the pro-
jecting " spike " which I have previously noted in Hymenorus
(Col. Not. Ill, pp. 70, 89), the homology seems to be evident,

and the oi'gan there alluded to is probably the mobile efferent duct
bent downward from the protecting corneous sheath.

Rhode Island to Iowa. The type above described is a male
from the shores of Narragansett Bay, and diflTers slightly from
some of the western specimens in its smaller size, rather narrower
head and sparser punctuation.
The redeagus of this species is very complex. The genital
segment is short and simple, with a rounded shallow sinuation at
the middle of the apex subequal in extent and degree of curva-
ture to the lateral lobes. The ert"erent duct is extremely long
and slender, lying in the wide deep inferior opening of a long
broad sheath, which is parajlel-sided and flattened dorsalh^ for
the greater i)art of its length, but narrowed near the apex,
where it becomes split into three lobes of equal length, the

point ; tlie slender intromittent duct proper, lying within the widely
open under surface of this sheath, is cylindrical and feebly,
broadly constricted at apical fourth, failing to attain the tip of
the acute median process of the sheath by a fifth or sixth of its
own length ; it is gradually and feebly bent downward toward
apex. The entire organ as protruded in this specimen is rather
more than one-half as long as the abdomen.

This species differs from formicarius in its larger size, longer,
more filiform, scarcely incrassate antennae, much larger and more
prominent eyes, denser punctures of the pronotum and elytra, the
latter being more parallel and scarcely at all dilated behind the
middle, and in coloration, cinctus being pale vufo-testaceous in
color, with the elytra blackish except toward base, and with an
apical pale spot which is always wanting in formicarius ; it also
differs in the position of the transverse pale fascia, this being sit-
uated more nearl}^ at basal third than fourth. In the present
species the omoplates are ver}' prominent, but the transverse im-
pression of the elytra behind them is obsolete. Length 3.7 mm.;

The strong basal impression and minute punctuation of the
elytra, larger eyes and slender, scarcely incrassate antennae, will
readily distinguish this species from formicarius. The trans-
A'erse fascia is more basal than hi formicarius, being at about basal
fifth, and the sexual characters of the male are very different, the
genital segment being emarginate almost throughout its width,
the bottom of the emargination l)roadly trisinuate; the hind tibiae
are bisinuate in curvature. The erect sparse setaj of the elytra
are very long and conspicuous.

This is one of the most conspicuous and interesting anthicides

Hubbard and Schwarz.
LAPPrS n. gen.
The species composing this genus have heretofore been re-
garded as a simple section of Anthicus, but the structure of the
mesosternum and prothorax, as well as their peculiar general habi-
tus, demands a separation of them from that unwieldy complex.
They are ver}^ numerous in the United States, especially in the
arid southwestern country, as shown by the results of recent
skillful collecting in those regions.
This genus differs from the others more closely allied, in the
great development of the fourth joint of the maxillary palpi, and
the long tactile setse, which are so conspicuous a feature in Mal-
porus, are completely wanting; the punctuation is very fine and
dense as a rule, also in striking contrast to that genus. In re-
gard to the cedeagus, I have seen no specimen with the apparatus
snfficientl}' protruded for examination, and I have not had
enough time or duplicate material to make dissections, but it
is doubtless somewhat complex in structure.
It is scarcely possible that Lappus can be identical with the
South American Ischyropalpus of LaFerte, for neither Lappus
obscurus nor L. sturmi (elegans) seems to have suggested to the
author an alliance with Ischyroj^a^iKS jjei'plexus (Mon., p. 142),
but in case obscurus and perplexus should prove to be congeneric,
there is no reason why the name Isch^-ropalpus should not be re-
stricted to either sericans or trigonocephalus (1. c, pp. 143, 146),
as the first is probablj^, and the second certainly', generically dif-
ferent from perpilexus.

Texas (El Paso); Arizona (Seligman and Peach Springs).
I took the single male tj'pe at El Paso some j^ears ago, and the
Arizona specimens, collected b}' Mr. Wickham, do not seem to
differ, the male from Peach Springs being simply' a little more

The sparse punctuation, narrower form and still longer, more

by the greater extension of the head behind the eyes and parallel
elytra, which are abruptly and broadly rounded at apex and not
gradually narrowed behind the middle. From cursor, in addi-

narrower and less transverse anterior lobe of the prothorax and
much sparser punctuation throughout, and, from alacer, by its
narrower prothorax, with the punctures denser along the middle
anteriorlj', narrow and strong post-scutellar impression and
several other characters. The sexual characters of the single

California. The male has feebly marked sexual characters, as
in cursor and alacer. This description refers to the typical
nitidulus, but among my large series from various parts of the
State, it is eas}' to distinguish a number of more or less well
marked varieties, some of them so marked that there can be but
little doubt that there are several closel3' allied species included ;
they all agree, however, in having the head comparatively small
and strongly, asperately punctate, and the anterior lobe of the
prothorax widest near its base. Most of them have the basal
parts of the elytra paler, the completelA' black forms, which may
be regarded as typical, being rather rare. One specimen is from
southwestern Utah.

Oregon (Portland).
The type of this species is unfortunateh' a female, but its el^'tra
are mucli shorter tlian in any of the forms of nitidulus which I
have seen, and the antennal joints are also much shorter. As it is
unique, it is impossible to pronounce any definite opinion con-
cerning the normality of the el^'tral asperities, and the}' may possi-
bly be due to accident in this individual. I have, however, a good
series collected in the Hoopa Val., Humboldt Co., Cal., which
agree fairl}^ well in form, color and structure with the Oregon
type, but which have the elytra smooth; they may be regarded a&
conspecific until more individuals of the form selected for descrip-
tion can b(! obtained.

In the male the fifth ventral is unmodified, very broadly rounded

has kindly sent me a specimen of the closely allied backianus
Chmp., from Mexico. The erect hairs mentioned in the descrip-
tion are very short and only distinct toward apex, as usual in
this genus. This species differs from backianus and tumidicollis
in its coloration and rather stouter form. The above description
is translated from the original.

The few closely allied species forming this generic group are
somewhat intermediate between Lappus and Anthicus, but evi-
dently cannot be associated with the former because of their much
shorter antenna and small fourth joint of the maxillary palpi,
which has the form of a right-angled triangle, and, from Anthicus,
they differ in the lateral oblique extension of the mesosternum ;
from both of these genera they differ conspicuously in the form
of the prothorax. Those known to me may be mutually separated
as follows : —
Head evenly and almost circularly rounded hehiiid the eyes.
Antenuic rather strongly but gradually clavate, the penultimate joints
transverse.
Punctures of the elytra rather close-set, especially toward the suture,
those of tfie pronotum very densely crowded toward base..l. texanus
Punctures of the elytra rather coarser and decidedly more distant, those
of the pronotum moderately dense toward base; size a little larger.

The species of this genus resemble each other in general habi-
tus and color to an extreme degree, and if it were not for the
readily observable modifications of the sexual apparatus, it would
frequently' be impossible to pronounce an}' definite opinion as to
their true status. In all of them there can be observed two
feeble transverse and very vague elevations near the basal mar-
gin of the pronotum.
The intromittent apparatus of the male is ver^- simple in struc-
ture, when compared with the homologous parts in Malporus.

The large series before me is from Galveston, Texas, and repre-
sents without much doubt the true texanus of LaFerte, which was
unknown to LeConte.
In the present species, which has been full}^ and accurately de-
scribed by LaFerte, the male has the fifth ventral but slightly
longer than the fourth, broadly rounded at apex, just visibly
sinuato-truncate for a short distance in the middle, with the ad-
joining surface feeblj-, transversel}' impressed, the genital segment
very feebly sinnate at tip, with the surface feebly and transversely
impressed. The male intromittent organ consists of a superior
corneous flattened and very shallow sheath, nearly one-half as
long as the abdomen, the short basal part of which is parallel at
the sides, the remainder very elongate, bent downward, with the
sides straight and gradually convergent throughout to the apex,
the latter slightly dilated in the form of a small flattened sub-
circular button. The intromittent duct proper is partially en-
closed along the under surface of the sheath ; it is membranous
or feebly coriaceous in structure, and fully as long as the protec-
tive sheath, from which it can be bent downward ; it is somewhat
distorted in the specimen examined but appears to be of a sub-
cylindrical form.

California seacoast from San Diego to San Francisco. The
apex of the abdomen is generally pale, and, in the male, the fifth
segment is distinctly longer than the fourth, rounded and not at

impressed along the middle, and gradually just visibly reflexed
toward tip, the genital segment with a small feeble and circularly
rounded apical sinuation, and a transverse discal impression, the
apical edge fringed with stiff hairs.
In this species the male intromittent organ is quite different
from that of texanus and mimus ; it is not quite so long, and
the dorsal corneous sheath has the sides nearly straight and
feebly convergent from the base almost to the apex, where it be-
comes abruptly narrowed and very feebly bent downward, the
narrow ligula short, subparallel, obtuse but not distinctly en-
larged at apex. The intromittent duct proper, lying beneath the
sheath, is slender, simple, coriaceous and extends slightly beyond
the apex of the sheath.

California, (near San Francisco).
The single male before me indicates a species which is appreci-
ably larger than calif ornicus, and the sexual characters are quite
dirterent. The fifth ventral is short and but slightl_y longer
than the fourth, its apex broadly, just visibly sinuate, and its disk
unmodified ; genital segment deeply, angularly emarginate in the
middle at apex, the emargination but slightly' more than twice as
wide as deep, the disk with a large deep and transversely oval
impression, and the posterior edge fringed with stiff, inwardl}^ di-
rected cilia. In this specimen the extreme tip only of the copu-
latory sheath is exposed, but this is much broader and more ob-
tuse than in californici(i<, and there is, in addition, a slender thin
fillet at each side of the sheath-apex, of which I can find no homo-
logue whatever in that species.
VACrSlTS n. gen.
The members of this genus are small, narrow and usually pol-
ished, sparsely punctate and pubescent species, of peculiar facies,
but not unremindful of some of the various forms of Anthicus.
They also resemble Anthicus in autennal, oral and crural struc-
ture, but difier completely in the entire conformation of the meso-
sternum, as detailed in the table of genera. They present three
tjqjes, quite distinct in appearance and environment, represented
b}- lastas, 7ii(ji'ilt(lus and formicetorum, the first inhabiting the
Southern States from Florida to southern California, the second
peculiar to the true Pacific coast fauna, and the third to the desert
regions of the Sonoran province. The latter is remarkable, in
addition to its peculiarities of facies, in that its closely allied
components are m^'nnecophilous in habit, the S3'mbiosis how-
ever probably not being complete.
The species ma}^ be separated as follows : —

This well known species is distributed through the Southern
States bordering the Gulf of Mexico. It is suHiciently constant
in form and structure, but varies considerably in color. In the
darker form, named Ihoraeicus by LaFerte, the elytra are almost
black ; they are never entirely black, however, for u})on close in-
spection in a good light, there will always be seen a narrow line
along the suture and a fine transverse fascia at basal fourth and
apical third of reddish tinge. The prothorax is always red. I
am disposed to agree with LaFerte' in considering bifasciatus
Sa\',as allied to hrfu^, and not to t-ern'mix, as conjectured by Le-

This species is allied rather closely to Isefus, but differs in its
smaller size, narrower form, black prothorax and elytra, and in
the male sexual characters. The vestiture of the upper surface is
similar to that of Isetus, the elytral hairs very short but rather
coarse and becoming still smaller toward apex.
In this section of the genus the genital or sixth segment is
peculiarly modified, the median emargination of Anthicus becom-
ing a deep cleft, the two lobes thickened and l)ent strongly down-
ward, the tips iuHexed and individually emarginate ; the intromit-
tent organ is extremely slender and elongate, finely channeled be-
neath, the apex gradually finely acuminate and slender, and bent
downward. In the present s|)ecies merely the tip is abrui)tly and
feebly bent downward, while in biefKs the spicule is gradually

shorter and mutually more distant. The present species is rep-
resented in my cabinet by two specimens, and the description is

characters given in the table, but bj' the more abrupt and notice-

these joints form a true, though feeble, five-jointed club, while in

The unique t^pe is a female from the Levette cabinet, and is in

HEMAiXTUS n. gen.
The general habitus of Anthicus Jloralis is peculiar and aber-
rant in its smooth subglabrous surface, in the occurrence of a
.subapical modification of the pronotum — always a significant
structure in this family, — in its stout antennae, robust legs
with (luite distinctly clavate femora, and other features, so that
its systematic position among the other species has always been
uncertain. When we add to these disparities of structure the
Coleopferological Notices, VI. 683
singular modification of the mesosternum, tliere can be but little
doubt that the correct solution of its taxonomy is the erection
for it of a distinct genus, and at the same time, the radical varia-
tions in this mesosternal structure show beyond peradventure
that several distinct species have been confounded, not only in
this country but in Europe.
The material in my cabinet can be resolved into the four fol-
lowing well characterized specific forms : —
Mesosternum greatly dilated at tlie sides, extending with rounded outline
more than half way between the coxse and the elytral humeri, its outer
margin beiiring a close fringe of long fine decumbent hairs ; pronotum con-
stantly Avith a small feeble double tubercle in the middle near the apex.
(Subgenus I) 1. floralis
ilesosternum very much less developed laterally, intervening obli(iuely be-
tween the cox;c and episternum but only slightly more so than in Anthi-
cus, its outer margin not timVuiate ; pronotum constantly devoid of any
trace of the subapical tubercle. (Subgenus II)
Prothorax more finely and sparsely punctate, feebly and more obtusely con-
stricted near the base.
Prothorax very narrowly and strongly rounded at the sides near the apex.
'i. enodis
Prothorax broadly rounded at the sides anteriorly, much more feebly ob-
]i<jue and gradually narrowed thence to the subbasal constriction.
3. scenicus
Prothorax more strongly and closely punctate, the posterior constriction deep
and almost rectangular, the basal margin much wider and more strongly
expanded 4. rixator
The American Jloralia extends Avithout noticeable variation
over the entire country, but my material in the second subgenus
is not suflieiently extensive to enable me to pronounce any useful
opinion as to geographical distribution. This is however an in-
teresting subject, and well merits careful attention from those
possessing large series.

Indiana, Iowa (Keokuk), Texas (Galveston and El Paso) and
California (Lake Co). This common and apparently cosmopoli-
tan species has been thoroughly described by LaFerte, and may
always be recognized by the small double tubercle of the prono-
tum, which is not wanting in any specimen of the true JloraUs
which I have seen ; in some specimens the feeble depression be-
tween the tubercles is prolonged along the median line for a con-
siderable distance toward base. In the male the general form is
stouter, the head and prothorax especially being broader, and the
antennje apparently a little longer and thicker, but the mesostcrnum
and pronotal tubercle are not at all affected sexually. The mosi
remarkable external sexual difference relates to the form of
the pygi<lium, which, in the male, is vertical and strongly con-
vex, while in the female it is nearly flat, extremely oblique and
almost horizontal. It is not only probable that this is not
the MeJoe JloraJis of Linne, but quite possible that it may be dif-
ferent from the Anfhicus Jloralis of European authors, though
belonging to the same subgenus, for the length of the Euroix'.ui
insect as given by LaFerte* (3.0-3.5 mm.), is substantially greater
than that of the American representative, and LaFerte seems to
be very accurate and careful in his measurements.

The three specimens before me are females, and the species ma^^
be readily known from the others here described by the dull and
rather densely punctate head, deep constriction of the prothorax
and other characters ; the mesosternum, also, is apparently a trifle
more dilated at the sides. The base of tlie i)rothorax is much
broader and more dilated than in e)wdis.

Even in its restricted scope, this genus is still a large one and
to some extent heterogeneous, including as it does species pf
widely different facies, such as horridua^ haldemani and mari-
tiTnuii. They all agree, however, in sternal, abdominal and crural
structure and cannot very well be subdivided in a generic sense,
although maritimus is certainly very aberrant in its oval, sub-
connate elytra, with probable absence of hind wings.
Coleopterological Notices, VI. 68T
The genus Antliicus, as here limited, ma}- be said to comprise
those species of the tribe Anthicini which have the mesosternum
normal and undilated, the last joint of the antennae entire, the
pronotum unmodified in structure, and the vestiture simple, — that
is, consisting of a single set of hairs, disregarding in this connec-
tion the erect setfe which are especially tactile in function. The
last joint of the maxillary palpi is moderate in size and securi-
form, and the antenntB are comparativel}' short and gradually
enlarged toward apex, — never capitate as in Sapintus. It is very
abundant in species throughout the United States, but, in com-
7non with all other heteromeride groups, is particularly well rep-
resented in the southwestern parts of the country and in the
regions bordering the Pacific Ocean.

In this genus, as in all other large genera containing numerous
species'which are abundant as a rule in individuals and widely
diflused, there are certain pronouncedly distinct typical forms
surrounded b^^ others, evidently closel3^ related, and derived from
a common progenitor in comparatively recent times. It is not,
however, for the systematist at the present time to pronounce
any definite opinion concerning the status of these more closely
allied species; he can only record them in order that they may be
referred to by future investigators, provided with more ample
data. Only those forms are here described under separate names
which differ structural!}^ to a definite and obvious degree, and
their true relationships will be a problem to be solved mainly by a
study of life habits and interbreeding, if such subtle matters can
ever be looked into.

