All taxonomic investigation, in fields touched upon in the fol-

lowing studies, must be more or less imperfect at the present stage

of knowledge of the arthropod fauna of the world. This can be

brought prominently into evidence, if we consider the usual pro-

portion of previously described species contained in any inde-

pendent collection subsequently made, in any particular group

and over the same geographic area. Although this new collec-

tion may comprise several times the number of species previously

known, it is virtually safe to say that there will be a considerable

proportion of the latter unrepresented. In this way we may be

enabled to foretell in a measure the real extent of the particular

group in any given region.

For example, the revision of the Scydmenidex, which is includ-

ed below, makes known some 175 species as inhabiting the United

States. If an independent collection were now formed, contain-

ing 175 species, it would probably include at least 75 not men-

tioned in this revision. The next independent set of 175 would

include perhaps 10 per cent. less of unknown forms, or say 68,

the next 61; then in succession 55, 50, 45, 41, 37, 33, 30, 27, 24,

22, 20, 18, 16,14, 18, 12,11, 10,.9,8, 7,6, 5 and 4, making a total

of 721, which, added to the original 175, would indicate about

896 species. This, of course, is an almost purely fanciful suppo-

sition, and yet it is possibly not so very far wide of the truth,

judging from isolated sets of species received from time to time.

There should be but little hesitation in stating that there are

within the American continent, north of Mexico, about 1,000

species of Scydmenide, 2,000 of Pselaphide, 10,000 of Staphyl-

inidze and 80,000 of the order Coleoptera. As a corollary to this

ANNALS N. Y. ACAD. Scr., [X, February, 1897.—20.

286 Coleopterological Notices, VII.

we might go further, and, in siving to the Palearctic fauna a like

number of 80,000 species, thestropics of both” hemispheres 450,-

000 species, and to Australasia and temperate South America and

Africa 90,000, state a total for the Coleoptera of the world of

700,000. Going still further, if we add to this 600,000 Hymenop-

tera, 600,000 Diptera and 900,000 of all other orders, we have as a

grand total for the Insecta of 2,800,000, which almost baffles belief,

and yet this estimate does not greatly differ from several others

which have been suggested.

There will, of course, always be argument and dispute as to

what proportion of these are really species, and what so-called

races or varieties, but this is a question which need not especially

interest us at present, in view of the perfectly arbitrary meaning

usually attached to these terms. Species,as meant in this connec-

tion, are aggregates which differ morphologically from each other

in several constant and evident structural characters, and we can

proceed by no other criterion than this in our determinations,

until life-histories and other purely biologic matters can be inves-

tigated.

To those who believe that there must necessarily be a large

amount of structural difference between species in the Insecta, |

no better object lesson could be cited than that afforded by the

genus Lachnosterna, where forms mutually so very similar as to

be formerly lumped together in almost every cabinet, were shown

some time since to have their complicated genitalia so arranged

as to even prohibit sexual union. Another equally cogent exam-

ple occurs in the genus Reichenbachia, where the species would

be mutually undistinguishable, in many cases, were it not for modi-

fications of the male antennee, so radivally divergent as to pro-

claim beyond peradventure their specific distinctness. In arrang-

ing my collection of Brazilian Barini, I have frequently been

astonished at the approximation of species in external form and

facies, there being several instances where forms are mutually

almost inseparable from a dorsal point of view, yet wholly dif-

ferent in the sculpture of the under surface or in some other

remarkable special manner.

These examples are cited in order to assist in counteracting, to

some extent, if possible, a somewhat general movement in favor

of a subdivision of biologic forms into species, races and varieties

on wholly arbitrary assumptions. No doubt, future knowledge

Coleopterological Notices, VII. , 287

will prove some of our present concepts to be correct, but when

forms differ structurally, great caution should be exercised in draw-

ing conclusions regarding the real nature or degree of relation-

ship. The movement referred to is a natural and salutary reflex

caused by the light shed by Darwin on the universality of varia-

tion and origin of species, but the variation alluded to by Darwin

is very different from that which it is often assumed to be, and

has reference solely to minute differences in definite directions due

to gradual changes in environment, not to radical and constant

divergence of form or special structure. In the opinion of the

writer there is no real distinction between species and what are

generally known as geographic races, when these differ morpho-

logically to any evident extent; species are created in this way,

and it merely becomes a question of time when divergence has

reached such a stage as to call for a special designation. As for

the term variety in its generally accepted meaning, it has no right

to exist, and is simply a burden to nomenclature.

It is impossible to express the true status of every morpholog-

ical entity; even the most isolated species are known to differ

_ greatly among themselves in the amount or nature of their adher-.

ence to a fixed type, in their individuality, or in their dynamics,

so to speak. At the present stage of knowledge it would there-

fore be the better course to recognize only species—that is, aggre-

gates of individuals, which differ constantly from each other in

well defined structure, even though intermediates known or sus-

pected may not have yet been entirely exterminated in the com-

mon border lands—and synonyms, the latter including a large

number of forms which at present come under the category of

varieties, especially those founded upon color variations, which,

in view of the rapidly increasing multiplicity of known species,

should never be dignified by name. In other words, the time has

not yet arrived for a trinomial nomenclature in the Insecta. The

employment of three words to express subspecies or varieties of

species, is not to be condemned so much from any inherent de-

fect—since we must all admit that it has certain manifest advan-

tages—as from the fact that it opens the door to names involving

more than three words. If we go beyond the essential two words

of the binomial system, there is absolutely no reason for stopping

there, and it can readily be imagined into what confusion the ex-

pression of a race of a variety of a subspecies of a species by this

288 Coleopterological Notices, VII.

means would gradually lead us; but the whims of certain authors.

admit such refinement of classification in the genus Carabus, and

perhaps others. When we know something of the true laws of

relationship it will be time enough to devise some means of ex-

pressing them, perhaps by trinomials, quadrinomials or quinque-

nomials, or perhaps by some simpler exponential method, in which:

the longest names will not stand for the most unimportant forms.

sides the sexual character relating to the anterior tarsi, which

distinguishes this genus from Amblycheila, it should be stated

that there are but two supraorbital setigerous punctures in the lat-

ter genus, while in Omus these punctures are three or four in

number. The following table embraces all the species known to-

The new forms mentioned in the table are briefly described

below. |

0. montanus.—Somewhat narrow, elongate and subparallel, deep black

and shining, Head feebly rugose, the median parts of the front nearly

smooth ; frontal impressions moderate ; labrum deeply bisinuate, the six setig-

erous punctures large and deep, the median lobe advanced and truncate ; an-

tenne 14 as long as the body, moderately stout toward base, the third and

fourth joints feebly constricted near the middle. Prothorax between 14

and +4 wider than long, rounded laterally at the apex, the sides rapidly con-

vergent and very feebly arcuate thence to the base, the latter very indistinctly

margined.and 7 as wide as the apex ; surface broadly and feebly convex,

finely and feebly vermiculato-rugose, the side margins reflexed, more deeply

at basal fifth or sixth ; median line very fine. Zlytra rather feebly convex,

elongate, evenly oblong-oval, widest at the middle, scarcely more than 14 wider

than the prothorax and 2% times as long ; sides parallel and feebly arcuate ;

punctures moderately fine, rather sparse toward the middle but denser near the

sides, feeble and scarcely closer toward apex ; foveole indistinct. Length ¢

15.5-17.5, 9 16.5-18.0 mm. ; width ¢ 5.5-6.0, 9 6.0-6.7 mm.

California (Placer Co.).

Allied to edwardsi, but narrower and more elongate, with less

convex male elytra, and with a distinctly different structure of

the labrum as indicated in the table. The description is taken

from the male, the female being a little more ventricose and with

more convex elytra.

0. Lugubris.—Moderately stout, deep black and somewhat dull through-

out. Head much narrower than the prothorax, unevenly and not strongly

rugose, the median parts of the front finely and sparsely punctate ; labrum

deeply sexpunctate, bisinuate, the advanced median lobe truncate ; antennz

fully 4 as long as the body, relatively slender, gradually attenuated as.

usual, the third and fourth joints very feebly constricted at the middle.

Prothorax relatively rather large, obtrapezoidal, the sides moderately con-

vergent and almost straight from near the extreme apex to basal fifth, thence

rapidly rounded to the base, ‘which is coarsely and rather distinctly beaded ;

side margins fine and acute; surface broadly and very feebly convex, finely

and. feebly vermiculato-rugose and dull ; median line fine, more distinet near

the base. lytra rather ventricose, oval, fully #4 wider than the prothorax

and about 214 times as long ; sides arcuate as in californicus ; punctures deep,

moderately coarse, isolated, closer and rather smaller near the sides and apex ;

foveole not well marked though visible. Length ¢ 17.6mm. ; width 6.7 mm.

California.

The two males before me are without more accurate indication

of locality and represent a distinct species between californicus

and horni. The elytra of the two specimens differ conspicuously

in form, in one having the greatest width well before the middle

and arcuately narrowing thence to the apex; in the other they

are widest at the middle, but there is apparently no other dis-

tinguishing feature. The fine side margins of the prothorax do

not perfectly attain the base, and the basal angles are extremely

obtuse.

0. punctifrons.— Moderately ventricose and rather feebly convex, deep .

black, somewhat dull. Head moderate in’ size, rather feebly rugulose, the

median parts of the front sparsely punctate ; labrum bisinuate, the median

lobe somewhat advanced and truncate ; setigerous punctures moderate in size;

antenne scarcely 14 as long as the body, rather slender and but slightly atten-

uate toward apex, the basal joint notably thicker, third and fourth joints

broadly constricted at the middle. Prothorax obtrapezoidal, 14 wider than

long, widest at apical fourth, where the sides are rounded, the latter rather

strongly convergent and very feebly but evenly arcuate thence to the basal

margin, the fine lateral margin attaining the basal bead, the latter only evident

toward the sides; surface broadly and feebly convex, flattened toward the

middle, feebly vermiculato-rugose, the rugosities rather large ; median line

very fine. LElytra 4g longer than wide, 7g wider than the prothorax and 214

times as long, widest at the middle ; surface moderately convex, coarsely and

deeply but not very closely punctate, the foveolsz not conspicuous. Length

14.5 mm.; width 5.5 mm.

California.

_ This species is allied somewhat to californicus but is smaller,

broader, more ventricose and less convex, with much feebler ru-

gulosity of the anterior parts of the body and a shorter and more

transverse prothorax. It is represented by a single female from

an unrecorded part of the State. |

0. confluens.—Rather stout and feebly convex, distinctly dull, deep

black. Head moderate in size, finely and feebly rugose ; median parts of the

front finely punctate, the impressions moderate ; labrum bisinuate, deeply

sexpunctate, the median lobe moderately advanced and truncate ; antennz

292 Coleopterological Notices, VII.

rather more than 44 as long as the body, not very stout, moderately attenu-

ated, the basal joint thick and obconic and the third and fourth joints broadly

constricted near the middle as usual. Prothorax 14 wider than long, rounded

laterally and widest at apical third, the sides thence rather strongly convergent

and feebly but evenly arcuate to the basal angles, which are slightly obtuse

but not very blunt ; lateral margin attaining the basal bead, the latter only

visible toward the sides; disk broadly and feebly convex, finely and feebly

vermiculato-rugose, the median line fine. Elytra short, scarcely 15 longer

than wide, #5 wider than the prothorax and 2%, times as long, widest at the

middle, the sides evenly arcuate ; lateral margin distinctly reflexed, more

broadly and conspicuously toward base; disk moderately convex, rather coarsely,

—closely.and subconfluently punctate, the foveole small. Length 14.0 mm.;

width 5.6mm. |

California. i | ae

The single female before me represents a species rather closely

allied to the last but differing in its shorter, more densely punc-

tured elytra and more elongate prothorax, the latter being more

broadly rounded at the sides anteriorly. From californicus it

differs in its shorter and broader form, in sculpture and in having

the lateral margins of the elytra conspicuously reflexed toward

base ; it is from an unrecorded part of the State.

O. sculptilis.—Moderately slender, strongly convex, shining and deep

black. Head moderate in size, deeply and closely vermiculate, the front

rugose throughout and not punctate; impressions moderate; labrum almost

truncate, the median lobe very broadly and evenly arcuate, the lateral sinua-

tions feebler than usual, the six setigerous punctures strong; antenne moderate,

fully 44 as long as the body, distinctly attenuate. Prothorax scarcely more

than 1, wider than long, the sides moderately convergent from apex to base

and broadly and rather evenly arcuate throughout, widest toward apex as

usual; side margins attaining the basal bead, which is traceable entirely across

the surface, as is also a line anterior to the base and another, broadly angulate,

behind the apex; basal angles obtuse but not rounded; surface strongly con-

vex, deeply and closely vermiculato-rugose throughout; median line fine but

distinct between the transverse lines. Elytra evenly suboblong-oval, widest

at the middle, fully 4 longer than wide, %¢ wider than the prothorax and 214

times as long, the sides feebly arcuate but more strongly near base and apex;

margin finely reflexed; punctures strong and not confluent; foveolz small.

Length 16.0 mm.; width 5.6 mm.

California. :

The only representative was taken by the author in the coast

regions north of San Francisco; it is amale and represents a

species allied to, and considerably resembling californicus, espe-

cially in sculpture, but differing in the rounded sides of the pro-

thorax and feebly lobed labrum.

Coleopterological Notices, VI 1 293

0. elongatus.—Elongate and but feebly ventricose, strongly convex,

shining and deep black. Head slightly narrower than the prothorax, rather

feebly rugose, the rugosities large; front not at all punctate toward the mid-

dle, the sublateral impressions rather strong and oblique; labrum strongly

bisinuate, but with the median lobe only moderately advanced, very broadly

arcuate and unevenly undulated, the punctures coarse and deep; antennz

moderate in thickness, attenuate toward tip, rather more than 44 as long as

the body. Prothorax somewhat more than !4 wider than long, the sides mod-

erately strongly convergent from apex to base and broadly, almost evenly arcu-

ate throughout, the lateral marginal line attaining the basal bead, the latter ob-

literated at the middle; ante-basal and post-apical transverse lines distinct;

disk rather strongly convex, feebly vermiculato-rugose, the median line fine.

Elytra evenly elongate-elliptical, widest at the middle, % wider than the pro-

thorax and obviously more than 24% times as long; sides evenly arcuate; re-

flexed margins fine, rather broader toward base; surface strongly convex,

moderately coarsely and deeply and rather sparsely punctate, the foveole small

but quite distinct. Length $ 16.5-17.5, 2 16.5 mm.; width ¢ 5.6-5.9,

California (near San Francisco). Mr. Dunn.

The description is drawn from the male, the female being more

ventricose as usual, with the elytra much more shouldered at base

and apparently more strongly punctured. This species differs

from lecontet in having the elytra evenly elliptical and widest at

the middle, and, from ambiguus, with which it is apparently most

closely allied, it seems to differ in its less stout antenne, less promi-

nent basal angles of the prothorax and more rounded sides of the

latter. Ambiguus is described in an entirely insufficient manner,

the few diagnostic characters given being purely comparative.

DROMOCHORUS Guér.

This genus, which was considered a connecting bond between

the Mantichorini and Cicindelini by Lacordaire, differs from Cicin-

dela, not only quite radically in facies, but in the vesti-

ture of the legs and antenne, the legs and tarsi being clothed

throughout with fine decumbent hairs and the second and third

joints of the antenne having numerous fine subdecumbent hairs

in addition to the setz, which pubescence is altogether lacking in

Cicindela. In general the structural characters are similar to

those of Cicindela, but the tibial spurs are much shorter and

the body is wingless with rounded humeri. In all the species

known to me the labrum is black with a rounded pale spot at the

middle; they may be identified as follows from the males :—

Dromochorus is peculiar to Kansas, Louisiana and Texas, pre-

sumably extending well into Mexico. Cuvcindela celeripes and

cursitans of LeConte probably constitute a distinct genus, and

are not considered at the present time.

D. sericeus.—Subcylindric, strongly convex, deep black throughout,

with a steel-blue metallic reflection only on the head behind and especially be-

neath the eyes. Head wider than the prothorax, the eyes prominent; surface

with fine and feeble longitudinal ruge, glabrous ; three labral teeth strong

and acute; antennz slender, more than 44 as long as the body, the joints:

5-11 extremely minutely and densely pubescent. Prothorax just visibly wider

than long, somewhat narrower at base than at apex, slightly constricted be-

hind the latter ; sides very feebly arcuate ; median and transversely angular

lines fine and feeble ; surface sparsely clothed with decumbent hairs on the

flanks. Scutellum triangular, wider than long. Elytra nearly twice as long as

wide, about 3 times as long as the protherax and 34 wider, widest near

apical third ; surface glabrous, granulato-reticulate. Length 11.5-13.0 mm.,

width 3.7-4.4 mm.

Texas.

The two males before me are distinctly larger than the single

female, and, in the latter, the elytra are relatively shorter.

D. pruininus.— Moderately ventricose, deep black and dull velvety in

lustre, with strong violaceous reflection throughout. Head much wider than

the prothorax, the eyes prominent ; ruge of the vertex very feeble and only

visible toward the eyes ; labral teeth moderate ; antenne slender, but little

more than 1 as long as the body. Prothorax feebly constricted near the base and

apex, the former very much the narrower ; surface dull and sculptureless, with

feeble impressed lines and lateral vestiture as in sericeus. Elytra distinctly less

than twice as long as wide, wider posteriorly, the punctures fine, feeble and

not well defined, the punctiform foveole obsolete. Length 12.0-14.0 mm.;

hind, but not relatively shorter than in the male. Three speci-

CICINDELA Linn.

While it must be admitted that the numerous species of Cicin-

dela present problems of great interest and difficulty to the tax-

onomist, it must be stated in the interests of fact, that the treat-

ment applied thus far to our representatives of the genus has been

of a very unsatisfactory kind. The paper of Mr. Schaupp (Bull.

Bk. Ent. Soc.), which is that upon which our present synonymy

rests, is superficial and betrays besides a certain lack of scien-

tific acumen at times, so that a more complete revision is almost a

matter of necessity. The fact that a considerable number of de-

scribed forms are undoubted synonyms is not sufficient reason

for the indiscriminate and unweighted lumping there applied.

Ground color is generally unimportant, but at times becomes of

value. Markings are variable as a rule, but are in many cases sur-

prisingly constant, and much careful study should consequently

be exercised in determining the relationships of allied forms, since

more or less special criteria must be applied in different parts of

the series. Sculpture is important as a rule, but has been unac-

countably disregarded by Mr. Schaupp, as, for example, in the

cases of abdominalis and scabrosa, which are distinct species and

not varietal forms of one. General form of the body, though

usually a useful specific character in this genus, has been fre-

quently neglected, as, for instance, in combining obsoleta and vul-

turina, and form and sculpture have both been overlooked in

combining sexgutata and patruela, which are abundantly distinct

species. |

In scutellaris both ground color and degree of marking are

very variable, and it is virtually certain that the varieties of this

species now recognized are truly color variations, which ought not

to have received distinctive names, especially since similar varia-

tions in ground color may appear in a large number of species.

Very different, however, is the case of purpurea and its allies,

where most of the forms united as varieties should be regarded

“ather as closely related species; two of them indeed—decemno-

296 Coleopterological Notices, VIL.

tata and splendida—are undoubtedly entirely valid as species.

Cimarrona is more elongate in bodily form than purpurea, and

is probably a distinct species, very variable within itself in ground

eolor and degree of marking. Limbalis Klug, from which limba-

lis Lec. does not differ perceptibly, is a very distinct and constant

subspecies, in which the median band reaches the margin without

the least tendency to spread longitudinally in any example known

to me. Graminea Schpp., is also a good subspecies, generally

above the average in point of size. The following are two addi-

tional subspecies of the purpurea type which do not seem to

have been alluded to hitherto :—

C. lauta.—Similar in form to purpurea, but still shorter and a little more

depressed, green, the head and prothorax with a slight coppery reflection, the

legs polished, metallic and paler green, the elytra dull, of a deep and very rich

Sericeous green with a vivid blue lateral border. Markings as in the typical

purpurea, a transverse and moderately reflexed median dash, not attaining the

sides, and a small sutural remnant of the apical lunule. Prothorax very

short and transverse, about twice as wide as long. Front sparsely punctate

and having erect blackish setz ; labial palpi black. Length 11.0-14.0 mm. ;

width 4.4—5.8 mm.

California (Siskiyou Co.).

This very beautiful form may be recognized at once by its

coloration, which appears to be quite constant, and also by its

very short and transverse prothorax. The anterior tarsi of the

male have the first three joints increasing in width, the third

quite strongly dilated and much less than twice as long as wide;

in this structural character it differs noticeably from purpurea.

C. plutonica.—Form nearly as in purpurea, but more elongate and

rather more convex ; body, legs and palpi intense black throughout ; labrum

pale, with a fine dark apical margin ; mandibles with the usual white external

dash. Head deeply concave between the eyes, the frontal convexity punctured

and more densely pubescent. Prothorax nearly as wide as the head, fully %

wider than long, nearly as in purpurea throughout. Elytra oblong, about 14

longer than wide, the intrahumeral impression at base very deep ; punctures

rather coarse but shallow, becoming sparse at base, with the subsutural series

of punctiform foves distinct. Length 13.5 mm. ; width 5.2 mm.

California (Placer Co.).

The anterior tarsi of the male have the first three joints quite

strongly dilated and somewhat increasingly so from the base, the .

third joint distinctly less than twice as longas wide. The elytra

are smooth along the lateral margins, but the only white macula-

tion is a small subsutural remnant of the apical lunule; the punc-

tures are, however, subeffaced in a transverse and feebly reflexed

line at the usual position of the pale median band of purpurea.

The following species may be placed near purpurea for the

present :

C. denverensis n. sp.—Smaller, narrower and more elongate than pur-

purea ; body pale and vivid emerald green throughout, without trace of cop-

pery reflection and with barely a trace.of. bluish tinge along the elytral mar-

gins. Head with erect white vestiture, especially dense as usual on the

frontal declivity ; labial palpi with the second joint pale ; labrum tridentate.

Prothorax less than 144 wider than long, distinctly narrower than the head ;

impressed lines deep; surface minutely and densely vermiculato-rugose ;

pubescence long and erect at the sides. lytra oblong, 14 longer than wide,

the sculpture and markings as in purpurea, except that the middle transverse

dash is reduced to a small transverse spot near the lateral margin ; apical

lunule incomplete. Length 11.0 mm. ; width 4.6 mm.

Colorado (Denver).

Abundantly distinct from the other forms which are more or

less closely related to purpurea, by its elongate outline, pale

second joint of the labial palpi and other characters. From

pusilla it differs in its entirely dark tibiz and complete absence

of any form of humeral marking. The first three joints of the

anterior male tarsi are narrowly and subequally dilated, the third

joint more than twice as long as wide.

C. depressula n. sp.—Moderately stout, somewhat depressed, feebly

shining, bright green, the head and prothorax in part with a feeble coppery

reflection ; humeral lunule generally wanting, sometimes represented by a

small spot near the basal fourth, not extending to the margin ; post-median

transverse spot slender, feebly dilated at its extremities, strongly reflexed and

attaining posterior third near the suture, not attaining the margin ; apical

lunule represented by two small detached spots. Head moderate in size, mi-

nutely strigato-rugose, the front not at all pubescent ; labrum short and trans-

verse, nearly 3 times as wide as long, imperfectly tridentate, the lateral teeth

in the form of feeble arcuations, and sometimes virtually obsolete ; antennz

slender, moderate in length ; labial palpi pale, the apical joint black. Pro-

thorax fully as wide as the head, 34 wider than long, minutely and densely ru-

gose, the impressions deep and of a dark violet blue ; pubescence sparse and

only partially erect at the sides. Elytra oblong, gradually slightly wider be-

hind, scarcely 14 longer than wide, the intrahumeral impression distinct ;

punctures coarse, deep, moderately close, nearly uniformly distributed, slightly

asperate and tinged with a cobalt reflection. Legs metallic green, the tro-

chanters black. Length 12.0-14.0 mm.; width 4.7-5.4 mm.

sculpture, smaller and more transverse prothorax, and in the form

and position of the elytral markings, the transverse reflexed line

being finer, less reflexed and more posterior in position.

C. echo n. sp.—Rather narrow and convex, dark coppery brown, the punc-

tures of the elytra blue or greenish-blue ; under surface and legs metallic

bluish-green. Head moderate in size, deeply and finely strigato-rugose and

bald ; labrum imperfectly tridentate, the lateral teeth very short and rounded ;

labial palpi pale, the third joint black ; antennz slender. Prothorax not quite

as wide as the head, %¢ to 44 wider than long, almost cylindric and only slightly

narrowed at base, the white pubescence abundant but subdecumbent on the

flanks ; impressions deep ; surface minutely but deeply rugose. Elytra dis-

tinctly wider toward apex, 44 longer than wide, coarsely, rather closely and

almost uniformly punctured ; intrahumeral impression narrow, rather deep

_ and with coarser punctures ; white maculations broad, consisting of a complete

humeral lunule, which intrudes but little upon the disk behind, a transverse

and strongly reflexed line, attaining the margin at the middle and almost at-

taining the suture behind apical third, and a complete apical lunule. Length

10.8-12.0 mm.; width 3.9-4.7 mm.

Utah (Great Salt Lake).

This species also belongs to the senilis group,and differs from

that species in its narrower form, more cylindrical prothorax,

more metallic coloring, form of the elytral markings and in the

much less dilated basal joints of the anterior male tarsi. The

male is much less stout than the female.

C. inquisitor n. sp.—Rather stout, moderately convex, feebly shining,

coppery-brown in color; elytral markings as in sperata, except’ the median re-

flexed band which is more even, less angularly reflexed and situated at a

greater distance from the end of the humeral lunule, the latter relatively much

shorter and less oblique; under surface metallic greenish, the legs coppery

green. Head broad with the eyes very prominent, feebly strigato-rugose,

finely and sparsely punctured anteriorly, the pubescence white, sparse, decum-

bent and consisting of very short and stout hairs; labrum, mandibles, palpi

and antennz nearly asin sperata. Prothorax nearly 44 wider than long, par-

allel, constricted at apex and more feebly near the base, the sides between the

constriction and the base notably protuberant; impressions rather feeble; sur-

face dull but almost smooth, minutely and feebly creased. Elytra oblong, 14

longer than wide; sides parallel and almost evenly arcuate; apex oblique, the

subapical angles prominent but obtusely rounded; surface evenly convex, the

intrahumeral impression feeble, with the feveole small; punctures moderately

coarse, finer toward the suture, nearly as in sperata and having a similar blue

color. Under surface densely pubescent toward the sides, the legs very slender.

Length 14.0 mm.; width 5.2 mm.

Texas (Austin).

The present species is allied closely to sperata but is stouter,

Coleopterological Notices, VII. 299

with a broader head, still more prominent eyes and more protu-

berant sides of the prothorax at the basalangles. The female has

the external angulation near the apex of the elytra rounded, while

in sperata this angle is acute, even inclining slightly backward at

the extreme apex. |

Of dorsalis, of which saulcy?z is evidently more than a variety,

I have before me a strongly marked subspecies from an unre-

corded locality. This has the elytra in the male more elongate,

with the punctures much coarser and denser and the dark mark-

ings fine and incomplete, the posterior arcuate dash not bent in-

ward to the suture but fine, even, very feebly arcuate and ending

at the middle of the width behind apical third; the middle longi-

tudinal dash is much less broadly hooked anteriorly, and, anterior

to this, there is only a small point of dark color in the intrahu-

meral impression. In size it is larger than the average dorsalis,

being 14.0 X 5.3 mm.in measurement. It may be named semipicta.

Of repanda, also, I have before me representatives of a sub-

species from El Paso, Texas, which may be called unyuncta. It

is smaller and narrower than repanda, as compared male to male,

with a relatively larger prothorax and smaller elytra, the white

maculation of the latter nearly similar but broader, the median

band broadly expanded at the margin, uniting with the humeral,

but not with the apical, lunule; the punctuation of the elytra is

coarser and stronger. The dimensions of the male are 10.0 X 3.8

mm. The species allied to repanda are very carelessly discrimi-

nated at present in our published lists; hzirtzcollis, for example,

is a quite distinct species, and has for a well marked geographic

race ponderosa; i12-guttata is also distinct as a species from

either repanda or hirticollis.

Willistoni is certainly distinct from fulgzda and is not a variety

as marked in the Henshaw list; it more nearly resembles lateszg-

nata. Imperfecta is a perfectly isolated species and not a variety

of cinctipennis. Several other corrections should be made in the

synonymy of Cicindela, which lack of time prohibits for the

present.

CARABID ZA.

OMOPHRON Latr.

The genus Omophron, although remarkably isolated among

its nearest relatives of the Carabidz, is composed of species

300 Coleopterological Notices, VII.

which are rather numerous, and, at the same time, comparatively

feebly differentiated among themselves; this fact becomes still

more notable when we consider the wide geographic range of the

genus. To account for these conditions we must of course as-

sume a very extensive extinction of intermediate types, requiring

considerable geologic time. In a genus whose species enjoy

wide range of environment, this lapse of time would, in nearly all

cases, bring about marked structural divergence among its com-

ponents, and the peculiar uniformity characterizing Omophron,

can be accounted for only by the universal habit of burrowing in

clean sand at the margin of water, which causes the environmental

conditions to be practically identical throughout the territorial

range. Heterocerus is another somewhat similar instance, the

environment being more varied however in this case by ample

and ready powers of flight.

Our species have been totally neglected since the revision of

them by Dr. Horn twenty-six years ago (Tr. Am. Ent. Soc., 1870,

p. 71), and, as several new forms have been since discovered, the

suggestion of a new tabular arrangement would appear to be

desirable; this is presented below :—

The new species announced above are described as follows:

0. lacustre.—Form and coloration as in americanum, except that the

surface is less convex and the subapical pale marginal spot extends forward

very obliquely nearly to apical third, the elytra rather more pointed behind

and the sides of the prothorax more divergent from apex to base. Head with

the pale area evenly angulate ; surface impunctate except in the metallic-green

basal area, which is rather strongly but not densely punctured. -Prothorax

_ Readily separable from americanum by the Heh vy flat elytral

intervals and finer and more widely separated punctures, as well

as by the maculation of the posterior parts of the elytra and the

outline of the prothorax. The description applies to the female.

0. texanum.—Broadly oval, strongly convex, rather shining, the macu-

lation nearly as in americanum, except that the posterior pale spot of the elytra

unites with the next anterior sinuous band ; dark areas with a faint metallic-

green tinge, more pronounced on the head. Head sparsely but rather strongly

punctured in the green basal area, the pale frontal spot evenly angulate and

impunctate. Prothorax short and strongly transverse, almost 244 times as |

ate throughout; coloration as in americanum; punctures sparse, irregular,

rather strong but fine, remote and feeble in a transverse median line, wanting

near the reflexed lateral margin as usual ; median line feebly impressed. Ely-

tra short, distinctly shorter than wide, finely striate, the strie moderately but

rather broadly impressed, the punctures moderate in size and quite widely

spaced ; intervals feebly convex, shining and only just visibly alutaceous.

Under surface blackish-brown, the abdomen paler ; side margins and legs pale

Texas (Austin). , |

The single female before me represents one of the allies of

americanum, but may be distinguished by its shorter and more

broadly oval form, shorter prothorax with more strongly con-

verging sides, by the finer and more widely separated punctures,

feebler strive and flatter intervals, and by some differences in the

maculation near the elytral apices. It was taken on the sandy

banks of the Colorado River in June. )

O. concinnum.—Narrowly oval, the elytra quite inflated near the base,

the sides thence rather strongly convergent and evenly arcuate to the apex,

which is somewhat narrowly rounded ; dark areas predominant, with a green

metallic lustre anteriorly, but almost completely non-metallic on the elytra.

Head with a small and acutely angulate pale frontal area, the green basal

area very finely, feebly and sparsely punctured. Prothorax but slightly more.

median band not quite attaining the sides and extending broadly to base and

apex, with its confines rather nubilate ; median impressed line rather strong.

Elytra not quite as long as wide, behind the base much wider than the prothorax,

the subbasal and post-median irregular pale bands united longitudinally near

the middle of each, isolating a rather large ante-median black area near the mar-

gin; dark sutural area feebly dilated and rhombiform near the apex ; strize not

very coarse, but broadly and deeply impressed, perfectly even and regular, the

intervals moderately convex. Under surface piceous-brown throughout, the

sides slightly more flavate ; legs pale brown. Length 4.8 mm.; width 3.0 mm.

California (Siskiyou Co.).

The description is taken from the male type, which is the only

example known to me. The species somewhat resembles gemma,

but differs in outline, in its sombre coloring, finer pronotal, but

much coarser and more regular elytral punctures, more narrowly

rounded elytral apex, and in numerous other characters.

0. solidum.—Oblong-oval, only very moderately convex, the lustre

generally rather strongly alutaceous ; dark markings with a strong but some-

-what dark metallic-green reflection. Head with a large frontal pale impunc- -

tate area which is broadly angulate posteriorly, the green basal area with nu-

merous moderate punctures. Prothorax slightly more than twice as wide as

long, the sides quite strongly arcuate, convergent anteriorly, becoming parallel

behind the middle ; punctures moderate in size, deep, rather close-set, extend-

ing to the basal angles but almost obsolete in the green transverse band, the

latter not quite attaining the side margins and only narrowly attaining the

apex on the median line, broadly attaining the base, with two approximate

pale spots at the middle, the dark areas everywhere sharply defined ; median

line fine. lytra as long as wide, the sides subparallel and but feebly arcuate,

very broadly rounded in apical third ; strise rather fine but strongly impressed,

somewhat irregular, and, to some extent, unevenly spaced, the punctures fine

Gelifernid ( Marin to Humboldt Cos.). |

This species is common in the coast regions of California, north

of San Francisco, and exists in most cabinets, but commonly con-

fused with dentatum, which it resembles in EaStHtTOH The pale

spots of the elytra are always narrower and more disintegrated,

however, than in that species, and the form of the body is more ob-

long andl parallel; the pale. frontal area of the head is limited pos:

more distantly punctured. Dentatum is more southern in its

range, San Francisco being about its northern limit.

O. semma.—Rather convex and narrowly oblong-oval, very highly pol-

ished ; dark maculation black with bright green metallic reflection, becom-

ing bluish or violet on the head, exceeding the pale areas in extent. Head

with the pale frontal area limited behind by a line which has a deep rounded

median sinus, the metallic basal area rather strongly punctate, densely so to-

ward the sides. Prothorax slightly more than twice as wide as long, the sides.

dle ; punctures distinct over the entire surface to the extreme lateral edges,

but less obvious in a small transverse area at the middle of the disk ; lateral

acute edges very fine ; dark metallic area extending almost to the sides, broadly

attaining the apex at the middle and still more broadly the base; median line

fine but strong. L£lytra almost evenly oval, as long as wide, slightly wider

than the prothorax,. the strize fine and only moderately and narrowly impressed,

the intervals but feebly convex; striae somewhat uneven, the tenth and

twelfth convergent basally, the sleveirih not attaining the base ; punctures.

The irregularity described above in the elytral stration, which

also characterizes solidum and dentatum to some extent, voles hint

with the small size, oblong form, highly polished integuments

and bright green metallic reflection, will render the identification

of this species at all times easy. I obtained a considerable series.

on the sandy banks of the Eel river, near its entrance into Hum-

varies much in this respect.

dominating and black with a feeble greenish-metallic lustre; pale areas dis-

posed nearly as in obliteratum, the head with a triangular frontal pale area; pro-

notum black, with a narrow pale lateral margin, broadly extending inward

anteriorly and narrowly and more briefly posteriorly, the median apical exten-

sion of the black area rather narrow and becoming piceous in color; pale areas.

of the elytra sharply defined, disposed nearly as in obliteratum. Head coarsely

but rather sparsely punctured in the basal metallic area; impunctate anteriorly,

the labrum more flavate. Prothorax slightly more than twice as wide as long, the

sides but feebly convergent from base to apex and feebly arcuate; median line

distinct; punctures coarse but rather sparse, extending over the entire surface

to the basal angles but wanting in an impressed marginal area in apical half

or more, and finer near the centre of the disk. Eilytra not as long as wide,

much wider than the prothorax, the humeral curvature to the basal line’ being-

tures coarse and rather close-set as a rule but somewhat variable in spacing.

legs pale brownish-flavate. Length 6.5 mm.; width 4.0-4.2 mm.

Mexico (Sonora, probably near Hermosillo). Mr. Dunn.

Differs from obliteratum in its much stronger striation, coarser

the elytra and rather shorter and stouter form. It does not ap-

pear to have been represented in the material elaborated by Mr.

0. pallidum.—Broadly oval, moderately convex, very dull and aluta-

ceous in lustre, the upper surface pale brownish-flavate in color, the head

piceous at base, slightly metallic laterally, the pale frontal spot extending

posteriorly near the eyes to their posterior limit, the intermediate dark area

bifurcate; pronotum with a transverse submetallic spot occupying median

half, with a large pale brown spot in continuation laterally nearly to the side

margins; elytra pale, with the sutureand a transverse median basal spot black-

ish and feebly metallic, the other dark areas brown and non-metallic, consisting

of a short basal line on the eighth and, ninth and another on the eleventh in-

terval, a small triangular subsutural spot at basal third, another still smaller

double spot at outer third and basal 24, and a very uneven zig-zag band at

apical third more expanded near, but not attaining, the sutural dark line.

Head rather strongly but very remotely punctate in the basal dark area. Pro-

thorax sparsely punctured throughout, the punctures becoming quite coarse

near the margins, much more than twice as wide as long, the sides rather

strongly convergent from base to apex and only just visibly arcuate; median

line moderately distinct. Elytra not quite as long as wide, distinctly wider

than the prothorax, moderately rounded externally at base, finely and feebly

striate, finely and remotely punctate, the punctures much coarser, stronger

and more close-set and the strize coarser and deeper toward the sides. Under

surface dark piceous-brown, the.abdomen paler; sides flavate; legs pale brown.

others in width and paleness of color; it partially separates the

rather coarse papilliform pubescence. The dilatation is always

feeble, and, in cordatus, becomes barely appreciable, but the

pubescent pads beneath are still evident though narrow.

The species are abundant but sometimes very closely allied

among themselves, and the systematic treatment of them offers

many obstacles to the reviewer. This has been essayed thus far

only by Dr. Horn (Trans. Am. Ent. Soc., VII), but the author in

that article assuredly exercised an undue amount of caution in

discriminating species, placing together such forms as elevatus

and unicolor, angusticollis and velutinus, and distributing a con-

siderable number of what seem to be valid species as varieties.

quite a number of hitherto unknown forms have come to light in

recent years, so that another revision of Brennus and Pemphus.

has become desirable. This is my only excuse for the present

attempt, which will undoubtedly be severely criticised in certain

quarters, because of the numerous species proposed. I would

gladly have the number less, for several reasons which it 1s not.

necessary to dwell upon, but I cannot smooth or otherwise modify

the complexity of nature, and can merely portray it imperfectly ;

to lump the various forms together in composite descriptions

would not be simplification, but rather mystification for future

reviewers. That a considerable number of species are none the

less valid in this genus, which may be compared in this respect.

with Coniontis, for being mutually distinguishable only by a

number of points not involving special disparity of structure,

but constituting marked divergence in habitus, is evidently

proved in many cases by ample series of examples.

Brennus is confined in geographic range to the true Pacific

coast faunal province, but is exceedingly abundant and wide-

ranging within those limits, constituting one of the most charac-

teristic carabid elements of the region.

The forms which I have deemed worthy of distinctive names.

are briefly diagnosed in the following table. In this table the

groups based upon the number of elytral stris are, in all proba-

bility, natural aggregates, but in many species it is difficult or

impossible to count the strie correctly, and experience will be

necessary before deciding upon the proper group in some cases.

California (near San Francisco). The male has the second and

third joints of the anterior tarsi coarsely and not very densely

squamulose beneath throughout, the first with a small terminal

pad and the fourth spinose with some longer hairs in addition,

The intercoxal plate of the mesosternum is deeply and almost

evenly concave throughout, emarginate behind. The original de-

scription of Harris, founded upon Oregon specimens, states that

the elytra have a narrow blue margin; this is not recognizable in

any individual of the present group which I have seen.

I have before me a variety of this species in which the elytral

striz, instead of being uniform, are alternately more approximate,

the broader intervals with subdisconnected series of punctures.

California (Sta. Cruz Co.).

This fine species can be distinguished at once from all others of

the cristatus group, by the unusually developed basal joint of the

antenns and peculiarities of cephalic sculpture; the papillose

tarsal pads of the male are rather dense, the fourth joint equilatero-

triangular, with the spiniform hairs long toward tip. The inter-

coxal plate of the mesosternum is flat at the bottom, with the sides

broadly reflexed. The female is more elongate than the male,

the elytra relatively wider and longer, with feebler sculpture, this

being however more confused broadly toward the sides. Numer-

ous specimens.

3. B. duplicatus n. sp.—Moderately stout and ventricose, shining, ©

deep black, without metallic reflection. Head rather wide, only moderately

elongate, the longitudinal crest beginning anteriorly in a large simple sub-

frontal ‘tubercle, expanded at the middle in a large and strongly elevated

double tubercle, and ending at the nuchal constriction in a strong and nar-

rowly rounded overhanging tubercle ; nuchal constriction very deep, its pos-

terior wall scarcely indented at the middle ; supra-orbital ridges strong, the

antennal tubercles large ; gene prominent, deeply and narrowly sinuate ; an-

tenn scarcely % as long as the body, slender, the basal joint stout and ob-

conic but rather short, not as long as the next two. Prothoraa barely as long

convex. Llytra strongly convex, almost evenly elliptical, not at all full at

base, %5 longer than wide, nearly 3 times as long as the prothorax and

2l¢ times as wide; margins very narrowly reflexed ; disk coarsely and un-

California ( Lake Co.).

; The anterior tarsi of the male are densely papillose beneath,

the pads of the first and third joints small and oval, the fourth

without pubescence but with the spines longer toward tip. The

intercoxal plate of the mesosternum is flat, with abruptly and

narrowly reflexed side margins and the usual deep posterior

emargination. The female is much larger and more ventricose

than the male, and has the prothorax a little more obviously con-

stricted near the base.

Coleopterological Notices, VII. 313

This species may be readily known among the allies of crista-

tus by the rather coarse, close, deep and uneven sculpture of the

elytra, scarcely constricted prothorax with the sides subparallel

near the base and not strongly divergent, and by the rather shorter

basal joint of the antenns. Three specimens.

Oregon. The sculpture of the head is said to recall that of cer-

tain species of Clivina, but with a more elevated carina, and the

prothorax, by its more feebly impressed lines, recedes from the

other cristate species and approaches punctatus. The male char-

acters are as in cristatus. I have seen no example of this species

and simply transcribe the diagnosis of Dr. Horn.

margins of the eyes—being more definitely tuberculiform; supra-orbital ridges

very strong but unusually short, the antennal prominences large; labrum

Northern California ?

A remarkably distinct species in the very strongly oblique and

feebly sinuate sides of the prothorax posteriorly and unusually

narrow base of the latter, rather abbreviated head, and complete

lack of any trace of the nuchal constriction which is such a.

prominent feature of cristatus, basalis and duplicatus. The inter-

coxal plate of the mesosternum is perfectly flat, with the edges

abruptly but narrowly reflexed. It should probably be placed

near rugiceps, and is represented by a single very immature

female specimen, without locality label but possibly from the re-

gion indicated above.

California (near San Francisco and Sta. Cruz). The intercoxal

plate of the mesosternum is large and irregular, transversely im-

pressed and with discontinuous side margin anteriorly, broadly

impressed along the middle and narrowly along each side poste-

riorly, emarginate behind ; there is some variation however in this

plate. Anterior tarsi of the male densely spongy-pubescent be-

neath, the pad of the first joint occupying apical half. The types

of the above outline are three males from Oakland, immediately

opposite San Francisco, and the two accompanying females are

almost similar but larger and a little more ventricose. Female

examples are before me from the peninsula of San Francisco,

which are larger, with the elytra much more elongate and nar-

rowed more toward ‘base and having the prothorax relatively

smaller and scarcely visibly wider than long. The Sta. Cruz

example also has a slightly different aspect, and I have but little

doubt that there are some closely allied species involved in the

general material which we denominate siriatopunctatus. The

strial punctures of the male are stronger than in the female as is

frequently the case. It is a common species, and large series from

carefully recorded localities would be valuable.

California (exact locality not recorded). The single female

representing this species in my cabinet cannot by any possibility

be united with strzatopunctatus, and, as it corresponds exactly

with the figure of Motschulsky, especially in the form of the

prothorax, I regard it as a very satisfactory provisional exponent

of ovalis. The sides of the mesosternal plate between the coxeze

are only very feebly elevated.

California (near Monterey).

The anterior tarsi of the male are ‘moderately dilated, with the

dense spongy-pubescent pad of the first joint occupying fully

apical half. This species differs from striatopunctatus in its shorter

elytra, smaller and less dilated prothorax, rather more impressed

A single male, taken in the same locality as decipiens, which I

have attached to that species as a variety,is remarkably different

in facies because of its wider prothorax and depressed elytra,

but so similar in other respects that it is evidently inadvisable

to announce it specifically distinct until more examples can be

examined.

California (Tejon). As an illustration of the fact, alluded to

in the introduction to the present paper, that species in the

Coleoptera which superficially resemble each other to an extreme

degree may in reality be profoundly different, the following re-

mark of Dr. Horn may be quoted: ‘* This species, and mimus of

the preceding group, resemble each other so closely that it is

hardly possible to distinguish them. In this species the hind

angles of the thorax are less decidedly rectangular, in mimus

very distinctly so.”’*

fine and strong, more elevated at the antenne, the latter setaceous, 35 as long

* There are hundreds of cases where really distinct species are unscientific-

ally bunched together in our cabinets, merely because there is no superficial

structural character apparent to distinguish them. Under patient research the

character can generally be found, and in many cases will be internal, either

affecting the genitalia or perchance the alimentary canal or other unexpected

tract, but always evincing itself by an outward peculiarity of habitus, the

force and weight of which can only be appreciated after the reviewer has made

himself intimately familiar with the subject by prolonged and attentive study.

imum width and rather: wider than the head; angles right ; disk longitudi-

nally convex anteriorly, with the impressions very feeble; reflexed side-

margins quite strong. Elytra very convex, oblong-oval, about 1s longer than

wide, barely 3 times as long as the prothorax and 24 times as wide, the. sides

very feebly arcuate except toward base and apex; disk full at the humeri,

vertical at apex in profile, having fine striz which are deeply and coarsely

impressed laterally but extremely feebly so toward the suture, the punctures

relatively coarse, somewhat uneven in size and unevenly spaced ; intervals

feebly convex laterally, wholly confused and broken up abruptly in less than

lateral fourth. Length 14.0 mm.; width 7.0 mm.

California (southern).

The densely pubescent pad of the basal joint of the anterior

male tarsus is acutely triangular and occupies rather less than

apical half. The intercoxal plate of the mesosternum is very deeply

emarginate behind and rather feebly margined along the sides.

This species is allied to punctatus, but differs in its broader pro-

thorax, with the sides parallel at base and the hind angles right.

A female from Monterey is associated with gravidus for the

present, though without doubt representing a species which may

or may not be closely allied. It has the prothorax similarly

shaped but smaller, the elytra still shorter and more evenly oval,

the striz stronger, the intervals more convex and with some sup-

plementary punctures toward tip. In the absence of the male, it

is impossible to say whether it should be placed near gravidus

or mimus. |

There is no representative of this species in the material before

me, and I have simply transcribed the description of Dr. Horn.

It is very distinct among the associates of striatopunctatus, in

the oblique sides of the prothorax, but seems to approach punc-

tatus in this respect as well as in its dull lustre.

12. B. Symmetricus n. sp.—Moderately ventricose, feebly shining,

black, the elytra with a slightly piceous tinge. Head elongate, subtriangular,

the vertex smooth; gene feebly developed, having the usual small angular notch ;

supra- orbital ridges well developed, the depression within the supra-antennal

portion deep ; antennee rather long, fully %4 as long as the body, very slender,

filiform and only just visibly thinner toward apex than at the second joint,

the first feebly thickened, much shorter than the next two, the seta at apical

fifth. Prothorax rather small, fully as long as wide, only moderately dilated

and very broadly arcuate at the sides anteriorly, rapidly narrowed posteriorly

and sinuate, the sides straight and parallel in scarcely basal sixth; base rather

more than 4g the maximum width but barely as wide as the head; angles right

and blunt ; disk but very feebly convex, the impressions slight; side margins

fine and shallow. lytra elongate and perfectly elliptical, nearly 14 longer

than wide, 2% times as long and 2% times as wide as the prothorax, the re-

flexed margins somewhat narrow ; disk very moderately convex, rather abruptly

declivous at the sides, more flattened broadly above ; strive rather fine but well

impressed, finely and obsoletely punctate, the first and second, and sixth and

seventh very irregular, the others even ; intervals moderately convex, abruptly

much confused in lateral fifth. Length 17.0 mm. ; width 7.0 mm.

California (exact locality not recorded).

The intercoxal plate of the mesosternum in the type is rather

abnormal, its thickened and elevated side margins posteriorly

being continuous with the bead of the acetabula, the anterior por-

tion, which is transversely excavated, being detached ; posteriorly

it is deeply sinuate as usual. In the unique male type the dense

pad of the first anterior tarsal joint occupies distinctly less than

apical half.

This species is quite distinct from any other in elytral form and

sculpture.

California (Sta. Barbara and Tejon). An inspection of the

type of LeConte, shows that this is a very remarkable species in

its small narrow and elongate prothorax, with unusually fine

reflexed margins, and I have no example in my cabinet which at

all approaches it. There is a decided probability that several

species were confused by Dr. Horn in drawing up the above

diagnosis.

The figure and words of Motschulsky appear to prove beyond

reasonable doubt, that he had before him this aberrant and local

species in drawing up his description of crenatus, which may be

regarded as a singular coincidence, in view of the multiplicity of

species and the apparent rarity of the one under consideration.

California (El Dorado and Sonoma Cos.). The description

refers to a single mutilated female specimen recently purchased

from Mr. Rivers. The species is remarkably distinct in its very

broad and peculiarly sculptured elytra and deeper reflexed mar-

gins of the pronotum; it is one of the largest of the genus. The

elytra are more inflated but rather less convex and more oblong

than in ventricosus.

prothorax. As the figure corresponds exactly with the examples

which are referred above to ventricosus, and, as supplementary

series of punctures are quite as evident here as in striatopunc-

tatus, I think that the synonymy now proposed may be some-

what more appropriate, although it is of course impossible to be

absolutely sure in the absence of types. |

California (near Monterey).

The ample series of ten specimens before me, represents a species:

allied somewhat to striatus but differing in its broader and much

shorter prothorax, with more strongly reflexed side margins.

The intercoxal plate of the mesosternum is generally flat, with

fine raised side margins which are interrupted at the middle and

with the usual deep posterior sinus. The female is but little

more ventricese than the above described male and has the pro-

thorax relatively a little smaller, but scarcely differs otherwise.

The pubescent pad of the first anterior tarsal joint of the male

extends through a little more than apical half.

The emargination of the gene is a very variable character, and,

in some specimens, the nick when small may be evident on one

side of the head and obliterated on the other..

pressed and quite coarsely and closely punctured, distinctly crenulating the

intervals, which are convex, without trace of supplementary punctures and

perfectly even almost to the side margins. Length 18.0 mm.; width 8.2 mm.

California (exact locality not recorded).

This species is allied to the preceding, differing in its relatively

larger, more inflated and constricted prothorax and more coarsely

but equally evenly sculptured elytra. The pubescent pad of the

first anterior tarsal joint of the male occupies barely apical: half.

The acarids infesting this genus are extremely minute, if the

numerous examples which I have seen are fully matured. One

noted on the present species is narrowly oval and barely a fourth

as long as the second anterior tarsal joint. The same species in-

fests several other widely different species of Brennus, and the

acarid is probably peculiar to this genus.

~The female differs considerably from the male above described

in the relatively larger, much more inflated elytra, which are nota-

bly fuller at the humeri, only a third wider than long, with the

sculpture less coarse and more confused at the sides; the pro-

thorax is actually slightly, and relatively very much, smaller, but

similar in form. The anterior tarsi of the male are only moder-

ately dilated, with the dense pad of the first joint occupying

more than apical half.

This is a remarkably distinct species, but appears to be allied to

mimus, differing in its somewhat smaller size, much more deeply

impressed elytral strize, narrower prothorax and other characters.

This species is distinct, among those of the present group, in

having the sides of the prothorax sinuate deeply behind and par-

allel for a considerable distance before the base as in ventricosus

head ; disk feebly convex, the impressions rather distinct; mar-

gins moderately deep and almost vertically reflexed. Elytra al-

most evenly elliptical, 2 longer than wide, 2? times as long as the

prothorax and not more than twice as wide, rather full and

strongly rounded at the humeri; reflexed margins moderate and

having coarser, widely separated punctures; disk moderately

convex, with rather fine but broadly and deeply impressed strize

bearing moderate and somewhat distant punctures, the intervals

relatively wide and only moderately convex, frequently inter-

rupted near the sides and apex but only occasionally and partially

toward the middle. Length 15.5-17.0 mm.; width 6.4-7.3 mm.

under surface of the fourth joint, but the spiniform sets are

longer and denser. The intercoxal plate of the mesosternum is

abruptly narrowed and elevated anteriorly and with the usual

deep posterior emargination. The female is larger but differs ex-

tremely little in general form, the elytra being but slightly more

inflated, though relatively much larger when compared with the

prothorax in every dimension. |

I am not certain that this is the true dissolutus of Schaum, but

it answers the description somewhat better than any other species

before me. |

27. B. sinuatus n. sp.—Rather strongly ventricose and only moderately

elongate, ‘polished ; head and prothorax very feebly alutaceous, the convex por-

tions of the latter polished ; body deep black, the pronotum near the sides and

concave elytral margins distinctly violaceous. Head moderately stout and

elongate, the vertex virtually smooth ; gene feebly developed, with the nick

small and angulate ; supra-orbital ridges fine, strong anteriorly where the

inner slope is quite gradual ; antenne scarcely % as long as the body, slender,

scarcely thicker basally, the first joint only slightly stouter, obviously shorter

than the next two, the seta fully at apical sixth. Prothoraxy relatively mod-

erate in size, as long as wide, strongly inflated, with the sides rounded an-

teriorly, strongly oblique and nearly straight thence to the subbasal sinua-

tion, becoming parallel and straight in basal fifth or sixth ; angles right ; base

1¢ the maximum width but scarcely as wide as the head ; disk feebly but dis-

tinctly convex, the impressions fine though distinct ; reflexed margins mod-

erate. Elytra subelliptical, notably full at the strongly rounded humeri and

quite pointed at apex, slightly more than !g longer than wide, about 3 times

as long as the prothorax and 2% times as wide, the reflexed margin moderate,

with coarse and widely spaced punctures ; disk rather strongly convex, with

deep and widely impressed striz which are rather coarsely but unevenly punc-

tured ; intervals convex, frequently more or less completely interrupted to-

ward the suture and very much broken up laterally, the striz readily trace-

able, however, throughout. Length 16.5-18.0 mm. ; width 6.8-8.0 mm.

California (locality unknown).

The male here described represents a species closely allied to

dissolutus, but differing in its more inflated hind body and

relatively much smaller and less anteriorly dilated prothorax,

this not differing so much in relative size in the male and female;

it also differs in having the elytral striee deeper and the intervals

more frequently interrupted throughout. The sexual characters

and mesosternal plate are nearly similar. The female is larger,

but only slightly more ventricose than the male. Three specimens.

less ventricose and less rugose elytra, and differing in the form of the pro-

thorax, which is here as long as wide and apparently a little longer, dilated

and rounded anteriorly, distinctly angulate before the middle, the sides

thence strongly oblique and sinuate to the base but not becoming parallel,

the angles a little more than right and rather blunt; base narrow, barely 14

the maximum width and about as wide as the head. Elytra elliptical, nearly

26 longer than wide, not quite 3 times as long as the prothorax and 214 times

as wide, rather full at the humeri, the sides becoming very feebly arcuate

thence to the apical obliquity; disk sculptured nearly as in sinuatus but rather

less convex, especially toward base, the intervals more even and much less

interrupted toward the suture. Length 13.5 mm.; width 5.8 mm. :

California (Hoopa Valley, Humboldt Co.).

The papille on the under surface of the anterior tarsi in the

single male before me are very coarse, and the pad of the first

joint scarcely occupies more than apical third; there do not seem

to be any papillee on the fourth joint, but, as usual, the — setae

‘are longer and more numerous.

This species is differentiated from sinuatus by a number of

characters relating to general habitus, such as smaller size, less

ventricose form, more flattened and less strongly sculptured

elytra and somewhat differently shaped prothorax; extended

series would probably prove them mutually distinct at a glance,

but having a single specimen only, I have hesitated some time be-

fore separating politus and giving it a specific status.

29. B. corpulentus n. sp.—Short, stout and strongly ventricose, black,

strongly shining, the pronotum only very slightly alutaceous, faintly viola-

ceous toward the sides, the elytra also violaceous in the reflexed lateral margin.

Head only slightly elongated, the vertex very feebly, transversely wrinkled;

gene feebly developed, with a moderately large angular notch; supra-orbital

ridges fine posteriorly; antenne slender, scarcely 3 as long as the body,

slightly thickened toward base, the first joint dilated as usual, much shorter

than the next two but longer than the third. Prothorax relatively well devel-

oped, short, much dilated and rounded anteriorly, distinctly wider than long,

the sides very strongly oblique and feebly arcuate behind the middle to the

sinuation, which is strong and abrupt, becoming straight and parallel in a

little more than basal sixth; angles right; base narrow, less.than 14 the maxi-

mum width and slightly narrower than the head; disk quite distinctly longi-

tudinally convex, the impressions distinct; lateral margins rather deep and

strongly reflexed. lytra short and broadly elliptical, rather full at the

humeri, less than 1g longer than wide, not quite 3 times as long as the pro-

thorax and but little more than twice as wide; margins rather widely reflexed

toward base and with coarser punctures; disk moderately convex, with rather

- coarse and impressed strize, becoming very coarse and irregular laterally, the

striz not very coarsely but distinctly punctured, the intervals convex, re-

motely subinterrupted, becoming narrow, irregular and more broken up later-

ally. Length 12.7-14.7 mm.; width 6.0-7.0 mm.

332 Coleopterological Notices, VII.

California (Oakland, Alameda Co.).

The description given above refers to the male, and the female

is so different that it might readily be regarded as specifically dis-

tinct; the elytra are not much broader than in the male, but are

very strongly convex, with the striz finer and more uneven and

the intervals flatter, but the prothorax is relatively very much

smaller, feebly dilated anteriorly and fully as long as wide. The

sexual characters are nearly as in the preceding species, from

which this can be readily distinguished by its short inflated hind

body. |

30. B. compositus n. sp.—Rather elongate, moderately ventricose,

black, the head and pronotum very dull, the latter without trace of bluish

lustre ; elytra polished, the concave side margins with a faint tinge of bluish ;.

body deep black throughout. Head stout and only slightly elongate, the genze

moderately developed, with a small angular notch; supra-orbital ridges

strong; eyes rather large; vertex transversely wrinkled; antenne nearly 36 as

long as the body, slender, the basal joint thicker as usual, not as long as the

next two, but very much larger than the third. Prothorax relatively rather

well developed, very slightly wider than long, dilated and broadly rounded

anteriorly, subangularly rounded at the middle; sides strongly sinuate pos-

teriorly, becoming parallel and straight in basal sixth ; angles right ; base

broad, somewhat exceeding 44 the maximum width and wider than the head ;

disk feebly convex, finely, unevenly rugulose in a generally transverse direc-

tion, the impressions distinct, the reflexed margins rather strong. Elytra

evenly elliptical, not very full and broadly, obliquely rounded at the humeri,

2¢ longer than wide, 3 times as long as the prothorax and about 2% times as

wide ; reflexed margins distinct and more coarsely punctured ; disk moderately

convex, strongly striate, the strise broadly impressed and rather coarsely but

somewhat unevenly punctured, the intervals convex, occasionally subinter-

rupted internally and much broken up broadly toward the sides. Length

17.0 mm. ; width 7.6 mm.

California (locality not recorded).

