leave a rudimentary medial spine in the centre) ; the shield is divided

down its centre by a raised longitudinal (dorsal) ridge, from which

radiate 7 diverging ribs (transversely wrinkled), whose rounded ex-

tremities reach the lateral and posterior border.”’

Diagnosis. —Carapace bivalvular, each valve

oblique by subovate in outline; hinge-line

straight and shorter than the greatest length

of the shield. Anterior extremities slightly

gaping, posterior extremities somewhat pro-

duced, incurved, or truncate. Rostrum ab-

sent or not observed. The cephalic and

anterior portion of the thoracic area marked

by various regularly and symmetrically ar-

ranged nodes, two of which bear the optic

spots. Nuchal furrow more or less distinct.

The thoracic portion of each valve bears one

or two longitudinal, somewhat curving lateral

ridges or carine. Abdomen naked, composed,

so far as known, of 6 somites, which are

furnished with short spinules or prickles on

their dorsal surface. Caudal plate short and

produced into a stout telson. Lateral spines

or cercopods narrow and longer than the

telson. (Hall & Clarke, Pal. New York, vol. 7, p. liv.)

Estheria, Ruffell, 1857; Mus. Senckenberg, vol. 2, p. 119.

Diagnosis.—Carapace bivalvular, the outline of each valve being sub-

circular, obliquely oval, or subquadrate. Beaks generally anterior,

sometimes subcentral. Dorsal or hinge-line straight, shorter than the

greatest length of the valves. Surface rarely smooth, usually with

concentrie lines of growth, the interstitial spaces being often orna-

Diagnosis.—Body elongate. Cephalon about + the length of the body,

subquadrate in outline, gently convex. Eyes large, reniform, situated

somewhat anteriorly, and within them lie two ocular puncte or ocelli.

Oral aperture surrounded by 5 pairs of cephalic appendages in front of

which is a pair of minute antennules. The first 3 pairs of appendages

or gnathopods are of approximately the same length, the joints of the

4th pair being more elongate, and the 5th pair being developed into

powerful swimming appendages, the last two segments of which are

very broad and flat. Behind the mouth lies an oval plate (metastoma).

Abdomen upon the dorsal side composed of 6 segments, the first of

which corresponds to the operculum of Limulus. Upon the ventral

surface there are but 5 segments apparent, all of which are divided by

a median suture, the first two bearing median processes extending

posteriorly. The first segment also bears a series of symmetrically

arranged median plates, which may be connected with the genital

apparatus. Post-abdomen composed of 6 tapering segments and a

long slender caudal spine. (Hall & Clarke, 1888; Pal. New York,

Gen. Char.—*‘ The carapace-valves are oblong; truncate behind, with a

slight curvature of outline; boldly rounded in front; either straight

or somewhat curved on the ventral border ; slightly on the dorsal edge;

a slight umbo takes the place of the antero-dorsal angle, from whence

two conspicuous ridges (hollow within) pass along the surface of the

valve ; one directly across the valve to the antero-ventral angle; the

other, and longer one, passes diagonally to the postero-ventral angle ;

these ridges divide the convexities of the valves in three, unequal,

triangular, smooth, sloping areas; the anterior space is the smallest

and nearly semi-circular ; the middle one has its apex at the umbo,

and its base along the ventral margin ; and the posterior space is based

on the hinder margin, and reaches along the dorsal region to the umbo.

The surface of the valve is marked with 10-13 ? delicate ridges.”’ .

Gen. Char.—Carapace inequivalved ; somewhat resembling a tamarind-

stone; valves smooth, convex, nearly oblong, longer than broad,

inequilateral, posterior half broadest; dorsal border straight; basal

margin nearly semicircular. Anterior and posterior sides oblique

above, rounded below. Valves united along their dorsal borders by a

North American Palzozoic Crustacea.

simple linear hinge; the two extremities of the hinge-border form

angles with the anterior and posterior borders of each valve. The

right valve larger than the left, being broader and overlapping com-

pletely the ventral border of the opposite valve, and to some extent its

anterior and posterior borders. This overlap forms a thick blunt keel

to the closed carapace. Rather above and in front of the centre of

each valve, and on its most convex portion there is a raised, circular,

or sub-oval swelling ; on the interior surface of the valve this is marked

by a corresponding pit. Type L. Britannica, Rouault.

Diagnosis.—Carapace sub-quadrate in outline, composed of two valves

which come into contact at the apices of two broad, sub-triangular

extensions, situated on the dorsal line opposite the eye-nodes, forming

a short and broad anterior, or rostral cleft, and a long posterior cleft.

Rostrum not observed. The posterior dorsal cleft was covered either

by a single elongate plate, with each margin of which the valves were

in symphysis, or, as is more probable, by a double plate, divided by a

median suture. Test broadly infolded on the lower surface, thickened

and produced into a conspicuous and acute posterior spine. Posterior

margin incurved and produced into a short spine at the dorsal line.

Surface with a single strong carina on each valve. Abdomen consist-

ing of two somites of which the posterior is the longer. Post-abdomen

with a broad caudal plate, which is produced into a relatively short

telson. Lateral spines long and setaceous.

Gen. Char.—Carapace minute, bivalved, either equivalved or nearly so,

convex, more or less oblong, often approaching Leperditia in shape, by

the sloping of the dorsal angles ; hinge-line straight, sometimes nearly

as long as the valve. Surface of each valve usually impressed on the

dorsal region, either medially or towards the anterior extremity, with

a vertical sulcus, variable in size, sometimes barely visible, sometimes

passing into, or even merely represented by, a navel-like pit; and

sometimes the sides of the sulcus are swollen and even raised up into

tubercles.

Valves semicircular, suboval, or even nearly circular. Dorsal line

straight, generally with a well-defined sub-central sulcus and a more

* extends around the valves from the antero-dorsal to the postero-dorsal

angle. The border is often striated in a radial manner, and in most

cases terminated by a marginal ‘‘frill,’’ or by a plain narrow border,

usually directed slightly outwards. The main body of the border,

however, curves inward to near the plane of contact between the two

valves, thus forming a deeply concave outer area. Hingement simple.

Surface reticulate, granulose or smooth.

II.—Coleopterological Notices.

BY THOMAS L. CASEY.

Read October 7, 1889,

The following pages embody the results of a number of detached

studies in various parts of the Coleopterous series, and are confined,

in general, to the fauna of America north of Mexico. The family

Phalacride, and the genera Thinobius, Aploderus, and Limnichus

are treated monographically.

I have to acknowledge my appreciation of the kindness shown

me by the authorities of the Museum of Comparative Zoology,

at Cambridge, Mass., under the curatorship of Dr. H. A. Hagen,

for permission to examine the types of Dr. LeConte, without

which no systematic work of scientific value could have been accom-

plished.

I am also indebted to Prof. C. V. Riley for the use of the

material of the National Museum, which has been of great service

in determining geographical distribution in the Phalacride, and to

Dr. D. Sharp, and Messrs. E. A. Schwarz, Otto Lugger, and H. F.

Wickham, for valuable specimens.

Norte.

The introduction of new names for parts of an insect, when names already

in use will serve just as well, should be avoided, and, as the term hypomera has

been employed by me in many descriptions for the inflexed sides of either the

pronotum or elytra, by prefixing the proper adjective, it may be objected that

epipleure would serve the same purpose, and that the new word is therefore

unnecessary. I have consequently determined to restrict the meaning of hypo-

mera, so as to denote simply the inflexed sides of the pronotum, reserving the

word epipleure to denote the inflexed sides of the elytra, and the word hypo-

pleure to designate the lower beaded margin of the epipleure, which, although

generally small and sometimes obsolete, occasionally becomes larger and rather

conspicuously modified. It is hoped that this will tend to promote conciseness,

and that the consequent reduction of words will warrant the proposed nomen-

clature.

By referring to the table of species published by Dr. Horn (Trans.

Am. Ent. Soe., X, p. 273), it will be seen that the following form is

not closely allied to any hitherto known. It is extremely slender,

parallel and convex, and is distinguished by the nine series of ely-

tral punctures being very distinctly traceable.

P. cylindrica n. sp.—Parallel, very convex, rather more than three

times as long as wide, uniformly blackish-piceous above; under surface and

legs bright rufous; integuments highly polished ; margins fimbriate. Head

short and broad, feebly convex, nearly four-fifths as wide as the prothorax,

very finely, sparsely and unevenly punctate, the punctures in the form of

minute strongly embossed rings ; eyes large, finely faceted; antenne slender,

compressed, cylindrical ; joints four to eleven very compactly joined, second

three-fifths as long as the third, the latter longer than the fourth, five to ten

subequal, nearly as long as the third, the eleventh longer. Prothorax scarcely

more than one-third wider than long; sides very feebly convergent from base

to apex and just visibly arcuate; basal angles—viewed laterally—broadly

rounded, apical narrowly rounded ; base and apex transversely truncate, the

former with a fringe of short pointed closely placed sete; disk transversely,

very strongly convex, very narrowly explanate along the sides, margined at

the sides and apex with a wide elevated bead which is completely obsolete

throughout the basal margin, very minutely, sparsely punctate; punctures

rather unevenly distributed, annulate; median impressed line completely

obsolete. Scutellum very minute, transversely triangular. lytra fully as

wide as the base of the prothorax, twice as long as wide, three and two-thirds

times as long as the prothorax ; sides parallel and straight; together abruptly

subtruncate at apex, the truncation broadly arcuate; disk cylindrically and

strongly convex, with nine distinct and almost even series of fine distant sub-

asperate punctures, the punctures of the second series from the suture much

larger and with longer setz, those of the fourth series also more distinct but

much smaller than those of the second ; intervals impunctate. Length 7.0 mm. ;

width (base of prothorax) 2.1 mm.

remarkably distinct. The third and fourth segments of the abdomen

rently shallow perforation, which is situated in the middle near the

base, and about as wide as the length of the fifth tarsal joint; they

are similar in form and position; the bottom is flat and densely

spongiose, and the anterior margin bears a fringe of long closely-

placed subrecumbent sete, which extend over and partially protect

the sensitive spongiose area. The long second segment is more

densely pubescent than the remainder of the abdomen.

STAPHYLINID.

BLEDIUS Leach.

A partial revision of the North American species of this extensive

and interesting genus has been published by Dr. LeConte (Trans.

Am. Ent. Soc. VI, p. 217 et seq.), and, although apparently somewhat

hastily drawn up, the descriptions there given will serve in most

cases for purposes of identification. The species as a rule are much

larger in size and more open in their habits than those of Trogo-

phleeus, and it is almost certain that the proportion of known to

unknown forms is much greater than in that genus, but in spite of

this the number of species existing in America north of Mexico will

probably be found to be in the neighborhood of one hundred and

fifty. While, therefore, the time is not yet ripe for a useful mono-

graph of our species, it is highly desirable that, the large number of

species discovered in recent years should be assimilated, and the

revision above alluded to forms a convenient guide for the distribu-

tion of them with regard to their systematic relationship.

The groups adopted by LeConte rest in several cases upon char-

acters which have been inaccurately stated, and therefore have not’

the value which apparently belongs to them. The armatus group,

for instance, is quite composite, the coxal fissures being open in

some and shorter and closed in others. When open, however, as in

strenuus, they are not of the same form as in the annularis group,

where they are longer, acutely triangular and gradually more widely

open toward the coxe. The antenne in cribricollis and monstra-

tus, with their three-jointed club, are quite different in structure

from those of armatus and strenuus.

The definition, also, of the cordatus group by the form of the

basal angles of the prothorax is unfortunate, for the form of these

angles varies from the broadly rounded and completely obsolete as

42 Coleopterological Notices.

in basalis, to the distinct and even slightly prominent as exhibited

in cordatus. There is an undoubted bond of affiliation between the

species associated by the author in the group, but it cannot be the

form of the basal angles. It would be better to separate them as

a group on the longer second antennal joint, which is invariably

longer than the next two combined, and the convex head, with

small and extremely feeble antennal prominences, or by the small

unemarginate labrum, with the apical edge finely and strongly

reflexed, or even by the peculiar system of coloration.

The very decided character separating the mandibularis group is

not entirely constant, for in several, if not all the species assigned to

it, the acute lateral edge is present near the apex, and in some species

not assignable to it, as monticola and dimidiatus, the acute margin

becomes obsolete before reaching the base, and in the latter is totally

absent, almost throughout the basal sinuation.

These are matters, however, which must be reserved for a more

complete study, and the new species here brought to notice are dis-

tributed in the groups as limited by LeConte, a list showing their

relative positions being given under each heading.

It should be said in conclusion that the tarsi are not three-jointed

as stated in the books, but more properly four-jointed. In the

species allied to armatus, all four joints are perfectly free and dis-

tinct, but the basal joint becomes subanchylosed to the second in

several species, notably in the semiferrugineus group, and in the

annularis group the anchylosis is generally complete, the tarsus

appearing to be three-jointed; even here, however, the suture can

often be plainly seen.

Group 1.—mandibularis.

No additional species assignable to this group have been reported,

and it is highly probable that brevidens Lee. will prove to be a

synonym of mandibularis Er., the specimens before me showing all

degrees of development of the mandibular tooth.

The magnitude of the triangular incision of the eighth segment in

the males of this genus appears to be variable at will, the segment

being composed of two overlapping parts, the edge of one forming

an oblique line from one side of the apex to the opposite side of the

base. When the two parts are pushed apart laterally, the notch at

the apex becomes deeper, and as they are closed together it becomes

smaller, preserving however the same relative form.

Group 2.—armatus.

The succession of species, of which a very large proportion are

described below, may be stated as follows :—

armatus Say. agonus 0. sp.

strenuus 0. sp. ineptus n. sp.

furtivus n. sp. politus Er.

cribricollis Lec. flavipennis Lec.

monstratus n. sp. lectus n. sp.

eximius nN. sp. tenuis n. sp.

cuspidatus Lec.

B. armatus Say.—Oxyt. arm. Say, Journ. Ac. Phila. III, p. 155.—Rather

robust and convex, black; elytra dark rufo-piceous, blackish toward suture

and base; abdomen slightly paler at the apex; legs and antenne dark piceo-

rufous, the latter piceous toward apex; head and prothorax moderately shin-

ing, rather coarsely and very strongly reticulato-granulose ; abdomen polished,

finely reticulate. Head distinctly narrower than the prothorax, very feebly

convex, with a few very small, feeble and indistinct punctures in the lateral

depressions, having, on a line through the middle of the eyes, two large,

approximate, distinct, but not very strongly elevated tubercles, the surface

behind them very feebly impressed; epistomal suture fine, impressed, very

distinct ; antennal prominences very large and strongly elevated ; each apical

angle of the epistoma with a strong erect process, the apex of which is reflexed;

antenne long and rather slender; second and third joints equal in length, the

latter as long as the fifth and sixth together, outer joints gradually more robust,

the tenth scarcely perceptibly wider than long. Prothorax as wide as the base

of the elytra, scarcely more than one-sixth wider than long; sides in apical

three-fifths parallel and nearly straight, then broadly rounded to and through

the base, the latter less strongly arcuate, the basal and lateral angles entirely

obsolete ; apical right, rather narrowly but distinctly rounded; apex nearly

transversely truncate; disk sparsely and very unevenly punctate, the punc-

tures impressed, very distinct but not very coarse; median groove deep, im-

pressed, conspicuous. Hlytra quadrate, toward apex scarcely perceptibly wider

than the prothorax, about one-fourth longer than the latter, rather strongly

impressed near the suture toward base, not very densely or coarsely punctate,

the punctures deep and very distinct, separated by about twice their own

diameters ; pubescence rather sparse, moderate in length, coarse. Abdomen

slightly narrower than the elytra, rather sparsely, finely punctate, the im-

pressed areas impunctate; under surface finely, more densely punctate, with

long coarse conspicuous pubescence. Length 5.5-6.0 mm.

New Mexico (Albuquerque). Mr. H. F. Wickham.

The above rather full diagnosis is given, as there has been more

or less indecision in the identification of this species. The descrip-

tion is taken from the male, the female differing very slightly, the

44 Coleopterological Notices.

tubercles of the front and epistoma being rudimentary. The hypo-

mera are very feebly impressed along the outer margin; they are

wide, and the apical width is equal to the length of the short, almost

completely closed coxal fissures, and two-thirds as wide as the

width at the fissures; the suture is obsolete, but traceable from

differences in the form of reticulation. The mentum is distinctly

but moderately impressed throughout the width toward base, the

short coriaceous hypoglottis being separated by a fine deep suture.

In the two following species only those characters are mentioned

which differ from the corresponding ones of armatus; in other re-

spects they are similar.

B. strenuus n. sp.—Robust, moderately convex, black, the elytra some-

times dark piceo-rufous as in armatus. Head much narrower than the protho-

rax ; epistomal suture very coarse, deep and distinct ; antenne piceous-black

throughout, nearly as in armatus. Prothorax slightly wider than the base of

the elytra, one-third wider than long; sides in slightly more than apical two-

thirds nearly straight and very feebly but distinctly divergent from the apex,

then strongly convergent, at first nearly straight then broadly rounded into

the base, without trace of basal angles, the base more feebly arcuate ; lateral

angles obtuse but very narrowly rounded and distinct, apical very slightly

obtuse, rather narrowly but distinctly rounded ; apex transversely truncate ;

punctures rather more densely and evenly distributed than in armatus. Elytra

very slightly wider than long, at apex scarcely perceptibly wider than the

prothorax, the sides slightly divergent and nearly straight, between one-fourth

and one-third longer than the prothorax. Abdomen very slightly narrower

than the elytra. Length 6.0 mm.

California.

The description is taken from the male, of which I found a single

specimen in the brackish marsh behind the ocean beach at San

Francisco. There is an entirely similar specimen from the same

locality in the cabinet of Dr. LeConte.. With these I have asso-

ciated a large number of specimens taken at Los Angeles, which

differ only in the sides of the prothorax being parallel and not diver-

gent from the apex as in the San Francisco specimens—they, how-

ever, probably represent a variety, as the coxal fissures are distinctly

shorter and more nearly closed. The species differs from armatus

in its much more transverse prothorax, rather more robust form,

and distinct lateral prothoracic angles.

The hypomera are wide, very feebly impressed laterally, the apical

width being slightly more than one-half that at the coxal fissures ;

the latter are longer than in armatus, being nearly as long as the

width of the hypomera at their apex, and are distinctly open, the

sides however being parallel, and not angulate and more open

toward the coxe, as in the annularis group. The sutures are

entirely obsolete, and the mentum is nearly as in armatus.

B. furtivus n. sp.—General form and sculpture nearly as in armatus, the

tubercles of the vertex being smaller and more approximate, and the epistomal

processes shorter ; outer joints of antenne very slightly more transverse. Pro-

thorax scarcely perceptibly narrower than the base of the elytra, rather strongly

transverse, two-fifths wider than long; sides parallel and straight, strongly

convergent in basal third and nearly straight, the basal angles very obtuse

and very broadly rounded, but more distinct than in strenuus; lateral angles

obtuse but very narrowly rounded and distinct, apical right and very broadly

rounded, the apex broadly and very distinctly arcuate throughout the width,

otherwise uearly as in strenuus. Elytra scarcely as long as wide, about two-

fifths longer and, near the apex, fully one-fourth wider than the prothorax,

the sides distinctly divergent. Abdomen entirely impunctate along a broad

and distinct median line, finely and rather densely punctate beneath. Length

5.0 mm.

Oregon (The Dalles). Mr. H. F. Wickham.

Although the abdominal punctures are sparser along the middle

in armatus, there is no well-defined line in which they are entirely

absent, as in furtivus; this line is, however, broad and almost

entirely free from punctures in strenwus,

This species, the description of which is taken from the male,

differs greatly from armatus in its much shorter and more trans-

verse prothorax, with distinct lateral angles, and from strenuus in

the broadly rounded apex and apical angles of the same part. The

prosternal sutures are more distinct than in either of the preceding

species, and because of the greater depression of the apical angles

of the pronotum, the hypomera are, at apex, distinctly less than

one-half as wide as at the coxal fissure; the latter is slightly shorter

than the hypomeral width in continuation of it, and is narrowly

open, being intermediate between the same part in armatus and

strenuus. The hypomera are not distinctly impressed externally.

The mentum is nearly as in the two preceding species.

The three species armatus, strenuus and furtivus, although

closely allied, are almost undoubtedly distinct; if however this

should prove not to be the case, the structure of the prosternum

and hypomera must be considered of very little value, even in the

separation of species.

B. monstratus n. sp.—Rather slender and convex, parallel, dark testa-

ceous ; abdomen dark piceous-brown ; elytra paler, flavate throughout; legs

and antenne flavate; head strongly shining, reticulato-granulose, the median

tubercles, antennal prominences and apical part of the epistoma highly polished

and not reticulate; pronotum polished, very feebly reticulate near the punc-

tures; abdomen moderately shining, very strongly reticulate. Head very small,

much narrower and shorter than the prothorax ; eyes moderately prominent ;

on a line through their apical third there are two very approximate prominent

tubercles, behind and between which there is a short feeble canaliculation ;

between them and the large prominent antennal tuberculations there are a few

small, rather distinct punctures ; suture short, transverse, feeble, not impressed,

situated immediately before the tubercles of the vertex; apical angles of the

epistoma tuberculate, the tubercles gradually obsolete posteriorly, and slightly

more approximate than the angles; antenne rather short and slender, the

three last joints abruptly wider forming a club; second distinctly longer than

the third, four to seven moniliform and subglobular, eighth slightly wider,

transversely oval, ninth and tenth strongly transverse, eleventh short, ovoidal,

slightly narrower than the tenth, longer than wide. Prothorax large, about

one-fourth wider than long; sides from near the apex to basal fifth parallel

and straight, then abruptly, broadly rounded into the base, without trace of

basal or lateral angles, the base broadly distinctly arcuate, the apex trans-

versely truncate; apical angles right and distinctly rounded; disk extremely

coarsely punctate, the punctures very strongly and broadly impressed, deep,

distant by rather less than their own diameters anteriorly, becoming much

finer and sparse toward base; median groove wide, entire, very broadly and

deeply impressed, conspicuous. Llytra scarcely as long as the prothorax and

very distinctly narrower, scarcely as long as wide, very broadly and just visibly

impressed on the suture at the base; sides very feebly divergent ; surface very

finely and densely punctate, the punctures distant by nearly twice their own

diameters ; pubescence dense, moderate in length. Abdomen just visibly wider

from base to apex, at which point it is fully as wide as the elytra; sides

straight; surface very finely, feebly, indistinctly and rather sparsely punc-

tate, rather finely, more distinctly and densely so beneath. Length 3.84.3 mm.

California (San Francisco). .

The type of this interesting and very distinct species is a male,

but possesses no decided sexual modification at the apex of the

abdomen. It is closely related to cribricollis Lec., but is immedi-

ately distinguishable by its very large prothorax and small elytra.

It should form, together with eribricollis, a group distinet from the

armatus group of LeConte, because of its very short completely

closed coxal fissures, and three-jointed antennal club.

The apical angles of the pronotum are abruptly and strongly

deflexed, the hypomera wide, very deeply and broadly concave

throughout, the coxal fissures extremely short, closed and directed

mentum is almost flat, shining and reticulate. The color occasion-

ally becomes very pale flavate-brown throughout.

strong, their apices externally finely and strongly margined with an elevated

bead; antennze moderate in length, rather strongly, gradually incrassate ;

combined, tenth fully three-fourths wider than long. Prothorax just visibly

narrower than the base of the elytra, one-fourth wider than long; sides in

rather more than apical two-thirds parallel and straight, then convergent and

straight for a short distance, then broadly rounded into the base without trace

of basal angles; base transverse; apex just visibly arcuate; apical angles

right and extremely narrowly rounded, lateral very obtuse, broadly rounded

and not distinct ; disk rather coarsely, sparsely and very unevenly punctate ;

median groove wide, very deeply impressed, entire and conspicuous. Elytra

fully as long as wide, one-fifth wider and one-half longer than the prothorax ;

sides nearly straight, slightly divergent; surface very feebly impressed on

each side of the suture at base, rather coarsely, moderately densely and deeply

punctate, the punctures generally separated by nearly twice their own widths 5

pubescence rather long, distinct but not very dense. Abdomen at apex nearly

as wide as the elytra, at base much narrower; sides straight and distinctly

divergent; surface finely, rather sparsely punctate, finely and densely so

beneath, with the surface finely granulato-rugulose and somewhat dull.

Length 5.5 mm.

California (San Diego).

The hypomera are flat, but strongly depressed below the lateral

edges, the latter being very prominent and acute throughout; at

apex the width is fully three-fourths that at the fissures, which are

but slightly shorter than the adjacent hypomeral width, and nar-

rowly but very distinctly open; the prosternal sutures are almost

completely obliterated but rather distinctly traceable. The mentum

is shining, coarsely and very strongly reticulate, and broadly im-

The description of this very distinct species is taken from the

The mentum is broadly and deeply impressed especially toward

The hypomera are wide, rather flat but very feebly impressed

near the lateral edges, the coxal fissures short, about two-thirds as

long as the adjacent hypomeral width and narrowly but distinctly

open; the prosternal sutures are almost completely obsolete. The

mentum is flat, scarcely perceptibly and indefinitely concave, coarsely

but very feebly reticulate, polished, the terminal membranous hy po-

glottis strongly developed, nearly one-third as long as the chitinous

portion. The anterior angles of the epistoma are finely and very

strongly tuberculate in the male.

This species should be placed near politus. It is rather closely

allied to agonus, but differs in its distinctly narrower head, more

broadly rounded apical angles of the prothorax, the latter being

distinctly less transverse, and in its shorter, more coarsely deeply

and densely punctate elytra.

California (Sonoma Co.).

The hypomera are narrowly and strongly impressed along the

outer edge, the width at the apex being fully two-thirds as great as

at the fissures; the latter are very short, scarcely two-thirds as long

as the adjacent hypomeral width, and are distinctly and rather

widely open ; the prosternal sutures are almost completely obsolete,

although traceable. The mentum is shining, coarsely and strongly

reticulate and very feebly concave, the hypoglottis very short.

Belongs near flavipennis Lec., from which it is at once distin-

guishable by its narrower form, less distinct prosternal impressions

Nevada.

The hypomera are distinctly narrowly impressed near the margin,

and are rather wider than the distance thence to the coxe, the coxal

fissures being narrowly open and short. The mentum is broadly

feebly impressed. The anterior angles of the epistoma, at least in

the male, are finely and feebly tuberculate. It is closely allied to

lectus, but differs in its more slender form and smaller more trans-

verse prothorax.

The prosternal sutures are obliterated and the mentum is mar-

gined at apex with a very thick convex bead—hypoglottis—sepa-

rated by a fine deep groove.

near the lateral edge posteriorly, the sutures distinct, the fissures

moderate in length and not entirely closed, the posterior edge below

the anterior appearing closed when viewed vertically, but widely

open near the coxe. The mentum is moderate, shining, coarsely

reticulate and nearly flat.

This very distinct and beautiful species belongs. because of its

distinct sutures and half-closed coxal fissures, in the semiferrugt-

California (Lake Co.). Mr. Fuchs.

This species is allied to fumatus Lec., but differs greatly in its

smaller eyes, straight and not broadly rounded sides of the pro-

thorax, deeper and more distinct punctuation of the head, and,

especially, in the structure of the antenne which in fumatus are

54 Coleopterological Notices.

more slender, and much more feebly incrassate, with joints six and

seven distinctly longer than wide, and eight fully as long as wide,

nine and ten much less abruptly longer than eight; in the present

species the eighth joint is nearly one-half wider than long. The

description is taken from the only specimen which I have seen, and

this is unfortunately the female, but the above comparison has been

made with the same sex of fumatus.

The hypomera are flat, rather wide, the apical width fully one-

half that at the fissures, the latter rather long but slightly shorter

than the hypomeral width in continuation of them, and are almost

completely closed; the prosternal sutures are very distinct, being

defined by a fine elevated line. The mentum is shining, coarsely

reticulate, finely, deeply impressed along the base and unusually

coarsely, deeply but very sparsely punctate.

B. gravidus n. sp.—Moderately robust, rather convex, piceous; elytra

bright rufous, feebly clouded with piceous toward base, and slightly along the

suture; abdomen above and beneath dark rufo-testaceous, the apices of the

segments clouded with piceous; head finely reticulate, feebly shining; pro-

notum distinctly reticulate, rather strongly shining, the reticulation obsolete

posteriorly toward the sides, the surface becoming polished ; abdomen polished,

finely, very feebly and subobsoletely reticulate. Head rather distinctly nar-

rower than the prothorax, feebly convex, finely, sparsely and not very dis-

tinctly punctate, not tumid in the middle, the median puncture small, rounded,

feebly impressed, not surrounded by a polished area; antennal tuberculations

large, short, moderately prominent, polished toward apex; suture fine, feebly

arcuate, not impressed ; apical angles of the epistoma distinctly tuberculate ;

than long; sides from apical fourth to just behind the middle parallel and

straight, then convergent and just visibly arcuate to the basal angles, which

are very obtuse, rather broadly rounded although somewhat definable; lateral

angles obtuse, very broadly rounded and not distinct; sides in apical fourth

convergent and strongly arcuate, the angles at the apex being slightly obtuse

and scarcely at all rounded; apex transversely truncate; base just visibly

arcuate ; disk convex, finely, sparsely and unevenly punctate, the punctures

distinct but not very deep, the median groove rather fine but deeply impressed

suture at the base, rather finely but distinctly and densely punctate, the

punctures separated by but very slightly more than their own diameters ;

pubescence moderate in length. Abdomen parallel, distinctly narrower than

the elytra, rather finely but not very densely punctate toward the apices of

the segments, polished and moderately densely punctate beneath. Length

New Mexico (Albuquerque). Mr. H. F. Wickham ; Utah.

The hypomera are broadly, very feebly impressed along the outer

edge, the apex about three-fifths as wide as the width at the fissures,

the latter rather long, fully as long as the adjacent hypomeral width, -

and almost completely closed, the prosternal sutures distinct. The

mentum is not visibly punctate, shining, coarsely reticulate and

distinctly impressed along the base.

The description of this distinct species is taken from the male,

the sixth segment being evenly emarginate in circular are, the

emargination simple, not margined with membrane, and about five

times as wide as deep; the surface at the sides of the emargination

bears several very long, erect, interlacing sete. It should-be placed

near rubiginosus Er.

The punctures of the pronotum vary in size, and in some speci-

mens are slightly coarser.

B. assimilis n. sp. (Fauvel MS.).—Rather slender and convex, black ;

elytra piceous; legs and antenne pale flavate, the latter infuscate except

toward base; head and prothorax finely, densely granulate, feebly shining ;

rower than the prothorax, rather convex, finely, very obsoletely punctate, not

tuberculate; median fovea small, feebly impressed; antennal prominences

small, feeble; suture fine, distinct, not impressed, arcuate; epistoma simple ;

antennze rather long, moderately and gradually incrassate ; second joint dis-

tinctly longer than the third, four to six decreasing in length, the latter dis-

tinctly wider than long, seventh longer, slightly wider than long, eight to ten

increasing in length, the latter longer than wide, eleventh nearly twice as long

as wide, shorter than the two preceding together ; last three joints together as

long as the preceding six. Prothoraxr slightly but distinctly narrower than the

base of the elytra, about one-fourth wider than long; sides in anterior two-

thirds parallel and straight, then convergent and nearly straight to the basal

angles, which are obtuse, narrowly rounded, rather distinct but not at all

prominent; lateral angles obtuse, narrowly rounded and rather distinct, apical

right and distinctly rounded ; apex almost transversely truncate; disk very

densely and somewhat deeply punctate, the punctures moderate in size, sepa-

rated by scarcely their own diameters but slightly sparser toward the median

impunctate line, which is entire and moderate in width, the median groove

being completely obsolete. lytra nearly as long as wide, two-fifths longer,

56 Coleopterological Notices.

and rather more than one-third wider than the prothorax, feebly impressed

near the suture toward base, rather finely punctate, the punctures distinct,

rather smaller than those of the prothorax, and separated by nearly twice their

own diameters. Abdomen slightly narrower than the elytra, gradually wider

from base to apex, finely, somewhat densely punctate, beneath polished, finely,

somewhat densely punctate. Length 3.3 mm.

Illinois; Iowa.

The description is taken from the male, and the sexual characters

at the apex of the abdomen are, as usual in the semiferruginevs

group, very strongly marked, in this case more remarkable than in

any other species which I have seen, and reminding us somewhat

of the male modification in Apocellus.

The sixth segment is broadly, strongly emarginate in circular are

nearly throughout the width, the emargination bordered with a

wide and thin, very slightly inflexed membrane; at each side of the

emargination there is a small, acute, pointed tooth; the seventh

segment is slightly produced and rounded in the middle, the eighth

as usual obliquely divided, the two overlapping portions having an

acute apical incisure, which can apparently be varied at will.

The hypomera are wide, flat, the suture distinct; the coxal fissures

very short, almost completely closed; the mentum shining, reticu-

late, very feebly, transversely impressed near the base. The species

should be placed immediately after nitidicollis Lec.

hypomera are about one-half as wide as the distance thence to the

cox, nearly flat anteriorly, strongly impressed along the middle,

the sutures almost completely effaced, the coxal fissures very long

and widely open. The mentum is very deeply impressed in the

For the present villosus may be associated with laticollis.

B. nebulosus n. sp.—Rather robust, nearly parallel, black ; elytra pale

rufo-ferruginous, indefinitely clouded with piceous-black toward the suture,

The hypomera are moderate in width, deeply concave throughout,

the lateral edges being very prominent; sutures distinct; coxal

fissures moderate in length, widely open. The mentum is large

and extremely feebly concave throughout its extent; it is rather

shining and coarsely reticulate, the membranous hypoglottis very

short, inflexed and inconspicuous.

Belongs near laticollis, but is well distinguished by its more

shining head and pronotum, the punctures of the latter being better

defined and the basal angles rather more distinct, by its relatively

larger and more finely punctate elytra, less concave mentum, much

wider pronotal hypomera, shorter coxal fissures, and larger but less

prominent eyes,

B. monticola n. sp.—Rather slender, black ; elytra and antennx pice-

ous-black, the latter very slightly paler toward base; legs rufous; head and

prothorax dull, densely granulose; elytra and abdomen polished, the latter

spicuous. Abdomen very slightly narrower than the elytra, finely, sparsely

punctate, rather coarsely and densely so beneath. Length 2.8 mm.

California (Lake Tahoe, 6200 feet).

A small species, quite distinct in its very dense punctuation; the

absence of an acute lateral margin near the basal angles of the pro-

thorax will distinguish it from its nearest allies; it should be placed

near sinuatus Lec.

The hypomera are very broadly, feebly concave and rather more

than one-half as wide as the distance thence to coxe, the sutures

distinct, the coxal fissures moderate in length and widely open. The

mentum is shining, coarsely reticulate and broadly, rather strongly

California (Sonoma Co.).

The unique example represents a very distinct species differing

from any other which I have seen; it may, however, be placed

next after s¢nuatus in the catalogue.

The hypomera are very narrow, scarcely more than one-third as

wide as the distance thence to the coxe, very feebly concave, the

sutures distinct ; the coxal fissures are long and very widely open.

The mentum has a large, moderately deep median impression ; it is

shining and coarsely reticulate, the hypoglottis thin, polished, flat,

not reticulate and rather long, being about one-fifth as long as the

entire mentum, the dividing suture very feeble.

sparsely so beneath. Length 2.5-3.0 mm.

California (Mendocino, Sonoma, and Santa Cruz Cos.).

This species is allied only to gentilis, which it somewhat strongly

resembles in external form, color and lustre. It is, however, a

rather smaller species, with much sparser elytral punctuation, and

much deeper and wider median groove of the pronotum. The men-

tum is not impressed in the middle as in gentilts.

The hypomera are nearly one-half as wide as the distance thence

to the coxe and are flat, except externally and posteriorly near the

lateral margin, where they are narrowly impressed ; the sutures are

distinct, and the coxal fissures long and widely open.

Pennsylvania (Allegheny Co.). Dr. Hamilton.

The hypomera are about one-half as wide as the distance thence

to the coxe and are broadly, rather feebly concave, the sutures fine

and distinet, the coxal fissures rather long and extremely widely

open. The mentum is rather shining, broadly, feebly concave, the

apex being broadly feebly emarginate.

This species belongs near annularis, but differs in its more shin-

ing, more sparsely and distinctly punctate, and decidedly wider and

more transverse prothorax, the hind angles being more prominent,

and in its larger, longer and wider elytra.

Colorado (Garland). Mr. EK. A. Schwarz.

A small species, closely allied to ruficornis Lec., but differing in

its sparser punctuation and rather shorter, more robust antenne.

The hypomera are feebly concave, two-fifths as wide as the distance

thence to the coxe, the sutures fine but distinct. The coxal fissures

are long and very widely open.

Oregon (Huntington). Mr. H. F. Wickham.

This is a rather slender species, allied to ruficornis Lec., but

distinguished by its very much sparser pronotal punctuation, black

antenne, and less opaque lustre.

The hypomera are very narrow, distinctly less than one-half as

wide as the distance thence to the coxe, and rather deeply concave,

the sutures being feeble and not very distinct. The coxal fissures

are very long and widely open. The mentum is broadly, feebly

concave, coarsely reticulate, polished and furnished along the apical

margin with a short flat polished non-reticulate hypoglottis, sepa-

rated by a fine suture.

In ruficornis Lec. the abdomen beneath is much more densely

and coarsely punctate, and the hypomera are wider and almost

perfectly flat, the sutures more distinct.

B. bicolor n. sp.—Black ; prothorax, elytra and antenne brown; legs

flavate ; head and pronotum very finely, densely granulate and opaque; elytra

and abdomen polished, the latter reticulate. Head just visibly narrower than

the prothorax ; eyes rather large but moderately prominent, the sete rather

long; surface rather convex, finely and not distinctly punctate, not tubercu-

late, the median fovea very small and feeble; antennal prominences feeble ;

epistomal suture fine, not impressed; antenne but feebly compressed, rather

strongly incrassate ; second joint much longer and more robust than the third,

but not as long as the next two, three to six subequal in width, decreasing

rapidly in length, the latter but slightly transverse, seven to ten gradually

wider, the former not very abruptly so, the latter one-half wider than long.

Prothorax very slightly narrower than the base of the elytra, scarcely one-third

wider than long; sides in apical three-fifths parallel and nearly straight, then

convergent and broadly, feebly sinuate to the basal angles, which are obtuse

but not rounded and not prominent; lateral angles obtuse and rounded but

very fine but distinct. /ytra nearly quadrate, one-third wider and one-half

longer than the prothorax, very slightly wider toward apex; sides nearly

straight; disk not impressed at base, densely and distinctly, but somewhat

coarsely punctate, the punctures separated by distinctly less than their own

diameters ; pubescence fine, moderate in length and density, cinereous and

distinct. Abdomen broad, but slightly narrower than the elytra and much

wider than the prothorax, finely, not densely punctate, more strongly and

somewhat densely so beneath. Length 3.3 mm.

California (Napa Co.).

A rather small inconspicuous species, allied to ruficornis, but

well distinguished by its peculiar coloration, which is very constant

throughout a series of eight specimens. It is further distinguished

by its sexual characters, the anterior margin of the epistoma being

perfectly devoid of tuberculation in the male. In the corresponding

sex of ruficornis there are two remote and very small tubercula-

tions which, however, are not at the apical angles as in armatus,

but distinctly nearer the middle.

The hypomera are flat, except near the apex of the coxal fissures

where they are feebly impressed ; they are scarcely one-half as wide

as the distance thence to the cox, the sutures being distinct. The

coxal fissures are very widely open. The mentum is exceedingly

feebly concave, the hypoglottis apparently obsolete.

rower; black throughout, legs pale flavate, the cox and femora toward base

picescent ; antenne fuscous, paler toward base; head and pronotum opaque,

extremely minutely and densely granulose; elytra and abdomen polished, the

latter reticulate, the lines very fine, the reticulations strongly transverse and

much smaller toward apex. Head rather distinctly narrower than the pro-

thorax, very finely, not distinctly punctate; antennal prominences feeble, the

epistomal suture scarcely visible, not at all impressed ; vertex rather convex,

not tuberculate; median fovea obsolete ; antenne rather long; second joint

nearly one-half longer than the third, three to eight gradually decreasing in

length and increasing in width, the latter obtrapezoidal, one-half wider than

long, ninth and tenth similar, slightly wider, but not shorter than the ninth,

the eleventh orbicular, scarcely longer than wide, the antenne viewed upon

the compressed side. Prothorar nearly one-third wider than long; sides par-

allel and strongly arcuate, slightly convergent and straighter in basal third,

the basal angles very obtuse, not at all rounded and minutely though notice-

ably prominent, lateral entirely obliterated, apical obtuse but not perceptibly

rounded; apex transverse; base feebly arcuate; basal and lateral beaded

margins distinct; disk finely, densely and somewhat indistinctly punctate, the

median groove fine, impressed, obliterated near base and apex; pubescence

scarcely visible. lytra large, quadrate, slightly dilated behind, where they

are nearly one-half wider than the prothorax, fully three-fourths longer than

the latter; sides feebly arcuate toward apex ; humeri right, narrowly rounded ;

disk finely, rather deeply and very densely punctate, the punctures separated

by from one and one-half to two times their own diameters; pubescence fine,

the elytra, fully one-third wider than the prothorax, finely, sparsely punctate ;

punctures denser along the apices of the segments; under surface densely,

strongly punctate, densely pubescent. Length 4.5 mm.

California (Mendocino Co.).

The hypomera are not impressed along the lateral edges; they

are one-half as wide as the distance thence to the coxe; the coxal

fissures are very long and widely open. The mentum is large and

perfectly flat, finely, densely granulose and dull, the hypoglottis

apparently rudimentary. The prosternal sutures are distinct.

The elytra are sometimes pale, indefinitely clouded toward the

suture. ‘Two specimens are decidedly more slender. This is a very

distinct species, to be placed near diagonalis; the latter resembles

it greatly in form, but has the surface of the head and pronotum

much more shining, and the basal angles of the prothorax obtuse,

narrowly but distinctly rounded, and not at all prominent. From

longipennis it differs in its denser pronotal punctuation; this part

in that species is, according to Mannerheim, “ parce punctato.”

B. honestus n. sp.—Slightly robust, subparallel, black; elytra, legs

and antenne throughout testaceous, the first very broadly and indefinitely

clouded toward the suture: head and pronotum strongly shining, rather

coarsely and strongly reticulate ; abdomen reticulate, polished, the retal lines

fine throughout. Head rather convex, slightly narrower than the prothorax,

not tubercnlate; median fovea very small and feeble, shining, with a few

rather large and distinct widely-dispersed punctures ; antennal tuberculations

moderate, smooth; suture very fine but distinct; antenne rather slender ;

second joint quite robust, nearly as long as the next two, third scarcely one-

half longer than the fourth, fourth and fifth subequal, sixth slightly shorter,

feebly transverse, six to ten very evenly but rapidly wider, the tenth nearly

one-half wider than long, eleventh slightly shorter than the two preceding.

Prothorax as wide as the base of the elytra, one-third wider than long; sides

in anterior two-thirds parallel and nearly straight, then convergent and feebly

arcuate, feebly sinuate for a short distance before the basal angles, which are

very obtuse, slightly rounded and not distinctly prominent; lateral angles

very broadly rounded and not distinct, apical right, very narrowly rounded ;

apex two-fifths wider than the base, just visibly arcuate, the latter truncate ;

disk not very coarsely punctate, the punctures very deep and distinctly defined,

sparsely and somewhat unevenly distributed; pubescence fine, sparse and

inconspicuous, the median groove rather coarse, deep and distinct. Elytra

scarcely as long as wide, just visibly wider and about two-fifths longer than

the prothorax; sides feebly divergent, nearly straight; surface feebly im-

pressed near the base and suture, rather finely and not very densely punctate,

the punctures separated by about twice their own diameters; pubescence

moderate in length, fine, rather sparse. Abdomen just visibly narrower than

the elytra, rather more coarsely and densely punctate than usual, beneath

rufo-piceous, slightly more densely but rather finely punctate. Length 3.3 mm.

New York (Catskill Mts.). Mr. H. H. Smith.

The hypomera are narrow, distinctly less than one-half as wide

as the intervening coxal distance, and are strongly and narrowly

concave throughout the length, the sutures almost completely obso-

lete, the coxal fissures rather long, widely open, the prosternal sur-

face immediately before them transversely impressed. The mentum

is shining, coarsely reticulate and broadly, strongly impressed in

the middle toward base, the hypoglottis membranous, and nearly

one-fourth as long as the entire mentum.

The prosternal sutures being effaced, with the coxal fissures

widely open, constitute of this very distinct species, one of the

bonds uniting the cordatus and annularis groups of LeConte.

Although the sutures are obsolete, it is easy to perceive the extent

of the hypomera, as the reticulation of the surface is longitudinal

on these parts, and without definite arrangement elsewhere.

pale, whitish, translucent, indefinitely clouded with piceous toward suture

and at the base; legs piceous, tibie and tarsi flavate; antenne flavate, pice-

ous toward apex ; integuments polished throughout, head and prothorax very

finely reticulate, the reticulations on the latter tending to a transverse arrange-

ment ; abdomen more coarsely reticulate, the lines very fine. Head distinctly

narrower than the prothorax, very convex, neither tuberculate nor foveate,

rather finely, distinctly and sparsely punctate; antennal tuberculations ex-

tremely small and feeble; epistomal suture very fine, feeble, not impressed ;

anterior angles of the epistoma very minutely but acutely and distinctly tuber-

culate; antenne rather short, gradually and very strongly incrassate; second

joint robust, longer than the rext two together; three to six small, sixth

rounded into the base, without lateral or basal angles; base subtransverse in

the middle; apex broadly evenly and just visibly arcuate; apical angles right

and narrowly but distinctly rounded; disk rather strongly, evenly, trans-

versely convex, very finely, evenly and sparsely punctate ; median groove very

fine but distinct, not quite attaining the apex. Flytra quadrate, about two-

thirds longer than the prothorax; sides nearly parallel and straight; outer

very short, twice as wide as long, shining but coarsely confusedly

reticulate, broadly, feebly emarginate throughout the width at apex,

with a narrow impressed transverse groove just behind and along

the apical margin, and a small deep abrupt impression in the middle

at the base, elsewhere convex and slightly tumid.

The description is taken from the male, the eighth segment having

the usual acute incisure; it is very closely allied to basalis Lec , but

differs in its smaller size, more transverse and more sparsely punc-

tate prothorax, in which the anterior angles are less prominent, and

its shorter, more coarsely and much more feebly punctate elytra, in

which the exterior apical angles are more broadly rounded. In

basalis the mentum is truncate at apex, feebly impressed in the

centre, the surface on each side of the impression forming a rounded

tumid elevation. It is totally devoid of the small round fovea near

the base, which is so marked in ignavus.

B. misellus n. sp.—Rather slender, black; elytra very pale, whitish,

the basal third piceous-brown, the same tint extending broadly along the

middle nearly to the apex ; legs and antennz very pale, the latter infuscate ;

femora darker; integuments polished, except the elytra reticulate, the abdo-

men coarsely so, the lines very fine, the pronotum more finely so, with the

reticulations tending to a transverse arrangement. Head rather distinctly

narrower than the prothorax, strongly convex, neither tuberculate nor foveate,

rather finely but distinctly and sparsely punctate; antennal prominences very

small and extremely feeble; suture tine, not impressed; eyes moderate, very

coarsely faceted, not very prominent; antenne short, robust, gradually and

strongly incrassate, rather strongly compressed ; scape as long as the next six

joints combined ; second joint much longer than the next two, all the joints

after the third transverse, successively more strongly so, compactly placed, the

eleventh short, very broad, not as long as wide, very obtuse. Prothorax nearly

as wide as the base of the elytra, nearly two-fifths wider than long; sides in

apical three-fourths parallel and nearly straight, then abruptly, broadly

rounded into the base without lateral or basal angles; base transverse; apex

truncate, the apical angles acute and slightly anteriorly prominent, feebly

rounded externally; disk transversely, rather strongly convex, very finely

though distinctly, sparsely punctate, the median groove very fine, rather feebly

impressed and not quite attaining the apex. £/ytra slightly longer than wide,

two-fifths wider and fully four-fifths longer than the prothorax; sides just

interior extremely narrowly so; surface feebly impressed near the suture

Texas (Galveston).

The hypomera are feebly impressed along the sides and are rather

wide, the sutures obliterated, the coxal fissures short, almost com-

pletely closed. The mentum is short, fully twice as wide as long,

broadly, feebly emarginate at apex throughout the width, deeply

and coarsely foveate in the middle near the base, the surface dis-

tinctly tumid on either side of the fovea, and having a few coarse

setigerous punctures.

Although to be classed with basalis, this little species, one of the

smallest known in our fauna, is not very closely allied to it. The

elytra are relatively larger and longer, and are much more finely

punctate. The sides of the prothorax are straight in apical three-

fourths, while in basalis the parallel portion of the sides is much

shorter. The series before me exhibits great variation in the extent

of the brownish-piceous tint, this being confined in one specimen to

the basal margin.

B. neglectus n. sp.—Slender, black ; elytra very thin and translucent,

whitish, the suture and base blackish; legs and antenne testaceous, the latter,

infuscate, the femora darker; head and pronotum very finely, densely and

evenly granulato-reticulate, rather feebly shining ; abdomen polished, coarsely

reticulate, the lines fine. Head much narrower than the prothorax, convex,

neither foveate nor tuberculate, finely, rather feebly and sparsely punctate,

the median portions impunctate ; antennal prominences very small and feeble ;

eyes moderate; epistomal suture fine; epistoma with a fine distinct tubercle

on the apical edge near each anterior angle; antennze moderate, rather strongly

compressed, gradually and strongly inerassate; second joint slightly longer

than the next two together, fifth quadrate, rather longer than either the fourth

or sixth, six to ten wider than long, the latter by three-fourths its length,

eleventh very slightly wider than long, very obtuse ; joints throughout not very

compactly joined. Prothorax nearly as wide as the base of the elytra, two-fifths

wider than long; sides in anterior three-fourths parallel and straight, then

very strongly convergent and broadly, feebly but distinctly sinuate to the

basal angles, which are obtuse and rounded but rather distinct, lateral more

broadly rounded and less distinct, apical right, very narrowly rounded, not at

all prominent ; base and apex transversely truncate; disk transversely, mode-

rately convex, rather finely, feebly and densely punctate; punctures separated

by nearly twice their own widths ; median groove very fine but distinct. Llytra

Rhode Island.

The hypomera are very wide, with the sides parallel, flat but

depressed far below the lateral edges, so that the latter are very —

acute and prominent; the coxal fissures are extremely short and

appear to be very narrowly open, the hypomeral edge being be-

neath the prosternal or anterior edge. The mentum is nearly flat,

the subbasal median impression being somewhat feeble.

This species belongs in the neighborhood of basalis, but differs in

the form of the prothorax and sinuation of the convergent portion

of the sides, and in its rather distinct basal angles; the elytra are

more finely and densely punctate and the size considerably larger.

B. turbulentus n. sp.—Rather slender, black; elytra very pale, yel-

lowish-white, the basal margin piceous-black ; legs and antenne testaceous,

the femora darker; integuments polished, head and prothorax finely, evenly

and rather strongly reticulate; abdomen coarsely reticulate, with the retal

lines very fine. Head distinctly narrower than the prothorax, convex; eyes

rather large and prominent; surface finely, rather feebly and sparsely punc-

tate, neither foveate nor tuberculate ; antennal prominences small and very

feeble; suture fine, not impressed; epistoma with a fine apical tubercle near

each anterior angle; antennz rather slender, evenly incrassate ; second joint

not very robust, cylindrical, slightly longer than the next two together, fifth

distinctly longer than wide, eighth and ninth similar in form, the latter the

larger, just visibly wider than long, tenth slightly shorter than the ninth, less

than one-half wider than long, eleventh not quite as wide as the tenth, dis-

tinctly elongate, gradually pointed, as long as the seventh and eighth together.

Florida. Mr. E. A. Schwarz.

This species was confounded by LeConte with basalis, from which

it differs in many conspicuous characters, and chiefly in its much

longer, more slender antennz, these in basalis being very short, the

outer joints very strongly transverse and more compactly connected,

the eleventh very short, obtuse and much wider than long, the fifth

wider than long; it also differs in its much more finely and densely

punctate elytra, and in its decidedly greater size. Basalis is quite

uniform in size, the series of six specimens before me offering but

slight variation in this respect, the length being 2.0-2.2 mm., and

not as great even as the minimum length (2.5 mm.) given by Dr.

LeConte in the original description. The present description is

taken from the male, and it has been compared with the same sex

of basalis.

The structure of the under surface of the prothorax is nearly as

in basalis, the coxal fissures being very short and entirely closed.

The mentum is flat, with a large deep impression in the middle near

the base.

NOTE.

In the list of Staphylinide published since the date of the Munich Catalogue,

recently compiled by M. Ant. Duvivier, appears the name Bledius LeContei

Duviv., for B. phytosinus Lec., under the supposition that the latter name was

pre-occupied, but as LeConte’s name was published in 1877, and phytosinus

Fauvel not until 1878 (1. ¢. p. 101), it is evidently the latter which should

fall and not phytosinus Lec. The name Bledius LeContei has recently been given

by Dr. Sharp to a Mexican species (Biol. Cent.-Amer., Coleop. I, Pt. 2, p. 685).

The Fauvelian species must be considered therefore as still unnamed.

encouraged. The sense of the majority of modern authors seems to favor, or

somewhat resemble Trogophleus in external facies. They are at

once distinguishable, however, by the extremely large, externally

angulate and open anterior coxal cavities, the open portion beyond

the coxe having a large trochantin or plate, which probably serves

the purpose of an operculum; they also differ by having a row

of short rather robust and distinct spinules along the outer edge of

the anterior tibia. The genus is rather closely related to Ancyro-

phorus, the latter being distinguished by the visible scutellum and

rather longer and more conical fourth joint of the maxillary palpi.