This is also a very distinct species, represented at present by
the unique type in the LeConte cabinet at Cambridge, Mass. It
also has the body clothed sparsely with long erect hairs, which
are one-third as long as the width of the prothorax, but the head
is truncate, quadrate, closely and not very coarsely punctate,
with a narrow impunctate line ; eyes large ; antenna^ thick, a little
longer than the head and prothorax. Prothorax convex, the
sides oblique, not sinuate, a little narrower than the head and as
long as wide, the punctures fine but deep, even, rather close but
distinctly separated. Elytra twice as long as wide, not quite
twice as wide as the prothorax, the punctures strong but not re-

California, from Sonoma to the southern parts of the State.
The male sexual characters are feeble, the fifth segment being en-
tirelj' unmodified on the disk and rounded at apex, the genital
segment feebly sinuato-truncate throughout its width. The cor-
neous sheath of the copulatory apparatus is quite simple, reduced
to a flattened fillet, feebly excavated along its under surface,
gradually and evenly- narrowed from base to apex, the latter ob-
tusely rounded and blunt, not at all enlarged or modified ; viewed
in profile, however, this corneous organ is seen to depart some-
what from the usual form in curvature, for, instead of being bent
downward, it is feebly bent upward toward apex, the entire organ
being protruded vertically downward in normal fashion from the
abdominal apex ; it is only about one-fourth as long as the abdo-
men.
4. A. hecate n. sp. — Moderately stout and convex, polished, black
throughout, the legs and antennte pale flavo- testaceous; elytra each with a

This species is closel}' allied to crihratus, differing in its less
sparse, shorter, less erect and bristling pubescence, more narrowly
rounded and prominent humeri which are more transverse at base^
and in coloration. The latter is evidentl}" a development of the
pattern seen in cribratus, but is ver^^ constant in the four speci-

The general description of LaFertc', more especially the phrase
"tetedistinctement ponctuee," and the dimensions — 3.0 by 1.0 mm.
— leave scarcely a doul)t that the true ephippium of that author
is the species named difficilis hy LeConte; and the form described
subsequentl}- under the name confasus is identical in every way.
the two large series in the LeConte cabinet agreeing completely,
even to the specimens which bear the type-labels.
This species occurs throughout North America east of the
Rocky Mountains, from New York to Texas (El Paso). Some
specimens from Wyoming are feebly marked like the Californiau
pinguescens, but they may be readily distinguished from that
species by the sparser punctuation and rounded temporal angles.
The corneous copulatory sheath is elongate, ])arallel-sided,
transversely and strongly convex toward base, flattened toward
apex, where it is rather abruptly narrowed in the form of a perfect
ogive, the apex of the ogive produced slightly in a small promi-
nent point; the lateral edges of the flattened portion toward apex
are broadly reflexed. In profile the organ is straight ; the mem-
branous eflferent duct beneath is large and subcylindrical.

Closely allied in general characters and coloration to ephip-
pium, but distinguishable very readily b^- the much smaller eyes.
The copulatory sheath is similar in form to that of r.phippium
but is more gradually and acutely ogival, the apex of the ogive
produced in a finer point ; on the upper surface at apex the sides
are very much more narrowly :nid feebly reflexed than in ephij:)-
pium.

California (Yuma) and Arizona (East Bridge). This form is
smaller, narrower and paler than any of the others of the ephip-
piuni group, and the elytral punctures are more uniform in size
throughout the disk; the pubescence, also, is decidedly shorter

in regard especially to the form of the prothorax, which does not
differ from his difiicili.^ to any noticeal)le degree.
8. A. piiisiiescens n. sp. — Rather stout, convex, shining, dark piceous,
the under side black; elytra pale brownish-llavate, very feebly and indefinitely
clouded with piceous in an oblique spot at the middle of each ; legs and an-
tennai pale; pubescence coarse, semi-erect, cinereous, not dense but consi)ic-
uous. Head quadrate, as long as wide, feebly convex, coarsely, deeply,
moderately closely punctate, with an almost entire median impunctate line;
eyes large, prominent, the tempora straight and parallel, with the flanks flat-
tened behind the eyes, about two-thirds as long as the latter; base broa<l]y
arcuate, not at all impressed, the basal angles very distinct and rather narrowly
rounded; antenn;c somewhat slender, feebly incrassate, not quite as long as the

parallel and feebly arcuate, a little more convergent l)ehin(l the middle, the
apex somewhat broadly rounded; humeri widely and transvensely exposed at
base; omojjlates very feeble; punctures rather coarse, sej)arated by scarcely
more than their own widths. Abdoweri polished, finely Init not densely punc-
tate, the legs long and rather stout. Length :].-3 mm. ; width 1.1."> mm.
California (8an Francisco to Los Angeles).
The male has the posterior tibiae broadly, feebly swollen witliin
in basal two-thirds, the fifth ventral unmodified, rounded behind,
the genital segment arcuate at tip in the middle and thence sinuate
for a short distance to each lateral angle. The copulatory sheath
is parallel-sided, as in the preceding species, but the tip is much
more abruptly and briefly ogival, the apex of the ogive pro-
duced in a broader, obtusely rounded process, the flattened
superior surface at apex only ver^^ slightly and narrowly im-
pressed along the obliquely rounding sides of the ogive. Six
specimens.
The four preceding species are mutually closely allied, and evi-
dently descended from a common stock in comparatively recent
times. Whether they should be termed species or geographical
varieties is, at the present time, a matter of opinion ; they all
differ by well marked peculiarities of structural detail, and, in the
opinion of the writer, can be considered geographical varieties
only in the sense that all the species of a genus are geograpliical

or environmental varieties of a common parent species. Tliese
four species, and probably a few others yet to be described, con-
stitute a subgenus or a small and pure genus within a large and
complex so-called genus, as shown by the common type of sex-
ual organization. Primary sexual characters are, as far as known,
exceedingly constant and permanent features, and decided ditter-
ences in them should apparently indicate divergence at compara-
tively' remote epochs. In fact, as before indicated, these sexual
characters when ditTering decidedly in type are extremeh^ impor-
tant taxonomic elements, and are often indices of generic iden-
tity. This is not to say that all such genera should necessarih'
receive distinct appellations at present, nor does it mean that
these are the only criteria for the estimation of genera, as wo fre-
quently meet with entire families, which must be split up into
genera because of certain more or less apparently important mor-
phological inconsistencies, in which the sexual structure is quite
uniform; but it means that those groups in which the sexual
structure is varied are, as a rule, the oldest and most permanently
established aggregates, in spite of any accidental similarities in
outward form or habitus.

Represented by a single female, having a large nubilate paler
spot on each elytron at about ai)ieal third. The species is distin-

A male, taken in southern California by Mr. Dunn, is placed
with this species for the present, although it (lifters in having a
relatively larger, more elongate and less medialh' rounded pro-

ation, being pale, with the head black. This specimen is the only
one befoi'e me of the biguttulus gi'oup which has the male organs
in auy way protruded, and even here they are only partially visi-
ble; the copulatory sheath has the sides straight and gradually
convergent at apex, the immediate tip of the latter prolonged in
a narrow acute point ; the excavation of the under surface con-
tinues to the extreme acute apex, becoming canaliculate along the
produced spiculiform portion ; the portion visible is perfectly
straight in profile.

The male has the fifth ventral but slightly longer than the fourtl;.
unmodified and very broadly rounded behind, the genital segment
coriaceous, large and wide, broadly arcuate throughout at apex
and with a small rounded indentation at the middle of the disk.
Two of the specimens depart noticeably from the usual form
and represent, either aberrations, or structural varieties. The first

normal form also occurred — has the punctures throughout much
coarser and sparser and the prothorax smaller, shorter, more
broadly rounded at the sides, and widest only a little before the
middle ; the second, a unique taken in Sonoma Co., has the punc-

The posterior trochanters are fiiiel}' spieulate posteriorly in the
male, and this very distinct species is, for this reason alone, as-
sociated with higuttulus ; that it realh' has but little affinity, is
however shown by the male sexual characters, wiiich are wholly
different.
The fifth ventral is broadly rounded, but slighth^ longer than
the fourth, and unmodified, the genital segment corneous, feebl}^
and rather broadly arcuato-truncate at apex, with its surface
transversely impressed posteriorly. Only the apical part of the
copulatory sheath is visible, but this is modified so as to no longer
serve as a protective sheath, but simpl}^ as an anchor ; it consists
of a slender parallel-sided shaft, having at the apex a perfect and
strongly developed double barbed cordiform enlargement, the
lateral lobes of which are obliquely prominent posteriorly ; viewed
in profile the barbed point is arcuate downward, with its ex-
treme tip acute.

This species is closely allied to higuttulas, but has the elytra
longer, more obliquel}- and rectilinearly narrowed toward apex,
the pronotal punctures rather coarser and less dense, those of the
elytra somewhat stronger and relatively more obvious toward
tip, the abdomen duller and more densely punctate, the prothorax
of slightly different shape, and differs also in several other details

Arizona CBenson). Mr. G. W. Dunn.
The single female represents a species allied rather closely to
biguttulus, but departing structurally in its stouter thicker body,
and much coarser and sparser punctuation of the head and pro-
notum.
There is before me another female, taken b}' Mr. Dunn at El
Paso, Texas, which I refer for the present to this species,
although it differs to a great degree in color; it is black through-
out, the legs paler, the pronotum paler in basal half, the elytra
testaceous, with the basal margin, a large uneven median and
smaller subapical fascia, black, the last two enclosing the usual
pale spot, which is not at all suggested in the type of solidus;
the prothorax, also, is noticeably shorter, being not longer than
wide.

Utah (southwestern). Mr. Weidt.
The single female represents a form closely related to biguttulus,
but ditfering in the characters heretofore stated. It is possible
that the elytra ma^- haA'e been accidentally denuded in this speci-
men, but it is difficult to imagine how this could have been ef-
fected so uniformly, not a single'long hair remaining, except the
usual series af erect tactile setie along the flanks toward base.

Oregon (The Dalles). Mr. Wickham.
This species is remarkable, among its associates of the present
group, in the form and small size of the prothorax, the constric-
tion being at a greater distance from the base than usual ; it re-
sembles cephalotes, but differs greatly in its smaller head and pro-
thorax ; in decrepitus the basal width of the latter is almost
equal to its maximum width. The sex of the single specimen in
my cabinet has not been determined.

California (Mendocino, Humboldt, Lake and Sonoma Cos.).
It is possible that there nia^- be some closely allied species in-
termingled in the large series before me, but they cannot be ad-
vantageously separated at present. This species is closely allied
io punctidatui< and is similar in the male sexual characters, but it
is somewhat more slender, with less elongate elytra, more finely
and much more densely punctate head and prothorax, the latter
relatively' narrower, and is never black, while of the numerous
specimens of punctulatus which I have taken, none are pale and
the two forms are never found in the same locality.
The el3'tra are impressed along the sutural margin toward apex,
esiDecially in the male.
A single female from Tahichipi Pass is associated with mer-
curialis for the present, but it almost certainly represents a dis-
tinct and decidedly stouter species.

The copnlatory sheath is long, moderately stout, only feebly
arcuate from base to apex, parallel-sided and transversel}^ convex
from a dorsal point of view, gradually narrowed in a long simple
ogival and not very acute point in apical third, the under surface
deeply excavated throughout, the walls projecting strongly in-
ward at basal fifth or sixth. It is thus of the same type as in
punctulatus, but is parallel, more pointed and much less arcuate.

what closely punctate, without a well-defined smooth line, the base truncate
and feebly impressed; eyes large and prominent, at a little less than their own
length from the base; antennaj long and rather stout, decidedly incrassiite, as
long as the head and prothorax, the tenth joint not quite as long as wide.

This species is closel}^ allied to cert'^nMS, differing in its stouter
and more incrassate antennae, broader head which is broadly im-
pressed in the middle at base, and in its still larger eyes. The
copulatory sheath is nearly similar to that of cervinus, but is
more gradually narrowed to an obtuse ogival point in more than
apical half; the efferent duct is stout, but becomes rapidly and
obliquely pointed toward apex.

These quadrimaculate species form quite a distinct and natural
group by themselves, and have the four elytral spots remarkably
constant in form and size through long series. These spots are
evidently due to protective mimicry, possibly of some species of
Bembidion, and have therefore been gradually evolved by natural
selection ; their constancy is easil}^ accounted for in this wa}'.

The six specimens in my cabinet show more tendency to vary
in color than in vulneratus, in one example the basal pale area
spreading feebly along the suture posteriorly, and the pronotum
var3'ing from intense black to pale testaceous; the male sexual char-
acters and smaller eyes will distinguish it at once from vulneratus,
which is the only species which is at all similar.

The elytra have each a very large pale spot, extending from
near the extreme base to the middle, wliere it is united with an-
other large elongate-oval spot extending to apical eighth. The
single specimen is a female, separable at once from Junctus by
the large eyes, and readily distinguishable from vulneratus, which
it more closely resembles, by the relatively smaller prothorax,
much denser punctuation throughout, and rather shorter and
broader elytra, in addition to the distinct ornamentation.

feeble, the fifth ventral unmodified, the genital segment short,
broad, pale and coriaceous, flat and broadly, feebh'^ truncate at

I took a single pair at the locality indicated ten 3'ears ago, and
place with these examples a specimen subsequently received from
Los Angeles Co., which agrees apparently in every particular,

are very simple, the fifth ventral being unmodified, the genital
segment trapezoidal, feebly convex and polished, with the apex
feeblv arcuato-truncate and fringed with rather long, stiflT and
porrect cilia.
Obliquus differs from both nanus and peninsularis in its larger

its much longer, wider and less convex elytra, with the humeri
more broadly- and transversely exposed at base.

broadly, feebly arcuato-truncate at base, the angles distinctly rounded; eyes
rather large and convex, decidedly longer and more prominent than the tem-

At each side of the front, near the point of antennal insertion,
there is a small pale impunctate spot of doubtful significance, but
possibl}^ a point where the condyle of the basal joint thins out

The large series in my cabinet shows that this is a species dif-
fering from na7ius in its larger size, much denser sculpture and
deeper color, and, from inscitus, in its smaller eyes, longer and
parallel tempora, denser cephalic pnnctures and less convex
elytra. I have before me a single specimen from Alameda Co.,
which is much stouter than any of those from the above localitx-^
(2.4 by 0.85 mm.), with dense abdominal punctures, and a cloud
on each elytron not extending to the sutui'e ; it probabl}" repre-

California (San Jose and San Francisco) and Oregon (The Dul-
les). This is a very small and rather remarkable species, which is
probably more nearly related to cei'vinus than to those with which
it is here associated. The fifth ventral of the male is unmodified ;
the genital segment is large, coriaceous, very broadly arcuate
throughout its width, not impressed ; the copulatory sheath
seems to terminate in a slender parallel-sided shaft which is
abruptly and transversely enlarged at tip but scarcely barbed.

Tliis small and inconspicuous species is sufficiently differen-
tiated from the preceding by its short elytra, small and more
rounded prothorax, and other characters as heretofore stated. I
have placed with the California type, taken b}' Mr. Wickham, two
pale specimens, one with nubilate elytra taken in the southern
part of the State b}- Mr. Dunn, also a specimen taken at Poca-
tello, Idaho, by Mr. Wickham, which has the pubescence still
longer and more shaggy, and finally a larger blackish specimen
from New Mexico.
The species in this particular part of the series are so closely
allied and apparently so indefinite, that I can only select at pres-
ent a few of the more obviously distinct ones for description as
landmarks ; much more extensive material will be required to
enable the future reviewer to fully differentiate them.
55. A. iiilliidlis n. sp. — Moderately narrow and convex, shining, rufo-

somewhat wider than long, minutely and not densely punctured, with a nar-
row impunctate line, broadly arcuate at base ; eyes moderate in size but promi-

The type is quite distinct in coloration, the oval oblique pale

There is another Florida example before me, agreeing nearly
with ictericus, but having the eyes larger and less convex, the

California (San Diego). One of the most aberrant species of
Anthicus, because of the perfectly oval elytra without trace of
humeral angles ; it is quite local in habitat.
This is possibl}- the species erroneousl}- identified b}' Dr. Horn
in his recent catalogue of the Coleoptera of Lower California
(Proc. Cal. Acad. Sci., 2, lY, p. 355), as ictericus Laf., the mari-
timus Lee. of Horn probably being any one. of the larger species
with triangular head, here referred to the genus Ambl^'derus of
LaFerte. These last bear onlj- a feeble superficial resemblance
to the true maritimus, and cannot be associated with it systemati-
calh'. It is almost needless to add that there is no resemblance
whatever between maritimus and ictericus, which latter does not
occur near the Pacific coast, and the same remark applies to A.
sturmi Laf. (elegans), which, as far as known, inhabits the austral
regions of the Alleghany Mountains only. The Notoxus monodon,
of Dr. Horn's list, is constrictus Csy.*
Notes.
Anthicus lecontei Chmp., from the Pacific coast of Guatemala,
is said by the author to occur also in Arizona, but I have not
been able to recognize it. From the description and figure it
would seem to be most nearlj' allied to stellatus and saucius, from
the northern parts of the United States.
A. squamosus Laf., is said by Mr. Champion to be a Mexican
species, and, as the type of A. luguln'is came from the same source
and cannot be identified among our species, it seems best to re-
*It may be stated further that the Trichoharix trhwtata Say, of this list (1. c,
p. 358), is either compacta or mucorcu — species wliich are Avidely different from

Coleopterological Notices, VI. 731
gard it also as Mexican ; these two species might therefore be
appropriately stricken from our lists.
A. impressijyennis Laf., is evidently not an Anthicus, but will
constitute a genus perhaps allied to that including the Mexican
dr-omedarius, but the comparatively simple prothorax, impressed
inflated elytra and glabrous integuments form a singular combina-
tion, which prevents us from assigning it an}' deiinite position.
A. exilis Laf., is another very peculiar species, which cannot be
retained in Anthicus, and Avhich is likewise undeterminable in its
aflSnities.
A. jMllidus Say, remains unknown.
A. jjolitus Say, is more probabl}' a xylophilide than an Anthi-
cus, but is completely indeterminate and may be a Tachys or
some chrysomelide.
A. csesiosignatas Boh., is said to be from " Puna "Island, Cal.,
and difters completel,y in type from an^^thing known in the United
States. Puna Island is off the coast of Ecuador, and it would
be perfectly safe to omit this species from our catalogues in the
future.
A. troglodytes Boh., likewise differs altogether in tj'pe from any
known North American species and should be omitted ; it is said
to occur at San Francisco and in " Taiti."
A. amplicollis Boh., said to occur at San Francisco, differs com-
pletel}^ in type, as in the two preceding cases, and is evidently
not North American ; it should also be omitted.
A. nitidas Boh., seems to be allied to nitididus Lee, but can-
not l)e identified with any of our species, than which it is much
smaller (1. 'i^ mm.; w. f mm.); San Francisco. A. atomarius
Boh., does not appear to differ from nifidus ( 1. 2.0 mm.; w. f mm.);
San Francisco. As these two species have a North American
habitus, they might be retained in the lists until their identity can
be determined.
Mr. Champion very kindly sent me, some 3'ears ago, a number
of typical representatives of species described or quoted by him
in the Biologia Centrali-Americana, and upon these it seems de-
sirable to remark as follows : —

oped.
A. exiguus Chmp., seems to lie bet^veen the nanus and ictcrieus gi'oups of
true Anthicus, but is altogether distinct from any of our numerous small
species.
A. dromcdnr'ms Laf., -will form the type of a distinct and still unnamed
genus, allied to Malporus, but with a far greater extension of the mesosternura
and complete absence of long erect tactile setaj.
A. spinicMis Laf., is also the type of a distinct genus, named Acanthinus
by LaFerti!' (Mon., p. 136), and characterized by a great lateral extension of
the mesosternum and subseriate elytral punctures; the genus extends into
southern Texas.
SAPIXTUS n. gen.
While it is true that the species separated from Anthicus un-
der this name appear to possess no very radical structural modi-
fication, there are so many minor points of divergence, and the
species are so evidently homogeneous among themselves, that I
have no doubt of the necessity for the division, especially as
these differences are accompanied by a marked peculiarity of
general habitus.
The body is stouter than in Anthicus, with relatively much
longer el3'tra and smaller prothorax ; the elytral epipleurre are
wider, the first joint of the hind tarsi is longer, and the corre-
sponding tibial spurs are shorter and much more slender, some-
times apparently almost obsolete. The vestiture is quite differ-
ent, consisting of two distinct sets of hairs, besides the erect
tactile setic, the longer and more erect hairs arising from the
coarse punctures, the shorter and generally more decumbent
pubescence from minute punctules scattered over the interspaces.
Finally, the antenniB terminate invariabl}- in an abrupt, though
feeble, three-jointed club. In fact Sapintus appears to constitute
a true genus, and can in no wise be regarded as a subgenus of
Anthicus ; it is confined geographically to the United States east
of the Rocky Mountains, extending well into Mexico, and is rep-
resented in the arid Sonoran province by one peculiar species ;
it does not occur at all in the true Pacific coast fauna.
The species can be distinguished among themselves as follows:
Eyes large and rather strongly convex, the body usually stouter.
Body T)lack or l)rownish-black.
Legs blackish.