This species is quite distinct from any of the preceding in the

more opaque and rugulose and duller pronotum, with the base

relatively much wider, and in having the spongy-pubescent sole

of the first tarsal joint in the male more extended, occupying

nearly apical half. The intercoxal plate of the mesosternum is

deeply concave anteriorly, near the narrowed anterior prolonga-

tion. A single specimen.

a feeble violaceous tinge, the concave margins of the elytra more

strongly violaceous. The sides of the prothorax are oblique be-

Oregon. I have assumed that fulleri, which was attached to

marginatus as a variety, is in reality a distinct species with six-

teen elytral strive, and not fourteen, which is the condition in

marginatus and allied metallic species. It is, of course, quite

possible that my assumption in regard to the number of elytral

stris may be wrong, as Dr. Horn states that the striz in his

group “IT A” do not exceed fourteen in number. In any event,

whether classed with marginatus or dissolutus, there can be very

little doubt of the specific validity of the form under consideration.

Strongly ventricose, polished, the head and pronotum not

alutaceous ; body deep black, the pronotum with a feeble bluish

reflection, the reflexed side margins of the elytra violaceo-metallic

in lustre. Head moderately stout and elongate, nearly smooth, the

supra-orbital ridges fine posteriorly; gene feebly developed, the

notch minute and angulate; antenne fully 3 as long as the body,

slender, the basal joint but slightly stout and much shorter than

the next two. Prothorax slightly wider than long, strongly

dilated and rounded anteriorly, more narrowly rounded at the

middle, the posterior sinuation deep; sides becoming straight

terior tarsi even more feebly dilated than usual, with the papille

of the under surface rather coarse and only moderately dense, the

pad of the first joint small and apical. It agrees quite well with

the figure of Motschulsky, but is probably not a very character-

istic specimen, as the elytral intervals are almost entire. The

form figured by Motschulsky under the name ventricosus, which

is referred to this species by Dr. Horn, is certainly quite different,

but it is probable also that it does not represent ventricosus ; it

is wholly indeterminate from the figure.

33. B.cupripennis n. sp.—Elongate, feebly ventricose, shining through-

out, black, the elytra bright metallic cupreous-red, with a brilliant green

margin; legs and under surface piceous. Head moderately stout and elongate,

triangular, the genze very feebly developed and having an exceedingly small

angular nick; supra-orbital ridges very fine posteriorly, moderately strong at

the antennze, the latter slender, scarcely 34 as long as the body, with the basal

joint notably thicker and nearly as long as the next two, the seta at apical

seventh or eighth; vertex nearly smooth. Prothorax relatively rather well de-

veloped, about as long as wide, moderately dilated and rounded anteriorly,

the sides more strongly rounded well before the middle, thence oblique and

almost straight to the base, the angles much more than right and bluntly

rounded; base fully 144 the maximum width and as wide as the head; disk

feebly convex, the median line rather deeply impressed; sublateral longitudi-

nal impressions distinct, extending before the middle; reflexed margins mod-

erate. Elytra evenly elongate-elliptical, nearly 14 longer than wide, 3 times

as long as the prothorax and scarcely more than 214 times as wide, obliquely

and evenly rounded and not very full at the humeri; reflexed margins ample,

with very coarse punctures; disk evenly and moderately convex, the striz

coarse, slightly uneven, broadly impressed, deep laterally but rather shallow

toward the suture, the punctures coarse, uneven and close-set; intervals con-

vex, but slightly uneven at the sides. Femora stout. Length 15.0 mm.;

width 6.0 mm.

Washington State.

The two males before me represent a species allied to margina-

tus but slightly larger, and differing greatly from that, and all

other forms of the present group, in the thicker femora and much

more dilated anterior tarsi. The intercoxal plate of the meso-

sternum is rounded, flat, with abruptly elevated and rather fine

side margins and the usual large posterior emargination.

34. B. imsularis n. sp.—Elongate, rather feebly ventricose, shining

throughout, black throughout the body and legs, the elytra rather dusky

cupreo-violaceous, with narrow and bright ceneous side margins. Head rather

stout, moderately elongate, the vertex almost smooth, the broadly impressed

' transverse nuchal constriction rather pronounced; gene feebly developed, with

strong and inwardly inclined at the antennz, fine posteriorly; antennz slen-

der, moderate in length, the basal joint distinctly thicker, claviform, not as

long as the next two, the seta at apical eighth. Prothorax well developed,

scarcely as long as wide, moderately dilated and broadly rounded throughout

anteriorly, the sides not more strongly rounded before, but becoming gradu-

ally oblique behind, the middle, to the base, with a scarcely visible ante-basal

sinuation; angles much more than right and bluntly rounded: base wide,

more than 44 the maximum width and fully as wide as the head; disk feebly

convex, the median line strong; sublateral impressions deep, extending far

before the middle; reflexed margins rather fine. Elytra elongate-elliptical,

fully 144 longer than wide, nearly 314 times as long as the prothorax and 214

times as wide; humeri evenly and obliquely rounded; reflexed margins ample

but rather finely punctate; disk strongly, evenly convex, the striz deep and

broadly impressed, rather uneven, obscurely punctate, readily traceable

throughout the width, the intervals convex, much broken up toward the sides

and finely so toward the apex. Legs very slender. Length 17.5 mm.; width

Queen Charlotte Islands.

This fine species is founded upon a single perfect specimen,

recently sent to me by Mr. Fletcher and probably taken by Mr.

Keen. It is a female, but the species will be readilv known from

marginatus by its much larger size, more elongate and convex

elytra, larger and less posteriorly narrowed prothorax, with the

sides less sinuate toward base and several other characters.

Alaska to Oregon. The female type described above is from

Fort Wrangel, Alaska, and presumably represents the true mar-

ginatus. Other representatives differ slightly; for example, a

male from Oregon has the oblique sides of the prothorax almost

straight behind, the sublateral impressions feebler and the surface

alutaceous with violaceous reflection toward the sides. Another

female, without locality label, has a smaller and shorter prothorax,

which is duller black and without distinct indication of metallic

lustre; finally a number of specimens from Washington State are

very small, perhaps representing a geographical subspecies. The

assumed typical form has the sides of the prothorax distinctly

sinuate toward base, and the sublateral impressions very long

and strong; as is frequently the case, the prothorax of the female

is smaller than in the male.

36. B. confusus n. sp.—Elongate, feebly ventricose, shining throughout,

the pronotum not distinctly alutaceous, piceous-black, piceous beneath, the

elytra metallic seneo-cupreous in lustre, the reflexed margins brighter viridi-

geneous. Head moderately stout and elongate, the median parts of the vertex

very slightly wrinkled transversely ; supra-orbital ridges fine posteriorly ;

gene scarcely at all developed, with a very minute angulate notch ; antennz

siender, scarcely 35 as long as the body, the base joint moderately stout, about

as long as the next two, the seta at apical sixth. Prothorax relatively mod-

erate in size, scarcely as Jong as wide, moderately dilated and rounded an-

teriorly, broadly subangulate at apical 2%, the sides thence oblique and al--

most perfectly straight to the base ; angles much more than right, bluntly

rounded ; base rather wide, somewhat more than 14g the maximum width and.

fully as wide as the head ; disk feebly convex, the median line and sublateral

impressions deep, the latter sigmoid, extending to apical fourth. Elytra

elongate-elliptical, not at all full but broadly and obliquely rounded at the

humeri, nearly 144 longer than wide, not quite 3 times as long as the prothorax

and not more than twice as wide, the reflexed margins moderate in width and

coarsely, unevenly punctate ; disk evenly and moderately convex, coarsely

and irregularly punctate, the punctures arranged in vaguely defined, feebly:

impressed strizeform series, the intervals convex and much disintegrated..

Length 11.7-13.7 mm.; width 4.8-5.6 mm.

Coleopterolugical Notices, VII. 337

Locality doubtful.

The male, which is the type of the above description, represents

a species closely allied to marginatus, but differing in its Jess an-

teriorly inflated prothorax, with feebler reflexed margins and

much straighter oblique sides, more narrowly elongate-elliptical

elytra, with less impressed and very much less defined elytral

strize, in its rather smaller size, more eneous and less coppery-

red elytra and other characters. The anterior tarsi are moder-

ately dilated, with the soles very finely and extremely densely

papillose, that of the first joint small, rounded and occupying

scarcely apical third, the fourth without papille beneath; the in-

tercoxal plate of the mesosternum is deeply concave. The female

is larger, with the prothorax relatively smaller, but otherwise

similar, and the elytra but little more broadly elliptical and not

at all fuller at the humeri. The two examples before me are

without indication of locality, but were undoubtedly taken at

some point on the coast between northern California and Alaska.

California (near Monterey).

The intercoxal plate of the mesosternum seems to vary greatly

in different individuals, in the female described above being more

elongate than usual, convex and without elevated margins, while

in another specimen, which is seemingly its male, the plate is

rounded and deeply concave. The anterior tarsi of the male are

extremely feebly dilated, with the pubescent pad of the first joint

very small and apical. A female from Santa Cruz seems to indi-

cate a variety or perhaps a closely allied species, with larger elytra,

narrower base of the prothorax and more obtuse basal angles.

Although similar to the others in general organization, this

species departs remarkably in facies because of the depressed

elytra, which are more abruptly rounded at base and more gradu-

ally pointed at apex. It represents as distinct a group as mar-

ginatus, and there are possibly several closely allied forms in-

cluded at present in our cabinets.

PEMPHUS Motsch.

The species of Pemphus are much less numerous than those of

Brennus, but inhabit the same faunal regions; they are, however,

more boreal, and do not extend to the southward further than the

northern parts of California. They are distinguished by the feeble

and subeffaced sculpture of the elytra, the latter being much

more depressed toward base, narrower and elongate form of body,

longer legs, and by the spinose and not pubescent inner lobe of

the maxilla. Owing to the relatively much more elongate ab-

domen of the female, the femora extend only to the tips of the

elytra in that sex; in the male they extend far beyond the elytra.

The three species before may be readily distinguished among

themselves as follows :—

Basal joint of the anterior tarsi in the male densely pubescent beneath almost.

throughout its entire extent; prothorax widest and broadly rounded at.

the sides far before the middle; sides of the elytra reflexed and with

coarse punctures. .

Prothorax not longer than wide, the sides distinctly sinuate near the base;

elytra red-brown with polished metallic green or cupreous side margins.

In the first two species the reflexed side margins of the pro-

thorax are also occasionally feebly metallic greenish in lustre.

P. lomgipes.—Elongate, moderately ventricose; body above deep and

opaque black throughout, the legs and under surface shining and with an ex-

tremely faint violaceous lustre. Head very elongate, the vertex smooth; gen

thick, but little dilated, with a small angular notch heneath the eyes; neck

long, without trace of constriction; supra-orbital ridges fine behind, moderate

and subangulate above the antenne; eyes relatively rather small in size; an-

tennee very long, nearly *4 as long as the body, slender, feebly thickened

toward base, the first joint thicker, elongate, feebly sigmoid, 2.7 mm. in

length, much shorter than the next two; third joint 2 mm. in length. Pro-

thorax distinctly longer than wide, moderately dilated anteriorly, the sides

feebly convergent and broadly, feebly arcuate from just before the middle to

the apex, more strongly oblique and nearly straight posteriorly to basal sixth,

there sinuate and thence parallel and straight to the base; angles right and

slightly blunt; base #4 the maximum width and scarcely as wide as the head;

disk almost flat, the impressions all extremely feeble; reflexed side margins

nearly as in velutinus. Elytra, viewed perpendicularly, ?¢ longer than wide,

3 times as long as the prothorax and 2%4 times as wide, widest near apical

third, the sides thence feebly and evenly arcuate to the base, the humeri

wholly undistinguishable, disk in profile vertical behind and slightly pro-

duced at tip, very feebly convex anteriorly, not striate but with minute sub-

obsolete punctures arranged serially, with three intervals on each a little more

pronounced as usual; margin nearly flat, more coarsely but unevenly punctate,

the punctures broadly impressed and with a single series of minute, widely

separated but strongly elevated granules; minute subvertical edge finer than

that of the prothorax. Length 20.0 mm.; width 8.8 mm; length of head to

extremity of mandibles 5.7 mm.; length of hind tibia 9.5 mm.

California (Humboldt Co.).

I obtained a single male of this species near the coast ; it was

at the time walking with rather slow straddling gait on the sur-

face of a decayed log. The sides of the elytra are very oblique

before posterior third, and there is scarcely a trace of the broadly

rounded humeri of anguséticollis and velutinus.

The following species, apparently hitherto undescribed, have

been received from time to time from various sources. |

C. marginalis n. sp.—Elongate and parallel, moderately convex, deep

black, without metallic lustre except in the narrow concave elytral margins,

which are violaceous ; surface shining as in lugubris. Head less than 1 as

wide as the prothorax, feebly rugose toward the eyes but not distinctly punc- —

tate at any part ; epistomal impressions narrow but very deep ; antenna mod- _

erate, the third joint fully 3 times as long as the second. Prothorax trans-

verse, fully twice as wide as long, widest just behind the middle where the

sides are bluntly angulate, thence strongly convergent and evenly arcuate to

the apex and rather more convergent and straight to the base, meeting the

latter in an obtuse though very well marked angle, the immediate vertex of

which is prominent and acute ; base and apex equal in width, the former

broadly arcuate, feebly sinuate at each side, the middle much more advanced

posteriorly than the basal angles; disk rather feebly but evenly convex, broadly

impressed laterally toward base, the side margins defined merely by a thick re-

flexed bead ; median line fine but distinct ; surface smooth except a few fine

irregular creases and wholly impunctate. ilytra elongate, nearly twice as

long as wide, 14 wider than the prothorax, only just visibly wider at apical

third ; side margins moderately wide, becoming very fine at the humeri ; sur-

face smooth, moderately convex, with equal and wholly unimpressed series of

extremely minute and subeffaced punctures, with a few scattered coarse punc-

tures toward base, the lateral margin rather strongly and somewhat distantly

punctate and with an entire series of minute elevated granules ; three dorsal

series effaced and barely traceable. Legs moderate in length; deep black

throughout. Length 26.0 mm.; width 10.0 mm.

Arizona ?

The single male from the Levette cabinet, without locality

label, represents a species allied to lugubris, but differing in its

much narrower and more elongate form, violaceous elytral mar-

gins, relatively broader prothorax and absence of punctures on

the head. The anterior tarsi are rather strongly dilated, with

the first three joints densely pubescent beneath, and the hind

trochanters are simple.

C. spomsa n. sp.—Moderately stout, the head and prothorax very small

when compared with the elytra ; integuments deep black throughout, with-

out trace of metallic coloring at any part, the surface strongly shining and

Utah.

The male type has the anterior tarsi quite moderately dilated,

the three basal joints pubescent beneath, the pubescent pad of the

first joint transversely oval and occupying less than apical third ;

the hind trochanters and intermediate tibize are unmodified. This

species is to be plaved near peregrinator Guér. (carbonata Lec.),

but differs greatly in its small size, much smaller head and pro-

thorax, structure of the labrum and in many other details.

prothorax, deep black and devoid of metallic reflection throughout, the in-

teguments rather shining. Head %5 as wide as the prothorax, evenly and

feebly convex, not rugose but finely, evenly and rather closely punctured,

becoming smooth at apex where the lateral impressions are narrow and very

deep; labrum dilated and rounded at the sides, transverse at apex, with a

broad and very shallow median sinuation, the surface transversely impressed ;

antennze short and rather stout, only slightly longer than the head and pro-

thorax, the third joint fully 3 times as long as the second. Prothorax moder-

are not modified. Parviceps also belongs near peregrinator, and

greatly resembles the preceding species at first glance; it how-

ever differs in sculpture, structure of the labrum, in its much

deeper epistomal impressions, less transverse prothorax with less

rounded side angles, shorter and broader elytra and in several

other minor characters.

C. monticola n. sp —Ovoidal, moderately stout, rather feebly convex,

deep black throughout, without metallic lustre at any part, the surface

polished, the elytra becoming somewhat alutaceous laterally and toward apex.

angles rounded and prominent posteriorly; base transverse and slightly nar-

rower than the apex; disk very feebly convex, broadly impressed sublaterally

toward base, the sides rather narrowly explanato-reflexed, the marginal bead

Nevada (Reno).

Related rather closely to luxata, but differing in the very un-

equal elytral sculpture, less punctured head and other characters.

It belongs to the subgenus Callisthenes of Fischer.

C. arcuata n.sp.—Stout, deep black throughout, without metallic reflec-

tion at any part except a feeble trace of bluish lustre in the reflexed elytral mar-

gins. Head moderate in size, fiuely, sparsely punctate except anteriorly, and

feebly rugose, especially toward the sides, the median parts of the front, at a

short distance behind the apical margin slightly tumid, a small median im-

pression between the tumidity and apex quite distinct ; epistomal impressions

deep ; labrum subtruncate at apex, with a feeble sinuation at the middle, the

Arizona.

This distinct species of the subgenus Callisthenes is to be com-

pared only with latipennis of Horn, but differs in the female, the

only sex of either known to me, in its shorter and stouter form,

with much larger prothorax, which is broadly explanate and re--

flexed toward the basal angles, the latter being much more broadly

arcuate, in its very much more convex elytra with more arcuate

sides and more confused marginal punctuation, relatively larger

head, and in numerous other features. ,

844 Coleopterological Notices, VII.

In latipennis, the sides of the prothorax are parallel and quite

evenly arcuate throughout, and the edges of the elytra behind

the humeri are said to have a few serrations, of which there is no

trace in arcuata; at the same time, however, there is no trace of

them discoverable in the single specimen before me from Tulare

Co., California, which I have assumed to represent latipennis.

Norres. — Of calida, a species of extended distribution, I

have before me specimens which seem to represent rather well de-

fined subspecies. One of these, from Lake Superior, which I

have called stellata, is similariin form to the typical calida, but

has the elytral strize quite feeble, with the greenish-golden spots

very large and brillant and more approximate than in the normal

forms. Another, from Keokuk, Iowa, which may be named ex-

pansa, has the prothorax very large, with the sides very broadly

reflexo-explanate and distinctly greenish-metallic in lustre; the

elytra in the male are only a fourth wider than the prothorax, but

quite similar in every other respect to those of the normal forms,

except that the coppery spots are smaller. A third, from Las

Vegas, New Mexico, which may be denominated laticollis, has

the body larger, broudee and less convex than in the normal

forms, the elytra more parallel and only just visibly wider behind

the middle than at base; the antenne are deep black throughout,

and do not become pale toward apex as in the usual forms, and

the coppery spots of the elytra are obscure.

- Ina similar manner with regard to say7, I have taken specimens

at the electric lights in Norfolk, Va., which represent quite a

marked subspecies; it is narrower, with the middle tibiz of the

male less bent and the pubescent pad of the first tarsal joint en-

tire; in the larger western forms of sayz, this pad is divided

along the median line by a glabrous area. This subspecies may

be called virginica. _

A female specimen from Indiana appears to form a subspecies

of frigida, which may be named levettei. It is similar in form

and sculpture to the normal forms, but is a little more elongate,

with a smaller and less transverse See Oe which has no trace

of the concave lateral margin of frigida, the surface being even in

curvature to the reflexed marginal bead; the disk is distinctly

less than twice as wide as long. In the typical forms the surface

of the elytra has a feeble violaceous lustre, but in leveftez the en-

tire surface is deep black.

Coleopterological Notices, VII. 345

A subspecies of obsoleta, represented before me by two males

from Fort Wingate, New Mexico, and from an unrecorded locality

in Kansas, may be named microsticta; it is nearly similar in

form and size to obsoleta, but has the elytra still shorter and

broader, with the striz less impressed, the transverse lines feebler

and more approximate, with the punctures at the points of june-

ture with the striz more pronounced; there are three well marked

series of distinct though small, distant, steel-blue or violet foveolz

oneach elytron. In the form and sculpture of the head and pro-

thorax it is similar to obsoleta, but in the latter the foveole of the

elytra are all but obsolete.

Pimeliodes Walk, zimmermanni Lec. and striatula Lec., are

distinct species and should not be considered subspecies of luxata.

The first differs from the second in its larger size, broader form,

more pronounced elytral tubercles and much finer and closer

punctuation of the head and pronotum; as shown by a good

series these characters are perfectly constant. The third differs

from either of the others in its deeper striz, more irregularly

interrupted intervals and less pronounced tubercles ; the sculp-

ture of the head and pronotum are nearly as in zimmermannt.

ELAPHRUS Latr.

The following species is allied rather closely to levigatus, and

represents it in the middle coast regions of California.

E. politus n. sp.—Moderately narrow, convex, black and highly pol-

ished throughout, the legs dark rufo-piceous; head with but feeble traces of

metallic lustre at any part; depression near the basal angles of the prothorax

greenish, the foveole of the elytra with a green or violaceous metallic reflec-

tion. Head scarcely as wide as the prothorax, nearly smooth on the convexi-

ties, finely punctate in the small depressions, of which there are two arranged

longitudinally on the median line of the vertex, one, punctiform, at each side

of the neck near the eye, and the usual feeble two on the front; vertex sepa-

rated from the neck by a sensible transverse impression; labrum impressed

along the median line; antennz moderate. Prothorax slightly wider than

long, the sides strongly rounded, constricted before the base, the sides thence

divergent and straight to the basal angles, which are right and not in the least—

blunt; base broadly, evenly arcuate; disk convex, smooth, impunctate except

in the sublateral basal depression; sublateral pit before the middle feeble,

slightly punctate; impressed median line short between the vague transverse

angular impressions, which also have a few scattered punctures; under surface

minutely and densely punctured on the propleure, the hypomera impunctate.

Elytra % longer than wide, nearly twice as wide as the prothorax, slightly

widest behind the middle, smooth and impunctate, the foveole nearly as in

levigatus but smaller, feebler and less perfectly defined. Legs moderate in

length, the femora somewhat metallic greenish, the anterior tibiee and tarsi

violaceous; first four joints of the anterior male tarsi feebly dilated, Length

6.5-6.8 mm.; width 2.8-3.0 mm.

California (San Francisco).

The three specimens, which I took in the suburbs of the city,

represent a species which is smaller than levigatus,and which dif-

fers besides in its smaller head, feebler pronotal impressions with

shorter median line, and still finer and very much denser punctu-

ation of the propleure.

PROMECOGNATHUS Chaud.

The body in this genus is very smooth, highly polished and

impunctate, even the elytral strize being wholly obliterated.

There are two supra-orbital setze, and usually two anterior and

one basal seta at each side of the pronotum. Of the two de-

scribed species, crassus has the elytra much shorter and

broader than levissimus, and is a stouter insect in all its propor-

tions; the following is almost as much more slender than levisst-

mus, as the latter is narrower than crassus.

P. debilis n. sp.—Slender, moderately convex, very highly polished and

sculptureless, dark piceous-brown in color phrobebout, Head nearly as in

leevissimus, except the mandibles which are shorter, the left much less pro-

longed inwardly and less aciculate at apex. Prothorax fully 44 longer than

wide and much narrower than in lxvissimus, widest near apical third, the sides

evenly rounded, gradually convergent posteriorly, sinuate near the base, the

sides thence straight and parallel to the basal angles, which are slightly obtuse

but not in the least blunt and feebly reflexed dorsally, the impression of the

surface being quite deep. Elytra evenly elliptical, 35 longer than wide, %

wider than the prothorax and less than twiceas long ; sides broadly and evenly

arcuate. Length 9.0 mm.; width 2.8 mm.

California (Sta. Hee |

There are no well marked structural characters to distinguish

this species from either of the other two, but on comparing the

type with a very large series of /evissimus, its distinctness seems

to be apparent at once. It is only because of the completeness

of this series and the absence of any approach to the present

form, even in its smallest components, that I have deemed it ad-

visable to found a species upon the unique individual taken by

myself about ten years ago. The type bears no special evidences

of immaturity other than its paler color.

~Coleopterological Notices, VII. B47

DIPLOCHILA bBrull.

The species of Diplochila are quite limited in number and

closely resemble each other in external characters. The labrum

is deeply sinuate at the middle of the apex, with the surface

convex and unimpressed, the left mandible acute, the right

broadly truncate in a line which is longitudinal when the mandi-

bles are closed. The first three tarsal joints of the male are

somewhat excentrically dilated, and are coarsely and uniformly

squamulose beneath. The forms known to me may be thus

identified :— 3

Prothorax but slightly narrower at apex than at base; outer striz of the

elytra generally somewhat distinct; head larger, much more than 14 as

Lake Superior (Bayfield).

The smaller size of the body, still more distinct outer striz, and

wider basal angles of the prothorax, will readily distinguish this

species from impressicollis, in addition to the characters of the

table.

D. cliens.—Rather stout and quite convex, deep black throughout, the

upper surface somewhat strongly shining, the head polished. Head moderate in

size, not distinctly more than 1% as wide as the prothorax, convex, the eyes

moderately prominent and the neck scarcely constricted ; frontal impressions

rather shallow; mandibles extremely minutely and remotely punctulate toward

Kansas.

Allied somewhat to laticollis but more convex, and with more

oval and convex and much less alutaceous elytra, less prominent

eyes and less obliterated sublateral strie of the elytra; it is de-

scribed from the female. Jaéicollis occurs at Austin, Texas, in

its normal form.

ing throughout. Head small, orbicular, convex and highly polished, the eyes

moderate in size and prominence ; frontal impressions rather shallow ; palpi

the legs rather short and slender. Length 9.6 mm.; width 4.2 mm.

Florida (Lake Worth). |

The single female representing this species, by far the smallest

of the genus, was recently taken and very kindly placed in my

cabinet by Mr. F. Kinzel, of Palm Beach.

CALATHUS Bon.

The following species belongs to the gregarius division, in the

neighborhood of obscurus and behrenst.

Cc. suadalupensis n. sp.—Rather stout, elongate-oval, somewhat con-

vex, dark rufo-testaceous in color, the elytra generally a little darker ; head

feebly constricted at base, the eyes moderately convex ; antennz slender,

scarcely 14 as long as the body, the basal joint distinctly shorter than 3-6.

Prothorax scarcely 14 wider than long, the sides almost evenly and moderately

arcuate, more convergent near the apex, just visibly narrower at base than be-

hind the middle ; apex between 74 and %4 as wide as the base, broadly sinuate ;

disk feebly convex, rather broadly flattened toward the basal angles, the mar-

gins gradually less broadly reflexed thence to the apex ; basal angles rounded ;

subbasal impressions very feeble ; median line very fine, obliterated toward

base and apex. Liytra oval, moderately convex, rather less than 144 longer

than wide, nearly 4g wider than the prothorax and 2% times as long; sides

broadly and evenly arcuate; strize very fine and feeble, obsolescent toward the

sides, the intervals broad and perfectly flat; three punctures of the third inter-

val distinct and near the third stria. Under surface shining, the legs rather

long and slender. Length 11.5-12.0 mm.; width 4.7-5.0 mm.

Guadalupe Island.

This species differs from behrenst and obscurus in its much

larger size, and, from the former, also in the very much smaller

and feebler punctures of the eighth stria. It is represented in my

cabinet by a very homogeneous series of six examples.

GALERITA Fabr.

There are before me two examples which seem to represent

species not hitherto described. The members of this genus very

closely resemble each other both in form and color, but there are

certain constant differences in the vestiture, form of the head and

color of the legs, which serve amply for ‘identification. The fol-

lowing form is closely allied to janus :— |

ANNALS N. Y. ACAD. Sci., IX, March, 1897.—24.

350 . Coleopterological Notices, VII.

G. thoracica n. sp.—Rather stouter than janus, but similar in color

and vestiture. Head much longer than wide, broadly subtruncate and rounded

at base, the sides becoming nearly parallel behind the eyes; antenne long and

rather thick, the basal joints unusually long. Prothorax large, a little longer

than wide, similar in form to that of janus but more finely and densely punc-

tate and pubescent. Elytra black with scarcely a trace of violaceous reflection,

dull, % longer than wide, slightly more than twice as wide as the prothorax

and about three times as long; outline and sculpture nearly asin janus, the

pubescence a little denser. Under surface blackish, the prosternum, pro-

pleurse and legs pale throughout. Length 21.0 mm.; width 7.0 mm.

Florida. |

Differs from janus in its larger size, and especially in its much

larger and more finely and closely sculptured prothorax. The

joints of the antenne are relatively more elongate, and the first

is less narrowed at base and less clavate.

G. infirma n. sp.—Color as in californica, the body smaller and less

elongate. Head but slightly elongate, similar at base, in sculpture and in the

large rufous central spot to californica ; antennz but slightly more than 44 as

long as the body. Prothorax relatively small, but slightly wider than the

head, somewhat longer than wide, nearly similar to that of californica, but

with the sides more reflexed toward apex and less convergent and more feebly

sinuate toward base. lytra unusually short, 4g longer than wide, 2% times

as wide as the prothorax and only 3 times as long, distinctly wider behind the

middle than at base; striz quite coarse and somewhat impressed; punctures

fine and close-set. Length 14.0 mm.; width 5.0 mm.

Arizona (Yuma). Mr. Dunn.

Allied to californica, but differing very much in its shorter,

more coarsely striate elytra and smaller prothorax. The pubes-

cence is in great part rubbed off from the basal and sutural parts

of the elytra, but that which remains does not seem to be erect

as it is in californica and lecontet, which last appear to be

mutually different. This is much the smallest species of the

genus within our territorial limits, as thoracica is the largest.

There are before me two well marked geographic subspecies of

bicolor; the first, which may be called obliqua, being larger and

stouter than the normal forms, though nearly similar in other re-

spects, except that the prothorax is narrowed anteriorly from a

point more posterior; it occurs in the extreme southern parts

of Florida, the specimens in my cabinet being from Lake Worth.

The second is represented by an example somewhat smaller than

the typical forms, with relatively shorter elytra and more ab-

breviated prothorax, the latter not longer than wide, and the head

Coleopterological Notices, VII. a51

is less narrowed behind the eyes, with the tempora more rounded ;

it occurs in Towa and may be named intermedia.

SCYDM ANID.

There is undoubtedly a strong resemblance in habitus between

the Seydmeenidve and Pselaphide, but whether this similarity in-

dicates a real affinity due to community of descent, or has been

gradually brought about in widely diverging descent-stems by

reason of common habits and environments, may be a debatable

point. The principal reasons for believing that the latter may be

the case, are the entire or subentire elytra, and the purely and

exceedingly constant pentamerous tarsi in the most widely di-

vergent forms, both of these characters being completely foreign

to the Pselaphide. The truth is probably, that the Scydmenidze

have developed from staphylinid architypes, but along lines

widely diverging from the Pselaphide. The abdominal sutures

are straight, as a rule,in the Scydmenide and arcuate in the

Pselaphide, but in the tribe Eumicrini, which is distinguished

from all other scydmeenids by a large vertical pygidium and

pselaphidous hind trochanters, the abdomen cannot be distin-

guished from that of a purely typical pselaphid, the sutures be-

ing strongly arcuate.

It is not necessary to dwell at length upon the general ana-

tomical characters of the exoskeleton, as most of these will be

brought out in the tables given below, but it may be proper to

point out some of those which seem to be either peculiar to the

Scydmeenide, or prominent features of this family. The head is

borne on a constricted neck, except in the Cephenniini, which con-

stitute for this reason a very isolated tribe. In two cases,

Chevrolatia and Lophioderus, the neck is not abruptly con-

stricted, but is elongated and deeply excavated upon its dorsal

surface. The eyes are present in every species known to our

fauna, except Cephennium anophthalmicum; they are usually

rather finely faceted. The occurrence of foveze on the vertex is |

very rare in comparison with the Pselaphide, but when present

they are usually of generic import, as for example in Veraphis,

this genus being otherwise proved distinct from Eutheia by the

strong carination of the mesosternum. The mandibles are gen-

erally small, but in the European Leptomastax, become remark-

02 Coleopterological Notices, VII.

ably developed, and, in that genus, the labrum, which is small

and transverse as a rule, also becomes enormously large. The

variations of the antennze and palpi are explained in the tables of

tribes and genera.

The prothorax is an important somite in classification, especi-

ally the circular impressed foveze which are generally visible near

the basal margin, and the relative extent of the prosternum before

the coxe. The form of the elytral apices, impressions at the base

of the elytra, form of the pygidium, and form and degree of sepa-

ration of the hind coxe, are all useful taxonomic elements, but

varying in importance in different tribes. The degree of separa-

tion of the cox is, for example, much more unstable in the Eu-

connini than in the Scydmenini, the latter tribe having, as one of

its most persistent characters, the subcontiguous coxe, with a

constant narrowly cleft metasternal prolongation. The elytra

never have a trace of epipleurse, and this may be considered an

additional bond of affinity with the Pselaphide.

The side-pieces of the metasternum are rarely exposed in the

Scydmeenine, but are always distinct in the Clidicinz, where also

the hind coxee have an entirely different form. The mesosternum

is generally more or less carinate, but becomes perfectly flat in

some genera, such as EHutheia. Its parapleure are peculiarly

modified in the Scydmeenine, but in so constant a manner that

but little use can generally be made of them in classification.

The middle coxe are entirely closed by the sterna, the mes-epi-

sternum being tumid and setose and elevated above the surface

of the metasternum behind it, the epimeron, when present, forming

the obliquely sloping connecting piece, except in the remarkable

genus Ceramphis, where the conical prothorax seems to abut

directly upon the smooth and very extended metasternum.

The legs are generally rather short, the femora always more or

less clavate, the tibize simple and without terminal spurs, the ante-

rior frequently flattened within toward apex and densely clothed on

the modified surface with short stout spinuliform vestiture, this

being a highly developed feature in the Huconnini, but so con-

stant and fixed that it affords no variations of tangible weight in

classification. The claws are small, slender, divergent and sim-

ple.

The taxonomic value of the maxillary palpi of course varies

greatly in different groups of Coleoptera. In the Aleocharini of

Coleopterolugical Notices, VII. 353

the Staphylinide, a very extensive group, with structures varied

in almost every direction to an extraordinary degree, it has an

extremely fixed and constant form, while in the Omalini, the most

radical differences only serve for generic division, and,in extreme

cases of development such as Lesteva, they vary much from species

to species, in the two sexes, or even to some extent individually.

In the Pselaphide, palpal structure is also of subordinate value,

as it may vary greatly within nearly all the tribes, but in the

Scydmeenide, the structure of this organ is of great importance

because of its constancy throughout groups of genera and species,

which it is evident, for other reasons, ought to be associated to-

gether. Any decided divergence in the palpal structure is held

in this revision to have tribal weight, and is always accompanied

by other important peculiarities of structure.

Another character of vastly more importance in the present

family than in many other groups of the Coleoptera, and one

which has been singularly overlooked thus far, is the scutellum.

Even when very minute this sclerite displays an astonishing con-

stancy throughout the various genera possessing it, and, in one

case, its complete absence forms an important tribal element. It

would be as remarkable an exception for any scydmeenid having

the fourth palpal joint subulate, the neck narrow and the eyes an-

terior in position, to present the slightest vestige of a scutellum,

as it would for a harpalid beetle to exhibit a claviform anten-

na. The scutellum has been made use of extensively in the

following memoir, and will be found to be a character of consid-.

erable value.

The Scydmeenidz form an extensive family, but the species are

so small in size as a rule,and live so concealed a life, that they

are seldom collected in numbers, and, with the exception of some

six or eight species, they appear besides to be either individually

rare or local in habitat. That they are very numerous in species,

is proved by the collecting of Mr. P. Jerome Schmitt about his

home in the mountains of Pennsylvania, where, in a single isolated

region, and that not one of the best, he has succeeded in bringing

to light about 37 distinct species, belonging to some 11 genera.

All of these were placed in my hands and have given a substan-

tial advance to our knowledge of these minute animals.

The Scydmeenide are resolvably into two subfamilies by the

following characters :—

354 Coleopterological Notices, V1I.

Antenne generally distinctly clavate, usually geniculate, but with the basal

joint short or moderate in length; posterior coxze always transverse or

transversely oval; metasternum large, the abdomen short; elytra never

striato-punctate; scutellum visible or not; fourth joint of the maxillary

Palpe invariably Small ¢cces colo ss setee Odes hen oe ceeddiceeae tones SCYDMANINA

Antenne generally filiform or gradually enlarged toward tip, but without a

distinct club, strongly geniculate, with the basal joint greatly elongated;

posterior coxz small, globular, with a subconic and truncate prolonga-

tion, widely separated; metasternum short, the abdomen elongate; elytra

striato-punctate except in Mastigini, and always entire; scutellum com-

pletely obsolete; fourth palpal joint more variable in size...... CLIDICINA

These subfamilies are both represented within the limits of the

United States, but are exceedingly unequal in numerical impor-

tance, the first being abundant in genera and species, while the

second is represented by a few rare forms in the desert regions

of the extreme southwest. The Clidicine are much better repre-

sented in Europe by three remarkable genera.

of Lesteva; it cannot, therefore, be included in the table given

part of the Pacific coast fauna; the Opresini are probably repre-

sented in those regions by Scydmenus ovithorax Bndl.

LOPHIODERINI.

The very elongate neck, with peculiar dorsal sculpture, indi-

cates a marked isolation of Lophioderus from any other type of

Scydmeenidee, and in fact renders it as aberrant among the tribes

with subulate fourth palpal joint, or Scydmeenidee subulipalpi, as

Chevrolatia is among those having that joint rigidly fused to the

third ; it should therefore constitute a distinct tribal group.

LOPHIODERUS n. gen.

The head in this genus is porrect and greatly exserted, borne

upon a long, moderately constricted neck, which is carinate and

biexcavate upon its dorsal surface, the eyes median in position,

and the antennée widely separated and strongly modified in struc-

ture in the male. The maxillary palpi are of the usual type pre-

-vailing in the large tribes Euconnini and Scydmeenini, the fourth -

joint being distinct, subulate, finely acuminate and inserted ob-

liquely in the hollowed apex of the third joint. The mandibles

are unusually small, and appear to be hidden when closed under

the large declivous and conical clypeus. The prothorax is more

elongate than usual in this family, carinate at the sides pos-

teriorly and impressed transversely near the base, but without

submedian fovee, the prosternum deeply emarginate and quite

short before the coxee, with an oval pubescent foveiform excava-

tion before each.* Thescutellum is present between the bases of

the elytra, but is extremely small and somewhat elongate in form.

The elytra are entire, conjointly rounded at apex and are of the

usual structure and pronounced convexity prevailing in the Kucon-

nini.

The metasternal side-pieces are entirely covered by the elytra,

the hind coxee very wide, extending to the sides of the body and

completely. contiguous, the posterior edge of the metasternum

* The fact that this abbreviation of the prosternum before the coxe is as evi-

dent in the present type, with elongated prothorax, as is the large develop-

ment of this part in forms like Eutheia, with short and broad prothorax, shows

that the relative development of the prosternum before the coxe is a really im-

- portant tribal character, and is not due directly to the mere greater or less

elongation of the prothorax.

having a very minute circular emargination at the middle, which

is evidently a remnant of the deep fissure observable in the nar-

row produced intercoxal process in Scydmeenini. The middle

coxe are contiguous, with the acetabula apparently confluent and

bordered along their entire posterior edge with short dense pale

and scale-like pubescence. ‘The abdomen is normal and the dor-

sal pygidium not exposed. Legs generally well developed, slen-

der, with the femora noticeably clavate and the hind tarsi slender,

California. The inner arcuate outline formed by the strongly

modified joints four to six of the male antenne, reminds us

of a similar structure in Arthmius, and, in fact, the sixth joint

here is almost exactly similar to the eighth joint of the male an-

tenna of A. globicollis. This internal sinus, formed by the joints,

is probably of direct use in clasping the antenne of the female

during copulation.

the former, in the male antenne, which are radically different;

The simple antennz and absence of secondary modification,

show that the two specimens, which I took some years ago,

are both females, but the species departs widely from gracilis in

the shorter, less pubescent palpi, much more anteriorly thickened

longer lateral foveiform impressions; it also differs in the color-

stiffer bristles arise sparsely and radially on its outer slopes.

The special characters distinguishing this tribe, which is by far

the most extensive of the Scydmenide in North America, have

genera may be outlined as follows :—

EUCONNUS Thoms.

This genus, in the sense here understood, is by no means so

abundant in species in North America as in Europe, and is even

more obviously resolvable into homogeneous groups, based upon

important differences of special structure or general habitus. In

fact these groups are so isolated among themselves as to warrant

distinctive appellations, as will be noted in the table below. The

common distinguishing features of all the groups are an exserted

head, with anterior eyes and an oblong prothorax, narrowed more

or less at base and at least bifoveate near the basal margin. In

the form and structure of the head it is similar to Connophron,

but in the form and sculpture of the prothorax it is radically dif-

ferent. In the pubescence of the head and body it differs greatly

from Connophron, except in the subgenus Scopophus, which

possesses the peculiar stiff and posteriorly directed vestiture of

the occipital parts, so peculiarly distinctive of Connophron, but

the thoracic structure is still purely that of Euconnus.

As in Connophron, the antennz may have either a 4 or 3-jointed

club, and the hind coxz vary even more in degree of separation,

this being virtually fixed, however, within the limits of each sub-

genus. The elytra mutually overlap for a short transverse dis-

tance and are independently rounded at apex, as in Connophron

and other related genera, and the scutellum is wholly invisible as

usual in this part of the family.

All the subgenera appear to be equally widely distributed over

nearly the same territorial area, but no species is at present

known from the Pacific coast, and this is a somewhat remarkable

fact. But it should also be noted that the genus is more varied

structurally in the United States than in Europe, for Connophron,

Drastophus, Pycnophus and Noctophus, besides the subgenera

named below, all belong to the Huconnus type, as shown by

general constitution, and especially by elytral, cephalic and an-

tennal structure, and it is therefore probable that this type origi-

nated in North America and migrated to Europe in somewhat re-

mote geologic time by way of Greenland. Hither this, or else

there are peculiar and inexplicable reasons for the early extinction

of all species except Drastophus lzvicollis in the Pacific coast

regions, and the latter is a less likely supposition.

The species assigned below to Euconnus proper, agree satisfac-

torily with European species of the hirticollis type, except that

the hind coxse are more widely separated and the sublateral

carine of the pronotum much less developed, in fact in some

forms, such as ventralis, becoming completely obsolete; but this

is a very variable character also in the European species. Those

known to me may be recognized as follows:—

Subgenus I.

tral segments; head always much narrower than the prothorax.

black, the head becoming testaceous anteriorly ; elytra bright and pale rufous,

blackish posteriorly ; legs and antennz throughout pale rufous ; pubescence

abundant and stiff on the pronotum, sparse on the head and elytra, long, pale,

stiff and suberect on the latter. Head nearly as long as wide, the eyes rather

large and convex but not prominent, extending to their own length from the

base and evenly continuous in curvature with the sides of the occiput, which

are convergent and arcuate to the neck, the latter deeply constricted, having

the bulbiform enlargement within the prothorax minutely asperulate ; front

not visibly impressed ; clypeus even and rectilinear at apex. Antennx very

Massachusetts ; New York.

The description is taken from the male, in which sex the third and

fourth ventral segments have each two similar discal teeth, sepa-

rated by a little less than half the entire width; the teeth are short,

stout, inclined posteriorly and have their apices obliquely trun-

cate, the truncate surface black and finely and evenly rugose.

The female is very much more abundant than the male, and has the

elytra very slightly shorter, the antenne a little shorter and more

slender, with a less thickened club, and the femora perceptibly

less clavate. The posterior coxe are rather widely separated, the

metasternal edge between them broadly sinuate and acutely

prominent at the sides as usual.

Feebly ventricose, polished, impunctate, black, the elytra dark

rufous, sometimes slightly blackish toward tip; legs and antennze

dark rufous or more obscure, the latter sometimes slightly

darker toward tip; pubescence very sparse on the head and

Massachusetts, Pennsylvania, Canada (Toronto), Michigan

(Detroit) and Lake Superior. A widely diffused species but ap-

parently not very common; the bright red of the elytra mentioned

by Say is probably a character of slight immaturity, as most of

the examples before me have the elytra quite dark rufous or

piceous in color.

The male from which the description is drawn has remarkable

abdominal characters, as in the case of the allied though much

larger ventralis. The third and fourth segments have each a

posteriorly inclined short thick sublamellate discal plate, occupy-

ing about $and 4 oftheir widths, respectively, each plate broadly

sinuate throughout its width at apex and terminating laterally in

subdentiform projections, the thick apices of the plates to the

extreme lateral tips densely paved with combs of excessively

minute thick and short spinules. The female does not differ

much in general form or structure, but the femora are a trifle less.

Northern and Central Illinois. Mr. F. M. Webster.

The male, which serves as the type of the above description,

has the secondary modifications of the third and fourth segments

rather feeble, the former having two very small subapical denti-

form projections, separated by scarcely more than a tenth of the

total width, the latter with a short suberect clense comb of

spicules having the same lateral extent..and limited at each end

by a very minute corneous tooth much shorter than the spicules.

The female is a little larger and slightly more ventricose, with

rather shorter antenne, but does not differ otherwise.

4. E. varicornis n. sp.—Somewhat ventricose, polished and impunc-

tate, black, the elytra dull and translucent rufous ; legs blackish, the tarsi and

basal parts of the tibie pale ; antennse pale testaceous, the outer five joints

blackish ; pubescence sparse but coarse, pale, rather long and suberect on the

elytra, shorter and less sparse on the head, abundant and stiff on the prothorax.

Head orbicular, not quite as long as wide, the eyes moderate in size and not

prominent ; clypeus simple, with the usual short transverse sulcus at base.

Antennz moderately slender and scarcely more than ‘4 as long as the body,

the club rather strong and distinctly incrassate ; second joint about as long as

the first but thinner, feebly obconical, twice as long as wide, shorter than the

sides, widest only slightly before the middle ; humeral plica and impression

small and inconspicuous, the fovee deep; subsutural impressions entirely

Wyoming.

This species is closely allied to semzruber, but differs in its

Shorter and more strongly clavate antenne, rather broader pro-

thorax, much smaller and less conspicuous humeral plica and im-

pression, more abruptly and basally expanded sutural bead and

other structural characters. It is represented before me by a

single male.

The secondary sexual characters are nearly similar to those of

semiruber, the minute teeth of the third ventral being fully as

approximate, but the suberect comb of pale spicules of the fourth

seoment is still shorter in a transverse sense, though composed of

slightly longer spicules, these being planted along the apex of a

short projection which is emarginate in circular are throughout its

width ; in semaruber the base of the comb is the straight and un-

modified edge of the segment, the only trace of the emarginate

projection being the minute teeth which limit it laterally.

Massachusetts, Rhode Island, Michigan and Lowa (Iowa City).

The description given above applies to the male, the abdomen in

that sex being simple but with a small, deep and transversely lu-

nate impression at the middle of the sixth segment, bordering the

apical margin. The female differs scarcely at all in general form

or structure. I have found this to bean abundant species under

stones in early springtime, but LeConte states that it occurs

with Formica pennsylvanica.

If Scydmexnus bicolor Denny, (Mon. p. 68), be the species alluded

to by Schaufuss as disabling the name bicolor Leéc., it may be

stated that the former is a Scydmeenus, and is considered to bea

synonym of exilis Er., so that the name bicolor Lec. (Euconnus)

will still hold good. :

Pennsylvania (Westmoreland Co.). Mr. Schmitt.

This is one of the most interesting species of the genus and is

probably myrmecophilous. The description apples to the female,

the male antenne being nearly half.as long as the body, the

second joint much longer than the next two, three to seven no-

ticeably longer than wide, the club abrupt and parallel as in the

female but a little more elongate; the hind trochanters are trun-

cate at tip, but there are no abdominal modifications. The elytra

are more elongate, the humeral plica more distinct and the sutural

indentation rather more feeble in the male.

This species is allied closely to occultus but is slightly stouter,

and may be readily distinguished by the indented elytral suture ;

the erect sete of the elytra are much less conspicuous.

7. E. occultus n. sp.—Somewhat narrow and feebly ventricose, polished,

the elytra minutely, sparsely and feebly punctulate, pale rufo-testaceous

sparse and erect sete, the hairs rather short and recurved, coarse on the flanks,

finer and shorter toward the suture, toward which they are obliquely directed

behind the middle, abundant, short, coarse and stiff on the head and prono-

tum. Head wider than long, broadly rounded at base, the sides subparallel

and rounded behind the eyes, which are small but convex and prominent ;

antennal prominences convex and distinct; clypeus transversely truncate,

No marks indicative of sex can be discovered in the two speci-

mens before me, but in the eastern specimen the two penultimate

antennal joints are more transverse, and the seventh joint is per-

fectly similar to the sixth and just visibly larger. This species

is said to occur with ants.

8. E. migrescems n. sp.—Rather narrow and feebly ventricose, black

throughout, the abdomen pale at. apex; legs and antenne testaceous; Jntegu-

New York (Hudson Valley). Mr. H. H. Smith.

There are no means of directly determining the sex of the

unique type, the external characters in the present subgenus be-

ing extremely feeble, but, from analogy with affinzs in the pubes-

cence of the elytra, itis a female. The species may be readily

known from any of those which precede by its black color, with

pale legs and antenne, and it may also be distinguished by the

punctate elytra.

Pennsylvania (Westmoreland Co.). Mr. Schmitt.

The male serves as the type of description, and the female has

the elytral pubescence much less abnormal and almost uniform

throughout, being sparser toward the middle posteriorly than in

the male, but scarcely differs in any other particular.

The tip of the copulatory spicule in the male is slender, thin,

parallel, with the tip obtuse, but produced in the middle in a

minute rounded lobe, the lateral lobes each with a slender, seti-

form and unusually elongate appendage, extending much beyond

the tip of the corneous median portion. The first four joints of

the hind tarsi are almost exactly equal among themselves.

This species is closely allied to nigrescens, but differs in its

much narrower prothorax and relatively larger head, somewhat

narrower form of the body and more oval and more basally nar-

rowed elytra. It is represented by a large and homogeneous

series. |

on the head, unusually short, closely recurved, very even and completely de-

void of intermingled erect setze on the elytra. Head rather well developed,

not quite as long as wide, subcircularly rounded behind the eyes, which are

only moderate in size but rather convex and prominent ; antennal prominences

moderate, the excavations very narrowly separated on the declivous front ;

clypeus normal, rectilinearly truncate at apex. Antennx short, as long as the

head and prothorax, moderately stout, the club strong, parallel and very abrupt

sions rather short and narrow but deep; suture finely beaded, the bead

trianguiarly expanded at base. Legs moderate in length, the femora distinctly

clavate. Length 1.0 mm. ; width 0.38 mm.

North Carolina (Asheville).

The single type before me is a male, the cedeagus being barely

protruded; its narrowed apical portion is subparallel, bluntly

rounded at tip, thin and with its plane turned strongly upward

toward tip in profile; the lateral appendages are well developed

and finely setose at apex.

This small but distinct species may be readily distinguished by

the isolated foveee of the pronotum, distinct humeral plica, short,

recurved and even elytral pubescence, strong and abrupt antennal

club and other characters. :

Texas (Colorado River).

This species is very distinct from any other of this peculiar

group in the elongate-oval and narrow form of the head, form of

the pronotum and in many other structural features. The sex of

the unique type is not determinable.

Texas (Colorado. River).

378 Coleopterological Notices, VII.

A small species, somewhat allied to gratus but differing in the

less abruptly formed antennal club, deep impression joining the

pronotal foveze, smaller head and much longer and more bristling

elytral vestiture. From putus it differs greatly in its narrower and

less apically narrowed prothorax, much broader head and in other

features of structure and facies. The single type in my cabinet

is of undetermined sex.

The single type is probably a male, as there appears to be a

narrowly obtuse corneous apex of the copulatory spicule visible

at the tip of the abdomen, but there are no secondary abdominal

or crural modifications. .

Although the hind coxz are very narrowly separated, this

species differs very greatly from the others of the present sub-

genus in its long and erect elytral vestiture, antennal structure,

pronotal impressions, punctate elytra, tarsal structure and many

other characters.

New York, Pennsylvania, Tennessee, Illinois and Iowa. A

very common and rather widely diffused species in swampy places.

The above description applies to the male, but the female differs

only slightly, having the antenne a little shorter but at the same

time more slender throughout, with a less elongate and a less

conspicuous club. There are no secondary sexual characters on

the surface of the abdomen, the latter being black with the last two

segments testaceous. The hind coxe are well separated, the pos-

terior tarsi filiform, with the first three joints equal, the fourth a

little shorter, and the claws rather long, slender and strongly

arcuate. |

This species forms an isolated subgenus of Euconnus, distin-

guished by the form of the clypeus, glabrous head and elytra,

entirely obsolete humeral plica and impression, unbeaded suture,

3-jointed antennal club, peculiarities of pronotal sculpture and

other characters. |

Rhode Island (Boston Neck). _

This species is allied quite closely to fatuus, as indeed are all

the species of this subgenus, but may be distinguished at once by

the strongly inflated hind body, much paler antennal club, slightly

larger head and other structural characters. Sexual marks are

not discernable in the four specimens before me.

Massachusetts and New York. A minute species, which can

be readily identified by the characters given above. The abdomen

is pale at apex as usual, and I can perceive no indications of

sexual identity.

I have attached to this species for the present, as varietal

forms, a large series from Ottawa, Canada, which differs from the

typical form in its deep black color and. stouter antenns, with

much stouter club, and two specimens from. Illinois, which are

decidedly larger, black in color and with stouter antenne.

Texas (Galveston).

The two specimens, which I took some years ago, represent a

species allied to fatuus and hedillus, but distinguishable from the

former by the shorter and more inflated elytra, smaller head with

larger and more prominent eyes, still more slender antenne with

paler club and transverse eighth joint, and from the latter by its

This species is also closely allied to fatuus, but differs in

numerous structural characters, among which may be mentioned

the shorter and smaller, though rather more inflated elytra, much

This species, though evidently allied closely to fatuus, differs

obviously in its much stouter antennal club, the latter differing

further from any other of this section, in being much paler, in-

stead of darker, than the remainder. Sexual characters are not

observable, but in the type the anterior tibizee are turned inward

slightly at tip.

In the type specimen the right elytron is removed, and, by

lateral sight, the inner edge of the left is observed to have a ver-

tical inner keel under the subbasal bead, and immediately behind

this a grooved and rather complex locking fold of the edge. The

dorsal pygidium covered by the elytra is very large, strongly con-

vex and is feebly punctulate and sparsely pubescent toward tip.

Besides the above forms which are deemed worthy of descrip-

tion, there is before me another example, from Florida, which

seems to represent a distinct species, but as it appears to be

immature and is closely allied to some others, it is best not to

name it at present. Indeed all of these six forms of Psomophus

might readily be regarded as strongly marked geographical sub-

species of one type, but the structural differences are so radical

and obvious, that it becomes a matter of necessity to name them,

in order that they may be subsequently referred to.

PYCNOPHUS np. gen.

The species described by LeConte under the name Scydmenus

rasus, presents numerous structural peculiarities which declare

its isolation from every other known type of the Euconnini. In

habits also it is more purely myrmecophilous than most other

North American species of the tribe, though even here we may

have cause to doubt the completeness of the symbiosis.

The head is large and truncate at base, but is borne on a

strongly constricted and exserted neck, the antennal cavities

widely separated on the declivous front, with the intermediate

surface not modified, the clypeus short but abruptly subporrect,

so that there is a strong reéntrant angle in profile between

the front and plane of the clypeus, the apex of the latter even.

Labrum large, transverse. Mandibles relatively very small, the

maxillz and palpi more than usually developed, the second joint.

of the maxillary palpi slender, moderately clavate and slightly

bent at apex, the third long, rather abruptly and strongly clavate

in apical half, the basal half forming a long and very slender

peduncle; fourth joint slender and aciculate. In most of its re-

maining characters the single known species might be regarded

as an aberrant Euconnus; it may be described as follows :—

1. P. rasus Lec.—Proc. Acad. Nat. Sci., Phila., 1852, p. 153 (Seyd-

mzenus). a

Stout, polished and impunctate, pale rufo-testaceous through-

out; body completely glabrous, with the exceptions noted below.

Head large, subquadrangular, much wider than long, glabrous,

except a brush of dense coarse pale hairs at each side of the basal

surface of the occiput near the neck, the latter ? as wide as the

head; eyes small, rounded, anterior and not prominent. An-

tennee rather thick, with a somewhat abrupt and moniliform 4-

jointed club, nearly $ as long as the body; joints two to seven

cylindric and very closely connected, the second a little thicker

and slightly elongate; three to six equal in width; third, fourth

and sixth subequal and not quite as long as wide; fifth rather

longer than wide; seventh but just visibly wider, feebly obconic

and a little longer than wide; joints of club much more loosely

connected ; eighth 2 wider than the seventh, oval and a little

longer than wide; ninth and tenth 4 wider, a little wider than

long, narrowed apically, the apex narrowly truncate; eleventh

rather thicker, very obtusely ogival and slightly oblique at apex,

much shorter than the two preceding. Prothorax rather small,

about as long as wide, not quite as wide as the head ; sides paral-

lel in basal half, convergent apically; surface completely glabrous

except a few short hairs on the flanks anteriorly near the head,

Coleopterological Notices, VII. 387

the apical margin at the sides broadly lobed; disk with two small

and very widely separated foveze near the basal margin but not

otherwise modified. Elytra large, oval, somewhat less than three

times as long as the prothorax and twice as wide; sides sub-

parallel, broadly, evenly arcuate; humeral plica broad and indefi-

nite, the subhumeral impression large but feeble; foves deep,

perforate and approximate; suture not beaded, the impressions

obsolete. Mesosternum finely and strongly carinate. Meta-

sternum large and long. Hind cox rather narrowly separated:

Legs stout and well developed ; two anterior femora strongly, the

other four moderately, clavate; hind tarsi cylindric, the joints

compactly joined, the first four equal in length; ungues slender

and moderately arcuate. Length 1.65-1.9 mm.; width 0.7-0.85

mm.

Canada (Ottawa), New York, Pennsylvania and Iowa (Iowa

City). A rather common species and more than usually variable

in point of size. The parapleuree of the mesosternum are tumid,

as usual, and have a few sparse hairs. The above description is

drawn from the female, but sexual differences are not obvious in

the series before me, and the male has no striking secondary

characters.

_ It appears to be certain that the Huconnus calvus of Sharp, re-

cently described in the “ Biologia ” from Guatemala, is not only a

member of this genus, but that it is exceedingly closely allied to

T asus.

NOCTOPHUS »n. gen.

This name is proposed fora large species, densely pubescent

throughout, having in general the structural characters of Kucon-

nus, but exhibiting differences in antennal, labral and crural

features which seem to demand a generic separation. The head

is large, the antennal cavities widely separated by the simple de-

clivous front, the clypeus simple and rectilinearly truncate, its

plane of inclination nearly the same as the front, from which it is

separated by a feeble transverse depression joining the cavities.

Labrum large and transverse, its anterior margin very deeply

sinuate at the middle. Mandibles and eyes well developed.

Palpi missing in the type. Antenne moderate in length, with a

clearly defined 5-jointed club.

The prothorax is nearly as in Euconnus but without trace of

388 Coleopterological Notices, VIL,

caring, merely having in a common transverse line near the base,

a fovea at each side at the summit of the flank, and three, clearly

defined, toward the middle of the disk, not united by a transverse

impression. The elytra overlap and are individually rounded

at apex as in Euconnus, but leave exposed a declivous dorsal

pygidium of small extent. The prosternum is deeply emarginate

before the coxe, and the mesosterum strongly carinate, as in all the

other genera of this tribe. The hind coxe are almost completely

contiguous. Legs well developed, the femora all extremely

clavate, the tibiee thickened and densely pubescent but narrowed

at base, the tarsi filiform and slightly compressed, the first four

joints of the posterior decreasing very slightly and uniformly in

length. The hind coxe extend to the extreme sides of the body,

and the met-episterna are not in the least exposed.

The species may be described as follows :—

1. N. schmitti n. sp.—Moderately stout, polished, subimpunctate; an-

terior parts and antennz dark rufo-piceous, the elytra and legs paler, dark

rufo-testaceous; pubescence very abundant, coarse, pale in color, bristling

densely backward from the occiput, short and not very conspicuous on the

prothorax, close-set, even, moderate in length and distinctly recurved on the

elytra. Head transversly oval, the base broadly rounded; eyes moderately

large, subanterior, somewhat convex, much wider than long and composed of

large, well developed and very convex contiguous lenses. <Antennz stout, not

quite 44 as long as the body; second joint shorter and very much thinner

than the first, only slightly thicker than the following, feebly obconic, much

shorter than the next two and 4 longer than wide; three and four equal,

cylindric, just visibly longer than wide; fifth a little wider, quadrate; sixth

still a little wider, more obviously beaded at base, slightly wider than long,

_ conic at apex; seventh abruptly %§ wider, very nearly as long as wide; eight

to ten perfectly similar to the seventh, but just visibly wider and successively

slightely more transverse; joints seven to ten strongly conic at apex; outer

five transversely truncate and strongly beaded at base; eleventh slightly

thicker, ogival but not oblique at tip, not quite as long as the two preceding.