The affinity with Oxytelus is much more remote, not only in habi-

tus, but in the special modifications of structure.

The eighth ventral segment of the males, as usual in this portion

of the Oxytelini, is longitudinally divided throughout its length,

forming two distinct parts which overlap. In the present genus

the overlapping edge is parallel to the axis of the body, and the

at least tolerate, the adoption for generic names of any combination of letters

which is moderate in length, easily pronounceable, and which has a Latin

form or habitus so to speak, and although Aploderus may not be as good

Greek as Haploderus, it is at all events a certain definite combination of

letters, having a Latin form, and easily pronounceable, and could not be

altered even by the author himself.

Although generic names are generally taken or derived from the Greek,

they cease to be Greek and become Latin as soon as published over a descrip-

tion, and Aploderus is as good a Latin word as Haploderus, or Bledius, or

Hamletia. The only reason for aitering a name once published is because of a

typographical error which may either delatinize it, or render it unpronounce-

able.

If generic names be not considered as Latin simply and solely, we are

continually guilty of a ‘‘ barbarism’’ of the worst kind—the modification of a

Greek word by a Latin adjective. It being granted therefore that generic

words are Latin and not Greek, it follows that the gender of specific names

should depend upon the énding of the generic name in its Latin sense, 7. e.,

words ending in a, is, and e are feminine, e.g. Tyloderma crea and not wreun.

Unfortunately there are many words used for genera which are perfectly

Greek in form and not Latin; in these cases the only course to pursue is to

give to the specific names genders which coincide with the Latin equivalent,

e.g-, Medon fusculum and not fusculus.

The reason given by LeConte for the suppression of Aploderus and the sub-

stitution therefor of Phlasonweus Erichs., is not, in the opinion of the writer,

a valid one. As long as a certain definite described species is stated by an

author to be the type of a genus, the genus must be considered established,

even though not described.

apex is therefore never deeply angularly incised, as would be the

case when the two edges are oblique, as in Bledius.

In the table and descriptions given below, the specific characters

throughout are drawn from the male only.

The species belonging to our fauna, although as far as known

only five in number, are easily divisible into two distinct groups as

is by far the most remarkable species of this section of the genus.

There are but two specimens known, and the male above described

I owe to the kindness of Mr. C. H. Roberts, of New York.

California (Mendocino, Santa Clara and Monterey Cos.).

The specimens before me consist of a single representative from

each of the above localities—one male and two females. The

species differs from annectens, not only in the characters given in

the table, but in its shorter and rather more coarsely punctate elytra,

and in the sexual characters of the female.

Coleopterological Notices. re

In the male type above described, there is a stout spinose seta at

the posterior extremity of the pubescent area of the sixth segment ;

I cannot determine whether this is accidental or not.’

convergent and nearly straight to the apex and base; basal angles distinctly

rounded, apical nearly right and just visibly rounded, not anteriorly promi-

nent; disk broadly, rather feebly, somewhat indefinitely and arcuately im-

pressed on each side of the rather narrow median impunctate line, the latter

wider near the apex ; punctures moderate, somewhat dense in the impressed

areas. Elytra one-third wider than, and nearly twice as long as the prothorax,

quadrate, depressed, broadly impressed in the middle at base, rather finely

distinctly and densely punctate. Abdomen distinctly narrower than the elytra;

sides straight and parallel.

Male.—Sixth segment normal, without trace of denser pubescence in the

middle ; seventh extremely broadly and feebly emarginate at apex, the middle

of the emargination just visibly produced and arcuate; eighth not impressed.

Female.—Seventh segment longer, broadly rounded at apex, the middle of

the apex with a very feeble sinuation, the margin of the sinuation lined with

a fringe of short, porrected, semi-membranous or gelatinous hairs; eighth

impressed.

Length 3.5 mm.

California (Sonoma Co.).

A wider, more depressed species than the preceding, and appa-

rently somewhat rare. The series before me consists of five speci-

mens, all taken at Fisk’s Mill on the seacoast.

1 Since writing this paragraph I have received one other male example from

Alameda Co, The spine is very distinct and in the same position, but instead

of a single spine, there is here a closely condensed clump of five or six stiff

sete. The appearance of a single stiff spine in the original type is probably

due to the complete agglutination of these sete. The head in the Alameda

male is, however, quite distinctly narrower, and this particular specimen may

possibly be less fully developed.

78 Coleopterological Notices.

THINOBIUS Kies.

This genus, although allied somewhat to Trogophleus, differs in

three very important structural characters, viz: the visible scutel-

lum, broadly rounded inner apical angles of the elytra, and antennal

structure, the fourth and sixth joints of the latter being invariably

smaller than the fifth and seventh. These differential characters are

very constant throughout our species, and there are no others which

I have observed of sufficient importance to warrant the creation of

a new genus. There are, however, certain characters possibly of

subgeneric value, which should at least be noted.

In group I, the pubescence of the elytra is of dual composition.

The very densely placed punctures bear, each, a very minute recum~

bent and scarcely visible seta, sometimes quite robust, and which

constitutes the principal part of the vestiture, but, in addition, there

is a system of longer erect and much more sparsely distributed hairs.

In the other two groups here indicated, there is no sign of this

complexity, and the pubescence is uniform throughout, consisting

of fine erect or suberect hairs, all of equal length. It should also

be stated that in groups I and IT, the sixth abdominal segment is

equal in length to the fifth, while in group ITT it is very much longer.

The European species are divided by Rey into sections which are

considered of generic value. The species here noted under group I,

seem to be entirely congeneric with the true Thinobius of Rey

(Hist. Nat. Col. Fr., Oxyt.), but the Thinophilus of that author is

almost certainly not represented in our fauna, at least there is no

species known to us at present, which possesses the cephalic structure

indicated as a prominent character of that genus (/.c. Plate VI),

and should our groups be considered of subgeneric value, as they

might with possible propriety in a general monograph, they must

receive new names.

The species are probably numerous, but owing to their very

minute size they have been almost totally neglected by our collec-

tors. Those at present known to me may be identified by the fol-

lowing characters :—

Antenne moderate in length, scarcely ever much longer than the head and

California (Oak Grove 1). Mr. G. R. Crotch. Cab. LeConte.

In the type-specimen there is not the slightest trace of an im-

pressed dorsal channel on the pronotum, and the record of one by

LeConte is an inadvertence. The elytra are distinctly paler, rufes-

cent, and practically uniform throughout the surface, the duskiness

of the base and margins spoken of in the original description being

not clearly evident. This is a very distinct species.

New York (Coney Island). Cab. LeConte.

The paler color, larger, relatively longer prothorax, and decidedly

shorter elytra, will serve to separate this species from any other of

the present section of the genus. The antenne are just perceptibly

darker toward tip, and the abdominal punctuation is quite coarse,

New York (near the city 1). Mr. W. Jiilich.

This species, the largest of this section of the genus, approaches

very near to flavicornis in general form, especially in its compara-

tively short elytra and large unimpressed prothorax ; it differs in

its much larger size, in its longer abdominal segments, in color, and

in its much more coarsely granulose and less abbreviated elytra.

In flavicornis the elytra together are very distinctly wider than

long, while in the present species they are quadrate.

California. Cab. LeConte.

A very distinct species, easily distinguishable from any other of

this section by its more robust form, unimpressed pronotum, broadly

emarginate apex of the prothorax, the head, prothorax and elytra

increasing in width in an almost uniform ratio, by the distinctly

arcuate sides of the elytra, the longer, more aberrant antenne, and

many other characters. The measurements of length given by

LeConte in his descriptions of the species of this genus are

decidedly too small.

which is broadly feebly arcuate ; apex broadly, very feebly emarginate, the

apical angles slightly advanced and very narrowly rounded; disk not at all

impressed, feebly convex, very minutely and densely punctate throughout.

California (Duncan’s Mills, Sonoma Co. 2).

May be distinguished from pygmeus by its larger size, longer,

relatively narrower prothorax, with the apical angles more advanced,

and by the entire absence of any distinct pronotal impressions,

Michigan (Detroit 1). Cab. LeConte.

This species bears considerable resemblance to hesperius, but

may be distinguished by its more robust form, larger, wider pro-

thorax, and relatively shorter elytra. In the type, the abdomen is

drawn up so as to be very short, and the length given is therefore

less than the normal one for the species; the length given by

LeConte (0 5 mm ) is not correct.

T. hesperius un. sp.—Slender, piceo-castaneous; legs and antenne

throughout same; integuments dull and dense. Head fully as long as wide,

rather feebly, evenly convex, very densely granulato-punctate ; prominences

moderate in size, feeble; eyes large, feebly convex, very coarsely faceted, the

tempora not quite as prominent, feebly arcuate and scarcely more than one-

half as long; antenne equal in length to the head and prothorax, moderately

robust, distinctly clavate, second joint oval, twice as long as wide, as long as

the next two together, third as wide as long, fourth and sixth equal, smallest,

distinctly transverse, fifth subequal to the third, outer joints feebly transverse,

eleventh ovoidal, pointed, two-fifths longer than wide. Prothorax very slightly

wider than the head, five-sixths wider than long; sides parallel anteriorly and

distinctly arcuate; base broadly arcuate, coarctate with the sides through the

very broadly rounded basal angles ; apex broadly, feebly arcuate ; apical angles

slightly obtuse, not distinctly rounded ; disk feebly, evenly convex, punctate

like the head, with two small feeble impressions at the base, trisecting the

twice as long; humeri right and very narrowly rounded; surface feebly

convex, extremely densely and finely punctato-granulose, the short appressed

pubescence correspondingly dense, and the longer erect hairs somewhat dense,

very small and not easily seen. Abdomen very slightly narrower than the

elytra and subequal in length, feebly narrowed toward tip; border moderate

in width and depth ; surface feebly convex, more coarsely punctato-reticulate

and rather more shining, the pubescence coarser, as usual. Length 0.8 mm.

California (Fort Yuma 3).

This species may be distinguished by its slender form, piceous-

black antennz, short prothorax, and long elytra.

T. pygmezeus np. sp.—Rather slender and depressed, black throughout ;

legs and antenne same; integuments rather dull. Head fully as long as wide

and distinctly longer than the prothorax, very feebly, evenly convex, very

minutely, densely punctate; tuberculations very feeble ; transverse epistomal

suture very distinct; eyes large, feebly convex, the tempora nearly as promi-

nent, very feebly arcuate and nearly two-thirds as long as the eye; antennz

just visibly longer than the head and prothorax, feebly clavate, second joint

slightly less than twice as long as wide, nearly as long as the next two

together, the third very much longer than the fourth which is slightly trans-

verse, subequal to the sixth, the fifth larger and very slightly wider than

long, eleventh one-half longer than wide, ovoidal, abruptly pointed. Pro-

thorax slightly wider than the head, very slightly less than twice as wide as

long ; sides parallel and strongly arcuate ; basal angles very broadly rounded,

the base feebly arcuate; apex truncate, the apical angles slightly obtuse and

scarcely at all rounded, scarcely perceptibly advanced ; disk broadly, feebly

convex, extremely minutely and densely punctate throughout, and broadly

strongly impressed on each side at the base, the impressions trisecting the

width. lytra slightly wider than the prothorax, and about twice as long,

parallel, very minutely, densely punctate and pubescent, the longer suberect

hairs very short, somewhat dense and not very distinct. Abdomen slightly

narrower than the elytra, slightly narrowed toward tip, short; border rather

thick, flat and shallow, the surface transversely convex, more coarsely,

sparsely punctate, and slightly shining, especially the sixth segment. Legs

moderate. Length 1.0 mm.

Nevada (Reno 1).

The abdomen with its somewhat convex surface, and very shallow

and rather wide border, contrasts greatly with the same part as

seen in sonome, but the structure of this part seems to vary con-

siderably within specific limits, even in the mature state.

The three species last described are more closely allied than usual,

and, although easily distinguishable in nature by peculiarities of

form, size and sculpture, are not so satisfactorily differentiated by

description.

The following group of three species is very distinct in the long

slender antenne, with all the joints elongate, and may be further

identified by the abdomen rather strongly narrowed from base to

apex, by the large subrectangular prothorax, with the disk perfectly

even and free from impressions, by the slightly sparser, finer punc-

tures, with the surface correspondingly more shining, and by the

decidedly larger size.

I have not been able to examine this species in nature, and the

characters given in the table were taken from the original descrip-

tion of M. Fauvel.

T. pallidus n. sp.—Rather slender and fusiform, feebly convex, pale

brown ; abdomen piceous ; legs and antenne pale flavate ; integuments slightly

shining. Head about as long as wide, rapidly narrowed and triangular in

front of the eyes; sides in basal half parallel; surface subdepressed, very

minutely punctato-reticulate, finely pubescent ; eyes moderate, rather convex,

very coarsely faceted; antennz much longer than the head and prothorax,

very slender, scarcely visibly incrassate, all the joints much longer than

wide, second shorter than the next two, fourth and sixth slightly shorter than

the third and fifth, and very slightly more slender, tenth nearly one-half

longer than wide, eleventh slender, cylindrical, abruptly pointed at apex,

nearly three times as long as wide. Prothorax slightly though distinctly wider

than the head, about one-sixth wider than long; base and apex subequal, very

feebly arcuate; sides parallel, feebly arcuate; apical angles narrowly, basal

more broadly rounded ; disk broadly, feebly convex, more strongly so near the

margins, even, without trace of impressions, more strongly shining, subaluta-

ceous, very minutely and excessively feebly punctate. /ytra about one-fourth

wider and two-fifths longer than the prothorax, parallel, subquadrate ; sides

nearly straight; surface very feebly convex, alutaceous, excessively minutely

punctate, the punctures smaller but stronger than those of the prothorax, not

in mutual contact. Abdomen narrowed toward apex, very slightly narrower

than the elytra; segments rather long; border strong, not very deep; surface

strongly alutaceous, reticulate in broken transverse wavy lines, the interspaces

dull. Length 1.2 mm.

Texas (Austin 2).

The pubescence of the anterior portion is very fine and dense ;

it is suberect, and is not intermingled with longer hairs as in the

preceding section. It belongs near antennarius of Fauvel, but is a

much smaller species.

wide. Prothorax rather more than one-fourth wider than the head, one-sixth

wider than long; base scarcely perceptibly narrower than the apex, both feebly

arcuate; sides nearly parallel, feebly arcuate; apical angles narrowly but

California (Sonoma, San Mateo and Santa Clara Cos. 8).

This species seems to vary slightly in the relative proportion of

its parts, but I can perceive no well-defined limits of a specific

nature. It is very distinct from pallidus in its larger size, black

color, smaller head, finer, stronger abdominal sculpture, and several

other characters.

in the basal half, and more narrowly so in the anterior half, the edge being

explanate or very feebly reflexed. lytra slightly longer than wide, one-sixth

wider and four-fifths longer than the prothorax ; sides parallel and straight ;

Texas (Austin 1).

A remarkably distinct species, decidedly aberrant in the strong and

complex impressions of the pronotum, and unusually robust antenne.

The punctuation is very much sparser than in any other species

known to me.

out lateral impressions. £/ytra one-third wider than the prothorax, distinctly

the apex for one-fifth the length perfectly smooth and polished ; surface feebly

Length 1.6 mm.

California (Mendocino, Sonoma and Marin Cos. 11).

The pubescence in this well-marked species is not very dense, and

is somewhat longer than usual. The anterior legs throughout,

together with the cox, are pale flavate, the posterior piceous, the

posterior tibize having, at the middle of the exterior edge, a long

erect seta, which seems to be a constant generic character, but

becoming here more than usually pronounced. It is gregarious on

the under surface of chips and stones near running water, and its

motions are extremely slow, differing greatly from the normal forms,

as for instance hesperius, which are never gregarious, and which

move much more rapidly over the sand and adobe mud of the river

bank. Similar differences of habit are well known in the genus

Trogophleus.

PHALACRID.

With the exception of a few more or less isolated descriptions,

the representatives of this family have of late years been greatly

neglected by systematists. The study of the European species has,

however, been recently resumed by Tournier and Flach, and the

description of several interesting new genera by Dr. Sharp in the

Biologia Centrali-Americana, has served to revive a still more

general interest. In the following pages I have attempted to per-

form a corresponding service for the North American species."

The family seems to be more especially characteristic of the

American, than of the European fauna, for it is here that it reaches

its greatest development, not only in the number and variety of its

species, but more noticeably in the unexpected number of distinct

and highly specialized generic groups. Although to a superficial

view presenting a very monotonous and little varied appearance,

I have found the study of the American species a highly interesting

one, the various genera being quite abruptly limited, and charac-

terized by an unusual paucity of intergrading forms.

1 Olibrus piceus Boh., mentioned by Gemm. and Harold (Cat. Col. p. 801) as

described from California, cannot be identified, and, as the name is pre-occu-

pied, should be dropped from our lists. Phalacrus difformis Lec. (Agass. L.

Sup. 222) is an Agathidium. Litochrus brunnipennis Maun. is a Choleva.

90 Coleopterological Notices.

In the general classification of the genera I have departed from

the original Erichsonian system, based upon the relative length of

the anterior and posterior tarsi and visibility of the terminal spurs,

and have taken as the most important characters in the primary

grouping, the structure of the eye and tibial spurs, the mode of

antennal insertion, and the size of the scutellum. In the Olibri

the point of antennal insertion is exposed from above, the large

irregular pit or fovea in front of the under part of the eye being

very shallow, because of the deep sinuation of the sides of the

epistoma. In all the genera of this group there is visible, just

above the point of insertion and immediately under the extreme

.upper edge of the epistoma, a round flattened chitinous tubercle,

apparently entirely filling a deep fovea; this is very constant in all

the genera, but its significance cannot be determined.

The variation in the form of the trophi in passing from one genus

to another, appears to be of so little importance in comparison to

the sternal and tarsal structure, that but slight use has been made

of these parts, and they have been totally disregarded in the scheme

of arrangement here proposed. They are, however, of somewhat

greater moment in the Litochride genera, as will appear below.

In the following table I have included all the described genera,

indicating those which do not occur within the faunal limits of the

United States by an asterisk! The genus Augasmus Mots. is

said by Tournier to be identical with Phalacrus, and the recently

described Olibrosoma of Tournier, seems to be so aberrant in its

five-jointed antennal club, that I think it would be better to exclude

it from the family as at present organized; it may possibly find a

more fitting place in the Silphide. With these exceptions, there-

fore, the family is found to consist of three groups of genera which

may be defined as follows :—

Eyes of dual structure, the upper portion finely faceted, the lower coarsely

so; spurs of posterior tibiw strongly dilated. ‘

Antenne exposed at base, the epistoma projecting and trapezoidal ; seutel-

lum small or moderate ; elytra striate throughout the width.......ToLyeut

Fyes normal, coarsely faceted throughout; spurs of posterior tibie not at all

dilated.

The antenne in this genus are unusually short and robust, the

two basal joints of the club strongly transverse. The prosternal

process is rather wide, gradually inflexed at apex, and margined

throughout the sides and apex with a fine strong convex bead;

is not in the least setose, and, in repose, rests against the vertical

portion of the mesosternum. The metasternal process is rather

narrower than in Phalacrus, but similar in form and extent, the

mesosternum forming a fine apical and lateral bead. The mesoster-

num behind the middle acetabula forms a fine bead as in Phalacrus,

The terminal spurs of the posterior tibie are short, although

projecting well beyond the terminal fringe of spinules; they are

very strongly dilated toward base and pointed at apex.

The singular structure of the eyes mentioned in the table, together

with the structure of the tibial spurs, isolates Tolyphus widely from

the entire remainder of the family, and constitutes of it a group

equivalent to either the Phalacri or Olibri. The first of these

characters, neither of which has apparently been before noticed, is

of exceedingly rare occurrence in the Coleoptera; the second is

often seen as a modification of the anterior spurs in the Harpalini.

The observations above noted were made upon 7. granulatus

Guér, from Spain. No species has yet occurred outside of the

Mediterranean province of the palearctic fauna.

PHALACRUS Payk.

The general characters distinguishing this genus from the others

are fully laid down in systematic works, and are stated in a less

extended form in the preceding table.

The species do not appear to be very numerous, and among the

sixty-seven specimens before me, I am unable to distinguish more

than eight, which is considerably less than the eighteen described

by Tournier (L’Ent. Gen. 1889, pp. 7-10), as belonging to the

European fauna. The species are more closely allied and indefinite

than in any other genus of the family. I have not noticed any

distinct sexual modification in the male; the middle of the anterior

margin of the epistoma is, however, in some forms broadly arcuate

and coarctate with the sides and in others more or less truncate,

and these differences are said by both Tournier and Flach to be

sexual in origin. I have not attempted to verify this, and have

simply mentioned the form of the apical margin when noticed

during description.

The punctures of the head mentioned by Tournier, are present in

all our species, but I have not been able to employ them in separat-

ing or characterizing the species, as they appear to vary in relative

position in different individuals. These little fovea to the number

of four, are situated along the inner margin of the eye, and there is

also another near the anterior margin of the epistoma, and remote

from the eye; they are not setigerous as far as can be observed with

the highest working powers.

The sculpture of the elytra is moderately constant, but the im-

pressed lines lying parallel to and near, but not including the series

of punctures, are more or less variable in distinctness, and do not

seem to form a specific character of very great importance.

On each elytron in some if not all the species there are certain

short stiff and erect sete, which do not appear to have been previ-

ously noticed, and which in simples are disposed as follows :—

A row of very closely-placed excessively minute sete along .the

under surface of the acute lateral edge, projecting downward.

A row of more distant, longer and coarser sete, very close to the

minute bead forming the lateral edge, or just within its outer limit.

Finally, on the disk of each elytron, five rows of excessively

minute stiff sete which are extremely widely spaced, and more

evident toward apex. The fifth row from the suture contains six

94 Coleopterological Notices.

or seven sete and extends nearly to the base, the fourth row four

sete, extending to about one-fourth the length from the base, the

third row about three sete, extending slightly beyond the middle,

the second row two, extending nearly to the middle, the first row

being between the sutural and discal striz and containing two to

four sete.

The sete are more widely spaced in the rows toward the suture,

except in the first row where they become slightly less distant.

The setigerous punctures may or may not coincide with the punc-

tures of the series, and do not differ greatly from them in form,

being merely a little more pronounced. In some species they are

not visible at all, but as far as I have been able to observe the

marginal line of larger, more closely placed sete never becomes

obsolete. These are entirely distinct from the excessively minute

fine recumbent hairs, borne by the ordinary punctures, and no

doubt serve quite a different purpose.

In the following table only those characters are employed which

appear to be of decided importance ; they relate to the sternal, tarsal

and antennal structure, and elytral sculpture, and weight should

perhaps be assigned to them in the order named :—

Metasternal process not extending beyond the middle coxe, truncate at apex.

California (Sonoma and Monterey Cos.).

The metasternum projects between the middle coxe to the ante-

rior limit of the latter; it is broad and subtruncate at apex, between

three and four times as wide as the narrowest part of the prosternal

process, and the mesosternum forms a fine bead in the middle por-

tions of the apex, which becomes much more evident at the sides.

The species resembles penicillatus very closely in sculpture and

coloration, but is smaller, the largest specimens being equal in size

to the smallest of that species; its form is more narrowly and evenly

elliptical, and the structure of the meso-intercoxal parts quite dif-

ferent. In penicillatus the metasternal process extending beyond

the anterior limit of the middle cox, the mesosternum is excavated

under the overreaching visible portions, while in the present species

the mesosternum, excepting the portion forming the very fine ter-

minal bead of the metasternum, forms a very feebly concave per-

pendicular surface.

convex ; eyes moderate, their surface perfectly continuous in convexity with

the front, and their lateral margin coarctate with the anterior margin of the

head, the latter perfectly evenly arcuate throughout in circular segment; sur-

face finely and somewhat sparsely punctate; antenne moderate, funicle very

wide as long; base transverse, very feebly broadly sinuate at each side of the

scutellum ; bead very feeble and entirely obsolete in lateral third ; sides evenly

arcuate; disk very finely and rather sparsely punctate. Scutellum large,

nearly twice as wide as long; sides feebly arcuate; apex narrowly rounded ;

surface very finely, feebly punctate except toward the margins. Elytra about

three times as long as the prothorax, abruptly rounded behind; sutural stria

very fine, forming a narrow sutural bead, continuous along the scutellum with

the transverse basal stria, the single discal stria fine but distinct, joining the

sutural at the apex, and becoming obsolete at one-fifth the length from the

base; disk highly polished, without reticulation, having equidistant approxi-

mate rows of fine rounded feeble punctures, the alternate rows being slightly

better defined, the punctures becoming obsolete toward base, and scarcely per-

ceptibly larger near the sides and apex. Abdomen clothed rather sparsely with

stiff semi-erect hairs. Legs robust; middle and hind femora with a row of

stiff hairs along the posterior lower edge, which become longer near the apex ;

anterior femora without trace of such hairs, posterior clothed on the lower

surface with coarse yellowish hair; terminal spinules of posterior tibiz short,

even, concealing the spurs, the corresponding tarsi short, with the first joint

about one-half as long as the second. Length 2.3-3.0 mm.

Southern California; Arizona; New Mexico.

In the type, which is one of the larger specimens from Southern

California, the metasternal process projects well beyond the middle

cox, the apex being broadly arcuate or subtruncate, the mesoster-

num forming a thickened and very strong apical bead; the width

of the portion between the middle cox is three times as great as

the narrowest part of the prosternal process; the latter is impressed.

In other specimens the metasternal process is nearly four times as

wide as the prosternal, more strongly arcuate, and more finely

beaded at apex.

together, club very slender, the eleventh joint distinctly longer than the two

preceding together. Prothorar very minutely sparsely and feebly punctate,

extremely broadly feebly lobed at base; beaded margin evident in the middle.

Arizona (Coolidge).

The metasternal process, as usual, projects beyond the cox and

is strongly rounded at apex, with a fine apical bead; it is about three

times as wide as the prosternal process, the latter moderate in width.

This species very greatly resembles simplex, but differs in its

finer, feebler, sparser and less dilated punctures at the sides of the

elytra, in its still more slender posterior tarsi, and in its decidedly

smaller size. It is represented by two specimens, collected by Mr.

H. F. Wickham.

P. simplex Lec.—Proc. Ac. Phil., 1856, p. 16.—Ovoidal, more pointed

behind, black; legs and antenn piceo-testaceous; upper surface highly

polished. J/ead feebly subtruncate in the middle at apex, feebly convex, very

minutely feebly and sparsely punctate; antenne rather short, the club about

as long as the six preceding joints together, not very robust, the eleventh joint

one-half wider than the ninth and nearly one-half longer than the two preced-

ing together. Prothorax slightly more than twice as wide as long, two-thirds

wider at base than at apex ; basal bead almost completely obsolete ; disk very

minutely, sparsely and feebly punctate. Scutellum large, two-thirds wider

than long, triangular, the sides very feebly arcuate, and the apex just visibly

rounded, the surface extremely finely sparsely and obsoletely punctate. Elytra

about two and one-third times as long as the prothorax, gradually narrowed

behind and acutely rounded at apex, the sutural stria very fine and as usual

continuous along the scutellum, the discal stria fine but distinct, terminating

at one-fifth the length from the base; disk polished, not at all reticulate or

subgranulose, except very obsoletely so near the apex, and in the very vaguely

impressed strie adjacent to the ill-defined rows of punctures, the latter very

fine and feeble except near the sides and apex, where they become abruptly

unusually large, strong and broadly lunate; the vaguely defined impressed

lines are, however, more or less definable nearly to the base. Abdomen covered

sparsely with very coarse hairs, denser toward the middle. Legs moderate ;

posterior tarsi slender, nearly three-fourths as long as the tibiw, the basal

joint not quite one-half as long as the second. Length 1.9-2.5 mm.

specimens of which the original type is one, occasionally entirely

disappear.

There are before me two specimens collected at Luna, New

Mexico, by Mr. Wickham, which appear to belong to this species ;

they are nearly as small as Say7, and notably smaller than any other

specimens of simplex which I have seen. I prefer to attach them

provisionally to simplex, because the punctures at the sides of the

elytra are wide and deeply impressed, as in that species, but they

are not included in the above measurement of length.

P. politus Melsh.—Proc. Ac. Phil., II, p. 102.—Broadly oval, from one-

third to two-fifths longer than wide, black above and beneath; legs and

antenne paler, dark rufo-testaceous ; moderately shining. Head feebly sub-

truncate at apex, very minutely, feebly reticulate in broken wavy lines, finely,

rather sparsely and distinctly punctate; antenne rather slender, club much

shorter than the six preceding joints combined, the last joint about one-third

longer than the two preceding together. Prothorax twice as wide at base as at

apex, and slightly more than twice as wide as long, the basal bead fine and

distinct in middle third; disk excessively minutely and feebly reticulate in

wavy lines, extremely minutely, feebly and rather sparsely punctate. Scutel-

lum acutely ogival, one-half wider than long. Llytra about twice as long as the

prothorax, not narrowed toward apex which is very broadly, evenly rounded ;

sutural stria continuous, very fine; discal fine, distinct, terminating at basal

sixth ; disk without distinct impressed lines, having approximate and nearly

equal rows of fine feeble punctures, which do not become entirely obsolete at

base, and rather abruptly much larger, stronger, partly confused and broadly

lunate at the sides and apex ; surface finely and distinctly reticulate, the reti-

culations extremely minute, and forming imperfectly defined transverse wavy

rows toward base, coarse and more rounded toward sides and apex. Abdomen

finely reticulate, rather coarsely, subasperately punctate, coarsely pubescent.

Tarsi moderately slender, with unusually coarse and prominent tufts of yel-

lowish hair beneath, the posterior two-thirds as long as the tibie, with the first

joint scarcely one-half as long as the second. Length 1.5-2.2 mm.

Pennsylvania; North Carolina; Missouri; Texas.

The metasternal process projects far in advance of the middle

cox, and is strongly rounded at apex, the apical bead rather fine

and not at all dilated laterally, the prosternal process unusually

wide, being at its narrowest part but slightly less than one-half as

wide as the metasternal. '

This species is very common and widely diffused; it does not

appear to vary much except, as usual in this genus, in point of size.

It is the least shining of any of our species except pumilio.

Abdomen sparsely clothed with coarse hair. Legs moderately robust ; terminal

spurs of posterior tibie small, short but distinct and not concealed by the

even and closely-placed row of terminal spinules ; corresponding tarsi rather

slender, nearly three-fourths as long as the tibie, the basal joint two-thirds as

California (San Diego); Arizona.

The metasternal process is of the usual width; it projects slightly

beyond the middle cox, and is strongly rounded at the apex, the

apical bead very fine and not much dilated laterally.

This species is not very closely related to any other, resembling

penicillatus in sternal structure, but differing greatly in size, shape

and sculpture.

P. seriatus Lec.—Proc. Ac. Phil., 1856, p. 15.—Broadly, evenly ellipti-

become larger at the sides, and which disappear only within a very short

distance of the base. Abdomen reticulate in wavy lines, especially near the

sides, coarsely pubescent. Legs robust, posterior tarsi somewhat robust, very

densely, coarsely pubescent beneath, about one-third as long as the tibie.

Kansas—Dr. LeConte; Colorado—Mr. Schwarz. _

The description is taken from one of the Colorado specimens, as

the original type cannot be found.

The metasternal process is rather narrower than usual, projects

far beyond the middle cox, and is strongly rounded throughout at

apex; it is scarcely three times as wide as the narrowest part of the

prosternal process, and the apical bead is rather fine and not dilated

laterally. It is a very distinct species in its strongly marked, ap-

proximate, equal rows of elytral punctures. The type exhibits no

trace of impressed elytral lines.

P. pumiilio Lec.—Proc. Ac. Phil., 1856, p. 16.—Evenly, rather broadly

oval, scarcely one-half longer than wide, black above, piceous beneath ; legs

shorter than the fourth and fifth together. Prothorar very nearly as in

politus. Scutellum ogival, nearly two-thirds wider than long. lytra a little

more than twice as long as the prothorax, not at all narrowed toward apex,

broadly, evenly rounded behind, with reticulation and discal strie nearly

as in politus; having approximate and nearly equal rows of rather small and

distant, and extremely feeble punctures which are, at the sides, much larger,

more confused and broadly lunate; surface with very fine vague impressed

lines, which are continuous nearly to the base. Legs moderately robust, short.

Length 1.4 mm.

Middle Atlantic States.

The condition of the type, which is the only specimen which I

have seen, prevents a description of the abdomen and posterior

tarsi. The metasternal process is very wide, and projects far

beyond the middle cox, the apex strongly rounded, the apical bead

very strong and rather flat, not dilated laterally.

Pumilio greatly resembles a very small specimen of politus,

almost exactly so in sculpture; it is, however, very distinct in

several important points of structure, and notably in the antenne,

in which the third joint in politus is fully as long as the next two

together, also in sternal structure, the prosternal process here being

much narrower and not over a third as wide as the metasternal.

The punctures of the elytral series are, on the upper parts of the

disk, rather more distant and decidedly more feeble than in politus.

It appears to be very rare.

PHALACROPSIS n. gen.

Mentum trapezoidal, truncate at apex. Maxillary palpi with the last joint

slender, subcylindrical, minutely truncate at apex, slightly narrower than the

third, and nearly twice as long. Antenne slender; third joint as long as the

next two together ; club slender, the ninth joint fully as wide as the tenth and

slightly longer, eleventh narrower, elongate-oval, and slightly shorter than the

two preceding. Prosternal process moderate in width, very feebly concave,

inflexed, not ciliate at apex ; metasternal process broad, fully three times as

wide as the prosternal, projecting to the anterior limits of the coxal cavities,

where it is transversely truncate, the truncation very feebly arcuate, the apical

bead very fine in the middle, thickened at the lateral angles, and again fine

along the coxal cavities. Legs short and very robust; spurs of the posterior

tibiz slender, equal, nearly parallel, projecting distinctly beyond the spinose

fimbria ; the corresponding tarsi but very slightly longer than the anterior,

nearly as in Phalacrus, with the basal joint less than one-half as long as the

second. Pronotum without trace of basal bead in the middle. Scutellum

large. Elytra not at all striate, having a very fine sutural bead, the fine stria

being continuous with the basal stria along, and almost touching, the scutel-

lum ; discal stria entirely obsolete.

The single species forming the type of Phalacropsis, is quite

peculiar in form, being decidedly more elongate-oval and just per-

ceptibly more depressed than in the various forms of Phalacrus.

Although remote, it is the nearest ally of Tolyphus in our fauna.

P. dispar Lec.—Bull. U. 8. Geol. Survey, V, No. 3, p. 513.—Castane-

twice as wide as the head, polished, without trace of reticulation, very minutely,

rather sparsely but distinctly punctate; base transverse, feebly sinuate at each

side of the scutellum. Scutellum large, about twice as wide as long, ogival,

very obsoletely finely and sparsely punctate. lytra nearly three times as long

as the prothorax, not narrowed behind, broadly, evenly rounded at apex,

polished but having very indistinct traces of minute wavy reticulation, which

becomes more evident and confused near the sides and apex ; punctures lunate,

arranged in rather poorly-defined distant series, the intervals with more con-

fused punctures which are nearly equal to them in size, rather large but feeble,

much larger, denser and more confused at the sides, where they are very

broadly crescentic. Legs and under surface pale testaceous, sparsely, coarsely

pubescent. Length 3.0 mm.

Colorado (Veta Pass). Mr. Schwarz.

I have only seen one specimen of this remarkable species.

OLIBRUS Erichs.

The genus Olibrus differs from Phalacrus in only two very im-

portant particulars, but in a large number of characters which must

be considered of more or less subsidiary value. The two most

marked differences are found in the mode of antennal insertion, and

in the size of the scutellum. In Phalacrus and its allies with large

scutellum, the antenne are inserted far under the epistoma in very

deeply excavated cavities in front of the eyes, the anterior margin

of the head being arcuate continuously with the eye throughout the

width, while in the genera with small scutellum, the epistomal edge

is deeply sinuate laterally, and the points of antennal insertion more

visible from above. In the structure of the sterna the two genera

are identical. The posterior tarsi and tibial spurs are, however,

slightly longer than in Phalacrus, but I cannot regard this as of

such decisive importance as the two characters mentioned. The

small fovee near the eyes, visible in the genera with large scutellum,

are generally obsolete in the others. From Stilbus this genus differs

much more radically than it does from Phalacrus, in the very im-

portant structure of the mesosternum behind the middle cox.

In two characters Olibrus stands almost alone in the family,

the one relating to the form of the terminal joint of the antenne,

the very strongly constricted terminal process so perfectly developed

here being merely indicated in Phalacrus, and almost entirely obso-

lete in Stilbus, the other relating to the punctures of the elytral

series, which are never transversely crescentiform, but if modified

at all from fine simple points, distinctly attenuate posteriorly ; this

form of elytral punctuation I have not found to exist elsewhere,

except in Olibroporus.’ It is true there are many species of Stilbus

which are perfectly devoid of the peculiar crescentiform punctures,

but in this case the punctures simply disappear and never assume

the elongate form here alluded to.

In the absence of the’ terminal line of robust setiform spinules at

1 There is an undescribed South African species before me, in which the

punctures at the sides become slightly dilated, but although it is apparently

assignable to Olibrus, I am not entirely certain that it really belongs to that

genus.

the apex of the prosternal process, Olibrus again resembles Phala-

crus and differs correspondingly from Stilbus. In fact the resem-

blances of Olibrus to the latter genus must be regarded as in great

part superficial.

Our species are very much less numerous than those of the Euro-

pean fauna, but the very limited number which we possess are more

heterogeneous, and this opinion is strengthened by the characters

assigned to the Central American forms by Dr. Sharp. Our species

are in fact divisible into two groups of subgeneric importance, only

one of which appears to be represented in the European fauna.

The metasternum is polished, not reticulate and not perceptibly

punctate, the process rather short, strongly rounded at apex, the

mesosternum widely visible at the sides of the apex, but reduced to

a fine acutely elevated bead in the middle.

This species has heretofore been considered identical with the

European bicolor, but specimens of the latter sent me by Reitter

and confirmed as to their identity by the tables of Flach, show con-

clusively that it is very distinct. In the true bicolor, the elytra are

reticulate at least as far as the middle, the metasternum is coarsely

and deeply punctate, the form is much more elongate, the size is

larger and the elytral spots more diffused. LeContei seems to

coincide much more closely with the lepidus of M. Tournier’s

recently published table (L’Ent. Gen. I, p. 89), but is probably

distinct, as the European species of this group seem to be uniformly

more slender and attenuate behind, and have a large part of the

elytra distinctly reticulate.

base ; basal bead distinct in the middle; surface extremely sparsely minutely

and feebly punctate. Scutellum wider than long, ogival. Elytra nearly three

times as long as the prothorax ; sutural bead very fine, disappearing at basal

third ; discal striz fine but distinct, almost exactly as in LeContei; surface not

reticulate, having rows of very fine punctures accompanied by the feeblest trace

of fine impressed lines; alternate series more distinct, the intermediate series

of finer punctures almost completely obsolete toward suture. Abdomen minutely

and rather strongly reticulate and alutaceous except as usual along the apices

of the segments, where it is polished, coarsely and rather sparsely pubescent,

and subasperately punctate. Legs nearly as in LeContei. Length 2.2 mm.

New York.

The metasternum is polished, not perceptibly punctate, the few

sparse hairs entirely filling the punctures, the process is broader

than usual, broadly, evenly rounded at apex, projecting but slightly

beyond the middle coxe, the mesosternum being reduced to a very

fine apical bead which is only slightly wider at the extreme sides

of the apex.

The vitte of the elytra are extremely diffused, and in some lights

become almost invisible; the punctures of the elytra are rather

more distinct than in Le Contez, and the form is slightly more elon-

gate-oval and less attenuate behind than in that species.

O. nigricollis Lec.—Trans. Am. Ent. Soc., 1868, p. 50.—Evenly, rather

broadly elliptical, strongly convex, polished; head and pronotum blackish-

piceous ; elytra rufo-testaceous, the lateral margins narrowly, more feebly and

indefinitely, and a broad, more definite and darker sutural, vitta piceous, the

latter gradually attenuate from base to apex; under surface piceous-brown,

the legs and antenne flavate. Head strongly, sparsely punctate; eyes small.

Prothorax more than twice as wide as long; basal lobe very broadly, feebly

arcuate; basal bead fine, flat, strongly marked, obsolete at lateral fourth ;

disk very minutely, sparsely punctate, the punctures rather denser and more

distinct laterally ; marginal bead very fine; apical angles right, very narrowly

rounded. Scutellum two-thirds wider than long ; apex rounded ; sides arcuate.

Elytra about three times as long as the prothorax, not narrowed behind ; apex

very broadly rounded; sides coarctate with those of the prothorax; basal

stria very fine, reflexed along the scutellum and obsolete opposite the apex of

the latter ; sutural bead very fine, attaining the apex of the scutellum; two

discal striz very fine but distinct, the first continuous from the suture at the

apex and obsolete at basal fourth, the second approaching very near the first

at apical sixth or seventh, obsolete at basal third, sometimes also with traves

of an incomplete third discal stria; disk polished, not reticulate except

coarsely and confusedly so at the apex and thence slightly along the sides,

having even distant rows of very minute punctures, the rows not attaining

the base, the punctures coarser and confused near the sides and apex ; inter-

vals with uneven single rows of excessively minute feeble punctures. Meta-

sternum polished, with scarcely perceptible sparse feeble punctures. Length

New Mexico (Las Vegas); Dakota (Bismarck).

Although the elytra are unmistakably vittate in this species, it

cannot be considered a variety of vittatus; its large size, dark head

and prothorax, much broader and more definite pale vitte, coarser,

denser and more rugose punctuation at the sides and apices of the

elytra, and especially the more coarsely punctate head, preclude any

such association.

The original unique type is immature, as there is no trace of the

dark sutural stripe. The measurement given in the original descrip-

tion is too great.

next two combined, club rather robust, scarcely as long as the first three joints

combined, ninth triangular, a little wider than long, tenth trapezoidal, twice

as wide as long and distinctly wider and shorter than the ninth, eleventh as

wide as the tenth, as long as the two preceding, but slightly wider than long,

rather abruptly constricted at apical third forming a very distinct narrowly

rounded apical process. Prothorax at base twice as wide as the head, a little

more than twice as wide as long, slightly lobed and feebly beaded at the middle

of the base, very obsoletely and finely punctate. Scutellum small, a little

wider than long. lytra two and one-half times as long as the prothorax, not

narrowed behind, polished, not reticulate, with a fine transverse basal stria,

reflexed slightly along the scutellum where it becomes obsolete ; sutural bead

wanting near the base, very fine thence to the apex ; discal strize two in num-

ber, the first extending to basal fourth, the second a little beyond the middle,

the first uniting with the suture at the extreme apex, the second vanishing

without attaining the suture at apical fourth or fifth ; disk with distant rather

regular rows of excessively fine feeble punctures, which become slightly more

visible but still in regular series at the sides, almost obsolete at base, the rows

not accompanied by impressed lines, the intervals excessively minutely feebly

and obsoletely punctate in single irregular lines. Abdomen rather distinctly

and subasperately punctate, plentifully but not densely pubescent. Legs

moderate ; posterior tibial spurs slender, rather long, the corresponding tarsi

robust and well marked. Length 2.6 mm.

Kansas; Texas; Pennsylvania; New York.

The punctures of the elytral series are minute points, apparently

absolutely non-setigerous. The metasternal process extends beyond

the coxe, and rests upon the inflexed prosternal process; it is

strongly rounded at apex, very finely beaded throughout, and

around the edges of the middle acetabula; its surface is polished,

with a few excessively minute feeble and widely scattered setigerous

punctures; the sides are slightly divergent from apex to base, at

which latter point it is about three times as wide as the prosternal

process, and as wide as the length of the last antennal joint. There

is sometimes a very short isolated third elytral stria.

The species described by LeConte as striatulus, I believe to be

the same as this, and the above description is taken from the origi-

nal type of strzatulus.

as in pallipes. Prothorax twice as wide at base as at apex, distinctly lobed in

the middle at base, the edge sightly sinuate opposite the scutellum; basal

bead distinct, becoming obsolete at one-fourth the width from the sides ; sur-

face very sparsely, unevenly, feebly punctate, the punctures subelongate.

Scutellum moderate, wider than long, rounded at the sides. lytra three

times as long as the prothorax, strongly, evenly rounded at apex, polished,

without reticulation except very near the apex, not perceptibly so at the

sides ; sutural bead very fine, continuous to within a very short distance of

the scutellum ; first discal stria joining the suture at the apex, vanishing at

less than one-third the length from the base; second distinct, obsolete at one-

third the length from the base and one-fifth or one-sixth the length from the

apex, approaching but not uniting with the first ; basal stria continuous along

the scutellum ; disk with series of very fine feeble evidently elongate punc-

tures, distinctly stronger at the sides, and accompanied by distinctly impressed

lines which are continuous to the base. Abdomen moderately pubescent. Legs

rather robust ; posterior tibial spurs distinct, the corresponding tarsi three-

fourths as long as the tibiw, with the first joint one-half as long as the second.

the process extending beyond the cox, strongly and narrowly

rounded at apex, the mesosternum forming an apical border which

is very fine in the middle but dilated at the sides and rather feebly

declivous, so that it is readily visible in a perpendicular direction

from below; it is moderate in width.

The description is taken from an eastern specimen which is much

larger than the Kansas type, as the latter is in very bad condition.

The species greatly resembles pallipes, but seems to be distinct.

0. neglectus n. sp.—Evenly and not very broadly elliptical, strongly

convex, highly polished, black ; under surface piceous-brown; legs, trophi

shorter and wider than the ninth, much more than twice as wide as long, more

pointed on the anterior side toward the apical angle, eleventh pyriform, slightly

wider than the tenth, as long as the two preceding together. Prothorax of the

usual form, feebly lobed in the middle at base, the lobe evenly, feebly arcuate ;

basal bead distinct, becoming obsolete at one-fourth the width from the sides ;

disk extremely minutely, feebly, sparsely punctate. Scutellum moderate, two-

thirds wider than long, ogival; sides feebly arcuate; apex not rounded. Elytra

two and one-half times as long as the prothorax, rather strongly rounded at

apex, the sutural bead obsolete at nearly one-fourth the length from the base,

excessively fine ; discal strie very fine, the first continuing to within one-eighth

the length of the base and joining the suture just before the apex, the second

obsolete at two-fifths the length from the base and one-fourth from the apex,

at this point approaching very close to, but not joining the first; surface with

traces of very fine impressed lines, polished, but with feeble traces of minute

reticulation, which becomes very evident at the apex and also along the sides ;

punctures of the series excessively fine and feeble, becoming but slightly more

visible at the sides, rather distant in the rows, the intervals punctured in

single series which are almost as regular as the principal series, but composed

of smaller punctures; punctures not elongate and each with a very minute

fine recumbent hair. Abdomen with coarse sparse pubescence. Legs rather

slender ; posterior tibiz slender, spurs distinct, the corresponding tarsi three-

fourths as long as the tibie, with the basal joint scarcely one-half as long as

the second, the latter subequal to the fifth. Length 1.8 mm.

The metasternum is polished and not distinetly punctate, having

fine, very sparse pubescence, the process advancing but slightly

The basal stria of the elytra is very fine and is reflexed along the

scutellum, rather distant from the latter and not extending beyond it.

O. rufipes Lec.—Proc. Ac. Phil., 1856, p. 16.—Rather narrowly oval,

fully three-fourths longer than wide, rather distinctly attenuate behind from

basal fourth of the elytra, polished, piceous-black above, testaceous beneath,

the metasternum and abdomen clouded with piceous; legs and antenne pale

flavo-testaceous. Head finely but rather strongly and distinctly punctate ;

antenne nearly as in vittatus. Prothorar more than twice as wide as long, with

a broad distinct median lobe at base; basal bead distinct except toward the

sides ; surface finely but rather distinctly, sparsely and somewhat unevenly

punctate, the punctures attenuate posteriorly. Scutellum ogival, one-half

wider than long. lytra three times as long as the prothorax ; sutural bead

very fine, becoming obsolete near the base; discal striz fine but distinct, both

becoming obsolete at basal third, the first coincident with the suture at the

extreme apex, the second approaching but not joining the first at apical fourth

or fifth ; having also series of exceedingly minute simple punctures which are

scarcely more distinct at the sides, the series accompanied by fine, feebly im-

pressed lines which almost attain the basal stria; surface with very feeble,

densely crowded, longitudinally aciculate reticulations, which are extremely

minute, more distinct at the sides and especially at the apex, where they

become more rounded and less aciculate. Abdomen sparsely pubescent, alutace-

ous. Legs moderate; posterior tarsi slender, three-fourths as long as the tibie,

with the first joint abont one-third as long as the second. Length 2.0 mm.

Oregon. Cab. LeConte.

The metasternum is polished, although finely reticulate, very

sparsely, finely punctate and pubescent; the process is rather wide,

projecting beyond the cox, with the apex broadly rounded, almost

subtruncate in the middle, the mesosternum not distinct at the sides.

This species differs from the preceding in its broader, more

obtusely rounded metasternal process, which is here about as wide

as the anterior femur; in neglectus it is not much more than two-

thirds as wide.

0. Wickhami n. sp.—Elongate-oval, nearly twice as long as wide,

more or less attenuate from anterior third, black above, piceous beneath;

trophi, antenne, tibie and tarsi paler, rufo-testaceous; shining. Head very

finely, sparsely punctate; antenne moderate in length, rather slender, third

joint as long as the next two together, club of nearly normal form but slightly

less strongly compressed, slightly more parallel and less robust. Prothorax

but slightly more than twice as wide as long; sides less arcuate than usual;

basal lobe broadly arcuate ; basal bead very feeble; surtace polished, not at

all reticulate, extremely minutely, feebly and sparsely punctate. Scutellum

moderate, ogival, nearly twice as wide as long. Elytra three times as long as

the prothorax ; sutural bead very fine, not becoming entirely obsolete at the

base, the single discal stria very close to the suture, distinct, extending to

basal third, coincident with the suture just before the apex: having rows of

excessively minute, feeble, posteriorly attenuated punctures, attended by

finely impressed lines which are continuous to the basal stria; entire surface

covered with a dense system of short, closely crowded, longitudinally aciculate

reticulations, which are strongly marked toward apex and the sides but some-

times very feeble or obsolete on the upper portions. Abdomen polished, with-

out the usual minute reticulation, rather coarsely, asperately punctate, very

coarsely pubescent. Legs normal, not very robust; posterior tarsi slender,

three-fourths as long as the tibizw, with the basal joint about one-third as

long as the second. Length 1.7—-2.4 mm.

Southern California; Arizona; New Mexico.

The metasternum is excessively minutely, sparsely punctate,

reticulate in wavy lines laterally; the process is rather wide, ex-

tending very slightly beyond the coxe, broadly rounded and finely

beaded at apex, the mesosternum very narrowly visible and decliv-

ous at the sides in front of the coxz as usual. The third joint of

the maxillary palpi is distinctly longer than wide, the fourth scarcely

wider, elongate fusiform and nearly twice as long as the third.

In one specimen the discal stria does not quite attain the middle

of the elytra, and in several other respects this species seems to be

very variable. In the five typical representatives obtained by Mr.

G. W. Dunn, in Southern California, or the northern part of Lower

California, the form is generally very slightly narrower than the

majority of a large series taken by Mr. H. F. Wickham, at various

localities in Arizona and New Mexico, and the type has a distinctly

longer development of the metasternal process than can be observed

in the others, this process gradually shortening by insensible degrees,

until in one of the broader forms from New Mexico, the mesosternum

instead of being deeply excavated under the apex of the process, is

simply strongly declivous. There is also marked variation in the

width of the process and its degree of obtuseness, in some specimens

being very broadly rounded and in others very narrowly so, in the

latter case leaving much more of the declivous mesosternum visible

at the sides of the apex.

The dense aciculato-reticulate sculpture, which is unique, and the

single discal stria, taken in connection with the sternal and tarsal

characters of Olibrus, show that this species is an isolated and highly

specialized form, without any near congeners—although in rujipes

there is a feeble indication of the sculpture here so highly developed ;—

and for this reason, as well as the fact that there appears to be no

stability in the variations observed, it is impossible to specifically

divide the large amount of material before me.

OLIBROPORUS ». gen.

Base of the antenne entirely exposed in deep frontal emarginations just

before the eyes. Scutellum small. Elytra with a single discal stria, the

sutural bead completely wanting. Prosternal process rather narrow, abruptly

inflexed at apex, the latter not setose. Mesosternum forming a minute bead

along the apex of the very broad, transversely truncate metasternal process,

the latter not advancing beyond the coxe, the mesosternum not developed

behind the middle acetabula, forming merely a beaded margin. Legs short

and robust; terminal spurs of posterior tibiz# small, slender, slightly unequal ;

posterior tarsi moderate, cylindrical ; basal joint obliquely truncate and pro-

longed beneath the second, the articulation rigid ; second joint moderate in

length, scarcely twice as long as the first.

These few words will serve to characterize a genus intermediate

in some characters between Stilbus and Olibrus, and combining also

several of the structural features of other genera. The apex of the

prosternal process is more abruptly inflexed than is usual in Olibrus,

but the edge is not as free and acute as in Stilbus.

0. punctatus n. sp.—Rather broadly, evenly elliptical, convex, strongly

shining, black above, rufo-testaceous throughout beneath; antennz same.