The description is taken from the male, which has ver}^ feeble
sexual characters in striking contrast to the preceding species.
The anterior legs and trochanters are normal, the fifth ventral
much longer than the fourth, unmodified on the disk, the apex
feebly truncate and with a finely but strongly beaded edge, the
genital segment dark and subcorneous, perfectly even on the disk,
with the apex broadly and evenly truncate. The female diff"ers
from the male considerably in general form, the prothorax being
smaller, shorter and more narrowly rounded at the sides ante-
riorly, the elytra relatively much broader, more strongly arcuate at
the sides and nearly two and one-half times as wide as the pro-
thorax. The single pair represents a species allied in general
characters to pubescens.

opening on its upper surface.
4. S. COlonus 11. sp. — Rather stout autl convex, shining, the pronotum
duller, pale castaneous, the head, prothorax and antennae paler and more
rufous, the latter slightly infuscate at apex; entire under surface and legs pale

Delaware.
The single specimen before me is of undeterminable sex ; the
fifth ventral has a rounded and very shallow, sparsely punctate
median area, but the segment is short, only slightly longer than
the fourth, and there are no other essentially male characters,
although there seems to be a coriaceous genital segment visible
by glancing under the tip of the fifth. This species is allied to
fulvipes, but differs in its paler color, larger size, closer and less
coarse elytral punctuation and denser vestiture ; the elytra are a
little longer.
5. S. liispidlllus n. sp. — Stout, convex, shining, the pronotum dull, pale
rufo-testaceous throughout, the autennal club and elytral suture frequently
infuscate; pubescence rather long and erect, abundant, pale, bristling and

Texas (Austin).
The description is drawn from the female, but the niale scarcely
differs in general form, except that the elytra are less dilated
behind.
The male has the anterior and intermediate trochanters acutely
angulate and prominent posteriorly, but scarcely spinose, the
corresponding tibiae unmodified, the fifth ventral short, scarcely
visibl}' longer than the fourth, broadly rounded or subtruncate,
with a finely beaded edge at apex but unmodified on the disk,
the genital segment subcorneous, flat, smooth, transversely and
"widely truncate at apex, the edge provided with a few widely
spaced short stiff" setai, the copulatory sheath moderate in length,
flat, straight in profile, the sides subparallel or just visibly con-
vergent and straight from the base nearh' to the apex, where it
is abruptly narrowed and produced in a slender acute point ; on
the upper surface it is obtusely and strongl}' carinate along the
median line, the carina continuing along the narrowed apical
spicule to the extreme apex; the efferent duct is shorter than the
upper and penetrative organ, and both together project from a
short basal sheath in the nature of a second genital or psuedo-
segment. Four specimens,

Florida and Louisiana ( New Orleans, — LaFerte). The single
specimen in my cabinet seems to be a male, judging by the ex-
posed pygidium ; it has the anterior coxre angulate behind and
the corresponding tibiffi not bent but densely clothed with short
stitf setse within toward apex, the intermediate trochanters and
tibiae not modified, the fifth ventral long, evenly and almost semi-
circularly rounded, unmodified on the disk and about three-fourths
longer than the fourth. This form of the fifth segment is very
different from that of hisjndulus, and in fact throughout the
present genus the species, which generally resemble each other
very strongly or adhere to a common type of structure, differ
strikingly among themselves in the secondary sexual modifica-
tions of the male.
There are several points in the original description of pusiUus,
which give rise to grave doubts concerning the identity of the
present species. For example, the phrase " les yeux tres-peu
saillants," will not accord with this form, nor with any other of
the genus known to me; also "corselet retre'ci faibleraent
et progressivement depuis les pommettes, qui sont pen saillantes,
jusque'a la base, qui ne parait nullement marginee ; " finally
" el3' tres presque trois fois aussi larges que le corselet et
plus de deux fois aussi longues que larges en oval tres-allonge
posterieurement." The length and width are given as 2.0 and O.fi
mm., respectively; that is, if these measures are correct, the in-
sect is proportionally much more slender than any other of this
pai-t of the genus, and yet the elytra are nearly three times as
wide as the prothorax. Either the description is grossly inexact,
or the insect of LaFertd is a very remarkable species, quite dif-
Coleo2:tterolocjical Notices, VI. 739
ferent from any known to me.* My only reason for adhering
provisionally to the present identification, is that my single
representative is a male; in the female the prothorax is sometimes
projiortionally distinctly' smaller than in the male.

The four specimens before me vary greatly in size as is usual
in this genus, and the description is drawn from the male, this sex
having the anterior tibiae very strongl}' arcuate aijd pubescent
within, the intermediate more apically and less strongly arcuate,
the anterior trochanters feebly and obtusely prominent behind ,
the intermediate unmodified, the fifth ventral moderate in length
and evenly rounded behind, unmodified or only slightl}' flattened

This species, which is represented b}- a single male, is closel}^
a,llied to festinans, but ditters in its smaller prothorax which is
much more broadly margined at base, in its feebler and closer
elytral punctures and in the sexual characters. The anterior and
intermediate femora are distinctly arcuate toward apex, but the
trochanters are unmodified, the fifth ventral moderate in length,
rounded or feebly subtruncate at apex and unmodified on the
disk. The elytra completely lack the strong and conspicuous
subapical impressions near the suture which characterize the male
of festinans.
10. S. tiiiiidil!^ n. sp. — Slightly stout, convex, shining and rufo-testa-

finer near the suture, the short hairs extremely minute but very coarse, the
vestiture not dense and pale throughout. Head transverse, convex, not dis-
tinctly punctate, rectilinearly truncate and unimpressed at base, the angles
broadly rounded, the tempora becoming parallel just behind the eyes which
are rather small, convex and prominent, situated at much more than their
own length from the base; antennce somewhat longer than the head and pro-

but the fifth ventral has a peculiar discal excavation ; the pos-
terior edge of the segment is quite evenly rounded, but thick
and deep vertically, and the large rounded impunctate pit at the
middle of the disk thins out the vertical posterior edge into a flat

AMBLYDERIS Laf.
The American species referred to this genus apparently ditter
in no essential particular from the North African types of La-
Ferte, the tubercles along the crest of the subapical declivity of
the pronotum being however always inconspicuous. Amblyderus
is without doubt a perfectly valid genus, and will prove to be a
tolerably large one in the colder parts of the eastern United
States and in the true Pacific coast faunal region, where its mem-
bers constitute one of the most characteristic elements of the sea-
beach population.
The eight species here deemed worthy of description may be
recognized as follows : —
Species of the Pacific Coast; elougate-oval, very convex, densely clothed Avith
short coarse decumbent pubescence; tubercles and punctures of the prono-
tum indiscriminately intermingled and apparently mutuallj' indepen-
dent.
Larger species, not under 3 mm. in length.
Elytra black, rarely dark brown, the head and prothorax paler..!, olie^mis
Elytra and entire body pale Inteous-white, the integuments translucent;
elytra shorter and more attenuate near the apex 2. al1)icaiis
Smaller species, always distinctly less than 3 mm. in length.
Stouter, the head very small, scarcely more than two-thirds as wide as
the prothorax 3. parviceps
Rather slender, the head relatively larger, about five-sixths as wide as the
prothorax 4. gracileiitiis
Species of the Great Lakes and Atlantic Coast; tubercles of the pronotum
situated each immediately before a setigerous puncture, the punctures and
tubercles evidently mutually connected.
AntenuiTe shorter, stouter and sul)nu)nilif(>rm except toward base; vestiture
rather sparse and somewliat readily removable.
Elytral punctures rather small, sparse and not very strong but al>ruptly
defined 5. graiiulai'is
Elytral punctures coarse, much closer and impressed; elytra shorter; pro-
thorax much more transverse 0. piiiictiger
Antenna- long and slender, gradually and more or less feebly stouter to-

Elytra two-tiiirds kmger than wide. Lake Sujierior 7. pallens
Elytra much shorter and more opacjue, scarcely one-half longer than
wide. Atlantic Coast 8. areiiariiis

versely trapezoidal, distinctly wider than the head, widest and more strongly
rounded near the apex, the sides thence convergent and broadly, evenly arcu-
ate to the basal margin which is distinct and cylindrical for a short distance to
the base; apex transversely and very feebly arcuate, nearly one-half wider than
the base; disk finely, closely tuberculose, also minutely punctate, abruptly
declivous and very feebly concave toward the middle anteriorly, the summit
of the declivity not more strongly tuberculose; median line slightly impressed.
Elytra sulioval, very convex, scarcely more than one-half longer than wide, a
little more than one-third wider than the prothorax, the sides subparallel,
evenly and strongly arcuate; apex somewhat narrowly subtruncate; sides

reticulate, finely but strongly, densely punctate. Legs as i,n Anthicus, mod-
erately long, thick. Length 3.1-3.8 mm.; width 1.25-1.4 mm.
California (San Francisco).
The male has the anterior tibiiv thick and strongly, inwardly
arcuate toward apex, the fifth ventral rounded behind and un-
modified, the genital segment large, corneous, black, truncate at
apex and transversely, unequalh' impressed throughout the width ;
the copulatory spicule is broad and stout, but rather abruptly
narrowed near the apex and prolonged in a slender straight pro-
cess which is very strongly compressed and vertically laminiform,
the apex slightl}' swollen vertically' and obtuse in profile.
This is one of the largest, and, with the exception of Tanar-
thrus .Halinus, probably the bulkiest s])ecies of the tribe in North
America. I have taken it in large numbers on the sandy sea-
beaches near the city.

California ( sea-beaches of Los Angeles Co.), Mr. Wickham.
The male has sexual characters of the same type as in obesus,
except that the genital segment is pale in color and more coria-
ceous ; the copulatory sheath is not protruded in any of the types.
This species is allied to obesus, but differs in its more feeble
sculpture of the head and pronotum, in its shorter and more
rounded elytra, smaller size, and very pale coloration, the integu-
ments being diaphanous. In both this and the preceding species
the elytra have each a short canaliculation along the suture near
posterior third, -which is common to both sexes. Four specimens.
A female before me seems to represent a distinct species allied
to the above ; it is entirely pale, with the sutural bead blackish
and the elytra longer, with the punctures larger, stronger and
more impressed. This specimen has a deep fovea-like impression
behind the left hind coxa, of which there is no trace on the right
side, but is not deformed in anj'^ other wa^'.
3. A. parviceps n. sp. — Moderately stout, very convex, feebly shining,
dark rufo-tcstaceous, the under parts of the hind body and the elytra in great
part suffused with blackish; pubescence moderate in length, coarse, somewhat
dense, recumbent, cinereous and distinct, without trace of erect seta-. Head
very small, triangular, al)out as long as wide, feebly convex, closely covered
with fine punctures and small tubercles, the smooth median line wide ante-
riorly, becoming narrow toward base but entire; eyes moderataly large and

line impressed toward apex. Elytra elongate-oval, two-thirds longer than
wide, two-lifths wider than the prothorax ; sides evenly arcuate; base broadly
sinuate, the apex equally broadly subtruncate; humeri narrowly exposed at
base; disk evenly convex, finely, not very closely punctate, without further
modification, except the subsutural impressions at apical third W'hich are fee-
ble. Abdomen dull, densely reticulate, finely punctate, rather sparsely and
coarsely pubescent. Legs somewhat long and not noticeably stout. Length
2.6-2.8 mm. ; width 1.0 mm.
Californifi ( southern ). Mr. H. C. Fall.
The apical declivous surface of the pronotum is distinctly and
transversely concave, but its upper crest is not more strongly
tuberculose. The male has the anterior tibi;c bent, the fifth ven-
tral feebly sinuato-truncate at apex but otherwise unmodified, the
genital segment moderate in size, pale, truncate, and transversely
and unequally impressed, the copulatory spicule with the tip ab-
ruptly'' narrowed and produced in a shoi't slender acute point,
which is subcylindrical and not noticeably compressed.
With the two males which I received from Mr. Fall, I have as-
sociated a single male from Alameda Co., which does not seem to
differ specifically.

California (near San Francisco).
The narrower form, still smaller size and relatively- larger head
will readily distinguish this species from the preceding. In the
male the anterior tibiit are bent toward apex, the fifth ventral
feebly sinuato-truncate at apex but not otherwise modified, the
genital segment thin, broad, truncate at apex, strongly and trans-
versely impressed, the surface bent downward toward apex
throughout ; the copulatory spicule is abruptly narrowed near the
apex and produced in a short slender process, which is gradually
bent upward and not compressed ; the efferent duct beneath the
spicule is broad, flat, transversely truncate at tip, bent first down-
wai'd then upward and projects in the t3-pe specimen far beyond
the corneous spicule.

verselj impressed. The single male, which I took immediately
behind the ocean beach, represents a species which is closely allied
to pallens, but differing in its shorter, more opaque and more
densely punctate elytra, shorter, more incrassate antennoe, less
prominent tempora, differently shaped and less transverse pro-
thorax, and in other characters.
In this species the small tubercles of the head and prothorax
show plainly their origin in simple asperities at the anterior mar-
gins of the punctures, and, in both arena7'ius and paJlens, the
declivous anterior part of the pronotum is less abruptly defined
than in the others here described.
TAJVARTHRUS Lee.
This is a singular and isolated type of the Anthicini, not very
closel}^ related to any other, but agreeing better with Anthicus
than with any of those genera which have an abnormal extension
of the mesosternum. Its divergence from Anthicus is, however,very
marked in the depressed body with subtruncate aud more or less
abbreviated elytra, in peculiarities of tarsal and palpal structure
previously noted, in the smaller and distinctly less coarsely faceted
eyes, and in the remarkable bilobed ultimate joint of the antenna,
the constriction in some species being so deep that it is almost
impossible to decide at once whether or not it really sepai-ates
the one joint into two.
The sculpture of the integuments is also worthy of remark.
The punctures of the head and pronotum are shallow and vario-
late, except in Tanarthrus proper, and, in all but one of Tanar-
thropsis, each puncture is accompanied by a small but pronounced
and shining tubercle. The surface of the elytra is covered closely
with a reticulation of fine lines, and, besides this sculpture, there
are frequentl}^ two independent sets of punctures, one very minute
and bearing the visible hairs, and the other still very small but large
by comparison, which are circular, shallow and crater-form, either
nude or bearing extremely minute setae onl}^ visible under con-
siderable amplification. Some species have, besides the reticula-
tion, only one set of minute punctules each of which bears a hair,
the singular varioles being completely wanting. This character,
in conjunction with the varjang length and apical structure of the
elytra, shape of the head, size of the eyes and structure of the

forms related to salicola.

This species is distinguishable by its very short truncate e\y-
tra, and differs from every other in having the elytral pubescence
streaming out perpendicularl}' from the suture in basal third
and inner half. The exposed part of the tergum consists of a
very large convex, finely and sparsely punctate segment, para-
bolically rounded behind and having, near the base, two trans-
verse and densely pubescent patches nearly trisecting the width,
analogous perhaps to those of the Omalini or at least similar in
origin and purpose. The single specimen is a female, kindl}' given

in this section, there are two longitudinal series of long tactile
setffi, two setae to each segment. The dusky tip of tlie el^'tra, re-

This genus contains luimerons species in North America, but
is more abundant in the temperate than in the troi)ical regions of
the continent. The thirty-two species included in the table be-
low, appear to be rigorously definable and without suspicion of
intergradation, as far as can be observed Avith the abundant ma-
terial before me. The species in fact seem to be unusually con-
stant through long series, in the majority of cases even in colora-
tion, and types of coloration have proved so stable that it is
found convenient to divide the genus into groups based primarih^
upon these characters. It seems evident, moreover, that this may
be as natural a grouping as ^ny which can be provisionally
assumed.
The thoracic hoiii is another character heretofore regarded as
especially prone to variation, which I have found to be quite con-
stant in general form and structure within the same sex of the
various species, and this is what might be anticipated from analog^'.
It is true that the horn is an unusual and greatly developed struc-
ture of scarcely' obvious utility in the economy of the animal,
if we consider the genus in relation to the other genera of An-
thicini; but, on the other hand, we must remember that within the
large genus Notoxus, the horn, wiiatever its use, whether a \)vo-
tection for the head or something more obscure, is a remarkably
characteristic generic feature, and consequentl3^ a long established
and permanent structure, and ought not to possess much specific
variabilit}' at the present time.
The species may be readily recognized as follows : —
Elytra entirely black, sometimes feebly and indefinitely paler toward the
apex 2

Elytra black, crossed by two pale fascia; 4

Crest completely obsolete, the posterior fascia large and enveloping the apices;
median fascia greatly prolonged along the suture, becoming bifurcate;
elytra without erect setae planicoriiis Laf.
The characters of planicornis, which is the only species not
before me, are taken from the figure given by LaFerte; this figure
does not, however, at all agree with the description, which states
that there is a small scutellar spot, a median sinuous fascia and
another ante-apical, which is composed of two lunules ; this would
make the markings agree nearly with those of delicatus, but as the
description states that there are no " polls raides " in planicornis,
and as these ai'e very evident in delicatus, I prefer to regard
the two species as distinct for the present. As I have before
explained (Bull. Cal. Acad. Sci., I, p. 333), delicatus is in no way
closely related to monodon or jnlatei.
I have considered pilatei and decoloratus of LaFerte as varities
of monodon for the present, as I have not been able to identify
them, but it is more than possible that they represent valid species.
The genus having been so recently reviewed by Dr. Horn (Tr.
Am. Ent. Soc.,XI, 1884, p. 165), it is only necessary at the present
time to describe the species announced as new in the above table.
X. Ibalteatiis. — Moderately stout and shining, rufo-piceous, the elytra
black with a broad and even transverse fascia at basal third, and another,
equally straight and transverse but narrower, at apical third ; basal margin
and apex also paler; vestiture very fine, short, even and only moderately close
anteriorly, coarser and denser on the elytra, where it is pale cinereous on the
pale bands, elsewhere brownish, without erect setae. Head distinctly smaller
than the prothorax, the eyes rather large, slightly longer than the tempora;
antennas distinctly longer than the head and prothorax, stout toward apex,
the tenth joint but slightly longer than wide. Prothorax slightly transverse,
subglobular, finely, closely punctate, the horn well developed, two-thirds
longer than wide, very feebly narrowed at base, not dentellate, the crest
strongly developed and surrounded by a fine elevated and non-dentellate
border. Elytra three-fourtlis wider than the prothorax, evidently less than
twice as long as wide, feebly dilated behind; disk very minutely, evenly,
moderately closely punctate; humeral Impression feeble; post-scutellar depres-
sion distinct. Under surface miniitely and closely punctate, the legs moder-
ately slender, testaceous. Length 110 mm. ; width 1.0 mm.