Prothoraz rather large, nearly as long as wide, 44 wider than the head,

rounded at the sides anteriorly, broadly constricted toward base, nar-

rowed toward apex, the latter truncate and %4 as wide as the base. lytra

elongate-oval, nearly 44 longer than wide, almost 244 times longer than the

prothorax and barely % wider, broadly, evenly arcuate at:the sides, rather

obtuse at apex; humeral plica rather long, the subhumeral impression large

and conspicuous, gradually evanescent; foveze distinct, not very approximate,

the inner the stronger; subsutural impressions rather strong, the suture feebly

elevated but not definitely beaded toward base. Abdomen very densely pubes-

cent, dark brown, the last two segments pale. Length 2.1 mm.; width

0.78 mm.

Coleopterological Notices, VII. 389

North Carolina. Mr. Schmitt.

The type appears to be a female from the aspect of the opening

between the dorsal and ventral plates at the apex of the abdomen.

It is probable that the Scydmenus crassicornis of Schaum,

(Anal. Ent., 1841, p. 23), from Colombia, also belongs to this

genus. |

DRASTOPHUS n. gen.

The sole representative of Euconnus thus far discovered in the

Pacific coast faunal region, is of a distinct and pronounced type

in having the prothorax strongly and subglobularly convex, with

a minute and feeble double fovea bordered inwardly by a very

small carina at each side, at the basal margin, but without further

modification of any kind, the median fovez and transverse im-

pression being wholly obsolete ; there is, in fact, not the feeblest

trace of a character which is peculiarly constant and distinctive

of Euconnus in all its eastern representatives. Otherwise, how-

ever, there is no structural feature which would prohibit us from

associating levicollis with Euconnus as a subgenus.

The typical representative of the genus may be described as

follows from the male :—

1. D. Leevicollis n. sp.—Rather strongly ventricose, polished, impunctate,

uniformly blackish-piceous in color, the head pale, the legs and antennz pale

flavo-testaceous throughout ; last two segments of the abdomen paler ; pubes-

cence moderately abundant, sparse on the head, short, coarse, erect and bristling

on the prothorax, moderate in length, recurved and intermingled with longer

sparse and more erect setz on the elytra. Head moderately developed, very

slightly wider than long, broadly subparabolic behind the eyes, which are very

anterior in position, rather small and not prominent ; front feebly swollen

between the antennal cavities and separated from the clypeus by a feeble trans-

verse groove, the clypeus simple, subporrect, rectilinearly truncate at apex ;

labrum well developed, almost circularly rounded, apparently very obsoletely

sinuate at the middle of the apex ; palpi normal. Antenne moderately long,

fully 144 as long as the body, somewhat slender; club pronounced though not

robust, rather well differentiated ; second joint nearly as long as the first but

slightly narrower, obconic, 4 longer than wide, barely as long as the next

two but distinctly thicker ; three to six equal in width, cylindric ; third 1s,

and fifth 14 longer than wide; fourth scarcely visibly elongate ; sixth dis-

tinctly shorter than wide; seventh /4 wider, subglobular, as long as wide;

eighth 1g wider than the seventh, rounded, not quite as long as wide ; ninth

wider ; last three increasing very slightly and gradually in thickness among

themselves; ninth 14, tenth #4 wider than long ; eleventh large, as long as the

two preceding, gradually and acutely pointed but only slightly oblique at apex.

390 Coleopterological Notices, VII.

Prothorax subglobular, scarcely as long as wide, nearly 14 wider than the head,

truncate at apex, strongly rounded at the sides, narrowed at base, the surface

strongly and evenly convex. Llytra nearly % longer than wide, 244 times

longer than the prothorax and 5 wider, strongly inflated near the middle and

very much narrowed thence to the base; apex narrowly rounded; humeral

plica and impression obsolete ; fovez large, deep, equal, perforate and approxi-

mate, the inner slightly emarginating the sutural bead ; subsutural impres-

sions obsolete, the suture feebly beaded and only very near the base, the bead

rapidly and triangularly expanded at base. Legs well developed, the femora

moderately clavate, the anterior more strongly; hind tarsi filiform, the first

three joints subequal and slightly elongate, the fourth distinctly shorter; hind

coxee only moderately separated, the distance being equal to about 14 of their

individual width. Mesosternum strongly carinate. Length 1.25mm.; width

0.45 mm.

California (San Francisco); British Columbia.

The male has the abdomen simple, with the exception of the

fifth segment, which has on the disk near the apex two small and

feeble wart-like elevations, mutually separated by about 4 of the

width of the segment. The female does not differ appreciably

from the male. The pubescence of the head is sparse and irregu-

lar in arrangement, except at the sides on the tempora, where it

is coarse, abundant and directed posteriorly. This species is

abundant throughout the Pacific coast districts.

CONNOPHRON n. gen.

The species separated under this name constitute by far the

largest and most characteristically American element of the

family, and the European fauna does not appear to possess any

types which can be associated with them, either in structure or

general facies. We in fact have here an example of the non-con-

formity frequently observable between the faunas of Europe and

eastern North America, as evidenced further in the genera Meli-

gethes, Bythinus, Tenebrioides, Otiorhynchus, Hymenorus and

numerous other instances, where large genera are confined prin-

cipally to one continent, although represented also in the other.

Connophron does not appear to extend into the true Pacific coast

fauna, which fact might rather have been anticipated than other-

wise, in consideration of its purely American origin ; it however

penetrates very nearly to that limit, being found in southern Cali-

fornia and eastern Oregon.

In general structure Connophron is closely allied to Euconnus,

but differs in its conical prothorax, devoid of basal foves, this

Coleopterological Notices, VII. 391

apparently constituting a differential feature of true generic weight

which appears to have been overlooked. The pronotum is low-

ever frequently impressed transversely near the base, the impres-

sion generally distinctly interrupted at the middle, but there is

in no case\even so much as a trace of the circular pits so charac-

teristic of Euconnus. :

The body is generally somewhat stout and noticeablv ventri-

cose, much more so as a rule than in Euconnus, and there are but

few exceptions—such as clavatum—where the form becomes

slender, though always remaining strongly convex. The head is

moderate in size, convex, without asexual irregularity of any

kind except in the extremely minute caviceps, strongly rounded

behind, the occiput descending abruptly and almost vertically in

profile to the neck, which is constricted as usual. The eyes are

quite anterior in position and vary greatly in size and promi-

nence. The antenne vary but little in type of structure, and are

not affected sexually to more than a slight degree, the two basal

joints larger, the next four cylindric and equal in width, forming

a peduncle for the enlarged apical parts, the seventh forming a

transition to the more or less elongate 4-jointed club, which, how-

ever, becomes purely 3-jointed in a few species, the eighth joint

then being nearly similar to the seventh; but the eighth varies

considerably in size in the 4-jointed club, so that the 3-jointed

condition is simply an extreme limit, and the species possessing

it do not present any other differential feature. The species hav-

ing a 3-jointed club in Euconnus constitute much more abruptly

circumscribed groups. The maxillary palpi have the third joint

elongate and obconic or suboval, the fourth small, slender and

aciculate. |

The hind coxe are rather narrowly separated, in one group be-

coming almost contiguous and with the abdominal process angu-

late; in these species the first ventral segment is peculiarly modified,

the posterior tarsi longer, with the joints more unequal and the

hind tibiz provided at apex with a long and slender spur in the

male. This singular spur is, however, not confined to the group

with triangular intercoxal process, but occurs also in some of the

minute species with simple clypeus assigned. to the preceding

section. The clypeal tooth so prominent in the larger species of

the first group, having an unimpressed pronotum, is a perfectly

asexual feature, and seems to be constant in form and size in all

392 Coleopterological Notices, VII.

the individuals of the respective species, wherever an opportunity

has occurred to inspect a series of examples. The elytra are

separately rounded at apex and mutually overlap for a consider-

able distance, the fine raised line indicating the limit of overlap

diverging on each from the inner edge posteriorly. The hind

wings are fringed with stiff erect hairs. There is a terminal

dorsal pygidium which is entirely concealed by the elytra. The

integuments are always rather plentifully clothed with hair, which

is simple in structure on the elytra, but intermingled with shorter

and stiffer spicules on the anterior parts; it is directed backward

on the head and densely clothes the basal parts; there is also a

short erect and oblique fringe at each side of the occiput.

The sexual characters are very feeble as a rule, but in the very

minute biceps, and, to a less degree, in caviceps, become extremely

pronounced, the head in the male being modified to as great a

degree as in Batrisus. In fronéale and its immediate allies there

is a small pubescent area between the antennal prominences which

is wanting in the female, but beside these cases I have noticed no

sexual modification in any part of the bodv, except occasionally

a very slight one in general form. The terminal spur of the hind

tibiee in the males of a large section of the genus, is a character

altogether peculiar to Connophron. The form of the cdeagus is

noticed under the descriptions of those species in which it hap-

pened to be visible in the particular representative studied, but

the organ is seldom protruded in mounted specimens.

The species are exceedingly numerous and those which I have

before me seem to be conveniently classified as follows :—

Basal joint of the hind tarsi not, or scarcely, longer than the second, the first

four joints subequal among themselves; hind cox moderately separated,

_ theabdominal process obtuse; posterior margin of the first segment simple;

hind tibize of the male never calcarate at apex, except in certain small

ally fringed with membranous hairs or a coriaceous border; hind tibice of

The extreme constancy of type throughout the genus is very

remarkable, and necessitates a careful scrutiny in order to distin-

guish the numerous species, which in some parts become closely

adherence to a common type characterizes also the individuals of

the various species, there being but little variability throughout

extended series, even in size of the body, so that with some study,

there can be no more than the usual uncertainty in recognizing

species.

Arkansas (Carlisle). Mr. Wickham.

The individual before me is without doubt a male, and the

species may be known by its large size, strong elytral impressions,

‘elevated suture and inflated hind body. The two approximate

impressions of the pronotum are so feeble, that, were they not

symmetrically placed in the unique type, I should be disposed to

regard them as spurious and accidental ; it is more than probable

that they are inconstant and may disappear altogether.

The sex of the single specimen before me is undoubtedly male,

as shown by antennal structure and the conformation of the

apical plates of the abdomen. Sexual differences in form are

probably very slight. The species may be readily known by its

large size and impressed elytra, with the suture strongly beaded.

Iowa (Iowa City). Mr. Wickham.

The type above described is a female, and the male will ake

bly prove to be more slender. Four specimens from Ohio, in

poor state of preservation, are associated for the present with

formale, but possibly represent a closely allied species, as the

elytra are brighter red and invariably become gradually black in

posterior third or fourth. This Species is said to occur in ant-

nests, but the association is probably in part fortuitous.

Texas (Galveston).

The description of the antenne is drawn from a specimen which

is undoubtedly male, the other does not permit of identification

in regard to sex. Two specimens.

This species almost exactly resembles schaumi in the form and

convexity of the clypeal tooth, but the antennee differ somewhat

in relative lengths of the joints, and the elytra are decidedly

shorter, relatively wider and more strongly impressed near the

suture.

Louisiana, This species may be recognized by the stout, blunt

and convex clypeal tooth, narrowish form, elongate elytra, pale

‘rufous and strongly clavate femora and antennal structure; the

type described appears to be a male, but I am not certain of this,

as the cedeagus is entirely concealed.

Schaumi is of course not a preoccupied name in Connophron,

and, in Kuconnus, schaumz Lucas, is considered by the authorities

of the most recent catalogue as a synonym of tnérusus Schaum,

so the name appears to be perfectly valid for the present species,

and need not be replaced by magister as suggested by LeConte.

Michigan (Detroit); originally described from New York.

The original description would equally satisfy a dozen species of

the genus, and I do not have the type before me at present. The

above outline is drawn from a female specimen communicated by

Mr. Schwarz, and is probably a true representative of flavitarse ;

at any rate it will produce less subsequent confusion to so con-

sider it, whether or not it agrees rigorously with the original and

virtually undescribed type of LeConte. The statement in the

original description that the elytra at the middle are “ fully 4

wider ” than the prothorax, is grossly erroneous for any species

of this group of the genus.

discovered by careful examination under sufficient optical en-

largement.

Texas (Brownsville). Mr. Wickham.

The description applies to the two males before me, the single.

example which may be supposed to be the female Heine smaller,

paler and more rufous in color, with the antenne very slightly

shorter and just visibly more strongly, but quite as gradually, in-

crassate toward tip. The abdomen is dark testaceous in Deane

apical half, and is rather thickly pubescent.

Texas (Colorado River).

The description refers to three male examples, two other speci-

mens taken at the same time, which are undoubtedly the female,

being decidedly smaller in size, still on and more ferruginous

in color and with the antenne scarcely 4 as long as the body, and

more strongly and less gradually Hitabaata through the last four

joints; the femora are equally strongly clavate.

This species is rather closely allied to longicorne, but may be

distinguished by the paler coloration, rather less elongate antenne,

and shorter, stouter and more rhombic form

rounded behind the eyes, which are moderately developed and not noticeably

prominent; pubescence coarse, abundant and flavate; clypeal tooth long and very

conspicuous, parallel, convex, obtuse atapex. Antenne rather short and stout,

2¢ as long as the body, the club decidedly abrupt but with its joints increas-

wide, the sides rather more strongly arcuate just before the middle; apex

rather narrowly rounded; humeral plica strong and somewhat elongate, the

subhumeral impression conspicuous; basal fovese moderate; subsutural impres-

short, the anterior and middle femora strongly clavate, the posterior moder-

ately. Length 1.25 mm.; width 0.6 mm.

Towa.

Dentiger may be known among its allies of the present group by

its small size, relatively very large clypeal tooth, small prothorax

and slightly transverse outer joints of the antenne. The sex of

the single specimen before me is not determinable, and in this

example the pubescence is almost entirely rubbed from the elytra.

transverse; tenth still slightly thicker and strongly transverse; eleventh stout,

obliquely pointed. Prothorax conie, as long as wide, the sides noticeably arcu-

ate; apex more than 14-as wide as the base, the latter 1g wider than the head;

surface perfectly even throughout. lytra rather short, % longer than wide;

obliquely and rather acutely pointed behind from before the middle, not

quite twice as long as the prothorax and 34 wider; sides. arcuate; humeral

plica large and moderately strong, the subhumeral impression large, elongate

and conspicuous; outer fovea very feeble, the inner strong; subsutural im-

pressions rather strong, elongate, the suture finely beaded basally. Legs mod-

erately developed, the four posterior femora quite moderately clavate, the an-

a female.

14. C. ludificanms n. sp.—Elongate-oval, very convex, highly polished

and impunctate, black throughout, the elytra not in the least rufescent, the

legs black ; tibize scarcely piceous, the tarsi flavescent ; antenne: brown; pubes-

cence long, abundant and dark cinereous. Head distinctly wider than long,

transversely oval, subcircular behind, the eyes moderate and but slightly con-

vex ; clypeal tooth moderate in size, broad and rounded. <Antennz much less

longer than the seventh but 4 thicker, oval, fully as long as wide, almost

similar to the ninth and tenth ; eleventh obliquely pointed, much shorter than

the two preceding combined. Prothorax rather small, scarcely as long as wide,

strongly conic, the sides slightly arcuate, becoming feebly sinuate near the

apex, the latter rather more than 44 as wide as the base, which is scarcely 14

wider than the head ; surface perfectly even. lytra elongate, gradually and

acutely pointed behind, fully 44 longer than wide, much more than twice

as long as the prothorax and very nearly twice as wide, the sides more

strongly arcuate behind basal third ; humeral plica and adjacent impres-

sion very short, feeble and inconspicuous ; two basal fovez approximate, deep

and distinct ; subsutural impressions almost completely obsolete, the suture

perfectly devoid of raised margin toward base. Legs rather long, the anterior

femora strongly, intermediate moderately and posterior feebly, clavate. Length

1.65 mm.; width 0.7 mm.

Iowa (Lowa City). Mr. Wickham.

The male type of this species differs from femorale in its larger

size, much feebler elytral impressions, relatively smaller pro-

thorax, larger clypeal tooth and in the absence of any sexual

modification of the anterior femora, these being as usual sparsely

clothed with decumbent hairs, becoming gradually subglabrous

toward base on the upper surface.

In this specimen the cedeagus is fully exposed, and the chitinous

copulatory organ appears to be of the usual type; it is wide,

nearly flat, rapidly narrowed in ogive toward apex, the latter pro-

duced in a short acute and thickened spicule; at each side there

is an acute denticle bearing a long double seta; on the under

surface toward base there is a thick and oval plate, attached

basally, with its edges thin and explanate; the efferent duct prob-

ably protrudes between these plates. In some species it may be

noted that the acute apical spicule becomes wider, and sometimes

transversely truncate at tip.

Canada (Ottawa). Mr. W. H. Harrington.

The antennal and other characters detailed above are taken

from the male, the female being quite similar but with the an-

tennze somewhat shorter, the third and fourth joints quadrate.

This species somewhat resembles fussiger in size and form, but

may be known by the feeble subhumeral impression of the elytra

and long clypeal tooth. It is represented before me by numerous

specimens. |

Iowa (Iowa City). Mr. Wickham.

The single type before me is of undeterminable sex. This

species is very distinct in coloration, and may be known besides

by its narrow form, nearly obsolete humeral plica and impression,

but distinct sutural impressions,and by the subtransverse pen-

ultimate joint of the antenne. 3

mon species, to be readily known by the black color, with ruby

elytra becoming blackish toward tip, subobsolete sutural but

well developed subhumeral impressions of the elytra and small

clypeal tooth. The description is taken from the male; in the

female the form is a trifle stouter,and the antenne are a little

shorter, the third joint being exactly quadrate, the fourth a little

longer than wide, fifth a third longer. The antenne are fre-

quently dusky, with the last joint paler.

Mississippi (Starkville). Mr. H. E. Weed.

This species is quite isolated, even when compared with its im-

mediate neighbors, because of its small size and short ventriculate

hind body. It is allied more closely to brevicorne than any other

Species, differing strongly, however, in its long and pronounced

humeral plica and attendant impression. The three specimens

before me do not exhibit marked sexual peculiarities. |

Pennsylvania (probably near Philadelphia). Closely allied to

fossiger in general form, coloration and in the minute clypeal

tooth, but differing in its smaller size, narrower form, stouter and

more abbreviated antennz and stronger subsutural impressions.

Three specimens of indeterminate sex are before me. :

There can be but little doubt that Say had before him this

species in describing brevicorne. The species identified under

that name by LeConte is however a widely different thing, not

agreeing at all with Say’s description, either in coloration of

the body or nature of the pubescence ; it will be described subse-

quently under the name clavicorne. Say states that brevicorne

resembles clavipes, but has the antennze much shorter and stouter.

Although the antenne in the present species are not remarkably

short or stout when compared with other members of Connophron,

they evidently are when compared with ELuconnus clavipes,where

these organs are remarkably long and slender.

20. C. tenebrosuma n. sp.—Rather stout, black, the elytra faintly rufo-

Rhode Island (Boston Neck); Massachusetts.

The type isa male, as shown by the exposed tip of the cedeagus,

which is a little more broadly obtuse than usual. This species

resembles fossiger and femorale in its very minute clypeal tooth,

but differs from the former in its entirely black color, strong sub-

sutural impressions with strongly beaded suture, and in antennal

structure, and, from the latter, in its simple anterior femora of the

male, stouter form and other characters.

21. C. femorale n. sp.—Elongate-oval, polished and subimpunctate,

black throughout with a piceous tinge, the legs dark rufo-piceous, the an-

Iowa (Iowa City); Michigan—Mr. J. Croissandeau.

The type described is a male, and in this sex the anterior

femora are very strongly swollen, with their anterior side glabrous

in basal half, asperately and sparsely punctate about the middle

of the length, the asperities bearing short hairs, and thence clothed

with the usual long sparse hair to the apex. The female is slightly

shorter and stouter, with the antennz a little less elongate, and

with the club more abrupt but not stouter, the basal joint, espe-

cially, shorter, the second fully twice as long as wide, the third

only a little longer than wide, the eighth not at all elongate.

This species resembles fossiger, especially when the elytra be-

come slightly rufescent from immaturity, but it may be known at

once by the sexual characters of the male, and by the still more

- minute clypeal tooth. Numerous specimens.

22. C. procerum n. sp.—Narrowly fusiform, polished and impunctate,

uniform dark rufo-testaceous throughout, the legs and antennz concolorous;

pubescence long, moderately abundant, pale yellowish in color, rather coarse

on the elytra. Head well developed, nearly as long as wide, subcircular or

_ slightly parabolic behind, the eyes moderate in size, not very convex ; clypeal

tooth very minute, swollen, obtusely rounded. Antennx nearly 14 as long as

the body, stout, the club slightly abrupt and with its joints increasing just vis-

ibly in width ; second joint * as long as the first, and, at apex, nearly as thick,

strongly obconic, 14 longer than wide, as long as the next two; three to six

The single specimen before me is of undetermined sex, but the

species will be readily identified by its narrow form, feeble humeral

in this portion of the genus, although common among the allies

of capillosulum.

Pennsylvania and New York to Iowa (Iowa City).

The description is drawn from the female, but the male differs

but slightly, being a little smaller and darker in color, the elytra

uniform dark piceous-brown and with longer sparse erect sete

more evidently interspersed among the coarse recurved hairs ;

the antennal differences seem to be very slight.

This species is said by LeConte to inhabit the nests of a small

black ant, but I have seen it associated also with a large brown

ant; it is probably not truly myrmecophilous, but associates itself

occasionally with ants of various species, as in the case of a very

large number of Coleoptera of widely diverse families.

In describing Scydmenus brevicornis, Say states that the elytra

New York (Hudson River Val.). Mr. H. H. Smith.

A small but distinct species, which may be easily identified by

its uniformly blackish color with pale legs, narrow form of body,

somewhat short and recurved pubescence of the elytra and com-

paratively large head. The single specimen before me is not ab-

solutely identifiable as to sex, but is apparently a male.

Northern [llinois. Mr. F. M. Webster.

The sex of the single type before me is not clearly determin-

able without dissection. The species may be known at once

among its few allies with coarse recurved elytral pubescence, by

its elongate and slender antenne; its pale coloration may possi-

bly be in part due to immaturity.

Only the three last of the six following species really form a

natural group, the three first, which belong structurally with

furtivum and the preceding species, being associated solely

on account of their very small size for convenience in identifica-

tion. :

Pennsylvania (Westmoreland Co.). Mr. Schmitt.

Sexual characters cannot be detected in the specimens at hand

and are probably very slight. The species can only be confounded

with humile and pallidum, but may be known from both by the

relatively larger and longer elytra and less strongly clavate an-

tennee, and, from the latter, also by its decidedly larger size.

Coleopterological Notices, VII. 493

I have not been able to distinguish any sexual differences in

the specimens before me. This species is closely allied to humile,

but may be distinguished by its narrow form, sparser pubescence,

less developed humeral plica and impression, more slender an-

tennze and non-carinate clypeus.

32. C. angusticolle n. sp.—Moderately stout, the hind body somewhat

inflated, polished, impunctate, pale rufo-testaceous throughout, the elytra still

Texas (Colorado River).

The antennal tubercles in this species are quite pronounced, and;

in the depression between them and at some distance behind the

line of the antenne, there is in the male a small elongate-oval area

which is finely and closely punctate. The description applies to

the male, but the female does not differ even in antennal structure.

Rhode Island (Boston Neck).

The male, from which the above characters are taken, differs

but little from the female, except that the penultimate joints of

the antenne appear to be a little more transverse in the latter.

Between the antennal tubercles in the male there is a subtriangu-

lar patch at the anterior margin, which is densely and strongly

punctate and more closely pubescent.

This species is abundant under fallen leaves in rather moist

woods, and may be known by its small size, minute clypeal tooth

and male sexual characters. The erect vestiture of the elytra is

nearly similar to that of the large species allied to flavitarse.

There is no distinguishable structural variation, even in size, in

the ample series before me. :

Florida.

This species is closely allied to frontale, but differs in its nar-

rower form, paler color, smaller head with relatively larger eyes,

and in some other details of structure. The male, which serves.

as the type of the description, has the anterior margin of the

front finely and closely punctured and pubescent from side to

side between the antenne, the punctures not so large as in fron-

tale, and not confined so distinctly to a posteriorly angulate area.

As in many other species, the scars left by fallen hairs on the

elytra are quite distinct, but not exactly in the nature of punc-

tures. The abdomen is black with the apex pale. Sexual marks

are not discoverable.

Integrum is a distinct species in the present group because of

its larger size, black color and long antenne, but it resembles a

small femorale to some extent. The pronotum seems in certain

lights to exhibit feeble traces of the bisected transverse impression

so usual in this peculiar group of small obscure species, but it is

too faint to be at all decisive.

California (San Bernardino Co.). Mr. H. C. Fall.

The basal segment of the abdomen is simple and normal

throughout, and the single type before me is a male, as shown by

the protruded tip of the copulatory spicule, but there are no ex-

ternal sexual marks.

The individual lenses of the eyes are very feeble and widely

separated posteriorly, but convex and subcontiguous anteriorly.

‘The gradually acutely conical apex of the eleventh antennal joint

is a peculiarity which I have not noticed elsewhere.

The description above given is taken from a Louisiana female,

and the series from Austin, Texas, before me, agrees fairly well;

in this series the male differs from the female in being slightly

stouter. The spur of the hind tibie in the male is slender and

not quite half as long as the tarsus. As in many other species.

the abdomen is dusky, becoming paler toward tip.

The sex of the type is not discoverable at present, but the

species may be readily known by its uniform pale coloration,

carinate clypeus, unimpressed pronotum and other characters.

Two specimens. 7

Decorum is allied rather closely to hirtellum but differs in its

smaller size, more slender antenne with relatively fully as stout

but shorter and more gradually formed club, shorter elytra and

more slender legs.

California (Pomona, Los Angeles Co.). Mr. H. C. Fall.

The single male type before me has a somewhat slender and

contorted spur projecting obliquely from the tip of the hind tibie,

and distinctly less than half as long as the tarsus. This species

is related to anale and ventricosum, but differs from both in the

shorter and more recurved pubescence of the elytra unmixed with

longer erect hairs.

Central Illinois. Mr. F. M. Webster.

The first ventral segment is almost normal, having merely a

slightly more developed coriaceous hind margin than the suc-

ceeding segments. The sex of the single type is not determin-

able.

This species differs from castaneum in its shorter elytra, more

elongate and larger prothorax, still larger and more coarsely

faceted eves, smaller head impressed between the antennal promi-

nences, and in numerous other characters of minor importance.

The eyes are not so large as in testacetpes, and the prothorax is

relatively much larger than in that species or inerme ; the body is

much more obese than in ¢rzviale.

The first abdominal segment is simple, but with the coriaceous

hind margin somewhat distinct. The sex of the type example is

Pennsylvania (Westmoreland Co.). Mr. Schmitt.

The basal segment of the abdomen is broadly arcuate at apex

and somewhat elevated above the general level as in the second

subdivision of the genus, with which however the present species

cannot be placed because of tarsal structure. In the type, as-

sumed to be the male, this segment is densely clothed with long

submembranous hairs throughout. The female is smaller, darker

and more slender than the male and has the pubescence of the

first segment normal.

This species may be known by its small and transversely im-

pressed pronotum, strong humeral plica and abdominal structure.

the eyes, which are rather small and but slightly prominent ; antennal promi-

nences very feeble, the surface not noticeably impressed between them ;

clypeus not carinate, short, rectilinearly truncate. Antenne a little longer

Pennsylvania (Westmoreland Co.). Mr. Schmitt.

The first abdominal segment in the type is large, arcuate at.

apex and extends slightly over the second segment as in the second

section of the genus; itis sparsely and inconspicuously pubescent,

but the apical margin is fringed with a laminate porrect and mem-

branous border which seems to be split into narrow scale-like

pieces. The first four tarsal joints are eens in length. The

sex of the type is undetermined.

This species is allied to castaneum, differing in its rather smaller

size, paler color, more slender antennal club, and especially in

abdominal structure and in its much shorter and less conspicuous:

humeral plica and impression.

tempora obtusely subangulate; eyes moderately large, slightly prominent, not

extending to the middle; antennal prominences strong, rather approximate,.

separated by a SronbHnCed depression; clypeus even, transversely rectilinear

at apex. Antennzx slender, longer than the head and romana, the club slen-

der and very gradual in formation; second joint subcylindric, about 14 longer

than wide, as long asthe next two and slightly thicker; three to six equal in

width, cylindric; three, four and five equal and quadrate; six perceptibly

fore the middle, the sides rather more strongly arcuate there than toward base

and apex; humeral plica narrow but strong and somewhat elongate, the im-

pression well marked but small; foveze approximate, rather deep; subsutural

impressions distinct, the suture strongly beaded basally, the bead expanded at

Rhode Island ( Boston Neck ).

Coleopterological Notices, VII. 439

The sex of the single individual before me cannot be determin-

ed at present. The pale color of the type may be in part due to

immaturity.

This species may be readily known by its minute size, very

gradual antennal club and small head with deep frontal impres-

sion, as well as by its impressed pronotum.

Oregon (Huntington). Mr. Wickham.

The first ventral segment is large but simple and not fringed,

the apical margin broadly arcuate and widely overlapping the

second segment. No sexual characters are observable in the

unique type. The species may be recognized by its very short

elytral pubescence, subobsolete transverse pronotal impression

and antennal structure.

Although inhabiting a Pacific State, this species cannot be re-

regarded as belonging to the true Pacific coast faunal region,

as the town of Huntington is on the extreme eastern border.

Pennsylvania (Westmoreland Co.). Mr. Schmitt. —

No sexual marks can be discovered in the two examples before

me; there will, however, be no trouble in identifying this distinct

species, because of its small size, coloration of the body and pe-

culiar form of the prothorax.

Pennsylvania (Westmoreland Co.). Mr. Schmitt.

The form described above is the male, and the female differs in

having the elytra rather shorter and relatively more dilated, the

head slightly smaller, circularly rounded behind the eyes which

-are moderate in size, anterior and visible from above, and in hav-

ing the penultimate joints of the antennz shorter and more trans-

verse; the middle of the vertex is however broadly impressed,

nearly as in the male, and the antennal prominences are relatively

more marked, but there is no frontal punctulation.

This and the preceding are by far the most minute of the entire

‘genus, and differ besides in presenting strongly marked cephalic

modifications in the male, but they are perfectly normal members

-of the sents in general structure.

Rhode Island (Boston Neck); New York; District of Co-

This is a distinct species and is apparently common and widely

diffused in the northern Atlantic States. It resembles fulvum,

but differs in its piceous-black color and much larger size; from

trifidum it may be known by its less ventricose form and much

smaller subhumeral impression, and, from debilitans, which it re-

sembles most of all, by its larger size, darker color, much longer

elytra, narrower prothorax and shorter but stouter antennal club.

The description is drawn from the male, the female however not dif-

fering in any external aspect. It is represented by a large series.

and some individuals are pale, probably from immaturity.

Pennsylvania (near Philadelphia). —

The single specimen, which is probably a male, represents a

species allied to fulvum and trifidum, but differing in its much

stouter antenne, especially in the funicular portion. The subhu-

meral plica and impression are much more pronounced than in the

former, but rather less so than in the latter, and the subsutural

impressions and clypeal tooth are more developed than in either

of those species. In form it more nearly resembles fulvum, being

less stout than trijidum. The last two segments combined occupy

nearly half of the entire abdomen. |

61. C. trifidum n. sp.—Somewhat stout, suboval, polished, subimpunc-

tate, pale brownish-testaceous throughout, the legs and antenne concolorous ;

pubescence rather abundant, pale, coarse, rather short and recurved on the

elytra, where it is mingled with a few widely dispersed and erect tactile sete

of moderate length. Head moderate, but very slightly wider than long,

rounded behind, the eyes small and slightly convex ; antennal prominences

very feeble, the front scarcely impressed ; clypeus simple, sparsely asperate,

the apical margin with an exceedingly minute and obtuse median tooth.

Antenne barely as long as the head and prothorax, slender, the club abrupt,

stout and 3-jointed ; second joint very feebly obconic, 14 longer than wide,

longer and much wider than the next two; three to six equal, cylindric,

about 44 wider than long ; seventh nearly 14 wider than sixth, fully 14 wider

ninth abruptly 44 wider than the eighth, fully %£ wider than long; tenth

similar to the ninth but just visibly wider ; eleventh not quite as long as

the two preceding. Prothorax conic with very feebly arcuate sides, about as

long as wide ; apex truncate, % as wide as the base, which is nearly 14 wider

than the head ; surface perfectly even and unimpressed. Llytra about 14

Wisconsin (Bayfield). Mr. Wickham.

A small species, closely allied to fulvum, but differing in the

more dilated seventh and eighth antennal joints, larger size, more

ventriculate form and much stronger humeral plica and adjacent

impression. It is represented before me by a single specimen of

indeterminate sex but in all probability female. The elytra are

sparsely and feebly punctulate, particularly toward base.

Appalachian mountain system, from New York to northern

Georgia. This species may be known at once by its minute size,

3-jointed club, feeble modification at the base of the elytra, ab-

dominal structure and pale coloration. It is said by LeConte to

occur under pine bark, but its very convex form would suggest

the accidental nature of such a habitat. The type is a male, the

copulatory spicule being very slender and without a terminal

button.

Texas (Austin).

A rather large and distinct species, which may be distinguished

from any other of the present section by the small but pro-

nounced median tooth of the clypeus; this tooth is not elongate,

however, as in the first section of the genus, but is equilateral

Pennsylvania (Westmoreland Co.) Mr. Schmitt. —

The male described above serves as the type of a species allied

in general to capillosulum, but with very much feebler subhumeral

modifications of the elytra. It is rendered very distinct by the

conformation of the terminal hind tibial spur of the male, which

is slender and oblique as usual, scarcely half as long as the tarsus

and bifurcated from about the middle, the diverging angle being

Pennsylvania ( Westmoreland Co.). Mr. Schmitt. |

This species is closely allied to bifidum, but is smaller, with

relatively larger prothorax and narrower elytra, much larger and

stronger humeral plica and impression and strongly beaded

suture. It further differs in the conformation of the posterior

tibial spur of the male, this being likewise abnormal in structure.

This spur is much longer than in bifidum, being fully $ as long

as the tarsus, and is split from near the base into three long

slender filaments, which become more or less contorted at their

tips. The constancy of this singular modification cannot be

stated, as I only have a single male and two females before me,

but it is probably variable in degree to an appreciable extent ; the

splitting of the spur into filaments is, however, in all probability

not the result of accident.

Iowa (Iowa City). Mr. Wickham.

This species is closely allied to capillosulum and proximum, but

differs from the former in its larger size, more elongate elytra,

more elongate head, which is much less broadly rounded behind

and with the eyes not larger but rather more abruptly prominent,

and, from proximum, in its larger eyes; from both it differs in

the very much smaller and less conspicuous subhumeral impres-

sion, which character will distinguish it at once. A single female |

example. | :

The eyes, qui‘e unexpectedly, are perceptibly larger and more

conspicuous in the female than in the male of capillosulum, and

the head is a little shorter and broader in that sex, so that in

making comparisons between these species the sex should be care-

fully noted.

New York (Hudson Valley). Mr. H. H. Smith.

A somewhat small species, which is quite distinct by reason of

its large and prominent eyes; it can be distinguished from small

specimens of nigrum and atrum by the coloration and somewhat

transverse penultimate joints of the antenne, and from paganum

by the color and by its shorter and broader head with larger eyes.

It is represented before me by the female only.

Georgia and Louisiana. A rather small species, described

above from the male, in which sex the hind tibiz are provided at

tip with a short slender spur, scarcely 2 as long as the tarsus, the

latter slender and filiform.

This species may be distinguished by its rather small size, not

strongly inflated hind body, having the subhumeral modifications

strong, by its strongly clavate femora and other characters. It

is related most closely perhaps to longipilosum, but differs in its

larger prothorax, less inflated hind body and very much shorter

spur of the male hind tibie.

Illinois (northern). The terminal spur of the hind tibiz in the

male is straight, oblique, bent at base, simple and slender and is

not quite half as long as the tarsus. The description is taken

from the male, but the female does not differ observably. Two

specimens. ,

This species differs from paganum in the longer antennal club,

with the penultimate joint not transverse, and from nigrum in its

smaller size and relatively much larger subhumeral impression.

It agrees throughout with the original description of Anthicus

politus of Say, the position of which has been so long in doubt.

punctate, red-brown, the antenne concolorous; elytra and legs throughout

pale testaceous; pubescence abundant, rather fine, pale, very long, erect and

conspicuous on the elytra. Head only slightly wider than long, broadly para-

bolic behind the eyes, which are rather small and only moderately prominent ;

antennal prominences large and very feeble; clypeus long and well developed,

flat toward tip, with a few fine setigerous punctures, the apical edge perfectly

even and without trace of median protuberance. Antennx rather slender, 14

as long as the body, the club narrow and gradual in formation ; second joint

very feebly obconic, fully 144 longer than wide, rather longer than the next

two and distinctly wider ; three to six equal in width, smooth and cylindric :

obliquely and gradually pointed and rather longer than the two preceding.

Prothorax conic with very feebly arcuate sides, as long as wide; apex rather

more than 14 as wide as the base, the latter fully 14 wider than the head ;

surface with two approximate and distinct transverse impressions near the

base. Elytra % longer than wide, distinctly more than twice as long as the

prothorax and #6 wider, gradually narrowly parabolic at apex, widest before

Pennsylvania (Westmoreland Co.). Mr. Schmitt.

The male described above has the spur of the hind tibiae slen-

der, perfectly straight and simple, oblique in direction, being

bent abruptly at base and is notably long, being rather more than

2 as long as the tarsus. The species may be readily known not

only by this character, but by its rather elongate elytra, strongly

modified at the humeri, long pubescence, pale coloration and

other characters. The last two segments of the abdomen are

still paler as usual. Several specimens.

wider than long, subcircular behind, the eyes rather large, convex and promi-

nent ; antennal prominences almost obsolete, the front not definitely impressed ;

clypeus even, the apex rectilinearly transverse, without trace of median pro-

jection. Antenne only slightly longer than the head and prothorax, rather

slender but with the club pronounced and rather abrupt ; second joint feebly

obconic, nearly 14 longer than wide, as long as the next two and thicker ;

Pennsylvania (Westmoreland Co.). Mr. Schmitt.

The two specimens before me are both females, but the species

can readily be distinguished from capillosulum, and other allied

forms, by its smaller size, shorter, coarser and less abundant

elytral vestiture, much shorter antenne with transverse penul-

timate joints, and by the very faint transverse impression of the

pronotum. |

bolic behind, the eyes only moderately large but very convex and prominent;

front distinctly and narrowly concave between the feeble antennal prominences;

clypeus smooth and polished, rectilinear at apex, with the feeblest possible

rounded inequality for a short distance at the middle. Antennx slender,

about 14 as long as the body, the club narrow and very gradual in formation;

second joint much shorter than the first, about 2g longer than wide, as long as

the next two and much thicker; three to six equal in width, cylindric; third

slightly thicker than the two preceding and nearly as long, obtusely pointed

and scarcely at all oblique at tip. Prothorax well developed, nearly as long as

wide, conic with slightly arcuate sides; apex 35 as wide as the base, which is

rather more than 14 wider than the head; surface transversely and rather.

strongly impressed near the base, the impression feebly interrupted at the

This species is somewhat aberrant in its nearly simple basal

segment of the abdomen. It may be recognized by the narrowly

oval form, rather sparse and coarse elytral vestiture and other

‘characters. The single male in my cabinet has the terminal spur

of the hind tibiz rather stout, straight and somewhat more than

half as long as the tarsus. | :

Canada (Ottawa). Mr. W. H. Harrington.

One of the smallest species of ‘this section of the genus and

readily identifiable by the small prothorax, rather large and

prominent eyes, blackish coloration and by the form of the spur

terminating the hind tibiz in the male, this being unusually short,

not quite a third as long as the tarsus and contorted toward tip;

it is however simple in structure and very finely acuminate.

The description is drawn from the male, but the female does not

differ, except in being a trifle less stout and with a still narrower

antennal club. Two specimens.

This species, which is represented by the female only, is some-

what similar in appearance to nigrum and atrum, but differs from

both in its smaller size and distinctly transverse penultimate

SMICROPHUS pn. gen.

In general organization the two minute species constituting

this genus are intimately allied to Euconnus; but they have two

characters which cannot be harmonized with any variation of that

complex, and I have therefore been obliged to separate them.

The head is far exserted as in Euconnus, but the eyes are large,

very prominent and situated at the middle of the sides. The other

character is quite extraordinary in the present group, though

common in the Eumicrini, and resides in the fact that the met-

episternum is broadly visible at the sides of the body. In Eu-

connus it frequently happens that this piece is exposed by acci-

dent, if the elytra be not placed closely against the body, but

here it appears to be a true exposure and cannot be entirely ac-

counted for in that way.

The head is usually small, ad while both the head and elytra

are glabrous, the prothorax Heiaiies with unusually developed stiff

spiculesand hairs. The elytra, legs and palpi are as in Euconnus,

and the pronotum has two feeble subbasal foveze near the middle

but is otherwise unmodified. The hind coxe are moderately sepa-—

‘rated and the mesosternum rather feebly carinate. The antenne

are moderate in length and have a 4-jointed club.

The two species may be separated by the following characters :—

Black throughout, larger, the elytra more inflated; head less minute, the eyes

relatively smaller, separated on the vertex by twice their own length.

Black, the elytra dull rufous; head very small, the eyes relatively larger,

In distribution this genus is confined as far as known to the

regions east of the Rocky Mountains, but there is a bare possi-

bility that it may be very nearly identical with the form sepa-

rated by Mr. Croissandeau (Ann. Fr., 1893, p. 225) under the name

Microscydmus.

1. S. leviceps n. sp.—Rather stout and pyriform, polished, impunctate,

black throughout ; legs and antennz rufo-testaceous, the club of the latter

dusky ; head and elytra glabrous, the former with a long seta immediately be-

hind each eye and another above the point of antennal insertion, and the latter

with a series of three or four erect sets near inner third and one or two exterior

to this ; prothorax bristling on the flanks with numerous stiff erect hairs and

spicules, which are fine on the disk anteriorly and nearly wanting posteriorly.

ScYDMAENINI.

The substitution by Reitter of Cyrtoscydmus Mots., for Scyd-

menus Lat. (auct.), does not appear to be warranted, although it

should be stated that the original literature of the subject is not

fully accessible to me at present. In looking over the article on

Scydmeenide in the “ Analecta Entomologica” of Schaum, I can

discover only two species which had been previously referred to by

Latreille. One of these is godarti, which was originally described

and named by that author, and therefore, in all probability, in-

tended by him to be the type of his genus Scydmeenus, and the

other an identification of the Fabrician hellwigz, which, accord-

ing to Schaum, was not hellwigi at all but the species afterwards

named tarsatus by Muller. If the literature quoted by Schaum

is complete, the case is therefore clearly determinable in favor of

the present identification of Scydmeenus.

The Scydmenini comprise two genera within our limits as

follows :—

Body ventricose ; prothorax cordiform, the pronotum impressed, foveate or

PUDCSe AGING WABRr. irae lores stat aden wassge Cceweut eter ean otis Scydmezenus

Body linear ; prothorax obovoidal, the pronotum wholly devoid of fovez or

Bor MOUS, OF BIT KING alctisivescs can ceed cpincndnsnshouessaveaweesunears Catalinus

470 Coleopterological Notices, VII.

- Catalinus is represented by a single species peculiar to the Pa-

cific coast fauna. Scydmeenus is abundant in species and dis-

tributed about equally over both slopes of the continent.

_ The European Neuraphes is closely allied to Scydmenus, but

differs in having the fovez at the base of the elytra spongiose and

not nude, and therefore forms a transition to the Cephenniini.

The long carinse at the sides of the prothorax toward base also

form a character which leads onward to the acute thoracic mar-

gins of Cephennium. Although Neuraphes therefore, is the most

obvious bond between Cephennium and the Scydmeenide subuli-

palpi, there are many profound differences, especially in the

head and in the hind coxe, as well as in the entire facies of the

body.

SCYDM ENTS Latr.

Among the genera common to Europe and North America,

Scydmeenus is the only one, except Cephennium, which so far as

known, is distributed throughout the United States; it is well

represented in the Atlantic regions, and, on the Pacific coast,

forms one of the most prominent types of the family. It can be

distinguished at once from any of the Euconnini by certain gen-

eral habital features, such as the smaller prothorax more dilated

anteriorly and more elliptical and convex elytra.

The head is always narrower than the prothorax, with the cly-

peus large, simple and truncate at apex, more or less dilated and

subangulate at the sides and separated from the front by a short

transverse sulcus, the neck wide and the nuchal constriction

moderate in depth, the occiput. not having the deep vertical base

so general in the Euconnini. The eyes are at most median in

position, generally subbasal, and vary much in size, becoming

large and extremely prominent in Brachycepsis. The maxillary

palpi are well developed, with the second joint slender, bent and

clavate at apex, the third elongate, obconic, with rounded sides

and the fourth distinct though slender and very finely aciculate,

being occasionally more than half as long as the third. The an-

tenne are incrassate but never have a pronounced club, although

the three outer joints sometimes constitute a feeble club, and, in

one species of Brachycepsis, the five outer joints may be imagined

to have same status. eae ee :

The prothorax is always dilated anteriorly, narrowed toward

_ Coleopterological Notices, VII. 471

base and sinuate at the sides behind the middle, but the nature of

the sculpture near the basal margin differs very much in the

several subgenera. The scutellum is always distinct, except in

Parascydmus, where it becomes minute. The elytra are oval or

elliptical, generally very convex and frequently punctured in a

conspicuous manner, the basal impressions exceedingly small and

feeble in Scydmenus proper, but well developed in Brachycepsis

and Taphroscydmus; they narrowly overlap along the suture

posteriorly, the apex generally subtruncate with nearly right

sutural angles, but becoming broadly rounded witha feeble enter-

ing angle in some species of Brachycepsis, the dorsal pygidium

in these cases being usually visible but always nearly horizontal ;

humeri more or less visible in all except three of the species of

Parascydmus, where they are wholly obliterated, but almost ob-

solete also in Scydmenus perforatus and Taphroscydmus cali-

fornicus.

The mesosternum is more or less carinate, with the episternum

tumid and setose; met-episterna entirely covered by the elytra.

Abdomen normal, with the first four segments short, the last two

much developed in some forms of Brachycepsis. The hind coxe

are very narrowly separated, with the small prolongation of the

metasternum between them deeply and narrowly cleft. The legs

are generally long and well developed, with the femora moderately

or feebly clavate, the anterior very strongly so in the subgenus

Scydmenus. Tarsi varying in structure in the several subgenera.

The secondary sexual characters generally affect the anterior

femora in the subgenus Scydmeenus, but in turbatus the hind

trochanters are alone modified. In Brachycepsis they affect the

tibize, hind trochanters and abdominal apex in various ways, ac-

cording to the species, while in Parascydmus they appear to be

altogether wanting. : |

The species are somewhat numerous and may be assigned to

four strongly differentiated subgenera as follows :—

Head not impressed ; pronotum with four subbasal fovee but frequently with

confused sculpture near the base, the prothorax dilated anteriorly, narrowed

and more or less feebly sinuate at the sides to the base ; hind tarsi elongate,

with the four basal joints decreasing in length ; scutellum distinct.......... I

tenne about 5 as long as the body, quite strongly incrassate to-

ward apex, the club not distinct; second joint obconic, nearly

others found in the same geographical regions, so that a detailed

description is necessary. Perforatus may be known by its rather

narrow form, long and narrowly oval, gradually pointed and

very coarsely punctate elytra and somewhat strongly incrassate

antenne, with the penultimate joints moderately transverse.

In the male from Iowa the penultimate joints of the antenne are a

little less transverse, and the eleventh more elongate than in the

male described above, being equal to the two preceding together.

The anterior femora of the male in this species, as well as in

badius, are swollen much more than in the female and are angu-

late above.

2. S. badius n. sp.—Rather strongly ventricose, polished, impunctate

anteriorly, the elytra coarsely but sparsely punctate; body piceous in color, the

elytra generally much paler; legs and antennz pale testaceous ; pubescence

moderately abundant, shorter and inconspicuous anteriorly, rather long stiff

fulvous and suberect but strongly recurved on the elytra. Head much wider

than long, the eyes prominent and rather large, much longer than the tem- |

pora ; edges of the front above the antenne slightly elevated. Antenne a lit-

tle less than 4% as long as the body, gradually and moderately incrassate

toward tip; second joint almost as long as the first but thinner, feebly

obconic, 3 longer than wide, 44 longer than the third and much thicker ;

three to six equal in width, cylindric ; third %, fourth 1, fifth nearly 14, sixth

ninth %, tenth 14, thicker than the eighth, 14g and % wider than long respec-

tively ; eleventh fully as thick as the tenth, about as long as the two preced-

ing, very obliquely and acutely pointed. Prothorax about as long as wide,

fully 44 wider than the head, dilated and narrowly rounded laterally at apical

third, the sides thence moderately convergent and broadly sinuate to the base ;

four subbasal foveze not connected but very irregular in form, the less basal

and larger depression at each side enclosing a small setigerous tubercle as is

frequently the case also in other allied species. Scutellum distinct, parabolic.

Canada (Ottawa).

The anterior femora of the Pennsylvania male described above

476 Coleopterological Notices, VII.

are strongly swollen and angulate above beyond the middle, the

apical slope of the angle nearly straight in profile and minutely

irregular or subserrulate. In the female these femora are more

clavate than the other four but are simple, and in that sex the

antennz are a little shorter but nearly similar, except that the

fifth and sixth joints are distinctly thicker than the two preced-

ing. In general form of the body and outline of the elytra the

two sexes are almost exactly similar. The head seems to be rela-

tively smaller in some females than in others.

This species, while allied to perforatus, differs conspicuously

in its more dilated hind body and perceptibly less coarse and

somewhat sparser punctures, also in its shorter, more fulvous and

more recurved pubescence of the elytra, much more irregular sub- —

basal fovez of the pronotum, color and other characters. In the

series of eight specimens before me the largest and smallest indi-

viduals are both females. The single example from Ottawa, com-

municated by Mr. W. H. Harrington, has the elytra more elon-

gate, but does not appear to differ much otherwise; it is pale

testaceous throughout, as however are several of the Pennsyl-

vania specimens. The Virginia representatives have the pro-

thorax rather more inflated anteriorly.

3. S. comjux n. sp.—Moderately stout, polished, impunctate anteriorly,

the elytra strongly but sparsely and not very coarsely punctate ; body piceous-

black, the elytra slightly paler and rufescent, the abdomen slightly paler at

apex ; legs and antenne rufo-testaceous ; pubescence moderately abundant,

rather long coarse pale semi-erect and recurved on the elytra, shorter and less

conspicuous anteriorly. Head much wider than long, the eyes rather well de-

veloped, convex, longer than the tempora. Antenne a little less than 14 as

long as the body, gradually incrassate toward tip ; second joint as long as the

first but thinner, feebly obconic, 14 longer than wide, only slightly longer

than the third but obviously thicker ; third and fourth narrowest, cylindric,

equal in width, % and 14 longer than wide; fifth and sixth just visibly

thicker, 14 and }4 longer than wide ; seventh nearly 14 thicker, suboval,

as wide as long, very nearly as wide as the eighth, which is more than

44 wider than long and conic at apex ; ninth and tenth almost exactly equal,

fully #5 wider than the eighth, strongly obtrapezoidal and transverse, nearly

1g wider than long; eleventh about as long as the two preceding and not

wider, obliquely and acutely pointed. Prothorax not quite as long as wide, 4

wider than the head, only moderately inflated and rounded laterally toward

apex, the sides feebly convergent but distinctly sinuate toward base ; four

subbasal foves isolated and not jointed by impressions but irregular in form,

the irregular cluster at the sides deep. lytra suboblong-oval, % longer than

The single type before me is probably a female, but the species

-can be readily distinguished from perforatus by its more oblong

elytra, with more basally exposed humeri, obvious subsutural im-

pressions with elevated suture, and smaller and still sparser ely-

‘tral punctures; the head is larger than in perforatus, and the

prothorax is less swollen anteriorly and less narrowed at base.

North Carolina (Asheville).

The sculpture and modified front of the head may be a

sexual characters to some extent, but there are no other exposed

features which may enable us to determine the sex of the unique

type. The anterior femora and posterior trochanters are simple.

The four basal joints of the hind tarsi decrease gradually in

length. This species and the next depart from all other Ameri-

can representatives of the genus in the cephalic characters

alluded to.

Texas (near Austin).

The single specimen represents a species closely allied to punc-

triceps, but differing in its smaller size, smaller elytra, relatively

larger prothorax and smaller head, much longer pubescence,

shorter antennee and’ several other characters. The punctures of

the head in this species bear each a short stiff and erect hair,

while in puncticeps they are nude, although the type specimen is

in a perfect state of preservation. The type above described is

probably the male. :

California (Siskiyou, Humboldt, Sonoma and Nevada Cos.).

This is a very abundant species in the northern and hilly parts

of California, probably extending in its range much further to

the northward. The description is drawn from the male,in which

sex the anterior femora are a little more strongly clavate, the thick-

ened portion rather strongly rounded but not angulate and at a

point much nearer the apex than in the eastern species, with the

apical slope very rapid and feebly granulato-serrulate. The fe-

male differs scarcely at all in antennal structure, but has the

elytra a little more inflated. There is but little similarity between

this species and sparsus, it being much larger, more ventricose

and much more strongly sculptured.

California. This species is one of the smallest of Scydmenus

proper and may be knewn by its coloration, sparse and rather

small elytral punctures and other characters.

California (Marin and San Francisco Cos.). The male second-

ary characters of this species differ conspicuously from those of

the allied but much larger pacificus, the hind trochanters being

Pennsylvania (Westmoreland Co.). Mr. Schmitt.

The type described above appears to be a male, but I can find

no obvious secondary sexual structures and the abdominal apex

is but little modified. In the female the elytra are somewhat more

briefly oval and more inflated, and the antenne are slightly

shorter.

The long, erect and very conspicuous pubescence of the elytra,

black color and transversely impressed head, will readily identify

pubipennis among the species of Brachycepsis.

Pennsylvania (Westmoreland Co.). Mr. Schmitt.

A very small species of rather elongated form, but otherwise

closely resembling corpusculum. It may be separated at once,

however, by its non-carinate prothorax with thesides not straight

~ Queen Charlotte Islands (Massett—Mr. J. H. Keen), Sitka—

Mannerheim and California—Motschulsky (possibly in error).

This distinct species may be identified immediately by the very

deep and conspicuous excavations of the head; the rather large

and very profound excavation above each eye was not observed

by either Mannerheim or Motschulsky.

The two specimens sent to me by Mr. Keen are evidently

males, but there are no visible crural modifications. The exca-

vatiou at the base of the head will prove to be perfectly asexual,

though the pits above the eyes, and particularly the tumidity of

enced somewhat by sex in extent of development.

CATALINUS np. gen.

This genus has for its type, and only representative thus far

known to the writer, a small, very slender and linear species, de-

scribed by LeConte under the name Scydmenus angustus. It is

unmistakably allied to Scydmzenus in general organization, but

differs especially in the form and structure of the prothorax.

The eyes’are subbasal, the palpi normal, with the fourth joint

slender and aciculate, and the scutellum very small and in great

part hidden by the arcuate base of the pronotum. The elytra

are evenly and broadly rounded or subtruncate at tip, with the

sutural angle right and only minutely blunt, entirely covering the

dorsal pygidium and mutually overlapping on the stiture toward

apex, though only to an extremely slight degree. The charac-

ters of the under surface are those of Scydmeenus, except that the

last ventral segment is not unusually developed; the hind cox

are very approximate, and the posterior tarsi moderate in length,

with the four basal joints subequal. .

The prothorax is evenly obovoidal, with rounded base and

more broadly rounded apex, and is wholly devoid of any trace of

subbasal impressions or lateral foveee.

OPRESINI.

The remarkable succession of minute species which constitute

this tribe are only beginning to be known, and almost all the types

here referred to are due to the patient and skillful collecting of

Mr. Schmitt, within a single limited section of country among the

mountains of Pennsylvania, to which I have already alluded.

Among the other tribes with the fourth palpal joint subulate and

oblique, they may be known at once by the rather long proster-

num before the cox. They are assignable to three quite distinct

-genera, which may be briefly defined as follows:— _

.Eyes median; neck strongly constricted; antennal cavities narrowly separated ;

pronotum impressed at base.

Scutellum completely invisible and covered by the pronotum, the elvtral

It is almost certain that the Scydmeznus ovithorax of Brendel,

forms another genus in this tribe; if this be not the case, how-

ever, there is no known representative west of the Missouri River.

OPRESUS n. gen.

The species of this genus are the most minute of the Scydme-

nid, and could only be compared with Ptilium of the Tricho-

pterygide in point of size. They are probably numerous, but only

three or four are known at present. The body is narrowly sub-

oval, feebly ventriculate, rather strongly convex, and clothed with

very short and rather sparse pubescence. The head is well de-

veloped, borne on a stout but deeply constricted and exposed

neck, and is but feebly inclined downward, the eyes median and

generally rather well developed, the antenne of the usual type in

neighboring tribes of the Scydmenidz subulipalpi, the three

outer joints forming a distinct club. Front between the antennal

cavities narrow, nearly vertical and somewhat prominent ; labrum

transverse,truncate, the mandibles rather small, circularly rounded

externally. Prothorax obovulate, the subbasal markings fine,

consisting of two minute united median foves and another near

each basal angle. Prosternum before the coxe rather long and

finely puberulent as inthe other genera of the tribe. Scutellum

completely wanting and covered by the pronotum. Elytra oval,

somewhat individually rounded at apex, the dorsal pygidium.

exposed at tip and broadly rounded.

The middle coxe are contiguous, the posterior very narrowly

separated, the narrow process of the metasternum between them

deeply and finely cleft as in Scydmenini, extending virtually to

the sides of the body. First ventral segment longer than the

next, the last two moderately elongate. Legs very short and

rather stout, the hind tarsi short, with the four basal joints equal;.

claws short and strongly arcuate. Secondary sexual characters.

appear to be wanting.

The three species known to me may be separated as follows :—

Elytra each with two minute basal impressions, the vestiture finer and closely

decumbent, generally intermingled on the elytra with remote erect setz-

which are short and inconspicuous ; body narrower, more punctulate-

anteriorly.

Elytra less inflated, parallel and not more than 14 wider than the prothorax;.

Pennsylvania (Westmoreland Co.).

The description applies to the male, the copulatory spicule

being finely acuminate at tip, but there is very little if any sexual

difference, and no secondary male characters. This species is

closely allied to mzsellus, but is larger, more ventricose and more

convex.

Pennsylvania (Westmoreland Co.).

_ The general habitus of this species is very different from that

of the two preceding and, in connection with the single coarse,

deep and subpubescent fovea at the base of each elytron, would

almost seem to demand for it a separate subgenus. Sexual char-

acters have not been observed.

DELIUS n. gen.

This genus is closely allied to Opresus, but has the scutellum

exposed between the elytra, the legs longer, the hind tarsi moder-

ately elongate with the first four joints equal, short and oblique

at apex, the fifth normal and longer than the two preceding, and

the prothorax bristling on the flanks with stiff but short sete.

The hind coxe extend virtually to the sides of the body and are

extremely approximate, though apparently not quite contiguous.

The single species may be described as follows :—

1. D. robustulus n. sp.—Rather stout, slightly ventricose, very strongly

convex throughout, polished, impunctate, pale rufo-testaceous, the legs and

antennz paler, more flavate and translucent; pubescence short, pale, suberect

dense and intermingled with stiff. inclined spicules on the sides of the pro-

thorax, moderately coarse, even and distinct on the elytra. Head rather small,

slightly wider than long, the eyes well developed, median, convex and promi-

the latter arcuate, wider than the apex; basal angles obtuse and blunt; disk

evenly convex, with two small approximate and confluent fovez in the middle

near the base. Scutellum triangular, flat. Ziytra entire, slightly overlapping

toward tip as usual, rhomboid-oval, narrowly parabolic at apex, widest and

subprominent at the sides just before the middle, scarcely %¢ longer than wide,

214 times as long as the prothorax and barely 144 wider; humeri slightly evi-

dent; humeral plica and impression both very small, the inner fovea more dis-

tinct, subsutural impressions obsolete, the suture finely beaded basally, the

bead expanding and strongly enveloping the scutellum at base. Legs slender,

the femora very feebly clavate, the anterior more distinctly. Length 0.68

No secondary sexual characters are visible in the two speci-

mens before me. The first four ventral segments are equal and

rather short, the last two moderately long.