Head short, very minutely, rather feebly punctate; eyes large, not margined

internally ; antenne moderate, third joint nearly as long as the next two, club

large, longer than the funicle, elongate-elliptical, strongly compressed, the

eleventh joint but slightly longer than wide, one-half longer than the tenth,

the terminal process not well defined and obtusely rounded. Prothorax very

short, almost three times as wide as long, strongly narrowed from base to apex ;

sides arcuate and continuous in curvature with those of the elytra; basal lobe

almost obsolete; basal bead fine, very strong and continuing to within a very

short distance of the basal angles, the posterior margin of the basal bead finely

granulato-aciculate; disk very minutely, feebly and not very densely punc-

tate, the punctures rather larger and denser near the lateral edges ; the latter

margined with a broad flattened bead which becomes very wide around the

apical angles. Scutellum very small, slightly wider than long, pointed ; sides

broadly arcuate. lytra more than three times as long as the prothorax, not

narrowed toward apex, the latter very broadly, evenly rounded; transverse

basal stria fine, deeply impressed, abruptly ending at the base of the scutellum,

which it attains, but at which point it is not in the least reflexed ; anterior half

of the basal bead—formed by the basal stria—longitudinally granulato-acicu-

late; discal stria very deeply impressed, coincident with the suture at the

apex, and very gradually evanescent at basal fourth, becoming an unimpressed

row of punctures; disk rather coarsely reticulate in transverse wavy lines,

112 Coleopterological Notices.

having nine very even rows of large, rather closely placed, deeply impressed

and slightly elongate punctures, which are equal in size throughout the width,

and not in the least dilated laterally, the rows almost attaining the base and

not accompanied by impressed lines ; intervals flat, with uneven single rows

of fine punctures. Metasternum shining, very finely, sparsely, subasperately

punctate, coarsely and sparsely pubescent. Length 1.9 mm.

Florida.

The widely spaced, perfectly even rows of deeply impressed punc-

tures, distinguish this species from any other of the family, but

recall to a considerable degree the punctuation of Phalacrus seria-

tus; in the latter, however, the series of the intervals are as distinct

as the others, so that the regular rows are twice as numerous as in

the species here described. The general character of these punc-

tures is perfectly similar to the prevailing type in Olibrus.

EULITRUS Sharp.

Head extremely minutely but distinctly and not very sparsely puuctate,

with several larger, widely dispersed punctures toward the sides of the front.

Epistoma transversely, feebly arcuate; sides widely divergent posteriorly,

the antennal sinuations feeble, a very small portion of the basal joint con-

cealed. Antenne rather long; basal joint large, much longer and more robust

than the second; third scarcely as long as the next two combined; outer

joints of funicle slightly more robust, the eighth wider than long; club long,

loose ; ninth and tenth joints triangular, subequal in length, ninth to eleventh

much more developed on their anterior sides, the last much shorter than the

two preceding together. Ligula short and very broad, the paragloss corne-

ous, connate, pointed at the sides, extending laterally beyond the subquad-

rate mentum. Palpi robust; last joint of the labial slightly swollen, as long

as the two preceding; fourth joint of the maxillary subcylindrical, obtusely

pointed, as long as the two preceding together. Prosternal process inflexed

at apex, not at all setose, moderate in width. Metasternal process very wide

and long, extending beyond the coxe and resting in repose upon the prosternal

process which is feebly impressed, strongly evenly rounded at apex. Meso-

sternum forming a fine beaded margin along the apex and coxal cavities, and

expanded behind the latter, becoming here about three times as wide. Legs

moderately robust; tibial spurs long, strong, unequal; posterior tarsi rather

long, cylindrical ; basal joint short, almost rigidly anchylosed to the second,

and not extending beneath it; second joint extremely long, nearly four times

as long as the first and about one-half longer than the entire remainder, not

very densely clothed throughout with short robust closely recumbent spinose

sete ; fourth joint very distinct as a basal node of the last; third not in the

least dilated, obliquely lobed beneath.

In addition to the above characters, it should be mentioned that

the elytra are entirely destitute of any trace of discal striz, although

Coleopterological Notices. 113

the suture is very finely beaded, the bead becoming obsolete before

attaining the base. The scutellum is small, and the elytra are

rendered feebly opalescent by an excessively minute transverse

strigilation, which is just resolvable under a power of 80. The

punctures are small, feebly crescentiform and disposed in rather

approximate but not very regular rows, becoming wider and more

confused near the sides.

The description is taken from the typical Central American L.

estriatus Sharp, one of the largest and finest species of the family.

The affinities of Eulitrus are evidently strongly toward Olibrus,

and it bears very much the same relation to that genus that Acylo-

mus bears to Stilbus. The feeble dilatation of the mesosternum

behind the middle acetabula, shows also that it should form one of

a series joining Olibrus and Acylomus or Stilbus. No species has

yet been discovered within the United States.

LITOLIBRUS Sharp.

The nearest ally to this genus is probably Acylomus, from which

it differs primarily in four important characters as follows :—

1. The mesosternum is not produced at all behind the middle

acetabula, being reduced to a simple fine bead forming the margin

of the cavity, as in Olibrus.

2. The metasternal process is very narrow and much shorter.

3. The sexual modification of the posterior tibiz, tibial spurs, and

tarsi does not apparently exist, and the second joint in the male is

not spongiose beneath.

4. The basal joint of the posterior tarsi is extremely obliquely

truncate at apex, and extends more or less beneath the second joint,

this being more noticeable in the northern forms than in the typical

obesus where, however, it is also very marked. In Acylomus the

apex of the first joint is only slightly oblique, and its lower surface

does not extend at all beneath the second. In both genera the

connection between these joints is rigid, apparently admitting of

but little, if any motion, but the line of demarcation is rather

stronger in Litolibrus than in Acylomus.

Both of the genera here compared differ greatly from Stilbus in

the very elongate second joint, and Litolibrus differs from Acylomus

as well as Stilbus in its extremely robust legs, especially the middle

and posterior femora and tibie.

This genus is one of the most distinct of the family, ranking, in

large oblique oval spot on each elytron before the middle, attaining the suture,

the lateral margin and apex narrowly, entire under surface, legs and antenne

pale rufo-testaceous; remainder of the elytra black. Head polished, some-

what coarsely, sparsely and feebly punctate; eyes large, their inner margin

slightly elevated above the general surface of the vertex ; epistoma without a

beaded margin, except laterally along the antennal sinuations ; antenne rather

long and robust, joints three to five decreasing uniformly and very slightly in

length, outer joints of funicle slightly more robust, seventh and eighth equal

in length, the latter just visibly wider than long, club rather robust, strongly

asymmetric, the anterior sides much more strongly angulate, and the eleventh

joint slightly lobed on this side near the base, longer than the two preceding

together. Prothorax much more than twice as wide as long, not reticulate,

very minutely and obsoletely, but somewhat densely punctate; basai lobe

moderate, broadly, evenly arcuate, the basal bead fine, very strong, extending

laterally to within one-fourth the width of the sides, with its posterior margin

finely and very strongly granulose. Scutellum equilatero-triangular, small,

the sides very feebly arcuate. /ytra polished, the transverse strigilation so

minute as to be merely suggested by a very feeble opalescence under high

power, having rows of very small, rounded punctures which are larger, deeper

and more distinct at the sides, always crescentiform, the intervals with an

obscurely double line of nearly similar punctures; discal stria obsolete at

basal third. Abdomen coarsely, sparsely pubescent. Legs short and very

stout, the posterior tibiz short, obliquely truncate at apex, the truncation

sinuate; spurs very long, stout, and distinctly unequal, the corresponding

tarsi nearly as long as the tibiz, the first joint short above, very strongly pro-

dnced beneath the second; second joint arcuate above near the base, more

than four times as long as the upper or shorter side of the basal joint, and

very much longer than the entire remainder. Length 2.6 mm.

The metasternal process is narrow and very short, flat, inipune-

tate, truncate at apex, the mesosternum in front of it abruptly

declivous, and extending laterally so as to slightly envelop the

middle coxe, having one or two robust sete at the sides near the

coxe and metasternum, not at all prominent; prosternal process

moderate, with two or three very fine feebly developed sete.

Coleopterological Notices. 115

This is an extremely distinct species in many characters, especi-

ally those of the antennz, mesosternum and posterior tarsi, but it

does not differ generically from Z. obesus. The species described as

varians by Dr. Sharp (Biol. Cent.-Amer. Col., II, i, p. 260), does

not appear to differ specifically, and, in accordance with the theory

of distribution by ocean currents from Central America to Florida,

formerly held by Dr. LeConte (Proc. Am. Phil. Soc., X VII, p. 471),

and more recently demonstrated by Mr. Schwarz (Proc. Ent. Soc.

Wash., I, p. 145), the proposed synonymy is rendered highly pro-

bable.

L. uniformis n. sp.—Somewhat broadly, evenly oval, very strongly

convex, pale ochreous-flavate throughout, strongly shining. Head not reticu-

late, extremely minutely, obsoletely and sparsely punctate, with a few scattered

punctures of larger size near the eyes; the latter moderate, the inner margin

and beaded edge of the epistoma as in princeps; antennze moderate, funicle

slender, third joint much shorter than the next two combined, fourth slightly

shorter than the fifth, eighth very slightly shorter than the seventh, a little

wider than long, club robust, fusiform, nearly symmetrical, eleventh joint fully

as long as the two preceding combined. Prothorax distinctly more than twice

as wide as long; basal lobe very broad and extremely feeble, the bead fine but

strong, continuing laterally to within one-fifth the width of the sides, with

the posterior margin finely and strongly granulose; surface polished and

almost completely devoid of punctuation. Scutellum equilatero-triangular,

the sides feebly arcuate. Elytra distinctly opalescent, having widely distant

rows of moderate punctures, which are more deeply impressed and very dis-

tinct toward the suture, aud more broadly crescentiform but rather more feebly

impressed near the sides and apex, obsolete toward base; intervals with a few

widely dispersed, excessively minute punctures ; sutural stria distinct, obsolete

at basal third or fourth, the transverse strigilation excessively minute and

dense, not resolvable under high power. Abdomen reticulate, sparsely pubes-

cent, the rows of robust setz at the apices of the segments especially promi-

nent. Jegs short and very stout; obliquity of truncation of the posterior

tibie rather slight, the spurs long and strong, the tarsi rather slender, more

symmetrical than in princeps, the basal joint less strongly produced beneath

the second, the latter seven or eight times as long as the first on the upper

side, and slightly more than twice as long on the lower side, sparsely clothed

with very short recumbent sete, and much longer than the entire remainder.

two and three times as wide as at the narrowest part, the apical

margin bearing two short stiff sete.

This species appears to be distinct from any of those recently

described by Dr. Sharp; mznor, which undoubtedly resembles it in

color and size, has the club of the antenne short and broad, and

“developed on one side only of the mesial line.”

ACYLOMUS Sharp.

Although bearing a certain general resemblance to Stilbus, this

genus possesses two characters which render it one of the most

remarkable of the entire family.

The first character is not entirely peculiar, as it reappears to a

less marked degree in Litochropus; it relates to sexual modifica-

tions affecting the posterior tibie. In the males these increase

strongly in width from base to apex; they are obliquely truncate,

and have the terminal spurs extremely unequal, the smaller being

longer than usual in Stilbus, and the other greatly developed, being

sometimes between one-third and one-fourth as long as the entire

tibia, and generally slightly contorted toward apex. In the female

the tibie are normally and sometimes unusually slender, trans-

versely truncate, and have the terminal spurs of the usual form,

although much longer, stouter and more unequal than in Stilbus.

The other character relates to the vestiture of the under surface

of the second joint of the posterior tarsi, which, in the males, is of

a densely spongiose nature, similar to the under surface of the

anterior tarsi in the males of Anisodactylus. This character seems

to be absolutely peculiar to Acylomus, and is most highly developed

in the typical A. aciculatus Sharp.

In the genus Acylomus the second joint of the ene tarsi is

very much more elongate than in Stilbus, and the basal joint corre-

spondingly abbreviated, the connection between the two being more

rigid. The structure of the mesosternum is nearly similar, but its

extension behind the iniddle cox generally less, being intermediate

in this respect between Stilbus and Litolibrus; it is also a connect-

ing link between these two genera in the sculpture of the elytra,

the reticulation of the surface when present in Stilbus being coarser

and tending less to a transverse arrangement in wavy lines, while

in Litolibrus it is very much finer, taking the form of a more regu-

lar transverse strigilation, of such excessive minuteness and close-

Coleopterological Notices. 117

ness that it cannot be distinctly resolved by the highest ordinary

working powers of the microscope; it is to this natural optical

diffraction-grating, that the opalescence observable in most of the

species is due; the same effect from a similar cause is more familiar

to us, and even more strongly developed, in Selenophorus of the

Harpalini.

The elytral punctures prevailing in the genus are very strongly

transversely crescentiform, being much more highly developed than

even the most extreme cases which J have observed in Stilbus ; this

character is also very marked in the Litochride genera. The sete

at the apex of the prosternal process are less highly developed than

in Stilbus, being generally shorter and sometimes reduced in num-

ber to two, situated at the apical angles. The metasternal process

is generally rather longer than in Stilbus, somewhat variable in

width, and is usually slightly dilated at the immediate apex, the

tumid mesosternum before it being almost invariably shorter.

The species are probably moderately numerous in the United

States; the five which I have before me may be separated as

follows :—

Color throughout the upper surface piceous or black.

Form evenly elliptical or suboblong, not at all attenuate behind.

longer than the tenth, the latter slightly transverse, eleventh nearly as long

as the two preceding together. Prothorax more than twice as wide as long,

distinctly, broadly lobed at the middle of the base, and finely but distinctly

beaded; surface excessively minutely, sparsely punctate, polished toward

apex, very minutely strigilate in wavy transverse lines which are distinct

toward base and obsolete toward apex. Scutellum ogival, uearly as long as

wide. Elytra finely and very distinctly strigilate in transverse wavy lines

throughout, having rows of broadly crescentiform, feebly impressed punctures,

which are but slightly wider at the sides, where they are more approximate

laterally, and becoming obsolete near the base; discal stria distinct, obsolete

at basal two-fifths. Abdomen coarsely, sparsely pubescent, shining, coarsely

reticulate. Legs moderate, the posterior femora not unusually robust; tibie

feebly dilated from base to apex, the apical truncation slightly oblique, very

sparsely setose, having an internal and external line of fine erect setiform

spines, the terminal spurs extremely unequal, the larger feebly contorted, as

long as the apical width of the tibia; corresponding tarsi very slender, cylin-

drical, with the second joint nearly four times as long as the first, and longer

than the entire remainder, the under surface spongy-pubescent only in the

apical half. Length 1.4-1.7 mm.

Texas (Galveston and Austin).

The description is taken from the male; the female has the poste-

rior tibia nearly equal in width throughout, and rather sender, the

terminal spurs smaller and more slender, but decidedly unequal, the

longer one being still as long as the apical width; the tarsi are

more slender, with the second joint rather shorter and not spongiose

beneath.

The metasternum is very minutely, sparsely punctate, very

sparsely pubescent, the process very wide, rather long, slightly and

abruptly dilated at the immediate apex, the mesosternum in front

of it transverse and very short, not distinctly tumid, the prosternal

process rather wide, the free apex very feebly, broadly arcuate, and

having but two short spinose setee—one at each angle.

A. extricatus n. sp.—Elongate, evenly elliptical, nearly twice as long

as wide, piceous above, dark rufo-testaceous throughout beneath; elytra sub-

alutaceous. Head very strongly retractile; antennze moderate, outer joints of

funicle slightly robust, club very distinctly increasing in width from base to

apex, ninth joint scarcely longer than the tenth, the eleventh as long as the

two preceding together. Prothorax but slightly more than twice as wide as long,

very broadly, strongly lobed in the middle of the base, the beaded margin dis-

tinct ; surface polished, very minutely, transversely strigilate in wavy lines

which are very distinct toward base and nearly obsolete toward apex. Scu-

tellum very small, ogival, slightly wider than long, the sides strongly arcuate.

Coleopterological Notices. 119

Elytra more than three times as long as the prothorax, having rows of moderate

crescentiform punctures which, at the sides, become very strongly transverse,

sometimes confluent, and more or less confused in arrangement; intervals

toward the suture each with a row of similar punctures, but about one-half as

wide; discal stria distinct, obsolete at basal third; surface rather coarsely

strigilate in wavy transverse rows throughout. Abdomen uearly as in calca-

ratus. Legs moderate. Length 1.8 mm.

Texas.

This species is closely related to calcaratus, but differs in its

much more elongate, slightly less convex form. It is described

from the female, and the posterior tibial spurs are rather less de-

veloped and less unequal than in the corresponding sex of calca-

ratus; the tarsi are nearly similar in structure. In calearatus the

apex of the prosternal process has, without exception, only two

terminal sete, while in the present species there is a row of four or

five which are longer, and nearly twice as stout; this constitutes

one of the most decisive points of difference between these species.

The head is so far retracted within the prothorax in the type as to

be invisible from above.

A. ergotin. sp. (Walsh MS.)—Strongly convex, almost evenly elliptical,

one-half to two-thirds longer than wide, the male slightly the shorter, black

above, pale flavo-testaceous throughout beneath; lustre strongly shining. Head

very minutely, sparsely punctate, polished, not reticulate; eyes rather large ;

antenne nearly as in calcaratus, but with the outer joints rather more robust,

and the club more strongly narrowed from apex to base. Prothorar polished

throughout, toward base excessively obsoletely transversely strigilate in wavy

lines, the punctures extremely minute and sparse; basal lobe and beaded

margin distinct, the latter not extending laterally further than the lobe. Scu-

tellum equilatero-triangular, with the sides very feebly arcuate. Elytra sub-

alutaceous, very minutely, transversely strigilate in wavy lines, having rows

of punctures which, toward the suture, are very minute and feeble, and toward

the sides slightly larger, always transversely crescentiform ; discal stria dis-

tinct, obsolete at basal two-fifths. Abdomen coarsely reticulate, moderately

shining, coarsely, sparsely pubescent. Legs moderate; posterior tibie increas-

ing very rapidly in width from base to apex, very obliquely truncate ; spurs

nearly as in calcaratus; tarsi very long and slender, three-fourths as long as

the tibiz, with the second joint between three and four times as long as the

basal, and spongiose throughout beneath, except at the immediate base.

Length 1.8-2.2 mm.

Pennsylvania; Delaware; Iowa; Texas.

The description is drawn from one of the Iowan males; the

female is larger, rather more convex, and has the posterior tibie

more slender, the spurs being smaller and less unequal than in the

female of calcaratus, the longer one much shorter than the apical

width of the tibia.

The sternal structure is nearly the same as in calcaratus, but the

metasternal process is rather less broad, and the mesosternum is

more developed behind the middle acetabula. The terminal sete of

the prosternal process are about three in number, extremely short,

being much shorter than in calcaratus.

This species is widely distributed, and differs from the preceding

in its larger size, black color, more convex form, finer elytral sculp-

ture and punctuation, more especially in the rows toward the suture,

and, more decidedly, in the greater dilatation and obliquity of trun-

cation of the posterior tibiz in the male. It varies considerably in

size.

A. piceus n. sp.—Broadly oval, rather pale fusco-piceous above, very pale

brownish-flavate throughout beneath, polished, the elytra feebly alutaceous,

moderately convex ; sides feebly convergent behind from the base of the elytra.

Head not reticulate, extremely finely and feebly punctate; eyes moderate ;

apical margin of the front with two minute fovez on each side just above the

insertion of the antenne, the latter rather slender, the third joint distinctly

shorter than the next two together; club elongate, very slender, symmetrical,

parallel and rather loose; ninth joint slightly longer than wide and a little

longer than the tenth, the latter nearly as long as wide and not wider than

the ninth, the eleventh elongate, nearly as long as the two preceding, obtusely

rounded at the apex, without trace of terminal process. Prothorax between

two and three times as wide as long, very strongly narrowed from base to

apex ; basal lobe very feeble, the bead strong but very short, not extending

laterally beyond the lobe; disk with feeble traces of transverse reticulation

toward base ; punctures almost obsolete. Scutellum scarcely wider than long,

ogival, with the sides slightly arcuate. lytra rather short, about two and

one-half times as long as the prothorax, evenly and not very broadly rounded

at apex; surface very minutely and rather strongly transversely strigilate in

wavy lines throughout, except near the base, where the sculpture becomes very

feeble, having series of small transversely crescentiform punctures, which are

feebly impressed and which are not much wider or more distinct toward the

sides, the series accompanied by fine feebly impressed lines, the intervals with

uneven series of excessively minute feeble punctures of the same nature; all

the punctures becoming gradually obsolete in basal third ; discal stria fine but

distinct, obsolete at basal third. Length 1.9 mm.

and extremely slender. The metasternal process is rather narrower

than usual in this genus.

A. nebulosus n. sp.—Very broadly oval and moderately convex, about

one-half longer than wide; elytra feebly attenuate from base to near the apex,

then conjointly evenly rounded, subalutaceous, castaneous ; head, pronotum,

each elytron obliquely at apex, and a small indefinite spot at the base of each

elytron, nearer the humerus than the scutellum, paler, rufo-testaceous ; under

surface, legs and antennz very pale testaceous. Head extremely minutely,

sparsely punctate, not reticulate; eyes moderate; antenne slender, joints one

to eight elongate, club moderate, the eleventh joint about as long as the two

preceding together. Prothorar distinctly more than twice as wide as long;

basal lobe very broad, feeble, transverse opposite the scutellum; bead fine

but rather distinct, not extending laterally beyond the lobe; surface polished,

extremely minutely and obsoletely punctate, very feebly strigilate in wavy

transverse lines which become almost obsolete toward apex. Scutellum ogival,

slightly wider than long. Elytra strongly and distinctly, but very minutely

strigilato-reticulate in broken transverse wavy lines throughout, alutaceous

in lustre, having series of very small feeble crescentiform punctures which

become larger laterally, and rather confused near the sides; intervals each

with a very irregular line of similar though extremely fine punctures ; discal

stria fine but distinct, obsolete at basal fourth. Abdomen reticulate, very

sparsely pubescent. Legs moderate, the posterior femora not unusually

robust. Length 2.2 mm.

California (Fort Yuma).

The posterior tibiz are but slightly more robust and dilated in

the male, the terminal spurs in that sex being extremely unequal,

the longer nearly three times as long as the shorter, and rather

longer than the apical width, the corresponding tarsi being rather

robust, the second joint nearly four times as long as the first, and

slightly longer than the entire remainder, spongiose along the mid-

dle beneath throughout the length, the spongiose area being limited

laterally, as usual, by two lines of long, very closely-placed and

slender sete ; first joint not at all produced beneath the second, the

attachment apparently rigid. In the female the spurs are smaller

and more nearly equal, the larger but twice as long as the smaller,

the tarsi more slender, especially the second joint which is not

spongiose beneath.

The metasternal process is very broad, and the sternal structure

in general very similar to that of the typical forms.

The sete at the apex of the prosternal process appear to be nor-

mally three in number, but the middle one is occasionally absent, and

there may sometimes be one which is superfluous and sporadic. In

the female they are more than twice as long and stout as in the

male, being extremely minute in the latter sex.

The discovery of this peculiar secondary sexual character proves

that these terminal sete play a more important part in the economy

of the insect than has been hitherto supposed, and that the gap

separating those genera possessing them from those in which they

are wanting, as for instance Stilbus and Olibrus, is even correspond-

ingly greater. It aiso indicates that any classification of the species

in genera possessing these sete, based in any way upon them, must

be used with more or less caution. It is only fair to state, however,

that L have not been able to discover similar sexual variation in

Stilbus, where I have separated several species because of the abnor-

nal shortness of these sete, and in this particular case it is of very

little consequence, as the four species constituting the second group

are so distinct in other characters that they can be easily identified,

and after all this is the main object of taxonomical tables in such

preliminary and superficial studies as the present is necessarily

forced to be.

The terminal sete in A. calcaratus also differ sexually, but only

to a slight degree, being a little longer in the female; they are, in

that species, very persistently two in number.

Besides being aberrant in this way, the present species differs

greatly in coloration from the others, reminding us somewhat, but

in facies only, of Stilbus viduus. It also appears to resemble the

Central American Olibrus submaculatus Sharp, especially in colora-

tion, but the sculpture and punctuation seem to be much more pro-

nounced and evident than in that species.

LIOPHALACRUS Sharp.

The single specimen of the typical Z. bicolor before me is in a

very imperfect state, so that I cannot examine the mouth-parts or

antenne ; otherwise it is extremely closely allied to Stilbus, and

differs only in the structure of the posterior tarsi, which are com-

paratively short and slender, cylindrical, with the proportional

length of the joints as in Stilbus, but with the first joint rigidly

anchylosed to the second. The second joint is not remarkably long,

and not quite twice as long as the first, the third being slightly

dilated and deeply emarginate above. In Stilbus the articulation

Coleopterological Notices. 123

between the first and second joints is much less rigid and the motion

apparently perfectly free.

In ZL. bicolor the metasternal process is wide, strongly rounded

throughout at apex, and does not extend to the anterior limits of

the coxe; the mesosternum in front of it forms a perfectly flat

transverse piece, rather long, projecting beyond the cox, with the

apex transversely truncate, and the surface bearing a transversely

arcuate row of robust recumbent spinose sete, projecting posteriorly,

the line of demarcation between it and the mesosternum extremely

fine. Behind the middle acetabula the mesosternum is very strongly

developed, the piece being posteriorly produced in a slender cusp,

extending almost to within one-third the length of the metasternum

of the posterior margin of the latter. The prosternal process is rather

wide, the posterior edge being free, acute, transversely truncate, and

bearing a series of four or five erect robust and prominent spinose

sete.

On the upper surface the sutural bead is entirely obsolete, and

the single discal stria fine, close to the suture, and rather short.

The sculpture consists of very fine transverse strigilation which,

however, is not sufficiently fine and close to produce an opalescent

lustre. The punctures throughout are extremely minute and feeble,

not transversely crescentiform, and not more distinct at the sides,

in this respect being exactly similar to many species of Stilbus.

No species of this Central American genus has yet occurred

within the United States.

STILBUS Seid.

Olistherus! Seid. ;—Eustilbus? Sharp.

Some of the structural characters distinguishing this genus have

been before indicated, and it is only necessary to state in general

that it differs from Olibrus in its short metasternal process, promi-

nent and tumid mesosternum, extension of the latter behind the

middle acetabula, in the form of the prosternal process which is here

furnished with a distinct free edge posteriorly, and armed with a

transverse series of stout setiform spinules, in the absence of a bead

along the elytral suture, in the form of the eleventh joint of the

some extent different from Olistherus.

124 Coleopterological Notices.

antenn which is not constricted in apical third, and in the form of

the fourth joint of the maxillary palpi which is distinctly more

robust and securiform.

It resembles Olibrus in the mode of antennal insertion, but differs

radically in this respect from Phalacrus. Its relationship with

Acylomus and Litolibrus has been mentioned under those genera.

The posterior tibial spurs are generally very small, slender and

subequal, and in some species become quite as insignificant as in

Phalacrus. The basa! joints of the posterior tarsi are simply densely

setose beneath, the second joint being but. moderately elongate,

generally nearly twice as long as the first, but in nitidus relatively

shorter and but slightly longer than the first. The sculpture varies

from the completely polished, as seen in apicalis, to a rather coarse

and very strong reticulation throughout the upper surface, as seen

in subalutaceus. The punctures are generally very minute and

obscure, sometimes almost completely obsolete, the broadly crescen-

tiform type being rare and exceptional. In pusillus, modestus,

attenuatus, and elongatulus, the punctures become deeper and more

distinct on certain limited portions of the elytral disk.

Our species are moderately abundant, usually widely distributed,

and are somewhat diversified in structure. The four species as-

signed to group II, differ each very greatly from those of group I,

in several peculiarities of structure or sculpture, but at the same

time differ from each other to quite as great a degree. In general,

the reticulation of the elytral surface, when present, is relatively

somewhat coarse, and does not exhibit the transversely wavy lines

so perfectly as in Acylomus; in convergens and attenuatus it is

replaced by a very minute wavy strigilation which, however, is

not sufficiently fine to produce an opalescent effect as in Litolibrus. |

The metasternal process is rather narrow, extending about two-

thirds the length of the coxw, the mesosternum being strongly

are narrowly and very feebly prolonged behind.

This common species, which seems to vary considerably in dis-

tinctness of coloration, is quite different from the European consi-

milis, in form, size, coloration, and especially sculpture. The entire

surface of the European insect is minutely, but distinetly strigilato-

reticulate.

North Carolina; Texas; Arizona.

This species resembles apicalis in sculpture, but is decidedly

more robust, paler in color, with the apical pale area less defined

than in the mature specimens of apicalis; the sternal characters are

nearly as in that species, but the antennal club is more robust

toward apex, and the tibial spurs are also more robust.

The type is a male and exhibits the strongest sexual characters

which I have observed in the genus. The third segment of the

abdomen has, just before the apex, a short broad porrected tooth in

the middle, which does not extend beyond the apical margin, and

bears along its apex seven or eight very short robust porrected

spinules. The fourth segment has a feeble median impression, and

the fifth has the usual very feebly defined transverse impression

near the apex.

8, pallidus n. sp.—Evenly elliptical, about two-fifths longer than wide,

polished, pale flavo-testaceous throughout. Head very finely, feebly punc-

tate; antenne slender, club slender, compact, third joint scarcely as long as

the next two combined, fourth shorter than the fifth. Prothorar very distinctly

more than twice as wide as long; punctuation obsolete ; basal lobe extremely

feeble, the bead obsolete. Scutellum ogival, wider than long. L/ytra nearly

as in apicalis, except that they are less attenuate and rather more broadly

rounded behind, uniform testaceous in color, and with a very feeble obsolete

reticulation near the apex. Abdomen very feebly reticulate, the reticulation

very fine, dense and strong toward the base of the basal segment. Legs

moderate or rather short; spurs of posterior tibi# very small, slender ; poste-

rior tarsi three-fourths as long as the tibie; basal joint two-thirds as long as

the second and more robust; first and second sparsely, finely spinose beneath ;

third slightly dilated, bilobed, with a tuft of whitish hair beneath. Length

Rhode Island.

The sternal characters are nearly as in apicalis, from which this

species differs in its smaller size, pale uniform color, relatively

slightly longer basal joint of the hind tarsi, and finer, stronger and

denser reticulation along the base of the abdomen. The reticulation

at the apices of the elytra, although very feeble, is more distinct

than in apicalis, where it is all but totally obsolete; in pallidus it

is distinetly traceable over most of the apical half of the elytra,

being especially noticeable in lines accompanying the series of

punctures.

The species is represented by two specimens which do not indi-

cate any variation.

throughout, very convex, strongly shining, totaily impunctate, the fine re-

cumbent hairs rather long. Head very feebly reticulate in transverse wavy

lines; antenne rather robust, third joint shorter than the next two together,

distinctly clavate, fourth shorter than the fifth, outer joints of funicle more

robust, club moderate, slightly more robust toward apex, ninth scarcely

longer and a little narrower than the tenth, eleventh two-thirds longer than

the tenth. Prothorax rather more than twice as wide as long, very obsoletely

reticulate; basal lobe and bead almost completely obsolete. Scutellum ogival,

wider than long. Elytra slightly attenuate and narrowly rounded at apex,

the discal stria very narrowly separated from the suture at apex, obsolete at

basal third; surface minutely and distinctly reticulate in transverse wavy

lines throughout, the minute recumbent hairs arranged in regular series, the

punctures not evident, each being entirely filled by the hair. Abdomen feebly,

coarsely reticulate, distinctly asperately punctate, coarsely pubescent. Legs

rather short and robust; tibie,short and broad, coarsely spinose; terminal

spurs of the posterior very minute, subequal, not longer than some of the

spinules of the terminal fimbria; corresponding tarsi short, very slightly

longer than the anterior, the basal joint relatively long about three-fourths

as long as the second which is shorter than usual. Length 1.3 mm.

New York; Iowa; Texas.

The metasternum is reticulate at the sides, the process moderate

in width, coarsely sparsely setose, the mesosternum in front of it

much broader and distinctly prominent.

This minute species is very distinct and, as far as I have seen,

has no very-close allies; it is the only species in which the punc-

tures of the elytral series become completely invisible, and confused

with the fine reticulation of the surface. In very pale specimens

the chitinous cells of the elytra surrounding the base of the hairs

become darker, giving the appearance of series of coarse areole or

punctures by transmitted light and under low magnifying power.

The form of the body is extremely convex, resembling some of the

small convex species of Cereyon.

The minute setigerous punctures of the elytra, described under

Phalacrus, are observable here to a very limited extent.

feebly reticulate, ogival, with the sides strongly arcuate, one-half wider than

apex; discal stria as in obtusus; surface finely but strongly and distinctly

reticulate in wavy lines, subalutaceous in lustre; punctures of series very

evident, coarser and distinctly crescentiform in the rows toward the suture

and the sides, smaller and feebler but still distinctly crescentiform in the

median rows. Abdomen coarsely pubescent, distinctly reticulate, rather strongly,

asperately punctate, especially as usual toward the middle and apex. Legs

moderate ; posterior tibie rather slender, sparsely and coarsely setose ; spurs

small and rather distinctly unequal, not longer than the outer spinules, the

same tarsi setose beneath, moderate in length, with the basal joint one-half as

long as the second. Length 1.8 mm.

California.

The metasternum is reticulate but not distinctly punctate, very

sparsely and rather coarsely pubescent; the sternum and sternal

processes throughout are nearly as in obtusus, from which this

species differs in its pale color, more distinct reticulation, and very

notably in the character and strength of the elytral punctures. It

is rare, and although fortunate enough to secure a single specimen

myself, I am not certain of the exact locality ; it is, however, pro-

bably southern. ;

extremely feebly, finely reticulate, the punctures very sparse and excessively

minute; eyes moderate; antenne slender, the club abrupt, rather small and

slender and scarcely as long as the five preceding joints combined, ninth and

tenth joints subequal, slightly transverse, eleventh oval, longer than wide,

obtusely rounded at apex and rather shorter than the two preceding. Protho-

and under surface pale testaceous ; upper surface polished. Head extremely

feebly and sparsely punctate ; antenne rather slender, third joint shorter than

the next two together, fourth much shorter than the fifth, club rather slender,

sides nearly parallel, ninth joint much longer than the tenth and slightly

shorter than the eleventh. Prothorax scarcely visibly and very sparsely

punctate, not reticulate ; basal lobe very broad and feeble, the marginal bead

almost obsolete. Scutellum one-half wider than long. /ytra more strongly

vicinity of the base, where they become obsolete, generally in very broken wavy

lines on the upper portions of the disk. Abdomen very strongly reticulate, the

portions very near the base, and also the metasternum toward the sides, almost

granulose. Legs moderate; posterior tarsi rather short and robust, scarcely

two-thirds as long as the tibie, setose beneath, the first joint two-thirds as long

as the second ; tibial spurs small. Length 1.8-2.0 mm.

Iowa. Mr. Wickham.

The metasternal process is rather wider than in apicalis, and the

mesosternum in front of it is very strongly tumid and prominent.

The sexual characters are nearly as in viduus, except that the tooth

of the third segment is more deflexed, with the spinules excessively

short. This species is very easily distinguishable from apicalis and

viduus by its small size, more rounded form, dark piceous color,

which does not become noticeably paler at apex except from the

transparency of the elytra, and by the reticulation of the upper

surface ; it is represented by a good series of specimens, and does

not vary appreciably.

S. obtusus Lec.—Proc. Ac. Phil., 1856, p. 17.—Almost evenly elliptical,

moderately convex, blackish-piceous throughout the body, legs and antenne ;

tarsi slightly paler; upper surface shining. Head very feebly and sparsely

punctate; antenne nearly as in nitidus, but with the ninth joint rather longer.

Prothorar extremely minutely, feebly and sparsely punctate, extremely obso-

letely reticulate in broken wavy lines; basal lobe very broad and feeble, the

bead very fine but somewhat distinct. Scutellum one-half wider than long.

Elytra rather obtusely rounded behind, finely but rather distinctly reticulate

in transverse wavy lines over the entire disk ; discal stria very strong, coinci-

dent with the suture at the apex, becoming obsolete at basal third or fourth ;

punctures of the series very fine and feeble but visible, not more distinct but

rather wider at the sides, where, however, they do not become crescentiform,

but simply a slight deepening of the lines forming the reticulation at the

points of attachment of the hairs. Abdomen reticulate, sparsely, coarsely

pubescent. Legs moderate; spurs of posterior tibiz very small, subequal, and

about as long as the exterior spinules of the terminal fimbria; the correspond-

ing tarsi rather slender, nearly three-fourths as long as the tibize, with the

basal joint one-half as long as the second. Length 1.5 mm.

California (Santa Cruz Co.).

The metasternal process in this species is rather broad, reticulate

but not distinctly punctate, the mesosternum transversely, moder-

ately prominent in front of it, the prosternal process strongly

dilated and broadly rounded at apex, the spinules rather close and

very stout, distinctly shorter than in apicalis, but rather longer

than in attenuatus, in this respect approaching the second of the

arbitrary groups into which I have divided the genus.

The type of LeConte seems to be an unusually robust specimen,

and I have several which are distinctly narrower. The under sur-

face and antenne are sometimes paler from immaturity.

S. nanulus n. sp.—Narrowly and evenly elliptical, strongly convex,

highly polished, piceous-black throughout above; legs, antenne and under

surface testaceous. Head without trace of punctuation or reticulation ;

antenne rather short, the funicle very slender, the outer joints more robust,

the tenth, the eleventh almost as long as the two preceding together, although

moderate in length. Prothorax impunctate and not at all reticulate, the median

basal lobe broadly arcuate and rather well developed, the marginal bead obso-

lete. Scutellum small, ogival, about two-thirds wider than long. E/ytra highly

polished, without trace of reticulation except near the apex and narrowly along

the sides, where it is very feeble and not at all distinct; discal stria strongly

impressed, totally impunctate, obsolete at basal third; punctures of the discal

New Mexico (Albuquerque). Mr. H. F. Wickham.

The metasternal process is short and very broad, coarsely reticu-

late, but with the lines very feeble, truncate at apex, very sparsely

pubescent, the mesosternum before it moderate in length, not very

tumid, pubescent at the sides only. The prosternal process is

broad, the terminal setose spines long and conspicuous.

This is the most minute species known to me within our faunal

limits, and is so distinct in all its characters that it cannot be mis-

taken for any other.

S. pusillus Lec.—Proc. Ac. Phil., 1856, p. 17.—Oval, slightly attenuate

nearly as long as the next two together, outer joints of funicle but slightly

more robust, seventh much longer than the eighth, the latter strongly trans-

verse, club rather long and slender, the ninth joint longer than wide, longer

than the tenth and much shorter than the eleventh. Prothorax excessively

discal stria obsolete at basal third, rather deeply impressed, punctate ante-

riorly ; surface with rows of punctures of which the two nearest the suture are

very distinct, but obsolete in basal and apical third, rather deeply impressed

and very narrowly but strongly crescentiform ; the rows thence to the sides

composed of more minute and very feeble punctures, which are not larger or

more distinct, and rather more confused near the sides, except a regular

series just within the extreme lateral bead which is composed of slightly

larger, more closely placed and feebly dilated punctures. Abdomen very

sparsely, feebly punctate and pubescent. Legs slender; posterior tibie

slightly wider at apical third than at apex, spinose, especially externally ;

terminal spurs minute, the tarsi slender, with the basal joint rather more

middle posteriorly; the process is wide, short, much smoother, very

sparsely pubescent and not distinctly punctate; the mesosternum in

front of it very short and feebly tumid, not at all conspicuous. The

prosternal process is very strongly dilated at apex, the setose spines

unusually long.

This minute species is abundant and widely distributed through-

out the Gulf States.

S. modestus n. sp.—Somewhat broadly oval, very feebly narrowed be-

hind the prothorax, polished, rather dark brownish-testaceous above, the legs,

antenne and under surface pale flavo-testaceous. Head extremely obsoletely

and sparsely punctate, not at all reticulate; eyes moderate; antenne rather

slender, third joint nearly as long as the next two together, the fourth shorter

than the fifth, seventh longer than the eighth, the latter slightly transverse,

club rather slender and compact, ninth joint but slightly longer than the

tenth, and but slightly more than one-half as long as the eleventh. Prothorax

nearly as in pusillus. Scutellum two-thirds wider than long. Elytra finely

and distinctly reticulate throughout in transversely wavy broken lines; discal

stria strongly impressed, punctate anteriorly, obsolete at basal third, the punc-

tures of the two rows nearest the suture very strongly impressed, but obsolete

in basal and apical third, the punctures of the remaining rows thence to the

lateral margins very feeble but broad and distinctly crescentiform, becoming

broader in the lateral rows. Abdomen shining, sparsely, coarsely pubescent,

much more densely so toward the middle and apex. Legs rather slender,

moderate in length ; posterior tibie rather wider at apical third than at apex,

having series of spinose sete, more evident along the external edge; terminal

spurs very small, slightly unequal; the corresponding tarsi very slender, but

slightly shorter than the tibize, with the basal joint fully one-half as long as

the second. Length 1.3-1.5 mm.

Texas (Austin).

The post-coxal portion of the mesosternum is not at all defined

posteriorly ; the metasternal process is short and broad, densely

pubescent, the mesosternum in front of it rather long, feebly tumid,

scabrous and rather densely, coarsely pubescent; the prosternal

process is very abruptly, strongly dilated at apex, the terminal

sete very long and conspicuous.

The nature of the elytral punctuation, especially in the lateral

series, the larger size, paler coloration, and more prominent meso-

sternum will readily distinguish this species from pusillus, to which

it is otherwise closely allied. It was taken in considerable abun-

dance.

strongly reticulate, the reticulations rounded and not tending in the least to a

linear arrangement; antenne# moderate, coarsely setose, fourth joint shorter

than the fifth, club rather robust, moderate in length, the eleventh joint but

slightly longer than the ninth. Prothorax more than twice as wide as long ;

base transverse, without a median lobe but slightly sinuate for a short distance

each side of the scutellum; bead very minute ; surface not visibly punctate,

finely reticulate, the reticulations tending to a transverse arrangement. Scu-

tellum ogival, nearly twice as wide as long, transversely reticulate. Elytra

finely and very strongly reticulate over the entire surface, the reticulations

tending to form very broken transverse wavy lines ; punctures of the series

almost completely obsolete although perceptible, scarcely more visible at the

sides, where they become slightly wider but not at all crescentiform: discal

stria feeble, coincident with the suture at the apex, very short, disappearing

in a row of feeble punctures at about the middle. Abdomen strongly reticulate,

sparsely, finely punctate, very sparsely pubescent. Legs moderate, tibize

slender; posterior spurs small, subequal, the corresponding tarsi about two-

thirds as long as the tibie, with the basal joint more than one-half as long as

New Jersey (Cape May).

The metasternal process is very wide, broadly rounded at apex,

the mesosternum in front of it rather short, transverse and but very

slightly tumid; the prosternal process is wide, and the spinules

along its apical margin very short and widely distant. The surface

of the metasternum in the middle anteriorly is extremely sparsely

pubescent, and not visibly punctate.

The dark color and sternal structure will at once distinguish this

small species from nitidus, which it somewhat resembles in elytral

sculpture and punctuation, and the short very feeble discal stria

separates it from every other species of the genus known to me.

It appears, however, to resemble the Mexican Olibrus porrectus

Sharp, which is almost certainly not an Olibrus.

S. convergens n. sp.—Somewhat narrowly oval, very convex, polished,

dark rufo-testaceous throughout, distinctly attenuate behind from the base of

the elytra, the apex narrowly subtruncate and about one-half as wide as the

eyes and base, not at all reticulate; antennz moderate in length, third joint

rather shorter than the next two together, fourth shorter than the fifth, seventh

veloped, ninth and tenth joints equal.in length, more acutely angular on the

anterior side which is more densely pubescent, eleventh nearly as long as the

two preceding. Prothorax rather long, not more than twice as wide as long,

basal lobe very feeble, the marginal bead obsolete. Scutellum very short and

broad, more than twice as wide as long. Elytra excessively minutely and feebly

strigilate, having series of very minute simple punctures which, abruptly, near

the sides, become strongly transverse, confused and feebly crescentiform, the

sculpture also becoming more granulato-reticulate; discal stria deeply im-

pressed, obsolete at basal third. Abdomen sparsely, coarsely pubescent, the

transverse rows near the apices of the segments almost spinose. Legs moderate

in length, rather robust; spurs of posterior tibie slightly robust, moderate in

length, and very slightly unequal; posterior tarsi rather robust, the third

joint rather strongly dilated and bilobed, first joint about two-thirds as long

as the second, the latter spinose beneath and longer than the fifth which is

very slender. Length 2.0 mm,

Florida. Mr. Schwarz.

The metasternal process is very broad and rather long, advancing

almost to the anterior limits of the cox, subtruncate at apex with

the lateral beaded margin very wide, the surface polished, and almost

completely impunctate and glabrous, the mesosternum before it very

short, slightly tumid, glabrous in the middle but scabrous and setose

at the lateral angles. The prosternal process is broad, dilated at apex,

having a fine strong beaded margin throughout the sides and apex,

the sete of the transverse apical series very short but numerous.

This is a decidedly aberrant species, especially in tarsal structure.

It is also peculiar in having the small fovez at the sides of the head

near the eyes quite as well developed as in Phalacrus.

S. attenuatus n. sp.—Narrowly ovoidal, convex; sides of the elytra

gradually convergent from base to apex, the latter narrowly rounded; dark

rufo-testaceous throughout, polished. Head very strongly retractile, polished,

not reticulate, very minutely and sparsely punctate; antenne nearly as in

convergens, the club rather more slender and more symmetrical. Prothorax not

more than twice as wide as long, the sides rather feebly arcuate; basal lobe

almost completely wanting, the marginal bead nearly obsolete; surface not

reticulate, excessively finely, feebly and very sparsely punctate. Scutellum

very short, twice as wide as long. Elytra excessively minutely strigilate in

transverse wavy lines which are obsolete toward suture and base; discal stria

distinct, obsolete at basal third; punctures of the series equal throughout the

width from the suture to the sides, deeply impressed, narrowly and strongly

crescentiform and distinct, except near the base and toward apex where they

become nearly obsolete; intervals each with a single more irregular series of

very feeble and much smaller punctures of the same general character, the

series not confused near the sides. Abdomen finely reticulate, sparsely, coarsely

pubescent. Legs somewhat robust; posterior tibie more arcuate within, rapidly

narrowed toward base; spurs very small, slightly unequal; tarsi slightly

robust, basal joint two-thirds as long as the second. Length 1.6 mm.

New York; Michigan; Texas.

The head is strongly retracted within the prothorax in each of

the single representatives of the above localities. The metasternal

process is rather narrow, short, strongly rounded at apex, and

strongly beaded at the sides, the mesosternum in front of it un-

usually long but almost perfectly flat and not setose, except very

sparsely at the sides. Prosternal process rather wide, extending

rather further than usual beyond the cox, with the free edge

strongly, transversely arcuate, and very acute; the process is very

minutely beaded at the sides, but not at all at apex, where the seti-

form spinules are short, erect and very widely spaced.

This species is quite as aberrant as convergens, but does not at

all resemble it in the structure of the sterna. The post-coxal portion

of the mesosternum is not as long as in some other species, but is

very clearly and abruptly limited throughout by an evenly arcuate

declivous line. The terminal sete of the prosternal process are not

quite as short as in convergens, but are very much more widely

spaced, being only about four in number.

8S. elongatulus n. sp.—Subelongate, convex, polished, black above, the

elytra gradually slightly paler at apex; under surface pale, rufo-testaceous

throughout; sides feebly convergent behind from the base of the elytra. Head

retractile, feebly convex, rather closely but extremely finely punctate ; surface

not reticulate; eyes rather large; antennz slender, the club slender, some-

what compact, attenuate toward vase, the ninth joint rather longer than wide,

longer and narrower than the tenth, eleventh about as long as the two preced-

ing. Prothorax rather elongate, scarcely twice as wide as long ; sides evenly,

distinctly arcuate ; surface polished, not at all reticulate, excessively minutely

punctate, the punctures not very sparse; basal lobe extremely feeble, the

bead fine but distinct near the middle, obsolete laterally. Scutellum small,

nearly twice as wide as long, angulate; sides straight, abruptly arcuate near

the base. lytra rather distinctly more than twice as long as the prothorax ;

sides nearly straight toward base, together somewhat narrowly rounded

behind ; basal stria fine, reflexed along the scutellum, the single discal stria

very coarse and deeply impressed, becoming gradually feebler and punctate

toward base; disk coarsely and strongly reticulate in well-defined transverse

wavy lines, the sculpture becoming abruptly almost obsolete near the base,

having rather distant rows of coarse deeply-impressed rounded punctures,

which are scarcely perceptibly stronger toward the suture, the rows not

attaining the base and becoming gradually obsolete toward the apex, the

punctures of the lateral rows distinct but not dilated, the rows not accom-

panied by impressed lines. Length 1.3 mm.

Florida (Tampa). Mr. Schwarz.

The structure of the under surface agrees quite closely with that

of attenuatus, to which this species. is most unquestionably allied,

but from which it is abundantly distinct in size, coloration, and

punctuation, the punctures of the elytral series being much less

widely spaced and more numerous.

LITOCHRUS Erichs.

This genus, and the two which follow, are distinguished from all

the others of the family by an abrupt and very radical difference in

the structure of the posterior tarsi, for here, instead of the basal

joint being very much shorter than the second, it is correspondingly

longer, and in the present genus is extremely developed.

The four species which are assigned below to Litochrus, possess

the following assemblage of characters, pulchellus being assumed

as the type :—

Ligula short, broad, with a small median tooth at apex, the paraglosse

large, dilated, semimembranous, rather thick and slightly reflexed. Labial

palpi very short and robust, first joint minute, triangular; second oblique,

short, slightly longer than the first, strongly transverse; third longer than

the two preceding together, extremely robust, subquadrate, slightly longer

than wide, strongly compressed and broadly, transversely truncate at apex.

Prosternal process inflexed at apex, not setose. Mesosternum in front of the

metasternal process very short and transverse, not prominent, forming a fine

undilated bead behind the middle coxe. Metasternal process rather long and

wide. Posterior tibie and tarsi very slender, the first joint of the latter much

longer than the entire remainder ; tibial spurs well developed, slender.

The true Litochrus of Erichson agrees with this, according to

description, in the structure of the ligula, but differs greatly in the

labial palpi,’ and the species here assigned to it may possibly have

to be separated. The fact that widely different localities have been

assigned to the genus by its author, renders it almost certain that

several genera have been confounded, more especially as we know

now that there are several distinct genera with elongate basal joint

1 The labial palpi are described by Erichson as having the first joint long,

somewhat longer than the second, the third elongate-ovoidal, which is much

more true of either Litochropus or Ochrolitus, than it is of the American

species of Litochrus. This is, however, a matter which cannot be satisfac-

torily settled until the entire family is monographically revised.

become much more minute and feeble, and confusedly dispersed over the

entire interval, especially between the discal strive; the latter fine but dis-

This species differs conspicuously from the others in coloration,

but the structural characters are nearly alike in all of them, the

punctures in general, and especially the very strongly transverse

crescentic punctures of the elytra, are, however, decidedly most

distinct in the present species.

Florida (Biscayne Bay). Mr. Schwarz.

Remarkably distinct in its intense black color and feeble punc-

tures. The eyes are, as usual, very coarsely faceted, the facets,

however, unusually convex, especially beneath. The metasternal

process is wide and long, extending slightly beyond the cox, the

apex feebly arcuate, the sides parallel, very finely beaded and not

at all incurvate; the mesosternum forms a very thick and even

apical bead. In erucigerus and immaculatus the metasternal pro-

cess is narrower, the sides being distinctly, although feebly, incur-

vate.

rately punctate throughout. Prosternal process moderate in width, the apex

inflexed and unarmed ; metasternal process rather wide, with the sides parallel,

rather long, extending fully to the anterior limits of the cox, broadly, evenly

rounded at apex. Mesosternum in front of the metasternal process forming a

very thick, strongly prominent, feebly scabrous and minutely setose marginal

bead, which becomes fine along the inner side of the coxe, and is dilated

behind the middle acetabula as in Acylomus. Legs slender; posterior tarsi

very slender, cylindrical, nearly as in Litochrus, but with the first joint

scarcely four-fifths as long as the entire remainder; posterior tibial spurs

moderate, very slender, decidedly unequal.

In the structure of the ligula, labial palpi, and the extension of

the mesosternum behind the middle acetabula, this genus differs

very greatly from those species which we consider Litochrus and

represented by pulchellus as a type; the basal joint of the posterior

tarsi is also distinctly shorter, and the third joint of the latter is

very obliquely truncate at apex, the fourth with its ill-defined basal

lobe being inserted at the middle of the truncation.

long as the next two together, outer joints of funicle robust and transverse,

ninth and tenth subequal in length, eleventh as long as the two preceding.

as in Litochrus but more feeble; marginal bead obsolete. Scutellum ogival,

nearly twice as wide as long. lytra entirely polished, without trace of fine

sculpture, having series of long fine transverse scratches, the punctures

entirely obsolete, although each of the fine lines has a very minute recumbent

hair in the middle, the lines feebler toward base and apex, the series so close

that the transverse lines are sometimes continuous laterally ; sutural bead

subapical, excessively fine; discal strize obsolete at basal third, distinct, the

first continuous to the apex, the second coincident with the first at apical

fourth. Abdomen finely, feebly reticulate, sparsely, coarsely pubescent. Legs

moderate in length. Length 1.5-1.7 mm.

North Carolina; District of Columbia.

The posterior tibiz, in the males, are slightly more robust than

in the females, but there does not seem to be any decided sexual

difference in the terminal spurs or tarsi.

The remarkable transverse scratches, which are an extreme modi-

fication of the ordinary type of transversely crescentic punctures,

are peculiar to Litochropus and Ochrolitus, and it is probable that

Litochrus globulus Sharp, should be assigned to the present genus.

142 Coleopterological Notices.

OCHROLITUS Sharp.

This genus is well distinguished from either of those which pre-

cede by the structure of the prosternal process, which is here more

developed, projecting beyond the anterior cox, having the apex

free, with an acute edge which is transversely arcuate.