A single female specimen representing a species which is allied
to bifasciatus, but differing in coloration and several structural
charactei's. The configuration of the anterior pale fascia in
bifasciatus is perfectly constant throughout my series.
I¥. moil tail lis. — Stout, rather sliininf^, testaceous, the ahdomen darker;
eh'tra dark piceous-hrown, ^vith a broad oven and parallel-sided transverse fas-
cia of paler tint at basal third, and another, narrower, at apical third, the
latter bent forward toward the suture; base and apex also paler; vestiture
short, not very dense, somewhat coarse on the prothorax, intermingled with
sparse erect sette on the elytra. Head much smaller tban the prothorax, pol-
ished; eyes small, barely as lonu; as the tempora; antennaj two-fifths as long
as the body, moderately incrassate, the tenth joint one-half longer than wide.
Prothorax slightly wider than long, the sides oblique to the bjise behind the
middle; surface finely, densely and rather rugosely punctate; horn well de-
veloped, about one-third longer than wide, distinctly constricted at base, the
sinuation broad, the border entire, the crest well developed, with its border
strongly reflexed and entire. Elytra distinctly dilated and, at apical third,
almost twice as wide as the prothorax, scarcely more than three-fourths longer
than wide, broadly, feebh^ transversely impressed at basal third, strongly im-
pressed on the suture behind the scutellum, the humeral impression obsolete;
punctures somewhat fine but distinct, rather dense. Under surface densely
pubescent, nnnutely, densely punctate, the legs slender. Length 2.9 mm.;
width 1.0 mm.
Colorado.
This species, while allied in general appearance to some others
of this group, ma^^ be distinguished by its stout form, and, from
balteatus, by its smaller eyes, coarser punctuation and erect set;u
of the el^^tra, these being completely wanting in that species.
From bifasciatus it differs in its much longer and more distinct
erect setfe, non-interrupted elytral fasci;v, dehiscent tips of the
el3'tra, less incrassate antennfe and many other features. It is
represented before me by the female only.
IV. iilici'occi'llfii. — luither narrow, polished, dark rufo-piceous, the abdo-
men black; elytra black, with a straight transverse and entire fascia just be-

flexed obliciuely forward, liecoming feeble, to the suture; base slightly, the
apex not appreciably, pale. Head but slightly smaller than the prothorax,
polished, the eyes well developed; antennie long, slender, scarcely at all in-
crassate, more than one-half as long as the body, dark rufo-testaceous through-
out, the tenth joint about one-half longer than wide on the comjiressed side

slightly longer than wide, not constricted, evenly rounded at tip, botli horn
and crest surrounded by an acutely elevated and non-dentellate margin.
Elytra elongate, twice as long as wide, very appreciably dilated at apical third
and twice as wide as the prothorax, gradually narrowed and somewhat acutely

Arizona (near the Canon of the Colorado).
This is a well marked species, to be readily known by its long,
polished, sparsely and minntely punctate elj^tra, which are nar-
rowed obliquely behind from slightly before apical third, also by
its small prothorax with an unusually small corneous process,
long antenna and other characters.
A single specimen, probably male, was recently taken by Dr.
T. Mitchell Prudden, of New York, and kindly presented to me
together with a number of other interesting species.
]V. spatulifer, — Somewhat narrow, parallel, polished throughout, pi-
ceous-brown, the antennje paler and the elytra black, the latter with the
basal margin and a transverse fascia at basal third pale, the latter clothed
with coarser, closer and more cinereous pubescence, a transverse band occupy-
ing apical fourth also similarly pubescent, the vestiture elsewhere fine, dark
in color and very sparse; erect seta; sparse, more distinct in the cinereous
areas. Head but slightly smaller than the prothorax, convex, polished, very
remotel}' pubescent, the eyes small, much shorter than the tempora; antenna?
one-half as long as the body, somewhat thick, just visibly and verj' gradually
incrassate, slightly infuscate toward apex, the tenth joint distinctly elongate.
Prothorax globular, not wider than long, polished, finely and sparsely punc-
tate throughout, the basal tomentose line scarcely at all interrupted; horn
well developed, circularly' rounded at apex, not dentellate, feebly but rather
abruptly constricted at the middle and thence parallel to the base, narrower
and scarcely at all constricted in the male; crest abrupt, moderateh^ elevated,
acutely outlined along the sides but indefinitely so anteriorly; surface of the
horn concave and strongly scul])tured. Ehjtra t\\ice as long as wide and paral-
lel in the male, shorter and slightly inflated in the female, narrowly and ob-
liquely truncate near the suture in the former, broadly and squarely truncate
throughout the width in the latter sex, scarcely more than one-half wider
than the prothorax, rather sparsely and somewhat strongly Itut not verj'
coarsely punctate, without basal impressions of any kind, even post-scutellar.
Under surface rather coarsely and sparsely pubescent. Length 2.G-;2.8 mm.;

California (Los Angeles Co.).
A distinct species in its strongl}- marked sexual characters,
sparse and uneven pubescence, polished surface and other charac-
ters; it is allied closely, however, to denudatus, a peculiar Cali-
fornia coast species, and scarcely at all to bifasciatus, and is
placed in the vicinit}' of the latter merely to facilitate identifica-
tion. The last ventral of the male has a deep rounded median
impression. Three specimens.
X. debilitaiis. — Moderately narrow, polished, pale piceous-brown, the
elytra blackish, pale at base, obliquely more broadly toward the sides, also in
a broad anteriorlj' ai'Ciiate fascia just behind basal third, and, less markedly,
in apical fourth; vestiture sparse and rather coarse but short and subdecum-
bent, liner, sparser, more decumbent and inconspicuous in the black fascia and
at base, ifeof/ distinctly narrower than the prothorax; eyes somewhat small;
antennae moderately stout, rather short, sciircely lonp;er than the head and pi'O-
thorax, the tenth joint but slightly longer than wide. Proihornx subglobular,
slightly wider than long, minutely, remotelj' punctate throughout, the horn
nearly as in spatulifcr, — well developed, non-dentellate, broadly and feebly
constricted toward base, — but with the concave apicjil part much more pointed
and less broadly rounded. Elytra distinctly less than twice as long as wide,
about two-thirds wider than the prothorax, the sides parallel, feebly arcuate
behind, the apex broadly subtruncate and arcuate in the female, the outer an-
gles broadly rounded; disk without imjjressions, coarsely, sparsely punctate,
the erect sctic long but very sparse. Atxlomen rather sparsely, coarselj' pubes-
cent. Leng-th 2.5-2.7 mm.; width 0.8 mm.
California (San Diego).
Of this interesting species I obtained four specimens, which
are unfortunately all females ; the male, however, without doubt
has the short oblique subdentate truncature characterizing the
allied forms. It forms, with spatulifer and deuudafiis, a ver^-
distinct group of small polished and sparsely punctate species,
and differs from the first in the shorter elytra, less transversely
truncate in the female, in the coarser and still sparser punctures
of the elytra, more ])ointed apex of the pronotal process, shorter
antennae and paler coloration, and, from denudatus, in its stouter
build, different ])attern of elytral ornamentation, less coarse and
sparse elytral punctures and closer, more decumbent pubescence.
In denudatus the form of the body is very slender, the elytral
punctures remarkably coarse and sparse, the vestiture of the
elytra coarse, rather long, very sparse and not closel}' decumbent,
the antenn;\i long, slender, gradually and distinctl3' incrassate,
with the tenth joint much longer than wide, and the elytra full^'

twice as long as wide, devoid of impression and colored as stated
in the table ; the fifth ventral of the male is excessively feebly or
not at all impressed. In all three of these species the punctnres
of the el^'tra become ver}^ fine, remote and feeble toward apex.
IV. lustrelllis. — Some-what stout, shining, pale piceo-testaceous, the
elytra with a blackish transverse fascia scarcely before apical third and broadly
interrupted at the suture, without other maculation. Head just visibly nar-
rower than the prothorax, orbicular, polished, the eyes large, convex and
prominent, fully as long as the tenipora; antennaj slender. Prothorax dis-
tinctly wider than long, broadly rounded at the sides anteriorly, feebly and
obliquely narrowed and sinuate thence to the base, polished, extremely mi-
nutely, sparsely punctulate, sparsely and coarsely pubescent, the basal tomen-
tose line subinterrupted in tbe middle; horn long and moderately dilated,
coarsel}' and deeply crenate throughout, the crest strongly elevated, very long
and narrow, the margins distinct and crenulate, acute and feebly defined at
apex. Elytra not quite twice as long as wide, parallel, nearly twice as wide
as the prothorax, the sides becoming rather abruptly oblique and arcuate in
apical fourth to the oblique apical truncature; intra-humeral impression
somewhat distinct, the scutellar obsolete; disk sparsely and rather coarsely
punctate, the pubescence sparse, coarse, cinereous and decuml)ent, almost
evenly distributed, the erect setce indistinct. Under surface coarsely pubes-
cent. Length 2.9 mm.; width 1.05 mm.
California (San Francisco).
The single male represents a species allied to conformis, but
differing in its shorter and broader elytra, more dilated thoracic
process, strongl3^ dentellate at the margins and with much more
elongate crest, and other characters. There is a small feeble su-
tnral spot on each elytron just in advance of the sutural break in
the transverse fascia, but no trace of scutellar spot.
IV. iievadensis. — Moderately stout, parallel, convex, shining, piceous-
brown, with a large nubilate transvei'se fascia, interrupted at the suture, at
apical fourth. Head much narrower than the prothorax, polished but rather
distinctly pubescent and with conspicuously long sparse setae, eyes very small,
not much more than one-lialf as hmg as the tempora; antennte moderately
stout, feebly incrassate, about two-fifths as long as the body. Prothorax some-
what large, subglobular, slightly Avider than long, sparsely, very minutely
punctate and polished, the pubescence rather long but not very dense, decum-
bent; basal line diminishing greatly in width toward the middle but scarcely
interrupted; horn well developed, parallel, not constricted at base, one-half
longer than wide, rounded at apex, with the edges moderately coarsely,
unevenly and rather feebly crenulate, the crest somewhat pronounced but
short and wide, .scarcely one-lialf as long as the horn, definitely limited at
the sides but not at apex. Elytra elongate, twice as long as wide, barely two-

coarsely, sparsely punctate, finely toward apex, the pubescence rather long,
coarse, sparse, cinereous, subdecunibent and evenly distributed, the erect setie
long, coarse, rather numerous and conspicuous. Under surface and legs
minutely, closely punctulate, the abdomen coarsely pubescent. I.,ength 3.0

Nevada (Elko). Mr. Wicklmm.
Three males before me agree very w^ell among themselves and
have the tips of the elytra obliquely truncate near the suture,
and the fifth segment scarcely visibly and transversely impressed
near the apex, but the fourth specimen, also a male, differs in
form and color, having the elytra larger and longer, almost en-
tirely' blackish, and the thoracic process more strongly crenulate.
I think, however, that it can only represent a varietal modifica-
tion ; it is labeled " Nevada," without more precise indication of
locality.
N. tilliilboldti. — Stout, somewhat shining, pale, ochreo-test<iceous
throughout, the abdomen just visibly infuscate posteriorly; elytra with two
subconfluent scutellar spots, which are prolonged obliquely outward to the
lateral edges, and a broad transverse fascia somewhat behind apical third, pro-
longed broadly along the suture, abruptly ending just behind basal third, of
black; apical regions not maculate. Head much narrower than the prothorax,
finely, densely punctate and pubescent; eyes large, much longer than the tem-
pora; anteuniv rather short and stout, the tenth joint but little longer than
wide. Prothorax transversely oval, finely and somewhat sjiarsely punctate,
the coarse yellowish decumbent pubescence abundant; horn strongly developed,
spatuliform, gradually and strongly narrowed to base and margined throughout
with large prominent and distant, obtusely rounded teeth, the crest very long
and narrow, defined at the sides only by a series of elongate elevations, not
defined at the acute apex. Elytra distinctly less than twice as long as wide,
not quite twice as wide as the prothorax, not dilated behind, the sides parallel
and nearly straight, o])li(|uely narrowed and then obtusely rounded in apical
third or fourth; humeral imiiression at base narrow and well marked, the
scutellar also slightly visible; disk strongly but not very coarsely, rather
closely punctiite and shining, the decumbent pubescence coarse but only
moderately long and dense; erect setie abundant, very long, coarse and con-
spicuous throughout the upper sui'face. Length 3.6 mm.; width 1.25 mm.
California (Hoopa Val., Humboldt Co.).
The single specimen before me, probabl}- female, represents an
interesting modification of the monodon group, departing r.idically
in type of maculation near the base of the elytra, and differing
Coleopterological Notices, VI. 765
from consf.7Hcfus not only in this respect, but in the entire struc-
tural detail of the thoracic process and crest, and in the very long
bristling setffi of the elytra.
In the species of Notoxus the modifications at the thoracic apex
are quite complex, and seem designed in part to prevent a too
great lateral motion of the head, which would thus be deprived
of the protection of the thoracic process. There is, among these
modifications, a small oval subdepressed area at each side just
behind the apical margin, which has the bottom convex and very
densel}^ sculptured and pubescent ; this is especially developed in
consfTiclus, but is very small in the present species ; it is perhaps
connected in some wax with a lateral enlargement of the neck
within the prothorax.
IV. aiif^tiiiiaims. — Some-what stout, pale rufo-testaceous throughout,
the legs more ochreoiis; elytra with two feeble scutellar spots and a transverse
fascia behind the middle of blackisli, the latter rather narrow and flexed toward
the suture to the middle; lateral spots wholly obsolete. Read not perceptibly
narrower tlian the prothorax, minutely, closely punctate and pubescent, reticu-
late and dull, the eyes large, much longer than the tempora; antennai stout,
two-fifths as long as the body, gradually and distinctly incrassate, the teuth
joint obconical, much longer than wide. Prothorax small, globular, minutely
and moderatel3' closely pirnctate, polished, the vestiture fine, decumbent, not
concealing the surface, more evident along the median line; basal line very
wide laterally, broadly subintei-rupted at the middle; horn well developed,
broad, rather finely dentellate, only very slightly wider in the female, not dis-
tinctly narrowed at base, the crest strongly elevated and defined throughout
by an acute entire border. Elytra not quite twice as long as wide, at posterior
third sensibly dilated and nearly twice as wide as the prothorax, broadly,
evenly rounded behind in both sexes; disk scarcely at all impressed at base,
finely, deeply, closely punctate and dull, the vestiture somewhat coarse, de-
cumbent, cinereous, dense and evenly distributed, the erect setit abundant,
but not very coarse and decidedly short. Under surface finely, very densely
pubescent, the abdominal segments more coarsely so along the apices. Length
2.7-3.5 mm. ; width 1.0-1.25 mm.
Texas (Austin).
The male differs scarcely at all from the female. Ausiinianus
is one of the allies of monodon, and differs in its shorter, finer,
denser and more even vestiture, narrower posterior fascia, without
a subapical black cloud, much larger eyes, polished surface of the
pronotum, not concealed by the vestiture, and in other features
constituting a general facies. It is represented by a large and
homosceneous series.