NELADIUS na. gen.

The single species composing this genus has an elongate and

very convex form of body, the elytra narrowed very gradually to

the extreme base of the prothorax and without trace of humeri,

somewhat as in the subgenus Parascydmus of the Scydmenini ;

they are probably perfectly connate. The head is but feebly in-

clined, the neck wide, with the constriction simple and well ex-

posed, the antenne rather widely separated by the subvertical

front, the clypeus very short and broadly subtruncate at tip, the

labrum short but broad and truncate, and the mandibles moderate

in size, evenly arcuate and with the apices finely aciculate. The

maxillary palpi are of the usual form in the Seydmeenini. ;

The middle and hind coxe are contiguous, the latter trans-

versely suboval, not extending quite to the sides of the body, but

sternum is more pubescent anteriorly and the male sexual char-

acters at the ventral apex moderately developed.

as long as wide, evenly convex, the eyes small, situated before the middle and

down on the sides, feebly convex and not at all prominent, the tempora very

long, only feebly convergent and slightly arcuate behind them to the neck.

Antennxz as long as the head and prothorax, slender, the club rather abrupt,

distinct but not strong ; second joint only slightly shorter and narrower than

the first, a little thicker than the following, feebly obconic, %4 longer than

wide ; third to sixth equal in width ; third distinctly, fourth and sixth very

slightly, shorter than wide ; fifth distinctly longer than wide ; seventh wider

and much longer than the eighth, slightly distorted, rather longer than wide,

2, wider than the sixth ; eighth small and transverse ; ninth and tenth feebly

fusiform, #5 and once wider than the eighth, 44 and % wider than long ;

eleventh short, conoidal, not oblique, as wide as the tenth, only slightly longer

than wide and much shorter than the two preceding. Prothorax as long as

wide, scarcely 14 wider than the head, widest slightly before the middle, the

sides evenly arcuate ; base arcuate, without distinct angles ; disk evenly con-

vex, wholly unmodified. Scutellum small, parallel, longer than wide, ob-

tusely rounded at apex. Zlytra fusiform, gradually and acutely pointed behind,

widest just before the middle, with the sides evenly and strongly arcuate,

nearly % longer than wide, 214 times as long as the prothorax and % wider,

surface strongly, evenly convex, without trace of sutural impressions, the

suture finely beaded in basal sixth or seventh, the bead enveloping the

scutellum. Extreme tip of the dorsal pygidium exposed and broadly rounded.

Legs moderate in length, rather thick, the femora feebly swollen, the anterior

more strongly; hind tarsi nearly 4 as long as the tibiz, the four basal joints

almost exactly equal, the fifth slightly thicker, rather longer than the two

preceding. Length 0.75 mm.; width 0.26 mm.

basal segments are subequal in length. The female is similar to

the male, but has the abdominal vertex broadly and obtusely

rounded, © 3

CEPHENNTINI.

This tribe includes within our territories but one genus, con-

taining about five or six known species, of which three are here

described. These species are assignable to two subgenera.

CEPHENNIUM Miller.

Europe appears to be the headquarters of this very peculiar

and isolated genus, and the species occurring there outnumber

the American about six to one, as far as known at present.

There is no other type of the family approaching very near to-

Cephennium in structure, but Neuraphes may be considered a

connecting bond with the Scydmeenini, and Eutheia with the

Chevrolatiini.

The body is oblong-oval, generally strongly convex, with the

prothorax about as wide as the elytra, having its lateral edges.

acute, the hypomera slightlv concave, and the prosternum very

deeply emarginate through the width of the head and very short.

theia. The head is small, triangular and strongly deflexed, so:

that it is but slightly visible from above, the neck altogether un-

basal when present. COlypeus not separated from the front, the

labrum small, variable in form accordirg to the subgenus. The

mandibles are generally stout, short and arcuate, and a compari-

son of them with those of Leptomastax, shows the most extreme

divergence in form known in the family. Maxillary palpi with

the first three joints nearly as in Euconnini and Scydmeenini, but |

with the fourth small, much more obscure and not subulate, short,

stout and obtuse in form and spongy in structure, projecting

axially from the apex of the third. Antenne very widely separa-

ted, situated at the sides of the head before the eyes and not so

frontal as in most other types of the family; in our species the

club is incrassate and 3-jointed, the joints increasing rapidly in

thickness.

The pronotum is devoid of coarse sculpture, except a feeble

and occasionally subfoveiform depression near each of the basal

angles. Scutellum relatively large, transverse and rounded.

Elytra generally a little wider near basal third or 2 than at base,

the latter fitted closely to the thoracic base throughout the

width, the sides usually more or less acute for a short distance

strongly modified or absent, sometimes taking the form of a long

subgenera as follows :—

Eyes well developed ; labrum small, semicircular; elytra without a long

acute lateral edge behind the thoracic angles but with a longitudinal im-

pressed discal line at base, rounded at tip conjointly, concealing the dorsal

pygidium ; mesosternum with a rounded, impressed and scabrous area an-

Virginia (Norfolk).

The metasternal plate, slightly prolonged between the hind coxe,

is deeply sinuate at the middle of its apex, the sinus almost ex-

actly equal in size and curvature to the apices. The type and

only specimen known to me is possibly a male, as the sixth ventral

is finely punctulate and setulose abruptly in apical half, and the

entire surface of the fifth is similarly but more coarsely asperato-

punctate, the remainder of the abdominal surface being unmod-

fied.

504 Coleopterological Notices, VII.

This species is allied closely to corporosum, but differs in its

narrower form, darker color and still sparser vestiture, more elong-

ate head,thickened hind angles and obliterated foveiform impres-

sions of the pronotum, shorter and more angulate scutellum, longer

sublateral excavated line of the elytra and other characters, among

which may be noted the form of the sinus at the apex of the meta-

sternal intercoxal prolongation, which is here shallower and more

broadly rounded, the apices being narrower and more strongly

rounded.

In corporosum the singular rugose and pubescent rounded de-

pression near the sides of the metasternum, at its anterior margin,.

is quite small, extending through less than 2 of the metasternal

length, while in virginicum it is much larger, extending fully to

the middle.

3. C. anophthalmicum Bndl.—Entomologica Americana, V, p. 194..

Narrowly oblong-oval, parallel, moderately convex, shining, im-

punctate, pale luteo-testaceous throughout, the legs and antenne

concolorous; vestiture moderately distinct, the hairs very short,

closely recurved and mingled with others which are sparse and

more erect, especially toward the tips of the elytra. Head parallel

and nearly straight at the sides in basal half, the eyes wholly want-

ing, narrowed anteriorly, the antenne inserted near the middle, the

prominences very feeble; front moderately prolonged, declivous ant

evenly convex, the margin evenly rounded; mandibles small and

only moderately stout. Antenne about as long as the head and

prothorax, slender, the 3-jointed club stout and very incrassate ;

punctulate ; surface evenly and strongly convex, feebly subex-

planate near the hind angles. Scutellum large, more than twice

hind the middle, the apex subtruncate ; side margins toward base

very acute, the humeral angles denticulate ; subhumeral impres-

sion completely obsolete; each elytron with a single large circu-

lar fovea at the middle of its basal margin, the fovea densely

Spongy-pubescent; suture not modified. Legs short, the femora

rather distinctly clavate. Length 0.9 mm.; width 0.4 mm.

California (Marin Co.). A very small species, apparently

local in habitat and readily identifiable by the absence of eyes and

peculiarities of elytral structure. It is represented before me by

three specimens. Secondary sexual characters are not evident.

This species is somewhat related to the European minimum,

but is larger and differs in its more depressed basal parts of the

elytra, with much more extended acute side margins in continua-

tion of the sides of the prothorax.

ASCYDMINI.

The single species, for which it appears to be necessary to pro-

pose a distinct tribal group, is not distinguished by any great sin-

gularity of habitus, but the palpal differences prevent it from

joining either the Cephenniini or Eutheiini, to the latter of which

it is probably most closely allied.

ASCYDMUS n. gen.

The maxillary palpi in this genus have a form which appears to

be unique in the family, although somewhat remindful of the Chev-

rolatiini, the third joint being oval in outline with its apex ob-

liquely truncate, the truncature being perfectly flat, spongiose in

structure and beset with numerous very short stiff and erect sete;

the fourth joint is wholly obsolete, its function probably being

performed by the terminal setose sensitive surface described.

Aside from this, there seems to be nothing very peculiar about

the type, although certain special structures, present also in Ceph-

ennium, Eutheia and Scydmenus, sufficiently prove its synthetic

nature. There is, for example,a rounded and subimpressed, scab-

506 Coleopterological Notices, VII.

rous and densely setulose surface at each side of the metasternum

anteriorly as in Cephennium. The general aspect of the body,

distant hind coxee and structure of the elytral apices, with the

exposed dorsal pygidium, remind us of Eutheia; but the pro-

sternum is short before the coxze, and the prothorax is of a wholly

different form. The antennz remind us of Scydmenus, except

the very slender pellucid connecting pedicels of the outer joints,

but the nuchal constriction is anteriorly arcuate, the hind coxe

distant, and the prothorax of a different form. All these dispari-

ties, taken in connection with the remarkable structure of the

palpi, force us to regard the single minute representative as the

type of a distinct tribe. Other generic features will be alluded to

in the description given below.

1. A. tener n. sp.—Narrowly suboblong, moderately convex, the elytra

very feebly inflated, polished, impunctate anteriorly, the elytra sparsely punc-

tulate, rather strongly toward base; body rufo-testaceous, the legs and antennz

very pale, flavo-testaceous ; pubescence rather abundant, moderately long,

coarse and pale, suberect but recurved on the elytra, less distinct anteriorly

and with a few longer erect sete. Head well developed, strongly transverse

and triangular, the eyes large, convex, prominent, basal and coarsely faceted,

the tempora extremely short and transverse to the neck, which is wide, the

dorsal constriction feeble and anteriorly arcuate ; vertex not at all impressed ;.

antennal prominences rather marked ; front evenly convex and moderately de-

_ clivous between the antennz to the apex of the clypeus, the latter very

small, not at all developed laterally, subtruncate at apex and with broadly

rounded angles; labrum small, transverse ; mandibles well developed, very

slender at apex. Antenne a little longer than the head and prothorax, slen-

der, gradually and moderately incrassate toward tip ; second joint distinctly

shorter but scarcely narrower than the first, scarcely as long as the next two:

but thicker, cylindric-oval, 1g longer than wide ; third smallest, somewhat

distorted and a little darker in color, slightly wider than long, the

inner side longer than the outer; fourth and fifth subequal, almost as

thick as the second, slightly elongate ; sixth a little shorter and narrower

than the fifth; seventh 4 longer than the sixth, subglobular; eighth a.

ually slightly larger, rather wider than long ; eleventh somewhat thicker,

not as long as the two preceding, obliquely and obtusely pointed ; last two or

three joints mutually connected by extremely slender and translucent stipites.

Prothorax almost exactly quadrate, very feebly rounded and narrowed at apex,

the sides thence subparallel and nearly straight to the base, fully 4 wider

than the prothorax ; surface very faintly impressed transversely in the middle

near the base, also with a small deep and elongate fovea at each side near the

side margin, the latter subacute toward base. Scutellum rather large and con-

spicuous, equilatero-triangular. Llytra scarcely % longer than wide, obvi-

Pennsylvania (Westmoreland Co.) ; Massachusetts (Dracut).

The description is taken from the male, but there are no obvious

secondary modifications; the female is a little more ventricose,

with relatively smaller head and prothorax.

The specimens taken by Mr. Blanchard, under pine bark, in

Massachusetts, do not seem to differ from those sent by Mr.

Schmitt, showing that this remarkable type is not confined to

mountainous districts.

EUTHEIINI,. —

The tribe Eutheiini is allied to the Cephenniini in many of its

structural features, but differs very greatly in the head, which is

here porrect and not deflexed, and borne ona distinct, though ex-

tremely wide, neck, with the constriction exposed. It differs

equally strongly in the form of the prosternum before the coxe,

which, instead of being deeply emarginate and very short, is

rather long and well developed. The genera appear to he three

in number as follows :—

Hind coxe widely separated; body larger in size. ;

Mesosternum broad and perfectly flat; sides of the prothorax acute through-

out the length; nuchal constriction transverse and well marked above, the

vertex not bifoveate; antennz only moderately enlarged toward tip.

Eutheia

Mesosternum strongly carinate; sides of the prothorax acute and margined

only toward base; nuchal constriction more feeble above, anteriorly arcu-

ate and involving two fovese at the base of the vertex; last antennal joint

much inflated and enclosing a large, conspicuous spongy-pubescent cavity.

Veraphis

508 Coleopterological Notices, VII.

I have tried without much success to discover the true form of

the fourth palpal joint in Hutheia and Veraphis ; it is excessively

minute or obscure, and, in some species, the third joint seems to

be slightly oblique at apex, the fourth being a small and obtusely

rounded anchylosed prolongation ; in others it cannot be made out

at all by reflected light, and it would be necessary to detach the

palpus and mount it in Canada balsam in order to discover its

trueform. The palpi are much less developed than in Cephenniini,

rather slender, the second joint shorter than the third, which is

narrowly fusiform, pointed and coarsely pubescent.

EUTHELA Steph.

The species described below agrees in every essential generic

feature with £. scydmenoides of Europe, and is the only true Eu-

theia known to me at present from the American continent. Eu-

theia * is not at all closely related to Cephennium, although the

two have been placed in the same tribal group by recent European

writers. The well developed prosternum before the coxe and

form of the head, are the principal characters which necessitate a

tribal separation.

1. EK. americana n. sp.—Parallel, feebly convex, finely and closely

‘punctured throughout, pale luteo-testaceous, the antennz and legs concolorous,

the head blackish ; prothorax blackish-piceous, paler at the basal and apical

margins ; pubescence extremely short and evenly recurved, quite dense

throughout, coarse, cinereous and distinct. Head much wider than long, very

feebly convex, the eyes large and convex, occupying the entire sides behind

the antenne, finely faceted, the facets convex ; antennal prominences small

‘but distinct ; front between the antennze narrowly parabolic, abruptly vertical

‘to the clypeus, which is very short and truncate ; labrum minute, transverse,

*The particular combination of letters given by Stephens to designate this

genus was Eutheia ; for any subsequent author or set of authors to state that

this was not a proper designation, but that ‘‘ Euthia’’ must be substituted

_ for it, is obviously a kind of impertinent meddling which would produce in-

‘tolerable confusion if carried to its logical—or rather illogical, end. Another

equally flagrant case is the change of Brentus Fabr. into Brenthus. Generic

words are not a part of ordinary language and should not be subject to anv of

the usual rules of etymology, which are always inconstant and capricious ; they

are mere permutations and combinations of letters, used as symbols for genera

simply because numbers, or other serial symbols, do not admit of inter-

polations.

broadly arcuate ; basal angles pronounced, not at all blunt; disk evenly con-

vex, broadly impressed toward the hind angles, with a deep and rounded fovea

at the middle, and another at each side near the base, with a small feeble fovea

intermediate at each side and still more basal. Scutellum small, semicircular.

Elytra % longer than wide, more than twice as long as the prothorax and just

visibly wider ; sides parallel and feebly, evenly arcuate ; apex abbreviated

and broadly truncate ; each elytron with two subfoveate basal impressions, the

outer slightly the larger; suture elevated at base about the scutellum. Ex-

posed part of the dorsal pygidium wider than long, moderately declivous, para-

bolic. Legs rather short, slender, the femora extremely feebly swollen ; hind

tarsi relatively very long, almost as long as the tibie, very slender, with the

four basal joints decreasing very slowly in length. Basal segment of the ab-

domen almost as long as the next three and as long as the sixth, the latter

parabolic. Length 1.0 mm.; width 0.38 mm.

Pennsylvania ( Westmoreland Co.). Mr. Schmitt.

The mesosternum is trapezoidal, flat, impunctate, extending to

the middle of the intermediate acetabula and separated from the

metasternum by a fine subelevated suture; the metasternal pro-

cess has two short, feebly diverging lines from the apex along the

margins of the acetabula. The individual described is a male.

VERAPHIS n. gen.

The head and mesosternum in this genus differ very radically

from the same parts in Eutheia, and, as the name Huthiodes was

applied by Dr. Brendel to a type species described as Huthiodes

lata, which seems to differ generically from his EHuthiodes [| Vera-

phis] cristata, it becomes necessary to give ita new name. The

general form of the body, truncate elytra and exposed dorsal pygi-

dium are nearly as in Kutheia, but the upper surface is more con-

vex, the elytra more inflated, the antennez much more incrassate

at tip and the sculpture or punctuation of the integuments less

pronounced.

ANNALS N. Y. ACAD. Scr., IX, May, 1897.—34.

510 Coleopterological Notices, VII.

The head is borne ona very short and broad neck, the dorsal

constriction being much more feeble than in Kutheia and anteriorly

arcuate, losing itself in a broad general depression at the base of

the vertex, where there are two rather approximate and shallow

fovee. The last joint of the antenne is very large and is deeply

excavated, the excavation being suggested however, in a rudi-

mentary manner, in certain species of Eutheia. The prothorax is

generally transverse, with the lateral edges obtusely rounded, ex-

cept toward base where they become acutely margined and finely

beaded, the prosternum rather long before the coxe exactly as in

Eutheia. The scutellum is well developed, similar to that of

Kutheia, but altogether different from the form assumed in Cephen-

nium, where it is strongly transverse. Other characters of a gen-

eric nature may be noted in the detailed description of cavicornis

and capitata given below.

The species supposed to be assig enable to Veraphis may be indi-

cated as follows :—

Elytra finely punctulate or subimpunctate; pronotum with a generally short

transverse impressed line near the base.

Head not carinate.

These species are all unknown to me in nature except cavicornis

‘and capitata, which are to be regarded as types of the genus;

they are distributed over the entire country from the Atlantic to

the Pacific, although apparently preferring northern latitudes or

high altitudes and appear to be extremely rare, being represented

for the most part by unique examples at present.

Colorado (Garland). This species is apparently represented

only by the unique type in the cabinet of LeConte. If the form

of the prothorax is as stated in the original description given

above, this must be a very singular form, but the tendency of the

author referred to is, as I have several times before had occasion

to remark, to greatly magnify the length of a part in terms of its

width. In the figures accompanying the revision of LeConte

that of ampressa a little wider than long.

It is possible that the remarkable cavity in the eleventh an-.

else about the two specimens before me to indicate the male; in

Pennsylvania (Westmoreland Co.). Mr. Schmitt.

The hind cox are separated by about 2 of their own width,

the metasternum only feebly produced between them and broadly,

feebly sinuate in circular arc throughout the width, the first ab-

‘dominal segment shorter than the next three, the sixth large and

parabolic. The metasternum is finely carinate along the middle

anteriorly, the carina increasing in elevation until it meets the

strong mesosternal keel. The first joint of the hind tarsi is fully

as long as the next two combined.

This species can be readily distinguished from cavicornis by

several strongly accentuated structural differences, which are

however in no way generic or subgeneric in nature. The sex of

‘the unique type is not determinable.

Testaceous, shining, sparsely clothed with suberect yellow

hairs ; head scarcely punctured. Prothorax quadrate, moderately

convex; sides rounded in front, gradually narrowing behind;

hind angles distinct; base truncate with a transverse row of six

large punctures. Elytra moderately convex, coarsely punctured,

The above is the description of Dr. Horn; that of LeConte is

virtually as follows :—

Elongate, ferruginous, shining, clothed with short, sparse and

coarse yellowish pubescence. Head punctulate, feebly impressed.

Prothorax a little wider than long, rounded on the sides, slightly

narrower in front than at the base, which is finely margined at the

middle but without a transverse impressed line; disk punctulate ;

the two large basal punctures [at each side] are confluent, and the

middle one is smaller. Elytra distinctly punctulate. Length

EUTHIODES Bndl.

The characters relating to the palpi, which were given by Dr.

Brendel to distinguish this genus from Eutheia, may be assumed

te be doubtful; it is stated that the third and fourth joints are

united in a thick fusiform body sharply pointed. The antenne

are said to be strongly geniculate, and the posterior coxe very

moderately separated—which is the substance of the entire de:

scription. In the drawing accompanying the description, the hind

body is much inflated, in a way quite foreign to Veraphis or

Hutheia, and the fourth palpal joint is represented as large, conical

and conspicuous, inserted axially in the tip of the third, the latter

short and obconic. The following species is the type :—

1. E. latus Bndl.—Trans. Am. Ent. Soc., XX, 1893, p. 283.

Coarsely, faintly and sparsely punctured at the sides of the

elytra, otherwise impunctate; vertex without impressions, the

pronotum with a median subbasal puncture, a longitudinal elon-

gate fovea near each basal angle, and, between this and the middle

one, two confluent punctures. Elytra 4 longer than wide.

Length 0.66 mm.

Iowa. The non-foveate head, very moderately separated hind

cox and minute size, make it highly improbable that this species

can be congeneric with the cristata of the same author. It may

possibly prove to be a species of Ascydmus, in which case that

name would have to be replaced by Euthiodes, and the tribe

known as the Euthiodiini.

CHEVROLATIINI.

The single known genus of this tribe contains but few species,

exceedingly rare in individuals and distributed perhaps about

equally in Europe, northern Africa and eastern North Amer-

ica; it is not known thus far from the Pacific coast regions of the

American continent. It is a very isolated type, but aside from

the radically different form of the head, seems to have considerable

affinity with the Kutheiini, especially through Veraphis.

CHEVROLATIA Duval.

The body is subdepressed, with truncate elytra and a largely

exposed and feebly declivous dorsal pygidium as in Eutheiini.

516 Coleopterological Notices, VIT.

Head feebly declivous, exserted and borne on an elongate and

rather strongly but not abruptly constricted neck, almost similar

to that of the Lophioderini, and, in an almost similar manner, the

dorsal surface of the neck and basal parts of the vertex are

deeply excavated. Eyes large, convex, median and prominent;

front narrowed and gradually elevated beyond the eyes, the an- —

tenn attached under the tip and approximate at base, monili-

form, gradually and feebly incrassate, devoid of distinct club, and

equally strongly sculptured and finely, though not densely, pubes-

cent from base to apex. Clypeus very short, not visible from

above, broadly and very feebly sinuate at apex, the labrum large,

transverse, circularly sinuate at the middle, the apices more nar-

rowly rounded. Mandibles short, very stout, arcuate, somewhat

angulate externally near the base, the apices acute but not finely

aciculate. Third palpal joint large, stout, finely and denselv

pubescent, the fourth represented by a large and oblique, feebly

convex and spongiose apical truncature; it is attached to the

short and stout second joint by a small, abruptly curved and bulbi-

form peduncle, Labial palpi minute, slightly dilated and strongly ©

setose at apex. Mentum rather small, subquadrate, its surface

strongly convex. Maxillary cardo large and conspicuous, the

lobe elongate, densely setose at tip and more sparsely and

coarsely so along its outer edge. Prothorax strongly carinate at

each side toward base, the prosternum well developed, flat, twice

as wide as long and densely pubescent before the cox, which are

ovo-conoidal and contiguous, their cavities confluent, broadly

open behind and closed by the mesosternum, which is horizon-

tally and shallowly biexcavated for the reception of the cox; an-

terior margin of the double acetabulum cuspid; trochantin com-

pletely wanting. Mesosternum tumid and elevated above the me-

tasternum, slightly prominent along the middle anteriorly but

scarcely carinate, sending a long process between the middle

coxee, the latter conical and rather narrowly separated; side-

pieces tumid and pubescent as usual. Metasternum large,

densely pubescent along its entire anterior margin, finely carinate

along the middle, gradually more strongly anteriorly, the carina

obsolete posteriorly ; parapleurz concealed by the elytra but

turned inward slightly behind to meet the hind cox, which are

small, oval and very remotely separated, more so than in any

other genus of the family, the metasternal edge between them

than the next three together, the latter short; fifth but slightly

longer than the fourth, the sixth elongate, parabolic, longer than

the first. Legs moderate, the hind trochanters small; femora

ling at the basal parts of the head and on the neck. Head a little

longer than wide. Antenne a little longer than the head and pro-

thorax, the basal joint somewhat longer than the next two to-

gether; outer joints gradually wider; eight to ten slightly trans-

verse; basal part of the vertex and the neck deeply depressed,

tinctly longer than wide, fully 2 wider than the head, obliquely

narrowed anteriorly from near the middle, the sides parallel and

straight in more than basal half; disk with a strong longitudinal

carina near the base at the middle, and, on each side, transversely

impressed, the impression interrupted at outer third. Scutellum

small, rounded. Elytra 4 longer than wide, rather more than

twice as long as the prothorax and fully 4 wider; sides feebly sub-

prominent just before the middle; humeri quite evident ; humeral

wide, dilated and enveloping the scutellum at base. Legs mod-

erate in length. Length 2.0 mm.; width 0.63 mm. 7

Georgia (Savannah). It is not possible to state definitely

whether this is the species described by LeConte under the name

amena, from Washington, D. C., and the vicinity of New York

City; the above description is based upon a specimen borrowed

from Mr. Schwarz for the purpose, and has never been compared

carefully with the type; it is apparently a male, as the anterior

- trochanters are obtusely prominent behind. The original descrip-

tion is wholly inadequate, and the statément that the fourth pal-

pal joint is narrow and subulate (Class. Col. N. A., 2 ed., p. 84) is

518 Coleopterological Notices, VII.

unaccountably erroneous. But very few examples have ever been

taken. :

This species apparently occurs only in the low sea-board plains

of the Atlantic coast, and thus far exclusively in the neighborhood

of large cities; the probability of its European origin may there-

fore be an open question for the present. The genus seems, how-

ever, to be represented in Mexico by a species different from any

known in Hurope, and recently described by Mr. Croissandeau

(Ann. Soc. Ent, Wr., 1893, p..281).

LEPTOSCYDMINI.

This tribe, though very limited thus far in extent, is important

from a taxonomic stand point,in the fact that it constitutes a bond

between the ordinary forms of the subfamily, through the Chev-

rolatiini, and the exceedingly isolated Eumicrini which follow.

Its affinity with Chevrolatiini is proved by the truncate elytra,

exposed, flat and declivous pygidium, the latter being however

much more inclined than in that tribe, and by the conformation of

the metasternal side-pieces, these being narrow and concealed by

the elytra but becoming inwardly prominent behind and partially

enclosing the coxe. With the Eumicrini its relationship is in-

dicated by the nearly but not quite vertical pygidium, and slight-

ly arcuate subapical sutures of the abdomen, absence of basal

modifications of the elytra, convex form of body and general

facies. It differs very radically from both the tribes mentioned

in the structure of the front, as explained in the table previously

given.

LEPTOSCYDMUS n. gen.

The body in this genus is narrowly suboval and very convex,

with trunctate elytra and strongly declivous pygidium. Head

well developed, feebly inclined, the neck abruptly and deeply con-

stricted, the constriction perfectly simple and transverse, the eyes

small, anterior and on the sides. Antenne very approximate in in-

sertion, rather short, gradually and strongly incrassate toward tip

but with the last three joints forming a rather indistinctly differ-

entiated club. Clypeus flat, porrect, moderate in length, the lab-

rum small, short and transverse. Mandibles moderate in devel-

opment, dentate within as usual, the portion between the tooth

and the apex rather slender, feebly arcuate, very gradually and

finely pointed and apparently extremely minutely and feebly ser-

rulate within to near the apex. Maxillary palpi very moderate in

size, the third joint rather slender, ovo-obconic, with the terminal

axial button small and obtuse, the labial palpi very minute. Men-

tum large, flat, polished and sculptureless, trapezoidal. Protho-

rax subcordate, strongly convex, feebly foveate near the base, the

prosternum well developed and pubescent before the coxe. Scu-

tellum excessively minute but present in both species, only visible

under high amplification. Hlytra oval, strongly convex, devoid

of the feeblest trace of basal impression, fitted evenly and closely

against the broadly arcuate base of the prothorax, very narrowly

overlapping posteriorly, the apical truncature nearly straight and

anteriorly oblique sutureward, the sutural angles extremely mi-

nutely denticulate. Mesosternum very strongly carinate, the

middle coxse narrowly separated; hind coxe distinctly but not

remotely separated, the abdominal process truncate ; first abdomi-

nal segment not as long as the next three, the last two rather

short. Legs moderate in length, the femora slightly clavate ;

hind tarsi much shorter than the tibiz, with the first joint not

quite as long as the next two; second to fourth subequal, the fifth

as long as the first two, the four basal joints oblique at apex;

claws extremely slender and strongly arcuate.

deep perforate fovea at each side of the middle near the base,

and another more minute and lateral. Elytra almost } longer than

Pennsylvania (Westmoreland Oo.). The description is derived

from the male, but the female is nearly similar, having the head a

little narrower and as long as wide, more triangular, the sides be-

hind the eyes more feebly arcuate and the small frontal cusp not

tumid, the antenne fully as long but not quite so stout, and the

elytra just visibly shorter and more inflated; there is but little

sexual difference in the eyes. In the male the last two ventral

segmentsare a little longer than in the female, the fifth in the lat-

ter not being longer than the fourth; but in both sexes they are

perfectly simple and unmodified, the sixth evenly rounded be-

Pennsylvania (Westmoreland Co.). Mr. Schmitt.

The male described above differs conspicuously from the female,

the latter having the head narrower, more parallel, rather longer than

wide, equally pubescent throughout, and not concave behind the

truncate frontal margin, which is only very feebly and obtusely sub-

prominent at the middle; the eyes are nearly as in the male, the

antenne a little more slender, with the basal joint not quiteas long

and the fifth joint not evidently larger, but otherwise similar, and

the elytra are very slightly shorter and more inflated. In the

male the fifth ventral segment has a deflexed and cuspid apical

margin, the cusp obtusely angulate and finely pubescent, and the

sixth has a large rounded median excavation, which is feebly con-

cave, glabrous and polished, with its edges prominent at the sides

posteriorly but not at the middle of the apex. In the female the

last two segments are perfectly simple, the fifth not longer than

the fourth and the sixth a little longer, evenly and broadly para-

bolic at apex.

EUMICRINI.

Within this tribe are included forms which differ profoundly

from all other Scydmenidzx in the elongation of the posterior

trochanters, in the possession of a large vertical and convex

pygidium, and in having the segments and sutures of the abdo-

men arcuate. All of these characters are preéminently and essen-

tially pselaphidous in nature, and show that the Eumicrini make

a closer approach to the Pselaphide than any other known types

of the present family. The Eumicrini include also some of the

largest and most specialized forms of the family, having in fact

very much the same relationship with the ordinary Scydmenide

subulipalpi, that the Ctenistini and Tyrini bear to the Bryaxini,

for example. |

The genera are moderately numerous, and have been involved

in considerable ambiguity hitherto. In the recent European cata-

logue of Heyden, Reitter and Weise, there are included under the

head of Scydmeenus, the subgenera Microstemma of Motschulsky,

having for its type tarsata Mull, Hustemmus of Reitter, having as

types antidotus and some other species, none of which are before

me now, and Scydmenus 2n sp., with rufus Mull. and hellwigi

Fab., for its types among others, and having for a synonym Cho-

lerus Thoms. Eumicrus is alleged to be a synonym of Scydme-

nus in its comprehensive sense.

Now the most obvious inconsistency in this arrangement comes

from the fact that the subgenus Scydmeenus of Reitter, contains

at least two perfectly distinct genera, one having for its type

rufus, the type of Cholerus Thoms., with the side-pieces of the

metasternum completely covered by the elytra and not approach-

ing the hind coxe, and the other represented by hellwigt, which

is constituted throughout exactly like our zimmermanni, with

distinct met-episterna, which partially enclose the hind coxa. I

would propose, therefore, the following scheme for generic types,

which would seem to be sufficiently exact and impartial.

EustEmMMus Reit.—type antidotus Germ.

Evumicrvus Lap. (syn. Microstemma Mots.)—type tarsatus Mull.

CHoLERUS Thoms.—type rufus Mull.

For the reasons stated above, hellwigi and zimmermanni, with

congeneric species, must receive a new name, and it is probable

that the Australian Heterognathus, of King, will prove to be valid

also.

Coleopterological Notices, VII. 523

Our genera are three in number and may be thus defined :—

Met-episternum distinct, partly enclosing the hind coxz ; prothorax oval, the

prosternum moderately developed before the coxe ; hind body moderately

inflated.

Body stouter ; scutellum present between the elytra though minute; first

joint of the hind tarsi only moderately elongate.................. Eumicrus

Met-episternum entirely covered, the hind coxe wholly enclosed by the ster-

- num and abdomen ; prothorax narrow, strongly conic, the prosternum much

longer before the coxee ; hind body greatly inflated............... Ceramphis

The species assigned below to Eumicrus coincide completely in

habitus and generic structure with the European tarsatus, the an-

terior tarsi being generally dilated in the male in the same man-

ner. Humicrus and Acholerops are confined to the Atlantic and

Sonoran provinces of our fauna, while Ceramphis is purely

Sonoran.

EUMICRUS Lap.

Body stout and very convex, with entire and conjointly rounded

elytra, which are generally impaosaed at base but without trace of

fovere. The head is large and thick, borne on avery strongly con-.

stricted neck, the constriction appearing in vertical profile as a

deep and narrow cleft at each side, simple and transverse above.

Kyes well developed and anterior; front narrowed and slightly

prolonged in the middle, the antenne quite approximate at base,

long and well developed, rather thick, with the basal joint some

what more elongate than usual, and the apical joints forming

the 3-jointed, incrassate and very aieiehe and densely pubescent

club characteristic of the tribe; funicle strongly reflexile in the ex-

cavated apex of the basal joint. Clypeus simple, porrect, truncate

and moderate in length, the labrum short, transverse, bearing an

apical series of long stiff setze, and with a median indentation on

the disk. Mandibles quite well developed, the median tooth of

the right acute, inclined and well developed, that of the left

being short and hollowed in saginata. The maxillary palpi are

long and well developed, the second joint arcuate, third longer

and narrowly obconic, very finely and densely pubescent, the

fourth minute, rigidly and axially attached within the apex of the

third, obtuse and similarly densely pubescent, the labial with the

first joint small, the second elongate and cylindric and the third

short and slender, inserted obliquely in the apex of the second.

Mentum trapezoidal, flat, with the basal angles reflexed.

The prothorax is rather long, subparallel and generally

broadly rounded at the sides, the latter oblique and straight or

nearly so toward base, the pronotum usually with two small foveze

at each side near the base, the prosternum moderately long before

the coxz, pubescent but with a median triangular glabrous area

bordering the acetabula, the coxe large and conovoidal. Middle

coxee large, very approximate, separated only by a narrow lami-

nate carina, the trochanters moderate in length, stout. Posterior

coxe rather widely separated, oval, extending only to the wide

met-episterna, which are defined by a very coarse and excavated

suture ; trochanters long, cylindric and swoilen internally toward

apex. First ventral segment almost as long as the next three.

Legs long, the femora very strongly clavate in apical half or more;

tibize straight ; tarsi slender, the anterior incrassate or dilated to-

ward base.

Our species may be briefly outlined by the foliowing characters:—

Front more broadly and feebly prominent between the antenne; basal joint:

of the latter moderate in length; elytra more distinctly impressed at base,

with more evident humeri; pubescence denser, moderately long and dis-

tinctly recurved on the elytra; head not more pubescent at base; body

.generally darker in color.

Larger species, more elongate-oval, never less than 2 mm. in length.

Head more strongly transverse, obsoletely elevated longitudinally in the

middle toward base; pronotum densely punctured toward base.

The two principal subdivisions indicated above are almost sub-

in habits. The species are rather closely allied among themselves

but appear to be distinct as defined above. The male has the

sixth ventral segment longer than the female as a rule.

South Carolina.

The abdomen is minutely and rather densely punctulate as us-

ual. In the single individual before me the sixth segment is about

as long as the first and the type is therefore a male; the anterior

tarsi appear to be strongly dilated toward base.

This species differs greatly from grossus in general habitus, the

elytra being much longer, more pointed, rather less convex and

with much less evident humeri; it also differs in its slightly

smaller and less transverse head and in numerous other details of

structure.

3. Eu. vestalis Csy.—Cont. Descr. Syst. Col. N. A., II, p. 85.

The female of this species, which has been described in detail

at the above reference, differs very much from the male in facies,

and in the outline of the head and prothorax. In the female the

head behind the antenne is about 4 wider than long, with the sides

subparallel and very feebly arcuate, while in the male it is only

slightly wider than long, with the sides convergent and circularly

arcuate to the neck. In the female the prothorax is broad, glo-

bularly convex, not longer than wide and much wider than the

head ; in the male much narrower and nearly cylindrical, only a

little wider than the head, distinctly longer than wide, 4 as wide as

near apical third, the sides convergent and nearly straight to the base from be-

fore the middle; disk very remotely and feebly punctulate toward base, with

two large and deep foveze at each side, the inner transversely oval and deepest

under its posterior margin, the outer circular. Elytra % longer than wide,

not much more than twice as long as the prothorax and nearly 24 wider, oval,

rather obtusely rounded behind, widest and more prominently rounded at the

sides well before the middle ; humeri distinct, tumid above, the basal im-

pression rather large and distinct ; subsutural impressions very long but feeble,

the suture not modified ; disk not distinctly punctulate. Pygidiwm very con-

vex, equilatero-triangular, the apex rather broadly obtuse ; disk not punctate

toward base, with shorter, coarser pubescence along the lateral margin near the

apex. Legs long, the femora gradually clavate ; hind tarsi with the basal joint

nearly 14 longer than the second ; two to four exactly equal in length, the

fourth as long as the two preceding. Length 2.2 mm.; width 0.78 mm.

Tennessee.

The sixth ventral in the unique type is as long as the first, and

the sex of the individual described is therefore probably male, but

the anterior tarsi are only slightly stouter toward base and not

dilated. |

As usual throughout, the scutellum is small, narrow, elongate,

tumid and rather deep-set, differing greatly from the evenly flat

form seen in other tribes.

Arizona (Tucson).

The single specimen, which I took a few years since, indicates a

species somewhat allied to vestalzs, but differing in its smaller and

more quadrate head, shorter, broader and more depressed elytra,

and, especially, in its abruptly and not gradually clavate femora.

The type has the sixth ventral a little shorter than the first as in

the male of vestalis, but the anterior tarsi are not dilated appre-

ciably ; in the female of the latter the sixth segment is not much

more than half as long as the first, and is more emarginated by

the tip of the pygidium.

Florida (Crescent City and Enterprise). Mr. Schwarz.

This species, which is described above from the female, is closely

allied to motschulskii, but differs in its much less obese form, rela-

tively more inflated hind body, and especially in its much nar-

rower and more rapidly incrassate antennal club. A male before

me labeled ‘‘ South Carolina ” does not seem to differ specifically ;

it has the anterior tarsi strongly dilated toward base.

8. Eu. longicollis n. sp.—Moderately stout, rather strongly ventricose,

polished, impunctate, uniformly dark rufo-testaceous, the legs and antennz

concolorous ; pubescence rather sparse, short and inconspicuous anteriorly,

long, erect and bristling on the elytra. Head behind the antennz as long as

wide, parabolic in outline from the anterior margin of the eyes around the

base, the eyes moderate in size, not at all prominent ; upper surface more con-

vex behind, finely and rather closely punctulate anteriorly, the pubescence

short and decumbent, becoming longer and erect posteriorly, where there is a

Very readily distinguishable by the rather long and narrow pro-

thorax, widest behind the middle, somewhat slender and very

the anterior tarsi are slender and only just visibly thicker toward

base.

Central Illinois. Mr. Webster.

The description is taken from a specimen having the sixth

ventral much shorter than the first; another, which has this seg-

ment distinctly longer than the first, has the head visibly less

transverse and more strongly narrowed behind; I regard the lat-

ter as the male, and, in this example, the anterior tarsi are feebly

dilated toward base.

This species differs from longicollis in its much shorter pro-

thorax, widest near the middle and less narrowed anteriorly, in

its slightly stouter antenne and still more inflated hind body ; it

is however very closely allied both to that and to the following

species.

10. Eu. Ssagimatus n. sp.—Stout and rather strongly ventricose, pol-

ished, impunctate, the body, legs and antennz very pale flavo-testaceous

throughout ; pubescence short, stiff and distinct on the head, sparse and longer,

but very inconspicuous on the pronotum, long, sparse, erect and bristling on

the elytra. Head moderate in size, distinctly wider than long behind the

antenne, circularly rounded and convergent at the sides from the eyes to the

neck ; eyes moderate in size, not at all prominent; upper surface convex,

minutely and feebly but closely punctulate, the frontal projection densely and

distinctly punctato-scabrous. Antenne fully 3% as long as the body, the club

narrow, long and feebly incrassate ; basal joint much stouter than the follow-

ing, enlarged and deeply excavated at apex, barely twice as long as wide and

scarcely longer than the next two; second to fourth subequal, only slightly

longer than wide ; fifth feebly obconic, not more than 1g longer than wide, a

little thicker than the preceding but as wide as six to eight, which are short,

oblique and deeply excavated within at apex as usual; ninth as long as the

two preceding and 4g wider, not longer than wide ; tenth a little thicker, sub-

oval with truncate base, rather longer than wide ; eleventh long, gradually

and obliquely pointed, rather thicker, barely as long as the two preceding.

Prothorax barely as long as wide, nearly 4g wider than the head, widest and

more strongly rounded well behind the middle, the sides thence rather

broadly rounded behind ; humeri and basal impression nearly obsolete ; sub-

sutural impressions slightly evident toward base. Pygidium triangular, rather

wider than long, feebly rugulose toward base. Legs rather short and stout,

the femora very strongly and abruptly clavate ; basal joint of the hind tarsi

4¢ longer than the second. Length 1.8 mm.; width 0.75 mm.

Iowa (Iowa City). Mr. Wickham.

The shorter and stouter form of the body, with the prothorax

inflated and widest behind the middle, and smaller head, will dis-

tinguish this species from ochreatus. The single specimen before

me has the sixth ventral rather longer than the preceding three

combined when measured along the median line, and is doubtless

a male.

11. Eu. cruralis n. sp.—Stout, the hind body strongly inflated, polished

and impunctate, pale rufo-ferruginous throughout, the legs and antennz con-

colorous; pubescence sparse, short and coarser on the head, long, erect and

bristling on the elytra. Head behind the antennez scarcely visibly wider than

long, the eyes well developed but not prominent, the sides strongly conver-

gent, broadly and evenly arcuate to the neck, which is 14 as wide as the head;

upper surface convex and broadly tumid behind, minutely, sparsely punctu-

late, except in the middle toward base, more distinctly punctate on the

median prolongation of the front. Antenne rather more than 1% as long as the

body, the club long, slender and feebly incrassate; basal joint long, cylindric,

more than twice as long as wide, a little longer than the next two and much

thicker, excavated above at apex but not grooved; second obconic, a little

longer than the fourth but not thicker, %¢ longer than wide; third and fourth

1g, fifth scarcely ?¢, sixth 14, longer than wide; seventh not quite as long as

wide, the upper twice as long as the lower side; eighth also very oblique at

tip, much wider than long; ninth distinctly shorter than the. two preceding

and only 1g wider, a little longer than wide; tenth still thicker, similar in

form, slightly elongate; eleventh long, not thicker than the tenth, not quite

as long as the two preceding, gradually and obliquely pointed. Prothorax

narrow, scarcely 14 wider than the head, slightly elongate, the sides parallel

and broadly rounded, widest at the middle; apex much narrower than the

base; disk finely rugulose near the basal margin and with two small and

feeble subbasal foveze at each side. Elytra 1g longer than wide, twice as long

as the prothorax and fully twice as wide, widest at the middle, strongly and

obliquely narrowed to the base of the prothorax, broadly rounded behind;

humeri and basal impression nearly obsolete; subsutural impressions feebly

visible near the base. Pygidiwm triangular, much wider than long, sparsely

punctulate and minutely, transversely reticulate toward base. Legs stout, the

femora strongly and abruptly clavate, the posterior with an obtusely triangu-

lar tooth on the outer edge near the trochanter; basal joint of the hind tarsi 14

Length 2.0 mm; width 0.8 mm.

Central Iliinois. Mr. Webster.

The unique type has the sixth ventral segment large, nearly as

long as the four preceding and longer than the first; judging by

this and the narrow head, with rapidly converging sides behind

the eyes, it is undoubtedly a male, but the femoral tooth is never-

theless probably common to both sexes; the anterior tarsi are

only very feebly enlarged toward base. The species is allied

closely in general appearance to the others of this section, and

especially to longicollis.

ACHOLEROPS n. gen.

This genus is closely allied to Eumicrus, but differs constantly

in its narrower form of body, obsolete or very indistinct sub-

basal fovese of the pronotum, obsolete basal impression of the

elvtra, broader and less deeply constricted neck and complete ab-

sence of scutellum, the latter being minute, but exceedingly per-

sistent in all of the rather numerous species of Eumicrus. It also

differs in having the triangular glabrous plate adjoining the an-

terior coxe obsolete or very minute and of a different character,

the hind tarsi more elongate, with the basal joint as long as the

next two, and the anterior slender, but slightly affected sexually

and then only in the basal joint. The middle coxe are narrowly

separated by a feebly elevated and obtuse carina, the posterior

rather widely separated, the met-episterna narrower than in

EKumicrus, but delimited by the same very coarsely excavated

suture, and the hind trochanters, although undoubtedly elongate,

are less distinctly so than in Eumicrus and are more swollen

within. In other characters, including the general habitus of the

body, antennal structure, form of the front, palpi and pygidium,

the two genera are virtually similar, though the third palpal joint

is rather more fusiform and less conical, and only 2 to 4 longer

than the second in Acholerops.

The known species of our fauna are as yet few in number, and

may be discriminated by the following general characters :—

Hind tarsi very long and slender; elytra without trace of basal erosion; body

The first of these species differs very greatly from the second

in facies and in some structural characters ; other forms will be

discovered, as the species of Acholerops are much smaller and

more obscure, as a rule, than the components of Eumicrus.

Michigan (Ann Arbor) and Pennsylvania. The description

given above is drawn from the original type of punctatus. A

large series from Pennsylvania agrees well, and in this series I

can only distinguish the male from the female by the broader and

somewhat larger head and very slightly stouter form; both sexes

seem to have the sixth segment very large and longer than the

preceding four, and there is generally a small apical and more

densely pubescent erosion. The anterior tarsi are rapidly stouter

toward base and densely papillose beneath. 3

If this species is correctly identified, I cannot understand the

statement twice made in the original description—“ coleopteris

confertim punctulatis,” and “coleoptera . . . ‘subtiliter

punctata ”—when the elytra are unusually strongly punctured ; it

was described by Schaum from a Carolina specimen sent by Zim-

mermann. Motschulsky states (Htudes Ent., 5, 1856, p. 11) that

the S. zimmermanni of Schaum, lives with ants under the bark of

old trees, where he took it near Atlanta, Georgia.

2. A. retrusa n. sp.—Moderately stout and rather ventricose, polished,

the head impunctate ; pronotum excessively finely, sparsely punctulate and

not more distinctly so toward base, the elytra sparsely and very minutely

punctate ; pubescence rather sparse, nearly even, short and subdecumbent.

Head quite distinctly wider than long behind the antenne, with the sides

perfectly parallel, evenly and broadly arcuate throughout, rounding subtrans-

versely for a short distance to the neck, which is about % as wide as the head;

eyes small and not prominent ; surface feebly and evenly convex, the scanty

hairs arranged subtransversely; antennal prominences not distinct, the frontal

lobe short and broadly rounded. Antenne barely 44 as long as the body,

slender, the club rather rapidly incrassate ; basal joint narrowed at base, fully

twice as long as wide, distinctly thicker than the second but only about 1g

longer, the second very slightly thicker and much longer than the third, feebly

obconic ; second nearly once, third and fourth equal, %, fifth 24, sixth 4,

longer than wide ; six to eight oblique at apex ; seventh and eighth subequal,

scarcely wider, much shorter than wide ; ninth rather small, barely as long as

the two preceding and only 14 wider, obconic, slightly elongate ; tenth much

larger, longer than the ninth and 44 wider, obtrapezoidal with rounded sides,

about as long as wide; eleventh only just visibly thicker, oval, gradually

pointed, much shorter than the two preceding. Prothorax rather longer than

wide, more than % wider than the head, widest and evenly rounded laterally

at apical third, the sides thence oblique and straight to the base ; surface

strongly convex, very feebly and transversely impressed near the basal margin,

with two minute and very approximate subbasal foveee near each side. lytra

subrhomboidal, strongly convex, scarcely more than 1g longer than wide, a

humeri not evident, the tumid mes-episternum visible in the reéntrant angle,

as is frequently the case throughout the family ; disk even, the base fitted

closely against the arcuate base of the prothorax, with a small erosion at the

middle of the basal margin of each. Pygidium small, feebly convex, equilatero-

triangular with rounded apex, finely punctulate and rugulose, somewhat

oblique, not vertical, and visible from above to some extent. Legs moderate

in length and rather slender, the femora quite feebly and gradually clavate ;

hind tarsi very much shorter than the tibie, with the first joint only moder-

ately elongate but equal to the next two. Length 1.0-1.2 mm.; width 0.4—

0.48 mm.

Pennsylvania (Westmoreland Co.). Mr. Schmitt.

The male described above has the anterior tarsi distinctly di-

lated toward base and papillose beneath, and the sixth ventral

segment large, longer than the four preceding, with the apex

rather strongly rounded. The female is somewhat smaller than

the male, with shorter and more slender antenne, and relatively

shorter and still more obviously rhomboidal elytra which conceal

the pygidium, the latter more vertical; the sixth ventral is very

much shorter than in the male, and the anterior tarsi are slender

and completely undilated. The species appears to occur in con-

siderable abundance.

CERAMPHIS n. gen.

The single species representing this genus is one of the most

remarkable types of the family, and differs to an extraordinary

degree from Eumicrus and Acholerops, the metasternum extend-

ing in one large unbroken expanse from side to side, without

trace of the met-episternal suture which is so marked and strongly

developed a feature in those genera; this is all the more remark-

able when we consider the extremely short and inflated hind body.

It also differs profoundly from all other types of the Eumicrini

in having the prothorax geometrically conical, with a much larger

extent of prosternum before the coxe, and in the abruptly in-

flated hind body alluded to, but in the elongated posterior

trochanters, short abdomen with arcuate segments, large, vertical

and convex pygidium and structure of the front and palpi, it is

similar, and therefore cannot be separated tribally; in this connec-

tion, it should be stated that in the absence of a met-episternal

suture the genus is quite homologous with the Huropean Cho-

lerus rufus, although having no special resemblance otherwise

with that aberrant ally of Eumicrus and Acholerops.

Coleopterological Notices, VII. 539

The head is borne on a deeply constricted neck, the constric-

tion transverse and simple, the upper surface strongly tumid in

the middle toward base, the eyes anterior; front truncate, with a

feeble median projection, the antennal cavities large, separated by

a narrow and entire lamina, the clypeus below rather advanced,

broad and conical, approaching the form distinctive of Leptomas-

tax. Labrum short, transverse, feebly arcuate at apex, not im-

pressed, the mandibles moderate, evenly arcuate, acute at apex,

each with a slender median tooth internally, that of the right only

slightly the longer. Antenne approximate, the basal joint

moderate in length, excavated above at apex for the reflexion of

the funicle, the club elongate, 3-jointed and finely pubescent as in

Eumicrus. Maxillary palpi long and slender, clothed sparsely

with coarse erect setz and not minutely pubescent, the third joint

longer than the second, narrowed gradually toward base, the

fourth minute, obtuse, inserted rigidly and axially within its apex,

the last joint of the labial slender, oblique and subulate. Mentum

trapezoidal and concave, with two discal setz as usual. Prothorax

conical, without trace of lateral margin or subbasal fovese or im-

pression, Scutellum distinct, triangular, tumid as in Eumicrus but

broader. Elytra without basal fovee,entireand broadly rounded

at apex, the pygidium large, convex and vertical. Prosternum

very elongate, shining and glabrous before the coxe, with a

densely and longly setose fovea at the anterior margin of each,

deeply and circularly emarginate at apex. Middle coxe very ap-

proximate, the mesosternum between them apparently not carinate.

Hind coxe rather small, transversely oval, mutually separated by

rather more, and each from the sides of the body by rather less, than

their own width. Abdomen very short, the basal segment much

longer than the next four, which are extremely short. Legs well

developed, the hind trochanters much elongated and feebly obconic,

the femora distinctly but gradually clavate, the tarsi short and

stout, gradually thickened toward base throughout, the anterior

not particularly dilated in the male.

Head behind the antenne 2 wider than long, the eyes well devel-

oped, convex and prominent; sides behind them converging and

rounded to the neck; surface strongly tumid and elevated toward

the median line, especially toward base. Antenne #? as long as

crassate; basal joint scarcely 4 longer than the second and only

slightly thicker, 22 times as long as wide; second subcylindric, 4

longer than wide, almost as long as the next two, which are

obconic, slightly longer and shorter than wide respectively ; fifth

dilated, wider than long, angulate at the external apical angle

and deeply excavated at the apex externally; next three joints

subequal, not wider than the fourth, scarcely modified, wider than

long ; ninth very feebly obconic, not quite as long as the two pre-

ceding and scarcely more than 4 wider, fully + longer than wide ;

tenth obconic, as long as the two preceding and fully 4 thicker

than the ninth, nearly 4 longer than wide; eleventh suboval,

thicker than the tenth but less than 4 longer, obliquely pointed

thorax evenly conic, as long as wide, apex # as wide as the base,

the latter equal in width to the head; sides perfectly straight

throughout the entire length; disk transversely and slightly

tumid before the basal margin toward the middle. Elytra about

as long as wide, # longer than the prothorax and a little more

than twice as wide, widest and more strongly rounded at the mid-

dle; humeri rounded but distinctly exposed at base, not tumid

above; disk with a large shallow impression at the base of each,

evenly convex and not otherwise modified. Pygidium impunctate,

pubescent, equilatero-triangular, obtuse at apex. Legs rather

long, the femora gradually and moderately clavate; basal joint of

the hind tarsi barely as long as the next two, the apex of the

tibize with a fringe of spinules. Length 1.5 mm.; width 0.73 mm,

California (Los Angeles) and Arizona. Apparently not rare;

the description is taken from the male, but the sixth ventral is

not much elongated and is very much shorter than the first; in

the female the antennz are probably simple. The most impor-

tant structural characters of this species were overlooked by Dr.

Horn, and the fourth palpal joint is not subulate as stated by that

author, but the figure (1. c., plate) is quite accurate in outline.

Coleopterological Notices, VII. | 5AL:

Cae:

This subfamily i is but. scantily represented in the United States

by a single genus, containing species which are moderate or small.

in size, and contrasting greatly in this respect with the large and

vigorous members of the genus Clidicus inhabiting Java and ad-

jacent warm regions of the world, or even with Mastigus, which is

well represented in southern One ope. The fourth palpal joint |

varies in structure even more than in the Scydmeenine, from the

fused and indistinct form of Leptomastax, to the. large, oval and

nearly free form of Mastigus, these types of structure affording

good criteria for tribal separation. The three tribes represented ;

before may be distinguished by the following characters :—

Last joint of the maxillary palpi. very indistinct, forming an oblique, convex,

feebly and excentrically pointed surface at the apex of the third, with which

it is completely fused, the two forming a stout and evenly suboval mass,

which is very minutely and densely pubescent; prosternum greatly developed

before the coxe; elytra striato-punctate.............ceceeeeeeeees LEPTOMASTACINI

Last joint small and conical but distinct, rigidly inserted within the tip of

the third, with which it is broadly fused, not oblique or only feebly so; pro-

sternum moderately developed before the coxe; elytra striato-punctate.

2 CLIDICINI

Last joint large, oval, wider than, and almost as long as, the third, with

which however it is united by a rather broad and subanchylosed base; pro-

sternum moderately developed before the coxe; elytra confusedly wanabned:

| MASTIGINI

The first and third of these tribes are purely European and are

introduced merely for comparison ; the Mastigini lead toward some

probably extinct form in the gradual development and isolation

of the fourth palpal joint. The association of Leptomastax and

Ablepton with Mastigus in a single tribal group, as proposed in the

recent catalogue of Heyden, Reitter and Weise, is not philosophic

or in accordance with the radical nature of the palpal differences.

Leptomastax is devoid of all trace of eyes, having the head

large, rounded and depressed, the clypeus forming an extremely

short transverse piece between the front and the large, corneous

and emarginate labrum, and the mandibles extremely long, slender

and evenly arcuate, while Ablepton has the head very small and

the mandibles much less developed, the eyes being present but ex-

tremely rudimentary, consisting of a single small convex facet.

Mastigus has the body very strongly convex, with the head longi-

tudinally impressed, the eyes well developed, the basal joint of the

antenne greatly, and the second also notably, elongate, and the

labial palpi stout and subinflated; it is one of the most isolated

types of the family and should undoubtedly form a distinct tribe.

The genus Hecotus of Sharp (Biologia Centrali-Americana, II,

pt. 1, 1887, p. 70), is sufficiently abnormal not only to render its

affinity with Clidicus very doubtful, but even to suggest some

question of its being a member of the Scydmenide. Nothing

further will be necessary than to invite attention to the abdomen,

which is said to have five segments, and to the scutellum, which

is shown distinctly in the drawing through unmentioned in the

description. There is generally no distinct trace of a scutellum

between the elytra in the Clidicine, and no scydmeenid is known

to me having less than six perfectly formed ventral segments.

CLIDICINI.

The genus Clidicus and related forms are much less abundant

in subarctic faunal regions than the Leptomastacini, but Papusus

will probably contain a limited number of species distributed

through the arid regions of Mexico. It is not possible to present

a table of genera on account of the paucity of material.

PAPUSUS n. gen.

The body in this genus is elongate-oval in form and rather con-

vex, the head large, borne on a deeply and simply constricted

neck, which is rather broad, the eyes well developed, on the sides

at or just before the middle, feebly convex, not prominent and

consisting of very coarse and convex lenses, the antennz inserted

in small and remotely separated fovese at the summit of the long

and feebly declivous front, just before the middle of the length;

they are strongly geniculate, with the basal joint elongate, not

quite equal to the next three in length, and the remainder are

feebly and gradually incrassate to the tip, with but the feeblest

trace of a 5-jointed club. The clypeus is short, transverse, con-

tinuing the feeble slope of the front and separated therefrom by a

straight transverse suture, the apex transversely and very broadly

truncate, the labrum much narrower, short, transverse, polished,

corneous, emarginate at apex and bearing only some six long setze

in a transverse and arcuate subapical series. Mandibles moder-

ately large, very stout, straight toward base, gradually bent

toward apex. Maxillary palpi long and rather slender, well de-

veloped, the second joint feebly bent, gradually enlarged and

rather coarsely pubescent, the third distinctly longer, narrowly

and evenly obconic, minutely and densely pubescent, the fourth

rather more than 4 as long as the third, conic, not quite as wide

at base as the tip of the third and similarly pubescent; the labial

palpi are moderate in length, slender, the second joint moderately

elongate and feebly fusiform, the third slender, oblique and subu-

late, the second with a short and erect seta projecting from the

side of the apex, suggestive of the enormously developed spines

of Leptomastax. Mentum transverse, flat, trapezoidal, polished

and glabrous. Gular sutures separated rather widely at the neck,

very rapidly and arcuately diverging anteriorly.