The two species described below differ generically. I did not

receive the type of tristriatus until a time subsequent to the print-

ing of the table of genera, given on page 91, and had previously

regarded rubens as a typical form of the genus; it is therefore

undesirable, at present, to create a new genus for the latter species,

although this must be done when the family is monographically

revised. The species are very easily distinguishable as follows :—

Prosternal process moderate in width, feebly, longitudinally convex, extending

but slightly beyond the coxe, the apex moderately dilated, very feebly

arcuate, unarmed. Mesosternum not developed behind the middle ace-

tabula. First joint of the posterior tarsi much longer than the next two

combined. Discal strie three in number ............e0 ee EPistriatus

Prosternal process wider and longer, projecting distinctly beyond the CON®,,

flat, spatuliform, the apex very strongly rounded and bearing a series of

five or six long spinose sete. Mesosternum developed as a short arcuate

plate behind the middle acetabula. Basal joint of the posterior tarsi

shorter, subequal in length to the next two together. Discal strive two in

O. tristriatus n. sp.—Oval, very convex, rather wore than one-half

longer than wide, widest near the base of the elytra, the sides thence very

feebly convergent behind ; upper surface shining, dark piceo-rufous, the elytra

slightly opalescent; beneath paler, rufo-testaceous. ead not reticulate, very

finely but distinctly and rather densely punctate; eyes moderate; antenne

long and well developed, second joint small, much shorter than the third, the

latter equal in length to the fourth and but slightly longer than the fifth,

eighth but slightly wider than the seventh, scarcely as wide as long; club

nearly symmetrical, rather loose, as long as the five preceding joints combined,

ninth joint very slightly longer than the tenth and fully two-thirds as long as

the eleventh. Prothorax large, but slightly more than twice as wide as long,

the base very feebly incurvate between the basal angles, the basal lobe rather

wide but excessively feeble, the bead completely obsolete; surface not reticu-

late, extremely minutely and moderately sparsely punctate, the fine hairs

unusually long and distinct. Scutellum triangular, nearly twice as wide as

long. lytra scarcely more than twice as long as the prothorax, the apex

distinct hairs, the latter not being very definitely arranged ; each elytron with

three distinct discal striae, vanishing at about basal third, and converging

toward the apex, the outer two slightly abbreviated ; sutural bead fine, but

distinct toward the apex. Legs rather robust; posterior tibie cylindrical,

narrowed in basal third, almost transversely truncate, the spurs long and

very unequal, the corresponding tarsi long, cylindrical, the basal joint one-

third longer than the next two together. Metasternui coarsely and strongly

punctate toward the middle. Length 2.1 mm.

Florida (Key West). Mr. Schwarz.

The metasternal process is narrow and rather short, the meso-

sternum before it forming a rather long gradually declivous piece,

feebly enveloping the cox at the sides,—almost exactly as in Lito-

librus—and not,developed behind the middle acetabula, except as a

fine marginal bead. The prosternal process is finely beaded at the

sides but not at the free acute and feebly arcuate apex, the latter

being also devoid of true spinose set.

There can be but little doubt that this species is a complete repre-

sentative of Ochrolitus, but it is also certain, on comparison with

the carefully drawn figure of O. optatus Sharp, that it cannot be

identical with that species. In the present form the transverse

scratches are very strong and extend throughout the elytral disk,

except very near the base.

This is a very distinct species which appears to be rather rare;

144 Coleopterological Notices.

I have seen three specimens. The sete of the prosternal process

are not erect as in the Stilbide genera, but perfectly porrected. The

metasternal process is rather long, moderate in width, projecting

almost to the anterior limits of the coxw, the apex truncate, the

mesosternum before it abruptly declivous and not in the least

prominent.

CORYLOPHID #.

JENIGMATICUM Matth.

This singular genus was described by me from some Californian

specimens, before the appearance of Mr. Matthews’ description in

the Biologia Centrali-Americana, but I was somewhat at a loss

where to place it, hesitating between the Corylophide and Latridi-

ide.

The following species occurs in great abundance near San Fran-

cisco, in moist places among the roots of grasses, and I have also

shaken it from small shrubs in the vicinity of Oakland.

AE. californicum n. sp.—Form rather slender, dark piceous-brown,

noderately shining, but without trace of metallic lustre; pubescence cinere-

ous. Head small, subtriangular; eyes rather large, at the base, convex,

coarsely faceted ; front emarginate at each side before the eyes, feebly convex,

finely, feebly granulose, very finely, feebly, sparsely punctate, each puncture

bearing a small subrecumbent hair. Prothorax two and one-half times as wide

as the head, scarcely one-third wider than long, widest at the middle; sides

broadly, evenly rounded in the apical half, feebly convergent, straight and

feebly, minutely serrulate thence to the basal angles, which are slightly obtuse

but not at all rounded ; apex and base broadly, evenly and feebly arcuate, the

latter distinctly the wider, disk feebly, evenly convex, finely subgranulose,

slightly alutaceous, rather coarsely, deeply, but somewhat sparsely punctate,

finely sparsely pubescent. Scutellum moderate, very strongly transverse,

smooth and polished. lytra one-fifth longer than wide, widest near the

middle, one-fifth wider and two-thirds longer than the prothorax ; sides

broadly arcuate; apex angularly emarginate, exterior angles rounded; disk

feebly convex, shining, not distinctly alutaceous, very feebly and finely reti-

culate, finely, feebly and sparsely punctate; punctures rather obsolete, not

arranged in well-defined order; pubescence very fine and sparse. Legs,

antenne and under surface, except the abdomen, much paler, brownish-testa-

ceous, the latter piceous-black. Length 0.8-0.9 mm.

California (San Mateo and Alameda Cos.).

Differs from the Central American ptilioides Matth. in its larger

size, more elongate prothorax, and shining elytra and scutellum.

Coleopterological Notices. 145

The fifth antennal joint in pfilioides is represented on the plate as

being slightly elongate; it is correspondingly transverse in the pre-

sent species, and the joint immediately before the club is strongly

transverse and not elongate as in ptilioides. The sutural stria is

feeble and continuous with the basal stria."

BYRRHID#.

LIMNICHUS Latr.

The species of this genus, although but moderately numerous in

the United States, appear to be much more abundant and diversified

in structure than their European congeners. Our species have

never been fully described, and have been somewhat neglected by

systematists. The table given by LeConte (Bull. U.S. Geol. Surv.,

V, p. 515), bears evidence of insufficient observation, and I have

not found it of very great service in identifying the species, which

in reality are well differentiated. They may be divided as follows

into four subgeneric groups, which are perhaps of still greater value.

These groups are all distinct from the representatives of the palz-

arctic fauna, there being generally no trace whatever of the antennal

groove on the superior surface of the head which is such a singular

character of Limnichus proper. In all of our subgenera the antenne

are perfectly free in repose, although generally pressed closely against

the head, and between its surface and the projecting anterior margin

of the prothorax. In the first group (Eulimnichus), the last vestige

of the groove is visible, being indicated by a minute carina border-

ing the sides of the head above the eye, but it can be of no use as

a shelter for the antenne in repose :—

Pubescence in a single system, rather sparsely distributed, subrecumbent,

robust and aciculate.

Head Jongitudinally rugulose; basal joint of antenne in great part con-

cealed by the acute sides of the front, the emarginations at the extremi-

ties of the epistomal suture small. Prosternum grooved; hypomera flat,

not impressed at the inner angle, having a wide prominent polished bead

along the inner margin; margin of the crural excavation acute and

cariniform ; acute outer edge minutely and abruptly reflexed at apex.

! Dr. Sharp, who has been kind enough to compare a specimen of this species

with the type of ptilioides in the British Museum, writes me that, although the

light at the time was very poor, he has no doubt of the distinctness of califor-

nicum.

The minute reticulation or granulation, especially visible at the

sides of the pronotum and on the hypomera and abdomen of

groups I, III, and IV, is totally obsolete in group II, and consti-

tutes an important differential character of this section of the genus.

As a generic character, it should be stated that the epipleure are,

near the apex, deeply grooved; this is more evident in the first three

groups, and becomes very feeble or nearly obsolete in group IV.

The species may be distinguished as follows :—

Michigan (Detroit). Mr. Schwarz. |

The form described by LeConte as olivaceus has given rise to

more or less divergence of opinion. Henshaw in his list of the

species described by J. L. LeConte (p. 230), states that it is a valid

species. Dr. LeConte in his most recently published table of the

genus (Bull. U.S. Geol. Surv., V, 1879, p. 515) unites it in

synonymy with punctatus, and Henshaw in his check-list of North

American Coleoptera, appears to coincide with this opinion. I have

personally examined the specimen in the cabinet of LeConte which

bears the type label, and find that it is absolutely identical with the

type of punctatus, the punctuation being fully as dense as in that

species. Schwarz has taken in abundance at Detroit, Mich., a

species—described above—which is allied to, but certainly distinct

from, punctatus, having the elytral punctuation decidedly sparser

but not quite as coarse; it is the opinion of Mr. Schwarz that this

is the true olivaceus.

Coleopterological Notices. 155

I leave this subject, therefore, with the opinion that the specimen

labeled olivaceus in the cabinet of LeConte, is not the original

type, and further that the specimens from Detroit may fairly be

assumed to represent that species; the latter seems, at least, a

better course to pursue than to give this undoubtedly valid species

a new name, based upon an uncertainty of identification.

This species is distinguished by its remarkably sparse and fine

punctuation of the prothorax, above and beneath, for this section

of the genus, and contrasting remarkably with the very coarse

dense punctuation of the elytra. The abdomen is much more

sparsely punctate than in any of the other species of this subgenus.

For the present this species may be considered the type of a sub-

genus of Limnichus, but it is almost unquestionably of higher value,

the unimpressed prosternum, long antenne, and large equilateral

scutellum distinguishing it at once from any of the others. If it

is considered generically distinct, however, the lutrochinus group

must also be separated on other, but equally decisive characters.

In its entirely impunctate abdomen this species differs from any

other of the subgenus; it somewhat resembles ovatus, but differs

in its more elongate form and in its coarser elytral punctures, these

heing about twice as large as in that species. The longer hairs of

the elytra in ovatus are longer than in naviculatus, and the short

appressed ones much sparser. In ovatus there is no trace of macu-

lation, whereas in the present species the pubescence is paler at

three indefinite lateral spots on each elytron, giving, under extremely

low power, the appearance of three imperfect transverse fasciz ; in

the former the intermediate tarsi are nearly two-thirds as long as

the tibiz.

The large hairs of the elytra are but slightly longer than the fine

short subappressed ones, and are entirely inconspicuous; there are,

however, on each elytron four series of long erect white sete which

are very widely spaced; these contrast strongly with the general

vestiture, when viewed under light coming horizontally along the

axis of the body and from the front. I have not noticed these sete

in any other species, although they probably exist, and are simply

more prominent in the present case because of the extraordinary

shortness of the general pubescence. This last character will easily

distinguish serdatus from ovatus. The elytral pubescence is fulvous

in color and entirely devoid of maculation.

The rather shining surface, black color and coarser, very dense

abdominal punctuation will render the identification of this species

very easy. The series of longer coarser sete on the elytra, men-

tioned under seriatus, are represented here by the marginal series

only, the others being not distinctly traceable.

PHYSEMUS Lec.

Regarding the relationship of the three genera Bothriophorus,

Physemus and Ditaphrus, the following observations may prove

interesting.

In the remarks appended to the original description of Ditaphrus

(Bull. Cal. Acad. Sci., II, pp. 250-253), the reasons were given for

the separation of the genus from Physemus; they were based solely

upon the original description of the latter as given by Dr. LeConte.

After the publication of Ditaphrus the suspicion of its identity with

Physemus continued to grow upon me, until I determined to dis-

cover the truth if possible by actual observation. I accordingly

made a journey at considerable expense from San Francisco to

Yuma, incidentally for the purpose of collecting Coleoptera, but

especially to rediscover the species Physemus minutus. Knowing

the haunts of Ditaphrus scymnoides in Texas, I did not have to

search long before finding LeConte’s species in numbers, moving

slowly over the surface of moist adobe mud, under débris of fallen

leaves. An examination at once revealed the fact—as I had antici-

pated—that the two genera are identical in every point of structure,

and that the species also are the same, although presenting very

slight differences in size and vestiture.

Wishing to carry the investigation a step further I have procured

from M. Desbrochers des Loges, a specimen of the European Both-

riophorus Muls., and find on examination that, while resembling

Physemus very closely, it differs decidedly in antennal structure.

Coleopterological Notices. 161

If the student will have before him the figure of the antenna of

Physemus (1. c. plate), he can more readily appreciate the differences

as indicated in the following description :—

First six joints somewhat similar to the same in Physemus. Seventh joint

slender, cylindrical, nearly twice as long as wide; eighth just visibly wider

than the seventh and one-half as long, triangular, the vertex of the angle

directed anteriorly, the posterior side straight; ninth triangular, transverse,

the angle on the anterior side, the posterior side nearly straight, scarcely

longer and one-half wider than the eighth ; tenth almost evenly obtrapezoidal,

scarcely longer than the ninth but distinctly wider, two-thirds wider than

long, closely joined to the eleventh throughout the width; eleventh ovoidal,

pointed, slightly wider than the tenth, two-thirds longer than wide, slightly

longer than the two preceding joints combined and more densely pubescent.

It will be seen, therefore, that the two genera are quite distinct

in antennal structure, the one having a two-jointed, and the other

a three-jointed club.

The species—B. atomus Muls.—is somewhat smaller and more

finely and very much more feebly punctate than Physemus minu-

tus Lec.

the posterior prolongation of deep grooves beneath the eyes. Prothorax fitted

to the elytra throughout the width of the latter, with the basal angles acute

and slightly produced posteriorly.

This genus was founded by LeConte upon the Californian repre-

sentative 7. Crotchii, which is more slender than the present, more

finely and much more densely punctate and pubescent, the hairs

being somewhat confusedly matted as in Heterocerus. The above

diaghosis was drawn from the Texan species which seems to be

A sexual character, which seems to have escaped observation,

exists in perhaps its greatest development in quercus. It will be

seen that in this species, the posterior tarsi of the female are much

shorter than in the male. In oregonensis the same condition holds,

but to a less-marked degree, and in Agassiz the character completely

disappears, the tarsi in both male and female being very long and

slender, with the fourth joint twice as long as wide. The type of

californicus is a female, and, as the posterior tarsi are extremely

short, relatively more abbreviated even than in the female of quer-

cus, with the fourth joint fully as wide as long, it is probable that

the male, also, has a shorter tarsus than Agassiz, and that the

species is to be associated with quercus and oregonensis, rather

than with Agassi.’

Through the kindness of Mr. J. J. Rivers of Berkeley, California,

who has made the study of this genus somewhat of a specialty, I

have been permitted to examine a larger series than has been

hitherto available to me, and find that there are several species

similar to Agassi in having the mandibles small and inconspicu-

ous in the males, and the hind tarsi nearly as long as the tibie.

The series alluded to affords sufficient material for a tolerably com-

plete study, and consists of twelve specimens of Agassiz, three of

pacificus, and two of parvicollis. These three species may be

defined as follows, the characters given referring to the male only :—

Sides of the prothorax—viewed vertically—distinctly subangulate.

Pronotum finely, densely punctate; antennal club much longer than the

funicle, the last joint strongly asymmetric, the longest dimension being

in a direction oblique to the axis of the club, and very much exceeding

California.

Readily distinguished from Agassii and pacificus by the pale

color, small prothorax which is here much narrower than the elytra,

and by the great relative length of the latter. The type is a male;

the antennal club being relatively very much shorter than in either

of the species mentioned. In Agassi the funicle is three-fifths as

This species is easily distinguished from Agassii by its very

sparse punctuation and form of the prothorax, the sides of the

latter being much more broadly rounded, when viewed vertically,

than in Agassiz, although when viewed obliquely they are sub-

angulate.

Clypeus rather prolonged, concave; apex with a small median notch and

feebly bidentate, strongly inflexed for a great distance beneath, the labrum

entirely connate and obsolete, not visible except as a minute reflexion of the

infraclypeal surface. Mentum minute, very narrow, elongate, nearly flat.

Maxille large, the palpi rather large; basal joint small; second and third

subequal, longer than wide; fourth as long as the preceding together, wider,

elongate-oval, with a broad shallow groove on the outer face throughout the

length, the apex with a minute oval impressed area. Labial palpi very

minute. Eyes large; inferior portion much larger than the upper, separated

beneath by much less than their own width. Antenne nine-jointed; basal

joint as long as the next three together, slender at base, strongly inflated

toward apex, the apical margin fringed with a single row of long erect sete;

second wider than long, narrower than the first, strongly narrowed at base;

third to fifth subequal in length, longer than wide, subcylindrical and sub-

anchylosed ; sixth very short, strongly transverse, slightly wider; seventh to

ninth forming a very large club, twice as long as the stem—measured in a

direction perpendicular thereto—strongly arcuate toward apex, and, in shape

and relationship with the stem, exactly as in Polyphylla. Vertex with a fine

longitudinal ridge over each eye; clypeal suture obsolete except near the sides

where it is fine and transverse. Anterior margin of the pronotum with a broad

flat bead throughout; posterior margin with a very much finer one, which

_ becomes abruptly very fine in the middle and also laterally. Scutellum rather

large, ogival. Elytra projecting well behind and partially concealing the

pygidium. Anterior coxe large, transverse, strongly conical and prominent

internally ; prosternum very short before them, the anterior margin broadly

bisinuate between the strongly advanced and acute anterior angles of the

pronotum ; hypomera rather wide, nearly flat and almost horizontal; femora

large, broad, flattened, posterior very large; anterior tibiae with a small acute

internal spur near the apex, two external obtuse teeth, and a prolonged apical

process which is slightly dilated toward apex; middle and posterior tibie

robust, festooned in the middle with an oblique girdle of spinules, obliquely

truncate and dilated at apex, with a fringe of short robust spinules, and two

long terminal spurs; tarsi very long and slender, twice as long as the tibie ;

joints very long, slender and cylindrical; basal joint longest; claws very

slender, long, finely acuminate, very feebly arcuate, equal and very minutely

carinate internally at base. Metasternum very obliquely truncate at the sides

behind, in the middle longer than the abdomen; episterna short and broad.

Abdomen extremely short in the middle, broad, consisting of five segments ;

sutures distinct throughout the width ; first segment almost completely covered

by the very large posterior coxew. Pygidium moderate, about as long as wide,

feebly convex, rounded at apex, very feebly and inwardly oblique.

The very long slender tarsi and nine-jointed antenna seem to

point at first to a relationship with Macrodactylus, but the very

large mentum, feebly inflexed clypeus and abdominal structure of

the latter prohibit any such association. From the Sericini it differs

in its very minute elongate mentum, this organ in that group being

large and transverse. From the Dichelonychini it differs in its

minute mentum and obsolete labrum, and from all these in the form

of the labial palpi. The latter are extremely minute, scarcely visi-

ble, and closely approximate, the two basal joints very small, sub-

globular, the third longer than the first two together, elongate-oval.

In the genus Podolasia the elypeus is formed nearly as in Acoma,

but is slightly more developed above, and inflexed for a much shorter

distance beneath. The labial palpi are large and very evident; the

antenne are nine-jointed, with a small robust three-jointed club, and

with the second joint large and globular; the anterior tibie are

devoid of internal spine, and the long apical process is acute and

strongly excurvate. The claws are long and slender, with a small

longitudinal carina internally at base, but not properly toothed.

The first four abdominal segments are connate, the sutures exces-

sively feeble in the middle, but not entirely obliterated, the fourth

suture wide and membranous.

I think, therefore, that this interesting genus may be placed for

the present near Podolasia, but with the assumption that it consti-

tutes a connecting bond with some other group in its almost per-

fectly free abdominal segments, extremely minute labial palpi, and

greatly developed antennal club of the male.

In Chnaunanthus the ventral sutures are absolutely obliterated in

the middle, and this genus is therefore a more highly specialized

representative of the group Oncerini, than either Podolasia or

Acoma. e

A. brunnea n. sp.—Form oblong, the sides nearly parallel, moderately

convex, dark reddish-brown throughout; head and prothorax almost glabrous,

but rather densely fimbriate with long erect hairs at the sides; elytra sparsely

clothed with rather long erect hairs, which are longer and more conspicuous

at the sides; under surface bristling with long slender sparsely placed hairs,

especially conspicuous on the fimbriate femora. Head coarsely, very densely

and deeply rugoso-punctate, the clypeus, which is nearly, as long as the

remainder of the head, ‘coarsely, deeply and sparsely punctate. Prothorax

four-fifths wider than long; sides strongly rounded just behind the middle,

thence convergent and feebly sinuate to the acute apical angles, broadly

rounded to tlie base, the basal angles being broadly rounded and obsolete ;

opposite the scutellum; apex broadly emarginate, bottom of emargination

broadly bisinuate; disk moderately convex, polished, feebly impressed along

the median line except near base and apex, finely, sparsely punctate; punc-

ttires:entirely wanting in a broad median line, and also along the basal mar-

gin. Scutellum almost impunctate. Elytra widest in the middlé& slightly

longer than wide, very slightly wider than the prothorax; sides parallel,

feebly arcuate, together broadly, obtusely rounded behind; humeri slightly

prominent; disk feebly convex, strongly so at the sides, finely, feebly and

unevenly striate; strie more approximate and very much confused at the

sides, where the surface is distinctly rugulose ; strie very finely and approxi-

mately punctate; intervals each with a very uneven single line of larger, more

distant punctures. Length 5.0-5.5 mm.

POLYPHYLLA Harris.

The American species of this genus appear to agree very well

with the European, and differ principally in their shorter, more

robust legs. The following species belongs near decemlineata, and

may be at once interpolated in the table given by Dr. Horn (Trans.

Am. Ent. Soe., LX, p. 73).

P.speciosa n. sp.—Elongate-oval, convex; prothorax trivittate; lateral

vitte interrupted.

Female.—Head much wider than long; clypeus two and one-half times as

wide as long; sides parallel, feebly arcuate; apex broadly and very feebly

bisinuate, the lateral angles acute, more prominent and more strongly re-

flexed ; front coarsely and very densely punctate, rather sparsely clothed with

short erect hairs, and squamose with large pointed scales toward the eyes

and along the margins of the clypeus; antenne rather robust; basal joint

pyriform, robust, as long as the next two together; second and third elongate,

the latter much the longer, fourth obconical, slightly produced inwardly at

apex, feebly transverse; club feebly arcuate, six-jointed, first narrower and

more acuminate than the others, pointed, and but little more than one-half as

long, remaining joints equal in length and nearly as long as the entire stem

including the basal joint. Prothorax widest just behind the middle, narrowed

rather rapidly thence to the apex, the latter about two-thirds as wide as the

base, broadly emarginate and feebly bisinuate ; base broadly arcuate, more

strongly so in the middle; sides subangulate, angle narrowly rounded, thence

just visibly arcuate to the apical angles, and extremely feebly sinuate to the

base, broadly and very feebly subcrenulate throughout ; basal angles obtuse,

not at all rounded; disk convex, with a very small feeble impression near

each lateral edge at the middle of the length; vitta white, very dense, the

lateral interrupted anteriorly, remainder sparsely covered with large elongate

pointed yellow scales, which are denser near the basal margin except in the

middle; surface anteriorly with a very few short erect hairs; punctures large,

shallow, round and variolate, rather densely but unevenly distributed, each

enclosing a seale. Scutellum broadly parabolic, vittate. lytra three-fifths

longer than wide, in the middle one-third wider than the prothorax ; sides

parallel and feebly arcuate, subtruncate behind; humeri slightly tumid ;

apical umbones large and feeble; each elytron with three broad dense white

vitte, and a fourth very narrow and interrupted between the second and

third from the suture ; third vitta abruptly terminating near the apex, feebly

and evenly arcuate throughout, first and second meeting on the apical umbo,

the first irregular toward base; suture narrowly vittate, the vitta continuing

to the apex; intermediate surface finely, sparsely punctate, and covered

sparsely with moderate pointed yellow scales. Pygidiwm slightly wider than

long, triangular; sides equally arcuate; surface feebly convex, slightly im-

pressed at the sides, sparsely clothed with elongate whitish scales which are

dense along the base, and much sparser in a very narrow median line; surface

also very sparsely and finely pubescent. Abdomen with small robust whitish

scales, much denser along the apical margins of the segments, and also with

very sparse erect pubescence. Length 36.0 mm.

Colorado (exact locality unknown—?); New Mexico—%.

This fine species is easily distinguishable by its antennal structure

from any other in the genus. The last joint of the maxillary palpi

is very feebly lunate, and is pointed at apex. The anterior tibize

are robust, the outer teeth strong, the one nearest the base very

broad, obtuse, and feebly developed." ‘

received a short time since from Central America. The description refers to

the female. F

P. concurrens n. sp.—Form nearly as in decemlineata, pale brownish-

rufous. Clypeus truncate, broadly arcuate in the middle; angles right, not

rounded, but also not prominent, its surface feebly and very narrowly reflexed

at the apical margin, having a few widely scattered, coarse, squamigerous

punctures ; front immediately behind the suture abruptly, coarsely, extremely

densely and deeply punctate, the punctures in mutual contact, the occiput

again abruptly totally impunctate ; antennz moderate, club as long as joints

two to four combined; sixth joint rather less than one-half as Jong as the

remainder, which are equal. Prothorax nearly as in decemlineata, but very

much more sparsely punctate, the median line very deeply impressed, and the

vittee narrow; scales large and robust. Scutellum polished, with a narrow

median vitta. lytra with ten very narrow, densely squamose vitte, the

second from the lateral margin long, extending to apical third, but very widely

interrupted ; intervals extremely sparsely squamose, the scales smaller and

narrower than those of the vitte. Length 25.0 mm.; width 11.0 mm.

Honduras. (One specimen.)

Although resembling decemlineata, this species is smaller, less robust, and

differs greatly in the form of the pygidium, which is slightly longer than wide,

transversely convex, and extremely sparsely squamose, a narrow median line

entirely glabrous. The anterior tibie are tridentate, the basal tooth very

broad and feebly developed. The front and vertex in this species, and also

in speciosa, are very much more densely and coarsely punctate than in decem-

lineata, where the punctures are separated by their own widths. All compari-

sons have been drawn from the female, which is the more constant sex.

THYCE Lec.

The single species, which has been regarded as the type of this

genus, has hitherto been represented by a single female, and the

recent discovery of the male by Mr. Dunn at El Paso, Texas, indi-

cates the absence of generic difference between it and most of the

Californian species separated as Plectrodes.1. The structure of the

anterior cox is identical, and the teeth of the tarsal claws are quite

plainly unequal, to fully as great a degree in fact in 7. squamicollis,

as in many of the recognized species of Plectrodes. Our species

may be separated as follows, the characters referring to the males :—

Fourth joint of the maxillary palpi one-third as long as the antennal club.?

& .

Carpenteri

Fourth joint three-fifths as long as the antennal club; elytra nearly glabrous.

\ squamicollis

Fourth joint three-fourths as long as the antennal club.

Fourth joint A thirds ener than the ntenal Shins ee Marfordi

In Carpenteri and also in Plectrodes pubescens the excavated

groove in the fourth palpi joint is narrow, shallow and feeble, and

is much shorter than the joint; in the remainder it is narrow, very

deep, and extends throughout the length.

The females are much less abundant than the males, and differ

considerably. The fourth palpal joint is small and more uniform

in size with reference to the antennal club, and, although impressed

externally, the groove is shallow and only partial, even in the

1 The genus Plectrodes is represented only by the original P. pubescens of

Horn. In this species the anterior coxe do not differ in form from the same

members in Thyce, but the abdominal segments are much shorter, and are

almost completely free, requiring but slight force to break them asunder, In

all the other species the ventral segments are long and connate, to absolutely

the same degree as in Thyce squamicollis, being indicated only by feebly im-

pressed lines. The genus Plectrodes should therefore be placed in the Melo-

lonthini, where it will constitute one of the transitions to the Macrophyllini.

females of such strongly developed forms as pulverea and Har-

fordi. The antennal club is much shorter, more compact and oval.

The anterior tibiz are stouter and with more strongly developed

external teeth. The vestiture is very much shorter, finer, and

sparser, so that the general color is darker.

The species of Thyce are nocturnal, being abundantly attracted

by bright lights at certain seasons of the year.

T. squamicollis Lec.—The female of this species is much larger

than the male, but is almost precisely similar in vestiture. The

pronotum in both sexes is very sparsely clothed with small, closely

recumbent, squamiform hairs which are slightly denser along a

narrow median line, as is usual throughout the genus; the lateral

vittee are, however, not definite. The name is therefore somewhat

inappropriate. In the male the antennal club is nearly three-fourths

as long as the stem, and in the female only one-half as long as the

latter, oval and more compact.

Although the upper surface is more than usually piahrone: the

long dense silken pubescence of the under surface is as well developed

as in any other species.

T. pulverea n. sp.—Form elongate-oval, convex; elytra and abdomen

dark reddish-brown; head and prothorax darker, piceous, the latter clothed

moderately densely with small robust recumbent hairs, and longer erect pubes-

cence; elytra and abdomen very densely covered with minute, recumbent,

squamiform hairs; remainder of the under surface with long very dense

silky pubescence ; mesosternal parapleure, hypomera, and exposed surface of

maxille devoid of long erect pubescence, but having whiter, dense and recum-

bent, squamiform hairs, a small indefinite spot at the sides of each abdominal

segment also whiter and denser, remaining vestiture cinereous. Head wider

than long; clypeus concave, truncate and very feebly sinuate in the middle,

the angles slightly rounded, the base very slightly narrower; antennal club

as long as the stem; last joint of the maxillary palpus nearly one-half longer

than the preceding together, and fully three-fourths as long as the antennal

club, rather robust, apex oblique but not deflexed and with a small circular

truncation, the groove very deep, widening toward base, entire. Prothorax

one-half wider than long; sides broadly angulate, the angles rounded; basal

angles obtuse and rounded, apical obtuse but not rounded ; apex very feebly

emarginate, one-half as wide as the base, the latter broadly angulate, the

angle broadly rounded; disk convex, finely, feebly and densely punctate.

Scutellum white, more densely pubescent. lytra nearly one-half longer than

wide, widest near the middle, nearly one-third wider than the prothorax;

sides very feebly arcuate; apex broadly sinuate; humeri slightly tumid;

apical umbones very feeble ; disk with the most feeble and indefinite traces of

fine coste, very finely, feebly and densely punctate. Pygidium one-third wider

than long, feebly convex, very minutely and densely punctate and pubescent..

Legs moderate; femora fringed with fine erect pubescence, the flat surfaces

with very small, recumbent, squamiform hairs not very densely placed; tarsi

as long as the tibiz ; claws arcuate, finely attenuate; tooth of anterior claw

of anterior tarsi erect, near the base, slightly arcuate, stout and scarcely one-

third as long as the remainder ; tooth of the posterior claw, less than one-half

as large, projecting but slightly above the basal carina; proportions in the

other claws nearly similar, the tooth of the posterior claw of the hind tarsi,

on its outer edge, nearly one-fifth the internal length of the remaining portion ;

corresponding ratio of the anterior claw one-third. Length 22.0 mm.

California (Los Angeles Co.).

The diagnoses here given are taken from the male; in the female

of the present species the tarsal claws are rather smaller, the teeth

more nearly equal, the greatest difference being in those of the

anterior tarsi, the posterior being almost absolutely equal.

In Thyce the fourth palpal joint is received at base in a broad

excavation in the apex of the robust transverse third joint, and the

latter in turn is similarly connected with the second.

The proportional length of the fourth palpal joint in pulverea is

the same as that given for palpalis, but the two species can be dis-

tinguished by the apparently denser pubescence of pulverea, by

the more robust palpal joint in which the groove, according to the

figure given by Dr. Horn, is differently shaped, and by the claws

of the posterior tarsi, in which the teeth are said to be very nearly

equal in palpalis (Trans. Am. Ent. Soc., VIII, p. 147).

NT. fossiger n. sp.—Form rather broadly oval, convex, castaneous; head

and prothorax piceous; vestiture throughout nearly as in pulverea, but

slightly coarser, and with the erect hairs of the pronotum decidedly longer.

Head small, wider than long; clypeus concave, truncate; angles narrowly

rounded ; sides parallel, strongly arcuate ; antennal club slightly shorter than

the stem and but very slightly longer than the fourth palpal joint, the latter

elongate, rather slender, the apex distinctly deflexed, and with the usual

minute circular truncation, one-third longer than the three preceding together ;

external groove entire, very narrow and deep, slightly enlarged near the base,

and again much more feebly so near the apex. Prothorax two-thirds wider

than long; sides laterally strongly angulate, the angle rounded; sides very

feebly sinuate anteriorly, feebly arcuate toward base and nearly coarctate with

the latter, the basal angles being very obtuse and broadly rounded; apical

angles right, not rounded ; apex very feebly emarginate, one-half as wide as

the base, the latter broadly, feebly angulate, the angle broadly rounded; disk

convex, even, finely, feebly and densely punctate. Llytra two-fifths longer

than wide and two-fifths wider than the prothorax; sides feebly arcuate ;

apex broadly angularly emarginate; humeri very feebly tumid; disk with

very feeble traces of coste, very minutely, feebly and densely punctate.

Pygidium one-third wider than long, feebly convex, punctured, and very

densely pubescent like the elytra. Legs moderate; tarsi as long as the tibie ;

claws nearly as in pulverea. Length 20.0 mm.

California (Los Angeles Co.).

This species is closely allied to the last, but differs in its shorter,

more robust and flattened form, its shorter, more transverse pro-

- thorax with more angulate sides, which are more rapidly convergent

toward base when viewed vertically, and in the structure of the

antennz and palpi. The pubescence of the elytra is more densely

placed, and the pygidium more nearly vertical.

T. Harfordi n. sp.—Oval, convex, piceous-black throughout; vestiture

yellowish-cinereous ; silky hairs of under surface very long and dense ; abdomen

moderately densely covered with small robust recumbent hairs, each segment

with a paler spot of denser pubescence at the side near the apex; maxille,

hypomera, mesosternal parapleure, and metasternal epimera whiter and with

short stout recumbent pubescence; vestiture of the elytra dense, the hairs

robust, recumbent and rather long, sparser on the pronotum, the fine erect

hairs of the latter long, dense and conspicuous. Head small, but very

slightly wider than long ; clypeus concave, broadly, feebly sinuate, the angles

narrowly rounded and the sides parallel and feebly arcuate; antennal club

robust, oval, much shorter than the stem and scarcely more than two-thirds

as long as the fourth palpal joint; the latter greatly developed, more than one-

half longer than the preceding joints together, elongate, and but moderately

robust when viewed laterally, with the lower edge straight, the upper broadly

arcuate, the apex scalpellate, the lower point of the apex not deflexed, and

with an exceedingly minute circular truncation, having externally, an entire

groove which is wide, elongate, elliptical, and extending fully one-half through

the joint. Prothorar two-thirds wider than long; sides rather strongly angu-

late, the angle rounded; sides near it straight; basal angles obtuse and

moderately rounded; apex very feebly emarginate, scarcely one-half as wide

as the base, the latter broadly and rather strongly angulate, the angle broadly

rounded ; disk convex, very narrowly and feebly impressed along the median

line, rather finely, feebly and densely punctate. Scutellum with a very fine

subdenuded median line. L£lytra two-fifths longer than wide and uearly two-

fifths wider than the prothorax, with very feeble traces of broad coste, together

broadly, angularly emarginate at apex when viewed longitudinally; sides

parallel and feebly arcuate; disk minutely, feebly and densely punctate. Legs

moderate; tarsi about as long as the tibie. Length 19.0-20.0 mm.

DINACOMA on. gen. (Melolonthini).

Clypeus concave, parallel, subtruncate. Mentum moderate, subquadrate,

concave. Maxille moderate, the palpi well developed ; first joint very small,

narrow, obconical; second and third longer than wide, the former the longer,

both obconical and obliquely truncate; fourth slightly shorter than the pre-

ceding three together, pointed, deeply impressed or excavated on its outer face.

Labial palpi very small; third joint ovoidal, obtusely acuminate, as long as

the two preceding together. Labrum short, transverse, free, impressed in the

middle. Antenne ten-jointed; middle joints of stem subanchylosed, short ;

club three-jointed, very long and arcuate in the males. Anterior cox trans-

verse, but slightly prominent. Metasternal episterna moderate in width.

Abdominal segments connate, the sutures fine but not entirely obliterated,

rendered distinct by the disposition .of the vestiture. Metasternum well

developed. Legs rather short and slender; tarsi short, the posterior much

shorter than the tibie ; claws moderate, evenly and strongly arcuate, toothed

near the base, the teeth distinctly unequal.

The above characters indicate a genus intermediate in many

characters between Polyphylla and Thyce. It is founded upon

Thyce marginata Casey (Bull. Cal. Acad. Sci., II, p. 39). The

deep excavation of the fourth palpal joint, which is present in this

genus in common with Thyce, is by no means confined to this

group of genera, as it is a common character in Diplotaxis, although

generally less developed.

The characters agreeing with Thyce, reside in the structure of

the palpi and tarsal claws, and those which ally it most directly

with Polyphylla, are found in the greatly developed male antennal

club, and the short tarsi.

California (Mojave Desert, Kern Co.).

This species is quite distinct from any of the others; the pubes-

cence is long and somewhat coarse, evenly distributed over the

elytra, a little shorter, sparser and coarser than in rotundus, and

distinctly shorter, more matted and slightly coarser than in ventri-

cosus; the latter is larger and much more minutely punctate.

cate; punctures of outer face of mandibles coarse, deep and dense, polygonally

crowded. Prothorax very strongly transverse, broadly, very feebly emarginate

in circular arc at apex; lateral edges completely obsolete and broadly rounded,

the apical angles alone acute and prominent; disk polished, very finely and

sparsely punctate in the middle, abruptly coarsely, deeply and very densely

so at the sides, the punctures mutually contiguous. Elytra subglobose, very

strongly convex, rather coarsely, densely and evenly punctate throughout the

disk, the punctures separated generally by rather more than their own diame-

ters. Length 5.5 mm.

A very interesting form, quite isolated by reason of its small

USECHUS Mots.

Two species of this genus are now known; they may be dis-

tinguished as follows :—

Median impressed area of pronotum fusiform, entire, more or less coalescent

with the basal fovea, the latter narrow and elongate; elytral punctures very

large, widely separated in the rows ; pubescence very sparse; color blackish-

The species above defined as lacerta, has been identified from the

somewhat unsatisfactory figure given by Motschulsky.

U. nucleatus n. sp.—Of the same form as lacerta; pubescence pale

flavate, rather sparse but denser and conspicuous on the elevated ridges, and

in twelve spots on the posterior two-thirds of the elytra, disposed on each

elytron as follows: one just before the centre, three in an oblique line at

posterior third, and two in a line nearly parallel to the suture, rather indis-

tinct, and very near the apex. Head small, rather coarsely and sparsely

punctate. Prothorar as wide as long; posterior angles small, acute and promi-

nent; base four-fifths as wide as the disk; surface finely tuberculate, each

tubercle with a small lateral puncture bearing a stiff subrecumbent seta.

Scutellum extremely minute, twice as long as wide, pointed, slightly tumid.

Elytra with fine feeble coste, the intervals deeply punctate, the humeral costa

very strong toward base, the base also very strongly tumid at one-third the

width from the suture to the sides, the posterior densely pubescent spots also

slightly tumid. Length 3.0-4.2 mm.

California (Humboldt Co.).

Occurs in great abundance in the Hoopa Valley, and may be dis-

tinguished at once from lacerta, not only by the characters given

in the table, but by the form of the smooth and impunctate furrow

which extends along the lateral edges of the pronotum behind the

antennal excavations. In the present species this furrow extends

nearly in cireular are from the excavations, past the basal angles,

and terminates at the rounded median basal fovea, while in lacerta

it is narrower and deeper, and terminates at the basal angles; this

character is comparatively constant. In dacerta the densely pubes-

cent spots referred to as a prominent character of nucleatus, are also

visible and in nearly the same positions, but they are always feebler;

the length of lacerta is 4.0-5.0 mm.

CaHLOTAXI Horn.

The form of the body in this genus somewhat resembles that of

Coniontis, but is as a rule rather more broadly and evenly elliptical,

the prothorax being more strongly narrowed from base to apex.

The sculpture is stronger and denser, and the sete, which are seldom

prominent and nearly always recumbent in Coniontis, here become

much denser and more erect, in this latter respect resembling those

of the aberrant Coniontis obesa Lec. The species are entirely

confined to the small island of Guadalupe, off the coast of Lower

California.

Most of the material before me has been recently collected by

Mr. G. W. Dunn; the series is very extensive, amounting to about

forty specimens, and indicates three species which may be distin-

guished as follows :—

Form broadly elliptical ; sides arcuate.

rather coarse, deep, very dense, sparser on the occiput; a small median area

at the base impunctate. Prothorax transversely, strongly convex, fully twice

as wide as the median length ; sides feebly convergent from base to apex and

feebly, evenly arcuate ; apex broadly emarginate ; base nearly straight, except

at the sides where it becomes distinctly sinuate; basal angles distinctly pro-

duced posteriorly, right when viewed laterally, not rounded, apical very

Guadalupe Island.

The present species, which is represented by a series of eight

specimens, is immediately distinguishable from the others by its

narrow subeylindrical form, parallel and much more rectilineal

sides, and generally coarser pronotal punctuation.

C. muricata Horn.—Represented by a good series showing slight

variation, especially noticeable in the size and density of the pro-

notal punctuation. The color varies from dark brownish-ferrugi-

nous to piceous-black. One specimen differs in its more broadly

oval form.

Length 8.0-10.5 mm.; width 4.3-5.5 mm.

C. punctulata Horn.—This species is represented by a homogene-

ous series of twelve specimens. The color varies from rather pale

rufo-ferruginous to piceous-black.

Length 9.5-12.0 mm.; width 4 8-6.0 mm.

All the species of this genus have a narrow, more or less incom-

plete, median pronotal line which is impunctate.

The genus Ceelus is peculiar to the coast regions of California,

and is found in abundance in the sand dunes which line the sea-

shore. ‘The species are somewhat closely allied, but scarcely to so

great a degree as in Ceelotaxis and Coniontis. They may be recog-

nized by the characters given in the following table :—

punctate; sparsely punctate near the base, very convex, strongly declivous to

the clypeal suture, which is well marked ; clypeus feebly convex, very broadly

and strongly sinuate anteriorly; labrum large, rufous in color; near the

clypeal suture there are several coarse flavate sete. Prothorar slightly more

than twice as wide as long, transversely, strongly and evenly convex; sides

feebly convergent from base to apex, distinctly and evenly arcuate; base

transversely truncate; angles—viewed laterally—very slightly obtuse and

scarcely at all rounded ; apex strongly emarginate, fringed with flavate sete ;

angles evenly and rather narrowly rounded ; disk irregularly punctate ; pune-

tures rather sparse in the middle, coarser and slightly denser near the sides ;

base having a fine coriaceous or semimembranous margin. Scutellum minute.

Elytra slightly longer than wide, slightly more than twice as long as the pro-

thorax ; sides parallel and feebly arcuate for three-fifths the length from the

base, together thence evenly and somewhat parabolically rounded behind ;

disk very strongly convex, finely rugulose, rather coarsely and not densely

punctate; punctures evenly distributed, slightly coarser and sparser than

those of the pronotum, slightly asperate. JZegs rather short and robust ; tarsi

slender, first joint of the anterior produced beneath the next three and the

basal portions of the fifth. Length 8.8-12.5 mm.

California (Monterey ; San Pedro).

The distinguishing features of this species are its large size and

peculiarities of pronotal sculpture. In c7liatus the punctures of the

pronotum are fine and nearly evenly distributed over the entire

disk, while in grossus they are slightly coarser, and are almost

entirely wanting in a broad band, crossing the disk at about one-

third its length from the apex, but not attaining the lateral margins.

This character is quite constant throughout a series of ten specimens

which I have before me.

C. globosus Lec.—I obtained two specimens of this species at

San Diego, California. It may be distinguished from ciliatus and

grossus by the very coarse and much denser pronotal punctuation,

and the broadly oval form, being even more dilated than grossus.

From arenarius it differs in its much denser punctuation and slightly

broader form.

C. arenarius n. sp.—Form rather broadly and evenly elliptical, convex,

shining, piceous to piceo-castaneous. Head much broader than long ; clypeus

broadly and feebly sinuate at apex; lateral angles broadly rounded; suture

deep, straight; surface rather coarsely, densely punctate. Prothorax widest

slightly before the base, more than twice as wide as long; sides strongly con-

vergent from base to apex, rather strongly arcuate; basal angles slightly

rounded; apex broadly emarginate; disk convex, coarsely, sparsely and

where also they are intermingled with finer punctures. /ytra as wide as the

prothorax, broadly rounded behind, but very slightly longer than wide, slightly

more than twice as long as the prothorax ; surface convex, coarsely, deeply,

rather sparsely and asperately punctate ; punctures slightly denser and more

California (San Pedro, Los Angeles Co. 2).

This species somewhat resembles the smaller forms of grossus,

but may be known by the broadly rounded clypeal angles, these

being narrowly rounded and distinctly produced anteriorly in that

species.

_C. ciliatus Esech.—This species is very abundant about San

Francisco. The series of thirty specimens before me indicates but

slight variability except in size, the specimens ranging from 4.8 to

8.0 mm. in length.

LARVA.

The following description will serve for the identification of the

larva of Celus ciliatus. The specimens upon which the descrip-

tion is based were found in

a small sandy tract, in which

the imago was more than

usually plentiful, and un-

doubtedly represent the true

truncate at base and apex; third small, oblique, sides nearly parallel, twice

as long as wide, two-thirds as long as the second, apex truncate. Mentum

granulose, also coarsely asperate; gular peduncle trapezoidal, well marked.

Ligula slender, projecting far beyond the mentum. Labial palpi small, ap-

“parently of two joints, terminal slender, oblique, much longer than wide.

Eyes wanting.

Prothorax wuch longer than wide, slightly narrowed from apex to base; sides

very feebly arcuate; apex and base broadly, transversely truncate; surface

cylindrical, having a double row of four small setigerous punctures near the

middle and extending from base to apex; lateral suture inferior ; under surface

behind the coxe conical, ascending upward from the base, shining, glabrous

anteriorly, setose toward base. Legs far before the middle, short, robust, com-

pressed ; coxee approximate, short; basal joint triangular, with a few short

robust tubercles near the apex interiorly ; second larger, triangular, with a

double row of small tuberculiform spines along the inner apex; third as long

as the second, longer than wide, with a row of long, erect, very strong spines

along the inner edge; terminal claw very large, acuminate at apex.

. COELOMORPHA ». gen. (Coniontini).

Body oval, convex, sparsely and minutely setose above, ciliate at the sides.

Head inserted in the prothorax to the middle of the eyes, short, broad ; clypeus

rounded at the sides, broadly sinuate anteriorly ; mentum moderate, obtrape-

zoidal ; maxille broadly exposed at the sides ; maxillary palpi well developed,

third joint small, obconical, one-half as long as the second, fourth as long as

the preceding two together, elongate, moderately dilated, cylindro-ovoidal,

obliquely truncate within at apex; labial palpi small, third joint feebly

dilated, cylindro-ovoidal, acuminate at apex ; antenne very short, incrassate,

10-jointed, first joint short, inserted in front of the coarsely granulated eyes

and under the overhanging sides of the clypeus. Legs rather slender, spinu-

lose; posterior tarsi slender, basal joint elongate; anterior tarsi scarcely as

long as the tibie, first joint large, produced beneath the second and third

joints; tibiz not sensibly produced exteriorly at apex, terminating in two

short spurs and several small spinules. Epipleure broad, rapidly diminishing

in width toward the elytral apices which they attain. Scutellum minute,

triangular.

This genus is well distinguished from Celus by its 10-jointed

antenne and broad epipleurz, also by the form of the prothorax.

The labrum is strongly retractile, and in three of the four speci-

mens examined is completely invisible, the-mandibles being fully

exposed from above; the organ is indeed so fully retracted that

merely the apex can be seen, even by looking far under the clypeus,

which is separated from the mandibles by considerable intervening

space. The fourth specimen is paler in color, and has the labrum

protruded, showing this to be rather large and as usual broadly

Coleopterological Notices. 183

sinuate at tip. The labrum is freely retractile in a great many

other genera of Tenebrionide.

The genus Ceelus is a highly specialized form of the group Coni-

ontini, which embraces two distinct types, distinguished primarily

by antennal and tarsal structure, and represented by Cclus and

Coniontis. The genus Celotaxis is the connecting bond between

the two sections, since it possesses the long slender antenne of

Coniontis, and, in a rudimentary degree, the tarsal structure of

Celus. Eusattus is closely related to Coniontis. Calomorpha, on

the other hand, while exhibiting a decided relationship with Celus,

is a still more highly specialized and extreme form, and perhaps

may be considered a transition toward a group or genus now ex-

tinct or not as yet discovered. This view is principally based upon

the broad epipleure and the form of the basal portions of the pro-

thorax.

The prolongation of the basal joint of the anterior tarsus, which

is most highly developed in Celus and Celomorpha, is very mode-

rate in Ceelotaxis and nearly obsolete in Coniontis, although in the

latter a distinct tendency to prolongation may be perceived, the

joint being very obliquely truncate at apex. In Eusattus the basal

joint is much longer and more slender, and nearly every vestige

of the prolongation is lost. If, therefore, the group be arranged

systematically in accordance with this character, the genera would

stand in the following sequence: Ca@lomorpha, Celus, Ceelotaxis,

Coniontis, and Eusattus.

As a general rule in this group the basal angles of the prothorax

are prominent and produced posteriorly, and, although in Ccelus

and a few species of Coniontis this character is nearly obsolete and

the base of the prothorax almost straight and transverse, we can

even in these cases clearly perceive the tendency to posterior pro-

longation. In Colomorpha, however, this character is completely

reversed, for the base of the prothorax becomes evenly and poste-

riorly arcuate throughout its width, the basal angles being broadly

rounded and gradually coarctate with the sides.

C. maritima n. sp.—Rather broadly oval, convex, shining, piceous to

pale ferruginous; under surface and legs slightly paler. Head scabrous,

herissate with coarse erect sete ; antenne very short, gradually and strongly

incrassate, slightly compressed, scarcely two-thirds as long as the head; eyes

very coarsely granulate. Prothorax distinctly more than twice as wide as long,

broadly convex, margined along the base, which is broadly and evenly arcuate,

irregularly scattered punctures in the middle, which are coarse and excessively

feebly impressed ; near the sides the punctures are much more dense, stronger

and distinctly scabrous or subasperate. lytra connate, very convex; sides

parallel and distinctly arcuate for three-fourths the length from the base;

together broadly rounded behind when viewed vertically, acute with the sides

straight when viewed longitudinally ; disk excessively minutely subgranu-

The species above described is the smallest member of the group.

Several specimens were secured by ‘Mr. G. W. Dunn, who informs

me that its habits are entirely similar to those of Ceelus.

ULOPORUS n. gen. (Tenebrionide).

Head short, broad, subdeflexed. Clypeus broadly rounded, not obliquely

elevated at the sides. Eyes convex, moderate, coarsely faceted, extending

slightly further beneath than above, neither divided nor emarginate. Antenne

inserted under the acute lateral edges of the clypeus, almost adjoining the

eye, moderate in length, very slender, the last three joints abruptly larger

forming a distinct oblong club; first and second joints elongate-oval, slightly

more robust, the first slightly the longer and wider; third very slender, three

times as long as wide, rather distinctly longer than the fourth; eighth

obconical, fully as long as wide; ninth abruptly much wider, subtriangular,

wider than long; tenth obtrapezoidal, twice as wide as long; eleventh as wide

as the tenth, oval, slightly wider than long. Labrum very short, strongly

transverse, truncate, the membranous band separating it from the clypeus

fully as long as its exposed portion. Maxille large, greatly exposed and

prominent; palpi well developed ; second joint long and slightly clavate;

third short ; fourth very large, strongly securiform. Ligula short, indistinct ;

palpi rather small, not very robust ; third joint rather longer than the second,

feebly conical, twice as long as wide. Mentum small, slightly elongate, dis-

tinctly narrowed from apex to base and supported on a moderate peduncle.

Prothorax short, wider from apex to base, the sides coarctate with those of

the elytra, the sides of the pronotum margined with an elevated bead, the

apex and base not margined, the latter fitted closely to the elytra. Prosternum

short in front of the cox, rather widely separating the latter, the process

very largely developed behind the cox, the apex angulate and received in a

deep impression of the mesosternum ; development behind the coxze—near

their inner margins—as great as before them in the same longitudinal line.

Coleopterological Notices. 185

Mesosternum very short ; coxz widely separated, having a distinct trochantin.

Metasternum moderate, the episterna moderate in width; posterior coxze almost

contiguous, just visibly separated. Legs short; femora moderately robust ;

tibie short, having two sets of terminal spurs, one at the inner and one at the

outer edge; spurs short and rather slender ; tarsi moderate in length, densely

pilose beneath ; first joint elongate, penultimate very small, the basal joint

of the posterior about as long as the entire remainder, the second obliquely

and distinctly lobed beneath. Scutellum rather small, strongly transverse,

strongly rounded behind. Epipleure moderate in width, entire, horizontal

behind, slightly broader and feebly inflexed toward base. Body evenly ellip-

tival, moderately and evenly convex.

The posterior margins of the second and third ventral segments

being finely coriaceous, determines the position of this rather puz-

zling genus to be in the Tenebrionine, and the eyes being more

prominent than the sides of the front, together with other charac-

ters above given, seems to indicate that it should be associated

with the Diaperini, where for the present it may be placed near

Platydema.

U. ovalis n. sp.—Evenly elliptical, moderately convex, somewhat strongly

shining, rather densely pubescent, the pubescence very fine and extremely

short; piceous, legs and antenne dark brownish-rufous. Head retractile,

very feebly, evenly convex, not in the least tuberculate, very finely and densely

punctate. Prothorax nearly twice as wide as long; apex about two-thirds as

wide as the base, the latter transverse with a broad very feebly arcuate median

lobe ; basal angles—viewed laterally—nearly right, not rounded, apical rather

broadly rounded, not at all prominent; disk finely, very deeply and densely

punctate. Lilytra rather more than twice as long as the prothorax; sides

arcuate; apex broadly rounded; surface very finely, densely punctate, with

vaguely defined series of slightly larger, widely distant punctures, the series

without the slightest trace of impressed strie. Length 1.7 mm.