N, filicoriiiisi. — Slender, convex, ratlier dull, pale Inteo-tlavate through-
out, the elytra with a feeble rounded darker spot at each side of the suture
behind the scutelluni, and a darker median spot just before apical third, the
latter with an obli(iue ramus extending anteriorly to just beyond tlie middle
gradually approaching but not touching the suture, the spot not at all ex-
tended laterally; pubescence somewhat coarse and dense, cinereous-Avhite, de-
cumbent, with distinct and rather numerous erect bristles. Head as long as
wide, dull and minutely, densely punctiito-scabrous, the eyes large, at much
more than their own length from the base; antenn:c long, fully one-half as
long as the body, very feebly incrassate toward apex, the tenth joint one-half
longer than wide, the eleventh slender, almost as hmg as the two preceding,
gradually narrowed in apical half. Prothora.c slightly narrower than the head,
somewhat longer than wide, glol)ular]y convex, polished, minutely punctate,
abundantly pubescent, the basal pubescent area rapidly narrowed and almost
obsolete toward the middle; horn subconic!il in outline, not in the least con-
stricted, the sides arcuate, tinely and rather feebly crenulate, the apex obtusely
rounded in the male, more rapidly and acutely pointed in the female, a little
broader and parallel toward base in the latter sex; crest short and wide, mod-
erately elevated, outlined by a broken series of feeble crenelures. Elytra
twice as long as wide, fully three-fourtbs wider than the prothorax, rounded
behind in both sexes, only slightly wider at posterior third than at base, rather
finely but closely and strongly punctate. Abdomen dull, the legs slender.
Length 2.7-2.8 mm. ; width 0.8-0.9 mm.
Florida (Jacksonville). Mr. Aslimeud.
The male has the fifth ventral broadly snbtruncate at apex, ex-
tremely feebly sinuate for a short distance at the middle, the sur-
face adjoining the sinuation feebl}' and transversely impressed, in
the female longer and evenly rounded, with the surface unmodi-
fied. Tiie antennje of the female do not differ appreciably-.
This species is allied to monodon, but is much narrower, with
longer and more slender antennae and quite different elytral orna-
mentation ; the spot on each el^-tron, with its oblique curving
ramus, has the exact form of an inverted comma, and differs from
any other of the monodon group in not extending at all toward
the sides of the elytra. It seems to be allied to pilatei Laf., but
is much smaller, the stated dimensions o^ pilatei being 3.6X1.0 mm.
I¥. dinocerus. — Narrow, convex, i>alf rufo-testacoous throughout, the
abdomen infuscate; elytra witli two small scutellar si)ots, a transverse fascia at
apical two-lifths jirolonged along the suture Iieyond the middle, and a dark
post-humeral marginal line, i)rolonged to the fascia or nearly to the apex, of
black. Head as wide as the prothorax, minutely, densely punctate and dull,
densely clothed with short appressed silvery pubescence; eyes large, longer
than the tenipora; anteniuc moderate, feebly incrassate. Prothorax globular,

the polished surface minutely, not densely punctate and not entirely con-
cealed by the vestiture; Itasal tomentose line wide laterally but subobsolete in
the middle; horn very broad and strongly developed, one-half as wide as the
pronotal disk in the female, slightly narrower in the male, not constricted at
base, rounded, finely dentellate, densely asperate, the crest moderately ele-
vated and defined by a somewhat broken elevated margin laterally, not de-
fined at the apex. Elytra about twice as long as wide in the male, rather
shorter in the female, slightly wider at apical third and nearly twice as wide
as the prothorax, rounded at aj)ex in both sexes; humeral impression very
feeble, the scntellar obsolete; disk finely and closely punctate but not very
dull, the pubescence dense, even, whitish and somewhat coarse; erect setaj
abundant, moderate in length. Length :2.7 mm. ; width 0.8 mm.
Texas (Galveston).
This species is also allied to monodon, differing in its smaller
size, narrower form, larger thoracic process, whiter pubescence,
larger eyes and still more minute and much denser elytral punc-
tures; the sides of the prothorax are more oblique anteriorly, the
horn being much more gradually formed than in monodon. It is
represented b^^ three specimens, in which the sexual characters
are very feeble.
jV. deserfllS. — Rather stout, slightly shining, iwle yellowish-testaceous
throughout, the elytra with a small spot at each side of the suture near the
base, and a transverse zig-zag fascia behind the middle, strongly produced an-
teriorly along the suture beyond the middle, frequently subuniting by a feeble
ray with each of the subbasal sjiots; sides behind the humeri faintly darkened.
Head subequal in width to the prothorax, densely pubescent, minutely punc-
tate, reticulate, somewhat dull, the eyes rather large, equal in length to the
tempora; antennaj slender, slightly incrassate, fully two-fifths as long as the
body. Prothorax rather small, globular, finely and sparsely ijunctate, shining
through the somewhat dense vestitiire, the basal line dilated at the sides; horn
well developed, differing somewhatuoticeably in the sexes; in the male smaller
and narrower, more acuminate, not at all constricted at base and coarsely,
deepljr dentellate, in the female larger and broader, feebly and finely dentel-
late, broadly rounded and almost entire toward apex, feebly narrowed at base;
crest abrujit, strong, limited throughout by a strongly elevated, acute and en-
tire ridge. Elytra distinctly less than twice as long as wide, twice as wide as
the prothorax, broadly rounded behind in both sexes, the sides parallel and
almost evenly arcuate throughout; humeral impression very feeble, the
seutellar wanting; disk densely, deeply and rather coarsely punctate, the de-
cumbent pubescence coarse, whitish, moderately dense, the erect setai long,
very abundant, coarse and conspicuous. Under surface densely pubescetit as
usual. Length 2.7-3.5 mm.; width 1.0-1.15 mm.

]V. constrictiis. — IModerately stout, scarcely shining, pale oclireo-testa-
ceons througliout, the head frequently, the ahdonien seldom, darker; elytra
fasciate. Head equal in width to the prothorax, narrower in the female, mi-
nutely punctiite, reticulate, densely pubescent and dull; eyes large, longer
than the tempora; antennie somewhat slender, moderate in length. Prothorax
subglohular, slightly wider than long, the sides oblique and sinuate behind;
disk rather coarsely, closely punctate, densely and coarsely pubescent; horn
well developed, similar in the sexes, somewhat coarsely and deeply crenulate,
broadly rounded and entire for a short distance at apex, Avidely dilated,
strongly constricted at base, the crest broad, abruptly elevated, broadly rounded
at apex and strongly delined throughout the sides and apex by an elevated
black and entire ridge. Elytra a little less than twice as long as wide, dis-
tinctly dilated at apical third and three-fourths wider than the prothorax,
evenly rounded at apex, a little more broadly so in the male, the humeral im-
pression very feeble; disk densely and rather coarselj^ punctate, densely
clothed with coarse yellowish pubescence, the erect seta' somewh;it long, coarse,
numerous and conspicuovis. Under surface densely and rather coarsely ])ubes-
cent. Length 2.5-11") mm. ; width 0.95-1.2 mm.
California (coast regions).
The sexual differences at the posterior extremity' of the bod}^
are almost completely undeveloped, and exist only in the slightly
more truncate elytra of the male. This species, which is repre-
sented by a large series, has been heretofore almost universally
confounded with the eastern monodoi), which it strikingly resem-
bles in facies. It is however widely and constantl}"^ distinct in
the form of the thoracic process, as ma}' be seen at a glance if
the separated series be even casual!}' examined. The elytral mac.
Illation is nearly as in vionodon, except that the subapical black
cloud on each elytron, which is almost constantly present in that
species, is here quite as constantly absent. In the vicinit}' of
San Diego there is, however, a variety of consfrictus which has
the lateral and subapical dark patches frequentl}' visible, and the
thoracic punctures a little finer and sparser, agreeing rigorously
with the northern forms in the structure of the thoracic process,
except possibly that it is a little more pointed as a rule.
I¥. ro1)llstll!Si. — Very stout, dull from the density of the vestiture, pale
ochreo-testaceous throughout, each elytron with a large rounded scutellar sjiot
and a transverse fascia at apical third, abruptly interrupted very near the
suture, but prolonged narrowly along the latter slightly beyond the middle.
Head very much smaller than the ])n)thorax, finely, closely punctate but shin-

California (Lake and Los Angeles Cos.).
This is the largest and stoutest species of the genus within our
boundaries, and is somewhat similar in facies to some of the rel-
atives of monodon, but is very distinct by reason of the truncate
tips of the elytra in the male. The male type described above is
from Lake Co., but the female before me from Los Angeles is
similar throughout, except that the thoracic process is broadly
dilated, rounded, and strongly constricted at base, and the elytra
have, at each side just behind the humeri, an inwardly and pos-
teriorly oblique dash of black. The male has the fifth ventral
truncate at tip, with its surface broadly flattened near the trunca-
ture.
From serratus, to which it is allied more closely than any
other described species, i^obusfus may be distinguished at a glance
by its larger size and stouter form, more strongly constricted
thoracic process of the female, longer and narrower crest, and in
peculiarities of el^'tral ornamentation. In serratus the thoracic
crest is very short.
N. alainedae. — Stout, convex, rather shining, testaceous, the head
darker, the elytra with a subsutural spot on each at basal fifth, and a trans-
verse, very uneven and widely interrupted fascia at apical third, which is
obliquely, more or less incompletely and indistinctly prolonged to the suture
just before the middle, of black. Head scarcely in the male, very distinctly
in the female, narrower than the prothorax, finely pubescent, the eyes moder-
ate, prominent, not quite as long as the tempora; antenn;e long, slender,
gradually and distinctly incrassate, fully two-fifths as long as the body. Pro-
thorax distinctly transverse and oval in both sexes, finely, not very closely
punctate, coarsely pubescent, the to:nento3e line almost equal in width

female, somewhat oval and convex, the sides parallel and feebly, equally
arcuate, obtusely rounded behind, narrowly and obliquely truncate in the
male; humeral impression feeble; punctures not coarse but strong, moderately

California (Alameda Co.).
The peculiar oval convex form of the elytra, and departure
from the usual t^'pe of ornamentation w'ill readil}' distinguish this
species from serratus and robustus, to which it is somewhat re-
lated. It is smaller than serratus^ with a much longer, narrower
and more ill-defined thoracic crest and shorter, more oval and
convex elytra. The female is much stouter than the male. It is
represented by three si)eciraens.
IV. pictiijii. — Narrow, elongate and parallel, rather dull, piceo-tcstaceous.
black beneath, the legs and antennsc pale; elytra with the markings piceous
the large scutellar spot frequently obsolete, the anterior fascia occasionally
disintegrated into two large sublateral spots and an elongate and more pos-
terior sutural area, the latter always joining the transverse post-median fascia;
apices always i)ale. Ihad small, much smaller than the prothorax, the pol-
ished surface not much concealed by the moderately dense vestiture; eyes
moderate, about as long as the tempora; antenuii; long and slender, about two-
fifths as long as the body. Prothorax transversely oval, finely, not very densely
punctate, polished, coarsely, somewhat sparsely pubescent, the tomentose line
very widely and completely interrupted; horn long, narrow, not distinctly
dentellate, parallel, rounded at apex, not at all constricted, the surface deeply
concave and coarsely reticulate, the crest abrupt, elevated, very short, rotuuled
at apex and defined throughout by an elevated and entire margin. Kli/tra
elongate, distinctly more than twice as long as wide, one-half wider than the
prothorax, the sides parallel and nearly straight, gradually rounded behind in
apical third to the feebly oblique apical truncature, w Inch is defined by a small
dentiform projection; humeral impression distinct, the others wholly obsolete;
disk finely, closely punctiite, the vestiture moderate in length but rather coarse
and dense as usual, assuming tints nearly corresponding to the ground color;
erect setaj somewhat short, sparse and not very conspicuous. I^ength 3.6-3.8

adjoining surface scarcely fit all raodified. The female difters
somewhat, having the thoracic process slightly wider and just
noticeabl3' narrowed at base, the elytra barely twice as long as
wide and very broadly and obtusely rounded behind, and the
elytral maculation paler and more suffused. In some of its
characters pictus recalls sem'atus, the anterior fascia being a
coalescent variation of the short dashes of that species, but the
elongate, parallel elytra and non-dentellate thoracic process will
always readily- distinguish it. It is difficult to understand how
such a conspicuous form as this could so long have been over-
looked ; it is represented in my cabinet by five individuals.
MECYNOTARSUS Laf.
The differences between this genus and Notoxus are very radi-
cal, in spite of the general similarity of facies and possession of
the pronotal process, which is so eminently characteristic of the
latter ; in Mecynotarsus it is even more elaborately developed
than in Notoxus. But in Mecynotarsus the tarsi are extremely
long and filiform, with the penultimate joint cylindrical and un-
modified. The body is always small and of elegant form, and the
upper surface is devoid of the erect tactile setje so evident in
Notoxus. Our species may be known by the following charac-
ters, elegans differing almost subgenericallj^ from the fii'st three : —
Upper surface clotlied with fine sericeous pubescence; eyes large; antennae
very slender; thoracic horn finely and closely crenulate.
Elytra devoid of median darker area. Atlantic Coast.
Prothorax broadly rounded throughout at the sides, widest scarcely behind
the middle; elytra very nearly twice as long as wide. Length 2.0 mm.

Upper surface clothed with elongate parallel and decumbent scales, which are

The first two species and probabl}^ also the third, have the pro-

four minute setigerous tubercles, the two median more approxi-
mate and limiting a feeble depression, which is relatively much
narrower in Jlavica)is than in the more slender candidus.
M. fiavicaii!^. — Elongate-oval, convex, ahitaceous, pale albido-flavate
throughout, the eyes deep black and \ery cons])icuous; vestiture very short,
dense and closely decuni1)ent giving a whitish bloom. Head longer than wide,
broadly and very feebly concave, finely, closely punctate; eyes large, convex
and prominent, at much less than their own length from the base; antennae
slender, filifonn, nearly two-thirds as long as the body. Prothorax wider than
long, very much wider than the head, convex, subangularly rounded at the
sides behind the middle; base two-thirds as wide as the disk; horn large,
longer than wide, narrowly parabolic in outline, feebly constricted at the im-
mediate base; edges rather finely crenulate; crest feebly elevated, narrow, de-
fined feebly by detached elongated tu>)ercles. Eli/tra three-fourths longer than
wide, barely two-thirds wider than the prothorax, parallel and nearly straight
at the sides, arcuately narrowed and obtusely parabolic in apical third, with a
broadly cuspiform sutural notch; humeri rounded; disk minutely, very
densely punctate like the pronotum. Under surface minutely, densely punc-
tate and pubescent, dull, the legs rather long, slender. Length 2.25 mm.;
width 0.8 mm.
New Jerse}^ (nearly opposite Philadelphia).
The fifth ventral of the male has a rounded and rather deep
impression, which is larger and stronger than the homologous im-
pression of candidus. Flavicans is a larger and evidently stouter
species than candidus, and ma^^ be readily distinguished b}' the
prominent sides of the prothorax.
Xylophilin.e.
The heterogeneous components of this subfamily, while bound
to the Anthicinse by certain characteristics of facies, differ very
radically in tarsal and abdominal structure, and also in the form
of the labial palpi as indicated in the table previously given. The
species are all small and generall}- quite minute, but the profound
structural differences of the genera lends great interest to them
from a morphological standpoint. The species of the various
genera adhere closely in general appearance to the t^'pe form, and
will prove to be rather numerous. They are, however, quite rare
in cabinets at present, chiefly because no systematic methods
have been pursued in collecting them, the onl}' exception to this
known to me being the cabinet of Messrs. Hubbard and Schwarz,
which contains good series of many species, carefully collected
Coleopterological Notices^ VI. 7*73
in Florida, in Avhich region they seem to particularly abound.
There are, however, also a large number of northern Atlantic
species, but only a single one is known at present from the Pacific
coast. A considerable number of Mexican species have been re-
cently described by Mr. Champion.
I have no hesitation whatever in separating our species into
numerous genera, the generic characters being as pronounced as
in almost any other group of Coleoptera, but as the types of
Xylophilus, Euglenes and other of the older genera are unknown
to me at present, I am forced to give them all distinct names, the
probability being that none of them will prove entirely identical
with any hitherto described.* These genera are the following : —
Muzzle not prolonged before the point of antennalinsertlon 2
Muzzle prolonged; body very minute 11
2 — Head constricted at base; epistonial suture deep and distinct 3
Head not constricted at base 10
3 — Basal joint of the hind tarsi very long 4
Basal joint of the hind tarsi short, much shorter than the remainder 9
4 — Eyes deeply emarginate 5
Eyes feebly or moderately emarginate, the notch sometimes almost obsolete.. .6
5 — Head deeply sinuate at base; antennie thick and subcylindrical, the second
joint obliquely truncate; vestiture short, matted and duplex. ..Eloiilis
Head truncate at base; vestiture long, stift' and simple.
Antennae inserted within the eye on the emarginating canthus, strongly
flabellate in the male, not observed in the female Eiueliniis
Antennse simple in both sexes, inserted just without the eyes, -which are
generally not quite .so large Zoiiaiites
6 — Prothorax not prominent at the sides; eyes more or less coarsely faceted as
usual 7
Prothorax angulate and prominent at the sides anteriorly 8
7 — Second and third antennal joints small PlloiiialllS
Tliird antennal joint elongate.
Prothorax as wide as the head; last antennal joint abruptly enlarged.
Ariotiis
* In general neatness of appearance, diversity of structure and individual
rarity the Xylophilinse may be fancied to bear much the same general rela-
tion to the other Anthicidaj that the Eucneminaj bear to the rest of the Elater-
idse, and the Aveights of the two subfamilies, with regard to the remainder of
their respective families, are about equal. The ratio of species to genera among
our representatives of Xylophilinae is at present nearly 3, while among the
Eucneminaj it is only about 2.5, and even in the Cerambycidaj it is not quite
3.5. The absolute value of the generic differences I hold to be about equal in
the three cases.

EIvO]¥US n. gen.
In this genus the body is oblong, moderately convex, opaque,
coarsely, densely sculptured and clothed with short confused
pubescence intermixed with longer and more erect hairs. The
head is deeply constricted and strongly sinuate at base, the
fourth joint of the maxillary palpi moderately large and in the
form of a right-angled triangle, and the last joint of the labial
very large, slightl}' transverse, suboval, truncate at apex and
deeply concave, with the surface minutel}^ granulose and sensi-
tive beneath. The e3'es are large, deeply emarginate, coarsel}'
faceted, conspicuously- pilose and distant from the base; antenuiie
long, more or less thick, cylindrical and roughl}' sculptured, with
the second joint transverse, short, as wide as the first but wider
than the third and obliquely truncate at base, the last joint
obliquely pointed or bent.
The middle coxa; are well separated, the posterior subcontigu-
ous, the basal process of the abdomen rather acute, the basal seg-
ment of the latter having the dividing suture visible in the mid-
dle very near the base and almost tangent to the acetabula. The
posterior tibist are devoid of terminal spurs, but have instead a
terminal tuft of yellow seta? externally ; the basal joint of the
hind tarsi is extremely long, bent toward base and finel}' subcari-
nate beneath.
Goleopterological Notices, VI. Y75
The male sexual characters are extraordinaril}' developed, and
affect principall}^ the entire surface of the abdomen and the pos-
terior legs. The basal segment of the abdomen is impressed and
more densely pubescent near each side of the body, apparently
in both sexes. The pronotum is evenly convex, not at all im-
pressed at any point, and is narrowed in front. The epistomal
suture is very coarse and deep. The three species known to me
ma}' be recognized as follows : —
.Short pubescence of the eh'tra not forming a median fascia bnt more or less
condensed along the suture.
Front very densely punctate and granulose; epistoma densely pubescent;
eyes separated by their own width; body large and stout. ..1. princeps
Front sparsely punctate and with scattered minute, acutely elevated gran-
ules; epistoma smooth, vdt\\ a few remote and feeble granules; eyes much
more approximate on the vertex, separated by scarcely three-fourths of
their own width; body smaller and naiTOwer 2. 1)asalis
Short and pale pubescence forming a faint zigzag median fascia and an apical
spot; last autennal joint elongate and bent, at least in the male; eyes still
more narrowly separated 3. iiebulosus
The elytral punctures in this genus are not only coarse but
very deep, and their floors are flat and highly polished.
1. E. priiicep^ n. sp. — Oblong, convex, dull, brownish-black throughout,
the tarsi, palpi and base of the elytra, more broadly at the sides, pale testa-
ceous; pubescence short, moderatelj^ dense, the short hairs strongly condensed
along the elytral suture. Head wider than long, thick, convex, very densely
punctate and granulose, the antenna; thick, fully two-fifths as long as the
body, gradually incrassate from the third joint, the joints feebly obconical,
separated and perfoliate, transverse toward apex, the eleventh oblique and not
quite as long as the preceding two together. Prothorax distinctly narrower
than the head, a little wider than long; sides parallel and nearly straight in
basal half, then strongly convergent to the arcuate apex, which is scarcely
more than two-thirds as wide as the base, the latter very feebly arcuate; disk
evenly, moderately convex, densely sculptured like the head, each puncture
with an attached setiferous tubercle. Scutellum large, triangular, narrowly
truncate at apex. Elytra two-thirds longer than wide, not quite twice as wide
as the prothorax, parallel and nearly straight throughout at the sides, broadly
but evenly rounded at apex, the humeri narrowly rounded, well exposed at
base; disk feebly impressed at each side of the suture throughout the length,
also feebly so within the humeri, the punctures very coarse, deep and dense.
Ahflomen finely, moderately closely punctate, finely pubescent, the legs com-
paratively short, not very stout. Length 3.0 mm.; width 1.25 mm.
Canada (Ottawa).
The type is a female, taken at the indicated locality by " W.