The prothorax is strongly obovate, broadly rounding at base,

without lateral margin or subbasal modification of any kind, the

prosternum before the coxe flat, about twice as wide as long,

circularly emarginate at apex and finely, uniformly and moder-

ately densely pubescent, the margins of the acetabula minutely

elevated, the cox stout and conovoidal. Elytra elongate-ellipti-

cal,punctato-striate, entire, apparently connate,not at all impressed

at base, the scutellum not visible. Mesosternum large, not cari-

nate, widely enclosing the coxe at the sides, the side-pieces flat

and not tumid, the coxe very large, globular, extremely approxi-

mate. Metasternum very short, the episterna triangular, dis-

tinctly exposed, becoming very widely so behind and almost, but

not quite, attaining the coxez as in Leptomastax, the hind coxe

very small, widely separated, globular, with a short truncate ex-

tension, the trochanters small and triangular. Abdomen very long

and well developed, broadly convex, almost twice as long as the

remainder of the hind body, with the sutures straight and trans-

verse, the first segment almost as long as the next three, the last

as long as the preceding two and narrowly rounded, entirely en-

closed within the elytra. Legs moderate in length, rather stout,

the femora strongly and rather gradually clavate, the tibiz straight,

densely pubescent, the anterior tarsi slender, gradually thicker

toward base, the intermediate a little longer but thick, cylindric and

very minutely, densely pubescent, the posterior much longer and

very slender, filiform, 2 as long as the tibie, the four basal joints

decreasing almost evenly, the first 2 longer than the second;

claws moderate in length, feebly arcuate and very minutely setose

or pectinate within throughout the length.

544 Coleopterological Notices, VII.

The resemblance of this genus to Leptomastax is evident prin-.

cipally in the elongate form and peculiar habitus of the body, in’

the structure of the legs, hind coxe, metasternum and its para-

pleurze, and in the mode of antennal insertion. In Ablepton the an-.

tenn are inserted in much larger and more perpendicular frontal

cavities, and the clypeus and labrum, as well as the mandibles, are

altogether different from the corresponding parts in Leptomastax.

Papusus differs from Clidicus not only in the much smaller size of:

its species, Clidicus grandis being some 7 mm. in length, but appar-.

ently in the more elongate second antennal joint and well devel-

oped eyes. | |

California (Palm Springs, Colorado Desert).

A single specimen of this interesting species was alee by Mr.

H.C. Fall under astone; its sexisnotapparent. There is another

‘species of this genus still undescribed in the cabinet of Mr.

Schwarz; it is larger and stouter than macer. |

NOTES.—The S. bicolor, referred to by Schaufuss in suppressing the name

bicolor Lec., is evidently the Anthicus bicolor of Fabricius, from South Amer-

ica, and not the S. bicolor of Denny, as I surmised (ante, p. 371). Anthicus

bicolor is said by’ Erichson to be allied to clavipes Say (Schaum, Mon., p. 18),

-but there seems to be too much doubt connected with the subject to warrant a

change of name for the present, and I would therefore advocate the retention

of the name given by LeConte.

The species placed in Euconnus by Dr. Sharp (Biologia Cent. iia ) will,

I think, be forced ultimately into several distinct genera. On looking over

the admirable figures on the plate, it seems natural to place giraffa, mutandus

and guatemalenus, for example, in one genus, and cheriquensis and germanus in

another, the latter distinguished by peculiarities of pronotal sculpture and an

unusually elongate antennal club. Calvus, as before remarked, will probably

‘enter the genus Pycnophus, although the third joint of the maxillary palpus,

‘as figured, is different from that of P. rasus, the type of the genus; it is pos-

sible, however, that this may be an oversight on the part of the artist. Gra-

cilicornis, incultus and some others appear to form each the type of a distinct

‘genus. |

The genus Napochus of Thomson, is in all probability closely allied to Con-

nophron, but differs apparently in the more prominent tempora and trans-

verse eyes, and also in having a distinct plica at the sides of the thoracic base.

ADDENDA.

There are several described species in this family within our

faunal limits, which I have not been able to place satisfactorily in

the tables previously given; these are added as follows for the

sake of completeness —

Scydmeenus consobrinus Lec.—Proc. Acad. Nat. Sci., Phila., 1852, p. 154.

—Piceous-black, the head glabrous; prothorax rather long, pilose, rounded

and narrowed anteriorly, transversely impressed at the base; elytra sparsely

pilose, foveate at the base; antennz clavate, with the penultimate joints

rounded. Length .05 inch. New York.

Precisely similar to clavipes but differing in the antenne, these being some-

what longer than the head and prothorax, with joints three to six equal,

closely connected and not longer than wide; seven a little Jarger and slightly

conical, eight to ten rounded, not longer fa wide; eleven about 1g longer

and subacute.

This species may be placed immediately after Huconnus clavipes

in the table.

546 Coleopterological Notices, VII.

Scydmeenus mississippicus Zimm.—Trans. Am. Ent. Soc., 1869, p. 251.—

Ferruginous-brown, very shining and smooth although tolerably thickly

clothed with hair, the head especially thickly covered behind with erect hairs.

Prothorax not longer than wide, narrowed in front, with a slight transverse

impression behind in which four deep fovee are visible. Elytra with one lon-

gitudinal impression in front near the suture and a fovea near the sharply de-

fined humeral carina. Front thighs much thickened, the front tibiz strongly

compressed toward tip, and, on the inner side, furnished with a brush of

hairs. Length nearly 24 line. |

It is evident that this species should be placed among those

members of the genus Euconnus, which I have designated by the

subgeneric name Scopophus, but I cannot identify it with any of

those described.

Scydmzenus gravidus Lec.—Proc. Acad. Nat. Sci., Phila., 1852, p. 155.

—Piceous, pubescent, the prothorax narrowed anteriorly, transversely im-

pressed at the base; elytra shorter than usual, ovate, foveate at the base; an-

tenne slender, the three last joints rounded and abruptly larger. Length .04

inch. Louisiana.

_- Stout, piceous, pubescent, the head rounded, with the antenne a little

longer than the head and prothorax, the joints three to eight equal, not elon-

gate , nine and ten more than twice as thick, globular, eleven a little longer,

obtuse. Prothorax wider than the head, trapezoidal, narrowed anteriorly, the

sides almost straight; base with a strong transverse impression. Elytra some-

what rufous, ovate, twice as wide as the base of the prothorax and forming

with it a very indistinct angle, moderately convex; base strongly foveate.

Thighs slightly clavate, the tarsi testaceous.

May be placed just before Connophron trinifer in the table of

that genus; it differs in the transverse impression of the pro-

thorax.

Scydmzenus obscurellus Lec.—l. c., p. 153.—Piceous, briefly pubescent,

the prothorax rather long, narrowed slightly anteriorly; elytra very slightly

impressed at the base; antennal joints rounded, the legs rufescent. Length

.045 inch. Georgia (Liberty Co. ).

A small species, easily distinguishable by its piceous color and elongate pro-

thorax. Head convex, smooth, strongly pilose at the posterior angles. An-

tenne a little longer than the head and prothorax, the Joints after the second

globular, the four last about }, thicker than those which precede. Prothorax

pilose, not wider than the head, 44 longer than wide, very slightly narrowed

and forming an almost indistinct angle with it, obliquely narrowed behind the

middle, slightly pubescent; base scarcely foveate; feet rufous, the thighs

clavate.

of clavatus, and the two descriptions are very similar. Those

forms of Connophron having the prothorax almost imperceptibly

wider than the head are extremely rare, and there may be reason

to suppose that obscurellus is extremely closely allied to Con-

nophron clavatum, if, indeed, not identical. The length of the

prothorax is, of course, overstated in the description of LeConte.

Scydmezenus mariz Lec.—l. c., p. 151.—Rufo-piceous, sparsely pubescent,

the vertex bifoveate; prothorax campanulate, obsoletely impressed before the

base, foveate at the sides; elytra oval, sparsely and obsoletely punctulate.

Length .065 inch. Michigan (St. Mary’s River. )

Very similar to subpunctatus, but the prothorax is more rounded on the sides

anteriorly and distinctly narrowed behind, the basal impression hardly visible

and the lateral fovese less deep. Elytra wider and much less distinctly punc-

tured, the base marked as in that species with four punctures, causing the

humeri and suture to appear elevated.

There is reason to believe that this species. does not; differ from

Scydmenus subpunctatus.

Scydmzenus minimus Bndl.—Entomologica Americana, V, p. 193. Iowa.

As before stated, this species is possibly not distinct from

Opresus misellus Lec.; its length is said by the author to be .45 to .5

mm., and, if correct, this would prove it to be quite different from

O. luteus, which I have described from the mountains of Pennsyl-

vania. Atany rate, it may be placed next to misellus in the table

of Opresus previously given. In the figure of Dr. Brendel, the

antenne are very strongly clavate.

and no impressions. Elytra elliptical, the humeri obsolete, each feebly de-

pressed at the middle of the base, the sutural lines feebly indicated at basal

fourth. Anterior coxze contiguous; posterior small, mutually remote; femora

clavate. Last ventral segment very large, as long as the three preceding.

Length 0.8mm. California (Sta. Clara Co. ).

In the figure accompanying this description the fourth palpal

joint is shown to be distinct, aciculate and subulate, and there can

be no reasonable doubt that ovithorax will form the type of a new

genus belonging to the tribe Opresini, but differing greatly from

any other in the widely separated hind coxe, |

There are but few characters given in this socotiaoan which are

not distinctive of the entire genus, and it is therefore impossible

to make any useful comparative statements. The two specimens

from Arizona, associated with lucanus by the author, are probably

not identical, as the species of Eumicrus quite closely resemble

each otherin general appearance and are decidedly local in habitat

in our arid and broken southwestern country. It may be placed

just before motschulskii in the table of Kumicrus previously given.

Eumitocerus Csy.—

As remarked by Rey, this genus is singularly isolated from its

nearest relatives, and constitutes a bond in several directions be-

tween the Tachyporini and Aleocharini, resembling the former in

mode of antennal insertion, and the latter in its less inclined

head, undefined epipleure and other characters. Although so

similar to Habrocerus in antennal structure, the palpi, epipleu-

re, point of antennal insertion and hind coxe differ profoundly,

and the two genera cannot be associated. in the same subtribal

group.

The three species of the United States, which are represented

in the material before me, may be readily separated as follows :—

by two specimens, taken some years ago near New York City by

Mr. H. H. Smith, and may be a recent importation. The third

Species is much the largest and broadest, and is described below.

T. lativentris.—sStout, elongate-elliptical in outline, moderately con-

Besides the absence of long bristling setze toward the abdomi-

nal apex, this species differs from the other two in lacking the

long, erect lateral seta near the base of each elytron, in having the

abdominal segments equal in length, the fourth and fifth being

more elongate in tarsalis and pilicornis, and in the more evenly

rounded sides of the prothorax.

PSELAPHIDA.

FARONINI.

MEGARAFONUS n. gen.

In this genus the third antennal joint is very small, as in the

European Faronus, the metasternum extremely short, the abdomen

large, with the first three dorsals subequal in length, the fourth

larger and the first not modified on the disk. From Rafonus it

differs in its more abbreviated elytra, still larger first dorsal, in

having the antennal tubercles separated by an anterior extension

of the frontal pit, and the third antennal joint much smaller; it

further differs in having the fourth palpal joint more broadly oval

and compressed. Other generic characters are included in the

description of the single known species below.

M. ventralis n. sp.—Rather broadly subcuneiform and depressed, gradu-

ally wider from the front to near the tip of the abdomen, polished, impunctate

and dark rufo-testaceous throughout, the legs and antenne paler; pubescence

moderate in length, rather coarse and abundant, recumbent. Head somewhat

small, exclusive of mandibles rather wider than long, scarcely * as wide as the

prothorax, the eyes moderate in size, slightly convex and somewhat prominent,

at rather more than their own length from the base, the tempora behind them

circularly rounded to the neck, slightly less prominent than the eyes and be-

coming parallel near them ; surface moderately convex, with two strong nude

and isolated foveze at basal fourth, separated by 14 of the entire width; frontal

fovea deep and abrupt, with its floor minutely rugose and flat, prolonged pos-

teriorly and narrowed to a slight terminal enlargement at the centre of the

vertex, and narrowed anteriorly, crossing the frontal margin, the latter wide

between the antenne, the tubercles extremely feeble; clypeus extremely small,

being simply a fine porrect and strongly rounded margin at the foot of the

subvertical front between the antennal cavities; labrum strongly transverse,

broadly arcuate and subcarinate at apex, except at the sides, which are ob-

liquely and briefly produced and bristling with coarse sparse sete, the base

much narrower than the apex; mandibles very strongly thickened and exter-

nally angulate at base, the apical portion subtransverse and finely acuminate,

the internal edge very minutely subserrulate; under surface evenly convex,

ond narrower, oval, longer than wide; third minute, globular ; four to eight

equal, nearly as thick as the second, subglobular, moniliform; ninth and tenth

transverse; nine to eleven wider, forming a distinct club; eleventh but little

longer than wide, much shorter than the two preceding. Prothorax slightly

wider than long, widest and strongly rounded near the middle, the sides

strongly and subequally convergent to apex and base, feebly sinuate toward

base ; apex scarcely 94 as wide as the base; disk moderately convex, with a

large, deep and transverse foveiform impression at basal third which is

narrowly produced anteriorly for some distance, and a smaller pit at each side

near basal fourth, continued posteriorly to the base; there is also a smaller

isolated nude fovea near the basal margin at lateral fourth. Elytra short and

transverse, only very slightly longer than the prothorax and about 14 wider,

the sides divergent and feebly arcuate from the just visibly exposed and ob-

tuse humeri; disk completely devoid of humeral plica or basal impression,

flat, with two longitudinal impressions on each from behind the base to or

behind the middle, the outer near the flank and short, the other near the mid-

dle and becoming deep basally ; sutural stria deep, with an external fovea at

base. Abdomen much more than twice as long as the elytra, and, toward tip

rowed. Legs moderate in length, the femora feebly fusiform; third joint of

the hind tarsi twice as long as the two basal joints combined; claws well de-

veloped; middle coxe separated by a narrow lamina. Length 2.65 mm.;

Oregon (Portland). Hubbard and Schwarz.

The type is a male, the sixth ventral segment being sinuate at

tip, the surface feebly impressed toward the middle, the impres-

sion smooth, polished and limited laterally by small erect and

sublaminiform tubercles near the apex; the seventh is inthe form

of an elongate-oval, strongly convex pygidium with its posterior

extremity minutely foveate. I cannot perceive that the male

modifications in this species are at all asymmetric. This is by

far the largest member of the tribe known thus far from North

America. % :

: EUPLECTINI.

A renewed study of the species aggregated under the name Ra-

mecia, shows that they are not in any way closely related to Eu-

plectus, but are allies of Trichonyx, and, at the same time, the

close general resemblance to Euplectus in bodily form, in conjunc-

tion with the well developed second tarsal claw, goes far to dem-

onstrate the impropriety of proposing two distinct tribal groups

for the genera clustering about Trichonyx and Euplectus; at any

rate, if we admit two tribes, we must also recognize several others.

The species of Ramecia exhibit considerable diversity in general

habitus, crinita being quite depressed, with two strong, short

basal carinz on the first three tergites ; the remainder are more

convex in form, much smoother in sculpture and with less de-

veloped abdominal carinz, though in decora the latter are also

visible on the first three tergites, becoming very minute however

on the third. At present, therefore, I can see no reasonable

ground for generic disintegration of Ramecia,

PYCNOPLECTUS n. gen.

The species forming the first division of Euplectus, as pre-

viously defined by the writer (Col. Not., V, p. 454), are not in re-

ality congeneric with Euplectus as represented by the last two sub-

divisions, and should receive a separate name as suggested above.

The species are stouter, less parallel and much more convex in

the body, with more remotely separated and pubescent cephalic

fovese, connected by a more deeply excavated ambient sulcus,

rather more elongate antenne and much more widely exposed

met-episterna. They agree with Euplectus in the structure and

carination of the abdomen, and in the complete absence of erect

capitate sets on the lower surface of the head.

P. temellus n. sp.—Linear and nearly parallel, though quite convex,

shining, pale rufo-ferruginous throughout, the pubescence rather short, coarse,

-subdecumbent and moderately dense, with the usual bristling setze at the sides

of the abdomen toward tip. Head but slightly wider than long, as wide as

the prothorax, the eyes rather prominent and well developed, at somewhat

less than their own length from the base, the tempora strongly convergent and

rounded behind them ; surface impunctate in the middle but rugosely sub-

punctate along the elevated supra-orbital surface from base to apex ; fovez

Pennsylvania (Westmoreland Co.). Mr. Schmitt.

In the male type the fourth ventral seems to be unmodified, the

- fiftu with a small, deep and circularly rounded anterior emargina-,

tion, but otherwise scarcely modified, the sixth with a broad,

sublunate and feeble impression, slightly tumid anteriorly near,

its extremities ; the seventh is rhomboidal, very convex, minutely

and sparsely punctate and with a fine, strongly elevated and some-

what asymmetric median carina, The female differs but little, ex-

cept that the head is distinctly narrower than the prothorax.

This species, which is one of the smallest of the genus, differs

from hudsonicus in its larger eyes, more convergent tempora,

smooth pronotum with short and non-sulciform discal pit, nar-

rower bodily form, and in many other characters.

P. imperfectus n. sp.—Rather large and somewhat stout, convex, elon-

gate, dark rufo-testaceous throughout, impunctate and polished, the pubescence

than the tempora, which are distinctly convergent and broadly arcuate behind

them ; occiput convex, very obsoletely impressed at the middle ; fovese deep,

separated by nearly 14 the total width or twice the distance from either eye,

The single female, representing this species, was formerly re-

garded by me as the female of congener; it cannot have that

status, however, as the abdominal carine are well developed in

congener and the pubescence much denser; it may be placed near

congener for the present. |

The measurement of congener, previously given, is a little too

great, the male type being about 1.35 < 0.4 inm. in size.

EUPLECTUWS Leach.

The following species may be placed near confluens for the

present, differing in the structure of the pronotum.

E. disjumctus n. sp.—Linear, parallel and depressed, polished and

bright rufo-testaceous throughout, the pubescence subdecumbent, coarse, mod-

erate in length and rather abundant. Head large, much wider than the pro-

thorax and wider than long, the eyes rather well developed and convex, at

their own length from the base, the tempora circularly rounded behind them

to the neck, which is distinctly less than 144 the maximum width ; surface im-

punctate along the middle, sparsely punctured toward the sides, with two

small and nude fovee just behind the middle, separated by the eye-distance

of either, and connected by a groove in the form of a horse-shoe ; antenne not

as long as the head and prothorax, the three outer joints gradually wider, the

last rather longer than the three preceding. Prothorax relatively rather small,

feebly convex, subimpunctate, only 44 wider than long, widest and rather

narrowly rounded at apical third, the sides thence gradually convergent to the

‘base and feebly bisinuate ; apex more than 44 the maximum width, and fully

34 as wide as the base ; discal pit narrow and elongate, tending to coalesce

with the median subbasal pit, which is moderate in size, but rounded and not

joined to the well developed lateral foveze by a visible transverse sulcus.

Elytra as long as wide, not quite as long as the head and prothorax, distinctly

wider than the head, the sides subparallel and broadly arcuate ; discal stria

very short, attenuate, extending to about basal third. Abdomen parallel and

straight at the sides, slightly longer and narrower than the elytra, the first

three dorsals equal, the fourth much longer ; first two each with two short

feeble and divergent basal carinz, separated by less than 44 the total width ;

border well developed, flat and inclined. Legs short and stout ; third joint of

the hind tarsi about as long as the second, the claw well developed. Length

Represented by a single female example, hitherto confounded

with confluens, which it resembles somewhat in form and size ;

in confluens the subbasal median pit of the pronotum is extended

laterally in a feeble arcuate groove to the lateral fovee, and, in the

present form, the head is larger and more sparsely punctate, and

the discal stria of the elytra shorter. The last ventral segment

is broadly and arcuately lobed at apex, the surface ascending

apically and convex.

BIBLOPLECTUS Reit.

In this genus the body is narrow, linear and subdepressed as in

Euplectus, and the mesosternal side-pieces are divided in the

same way into two nearly equal triangular sclerites by fine

sutures; but in Huplectus the met-episterna are slightly wider

anteriorly, while in the present genus they are very narrow,

parallel, linear and entirely covered by the elytra, the anterior

pubescent fovese of the metasternum being much smaller and

more punctiform. It differs from Euplectus in its more narrowed

front, in its 5-jointed antennal club, this beginning really with

the seventh joint, and in the type of male sexual form of the

seventh ventral segment. Asin Euplectus, the middle tibiz of the

male have a distinct internal uncus at apex, but, unlike that genus,

the hind tibiz in the same sex are broadly grooved externally

toward tip; the tarsi are much shorter and thicker in the female

than in the male. The under surface of the head is completely

devoid of erect capitate sete, but there are four remarkable spini-

form appendages arranged in a transverse line anteriorly, one at

each apical angle of the mental support, and one at each outer

posterior angle of the buccal opening. The first four dorsal seg-

ments are exactly equal in length, the fourth not longer as it is in

Euplectus.

The species are all minute, and the one described below is

closely allied to integer.

B. Sobrinus n. sp.—Slender and moderately convex, shining, piceous-

black throughout, the head slightly paler ; legs and antennsze testaceous ; pu-

bescence fine, short, decumbent, and not very abundant. Head very nearly

as wide as the prothorax, but slightly wider than long, the eyes moderate in

size, convex, at about their own length from the base, the tempora behind

them parallel, rounded and as prominent as the eyes ; occiput broadly sinuate,

minutely impressed at the middle ; surface subimpunctate toward base, sub-

scabrous toward the frontal margin ; foveze small, pubescent, situated slightly

behind the middle and separated by 1 the total width ; from each extends

anteriorly a fine, deep and arcuate groove, the two gradually becoming parallel

and uniting by a strongly arcuate moderate impression between the antennal

tubercles, which are small but pronounced ; antenne shorter than the head and

prothorax, slender, the first two joints larger and equal, three to six equal,

minute and feebly transverse, seventh and eighth wider, equal, ninth and tenth

successively still wider and more transverse, the eleventh wider, conoidal, as

long as the four preceding combined. Prothorax about 14 wider than long,

the sides parallel and straight from apical fourth to basal fifth, there strongly

convergent and sinuate to the base, rounded and rapidly convergent at apex ;

disk broadly, feebly convex, finely, unevenly and not very densely punctate,

without trace of discal pit, the lateral foveze large, united with the trans-

versely triangular median subbasal depression by fine grooves ; from near the

centre of the disk a fine carina extends to the basal margin, crossing the me-

dian depression. lytra subquadrate, feebly convex, slightly punctulate, 14

longer and “6 wider than the prothorax, the sides parallel and broadly arcuate ;

three basal fovese of each strongly developed, the outer continued posteriorly

for a very short distance by a feeble and gradually evanescent sulcus. Abdo-

men very nearly as long and wide as the elytra, parallel and nearly straight at

the sides, moderately convex transversely, the first two dorsals each with a

very feeble basal impression in median third of the entire width, but not

carinate. Length 0.8 mm.; width 0.28-0.3 mm.

Rhode Island (Boston Neck).

The male of this species differs from that of integer in its

slightly larger head, with less abbreviated antenne and more

widely separated foveze, in the more transverse prothorax, much

less broadly rounded and convergent at the sides toward apex,

and in the narrower impression of the basal tergites, which, on

the second segment of integer, appears to extend through nearly

half the total width, though so feeble as to be scarcely definable ;

the pubescence is a little shorter and denser in ¢nteger. The de-

scribed type is a male, the female scarcely differing however in

general form. The series before me is quite extended, and there

is scarcely any variation in size; the males seem to be much less

abundant than the females.

The genera allied to Trimium, forming section 12 of the table

previously published by me (Col. Not. V, p. 442), and section A,

B, of the arrangement of Mr. Raffray in the “ Etude,” require

very much more elaboration than has hitherto been accorded

them. Trimioplectus, which is now represented before me by a

good series taken by Mr. Schmitt, must be associated with these

genera, although the eleventh antennal joint is relatively smaller,

and the ninth and tenth joints larger than usual; it is evidently

homologous in this respect with the African Periplectus of Raff-

ray. The antenne are short throughout this peculiar group of

exceedingly minute and obscure forms, widely separated at base

and with the last, joint large, relatively abrupt’ and ‘elongate-

ogival in form; the body is less linear than in the allies of Euplec-

tus, elongate-oval and always distinctly convex. I would suggest

the following arrangement of genera, those not North American

This particular group of trimiiform genera appeers to be much

more abundant and structurally diversified in the American con-

tinents than in the old world, and will prove to be very extensive,

as the species have been but. seldom collected hitherto owing to

their minute size and secluded habits.

REMARKS.

, Actium Csy.—This genus will include californicum, politum,

robistulwme testaceum, candidum, marinicum, pacificum, brevi-

penne, globifer, parabolicum and the two species described below.

It is much better represented on the Pacific coast than in the At-

Coleopterological Notices, VII. 559

lantic regions, but angustum seems to be perfectly congeneric with

the west coast forms. I am somewhat doubtful in regard to

globifer and parabolicum, which are not represented in the ma-

terial before me; they appear to have the discal stria of the elytra

much more abbreviated than usual.

A. angustum n. sp.—Narrow, elongate, convex and moderately ventri-

cose, polished, impunctate and pale rufo-testaceous throughout ; pubescence

moderate.in length and rather sparse, subdecumbent. Head very slightly nar-

rower than the prothorax, a little wider than long, the eyes well developed,

convex, prominent, at about their own length from the base, the tempora much

less prominent, feebly convergent and broadly arcuate behind them ; occiput

feebly impressed at the middle ; fovee deep, slightly pubescent, just behind |

the middle, separated by fully 2% of the total width, the connecting impression

shallow and angular in form, the antennal prominences strongly tumid ; an-

tenne 1 longer than the head, the last joint elongate, gradually ogival and

almost as long as the preceding five joints, the tenth 214 times as wide as long,

slightly oblique and a little more developed toward the outer side. Prothorax

as long as wide, widest and moderately rounded near the middle, the sides

broadly and rather deeply sinuate thence to the base ; surface convex, the lat-

eral fovese not very large but deep and subpubescent, connected by a deep

transverse groove which is posteriorly enlarged at the middle. lytra almost.

as long as wide, very convex, % longer and fully #5 wider than the prothorax,

the sides divergent from the rather widely exposed humeri, becoming strongly

arcuate behind ; basal foveze two in number ; discal stria fine and extending

almost to the middle. Abdomen about as long as the elytra and slightly nar-

rower, the sides parallel and feebly arcuate ; basal segment equal to the fol-

lowing, with two short basal carinz separated by 14 of the discal width. Legs

moderate in length, the femora feebly and equally inflated. Length 1.2 mm.;

width 0.4 mm. :

A number of specimens were sent to me under the name Z'rimio-

plectus parabolicus, but according to the description and figure,

that species, the locality of which was not indicated by the au-

thor, must be quite different. The description is from the male,

in which sex the sixth ventral is broadly and feebly impressed,

and the oblong-oval flat enclosed pygidium of the seventh is much

smaller than in the Pacific coast forms. The female is less ven-

tricose than the male, with a slightly smaller head and very much

smaller eyes. }

A. bifoveatum n. sp.—Elongate, the hind body wider, convex, polished,

subimpunctate, the elytra minutely, subrugosely punctulate, rufo-testaceous

in color, the pubescence'subdecumbent, rather short and moderately abundant.

eyes moderate in size, convex, at more than their own length from the base, the

tempora behind them much less prominent, parallel and scarcely arcuate to

the truncate base, the latter very feebly and minutely impressed at the base of

the occiput ; fovee slightly behind the middle, large, deep and separated by 14

the total width ; antennz partially missing in the type. Prothorax slightly

wider than long, widest and somewhat prominently rounded before the mid-

dle, the sides thence convergent and not at all s nuate to the base ; fovez large

and deep, connected by a very coarse and deep transverse sulcus, which is an-

gularly dilated posteriorly at the middle ; median line finely and feebly im-

pressed. Elytra not quite as long as wide, % longer and nearly * wider than

the prothorax ; humeral plica rather prominent ; sides nearly parallel, broadly

and evenly arcuate throughout ; disk broadly convex, the sutural stria deep-

and straight ; discal stria distinct, extending well behind the middle; basal

foveee two in number, the intra-humeral depression large. Abdomen decidedly

narrower and somewhat longer than the elytra, parallel and very feebly arcuate

at the sides ; segments equal in length toward base, convex, minutely and

sparsely punctulate basally, the basal carinz rather short, straight, parallel

and separated by fully 14 of the discal width ; secondtral ven segment nearly

as long as the next two combined. Length 1.6 mm.; width 0.6 mm.

California (Siskiyou Co.).

This very isolated species can be distinguished at once from

any other, with bifoveate elytral base, by its large size, very small

head, finely impressed median line of the pronotum, finely rugu-

lose elytra with an unusually long discal stria and by many other

characters. It is represented by a single female in rather poor

condition.

Trimiopsis Reit.—The type of this genus is 7. claviceps Reit.,

from Colombia (Deutsch Ent. Zeits., XX VI, 1882, p. 150), an in-

sect of rather large size for the present group, and having a re-

markable cephalic development. Most of the minute species,

subsequently placed here by Reitter, belong to other genera;

specularts, for instance, is assignable to Melba and eggerst, which

I erroneously regarded as typical of Trimiopsis (Col. Not. V, p.

462),must form the type of another genus named “ Zolium ” in the

table. Some of the characters given in the table in defining

Trimiopsis are assumed, as no allusion to them is made in the

original description, such as the presence of a post-humeral fovea,

isolated lateral pronotal foveze and elongate discal stria of the

elytra, for example. There seems to be a tendency in the large ter-

minal joint of the antenne to split at apex along an axial plane

in many of these minute trimioid forms, and the notice which

I formerly drew to this character in specularis (I. c.) is of no

significance from a generic viewpoint.

Coleopterolugical Notices, VII, 561

Actiastes n. gen.— Founded upon a minute species previously

referred by me to Actium, but differing so much in the arrange-

ment of the vephalic fovez, more elongate basal segment of the

dorsum and other-characters, as to demand a separate genus. Its

type is Trimium foveicolle Lec., which I haye taken abundantly

in Rhode Island, and also received through Mr. Schmitt, from

the mountains of Pennsylvania. Cos/alis, of Brendel, undoubtedly

belongs to this genus, and may be identical with /foveicollis; but

if his measurements are correct, it must be materially larger.

Cupila n. gen.—This distinct genus has for its type the 7rv-

mium clavicorne, of Maklin, a male of which, from Astoria,

Oregon, was kindly given me by Mr. Schwarz. The black color

of the body alone might have led to the inference of generic

divergence from Actium, in which the species are all pale,

as this difference in the coloration would tend to indicate marked

differences inhabits and environment. The genus departs from

Actium in its less convex and more linear form of body, com-

plete absence of discalelytral stria, this being replaced by the

elongate basal fovea of Trimium,in its elongate basal segment of

the dorsum, this having two extremely minute and parallel basal

carine separated by scarcely + of the discal width, and other

characters as related in the table. The sparse subdecumbent

pubescence of the abdomen streams outward in a remarkable

manner, and the male ventral characters are very striking and

confined to the third segment; this segment is profoundly ex-

cavated to its base at about lateral third, the excavations ap-

parently confluent beneath the median ligula, which is dilated at

apex and impressed laterally. The hind tarsi are long, with the

second joint fully 4 longer than the third. The under surface

of the head has exceedingly few erect set, their extremities

minutely capitulate as usual.

Simplona n. gen.—The transverse pronotal sulcus in this genus

terminates laterally in slightly dilated, very deep and perfectly

nude foveee near the rounded and indefinite lateral margin, as in

Trimium, and the tenth antennal joint is as strongly triangular in

a transverse sense asin Trimiopsis, and moreso than in Trimium.

From the latter genus it is distinguishable at once by the large

and deep post-humeral fovea and pleural carina, which are there

completely wanting. The single type is described as follows : —

562 Coleopterological Notices, VIL.

S. arizonica n. sp.—Slender and linear, though quite convex, shining,

the elytra subalutaceous, very pale flavo-testaceous in color throughout, the

head and prothorax minutely, sparsely and asperately subpunctate, the elytra

scarcely visibly, sparsely and very minutely punctulate ; pubescence short,

decumbent and moderately dense. Head as wide as the prothorax, rather

wider than long, the eyes well developed, at rather less than their own

length from the base, the tempora less prominent and circularly rounded be-

hind them to the neck; base broadly sinuato-truncate, not obviously im-

pressed at the middle ; foveze rather small but deep, just behind the middle

and separated by % of the entire width, united transversely by a very

broadly subtriangular groove extending anteriorly only half way to the inter-

antennal line, the frontal margin throughout broadly tumid, the antennal tu-

bercles not well defined ; antennz very short, scarcely 14 longer than the head,

the eleventh joint large, conoidal, as long as the five or six preceding joints

combined and twice as wide as the ninth, the base oblique, tenth triangular ;

erect capitate sete of the under surface rather short and few in number.

Prothorax but slightly wider than long, widest and not very prominently

rounded at about the middle, the sides broadly arcuate and conver gent ante-

riorly, convergent and sinuate toward base ; transverse sulcus strongly flexed

posteriorly at the middle or biarcuate ; disk convex and even. Elytra not quite

as long as wide, scarcely % longer and about °4 wider than the prothorax, the

humeri quite well exposed at base ; sides feebly divergent and broadly arcuate

throughout from base to apex ; disk moderately convex ; sutural stria very

coarse and deep ; basal pit slightly elongate. Abdomen longer than the elytra.

and but little narrower, the sides feebly arcuate ; surface broadly convex, the

first visible dorsal with two short basal caring separated by rather less than 14

of the total width and limiting a decided basal depression, distinctly longer

than the second ; two to four diminishing gradually in length. Legs short, the

femora only moderately stout. Length 0.95 mm. ; width 0.28 mm.

humeral fovea pad pleural cariniform lineasin Actium. Thetype

is Trimiopsis eggersv Reit., from the island of St. Thomas. In

this species the pleural cariniform line is paralleled above by a

series of small punctures, each of which bears a short squamiform

hair, and the fovez of the head are discal, remote from the eyes

and wholly isolated ; the head is about equal in width to the pro-

thorax. The sixthantennal joint of the male is slightly dilated,

-Coleopterological Notices, VII. | eee) 33)

and the ventral characters are somewhat as in Cupila clavicornis

Makl, the third segment having a large rectangular lamina at

lateral third, from beneath which projects obliquely and laterally

a singular wart-like elevation, bearing at its summit a cluster of

remarkable squamules; the..sixth segment is much longer than

the fifth, scarcely modified, and the seventh, or ventral pygidium,

is small and transversely fusiform ; ventrals two to five decrease ©

rather rapidly in length. The last joint of the maxilliary palpi is

elongate, gradually swollen within toward base, and is longer than

the entire basal portion. 7 |

arctic, and does not occur at all in the American continents. As

represented by brevicorne, the body is more elongate than in

Melba, and differs altogether in the formation of the basal parts.

of the prothorax, the transverse dorsal sulcus not extending at

all down the flanks, but terminating at some slight distance

within the rounded lateral edges, in small deep and glabrous en-

largements ; the fovez of the head are nude, rather widely sepa-

rated and feebly connected by a large shallow ambient depression ;

tenth antennal joint slightly asymmetric and transversely trian-

gular or cuneiform. Elytra with an elongate discal fovea at base,

without trace of a post-humeral fovea, but with a very fine pleural

line extending parallel to the side margin from before the middle

to the apex, its anterior point of origin entirely indefinite.

First dorsal elongate, with a median depression at base, the

second ventral nearly as long as the next three combined.

Tarsi slender and densely clothed with very short stiff hairs,

the terminal claw quite small, slender and feebly arcuate.

Trimiomelba n. gen.—Greatly resembles Melba in the form of

body, but differs in the elongate first dorsal and second ventral

segment, which character is accompanied by a larger head,

flatter above, with the sides more abruptly vertical, the foves ©

more remote; the head is frequently, or perhaps always, more or»

less modified in the male, which seems never to be the case in

Melba. The penultimate antennal joints are small, lenticular and

symmetric. The hind tarsi are long and slender, the second joint

twice as long as the third, the claw very small and slender. The

species are three in number as follows:— _

fine, short, decumbent and rather inconspicuous though somewhat abundant.

Head rather large, fully as wide as the prothorax, almost as long as wide,

feebly convex, the eyes very small, slightly prominent, at nearly twice their

own length from the base, the tempora less prominent behind them, long,

feebly convergent and but slightly arcuate to the basal angles, which are ob-

tusely rounded ; occiput not visibly impressed ; fovez slightly behind the

middle, large, separated by more than 14 the entire width, the ambient. sulcus

large but shallow, becoming lost anteriorly in the shallow depression between

‘the moderate antennal prominences, the sulcus with some scattered coarse

punctures near the prominences ; antennz 4 longer than the head, the last

District of Columbia.

This species is allied to convexula, which was described from

Tampa, Florida, my representative being from Crescent City. It

differs from convexula, as compared in the female, in its rather

Coleopterological Notices, VII. 565

smaller eyes, longer, less arcuate and less converging tempora,

unimpressed occiput, broader head and prothorax with less

rounded sides of the latter, and in several other features.

As usual in the present genus, the elytra have at the sides a

fine line beginning at the base, extending posteriorly, very grad-

ually receding from the edge, more rapidly toward tip and attain-

ing the elytral apex; this line does not seem to be entirely homo-

logous with the very’strong post-foveal carina of Cupila and

related genera. The sutures defining the side-pieces of the me-

sosternum are obliterated, but there isa fine straight longitudinal

carina extending from the apical margin to the hind hmits of the

middle coxe; at some slight distance externally from them, and

just external to this carina at its posterior limit, there begins a

large and deeply impressed channel, extending obliquely outward

and vanishing at about the middle of the metasternum at a con-

siderable distance from the side margins. In Melba the confor-

mation of these parts is nearly similar, but the oblique channel is

very short and the elytra! flanks have an oblique line extending

from near the middle of the lateral edges to the apex.

Melba n. gen.—This genus wiil include Trimium thoracicum

and puncticolle, and, in all probability, also parvulum, gracile,

laticolle, majus and discolor, which I have not seen. The head is

not quite so large as in Trimiomelba, and is apparently not modi-

fied in the male, the last antennal joint large and conoidal, the two

penultimate joints small, lenticular, gradually wider and virtually

symmetric. The first dorsal segment is not elongate and is not

narrowed at base as it is in Dalmosella, the second ventral not

as long as the next two and bi- or triexcavate sublaterally at base,

the sixth large in the male, the seventh enclosing a large, oblong-

oval, liguliform pygidium. In the male the anterior, and especi-

ally the intermediate, femora are greatly swollen, while in Tri-

miomelba this character is scarcely noticeable. In Melba

sulcatula the intermediate male tibiz are obtusely but strongly

prominent within just beyond the middle, this character not being

observable in the corresponding sex of any other species which I

have seen. In puncticollis the abdominal carine are very short

and separated by about 4 the discal width; in thoracica, which is

nearly similar, the carine are slightly longer and are separated

by only about 4+ ofthat width. TZrimiopsis specularis Reit., from

the island of St. Thomas, may be assigned to this genus for the

present, although the male sexual characters are of a slightly dif-

ferent order, the ventral pygidium being much shorter and semi-

circular, the second and third ventrals tuberculate sublaterally,

and the anterior and intermediate femora not particularly swol-

len; the anterior femur is foveate on the posterior edge just be-

yond the middle, and the corresponding edge of the middle femur

is carinate at the middle. , |

The species of Melba are all very small in size and may be as-

signed to four groups by the following characters :— .

Basal intra-humeral fovea of the elytra short.

Pronotum impunctate.

Occiput impressed or canaliculate at the middle .............c cee se eens Group 1

Occiput not impressed ........ pelbidbie sided egw akg Sibu dla aad Lenesounaten aa eee Sd Group 2

Pronotum finely and asperately punctate .............c6c0 seessesereeneenoes Group 3:

Basal fovea large and elongate ; species rather less minute .............06 Group 4

The first group comprises parvula, texana, sulcatula, laticollis

and discolor, the second gracilis of Brendel, the third puncticollis

-and thoracica, and the fourth maja, fossiger and uniformis. Dis-

color is said to have no occipital impression by Dr. Brendel in

his paper on the genus Trimium (Tr. Am. Ent. Soc., XIX, p. 166),

but is particularly defined by its channeled occiput in the mono-

graph of the Pselaphide by that author (Nat. Hist. Bull. Univ.

Iowa, II, pp. 32 and 34); the latter statement is in agreement

with the description of LeConte.,

The four species which follow appear to be undescribed hith-

erto.

M. texamna n. sp.—Moderately ventricose, strongly convex, polished and

impunctate, pale testacevus throughout, the pubescence fine, short, decumbent

Texas (Columbus ). Hubbard and Schwarz.

The intermediate femora in the male type described above, are

greatly swollen, the upper edge very strongly arcuate, the lower

feebly sinuate, the tibiz simple; the fifth ventral is notably short,

scarcely visible except laterally, the sixth large, slightly flattened

toward the middle and the horizontal pygidium rather large, as

wide as long, circularly rounded behind, nearly flat and quite im-

punctate. In the female the head is slightly smaller but similar

otherwise. ‘T'wo specimens.

Texana is closely related to discolor, but differs in color, that

species being described as chestnut-brown with the abdomen

darker ; discolor is said by LeConte to occur in Louisiana.

M. sulcatula n. sp.—Moderately stout, convex, shining, impunctate

and pale brownish-testaceous throughout, the pubescence very short, fine,

decumbent and abundant. Head slightly narrower than the prothorax, con

vex, not quite as long as wide, the eyes small but rather prominent, at slightly

more than their own length from the base, the tempora behind them less

prominent, slightly convergent and somewhat arcuate to the base ; occiput

the entire width ; supra-antennal prominences pronounced, crossed obliquely

by a narrow groove; antenne 14 longer than the head, slender, the second joint

larger and more oval than the first, eleventh very large, conoidal, more than

twice as thick as the tenth and as long as the five preceding. Prothorax dis-

tinctly wider than long, the sides parallel and almost evenly rounded, strongly

narrowed at base, the sides becoming parallel in basal third or fourth ; disk

strongly convex, the sulcus deep, strongly angulated at the middle, continued

uninterruptedly down the flanks. lytra distinctly shorter than wide, %

longer and 84 wider than the prothorax, the sides moderately divergent from

the slightly prominent humeri:to the apex and broadly, rather strongly arcu-

ate; intra-humeral fovea deep, evanescent before basal third, the sutural stria

fine and feeble. Abdomen rather longer than the elytra and nearly as wide,

the sides parallel and feebly arcuate ; apex broadly parabolic ; dorsals equal,

the first with two short fine parallel carinz at base, separated by about of

the entire width. Length 0.8 mm.; width 0.3 mm.

Besides the tibial character before referred to, the anterior

femora of the male above described are moderately, the interme-

diate very strongly, swollen, the upper contour of the latter

strongly arcuate, the lower very feebly sinuate toward the middle ;

the posterior trochanters are acute at tip, the abdominal charac-

ters extremely feeble and the ventral pygidium large. The female

differs but little, the head being only slightly smaller than in the

male. |

This minute species is allied to parvula, but differs in the elon-

gate occipital impression, which takes the form of a fine sulcus

extending anteriorly to a point midway between the fovee. In

parvula, which was described from a unique taken in the neigh-

borhood of Charleston, 8S. C., the transverse sulcus of the prono-

tum is said to be nearly straight; in sulcatula it is distinctly

though broadly angulate. It is probable that the Z’rimium par-

vulum, described by Dr. Brendel in his revision of the genus Trim-

ium, is the present species or one closely allied.

M. fossiger n. sp.—Moderately stout and ventricose, strongly convex,

polished and impunctate throughout, pale brownish-testaceous, the legs and an-

tenne slightly more flavate ; pubescence rather coarse, short, subdecumbent,

only moderately abundant. Head very slightly narrower than the prothorax,

as long as wide, the eyes moderate in prominence, rather small, at much more

than their own length from the base, the tempora behind them but slightly

less prominent, long, feebly arcuate and but just visibly convergent to the

_ base, the angles well defined though rounded ; base distinctly impressed at the

middle, the impression not prolonged forward to the vertex ; fovez large,

moderately deep, nude, situated just behind the middle and separated by

nearly 14 the total width, united by a very feebly impressed ambient sulcus,

which is not materially enlarged behind the slightly tumid frontal margin ;

antennal prominences small but rather distinct ; antenne 44 longer than the

head, the second joint oval, distinctly larger than the first, ninth but little

wider than the preceding, transversely cuneiform, tenth distinctly wider, very

short and transversely lenticular, virtually symmetric, the eleventh as long

as the five preceding combined and twice as wide as the tenth. Prothorax

and straight, and is gradually shallowed externally but without

indication of any particularly distinct punctures, as alluded to in

the description of maja. |

M. umniformis n. sp.—Strongly convex, moderately ventricose and im-

punctate, resembling the preceding in color and vestiture. Head about equal

in width to the prothorax, fully as long as wide, the eyes rather well developed,

moderately convex and prominent, at scarcely more than their own length

from the base, the tempora behind them slightly less prominent, quite dis-

tinctly convergent and continuously arcuate to the base ; occiput distinctly

impressed at the middle, the impression carried forward, gradually becoming

feeble nearly to the line of the fovee, the latter rather large and deep, nude, at

basal % and separated by nearly 44 the total width, connected by a feeble

ambient sulcus; antennal prominences small but strong ; antenne nearly as

in fossiger, except that the ninth joint is but little larger than the eighth and

almost perfectly symmetric, the tenth not so broad and less than 14 as wide as

the eleventh. Prothorax slightly wider than long, the sides circularly arcuate,

becoming abruptly straight and parallel in rather more than basal fourth, the

sulcus broadly biarcuate and rather deep, not dilated at the median flexure.

Elytra nearly as in fossiger but rather less abbreviated, with the sides not quite

so divergent from the moderately prominent humeri, the basal fovea large,

rather abruptly evanescent and extending through basal % of the length;

sutural stria not obviously punctured externally, except very minutely and

feebly toward tip. Abdomen as long as the elytra and obviously narrower,

convex, the dorsals equal, the first with two flat triangular parallel carinz in

less than basal third, separated by less than % of the discal width. Legs

rather slender, the femora moderately inflated. Length 1.0 mm.; width

0.4 mm.

Rhode Island (Boston Neck).

Also described from the female and closely related to the pre-

ceding, differing in its less elongate and more rounded tempora,

more anteriorly extended occipital sulcus, relatively somewhat

smaller prothorax, shorter, deeper and more abruptly defined basal

fovea of the elytra and some other characters. It is rather re-

markable that of the sixteen examples before me not one is a

male, and, so far as I know, the male in this peculiar group, hav-

ing a more elongate basal fovea of the elytra, remains unknown.

- Dalmosellan. gen.—The general form of the body in this genus

is nearly as in Melba, but narrower and slightly less convex. The

antenne differ quite distinctly in structure, being shorter and

more compact, with the ninth and tenth joints larger, the latter

transversely triangular and the eleventh more evenly and acutely

conical; the cephalic foves are larger and strongly pubescent, the

eyes more developed and the abdomen slightly narrowed or con-

stricted at the base. The mesoparapleure are obliquely divided by

a fine suture, the epimeron much the larger, with its posterior

margin strongly defined by a transverse, anteriorly arcuate suture

extending from the coxe to the elytral margin; adjoining this

line posteriorly, there is a large pubescent fovea. The flanks of

the elytra have a fine line extending from about basal third to the

apex and parallel throughout to the side margin. Dalmosella in-

cludes some of the most minute of the Pselaphide, and, besides

the type described below, I am inclined to assign to it the.

Trimium americanum and T’. simplex of LeConte, the former

being 0.6, the latter 0.5 mm. in length.

D. tenuis n. sp.—Narrow, subparallel, moderately convex, impunctate,

pale brownish-testaceous throughout, the pubescence moderately short, sub-

decumbent, quite coarse and. not very dense. Head a little narrower than the

prothorax and quite distinctly wider than long, the eyes rather large and well

developed, convex, finely faceted and at about 14 of their own length from the

base, the tempora much less prominent, convergent and obtusely rounded be-

hind them ; occiput just visibly impressed at base but not sulcate ; fove

large, deep, pubescent, at about the middle of the length and separated by a

little less than 14 the entire width, united by a very feeble arcuate impression

scarcely extending 14 the distanee to the frontal margin, the latter arcuate at

tip ; antennee very short, scarcely 14 longer than the head, the two basal joints

larger as usual and subequal, the second somewhat angularly prominent within,

three to seven equal in width, short and compactly joined, eighth a little wider,

transversely oval, ninth still wider, lenticular, almost symmetric, tenth wider

and transversely triangular, eleventh conical, only 14 wider than the. tenth,

as long as the five preceding combined. Prothorax slightly wider than long,

widest at about the middle, the sides convergent and rounded anteriorly, the

transverse biarcuate sulcus distinct, deep on the descending flanks constricting

the prothorax between basal third and fourth, the surface bordering the stric-

ture anteriorly not very prominent but more strongly pubescent ; sulcus not

dilated at the middle; disk even. lytra not quite as long as wide, % longer

and 34 wider than the prothorax, the sides broadly arcuate, nearly parallel and

but feebly divergent from the slightly exposed humeri, widest behind the mid-

dle ; disk moderately convex, the sutural groove rather deep, the discal re-

longer than the elytraand only just visibly narrower, widest at the middle, the

sides parallel and somewhat strongly arcuate ; first dorsal a little longer than

the second, with two short parallel basal carine, 1g as long as the segment

and separated by rather more than 14 of the discal width, the intervening sur-

face somewhat more impressed ; ventrals two to four rather long, rapidly de-

creasing in length, the fifth much shorter. Legs slender, the femora but slightly

inflated, the hind tarsi rather elongate, with the second joint nearly twice as

long and thick as the third; claw very small. Length 0.7 mm.; width

0.27 mm.

Pennsylvania (Westmoreland Co.).. Mr. Schmitt.

The only specimen known to me isa female. The under sur-

face of the head has but few very short capitate seta, and the

ventral sutures are straight and transverse throughout.

Basolum n. gen.—This name is proposed for a genus which

appears to be rendered necessary to fit the published characters

of Trimium impunctatum of Brendel, from the middle Atlantic

regions. ‘The head is said to have two oblong isolated fovesx, the

ambient sulcus wholly obsolete, the first antennal joint elongate,

being twice as long as wide, the maxillary palpi small, with the

third joint obliquely rounded and larger than the fourth, which is

obliquely conoidal; the elytra are said to have a fine discal stria

extending to the middle. The described characters of the maxil-

lary palpi are extraordinary and wholly exceptional among the

genera allied to Trimium and Actium; this, and the elongate

basal joint of the antennee, would necessitate its generic isolation

under any circumstances, and I am by no means certain that it

will prove to be allied to Trimium at all. For the present I would

also place in this genus the Zrimium durum of Brendel, (Tr. Am.

Ent. Soc., XIX, p. 166), in the description of which it is stated

that the frontal sulcus is interrupted at the middle, that the discal

stria of the elytra extends to the middle and that the third joint

of the maxillary palpus is globular, half as thick as the fourth,

the latter but little longer than wide. If duruwmis not a Basolum

it will require a distinct genus, on account of palpal structure. I

have been unable to study either of these remarkable species. On

request, Mr. Ulke, of Washington, sent me what he stated to be

the only example of 7. impunctatum in his cabinet. This proves

to be merely a representative of a species of Actium, apparently

identical with angustum, described above, having the basal joint of

the antenne rather smaller than the second, the cephalic fovex

united by a deep parabolic sulcus and the palpi perfectly normal.

572 Coleopterological Notices, VII.

I can scarcely imagine, however, that Dr. Brendel could have made

three such radical mistakes in his description of tmpunctatum,

and therefore leave the matter for further development.

Trimioplectus Bndl.—The body in this genus, as represented

by TZ’. obsoletus, the type and only known species, is convex and

formed nearly as in Melba, the mesoparapleure and metasternal

fovea as in Dalmosella, the flanks of the elytra wholly without

trace of post-humeral fovea, but with a fine line parallel to the

side margin in apical half. The biarcuate pronotal sulcus is almost

exactly as in the European Trimium, being at a greater distance

from the base than in the related American genera owing to the

greater elongation of the prothorax, and ending near the lateral

edges in slight, nude, punctiform dilatations. The head is smaller

than the prothorax, wider than long, with large well developed

eyes and short tempora, and with two small, nude, widely sepa-

rated aud wholly isolated fovez at some distance behind the mid-

dle, the frontal margin rather wide and separated from the vertex

by a feeble transverse sulcus, which is feebly and posteriorly ar-

cuate and disconnected in every way from the fovee ; the palpi are

normally trimiiform. The antenne are much longer than in any

of the allies of Trimium or Actium, and the joints are less trans-

verse and more loosely connected, the tenth joint of the male

about 4 wider than long, the eleventh but little longer than the

preceding three combined. The long bristling setz of the under

surface do not seem to terminate in knob-like enlargements, but

to have their extremities asperate for a short distance. The discal

impression of the elytra extends broadly impressed and substri-

iform to or beyond the middle. The abdomen is formed in quite

a different manner from that characterizing the allies of Melba

and Trimium, the segments decreasing in width from the apex of

the first; the first dorsal is notably longer than the second, with

a feeble transverse impression at base extending through nearly

+ the discal width and limited by abrupt but scarcely cariniform

lateral extremities, the formation nearly as in Trimium. The sec-

ond ventral in the male is nearly as long as the next four combined

along the middle. but much shorter at the sides, the seventh in the

form of a transverse semicircular pygidium, and the third has a

small pubescent tubercle at the apex and lateral fourth or fifth.

The genus is remarkably isolated among the American forms,

Coleopterological Notices, VII. Sats:

but seems to be allied, as before stated, to Periplectus, from the

east coast of southern Africa.

BATRISINI.

BATRISUS ae

The possession of a long terminal | opendaes of the hind tibise

characterizes by far the greater number of forms inhabiting the

Atlantic coast regions, and, if the genus, is to be divided, this will

perhaps prove to be a better criterion than the pronotal oulpi eee

assumed by Reitter; the genus Arthmius, which is constantly as-.

sumed by Reitter and Raffray to be a subgenus of Batrisus, is in:

no way closely related, as I have previously pointed out; the

South American species with strongly modified front in the iiailea?

possibly do not belong to Arthmius at all. In some of the east-

ern species of Batrisus there are sexual differences in the pygidium.

analogous to those known to exist in the California representa-

tives. In schaumt, for example, the pygidium of the male is:

semicircular and merely tumid, while in the female it has a short.

but acutely elevated discal carina; in that species the long slender

spine of the intermediate legs projects from basal third or fourth

of the femur of both sexes, and is not confined to the male or at-

tached to the trochanter as stated by. Brendel.

B. temporalis n: sp.—Rather slender,’ convex, polisted, pale rufo-testa-’

ceous in color throughout, minutely and sparsely punctulate, the punctules of

the head and pronotum feebly asperate; pubescence moderate in length :

strongly reclined, coarseand somewhat sparse.. Head distinctly narrower than

the prothorax and 1ather longer than wide, the eyes moderate in size, convex

and prominent, at a little less than their own length from the base, the tem-

pora nearly parallel, feebly arcuate and less prominent behind them to the

basal angles, which are well defined; upper surface but slightly convex, shining

behind, dullin nearly apical half owing to very coarse polygonally crowded

punctures which extend to the transverse crest of the front between the an-

tennse; there the front becomes declivous in about 45 degrees, and narrowed

betcen the large antennal cavities, with the apex broadly and feebly bilobed :

the surface of the sloping portion is deeply and broadly excavated, polished

and impunctate, and has at the middle a triangular elevation prolonged an-

teriorly into a fine process projecting in the feeble sinus of the apical margin;

the triangular elevation bears two pairs of acute setigerous tubercles both ar-

ranged transversely, the posterior much the larger, the anterior very approxi-

mate and minute; the clypeus beneath has a double edge, with a medial cari-

niform setigerous elevation, the apex of which appears at a slight distance be-

fore the sinus of the bilobed frontal edge and at the same level; posteriorly

considerable distance in a gradually evanescent impression, but are wholly

isolated transversely; an acute spiniform process arises nearly midway between

each and the median line, which is deeply grooved throughout, except near the

base, where the groove becomes a feeble carina; a feeble longitudinal ridge ex-

tends anteriorly from each spiniform process. Elytra nearly 44 longer and 34

gradually and uniformly in a large flat surface to a broadly and subcircularly

arcuate apical margin far before the antenne, attaining and only a slight distance

above the apical margin of the clypeus, the shallow vertical wall separating

the two edges perfectly smooth and slightly concave ; the flat and feebly slop-

The female differs from the male, above described, in having the

pygidium a little larger and more transverse, father less convex,

with the groove along the lower margin narrower but rather.

deeper and with its upper margin more acute and subcariniform;

the last ventral is broadly convex, while in the male it has a.

rather small and elongate-oval median impression, smooth and of

moderate depth. In the female the structure of the front does not:

differ greatly from that of the male but the sculpture is finer and

denser and the antenne are simple, the last three joints gradually

wider; the fovez are less basal and somewhat less widely sepa-.

rated and the basal carinee of the abdomen are still shorter and.

separated by fully 4 of the discal width. In the general form of

the body the sexes do not differ greatly, but the elytra in the:

female are less abbreviated and about as long and wide as the ab-

antennal joint, and it differs further in having a more convex,

more finely and asperately punctate, steeper and setigerous frontal

declivity, smaller fovese, which are united by a continuous feeble

ambient sulcus, a narrower and more trapezoidal pygidium, a

longer and more contorted apical tibial process, and in numerous

other features. Riparius is common in the Ohio valley, from the

headwaters of which, in Westmoreland Co., Pa., I have a small

series taken by Mr. Schmitt; the present species is its homologue

abnormal outline and medial impression of the eleventh antennal

joint; it may be placed near fovezcornis in the lists.

piceous-black throughout, the legs somewhat paler, the antennal club pale ;

pubescence rather abundant, pale in color, long, suberect and bristling. Head

small but convex and prominent, at distinctly more than their own length

from the base, the tempora behind them very rapidly convergent and circularly

arcuate to the neck ; foveze only moderate in size, near basal third, pubescent,

Pennsylvania (Westmoreland Co.).

This is one of the more interesting of the numerous important

discoveries of Mr. P. Jerome Schmitt, and is dedicated to him

with the liveliest appreciation of the continual increase in knowl-

edge of our microcoleoptera due to his skillful and patient re-

searches in the mountains of Pennsylvania, the treasures of which

are only beginning to be unfolded. The single example before

me is a male, with, however, no special secondary marks other

than those described, the last ventral and pygidium even, being

perfectly simple and unmodified. The species may be placed

near sirzatus in our lists.

ARIANOPS Bndl.

The two species of this remarkable inquilinous genus before

me may be readily distinguished as follows :—

Pubescence dense; prothorax shorter than wide, more inflated anteriorly, and

much more than 4% as wide as the elytra, the latter distinctly longer than

the prothorax, with the sutural impression feeble throughout. @Q Penn-

latter not evidently longer than the prothorax, much shorter and more

transverse, with the sides more arcuate and divergent, the suture strongly

depressed “posteriorly. °: 9 ~ Carolimas’...s. 25.6.5 600. -sa0e5 plectrops n. sp.

As far as known the genus is confined to the Appalachia

Mountain system, where it represents the European Amaurops.