Texas (Columbus).

This species is widely diffused throughout the States bordering

the Gulf of Mexico. I owe the specimen serving as the type of

the above diagnosis, to the kindness of Mr. E. A. Schwarz, who

discovered it in considerable abundance in the locality indicated.

APPENDIX.

CONTRIBUTIONS TO THE AMERICAN TERMITOPHILOUS FAUNA.

The species recently described in these Annals under the name

Termitogaster insolens, was the beginning of a series of discoveries

by Mr. J. Beaumont, in connection with certain studies in the life

habits of Termes and its allied genera.

The specimens of the species named above, were found incident-

ally by Mr. Beaumont in the galleries of termites, and were trans-

mitted by him, together with the neuropterous specimens serving

in part as the basis of a recent paper by Mr. P. H. Dudley, which

has just been published in the Transactions of this Academy. When

the attention of Mr. Beaumont was called to the importance of his

discovery, a more careful and systematic search was instituted,

resulting in the capture of several very small specimens which have

been placed in my hands for study by Mr. Dudley. These, as will

be seen below, are found to represent two entirely new and very

interesting genera, and, in addition, a new species of Termito-

gaster.

The coleoptera associated with the termites appear to be more

specialized and more intimately connected with the life habits of

their hosts than is the case with the more numerous myrmecophi-

lous species, and their taxonomy is more difficult to a corresponding

degree.

If any generalization can be made upon the little already known

of these curious genera, it would appear that, having become so pro-

foundly modified from the more usual types,—as seen for instance

in Spirachtha, which is one of the most remarkable instances of

adaptive development at present known,—it may be legitimate to

suppose that the neuropterous termites are an older type geologi-

cally than the hymenopterous ants, whose coleopterous guests are

generally less radically modified. This is of course under the

supposition that the rapidity of evolution or adaptation has been

approximately constant in the two cases, and that the coleoptera

are either intermediate in age between the termites and the ants, or

that they are the most ancient of the three. The truth is, probably,

Coleopterological Notices. 187

that the more highly specialized forms such as Spirachtha, Corotoca

and Termitogaster, are very nearly contemporaneous in origin with

the termites, while the less specialized forms such as Philotermes

and the genera here described, are intermediate in age between the

termites and true ants, since the latter genera are scarcely more

modified than the majority of myrmecophilous forms.

TERMITOGASTER Casey.

In elytral structure the following species is an anomaly, and has

scarcely a parallel in the entire order.

T. fissipennis n. sp.—Anterior parts slender, compactly joined, parallel

and subcylindrical; abdomen strongly inflated; color pale brownish-flavate

throughout, the exposed membranous portions white, the elytra slightly pice-

ous ; integuments slightly alutaceous, very sparsely setose.

Head scarcely as long as wide, not deflexed ; sides short and parallel; basal

angles narrowly rounded; base subtruncate, broadly arcuate, fitted into the

apex of the prothorax almost throughout its width, the neck very wide; upper

surface covered rather sparsely with minute subasperate points, very feebly

convex, broadly, feebly impressed in the middle. yes rather large, almost

evenly oval, very slightly longer than wide, convex and distinctly prominent,

finely faceted, longer and slightly more prominent than the tempora. Antenne

about two-fifths as long as the body, rather slender, cylindrical, loosely articu-

lated, strongly geniculate; basal joint subequal to the next three combined ;

two to four decreasing rapidly in length, the latter just visibly longer than

wide, obtrapezoidal, the sides but very feebly oblique; four to ten almost

exactly similar, the ninth as long as wide, the tenth just visibly transverse ;

eleventh cylindro-ovoidal, pointed, as long as the two preceding ; all the joints

sparsely setose and also finely pubescent, more densely so toward apex and

almost glabrous toward base; basal joint inserted in a small rounded entirely

dorsal fovea, adjacent to the antero-superior margin of the eye. Front before

the antennze advanced and strongly arcuate at apex, the surface just before

the apical margin elevated in two broad approximate cariniform tubercles,

immediately in advance of which the surface is very short and strongly decliv-

ous, the apical margin with a very minute deep rounded emargination, having

the sides in the form of fine carine and with the apical projections extremely

fine and acute, but not greatly advanced. Labrum distinct, transverse, broadly,

strongly sinuate at apex, with the surface strongly impressed opposite the

sinuation, separated from the front by a membranous sheath. Mentum large,

longer than wide, broadly impressed: apex very slightly narrower than the

base; sides parallel. Ligula very short, membranous, sinuate at apex—viewed

dorsally—with a short cylindrical porrect process projecting from the bottom

of the sinuation, the paraglosse apparently entirely obsolete. Labial palpi

very small, slender, the three joints decreasing uniformly and rapidly in width,

cylindrical, the last two subequal in length and together but slightly longer

than the first. Mavrille large, greatly exposed and prominent, especially

toward hase, the basal plate not in the least spinose ; outer lobe! well devel-

oped, lunate, corneous, with the apex acute, the inner edge fringed with

moderate sete ; inner lobe not made out. Mazillary palpi very large, conspicu-

ous, sparsely setose and irregular; basal joint small, rather longer than wide,

distinct ; second extremely asymmetric, slightly transverse. feebly convex on

the outer side, deeply excavated on the inner; third longer than wide, longer

than the second, ovoidal, gradually pointed, convex on the outer side, broadly

excavated on the inner, the fourth joint minute and spiniform, not oblique.

Prothorax slightly wider than the head and a little wider than long; sides

nearly straight and parallel; apex broadly strongly arcuate and rounded into

the sides, the apical angles obsolete ; base truncate throughout the width and

very feebly arcuate, the basal angles nearly right and very narrowly rounded.

Pronotum extremely feebly, evenly convex, not impressed, shining, excessively

minutely, sparsely, subasperately punctate, each point bearing an excessively

minute erect pale setiform hair; disk with two very widely distant subbasal

sete, and four, forming a trapezoid, in the apical half; viewed laterally the

flanks are narrow and perpendicular, scabrous, the lower edge sinuate just

behind the deflexed apical angles, which are acute and continued in front of

the coxe by the extremely short and almost lamellate ante-coxal prosternal

piece. Prosternum extremely short, not one-third as long as the pronotum.

Anterior core very long, loosely attached in the large membranous cavities,

finely scabrous, almost glabrous; femora long, the upper edge strongly arcu-

ate, the tibie as long as the femora, coarsely, rather densely setose within,

with two external rows of long slender widely-spaced setiform spines. The

disk of the pronotum in the male is very slightly wider, and more distinctly

longer, than the head; in the female the head is quite noticeably smaller,

with the tempora not quite so prominent.

Mesothorax moderate in length. Scutellum rather large, transverse, ogival,

in large part covered by the pronotum. Parapleure of the mesosternum finely

scabrous, large and well developed. Coxe very large, long, obiique, contigu-

ous; trochanters moderate, with a short ovtuse dentiform process within, the

femora rapidly narrowed near the point of attachment on the trochanters, the

tibize similar to the anterior but less densely setose within. j

Metasternum well developed. lytra equal in length and basal width to the

corresponding dimensions of the pronotum; sides straight and parallel, each

elytron distinct, the two separated by an interval, which at the apex is equal

1 In insolens the outer lobe is shorter, wide, arcuate, the apex truncate inter-

nally and bearing a row of short stiff spinules; the inner lobe is very short,

adjacent to the outer, the base obliquely corneous, the remainder semimem-

branous, the apex with a row of short spinules almost continuous with those

of the outer lobe. The disposition of the lobes is somewhat similar therefore

to that of Homalota and Euryusa.

to their own width, the sides of the interval straight and feebly convergent

anteriorly, abruptly terminating at a point just behind the scutellum, where it

is about one-half as wide as at the apex; surface coarsely and strongly reticu-

late, scabrous on the vertical flanks, sparsely clothed with exceedingly short

erect sete, and each with two long set near the inner margin, one near the

base and another behind the middle; flanks perfectly devoid of true epipleure.

Episterna large, triangular, very wide behind, but covered by the elytra before

attaining the humeri. Coxe with the inner portions large, porrect, contigu-

ous, longer than wide, truncate at apex, with the surface broadly convex;

trochanters large, simple; femora irregular, the upper edge broadly angulate

just beyond the middle, the edge thence broadly incurvate in circular segment

to the point of attachment; tibize sparsely setose within, the spinose sete of

the two external rows stronger. Hind wings wanting.

spurs. Tarsi 5-jointed, rather long, slightly compressed; first joint as long

as the entire remainder—slightly shorter in the anterior ;—fourth anchylosed

to the fifth.

Length 2.8 mm.

The above description is rather comprehensive, and includes

generic as well as specific characters in order that the numerous

differential characters distinguishing it from insolens may be made

more evident. The differences reside mainly in the structure of the

elytra, front, convexity and prominences of the eyes, and irregu-

larities of the trochanters and femora; in insolens the elytra are

absolutely connate, and soldered so completely together that the

suture is only indicated by a very feebly impressed line,—as great

a divergence from the corresponding structure in fissipennis as

could well be imagined. In both, the maxillary palpi are exceed-

ingly irregular, but in the present species they differ greatly from

those of insolens. The fact that the tarsi, antenne and general

habitus are similar or parallel to those of insolens, seems to indicate

that they should not be generically separated, but the great and

radical differences show at the same time that the genus is probably

one of great age in a geological sense.

In the male, the sixth abdominal segment is evenly emarginate

throughout its width in broad circular are, while in the female the

same segment is angularly produced in the middle for a short dis-

tance. The remarkable modification of the palpi and legs is not a

sexual peculiarity, being developed to precisely the same extent in

the male and female. The same remark applies also to 7. insolens;

in this species the sixth segment is truncate in the male, and feebly,

roundly lobed in the middle in the female. In insolens the two

mandibles are similar; they are rather slender, feebly arcuate,

having internally just behind the middle a large oblique squarely

truncate tooth; the portion beyond this is very slender and has, just

before the apex, a small oblique tooth.

ABROTELES 0». gen. (Aleocharini).

sody rather robust, subparallel ; abdomen slightly inflated.

Head nearly twice as wide as long, porrect, feebly convex ; sides very short,

parallel, feebly arcuate; base inserted slightly within the prothorax, not in

the least constricted ; basal angles not exposed ; apex broadly arcuate between

the eyes, the latter rather large, finely faceted, not at all prominent, rounded,

slightly angulate above. Antenne inserted in small fovee on the vertical sides

of the front adjacent to the middle of the anterior margin of the eyes, and just

above the base of the mandibles, 11-jointed, very robust ; first joint obconical,

longer than wide; joints two to eleven forming an elongate cylindrical club,

strongly tapering near the base and more feebly so near the apex, joined by a

narrrow point of support to the truncate apex of the basal joint at a point

near its lower margin, the joints separated by transverse sutures, apparently

mobile but each inserted far within the next preceding, subequal in length,

about one-third wider than long, except the second which is obconical and but

slightly wider than long, the third which is shortest and about twice as wide

as long, and the eleventh which is pointed, slightly compressed and as long

as the two preceding. Hpistoma membranous, short, broadly trapezoidal, the

apex broadly sinuate, not separated from the front by a suture, the chitinous

portion of the front abruptly terminating at a broadly incurvate line between

the bases of the antenne. Labrum well developed, prominent, twice as wide

as long; sides and apical angles continuously rounded; apex with a small

very deep median sinuation. Mandibles very short and stout, arcuate, slender

toward the acute apex, apparently with a large obtuse internal tooth at the

middle. MJentum large, slightly longer than wide; base and sides continuously

rounded ; sides slightly convergent in apical third and nearly straight; apex

truncate; surface flat, corneous in basal two-thirds, transparently membra-

nous in apical third, the line of demarcation sinuate and without visible

suture; chitinous portion with two long erect sete near the centre, arranged

transversely and nearly trisecting the width. JLigula moderate, membra-

nous, with a short rounded simple median process, the paraglosse small,

rounded and advanced as far as the apex of the median lobe. Labial palpi

3-jointed ; basal joint slightly longer than wide, cylindrical; second much

shorter, very small, cylindrical; third longer, subulate. Mauzille moderate,

not exserted ; lobes small, the outer enveloping the inner, not hooked at apex,

ciliate. Maxillary palpi nearly of the usual type, rather slender; second and

third joints subequal; fourth subulate. Under surface of head without trace

of lateral carine.

visibly arcuate; sides feebly arcuate and just perceptibly convergent from

base to apex; basal angles nearly right and extremely narrowly rounded ;

flanks rather shallow, very strongly defiexed, the lower edge straight, the

apical angles—viewed laterally—more broadly rounded than the basal. Hypo-

mera very strongly inflexed, almost parallel to the pronotal flanks. Prosternum

extremely short before the coxe, the latter large.

Mesothorax short. Scutellum triangular, strongly tramsverse, the apex ex-

posed. Mesosternal parapleure small, the epimera but partially developed,

leaving a considerable extent of membrane exposed adjavent to the elytral

humeri. Coxe moderate and not greatly exserted, the cavities confluent.

Metathorax longer. Elytra transverse, truncate at apex, as wide as, and

with the suture subequal in length to, the pronotum, not connate; suture

not beaded; hind wings apparently not well developed ; apical edge slightly

inflexed and membranous; flanks without true epipleure, not beaded.

Metasternal episterna very wide behind, their inner line tangent to the elytral

humeri. Coxe rather narrow, extending to the very wide episterna, contiguous.

Abdomen slightly wider than the elytra, the sides feebly arcuate, consisting

of six segments. Upper surface flat, each segment with a single apical series

of long stiff sete ; border wide, but not inclined. Lower surface convex, the

sete shorter and not definitely arranged.

Legs short and robust. Femora oblong, deeply excavated along the lower

edge toward apex for the reception of the tibie, the latter nearly equal in

length to the femora, parallel, truncate or slightly rounded at apex, more

finely pubescent, entirely devoid of terminal spurs or spinules, but having

several very long stiff sete along the external edge. Jarsi short, rather

robust, pubescent, 4-jointed on all the legs, the first joint of the posterior as

long as the next two together and equal in length to the fifth. Ungues very

small, arcuate. Anterior tarsi with a better defined tuft of long hair beneath

each joint.

There is no described genus known to me with which the present

can be compared. The robust compact cylindrical antenne are

characteristic of a number of termitophilous and myrmecophilous

genera, but none of these appears to have the posterior tarsi four-

jointed, as they very clearly are in Abroteles.

ments polished, not perceptibly punctate. Head very finely, sparsely pubes-

Pronotum very slightly less than twice as wide as long, very feebly, transversely

convex, not distinctly impressed, with a series of wide-spaced erect sete along

the apical margin and thence along the sides to the middle, where they abruptly

terminate; disk extremely sparsely pubescent, the hairs subrecumbent, very

minute toward the middle, longer and stiffer toward the sides, and posteriorly

to basal fifth, where they abruptly terminate in a transverse line parallel to

the base; surface thence to the base glabrous, except a few minute hairs

along the fine paler semi-coriaceous posterior edge, extending anteriorly along

the sides to about the middle. Flytra polished, depressed; sides straight,

feebly divergent from base to apex, almost exactly similar in form to the

pronotum, and almost imperceptibly longer, at base slightly narrower, very

sparsely clothed with rather stiff subrecumbent hairs, evenly but not regularly

disposed. Abdomen distinctly longer than the anterior parts combined, and

distinctly wider than the elytra; sides arcuate ; upper surface almost glabrous,

except the wide depressed border which is very finely and indistinctly pubes-

cent; under surface almost completely glabrous in the middle, but very finely

pubescent laterally. Length 1.8 mm.

Colombia (Panama).

In the male, which appears to be much more abundant than the

female, the sixth segment is very broadly rounded behind, the

middle of the apical margin truncate or excessively feebly incur-

vate; in the female this segment is broadly and feebly produced in

the middle in a wide broadly rounded lobe. The elytra also appear

to be very slightly shorter in the female.

In dedicating this species to Mr. J. Beaumont, I wish to acknowl-

edge a strong appreciation of the patience and scientific zeal on his

part, which have led in so short a time to a decided advance in our

knowledge of the interesting and apparently greatly diversified ter-

mitophilous fauna of Tropical America.

PERINTHUS bp. gen. (Aleocharini).

Body nearly as in Myllena, densely and very minutely pubescent.

Head small, strongly deflexed, deeply inserted in a rounded apical emargi-

nation of the prothorax ; portion behind the antenne much wider than long,

not in the least constricted at base, the latter covered by the pronotum ; sur-

face evenly, moderately convex. yes large, finely faceted, minutely, rather

densely setose, not prominent, rounded, occupying nearly the entire sides of

the head and, in repose, partially overlapped by the pronotum. Antenne

inserted in small fovee adjacent to the anterior margin of the eye on the

abruptly inclined and concave apical portion of the front—epistoma—which is

corneous and separated from the front proper by a transverse finely cariniform

line, which is sinuate behind each fovea, and anteriorly arcuate and more

advanced in the middle, abruptly terminating at each side at the antero-

superior margin of the eye; they are 11-jointed, moderate in length, very

strongly flatteued ; when viewed on the compressed side the sides are parallel

as far as the fourth joint, thence narrowed to the base of the third; first joint

rather slender, longer than wide; second slightly narrower, much shorter,

subeylindrical, longer than wide; third obconical, slightly longer than wide,

compressed ; fourth about as long as wide, obtrapezoidal; remaining joints

subequal, truncate at base and apex, with the sides almost parallel, in close

contact throughout the width, rather more than one-half wider than long on

the compressed side, and very slender, fully one-half longer than wide on the

edge, the eleventh joint slightly shorter than the two preceding. Apical mar-

gin of the epistoma membranous, truncate, the /abrum large, prominent, wider

than long, with the apical angles broadly rounded, the apex with a small

feeble median sinuation. J/andibles small, arcuate, acute and simple at the

immediate apex. Mentum large, equilatero-triangular, with the sides straight ;

surface flat ; apex very narrowly truncate; basal half corneous, apical mem-

branous, the dividing line feebly sinuate, not at all impressed. Ligula mode-

rate, wider than the apex of the mentum, rather long, with a prominent deeply

bifid median process, the paraglosse not well developed. Labial palpi robust

at base, the joints rapidly decreasing in thickness; third subulate. Mazille

moderate, feebly exserted ; lobes small, ciliate. Mazillary palpi of the usual

type, rather slender ; second joint shorter than the third; fourth subulate.

Lower surface without trace of infra-ocular ridge, the eyes approaching within

a very short distance of the buccal cavity.

Prothorax strongly developed dorsally, very feebly so ventrally. Pronotum

large, strongly, transversely convex, moderately narrowed from base to apex ;

basal angles evenly, somewhat obtusely rounded and slightly produced poste-

riorly, the base being incurvate and subtruncate between them. Hypomera

very wide, extremely strongly inflexed, parallel to the strongly inclined flanks

of the pronotum. Prosternum very small, extremely short in front of the coxe,

the latter large, conical and convex.

Mesothorax short. Scutellum invisible, completely concealed by the greatly

overlapping free edge of the pronotum. Mesosternal side-pieces ample, entire ;

coxe large, contiguous.

Metathorax moderate. Elytra truncate, apparently connate, very short and

transverse, as wide as the prothorax, but slightly more than one-half as long,

transversely convex; flanks strongly inclined, the epipleure very strongly

inflexed and almost parallel to the flanks, deep; suture very fine but distinct.

Metasternum wide; episterna narrow, parallel; cox# moderate, contiguous,

lamellate and transverse laterally.

Abdomen at base slightly narrower than the elytra, conical; sides rapidly

convergent to the acute apex and nearly straight, consisting of six segments

which are moderate in length, each having a single transverse series of long

widely-spaced apical sete above and beneath. Upper surface moderately

convex, the border narrow, normal, moderately deep. Lower surface more

strongly convex.

194 Coleopterological Notices.

Legs short. Femora stout, the flanks produced beneath slightly at apex,

forming a channel for the partial reception of the tibia. Tibiew slender, short,

cylindrical, truncate, without terminal spurs or spinules and devoid of long

external sete. Tarsi short, slender, cylindrical, densely pubescent, about

two-thirds as long as the tibiz, 4-jointed on all the legs; first joint of the

posterior distinctly longer than the next two together and a little longer than

the fourth. Ungues small and slender.

This genus is also somewhat isolated, harmonizing but remotely

with any of the more usual forms of the great and composite group

to which it is assigned. The extraordinary compressed, almost

tape-like antenne, deep flanks of the pronotum and elytra, which

extend far below the plane of the lower surface, very short elytra,

long conspicuous tactile sete, and four-jointed tarsi, form a combi-

nation of characters for which it is difficult to find a fitting place in

the series.

The sexual characters, also, are very singular. In the male the

apex of the abdomen is not modified beneath, the sixth segment

being evenly rounded behind, but dorsally, the posterior edge of the

first segment is strongly emarginate in iniddle fourth, the bottom

of the emargination being transverse. In the female the sixth

segment is rounded as in the male, but the basal segment is entire.

P. Dudleyanus n. sp.—Piceous ; abdomen slightly paler; under sur-

face, legs and antennz pale brownish-flavate ; surface lustre alutaceous, the

pubescence exceedingly short, fine, dense, slightly cinereous and conspicuous,

the long tactile sete very conspicuous, these consisting of six longitudinal

series on the pronotum—counting those of the lateral edges—and a transverse

series just before the middle of the elytra, the latter being simply the terminal

setz of the pronotal series, the sete of the abdomen being a further continu-

ation of the pronotal series. Head small, only the occiput visible from above,

the anterior portions of the body appearing to be semicircularly rounded, much

less than one-half as wide as the base of the prothorax; antenne about as

long as the head and prothorax together. Prothorax nearly one-half wider

than long, narrowed from base to apex, subconical; sides very feebly arcuate.

Elytra about equal in width to the prothorax, strongly transverse; sides

parallel and nearly straight ; disk scarcely perceptibly more than one-half as

long as the pronotum. Abdomen distinctly longer than the anterior parts

combined, conical, acute. Leng h 1.4-1.7 mm.

Taken in considerable abundance by Mr. Beaumont. A good

series has been given me by my friend Mr. P. H. Dudley, to whom

it gives me great pleasure to dedicate this very interesting species.

Coleopterological Notices. 195

In glancing through the plates of Schiddte’s splendid work on

coleopterous larve, we cannot resist drawing a few minor generali-

zations with reference to the great persistency of larval type which

prevails throughout some families, as for instance the Scarabeide

and Tenebrionide, and the enormous diversity of type exhibited by

others, notably the Staphylinide, there being scarcely a correspond-

ing diversity of imaginal type in the latter, although the imago is

undoubtedly more heterogeneous than in either of the families before

mentioned. Incidentally we may perhaps be warranted in inferring

that the Scarabeide and Tenebrionide, being more homogeneous

and less differentiated in both larval and perfect stage, are more

recent in origin than the strongly differentiated Staphylinide ; this

is of course under the general premise that multiplication of species

is due to differentiation from fewer and more synthetic ancestral

forms, although I am aware that Dr. Sharp holds that there is but

slight evidence of such divergence in the Dytiscide. The truth is,

probably, that the Staphylinide constitute one of the most ancient

types of coleoptera.

Regarding the curious object described below, it can only be said

that if it be staphylinide, as there is some reason to suppose, it will

add another notable element to the heterogeneity characterizing that

interesting family. Or, conversely, its wide departure from the

usual types of coleopterous larve will not, of itself, be an obstacle

in the way of its assignment thereto. In this connection it is

desirable to make the following observations :—

1. The specimens were received in two small tubes which, in one

instance, contained besides only specimens of Termitogaster insolens,

and in another, only Perinthus Dudleyanus. Mr. Beaumont seems

to have been careful to isolate his material, and it may be very

safely assumed that the larve and beetles were taken together from

the same nest.

2. As far as its general nature is concerned, I believe it to be cole-

opterous, although in antennal structure it is exceedingly exceptional

for that order, being approached in this respect, within my knowl-

edge, only by Cyphon. The dense squamose vestiture, enormous

development of the labial palpi and tarsal structure are also exceed-

ingly peculiar.

3. Assuming it to be coleopterous, I am quite convinced that it

cannot be related in any way to Termitogaster, but think that it

may possibly be the larva of Perinthus, the long tactile sete of the

196 Coleopterological Notices.

upper surface, as well as the conical and attenuate form of the

abdomen, reminding us forcibly of P. Dudleyanus.

Whatever future investigation may prove it to be, the following

short description will serve to make known its most salient charac-

ters :—

Body fusiform, obtusely rounded in front, attenuate and acute behind—

nearly as in Lepisma, but with the abdomen more strongly and evenly coni-

cal,—convex, and covered densely above and beneath with large pearly-white

closely recumbent strigose scales; integuments soft, membranous and pure

white throughout. The head is defiexed, densely squamose, devoid of eyes

and ocelli, having the antennz inserted on the front, approximate and sepa-

rated by a narrow very feeble ridge, very perceptibly attenuate from base to

apex, rather more than one-fourth as long as the body, cylindrical, 12-jointed,

the subbasal joints short, closely approximate or subconnate, the outer more

elongate and more loosely articulated, the joints annulated with fine impressed

grooves, one to three in number. The maxillary palpi are moderate in length,

cylindrical, 4-jointed, the last joint longest. The labial palpi are large and

strongly developed, with the last joint very large, ovate, pointed at apex,

concave without and convex within. The three segments of the thorax are

distinct, the flanks thin and descending very noticeably below the plane of

the lower surface, the pronotum as long as the mesonotum and metanotum

combined, each of the dorsal segments, including those of the thorax, bearing

a transverse apical series of long widely spaced tactile sete. The six legs are

short, the coxe large, conical, the femora robust, the tibize robust, cylindrical,

each with a large terminal spur; tarsi cylindrical, composed of two joints, the

second twice as long as the first; claws two in number, minute, arcuate. The

abdominal segments are ten in number, counting the small terminal segment,

which bears a small axial anal style composed of seven or eight joints; there

are also two short lateral anal stylets, composed of a few closely connate joints ;

the sutures between the abdominal segments almost concealed by the dense

vestiture. The length of the largest specimen examined is 2.5 mm., the

greatest width being 0.8 mm.

One of the most remarkable structures distinguishing this larva

is a very large fleshy appendage projecting from the lower surface

of the abdomen, just behind the fifth segment, and nearly as large

as the entire abdominal vertex beyond it. It is mobile about its

point of attachment, elongate-oval, longitudinally and very narrowly

divided throughout the length, forming two thick elongate cylindro-

conical lobes, which are densely, finely pubescent, and provided in

addition with long sparse sete, especially at the sides. The lobes

are divided by transverse sutures into six segments, of which the

three basal are very large, together occupying four-fifths of the

length, the three last small and composing the rapidly acuminate

Coleopterological Notices. 197

portion; at the apex of each there is a very short two-jointed styli-

form process. This organ is held in repose in a long very deep ex

cavation extending through the last four or five abdominal segments,

so that when at rest it is not distinctly noticeable, its lower surface

being continuous with the lower surface of the abdomen. It is

apparently an auxiliary organ of locomotion, analogous to the infra-

apical process characterizing many well-known staphylinide larve ;

but no such development as this has to my knowledge been observed

before.

Another larva-like object, possibly of a coleopterous nature, was

inclosed in the tube containing the only specimens of <Abroteles

Beaumonti which were obtained, but I am very doubtful of its

connection in any way with that species; it seems to be too large

and wide and to contain more matter than would suffice for the

body of the insect mentioned.

The large well-developed eyes, large securiform maxillary palpi,

and elongate 5-jointed tarsi are wonderful characters, almost irre-

concilable with what we know of coleopterous larve. The follow-

ing description will perhaps serve for its future recognition :—

Body evenly oblong-elliptical, depressed, with the upper surface broadly,

feebly convex, broadly rounded before and behind. The upper surface is

strongly reticulate, alutaceous, pale brownish-piceous in color, and covered

sparsely with very short robust spinose sete. The head is deflexed very

strongly, reposing upon the under surface of the prothorax ; it is rather large,

triangular, the eyes at the sides convex, large, and composed of many coarse

convex facets. The antennz are inserted in very large widely distant fovee

on the front before the eyes, and are defective in the only specimen; there are

four joints remaining, the outer deeply annulated, and showing that there has

been at least a terminal process broken therefrom. The epistoma is large and

separated by a distinct broadly sinuous suture. The labrum large, subquad-

rate. Maxillary palpi well developed, with the last joint very large and

strongly securiform. The six legs are about equal, rather long and well

developed; cox very long, conical, obliquely recumbent posteriorly, the

posterior large flat; femora elongate, flattened ; tibia long, cylindrical, with

two strong well-developed distant terminal spurs; tarsi long, very slender,

cylindrical, the posterior nearly as long as the tibie, distinctly 5-jointed on

all the legs, the first and fifth joints elongate, the intermediate short; claws

two in number, well developed, arcuate. The pronotum is much wider than

long and longer than the other two parts of the thorax combined, it is finely

canaliculate in the middle throughout the length. The abdomen consists of

198 Coleopterological Notices.

nine very short segments, the sutures very deep and distinct, the apex with

two pairs of very short anal stylets, but without median style. Length 2.4

mm.; width 1.0 mm.

It is possible that this may be an apterous larva-like female

imago. The integuments are soft and membranous, the head and

upper surface semicoraceous. The mandibles are short stout, alike,

and deeply notched and bifid at apex.

The general form of the body somewhat approaches that of the

larva of Syntomium zxneum as figured by Schiddte, but is more

elongate and with the sides more parallel.

Read October 7, 1889.

The catalogue here presented for publication was begun by me

about five years ago, but has been constantly delayed by the numer-

ous additions, and species for verification, which have been reported

or submitted to me as having been taken within the limits specified.

In the preparation of this catalogue I have availed myself of the

experiences of various collectors in this vicinity ; and it is as com-

plete as it can be made in the present state of our knowledge of the

local species, although it will be seen that much is yet to be added,

especially in the Tortricide and Tineide.

Special effort has been made to give as far as possible the food-

plants of each species, for the benefit of those who are desirous of

rearing the Lepidoptera of the region. For information relating to

the species of which the early stages are known, the student is re-

ferred to the catalogue of the described transformations of N. Am.

Lepidoptera, by Henry Edwards (Bull. No. 35, U. 8. Nat. Mus.).

This being the first list of the Lepidoptera of the region ever

published, it may possibly contain some inaccuracies, and for such I

would ask the indulgence of the entomological fraternity. I would

be greatly obliged to those who will inform me of any error they

may detect and also of any addition to the species and food-plants

that they may be able to make.

I also desire to acknowledge my special indebtedness to the fol-

lowing gentlemen, who have generously assisted me in my work ;

IV.—A Review of the American Species of Thread-fins

(Polynemidz).

BY PHILIP H. KIRSCH.

Read October 14, 1889,

In this paper I have given the synonymy of the Thread-fins or

Polynemide known to inhabit American waters, and an analytic

key by which the species may be distinguished. All the specimens

examined by me belong to the Museum of the University of Indiana.

Most of them were collected by Dr. Jordan and his assistants.

Inpiana University, July 8, 1889.

CHARACTERS OF THE POLYNEMID.

Body obiong, compressed and covered with rather large, loosely

inserted, ctenoid scales. Lateral line continuous, continued on the

tail, usually forked with a branch on each lobe. Head entirely

scaly ; snout more or less conical, projecting over the mouth, which

is rather large, inferior, with lateral cleft; premaxillary protractile,

its spine vertical; maxillary without supplemental bone, extending

much beyond the eye, which is anterior, lateral, rather large, with

adipose eyelid. Villiform teeth on jaws, palatines, and sometimes

on vomer. Pseudobranchize concealed. Branchiostegals 7. Gill-

membranes separate and free from the isthmus. Gills 4, a slit be-

hind the fourth. Two separate dorsals, somewhat remote from each

other, the first of 8 feeble but rather high spines, the first and last

spines very short, the third longest ; the second dorsal equal to first

in height but base somewhat longer, of soft rays only. Anal fin

either similar or much longer than soft dorsal; caudal fin rather

long, widely forked. Second dorsal, anal, and caudal fins more or

less covered with small scales; the first three or four dorsal spines

winged. Ventrals I, 5, abdominal, but not far removed from pec-

torals; pectoral fins moderate, placed low, in two parts, the lower

Annats N.Y. Acap. Scr., V, April, 1890.—16

232 A Review of American Species of Thread-fins.

and anterior portion of several filiform articulated appendages, free

from each other, said to be organs of touch. In the young, the

dorsal, caudal, and pectoral fins are dusky, the anal and ventral fins

white; all the fins grow darker with age, the pectorals usually be-

coming black, the operculum blackish. Bones of the skull with a

well-developed muciferous system as in Sctenidex. “ Basis cranii

double, with tube; post-temporal bifurcate; scapula with median

foramen; superior pharyngeal bones 4. Brachial ossicles divided ;

two normal, supporting the dorsal fin, one longitudinal without

rays, and one a plate on the coracoid, supporting the pectoral fila-

ments.”’ (Cope.) Stomach ccecal, with a few pyloric appendages.

Air-bladder various, sometimes wanting. Vertebre 24. Genera 4,

Galeoides, Polistonemus, Polynemus, and Polydactylus, the last two

only are found in America; species about 25, of which 5 are found

in America. Inhabit tropical seas, and entering rivers. Most of

them are valued as food fishes.

This peculiar family constitutes the group or suborder Rheg-

nopteri, characterized chiefly by the peculiarities of structure and

attachment of the pectoral fin. Its relations appear to be with the

Sciznide on the one hand and with the Mugilidx on the other, but

these resemblances may be superficial.

ANALYSIS OF AMERICAN GENERA OF POLYNEMID.

a. Anal fin much longer than soft dorsal, of about 30 rays; vomer without

teeth ; preoperculum entire ; free filaments of pectorals longer than body.

236 A Review of American Species of Thread-fins.

Habitat. South Atlantic and Gulf coast of North America.

Etymology. xr, eight, via, thread.

Following the suggestion of Dr. Jordan, I have regarded Poly-

nemus octofilis Gill as the adult form of Polydactylus octonemus,

from which it differs only in having darker pectoral fins and shorter

pectoral filaments, differences which occur in other species of Poly-

dactylus with age and no doubt in this one also.

The specimens examined by me were taken by Dr. Gilbert at

Charleston, S. C., where it is very rare, entirely unknown to the

fishermen.

America, 66, 1885.

Polynemus melanopoma Giinther, Fish. Centr. Amer., 421, 1869 (San José).

Habitat. Pacific coast of Tropical America.

Etymology. Latin, opercularis, from its dusky blotch on the operculum, found

also in most other species.

This species is known to me from specimens dredged by the

‘“‘ Albatross” in the ocean south of Panama.

RECAPITULATION.

V.—A List of State and Local Floras of the United States

and British America.

BY N. L. BRITTON.

Read Feb. 24, 1890.

In the Bulletin of the Torrey: Botanical Club, vols. viii, et seq.,

there are published “Contributions towards a List of the State and

Local Floras of the United States,” by Mr. W. R. Gerard and

myself. The present paper is an attempt to bring this up to date

and supply the numerous omissions of the former work, with the

addition of lists published for the Canadian Territory. In this 1

have been greatly aided by botanists all over the country, and it is

believed that the present enumeration contains most of the local

floras. No attempt has been made to incorporate all the notes and

short lists of local observations, but it has been found difficult to

draw the line in many cases. As in the former contribution lists

of species without exact localities have been indicated by (A);

those giving stations by (B);>those giving stations with notes or

occasional descriptions by (C); and descriptive floras by (D).

I cannot hope to have covered all the literature of this subject,

and will be grateful for further notes and memoranda in the view

of preparing a supplementary list. The present is brought down

to May, 1890.

VI.— The Crinoidea of the Lower Niagara Limestone at

Lockport, N. Y., with New Species.

BY EUGENE N. 8 RINGUEBERG,

Read April 14, 1890.

That the lower portion of the Niagara Limestone represents a

period favorable to the existence of great multitudes of the echino-

dermata, the profusion of their fragmentary remains gives abundant

proof; especially during the time indicated by the band known as

the Lockport Encrinal Marble, which is almost entirely made up in

places of disconnected plates, columns, and other portions of their

calcareous skeletons.

But conditions conducive to their preservation entire were not

present; the deposit being too gradual, giving time for the decay of

the organic connective portions, with the subsequent separation of

the more indestructible parts; so that while many species, and quite

a number of genera are known to have flourished, by the remaining

evidence of their plates, but few present enough material to base

species upon.

Among the genera may be noted Caryocrinus, Gomphocystites,

Heterocystites, Glyptaster, Icthyocrinus, Calceocrinus, Periecho-

erinus, Lyriocrinus, Dimerocrinus, Lecanocrinus, Catillocrinus,

Eucalyptocrinus, Macrostylocrinus, and some others, the last four

of which are known to be represented by two or more species, but

few of these, after years of careful search, have yielded enough con-

nected evidence to prove identity or to warrant description.

In many instances in which the calyx or the entire individual

remains intact, the fossil has so nearly the same consistence as the

matrix, and the union between the two is so intimate, that it is

almost an impossibility to separate or clean them satisfactorily, and

only in a small portion of the layers are the components favorable

to successful weathering.

While not enough is presented in most cases for specific determi-

nation, enough can be made out to show that the larger proportion

are specifically distinct from those found in the underlying shales.

Among the species determined are Caryocrinus ornatus, Say;

Hucalyptocrinus tnconspectus, Ringueberg; Heterocystites arma-

tus, Hall; Lecanocrinus macropetalus, Hall; Periechocrinus spe-

ciosus, Hall; Dimerocrinus immaturus, Hall; Calceocrinus con-

tractus, Ringueberg; and the five new species described below.

Callicrinus acanthinus nu. sp. PI. III, fig. 1.—Calyx sub-angulate,

low, ornamented with spines, nodes, and radiating ridges. Ten of the spines

are long and slender and spring in a circle from the middle of the calyx, being

directed outwards and upwards, their apices reaching to a point about as high

as the top of the calyx. Base nearly as broad as the rest of the calyx ; deeply

excavated by a wide pentagonal depression, which slopes upwards and in-

wards from the narrow rim of the excavation to about one-third of the height

of the sides, its angles are directed radially and present at abort the middle

of the first radials. Basal plates small, and of the usual form. First radials

bent abruptly outwards and upwards near the middle; their outer upper sides

being curved inwards so as to conform to the pentagonal base and meet the

margins of the adjoining first radials without the formation of an angle at the

sutures ; they have six ridges, usually strong, radiating from their center, a

median one directed inwards towards the columnar facet, lying in the angle of

the basal excavation ; two laterally and slightly inwards meeting the corre-

sponding ones from the opposite plates and forming the rim of the base, they

also represent the point of the upward curvature of the plates; the next two

are directed outwards and upwards towards the sides upon which rest the

large inter-radial plates, these are the least prominent of any at the point of

radiation, but become rapidly more prominent and strong at the margin of the

plate; the remaining ridge is projected outwards on a plane with the base,

as far as, and on a line with, the sides of the calyx where it is abruptly trun-

cated by a rectangular turn upwards, thus forming a subacute node or spine.

The second radial is broader than high and has a strong median ridge extend-

ing from one lateral margin to the other. Third radial gradually elevated

from the lower and outer sides forming the sloping base of one of the long

spines which it bears, and at times has slight ridges meeting those from the

adjoining large inter-radials which are similarly elevated and spiniferous.

The apices of the plates, and consequently the bases of the spines being on

the same plane, in the third radials and the large inter-radials. The spines

of the third radials are flattened antero-posteriorly and those of the inter-

radials laterally. The rest of the plates forming the calyx all have their

ventral portion elevated into nodes or ridges and are of moderate size. Inter-

maxillary plates, arms, column, etc., unknown.

This remarkable crinoid has been known to me for quite a num-

ber of years past from disconnected plates, but it was not till some-

what over a year ago that a specimen was found which preserved a

little over half of the calyx. I was at first inclined to publish it as

a Eucalyptocrinus, but upon mentioning it to Chas. Wachsmuth,

Esq., of Burlington, Iowa, to whom a diagram of the species was

sent, he called my attention to its being a Callicrinus. I quote

from a letter of his to myself, dated March 21, 1888.

‘The specimen of which you send the diagram is in my opinion a Callicrinus

(Angelin) and not Eucalyptocrinus. The genus Callicrinus has not heretofore

been recognized from America, but I judge from some excellent specimens

which I examined lately from Wisconsin, that not only your new species but

also Hall’s Eucalyptocrinus cornutus should be referred to it, and probably

Roemer’s Hucalyptocrinus ramtfer.’’

From the Lower Limestone of the Niagara Group, Lockport,

Naw:

Norr.—All the plates and their relative proportions as figured in the restora-

tion can be observed in the type specimen, which shows the interior of the

calyx and a small portion of the exterior, with four nearly perfect spines.

I also wish to express my indebtedness to Chas. R. Keyes, Esq., who at the

request of Mr. Wachsmuth sent me a tracing of C. murchisonianus, from Jcono-

graphia Crinoideorum in stratis Succi siluricus fossilium, page 15, Tab. xxviii,

fig. 14, which will be found reproduced on the same plate (PI. III, fig. 2) with

C. acanthinus for comparison, and on account of its being of interest in exhibit-

ing parts of the calyx not shown by the specimen from the Niagara, as this is

the first publication to my knowledge of this genus here, although as before

stated the credit of the generic identification is due to Mr. Wachsmuth.

Dendrocrinus? nodibrachiatus n. sp. Pl. III, fig. 6.—Calyx

small, campanulate; sides incurved, evenly tapering to base, which is of the

same size as the upper end of the column; rim spreading. Ventral tube long

and in its (apparently) compressed condition, about one-half as wide as the

diameter of the top of the calyx. Arms ten, long, not tapering till near the

end, with nodose joints; pinnulate? Column round, composed of unequally

arranged joints, having wide and narrow median rims. Under basals five, as

wide as high, pentagonal. Basals hexagonal, with the exception of the poste-

rior, which supports the anal upon its truncate top. Third or radial ring com-

posed of seven plates—five radials, an azygous, and a large anal. Radials

broad, pentagonal, except the right posterior, which is quadrangular and

elevated above the plane of the rest by the underlying large azygous, which

is pentagonal and of nearly the same size as the rest of the radials, and rises

to the same level, lifting the radial above it to the same position as is occupied

by the first brachial plates in the other series. Anal plate large, subhexa-

gonal, extending up as high as the right posterior radial; but one other plate

belonging to the anal area can be made out in the type specimen—this is

slightly smaller than the first, and rests upon its upper face. Brachials 3 X 5;

of the same character as the arm joints; on each third brachial a bifurcation

takes place. Arm joints nodose, gradually decreasing in size near the distal

extremity, without further bifurcation some 28 joints can be counted in one

of the arms. Column round, joints unequal in width by reason of the differ-

encé in extent of the central elevations or rims ; between the wider ones there

are from one to three narrower. It increases somewhat in size after leaving

the calyx as far as observed, z.e., about 2 cm.

Another specimen, preserving some of the arms and the ventral

tube, shows what seem to have been pinnules; but their exact

nature cannot be made out on account of the imperfection of the

specimen. The ventral tube is long and rather wide in its com-

pressed state, and is exposed up to about one-half of the height of

the arms above which point it is covered by them. Five rows of

plates can be seen on the posterior side; the median of which are

smooth, hexagonal, and depressed below the level of the others;

the two adjoining rows interlock with the median, and are of the

same height and about the same width, but are pentagonal and

alternate with the adjoining outer rows, having a straight suture

line between these rows. The plates of each of the adjoining rows

are of the same pentagonal character with their truncate sides pre-

senting at the straight longitudinal suture line, and have the suture

lines between the successive plates depressed, and at their termina-

tion opposite the middle of the opposite plate, there commences a

groove which extends half-way across the plate. This arrangement

gives a zigzag ornamentation on each side of the tube.

From the Lower Niagara Limestone, Lockport, N. Y.

I have been somewhat at a loss as to the exact generic relations

of this crinoid, on account of what seem to be pinnules, but these

may turn out to be lateral armlets.

Glyptaster (Eucrinus) lockportensis n. sp. Pl. Ill, fig. 4.—

Calyx pentagonal below; angles marked by moderately elevated radial

ridges, which arise from the underlying basals and meet in the first radials.

This ridge grows stronger and more sharply defined after its bifurcation with

the second and third series of radials. Surface ornamented by sharply defined

and prominent large granules and ridges, arranged in a radiating manner

on the larger plates. Under basals small, projecting but little beyond the

column. Basals large, pentagonal, posterior one heptagonal. Primary radials

3 X 5, secondary 2 X 10, and of the tertiary series three can be made out in

the only portion so far observed, 7. e., the posterior side. In the posterior side

the anal area contains upwards of twenty plates, of which the first anal rests

upon the truncate top of the posterior basal; it is the largest plate in the

area; immediately above this are three somewhat smaller plates, and the suc-

ceeding rows of plates decrease regularly in size towards the top.

The Crinoidea of the Lower Niagara Limestone. 305

This species is readily distinguished by its coarse granules or

nodes which coalesce and form ridges or striz towards the margins

of the larger plates to meet corresponding ones from the plates

adjoining; and the strong radial ridges being comparatively smooth

above the primary series. In the primary radials the granulations

and rugee extend somewhat upon them.

From the Lower Niagara Limestone, Lockport, N. Y.

Quite a number of bases and parts of the sides have been found,

but no entire calyx as yet. Subgen. Hucrinus differs from Glyp-

taster only in the possession of a tertiary series of radials. Wachs-

muth and Springer give no American species in their list, and no

other publication of one has fallen under my observation.

Icthyocrinus conoideus n.sp. Pl. III, fig. 5.—Calyx inverted coni-

cal, evenly tapering by straight sides to the broad base; almost circular in

section, there being just the faintest suggestion of angularity radially. Arms,

column, ete., unknown. Sub-basals three, entirely hidden by column. Basals

five, with just the outer angles presenting beyond the base. The lower angle

of the radial opposite the smaller sub-basal extending upon the base.

Three series of primary radials can be observed in the type

specimen ; they are of the usual form, with a smooth or minutely

granulose surface ; two of the series contain three successive radials,

while the other has four; above each primary series the first primary

radials are preserved. In another specimen there are four secondary

series of three each.

This species is readily distinguished from I. levis, of the shales,

by its elongate calyx with straight sides and its proportionately

broader base. ‘

From the Lower Niagara Limestone, Lockport, N. Y.

Eucalyptocrinus muralisn.sp._ Pl. III, fig. 3.—Calyx inverted

conical; sides nearly straight, but slightly curved outwards; base well

defined, about twice as wide as the excavation for the reception of the column.

Surface covered with coarse, closely arranged, and at times coalescing, gran-

ules with spreading bases, and which are but slightly raised above the general

surface of the plates, and seem to be without any definite arrangement into

radiating lines, as is usually the case in this genus. Column and arms un-

known. Basal plates hidden from view by the retention of a joint of the

column. First radial plates large and evenly rounded in at the base to the

excavated portion, where they are abruptly bent upwards forming its perpen-

dicular walls. The rest of the plates are of average size and construction, and

have the outer face convex, evenly rounded up from the sharply defined suture

lines.

306 The Crinoidea of the Lower Niagara Limestone.

The peculiar surface marking, the convex plates with the con-

comitant well-defined suture lines, taken in connection with the

shape of the calyx, will serve to distinguish this from the associated

species in this group.

From the Lower Niagara Limestone, Lockport, N. Y.

The types of the species are all in my collection.

BY THOMAS L. CASEY.

Read October 6, 1890,

The greater part of the present paper is devoted to the Tenebri-

onidz, in an attempt to elucidate the more obscure portions of the

family as represented in the United States. The foundation for

this somewhat laborious work rests upon a large amount of mate-

rial, brought together by the writer during several years’ residence

in California, supplemented and greatly increased in value by the

collections of the National Museum, which were placed in my

hands for study and identification through the liberality of Prof.

C. V. Riley.

It gives me pleasure also to acknowledge my indebtedness to many

other friends for specimens which have still further augmented the

material, and consequently enhanced the utility of the systematic

revisions. Prominent among these are Messrs. H. F. Wickham,

KE. A. Schwarz, and Wilhelm Jiilich.

New Yorx, August 11, 1890.

Note.

As generic and specific words are mere symbols for the designation of a

species, it seems desirable that they should be withdrawn as far as possible

from exceptions to general rules of grammar, and, that in this respect at least,

they should be treated in the abstract as mere aggregations of letters. The

rules of gender should be made uniform, so that generic symbols ending in a

certain manner shall demand a certain definite and invariable gender in the

specific symbol.

Let us take, for instance, the word Adonis. To apply this word to a genus

of beetles with any idea of its absolute meaning, would of course be absurd,

and, if this be granted, there can be no tenable reason for regarding its gender

as masculine and consequently exceptional to the general rule for words

Annas N. Y. Acap. Scr., V, Nov. 1890.—21

308 Coleopterological Notices.

ending in is. In fact, in the present state of the science, it is impossible to

convey any usefully discriminating meaning by a generic word, for it is evident

that such combinations as Platysoma, Megacephalus, Brachycerus and hundreds

of others, could each be applied with equal force of meaning to a great number

of widely diverse genera.

The only course left, therefore, is to consider the generic name as a simple

harmonious combination of letters, having a Latin form, constructed without

absolutely essential reference to rigidly correct orthography in the language

from which it may have been derived, whether Greek, Latin, or aboriginal

American, and subject to constant rules of gender which shall be independent

of linguistic caprice. The word may or may not have a meaning in the original

language from which it is taken, although in any event, the meaning is of

but little material importance. In regard to gender some such rule as the

following might be suggested :—

MAscuLine.—All words ending in as, es, os, us, 7 or 0.

FemintnrE.—All words ending in a, is or s preceded by a consonant, includ-

ing y, and, in addition, words ending in e or x.

NevutrEer.—All words ending in m or n. 4

An attempt at uniformity involving a suppression of the rules of orthogra-

phy, and made in a spirit similar to that which has prompted the above

remarks, has recently come into quite general use—I allude to the growing

custom of writing all specific names, whether proper or common, with a small

initial letter. All such rules as this, which have for their object the attain-

ment of simplicity and uniformity in scientific nomenclature, are undoubtedly

very desirable.

In conclusion I cannot forbear alluding to the unspeakable confusion, into

which the gratuitous meddling of mere linguistic purists, has thrown a great

deal of what should be rigid and unchangeable symbolization. If we can by

any means avoid the unnecessary alteration of original spelling of generic

words in the future, it is all that can be hoped for.

COLYDIID A.

The Colydiide comprise an extremely heterogeneous assemblage

of species, in treating which we must either greatly amplify and

generalize our conception of the value of generic characters as

derived from experience in the order at large, or must create a

relatively great number of genera each very limited in extent.

There can be but little question of the propriety of the latter course,

if we wish to make the value of generic characters—somewhat

indefinite at best—as nearly uniform as possible throughout the

order, although it necessitates at the same time a greater complexity

of nomenclature. A similar condition is of constant recurrence

throughout the order. In the Carabide it occurs among the

Coleopterological Notices. 309

Lebiini, in the Pselaphide among the Ctenistini, and in the Sta-

phylinide among the Omalini; it is even more pronounced in many

parts of the Cerambycide, Tenebrionide, and Otiorhynchide.

In regard to the genus Murmidius and its allies, it is quite clear

that their affinities are wholly with Cerylon and Philothermus, and

not at all with the Histeride, although a few modifications of struc-

ture which are characteristic of that family reappear in them.

These resemblances are limited to the prosternal lobe and elevated

lines alone, for the antenne are received in deep prosternal excava-

tions in true Colydiides, as, for example, in Megataphrus, and the

retractibility of the legs is of very variable extent and consequently

of subordinate value as will appear below. The prosternal lobe,

even, is fully developed only in one of the four genera. On the

other hand the antenne, in general form and position, the trophi,

and the structure of the abdomen, are entirely similar to those of

the Cerylonini.

MEGATAPHRUS 1. gen. (Megataphrini).

Head porrect ; sides far overreaching the base of the antenne, the eyes very

rudimentary, consisting of four or five very large circular facets arcuately

bordering the anterior basal margin of a small tubercle situated at the sides

of the extreme base. Antenne inserted far in advance of the eye, very slen-

der, 11-jointed, the club abrupt, consisting of two separate but rather approxi-

mate joints, one to eight very slender, nearly nude and very sparsely setose,

cylindrical, one to five longer than wide, three longer than two and nearly as

long as four and five together, six to eight gradually shorter but equal in

width, nine slightly transverse, ten abruptly much wider, transverse, eleventh

much wider than long, longer than and fully as wide as the tenth, apical

joints more densely pubescent. Antennal grooves at the sides of the head

very wide and deep, continued directly on to the hypomera, where they are

extremely large and deeply excavated, the excavation nearly straight, parallel

to the lateral edges, continuing through anterior three-fifths of the prothoracic

length and extremely disproportionate to the size of the antenne, being fully

ten times as voluminous and of very great depth. Mentum transverse, with a

very strong angulate carina extending from the basal angles to the middle of

the apex; interior of the angulate portion concave, not carinate. Ligula short,

with a rounded discal tubercle. Palpi moderate; last joint of the maxillary

rather large, slightly longer than wide, much longer and wider than the third,

ovoidal, obliquely and broadly truncate at apex. Mandibles obtusely notched

at apex. Labrum short and transverse, the basal half feebly declivous; the

apical vertical. Cox moderately widely separated throughout, the anterior

as widely so as the intermediate, small, globular, very deeply inserted, the

process wide, truncate, scarcely extending beyond the coxe, the cavities open

310 Coleopterological Notices.

behind, the posterior oval, rapidly attenuate laterally and scarcely attaining

the metasternal episterna which are rather wide. Abdomen composed of five

segments which are free or very nearly so, separated by very coarse, deeply

impressed and straight sutures; basal segment nearly as long as the next

three together. Legs short, moderately robust; tibie slender, the spurs not

distinet ; tarsi slender, tetramerous ; joints of the posterior all elongate, the

fourth much shorter than the first three combined.