Color and sculpture as in the preceding, the basal pale space
of the elytra large at the humeri, but only faintly extending
across the scutellum, the latter more broadly truncate ; pubes-
cence more narrowly and indistinctly- condensed along the el3'tral
suture. Head transverse, the eyes at fully three-fourths of their
own length from the base, and about as prominent as the tem-
pora, the latter rounded ; antenntie nearly one-half as long as the
body, the tenth joint transverse, the eleventh short, conoidal,
much shorter than the two preceding. Prothorax much narrower
than the head, fully as long as wide, otherwise as in princeps.
Elytra nearly three-fourths longer than wide, fully twice as wide
as the prothorax, feebly impressed along the suture, very coarsely,
deeply and densely cribrate. Length 2.8 mm.; width 1.0 mm.
Virginia and Illinois, — LeConte. This species is also represented
in my cabinet by a single female, and is rather closely allied to
jyrinceps, differing in its narrower form, more elongate and less
robust antennjB, which are more rapidly and apicalh' incrassate,
in its much less widely separated eyes, and other characters. In
the male of both species the apical joint of the antennae is prob-
ably much more elongate.
3. E. nebulosus Lee— Trans. Am. Ent. Soc., 1875, p. 175 (Xylophilus).
Moderately stout, convex, opaque, black, the abdomen and
elytra brown, the latter slightl}' paler at base ; tarsi and palpi
pale ; pubescence moderatel}' dense, the longer hairs of the elytra

pointed, bent and distinctly longer than the two preceding, the
tenth fully as long as wide. Prothorax aliout as long as wide,
onl}- ver^' slightly narrower than the head, narrowed in apical
half, the arcuate apex scarcely more than three-fifths as wide as
the base. Elytra two-thirds longer tlian wide, twice as wide as

Pennsylvania. The two specimens before me are males, and I
have not seen the female. The abdomen in the male is thrown up
in a broad flat central region, involving the first three segments,,
the elevation gradually becoming free, porrect and laminate-
toward the apex, which is truncate, extending slightly over the-
fourth segment, the latter being deeply and transversely exca-
A^ated. The hind thighs are greatly dilated, clothed on the inner
face with short and extremely dense brown pubescence, with a
subbasal excavation which is more finely pubescent, the hind
tibiae, and the intermediate to a less degree, arcuate, becom-
ing slightly thicker toward tip. The corneous sheath of the in-
tromittant organ is long, slender and veiy finely pointed. It is
probable that the female has the e3'es less approximate and the
terminal joint of the antenna shorter. There are few species of
Coleoptera having more radical and remarkable sexual characters
than this.
The surface of the head and pronotum is densely opaque, the
punctures being extremely deep and closel}^, polygonally crowded,
not intermixed with tubercles, as they are in princeps and basalis.
EMELI^US n. gen.
The two species separated under this name have the eyes large,
subbasal, emarginate through about two-thirds of their length,
coarsely faceted, coarsely and sparsely pilose, with the antennm
inserted on the canthus, the third joint of the latter much elon-
gated and the succeeding joints flabellate in the male. The base
of the head exhibits no sign of the deep median sinus of Elonus,
and the sculpture and vestiture of the body are quite different.
The epistomal suture is much less coarse, the terminal joint of
the maxillary palpi nearly similar but the last joint of the labial
is auriculate, transverse, pointed within, with the edges of the deep-
ly concave lower surface pilose. The middle cox?e are more
narrowly separated than in Elonus, and the dividing suture of the
first abdominal segment is very strong throughout the width at
some distance behind the coxtxi. The posterior tibiic are obliquely

truncate at tip, with a few stiff terminal setx externally which
scarcely have the nature of spurs ; the basal joint of the tarsi is
ver}' long and slightly bent toward base. In the male the hind
legs are much longer and proportionall}' a little stouter than the
others, but there are apparentl}' no striking abdominal or crural
sexual characters. The species may be known as follows : —
Eyes separated by fully one-third of their own width 1. inelslieiiiieri

These species are each represented in my cabinet by a single

autennse pale throughout, except the basal joint which is piceous-black ; vesti-
ture moderate and subeven in length, subdecumbent, rather dense, very coarse
and silvery in the pale elytral areas, finer and brownish in the darker spots
and fascia?. Head transverse, the eyes occupying virtually the entire surface
as seen vertically, except a triangular median area at base, which is very
densely punctate and opaque; antennas three-fifths as long as the body. Pro-
thorax much narrower than the head, scarcely as long as wide, the sides par-
allel and straight in basal two-thirds, then strongly obli(iue to the rounded
apex, which is scarcely three-fifths as wide as the base; disk not impressed, very
densely, subtubercularly punctate and opaque, the pubescence very coarse and
silvery in a large median area toward base and also at the sides. Elytra nearly
as in melsheimeri, but much more densely punctate and duller, the blackish
spots and zigzag fascia? much better defined; omoplates evident. Abdomen
rather finely but strongly and somewhat densely punctate, the legs rather
long. Length 2.1 mm. ; width 0.8 mm.
Florida (St. Nicholas).
Differs greatly from melsheimeri in its much larger ej^es,
denser sculpture and more variegated pubescence. The antennae
in both of these species become discontinuous in direction from
the apex of the third joint, each joint after the third to the tenth
bearing a very long slender pilose internal ramus, and gradually
becoming longer and thinner in form, the eleventh very much
longer, constituting by itself the outermost ramus of the flabel-
lum. and having a remarkable knob-like enlargement near its
apex which is much larger and more noticeable in ashmeadi.
I have dedicated this interesting species to Mr. W. H. Ashmead

ZOIVAIVTES n.'gen.
This genus is rather closely allied to Emelinus, but differs in
having the suture dividing the basal segment of the abdomen
completely obsolete toward the middle and onl}^ feebly indicated
at the sides, in the smaller and normal punctures, in the trans-
versely parallelogramic prothorax which is subequal in width to
the head, in the generally shorter, more oval and convex form of
the bod}-^, and in the simple antennae of both sexes. The eyes are
large, coarsely faceted, coarsely and sparsely pilose, deeply, sub-
angularly emarginate and generally at a slight distance from the
base, the tempora being much less prominent and rectangular.
The epistomal suture is rather fine, the fourth joint of the maxil-
780 Coleopterological Notices, VI.
laiy palpi somewhat more than right-angled, the terminal joint of
the labial nearly as in Emelinus. The antennae are moderate in
length, somewhat slender, with the third joint moderate in length,
the eleventh swollen at the middle and very obliquel}^ pointed.
Tibiae trnncate, with a slender setiforra internal spnr at apex.
The eight species known thus far may be distinguished as fol-
lows : —
Elytra each with a submedian spot of black and another between basal third
and fourth, the two generally united at the sides 1. iiullifer
Elytra with a narrow dark median fascia widely interrupted at the suture,
generally without trace of a scutellar spot; small species.
Median fascia very narrow and strongly oblique, usually resolved into two
small spots on each elytron; head pale 2. signatllS
Median fascia wider and transverse; head blackish 3. suMasciatus
Elytra with a broad median fascia of black, not interrupted at the suture ;
larger species.
Fascia broadly produced posteriorly along the suture for a short distance.
Legs pale flavo-testaceous throughout 4. ]iii1)bai'di
Legs in great part black; body stouter 5. scliwarzi
Fascia not at all produced posteriorly; antennit? pale flavo-testaceous
throughout.
Dorsal pygidial plate of the female with four lamellate teeth on the in-
ner surface at apex; scutellum large 6. fasciatus
Dorsal plate with three teeth in the female; scutellum relatively small.
7. tricuspis
Elytra and entire body piceous-black throughout 8. ater
The sexual characters are quite feeble throughout, and affect
principally the hind femora and antenna?, the former being some-
what thicker in the male, but without a dense internal pad of pu-
bescence, and the latter slightly shorter and thicker in that sex.
The elytral punctures, though generally rather coarse, are always
simple and impressed, and do not have the flat polished floors ob-
served in Emelinus.

District of Columbia. Hubbard and Schwarz.
The single t3'pe is a male having the slender apex of the o3deagus
protruded, but the sexual characters are not very pronounced, the
fourth ventral being perfectly simple, unmodified on the disk and
only slightly longer than the third, the hind femora moderately
inflated. It is probable that the female has the last joint of the
antennffi less sw^ollen and distorted.
5. Z. scliwarzi n. sp. — Resembles the preceding, but differs in its
broader form and shorter elytra. Head transverse, the eyes large; antennje
moderately thick and of tlie usual length. Prothorax transversely subquad-
rate, strongly punctate. Elytra scarcely two-fifths longer than wide, parallel
and just visibly arcuate at the sides, narrowed in apical third, the apex rather
narrowly rounded; intra-humeral impression extending obliquely and quite
distinctly almost to the middle; punctures somewhat coarse, moderately close,
becoming toward finer apex. Length 2.2 mm. ; width 0.9 mm.
Florida ( Biscay ne Bay ). Hubbard and Schwarz.
The under surface is dark brownish-rufous throughout, the
elytra paler, rufo-testaceous, with a transverse median fascia of
black which is more than one-third as wide as the total length,
broadly produced posteriorly along the suture for a short dis-
tance ; each elytron also has a small black spot at the middle of
the base; the legs are black, the femora picescent at base, the

Pennsylvania. The single specimen, which I took near Phila-
delphia, appears, from the small portion of the genital apparatus
protruding, to be a female ; the fourth ventral has a rounded deep
and foraminiform central fovea, from which a stout seta projects
obliquely ; the fourth ventral is a little shorter than the two pre-
ceding together, broadl}- rounded or subtruncate at apex, and, on
its inner surface, there is a row of asperities along the apical
margin projecting inward; on the inner surface of the dorsal
plate there are four large lamelliform teeth at the middle of the
apex, also projecting inward; these, in conjunction with the
asperities of the lower plate, possibl}^ form a kind of clasping ar-
rangement,

Iowa (Iowa Cit}^), Mr. Wickham.
The two specimens serving as types are apparently females,
with the fourth ventral one-half longer than the third, and having
a rounded central setiferous foramen, the inner surface at apex
with a series of about twelve small setiferous spicules, which are
inwardly erect, the inner surface of the dorsal plate with three
large lamelliform teeth at the middle of the apical margin and
projecting inward.
This species is the largest of the genus, and, though allied
closely in general appearance to fasciatus, may be distinguished
by its more elongate elytra, smaller scutellum, larger size and
other characters.

Texas (Waco). I am not at all sure of the generic position of
this species, the above hastj^ notes having been taken from the
unique type, which is now inaccessible. From an outline sketch
made at the same time, the eyes appear to be much smaller than
usual in this genus, and are at some distance from the base, and
the prothorax is gradually narrowed behind from near the apex,
which is also a character foreign to the other species,

Yestiture of the bod}' very short, decumbent, dense, consisting of
very minute, and longer and sparser hairs, intermingled.
This genus is quite distinct, and is the onl}- one which occurs
in both the Atlantic and Pacific coast faunal regions. The
species may be known thus : —
Smaller and narrower, more opaque, the punctuation much denser; sides of
the pvothorax not at all prominent behind the apex...l. brunnipennis

California (near Montere}^).
A specimen from Arizona is much smaller, witli narrower and
more oblong el)'tra, which are more coarsely punctate and still
more polished, the punctures more impressed ; it probably repre-
sents a very closely allied species and is not included in the

brunnipennis in its more robust form, more shining surface,
longer antennae and numerous other characters.

The body iu tliis genus is nariow, elongate and subparallel, the
head not wider than the prothorax, with the epistoinal suture dis-
tinct, the base transversely truncate and broadly arched, the eyes
moderately large, rounded, subglobular, very coarsely faceted,
scarcely at all setose and with only the slightest evidence of a
minute emargination, the tempora very short, rounded and much
less prominent. Last joint of the maxillary palpi short, very
broad, the basal angle being very obtuse, of the labial moderately-
large, transverse!}' subsecuriform, with the apex obliquely- beveled
and sensitive, differing completely from the form seen in the pre-
ceding genera. The antennje are rather short, slender, incrassate
toward apex. The prothorax is transversel}^ and feebly obtrape-
zoidal, not impressed, the scutellum small, narrowly trapezoidal,
and the elytra parallel and devoid of distinct impressions. The
middle coxae are narrowly separated, the posterior only slightly
more widely so, the hind femora not dilated, the corresponding
tibiae devoid of terminal spurs but with a porrect terminal plate
internally, apparently composed of agglutinated setaj ; tarsi
slightly shorter than the tibiae. The basal segment of the abdomen
is not quite as long as the remainder, without trace of dividing
suture, the second and third equal, and the fourth much longer
than the third.
Our two species differ decidedly and may be mutually dis-
tinguished as follows : —
Hc<ad punctate; elytra with a terminal black area which is produced anteriorly
along the suture, the short vcstiture intermixed with longer and coarser

differs from quei^cicola in its broader and more oval form and
much larger eyes, in addition to the characters of the table.
PSEIDARIOTUS n. gen.
The rather minute species separated nnder this name have a
short obese and convex form of body, polished elytra, and a ves-
titure wliich is suberect and composed of hairs Avliicli dilfer dis-
tinctly in length and w^hich are confusedly intermingled. The
head is only very slightly wider than tlie prothorax, the e^'es
somewhat large, convex, extending to within an extremely short
distance of the base, rather finely' faceted and with a small but
distinct anterior notch ; thej^ are distinctly and rather densely
pilose. Epistoraal suture distinct. Last joint of the maxillary
palpi moderately large, right-angled, that of the hilnal unusually
developed, short but extremely transverse, with the subtruncate
apex concave and spongy, differing noticeably in form from any
of the previous genera, but resembling somewhat that of San-
dytes. Antenna' slender, gradually and feebly incrassate, mode-
rate in length, i)ilose. Prothorax feebly constricted at the sides
of the apex, the disk somewhat uneven, transversely and slightly
tumid behind the middle and tumid near the sides at apical and
basal third. Scutellum broadly triangular, subtruncate at tip.
Basal segment of the abdomen distinctly shorter than the remain-
der, Avith the dividing suture only slightly indicated near the sides

The elytra are black, ornamented with pale spots.
The two species known to me may be distinguished as fol-
lows : —

middle 1. iiotatus
Pronotum polished ; posterior pale spots at apical fourth 2. amicus

probably very slight.