A. plectrops.—Moderately slender, strongly convex, highly polished,

impunctate and uniform dark rufo-testaceous throughout, the hind body

elongate-oblong and moderately stout; pubescence long, suberect and somewhat

sparse. Head longer than wide, about equal in width and length to the pro-

thorax, semicircularly rounded behind the erect, compressed triangular spicules

representing the eyes, the spicules each continued forward in a fine carina at

the lower margin of the antennal cavities to the base of the mandibles; upper

surface convex, with two deep nude foveze near basal fourth, separated by

about % of the maximum width, each at the posterior limit of a broad and

moderately deep sulcus, the two uniting anteriorly in a large gradually

declivous smooth and polished frontal depression between the antennal prom-

inences, which are large and somewhat roughly sculptured; front before the

depression more rapidly and subvertically declivous and strongly narrowed by

the antennal cavities to the very short and more porrect clypeus, which is very

broadly subparabolic at apex ; labrum transverse, broadly sinuate at tip and

bearing some stiff discal setze ; mandibles rather small, stout. Antenne about

as long as the head and prothorax, moderately slender, but slightly irregular,

the club 3-jointed; basal joint short and thick, but slightly longer than wide,

the apex above moderately emarginate for the reflexion of the funicle ; second

much narrower, elongate, rather longer and slightly thicker than the third;

two to seven gradually somewhat narrower and less roughly sculptured, all

longer than wide and subeylindric, the eighth narrowest of all, quadrate;

ninth and tenth subequal and nearly similar, moderately transverse, scarcely

as wide as the basal joint; eleventh much thicker, large, conoidal and gradu-

ally very acute to the tip, rather longer than the three preceding joints com-

bined. Prothorax slightly elongate, widest and evenly rounded at the sides

anteriorly, the sides gradually and moderately convergent posteriorly, becom-

ing only very feebly sinuate; surface evenly convex, with three large deep

nude and isolated fovece near the base, the lateral partially confluent with an-

other smaller fovea nearer the basal margin, the median flanked on either side

by a small and feebly prominent spinule and only slightly prolonged anteriorly

for a short distance in a rapidly evanescent impression; at the base in the mid-

dle there is a small elevated and more rugosely sculptured triangle, flanked by

single smaller fovese. lytra very short and transverse, as long as the pro-

thorax and nearly 45 wider, nearly °4 wider than long, the sides very strongly

divergent and strongly evenly arcuate, from the extreme base to the apex, the

surface strongly convex, not foveate at base but each with two feeble impres-

sions adjoining the elevated basal margin, the fine sutural strie lying in a

broadly impressed sutural region which becomes very deep toward tip; flanks

deep, without trace of post-humeral fovea but with a fine cariniform line

parallel to the margin in more than apical half; humeral plica or prominence

wholly wanting. Abdomen more than twice as long as the elytra from a ver-

tical viewpoint, and, at the middle, rather wider, the sides parallel and feebly

arcuate; border only visible on the basal segment, narrow, slightly oblique

and feeble; basal segment with three wide shallow basal impressions separated

by feebly cariniform elevations; second and third short and equal, the fourth

longer than the first three combined, very convex, becoming gradually vertical

at tip; fifth ventral short but longer than the third or fourth, the apical mar-

gin oblique at the sides, disappearing laterally under the third dorsal. Legs

long and well developed, the femora moderately swollen; tibiz long, the pos-

terior calcarate at tip. Prosternum before the coxe elongate.and almost hori-

zontal. Length 2.8-3.0 mm.; width 0.8-0.85 mm.

The description applies to the male, the exserted cedeagus being

large and of remarkable form. In the female the head is more

distinctly wider than the prothorax, the latter about 4 as wide as

the elytra, the abdomen shorter with more arcuate sides, the first

dorsal much longer than the next two combined, the fourth but

little longer than the first; behind the fourth there is a short

dorsal part of the large exsertible sixth ventral, which dorsal part

may be completely hidden at times under the fourth dorsal ; be-

hind this again there is a short transverse pygidium. In the male

the dorsal pygidium is large, transversely oval, with two deep

perforate cavities on the median line, the lower the larger, and is

strongly exsertible, the sixth ventral very mobile but fixed at base,

fitting in a large circular emargination of the fifth, with its apex

broadly sinuate, the sinus cusped at the middle. The spiracle of

the large fourth dorsal is at the middle of the lateral edge and is

at the summit of a small oblique tubercle. The female of ambly-

oponica in my cabinet, which I owe to the kindness of Mr. Schmitt,

is 2.85 X 0.88 mm. in size, so the measures of Dr. Brendel are prob-

ably somewhat too great, though the female is rather smaller than

the male, as in many Batrisi.

BrRYAXINI.

DECARTHRON Bndl.

The following species is sufficiently common, even in Massa-

chusetts, but seems to have been unaccountably overlooked :—

D. laurenticum n. sp.—Black and polished throughout, the elytra

generally not paler, ventricose ; pubescence long, abundant, erect, bristling

and rather dark in color. Head nearly as wide as the prothorax, the eyes large

and prominent, the tempora short ; foveze distinct, separated by scarcely more

than 4g the entire width ; antennal prominences large. Antennx black, stout,

bristling with long erect setee, scarcely longer than the head and prothorax ;

joints three to six subglobular and equal; seventh and eighth a little wider

than the preceding, transverse and equal ; ninth nearly twice as wide as long.

Prothorax rather small, slightly wider than long, less than 1 as wide as the

elytra, widest a little behind the middle ; apex more than 144 the maximum

width ; median fovea small but deep and punctiform, the lateral wholly obso-

lete. lytra short, fully 144 wider than long, the sides strongly divergent

from the base, broadly arcuate throughout; discal stria extending to apical

third. Abdomen as wide as the elytra and distinctly shorter, the first segment

broadly arcuate at tip, a little more than twice as wide as long ; carine arcu-

ate, feebly. divergent,extending beyond. the middle of the segment.. Legs

moderate, dark brownish-rufous in color throughout.. Length 1.25 mm. ;

Coleoptervlogical Notices, VII. 585

A small species, comparable only with abnorme, but differing in,

its smaller size, shorter and black elytra, black antenne and

darker pubescence. Theintermediate femora of the male are mod-.

ified nearly as in that species, but the second antennal joint is:

subglobular, wider than the first and wider than long, and not.

narrower, cylindric, and fully as long as wide as it is in abnorme.

The description is taken from the, male.

There are three examples before me from Los ie aS Co., Cal-

ifornia, which I cannot clearly separate from brendeli Csy. Tes is

possible that the females from Albuquerque, New Mexico, de-

scribed by Brendel under the name discolor, may belong to the

same species.

BRYAXIS: Leach.

The following species belongs to the group containing foveata,

terebrata, intricata, and others having the second dorsal segment

indented in the male :—

B. arguta n. sp.—Rather strongly ventricose and convex, shining, subim-

punctate, the elytra very sparsely and obsolétely punctulate ; body and an-

tenne dark piceous, the elytra slightly, and legs and antenne distinctly, paler ;

pubescence moderately short, subdecumbent and not at all dense. Head but

slightly narrower than the prothorax, the eyes large, strongly convex and

prominent, the tempora very short and convergent behind them ; three fovee.

equal and normal. Antenne obviously longer than the head and prothorax,

moderately slender, the club gradually but rather rapidly formed ; first three

joints decreasing slightly in width, the first but little longer than wide ; sec-

ond cylindric, feebly elongate; three to eight equal in thickness ; third and

fifth not quite 44 longer than wide; fourth, seventh and eighth as wide as.

long ; sixth a little longer than wide.; ninth and tenth obtrapezoidal, increas- |

ing, similar in form, slightly transverse. Prothorax minutely, feebly and.

sparsely punctulate, nearly 14 wider than long, widest and rather prominently

rounded at the middle, the three spongiose foveee subequal and well developed.

Elytra almost 2 wider than long, twice as wide as the prothorax, the sides dis-

tinctly divergent from the base and broadly, evenly arcuate ; strie strong and

normai. Abdomen, from above, slightly narrower than the elytra and much —

shorter, the carinz straight, divergent, about 14 as long as the segment and

separated by % of the entire width. Legs normal, rather slender. Length.

deep; from the bottom of the sinus projects posteriorly in the

same plane a flat, gradually narrowing cluster of agglutinate seri-

ceous sete, extending slightly beyond the general apex of the

segment, its apex emarginate; second segment having a shallow

simple rounded indentaticn with ill-defined margins, occupying

rather less than median third and extending almost to the poste-

rior edge; the anterior margin of the indentation lies far under

the apex of the first, and, by longitudinal vision, seems to be re-

flexed as is usual in the species of this section. Remainder of the

abdomen simple, the last. ventral very short. The female is a

little smaller and darker in color, with the elytra still shorter,

more divergent and straighter at the sides and less convex, the

abdominal carine shorter and apparently less divergent.

REICHENBACHIA Leach.

The species aggregated below under this name form a perfectly

natural and isolated division of the Bryaxini, which must conse-

quently have generic value. It is probable, moreover, that this

generic weight will prove constant throughout the geographic

range, and that the so-called connective bonds which have been

noted will form types of intermediate genera. Decarthron, Nisaxis

and Anchylarthron, of our own fauna, are instances of these.

The genus is very extensive within the boundaries of the United

States, and will prove troublesome on this account to the student.

In the following table all the known species are included, with

the exception of three, which will be alluded to below, and the

characters throughout are those of the male, except when the

other sex is specially designated. In the cases of inepta, neva-

densis, complectens and subtilis, the female is the only sex known,

but, in the first of these, the distinguishing features are non-

sexual, and in the last two. there are characters of taxonomic

value in the female antennz, which will be expressed in con-

junction with corresponding characters of the same sex in their

allies; the position of nevadensis will be more or less uncertain

until the male is discovered, although it undoubtedly belongs to

the division with aberrant male antenne.

adequately described, the few words attached to the names by the

author being barely sufficient to establish their status as published

species. In regard to the former, it is more than possible that the

elongate median elevation in the broad concavity of the last two

ventrals, alluded to by the anthor, may simply be adherent for-

eion matter; if not, it is a character altogether unique in the

Coleopterological Notices, VII. 593

genus; the body is said to be 1.5 mm. in length, ferruginous, with

long abdominal lines proceeding from a small rounded fovea, and

the species is from Illinois. TZrzgona is larger, 1.8 mm. in

length, ferruginous, with approximate and diverging abdominal

lines proceeding from a triangular tubercle, the last ventral of the

male having a deep and sharply defined but not large oval fovea ;

it is from Missouri. Both of these species may be placed, for

convenience, near divergens, but it is impossible to state anything

definite about them in the absence of the types. Bicolor seems

to bea remarkably aberrant species in its short and stout antenne,

with the eighth joint three times as wide as long and the next

two transverse, in its small and non-prominent eyes, very con-

spicuous median fovea of the pronotum, and in the peculiar color-

ation and habits; its position among the other members of the

genus is altogether uncertain, and it may be placed at the end of

the series as generically doubtful.

The identity of canadensis with gemmifer is a surmise, and

may prove to be incorrect. Dr. Brendel was in error, however,

in attributing short abdominal carinze to gemmifer, and the spe-

cies identified by him under that name is probably that which is

named subsimilis in the table; gemmifer has long abdominal

lines, a transverse, deeply punctate prothorax, strongly rounded

at the sides, and seems to agree in all characters of the descrip-

tion with canadensis. My previous reference of canadensis to

divergens was an inadvertence, as the prothorax in the latter is

virtually impunctate and smooth, and my allusion to the prothorax

as sparsely punctate (Col. Not. V, p. 482) was an error due to

confusing that species with substmil¢s. Litoralis Bndl., which I

previously regarded as identical with znopia, is apparently differ-

ent, the abdominal carine as described being much longer. The

small, uniformly pale, ferruginous species, of which this is one,

are somewhat abundant ; the four already known are demissa, dis-

tans, litoralis and tnopia. 3

Of congener I have one example which is labeled “ Illinois,”

but this is possibly an error. The characters of semtrugosa are

taken from the male type kindly communicated by Mr. Schmitt.

Peregrinator is the species referred to by me formerly (Il. ¢.) as

eribricollis; I have since obtained the true eribricollis, which

is quite a different thing and more western in habitat. Minuta

Bndl., is synonymous with Nisaxis tomentosa, as I learned some

594 Coleopterological Notices, VILL.

time since by letter from the author. No allusion to the form of

the hind tibiz in polita Bndl.,is made in the original descrip-

tion, and I can only guess at its affinities as stated in the table;

it quite possibly does not differ from propinqua.

The last four species of the table have been previously defined

at greater length (I. ¢., p. 486), but the figures on the plate there

presented are not exactly correct, there being no such difference

in the relative proportion of the third and fourth joints of the

antennee of complectens and tumida, and the median joints in the

female of tumida, as figured, are too much swollen. These two

Species are very much alike in the female, but probably diverge

more in the male. |

The abdominal carinz constitute a useful character, but fre-

quently differ notably in length and distance asunder in the two

sexes, and all references to them in the table are consequently

confined to the male except when the contrary is stated. There

also seems to be some individual variability in these carine inde-

pendent of sex, the extent of which I have had no available op-

portunity to determine as yet.

The divisions of the genus by the primary characters laid down

in the table are apparently not only taxonomically natural, but

geographic as well. For example, the first division is confined to

the continent east of the Rocky Mountains, and does not extend

at all further to the westward as far as known. ‘The second divi-

sion consists of two sections, one with simple tibiz in both sexes, »

which is confined entirely to the Pacific coast regions of Califor-

nia and thence somewhat to the northward, and another, with

spatuliform hind tibize in the male, which extends entirely across

the northern portion of the continent from the Atlantic to the

Pacific. The third division is confined to the arid regions of the

southwest, or the so-called Sonoran province, and is apparently

the only type of the genus occurring there.

The species announced as new in the table are described below

in the same succession, and in every case from the male type only.

R. subsimiilis.— Moderately ventricose, the hind body distinctly elon-

gate and suboblong, dark rufo-testaceous throughout, the elytra not paler, the

abdomen somewhat darker; pubescence ashy, moderately short and abun-

dant and rather coarse. Head distinctly narrower than the prothorax, im-

punctate, the fovee strong, deep and forming an equilateral triangle; eyes

convex and well developed, at less than their own length from the base. An-

tenne a little longer than the head and prothorax, the second joint but slightly

equal in width, feebly obconic, the eighth parallel; third fully 14, fourth and

sixth 4, fifth nearly 14, longer than wide; seventh quadrate; eighth 44 wider

than long; ninth a little wider, 14 wider than long; tenth similar but larger;

nine to eleven increasing rapidly, the latter nearly as long as the preceding

four. Prothorax % wider than long, widest before the middle, the sides not

acutely rounded, rather strongly convergent and feebly arcuate toward base,

finely, sparsely punctate; median fovea distinct and perforate. lytra nearly

1g wider than long, the sides strongly divergent and broadly arcuate from base

to apex; humeral plica feeble; sutural stria deep, the discal more feeble; inter-

mediate basal fovea deep, strong and circular; disk sparsely punctulate and

feebly undulato-rugulose, highly polished. Abdomen minutely and sparsely

punctulate, as wide as the elytra, the first segment more than ly as long as the

latter, the carine 7% as long as the segment, distinctly divergent, arcuate and

very approximate. Length 1.2 mm.; width 0.65 mm.

Iowa (Iowa City).

The male has the first and last ventrals subequal in length, and

each broadly and just visibly impressed in the middle, the latter

broadly and arcuately lobed at apex to fit the broad and rather

deep sinuation, with broadly rounded es angles, at the apex

of the last cee

In the male the abdominal carine are separated at base by the

full strial interspace, but in the female they are separated by only

about 4 of this distance, and are withal distinctly shorter and

nearly straight through equally divergent. In the female of di-

vergens they are separated at base by the full strial interspace.

This species is allied rather closely to dzvergens, but may ‘be

known from it, not only by the female abdominal carine, but by

the larger eyes, more punctate pronotum and less sculptured

elytra and also by the somewhat smaller size. Divergens is com-

mon about Massachusetts Bay.

R. kanSana.—Moderately ventricose, strongly convex, highly polished

and impunctate throughout, rather pale rufo-testaceous, the head scarcely, the

abdomen perceptibly, darker ; pubescence long, erect and bristling, moderately

abundant. Head notably narrower than the prothorax, the eyes prominent,

moderately large, situated at rather less than their own length from the base.

_ Allied to rubicunda, but differing in the form of the abdominal

caring, in the relatively smaller head, more slender and elongate

antenne, less inflated hind body and in the rather feebler sinus of

the last dorsal segment. The male has the first ventral wholly

unmodified, the last moderately large, feebly bitumorose in the

middle near the base and very feebly impressed toward tip, which

is broadly and briefly lobed ; last dorsal rounded, finely, sparsely

punctate, with an impunctate median line, the apex with a rather

broad and moderately deep sinus having very broadly rounded

lateral limits. In rubicunda the last ventral is much more nar-

rowly and arcuately lobed at apex, and is merely flattened toward

the middle of the disk.

R. ursina.—Strongly ventricose, polished, convex and impunctate

throughout, rufo-testaceous, the abdomen infuscate ; pubescence long, brist-

ling, erect and abundant, pale in color as usual. Head nearly as wide as the

prothorax, with distinct and normal fovez, the eyes prominent and situated at

rather less than their own length from the base. Antenne rather slender, with

a gradually formed and moderate club, 144 as long as the body; second joint

cylindric, slightly longer than wide ; three to eight equal in width and nar-

rower ; three to five elongate and almost equal, about 144 longer than wide ;

fifth just visibly longer than the fourth, the latter distinctly longer than the

sixth, which is % longer than wide; seventh a little shorter but fully 14

longer than wide ; eighth a little wider than long, the ninth similar in form

but larger ; eighth to eleventh very gradually and somewhat rapidly wider ;

eleventh obliquely acuminate, longer than the three preceding combined. Pro-

thorax as in kansana but relatively smaller and somewhat less transverse, not

more than 44 as wide as the elytra. Elytra short and transverse, the sides

strongly divergent and almost evenly arcuate, the humeral swelling large but

not very prominent ; sutural stria deep, the discal rather feebly impressed ;

basal foveze distinct, the sutural stria becoming sulciform toward base. <Abdo-

Western Missouri.

Coleopterological Notices, VII. 597

The last ventral of the male is not distinctly tumid in the

middle near the base and has a rather large oval and decidedly

deep concavity, rather well defined, slightly wider than long and

extending from near the base to the apical margin, which is

broadly lobed; last dorsal parabolic, finely and remotely punctu-

late, with a small and moderately deep rounded apical sinus

limited by broadly rounded angles.

This species differs from both rubicunda and kansana in the

much deeper concavity of the last ventral, and, from gracilis,

which also possesses a deeply concave last ventral, it differs in its

nearly parallel and not widely divergent abdominal carine,

smaller and less transverse prothorax and smaller sinus of the

last dorsal, this segment also being much less punctate.

The four species rubicunda, kansana, gracilis and ursina form

anatural group, distinguished by the long bristling pubescence.

‘The species are closely allied among themselves in general ap-

pearance, but appear to be definable by the characters given in

the table. The material before me is not sufficiently extensive

to disclose possible variations in the extent and direction of the

abdominal carinee, which exist to a visible degree without doubt.

RR. insolita.—Moderately ventricose, the hind body oblong-elongate,

strongly convex, highly polished, subimpunctate, piceous-black, the elytra

rufous, the abdomen black ; legs and antennz pale; pubescence very short, stiff,

recurved, only moderately dense, the elytra with a few remotely placed, short

and erect tactile hairs visible under high power only. Head quite distinctly

narrower than the prothorax, normally foveate, scarcely punctulate, the eyes

prominent and well developed, at much less than their own length from the

base. Antenne slender, distinctly longer than the head and prothorax, the

club gradually formed and not very stout ; second joint much narrower than the

first and not quite 14 longer than wide; three to eight still much narrower,

equal in width ; third *, fourth and sixth barely 44, fifth 1, and seventh

26, longer than wide; eighth as long as wide; ninth obtrapezoidal, rather

longer than wide; tenth nearly as long as wide, the eleventh obliquely pointed

and as long as the three preceding combined. Prothorax scarcely 1g wider than

long, widest at about the middle, the sides moderately strongly rounded, con-

vergent and sinuate to the base, the apex barely %¢ as wide as the base; disk

strongly convex, finely, sparsely punctulate, the median fovea small but deep

and perforate. Elytra but slightly shorter than wide, twice as wide as the

prothorax, and %4 longer, the sides moderately divergent and broadly arcuate;

humeral swelling pronounced; striz fine but strong. Abdomen as wide as

the elytra, shorter when viewed vertically, the first segment 14 as long and

nearly three times as wide as long, the carine fine, straight, about %¢ as long

Rhode Island (Boston Neck).

The male has the first ventral feebly flattened in the middle

toward apex and the last large, broadly concave in about apical

half or more, and broadly truncate at tip, the tergum gradually

quite strongly though sparsely punctulate toward tip, with the

last segment very broadly sinuato-truncate; the cdeagus has a

long aud remarkably slender, feebly arcuate and finely pointed

process at each side. The completely fused meso-parapleure are

separated from the metasternum by a broadly impressed, evenly

arcuate suture, attaining the elytra at about apical third. The fe-

male seems to be a little smaller, with shorter elytra and antenne,

but with no difference in the eyes and but little in the abdominal

carine. |

This fine species, among the largest of the genus, was taken in

considerable numbers; it is not comparable with any other de-

scribed thus far.

R. sodalis.—Rather strongly convex and ventricose, polished and subime

punctate throughout, the elytra minutely and very feebly rugulose and the

pronotum just visibly punctulate toward the sides anteriorly, rather pale rufo-

testaceous throughout, the elytra somewhat clearer and the abdomen obscure;

pubescence pale, short, moderately dense, stiff, even and recurved. Head

slightly, though distinctly, narrower than the prothorax, the fovee normal;

eyes large and prominent, at about 14 their own length from the base. Antenne

slender, 44 as long as the body, the club very gradual in formation and rather

slender; second joint distinctly shorter and narrower than the first, cylindric,

nearly 44 longer than wide; three to eight equal in width and still much nar-

rower; third fully #4, fourth and sixth %, fifth more than 1, seventh 14, longer

than wide; eighth as long as wide; ninth and tenth obtrapezoidal, increasing

in size, slightly wider than long; eleventh still thicker, obliquely pointed, as

long as the three preceding. Prothorax only moderately transverse, a little

more than }4 wider than long, not very strongly rounded at the sides, the lat-

ter converzent and sinuate near the base; apex fully 3 as wide as the base;

disk strongly convex, the median fovea rather small but deep and _ perforate.

Elytra slightly shorter than wide, twice as wide as the prothorax and 4

longer; sides distinctly divergent and broadly arcuate; humeral swelling pro-

nounced; striz and basal fover normal. Abdomen not quite as wide as apical

third of the elytra, the basal segment 14 as long as the suture, the carinz fine,

short, strongly divergent and separated at base by but little more than the

strial interspace. Legs normal, the hind tibiz feebly arcuate. Length 1.4

mm. ; width 0.63 mm.

Arkansas (Little Rock).

Coleopterological Notices, VII. 599

The male has the last ventral large, flattened, becoming gradu-

ally broadly and feebly concave toward tip, which is broadly,

arcuately lobed and slightly deflexed; the last dorsal is sparsely

and feebly punctulate and broadly sinuate, with rounded limiting

angles at apex. The female is not represented in the material

before me. This species is also isolated and unlike any previously

known.

R. fusciventris.—Convex. only moderately ventricose, the hind body

oblong-subelongate, polished throughout, rufo-testaceous, the head and pro-

thorax rather more obscure; abdomen black; surface subimpunctate through-

out, the pronotum not obviously punctulate at any part; pubescence short and

decumbent, moderately dense. Head small, scarcely more than 34 as wide as

the prothorax, the foveze normal; eyes prominent and very convex, moderate

in size. Antenne slender, 44 as long as the body, the club gradual as usual

and but moderately stout; second joint a little narrower than the first, slightly

longer than wide; three to eight equal in thickness and much narrower; third

34, fourth, sixth and seventh 44 to 3, fifth fully 1, longer than wide; eighth

not quite aslong as wide; ninth and tenth obtrapezoidal, increasing, a little

the preceding three combined. Prothoraz relatively quite largeand transverse,

nearly 144 wider than long and much more than 14 as wide as the elytra, rather

strongly rounded at the sides, widest just before the middle; disk convex;

median fovea rather small but deep and perforate. Elytra not very transverse

though obviously shorter than wide, the sides distinctly divergent, broadly

arcuate behind; humeral swelling distinct; stris and basal fovez normal.

Abdomen as wide as the elytra, much shorter from a vertical viewpoint, the

first segment more than 14 as long, the carine fine, strongly divergent, about

24 as long as the segment and separated at base by slightly more than the

strial interspace. Legs moderate in length and rather stout. Length 1.4 mm.;

width 0.55 mm.

New York.

This species is somewhat allied to peregrinator, but may be

recognized at once by the less ventricose hind body and sub-

impunctate pronotum. The male has the last ventral rather

large, flattened toward the median line, the flattened surface

ascending toward tip and lobed to fit the broad subcircular sinus

in the tip of the last dorsal, the latter segment feebly punctured.

R. peregrinator.—Strongly ventricose and convex, polished and subim-

punctate, except the pronotum, which is distinctly though not densely punctu-

late, less so broadly along the median line; body dark brown, blackish beneath,

eighth subquadrate but rather longer than wide; ninth feebly obtrapezoidal

and nearly 14 longer than wide; tenth as long as wide; eleventh oval, obli-

quely acuminate and barely as long as the three preceding. Prothorax but

feebly transverse, scarcely more than 14 wider than long, widest just before

the middle, where the sides are but moderately prominent and rounded; apex

barely 36 as wide as the base and not quite 44 the maximum width; disk

slightly convex, the foveze normal, the median rather small but deep and per-

forate. Elytra well developed, a little shorter than wide, the suture a little

longer than the humeral width; sides moderately divergent, broadly arcuate

posteriorly; humeral swelling distinct; strie and foves normal. Abdomen,

from above, nearly as wide as the elytra and 2% as long, the first segment more

than three times as wide as long and scarcely 14 as long as the elytra, the

carine straight, strongly divergent, extending to about the middle of the seg-

in the middle toward base, the surface ascending toward tip in a

flattened depressed plane, the last dorsal distinctly punctulate,

with the tip broadly and deeply sinuate between the more nar-

rowly rounded limiting angles.

R. corporalis.—Strongly ventricose and convex, the hind body some-

what elongate ; body black, the elytra rufous ; legs and antenne pale testa-

ceous ; integuments polished, subimpunctate, the pronotum quite distinctly

though sparsely punctulate, except toward the sides and base and more

narrowly along the median line ; pubescence fine, short, decumbent and mod-

erately dense. Head distinctly narrower than the prothorax, the foveze deep,

strongly developed and normal ; eyes moderately large, strongly convex and

prominent, situated at somewhat less than their own length from the base.

Michigan; Canada (Ottawa).

A large and conspicuous species, readily distinguishable from

puncticollis, which it resembles in form and coloration, by its

larger size, very much feebler sculpture of the pronotum and by

the male sexual modifications. The last ventral of male is large,

and is broadly and distinctly concave toward the middle through-

out, the concavity smooth; the last dorsal is well developed,

sparsely and distinctly punctulate, the apex very broadly and

strongly sinuate in circular arc with somewhat narrowly rounded

lateral limits, the sides thence moderately oblique and almost

straight to the base. In puncticollis the last ventral of the male

is much smaller, and has a narrower and feeble, oval concavity

along the middle, the last dorsal more narrowly and very feebly

sinuato-truncate at tip.

R. borealis.—Similar in form to the preceding but much smaller, pol-

ished, black or piceous-black with pale rufous elytra, legs and antennz, sub-

impunctate, the pronotum sparsely and feebly punctulate, becoming smooth

toward base; pubescence short, strongly recurved and moderately dense. Head

distinctly narrower than the prothorax, the three fovee normal; eyes moder-

ately large, convex, sitaated at rather less than their own length from the base,

Antenne but little longer than the head and prothorax, the club very gradu-

ally formed as usual; second joint cylindric, much smaller than the first, at

least 7g longer than wide; three to eight equal in width, the former obconic,

the remainder cylindric; third *¢, fourth and sixth slightly more than 1s, fifth

24 and seventh barely more than 4, longer than wide; eighth nearly 4g wider

than long; ninth obtrapezoidal, about as long as wide, the tenth slightly wider

than long; eleventh very gradually and obliquely pointed, rather longer than

the three preceding. Prothorax nearly 7s wider than long, widest scarcely be-

fore the middle, the sides moderately prominent and rounded; apex barely 14

of the maximum width and nearly % as wide as the base; surface strongly

convex, the foveze normal, the median deep and perforate. Elytra well devel-

oped though barely twice as wide as the prothorax, only slightly shorter than

vergent, becoming broadly arcuate; humeral swelling conspicuous; strize and

fovee normal. Abdomen, from above, as wide as the elytra and %% as long, the

basal segment nearly 44 as long, not quite three times as wide as long, with

the apex broadly arcuate; carine not quite attaining the middle, rather

strongly divergent and separated by 14 the total width, by rather less.at base.

Legs rather slender. Length 1.25 mm.; width 0.6 mm.

Canada (Ottawa,—Mr. W. H. Harrington); Massachusetts

(Lowell,—Mr. Blanchard).

Apparently an abundant and rather widely distributed species,

closely allied to puncticollis, but distinguishable by the feeble

sculpture of the pronotum, diverging and not parallel abdominal

carine, shorter antennee and slightly smaller size; the fifth joint

of the antenne in puncticollis is more than twice as long as wide,

and the obtrapezoidal ninth and tenth are both longer than wide,

The sexual characters are nearly as in punctticollis, the last ventral

being feebly concave along the middle and the last dorsal feebly

sinuato-truncate at tip, the truncature about 2 as wide as the

base. The specimens from Lowell may possibly represent a

variety, as the antennal joints are not proportioned exactly the

same and the elytra are relatively a little shorter, but all the

other characters are apparently similar; in these examples the

eighth joint of the male antenna is about as long as wide and

quite obliquely truncate at tip, the ninth and tenth both distinctly

wider than long. The elytra in the female of this species are

rather shorter, with more diverging sides and are frequently more

_ obscure in coloration.

R. distans.—Moderately ventricose, convex and pale flavo-feruginous

throughout, the elytra still somewhat paler; integuments shining, quite dis-

tinctly though sparsely punctulate throughout, the pronotum smooth along

the median line and toward base, the head slightly punctulate toward

base ; pubescence very short, moderately dense and strongly recurved.

Head only slightly, though obviously, narrower than the prothorax, with

normal fovez, the eyes moderately large, convex, situated at distinctly

less than their own length from the base. Antennx slightly longer than

the head and prcthorax, moderately slender, the three outer joints rather

rapidly wider, the last scarcely 14 longer than wide and obliquely pointed ;

second smaller than the first, ovo-cylindric, distinctly longer than wide; three

to eight narrower and equal in thickness, the former more obconic; third 4é,

fourth and seventh 7%, fifth 14 and sixth nearly 44, longer than wide ; eighth

quadrate ; ninth fully as long as wide; tenth distinctly wider than long.

Prothorax with the rounded sides moderately prominent, about % wider than

mum width and % as wide as the base ; disk strongly convex, the fovee nor-

mal. lytra well developed, though scarcely twice as wide as the prothorax,

only slightly shorter than wide, the suture nearly 15 longer than the humeral

width ; sides moderately divergent, broadly arcuate posteriorly ; humeral

swelling quite moderate ; strize and basal foveze normal. Abdomen, from above,

as wide as the elytra and % as long, the first segment distinctly less than 14 as

long, nearly three times as wideas long, the carinz %¢ as long as the segment,

straight, strongly divergent and enclosing 14 the entire width. Legs moder-

ately long, rather slender. Length 1.2 mm.; width 0.6 mm.

Canada (Ottawa). Mr. W. H. Harrington.

A small species, allied somewhat to demissa, but distinguished

not only by the sexual characters as indicated in the table, but by

the larger eyes, less transverse and less prominently rounded

sides of the prothorax and very much more elongate elytra, with

less diverging sides.

R. procera.—Convex, elongate and only feebly ventricose, highly pol-

ished, dark red-brown and subimpunctate throughout, the pronotum not dis-

tinctly punctulate at any part, the sutural regions of the elytra feebly and

subserially punctured ; pubescence rather short, coarse, moderately abundant

and strongly recurved. Head much narrower than the prothorax, with normal

fovez, the eyes quite moderate in size, prominent and situated at about their

own length from the base. Antennx but slightly longer than the head and pro-

thorax, the club very gradual in formation as usual; second joint almost as large

as the first, ovo-cylindric, % longer than wide; three to eight equal in width

and much narrower, the third more obconic as usual; third and fifth %,

fourth, sixth and seventh subequal and about 14, longer than wide; eighth

about 44 wider than long ; ninth and tenth obtrapezoidal, nearly similar in

form but increasing, both obviously wider than long ; eleventh rather longer

than the three preceding, obliquely pointed in apical half. Prothorax about 14

wider than long, obviously more than 14 as wide as the elytra, widest and

rounded at the sides before the middle but not very prominently ; apex fully

1g of the maximum width and % as wide as the base ; surface very convex,

the lateral foveze situated at basal third. lytra short, nearly 44 wider than

long, 44 longer than the prothorax, the suture but slightly longer than the hu-

meral width ; sides strongly divergent and broadly arcuate ; humeral swelling

rather feeble ; strise and fovez normal, the former deep, the sutural receding

more from the suture and more arcuate in apical half, the discal slightly everted

toward tip. Abdomen, from above, about as wide as the elytra and fully as

long, the basal segment 36 as long, 244 times as wide as long, the carinee very

fine, straight, just visibly divergent, less than 15 as long as the segment and

enclosing barely 14 of the entire width. Legs moderate in length, the femora

rather stout. Length 1.35 mm.; width 0.55 mm.

604 Coleopterological Notices, VII.

This is quite an isolated species, which I am unable to compare

with any other, and which will be readily identifiable among

those of the present group by its elongate form. The male has

the last ventral concave at the middle, the last dorsal with an even

and moderately broad sinus, limited by broadly rounded angles,

the entire margin having a distinct beaded edge. The locality is

open to some doubt, but will probably be found to be correct as

surmised above.

R. arcifer.—Rather strongly ventricose, convex, and highly polished

throughout; rufo-testaceous, the head less pale and the abdomen blackish,

impunctate throughout, the pubescence moderately short and dense, coarse and

strongly recurved. Head distinctly narrower than the prothorax, with the

usual equilateral triangle of deep pubescent fovesr, the eyes very prominent

and situated at obviously less than their own length from the base. Antenne

long and slender, 35 as long as the body, the club gradually formed; second

joint relatively small, much shorter and narrower than the first, #4 longer than

wide; three to seven equal in width and obviously narrower, much elongated ;

third 1, fourth just visibly more than 1, fifth nearly 144, sixth slightly more

than 1, and seventh 14, longer than wide; eighth slightly thicker and more as-

perate, properly forming a part of the club, quadrate ; ninth obtrapezoidal,

slightly elongate; tenth not quite as long as wide, slightly asymmetric, the

inner angle at apex more acute; eleventh not as long as the three preceding,

obliquely pointed, the inner side flattened toward base. Prothorax nearly %

wider than long, widest before the middle, the sides rounded but not partic-

ularly prominent; apex a little less than 144 the maximum width and not % as

wide as the base; surface strongly convex, the lateral fovese at basal 24; me-

dian fovea normal, perforate. Elytra well developed, twice as wide as the pro-

thorax, slightly shorter than wide, the suture 44 longer than the humeral

width; sides distinctly divergent and broadly and distinctly arcuate; humeral

swelling distinct; strie and fovez normal. Abdomen shorter and quite dis-

tinctly narrower than the elytra, the first segment rather long and well devel-

oped, with the carine straight, short and parallel, scarcely 4 as long as the

segment and separated by a little more than 4 of the total width. Legs rather

long, the intermediate femora notably swollen toward the middle. Length

1.5 mm.; width 0.68 mm.

Kansas.

The intermediate tibiee of the male are compressed and broadly

arcuate, except toward apex, the outer edge bristling with long

erect hairs; the last ventral is large and is evenly concave, with

the apex sinuate and bilobed, the last dorsal short and broadly

sinuate at tip, apparently in circular arc, with rather clearly de-

fined subangular lateral limits. It is unnecessary to add that

this is one of the most distinct forms of the genus in its aberrant

sexual characters.

R. taphrocera.—Rather strongly ventricose, convex, shining, black,

the elytra rufous; legs red-brown, the antenne dark red-brown; head toward

base, pronotum except along the middle and toward base, elytra and abdomen

toward tip, finely, feebly and sparsely punctulate; pubescence fine, short,

moderately dense and closely recurved. Head only very slightly narrower

than the prothorax, somewhat wider than long, the vertexal foves widely

separated, deep and equidistant from base and apex; eyes moderately promin-

ent, situated at about 14 their length from the base. <Antennx slightly longer

than the head and prothorax, the club gradually formed but large and stout;

portion beyond the second joint arcuate in repose; second joint large, excavated

beneath; third obtriangular, wider than long; fourth still wider, twice as wide

as long; fifth moderately dilated, suboval, slightly transverse; sixth equally

wide but shorter, parallel, 4 wider than long; seventh and eighth equal in

width and very slightly narrower, the former slightly wider than long and

longer than the sixth, the latter shorter, more pointed within, 74 wider than

than long, widest but not very prominently rounded before the middle; sur-

_face very convex, serially punctured along the basal margin for a short dis-

tance, the median fovea rather small but deep. Elytra well developed, slightly

shorter than wide, the suture 14 longer than the humeral width; sides rather

feebly divergent, broadly and distinctly arcuate throughout; humeral swelling

very moderate; striz and fovez normal. Abdomen nearly as wide as the elytra

and % as long, the carine of the first segment fine, strongly divergent, straight,

extending not quite to basal third and separated at base by 4 the entire

width. Legs rather slender, the hind tibiz broadly arcuate throughout,

gradually clavate with circular cross-section toward tip. Length 1.2 mm.;

width 0.6 mm.

California (Monterey Co.).

This species was briefly referred to by me (Bull. Cal. Acad.

Sci., II, p. 195) as deformata Lec., and the antenna was figured

on the accompanying plate under the same name; it is a smaller

species than deformata, the latter differing besides in having the

~ second antennal joint larger and unexcavated beneath, the sixth

joint oblique and subtriangular, sixth and seventh slightly nar-

rower, equal in size and transverse and the eighth still smaller

but equally transverse, the elytra, also, broader at base with more

developed humeri. The male of this species has the last ventral

moderately large, flattened but not impressed, and with a rounded

R. falli.—Strongly convex and ventricose, shining,

black, the elytra bright rufous; legs piceous, the tibia

slightly, the tarsi much, paler; antennee blackish; integu-

ments subimpunctate, the pronotum slightly sculptured

along the basal margin; pubescence silvery, rather abun-

California (Sta. Monica, Los Angeles Co.). Mr. H. C. Fall.

In this species the sexual modification of the antennal funicle

is carried to an extreme, and there are sexual modifications of

the basal joint also, and of the hind femora, which render it one

of the most isolated even of the widely differentiated California

Reichenbachiz. The second ventral segment is longer than the

entire remainder of the abdomen, and the last is only moderately

long, flattened slightly toward the middle and feebly, arcuately

smaller, transverse, pointed internally, the next two obtrapezoidal; under

surface of the fifth joint convex and scarcely modified, the sixth with a narrow

vertical ligula projecting from the basal margin, the seventh not excavated

but with the surface gradually and acutely elevated toward the middle of the

basal margin. /Prothorax 75 wider than long, widest near apical third, the

sides there rather strongly but not prominently rounded, thence moderately

Allied in the structure of the front and in other features to the

preceding species, but differing profoundly in the sexual modifica-

tions of the median joints of the antennal funicle and of the hind

NISAXIS Csy.

The species of this genus are smaller as a rule than in Reichen-

bachia, and can readily be distinguished by the complete oblitera-

tion of the vertexal foves, and the median of the three basal fovez

of the elytra; the abdominal carine are as widely separated as in

Decarthron, but are shorter and more feebly developed. The

four components in my cabinet belong to two distinct groups and

may be separated as follows :—

Male with the third dorsal segment broadly flattened, the median parts toward

apex feebly tumid and bearing long erect sete.

Elytra of the male less abbreviated, the abdominal carinz scarcely 14 as

long as the segment ; pubescence abundant and conspicuous.

Elytra decidedly shorter than wide and more arcuate at the sides; abdominal

carinee generally a little longer ; body smaller, with the pubescence less

The first dorsal of the male is deflexed in the middle of the

apical margin, the deflexed lobe transversely excavated and bear-

ing at apex a small nude slender and erect tubercle, the surface of

the tip above the excavation with two small feeble setose tumors.

The second segment is transversely and deeply excavated, the

hind margin reflexed, lamellate and setose in the middle. The

third has two small distant median tubercles, each of which bears

a stiff erect seta. Remainder of the dorsum unmodified. The

last ventral is very short as usual and has a short acute reflexed

apical lobe. The modifications of the tergum are quite similar to

those of maritima, differing principally in degree.

Tomentosa and cincinnata are very closely allied but appear

to me to be at least subspecifically distinct; they have nearly

identical male sexual characters, but so also do maritima and

parviceps, and yet these last are mutually widely separated in

very numerous characters, such as the larger size, more elongate

form, smaller head and very much shorter and more transverse

elytra of the latter.

ANCHYLARTHRON Bndl.

The form described below from the male is closely allied to

cornutum in the sexual modifications of the head and antenne,

but differs profoundly in general habitus, the hind body eine

much shorter and more dilated and the sienna very much more

abbreviated ; the pubescence, also, is decidedly longer.

A. curtipenne n. sp.—Strongly ventricose and ‘convex, polished and

subimpunctate throughout ; body, legs and antenne dark rufo-testaceous, the:

elytra scarcely paler ; pubescence conspicuous, rather long, pale in color, mod-

erately abundant and recurved. Head distinctly narrower but only slightly

longer than the prothorax, subquadrate, the eyes at the middle of the sides,

rather small, moderately prominent and very coarsely faceted ; basal parts of the

vertex elevated obliquely forward in two rounded prominences, separated by less

than 14 the total width, the upper surface anterior to this large and nearly flat to

the frontal declivity, with two small tufts of erect settee at the middle, the

surface very feebly swollen along the median line at the middle and very

broadly and feebly impressed near each antennal prominence, the latter feeble.

Antenne nearly asin cornutum, but relatively more elongate, much longer

than the prothorax and elytra combined, the sixth joint longer than either

of those adjacent. Prothorax scarcely 14 wider than long, widest and rather

prominently rounded before the middle; apex more than 44 the maximum

width and fully ®4 as wide as the base; surface strongly convex, smooth,

sculptured along the base, the lateral foveze small, the median subobso-

lete, all nude. lytra short; nearly 84 wider than long, fully twice as

wide as the prothorax ; sides strongly divergent and distinctly arcuate from

base to apex, the humeral swelling moderate; disk without strize or foves, ex-

cept the sutural line, which is straight, deep and entire. Abdomen about as

wide as the elytra and a little longer, the basal segment broadly rounded at

apex and not quite three times as wide as long ; carine short, subparallel and

very remotely separated. JLegsslender. Length 1.6 mm.; width 0.75 mm. |

Towa.

In the male of cornutum the body is narrower, much less ven-

tricose, flavo-testaceous in color, with the antenne but slightly

longer than the prothorax and elytra, and the latter scarcely more

than 4+ wider than long; the subbasal lobes of the head are flatter

and more broadly rounded, and the pubescence shorter and stiffer.

The following species is evidently congeneric with curtipenne

and cornutum, though much smaller, and is possibly the form

alluded to by Dr. Brendel (Bull. Univ. Iowa, II, p. 4).

A. cCaviceps n. sp.—Ventricose, convex, highly polished and impunc-

tate throughout; body, legs and antenne rather pale rufo-testaceous, the elytra

darker, piceo-rufous; pubescence moderately long and coarse, rather sparse and

strongly recurved. Head a little narrower than the prothorax and distinctly

_ longer, fully. as long as wide, the eyes somewhat small, convex, and situated

atrather more than their own length from the base. Antenne distinctly longer

than the head and prothorax, moderately stout, the club very gradual in for-

- mation, the last joint relatively larger and longer than in Reichenbachia, and

as long as the preceding four combined; second joint distinctly smaller than

the first, cylindric and slightly elongate; third narrower, as long as the second,

strongly obconic; fourth as long and broad as the first, elongate-oval, impressed

internally near the middle and base, without trace of dividing suture; five to

seven smaller, subequal and subquadrate; eighth and ninth wider, obtrape-

zoidal, increasing in size, nearly similar in form and about twice as wide as

long. Prothorax nearly 44 wider than long, widest and somewhat prominently

rounded at about the middle; apex more than 44 the maximum width and

fully 8 as wide as the base; disk strongly convex, smooth but strongly sculp-

tured along the basal margin; lateral foveze small, the median still smaller, all

nude. Llytra fully 144 wider than long, twice as wide as the prothorax, the

Coleopterological Notices, VII. 613

sides strongly divergent and broadly arcuate from the base, the humeral

swelling moderate; disk feebly, longitudinally impressed toward base within

the humeri, but without basal foveze or discal stria, the sutural stria deep and

entire. Abdomen as wide as the elytra and only slightly shorter, the basal seg-

ment broadly arcuate at apex, 24 times as wide as long, with the carine

scarcely more than 4 as long, feebly arcuate, parallel and separated by fully

‘6 the total width. Legs slender, the femora only feebly dilated; hind tibia

broadly arcuate, feebly swollen and pubescent within toward tip. Length 1.35

mm.; width 0.65 mm.

Florida (Lake Worth).

The head in the males of this genus, as well as Pselaptus, is as

singularly modified as in Batrisus. In the present species the oc-

cipital region is feebly convex, smooth and gradually ascending to

a transverse, broadly bilobed truncature at the middle of the

length, this being the posterior limit of a very deep excavation

extending entirely across the head between the eyes, and, posteri-

orly, far under the occipital surface, the bottom swollen in the

middle, the tumor bearing two suberect pointed and setose tubercles

extending upward to about the level of the posterior margin of

the excavation, the two. broadly rounded lobes of the latter with

inflexed yellow sete disposed along the edge. The antennal

tubercles are rather large and are lamellarly prominent within, the

tip of the prominence setose, the two separated by a longitudinal

depression carrying the bottom of the transverse excavation for-

ward to the rapidly sloping front. The clypeal margin is rounded

and minutely reflexed. The ventral apex is not greatly modified,

the sixth segment being broadly truncate in a straight line having

subangulate and slightly prominent lateral limits, this apical line

being also very slightly reflexed in plane.

The generic name Anchylarthron does not seem to be preoccu-

pied, and cannot therefore be changed; it is moreover more ap-

propriate than “* Verticinotus.”

NoTE.—In the male of Pselaptus belfragei Lec., the vertex is broadly con-

cave in the middle from the line through the middle of the eyes to the frontal

margin, the concavity being about 14 as wide as the head, with rounded and

indefinitely limited margins and having at the central point of the bottom a

small and transverse, very feebly elevated and somewhat setose swelling. The

antennal cavities at the sides of the front are prolonged inward dorsally behind

the prominences in a very remarkable manner, separated dorsally by about a

seventh of the entire width of the head and surrounded by a minutely but

strongly elevated bead-like margin, the concave channel separating them lon-

gitudinally being a continuation of the bottom of the large concavity of the

614 Coleopterological Notices, VII.

vertex. The front between the large inferior parts of the antennal cavities is

narrowed and tumid along the middle, descending and expanding to the

clypeal margin, which is broadly arcuate. The basal joint of the antennz is

as long as the next two combined, and the eyes are large, very prominent and

very coarsely faceted. The under surface of the head has three narrow but

very strongly elevated longitudinal carinz, one median and one immediately

beneath each eye. The legs are very slender, the femora thicker than the

tibie but not dilated. This very minute bryaxid occurs from aaa Texas

to Yuma, in California, but is not common.

BYTHININI.

BYTHINUWS Leach.

The name Macherodes, proposed by Brendel for the few Ameri-

can representatives of this essentially European genus, cannot

hold good in the opinion of the writer, and the change of the name

bythinoides to tychoides, made by the author referred to in his re-

cent monograph, is not generally considered allowable by zoologi-

cal authors, such names as Bythinus bythinoides being considered

acceptable under the adopted rules of nomenclature, and there-

fore demanded by the rules of priority. The three species of

Bythinus in my cabinet inhabit the eastern parts of the United

States exclusively, and may be distinguished as follows :-—

Basal parts of the head strongly carinate along the median line.

carinatus Bndl.

Basal parts not carinate; body much smaller.

Pubescence coarse, rather long and sparse (tychoides Bndl. )

bythinoides Bndl.

Pubescence shorter, finer and about twice as dense......... carolinz n. sp.

In the first species the head of the male is tumid and carinate

along the median line for some distance further toward tip than in

the female, and, between the anterior limit of the elevation and

the acutely angulate frontal margin, there is a perfectly smooth

and highly polished depression, containing a trapezium of four

elevated setigerous punctures. I have not noticed analogous

sexual differences in the second section of the table.

B. carolinze.—Convex and rather strongly ventricose, polished, dark

rufo-testaceous in color, the head somewhat, and the abdomen quite notice-.

ably, darker; legs, antennze and palpi still paler; pubescence quite abundant.

and conspicuous, pale in color and strongly recurved. Head fully as wide as

long, much narrower than the prothorax, the eyes moderately small and sub-:

basal; surface throughout with large sparse and concave annular elevations with

minute granuliform pubiferous punctules scattered sparsely over the inter-

Coleopterological Notices, Vil. 615

spaces; general form as in bythinoides, the antennz and palpi also nearly as in

that species. Prothorax scarcely more than 1g wider than long, widest near

anterior third, the sides moderately convergent and nearly straight thence to

the base; surface convex, with large sparse circular and almost completely

effaced areole and minute, scattered granuliform punctules, the transverse

posteriorly arcuate subbasal furrow distinct. Elytra very nearly as long as wide,

the sides feebly divergent, evenly and strongly arcuate from base to apex, the

humeri distinctly swollen; sutural stria strong; surface with minute and sub-

asperate punctures. Abdomen distinctly narrower and much shorter than the

elytra, the dorsal segments short, subequal in length but diminishing rapidly

in width. Legsslender. Length 1.1 mm.; width 0.53 mm.

North Carolina (Asheville).

The second palpal joint is studded with large tubercles, and the

last joint is densely and very regularly clothed with fine, perfectly

erect hairs throughout. The single specimen before me is a male,

the last ventral segment being moderate in length, not impressed

but parabolically rounded at tip.

Pselaptrichus of Brendel, is extremely closely allied to Bythinus.

and should perhaps more properly be regarded as a subgenus,

the elongation of the basal segment of the abdomen being but

slight.

TYWCHUS Leach.

Of the two species described below, the first is allied to minor

and the second rather remotely to puberulus.

T. pocahontas n. sp.—Rather slender, strongly convex, pale rufo-tes-

taceous throughout, the elytra slightly clearer red and the legs and apical part

of the antennz more flavate; pubescence rather abundant, long, coarse, pale

and recurved; integuments highly polished and impunctate throughout. Head

slightly narrower than the prothorax and rather longer than wide, the double

apical tubercle about % the maximum width; eyes well developed, convex,

subbasal and very prominent; surface strongly, evenly convex in little more

than basal half, then declivous to the transverse depression which is situated

at about apical third; longitudinal sulcus of the frontal tubercle rather fine

and deep; small nude punctiform fovese remotely separated at the middle of

the length, each immediately behind a large feeble tubercle having a minute

acute apex; antennz 1 as long as the body, nearly asin minor, the ninth and

tenth joints less transverse and only slightly wider than long. Prothorax very

nearly as long as wide, widest and subangularly rounded before the middle,

the sides nearly straight and feebly convergent posteriorly; apex narrow, % of

the maximum width and scarcely more than 44 as wide as the base; surface

convex and even, with a series of small punctures along the basal margin.

Elytra slightly shorter than wide, fully twice as wide as the prothorax, convex,

the sides moderately divergent, more arcuate behind; humeral swelling narrow

616 Coleopterological Notices, VII.

but strong; discal stria distinct in basal half, the sutural strong. Abdomen

slightly shorter and narrower than the elytra, the first segment deeply im-

pressed along the basal margin from side to side, the sulcus interrupted by two

cariniform bridges, separated by a little more than 44 of the total width. Legs

rather long and slender. Length 1.4 mm.; width 0.55 mm.

Virginia (Norfolk). :

This species is narrower than minor, with slightly longer:

denser and more conspicuous pubescence and with the head nar-

rower, more elongate and less rapidly narrowed to the frontal

tubercle. In minor the transverse depression behind the tubercle

is near apical fourth, and, between the minute nude fovee and

each antennal tubercle, there is an extremely minute spicule, situ-

ated slightly nearer the tubercle than the fovea and arising from

the general. surface without trace of a tuberculiform swelling.

The description and comparisons are drawn from the female.

T. hexagonus n. sp.—Moderately ventricose, strongly convex, polished

and impunctate, dark piceous when mature but frequently paler ; elytra, legs

and antenne always pale rufo-testaceous ; pubescence long, bristling and sub-

erect, rather abundant and conspicuous. Head small, very much narrower

and rather shorter than the prothorax, somewhat longer than wide, the base

rounded in circular arc behind the eyes, which are moderately developed and

prominent ; surface convex, the subfrontal transverse impression situated just

behind apical fourth ; frontal tubercles distinctly less than 1g the maximum

width, separated by a fine sulcus which angularly expands anteriorly ; puncti-

form fovese remotely separated, situated slightly behind the middle and exceed-

ingly minute, the spicules apparently subobsolete; antenne not quite 14 as long

as the body, the basal joint long and cylindric, twice as long as the second and

almost as long as the next three combined, the second cylindric and obviously

elongate; three outer joints gradually larger; tenth nearly 44 wider than long.

Prothorax hexagonal, about as long as wide, widest and angularly rounded at

the middle, the sides thence straight to apex and base, strongly convergent

toward the former ; apex narrow, % of the maximum width and 44 as wide.

as the base; surface smooth and convex, with a coarse elongate furrow at each

side and a small fovea at the middle, all basal; basal margin also with a

single series of small punctures. Elytra slightly shorter than wide, fully twice

as wide as the prothorax ; suture much longer than the humeral width ; sides

rather strongly divergent and broadly arcuate; humeral prominences pro-

nounced ; surface convex, the discal stria coarse and deep, extending slightly

behind the middle, the sutural deep and broadly arcuate. Abdomen slightly

narrower and distinctly shorter than the elytra ; first segment slightly longer,

as usual, transversely rectilinear at apex, impressed along the basal margin,

the impression clothed with very short, subsquamiform, recurved sete. Legs

moderate in length, the femora somewhat inflated, the two anterior pairs

shorter and much less stout than the posterior. Length 1.4 mm.; width

0.6 mm.

Coleopterological Notices, VII. 617

California (Ojai). Mr. H. C. Fall.

Although to be placed near puberulus for the present, this

species bears but little resemblance, differing completely in the

form of the prothorax. The anterior trochanters of the male type

before me are acutely spiculate posteriorly near the base, but there

are no pronounced sexual characters at the ventral apex, the last

segment being truncate at tip and having a very small median

sinus limited by rather pronounced and somewhat prominent ob-

tuse angles.

CTENISTINI.

PILOPIUWS n. gen.

Ctenistes Lec. nec Reich. ; Sognorus Csy. nec Reitter.

The American species formerly placed in Ctenistes by LeConte,

and later in Sognorus by the writer (Col. Not. V,p. 501), must in

reality form a new genus distinct from either. Sognorus was

founded by Reitter upon three species of very small size, Cienistes

oberthtirt and calcaratus of Europe and Syria and s¢monis of

West Africa, the latter of which I now have before me. It differs

from Ctenistes, not only in the minute size of the body and cer-

tain small divergencies in antennal and abdominal structure, but

also in the rudimentary and not well developed appendage of the

second palpal joint. Pilopius differs from Sognorus in having the

second palpal joint extremely bent and clavate, with a well-de-

veloped lateral appendage and the third transversely sublunate,

the second and third ventrals not much longer than the fourth and

the first four visible dorsals equal in length, also in the much

larger size of the body and in having the male antenne very dif.

ferent in structure, the funicular joints being longer and the club

8-jointed. From the genus COtenisodes, recently published by

Raffray (Ann. Soc. Fr., LXV, p. 274), it differs in having no

distinct trace of an angulation or spiniform appendage at the apex

of the fourth palpal joint.

In Sognorus the second palpal joint is much less bent and more

gradually enlarged distally, the third forming a very acute scalene

triangle, and the second and third ventrals, or first and second

apparent dorsals, are much longer than the remainder; the an-

tenn of the male have the joints three to seven very small and

moniliform, and the last four very much developed as in Ctenistes

and Ctenisis. Sognorus seems to be merely a subgenus of Ctenis-

618 Coleopterological Notices, VII.

tes, but Pilopius differs too radically in abdominal structure to be

given a subordinate status,

The genus Pilopius is widely distributed over the continent of

North America, occurring in every part, except the true Pacific

coast faunal province, and is rich in species, but as there are but

few and slight structural divergencies, the latter are difficult to

define. The sexual characters are strongly marked in the antennz

and eyes and in the relative size of the elytra and abdomen, but

are nearly uniform throughout, and the ventral characters of the

male are feeble and practically undiversified. The stiff erect setz

bristling along the lower edge of the anterior femora and tro-

chanters, are equally developed in both sexes in much the same

manner as the distortion of the anterior tibize of Tmesiphorus ;

these setze exist also in the latter genus, but in Cedius are replaced

by three long slender spines.

There seems to be but little doubt that the species of Ctinistini,

though much larger in size as a rule, are lower in the scale of or-

ganization than the first tribes of the Raffrayan arrangement,

such as the Euplectini, this being quite as obvious as in the case

of the large and cumbrous Asidine of the Tenebrionidz, when

compared with the more highly organized, or perhaps geologically

more recent and corporeally smaller, Thinobatini and other re-

lated tribes.

In the following table of species which seem to warrant defini-

tion, all the characters relate to the male alone, except in the case

of impressipennis, of which the only known example is a female.

Small species, always distinctly under 2 mm. in length.

Vestiture rather sparse ; last antennal joint as long as the three preceding

combined or nearly so.

nearly as long as wide ; prothorax rather large and transverse.; species

P. lacustris.—Stout and rather convex, dark rufo-testaceous, the elytra,

legs and antenne paler; abdomen blackish; integuments polished, scarcely punc-

tulate, the pubescence moderate in length, rather sparse, appressed as usual

and subsquamiform, especially at the elytral apices and in the dense masses

dorsal segment. Head a little wider than long, quite distinctly narrower than

the prothorax; eyes large, very coarsely faceted and separated by a little less

than three times their own width; fovese forming a small equilateral triangle;

constriction at the base of the frontal tubercle more than 1% as wide as the lat-

ter. Antenne nearly as long as the head, prothorax and elytra, moderately

stout, feebly incrassate toward tip, the fifth joint elongate, a little longer than

the fourth but shorter than the sixth; tenth much shorter than the ninth, the

eighth quadrate. Prothorax nearly 14 wider than long, about 14 as wide as the

elytra; sides parallel to apical third or fourth, then abruptly convergeat and

sinuate; apex broad, truncate, almost %4 as wide as the base; median fovea very

deep and large, extending beyond the middle. lytra large and well devel-

oped, almost as long as wide, the sides strongly divergent and nearly straight,

becoming arcuate near the tip; humeri broadly rounded and slightly promi-

nent; two basal foveze of each pubescent as usual, the discal groove deep and

strong, entire, the sutural distinct, close to the suture. Abdomen about as wide

as the elytra and much shorter, the segments equal and the lateral border wide,

feebly inclined and discontinuous in external outline as usual. Legs long

and slender, the tarsi very short but slender. Length 1.7-1.8 mm; width

0.72-0.8 mm. |

Michigan; Indiana; Northern Illinois; lowa (Iowa City).

This is the common species of the upper Mississippi Valley and

vicinity of the Great Lakes. It is usualiy confounded with pzceus,

but may be distinguished by its more elongate and pale rufous

elytra. In the female the elytra are a trifle shorter, and much less

than twice as wide as the prothorax, the eyes smaller, separated by

fully four times their own width, and the antenne shorter and

more strongly and rapidly incrassate toward tip as usual; they

are about 4 as long as the body. |

P. saginatus.—Stout and moderately convex, shining and pale rufo-tes-

taceous throughout the body, legs and antenne, except the abdomen which is

blackish-piceous, subimpunctate, the pubescence nearly as in lacustris. Head

distinctly wider than long and but just visibly narrower than the prothorax,

the eyes large and very prominent, separated by three times their own width;

foveze small, deep and not very conspicuous, especially the apical, forming a

small equilateral triangle; post-tubercular constriction °4 as wide as the tuber-

cle; frontal longitudinal groove distinct and long. Antenne long and stout, as

long as the body excepting the abdomen, becoming gradually very stout to-

ward tip; fifth joint moderately elongate, as long as the fourth, slightly shorter

than the sixth and very much shorter than the third; tenth distinctly shorter

than the ninth, scarcely as longas wide. Prothorax 14 wider than long, rather

wider and subprominently rounded at apical third than at base, a little more

than 14 as wide as the elytra; apex broad and transverse; median fovea long,

extending to the middle but only moderately deep. Elytra slightly shorter

than wide, the sides moderately divergent and nearly straight from the obtusely

prominent humeral swelling, arcuate at apex; stris strong and deep, the

Canada (Ottawa—Mr. W. H. Harrington); Rhode Island

(Boston Neck).