On comparing these characters with the corresponding ones of

Rhagodera and Anchomma, it is readily seen that the antenne

differ radically, for, besides being of a usual type and not in the

least perfoliate, they have the last joint wide, while in the genera

mentioned the last joint is small, exactly as in the Asidini of the

Tenebrionide ; in this connection attention is called to the small

terminal joint in Narthecius. Megataphrus further differs from the

Khagoderini in having antennal fosse at the sides of the head and

prosternum not only present, but developed to an extraordinary

degree, and in the elongate basal segment of the abdomen; it how-

ever resembles the tribe mentioned in having the antenne inserted

at a great distance from the eyes, which in the present instance are

all but obsolete, and in the structure of the anterior coxx, acetabula

and prosternal process, also in its roughly scabrous appearance.

There seems to be no course left, therefore, but to consider it the

representative of a distinct synthetic tribe.’

M. temuicornis n. sp.—Oblong, rather robust, parallel, strongly, un-

evenly convex, piceous-black, dull and roughly scabrous. Head moderate,

wider than long, very coarsely punctato-tuberculose, the sides tumid over the

antennie, the occiput with a small median fovea. Prothorax anteriorly some-

what as in Coxelus, about one-fourth wider than long; base and apex equal,

the latter truncate between the large and greatly advanced apical angles,

which are rather acute and not rounded; base pedunculate, the peduncle

short, three-fifths as wide as the disk, transversely truncate; sides parallel,

evenly and distinctly arcuate, minutely but strongly serrate, the teeth tri-

1 The European genus Tarphius, which appears to approach Megataphrus

in some respects, differs in its broader form of body with non-pedunculated

pronotum, in its well-developed eyes which are more approximate to the point

of antennal insertion, and in the very short basal joint of the tarsi; in Mega-

taphrus the hind tarsi are slender, the basal joint being subequal in length

to the next two together. In Tarphius, which is considered a member of the

Synchitini, the antennal grooves are, according to Wollaston, not really exca-

vations, but more feeble impressions. It cannot be denied, however, that the

tribe Megataphrini is also closely allied to the Syuchitini, of which it might

perhaps with almost equal plausibility form a group.

Coleopterological Notices. 311

angular and erect, strongly emarginate posteriorly just before the basal angles

of the peduncle; disk strongly elevated in middle third, with a large fovea at

each side in the middle, very coarsely tuberculose and dull. Scutellum ex-

ceedingly minute, angulate and attenuate at apex. lytra scarcely as wide as

the prothorax and about three-fourths longer; sides nearly straight; apex

evenly rounded; base truncate between the humeri which are rounded but

anteriorly prominent, each elytron with three moderately elevated discal cost

the two outer, as well as the lateral edge—viewed laterally—broadly sinuous

in the middle; intervals each with a double series of extremely coarse approxi-

mate punctures, the sutural interval with a single series. Under surface dull

and roughly scabrous. Length 2.4 mm.

California (Humboldt Co.).

A single representative only was taken by the author near the

bay, probably under loose and greatly decayed bark. The integu-

ments throughout, in¢luding the femora and tibie, are clothed with

very short and sparse, robust, but not squamiform sete, the tarsi

very finely, sparsely pubescent beneath and nearly glabrous above.

LYCOPTIS n. gen. (Lycoptini).

The very aberrant genus which I have been forced to regard as

the representative of a distinct tribe of the Colydiidw, may be essen-

tially defined in few words as follows :—

Sides of the head anteriorly not at all extended and but feebly developed

horizontally, the basal joint of the antenne almost entirely exposed from

above, although inserted under the sides. Antenne slender, rather short,

7-jointed, joints three to six slender, seventh forming an abrupt, elongate-

oval, solid club, which is apparently composed of three fused joints with a

feeble terminal process possibly representing a tenth joint; antennal grooves

not well developed. Eyes rather large and prominent, coarsely faceted. Palpi

with the last joint elongate-oval, gradually and obtusely pointed at apex and

much longer but not thicker than the penultimate. Mandibles finely notched

at apex. Coxe all narrowly separated, the anterior small, transversely oval,

gradually pointed externally, the cavities narrowly open behind; posterior

strongly transverse, attaining the margin of the epipleure. Metasternum

large, with a short coarse ante-coxal transverse groove; episterna not very

narrow, gradually diminishing in width posteriorly throughout the length,

attaining the coxe, the epimera obsolete. Legs rather slender but short, free ;

tarsi tetramerous, the basal joint extremely small, the fourth about twice as

long as the first three together ; tibial spurs extremely short.

The prosternal process is rather narrow and extends behind the

coxe, the apex abruptly expanded and received in a small moder-

ately deeply impressed excavation of the mesosternum ; its surface

312 Coleopterological Notices.

is transversely tumid, and the lateral angles acute. The meta-

sternal process is short, angulate and transversely tumid or sub-

carinate. The epipleurz are horizontal and nearly equal in width

throughout, except near the base, where they become a little wider

and almost vertical.

The tribe Lycoptini is related in some of its characters to the

Synchitini, but differs in the structure of the anterior coxe which

are transversely oval and pointed externally, a character which is

extremely rare if not unique in the family. The 7-jointed antennz

also constitute a peculiar character, and there are only the feeblest

indications of division in the club visible under special conditions

of illumination, the amalgamation being complete; the third joint

is slender and much longer than the fourth. Lycoptis appears to

be one of those connective forms which, with increasing discovery,

will in all probability ultimately unite many of the small families

of Clavicorns.

L. villosa n. sp.—Oblong, parallel, rather depressed, rufo-ferruginous

throughout, feebly shining, the elytra more strongly so; entire upper surface

herissate with very long, erect, somewhat sparse but conspicuous hairs. Head

wider than long, the eyes prominent and convex, the sides before them short

and strongly convergent anteriorly from their inner margin; apex broadly

truncate; epistoma short, the suture transverse and distinct; sides of the

front at each side of the epistoma very slightly tumid ; labrum very short and

transverse ; upper surface feebly, evenly convex, coarsely and densely punc-

tate. Prothorax four-fifths wider than long, two-thirds wider than the head,

united to the hind body by a short peduncle Jess than one-half as wide as the

base; apex slightly narrower than the base, truncate between the slightly

advanced and narrowly rounded apical angles; base transversely truncate

throughout the width, the basal angles distinctly and rather broadly rounded ;

sides extremely feebly, evenly arcuate; disk very feebly convex but strongly

declivous laterally, the margins narrowly reflexo-explanate, the lateral edges

minutely crenulate, coarsely, very densely punctate throughout, without trace

of impressions. Scutellum transversely oval. lytra rather more than three

times as long as the prothorax and exactly equal to it in width ; sides parallel

and straight; apex evenly, semi-circularly rounded ; base truncate; humeri

right, not rounded; disk nearly flat above, strongly declivous laterally from

the sublateral carina; on each elytron there is at lateral third a strongly

elevated carina, the surface thence te the suture marked with five feebly

elevated lines, interrupted by distant punctares, the intervals each with a

LASCONOTUS Erich.

This is without doubt one of the largest genera of Colydiide,

and is particularly well represented in the Californian coast regions;

it is withal a clearly limited and but slightly composite genus,

although its species differ considerably in habit. The species be-

longing to the linearis group, for instance, are not found under

bark, but inhabit the leafy branches of trees, particularly pines,

and it will be observed that the general form of these species is

more cylindrically convex than those of subcortical habits.

Although the structural characters of the under surface are com-

paratively constant, there is very great variety in the sculpture of

the upper surface, which sometimes becomes very complex.

L. pertenuis n. sp.—Very slender, parallel, rather convex, dull and

scabrous, pale brownish-ferruginous throughout; pubescence short, robust,

rather sparse but more conspicuous in single narrow lines along the crests of

the elytral coste. Head rather large, a little wider than long, slightly con-

stricted at base, Hat above, coarsely, densely and indistinctly punctate, the

epistoma surrounded posteriorly by a deeply impressed, arcuate groove; eyes

rather large, moderately convex, the tempora about one-half as long; antennz

short and robust, the club oval, strong, the ninth joint much shorter and

narrower than the tenth. Prothorax a little longer than wide; base equal in

width to the head; apex a little wider, broadly arcuate; sides just visibly

and broadly sinuate ; basal angles not at all rounded in the male, rounded in

the female; disk very coarsely, rather densely but indistinctly punctate, the

interspaces very dull; pubescence forming an intricate and feebly marked

tracery ; surface broadly, feebly impressed along the middle, the impression

becoming narrower and vanishing toward base, where, on each side of it, there

is a narrow elongate feeble impression. Hlytra about two and one-half times

as long as the prothorax and just visibly wider, very distinctly wider than the

base of the latter; humeri narrowly rounded ; apex evenly rounded in circular

arc; disk cylindrically convex, each with four fine, feebly elevated, entire

ridges, the intervals each with two approximate series of coarse, very close-set,

non-setigerous punctures, the sete borne by very minute punctures at the

sides of the interval separating the series, one for every coarse puncture, the

sete subrecumbent and directed obliquely toward the ridges. Abdomen rather

coarsely but sparsely and indistinctly punctate. Length 2.4~-2.6 mm.

California (Monterey ).

The most slender species known to me, belonging near linearis

Cr., but smaller, pale throughout and with finer, sparser punctua-

tion, especially of the abdomen. As in the species mentioned the

real punctures of the pronotum are very fine, each situated on the

summit of a relatively coarse tubercle.

Structurally, this species differs from linearis in the antenne and

maxillary palpi, the antennal club being parallel and with joints

nine and ten almost equal in linearis. In pertenuis the terminal

joint of the maxillary palpi is shorter, more parallel and more

broadly truncate at apex; these differences are quite conspicuous

in degree.

L. nucleatus n. sp.—Rather slender, parallel, convex, piceous-brown,

dull; pubescence coarse, short and recumbent but not squamiform. Head a

little narrower than the base of the prothorax, parallel, broadly truncate,

very slightly wider than long, feebly constricted at base; upper surface rather

flat, coarsely, densely punctate and scabrous; eyes small, a little shorter than

the tempora, slightly prominent; antenne rather long and slender, very

sparsely clothed with long herissate sete which are very conspicuous on the

club, the latter elongate, subparallel and loose, joints one to six or seven

longer than wide. Prothorax fully as wide as long, strongly narrowed from

apex to base, the sides broadly but rather strongly sinuate throughout ; apex

much wider than the base, broadly, feebly arcuate; basal angles rather acute,

not rounded; disk with complex tracery and very feeble impressions nearly

as in pertenuis, coarsely granulato-punctate. Elytra nearly three times as long

as the prothorax and a very little wider than the disk of the latter; sides

parallel and almost straight ; humeri narrowly rounded ; apex very slightly

conjointly produced in the middle as a squarely truncate lobe; disk without

trace of longitudinal cost, but in their place having slightly broader flattened

nude and impunctate intervals, which are interrupted at long distances by

small tumid elevations, bearing a dense tuft of whitish sete ; spaces between

the flat tumuliferous intervals occupied by a double line of coarse, non-seti-

gerous punctures, the two series very approximate, the interval separating

them bearing a very closely-spaced double line of coarse yellowish sete, which

are pointed longitudinally backward. Abdomen very dull and scabrous, the

punctures rather sparse and indistinct. Length 2.7-3.4 mm.

California (Monterey).

I obtained a small series of this species from the blossoming

branches of the Monterey pine. Although belonging to the line-

aris division of the genus, it is at once distinguishable from any

other described form, by the densely pubescent nuclei of the elytra

and the absence of costal lines. It is more robust than linearis.

Coleopterological Notices. 315

L. apicalis n. sp.—Parallel, moderately slender, rather depressed, flat

above, the elytra vertical at the sides, dark rufo-ferruginous throughout, very

slightly shining ; pubescence very short and sparse, moderately coarse. Head

moderate, nearly as long as wide, quite distinctly narrower before than behind

the eyes, the latter moderate, very slightly convex and about two-thirds longer

than the tempora; occiput slightly constricted at base; upper surface feebly

impressed at the sides of the epistoma, finely, sparsely punctate, the punctures

becoming denser and coarsely tuberculous toward the sides; antenne well

developed, rather stout, the pubescence rather dense, moderate in length, club

wide, nearly parallel, rather loose, the ninth joint distinctly shorter although

but little narrower than the tenth, third scarcely one-half longer than wide.

Prothorax scarcely visibly longer than wide; sides extremely feebly convergent

from apex to base, straight in direction although slightly undulated; base

with a very short wide truncate median lobe; basal angles slightly obtuse but

not rounded ; apex nearly transverse but feebly bilobed, the margin of the

lobes tumid; disk finely, rather sparsely punctate, each puncture at the

summit of a small elevated tubercle; the tubercles dense; surface broadly,

feebly impressed in the middle in anterior two-thirds, also with three feeble

impressions near the base forming a posteriorly pointed triangle, otherwise

even. Elytra about two and one-half times as long as the prothorax and

nearly two-fifths wider ; apex semi-circularly rounded ; humeri very narrowly

rounded ; sides parallel and nearly straight ; disk with broadly elevated suture

and four rather strong straight coste on each elytron, the summit of the coste

distinctly, densely punctate, not very conspicuously setose, the intervals each

with two very approximate series of coarse close-set punctures, the small sub-

recumbent sete arranged as in pertenuis; scutellar series long and distinct ;

first discal costa abruptly obsolete at apical fifth, the surface between the

thence feebly elevated suture and the second costa nearly flat, polished and

extremely sparsely, finely punctate thence to the apex. Under surface

throughout very coarsely, densely, deeply and distinctly punctate, the punc-

tures slightly transverse and feebly reniform, the small inconspicuous sete

arising from their anterior margins. Legs moderate; tarsi slender. Length”

California (Santa Cruz Co.).

In some characters this remarkably distinct species is interme-

diate between the ordinary forms with all the elytral coste entire,

and the pusillus group in which the first discal costa is abbreviated ;

this abbreviation is most extreme in concavus.

L. concavus n.sp.—Rather robust, depressed, subparallel, black ; legs

and antenne rufo-testaceous ; upper surface alutaceous, the pubescence not

very coarse, extremely short, very dense throughout. Head slightly wider

than long, the sides arcuate and convergent before the eyes which are well

developed but not at all prominent, the tempora very short; base rather

strongly, abruptly constricted ; surface nearly flat, with two very large feeble

impressions separated by a longitudinal and feeble elevation; punctures sim-

ple throughout, fine but deep and rather dense; antenne rather short, the

club broad and almost parallel, third joint short, scarcely as long as wide,

very slightly longer and wider than the fourth. Prothorax very slightly wider

than long; sides rounded anteriorly, thence feebly convergent and nearly

straight to the broadly rounded basal angles; basal pedunculiform lobe ex-

tremely short and broad, truncate; apex transverse; disk abruptly and very

deeply excavated throughout the length, the excavation but slightly longer

than wide, and three-fifths as wide as the entire prothorax ; punctures rather

fine but deep and very dense throughout, simple and not in the least tubercu-

lous. Elytra about two and one-half times as long as the prothorax and very

densely punctate, the concavity having extremely indistinct unimpressed

series of very slightly larger punctures, the intervals between the lateral

ridges biseriately and rather finely punctate. Abdomen and metasternum

polished, rather coarsely, moderately densely and very distinctly punctate.

Legs moderate, the femora very robust. Length 2.8 mm.

New Mexico (Las Vegas). Mr. H. Meeske.

This small species belongs to the pusillus group and represents

an extreme development of its structural peculiarities; it is very

much broader than laqueatus Lec.

The three species of the pustllus group may be distinguished as

follows :—

First elytral costa feeble but traceable behind the middle.

Elytra gradually, rather strongly concave toward apex; base strongly

emarginate; pronotal punctuation simple throughout, without trace of

marginal bead extremely fine; punctures very coarse, perforate, sparse but

rather dense toward the sides, except near the base. Scutellum moderate,

transversely oval. lytra nearly twice as long as the prothorax and, in the

middle, nearly one-fourth wider than the latter; sides parallel and very dis-

tinctly arcuate; apex evenly rounded; disk with extremely feebly-impressed

with a single series of very minute widely distant punctures. Under surface

A conspicuously distinct species, distinguished from wnicolor by

its much larger size, piceous color, coarse punctuation, erect hairs

LAPETHUS n. gen. (Murmidiini).

Body oval, compact ; head deflexed, the trophi in part concealed in repose

by the short prosternal lobe. Antenne inserted in deep foveze on the front,

just before and between the eyes the condyle of the basal joint exposed when

the organ is reflexed, rather slender, straight, cylindrical, 10-jointed, the last

three joints fused into a robust, compact, oval and very abrupt club. Maxillary

palpi with the first two joints rather slender, the third abruptly very large,

oval, compressed, the fourth slender, subulate, obliquely inserted in the apex

of the third. Labial palpi with the first joint very small, second very large,

oval, compressed, the third subulate and oblique. Mentum small, angulate

at apex, finely and strongly carinate along the middle. Labrum as long as

wide, the sides straight and strongly convergent from base to apex, the latter

narrow and with a deep angulate notch; between its upper surface and the

epistoma there is a short transversely truncate basal piece which is corneous ;

both this and the labrum proper are retractile. Eyes rather small, coarsely

faceted. Pronotum widely separating the small globular coxe, the cavities

apparently open behind, the process wide, extending far behind the cox, the

apex broadly rounded and closely fitted in a corresponding emargination of

the mesosternum, its surface continuous with that of the mesosternum ;

hypomera wide, excavated throughout the width in anterior half for the

reception of the antennal club, the anterior portion of the excavation separated

from the median lobe by a deep elongate cleft for the reception of the funicle ;

318 Coleopterological Notices.

lateral angles of the median lobe rather acute and prominent, the apex truy-

cate. Middle and hind coxe very widely distant, the latter small, transverse

and attaining the metasternal episterna, the latter extremely narrow and

linear but dilated behind, the suture fine but distinct. Anterior and middle

legs retractile, the posterior free; tibize compressed, slender toward base,

swollen and obliquely truncate externally toward apex, the truncate surface

smooth and polished and bordered on each side by a fringe of short sete, the

external edge carinate from base to the truncation just mentioned; tarsi

slender, the first three joints small, subequal and, in the posterior, together

about one-half as long as the fourth ; claws slender, normal.

The last vestige of the posterior crural excavation is visible as a

fine straight line, extending obliquely from the inner side of the

coxa and vanishing near apical third of the first segment.

In the structure of the palpi, maxillary lobes, insertion of the

antenne and carination of the mentum this genus is an analogue

of Cerylon, but in the retractile legs and antennal excavations it is

allied to Murmidius; in fact it constitutes an almost conclusive

proof that the Murmidiini are merely a group of the Colydiide and

closely related to the Cerylonini, the principal distinctive features

being the 10-jointed antenne received in excavations. In Cerylon

the antenne are 11-jointed, the club being composed of two amal-

gamated joints as in Murmidius. In Lapethus the club is composed

of three fused joints.

The three genera Cerylon, Lapethus and Murmidius differ how-

ever in sternal structure to an astonishing degree, for in Cerylon

the prosternal process extends over the surface of the mesosternum

and in Lapethus is received in an emargination of the latter, while

in Murmidius the mesosternum extends over the surface of the

prosternum, advancing considerably upon it and partially conceal-

ing the anterior coxe.

L. discretus n.sp.—Rather broadly oval, moderately convex, dark rufo-

testaceous throughout, highly polished, the upper surface with rather long,

fine, erect and stiff sete which are very sparsely distributed. Head feebly

convex, extremely finely and sparsely punctate but coarsely and more densely

so toward base; epistomal suture completely obliterated. Prothorar nearly

one-half wider than long, at base nearly three times as wide as the head, very

strongly narrowed from base to apex, the latter broadly, feebly emarginate,

nearly one-half as wide as the base, the latter transverse, broadly, arcuately

lobed in the middle, closely fitted to the base of the elytra throughout the

width ; sides rather strongly arcuate, nearly parallel in basal third; disk

very vaguely, transversely impressed almost throughout the width near the

base, very sparsely, moderately finely punctate, the sides margined with a

thick acute bead. Scutellum moderate, very distinct, almost circular. Flytra

subequal in width to the prothorax and twice as long, gradually rather

strongly rounded at apex, the sides anteriorly very feebly arcuate; base

equal in width to that of the prothorax; disk with rows of very coarse punc-

tures which become feeble near the sides and almost completely obliterated in

apical third or fourth. Under surface extremely sparsely and inconspicuously

punctate, polished. Legs short, the femora rather robust. Length 1.8-2.0 mm.

California (Humboldt Co.).

I obtained two specimens of this extremely interesting species

under old bark near Humboldt Bay.

BOTRODUS 1. gen. (Murmidiini).

Body oblong-oval, rather strongly convex. Head deflexed, the trophi parti-

ally concealed in repose by the moderately developed prosternum. Eyes rather

large, rounded, coarsely faceted. Antenne inserted at the sides of the front

in very small fovee adjacent to anterior margin of the eye, 10-jointed, the club

moderate in size, abrupt, oval, solid and consisting of two amalgamated joints ;

basal joint rather large, broadly angulate anteriorly ; second much smaller,

conical ; three to eight slender, very compactly joined, affixed obliquely to the

apex of the second joint; antennal grooves wanting, the club received in a

small deep excavation in the apical angles of the prothorax, visible anteriorly

but not from above. Palpi not very robust, the last joint slender, acuminate,

conical and slightly oblique, in the maxillary nearly equal in length to the

penultimate and a little more slender. Mentum extremely small. Mandibles

finely notched at apex. Labrum very short and transverse. Epistoma ex-

tremely large, fully one-half as long as the entire head and continuous with it

in convexity, the suture very fine and extending between the antennal fovee.

Anterior coxe very small, globular, very distant, the cavities apparently open

behind, the prosternum with two very fine widely distant lines, diverging from

the coxe, the process very wide, extending under the mesosternum. Meso-

sternum between the coxe very broad, advancing anteriorly beyond the coxe

as a broadly rounded, heavily beaded lobe, which extends partially over the

prosternum, the metasternal suture very feeble. Metasternum very large, the

episterna narrow, inflexed behind to meet the coxe; suture very feeble;

posterior coxe small, transversely oval, widely separated. Abdomen consist-

ing of five segments with straight, rather feeble sutures, the basal segment

not quite as long as the remainder together. Legs rather short, not received

in excavations, the femora robust, extending laterally beyond the sides of the

elytra; crural cavities perfectly obsolete but represented by feebly elevated

lines, extending obliquely on the metasternum and first ventral segment, from

the inner limits of the coxe.

This genus has several characters in common with Mychocerus,

such for instance as the position and extent of the antennal excava-

320 Coleopterological Notices.

tion, but as the legs are entirely free I do not think that it can

properly be considered identical, especially as the general habitus

is quite different.

The structure of the mesosternum anteriorly reminds us some-

what of Phalacrus, but is perfectly similar to the same part in

Murmidius ovalis; in both, the fine sutural line separating the

sterna is posteriorly angulate, unimpressed and is situated at the

middle of the coxal cavities as in Cerylon; it is very feebly marked

in the present genus. In Cerylon the mesosternum is very much

longer and the prosternal process extends over its surface for a short

distance, as before remarked.

The absence of crural excavations and the imperfectly retractile

legs in this genus, together with the corresponding structure as

described in Lapethus, seem to prove that the retractibility of the

legs is not a character of even tribal importance. In fact the

10-jointed antennez and presence of antennal excavations are the

only characters of value which separate the Murmidiini from the

Cerylonini, and these two intimately related tribes are separated

from the majority of Colydiide by the frontal insertion of the

antenne. In this connection it should be stated that in the Both-

riderini the palpi are of similar structure, except that the last joint

has become larger, but it is still finely attenuate and conical; this,

together with the exposed insertion of the antenne, indicates a close

relationship.

B. estriatus np. sp.—Oblong-oval, rather convex, strongly shining, pice-

ous ; pubescence consisting of excessively minute, sparse, fine and recumbent

hairs growing from the punctures. /7/ead much wider than long, feebly, evenly

convex, feebly and coarsely reticulate, very finely, sparsely punctate. Pro-

thorax a little more than twice as wide as the median length, slightly narrowed

from base to apex, the latter broadly, feebly sinuate, the bottom of the sinus

broadly arcuate; apical angles rather broadly rounded ; base broadly angu-

larly lobed in the middle, closely fitted to the base of the elytra throughout

the width; sides nearly straight, arcuate anteriorly; disk evenly, broadly

convex, feebly reticulate, very finely, sparsely punctate, the sides margined

with a thick convex bead which extends along the apex as a very fine bead ;

base not margined. Scutellum very small, elongate, finely acuminate. Llytra

fully three and one-half times as long as the prothorax; base a very little

wider than the base of the latter, the humeri just visibly exposed; sides

parallel and very feebly arcuate ; apex broadly, evenly rounded ; disk evenly,

transversely convex, minutely and very sparsely punctate, the punctures

evenly distributed but without the slightest trace of serial arrangement.

Under surface extremely minutely and sparsely punctate throughout, polished.

Length 1.3 mm.

The tibie and tarsi are slender, the tarsi tetramerous, the fourth

joint of the posterior a little longer than the first three together,

the basal joint about as long as the next two, slightly dilated and

with a brush of long hair beneath, the remaining joints slender and

almost glabrous throughout. The tibial spurs are not distinct.

I am indebted to Mr. Schwarz, whose generous gifts of specimens

have often been referred to, for a representative of this very interest-

ing species.

CUCUJID.

As organized at present this family is perhaps the most compo-

site of the Clavicorns, several of the subfamilies exhibiting such

strong transitional affinities toward other families that there is

really very little reason for considering the latter distinct. The

Passandrine, for example, exhibit a very close relationship with

the Colydiide, and two of the four genera composing it in our

fauna have the tarsi tetramerous; as further proof of this relation-

ship it should be stated that some genera of Colydiide, as for

instance Sosylus, have a rudimentary process corresponding to the

jugular plates of the Passandrine.

NARTHECIUS Lec.

This very isolated genus should be removed from the Cucujine

and placed in the Passandrine, with the characters of which it is

in stricter harmony. The jugular plates in Narthecius, although

feebly developed, are distinct. The tarsi are perfectly tetramerous

throughout,’ with the basal joint small and the fourth long. The

five joints; the drawing is however incorrect, the division between the third

and fourth joints being an optical illusion in the somewhat imperfect specimen

elytra have each five fine ridges, the intervals being finely, sparsely

and sublinearly punctate. The epipleure are extremely narrow and

do not occupy the entire inflexed sides except at the humeri where

they become rapidly dilated as in many Tenebrionides. The meta-

sternum is extremely long, the side-pieces rather wide anteriorly,

but rapidly narrowing thence to the apex, where they are generally

more or less covered by the elytra. The lateral margins of the

prothorax are marked by an extremely feeble fold which is generally

completely obsolete near the apex. In the presence of a fine longi-

tudinal line near the sides of the pronotum Narthecius exhibits a

line of consanguinity with the true Cucujine, and the synthetic

nature of the genus is proved in addition by several other structural

characters.

The sexual modifications of the Passandrinz are not very con-

spicuous and are generally extremely feeble, in marked contrast to

the Cucujinee where these differences become extreme. I have but

little doubt therefore, that the characters which are employed in the

following table will be found practically independent of sex. The

three species before me may be thus distinguished :—

Median apical process of epistoma broader, bifid at apex.

Head very long; occiput with a distinct broadly impressed median groove

toward base; antenne scarcely as long as the head; nuchal constric-

tion distant from the eye by nearly twice the length of the latter;

supra-orbital carine extending behind the eye a distance far exceeding

its length. Prothorax much shorter than the head: pronotum un-

evenly punctate, more coarsely near the middle, finely so elsewhere.

Median process of the epistoma narrower and more acuminate, absolutely simple

and obtusely subtruncate at apex. Head not longer than wide, the occiput

without median groove; eyes larger, more convex ; nuchal constriction

more feeble, situated at scarcely more than the length of the eye behind

the latter ; supra-orbital ridge arcuate, obsolete at less than the length of

the eye behind its posterior margin; antennz robust, about one-half longer

than the head, the basal joint short and wide, flattened. Prothorax much

breviceps nt. sp.

The basal joint of the antenna is very different in s¢mulator and

breviceps and, in the former, somewhat resembles that of grandi-

ceps.

PTINID A.

PTINODES Lec.

The following species is referred to Ptinodes with some doubt ;

it however belongs to the group Anobia, and the abdomen and

metasternum are unexcavated, the antenne simple with elongate

club and received in repose between the widely separated anterior

cox, the femora clavate and the tarsi dilated.

P. cristatus n. sp.—Very robust, compact, subcylindrical, densely

pubescent and clothed in addition with long, erect hairs and fasciculate tufts

of sete, of which four on the pronotum are very approximate and prominent ;

integuments piceous-black, the vestiture confusedly variegated with white,

brown and black, the sides of the pronotum, humeral regions and two sutural

spots white and more prominent; pubescence of the under surface short, fine,

extremely dense, cinereous in color. Head moderate, feebly convex; eyes

large, prominent, coarsely faceted ; antenuze somewhat robust, the three outer

joints together much longer than the entire remainder, basal joint robust.

Prothorax about three-fourths wider than long; sides rounded at anterior

third, thence rather strongly convergent and nearly straight to the base, the

latter broadly, evenly arcuate, about as wide as the apex, in close contact with

the elytra throughout ; apex very feebly emarginate ; apical angles right, not

rounded; disk strongly gibbous in the middle, impressed near each apical

angle, not canaliculate, having small, unevenly scattered tubercles, each

bearing a long hair, the short matted pubescence growing from the inter-

spaces. Scutellum as long as wide, parabolic. lytra scarcely one-half longer

than wide, fully one-third wider than the prothorax, broadly rounded behind ;

sides parallel and nearly straight ; base broadly emarginate for the prothorax ;

humeri broadly exposed, rounded ; disk with small widely scattered tubercles,

The individuals of all the species vary remarkably in size. The

type of the species described by me as parvulus was labeled

‘‘ Arizona,” but as I have subsequently received an ample series

from the vicinity of Monterey, California, there may possibly be

some error in the former locality. This species is very isolated in

many of its characters, and is more widely separated from opaculus,

with which it has been considered synonymous, than any other

known species except striatus; its length is 2.4-4.7 mm.

It is almost superfluous to add that cavicollis Lec. is in no way

allied to strdatus, the punctuation of the elytra being of a totally

different kind.

TENEBRIONID &.

This large and interesting family is probably comparatively

modern in geological development, and may possibly be contem-

poraneous with the Scarabeide. The investigations made known

in the following pages are intended to exhibit—in an imperfect

and fragmentary way—the correlative affinities of the old and new

world faunz, as far as it has been possible to procure representa-

tives of the foreign genera, and especially in that obscure portion

involving the first few tribes of the subfamily Tenebrioninz ; also.

to classify the species pertaining to the more neglected of the

North American genera, such as the Thinobates, Coniontis and the

Blapstini.

In comparing the Tenebrionide of the palarctic fauna with those

of North America, it seems that as far as structural variety and

singularity of form are concerned, the nearctic species are con-

siderably less highly evolutionized. Such specialized types as

Areoschizus and Usechus, for instance, are represented with us by

two small genera, while in Europe there are several, exhibiting

great variety, such as Adelostoma, Eutagenia, Stenosis, Oogaster,

Dichillus and the curious Leptodes. The very diversified and con-

spicuous Pimeliini, the isolated Pedinus and very aberrant Cossy-

326 Coleopterological Notices.

phus, are peculiar to Europe and without any immediate allies in

North America, while the interesting genera Arthrodeis, Erodius

and Adesmia are represented by a few species of Edrotes, of very

much smaller size and much less conspicuous variety.

The European Asida and Blaps are almost exactly equaled in

extent and variety by the American Asida and Eleodes, but while

there are very few other palearctic genera exhibiting much persist-

ence of type, a considerable part of the remainder of the nearctie

fauna is made up of large genera, composed of small, less striking

and more monotonous forms, such as Eurymetopon, Emmenastus,

Coniontis, and Blapstinus. Even Opatrum, which appears to

replace our Blapstinus to a great extent, is composed of very much

larger and more varied species. On the other hand, however, such

peculiar forms as Sepidium, Elenophorus and Cephalostenus may

fairly said to be offset by our much more numerous Zopherini and

Embaphion.

A greater diversity of climatic and other physical conditions

prevailing in Europe is, in all probability, the direct cause of the

condition referred to, and the Tenebrionide are not the only family

which exhibits this superior elaboration, if such an expression be

allowable, for the same is observable to some extent in the Carab-

ide; but, as a partial compensation, the American Staphylinide

exceed the European in abundance and in diversity of type, to a

corresponding degree.

This may possibly be a collateral proof that the Staphylinide are

older geologically than the Tenebrionide (see Ann. N. Y. Acad. V,

p- 195), especially if we assume that early and comprehensive types

are more readily modified by environment than the later and more

specialized, for during the epochs immediately succeeding the Carbo-

niferous, North America probably possessed conditions far more

varied than those which then prevailed in Europe; consequently

the primitive and synthetic types of any family which may happen

to have existed at that time, would be more diversified, and would

transmit to the present a still more numerous and varied set of

typical forms. As the conditions which now make Europe superior

to America in evolutionizing power, were not brought about until

the Tertiary, it follows that any family which had its origin near

this epoch would be at present the more differentiated in Europe.

Coleopterological Notices. 327

TRIOROPHUS Lec.

The males of Triorophus are distinguished from the females by

a small, abruptly limited, slightly elongate-oval spot in the middle

of the basal segment of the abdomen; which is extremely finely,

densely punctate and excessively finely, velvety-pubescent. In this

connection attention is called to the fact that in a great many species

of Blapstinus, the ordinary punctures become slightly more densely

aggregated in the same region and probably for a similar reason.

The sexual differences in the present genus are otherwise very

feeble, the male being but just visibly less robust than the female.

The following species, represented by a male and female, belongs to

the lavis group :—

T. lecontei n. sp.—Robust, very convex, elytra strongly inflated, intense

black throughout; integuments strongly shining. Head very slightly nar-

rower than the prothorax, finely, sparsely punctate throughout, nearly smooth,

the frontal umbo large, very strongly elevated and subangulate when viewed

laterally, the median lobe of the epistoma long, angulate at apex ; mandibles

extremely densely punctate ; eyes rather small, less prominent than the lateral

lobes in front of them, the supra-orvital ridge strong and straight, with one

or two very short inner folds near the base only ; antenne very long, the tenth

joint triangular, longer than wide, shorter than the eleventh which is elongate-

oval. Prothoraxr nearly one-third wider than long ; apex one-third wider than

the base, truncate, the apical angles small but acute, anteriorly prominent

and dentiform, bearing a cluster of long slender sete which extend partly

over the eye; base transversely truncate, the basal angles slightly obtuse but

not rounded and a little prominent; sides moderately arcuate, more convergent

in basal half; disk very convex, coarsely, very deeply punctate, the punc-

tures distinctly separated throughout, finer toward the middle; base margined

with an extremely thick convex bead. Elytra oval, two and one-half times as

long as the prothorax and, in the middle, rather more than one-half wider ;

base truncate and equal to that of the prothorax; disk with nine unimpressed

series of very coarse deep punctures, the series obsolete at apical fourth ;

intervals from four to five times as wide as the serial punctures and excessively

minutely, sparsely and feebly punctate. Legs long and slender. Length

8.0-8.5 mm.; width 3.7-4.0 mm.

Texas (El Paso). Mr. Dunn.

The vibrisse near the apical thoracic angles are similar to those

of many Otiorhynchides; they appear to be generic and have not

been referred to in any published descriptions which I have seen.

This species differs from levis in its much more robust and

inflated elytra, coarser punctuation, more prominent apical angles

328 Coleopterological Notices.

of the prothorax, and more angulate frontal umbo; in levis the

elytral series become obsolete slightly behind the middle and are

composed of much finer punctures than in lecontei. In the very

large series of levis from various localities which I have before me,

there are indications of several more or less distinct varieties.

EPITRAGINI.

There seems to be a certain bond of affinity uniting the genera

Eurymetopon, Emmenastus, Auchmobius, Cnemodus, Epitragus,

Scheenicus, Chilometopon and Trimytis, which is expressed not

only by a general similarity of habitus, but also by important

structural peculiarities. The abdominal process for example is

acute or acutely rounded in all, the posterior cox, in a transverse

sense, are long, subparallel and linear, being also generally more or

less oblique, and the metasternum has a broadly interrupted trans-

verse groove,! parallel and very near to the posterior margin; this

groove becomes subobsolete only in a few aberrant species of

Emmenastus and in Trimytis,—both of which must be considered

as degradational types,—where it is represented by a series of finer

punctures which is generally more or less broadly impressed. The

wings are very exceptionally absent and are usually well developed.

In the opinion of the writer these genera should constitute, there-

fore, but a single tribe as named above, which may readily be sub-

_ divided into groups. The Epitragini are peculiarly American.

The Gnathosiini, comprising the genera Gnathosia, Stibia, Tri-

orophus, Triphalus, Pachychila, Anatolica, Tentyria, Microdera,

1 This groove, although possibly corresponding to the transverse metasternal

line of the Carabide, is not at all similar to it. In the case of the Carabide,

the line is perfectly continuous, and completely separates from the main body

of the metasternum a transversely triangular ‘‘ ante-coxal piece ;’’? here, how-

ever, there are really two independent grooves, which generally—though not

always—begin at the posterior margin near the inner side of the acetabulum,

and extend outward, parallel in curvature with its anterior edge, abruptly

terminating before attaining the episternum. The exact taxonomic value of

these grooves I have not ventured to determine, but they constitute a very

constant character throughout the greater part of the Tenebrionine, and the

Epitragini, in which they are also well developed, seem to approach that sub-

family in abdominal structure more closely than any other tribe not included

within its limits, for in some specimens, especially of Chilometopon, there

appears to be a rudimentary coriaceous margin at the middle of the third and

fourth ventral segments.

Coleopterological Notices. 329

Colposcelis, Calyptopsis, Capnisa and others, is distinguished by

the narrow but truncate abdominal process, the short broadly oval

and outwardly pointed posterior cox, a complete obliteration of

the metasternal groove, the entire and universal absence of wings,

and the thicker and denser integuments. In the genus Capnisa,

however, there is a feeble indication of the groove as a very fine

short impressed line opposite the inner part of the coxe ; this simply

denotes that Capnisa may have a remote line of affinity with some

other tribe, and is a matter of but little consequence when developed

to such a rudimentary degree. It will require but a short study

of the European genera, in conjunction with that of the single

genus Eurymetopon, to show-that the nature of the front is of

quite uncertain value in a tribal sense.

idrotes must be placed in a distinct tribe on account of its very

peculiar mesosternal structure, but I can perceive no great necessity

for separating Craniotus from the Gnathosiini, except it be the more

widely separated posterior coxe.' | Usechus should be united with

the Zopherini.

THINOBATES.

The two genera at present composing this group of the Epitragini,

as represented in the United States and Mexico, are both extremely

heterogeneous and are resolvable into some eight or nine distinctly

limited sections, which are at least of subgenerie value. All of the

species are more or less local and most of them extremely so; indeed

the entire genus Eurymetopon is very circumscribed in habitat,

being confined to the country bordering the Mexican boundary of

the United States to the westward of San Antonio in Texas, and

with its principal focus in southern Arizona. Emmenastus, how-

ever, is more widely diffused, extending from the southwestern parts

of the United States through Mexico and Central America and

1 The acute and prominent lateral lobes of the front, urged by Horn (Trans.

Am. Ent. Soc., 1874, p. 29) as an important tribal character, is apparently not

entitled to such rank ; the same difference can be observed between the front

of Epitragus submetallicus and EF. pruinosus ; the form of the metasternal epis-

terna also seems to have been given too great value in this connection. The

genus is quite abnormal, however, aud should certainly constitute an isolated

group of the tribe Gnathosiini.

be distinguished essentially as follows :—

Eurymetopon

Anterior tibiz normal, truncate at apeX ............eee eee eee EIMMenastus

EURYMETOPON Esch.

In this genus the transverse metasternal groove is always deep

and strongly developed, but becomes a little finer in section IIT.

In this connection it should be stated that the relative length of

the metasternum and first ventral seement, which is of considerable

importance in separating the species, sometimes varies slightly with

sex, the first segment being a little shorter in the female; this dif-

ference is however very insignificant, and does not affect the com-

parative measures as given in the table.

The antenne are remarkably uniform in structure throughout,

but have a slightly more abrupt and broader club in the subgenus

Cryptadius. The elytra are often much wider at base than the

contiguous base of the prothorax, a character unknown in Emmen-

astus.

The subgeneric sections may be defined as follows :—

It will be noticed that these three subgenera differ not only in

abruptly limited structural characters of unquestionable value, but

also in general habitus, the punctuation, for example, especially of

the pronotum, being of a distinctly different kind in each. The

California (San Bernardino and The Needles).

This is the form which has been regarded as rufipes and agrees

with the description of Eschscholtz, but I have never taken it near

San Francisco, which is the locality assigned it in the original

diagnosis, and do not think that it occurs there. In all probability

it belongs exclusively to the fauna of southern California.

A small subcylindrical species, allied in structural characters to

perforatum, but differing greatly in appearance. The types of

Arizona.

Although belonging to the rufipes section of the genus, this

species is not allied very closely to any other, and in some charac-

ters is intermediate between that group and convewxicolle. The

metasternum is much shorter than in dubium or rufipes, but longer

than in convexicolle, the distance from the posterior margin of the

coxa to the transverse groove being but slightly greater than the

length of the first ventral segment, while in the species mentioned

it is fully one-half longer than the segment. The pronotal punc-

tuation is finer than usual in this section of the genus, and the size

is much smaller.

parallel and very feebly arcuate, then strongly convergent and more strongly

arcuate in apical third; disk rather coarsely, deeply, somewhat sparsely punc-

tate toward the middle, much more coarsely, extremely densely but not very

confluently so laterally. lytra scarcely three times as long as the prothorax

and, behind the middle, nearly one-fifth wider ; sides rather strongly arcuate ;

apex broadly, very obtusely ogival; disk not very coarsely, rather feebly

punctate, somewhat confusedly near the suture, in approximate and more

asperate series laterally. Abdomen finely, feebly, sparsely punctate, more

coarsely, densely so laterally ; metasternum just visibly longer than the first

ventral segment. Legs moderate, the posterior tarsi unusually short, scarcely

two-thirds as long as the tibie. Length 6.5 mm.; width 3.2 mm.

Arizona.

The elytra are unusually inflated and the species may be readily

distinguished from any other by its convex form, alutaceous lustre

and peculiar coloration.

strongly convex, piceous-black, sometimes paler, shining. Head moderately

transverse, coarsely, deeply, perforately punctate, the punctures rather dense

but not contiguous; apex truncate, entire ; eyes moderate, very slightly more

prominent than the sides before them, the superior folds advancing well beyond

them and strongly arcuate; antenne rather slender, the third joint fully

three times as long as wide and much longer than the fourth. Prothorax from

four, to nearly five-fifths wider than long, the apex about five-sixths as wide

as the base, very feebly emarginate, the angles right and not blunt; base

transversely truncate, broadly, very feebly sinuate at each side of the middle,

the basal angles broadly obtuse but not at all rounded ; sides distinctly arcuate,

throughout, the punctures toward the sides gradually very closely crowded

and longitudinally confluent, but not much larger than those toward the

middle where they are usually separated by from once to twice their own

diameters. Elytra usually very slightly wider than the prothorax and rather

more than three times as long, generally about one-half longer than wide;

sides very feebly arcuate ; apex obtusely ogival; disk rather finely, sparsely

and irregularly punctate toward the suture, but much more coarsely and

asperately so laterally where the punctures are arranged in approximate

series, especially coarse and dense toward the humeri. Abdomen finely,

California (Barstow, San Bernardino and the Colorado Desert).

The series of eleven specimens exhibits considerable variation, not

only in color but in general form, but is not sufficiently extensive

to enable me to define any distinct varieties; the species may be

readily known by its robust, convex form, strongly transverse and

densely, very coarsely punctured pronotum. The hind wings are by

no means obsolete, although rudimentary ; they are broad, hyaline

and about two-thirds as long as the elytra, the latter subeonnate.

Eu. cylindricum n. sp.—Elongate, parallel, very strongly, cylindri-

cally convex, shining, the head very dull, black to piceous throughout. Head

transverse, truncate, generally finely and decidedly sparsely punctate, the

punctures sometimes rather coarse but always distant; eyes moderate, the

fold very acute, long and feebly arcuate; antenne rather slender, the third

joint but slightly more than twice as long as wide and only slightly longer

than the third. Prothorax from two-thirds to four-fifths wider than long, the

apex very feebly incurvate, the angles right and not at all blunt, the base

transverse, the two median sinuations very feeble; basal angles slightly

obtuse, not at all rounded and frequently very slightly prominent; sides

parallel and very feebly arcuate, more convergent and straighter in apical

lateral fourth, where the punctures become extremely coarse and deep, elon-

gate-oval and not very coalescent. Flytra equal in width to the prothorax

and about three times as long; sides parallel and nearly straight; apex

obtusely ogival; disk punctured nearly as in convezxicolle but more coarsely,

less densely and less asperately so laterally, and still more finely and sparsely

so toward the suture. Abdomen finely, sparsely punctate, the metasternum

from coxa to transverse groove distinctly shorter than the first ventral segment.

Legs slender. Length 6.5-7.5 mm.; width 2.7-3.4 mm.

California (Kern Co.).

This species is represented by a large series and cannot fail to be

easily recognized by the very peculiar punctuation of the pronotum,

subeylindrical form and more than usually elongate prothorax.

The punctures toward the sides of the pronotum are very abruptly

five or six times as large as those of the broad median portion, the

latter being very sparse as well as fine.

Eu. politum n. sp.—Elongate-oval, strongly convex, castaneous, highly

polished, feebly alutaceous toward the apex of the elytra. Head moderately

transverse, shining, entire and broadly truncate at apex, rather finely and

second elongate. Prothorax fully three-fourths wider than long, the apex

distinctly narrower than the base, just visibly emarginate, the angles slightly

obtuse but not in the least rounded; base transverse, with the usual feeble

median sinuations; basal angles obtuse, the apex rather acute, not in the

least rounded and just perceptibly prominent; sides evenly and,strongly

arcuate throughout; disk much wider in the middle than at base, convex,

rather finely and sparsely punctate, the punctures gradually becoming coarser,

about twice as large and dense but not coalescent toward the sides. Llytra

slightly wider than the prothorax and a little more than three times as long,

gradually rather acutely rounded behind; sides parallel and feebly arcuate ;

width across the humeri, which are narrowly rounded and not prominent,

quite distinctly greater than the base of the prothorax; disk convex, finely,

rather irregularly and sparsely punctured toward the suture, the punctures

very coarse and forming approximate series laterally where they are not per-

ceptibly asperate, except feebly so toward apex. Abdomen rather finely but

strongly, sparsely punctate, the metasternum between coxa and groove equal

in length to the first ventral segment. Legs slender, the femora rather robust,

polished, very minutely and extremely sparsely punctate ; posterior tarsi long

and slender, slightly shorter than the tibie. Length 6.5mm.; width 2.8 mm.

Texas (El Paso).

The single specimen which I took in loose sand, at the roots of

Coleopterological Notices. 339

some slender perennial plants growing near the banks of the Rio

Grande, represents a species which cannot well be compared with

any other here described. It is narrower and much more sparsely

punctate than convexicolle, and moreover differs from both that

species and ecylindricum in the much broader elytral base, with

exposed humeri, and in its shining head; in the two species men-

tioned the head is more transverse, and is rendered very dull by a

peculiar system of excessively minute but strong granuliform reti-

culations; in politum the reticulations are flat and much larger.

The metasternum in politum is slightly longer than in convewxicolle.

Eu. longipenne n. sp.—Oblong-elongate, parallel, moderately convex,

piceous-black ; under surface anteriorly, legs and antenne dark rufous ;

integuments subalutaceous. Head short and very transverse, broadly, arcu-

ately impressed anteriorly, the sides before the eyes rounded and broadly,

feebly reflexed, the epistoma transversely, feebly tumid and very broadly

arcuate between the emarginations which are broadly angulate and feeble ;

surface finely, densely punctate, the punctures shallow, annular and scabrous ;

eyes rather large, feebly prominent, the upper fold very short; antenne

slender, the third joint very elongate. Prothorax fully twice as wide as long,

the apex slightly narrower than the base, evenly, rather strongly emarginate

in circular arc, the angles acute and distinctly prominent ; base transverse,

with the usual two feeble approximate sinuations ; basal angles right, slightly

everted and distinctly prominent; sides very distinctly, rather evenly arcuate ;

disk distinctly wider behind the middle than at base, rather finely but dis-

tinctly, very densely punctate, without trace of median line, the punctures

scabrous, extremely dense and crowded laterally, the marginal bead very

acute and strongly elevated. lytra about one-fourth wider than the protho-

rax and about five times as long, wider across the humeri than any portion of

the prothorax, the humeri narrowly rounded ; apex obtusely rounded ; sides

straight and parallel; disk with distant and indistinct series of, small feeble

punctures, the series broadly, feebly and unevenly impressed ; intervals very

minutely, sparsely punctate. Abdomen feebly, the metasternum very finely

and sparsely punctate, the latter polished and nearly twice as long as the first

ventral segment. Legs long and slender. Length 9.2 mm.; width 3.5 mm.

New Mexico.

This well-marked species is the largest of the genus yet described,

and is very distinct in its long elytra, short prothorax, long meta-

sternum and several other characters. The anterior tibiew are

strongly, unevenly serrato-crenulate along the outer edge, and the

disk of the pronotum is very feebly impressed and more sparsely

punctate just before the scutellum.

not rounded and subprominent; base transverse, very feebly bisinuate in the

middle; basal angles very obtuse but not distinctly blunt; sides strongly

arcuate in the middle, feebly convergent and very feebly arcuate thence to the

Lower California (Cape San Lucas). Cab. LeConte.

In its distinct male sexual characters this species, so far as known,

stands alone; the male is larger than the female, more parallel, with

longer antenne, and has the apex of the fourth ventral segment

produced in the middle in a small feebly reflexed strongly rounded

lobe, extending slightly over the fifth. Although the elytra have

but slight traces of serial punctuation, the series are often indicated

.as broad dark streaks, due to the interference of light and the coarse

cellular structure of the inferior surface. Superficially, punctulatum

may be readily known by its very dull lustre and extremely dense,

almost even, pronotal punctuation.

Eu. histricum n. sp.—Oblong, parallel, rather strongly convex, piceo-

castaneous, slightly paler and more rufous beneath; integuments distinctly

alutaceous. Head short and very transverse, narrowed from base to apex,

finely, not very densely punctate, extremely densely so on the epistoma ;

apex truncate, the lateral emarginations very feeble, the lateral oblique

sutures however distinctly impressed ; eyes moderate, rather prominent, the

superior fold very strongly arcuate and almost attaining the lateral margin ;

antenne slender, the third joint very elongate. Prothorax three-fourths to

four-fifths wider than long, the apex slightly narrower than the base, evenly

but feebly emarginate, the angles rather acute and prominent; base trans-

verse, feebly bisinuate in the middle, the basal angles slightly obtuse, not in

the least rounded ; sides rather strongly, evenly arcuate, more convergent and

straighter near the apex; disk feebly, transversely impressed just before the

base, rather longitudinally convex, somewhat finely but strongly, sparsely

punctate, the punctures becoming gradually coarser, scabrous and extremely

thorax and about three and one-half times as long, at base but just visibly

wider than the contiguous base of the latter, the humeri very slightly exposed,

obtusely subangulate; apex broadly, obtusely rounded; sides parallel and

straight, feebly convergent and arcuate toward the humeri; disk with distant

punctate. Abdomen finely punctate; metasternum very densely punctate later-

ally, fully one-half longer than the first ventral segment. Legs slender.

Length 7.3-7.7 mm.; width 3.2 mm.

Arizona.

This species is to be placed near muricatulum, but differs greatly

in its more robust and convex form, alutaceous lustre and very

much denser, coarser and more coalescent punctuation toward the

sides of the body. The lateral emarginations of the epistoma are

very feeble; they are normally developed in muricatulum.

Eu. muricatulum n. sp.—Oblong, elongate, subparallel, moderately

convex, shining, piceous-black ; under surface, legs and antenne dark rufous.

and with two very feeble distant emarginations ; surface finely, rather feebly,

somewhat densely and submuricately punctate; eyes moderate, rather dis-

tinctly prominent ; antenne long and slender, the third joint very elongate,

the fourth shorter. Prothorax three-fourths to four-fifths wider than long ;

apex slightly narrower than the base, feebly, evenly but distinctly emargi-

nate, the angles not at all rounded, slightly obtuse when viewed laterally but

acute and prominent vertically ; base transverse, with the two approximate

median sinuations rather pronounced; basal angles obtuse, not rounded ;

sides moderately arcuate, more convergent anteriorly; disk a little wider

slightly behind the middle than at base, very finely, sparsely punctate, with

a narrow impunctate line, the punctures becoming gradually coarser and

muricate but still small and rather well separated laterally. Elytra somewhat

distinctly wider than the prothorax and four times as long or slightly less;

Arizona (Benson). Mr. Dunn.

This species, which is represented by a good series, is allied only

to histricum, but is more slender and much more polished. A

portion of the series was communicated by Mr. Dunn as having

been taken at E] Paso, Texas, but I am inclined to think that they

were all taken at the locality indicated. The sexual characters are

not distinctly pronounced.

Eu. discors n. sp.—Oblong-elongate, parallel, moderately convex, rather

shining, castaneous throughout; integuments thin; wings well developed.