1. P. iiotatus Lee.— Pioc. Acad. Nat. Sci., Phila., 1855 p. 276 (Xylo-
philus).
The unique type of this species is not before me at present, but
from a sketch made some years ago, the posterior pale spot of the
elytra is situated at about apical third ; this, in conjunction with
LeConte's statement " capite thoraeeque opacis, confertira punc-
tulatis," and the fact that the type was taken in Habersham
County, in the extreme northeastern and submountainous parts
of Georgia, a region zoologicall3^ altogether distinct from the
tropical southern tip of Florida, leads me to believe that notatus
will prove to be quite distinct from amicus. The generic diagno-
sis is taken from the latter. The type of notatus is 1.4 mm. in
length ; width 0.05 mm.
2. P. amicus n. sp. — Oval, convex, polished, rufo-piceous, the legs and an-
temite pale fla\ate; elytra black, graduallj' pale toward apex, each with a
large irregular and transversely reniforni spot at basal fourth, extending at the
sides to the humeri, and another large subquadrate spot at apical fourth, of

YANOIVUS n. gen.
The body in Yanonus is moderately elongate and subparallel,
clothed with ver}' short decumbent pubescence, the head trans-
versely truncate and moderately elevated at base, with the eyes vari-
able but always semi-nude, the setoe being extremely minute; they

are minutely and feebly emarginate and generally moderately
coarsely faceted, the facets in one group becoming extremely
large, however. The epistomal suture is distinct and the epi-
stoma simple at apex, except in ivickhaini, where it becomes iinely
beaded. Last joint of the maxillar}' palpi large, extremely' di-
lated, bent transverselj' on its compressed side in the form of a
bow, with the basal angle broadly obtuse, that of the labial
moderate in size, thick, the apex truncate in the form of a flat cir-
cular or inwardly pointed disk, which is densel}' pubescent and
sensitive. Antennne moderate in length and thickness, gradually
and generally feebly incrassate, the third joint much longer than
the fourth, the second small, eleventh moderate in size, conoidal
and normal. The middle coxa? are well separated, the posterior
still more widely, the posterior femora not noticeably dilated but
having beneath in both sexes an elongate area, clothed with dense
erect and papillose pubescence ; tibiiij narrowed toward base, the
internal terminal spurs extremely minute and setiform, sometimes
apparently obsolete; tarsi moderately long, very slender, the
basal joint greatly elongate. Abdomen with the basal segment
very large, without trace of dividing suture, the fourth much
longer than the third. Prothorax narrowed in front, generally
transversely impressed on the disk near the base. Scutellum
small, narrowly trapezoidal. Elytra oblong-oval, the flanks rather
abruptly vertical. Sexual characters not determined and ap-
parently extremely feeble.
The species in ray cabinet ma}^ be separated into four groups,
as shown by the following table : —
Eyes extending virtually to the base of the head, the tenipoia extremely short.
Eyes moderate in size and coarseness of ^lanulation, tlie antennaj widely
separated at base.
Elytra clotlied sparsely with very short, coarse and decumbent hairs. (I)
1. calvescens
Elytra rather densely clothed Avith short line pubescence, the hairs all
similar and of e(iual length ; transverse subbasal impression of the
pronotum distinct and uninterrupted. ( 11)
Eyes separated by fully twice their own width, the vertex flatter and
densely punctate.
Larger species, the transverse impression of the pronotum feeble in
profile and very near the base 2. piceus
Smaller, the transverse impression deeper and larger in profile, oc-
cupying more than ba.sal third; elytral omoplates rather smaller

long, parallel and distinct behind them; antenna) longer, inserted at some
distance from the eyes and moderately separated at base; impressions of the
pronotum and vestiture nearly as in t\\Q piceus group. (IV) 8. wickliailli
All but one of these species are represented before me by a
single specimen, and the extent of the genus will be greatl}^ in-
creased by future collecting. These species are, however, widely
distinct among themselves, and the limited number of examples
is, for this reason, a matter of but little consequence.
1. V. calvesceiis n. sp. — Oblong-elongate, feebly convex, moderately
shining, blackish-castaneous throughout; vestiture extremely short, sparse
and rather coarse, closely decumbent. Head strongly transvei'se, finely retic-

punctate, the eyes large, globular, separated by three-fourths more than their
own width; antennae somewhat stout, feebly and gradually incrassate through-
out, about one-third as long as the body, the tenth joint slightly transverse,
the eleventh conoidal, not as long as the two preceding. Prothorax distinctly
narrower than the liead, obliquely narrowed in apical third, about one-fourth

Ontario (Severn). The original description of Dr. Hamilton is
altogether insufficient, and I am somewhat doubtful of the refer-
ence, as the medium of publication omits signature marks. The
specimen before me lacks the head and all the legs, and is one of
the two original ty[)es recentl}^ sent to me by the author ; the
above description of the head is from pencil notes and diagrams
taken from the best preserved of the t3qoes. This species is some-
what closel}^ allied to piceus, but is evidently distinct.

New York. Mr. H. H. Smith.
This species is allied to the preceding, but difli"ers conspicu-

fectly simple ; the fourth ventral is about two-thirds longer than
the third, and is evenly and somewhat narrowly rounded.
6. V. sagax n. sp. — Narrowly oblong, moderately convex, black, the legs
testaceous, with the intermediate femora slightly, the posterior deeply, black-

A rainnte and narrow species, with globose and ver}- coarsel}'
faceted eyes and opaque, pruinose integuments; it is readily- dis-

Wisconsin (Bayfield). Mr. H. F. Wickbam.
A small but veiy distinct species to be readily known b^- its
smaller eyes, longer tempora, longer antennjje and completely
black legs. It is much more closely allied to piceus than to the
huronicus group, and is placed at the end of the genus solely for
taxonomic reasons.
TAlVirOTES n. gen.
The members of this genus greatly resemble Vanonus in gen-
eral form and habitus, and the sculpture and fine, even, decumbent
vestiture are exactly as in the piceus group of that genus. The
head is only very slightly wider than the prothorax, the eyes
moderate in size, coarsely faceted, with very short -setse, which
are much more evident in densus than in lacustris, rather distant
from the base and minutely, feebly emarginate anteriorly. Epi-
stomal suture distinct, the epistoma narrow!}- coriaceous at apex,
and apparently with an adjacent terminal beaded segment which,
however, may be a basal margin of the labrum. Palpi as in
Vanonus. Antennae somewhat short, abruptl}' clavate, the club
parallel and five-jointed. Fronotum biimpressed near the base.
Scutellum moderate, trapezoidal. Middle coxi\? moderateh^ sepa-
rated, the posterior not more widely so. Abdomen with the basal
segment large, much more than equaling all the others combined,
the fourth var3ing in length, the first three segments margined at
apex with a ver^^ wide pale and coriaceous border. Legs slender,
the hind femora completel}^ devoid of the papillose pad of Vano-
nus, but having beneath near the apex, and in both sexes, a large
lamelliform tooth.
Our two species mutually differ to a great degree, but are per-
fectly congeneric, as shown b}' the capitate antennae and toothed
hind femora ; they ma}^ be known as follows : —
Goleopterological Notices, V^I. 799

in its much shorter antenna^, which, in the latter, are said to be
three-fourths as long as the body. Excepting AxylopMlus yuccae,
this is by far the most minute xylophilide thus far discovered in
the United States ; it probably occurs on maritime plants along
the shore line of the Gulf of Mexico.
GAlVASCrS n. gen.
The complete lack of a basal cephalic constriction, which ren-
ders this and the following two genera so aberrant, is somewhat
suggested in Cnopus, where the constriction is carried forward,
leaving the basal part of the head on a level with the pronotura.
The body is very obese and convex, clothed with a short coarse
decumbent and matted i)ubescence, variegated in color and inter-
mixed with sparser, semi-erect hairs arising from the larger punc-
tures. Head vertical or slightly inflexed, broadly arcuate at base,

where it is in close contact with the prothorax, the vertex flat;
epistomal suture fine but distinct. Eyes large, coarsel^^ faceted,
distinctlj^ pilose, occup3ang the entire sides of the head and
touching the prothorax at base, having a small but distinct an-
terior notch. Antennae moderate in length, distinctly and grad-
ually incrassate. Last joint of the maxillary palpi moderate in
size, short, transverse, the basal angle broadly obtuse, that of the
labial transversely excavated at apex and well developed. Scu-
teilum rather large, equilatero-triangular, narrowly truncate at
apex. Middle coxse moderately separated, the posterior a little
more widely. Abdomen with the basal segment fully as long as
the entire remainder, divided before the middle by a fine but dis-
tinct suture throughout the width, the suture anteriorly arcuate
in the middle ; remaining segments short and equal. Legs some-
what short and stout, the hind femora onlj^ slightly stouter, finely
subcarinate beneath ; tarsi moderate, the basal joint normall}"
elongate.
Although this genus is one of the most distinct of the sub-
family, the species which compose it are closely allied and will
prove a difficult study ; the three which seem to be indicated by
the material in my cabinet may be recognized as follows : —
Elytral puncturas distinct and well separated, not concealed or obscured by
the vestiture; elytra shorter and oval, the fuscous markings very much
confused and scarcely at all definable.
Eyes largei-, separated by their own width 1. veiitricosus
Eyes separated by slightly more than their own width; head relatively
smaller and more convex 2. opiums
Elytral punctures very dense and closely crowded, more or less obscured by
the vestiture, the elytra longer and more oblong, with four distinctly de-
fined irregular black spots at the middle of the disk; eyes separated by
much more than their own width 3. palliatus
Other species exist in collections, but I am not able to collate
them at present. The sexual characters appear to be extremely
slight.

North Carolina. The oval and convex form of body, indefin-
able mottling of brown markings, and distinctly defined el3"tral
punctures, will serve to identify this species, which is more north-

Readily distingnishaljle from the preceding by its smaller size,
more shining surface, smaller head and prothorax, the latter
more transA'^erse, sparser punctuation and, especially, by the an-
tennal structure, the eleventh joint in venbncosiis not being
abruptly wider than the preceding. The single specimen serving
as the type is a male, and has a rather singular, abruptly pointed
form of intromittent organ, which, as in other species of the sub-
family, seems to be slightly asymmetric.
3. G, palliatlis n. sp. — Oblong-oval, convex, opaque, black beneath,
the antenniT;, tibiic and tarsi pale; upper surface pale, with the middle of the
])ronotuni transversely darker, and with black niuculation on the elytra, es-
pecially evident near the scutellum, along the flanks, and in four central spots;
vestiture very dense, obscuring the punetitation, more especially in the pale
areas. Head small, rather finely and moderately sparsely punctate, the eyes
separated Ijy nearly one-third more than their own width ; antenna; almost
one-third as long as the body, filiform, the last joint abruptly thicker, ob-

Body oblong, convex, the vestiture coarse, short, subdecum-
bent, rather sparse, with condensed patches of short matted white

unmodified, the hind femora but slightly dilated ; basal joint of
the tarsi normally elongate.
This genus, while related to Ganascus, differs greatly in anten-
ual structure, in its deeply emarginate eyes — the emargination,
however, not being so deep as in the first three genera of the
subfamily, — in its narrow and subcylindrical prothorax, and in
general habitus. There is but one species, as follows : —
1. S. ptinoides Schz.— Proc. Am. Phil. Soc, XVII, 1S78, p. 371 (Xylo-
philiis).
Polished, black, the antenntB, palpi and legs pale flavo-tes-
taceous, the intermediate femora slightly, the posterior deeply,
blackish ; interspaces between the punctures not at all reticulate ;
pubescence rather sparse and inconspicuous, except the coarser
short white hairs, which are distinct on the head, in two narrow
uneven pronotal vittse and at the sides toward base, and in a
transverse uneven spot at basal fifth of each elytron, and another
smaller and subsutural at apical two-fifths, these pubescent areas
apparently rufescent. Head densely, coarsely and deeply punc-

AXIXOPIIILIS n. gen.
Body oval, convex, sparsel3' clothed with moderately short
stiff and inclined hairs in a single uniform system. Head much
narrower than the prothorax, against the anterior margin of which
it is in close and even contact throughout, the surface forming
also a low short laminate hood, which does not extend over the
basal margin and which is continued narrowly behind the e^'es,
expanded again beneath and before the latter, where its glossy
concave surface is separated longitudinally from the extended
front by a tumid and sparsely hairy piece, extending from the
mandibles to the point of antennal insertion ; front broadly ex-
tended before the antennte and as long as the entire basal part of
the head. Epistomal suture coarse and very deep, the epistoma
small, subquadrate, two-fifths as wide as the extended front. La-
brum transverse, feebly convex, translucent, broadly' bilobed at
apex. Mandibles expanded with rounded outline, very thin and
laminate. E3'es large but sliort, very near the base, transversely
reniform, the anterior emargination containing the antennal base
very large and deep; facets coarse; setae distinct. Last joint
of the maxillary ]);ilpi moderate in size, securiform, of the labial
rather small though dilated and flattened. Antenna' slender,
moderate in length, the second joint somewJiat longer and stouter
than the first ; three to eight extremely slender and with very long
sparse setse ; last three joints very gradually thicker, elongate-
oval. Prothorax as wide as the base of the el^'tra, the humeral
angles of the latter not at all exposed at base. Middle coxjb well
separated, the posterior only a little more so, the abdominal pro-
cess narrowly rounded. Abdomen with the basal segment a little
larger than the entire remainder, the dividing suture visible at
the extreme sides only. Legs rather long, very slender, the hind

femora but slightly' thickened ; tarsi slender, distinctl>^ shorter
than the tibioe, the basal joint very much longer than the entire
remainder.
It is almost impossible to describe the remarkable double snr-
foce at the posterior margin of the head in an intelligible manner,
and, in view of this very aberrant structure, as well as the abnor-
mal anterior parts of the head and the broad base of the pro-
thorax, we must regard Axylophilus as the most specialized and
extraordinary type of the entire subfamily ; it is also the most
minute representative Avithin our faunal limits. The antemiie are
very similar in form to those of Trichopteryx.
1. A. yuccae n. sp. — Narrowly oval, polished, sparsely pubescent, piceous-
black, the head, pronotiim, base of the elytra and two fascia; just before the
middle and at mncal fourth respectively, pale testaceous; legs and antennae
testaceous, the hind femora l:»lackish except toward base and apex. Head
strongly inflexed, convex, longer than Avide, very minutely, sparsely punctate,
the eyes separated by one-half of their own width; antenna; about one-half
as long as the body. Prothorax four-fifths wider than long, very much wider
than the head, the sides feebly convergent and nearly straight almost to the apex,
then abrui^th' rounded and narrowed, the apex scarcely two-thirds as wide as
the base, the latter transversely truncate, with a small and feeble sinuation at
the scutellum; basal angles nearly right but blunt; disk moderately convex,
subexplanate toward the basal angles, strongly and rather closely punctate.

distinctly wider than at base ; sides arcuate ; apex obtuse and subtruncate ; disk
scarcely visibly impressed near the base, strongly punctate, the punctures well
separated. Abdomen more finely and densely punctate and pubescent toward
apex. Length 0.75-0.9 mm. ; width 0.45-0.5 mm.

This exceedingly interesting species was taken al)undantly by
Messrs. Hubbard and Schwarz, on plants of the genus Yucca.
OTIORHYNCHID.E.
The known forms allied to Dyslobus have become very nume-
rous by reason of recent collecting on the west coast, where they
constitute the most conspicuous and abundant otiorhynchide ele-
ment of the true Pacific coast fauna; they are especially nume-
rous and diversified in northern California and in Oregon. The
larger and more striking of these species, which I have set apart
for investigation at the present time may be assigned to four
o;enera as follows : —
810 Goleopterological Notices, VI.
First ventral sutiue very deep ami widely inijuessed, generallj' straight or
only sliglitly arcuate in the middle; second segment not longer than the
next two com])ined; met-ejiisternal suture distinct; scutellum very sliort
and ))road, not entering the elytral disk.
Elytral intervals not alternating in convexity Dyslobus
Elytral intervals distinctly alternating in convexity throughout the length.
Aiuiiesia
First suture fine, not broadly impressed and broadly arcuate.
Body squamose and pubescent; scutellum distinct; second ventral segment
mudi longer than the next two combined; met-episternal suture distinct.
Adaleres
Body scjuamose, the elytra without erect hairs, the intervals alternating
strongly in convexity and vestiture; scutellum extremely small, acute;
second ventral segment not longer than the next two combined; niet-
episternal suture completely obliterated IVomidus
In this sclierne Amnesia is limited to tliose speeiee having the
elytral intervals strongly- alternating in prominence, and it is
probable that other genera will ultimately have to be formed for
the smaller and more obscure species, such as rauca and decorata,
at present associated with them ; it is more than probable that
these forms can be included in Lepesoma of Motschulsky, although
L. californica can never be identified without the type. I can
find no essential difference in the form of the first ventral suture
and relative extent of the second segment, which were advanced
by Dr. Horn to distinguish Dyslobus from Amnesia (jranicoJIis,
the type of Amnesia, and the dilferential character which that
author attempts to draw from the internal terminal spur of the
hind tibije is wholl}' illusory and devoid of value in tliis particular
connection.
These four genera are in fact intimately allied among them-
selves, having the beak rather elongate, separated from the head
by a transverse depression and with the scrobes short, Hexed
gradually downward, broadening and becoming evanescent far
before the e^^es, and the ocular lobes at least moderately distinct
throughout. In the table given by Dr. Horn (Proc. Am. Phil.
Soc, XA'', p. 38), Dyslobus and Amnesia are widely separated b^'^
a number of genera which are not particularly closely related to
them, and in some cases widely dissimilar in important details of
structure.

invariably far distant from the prothorax. The three species ma}'
be distinguished as follows : —

The single specimen is apparently a female, judging by the
rather obese form of the body and the corresponding form of

This genus is very closely allied to Dyslobus, but may be dis-
tinguished not only by the alternately convex elytral intervals,
but by the greater prominence of the ocular lobes ; there is con-
siderable variation in the latter character, however, as is gener-
ally the case within generic limits, and the lobe is very much
shorter and less distinct in scnlptilis than in tumida. The species
known to me may be thus outlined : —
Elytra siiarsely but strongly tuberculose throughout, the sutural prominence
. at the summit of the apical declivity very pronounced tlliuida
Elytra not tuberculose, the sutural prominence moderate or feel)le.
Antennal funicle very long, much longer than the beak.

The description is taken from tlie female, the fifth ventral being
subtriangular and broadl}^ tumid along the middle. The male is
smaller and much narrower, with the elytra onh' about one-fourth
wider than the prothorax and the fifth ventral broadly rounded ;
I can perceive no radical differences in the legs, but the seventh
antennal joint is more decidedly longer and thicker than the
sixth.

ADALERES n. gen.
In general organization this genus is closel}' allied to Dyslobus,
differing in the fine and broadl}^ arcuate fii'st suture of the ab-
domen, and in having the second ventral much longer than the
next two combined. The apex of the hind tibite is oblique and
somewhat cavernous, but not distinctly unguiculate The two
species may be distinguished as follows : —
Humeri broadly rounded; elytral intervals not alternating in convexity or
only very slightly so near the apex; pronotum nearly smooth and densely
and evenly squamose ovipeiinis
Humeri oblique, obtusely prominent at a slight distance behind the base;
elytra more oblong and less oval, the intervals alternately more convex, the
suture prominently keeled at the posterior declivity; pronotum coarsely
granulosa and irregularly squamose liuiiieralis
This genus differs further from Dyslobus in having the first
three joints of the antennal funicle more or less distinctl}- elon-
gated. The serial punctures of the elytra are rather small, some-
what distant, each enclosing a rounded scale attached anteriorly.
A. OTipennis n. sp. — Elongate-oval, strongly convex, black, the anten-
naj and tarsi not paler; body very densely clothed throughout to the tip of

intermingled with numerous short erect hairs, the scales of the pronotum
slightly larger. Head large, convex, a little more than one-half as wide as the
prothorax, the eyes separated by slightly more than twice their own width ;
transverse impression moderately deep but evident; beak stout and long, not
quite twice as long as wide, slightly shorter than the prothorax, rather
abruptly and strongly dilated at apex, densel}^ squamose and nearly smooth,
the sculpture not evident, having a deep oval perforate dorsal fovea near api-
cal third, the median line thence finely and feebly carinate to the base; anten-
ntc long, the scape relatively rather short, only extending slightly upon the
eyes, the funicle very long, about as long as the prothorax, sparsely brist-
ling with long hairs, the basal joint slightly longer than the second, the latter
much longer than the third, which is in turn quite distinctly longer than the
fourth, seventh much longer than the sixth, obconical, club not longer than
the last two joints of the funicle, gradually pointed. Prolhomx relatively
small, not quite as long as Avide, the sides parallel and feebly arcuate, becom-
ing gradually almost straight in basal half, a little more convergent and
rounded near the apex, which is truncate and not quite as wide as the base;
ocular lobes small, moderately developed, briefly fimbriate, not quite attaining
the eyes; disk even, very obsoletely impressed along the median line and without
exposed sculpture. Elytra large, oval, rather more than one-half longer than
wide, more than three times as long as the prothorax and two and one-third
times as wide, the sides parallel and arcuate; apex acute; humeri broadly
rounded and obsolete, the basal margin not rounded but not prominent at the
sides, the base evenly sinuate in circular arc and equal in width to the base of the
prothorax; disk even, the suture becoming slightly prominent near the decliv-
ity, which is subvertical and feebly sinuate in profile; serial punctures small
and rather distant, each with a large scale; intervals wide, equal and very
feebly convex, very evenly and extremely densely squamose. Abdomen nearly
flat, densely squamose and pilose. Legs long, the anterior tibiae gradually bent
toward apex, sparsely denticulate within; posterior strongly dilated at apex;
third tarsal joint very widely bilobed. Length 10.8-14.5 mm ; width 4.3-
6.3 mm.
California (Sonoma Co.).
The description is drawn from the female, the fifth ventral be-
ing equilatero-triangular and nearlj- flat. The male is smaller
and much more slender, but does not differ in the form of the
legs. The prothorax in the male frequently has the sides feebly
convergent and nearly straight from apical fifth or sixth to the
base, and the fifth ventral is parabolic in 'outline. This species
does not appear to be rare, and I have before me a large series;
one specimen is marked " Mqjave Desert," but possibly in error.
In some individuals a sublateral sulcus of the beak is quite pro.
nounced, but the character is gradually evanescent.