Allied rather closely to the preceding but distinguished from it

by the stouter and more incrassate antenne, slightly shorter and

more convex elytra, especially in the female, with the humeral

swelling very much more pronounced and the sides consequently

much less divergent. As in lacustris the female differs in its

shorter and more incrassate antenne, smaller eyes, larger and more

transverse prothorax, nearly 2 as wide as the elytra, in its much

shorter elytra with more diverging sides, somewhat less promi-

nent humeri, and, as apparently usual in the genus, shorter discal

stria and relatively larger abdomen, this being fully as long as the

elytra from a perpendicular viewpoint. The last antennal joint

of the female is fully as long as the four preceding combined.

As usual, the ventral segments.of the male diminish but slightly

in length from base to apex, in marked contrast to the Bryaxini,

and the last is but little longer than the penultimate, with a small

rounded sinus at tip enclosing a minute horizontal pygidium.

P. georgianus.—Rather stout and convex, shining, subimpunctate, the

body, legs and antenne throughout rufo-testaceous, the abdomen blackish;

vestiture rather sparse, appressed, rather longer and less squamiform than

usual, pale luteous-white and conspicuous. Head not distinctly narrower

than the prothorax, slightly wider than long, the eyes very large and promi-

nent, separated by scarcely three times their own width; frontal longitudinal

furrow long and. distinct, the fovese normal, the apical the smallest of the

three. Antenne long and rather slender, fully as long as the head, prothorax

and elytra combined, the funicle only slightly incrassate distally, the last

joint fully as long as the three preceding, slightly swollen and obliquely

pointed toward tip and almost twice as wide as the tenth; fifth joint much

elongated, rather longer than the fourth, distinctly longer than the sixth

and only a little shorter than the third; tenth distinctly elongate and as

long as the ninth. Prothorax relatively rather small, 44 wider than long,

parallel, narrowed near the apex, the latter broad and transverse; median

fovea extending rather beyond the middle. lytra large and well developed,

almost fully as long as wide, much longer than the head and prothorax and

rather more than twice as wide as the latter, the sides somewhat strongly:

divergent and nearly straight from the moderately developed humeral swell-

ing, broadly arcuate in apical half, the apex somewhat narrower than the ante-

apical width; strise normal. Abdomen barely as wide as the elytra and much

shorter. Length 1.75 mm.; width 0.73 mm.

Georgia.

The unusually small head and prothorax, large elytra and pale

coloration distinguish this species from piceus,and, from the two

preceding species, it may be known immediately by the antennal

structure. <A single male.

. P.piceus of LeConte, is represented in my cabinet only from

Pennsylvania, and is apparently confined to the northern mari-

time provinces of the Atlantic coast fauna. It is, when mature,

of a dark rufo-piceous tint with the usual black abdomen of this

section of the genus, and is identifiable by its short and decidedly

transverse elytra, even in the male, and by the small fifth antennal

joint of that sex, this being notably shorter than either of those

which adjoin it; the antenne are rather shorter than in any of

the three preceding species.. The prothorax is but little wider

than long and is narrowed anteriorly from near the middle, differ-

ing in this respect from those most closely allied, and the vertexal —

fovese are more widely separated than usual. ;

P. iowensis.—Nearly similar in form and coloration to granicollis,

the antenne less pale and the pronotum smooth, highly polished and devoid

of granuliform punctures; pubescence sparse. Head only slightly wider than

Iowa (Keokuk).

Differs from granicollis in its shorter antenne, smaller, less

transverse and smooth prothorax,in the form of the discal stria

of the elytra and smoother and more polished integuments; from

piceus, it may be distinguished by the characters of the table.

P. granicollis.—Moderately stout and convex, piceo-rufous, the abdo-

men blackish, impunctate except the pronotum, which is sparsely granulose;

pubescence as-in the preceding species. Head well developed, much wider

long as the body excepting the abdomen, pale rufous throughout, only moder-

ately incrassate toward tip, the tenth joint but little longer than wide and

somewhat shorter than the ninth. Prothorar well developed, fully 14 wider

than long, distinctly more than 14 as wide as the elytra, narrowed only near

the apex; median fovea not extending quite to the middle. Elytra, only -

slightly shorter than wide, the sides rather strongly divergent from the broadly

and moderately swollen humeri, becoming arcuate toward tip; strice coarse,

the discal expanding and disappearing before the apex. Abdomen a little nar-

rower and much shorter than the elytra. Length 1.7-1.8 mm.; width 0.7-

0.8 mm.

New York (Willets Point, Long Island).

The female is much larger and stouter than the male described

above, with the antenne 3 as long as the body, the eyes smaller,

the foveze more widely separated, the prothorax relatively a little

smaller and with more obsolete sculpture, the elytra shorter, trans-

verse, with more rapidly diverging and straighter sides and the

abdomen very broad with arcuate sides, wider than the elytra and

fully aslong. It may be distinguished from piceus by the larger

head, larger, granulose and more transverse prothorax and less ab-

breviated elytra.

P. floridanus.—Rather stout, the upper surface only moderately con-

vex, subimpunctate and rather shining throughout ; body, legs and antenne

dark rufo-testaceous, the abdomen black ; vestiture appressed, moderate in

length, coarse, pale, somewhat abundant and distinct. Head about as wide as

the prothorax, slightly wider than long, the eyes large and very prominent,

separated by about 21% times their own width ; fovee normal. Antenne long

and rather slender, only just visibly incrassate toward tip, a little longer than

the head, prothorax and elytra combined ; eleventh joint fully three times as

long as wide ; tenth elongate and equal to the ninth. Prothoraz nearly 14

wider than long, parallel, abruptly narrowed only very near the apex, the

latter very broadly and transversely truncate ; surface minutely, feebly and

sparsely asperato-punctulate ; foveee normal. lytra well developed, as long

as the head and prothorax and obviously less than twice as wide as the latter,

nearly as long as wide ; humeral swelling scarcely at all prominent, the sides

strongly divergent almost from the base and nearly straight, becoming broadly

arcuate in apical half ; striae moderate, the discal not attaining the apex and

only feebly arcuate. Abdomen as wide as the elytra but much _ shorter.

Length 1.75 mm.; width 0.7 mm.

This species is rather closely allied to granicollis, but differs in

the much less thickened apical parts of the antennz, smoother

pronotum and more broadly squamiform vestiture of the ventral.

segments. I have not seen the female.

624 Coleopterological Notices, VII.

In the male of P. zimmermanni Lec., the body is very de-

cidedly narrower, as well as smaller, than in any of those which

precede, and is pale in color throughout including the abdomen ;

the vestiture is sparse but rather long, and is appressed as usual,

the hairs stout but scarcely squamiform. 'The antenne are quite

slender, but the eleventh joint becomes twice as wide as the

second; the ninth and tenth joints are elongate, subequal and de-

cidedly longer than any of the preceding. The prothorax is

barely as wide as the head, somewhat transverse and rather more

than 4 as wide as the elytra. In my previous table of this genus

(Col. Not. V, p. 501), the antennal characters should refer to the

female and not to the male; in the latter sex the last joint is

barely as long as the preceding three combined as usual. The

specimens in my cabinet are from Louisiana.

P. cinderella.—Rather slender and moderately convex, polished and

impunctate throughout; body, legs and antenne pale rufo-testaceous in color,

the abdomen barely distinguishably less clear; pubescence rather abundant,

appressed as usual, only moderate in length but subsquamiform and distinct.

Head and prothorax relatively rather large, equal in width, the former slightly

wider than long, the eyes only moderately large but convex and prominent,

separated by a little more than three times their own width; fovez small,

equal, forming a small equilateral triangle; antennal tubercles moderate in

width, the longitudinal sulcus subobsolete. Antenne slender; joints three to

seven elongate, the remainder missing in the type. Prothorar nearly % wider

than long, only slightly more than 14 as wide as the elytra, parallel, narrowed

slightly near the apex, the latter very broad and transversely truncate; median

fovea large, extending through basal 7 of the length. lytra conspicuously

short, fully 14 wider than long, the sides rather strongly divergent and feebly

arcuate from the moderate and obtuse humeral swelling; surface moderately

convex, the striz normal, the discal rather feeble, becoming obsolete at some —

distance from the apex. Abdomen as wide as the elytra and very nearly as

long, the sides parallel and rounded. Legs slender, the hind tibie slightly

swollen near the tip but not distinctly bent. Length 1.28 mm.; width 0.52

mm.

Texas (Brownsville). Mr. H. F. Wickham. |

This is the smallest species of the genus known to me from the

United States, and occurs in the subtropical extreme southern

limit of the State of Texas. It can be readily determined by the

characters given in the table. A single male.

P.impressipennis.—Slender, the elytraand abdomen quite depressed ;

rower than the prothorax, about as long as wide, triangular, the eyes relatively

rather small. Antenne normal, rapidly incrassate at tip, about 14 as long as

the body. Prothorax more than 14 wider than long, fully % as wide as the

elytra, parallel, slightly narrowed at apex; surface convex, smooth and pol-

ished, the median fovea extending only slightly beyond basal third. Elytra

nearly 14 wider than long, the sides distinctly divergent and only very feebly

arcuate from the rather pronounced humeral swelling; disk depressed, ob-

liquely impressed at the middle toward the flanks; strize normal, the discal

distinctly abbreviated before the tip. Abdomen somewhat wider than the

elytra and quite distinctly longer, the legs slender. Length 1.35 mm.; width

0.55 mm.

Texas (locality unrecorded).

The single example of this very distinct form before me is a

female, and it is the only species represented by that sex alone

which I can venture to define. The singular oblique impressions

of the elytra are without much doubt normal, as they are bilater-

ally symmetric. :

P, consobrinus of LeConte, is well distinguished from any of

those treated of above by its denser vestiture, relatively shorter

last antennal joint and other characters. The sexual differences

in the antennz, eyes and elytra are of the same nature as in the

others, but the elytra differ more than usual, being very short and

transverse in the female, while in the male they are nearly as long

as wide. My specimens are from New Jersey and Virginia (Nor-

folk). | :

In pulvereus Lec., the eyes in the male are much smaller than

in the same sex of any other species known to me, and it may be

readily recognized by this character as well as by its large size

and habitat. Ocularis and abruptus have already been described

at sufficient length (Col. Not. V, p. 502).

TYRINI. |

CEDIUS Lec.

In this well-marked genus the body is rather stout and very

convex, the antenne enlarged distally, the eighth joint obliquely

produced and pointed within at tip, partially enclosing the ninth,

the remainder gradually enlarged but not obviously modified, the

eleventh affixed somewhat obliquely to the tenth. The head is

nearly as in Pilopius, with moderately large, subbasal and more

finely faceted eyes and three fovex, the posterior much more

626 Coleopterological Notices, VII.

widely separated, the antennal tubercles large, separated by a

broad longitudinal depression which is much more abruptly lim-

ited at the sides; in spznosus the tubercles become more flattened.

The integuments are nearly smooth, the pronotum traversed near

the base by a fine continuous furrow, with slight enlargements at

the sides and in the middle but not pubescent. The discal furrow

of the elytra vanishes behind the middle, and the basal segment

of the abdomen has two distinct sublateral carinze in about basal

half and a short tumid projection at the middle of the base. The

ventral segments diminish rather gradually in length as in Pilo-

pius, but the last ventral of the male is large, convex and polished,

with the tip produced slightly in a rounded lobe, the last dorsal

short and very tumid. There seem to be three species which may

be defined as follows from the males :—

Head transversely excavated at apex between the large antennal cavities, the

narrowed front deflexed, with the tip narrowly rounded and free ; clypeus

tumid and setose at the middle; body large.and stout.

Antenne much less stout, distinctly enlarged toward tip ; elytra transverse,

at least 14 wider than long, rather strongly, though not densely, punc-

tate, and wider than the abdomen, the side margin of the latter concave

_ Antenne stouter and longer, only very feebly enlarged toward tip ; elytra

larger and less transverse, scarcely 14 wider than long, very finely and

rather sparsely punctulate throughout, the vestiture a little shorter ; ab-

domen as wide as the elytra, with the broad and feebly inclined lateral

margin perfectly flat throughout ; anterior tibie thicker ; body larger and

much stouter, nearly similar in the crural spines and feeble sexual char-

acters. Length 2.5 mm.; width1.0mm. District of Columbia.

robustus n. sp.

Head not transversely excavated at apex, the narrowed front. between the an-

tennal cavities vertical and continuous to the upper surface of the clypeus,

which is not at all tumid in the middle ; body much smaller and narrower.

spinosus Lec.

The tarsi in Cedius are much longer than in either Tmesiphorus

or Pilopius. The genus seems to be confined to the eastern parts

of the United States. |

The figure of C. spinosus given by Dr. Brendel in the “ Mono-

graph,’ is not at all correct, the true form-being much narrower,

with more elongate elytra and with the usual two carine of the

abdomen as distinct as in the others.

Coleopterological Notices, VII. 627

TYRUS Aubé.

In this genus the peculiar internal prominence of the trochan-

ters and the carina or spine of the anterior femur, are not sexual

characters, but are equally pronounced in the female, which, it will

be observed, is the case also in all the allies of Ctenistes and

Chennium, so that crural modification in this part of the family

becomes of generic import. As in most of these genera, also, the

species are closely allied among themselves and require careful

study. |

The primary sexual characters are rather feeble, the male ag

ing the last ventral moderate in size, with the apex produced

slightly in a rounded lobe and the last dorsal large, broadly trun-

cate and medially feebly sinuate at tip; the female has the last

ventral shorter, with the apex narrowly and deeply inciso-sinuate

in the middle, and the last dorsal much smaller, more tumid along

the middle and frequently more coarsely punctured, these sexual

differences in the last dorsal being parallel to those of certain

Batrisi. No well-marked sexual differences can be observed ‘in

any other part of the body or appendages.

The material in my cabinet indicates five North American spe-

cies, which may be defined as follows :— | |

Carina of the anterior femur long, equaling 4 of the entirelength. Utah.

carinifer n. sp.

Carina short, never more than 4 as long as the femur and sometimes a little

shorter.

Elytra large, about as long as the abdomen, very widely exposed at the

teriorly; head small; body pale testaceous with the abdomen black. Lake

T. elongatus of Brendel, does not belong to the genus and is >

therefore not included in the table. The American species of Ty-

rus all differ greatly from the European in having the anterior

femora carinate beneath; mucronatus has, instead of the carina,

an acutely pointed spine; it is therefore possible that Pytna may

be regarded as a valid subgenus, in view of the importance of

crural modifications in this part of the Pselaphide. -

T. carinifer.—Stout and convex, the body, legs and antennz very pale

rufo-testaceous throughout, the abdomen black with palish side margins; in-

teguments shining, subimpunctate anteriorly, the elytra and abdomen finely

punctate; pubescence moderately abundant, rather short and strongly recurved

as usual. Head scarcely as long as wide, only slightly narrower but much

shorter than the prothorax, the eyes moderate in size, at more than their own

length from the base, the latter rounded; surface flattened above, the fovece

normal. _ Antennx about 144 as long as the body, moderately stout, the club

gradually formed and not very stout; joints three to five distinctly, six and

seven barely perceptibly, longer than wide, the eighth quadrate; ninth slightly

elongate, the tenth almost as wide as long; eleventh obliquely pointed at tip.

Prothorax very slightly longer than wide, widest and obtusely rounded at the

sides before the middle, the sides thence convergent and nearly straight to the

apex, parallel and feebly sinuate to the base; apex nearly 24 of the maximum

width and about % as wide as the base; disk very convex, with a deep rounded

and pubescent fovea at each side near the base, the two connected by a fine,

transverse and posteriorly arcuate groove, which become slightly coarser but

not at all foveate at the middle, the surface thence to the base punctulate.

Elytra 3% wider than long, % longer than the prothorax and 2% times as wide;

humeri rounded, the sides thence rather strongly divergent and very feebly

arcuate to the apex ; discal impression very large toward base, disappearing

near apical third. Abdomen rather wider and a little longer than the elytra,

arcuately narrowed and serrate at the sides as usual, the border wide and flat;

basal carina well developed, extending to apical third of the basal segment.

Utah (southwestern). Mr. C.J. Weidt.

The single male before me represents a very clistinct form near

corticinus, but with a much larger head, narrower and more

elongate prothorax, more diverging sides and more punctate sur-

face of the elytra and relatively larger abdomen. The inter-

mediate tibie are slightly arcuate and somewhat thickened, the

corresponding trochanters with the usual long oblique process, the

anterior with a short conical process, and the anterior femora with

a long carina on the under edge, extending from basal fourth to

the middle. oe

T. semiruber.— Moderately stout and convex, highly polished, dark red-

brown, the elytra pale rufous, the abdomen black and the legs and antennz

pale testaceous; integuments subimpunctate, the punctules of the elytra and

abdomen extremely minute and rather sparse; pubescence moderately short,

rather fine, sparse, strongly recurved and not very conspicuous. Head small,

_ distinctly narrower and shorter than the prothorax, shorter than wide, the

eyes rather small, at more than their own length from the base, the latter cir-

cularly rounded; fovee normal. Antenne scarcely 14 as long as the body, un-

gose; three to five distinctly elongate, the sixth slightly and the eighth just

visibly, longer than wide; seventh quadrate; ninth very distinctly elongate,

the tenth rather longer than wide; eleventh obliquely pointed as usual. Pro-

thorax not quite as long as wide, widest and subprominently rounded near apical

third, the sides feebly convergent and somewhat sinuate thence to the base;

longer than the prothorax, the sides parallel and arcuate; border wide and flat;

basal carina well developed in basal 35. Length 1.7 mm.; width 0.78 mm.

Lake Superior.

The single male tvpe in my cabinet has the intermediate tro-

chanters obliquely prolonged in a shorter, more pointed and less

curved process than in the preceding, the tibize arcuate and thick-

ened, the anterior trochanters prominent within at tip and the

femur with a strong but short inferior carina just behind the mid-

dle. The body is narrower, the antenne shorter and more slender,

the prothorax shorter and broader, the elytra less transverse and

with longer discal stria, and the integuments less punctured and

less densely pubescent than in humeralis.

T. consimilis.—Stout and convex, shining and subimpunctate ; body,

legs and antenne red-brown, the elytra paler, bright rufous, the abdomen

black ; pubescence rather long, abundant, recurved and conspicuous. Head

Kentucky; Indiana.

The specimens before me agree very well together, but are fe-

males; in comparison with the same sex of humeralis, this species

differs in its longer and more shaggy pubescence, evidently shorter

antenne, smaller and relatively much shorter prothorax, more

abbreviated abdominal carina, and in some other features; the mod-

ifications of the legs and trochanters are of the same general kind

as in the other species, but the process of the middle trochanters

is shorter and broader than in humeralis, and the corresponding

tibize are quite different, being strongly, evenly arcuate through-

out in the latter, while in consimilis they are nearly straight to-

ward base, becoming gradually distinctly arcuate thence to the tip.

The specimens of humeralis in my cabinet are from Canada

(Ottawa—Mr. W. H. Harrington) and the Hudson River valley,

the latter taken by Mr. H. H. Smith.

CUCUJID 2.

CoLYDIINZ.

ADITOMA 0. gen.

This genus is allied to Bitoma, but differs in the cylindrical and

scarcely at all depressed form of the body, with very different

sculpture, larger metasternum, convex and not flattened abdomen,

with the third suture strong, and the fourth segment flat and de-

flexed, the fifth concave, and in the radically different antennal

club. The single species is remarkable in having a large bifid

thoracic process, nearly covering and concealing the head.

A. bifida n. sp.—Elongate, parallel, cylindric, dark rufo-piceous in color

and highly polished. Head subtriangular with truncate apex, quite distinctly

narrower than the prothorax, depressed above, more deeply toward base, where

there is a short longitudinal medial groove in the more excavate portion; ver-

tex before the eyes slightly tumid, coarsely punctured and minutely setulose,

the apical margin of the front polished and sculptureless; remainder minutely

sculptured and opaque; supra-antennal ridges strong. “Antenne 11-jointed,

but little longer than the width of the head, thick, cylindric, the joints trans-

verse with very thick exposed pedicels; two basal joints thicker, the club small,

rounded, the tenth joint obtrapezoidal and slightly asymmetric, at apex nearly

twice as wide as the ninth, polished and sparsely setose like the preceding

joints; eleventh much narrower than tenth and barely as long, fused within

its apex, rounded at tip, paler and spongy in texture and with short but coarse

close-set hairs in addition to the sparse erect bristles. Labrum very short,

strongly transverse; mandibles small; eyes large, rounded, entire and basal,

the antennal grooves altogether obsolete; mentum rather large, transversely

subquadrate; ligula triangular, corneous; palpi rufous, similar, the labial a

little smaller, the fourth joint elongate-oval, as wide as the preceding, with

the obliquely truncate apex hollowed and spongy. Prothorax slightly elongate, .

very convex with a coarse deep median groove which is dilated anteriorly in a

large and deep excavation and slightly dilated also at the base, the polished

surface enclosing the groove prolonged anteriorly over the head in two porrect

processes, finely, sparsely punctate, each puncture with a minute seta, the setz

more evident at the apices of the processes; flanks above strongly declivous to

a deep groove adjoining the acute lateral margin, which groove is dilated in a

rounded excavation just behind the middle; lateral margins nearly straight,

feebly convergent from apex to base, the apical angles dentiform and everted;

basal angles acute and slightly prominent. Scutellum small, subquadrate.

Elytra about twice as long as wide and twice as long as the prothorax, not

wider than the apex of the latter but a little wider than the base, the sides

straight and parallel; apex semicircularly obtuse; surface evenly cylindrical,

impressed at the sides near the apex, with nine coarse even and feebly im-

pressed series of coarse perforate punctures, the sutural stria enlarged and

deeper toward tip, becoming confluent with the subapical depression at the

side, the coarse punctures nude but alternating with minute punctures, each of

which bears a minute hair. Prosternum long before the coxze, the latter

moderately and almost equally separated throughout; anterior cavities open

behind. Legs very short and stout; tarsi short with the basal joint small.

Length 2.9 mm.; width 0.75 mm.

No indication of sex can be observed in the single specimen

before me, which was communicated by Mr. H. F. Wickham.

BITOMA Herbst.

Ditoma Ill.; Synchytodes Cr.

The following species is allied to ornata:—

_B. suffusa n. sp.—Elongate, strongly depressed, opaque, dark rufo-

piceous, the elytra suffusedly pale rufous but darker near the suture and lateral

margin; pubescence short, sparse, setiform, forming even recumbent series

along the ridges. Head rather small, 24 as wide as the prothorax, subquad-

rate, the eyes large, convex and prominent, occupying basal half; surface flat

and densely sculptured; antennz about as long as the width across the eyes,

the funicle slender, the club stout, compressed and very abrupt, with the two

joints subequal. Prothorax scarcely 4% wider than long, the sides feebly con-

vergent and feebly, evenly arcuate from apex to base; apex truncate, the

angles somewhat anteriorly prominent; basal angles obtuse; margins minutely

-serrulate; base feebly arcuate; disk but feebly elevated, with a fine entire

raised line at some distance from the side margin, near which line externally

there is a short longitudinal groove; inner raised line of ornata extremely

feeble and not distinct much beyond the middle; middle parts toward base

‘with two feeble longitudinal depressions; sculpture dense and indistinct.

Scutellum small, transversely subquadrate. Elytra fully 34 longer than wide,

3 times as long as the prothorax and nearly 14 wider; sides straight and

parallel, the apex semicircular; surface of each with four fine entire ridges,

separated by double series of rather coarse elose-set punctures, the sutural ele-

vation bifurcate toward base. Under surface dark red-brown, with short,

coarse and rather sparse reclined hairs, the legs short and paler in color.

Length 2.3-2.8 mm.; width 0.65-0.85 mm.

Arizona (Yuma).

Rather abundant in the lower valley of the Colorado River. It

is allied closely to ornata, but differs in its narrower form, suffused

coloration of the elytra, less distinct ridges of the pronotum and

in its much larger eyes.

The name Bitoma is used on the authority of Dr. Sharp, though

according to Seidlitz (Faun. Balt. ii, p. 234), it was applied by

Herbst to the Fabrician Lyctus; if so, Ditoma IIl., will be the

proper designation of the present genus.

EUCICONES Sharp.

The species at present in our lists under the name Cvcones

lineaticollis Horn, differs generically from marginalis in having

the upper surface feebly costulate and devoid of erect bristles,

and in having a distinctly biarticulate antennal club. The genus

has been named Acolobicus by Dr. Sharp, and the Mexican species,

obscurus Shp., seems to be extremely closely related to lineaticollis.

Cicones marginals is also regarded as generically different from

Cicones, and must be known henceforth as Eucicones.

The material in my cabinet appears to indicate two species,

which may be separated on the following general characters:—

Body more than twice as long as wide, subparallel, the elytra relatively more

broadly reflexed at the sides, with the humeri quite broadly rounded.

marginalis Melsh.

Body not more than twice as long as wide and much more dilated behind, the

elytra more narrowly reflexed at the sides, with the humeri much less

rounded Clavale DriSt es tMer ti. Gas sewedecs sews ss sss cameos sero latus n. sp.

The upper surface of the body in Eucicones is always varie-

gated with small irregular paler spots. The genus extends far

into Mexico, from which region the generic type has been recently

described by Dr. Sharp.

Coleopterological Notices, VII. 633

E. latus.—Broad and convex, oblong-oval in form, gradually broader to

apical third of the elytra, blackish and subopaque, the reflexed lateral margins

paler by diaphaneity; elytra with small anastomosing paler spots; erect

bristles moderate in thickness and but feebly clavate. Head wider than long,

scarcely more than % as wide as the prothorax, widest at base, the eyes rather

large, minutely setose; surface scabrous; antenne short. Prothoraxz fully twice

as wide as long, widest near basal third or fourth, the sides strongly arcuate,

more convergent anteriorly, the apex deeply emarginate and with distinct lim-

iting angles, 3 as wide as the base, the latter transverse, broadly arcuate,

broadly sinuate near the sides; surface broadly explanato-reflexed toward the

sides, densely tuberculato-scabrous throughout. Scutellum small. Elytra less’

than 14 longer than wide, at base as wide as the prothorax, at apical third much

wider, broadly parabolic at apex; sides nearly straight in basal 24 ; humeri ob-

tuse but distinct and subangulate; lateral margins narrowly explanato-re-

flexed; surface convex, with series of moderately coarse punctures separated in

the series by single short longitudinal raised lines, each of which bears a small

slender hair at its pos’erior end, the erect bristles borne from small subasperate

punctures extending in a single regular series along the middle of each inter-

val. Under surface scabrous and dull, with inconspicuous vestiture, the epi-

pleurze wide and concave, the abdomen flat with gradually diminishing seg-

ments to the fourth, the fifth as long as the first; sutures fine and perfectly

straight, the legs short. Length 3.4 mm.; width 1.75 mm.

Indiana ?

A single specimen was included without locality label in the

Levette cabinet, and was probably taken in the region suggested.

This species is notably broader than marginalis, and is more rap-

idly broader behind.

The clavate bristles in Eucicones are peculiar in structure; they

are deeply strigose, and the median parts of the apex are pro-

longed and obtusely truncate.

SOSYLUS Erichs.

_ §. extensus n. sp.—Elongate, parallel, cylindric, dark rufo-piceous, the

elytra slightly paler; surface feebly alutaceous in lustre, glabrous. /ead

slightly wider than long, not quite as wide as the prothorax ; eyes large, con-

vex and prominent, at scarcely 14 their length from the prothorax ; surface

moderately convex, finely, not very densely punctate ; antenne about as long

as the width across the eyes, the first joint swollen and subglobular, the second

elongate, slender and inserted at the side of the first, the club very stout and

abrupt, strongly compressed with the basal joint shorter than the second and

rather more than twice as wide as long. Prothorax distinctly longer than

wide, the sides straight and parallel in rather more than apical third, then

feebly convergent and straight to the base, which is nearly 4% as wide as the

apex, the latter transverse, becoming feebly arcuate toward the sides ; basal

angles not rounded, the base feebly emarginate ; disk finely, evenly and not

densely punctate. Elytra rather more than 3 times as long as wide, fully 244

times as. long as the prothorax and equal in width to the apical parts of the

latter ; sides straight and parallel; humeri slightly prominent anteriorly ;

apex near the suture narrowly arcuato-truncate, with slightly prominent

lateral limits ; surface feebly elevated near the suture, each elytron also having

four fine and very feeble longitudinal ridges, separated by three shallgw flat

and impunctate grooves, which are separated from each other by shallow flat

intervals equal in width to the grooves ; flanks also with shallow flat striz, the

third interval from the side margin with some elongate scratch-like punctures

toward base. Under surface with moderately close punctures, those of the ab-

domen very elongate and linear toward base. Length 4.65 mm.; width

0.8 mm. .

Central Texas (Colorado River).

This form is very different in sculpture from our other species,

but resembles certain Central American species in that feature.

The fine flat grooves of the elytra give these an appearance of

having been drawn like a wire; the ridges become quite strong on

the apical declivity as usual.

Extensus seems to be closely allied to affinis Shp., from Central

America, and also to trilineatus Reitt., from Colombia. The

latter differs in having the prothorax narrowed behind from the

middle and not from near apical third.

californicum Csy.

Unicolor appears to undoubtedly differ from castaneum in the

characters given above ; it is rather more elongate than castaneum

and the form of the scutellum is perfectly constant, as far as I

have been able to observe ; these species both occur in the Atlan-

tic States and westward, at least as far as Illinois. The Califor-

nian simplex is quite different in its much shorter and more con-

vex, though equally finely and sparsely punctate prothorax, and

the body is larger and stouter than in castaneum or unicolor with

more oval outline; in the scutellum and general sculpture it

closely resembles castaneum and sylvaticum; it seems to be con-

fined to the coast regions from Sta. Cruz northward. Under suit-

able amplification and direction of -sight extremely minute erect

setze can be observed arising from the punctures in nearly all of

the species, but californicum is the only one in which they become

very obvious, and this species differs besides from the others in its

much larger size. The three following species are hitherto unde-

scribed.

C. sylvaticum.—-Elongate, suboval, moderately depressed, polished,

dark rufo-castaneous, more blackish beneath, the legs and antennal club paler

and rufous. Head slightly more than 14 as wide as the prothorax, wider than

long, evenly convex, finely, sparsely punctate, the eyes minutely and sparsely

setulose; antennze moderate in length, the club paler. Prothorax quadrate,

widest at the middle, the sides parallel and feebly arcuate throughout,

rounded anteriorly; apex evenly emarginate in circular are and almost 44 as

wide as the base, the latter transverse, with the median lobe distinct though

broadly rounded; basal angles right and not sharply defined, being minutely

rounded; surface transversely and feebly convex, more distinctly so toward the

apex, transversely and quite distinctly impressed at the basal margin at each

side and also feebly impressed just behind the eyes at the apical margin; punc-

tures small and remote but rather strong, bearing minute erect setae remotely

interspersed with other erect setze which are coarser and longer, the set ob-

- servable under a power of about 80. Scutellum transversely oval, very broadly

rounded behind. ilytra about ?% longer than wide, not quite twice as long as

the prothorax and rather more than 14 wider, widest before the middle; sides

broadly arcuate; apex broadly parabolic; stris well impressed, finely punc-

tured, the intervals somewhat convex, the first depressed as usual toward tip,

the first stria closely approaching the suture posteriorly. Under surface finely

but strongly and rather sparsely punctured. Length 2.0 mm.; width 0.78 mm.

Idaho (Cceur d’Aléne); California (Lake Tahoe).

636 Coleopterological Notices, VII.

Closely allied to the eastern castaneum, but differing in its

slightly larger size, just visibly stouter and more convex form and

more marked punctuation ; it also differs in the slightly arcuate

and not rectilinear sides of the prothorax and in the form of the

terminal pygidium. The species can be distinguished at once

from simplex by its more elongate and more deeply striate elytra.

C. sticticum.—Oblong, parallel, strongly depressed, shining, castaneo-

rufous; the legs and antennal club. paler rufous; under surface slightly darker

and more piceous. Head perceptibly more than 14 as wide as the prothorax,

finely, sparsely punctate; antennze moderate in length, the joints 7-9 of the

funicle rather rapidly increasing in thickness, the latter perceptibly wider than

long; club strong, oval, moderately compressed, the basal joint occupying

more than 144 the length, the apical spongy portion apparently with an

imperfect median annulus of hairs. Prothorax not quite as long as wide, dis-

tinctly widest at about apical fourth, the sides thence very feebly convergent

and just visibly arcuate to very near the basal angles, where there is a feeble

sinuation, strongly rounded at apex, the basal angles just visibly everted, not

rounded; apex barely more than °4 as wide as the base, feebly emarginate in

circular arc; base very feebly arcuate, the median lobe scarcely differentiated ;

disk depressed, convex toward the apical angles, rather sparsely, somewhat

coarsely and strongly punctate, feebly impressed and more densely punctate

at each side at the basal margin; sete inconspicuous, even undera power of 80.

Scutellum longer than in castaxeum and more subangularly rounded behind,

transverse and flat. Elytra but slightly more than 13 longer than wide, fully

34 longer than the prothorax but not evidently wider, widest before the mid-

dle, the sides very feebly arcuate; apex semicircularly rounded; humeral

angles acute and minutely everted; strice rather fine but strong, evidently

punctured, the first approaching the suture posteriorly, the sutural interval

strongly depressed toward tip. Under surface evidently and rather closely

punctured, the legs stout. Length 2.6 mm.; width 0.85 mm.

Iowa (Iowa City).

The points of difference between this species and those of the

castaneum group are numerous and well marked; the prothorax,

for example, being as wide as the elytra and of a different form,

with much larger and deeper punctures, and the last three joints

of the antennal funicle are gradually wider, while in castaneum

the joints 3-8 are equal in width, 9 being larger and obtrapezoidal ;

the annuli of hairs toward the apex of the club are also much more

marked than in castaneum.

C. clypeale.—Oblong-elongate, parallel, strongly depressed, polished,

glabrous, dark rufous in color, the legs but slightly paler and the under sur-

face somewhat darker; setze entirely inconspicuous. Head 3 as wide as the

prothorax, rather strongly convex, very minutely and quite sparsely punctate;

Coleopterological Notices, VII. 637

eyes moderately large, very convex, prominent and finely faceted as usual; anten-

ne moderate in length, stout, the three outer joints of the funicle gradually

thicker, the club stout, oval, of the usual structure and paler in color. Pro-

thorax scarcely as long as wide, widest before apical third, the sides broadly

rounding to the obtuse apical angles, very feebly arcuate posteriorly, the basal

angles minutely and just perceptibly everted, not blunt; apex broadly emargin-

ate in circular arc, about #5 as wide as the base, the latter transverse and feebly

bisinuate; surface sparsely and rather finely but strongly punctate, very feebly

impressed at the sinuous parts of the basal margin. Scutellum very short and

transverse, very broadly rounded behind as in castaneum. Elytra % longer

than wide, more than 84 longer than the prothorax, and not obviously wider,

widest before the middle, where the sides are distinctly arcuate, quite dis-

tinectly narrowed pusteriorly, the apex subcircular in curvature; humeri acute,

minutely everted; striz fine but distinct, very finely, remotely punctato-cren-

ulate; intervals nearly flat, the sutural narrower and depressed toward tip.

Under surface rather sparsely and not very strongly punctured, the legs short

and very stout, the tibie elongato-triangular. Length 2.35-2.45 mm.; width

0.75-0.8 mm.

Kansas.

This distinct species may be identified at once by its deeply

and narrowly notched clypeus. In general form it closely re-

sembles stzcficum, but may be known by its more elongate elytra

and finer pronotal punctures ; the shape of the prothorax is also

different, being widest at a point less apical, with the sides more

arcuate posteriorly and the apex broader. It is represented in

my cabinet by two specimens.

NortrEs.—<According to Dr. Sharp it is probable that Synchita granulata Say,

and allied species will have to be referred to the genus Endeitoma.

The species placed in Machlotes in our lists must be referred to Prolyctus

CUPESID 4.

CUPES Fabr.

The four species of this remarkable genus which are known to

me may be differentiated among themselves quite readily as

follows :—

Supra-antennal tumid surface rounded and convex ; antennze shorter ; tempora

more developed behind the eyes, which are usually smaller.

Body black, the head pale and ochreous-yellow in color ; punctures of the

elytral series very large, deep and quadrate............... capitatus Fabr.

Body ochreous, the elytra variegated with confused patches of dark piceous-

brown ; punctures of the elytral series much smaller ....... lobiceps Lec.

The affinities of Cupes are very obscure, but certain structures,

as for example the reception of the acute prosternal process ina

deep pit of the mesosternum, proclaim its marked serricorn rela-

tionship.

C. oculatus.—Form nearly as in concolor but less elongate, pale yellow-

ish-brown with indefinite sublineate spots of dark brown on the elytra; integu-

ments throughout densely scaly. Head scarcely wider than the prothorax ;

sides above near the eyes longitudinally tumid, the elevation divided trans-

versely at the anterior limit of the very large convex eyes ; median line fine,

coarse anteriorly ; tempora very short. Prothorax fully 34 wider than long,

rectangular at apical fourth, the sides thence deeply sinuate and strongly con-

vergent to the apex, parallel and nearly straight in basal 34, becoming feebly

convergent and arcuate toward base ; disk elevated along the middle, with a

fine median line, broadly reflexed at the sides, also deeply concave at each side

of the middle. Scutellum well developed, rounded. Eiytra 234 to nearly 3

times as long as wide, parallel and straight at the sides, gradually narrowed

at apex, distinctly wider than the head ; ridges feeble, the second and third

alone distinct. Under surface densely scaly. Length 8.5-9.7 mm.; width

2.0-2.2 mm.

Indiana.

Differs strikingly from concolor in sculpture and in its less

elongate and rather more depressed elytra, with subobsolete first

costa.

The eyes in Cupes are very convex and composed of extremely

minute lenses; the outer surface of the eye is perfectly smooth

and unbroken, the lenses shining through from the inner surface

of the external shell. I do not remember having observed this

peculiar structure in any other type of the Coleoptera, but it is

probably not altogether confined to the present genus.

LUCANID &.

PLATYCERUS Geoff. (auct.).

SYSTENOCERUS Weise.

The first species described below is allied in coloration, general

sculpture and structure of the antennal club to oregonensis, but

is much smaller; the second is more closely related to depressus.

Coleopterological Notices, VII. 639

P. chalybeus n. sp.—Subparallel, strongly convex, glabrous, black, the

legs and abdomen piceous, the elytra with a dark steel-blue lustre; integuments

but slightly alutaceous. Head scarcely 23 as wide as the prothorax, trans-

‘verse, sparsely but distinctly punctured, the eyes moderate; front broadly con-

cave; mandibles small, arcuate, setose internally, with a large quadrate tooth

within at base, the apex almost equally trilobed, the upper lobe most acute.

Antennx moderate, the club 4-jointed, twice as long as the funicle; joints two

to five of the latter gradually and slightly increasing in width, the latter %

as wide as the first joint of the club, which is three times as wide as long and

‘scarcely 144 as long and % as wideas the second; last three joints much more

densely pubescent, subequal in width, nearly as in oregonensis. Prothorax %

wider than long, widest and subangularly rounded at the sides at basal third,

the sides thence convergent and sinuate to the basal angles, which are right,

only slightly blunt, prominent and slightly everted; sides less convergent and

nearly straight in apical #4; apex broadly and bisinuately emarginate, the

apical angles slightly prominent anteriorly; disk feebly impressed along the

‘middle, sparsely, somewhat unevenly and not very strongly punctate. Scutel-

times as long as the prothorax and perceptibly wider; intra-humeral impress-

ion small but distinct; punctures disposed nearly as in oregonensis. Legs mod-

erate in length, rather slender, the hind tarsi but little shorter than the tibiz.

Length ¢ 8.3-9.5, @ 10.3 mm.; width ¢ 2.8-3.5, 9 4.1 mm.

California.

This species greatly resembles oregonensis, but differs in its

much smaller size, smaller head, prothorax and mandibles of the

male, rather stronger and sparser punctures, and especially in the

prominent basal angles of the prothorax, these being broadly ob-

tuse and obliterated in oregonensis. The description is from the

larger of the two males before me, the female having the head

relatively smaller, the prothorax narrower but less transverse

and more narrowed toward tip, the body stouter and the hind

tarsi scarcely 2 as long as the tibia.

P. marginalis n. sp.—Oblong, parallel, noderately convex, glabrous, the

‘punctures of the head with very short hairs, the mandibles setose within and

the side-margins of the prothorax bristling with rather numerous erect sete;

body and legs black, the tarsi and antenne dark piceo-rufous; integuments

moderately shining, the elytra feebly alutaceous. Head moderately large, 24

as wide as the prothorax, strongly transverse, strongly and closely punctured,

the mandibles short and stout, with the apex within broadly truncate, the

truncature nearly straight, only feebly oblique and beset with about five small

denticles, of which the superior is slightly larger and more acute, the inner

basal tooth well developed and feebly bifid at tip. Antennz moderate, the

club unusually developed, fully twice as long as the stem, broad, composed of

four joints, the first only slightly shorter in a transverse sense than the others

640 Coleopterological Notices, VII.

and more than twice as wide as the last joint of the funicle. Prothorax nearly

4< wider than long, widest and obtusely angulate at the sides at basal 7, the

sides thence very feebly convergent and nearly straight, becoming arcuate near

the prominent but rounded apical angles anteriorly,and much more convergent,

‘becoming sinuate near the base posteriorly, the basal angles obtuse but promi-

nent and not blunt; surface transversely convex, broadly concave near the re-

flexed side-margins especially anteriorly, the punctures moderately coarse and

numerous but distinctly separated, becoming sparse or partially absent along

the median line and near the side-margius. Scutellum wholly impunctate.

Elytra short, scarcely % longer than wide, not obviously wider than the pro-

thorax and about 234 times as long, the apex semicircularly rounded; humeri

right and slightly denticulate, the intra-humeral impression feeble; striz

moderately coarse, rather feebly impressed, closely and strongly punctured,

subobliterated toward the humeri, stronger behind but wholly wanting be-

hind the rather pronounced subapical swelling; intervals closely and strongly

punctured, nearly flat, the punctures sparse and more serial toward the suture.

Legs rather slender, the hind tarsi distinctly shorter than the tibie. Length

10.9 mm.; width 4.1 mm.

Washington State.

The male type represents a species allied to depressus, but

smaller, shorter in form, with finer, more superficial and smoother

elytral sculpture, more concave and fimbriate margins of the pro-

thorax and blacker coloration.

PASSALINA.

Some years ago I received small sets of species in this sub-

family from two sources. The larger number were taken by Mr.

Erich Wittkugel in the vicinity of San Pedro Sula, Honduras, on

the Atlantic slope, and the remainder by Mr. Baron, in the Mexi-

ean state of Guerrero, on the Pacific side. Only one ofthe fifteen

species examined proves to be common to the two regions, indi-

cating in some degree the mutual distinctness of the Atlantic and

Pacific faunas even in this very constricted portion of the conti-

nent.

The arrangement of the genera proposed by Mr. Bates in the

“ Biologia,” which is based: primarily upon the relative size of the

prothorax and elytra, even should it prove not entirely natural,

is at least far more convenient than that of Kaup, the classifica-

tion of the latter being marred in addition by a most original and

unaccountable assumption, that each and every genus would be

found ultimately to be composed of five species. In some genera,

possessing a number of species, this premise even led Dr. Kaup

Coleopterological Notices, VII. 641

into flagrant errors of synonymy, due to his desire not to an-

nounce in any case more than the assumed five components.

The species composing the material before me are as follows:—

Proculus mniszechi Kaup.—Honduras.

Proculus magister sp. n.— Honduras.

Proculejoides crassulus sp. n.—Honduras.

Platyverres intermedius Kaup.—Guerrero. The single example is rather

small, not quite 42 mm. in length, 48 mm. being the length recorded

by Kaup. It is somewhat singular that the pronounced habital diver-

gence of intermedius from the other species placed in Verres, should not

have been alluded to by the author, and the necessity for a distinct

genus is sufficiently evident. It is probable that Dr. Kaup had in view

only the cephalic structure, which greatly resembles that of Verres, and

the short lobes of the antennal club, in associating it with Verres corti-

cola.

_ Rimor munitus sp. n.—Guerrero.

Paxillus parvus sp. n.—Honduras.

Neleus tlascala Perch.—Honduras.

Ninus interstitialis Esch.—Guerrero and Honduras. The male has the elytra

very slightly shorter and the prothorax a little longer, but not wider,

than the female. There is no distinguishing feature apparent in the

representatives of the two localities.

Rhodocanthopus inops Truq.—Guerrero.

Ptichopus angulatus Perch.—Honduras.

Passalus striatopunctatus Perch.—Honduras. Differs from distinctus and

cornutus in having the metasternum strongly punctured near the hind

angles, with the depressed lateral line wider and more pubescent, in

the large and prominent single external spine of the middle tibiz, and

especially, in the structure of the antennal club, the first joint being

fully three times as wide as long and of a different form. Some of these

differences are possibly subgeneric in weight.

Soranus imbellis sp. n.—Guerrero.

Verres corticola Truq.—Guerrero.

Verres vernicatus sp. n.— Honduras.

Verres cavilabris sp. n.—Honduras. i

The new species of the list are described below in the same suc-

cession.

Proculus magister.—Elongate-oval, strongly convex, polished, the

pubescent areas and general structure almost exactly as in mniszechi. Head

with three feeble tubercles, two of which are near the anterior margin,

and a large oblique tumidity above each eye, the neck densely punctured at

the sides of the upper surface; labrum a little larger than in mniszechi, rather

more deeply sinuate at apex and less densely punctured, the mandibles shorter

and stouter, more unequally bilobed at apex and much more convex externally

toward base, the upper tooth less basal, more oblique and much less developed;

642 Coleopterological Notices, VILLI.

mentum very nearly 14 as wide as the entire head, the lobes very strongly and

obliquely cariniform. Prothorax as in mniszechi, but with the apical angles a

little less rounded. /ytra suboval, more vertical at the sides than in mnis-

zechi and flattened above, finely and feebly striate, becoming deeply so inter-

nally; strie finely punctured toward the sides and apex, but impunctate, or

with the faintest trace of punctures, toward the suture. Under surface as in

mniszechi, except that the intermediate tibize generally have but two external

Spinules, the posterior one. Length of body ¢ 73.0; width of head 21.5;

length of prothorax 20.0, width 27.5; length of elytra 37.5, width 26.3 mm.

Length of body 9 66.0; width of head 20.0; length of prothorax 18.0, width

24.5; length of elytra 33.0, width 25.8 mm. Honduras.

Larger and more elongate than mniszecht and with notable di-

vergence in the structure of the mandibles, mentum and elytral

strie. The minute tubercles near the frontal margin are more

widely separated than in mniszechi, and, in that species, the men-

tum is smaller, being but slightly more than 4 as wide as the head

and the elytra more evenly convex, with the striz not much deeper

toward the suture and having the strial punctures equally distinct

throughout. In magister the male is larger than the female, with

larger head and prothorax and notably more elongate elytra, while

in mniszechi the two sexes are much more similar in shape, the

head and prothorax of the male being simply a little larger. The

mandibles and antenne are not affected sexually. I have before

me both sexes of the two species here compared.

Proculejoides crassulus.—Stout and very convex, highly polished

throughout and deep black, the pubiferous punctures of the inflexed sides

of the prothorax fine and only moderately dense, wanting internally to-

ward apex; metasternum and elytra completely glabrous; tibie sparsely

pubescent externally. Head slightly more than % as wide as the pro-

thorax, the ambient posterior impression feeble ; horn narrow, small and

cariniform, with a small angulate and slightly prominent elevation at each

side, the tip horizontal and but just visibly protuberant over the frontal

impression, the latter limited by very broadly swollen, extremely widely

diverging and indefinitely limited ridges; clypeal margin straight and

transverse, with a minute and very feeble median sinus and ending at

lateral fourth in an acute tubercle, the margin thence angularly receding to

the eyes ; supra-ocular ridge large, cariniform above, longitudinally excavated

at its posterior end ; labrum sparsely punctured toward tip, the latter almost

rectilinear ; mandibles broadly angulate on the upper edge, the apex triden-

tate, with the two upper teeth much more advanced ; scar of the mentum

feebly defined ; antennal club trilobed, the lobes slender, the first joint 4 times

as wide as long, the second nearly similar, the third evenly arcuate externally,

3 times as wide as long. Prothorax slightly more than 14 wider than long,

the apical angles obtuse but only slightly rounded, the apex transverse ; mar-

ginal groove fine and wholly impunctate, extending inward at apex about %

the distance to the middle ; post-median impression feeble and impunctate ;

disk convex and wholly impunctate, the median groove strong. Scutellum

polished and wholly impunctate. lytra distinctly less than 144 longer than

wide, about *¢ longer than the prothorax, slightly dilated behind the middle,

the base transverse, feebly protuberant at the middle, the humeral angles

strongly defined, not at all rounded and but little more than right ; disk

coarsely and deeply striate throughout, the sulci strongly and equally punc-

tate throughout the width ; intervals convex. Metasternum short, without an’

elevated median plane, having a patch of coarse punctures at lateral fourth

near the hind margin and a small oblique posterior impression at each side of

the median line ; epipleurze extremely fine and wholly glabrous. Legs rather

short, the middle tibize with one very strong, the posterior also with a single

feebler, external spine. Length 24.0 mm.; width 9.0 mm.; length of the pro-

thorax 6.5, of the elytra 12.3mm. Honduras.

The genus Proculejoides is allied closely to Proculejus, differing

in its glabrous elytra and metasternum; it should probably include

also Proculejus championt of Bates, which differs from the present

species in its larger size and in Savi the frontal carine tuber-

culose far behind the apical margin.

Rimor munitus.—Parallel, rather strongly convex, deep black and

highly polished throughout, the basal wall of the elytra slightly pubescent at

the humeri ; metasternum and hypomera finely punctate and pubescent, the

former in a large lateral area from the middle coxe to the sides of the apex,

the latter glabrous anteriorly; tibie all rather conspicuously pubescent ex-

ternally. Head impunctate, #4 as wide as the prothorax, the posterior ambi-

ent excavation deep and impunctate, with a feeble elevation at each side near

the base of the horn, the latter large, elongate, convex, simple and finely punc-

tulate, with a minute longitudinal elevation at each side of the base, the apex

pointed and prolonged horizontally far over the front, the tip feebly reflexed,

and, from a vertical viewpoint, almost exactly over the apical margin of the

clypeus, the diverging elevations from the anterior part of its base very feeble

and rounded, flexing laterally to the supra-orbital ridge and forming the an-

terior limit of the posterior ambient impression; clypeal margin transverse,

broadly sinuate in the middle and separated from the front—which is nearly

flat and gradually declivous from the base of the horn—by a transverse mar-

ginal sulcus, ending immediately behind the ridge of the mandibles in a pro-

nounced angular protuberance, the sides of the clypeus proper marked also by

a slightly prominent angle at the sides of the labrum; supra-orbital ‘ridge large

and prominent, evenly convex and gradually disappearing behind, becoming

narrow and acutely cariniform anteriorly; canthus of the eyes rather wide;

labrum moderately sinuate at tip, the surface excavated and gradually beveled

in a broadly triangular region bordering the sinus; mandibles well developed,

the upper ridge angulate beyond the middle, the apex truncate and equally

tridentate, the inferior tooth well developed; mentum with the median part

of the base elevated, glabrous and impunctate, its flanking scars deep but only

slightly punctate; two basal lobes of the antennal club long and subequal,

about 5 times as long as the joint, the last jointabout 3214 times as wideas long,

the lobe widest beyond the middle. Prothorax about 14 wider than long, the

apex transverse and feebly bisinuate, the apical angles rather broadly rounded;

marginal groove fine and impunctate, extending inward at apex without the

least dilatation about % the distance to the middle; disk transversely convex,

wholly impunctate, the post-median lateral depression well marked though

smooth; median groove deep, terminating at some distance from the apical

margin. Scutellum sparsely punctate toward base, the median line im-

pressed except toward tip. Elytra about % longer than wide and nearly 2144

times as long as the prothorax, equal to the latter in width and with the sides

parallel and nearly straight, the apex circularly rounded; base broadly and

very feebly sinuato-truncate; disk rather deep and vertical at the sides, gradu-

ally less convex and horizontal above, the striz distinct and equaliy pro-

nounced throughout, only a little more widely separated above than on the

flanks, the punctures distinct on the flanks but very indistinct toward the

suture, the intervals broadly and equally convex throughout. Metasternum

well developed, the depressed side-pieces becoming broader behind, the sur-

face polished, without coarse punctures near the hind angles. Middle tibiz

with three external spines, gradually more pronounced distally, the hind tibie

with a single spine. Length 38.0 mm.; width 13.0 mm.; length of prothorax

9.0, of the elytra 21.0 mm. Guerrero. :

_ This species is closely allied to sagittarius, but differs in its

larger size and relatively shorter and more transverse prothorax;

the elytra are only twice as long as the prothorax in sagitiarius,

according to the measurements given by Dr. Kaup.

Paxillus parvus.—Elongate, rather narrow, depressed, the upper sur-

face flat, deep black and highly polished throughout, glabrous, the fine punc-

tures of the posterior parts of the hypomera and humeral part of the basal wall

of the elytra bearing very short erect hairs, the latter very dense, but not ex-

tending behind the humeri at the sides. Head nearly #6 as wide as the pro-

very fine, extending % the distance to the middle; median groove fine but

deep, very nearly attaining the apical margin. Scutellum impunctate, the

median line feebly impressed. lytra nearly #5 longer than wide, about 244

times as long as the prothorax, and, at base, equally wide, just visibly wider

behind the middle; base transversely rectilinear throughout; striz of the flat

upper parts rather fine but well impressed and very feebly punctate, the sec-

ond and third somewhat sinuous, the intervals relatively wide and feebly con-

vex, those of the vertical flanks very coarse, deep, approximate and sulciform,

with the punctures coarse. Metasternum witha strongly delimited median plate,

strongly punctured about the circumference on the sloping sides and very

densely near the middle cox, the episterna very narrow, linear, concave,

opaque and glabrous. Middle and hind tibiz each witha single small external

spine near apical third. Length 16.8-18.8 mm.; width 5.6-6.0 mm.; length of

the prothorax (in the smaller example) 4.0, of the elytra 9.7 mm. Honduras.

Differs from the Brazilian leach in its very much smaller size

and transverse and not visibly emarginate median parts of the

clypeal apex.

Soranus imbellis.—Rather elongate and strongly convex, glabrous,

black and highly polished throughout above. Head small, scarcely 34 as wide

as the prothorax, impunctate, the posterior ambient impression shallow pos-

teriorly where it is indefinitely limited, becoming larger and deep anteriorly

along the supra-orbital ridges, enclosing also a small deep rounded depression

at each side of the base of the central process, the latter transverse, rather small

and feebly elevated, almost equally trilobed by very feeble longitudinal de-

pressions, the lateral lobes rectangular at apex, the median.produced at tip in

a minute and nearly erect, acutely pointed process, from the base of which ex-

tend two very widely diverging, low, obtuse and straight ridges flexed outward

at apex, joining the supra-orbital ridgeand minutely tuberculate at the point of

flexure; front between the ridges very feebly concave to the straight and trans-

verse marginal sulcus, the latter terminating at each side in a small acute

tubercle directed obliquely upward and outward at the base of the mandibular

ridge; clypeal edge transverse and virtually straight, angular and slightly

prominent at each side of the labral base; supra-orbital elevation rather short,

cariniform anteriorly. Prothorax rather small, fully 144 wider than long, trans-

versely subarcuate at apex, the angles moderately rounded; raarginal groove

very fine, impunctate, flexed inward fully 144 the distance to the middle at

apex, receding gradually from the edge and becoming gradually more feeble;

post-median depression small but deep, coarsely punctate, the flanks with a few

coarse scattered punctures in its neighborhood; median groove strongly im-

pressed, entire. Scutellum impunctate, notimpressed. Elytra nearly * longer

veloped, punctured and pubescent near the middle coxe, but elsewhere com-

pletely impunctate and glabrous, the epipleure very fine, linear and deeply

Guerrero.

Differs from haagi and recticornis in its impunctate scutellum,

and from wagnerz in its straight and not arcuate frontal ridges;

tropicus, ellipticus, championi and yucatanus are much larger

species and intergeneus of Bates, which is doubtfully referred to

the genus, has the metasternum somewhat punctate at each side

of the apex. The type of the description is probably the female,

the male being nearly similar but with the prothorax a little more

transverse and about as wide as the elytra. Four specimens.

Verres vernicatus.— Parallel, moderately convex, polished and gla-

brous throughout above except some sparse short hairs distributed over the

vertical wall of the elytral base; pro- and mesosterna opaque and minutely

granulato-reticulate, except toward the lateral edges where the former is con-

spicuously pubescent as usual, the latter strongly and coarsely punctured at

the sides of the peduncle. Head nearly * as wide as the prothorax, the pos-

terior ambient impression deep, its posterior margin behind well defined and

broadly cuspid, broad and shallow anteriorly; central process transverse, form-

ing an anteriorly acute middle lobe and two obtusely rounded lateral lobes,

not separated by longitudinal impressions, the frontal ridges diverging ex-

tremely widely from a short distance before the base of the process, gradually

and arcuately becoming transverse and joining the supra-orbital elevation; they

are subacute, though feeble, and are feebly tuberculate at lateral third of the

entire width of the head; clypeus thence moderately declivous, smooth and

almost plane to the apex, which is subrectilinear, with a small median sinus

and limited at each side of the labrum by a moderately prominent angular

projection; from this projection proceeds a pronounced short longitudinal ele-

vation to the frontal ridge; supra-antennal elevation large and angularly

prominent anteriorly; labrum rather deeply sinuate in the middle at apex, the

surface adjoining the sinus deeply impressed and concave for a short distance.

Prothorax fully 44 wider than long, the apex slightly advanced in median %

and subrectilinearly truncate, thence obliquely subsinuate to the rounded

apical angles; marginal groove punctate, inflexed at apex less than half way

to the middle, becoming deeper though only slightly wider, with acutely

limited margins and strongly and transversely rugose bottom; post-median de-

pression rather small, smooth; disk impunctate throughout though with min-

ute scattered punctules, the median groove coarse and deep. Scutellum deeply

and closely punctured, with a smooth median line. Elytra but little more

than 144 longer than wide, not quite 244 times as long as the prothorax, just

visibly wider behind the middle, the striz moderately impressed and finely

punctured, the intervals feebly convex. Metasternum finely punctured and

pubescent toward the coxe and along the depressed epipleurz, which become

wider behind. ‘Tibiz distinctly pubescent, the middle and posterior without

trace of external spinules. Length 34.0-35.0 mm.; length of prothorax in.

duras.

Closely allied to corticola but shorter, with the elytra, especi-

ally, less elongate and distinguished besides by the smaller,

deeper and narrower apical concavity of the labrum, cariniform

lateral limits of the plane of the clypeus, which are wanting in

corticola, in the smaller cephalic process with smaller median pro-

tuberance and less angulate lateral lobes, in the deeper, longer

and strongly rugose apical part of the lateral thoracic groove, and

in many other features. The small clypeal projections in the

Guerrero examples of corticola before me, are much feebler and

more widely separated than in the figure of Kaup, this distance

being fully 4 the entire width of the head ; in the present species

it is even greater still. :

Verres cavilabris.—Parallel, rather stout and broadly convex, the

elytra deplanate above and rather abruptly but deeply vertical at the sides;

upper surface highly polished and glabrous throughout, except the short sparse

pubescence on the vertical wall of the elytral base. Head %4 as wide as the

prothorax, the upper surface somewhat as in the preceding species, except that

the posterior margin of the posterior ambient depression, which is broad, feeble

and indefinite throughout, seems to be indefinitely limited, the supra-orbital

ridges acutely carinate anteriorly and globularly dilated internally behind,

the central process much longer, with a long slender median projection, and

the lateral lobes more angulate, also in the form of the frontal ridge; the latter

is at a slight distance in front of the deep horizontal excavation extending

under the horn, and is transversely and feebly arcuate, ending, at lateral third

of the entire width of the head, in an abrupt and strongly marked tubercle and

not extending further toward the sides; the clypeus between this ridge and

the tip is rapidly declivous, the apical margin broadly emarginate, with a

broad and still more pronounced sinus at the middle, exposing a transversely

truncate pale coriaceous piece between the upper surface of the labrum and

under surface of the clypeus; the emargination nearly equals 4% of the entire

width of the head in extent, and is limited at each side by a prominent angu-

lar projection, not connected at all with the tubercle forming the extremity of

the transverse frontal ridge; labrum about as long as wide, rather deeply

sinuate at tip, the surface deeply and abruptly concave in a parabolic area ex-

tending to basal fourth and including the apical sinus anteriorly; mandibles

unusually developed. Prothorax about % wider than long, the apex much

advanced toward the middle and transverse at tip, very oblique and subsinu-

ate laterally to the broadly rounded angles; lateral groove obsoletely and re-

motely punctate, inflexed and greatly dilated at tip for scarcely % the distance

to the middle, the excavation moderately deep, punctured and rather abruptly

defined at its arcuate posterior and interior limit, but shallow, indefinite and

smooth anteriorly to the apical edge; post-median depression strong, transverse

and smooth; disk impunctate, evenly, transversely convex, the median groove

fine and feeble. Scutellum punctate, with an impunctate median line. Elytra

parallel, not swollen behind, 44 longer than wide, 214 times as long as the pro-

thorax, finely striate, more coarsely on the vertical flanks, where also the punc-

tures become more distinct and the intervals distinctly narrower and more

convex. Pro- and mesosterna opaque, the metasternum polished but punctu-

late and pubescent broadly at the sides throughout, with numerous coarse

punctures along the hind margin. Tibiz densely pubescent externally, with-

out trace of external spines. Length* 39.5 mm.; length of prothorax 9.5,

width 12.5; length of elytra 21.0, width 13.0 mm. Honduras.