Head nearly as in longipenne, but less impressed and with the broad, indefi-

nite, transverse tumidity of the epistoma more acute and cariniform. Protho-

rax just visibly less than twice as wide as long, the apex much narrower than

the base, moderately emarginate, the angles right, not rounded and slightly

prominent; base truncate, feebly bisinuate in the middle, the basal angles

very broadly obtuse but with the extreme apex right and slightly prominent,

the sides before them broadly and very feebly sinuate; sides very strongly

arcuate and strongly convergent toward base and apex ; disk much wider at or

a little behind the middle than at base, very obsoletely impressed just before

the scutellum and with a feeble impressed median line; punctures scabrous,

rather fine and decidedly sparse toward the middle, coarser, much denser but

still not very crowded laterally ; marginal bead moderate in elevation, very

thin, the outer edge very finely and feebly serrulate especially anteriorly.

Elytra but very slightly wider than the prothorax and between four and five

times as long, across the humeri about equal to it in width, and much wider

than its base, the humeri narrowly rounded ; apex broadly, obtusely rounded ;

sides parallel and subrectilinear; disk with series of broad, very feeble, im-

pressed sulcations and equally wide intervals, very finely, not very densely,

subasperately punctate throughout, with vaguely defined series along the

middle of the sulci. Abdomen extremely minutely, the metasternum finely

but distinctly, rather sparsely, punctate, the latter between coxa and groove

scarcely one-half longer than the first ventral segment ; ventral segments long.

Length 6.7-7.8 mm.; width 2.€-3.2 mm.

Texas (El Paso).

The peculiar feeble suleation of the elytra is similar to that of

longipenne, but more pronounced; on the other hand, however,

the series of punctures are much less definite than in that species.

Discors is related to longipenne, but differs in the much more

arcuate sides of the prothorax, sparser punctuation, smaller size,

relatively narrower and shorter elytra, much shorter metasternum,

and in the presence of an impressed median line on the pronotum ;

this line is very feeble and may sometimes be scarcely traceable.

There is no trace of an impunctate median line in either discors or

longipenne.

Eu. debile n. sp.—Oblong-oval, moderately convex, piceous-black, the

legs and antenne dark rufous; integuments rather dull, the elytra more

shining. Head moderately narrowed from base to apex, the sides before the

eyes feebly arcuate; median lobe at apex very slightly produced, broadly

truncate, the emarginations very small but distinct; eyes moderate; surface

finely, extremely densely punctate throughout; antenne slender. Prothorax

about three-fourths wider than long; apex slightly narrower than the base,

evenly and strongly emarginate in circular arc, the angles right, not at all

rounded and anteriorly prominent; base transverse, extremely feebly sinuate

at each side of the middle; basal angles rather obtuse but not at all rounded ;

sides nearly evenly and moderately arcuate; disk rather convex longitudi-

nally, with the feeblest trace of a fine, elevated, median line, finely, densely

punctate, the punctures scabrous and extremely densely crowded toward the

sides, very dense but distinctly separated toward the middle, not at all im-

pressed although very sparsely punctate in a small area opposite the scutellum.

Elytra nearly one-fourth wider than the prothorax and rather more than three

times as long, across the humeri a little wider than any portion of the disk

of the latter, the humeri broadly exposed and very narrowly rounded ; apex

obtusely rounded ; sides parallel and nearly straight; disk with extremely

confused, approximate, unimpressed rows of somewhat coarse, subscabrous

and rather approximate punctures. Abdomen very finely and sparsely punc-

tate; metasternum between coxa and groove nearly one-fourth longer than

the first ventral segment. Legs slender, the posterior tarsi much shorter than

the corresponding tibie. Length 5.6 mm.; width 2.5 mm.

Arizona (Peach Springs), Mr. Wickham.

This distinct species is allied to punctulatum and longipenne,

but is very much smaller; from crassulum and sodalis it may be

readily known by its widely exposed humeri and more depressed

form. It is a connecting link between the larger species of this

section, with very long metasternum, and the small very convex

species with shorter metasternum.

Texas (El Paso); Arizona.

This species, which is represented before me by an ample series,

is one of the smallest of the genus and is remarkable for its very

convex, subcylindrical form and dense punctuation. It differs from

sodalis, to which it is allied, in its much smaller size and narrower

form, larger head which is more strongly narrowed from base to

apex, in its denser duller and darker integuments, and prominent

thoracic angles. The median lobe of the front is narrower and the

lateral lobes much broader than in sodalis.

In these small species the basal bead of the pronotum and its

corresponding fine groove are more pronounced than in the others.

punctate. Prothorax about two-thirds wider than the head and twice as wide

as long; apex considerably narrower than the base, evenly and distinctly

emarginate in circular arc, the angles obtuse, not at all rounded but not very

prominent; base transverse, very feebly lobed in the middle, the basal angles

extremely obtuse and rather blunt; sides strongly arcuate, straighter and

more convergent toward apex; disk much wider behind the middle than at

base, with obsolete traces of a fine elevated median line and a small foveiform

impression just before the scutellum, rather coarsely but feebly and roughly

punctate laterally, the punctures slightly separated, finer and decidedly

sparse toward the middle; lateral edges finely but distinctly serrulate and

with short erect sete. Elytra slightly wider than the prothorax and rather

less than four times as long; humeri but slightly exposed, rounded; apex

parabolically rounded; sides feebly arcuate; disk with rather well defined,

unimpressed, approximate rows of punctures, the latter becoming finer, sparser

As usual throughout this section of the genus the anterior tibiz

are finely serrato-crenulate externally. One specimen in the cabinet

by Mr. L. Allgewahr, indicates a very exceptional range for this

California (San Diego).

A most interesting and aberrant species which is very certainly

entitled to subgeneric distinction, the characters relating to the

front as given in the table differing from those of Telabis to a

remarkable degree.

In two of the specimens before me, which are perfectly black,

there are no traces whatever of serial arrangement of the elytral

punctures, but in three others, which are uniformly pale ferrugi-

nous, there are very feebly defined lateral series in which the punc-

tures are more densely but irregularly aggregated. Although there

are, practically speaking, no distinct series, the elytra bear distinct

traces of the very feeble longitudinal impressed lines, so often

noticeable throughout the Epitragini.

Undetermined Species.

Eu. ochraceum Esch.

The description of Mannerheim is as follows :-—

“‘Oblongum, pallide ochraceum, capite paulo obscuriore, thorace subeylin-

drico, elytris medio gibbosis posterius declivibus, subtiliter striato-punctatis,

punctis basi et apice evanescentibus, interstitiis remote punctulatis, punctis

subseriatis.

** Longit. 14 lin.

** Habitat in California ad St. Franzisco, sub lapidibus.”’

If this description is correct it cannot refer to any known species

of EKurymetopon. The length as given indicates a very small

species, smaller than the smallest known specimen of Emmenastus,

and in the latter genus the elytral punctures, although frequently

feebler or evanescent near the apex, are never so to the least degree

toward base; they are on the contrary almost invariably stronger

toward base especially near the humeri.

It will be readily observed that these sections are of more than

usual importance, and if not generic are at least entitled to full

subgeneric recognition. I have not given them distinctive names,

however, as the very extensive Mexican contingent will probably

add several others, and the mutual relationship and limitation of

348 Coleopterological Notices.

the various subgenera can be adequately appreciated only in a

general monograph.

The metasternum! is usually longer in those species having well-

developed wings, but this difference is not always very pronounced,

The metasternal groove is as usual widely interrupted opposite the

abdominal process and becomes obliterated before attaining the

episterna. This groove has but little definite systematic value in

Emmenastus other than specific. In section I it is always very

strong and well developed, also in the single representative of

section III, while in section II it is well marked in some species

and more or less rudimentary in others, and, although in section IV

it is generally almost obsolete, its tendency to appear is frequently

indicated by a-.feebly impressed line of close irregularly placed

punctures.

The sections as defined above are quite homogeneous with the

exception of IT, which is still rather composite although in charac-

ters of minor value, the individual species being in every instance

widely isolated; they are much more persistent in type in sections

I and [V. In section IV the hind wings appear to be constantly

present but are always very rudimentary ; in obesus, for example,

they consist of an extremely small semi-membranous plate, scarcely

more than one-fourth as long as the prothorax, and in ater of a very

slender fillet of similar structure about as long as the prothorax.

In this section the apical margin of the head is not truncate but

broadly, more or less evenly arcuate and entire. In piceus and

pinguis there are two small distant feebly developed emarginations,

somewhat similar to those of Eurymetopon, but here they have no

systematic value whatever, and are not approached by or connected

in any way with the mandibles; the margin is almost invariably

entire, and these exceptions appear to be rather in the nature of

accidental and meaningless aberrations.

The known species occurring within the limits of the United

States, including Lower California where they appear to be especi-

ally abundant, may be distinguished as follows :—

1 In estimating the length of the metasternum and first ventral seement, the

distances are measured on a longitudinal line passing through the cox, thus

representing the minimum length of each, and include the entire metasternum,

as the groove frequently becomes obsolete in this genus.

nent than the sides before them, they are much less so than in

marginatus.

In common with all the winged species except longulus, the pre-

sent appears to be quite rare and I have seen only the unique type.

E. marginatus n. sp.—Oblong, parallel, somewhat depressed, dark

rufo-testaceous, the legs and antenne paler and more flavate; integuments

highly polished throughout. Head short and broad, rather coarsely, densely

punctate; sides rapidly convergent from base to apex, the eyes large, very

convex and very much more prominent than the sides of the head; epistoma

narrow at apex, rather feebly but distinctly sinuate ; supra-orbital ridges fine

but distinct, extending well beyond the eyes, obsolete at the middle of their

upper margin; antenne slender, with a loose elongate club. Prothorax fully

four-fifths wider than long, the apex rather distinctly narrower than the base,

distinctly emarginate in circular arc, the apical angles rather acute and not

at all rounded ; base transverse, very feebly sinuate at each side of the middle,

the angles slightly obtuse but not at all rounded; sides evenly and moderately

arcuate; disk very slightly wider just behind the middle than at base, coarsely,

rather densely punctate, the punctures becoming gradually longitudinally

confluent toward the sides, the latter very narrowly but distinctly explanate.

Elytra about three and one-half times longer than the prothorax and subequal

to it in width, very slightly wider behind; apex ogival; sides subparallel,

very slightly more arcuate behind ; disk with feebly but distinctly impressed

strie, which extend unbroken almost to the apex, the strie rather coarsely

and very approximately punctured, the intervals flat, each with a moderately

even series of distinct but smaller punctures, those of the sutural interval

confused. Abdomen finely very sparsely punctate, the surtace slightly scabrous

and the punctures larger and closer near the sides. Legs long and slender,

the posterior tarsi almost as long as the tibie. Length 6.5 mm. ; width 2.8mm.

Lower California.

A very distinct species, peculiar in its very prominent eyes; in its

impressed elytral striz it somewhat resembles texanus, but differs

greatly in the structure of the epistoma.

a very fine cariniform bead. Scutellum minute, transverse. E/ytra about

three and one-half times longer than the prothorax and very slightly wider,

the two bases equal in width; apex ogival; disk with unimpressed rows of

shallow, rounded approximate punctures, generally moderate in size but be-

extending to the apex ; intervals flat, each with a single quite regular line of

very fine feeble punctures, those of the sutural interval generally more irregu-

larly disposed. Abdomen very finely, feebly and sparsely punctate. Legs

slender, the posterior tarsi but just visibly shorter than the tibie. Length

California (Los Angeles, Pomona and San Diego); Arizona.

The metasternum is scarcely perceptibly longer than the first

ventral segment, and is feebly, very sparsely but rather coarsely

punctate, the episternum similarly punctate. The transverse meta-

sternal groove is strongly impressed.

A very common species, readily known by its slender parallel and

rather convex form, very shining surface, and evenly and abruptly

rugulose lateral portions of the pronotal disk. The hind wings are

very well developed, being rather longer than the elytra.

E. angustus n. sp.—Very elongate-oval, moderately convex, very pale

castaneous, strongly shining but not polished, the elytra distinctly alutaceous

intervals unevenly, finely, feebly and sparsely punctate, the punctures form-

ing moderately even single series only in the lateral intervals. Abdomen finely,

feebly punctate, the punctures sparse but much denser and more rugulose

near the sides. Legs very slender, the posterior tarsi much shorter than the

tibie. Length 6.8 mm.; width 2.6 mm.

Arizona.

The metasternum is quite perceptibly longer than the first ventral

segment and is rather densely but not very coarsely punctate, the

episternum densely punctured. This species is allied to longulus,

but differs considerably in the longer prothorax, widest at or near

the base and with the sides feebly arcuate, in the duller, more scab-

rous and more finely punctate elytra, with confusedly punctate

intervals, in its shorter, broader head, with distinctly larger eyes,

and in its paler, apparently thinner and more coriaceous integu-

ments, being allied in this character more nearly to fexanus.

Although the punctuation toward the sides of the pronotum is

very confluent and scabrous, it does not form the long, even and

unbroken ruge which are so characteristic of longulus.

E. piceus n. sp.—Oblong, rather robust and convex, parallel, piceous-

black ; legs and under surface paler, rufo-piceous ; integuments feebly aluta-

ceous. Head moderately transverse, rather finely, not very densely, rugulosely

punctate, the punctures of the epistoma much denser, deeper, rounded and

not rngulose; apex broadly, feebly, angularly emarginate at the extremities

of the epistomal suture; apex subtruncate; eyes rather large, but just per-

ceptibly more prominent than the sides of the head; antennz rather long,

moderately slender, the eighth joint much longer than wide. Prothorax short,

nearly twice as wide as long, the apex very feeble emarginate and but slightly

more than three-fourths as wide as the base, the latter transverse, broadly

and very distinctly sinuate at each side of the median lobe; basal angles

slightly obtuse, the apical right, both without trace of rounding ; sides evenly

and rather strongly arcuate, the disk widest at about basal third, rather finely

and sparsely punctate, the punctures gradually dense and semi-confluent

toward the sides, the latter with a very fine acute marginal bead. Llytra

three and three-fourths times as long as the prothorax and very slightly

wider, the sides very feebly, evenly arcuate throughout, broadly ogival at

apex; disk with unimpressed rows of rather small, rounded, shallow punc-

tures which are separated by about twice their own diameters, not much larger

toward the humeri, the series disappearing in confused punctures before attain-

ing the apex ; intervals with moderately even single rows of extremely small,

widely distant punctures. Abdomen extremely finely, sparsely punctate, the

punctures becoming quite coarse and denser near the sides. Legs moderate in

length, the posterior tarsi distinctly shorter than the tibie. Length 5.7 mm.;

width 2.4 mm.

California (San Bernardino Co.).

This species is quite distinct, differing from longulus in the feeble

emarginations at the sides of the epistoma, in the much less rugu-

lose sides of the pronotum, in the finer and more abbreviated elytral

series, in its feebly alutaceous lustre and in its shorter, broader

prothorax, as well as its generally shorter and more robust form.

The anterior tibize are perfectly simple and without trace of out-

ward extension at apex.

E. discretus n. sp.—Elongate-oval, very convex, highly polished, dark

blackish-castaneous ; under surface, legs and antenne dark rufo-testaceous.

Head transverse, rather finely and not very densely punctate, the punctures

very dense toward the apical margin; eyes moderate, the ridges fine but

strong; antenne very slender, the club feeble and elongate, all the joints

much longer than wide, the eleventh widely fusiform, a little narrower and

longer than the tenth. Prothorar scarcely two-thirds wider than the head,

two-thirds to three-fourths wider than long, the apex about four-fifths as wide

as the base, feebly emarginate in circular arc, the angles varying from right to

very slightly acute, not rounded ; base broadly, distinctly bisinuate, the basal

angles right, not at all rounded and extending posteriorly distinctly further

than the median lobe ; sides feebly arcuate, straighter toward base and apex ;

disk transversely strongly convex, extremely feebly so longitudinally, rather

strongly, deeply, irregularly and sparsely punctate, the punctures somewhat

abruptly rather coarser and longitudinally coalescent near the sides, forming

prominent interlacing ruge. Elytra evenly oval, in the middle about one-

fourth wider than the prothorax, not more than three times as long, the two

bases equal in width but not completely coarctate; disk with distant, unim-

pressed series of punctures which do not quite attain the apex and which are

not traceable toward the suture, the punctures rather approximate, much

larger and closer toward the humeral regions, very fine toward the suture ;

intervals flat, rather sparsely, confusedly punctate, the punctures closer and

larger toward the sides near the base. Abdomen minutely, rather sparsely

punctate, abruptly coarsely scabrous and duller near the sides. Legs decidedly

short but very slender throughout, the posterior tarsi a little shorter than the

tibie. Length 5.9-6.2 mm.; width 2.8-3.0 mm.

here described, but should be associated with conicicollis because

of its strongly bisinuate base of the prothorax.

E. conicicollis n. sp.—Elongate-oval, strongly convex, polished, black,

the under surface, legs and antenne dark rufo-piceous. Head moderate, rather

finely, deeply and densely punctate, the punctures much more crowded ante-

riorly ; eyes moderate, scarcely perceptibly more prominent than the sides

before them; epistoma broadly subtruncate ; antenne long and slender. Pro-

thorax about three-fourths wider than long, trapezoidal in form, the apex but

slightly more than two-thirds as wide as the base, very feebly emarginate in

circular arc, the apical angles right, not in the least rounded ; base transverse,

broadly and very distinctly bisinuate, the basal angles right and very narrowly

rounded, not at all prominent posteriorly ; sides evenly convergent from near

the base to the apex and almost straight, feebly arcuate near the base; disk

widest a very little before the base, finely, very sparsely but distinctly punc-

tate, the punctures becoming much coarser, very dense and semi-coalescent

near the sides, the marginal bead very fine, not very strongly elevated cr

acute, becoming a very little more prominent near the base. lytra parallel,

equal in width throughout to the prothorax and barely three times as long,

rather abruptly broadly angulato-parabolic at apex; disk with unimpressed

series of small, rather feeble but very approximate punctures which become

rather confused near the apex, the intervals flat, very minutely, sparsely and

irregularly punctured. Abdomen extremely minutely and very sparsely punc-

tate, the punctures becoming coarse but not very dense near the sides. Legs

slender, the femora not robust; posterior tarsi not quite as long as the tibie.

Length 6.2-7.0 mm. ; width 2.7-3.1 mm.

Arizona.

The metasternum is, if anything, a little longer than the first

ventral segment, coarsely, rather densely punctate in the anterior

half, extremely minutely and sparsely so thence posteriorly to the

transverse groove, which is well developed although obsolete as

usual in the middle and not attaining the episterna.

This species is not closely allied to any other; subopacus which

has a somewhat similarly shaped prothorax, has more inflated elytra,

a straight transverse pronotal base and very dull lustre.

anteriorly ; eyes moderate, barely more prominent than the broadly rounded

sides before them ; epistoma subtruncate or very feebly sinuate ; antenne long

gent toward apex ; disk very slightly wider behind the middle than at base,

very finely, densely punctate, the punctures denser but not coarser laterally

where they are usually distinctly and longitudinally rugulose or coalescent ;

surface strongly convex longitudinally as well as transversely. £lytra sub-

rather sparsely punctate, generally finely, feebly, longitudinally rugulose ;

punctures rather coarse toward the sides. Legs moderate in length, the

femora somewhat robust; posterior tarsi rather distinctly shorter than the

Texas; New Mexico; Arizona.

The metasternum is exactly equal in length to the first ventral

segment, the transverse groove very well developed and the body

totally apterous.

This species is very abundantly diffused through the regions

indicated, but does not seem to extend to the westward of the

Colorado River. The series before me is very extensive, consist-

ing of forty-two specimens and indicates but slight variability ; in

one abnormal specimen, however, the sides of the prothorax are

very broadly and feebly sinuate anteriorly.

For some unaccountable reason convexus has been heretofore

confounded with the Californian obesus, a species distinct in all of

its characters and belonging to a different section of the genus.

My comparisons have been made from the original types of both.

E. subopacus Horn.—Trans. Am. Phil. Soc., XIV, p. 269.—Suboval,

nearly straight in basal two-thirds, the eyes moderate, not at all prominent ;

apex broadly, very feebly sinuate, not emarginate laterally ; surface rather

finely but strongly, very densely punctate; antenne long, slender, the eighth

joint nearly one-half longer than wide. Prothorax trapezoidal, three-fifths wider

than long; apex about three-fourths as wide as the base, broadly, extremely

feebly sinuate, the angles right, narrowly but very distinctly rounded ; base

truncate and perfectly straight, the basal angles right and distinctly rounded ;

with a very fine acute bead. Llytra about three times as long as the prothorax

and, in the middle, fully one-fifth wider; sides parallel and broadly but dis-

tinctly arcuate, almost continuous in direction with those of the prothorax ;

apex broadly ogival; disk with distant, unimpressed rows of rather small but

very distinct, rounded and approximate punctures which continue to the apex

but become very indistinct; intervals flat, extremely minutely, sparsely and

irregularly punctate. Abdomen very finely, feebly rugulose, minutely but not

very sparsely punctate. Legs slender, the posterior tarsi much shorter than

the tibie. Length 7.5 mm.; width 3.3 mm.

Arizona.

The metasternum is very coarsely, strongly and rather densely

punctate, the punctures distinctly separated and variolate, with the

transverse groove apparently well developed ; it is distinctly shorter

than the first ventral segment.

The trapezoidal form of the prothorax, the form of the body

which is gradually narrowed in front from the middle of the elytra,

the rounded prothoracic angles, dull lustre and very minute punc-

tures of ‘the strial intervals, will at once distinguish this species

from any other of our fauna.

E. pimguis Lec.—N. Spec. Col., 1866, p. 107.—Broadly elliptical, rather

strongly convex, dark rufo-ferruginous throughout, decidedly alutaceous in

lustre. Head short and transverse, rather finely, very densely punctate ; apex

transversely truncate, with a small feeble angulate emargination on each side

at the suture ; eyes moderate, the external outline oblique but uearly straight,

posteriorly divergent, the base coincident and equally prominent with the

short tempus visible behind, but more prominent than the sides before them

which are strongly rounded for a short distance, the fine fold or ridge short

but distinct; antenne long and very slender. Prothorax two and one-fourth

times as wide as long, the apex scarcely two-thirds as wide as the base,

very distinctly emarginate in circular arc, the angles slightly obtuse but not

rounded ; base transverse and truncate throughout, with excessively feeble

traces of the broad lateral sinuations ; basal angles obtuse and very distinctly,

rather broadly rounded ; sides strongly arcuate toward base, nearly straight

and convergent anteriorly ; disk scarcely perceptibly wider a little before the

base, rather finely but strongly and very densely, uniformly punctate through-

out, the punctures more crowded but not distinctly tending to coalesce laterally,

the surface very feebly subexplanate near the sides which are very minutely

and rather feebly beaded. Llytra just visibly wider than the prothorax and

between three and four times as long, the sides very feebly arcuate, the apex

broadly parabolic; disk finely, somewhat sparsely punctate and without trace

Lower California (Cape San Lucas). Cab. LeConte.

The metasternum is rather coarsely deeply and somewhat densely

punctate throughout, about three-fourths as long as the first ventral

segment and with the transverse groove apparently obsolete.

A very peculiar and isolated species in its short broad densely

punctate prothorax and total absence of series of punctures on the

elytra. The eyes in pinguis are very different in structure from

those of punctatus, for in the latter they stand out from the head

in bold relief, the tempora behind them being totally obsolete.

Lower California (Cape San Lucas). Cab. LeConte.

The metasternum is about three-fourths as long as the first ven-

tral segment, and is uniformly very coarsely but sparsely and feebly

punctate, the transverse groove very deeply excavated.

Punctatus is a very distinct form, of larger size than usual, and

remarkable in the coarse densely hairy vestiture of the tarsi, very

prominent eyes, as well as the bisinuate base of the prothorax; the

last of these peculiarities it however possesses in common with

conicicollis and discretus. In both the latter species the tarsi are

sparsely clothed beneath with short spinose sete as usual. The

elytral striz become very feebly impressed toward apex.

California (San Diego).

The metasternum is deeply, coarsely punctate, fully three-fourths

as long as the first ventral segment, and the transverse groove is

only suggested by a broadly and very feebly impressed line of un-

evenly placed punctures. The series before me consists of ten

may be known at once by the very broadly and distinctly, although

moderately, impressed striz.

California (Napa and Sonoma Cos.).

One of the larger of the species having short robust antenne, and

readily distinguishable by the very distinctly arcuate sides of the

prothorax, convergent toward base, and the broadly obtuse but not

rounded basal angles. It is rather local and not abundant.

The metasternum is scarcely three-fourths as long as the first

ventral segment; the basal groove is widely interrupted in the

middle, disappearing in a row of punctures at lateral fourth.

Length 4.5-5.3 mm. ; width 2.0—2.3 mm.

California (San Francisco).

This is a plentiful species near the coastline of middle California,

and the description refers to the typical form. The specimen marked

“?S8. D.” in the Cabinet of LeConte, which is referred to in the

original description, differs only in haying the punctures of the

principal series a little larger, deeper and less approximate; it is

not specifically distinct and the locality is probably erroneous. I

have, however, a single specimen which was taken by me in the

Sierras at Truckee, which seems to indicate an extremely closely

allied species, having a slightly less transverse prothorax, with the

basal angles very small and slightly prominent, also anotber single

specimen taken at San Francisco, which is distinctly larger than

any other of the fifteen examples, with a distinctly longer, much

more sparsely punctured prothorax; the length of this specimen is

5.8 mm.; both those last referred to are probably specifically distinct.

E. fallax n. sp.—Oblong-oval, very strongly convex, rather distinctly

shining but not strongly polished, very slightly alutaceous near the elytral

apex; color dark castaneous-brown, the under surface, legs and antenne

paler, rufo-ferruginous. Head moderate, broadly rounded at apex, finely,

deeply and very densely punctate, the eyes and antenne as usual. Prothorax

rather more than three-fourths wider than long, the apex very distinctly nar-

rower than the base, feebly, evenly sinuate in circular arc, the angles right

and very narrowly rounded ; base truncate, the angles obtuse but not rounded ;

sides moderately arcuate, more convergent and rather straighter toward apex ;

disk slightly wider just behind the middle than at base, not very finely, very

deeply, perforately and densely punctate, the punctures very slightly less

dense toward the middle. £lytra nearly three times as long as the prothorax

and, in the middle, quite distinctly wider; sides parallel and feebly arcuate ;

New Mexico (Santa Fé). Miss M. W. Greene.

A robust and very convex species, bearing a deceptive external

resemblance to convexus, but easily distinguishable by the charac-

ters given in the table.

E. thoracicus n. sp.—Oblong, rather strongly convex, dull and aluta-

ceous, dark piceo-castaneous throughout, smooth. Head moderate, transverse,

broadly, rather strongly arcuate at apex, finely, deeply, very densely punc-

tate, the eyes small and antenne robust. Prothorax about four-fifths wider

than long, the apex slightly narrower than the base, almost transversely

truncate, being just perceptibly incurvate, the angles very slightly obtuse

and rather broadly rounded; base truncate, the basal angles very obtuse but

not rounded and not in the least prominent; sides parallel, very strongly,

evenly rounded in circular arc from base to apex; disk much wider in the

middle than at base, finely, deeply and very densely punctate, the punctures

equally dense throughout the width, the lateral bead extremely fine. Elytra

equal in width to the prothorax and three times as long, the sides parallel

and just perceptibly arcuate, the apex rather obtuse; disk with very feebly

impressed striz of small but deep and very approximate punctures, the series

not attaining the extreme apex; intervals flat, very finely, rather sparsely

and irregularly punctate. Abdomen rather coarsely and densely punctate

throughout the width. Legs moderate, the posterior tarsi much shorter than

the tibie. Length 6.6 mm.; width 2.6 mm.

California (San Gorgonio Pass?)

The metasternum is just visibly shorter than the first ventral

segment, rather coarsely, deeply, very densely and conspicuously

punctate, the usual transverse groove indicated by a very broadly,

feebly impressed series of smaller and unevenly placed punctures.

This is one of the most distinct species of this section of the

genus, distinguishable at once by the very strongly arcuate sides

and obtuse basal angles of the prothorax and finely, evenly punc-

tured disk; the very feeble impression of the elytral series may

possibly be an accidental characteristic of the unique example, but at

all events the series themselves are much more distinct than usual.

polished, black, the antenne black; legs very dark rnfo-piceous. Head

nearly two-thirds as wide as the prothorax, rather transverse, broadly arcuate

throughout at apex, rather convex, finely, deeply and densely punctate; eyes

small, the folds short but very distinct; antenne short and robust. Prothorax

quite distinctly rounded ; base truncate, the angles extremely obtuse and just

visibly rounded or blunt; sides evenly, very strongly rounded in circular are

from base to apex; disk very much wider in the middle than at base, very

strongly convex longitudinally as well as transversely, rather coarsely, very

deeply and densely punctate, the punctures distinctly separated toward the

middle, the marginal bead extremely fine and feeble. Elytra oval, fully three

times as long as the prothorax and, in the middle, not very distinctly wider ;

sides parallel, broadly and distinctly arcuate; apex broadly parabolic; disk

with unimpressed and distant series of somewhat approximate and rather

deeply impressed punctures, confused near the apex where the punctures are

finer and the surface dull; intervals finely, sparsely but distinctly punctate,

the punctures irregularly disposed but tending to a uniserate arrangement

laterally. Abdomen finely, sparsely but very distinctly punctured. Legs

moderate. Length 5.6-6.0 mm. ; width 2.2—2.4 mm.

Arizona (Seligman and Cafion Cosnino). Mr. Wickham.

This species is quite distinct in its very obtuse basal angles of

the prothorax and strongly arcuate sides of the latter.

E. crassicornis n. sp.—Oblong-elongate, broadly convex, parallel,

smooth but very dull, black, the legs and antenne dark rufous. Head nearly

as in obtusus. Prothorax fully three-fourths wider than long, the apex nearly

five-sixths as wide as the base, broadly and extremely feebly sinuate, the

angles right and very narrowly rounded ; base transversely truncate; basal

angles acute, prominent and not at all rounded; sides feebly arcuate and

convergent anteriorly, nearly straight and parallel posteriorly and distinctly

sinuate very near the base; disk not very finely but deeply and very densely

punctate, the punctures generally separated by from once to twice their own

diameters, but becoming gradually extremely dense and crowded although not

exactly in contact in lateral third; marginal bead very fine but distinct.

Elytra subequal in width to the prothorax and about three times as long ;

sides parallel and scarcely visibly arcuate posteriorly ; apex narrowly rounded ;

disk punctured as in obtusus. Abdomen very finely and sparsely punctate, the

punctures becoming larger but not very coarse laterally. Legs nearly as in

obtusus. Length 6.0 mm.; width 2.7 mm.

California (Hoopa Valley, Humboldt Co.).

This species in general appearance somewhat resembles obtusvus,

but differs in its still duller and very opaque integuments, more

parallel and less arcuate sides and less strongly emarginate apex of

the prothorax, the latter being more transverse, rather more coarsely

and densely punctate and with the basal angles acute and slightly

everted ; the pronotum is less longitudinally convex, and the entire

body is more parallel,

E. coarcticollis n. sp.—Oblong-oval, black, strongly convex, highly

polished throughout. Head small, about one-half as wide as the prothorax,

wider than long, rather convex, finely, deeply and densely punctate ; epistoma

broadly, very distinctly and evenly arcuate at apex; eyes small, the upper

fold extremely short and feeble; antennz short, very robust. Prothoraxr twice

as wide as long, the apex five-sixths as wide as the base, evenly, feebly but

distinctly emarginate in circular arc; base truncate, the basal angles slightly

obtuse, small, not at all rounded and distinctly prominent; sides rather

strongly arcuate, more convergent and straighter anteriorly, distinctly but

broadly sinuate before the base; disk much wider at basal third than at

base, finely, rather sparsely punctate near the middle, the punctures becom-

ing slightly larger and very dense but not coalescent laterally. Elytra nearly

three and one-half times longer than the prothorax and, in the middle, very

distinctly wider, ovoidal, acutely rounded at apex; sides parallel and very

distinctly arcuate; disk very convex, with distant, unimpressed rows of small,

moderately close-set punctures which are distincly traceable throughout the

width and continuing nearly to the apex; intervals sparsely and more finely

punctate, the punctures confused near the suture but tending to a uniseriate

arrangement thence to the sides. Abdomen polished, finely, sparsely punctate,

coarsely so near the sides. Length 4.8 mm.; width 2.1 mm.

New Mexico (Fort Wingate). Dr. Shufeldt.

This small species is allied to acutus, but differs in its much

shorter more transverse prothorax and distinct elytral series, also

in its smaller head and slighter coarser punctuation.

KE. acutus Horn.—Trans. Am. Phil. Soc., XIV, p. 270.—Oblong-oval,

more or less inflated behind, strongly convex, polished, the elytra becoming

gradually dull toward apex, black, the legs dark rufous. Head moderate,

fourths wider than long, the apex fully four-fifths as wide as the base, just

visibly incurvate in circular arc, almost truncate, the angles right and slightly

blunt; base truncate, the angles small, right, not at all rounded and distinctly

prominent; sides almost evenly and rather strongly arcuate, abruptly and

distinctly sinuate for a short distance before the base; disk finely but deeply

and distinctly punctate, the punctures generally separated by fully twice their

own widths but becoming gradually very dense, almost contiguous, although

not confluent, toward the sides. /ytra a little less than three times as long

as the prothorax and, behind the middle, quite distinctly wider, broadly ogival

at apex; sides distinctly arcuate; disk finely, rather sparsely and irregularly

punctate, with very imperfectly defined, distant, unimpressed series of slightly

larger punctures only toward the sides and especially near the base. Abdomen

finely, sparsely punctate, as usual much more coarsely and generally more

densely so near the sides. Legs moderate, the posterior tarsi very distinctly

shorter than the tibi#. Length 4.2-4.8 mm.; width 2.0-2.2 mm.

Nebraska—Cab. LeConte; Colorado.

The series of punctures on the elytra are less distinct than in any

other species of this group, and on the inner half are only traceable

under careful observation and with the exercise of a considerable

amount of imagination. The prothorax is slightly wider just be-

hind the middle than at base. |

EPITRAGUS Latr.

The species of Epitragus are, in general, strongly isolated among

themselves, in fact more conspicuously so than in any other Tene-

brionide genus which I can recall to mind at present; the trans-

verse prosternal groove is well developed in all the representatives

which I have seen. The following species is not closely related to

any other :—

E. fusiformis n. sp.—Elongate, fusiform, rather slender, moderately

convex, piceous-black with an eneous tinge, polished between the extremely

dense punctures. Head fully as long as wide, finely, deeply, very densely

punctate ; supra-orbital fold completely obsolete above the eye, feebly evident

for a short distance before it; antenne rather long, but strongly and gradually

clavate, the third joint long, tenth a little wider than long. Prothorax about

one-fifth wider than long, the apex three-fourths as wide as the base, trans-

versely truncate between the strongly advanced and acute apical angles; base

broadly, strongly lobed in the middle; basal angles right, not at all rounded,

sometimes feebly prominent; sides extremely feebly, nearly evenly arcuate ;

disk finely but deeply and very densely punctate, the punctures finer and in

close contact near the sides, distinctly separated toward the middle where there

is a narrow impunctate median line. lytra at base not distinctly wider than

the prothorax, rather less than three times as long as the latter and, near the

middle, two-fifths wider, finely, irregularly, evenly and extremely densely

punctate throughout, the punctures shallow, each bearing an excessively

minute robust acuminate seta which does not project much beyond the limit

of the puncture; apex acutely ogival. Abdomen finely, very densely punctate,

and with short fine inconspicuous pubescence. Length 10.5-11.2 mm.; width

4.7 mm.

Arizona.

The mesosternum is deeply and acutely excavated as usual. In

tomentosus, however, the mesosternum is not even distinctly im-

pressed and that species will therefore have to be placed in another

genus for which I would suggest the name Epitragodes.

lished by Mr. Champion; it belongs to the section having ‘the middle lobe of

the epistoma produced and rounded, and the pronotum similar in the sexes.

KE. gracilis n. sp.—Fusiform, slender and elongate, moderately, evenly

convex, bright wneous, polished; pubescence very short and coarse, sparse

and very inconspicuous. Head rather finely, deeply, not very densely punc-

tate, very sparsely so in the middle; supra-orbital fold obsolete above the eye,

but feeble and slightly arcuate before it; antenne long. Prothorax but slightly

more than one-fourth wider than long, the apex distinctly narrower than the

base, subtruncate between the very acute and greatly advanced and prominent

angles ; base strongly lobed in the middle, the basal angles acute and promi-

nent; sides very feebly arcuate, sinuate near the basal and apical angles ;

disk with an elongate-oval, foveolate impression just before the scutellum,

also impressed laterally along the basal margin, finely, very sparsely punc-

tate, the punctures extremely fine and rather feeble toward the middle, with-

out trace of an impunctate median line. Llytra at base but very slightly wider

than the prothorax, less than three times as long as the latter and, in the

middle, about one-third wider ; apex gradually very acute; humeri rounded ;

disk finely, irregularly punctured, the punctures rather dense laterally, sparser

and with indefinite distant series of very fine punctures toward the suture.

Mesosternum deeply excavated. Length 10.0 mm.; width 4.0-4.3 mm.

Mexico—State of Guerrero. Mr. Baron.

The elytra have very broadly and feebly impressed longitudinal sulci, which

are more pronounced toward the suture, the intervals there becoming very

feebly convex and equal to them in width; this structure is very similar to

that previously described in Kurymetopon discors and other allied species.

Coleopterological Notices. 367

prothorax being right, not rounded, not everted and not prominent,

but in the absence of a typical representative of the latter species I

am unable to describe it; the specimens were collected at El Paso,

Texas.

C. pallidum n. sp.—Moderately convex, pale Inteo-testaceous through-

out, rather shining, subglabrous, the widely scattered sete slightly evident

behind. Head finely, rather feebly but densely punctate; eyes large, supra-

orbital fold fine, short; antenne long and slender. Prothorax not more than

one-third wider than the head, two-fifths wider than long; apex about as wide

as the base, very feebly arcuate between the advanced, acute and prominent

angles ; base transverse, broadly bisinuate, the basal angles slightly acute and

prominent; sides strongly, subangularly arcuate at or just before the middle,

thence convergent and straight or broadly, extremely feebly sinuate to base

and apex; disk rather coarsely but variolately punctate, the punctures very

densely crowded laterally, very slightly separated toward the middle, with a

broad, subimpunctate and irregular median line. Elytra across the humeri

almost one-fourth wider than the pronotal disk, behind the middle from one-

third to one-half wider than the latter, nearly four times as long; disk rather

finely, subserially punctate; humeri rounded. Length 6.4-7.0 mm.; width

Texas (El Paso).

In addition to the characters given in the table, this species

differs from abnorme in its larger size, more robust form, paler

color and shorter, almost squarely truncate middle lobe of the

epistoma ; in abnorme the middle lobe is evenly, almost semi-circu-

larly rounded and is much longer. The series consists of five

specimens and does not indicate any notable variation either in

color or size.

ZOPHERUS Lap.

Z. imduratus n. sp.—Robust and convex, deep black throughout, the

pronotum dull and with a strong alutaceo-sericeous lustre; elytra more shin-

ing. Head moderate, sparsely, not very coarsely punctate; antenne very

short and robust. Prothorax fully as long as wide, widest and with the sides

very broadly subangulate at two-fifths the length from the apex, the latter

broadly emarginate, subtruncate between the advanced and narrowly rounded

angles; base equally wide, very feebly arcuate; sides convergent from anterior

two-fifths to the base and broadly obtusely subangulate at basal third; disk

convex, coarsely but sparsely punctate, the punctures strongly muricate.

Elytra about two-thirds longer than the prothorax and, in the middle, nearly

one-fourth wider, evenly oval, convex, feebly emarginate at base; disk strongly

but rather finely, densely and confusedly tuberculate, the two apical tuber-

cles very strong, the channels very deep but rather short. Abdomen coarsely,

sparsely, punctate. Length 16.5 mm.; width 7.0 mm.

368 Coleopterological Notices.

California (Julian). Mr. Dunn.

This species is somewhat allied to granicollis, na differs in its

shorter, less slender form relatively wider, more finely and densely

tuberculose elytra and very much finer and more asperate punctures

of the pronotum; the elytral tubercles are strongly shining.

In granicollis the elytra are but just perceptibly wider than the

prothorax and are much more elongate-oval. In cnduratus the

space separating the antennal cavities from the lateral thoracic

margin is scarcely two-thirds as wide as in granicollis, and the

transverse cavity of the fifth abdominal segment is bounded poste-

riorly by an evenly sinuous wall, while in granicollis the posterior

wall of the cavity is abruptly and strongly toothed in the middle ;

this is a very important difference, for on examining a series of

seven specimens of tristis, composed of males and females, I can-

not perceive the slightest variation in the form of this curious ex-

cavation sexual or otherwise; in dristis the posterior wall of the

cavity has a small rounded lobe in the middle, not by any means

as prominent and dentiform as in granicollis. Four specimens of

concolor show no variation in the form of the cavity which is nearly

as in granicollis; it is also very similar in opacus and gracilis.

The sculpture of the pronotum in induratus is very nearly as in

opacus, but the elytra are entirely different.

even parallel lines of closely placed suberect scales which are separated by

about one-third the width, the interval scarcely perceptibly impressed except

near the base and totally devoid of pubescence ; surface thence to the sides

with a few widely scattered and smaller scales. lytra oval, three-fourths

longer than wide, in the middle about twice as wide as the prothorax, the

cost very strong, each bearing a dense series of unusually long erect ex

spaced. Abdomen coarsely and densely punctate throughout. Legs moderate.

Arizona (Tugson). Mr. Wickham.

This species is not at all closely allied to any other, and may be

easily distinguished by its more robust form and very prominent

lateral and costal fimbriz ; also by the two even setose lines of the

pronotal disk.

A. Simplex n. sp.—Rather slender, very dark piceous-brown, alutaceous

in lustre. Head slightly longer than wide; sides behind the eyes just visibly

convergent for a short distance, then very gradually, broadly rounded to the

distinguish it.

ASIDA Latr.

A. angustula n. sp.—Slender, convex, dark castaneous throughout ;

sides subparallel; upper surface very sparsely covered with short, very fine,

erect hairs; legs densely clothed with short, stiffer and less erect hairs which

are more conspicuous on the tibiz and tarsi; anterior tibie with the exterior

angle acute and prominent. Head moderate, coarsely and rather densely

punctate ; antenne short but very slender, not longer than the prothorax, not

incrassate but with the tenth joint triangular and abruptly much wider than

the ninth, fully as long as wide, eleventh as usual very small. Prothorar

about two-fifths wider than long; sides parallel and rather strongly arcuate,

very feebly sinuate near the basal angles which are acute and slightly promi-

nent posteriorly, the base transversely truncate between them; apex broadly,

rather strongly emarginate in circular arc; disk widest at the middle, more

longitudinally convex in basal half thence declivous and transversely convex

in middle two-thirds to the apex, transversely feebly impressed near the base ;

sides rather feebly and not very widely reflexed throughout; surface rather

coarsely, deeply and densely punctate, the punctures rounded, perforate and

not at all muricate. lytra more than three times as long as the prothorax

and, in the middle, scarcely one-third wider ; sides parallel and feebly arcuate ;

humeri obtuse and not prominent; apex rather abruptly declivous ; lateral

margins fine but distinct, terminating abruptly near the apex; disk strongly,

evenly, transversely convex throughout, finely, very sparsely and irregularly

punctate, each puncture having immediately before it a fine but very strong,

perfectly erect, obtusely-pointed tubercle; discal coste completely wanting.

Legs short but slender, the pubescence pale ferruginous yellow and conspicu-

ous. Length 14.0-15.0 mm. ; width 6.0-6.5 mm.

hairs of the dorsal surface, and in its densely pubescent legs. The

four specimens before me do not indicate any variation.

CONIONTIS Esch.

A somewhat extensive genus, restricted in habitat to the true

Pacific coast fauna. In the latitude of Puget’s Sound the species

extend into the mountains of western Montana, where specimens

of ovalis have been taken in the Bitter Root valley. Proceeding

southward, the eastern limit of range seems to approach the coast,

the area becoming gradually narrower, and finally vanishing with

a few peculiar species in the neighborhood of San Diego. It has

been stated that one species extends its range to the eastern slopes

of the Rocky mountains, but this is doubtful, there having been in

all probability some confusion of localities. Beyond the southern

limit, as here defined, the genus is replaced by the closely allied

Celotaxis, which is confined in habitat as far as known to the

single small island of Guadalupe. The geological conditions exist-

ing long ago in the Tertiary, which have given rise to this isolated

group of species, will be further discussed under the head of Conz-

ontis lata.

There are several circumstances which render the identification of

the species a very difficult and uncertain task, even for the present

family, and among these should be mentioned the almost total

absence of any structural differences, also the marked persistence

and uniformity of type, and, at the same time, a considerable amount

of individual variation. It is almost absolutely essential therefore

to study large series of specimens, at least of several species, in

order that the peculiar laws of variation may be adequately appre-

ciated. The only noticeable structural variable, if such it can be

called, refers to the prosternal process, which is sometimes sur-

rounded by a fine convex bead and at other times simple, but I find

that this character is of but little value.

Each puncture of the elytra bears a seta, sometimes erect, but

generally recumbent, occasionally extremely short, not projecting

notably beyond the puncture, but sometimes much longer; after

careful study of extensive material, it seems probable to me that

this scanty vestiture may afford the best means of arbitrarily

grouping the species. It must be noted, however, that as these

sete are brittle and sometimes easily’ removable, care must be

taken in the case of old specimens, to examine them under sufficient

power to reveal their condition; if broken and consequently abnor-

mally short, which can be readily determined, it is very rare that

one or two occasional sete will not remain to indicate the nature

of the normal vestiture. When perfect the sete are finely pointed

and quite constant in size throughout the individuals of a species.

The Coniontini constitute a very isolated tribe, but as we are

compelled under the present classification to retain it in the Asid-

ine, on account of the presence of a distinct trochantin, it would

undoubtedly be more consistent to place it at the beginning of that

subfamily than at the end, because of the extent and obliquity of

the posterior coxe, in which it finds many parallels among the

Tentyriine, but stands absolutely alone in the Asidinee.’

374 Coleopterological Notices.

In the material before me there are some other doubtful forms

represented in each case by one or two specimens. Some of these

will quite probably prove to be valid species, but I have preferred

not to name them at present.

C. abdominalis Lec.—Proe. Ac. Phila., 1859, p. 77.—Robust, strongly

convex, parallel, but slightly more than twice as long as wide, shining. Heud

rather small and coarsely punctate; antenne black, rather robust. Prothorax

nearly two-thirds wider than long, generally widest at about the middle, the

sides thence parallel and nearly straight to the base, broadly rounded ante-

riorly ; base transverse, the angles very feebly produced posteriorly; disk

very finely and sparsely punctate, a little more coarsely and densely so later-

ally, the lateral edges narrowly but strongly reflexed. lytra from one-third

to two-fifths longer than wide, rather coarsely deeply and sparsely punctate,

and distinctly rugulose, especially toward the apex. Abdomen coarsely but not

very densely punctate, more or less rugulose. Length 14.0-17.0 mm.; width

7.0-8.3 mm.

California (Monterey ; Santa Barbara; Los Angeles).

The edges of the elytra, when viewed laterally, are generally very

feebly arcuate, sometimes nearly straight. The punctuation of the

upper surface is rather constant, but the sculpture of the abdomen

varies considerably, a specimen from Santa Barbara before me

having the surface smooth, polished, almost devoid of rugulosity,

and finely and very sparsely punctate. The elytra are a little more

than twice as long as the prothorax in the female, relatively shorter

in the male.

C. owalis Lec.—Ann. Lyc. N. Y., V, p. 131.—Oblong-oval, strongly con-

vex and shining; sides nearly straight in the middle. Head very nearly one-

half as wide as the base of the prothorax, rather coarsely and densely punctate ;

antenne blackish, pale at apex, moderate. Prothorax rather short, from three-

fourths wider than, to nearly twice as wide as long; sides feebly arcuate,

generally convergent from base to apex, very feebly so and sometimes nearly

parallel in basal half; base truncate, very feebly sinuate near the angles

which are slightly produced posteriorly; disk sparsely but rather strongly

punctate toward the middle, densely and very coarsely so laterally, the sides

not narrowly reflexed but strongly finely beaded. lytra always distinctly

more than twice as long as the prothorax, sometimes feebly inflated behind

the middle, unevenly, very coarsely and deeply punctate, the punctures often

irregularly coalescent, especially toward apex. Abdomen finely, rather sparsely

punctate, the punctures subtransverse, very feebly asperate, especially toward

the sides. Length 10.0-11.5 mm.; width 5.2-5.7 mm.

Coleopterological Notices. tit

Although allied to abdominalis this species is very much smaller,

and is exclusively northern in habitat. In both, the elytra are

strongly rugulose toward apex, but this uneven effect is produced

by actual inequality of the surface, the punctures being smaller

and scattered over the surface of the wrinkles in abdominalis,

while in ovalis it is the result of actual coalescence of the larger,

deeper and more broadly impressed punctures. The elytral punc-

tures are distinctly smaller in the Montana specimens.

C. inzequalis n. sp.—Rather elongate, strongly convex, with the sides

parallel and nearly straight, the apex of the elytra very unusually prolonged

and acutely rounded; surface strongly shining. Head distinctly less than

one-half as wide as the base of the prothorax, rather sparsely and finely

punctate, more coarsely so anteriorly ; antenne piceous-black almost through-

out, rather robust but scarcely at all incrassate toward tip. Prothorar about

three-fourths wider than long; sides almost parallel and feebly arcuate in

basal two-thirds, rounded anteriorly ; base truncate, very feebly sinuate later-

ally, the angles slightly produced and narrowly rounded ; disk very minutely

and extremely sparsely punctate throughout, the punctures but slightly more

evident toward the sides which are very narrowly but strongly reflexed.

Elytra distinctly more than twice as long as the prothorax, sparsely but very

deeply and coarsely punctate, the punctures very widely impressed, producing

a very unevenly rugulose appearance toward apex where they are imperfectly

coalescent in twos or threes. Abdomen polished, excessively minutely feebly

and sparsely punctate. Length 13.5 mm.; width 6.2 mm.

California (exact locality unknown).

Although represented by a single specimen, there can be no

reasonable doubt that this species is comparatively isolated. In

general habitus it resembles eschscholtzt, but can at once be dis-

tinguished by its very sparse punctuation and radically different

elytral sete, as well as its polished and exceedingly minutely punc-

tate pronotum,

C. robusta Horn.—Trans. Am. Phil. Soc., XIV, p. 296.—Robust, strongly

convex, about twice as long as wide; pronotum finely alutaceous ; elytra more

strongly shining and more piceous-brown in color. Head rather small, less

than one-half as wide as the prothorax, finely punctate; antenne very robust,

slightly incrassate toward apex; eleventh joint as usual much narrower.

Prothorax about two-thirds wider than long; the sides parallel and almost

straight in basal two-thirds, strongly rounded and convergent anteriorly ;

base transverse, rather strongly sinuate laterally, the angles being very dis-

tinetly produced posteriorly and scarcely at all rounded; disk sparsely and

very minutely punctate throughout; side margins narrowly but strongly re-

flexed. lytra scarcely more than twice as long as the prothorax, very decliv-

ous behind, the apex rather acutely rounded ; surface rugulose throughout,

especially toward apex, and with three imperfectly defined and very feeble

eroded grooves ; punctures very minute and sparse throughout. Abdomen finely

and sparsely punctate, with slight traces of rugulosity. Length 14.0 mm. ;

width 7.0 mm.

California (Santa Barbara Co.).

The original description of this species was drawn from a series

comprising several distinct forms. The specimen designated by Dr.

Horn as “1,” judging from the coarseness of the dorsal punctua-

tion, is probably a specimen of abdominalis in which the ventral

punctuation and rugulosity has become rudimentary. The descrip-

tion here given is taken from a specimen in the cabinet of LeConte,

and is distinguished from abdominalis by its very fine punctuation

of the upper surface. From elliptica which has also been confounded

with robusta, the latter is at once distinguishable not only by its

rugulose, but at the same time more convex elytra, with strongly

arcuate lateral edges.

C. elliptica Casey.—Cont. Col. N. A., I, p. 46.—Robust in the female,

the male very slightly more than twice as long as wide, moderately convex,

smooth, strongly shining, the pronotum feebly alutaceous, intense black

throughout. Head small, very distinctly less than one-half as wide as the

prothorax, very finely and somewhat densely punctate; antenne slender, the

outer joints scarcely perceptibly incrassate. Prothoraxr from two-thirds to

nearly four-fifths wider than long; sides subparallel or very feebly conver-

gent from the base to slightly beyond the middle, broadly rounded anteriorly ;

base transverse, thé angles feebly prolonged posteriorly ; disk excessively

finely, very sparsely punctate, the punctures but slightly closer and stronger

toward the sides, the lateral edges extremely narrowly and finely reflexed.

Elytra always much more than twice as long as the prothorax, generally slightly

inflated behind the middle, gradually and rather feebly declivous behind ;

apex acutely rounded; disk nearly smooth, very minutely and sparsely punc-

tate. Abdomen smooth, polished, extremely minutely and sparsely punctate.

Length 12.5-14.5 mm. ; width 6.0-7.4 mm.

California (Kern and San Diego Cos.).

Most of the specimens have the elytra smooth, but in several

there is a distinct indication of the three eroded’ grooves noted

under robusta, and the same is the case in ovalis and abdominalis,

the erosions constituting a feature which may at some time have

characterized a considerable part of the genus. The variation in

form is very remarkable, one female having the prothorax distinctly

inflated before the middle ; the nine representatives agree rigorously,

however, in the nature of the line forming the edges of the elytra,

which is invariably straight from a lateral point of view.

C. lata Lec.—New Species Col., 1866, p. 113.—Broadly oval, moderately

convex, smooth, subalutaceous. Head small, rather coarsely and sparsely

punctate; antenne rather slender, but distinctly incrassate toward apex, the

tenth joint slightly longer than wide. Prothorax strongly transverse, nearly

twice as wide as long, very strongly narrowed from base to apex, the latter

not quite one-half as wide as the base which is very strongly bisinuate, the

angles acute, not at all rounded and not projecting posteriorly beyond the

median lobe ; sides strongly, evenly arcuate ; disk densely and rather strongly

punctured; side margins not reflexed although very finely and acutely beaded.