]VO]fIIl>rS n.gen.
In this genus the elytra are oval, with the humeri rounded and
the basal margin rather obtuse at the sides, the beak and scrobes
as in Amnesia, the legs notably shorter and the hind tibiae not
distinctly mucronate. It diflers from Amnesia in the fine, broadly
arcuate first ventral suture, and, from all the other genera of the
Dyslobus group, in the obliteration of the met-episternal suture.
Coleopterological Notices, VI- 819
This genus has some relationship also with Phymatinus, but dif-
fers in its transverse frontal impression and shorter second ven-
tral segment. The single species known at present may be de-
scribed as follows : —
N. atoruptlis n. sp.- — Oval, convex, black, the antenna} not paler; tarsi

closing a large scale; suture rather more prominent behind, the declivity dis-
tinctly inflexed throughout in profile. Abdomen flat, densely clothed with a

or scale-like hairs. The unique type has the fifth ventral flat
and narrowly parabolic in outline. The contrast between the
evenly imbricate flat, and the dual vestiture of the convex inter-
vals, is very striking.
MELBOi\US n. gen.
Body elongate-oval and strongly convex, the surface nearly
smooth and densel}" squamose. Head not separated from the
beak by a transverse depression, having a minute interocular

double outer edge, tlie internal spur not distinct; tarsi well de-
veloped, spongy-pubescent beneath, the third joint broadly bi-
lobed; claws rather long, divergent.
Coleopterological Notices, VI. 821
As the supports of the deciduous pieces of the mandibles are
very prominent, I am disposed to place this genus near Diamimus.
It however differs greatl>' in having no vestige of a transverse
depression separating the head from the beak.
M. scapalis n. sp. — Narrowlj' ovoidal, black, the antennaj and tarsi not
paler; bodj' densely clothed above and beneath with rather small, oval, slightly

variegated with a slightly paler tint at the base and near the apical declivity
of the elytra, the scales intermingled throughout with numeroiis short, stout,
erect and brownish hairs which are unevenly arranged on the elytra. Head
scarcely one-half as wide as the prothorax, the eyes prominent and separated
by two and one-half times their own width; beak short and broad, one-fourth
longer than wide, two-thirds as long as the protliorax and distinctly longer
than the head, broadly impressed along the middle toward apex but not cari-
nate or otherwise modified; antennal scape densely clothed with narrow
whitish scales and bristling with sparse erect setae, the funicle equally bristling
and also clothed denselj^ with short stout appressed whitish hairs, the club
equally densely clothed with stout brown hairs and with a few short erect
setae. Prothorax not quite as long as wide; apex and base rectilinearly trun-
cate, the former distinctly' the narrower; sides evenly and distinctlj^ arcuate;
disk densely squamose, finely, sparsely punctate and with a feebly and indefi-
nitely impressed median line. Elytra three-fourths longer than Avide, not

The sex of tlie single type specimen is not determinable at
present. The posterior declivity of the elytra is rather deep and
nearly straight and vertical in profile, but the summit is not
prominent and joins the general outline of the upper surface by a
broadly rounded arc.

and from alternans by the equal rugosity of the elytral inter-
vals. The el^'tra are rapidly declivous behind in profile.

clothed with narrow pale brown scales intermixed with still narrower white
scales, and variegated on the elytra with small condensed spots of the brown
scales situated between the serial punctures; oblique sublatei-al vittiE of the
pronotum broad, yellow and uneven; elytra each with a more conspicuous
ochreous spot before the middle; abdomen with the sublateral yellowish spots
small. Head one-half as wide as the prothorax, densely squamose, the eyes
separated by about twice their own width, the fovea small and elongate; beak
large, distinctly longer than the prothorax and broader than in the allied
species, rather gradually dilated at apex, densely rugose, the median carina
fine and very feeble; antenual funicle bristling with long white hairs, the two
basal joints elongate and equal. Prothorax one-fourth wider than long, the
sides parallel, just visibly converging toward base, rounded anteriorly to the
feebly subtubulate apex, the latter fully three-fourths as wide as the base;
disk strongly and closely rugose and distinctly carinate. Elytra not one-half
longer than wide and almost twice as wide as the prothorax, the sides parallel
and nearly straight from behind the humeri to the middle, then gradually
convergent, the apex rather narrowly rounded; humeri rounded but unusu-
ally widely exposed at base; disk strongly and arcuately declivous behind,
the sutural angles very slightly but obtusely prominent; sculpture uniformly
finely, densely and strongly rugose, the serial punctures moderately large, dis-
tant and differing somewhat in .size. Length 10.5 mm. ; width 4.9 mm.
Colorado (Rocky Mts.).
This species is allied to geminatus and the European jyalustris,
but is distinguishable from the former by its more obese form,
stouter beak and coarser punctuation, more exposed humeri, more
declivous elytra and denser vestiture, and from the latter by the
rostral carina and many other characters.

Wisconsin (Bayfield, — Mr. Wickham) and Missouri. This spe-
cies has heretofore been confounded with the European palusb'is
Scop., which it somewhat resembles. It differs however from pa-
lustris, as represented by the numerous European examples be-
fore rae, in its more elongate form, much larger and more trans-
verse prothorax carinate along the middle, in its carinate beak
and much sparser vestiture. In the European species the beak
is still more slender, more cylindrical and is generally wholly
devoid of carina, though having occasionally a feeble trace, and
the pronotum is not carinate as it is in geminatuH.

the median impression at the base. Elytra more than one-half longer than
wide, generally not quite twice as wide as the prothorax, the sides parallel
and broadly rounded, the apex triangular with feebly arcuate sides which are
discontinuous with the sides from the umbones to the base, the sutural angles
individually augulate and separated by a pronounced notch; disk gradually
rounded and decli\ ous behind in profile, the tips explanate, the surface uni-
formly and finely rugose, the series alternately perceptibly more approximate;
serial punctures differing greatly in size and generally widely spaced, the
larger very elongate, deep, coarse and perforate. Legs long, the femora with
a ring of pale scales at apicjil third as usual. Length 10.3-12.0 mm.; width

the second funicular joint not quite twice as long as the first and but slightly
longer than the next three, the third longer than the fourth. Prothorax small,
slightly wider than long, the sides arcuate; apex truncate, more than three-

Colorado (Denver). Mr. Hugo Soltau.
A small but distinct species, quite conspicuous in maculation ;
it was taken by Mr. Soltau in considerable numbers. It may be
placed near rotu7iclicoUis in the arrangement recentl}^ proposed by
LeConte (Proc. Am. Phil. Soc, XY, p. 128.)
PLECTROMODES n. gen. (Phytonomini).
Body oval, very convex and sparsely pubescent, the elytra
acutely prominent at the sides behind the humeri. Head sub-
globular, moderately inserted, the eyes scarcely convex, trans-
verse, distant from the base, somewhat coarsely faceted, mode-
rately separated above, remotely so beneath, truncate anteriorly,
graduall}^ obtusely pointed beneath. Beak short, thick, cylindri-
cal, feebly dilated toward apex, the scrobes extending almost to
the tip, becoming partially visible from above, obliquely descend-
ing toward base and terminating at the lower angle of the eye.
Antenna; inserted near the apex of the beak, the scape slender,
extending to the base, enlarged at apex; basal joint of the funicle
830 Goleopterological Notices, VL
elongate, the second less elongate, three to seven short, graduall3^
wider, the club thick, oval, densely pubescent and four-jointed.
Mandibles stout, emarginate and bidentate at apex, the lower lobe
the longer and larger. Mentum trapezoidal, rather longer than
wide, not concealing the maxillary cardo ; gular peduncle long,
narrowed at base. Prothorax without ocular lobes. Anterior
coxae large, prominent, contiguous, the prosternum before them
short, sinuate and unimpressed ; middle coxre narrowl}' sep-
arated, the posterior also api)arently rather approximate. Abdo-
men flat, the two basal segments each as long as the third and
fourth together, the dividing suture moderately coarse and broadl}'
angulate ; fifth rounded and nearl3' as long as the two preceding
together,; posterior sutures coarse and straight. Legs well de-
veloped, the femora not clavate, with a small erect denticle beneath
beyond the middle; tibiae stout, longitudinally fluted, denticulate
within near the middle, the apex obliquely truncate with a double
outer edge and a strong internally projecting terminal spur; tarsi
stout, densely pubescent beneath, the first three joints rather
short, the last long; claws stout, completely connate in more
than basal half.
This singular genus is assigned to the Phytonomini onl}- pro-
visionally and for convenience, for it probably represents a distinct
though closely allied tribe. The peculiar dentiform prominence
at the sides of the elytra behind the base is suggested in a species
of Listronotus, described above in order to bring out this chai'acter,
and the beak with its scrobes and the formation of the prosternum
are all strongl^^ suggestive of that genus.
The two species before me may be distinguished as follows : —
Body stout, the elytra with two apical areas of dense pubescence, the promi-
nences at the summit of the declivity also densely pubescent.
paliidatiis
Body uiuch smaller and less robust, the elytra without the a])ioal pubescent
areas, the prominences at the summit of the declivity not pronounced and
scarcely more densely pubescent a riiiatus
The genus Plectromodes is probably confined to the United
States east of the Kocky Mountains, extending into the northern
parts of the Sonoran province, but not forming an element of the
tropical Mexican fauna.

This species is much smaller and narrow^er than paludatus, and
has the vjestiture still shorter and sparser but more evenly dis-
tributed. Two specimens.
The elytra have well marked but narrow epipleurae, extending
with equal width from beneath the post-humeral prominences to
the sutural angles. The met-episterna are nari-ow, with the su-
ture well marked and the metasternum is rather longer than the
first ventral.
RYSSEMATIIS Chev.

separated into two tolerably well defined subgenera, as show-n by
the following tabular statement : —
Alternate intervals of the elytra carinafe.

Iowa (Keokuk).
Readily distinguishable from lineaticollis by its stouter form,
still larger and more inflated protborax -which is much more

Indiana ?
Two specimens from the Levette cabinet without labels, but
probably taken in or near the above region. This species cannot
be confounded with any otlier, for, with a general facies sugges-
tive of lineaticollis, it has the oblique pronotal rugic of pahna-
collis and some other pubescent species. The prothorax is very
much smaller than in any other species of the lineaticollis group
of the genus. The types are probably- males.

Arizona rTu9son). Mr. Wickham.
This is a distinct species, readil}' distinguishable from any
other by the subcarinate intermediate intervals of the elytra ; the
eyes are even more approximate than in the lineaticoUis group.
There are before me two specimens which I refer to pubescens
Horn ; one of them is from an unknown part of Arizona, and the
other from San Augustine, New Mexico, collected by Mr. Cock-
erell ; there are some slight differences between them but both
satisfy the description sufficiently well ; the alternate elytral in-
tervals are flat, and the eyes are less approximate than in nie-
dialis.

punctate, the convex intervals sparsely punctulate and somewhat unevenly
creased, becoming subcariniform toward the sides and apex. Abdomen pol-
ished, scarcely at ail punctate, the fifth ventral with scattered punctures; legs
rather short, not strongly sculptured, the femoral tooth distinct. Length 2.8-

New Mexico (San Augustine). Mr. Coekerell.
This species is the smallest of the genus known to me, and is
allied rather closely to ovalis, being distinguishable b^' its much
narrower form, paler coloration, less punctate abdomen, relativel\^
less finely and densely sculptured pronotum and other features.
Of the three specimens before me, one has a deep and smooth
circular pit at the middle of the fifth ventral, the other two having
onlj' a shallow and feebly defined impression at the same point.
It is possible that the first may be the male, but I can dis-
cover no other differences, either in the form of the body or struc-
ture of the beak.
PARACAMPTUS n. gen.
Body narrowly oval, convex, the pronotum projecting anteriorly
and concealing the head, the met-episterna distinct ; epiraera not
visible, the suture if present concealed by the dense indument.
Head deeply inserted, the eyes small, coarsely- faceted, widely
separated and not concealed in repose, the ocular lobes feebly
developed. Beak short, parallel, narrow and nearly straight,
completely concealed in repose in a deep excavation extending
far into the mesosternum ; scrobes short, deep, lateral, attaining
the lower angle of the eyes. Antennie with the scape short, the
funicle slender, seven-jointed, the basal joint, and the second less
strongly, elongate, the seventh wider, obconical and more pubes-
cent; club oval, compressed, annulate toward apex, the basal
joint large and j)ubescent throughout. Coxae all wide!}' separated,
the posterior remote, attaining the met-episterna. Metasternum
elongate. Abdomen with the first two segments long, separated
by a fine and feebly arcuate suture ; third and fourth short, the
fifth nearly as long as the two preceding, rounded at apex, the

last three sutures straight and very coarse. Legs short, the
femora elongate, parallel and completely unarmed, the tibiae ex-
tremely short, not more than one-half as long as the femora, ter-
minated by a strong curved spur projecting sublongitudinally
from the outer angle; tarsi as long as the tibiae, the third joint
dilated and bilobed ; last joint slender; claws rather short, very
stout, simple, strongly arcuate and divergent. Elytra with the
side margins horizontally inflexed around the apices but vertical
toward base.
In general habitus this genus strongly resembles Acamptus,
but its structural characters place it in the vicinity of Lembodes ;
it is represented at present by a single species.
P. SUbtropicus n. sp. — Strongly convex, black, densely covered through-
out the body and legs with a thick grayish crust of cottony or felted consistence,
from which arise sparse subclavate scales, which are distinct on the prothorax,
but, on the elytra, very short and only distinct on the elevated intervals, the
indunient subdenuded in an elongate blackish spot behind the scutellum.
Head two-tifthsas wide as the prothorax, densely clothed with the squaniiferous
indument in a crust which continues onto the base of the beak, the latter
three-fourths as long as the prothorax, piceous, shining, nude and punctate,
parallel and slender but rapidly broadening at base. Prothorax as long as
wide, narrowed and sinuate at the sides toward apex, the latter strongly,
evenly rounded; sides becoming parallel toward base, the latter rectilinear;
disk almost even. Scutellum small, acutely elevated. Elytra one-third longer
than wide, distinctly wider than the prothorax and scarcely twice as long;
sides parallel and nearly straight, the apex broadly rounded; humeral angles
very slightly tumid; disk finely striate, not distinctly punctate, the alternate
intervals strongly elevated but nearly flat. Length 2.2-3.0 mm. ; width 0 8-
1.25 mm.
Florida (Punta Gorda). Mr, Schwarz.
The indument is usually a little darker on the prothorax, with
a fine median line and broader lateral stripe paler, and the elytra
have a transverse series of small feeble darker spots before the
middle and one or two on the suture toward apex.
Note. — It is probable that ^camjo^wsecAiwj^s, recently described
by me (Col. Not. lY, p. 445) from New York, is in reality from
Arizona, the label being erroneous.
ACALLES Schonh.
The following species belongs near huhhardi Lee, and is still
broader across the humeral tuberosities : —
838 Goleopterological Notices, VI.
A. dilatatiiN n. sp. — Stout, tlie elytra very abruptly dilated behind the
base, black throughout; pronotum with some velvety -black scales before the
luuldle and near the apex; elytra with the patches of white scales disposed
nearly as in Imhhariii, the scales of the third interval in the posterior band
more prolonged anteriorly; each of the large foveje with a broad whitish scale.
Hmd finely, strongly punctate and sciuamose, more than one-third as wide as
the prothorax, the interocular foveii extremely large and deep; beak stout,
dull, siiuamose at base, finely but strongly, not very closely punctate. Pro-
thorax slightly wider than long, strongly rounded at the sides, narrowed at
base and still more strongly toward apex, the latter one-half as wide as the
base; disk coarsely and closely punctate, the punctures coarser and more con-
fluent toward base; median carina strong at the middle, not attaining the base.
Klijini not as long as wide from above, twice as long and twice as wide as the
prothorax, the post-humerdl protuberancies extremely developed, their obliciue
anterior sides deeply emarginate midway to the base; sides strongly convergent
and rounded behind the tubercles, the apex obtuse; disk deeply perpendicular
behind in profile, having deep series of very large contiguous subtransverse
foveae, the series separated by strong tuberculiferous ridges, the humeral ridge
most pronounced. Abdomen sparsely punctate and squamose; legs densely
and unevenly clothed with scales. Length 8.0 mm. ; width 5.6 mm.
Florida. Mr. Jiilich.
The single specimen in my cabinet, which was probably taken
in the extreme southern part of the State, represents a close ally
of huhhardi, differing in the greater development of the post-
humeral tubercles and consequently much stouter form of the body,
but more particularly in the very close and roughly tuberculose
sculpture, deeper and less elongate frontal fovea and other char-
acters. The elytral fovea? are so closely crowded that they
coalesce, producing deep broad furrows between the ridge-like
intervals, while in huhhai'di the foveas are isolated and rounded.