This remarkable species is evidently somewhat related to

_hageni Kaup, but differs in its stouter form and in having the

end tubercles of the transversely arcuate frontal ridge perfectly

and abruptly isolated laterally, and not connected with the supra-

orbital ridge by a transverse elevation. From cavicollis of Bates,

to which it is very closely allied, it appears to differ in its still

larger labral excavation, shorter transverse frontal ridge and

shorter and more transverse joints of the antennal club. Mr.

Bates states with regard to cavicollis ‘‘ metasterno punctulato-pu-

bescenti, medio solum glabro;” in the present species the pubes-

cent and punctured surface is confined to the sides, broadly an-

teriorly but not extending inward beyond the depressed side-piece

posteriorly.

NotTE.—For several years past I have had two series of examples separated

under the name cornutus Fabr., the series differing from each other quite con-

spicuously in size and in the structure of the cephalic process. From all that I

have been able to gather, the smaller form occurs more especially on the eastern

slopes of the Appalachian system, while the larger occurs generally to the west-

ward, although there is without doubt a mixture of the two in the intervening

regions. The eastern form, which may be regarded as the true cornutus, has the

cephalic process somewhat variable but small, thickened at base and cylindri-

cally pointed at its porrect apex, while the western form not only has the bedy

larger and slightly more elongate, but the horn much larger, with the porrect

portion flattened and the transverse section near base nrore angulate at the

sides. Although there are absolutely no other differential features of note, it

seems nece:sary to consider these larger western forms, with more developed

corneous process, as at least a well-marked subspecies, which may be known

as distinctus Weber. |

*The measurements of length include the mandibles in all the above de-

scriptions.

Coleopterological Notices, VII. 649

The sexual differences in Passalus are extremely slight. For example, in

the typical cornutus, the male is a little larger than the female with the pro-

thorax wider and longer, about equaling the elytra in width, and the head is

more than 14 as wide as the elytra, with the horn moderately developed, while

_ the female has the prothorax noticeably narrower than the elytra, the latter

being more than twice as wide as the head, and the corneous process is very

small and narrow. The abdominal characters are precisely similar in the two

sexes, the marginal groove of the fifth segment being asexual in nature as in

Zopherus and some other types, and there are scarcely discernible differences

in the antenne, except that the first joint of the club is notably narrower than

the second in the female, but nearly equalin the male. In distinctus the sexual

differences are still less marked, there being no appreciable variation in the

corneous cephalic process ; in general form of body the male is but slightly

larger, though notably broader than the female. |

CEPHALOID.

CEPHALOON Newm.

The body in this very isolated type is elongate and convex,

with rather loose connective tissues as in Cistelidee, and, as in that

family, the claws are strongly pectinate; they are, however, more

largely developed than in Cistelidz, minutely pubescent and pro-

vided with a long, finely pubescent appendage ; there is a bisetose

onychium between them. The head is elongate, gradually and

obliquely narrowed behind the eyes, which are large, finely

faceted, deeply emarginate, anterior in position and minutely

setulose. The mentum is moderate in size, flat or concave, some-

what elongate-oval in form, truncate at apex and has its plane

much inclined to that of the narrow support; the maxille are very

large, prominently exposed at the sides of the mentum, the lobe

well developed, gradually acuminate and densely ciliate along its

inner edge. Ligula broad, with very large rounded paraglosse ;

labial palpi small, with the third joint triangular, compressed,

squarely truncate in are at apex. Maxillary palpi long and much

developed, the last joint dilated, very obliquely truncate and ex-

cavated at tip. Antenne inserted at the sides of the head before

the eyes under the acute side margins of the front, slender,

11-jointed, the last three joints broader or not, differing in form

and vestiture from the preceding joints and forming a feeble club.

Clypeus large and rather long, the suture fine but distinct. La-

brum long and greatly developed, the apex broadly and feebly bi-

lobed or sinuato-truncate. Mandibles long and arcuate but not

extending much beyond the labrum. Prothorax generally cam-

panulate, with everted basal angles, always distinctly narrower

than the elytra. Anterior and intermediate coxe very large and

greatly exposed, approximate, the anterior cavities large, conflu-

ent and very broadly open behind; posterior cox contiguous,

extending to the sides of the body. Metasternum large, the epi-

sterna broad, becoming narrower behind. Abdomen composed of

five free segments, the fifth emarginate at tip in both sexes, more

narrowly in the female; sutures straight. Legs long and very

slender; tibial spurs well developed, simple; tarsi slender,

cylindrical, the penultimate joint unmodified.

The characters of the family as given by LeConte and Horn

(Class. Col. N. A., 2ed., p. 405), are unaccountably erroneous and

misleading, it being stated, for example, that the eyes are small,

the frontal suture not distinct, the prothorax at base as wide as

the elytra, that the side-pieces of the metasternum are narrow,

and, finally, that the abdomen is composed of six free ventral seg-

ments, with the sixth short and deeply emarginate in the male.

The family should follow the Cistelide in our lists, and is out

of place in its present position near the Gidemeridz. The species

inhabiting the United States are at least five in number, and may

be readily differentiated as follows :—

Prothorax larger and more campanulate, fully as long as the head or longer

and much broader at base, the everted basal angles more developed ; an-

tenn shorter, the last three joints slightly dilated in the female, the

ninth and tenth not notably elongate; neck feebly but abruptly con-

stricted.

Antenne short, not as long as the head and prothorax, the three outer joints

distinctly wider, the eighth distinctly shorter and much narrower than the

C. versicolor.—Elongate, convex, alutaceous in lustre, minutely, closely

punctured and uniformly clothed with fine, short, pale and decumbent pubes-

cence throughout; body varying from blackish throughout, with the legs, front

parts of the head and basal and apical parts of the antennz paler, to pale tes-

taceous throughout, the apex of the femora, especially the posterior, generally

suffusedly darker and the tip of the tibie blackish; pronotum in intermediate

forms blackish, with the flanks, tip and median basal parts paler, or pale tes-

taceous throughout, with two discal blackish spots; elytral suture and basal

parts of the flanks frequently blackish. Head elongate, slightly more than 14

as wide as the base of the prothorax, the post-ocular portion feebly impressed

along the middle, conical with the sides feebly sinuate; neck abruptly but mod-

erately constricted; eyes large, separated by 14 of their own width. Antennz

about as long as the head and prothorax, the three outer joints very feebly

longer than wide and distinctly shorter than the eighth; eleventh elongate-

oval, about as long as the two preceding combined. Prothorax slightly elon-

the latter transverse with the sublateral sinuations feeble; sides rounded,

strongly convergent from near the middle; basal angles acute and strongly

basal width. lytra 3 times as long as wide, 43 wider than the prothorax and

more than 3 times as long; sides subparallel, gradually rounded and convergent

in apical fourth or more; apex of each evenly and rather narrowly rounded;

Four specimens are before me from the Levette cabinet, with-

dages, and the posterior margin of the third segment has a small

bifurcate process at the middle.-.

above and beneath, the flanks testaceous, the pale area extending obliquely in-

ward posteriorly to the median line near the base; basal parts blackish with a

large semi-isolated pale spot near each angle, a small spur of blackish from the

under surface also showing from above at the middle of the side margin; elytra

pale ochreous, the suture feebly blackish toward base; under surface blackish,

the mes-epimera and median parts of the abdomen pale; legs pale and colored

as in versicolor. Head elongate, the post-ocular portion conical, feebly impressed

toward the median line except toward base, and with the sides perfectly

CURCULIONID A.

BALANININI.

BALANINUS Germ.

The species having short beaks in both sexes are numerous

within the borders of the United States, and have been only

superficially elaborated thus far; the table given below is there-

fore confined to them alone. In the table published by Mr.

Blanchard (Bull. Bk. Ent. Soc., 1884, p. 106) this particular group

is represented by two species, obtusus and uniformis; confusor was

subsequently defined by Dr. Hamilton. Nine other species are

now added. The species having the beak of the female longer

than the body are far less numerous, and will probably not be

materially increased by future collecting.

In determining the systematic position of the tribe Balaninini,

more weight should be given to ungual structure than to that of

the meso-parapleure, for, as I have elsewhere pointed out, the

oblique truncature of the humeri although the most constant and

characteristic peculiarity of the Barini, is not confined by any

means to that tribe but may appear in a more or less marked

form in several other sections of the Curculionide, but, aside

from this, in point of fact the obliquity of humeral truncature in

the Balaninini is barely discernible, and is not at all comparable

with the conformation of these parts in the Barini. In the latter

tribe one of the most significant general characters is the sim-

plicity of the tarsal claws; in the Anthonomini on the other hand,

the toothed modifications are one of the most characteristic fea-

tures, simplicity being the notable exception. In Balaninus the

claws are conspicuously toothed internally, and this, in conjunc-

tion with the general habitus of the body, would seem to deter-

mine its closer relationship with the Anthonomini.

The following table includes only those species in which the

beak of the female is distinctly shorter than the body, and is con-

nected with the preceding section, containing those with the beak

of the female longer than the body, by naszcus, the latter bearing

a striking superficial resemblance to confusor, which is placed at

tne head of the table :—

the body, that of the male much shorter.

These short-beaked species probably feed upon nuts having thin

and exposed shells, such as acorns, and this circumstance, if true,

will account for their greater variety and numbers, the oaks being

numerous in species and having widely varying characteristics,

which must exert more or less influence in evolving what we

designate species among the depredating insects. The new spe-

cies are described below in order.

nearly uniform, pale ochreous in color, the scales on the pronotum slender

and directed transversely. Head scarcely more than % as wide as the pro-

thorax, the eyes separated by nearly °4 of their own width, the intermediate

surface with a small rounded puncture; beak equal in length to the elytra,

moderately slender, evenly and distinctly arcuate throughout the length,

punctate and feebly carinate above toward base, the antenne inserted just be-

the abdomen being strongly impressed toward the middle of the

two basal segments; the fifth segment is narrowly and feebly

sinuate at tip, with the surface feebly impressed, subtumid at each

side near the apex. The facies of the body is quite different from

that of any other species, owing to the short rhomboidal form,

prominent humeri and distinctly tubulate apex of the prothorax.

A single specimen, probably from the extreme southern part of

the State. :

B. nanulus.— Rather short and stout, subrhomboidal, piceous-black, the

legs rufescent; beak and antennz pale rufous; integument densely clothed

with an almost uniform mixture of white and brown scales, the latter longer

and more slender; white scales of the strial punctures generally shorter and

broader. Head nearly 144 as wideas the prothorax, the eyes separated by but

little more than 14 their own width, theinterval feebly sulcatulate; beak slen-

der, almost evenly arcuate, about as long as the elytra; antenne slender, in-

serted at about the middle, the first four joints of the funicle uniformly and

rather rapidly decreasing in length, the club elongate, fusiform and very

densely pubescent. Prothorax relatively small, fully 144 wider than long, the

sides parallel and nearly straight in basal 35, then moderately convergent and

subrectilinear to the truncate apex; disk densely punctured, the slender scales

close-set and arranged transversely, meeting along a fineand rather prominent

median line. Llytra but slightly longer than wide, more than twice as long

as the prothorax and fully 7% wider, the humeri moderately exposed and sub-

prominent; sides feebly convergent to near apical third, then much more

rapidly and more arcuate to the tip; strie moderately coarse and deep, rather

coarsely punctate, the intervals nearly flat and subrugose. Legs rather short,

the femora quite feebly inflated. Length 4.8 mm.; width 2.3 mm.

New Mexico (Las Vegas).

The single representative is a male, having the abdomen dis-

tinctly impressed in the middle toward base, the fifth only

slightly flattened, with the vestiture becoming finer, more hair-

like and suberect toward the middle and tip, and with the apex

transversely truncate, the pygidium clothed densely with long

erect brown and white hairs,the former the longer. This species

seems to be quite isolated and not closely related to any other.

B. occidentis.—Elongate-suboval, strongly convex, dark in color, with

dark rufous beak and antennze and very densely clothed throughout with

ochreous-yellow scales, only very slightly and unevenly variegated with some-

what darker brownish, the scales all long and very narrow, arranged trans-

versely and hair-like on the pronotum, where they generally become whitish

sublaterally toward base, paler, very broad, extremely dense and more closely

decumbent beneath. Head 44 as wide as the prothorax, the eyes separated by

but little more than 14 of their own width, the intervening surface scarcely

impressed; beak moderately slender, shorter than the elytra, nearly straight,

becoming arcuate distally, the antennz inserted slightly beyond the middle,

the funicle unusually stout and setose, with the first four joints decreas-

ing rather rapidly in length, the club fusiform and densely pubescent, with

the first joint narrowed and glabrous at base. Prothorax moderate in size,

densely punctate, 7 wider than long, the sides moderately convergent and

broadly, almost evenly arcuate from base to apex, rather straighter and more

convergent near the latter; apex transversely truncate. Elytra about 14 longer

than wide, distinctly more than twice as long as the prothorax and fully %

wider, the outline narrowly and almost evenly ogival from base to apex, the

humeri only moderately exposed and subprominent; striz somewhat fine,

punctured, the intervals broad and nearly flat, subrugose and concealed by the

vestiture. Legs moderate in length and in degree of femoral dilatation.

Length 5.9-6.6 mm. ; width 2.8-3.1 mm.

California (Sta. Cruz, Sonoma and Siskiyou Cos.).

This species is somewhat allied to the eastern uniformis, but

differs in its smaller size, shorter form, very dense covering of

slender ochreous scales, shorter and less slender male antennal

funicle, with the scape in the female fully as long as the next

three joints combined, narrower and more acuminate fifth ventral

of the male, and in its entire habitus. The description is drawn

from the male, that sex having the abdomen distinctiy impressed

medially at the base and the fifth segment very feebly impressed

and less pubescent toward the middle, with the apex concealed by

the long dense fulvous vestiture, the pygidium bristling with

long dense hairs as usual. The female is larger, nearly identical

in form but with a slightly larger prothorax, the beak ? as long

as the body, the antenne inserted between basal third and fourth,

with the funicle longer and more slender and the club smaller and

shorter, and the fifth ventral parabolic and feebly impressed, be-

ing also less pubescent at the middle. The vestiture along the

elytral suture is more prominent, dense and suberect except to-

ward base.

B. undulatus.—Stout, only moderately convex above, elongate-sub-

oval, dark in color; beak and antenne rufous, the former piceous toward base;

vestiture dense, the scales long and slender, pale ochreous in color, variegated

on the elytra with well-defined but broken wavy bands of darker brown.

Head distinctly less than 44 as wide as the prothorax, the eyes separated by 2

of their own width; beak moderately slender, almost evenly and rather

strongly arcuate, not quite as long as the elytra, the antenne inserted dis-

tinctly behind the middle; funicle slender, with the first four joints decreasing

rapidly in length, the club elongate-fusiform, densely pubescent, equal in

length to the first funicular joint, with the apices of the joints distinctly ex-

posed at the edges. Prothorax well developed, % wider than long, the sides

very feebly convergent and slightly arcuate to apical third, then more

rounded, convergent and subsinuate to the apex, which is feebly and angu-

larly sinuate and but little more than 14 as wide as the base; surface densely

punctate. Llytra but little longer than wide, only slightly more than twice

as long as the prothorax and about %¢ wider, subogival in form, the humeri

moderately prominent and exposed; striz rather coarse, strongly punctured,

the intervals nearly flat, moderately broad, rugose.. Entire under surface very

densely clothed with broader, more decumbent whitish scales. Legs moderate

in length and femoral dilatation. Length 6.5 mm.; width 3.4 mm.

Arizona.

The type isa male, having the usual large feeble indentation

at the base of the abdomen, the fifth segment toward tip and the

pygidium bristling with long dense pale hairs, the former promi-

nent at each side near the tip, with the apex concealed but prob-

ably truncate. This species may be distinguished from occidentis

by the more elongate beak, with more posteriorly inserted an-

tenne and larger prothorax of the male.

B. strictus.—Narrow and elongate-subrhomboidal, rather convex, dark

in color, the legs, beak and antennz rufous; vestiture dense, the scales long

and very slender, pale brown in color, paler toward the flanks of the prothorax;

in large irregularly subtransverse elytral areas and on the under surface, where

they become broader and more decumbent as usual. Head rather more than

1g as wide as the prothorax, the eyes separated by % of their own width, with

the interval not distinctly impressed; beak slender, feebly arcuate, rather more

so toward tip, % to % as long as the body, the antenne inserted a little be-

hind basal third, the scape rather longer than the first three joints of the funi-

cle, which decrease rapidly in length as usual, the club elongate, fusiform and

densely pubescent. Prothorax relatively small, nearly 44 wider than long,

widest at the middle, where the sides are rounded, thence very feebly conver-

gent and slightly arcuate to the base, and much more rapidly convergent and

feebly sinuate to the apex, the latter transversely truncate and % as wide as

the base; surface densely punctate. Elytra 14 longer than wide, 2% times as

long as the prothorax and very nearly 144 wider, elongate-ogival in form, the

humeri moderately exposed and rather prominent; strizs deep and punctured,

the intervals flat, rugose and moderately wide. Legs moderate in length and

femoral dilatation, the femoral tooth very large and conspicuous. Length

5.8-6.7 mm.; width 2.5-3.0 mm. .

New Mexico (Las Vegas).

The types before me are females and I have not seen the .

male; the species can be distinguished at once from any of those

allied to untformis by the very large femoral tooth, as described

in the table, as well as by the peculiar form of the prothorax.

The female has a small and very feeble median indentation at the

middle of the fifth ventral. | :

Two specimens labeled “‘ New Jersey,” both males, are placed

Coleopterological Notices, VII. 661

with this species for the present; they are evidently shorter and

stouter in general form, with the beak about as long as the elytra,

but agree in the peculiar ornamentation of the elytra, form of the

prothorax and dentition of the femora.

B. longipes.—Moderately stout, thick and elongate-subrhomboidal,

rufo-testaceous in color, the beak and antenne still paler rufous; vestiture ex-

tremely dense, consisting of long, slender and pale brownish-ochreous scales,

feebly interspersed with slightly paler spots on the elytra and also paler toward

the sides of the prothorax, more whitish, broader and dense on the under sur-

face. Head nearly 44 as wide as the prothorax, the eyes separated by nearly 34

of their own width, the interval broadly and feebly concave; beak 4¢ as long

as the body, very slender, rather arcuate, more strongly beyond the middle; an-

tenn inserted somewhat behind basal third, slender, the funicle long, with

the first four joints decreasing in length, the club fusiform, densely pubescent

and as long as the two preceding joints combined. Prothorax well developed,

26 wider than long, the sides rather more rounded just before the middle, thence

very feebly divergent and slightly arcuate to the base and more strongly con-

vergent and just visibly sinuate to the apex, which is truncate, becoming feebly

sinuate at the middle; disk densely punctate. Llytra scarcely 4 longer than

wide, nearly 244 times as long as the prothorax and a little less than 14 wider;

humeri rather widely exposed and prominent, the sides thence rather strongly

convergent and nearly straight, rapidly subparabolic at tip, with the posterior

discal swelling somewhat noticeable; striz moderate, rather closely punctate, _

the intervals wide; sutural vestiture rather prominent posteriorly. Legs un-

usually long, the femora moderately dilated, with the tooth very large, its ver-

tical distal edge much longer than the femoral width in continuation of it.

Length 6.5-7.0 mm.; width 3.2-3.6 mm.

Colorado (Manitou).

The description is from a female example, the fifth ventral in

that sex having a small median concavity which is much less

densely clothed. The male is a little smaller but does not differ

greatly in form, having the beak distinctly shorter than the elytra,

with the antenne inserted at the middle, the club a little larger

and more elongate, the abdomen broadly and feebly impressed at

base, and the truncate fifth segment toward the sides and the en-

tire pygidium bristling with long erect hairs.

This species very closely resembles the Californian occideniis,

but differs in the more prominent femoral teeth, longer legs and

beak, more rhomboidal and less oval form, more prominent humeri

and several other features. ae

B. sulcatulus.—Narrowly elongate-oval and strongly convex, dark

piceous in color, the legs rufescent, the beak and antenne rufous ; vestiture

white, variegated with indefinite subtransverse patches on the elytra, in which

662 : Coleopterological Notices, VII.

the scales become slightly less slender and very dense ; scales of the pronotum

linear and sparse, becoming wider and denser toward the sides, broad and dense

on the under surface. Head fully 14 as wide as the prothorax, the eyes sepa-

rated by slightly more than 14 of their own width, the intermediate surface

not foveate ; beak slender, straight, becoming gradually feebly arcuate distally,

very nearly as long as the elytra and nearly % as long as the body, the an-

tennee inserted at basal third, the scape short, not as long as the first three

joints of the funicle, the latter decreasing rapidly in length. Prothorax mod-

erately developed, scarcely “g wider than long, the sides subparallel, evenly

and rather strongly arcuate, becoming more rapidly convergent and then sin-

uate anteriorly, the apex subtubulate and transversely rectilinear ; surface

rather coarsely, densely punctate. lytra more elongate than usual in this sec-

tion of the genus, 4g longer than wide, 2g wider than the prothorax, evenly

elongate-ogival in form, acute behind, the subapical prominences almost obso-

lete ; suture slightly prominent toward tip; humeri narrowly exposed and

rounded ; striz: coarse, deep and punctate, 14 as wide as the intervals, the lat-

ter flat and rugose. Legs rather short, the femora only feebly inflated. Length

5.2 mm.; width 2.4mm.

New Mexico (Las Vegas).

This small species is allied structurally to uniformis by the in-

sertion of the antenne, but is placed in the present subsection

because of the very short beak ; it is however quite isolated and

distinct. The fifth ventral of the female, which is the only sex

known to me, is broadly parabolic, and is scarcely visibly im-

pressed and not differently clothed toward the middle. In the

female of untformis the abdomen is clothed with narrower scales

toward tip and the fifth segment is deeply indented, the size, also,

being much larger; in addition to this the beak is as long as the

elytra, and the elytral intervals four or five times as wide as the

striee.

B. brevirostris.—Stout, strongly convex and subrhomboidal, blackish

in color, the legs rufescent; beak and antenne rufous; vestiture consisting of

long slender scales, dense and concealing the integuments, pale luteous-brown

in color, with but feeble vestiges of variegation on the elytra. Head not quite

1g as wide as the prothorax, the eyes separated by fully % of their own width,

the interval flat, densely punctured but not medially foveate; beak very short,

scarcely more than 14 as long as the body, somewhat stout, straight, becoming

feebly arcuate toward tip, distinctly punctured toward base, the antenneze in-

serted near basal %, the funicle rather slender, with the three basal joints de-

creasing rather rapidly in length, the club well developed. Prothoraz relatively

rather large, % wider than long, the sides broadly and almost evenly arcuate

and feebly convergent from the base almost to the apex, where they become feebly

sinuate; apex feebly, subangularly emarginate; surface densely punctate, the

punctures largely coalescent sublongitudinally. Elytra slightly longer than

Coleopterological Notices, VII. 663

wide, subtriangular with feebly arcuate sides, the subapical swellings distinct;

humeri rounded, very moderately exposed and scarcely prominent; stris: mod-

erately fine, punctured. Legs rather short, the femoral enlargement moder-

ately strong, the teeth rather well developed but with the distal slope oblique.

Length 6.3-6.5 mm.; width 3.2 mm.

New Mexico (Las Vegas).

The type described above is a female, in order to better com-

pare the species with those closely related. The male is a little

shorter, with the prothorax relatively smaller, and the humeri

more exposed and prominent; the beak is scarcely shorter than

in the female, 4.as long as the body, more strongly and evenly

arcuate, more punctured and carinate above toward base and

with the antenne inserted at apical 2; the abdomen is broadly

impressed at base toward the middle, and the fifth segment is

sinuato-truncate at tip.

This species is evidently allied to obtusus, but differs in its

smaller size, less obese form, relatively larger prothorax of the

female, narrower and less broadly oval dense scutellar cluster of

squamules, less variegated vestiture and in numerous other

characters. |

B. monticola.—Elongate-suboval, strongly convex, black, the legs feebly

rufescent ; beak and antenne rufo-piceous; vestiture dense, consisting of rather

broad whitish scales, variegated with browner patches on the elytra, a

transverse band of whitish near apical third more conspicuous, the scales nar-

rower and brownish on the pronotum, where they are arranged transversely as

usual, broader and paler beneath. Head 14 as wide as the prothorax, the eyes

separated by % of their own width, without distinct intermediate puncture,

the beak scarcely more than 14 as long as the elytra, moderately stout, arcuate

distally, the antennze inserted slightly behind the middle, the scape nearly as

long as the first four joints of the funicle, the latter decreasing in length ; club

moderate in.size, rather stout. Prothorax well developed, scarcely 74 wider

than long, the sides subparallel and broadly arcuate to near apical third, then

more rapidly rounded and convergent, becoming sinuate near the apex, the

latter subtubulate, truncate, feebly sinuate at the middle; surface densely

punctate. Elytra not 4 longer than wide, rather more than % wider than the

prothorax, subogival in form, the subapical prominences moderate ; humeri

moderately exposed and rounded. Legs and femoral dilatation moderate.

Length 6.5 mm.; width 3.2 mm.

Colorado (Colorado Springs). Mr. Wickham.

The only specimen known to me isa female, the fifth ventral

tion toward tip. This species is allied somewhat to obtusus and

brevirostris, but differs from the former more especially in its

much less obese form, and from the latter in its much more

variegated vestiture; from both it differs in its rather more sub-

tubulate apex of the prothorax and in the indentation of the fifth

ventral segment of the female.

TYCHIINI.

TYCHIUS Schonh.

The minute species constituting subgenus IV, as previously

defined by me, are becoming known in considerable number ; they

inhabit the dry and barren regions of the southwestern United

States. The three following are to be added to those previously

defined (Col. Not. IV, p. 420):

T. Sulcatulus n. sp.—Oblong-oval, moderately convex above, black, the

legs feebly picescent, the beak feebly rufo-piceous toward tip; body densely

clothed with a crust of large, rounded and concave scales, which are wanting

in certain areas on the elytra, especially on intervals two to four, where they |

are replaced by narrower and rather brownish scales, a small transverse median

spot of large scales behind the middle, involving the second interval, excepted ;

scales sometimes becoming brownish also at each side of the middle line of

the pronotum, more broadly toward base, the elytral intervals also with dis-

tant scales which are suberect. Head and beak densely incrusted with whitish

scales, glabrous but still somewhat rugose toward tip, rather strongly tapering

throughout, the antenne inserted at or beyond the middle. Prothorax twice

as wide as the head, 14 to 7g wider than long, the sides moderately convergent

and arcuate from base to apex, feebly sinuate behind the latter, which is trun-

cate and fully % as wide as the base; punctures concealed, dense. lytra

rather short, about 1g longer than wide, 214 times as long as the prothorax and

1g wider, the sides parallel and nearly straight, broadly rounded behind;

humeri distinctly exposed and rounded; strize very coarse, deep and sulciform,

strongly punctured, the intervals feebly rugose, alternately narrow and much

wider. Legs short and stout, densely squamose, the scales of the femora large

and rounded. Length 1.5-1.7 mm.; width 0.65-0.75 mm.

Texas (Brownsville—Pt. Isabel). Mr. Wickham.

A small maritime species, remarkable in having the elytral

strize coarse and deep and alternating in distance asunder. The

sexual differences do not seem to be very marked in the large

series in my cabinet. It may be placed near simplex.

T. inermis n. sp.—Oval, strongly convex, piceous-black, the integu-

ments densely clothed with long slender decumbent scales, whitish in color

but variegated with large confused areas of darker brown, whitish toward the

sides and along the median line of the pronotum, larger, broadly oval and

nearly white beneath, without trace of erect scales or setze. Head and basal

parts of the beak densely squamose; beak stout toward base, the portion be-

yond the antennz rapidly narrower, polished and glabrous, as long as the head

and prothorax, a little shorter and stouter in the male, the antennz inserted

at the middle in the femaie and at apical % in the male, the first funicular

joint longer than the next two combined, especially in the male, and much

stouter. Prothorax more than % wider than long, 244 times as wide as the

head, the sides strongly convergent, strongly and almost evenly arcuate from

base to apex, minutely sinuate just behind the latter; punctures not wholly

concealed, circular, moderate in size, nearly in mutual contact but not

crowded. lytra neatly 244 times as long as the prothorax and about % wider,

%, longer than wide, the sides parallel and feebly arcuate; apex broadly ob-

tuse; humeri slightly exposed and oblique; strive rather fine, strongly punc-

tate, the intervals feebly convex, slightly rugose, with the scales disposed

closely and irregularly. Legs rather short and stout. Length 1.7-2.0 mm.;

width 0.8-0.9 mm.

Texas (Brownsville). Mr. Wickham.

This species is to be placed near mica, but is slightly larger

and more elongate, with narrower squamules, and differs besides

‘in the larger first funicular joint of the male. It is represented

before me by a large series.

T. transversus n. sp.—Oblong, strongly convex, blackish, the legs and

beak rufous; body clothed throughout with a very dense crust of large, broadly

rounded, non-strigose and overlapping scales, which conceal the integuments,

the scales whitish and of various shades of brown, the white scales more evi-

dent toward the sides and mid-basal regions of the pronotum, in a large sutural

_ spot before the middle of the elytra and in an almost entire straight trans-

verse band near apical third, the elytral striz evident merely as fine lines sepa-

rating the single or partially double lines of scales, the intervals bearing

single series of widely separated and very long, erect bristles, which are stri-

gose and uniformly tapering from base to their acute apices. Head and beak

clothed with the dense indument of scales, with erect sparse spinules irregu-

larly disposed; beak short, very rapidly tapering, not longer than the pro-

thorax, the antenne inserted at the middle, the portion beyond the antenne

glabrous and shining. Prothorax nearly as long as wide, thesides parallel and

nearly straight to near apical fourth, then rounded and converging for a short

distance to the broadly tubulate apex, the latter broad, truncate, 74 as wide as

the base; sculpture entirely concealed, the bristles sparse, much shorter than

those of the elytra. Elytra rather short, scarcely 14 longer than wide, more

than twice as long as the prothorax and % wider; sides parallel and nearly

straight; apex broadly and obtusely subangulate from above; humeri quite

widely exposed at base and rather narrowly rounded; surface entirely con-

cealed. Legs short, densely squamose. Length 1.3 mm.; width 0.6 mm.

SEIBINIA Germ.

The following species seems to be congeneric with fulva, but is

very much smaller and more narrowly oval, and has the scutellum

concealed, as in the European primita, which it considerably re-

sembles in outline.

§. ochreosa n. sp.—Oval, strongly convex, dark rufo-piceous. in color,

the beak and legs pale; integuments densely clothed above with moderately

elongate, closely decumbent, uniformly bright ochreous-yellow scales, the

scales denser and more prominent by superposition along the median parts of

the elytral intervals, but without isolated suberect squamules, the scales of

the under surface whitish and much broader, forming a dense crust. Head

and basal parts of the beak densely squamulose as usual, the beak distinctly

shorter than the head and prothorax in both sexes, differing but little sexually,

rapidly tapering, polished and glabrous beyond the antenne, the latter in-

serted at the middle in the female and just beyond that point in the male,

short and stout in both, the scape relatively shorter and the club smaller in

the female. Prothorax about 244 times as wide as the head, 4 to 3% wider

than long, the sides strongly convergent and almost evenly arcuate from base

to the feeble apical sinuation; apex rather less than % as wide as the base;

punctures concealed, moderate in size and depth and polygonally crowded.

Elytra rather short, oval, less than 244 times as long as the prothorax and not

more than % wider; sides parallel, distinctly and evenly arcuate, the apex

broadly obtuse, the apices individually rounded; humeri obliquely rounded

and not exposed at base;-stris moderate in width, shallow, with deep and

somewhat widely separated punctures, each of which bears a long slender and

decumbent hair-like squamule. Legs short and stout, rather densely squamu-

lose. Length 1.4-1.6 mm.; width 0.65-0.75 mm.

ZYGOPINI.

The generic characters of this tribe were only superficially

outlined by LeConte in the “ Rhynchophora of America North

of Mexico,” and Zygops had not been discovered within our

territories at that time. Psomus, allied to Acoptus, has also

been added recently. Another statement of the genera occurring

Coleopterological Notices, VII. 667

in the United States would therefore seem to be desirable. It is

quite evident that none of our genera, except Zygops, can be

held to be identical with the tropical groups defined by Schon-

herr; I have therefore regarded them as different in the follow-

ing table and have assigned new names to the Piazurus and Cop-

turus of LeConte :—

Pygidium large, vertical and exposed, the axial line of the abdomen nearly

straight; mesosternum vertical, the side-pieces not obliquely truncating the

_ The few species assigned to Piazurus by LeConte do not be-

long to the Piazurides of Lacordaire at all, but to the Lechri-

opides, the mesosternal canal being closed behind and not open

in the form of a gutter, as it is in the much larger and broadly

~rhomboidal Piazurus; that genus differs moreover in its elongate

third joint of the antennal funicle and very strongly toothed

femora. The genus Gelus, which I have proposed above for

oculatus and californicus, is very closely allied to Lechriops, as

shown by a Brazilian representative of the latter before me, but .

differs in having the abdominal sutures two to four strongly re- _

flexed at the sides, only the second being affected in Lechriops

in its much shorter and stouter legs and in its non-contiguous

eyes. The Piazurus subfasciatus of LeConte, should be reéxam-

ined with a view to determining more fully its generic affinities ;

it may possibly prove to be non-associable with oculatus, and is

not represented in my cabinet at present.

The multitudinous small and minute Brazilian species will form

numerous genera, and the eleven now before me seem to show

that it will be impossible to maintain the groups laid down by

Lacordaire. There are several distinct genera at present confused

under the name Copturus, intimated indeed by that author.

GYROTUS n. gen.

The single representative of this genus differs considerably in

facies from those of Copturodes, because of the coarse punctures

of the elytral strie, widely separated eyes and acutely prominent

post-ocular processes of the prothorax; it may be described as

follows :—

G. munitus n. sp.—Cylindric-oval, convex and moderately stout, black

throughout, the tibis, beak and antenne rufescent; body clothed throughout

with a dense crust of large, rounded and non-strigose scales, whitish toward the

sides of the prothorax, more narrowly toward base, on the entire under surface

and in a few widely scattered, somewhat elevated or thickened clusters on the

elytra, also in a large spot at the middle of the elytral flanks; elsewhere dark

grayish in color. Head well developed, the eyes finely faceted, rather large,

separated on the front above by their own width and by much more below, the

inner margins feebly arcuate and strongly divergent downward throughout, the

interocular surface with a large deep central fovea; beak stout, squamose at

base, glabrous and coarsely punctato-rugose thence to the apex, the latter mod-

erately dilated; antennz moderately slender, inserted behind the middle, the

four basal joints of the funicle decreasing uniformly and rather rapidly in

Coleopterological Notices, VII. 669

length, the club much longer than the four preceding joints combined, elongate-

oval, with its three joints decreasing slowly and regularly in length. Pro-

thorax about as long as wide, the sides parallel and nearly straight, with

a broadly rounded and slightly prominent swelling near-apical third, the sides -

thence deeply sinuate and oblique to the broadly subtubulate and sinuato-

truncate apex; the flanks produced obliquely outward at apex in an acute corne-

ous process behind the lower part of the eyes; sculpture concealed, but

coarsely and densely punctate, the darker scales deeply concave. Scutellum

small. Elytra scarcely more than 4g longer than wide, 14 longer than the pro-

thorax and only very slightly wider; humeri not prominent; apex as in Cop-

turodes; strize consisting of series of very large, rounded and almost contigu-

ous but scarcely united punctures. Abdomen rapidly ascending at tip, the first.

two segments very large as in Copturodes, the third with a small feeble cus-

piform median tooth. Legs nearly as in Copturodes, densely squamose.

Length 4.0 mm.; width 1.6 mm.

Southern California.

The séx of the single specimen before me cannot be deter-

mined at present.

COPTURODES n. gen.

This genus differs from Copturus in its less rhombiform body,

less unequal first and second funicular joints and completely un-

armed femora. The species are numerous within the United

States and possibly extend somewhat into Mexico, but probably

not much further to the southward; those known to me may be

thus distinguished among themselves :—

Body rather stout, the elytra distinctly less than 14 longer than wide......... 2

Body elongate and more narrowly subcylindric-oval, the elytra 144 longer than

wide or more, always very densely clothed with scales which are usually

In this table the characters relating to the eyes of longulus are

assumed, as no mention of their form is made in the original

description. As far as I have been able to discover, the general

form and mutual separation of the eyes are affected but slightly

by the sex of the individual, and this seems to be the case also in

all the tropical species which I have studied.

Minutus Lec. is not included in the table, as it must form a

distinct genus because of the structure of the scales which clothe

the body, and on account of peculiarities of antennal structure.

Mammillatus is the largest and finest species of the genus, readily

recognizable by its stout form and the large subquadrate blotch

of white scales at each side of the base of the pronotum. The

new species of the table are described below in order.

C. cockerelli.— Densely clothed throughout with large decumbent scales

of a uniform pale ochreous-yellow color, becoming largely white at the sides

of the prothorax, and broadly along the elytral suture, with two transverse

series of indefinite white blotches curving forward externally, the anterior at-

taining the humerus; under surface and legs clothed throughout with large

white scales. Head and basal parts of the beak densely clothed with white

scales; inner margins of the eyes strongly, evenly arcuate, the eyes most ap-

proximate at about the middle of the front and there separated by % of their own

width; beak coarsely but not densely punctured; antennal club well developed,

oval, pointed, about as long as the four last joints of the funicle, minutely

pubescent, with its first joint constituting about % of the mass. Prothorax

slightly shorter than wide, rather abruptly narrowed and broadly subtubulate

at apex, the sidesfeebly bisinuate; sculpture entirely concealed. Elytra rather

more than % longer than wide, but little wider than the prothorax and %

longer; strize concealed but marked by a series of conspicuous narrow pointed

scales lying in the level of the general crust. Length 3.4 mm.; width 1.4 mm.

New Mexico (Las Cruces).

672 Coleopterological Notices, VII.

A single specimen was kindly communicated by Mr. T. D. A.

Cockerell, in whose name it gives me pleasure to dedicate a dis-

tinct and interesting addition to the genus.

Cc. suturalis.—Suboval, densely clothed throughout above with large

pale brown scales, becoming white in a fine median line and broader vitta at

each side of the pronotum, broadly along the elytral suture, more narrowly or

obsoletely toward base and sparsely and irregularly in an oblique region ex-

tending from the humeri to the suture near apical third; under surface and

legs densely clothed with white scales, feebly intermingled with pale brown.

Head and basal parts of the beak densely clothed with white scales, the eyes

well separated, the point of minimum distance asunder being at. or somewhat

below the middle of the front, where they are separated by about 1% of their

own width. Prothorax slightly shorter than wide, the sides subparallel and

biarcuate, abruptly rounded and convergent anteriorly to the broadly subtubu-

late apex; sculpture entirely concealed, the scales much smaller and less elon-

gate than in cockerelli. Elytra nearly as in cockerelli and adspersus, but more

distinctly sinuate at the sides near basal third than in the former. Length

2.5-2.8 mm.; width 1.0-1.2 mm.

Utah south wettenn = Me Weidt); Arizona.

A rather small species allied to cockerelli, but differing in Ne

conformation of the eyes, these being more widely separated and

with the inner margins more abruptly and widely diverging in-

feriorly, and with their upper angle much less obtuse. In ad-

spersus the eyes are nearly as in cockerellt but somewhat more

narrowly separated and with their inner margins still more

strongly arcuate. Of adspersus I have before me a very large

series taken at Austin, Texas; it also occurs in Colorado and

Arizona. ‘

C. koebelei.—Stout, oblong-oval, moderately convex above and clothed

densely with large dark brown scales, becoming white at the sides of the pro-

thorax and in two transverse arcuate series of small spots on the elytra; scales

dense and almost uniformly white on the under surface. Head deeply exca-

vated above between the eyes, the latter separated by about % of their own

width, with the point of minimum distance asunder rather below the middle;

beak somewhat rugosely sculptured. Prothorax not quite as long as wide,

somewhat abruptly: narrowed and rounded anteriorly to the broadly sub-

tubulate apex; sides parallel and feebly bisinuate; surface very densely and

rather coarsely cribrate. Elytra % longer than wide, 1g wider than the pro-

thorax and *¢ longer; strize rather coarse and strongly punctured, not entirely

concealed by the vestiture, the squamules of the strial punctures rather slender.

tion, the scales being largely denuded throughout the body and

legs, but, from the small patches remaining, it is certain that well

preserved specimens will prove to be densely squamose through-

out. | i :

C. missourianus.—Stout, elongate-suboval, black, the scales separated

except in the condensed areas, the latter having the scales pale in color, espec-

ially evident broadly along the elytral suture and unevenly toward base, also

in some small areas subtransversely arranged behind the middle, the scales

elsewhere on the elytra small, oval, dark in color and widely separated, the

scales of the pronotum large and rounded, each filling one of the coarse, deep

and slightly separated punctures. Head, basal parts of the beak, entire under

surface and legs densely clothed with whitish scales; beak finely, sparsely

punctured and glabrous beyond the point of antennal insertion; second joint

of the funicle longer than the next two combined. Prothorax subconical, not

quite as long as wide, the sides feebly convergent and nearly straight almost to |

the apex, then a little more rounded and convergent to the apex, which is broad-

ly sinuato-truncate and notat all tubulate; surface within the densely squamose

flanks coarsely and not very densely punctured, with a short impunctate

median line. lytra short and broad, 14 longer than wide, °4 longer than the

prothorax and % wider, the humeri rather prominent; sides rapidly convergent

and rounded behind to the apical prolongation; striz rather coarse, the sqguam-

ules slender, broader in the areas of condensation. Length 3.8 mm.; width

Missouri (St Louis). Mr. Soltau.

This species, described above from the female, is about as large

as operculatus and greatly resembles it, but is stouter, with the

prothorax more sparsely punctured and more conical, the sides

being less arcuate. The squamulation of the elytra is still more

‘uneven. Of operculatus I have specimens before me from Dakota,

Kansas and Iowa.

C. sparsus.—Stout, oval, rather strongly convex, the body and legs deep

black throughout; scales pure white, oval, rather sparse except ina sublateral

pronotal vitta and in some small nubilate condensed spots disposed in the

usual two posteriorly arcuate series on the elytra; scales of the pronotum

moderately large, broadly rounded, each filling one of the large separated

punctures, those of the under surface not quite contiguous. Head and basal

parts of the beak rather’densely squamose, the eyes separated at lower third by

about 14 of their own width; beak finely punctulate, black, polished and

glabrous beyond the point of antennal insertion. Prothorax %, wider than

jong, the sides subparallel, distinctly but somewhat unevenly arcuate, oblique

and feebly sinuate at the apex, the latter broadly sinuate and not at all tubu-

late; punctures coarse and deep. Eilytra short, 1g longer than wide, nearly

twice as long as the prothorax and 1¢ wider, the sides quite arcuate; humeri

not at all exposed at base, the humeral callus moderately prominent; pos-

- Allied to operculatus but smaller and relatively more obese,

with the punctures and scales sparser, the prothorax much

shorter and the eyes more narrowly separated. The scales of the

elytra are more conspicuous along the narrower intervals toward

base. The type is probably a male.

C. floridanus.—Only very moderately stout, elongate-oval and convex,

deep black throughont, the tibiz and tarsi rufescent; scales relatively large,

white, dense in the condensed areas, pale brownish elsewhere, largely brownish

at each side of the median line of the pronotum; white condensations of the

elytra linear and very indistinct, the arrangement scarcely discernible but con-

forming to the general type prevailing in the genus. Head and basal parts of

the beak densely albido-squamose, the eyes at lower third separated by but

little more than ]{ of their own width. Prothorax not quite as long as wide,

rather wider at apical third than at base, the sides feebly biarcuate, more con-

vergent and sinuate at the apex, which is feebly sinuato-truncate and scarcely

subtubulate; punctures only moderately coarse and distinctly dense. Elytra

Florida (Haw Creek). Hubbard and Schwarz.

A small species, unusually narrow for this section of the genus

and allied to nanulus, but differing in the extremely confused

ornamentation, smaller size and narrower form. ‘Two specimens.

Of nanulus, I have before me a large series from Iowa, Ohio,

Kentucky, North Carolina and Maryland; it varies much in the

distinctness of the pale markings of the elytra, and, as usual, these

seem to be more sharply defined in the females than in the males.

The prothorax varies much in length and strength of the lateral

biarcuation, and it is possible that I may confound some distinct

species together, but the subject is too difficult to pronounce

upon in the absence of full and carefully collected series.

C. frontalis.—Stout, suboval, moderately convex, deep black through-

out, the entire under surface and sides of the prothorax densely clothed with

large white scales, the flanks of the prothorax anteriorly more sparsely and

irregularly so; white scales also evident on the median line of the pronotum

toward base, and, on the elytra, toward base and scutellum, in a short line on

the second interval behind the middle with an oblique posterior offset com-

posed of short lines on the third and fourth intervals, and in a few obscure

discal spots elsewhere ; the scales of the elytra are rather large but separated,

deep brown in tint and inconspicuous, those of the pronotum large, rounded

and brown, each filling one of the coarse punctures. Head and basal parts of

the beak clothed with white scales, except the deep frontal depression between

the diverging upper parts of the eyes, which is clothed with slender brown

scales ; eyes separated at lower third by fully 14 of their own width. Prothorax

slightly shorter than wide, the sides subparallel, broadly sinuate at the middle

and slightly narrowed at base, oblique and sinuate at apex, the latter broad

and very feebly sinuate ; punctures coarse, deep and contiguous. Elytra fully

Allied to quercus, but differing in its less ee ee and in pe-

culiarities of ornamentation mentioned in the table, also in the

much larger and more rounded scales of the pronotum. Of quer-

cus | have specimens from Illinois, Indiana and District of Co-

lumbia.

C. cavifrons.—Stout, suboval, convex, deep black throughout, densely

clothed beneath and on the flanks of the prothorax, except anteriorly, with

large white scales, also on the median line of the pronotum at base and apex,

in the sutural region of the elytra to just behind the middle, where the offset

forming part of the posterior transverse series is oblique ; externally, there are

isolated spots of white forming the two vague, posteriorly arcuate series pre-

vailing throughout the genus ; pronotum elsewhere clothed with slender dark

squamules, the ground of the elytra similarly clothed with dark scales which

are narrow, oval and inconspicuous ; lower parts and extreme upper point of

the front and base of the beak clothed with white scales, the deep excavation

apical umbones of the elytra. Three specimens.

, C. nubilatus.—Elongate, suboval, convex, the integument completely

concealed by a dense crust of nae large, widely overlapping scales,

which are in general dark coppery-brown in color above, becoming whitish in

irregular spots toward the sides and apex of the pronotum and especially at

base, also in the middle at base and dispersed in a rhombiform discal spot ; on

the elytra the pale scales are mingled with brown in a generally oblique area

embracing the base and extending to the suture at the middle, and in a less

oblique band behind the middle, which is interrupted at the suture ; under

ceous brown. Head and base of the beak densely clothed with whitish scales

speckled with brown, the eyes at lower third separated by less than 14 of their

sparsely clothed with short hairs as usual. Prothnnes nearly as long as wide,

widest and broadly rounded just behind the middle, the sides gradually con-

vergent and straight or very feebly bisinuate thence to the apex, which is

broadly sinuate ; sculpture completely concealed, the scales feebly convex,

‘broadly rounded in form, dark cupreous in color, but largely intermingled

with white beneath and on the legs, densely white also toward the base of the

‘pronotum sublaterally and at the middle, also feebly interspersed with white

This species is allied to nubilaius, but may be distinguished by

a somewhat different pattern of ely fal ornamentation, conforma-

tion of the front between the eyes, less obtuse upper angles of the

-eyes and other characters. The type is probably a male.

C. subcupreus.—Narrowly cylindric-oval, convex, covered throughout

with a dense crust of moderately large, widely overlapping, dark cupreous

scales becoming largely white beneath, at the base of the beak and toward the

base of the femora, with some scattered white scales on the head and pronotum

with a larger spot near each side of the base of the latter, also with a few

widely scattered spots of white scales on the elytra, the more distinct of which

are one just behind the humeral callus and two, placed obliquely, on each be-

hind the middle. Head moderate in size, the eyes separated at lower fourth

by scarcely 14 of their own width ; second funicular joint-as long as the next

overlapping scales, which are dark chocolate-brown above, with a slight

sprinkling of white on the pronotum and white near the sides toward base but

only very minutely at the middle of the base, also sparsely interspersed with

parts of the femora densely clothed with white scales, only sparsely inter-

mingled with isolated brown scales and solely toward the sides of the under

surface. Head and eyes well developed, the latter below the middle sep-

arated by scarcely 3¢ of their own width; beak and antenne black, the

second funicular joint shorter than the first but fully as long as the next two

combined. Prothorax not quite as long as wide, the sides subparallel and

broadly, somewhat unevenly arcuate, oblique and sinuate for a short distance

at apex, the latter broadly sinuato-truncate; surface completely concealed, the

scales very broadly and deeply concave. Llytra fully 14 longer than wide, 4%

longer than the prothorax and about 44 wider, the sides broadly arcuate; sub-

apical umbones small and feeble; strize concealed, the crust of scales broadly

convex on the intervals. Length 2.8 mm.; width 1.0 mm.

Colorado.

This species is evidently more allied to subcupreus than to the

Pacific coast species in the form of the antenne and general

facies; it is decidedly larger than subcupreus, and differs in the

ornamentation of the elytra. In both of them the triangular

glabrous space at the middle of the occiput is unusually large.

C. dispersus.—Cylindric-oval and convex, densely clothed with a crust

of moderately large overlapping scales, which are uniformly white beneath,

on the base of the beak and on the femora except above and toward apex of the

latter; scales of the upper surface dark chocolate-brown, interspersed with

isolated white scales toward the sides and median regions of the pronotum,

sometimes not especially more evidently so toward base, and, on the elytra, in

two transversely and posteriorly arcuate regions before and behind the middle

and also at apex. Head more largely clothed with white scales, the eyes large,

broad and well developed, separated at lower fourth of their extent by scarcely

4¢ of their own width, the inner margins thence widely and rapidly diverging

inferiorly and strongly arcuate. Prothorax distinctly shorter than wide, the

sides parallel and scarcely arcuate, becoming oblique and sinuate near the

apex; sculpture entirely concealed, the scales generally more or less impressed

along their median lines, especially toward their bases. Elytra rather more

than 144 longer than wide, twice as long as the prothorax and 14 wider, just

visibly arcuate at the sides; humeri rounded for a very short distance to the

prothorax, the prominence scarcely distinct; subapical umbones feeble; strize

concealed, the scaly crust but feebly convex along the intervals. Length

2.2-2.5 mm.; width 0.8-0.95 mm.

turodes in its subcontiguous eyes, very small and narrowly oval

antennal club, with less distinct annuli and still longer basal joint,

and in its somewhat shorter second joint of the antennal funicle,

which, in the male, is but little longer than the third, and in the

female a little shorter than the next two combined.* It also

differs in its elongate and distinctly strigose scales, these being

disposed sparsely along the strial intervals toward base, behind

the middle for a short distance, near the apex and along the

suture except at the middle, and also in its nearly simple elytral

apices behind the umbones. The type is Copturus minutus of

LeConte.

The table published by Dr. LeConte (Proc. Am. Phil. Soc.,

XV, p. 265) indicates groups defined by certain differences in the

elongate posterior legs; these groups are retained and increased

in number in the following table, which includes all the species

known to me at present :—

Hind femora armed beneath with several long slender and erect dentiform

spinules, the corresponding tibize broad, arcuate and with the external -

margin irregular; elytra with four tufts of denser pubescence arranged in

a very short broad trapezium.

- Integuments red, mottled with black; hind femora and basal parts of the

tibize in great part red; subsutural tufts of the elytra well defined.

The last two species of the table are unknown to me in

nature. The new species. defined in the table are described below

in order.

TT’. Spinipes.—Form as in lecontei, smaller, black throughout, except the

tip of the elytra, which is red; antenne and four anterior legs pale flavo-testa-

ceous; basal half of the hind femora above and distal extremity of the cor- |

. responding tarsi pale rufous; beak rufous at tip; upper surface thinly clothed

with gray-white, subdecumbent pubescence, which becomes moderately dense

toward the sides of the prothorax and in a transverse line expanded at the

suture across the middle of the elytra, the expanded part—corresponding with

the subsutural tufts of lecontei—being but slightly denser ; discal tufts minute

and situated behind the pubescent band; body beneath densely clothed with

white pubescence anteriorly, the abdomen very sparsely pubescent. Length

2.1 mm.; width 1.75 mm.

New Jersey. Mr. Julich.

Allied to lecontez, but much smaller and less pubescent above,

with the hind tibize much narrower, less bent and only feebly un-

dulated along the externaledge. As in lecontez, the white hairs of

the body and legs are very composite, consisting of three to

seven hairs split from a very short common foot-stalk.

T. sracilipes.—Form asin centralis, the surface shining, black, the elytral

suture narrowly and feebly, and a straight transverse band slightly broader

toward the suture and situated just before the middle, testaceous; antenne,

tip of beak and four anterior legs pale testaceous; hind legs deep black

throughout, the tarsi piceous; pubescence sparse, with a number of long erect

setze on the elytra and some longer whitish hairs on the suture toward tip, the

small central white tuft divided by the suture situated near basal fourth of

the elytral suture as usual; body sparsely pubescent beneath, except at the

sides anteriorly ; elytra with moderately impressed series of vary, coarse and

close-set punctures. Length 2.2 mm.; width 1.5 mm.

and with a series of long stiff erect sete, the extreme tip very

feebly everted. eat

T. rhombus.—-Form nearly as in centralis; body shining, black through-

out, the four anterior legs and antenne pale testaceous; hind legs black, ex-

cept basal 3¢ of the femora, which is rufous; hairs of the upper surface ochreous

in color, decumbent, numerous and strongly multifurcate, with numerous long

erect black bristles, a sutural series of white sets near the apex and a trans-

verse sutural white tufted spot before the middle of the elytra; hairs denser

and white also on the median line and flanks of the pronotum at base, on the

under surface rather dense and white throughout, except near the middle of the

abdomen toward base, the last segment bristing with sparse white sete; elytra

with feebly impressed series of coarse and deep punctures. Length 2.0 mm.;

width 1.6 mm.

Arizona. |

The hind femora and tibiee bristle with long stiff and erect black

sete and more decumbent whitish hairs; the femora are some-

what swollen beneath near apical third, with about two suberect

spiniform teeth ; the tibie are quite short and strongly sigmoid,

being everted toward tip and inverted and narrower toward base ;

the last two joints of the tarsi are testaceous. This distinct

species is represented before me by a rather large and homoge-

neous series.

The antennal scape in this genus is smaller than in any other

type of Rhynchophora known to me, being shorter and narrower

than the second joint, to which it is attached axially as in Apion.

LeConte has correctly given five small subequal joints following

the second, but there is another broader joint properly belong-

ing to the funicle and closely adjacent to the club, which was not

observed by that author, so that the funicle is T-jointed, as in

Zygopini; the large curved uncus at the apex of the tibiz is

also similar to that of the Zygopini.

APPENDIX.

The species described by me under the name T'richochrous ex-

aguus (Col. Not. VI, p. 497) is probably the same as the Listrus

Serrugineus of Gorham (Biol. Cent.-Amer., IIT, 2, p. 330). Mr.

Gorham is however gravely in error in assigning the species to

Listrus, for the spines of the tibie are perfectly evident and, be-

sides, the absence of “upright pile on the body above” is by no

means a distinguishing feature of Listrus, since there is a large

division of Trichochrous (Pristoscelis { Gor, ), which also has no

‘trace of erect hairs.

It is probable also that Daeweltis subovalis Csy. a. 6.) p. 670);

is identical with the Listrus impressus of Gorham (Il. c., p. 329),

although the measurement of Mr. Gorham is too small (1/ mm.)

and the generic reference altogether erroneous. It bears no re-

semblance to Listrus canescens, which is a purely Californian

species not occurring in Mexico. Possibly Mr. Gorham alluded

to LZ. senilis, a uniformly and densely clothed species which un-

doubtedly extends its range well into Mexico, but to which he

does not seem to refer.

If the Listrus punctatus of Gorham, is in reality a Listrus the

name is preoccupied by Mannerheim, provided also the species of

the latter author is a true Listrus. JI have seen neither of them

and can therefore give no opinion.

It is probable that the genus Alymeris Csy. (1.¢., p. 600) is the

same as Melyrodes Gorh.

The following species was overlooked in my revision of the

Melyrinee :—

Dasytes parvicollis Mann.—Elongatus, subcylindricus, supra nigro-sneus,

remote subtilius punctulatus, dense griseo-pubescens, subtus niger, capite

minore [Jaticollis] rotundato, thorace elytris angustiore, subrotundato, elytris

dorso subconvexis. Longit. 144 lin.; Latit. 4g lin. Habitat in California.

D. Tschernikh.

I cannot give even a doubtful surmise as to the relationship of

this species from the description, though it is more probably a

Trichochrous than a Dasytes. :

TE,

My attention was recently called to a paper by Mr. Pic, pub-

lished in the ‘‘ Revue Scientifique du Bourbonnais VII,” in which

Coleopterological Notices, VII. 683

the genus Anthicus has been divided into some sixteen named

subgeneric groups, based solely upon such subsidiary characters

as size of the body and form of the prothorax. I am unable to

state the true value of these names, because the anatomical struc-

ture of the pro- and mesosterna is unknown to me, but in one

case it seems that the name proposed by Mr. Pic chances to have

for one of its types the identical species assumed by me for the

type of Hemantus. Mr. Pic’s name “ Trapezicomus ” for Anthicus

floralis will however also possibly have to give way to ‘‘ Omona-

dus,” proposed by Mulsant many years before (Nat. Hist. Col.

Fr., Colligéres, 1866, p. 104). It is also possible, however, that

neither of these names will have to supplant Hemantus, for under

Trapezicomus Mr. Pic, in addition to floralis, groups also rujives-

tis, belona and bedeli of Algeria, the first two of which possibly

and the last probably will be found to be generically different

from floralis when the form of the mesosternum is investigated,

and, under the name Omonadus, Mulsant includes also bifasciatus,

based simply upon the form of the prothorax, truncate head and

position of the eyes; as these are the same in both floralis and

bifasciatus it matters not which we take for the generic type, and

the name Omonadus can therefore be assumed to apply to bifas-

ciatus, a species which a study of the mesosternum will probably

prove to differ generically from florals.

Mr. Pic regards bastilaris Say, as the species allied to floralis

but without the thoracic tubercle, but we cannot absolutely as-

sume this, in view of the general vagueness of Say’s descriptions ;

Say may just as likely have overlooked the very minute tubercle

or regarded it as spurious, and, as I believe there are several

forms allied to floralis but devoid of tubercle, it would simplify

the case to assume that the basillaris of Say, is identical with

floralis. It was with this object in view that I gave the synonymy

of floralis (Col. Not. VI, p. 683).

When the really important anatomical characters of the Euro-

pean species can be studied, several of the names proposed by

Mulsant and Pic will be found to stand for distinct genera, but

the rest must fall into synonymy. I cannot find that any of the

American genera are identical with those of Europe with the ex-

ception of Hemantus.