Scutellum very small. Elytra scarcely one-third longer than wide, two and

' one-half times as long as the prothorax, the surface smooth, rather dull and

just visibly undulated toward apex, somewhat densely and very finely punc-

tate, the punctures not quite as large as those of the prothorax. Abdomen

shining, sparsely, finely punctate, the punctures denser and rather asperate

toward the sides. Length 10.8-11.7 mm.; width 5.3-5.7 mm.

California (Island of San Clemente).

This species represents a very peculiar type, completely isolated

from any of those at present known as inhabiting the neighboring

continent, and peculiar to the Santa Barbara group of islands. It

is immediately distinguishable by its broad evenly oval form, pecu-

liar punctuation and strongly bisinuate base of the prothorax.

Var. insularis.—Similar to /ata but much narrower, more shining, the head

relatively larger and more finely punctate, the prothorax only one-half wider

than long, the apex fully one-half as wide as the base, the sides less strongly

arcuate. Length 10.0-11.5 mm.; width 4.7-5.1 mm.

California (Island of Santa Cruz).

While conforming to the peculiar typical facies of lata, the speci-

mens from Santa Cruz differ to such an extent as to require special

designation at least as a variety.

Before discussing the geological changes which the existence of

these two northern forms and the genus Celotaxis apparently reveal

to us, it would perhaps be well to note the tendency of the species

of Coniontis, inhabiting the southern limit of the region near San

Diego, to become conspicuously pubescent, as seen in subpubescens

and the still more aberrant and local form described below as par-

viceps, the latter being probably a degenerative type.

It is well known that a large percentage of all the productions

of the islands lying off the coast of California, although having an

essentially Californian character, are specifically distinct and strictly

378 Coleopterological Notices.

peculiar to them; and it is also a fact that the proportion of endemie

species and the relative divergence of type become more pronounced

as we proceed southward, until in Guadalupe the endemicity becomes

one of the most remarkable of the faunal characteristics.

A correlation of these facts seems to indicate that the islands off

the coast at one time formed a continuous peninsula, trending

almost directly north and south, joining the continent by a broad

base between Pt. Concepcion and Cape Vincente,’ and tapering to

a point at Guadalupe. The fact that the submarine contours exhibit

a series of salients in the 500, 1000, 1500 and 2000 fathom curves,

extending in the general direction of Guadalupe, gives greater

probability to this assumption.

At that time, which was probably at least as early as the begin-

ning of the Pliocene, there was a free intermingling of the conti-

nental species characterizing this epoch. Shortly thereafter the

peninsula began to subside, interrupting this communieation, and,

as the islands were successively separated, the quota of individuals

remaining upon them gradually diverged under the isolated and

special environmental conditions by which they became surrounded ;

or, in short, have become specifically distinct.

Guadalupe being the first land detached should display the most

marked divergence in its productions, although by this hypothesis

the essential features should remain as purely Californian as those

of the other islands,—facts which have long been well known. It

may be objected, however, that as the salient of the 2000-fathom

continental contour is separated from the corresponding contour of

? Out of 296 species of plants collected by the eminent Californian botanist

Mr. E. L. Greene, on the Island of Santa Cruz, 48 are peculiar to the Santa

Barbara group, and 28 are peculiar to Santa Cruz alone. In Guadalupe out

of 145 known species of plants, 24 are strictly endemic. Except the birds,

plants, however, form perhaps the least reliable criterion for the estimation of

relative endemicity, as the strongly vitalized and often comparatively inde-

structible seeds are so apt to be successfully introduced by currents, winds

and migratory birds. The real faunistic isolation of these islands will be >

much more clearly demonstrated by the wingless epigeal species of Coleoptera,

and of these there is not a single species at present known from Guadalupe

which is not strictly peculiar to the island.

2 To one passing along the coast of Santa Barbara Co. and viewing the very

bold and precipitous slopes of the Santa Inez Mountains, the desire to liken

them—in connection with the present subsidence theory,—to the escarpment

of a great fault, is almost irresistible.

Coleopterological Notices. 379

the island by an appreciable interval, the island being thus isolated,

rising rapidly like a stupendous peak from a great depth, we should

have to assume an enormous subsidence, but of course this alone

would not invalidate the theory. It may be possible also that as

the intermediate region subsided, there was a gradual and counter

elevation of the land seaward forming the apex of the peninsula.

The subsidence of the peninsula probably continued through the

Pliocene, but it was not until the early Quaternary that the islands

near the coast became isolated.’ It is only natural to assume, there-

fore, that which we know to be true, that the fauna of these islands

should be less modified than that of Guadalupe, although remaining

closely allied to it. The ancestral type of Coniontis lata has, in

Guadalupe, become the densely pubescent genus Celotaxis, while

upon the mainland it seems to have totally disappeared, there being

no species at present known which at all resembles C. lata or its

variety insularis.

A thorough exploration of these islands by a scientific entomo-

logist would be fruitful in many interesting results bearing upon

their geological history, especially would’ this be the case with the

epigeal species which are not readily transportable by winds and

ocean currents. This is perhaps the greatest desideratum in our

knowledge of the nearctic fauna.

C. opaca Horn.—Trans. Am. Phil. Soc., XIV, p. 296.—Oblong-oval,

surface almost smooth, dull and finely alutaceous. Head finely, somewhat

densely punctate; antenne somewhat slender. Prothorax rather short, nearly

three-fourths wider than long, the apex fully two-thirds as wide as the base,

the latter almost transverse, broadly, feebly sinuate laterally, the angles sub-

acute and scarcely projecting posteriorly beyond the median lobe; sides broadly

rounded anteriorly, parallel and nearly straight in basal half; disk finely but

deeply, distinctly and very densely punctured toward the sides, very minutely

and more sparsely so toward the middle; lateral margin not reflexed, finely

beaded. Llytra very distinctly more than twice as long as the prothorax,

rectly identified. It is easily recognizable by its rather small size,

smooth and strongly alutaceous lustre, extremely dense punctua-

which bears an exceedingly minute seta not projecting beyond the

limits of the puncture.

Cc. punctipes n. sp.—Oblong, moderately convex, feebly shining, smooth

or very nearly so. Head rather broad, fully one-half as wide as the prothorax,

short, about two-thirds wider than long, the apex fully three-fourths as wide

as the base, the latter transversely truncate, very feebly sinuate near the

basal angles which are not at all rounded, and which project posteriorly

distinctly beyond the median portion; sides evenly, rather strongly arcuate

throughout, the widest part of the disk being near the middle; disk very finely

and sparsely punctate toward the middle, the punctures becoming rapidly

California (San Bernardino Co.).

A rather remarkable species, readily distinguishable from any

other by the extremely coarse punctuation of the lateral portions of

the pronotal disk and of the femora. In the type, the base of the

prothorax is narrower than the middle portions, but this is in all

probability an abnormal variation.

C. elongata n. sp.—Oblong-elongate with the sides straight and parallel,

moderately convex, strongly polished, the pronotum very faintly subalutace-

tures becoming denser and much coarser on the epistoma; antennz moderate.

Prothorax elongate and strongly developed, from less than one-third to two-

fifths wider than long, the apex about two-thirds as wide as the base, the

latter transverse, very broadly, feebly sinuate laterally, the angles subacute

but not distinctly more prominent than the median parts ; sides broadly arcu-

ate anteriorly, nearly parallel in basal two-thirds ; disk extremely minutely,

sparsely punctured toward the middle, the punctures becoming rapidly rather

coarse, deep and distinct, but still somewhat sparse, near the sides; lateral

edges finely but strongly beaded. L/ytra about twice as long as the prothorax,

sparsely, finely punctate, the punctures distinct, and generally rather larger

California (San Francisco).

In the large series of seventeen specimens before me, there is

none which can be positively asserted to have been taken in any

other locality than that indicated; it appears to be a species peculiar

to the sandy coast region, perhaps extending down to Monterey

or Santa Barbara. Viatica is very readily known by its slender

parallel forin and very minute punctuation; from elongata it may

be separated at once by its much shorter prothorax and very much

more pronounced longitudinal convexity.

California (San Francisco).

This species also appears to be confined to the coast regions about

San Francisco, where it is very abundant. In its normal state, the

sete growing from the elytral punctures are always long and dis-

tinct, and the original type of affinis does not differ in the slightest

character from the species described by Mannerheim as inhabiting

the immediate locality alluded to. The sete are, however, liable to

be broken off or rubbed out of the punctures, which will account for

several errors in the books.

California (San Francisco).

A very small species, confined to the same regions as viatica and

eschscholtzi and also very abundant. Its resemblance to the latter

of these species is so marked, that mistakes are very liable to occur

in identifying the extremes of each; with large series, however, it

is readily seen to differ by certain constant characters, among which

may be mentioned the smaller, more coarsely punctured head, very

slightly shorter prothorax, and distinctly more finely and sparsely

punctured elytra, the sete of both the elytra and abdomen being a

little longer, more evident and more persistent; it is also constantly

much smaller in size and slightly less convex. It varies remarkably

in size.

Cc. puncticollis Lec.—Ann. Lyc. N. Y., V, p. 131.—Slender, parallel,

very convex and subcylindrical, pointed behind, subalutaceous, smooth. Head

moderate in size, rather finely, densely punctate; antenne rather short, very

robust, the tenth joint distinctly transverse. Prothorax from one-half to two-

thirds wider than long, the apex two-thirds as wide as the base, the latter

almost transversely truncate, the basal angles but very slightly prominent

posteriorly; disk very finely and extremely densely punctate laterally, rather

abruptly much more sparsely so along the middle; lateral margins very

minutely and acutely beaded. lytra distinctly more than twice as long as

the prothorax, very minutely, feebly punctate, generally with several extremely

feeble and rudimentary longitudinal cost, which are more visible toward the

suture and rather narrowly separated, the crests of the costz almost impunc-

tate, the intervals rather densely and confusedly so. Abdomen strongly con-

vex, sparsely and extremely minutely punctate. Legs very short, slender,

generally more or less rufescent. Length 7.6-10.0 mm.; width 3.3-4.2 mm.

California (San Francisco, Benicia).

This very peculiar species is one of the smallest of the genus.

The elytral coste are generally almost completely obsolete, but

even when entirely invisible the punctures are left distributed in

very imperfectly defined longitudinal streaks or patches. The bairs

growing upon the elytra are rather short, but extend far beyond the

limits of the exceedingly small and feeble punctures. It is rather

abundant, and appears to be limited to the same region as viatica.

C. alutacea n. sp.—Oval, strongly convex, dull throughout. Head

somewhat finely, moderately densely punctate; antenne robust. Prothorar

fully three-fourths wider than long, the apex strongly sinuate and about

three-fifths as wide as the base, the latter transverse and broadly, feebly bi-

sinuate, the basal angles acute and projecting posteriorly but slightly beyond

the broadly arcuate median lobe; sides rather strongly arcuate anteriorly,

generally a little straighter toward base; disk rather sparsely, very finely

punctate toward the middle, the punctures becoming gradually much larger

deep, very distinct and moderately dense laterally ; side margins finely but

strongly beaded, the bead bordered internally by a coarse deep groove. Llytra

fully two and one-half times as long as the prothorax, rather abruptly and

acutely pointed behind, densely punctate, the punctures rather large and

distinct, very confusedly coalescent toward apex producing a densely rugu-

lose appearance, which becomes much less pronounced anteriorly. Abdomen

polished, very finely, sparsely punctate. Zegsslender. Length 9.0-11.0 mm. ;

Cc. subpubescens Lec.—Ann. Lyc. N. Y., V, p. 131.—Oblong-elongate,

parallel, somewhat depressed, feebly shining throughout. Head moderate in

size, very coarsely, deeply and not very densely punctured; antenne long

and slender, distinctly incrassate near the apex. Prothorax about two-thirds

wider than long, the apex moderately sinuate, nearly two-thirds as wide as

the base, the latter broadly truncate and straight, the basal angles abruptly

produced and distinctly prominent posteriorly, acute; sides arcuate, straighter

toward base; disk finely but distinctly, moderately densely punctate, the

punctures sparse and rather finer toward the middle; lateral margins strongly

but finely beaded and finely grooved within the bead. £lytra distinctly more

than twice as long as the prothorax, broadly, feebly and unevenly undulated,

the undulations becoming strong coarse rugulosities toward apex ; punctures

fine, not very dense, each with a very long fine recumbent hair. Abdomen

polished, smooth, sparsely, very finely punetured. Legs well developed, very

slender. Length 9.2-10.8 mm.; width 4.24.8 mm.

California (Marin, Santa Clara and San Diego Cos.).

This species, although assigned here to another section of the

genus because of its conspicuous pubescence, is in reality very

closely allied to abdominalis and robusta, and in the original type

the three eroded grooves on the elytra, characterizing that group

of species, are clearly but of course very faintly visible; another

character allying it to abdominalis is the nature of the elytral

rugulosity, which is not caused by the coalescence of deep coarse

punctures; in subpubescens the punctures toward apex are fine and

distributed over the surface of the convexities. It is distributed

throughout the maritime districts of California but appears to be

rather rare.

C. montana n. sp.—Oblong-elongate, rather feebly convex, sometimes

distinctly flattened above, rather feebly declivous behind and gradually,

acutely pointed ; surface strongly alutaceous throughout; elytra frequently

conical. Head sparsely but coarsely punctate, the punctures finer posteriorly ;

antenne moderate. Prothorax well developed, from three-fifths to three-fourths

wider than long, almost as in subpubescens but with the pubescence shorter ;

punctures excessively fine toward the middle. £lytra fully two and one-half

times as long as the prothorax, feebly undulated, subrngulose toward apex,

the punctures throughout rather sparse and extremely fine, each having a

long somewhat coarse subrecumbent fulvous hair. Abdomen very feebly sub-

alutaceous, finely, sparsely punctate. Legs moderate. Length 10.8-13.0 mm. ;

width 5.0-6.3 mm.

Coleopterological Notices. 385

California (Lake Tahoe—elevation 6300 feet).

A good series of eight specimens shows that montana, although

allied to subpubescens, is abundantly distinct; it differs in its much

larger size, shorter, sparser and less conspicuous pubescence, and in

the nature of the elytral punctuation which distinguishes it at once

from that species. The punctures are generally distinct and deeply

impressed, but toward apex they gradually become smaller, and

finally extremely fine and feeble, and,—although in reality sepa-

rated by about the same interval between centres—apparently much

sparser. The majority of specimens display very distinct traces of

the three eroded grooves.

C. pallidicornis n. sp.—Oblong-elongate, parallel, moderately convex,

smooth, strongly alutaceous throughout. Head somewhat coarsely but not

_ very densely punctate anteriorly ; antenne very slender, eighth joint much

longer than wide, tenth not quite as wide as long. Prothorax moderately

narrowed from base to apex, from one-half to three-fifths wider than long, the

sides moderately and almost evenly arcuate ; base transverse, feebly sinuate at

the sides, the basal angles being right, very narrowly rounded and but very

slightly prominent posteriorly ; disk very minutely, sparsely punctate toward

the middle, the punctures gradually coarser and quite distinct, but not very

dense, laterally ; marginal bead very fine. /ytra distinctly more than twice

as long as the prothorax, almost smooth but very dull, with feeble traces of

rugulosity, somewhat sparsely and very finely punctate, the punctures becom-

ing finer toward apex, each bearing a stiff subrecumbent fulvous seta which is

rather short and inconspicuous, although projecting far beyond the limits of

the puncture. Abdomen sparsely, very minutely punctured. Length 8.2-9.0

mm.; width 3.84.1 mm.

Southern California.

Allied to montana in the gradual decrease in size of the punctures

toward the apex of the elytra, but quite distinct in its smaller size,

smoother surface and very much shorter and less conspicuous pubes-

cence. It is much more elongate and less convex than opaca, and

has the punctures toward the sides of the pronotum coarser and

very much sparser. The antenne and tarsi are testaceous through-

out, the legs piceous.

C. genitiva n. sp.—Oblong-elongate, parallel, with the sides straight,

rather strongly convex, the elytra rather shining, the pronotum strongly

alutaceous. Head well developed, coarsely deeply and rather densely punc-

tate anteriorly, much more finely and sparsely so posteriorly ; antenne rather

long and very slender, the third joint much more than twice as long as the

second, the tenth much longer than wide and but slightly wider than the

than long; apex about two-thirds as wide as the base, the latter transverse,

nearly straight in basal three-fifths; disk very finely, sparsely punctate, the

punctures becoming more distinct but still fine and rather sparse toward the

sides; lateral margins coarsely beaded. £lytra but very. slightly more than

twice as long as the prothorax, not very strongly declivous and rather acutely

rounded behind, very feebly subrugulose especially toward apex, the punc-

tures sparse but rather large, deeply impressed and very distinct, each bearing

a very fine elongate recumbent seta, the vestiture not at all conspicuous.

Abdomen sparsely but unusually coarsely and distinctly punctured. Femora

coarsely but sparsely punctate. Length 13.0 mm.; width 5.4 mm.

California (Lake Co.) Mr. Fuchs.

This species in general form can be compared only with elongata,

but is distinguished from it not only by its longer elytral sete, but

by its distinctly different antennal structure, the third joint in elon-

gata being less than twice as long as the second, and the tenth joint

a little wider than long. In the type the two inner of the three

eroded grooves are just traceable.

C. parallela nu. sp.—Oblong-elongate, parallel, with the sides straight,

rather depressed, the elytra slightly shining, the pronotum very strongly

alutaceous. Head rather densely, somewhat finely punctate, the antenne

moderate. Prothorar rather long and well developed, scarcely one-half wider

than long, the apex nearly three-fourths as wide as the base, the latter

broadly, rather strongly bisinuate, the median lobe broadly arcuate, the

basal angles acute and not rounded but not projecting posteriorly beyond the

median lobe; sides moderately arcuate anteriorly, nearly parallel and straight

in basal two-thirds; disk coarsely, very conspicuously and moderately densely

punctured, more sparsely and finely but still very distinctly so toward the

middle; marginal bead rather fine. /ytr@ about twice as long as the pro-

thorax, feebly rugulose, quite distinctly so toward apex, rather strongly,

C. parviceps nu. sp.—Elongate oval, moderately convex, rather dull and

alutaceous throughout; elytra feebly undulato-rugulose, especially toward

apex. Head small, coarsely, deeply, moderately densely punctate; antennz

moderate, third joint scarcely more than one-half longer than the second,

tenth triangular, as wide as long. Prothorax one-half wider than long, strongly

narrowed from base to apex, the latter scarcely more than one-half as wide as

the former ; apex very deeply sinuate; base very broadly emarginate through-

out the width, the basal angles being acute and posteriorly prominent; sides

evenly and rather strongly arcuate; disk rather sparsely punctate, the punc-

tures distinct toward the middle, rather denser and decidedly coarse laterally ;

side margius extremely minutely,-acutely beaded. Llytra but slightly more

than twice as long as the prothorax, extremely finely, not very densely punc-

tate, the punctures much finer than those near the sides of the pronotum

and becoming, toward apex, excessively minute and feeble. Abdomen rather

strongly convex, very finely, sparsely punctate, each puncture bearing a long

hair. Length 7.0-8.0 mm.; width 3.4-4.0 mm.

California (San Diego).

The punctures of the pronotum and elytra bear each a long rather

coarse fulyous seta, the vestiture being closely recumbent and very

conspicuous. This is a small and comparatively isolated species.

C. setosus n. sp.—Oval, strongly convex, rather shining, the pronotum

slightly alntaceous; elytra extremely feebly undulato-rugulose toward apex.

Head well developed, finely and sparsely punctured ; antenne long and some-

what robust, third joint twice as long as the second, tenth nearly as wide as

long, strongly obtrapezoidal. Prothorax two-thirds wider than long, the apex

two-thirds as wide as the base, the latter broadly, very feebly arcuate, broadly

distinctly sinuate laterally, the basal angles right, not rounded and projecting

posteriorly slightly beyond the median portions; sides almost evenly and

rather feebly arcuate; disk sparsely and extremely finely punctate toward

the middle, the punctures becoming much denser, rather strong and distinct

laterally, the sete very short and inconspicuous; side margins finely and

acutely beaded. E/ytra fully two and one-half times as long as the prothorax,

evenly and unusually obtusely rounded behind, densely and rather strongly

punctate, the punctures much larger than any of those of the pronotum, and,

toward apex, becoming rather fine and more feeble, each with a moderately

long, robust, erect and fulvous seta, the vestiture dense but not conspicuous.

Abdomen finely, sparsely punctate. Length 10.0 mm.; width 5.0 mm.

form, and peculiarities of the elytral pubescence. It is probably

one of the derivatives of the ancient type of ovalis, which inhabits

nearly the same region. The unique type exhibits decided traces

of a number of feeble approximate elytral ridges similar to those

of puncticollis. The elytra become strongly alutaceous and rather

coarsely creased toward apex, and the very feeble undulating in-

equality of the surface, which could scarcely be called rugulosity, is

not caused by partial coalescence of the punctures. In ovalis the

elytra are polished throughout, very coarsely, deeply punctate, the

punctures not becoming finer toward apex, where they are con-

fusedly coalescent causing a strongly marked rugulosity.

CONIONTELLUWS pn. gen. (Coniontini).

The species described by LeConte as Coniontis obesa, differs

structurally from the normal members of that genus in having the

eyes completely divided. If this were the only difference which

could be perceived, we might perhaps be warranted in considering

obesus and its allies as a mere section of Coniontis, but as this struc-

tural peculiarity is supplemented by several other characters, I have

deemed it more proper to separate the species mentioned under

another name.

Coniontellus differs from Coniontis in having the eyes completely

divided, the antenne shorter, more slender, with a much greater

development of the second joint and a wider eleventh joint, and in

the form of the anterior tibiz, these being broader, shorter, more

strongly compressed and triangular. —

The genus is peculiar to the high arid mountainous table lands

and valleys of the Rocky Mountain system, and does not extend

westward beyond the Sierras. The species are all small and are

apparently much less numerous than those of Coniontis, those

which are known to me may be distinguished as follows :—

Sete of the elytra longer erect and distinct ; pronotal punctures very coarse,

with but little tendency to longitudinal coalescence.

Elytral sete long and conspicuous, coarse and fulvous, nearly as long as the

third joint of the posterior tarsus; body more robust, the elytra always

rather strongly inflated behind ; scutellum very small...........imnflatus

Elytral sete shorter, finer and sparser, not more than one-half as long as

C. inflatus n. sp.—Robust, strongly convex and shining, the elytra

infiated. Head rather less than one-half as wide as the prothorax, not very

coarsely but densely punctate, the punctures usually sparser toward the

middle; epistoma extremely densely punctured. Prothorax about twice as

wide as long, the apex nearly three-fourths as wide as the base, the latter

broadly truncate, the angles narrowly and abruptly produced posteriorly, very

acute; sides feebly arcuate, more strongly so near the apex; disk moderately

densely, very coarsely and deeply punctate laterally, more sparsely and much

more finely so near the middle; side margins very finely, acutely beaded.

Elytra about three times as long as the prothorax, and, at posterior third,

distinctly wider, rather coarsely but not densely punctate, the punctures

becoming much smaller toward apex. Abdomen sparsely but rather strongly

punctate. Length 6.5-7.4 mm. ; width 3.4-3.9 mm.

Nevada (Reno).

Differs considerably from either obesus or subglaber in its much

more robust form, inflated and relatively longer elytra, and the

much more conspicuous sete toward the apex of the latter. The

scutellum in the three specimens before me is much smaller and more

acute than in obesus, and very slightly smaller than in subglaber.

C. obesus Lec.—Coniontis ob.: Aun. Lyc. N. Y., V, p. 131 nota.—Robust,

subparallel, convex, rather strongly shining. Head well developed, finely,

rather densely punctate, more sparsely so near the middle. Prothorax fully

four-fifths wider than long, the apex three-fourths as wide as the base, the

latter transversely truncate, the angles very narrowly, abruptly and moder-

ately produced posteriorly, very acute; sides feebly arcuate; disk rather

densely and decidedly coarsely punctate, less coarsely and more sparsely so

toward the middle; side-margin very fine and acute, extremely narrowly

reflexed. lytra nearly two and one-half times as long as the prothorax,

abruptly narrowed in apical third which is angulate and acutely rounded at

apex; disk rather coarsely, deeply and moderately densely punctate, the

punctures a little more sparse and feeble toward apex. Abdomen sparsely,

rather finely but very distinctly punctured, the puuctures rounded. Length

Colorado (Long’s Peak). Cab. LeConte.

The description refers to the original type which is unique. The

elytral sete toward apex, when viewed along a line tangent to the

surface, are seen to be rather fine, erect, not dense and about one-

half as long as the third joint of the posterior tarsus. The lateral

pronotal punctures are coarse, very slightly longer than wide, and

not at all coalescent.

tudinally, finer, much sparser and more rounded near the middle ; side-margin

very fine and acute, not distinctly reflexed. Flytra nearly as in obesus but

more finely punctate, each puncture bearing a very minute seta. Abdomen

finely and sparsely punctate. Length 5.8-6.8 mm.; width 2.9-3.4 mm.

Montana (Helena). Mr. Wickham.

The elytral sete in this species are exceedingly minute, robust

and pointed, subrecumbent, and do not project much beyond the

external edge of the puncture. It resembles obesus very much, but

may be distinguished not only by the character of the vestiture, but

by the different punctuation. —

TENEBRIONIN.

The fundamental characters upon which the various tribes of this

great subfamily are at present based, seem to be unsatisfactory to

a considerable degree, and yet the difficulties involved in striving to

present a series of genera in linear form, which can no more lend

themselves to such treatment than the stars disseminated through

the firmament, is of course insurmountable. If, however, our

own genera are difficult of taxonomical arrangement, the European

genera are still more so, and are in a condition of decidedly unstable

equilibrium.

It is evident that one source of confusion may be the tenacious

retention, as a tribal character, of the sexual modification of the

anterior tarsus. Our own genera of Blapstini prove conclusively

that this is of no value whatever, either in the separation of tribes

or of genera, as it is subject to complete extinction even in Blap-

stinus itself, as will be shown under that genus. - Relegating this

very alluring but misleading character to the background therefore,

I believe it is possible, by giving greater prominence to other well

known but insufficiently appreciated characters, to bring about a

more harmonious grouping of the genera.

In examining the table on page 372 of the recent classification of

LeConte and Horn, which is essentially a repetition of that given

by LeConte in the first edition, we discover several inconsistencies,

as follows :—

1 The character relating to the dilatation of the head, in separat-

ing tribes V and VI from I-IV, is evidently of no importance, as

in tribe V the head in Opatrinus is not as prominent at the sides as

in Argoporis, and many other exceptions might be cited.

Coleopterological Notices. 391

2 It is difficult to draw any rigid distinction between the form of

tarsal vestiture of the Amphidorini and Upes, and,

3 It does not seem proper to class together genera like Tenebrio,

with the tarsi very sparsely and coarsely spinose beneath; and the

Upes, in which they are densely and finely pubescent.

After a prolonged and careful study of the genera involved, I

have been foreed to the conclusion that a purely natural tribal

classification, which shall include no exceptional cases, is a practical

impossibility, but, at the same time, the following arrangement of

the first few tribes of the subfamily seems, at least with the mate-

rial at hand, to be less objectionable in this respect than any which

I have been able to consult. The few known exceptions will be

noted below :—

Posterior coxe transverse, other characters as stated (Class. Col. N. A. p. 372).

The only exceptions which it is possible to cite at present, are the

genera Dendarus' and Colpotus of’the Eulabini, which have the

392 Coleopterological Notices.

tarsi densely clothed beneath with long flavate pubescence, and

Heterophilus of the Opatrumini,! which does not have the head

prominent at the sides. The remaining characters in these genera

are thoroughly those of the tribes in which they are placed.

In this scheme the Upini comprise the Upes and also the Euro-

pean Menephilus.

The Blaptini remain as at present organized.

The Pimeliini constitute a very homogeneous and interesting

tribe, composed of the European genera at present assigned to it.

The epipleure are extremely narrow throughout the length of the

elytra, but seem to be invariably entire. The fourth joint of the

maxillary palpi is unusually small. Sepidium does not belong any-

where near the Pimeliini, where it is placed in the European cata-

logues, but is a member of the Asidine.

The Scaurini will include Scaurus, Cephalostenus,? Cerenopus

and Argoporis, rendering necessary the formation of three distinct

groups or subtribes. Akis is in no way related to Scaurus, but

belongs to the Asidine, as is also the case with Morica and Cypho-

genia.

The Eulabini will include Eulabis, Dendarus, Colpotus, Helio-

pates, Phylax—the resemblance of this genus to Hulabis is quite

marked—Sinorus, Isocerus, Micrositus, and Litoborus.

The Pedinini, as here considered, will consist of the two genera

Pedinus and Platyscelis only ; these are quite isolated, not only by

the structural characters already given, but also in general habitus.

In this tribe the sexual modification of the legs in the male becomes

extreme.

The Tenebrionini will comprise the genera Tenebrio, Alephus,

Eupsophus, Opatrinus and the Blapstini—including Cabirus—as

well as the European Calear, Scleron and Pachypterus. Doliema

Pasc. (Adelina Lee. nee Woll.) and Bius* should be removed to the

Ulomini. It will be noted in extenuation of this radical change that

the general habitus of Tenebrio is very satisfactorily reproduced in

' This name is proposed in order to distinguish the tribe from the group

Opatrini, rendered necessary by the word Opatrinus.

? I have not been able to study this genus in nature but infer that it is

properly placed.

° In Bius the reflexed elytral edges and epipleure terminate abruptly before

attaining the apex; this and many other characters ally it to Uloma and

exclude it from the Tenebrionini. The European Dilamus is closely related.

the Blapstini, and especially in Mecysmus, but Eupsophus appears

out of place in any of the tribes thus far proposed. The genera

Genera as given below

The Opatrumini will include Opatrum, Gonocephalum, Scleropa-

trum, Pseudolamus, Melambius, Heterophilus, Opatroides, Hadrus

and Ephalus. Of these genera, the only ones found within the

nearctic region are Gonocephalum and Ephalus. Our single repre-

sentative of Gonocephalum was described by LeConte as Blapstinus

latifrons; it is entirely congeneric with the European forms, and

appears to be not only rare but very restricted in habitat; it occurs

in Vancouver Island. Lphalus latimanus is well known in cabi-

nets, but is somewhat rare; it is found in the Atlantic region, and

is not very closely related to any other genus.

The Amphidorini will of course remain as at present known.

The Leichenini, as here considered, consist of a few singular

genera previously distributed among, or forming several groups of,

the Opatrini of Lacordaire, but which have in common a very

strong bond of affinity ; in fact in spite of the difference in vestiture

Ammodonus and Microzoum are comparatively closely allied. It

will be noticed that the constancy and consequent taxonomic value

of the epipleursee becomes completely lost in the present tribe,—as

is also the case in the Ulomini. The genera may be defined as fol-

lows, those which are not nearctic being indicated by an asterisk :—

Anterior tibie strongly dentate or produced externally at or near the apex.

Eyes nude, completely divided or extremely nearly so; epipleure entire.

Anterior tibize very short and robust; eyes rather finely faceted.

*Microzoum

Anterior tibie slender; eyes much larger, coarsely faceted.

Ammodonus

394 Coleopterological N otices.

Eyes emarginate anteriorly, coarsely faceted, the facets separated by coarse,

and very strongly elevated caring; epipleure imperfect, wide near the

base, very narrow near the apex and completely obsolete in the middle.

*Leichenum

By this arrangement the Pimeliini and Pedinini are entirely, and

the Eulabini and Opatrumini chiefly, characteristic of the eastern

hemisphere, while the Upini and Tenebrionini are most numerous

in the western world. The Amphidorini are peculiar to western

North and South America, while the Blaptini, Scaurini and Leich-

enini are almost equally represented in the eastern and western

continents.

ELEODES Esch.

The genera of Blaptini are closely allied and, in general, mutually

distinguishable only by some single structural difference ; even this

is not always of definite and unequivocal value. The European

Prosodes, for example, is extremely close to Eleodes and differs, as

far as can be clearly perceived, only in the strong compression of

the four posterior tarsi. Guaptor differs only in the complete ex-

tinction of one of the spurs of the anterior tibiz and the abnormal

development of the remaining one, a character which the casual

study of our species of Eleodes will tend to prove of doubtful im-

portance. I think, also, that it will be found difficult to state any

absolutely constant difference between the females of Blaps and

Eleodes. It is true that the mentum varies, but in this respect the

difference in the form of this organ among the various species of

Eleodes, is vastly greater than that between Blaps mortisaga and

Lleodes suturalis. The form of the mentum is in fact of very little

value in this tribe, or indeed in many others of the Tenebrionide,

as an examination of the species of Eulabis or the sexes of Uloma

will amply demonstrate. .

Before describing several distinct forms of Eleodes which have

_ Coleopterological Notices. 395

come into my possession during the past five or six vears, it is

desirable to make a few observations:

1 The description of H. quadricollis given by Mannerheim reads

thus, in regard to the arrangement of the elytral punctures: ‘‘ Mas:

elytris . . . dense striato-punctatis, punctis granuliferis. Femina:

elytris . . . obsolete striato-punctatis.”

I have a specimen taken by myself near San Francisco, the

locality assigned by Mannerheim to quadricollis, which coincides

exactly with the above-described male of that species, and I there-

fore regard it as an authentic type; its length is 15 mm. while that

of Mannerheim’s type is 7 lin.

The description of guadricollis given by Horn (Rev. Ten., p. 309)

reads as follows, in regard to the elytra: ‘‘ Sculpture consisting of

punctures sometimes fine, at others rather coarse, rather densely but

irregularly placed and never muricate, never arranged in rows.”

The introduced italics indicate that the author quoted has mistaken

some other species—probably that described below as estriatus—

for the true quadricollis.

It should also be stated that a very large series of gentilis which

I took at San Diego, shows quite clearly that this species should be

associated with quadricollis and vicinus, and is out of place in the

present arrangement.

Finally the species named vicinus by LeConte is distinct from

quadricollis in having much finer punctures, which are sparser and

much less asperate toward the sides, and also in several other char-

acters, among which may be mentioned the form of the prothorax,—

widest at anterior third in quadricollis and just before the middle

in vicinus,—the much longer posterior tarsi in the male of vicinus,

and the form of the penis which is very much more slender and

attenuate in guadricollis. Vicinus is peculiar to the Gila Valley of

Arizona, a region zoologically quite distinct from that inhabited by

quadricollis.

2 The species described by me as arcuatus (Cont. Col. N. A.,

p. 47) belongs near carbonarius, and is not at all similar to extri- -

catus. It will be observed that in extricatus the elytral punctures

are arranged in closely approximate and equally pronounced series,

giving a peculiar appearance to this species. Cognatus Hald. is

simply a specimen in which the punctures are finer, but the disposi-

tion of them is precisely the same and cognatus is truly a synonym.

In carbonarius the elytral punctures are arranged in widely dis-

396 Coleopterological Notices.

tant and strongly pronounced rows, with a very few fine punctures

scattered along the intervals,—a radically different arrangement

which is reproduced in arcuatus. Debilis and arcuatus while

allied to carbonarius are easily distinguishable from it and from

each other; they are, in fact, specifically valid in every sense and

should be restored to the list.

3 The species longicollis and giganteus when normal have the

elytra smooth, polished and very minutely, sparsely punctate, the

punctures being distributed without order, but occasionally the elytra

have closely approximate series of large very shallow dents, which

are not true punctures, for on close examination the true punctures

are still seen to be distributed irregularly over the surface, some-

times accidentally coinciding with the shallow fovew, but generally

not. This is a remarkable character, probably affecting also the

allied estriatus described below, although in the specimens at hand

there is no indication of it.

E. porcatus n. sp.—Body somewhat slender in the male, robust in the

female, shining, the pronotum very feebly alutaceous, black throughout,

moderately convex above, strongly so at the sides. Head moderate, somewhat

densely punctate, very coarsely so on the epistoma; antenne long and rather

robust, the third joint about four times as long as wide and fully as long as

the next two together, fourth nearly twice as long as wide. Prothorax about

one-fourth wider than long, the apex just visibly narrower than the base, very

feebly emarginate in circular arc, the angles slightly obtuse, very narrowly

rounded; base feebly, evenly arcuate; sides more strongly arcuate before the

middle, thence moderately convergent and gradually feebly sinuate to the

basal angles, which are very obtuse but not distinctly rounded; disk evenly

convex, finely, sparsely punctate, the punctures becoming rather coarse later-

ally but not very dense. Llytra about two and three-fourths times longer than

the prothorax and, in the middle, very slightly wider in the male and nearly

three-fourths wider in the female; base broadly, feebly emarginate, as wide

as the contiguous base of the prothorax in the male but distinctly wider in

the female, the apex very strongly declivous, not at all produced, narrowly

rounded—viewed posteriorly—disk very deeply suleate, the sulci finely, rather

" sparsely and muricately punctate, the intervals equal in width to the sulci,

_ very convex, finely, sparsely punctate. Spurs of anterior tibie slender and

pointed, unequal but more strongly so in the male. Length 18.0-19.0 mm. ;

width 6.0-8.8 mm.

Arizona (Fort Apache).

The three specimens before me indicate a species belonging near

obsoletus, but not very closely allied to it. The size is very much

larger, the elytra more deeply sulcate, the sulci finely punctate and

Coleopterological Notices. 397

the intervals narrow and extremely convex; in obsoletus the sulci

are always very coarsely punctate and the intervals wide and flatter.

Porcatus further differs in its prolonged and prominent prosternal

process, in its longer antenne and in its very much longer and more

robust tarsi.

E. cuneaticollis n. sp.—Rather slender in the male, robust in the

female, moderately convex, rather shining, the pronotum feebly alutaceous ;

elytra coarsely rugulose. Head rather large, more than one-half as wide as

the prothorax, very coarsely, deeply and rather densely punctured ; antennz

short and robust, distinctly shorter than the head and prothorax, third joint

two and one-half times as long as wide, fully as long as the next two, fourth

but very slightly longer than the fifth. Prothoraxr from one-third to two-fifths

wider than long, the apex nearly as wide as the base, broadly, very feebly

emarginate in circular are, the apical angles slightly obtuse, very narrowly

rounded and not in the least prominent ; base subtruncate, the angles slightly

obtuse, not distinctly rounded but not noticeably prominent; sides strongly

arcuate anteriorly, conspicuously convergent and almost perfectly straight in

basal two-thirds ; disk widest at apical third, broadly convex above, strongly

convex and declivous at the sides, rather sparsely, coarsely and deeply punc-

tate, the punctures about twice as large and distant as those of humeralis.

Elytra distinctly less than twice as long as the prothorax and from one-fourth

to two-fifths wider than the latter, at base equal in width to the contiguous

base of the same, rather abruptly declivous and pointed at apex; humeri

obtuse, not rounded, not in the least prominent; disk rather depressed above,

gradually strongly convex and declivous toward the sides, very coarsely,

deeply and densely punctate, the punctures irregularly arranged without

trace of impressed strie, not muricate but producing a strongly rugulose

appearance by mutual semi-coalescence. Legs short and somewhat robust ;

spurs of anterior tibiz rather slender but extremely unequal, the anterior

more than twice as long as the posterior in the male, less unequal, the ante-

rior about one-third longer than the posterior, although much more robust and

obtusely pointed in the female. Length 14.0-15.0 mm.; width 5.2-6.9 mm.

California (exact locality unknown).

This species belongs near humeralis but differs in four important

characters, viz: the much shorter and more robust antenne and

legs, the unexposed humeri, the very much coarser and deeper

elytral sculpture and coarser, sparser pronotal punctures, and finally

the smaller and much léss unequal spurs of the anterior tibiz in the

male, the larger spur in humeralis being nearly four times as long

as the smaller one. In considering this enormous disparity in size

of the spurs, attention is redirected to the conditions existing in

Gnaptor, alluded to in the introductory remarks to the present genus.

398 Coleopterological Notices.

E. estriatus n. sp.—Moderately robust, strongly convex, smooth and

highly polished, the pronotum very slightly alutaceous. Head rather trans-

verse, moderate in size, rather coarsely punctate, the punctures sparse toward

the middle, very dense and setose laterally ; antenne rather short and robust,

the third joint very slightly longer than the next two together, fourth less

than twice as long as wide. Prothorax just visibly wider than long, the apex

truncate, equal in width to the base which is subtruncate; sides broadly

arcuate anteriorly, convergent and nearly straight in basal half, the basal

angles very obtuse and not at all prominent; disk moderately convex, very

finely and sparsely punctate throughout. /ytra about three times as long as

the prothorax, widest behind the middle and about two-fifths wider than the

prothorax, at base equal in width to the base of the latter, the humeri not

rounded but also not prominent; apex acute but not greatly prolonged; disk

moderately declivous behind, finely but distinctly and very sparsely punctate,

the punctures not asperate, not denser laterally and arranged without trace

of order throughout. Length 17.8-26.0 mm. ; width 6.5-9.7 mm.

California (San Francisco).

The two specimens before me differ very greatly in size but are

exactly of the same form, the legs, however, in the small specimen,

are relatively longer and more slender than in the larger one, in

which they are unusually short and robust when compared with

longicollis or giganteus, to which this species is allied. It differs

from the former in its broader more anteriorly dilated prothorax,

much shorter and rather more robust antennz and coarser punctua-

tion, and from the latter in the smaller size, less attenuate form,

wider epipleure, less convex pronotum, less arcuate sides of the

prothorax, shorter elytra and many other characters. In giganteus

the elytra are generally but slightly less than four times as long as

the prothorax.

The anterior tibial spurs in estriatus are rather slender, similar

and very slightly unequal in length; in the larger specimen they

appear to be relatively a little longer. I am therefore uncertain as

to whether the two specimens are both males or both females, or

whether the smaller is a male the larger a female; I am inclined

however to think that the latter may be the case as if my memory

is correct they were taken at the same time.

Although giganteus is said by Horn (Rev. Ten., p. 312) to occur

near San Francisco, I have never found it in that locality, but have

it from San Diego which is also the locality assigned it by LeConte

in a penciled note. Longicollis does not oceur within the true

Pacific coast fauna.

Coleopterological Notices. 399

E. tarsalis n. sp.—Body inflated in the female, more slender in the male,

nearly smooth, strongly shining. Head rather strongly transverse, coarsely

and strongly punctured at least toward the edges; antenne rather short and

robust. Prothorax distinctly wider than long, the base and apex nearly equal,

subtruncate ; basal angles very obtuse, sometimes very slightly prominent when

viewed vertically ; sides rather strongly arcuate anteriorly, straighter and

rather strongly convergent in basal half; disk moderately convex, sparsely,

finely but very distinctly punctate. /ytra about two and three-fourths times

as Jong as the prothorax, at base slightly but distinctly wider than the base

of the latter, the humeri very narrowly rounded but quite prominent; disk

strongly, deeply punctate, the punctures generally simple but becoming muri-

cate, although not denser, toward the sides, rather sparse throughout and dis-

tributed without trace of order. Length 19.5-21.0 mm. ; width 7.3-9.3 mm.

California (Mount Diablo).

The single pair which I took at the indicated locality, near San

Francisco, displays considerable sexual divergence, the male being

moderately robust, with the elytra about two-fifths wider than the

prothorax and the posterior tarsi very nearly three-fourths as long

as the tibie. In the female the prothorax is more transverse and

but slightly more than one-half as wide as the elytra, the posterior

tarsi being much shorter.

The present species belongs near quadricollis but may be distin-

guished by the nature of the punctuation, which is not arranged in

series on the elytra, and by the prominent humeri and broader base

of the elytra, also by the very much longer and thicker posterior

tarsi of the male. The anterior spur of the anterior tibia is longer

and much more robust in the female, but is feebly arcuate and

acutely pointed.

KE. temuipes n. sp.—Moderately slender, convex, rather smooth and

shining throughout. Head finely, sparsely punctate; antenne long and

slender ; third joint about five times as long as wide and nearly as long as the

next three together. Prothorar rather more than twice as wide as the head,

about as long as wide; apex very nearly as wide as the base, broadly, feebly

emarginate in circular are, the apical angles very acute and in the form of

small everted teeth ; base broadly, very feebly arcuate ; basal angles extremely

obtuse; sides almost evenly and distinctly arcuate; disk widest just visibly

before the middle, rather strongly, evenly convex throughout; sides minutely

beaded; surface feebly alutaceous, minutely and very sparsely punctate.

Elytra elongate-oval, exclusive of the caudal prolongation four-fifths longer

than wide, a very little more than three times longer, and, in the middle, two-

thirds wider than the prothorax ; sides evenly arcuate ; humeri not prominent,

the two bases equal in width; disk with distant unimpressed rows of fine

simple moderately approximate punctures, the intervals each with a single

400 Coleopterological Notices.

line of still finer and extremely widely spaced punctures, which are generally

simple, but which laterally toward apex become very coarse sparse asperities.

Total length 30.5 mm.; width 10.0 mm.

Texas (El Paso). Mr. G. W. Dunn.

The single type is a male and represents a very distinct species,

combining the characters of gracilis and luce. The legs are long

and extremely slender, the anterior femur with a strong spiniform

tooth. The prothorax is almost as in gracilis, but is longer, while

in the male the elytra are prolonged by a caudal appendage which

is nearly one-fourth as long as the elytra. From duce it differs in

its small dentiform and everted apical angles of the prothorax, and

more feeble apical emargination.

Asa very singular character, it will be noted that it is the very

inconspicuous punctures of the intervals which become, toward the

sides of the apical portions, the large strong and very conspicuous

asperities, the fine punctures of the regular series remaining almost

unmodified, but becoming slightly asperate very near the apex and

on the caudal prolongation.

E. subcylindricus n. sp.—Form cylindrically convex, rather slender,

finely very strongly alutaceous and smooth throughout, black; elytra casta-

neous. Head moderate, sparsely and rather finely punctate; antenne rather

long and slender, about as long as the head and prothorax, third joint nearly

four times as long as wide. Prothorax subcylindrical, about one-fifth wider

than long, transversely moderately but very evenly convex throughout, longi-

tudinally very feebly convex ; apex very nearly as wide as the base, subtrun-

cate between the acute, very strongly advanced but not at all everted apical

angles; base broadly, very feebly arcuate, the angles obtuse, not in the least

rounded, not at all prominent; sides evenly and feebly arcuate throughout ;

disk very sparsely and extremely minutely punctate throughout. L/ytra more

than three times as long as the prothorax and rather less than one-third wider ;

base very feebly emarginate, exactly equal in width to the contiguous base

of the pronotum; apex narrowed rather gradually in apical third, acutely

rounded at tip; sides feebly convergent and arcuate near the humeri, parallel

and almost perfectly straight thence to posterior third; humeri very obtuse,

not rounded, not at all prominent ; disk with unimpressed distant rows of very

small, nearly simple punctures, the intervals with single rows of extremely

widely distant but almost similar punctures, the punctuation not denser

toward the sides. JZegs long and very slender; anterior femora with a small

but acute tooth slightly beyond apical third, the remaining femora simple but

with the groove of the lower edge fine, very deep and conspicuous, extending

almost to the base, with the cariniform edges finely, unevenly serrate; tibiw

strongly arcuate, spurs of the anterior short, nearly equal and slender.

Length 21.0-23.0 mm. ; width 7.5-7.8 mm.

Arizona (exact locality unknown). Mr. G. W. Dunn.

The two examples before me are almost perfectly similar in every

respect, but the peculiar coloration may nevertheless be due to im-

maturity.

This species is totally distinct in general habitus from any other

which, is known to inhabit the United States, and is not described

in the Biologia Centrali-Americana; although far removed from

gracilis, it may be placed near it for the present.

E. promimens n. sp.—Form somewhat as in dentipes, convex, smooth

and alutaceous throughout. Head moderate, finely, sparsely punctate, more

densely so toward the sides of the epistoma; antennez short and very robust,

much shorter than the head and prothorax, third joint about twice as long as

wide and equal in length tothe next two. Prothorax about one-sixth wider

than long; apex and base subequal, the former broadly arcuate, sinuate later-

ally, the apical angles being acute, very prominent anteriorly and distinctly

everted ; base broadly, evenly, very feebly arcuate; sides broadly arcuate

anteriorly, rather strongly convergent in basal half and strongly sinuate near

the basal angles, which are acute and prominent; disk rather strongly convex

throughout, finely and sparsely punctate, strongly alutaceous, the side mar-

gins very minutely beaded. Scutellum strongly transverse, broadly rounded

behind, highly polished and impunctate. lytra at base broadly, feebly

-emarginate and about as wide as the contiguous base of the prothorax, gradu-

ally narrowed and acute at apex; sides evenly arcuate; humeri obtuse but

not rounded, not prominent; disk widest at the piiddle, where it is rather

more than one-third wider than the prothorax, feebly alutaceons, finely,

sparsely punctate, the punctures nearly simple, arranged in widely distant,

rather feebly defined, unimpressed rows, the intervals with a few widely dis-

tant and nearly similar punctures. Legs rather short and slender, the anterior

femora with a short obtuse tooth near outer third; middle and hind femora

simple; spurs of anterior tibie moderate in length, slender, similar and very

nearly equal. Length 19.0 mm.; width 7.8 mm.

California (San Luis Obispo Co.).

I obtained a single specimen of this very distinct form at Port

Harford. It belongs near dentipes but is more robust, the elytra

being shorter, the prothorax is, however, much narrower, the sides

being convergent and nearly straight from the middle. One of the

chief differences lies in the antennal structure, the third joint being

very much shorter; in dentipes the antenne are very nearly as long

as the entire head and prothorax and are much more slender.

E. elegans n.sp.—Moderately robust, strongly convex, strongly alutace-

ous, the elytra moderately shining ; integuments nearly smooth. Head mode-

rate, somewhat finely, sparsely punctate; antenne rather short but slender,

not quite as long as the head and prothorax, third joint about two and one-half

times as long as wide, scarcely as long as the next two, fourth much longer

than the fifth. Prothorar nearly one-third wider than long, the apex a very

little narrower than the base, transversely truncate, the apical angles small

but acute, anteriorly prominent, dentiform and feebly everted; base very

feebly, evenly arcuate ; sides strongly, almost evenly arcuate throughout, the

basal angles very obtuse, not rounded but not in the least prominent; disk

rather strongly convex throughout, widest just before the middle, somewhat

sparsely but deeply and rather coarsely punctate ; side margins very minutely

beaded. lytra about three times as long as the prothorax, and at base, just

visibly wider than the base of the latter, gradually acute at apex, inflated,

widest in the middle where they are about three-fourths wider than the

prothorax ; sides evenly arcuate; humeri obtuse but not rounded, not at all

prominent; disk confusedly, finely creased, rather coarsely and distinctly

granulato-reticulate, very finely and sparsely punctate, the punctures nearly

simple throughout and not denser laterally, arranged in very feebly defined

unimpressed rows, approximate toward the suture, then widely distant, with

an uneven and sparser row along the middle of the intervals. Legs moderate

in length and very slender ; anterior femora not dentate but with a very broad

and obtuse rounded salient near the apex; spurs of the anterior tibiwe very

slender and almost exactly equal. Length 13.0 mm.; width 6.0 mm.

California (Hoopa Valley, Humboldt Co.).

The unique type of this species is one of the most symmetrically

proportioned insects of the family. There is no described species

with which it can be gompared, but for the present it may he placed

near dentipes.

E. brummipes n. sp.—Rather robust, moderately convex, coarsely,

densely sculptured and dull, black; legs dark brown throughout. ead

large, fully two-thirds as wide as the prothorax, coarsely, extremely densely

punctate and scabrous ; antennz longer than the head and prothorax, rather

slender, third joint about four times as long as wide. Prothorax scarcely one-

third wider than long; base and apex very nearly equal in width, subtrun-

cate; apical angles obtuse, not distinctly rounded, not at all prominent; basal

right, not rounded ; sides strongly angulate at the middle, thence very feebly

arcuate to the apex and broadly sinuate to the base; disk moderately, evenly

convex throughout, very coarsely, deeply and confluently punctate. Elytra

at base nearly one-third wider than the contiguous base of the prothorax,

very slightly more than twice as long as the latter, abruptly and obtusely

rounded behind when viewed vertically ; sides strongly arcuate behind, gradu-

ally convergent and straighter thence to the humeri, which are slightly obtuse

but scarcely at all rounded; disk widest behind the middle, where it is from

one-third to two-fifths wider than the prothorax, feebly convex above, strongly

so laterally, coarsely, densely, asperately punctate, the asperities arranged

without trace or order. Legs moderate in length, somewhat slender. Length

9.2—9.5 mm.; width 4.3-4.6 mm.

Coleopterological Notices. 403

Idaho; Wyoming.

One of the smallest species of the genus and quite isolated ; it is

somewhat allied to pimelioides although very much smaller. In

ptmelioides the sides of the prothorax are arcuate, and only sinuate

for a short distance before the basal angles, and the sculpture of the

elytra consists of rounded flattened tubercles which are generally

arranged in very distinctly traceable approximate rows; the legs

are black and the head very much smaller when compared with the

prothorax, which is much more transverse; the humeri are broadly

rounded. The species described by LeConte as viator does not

differ from pimelioides, the type being perfectly identical with the

ordinary maies of that species.

EMBAPHION Say.

E. laminatum n. sp.—Moderately robust, the male more slender, black

and dull throughout. Head small, very finely, sparsely and subasperately

punctate; antenne slender, third joint from four to nearly five times as long

as wide, eighth one-half longer than wide. Prothorax about one-half wider

than long, the median portion very feebly convex, fully as long as wide, and:

having two feeble, subparallel and sinuous impressions near the middle of the

disk ; side margins very widely and strongly reflexed, the outer edges parallel,

strongly and evenly arcuate throughout, the basal angles broadly rounded and

projecting beyond the transverse median portion of the base; apex strongly

emarginate, the emargination not quite three times as wide as deep; surface

throughout finely, extremely sparsely and subasperately punctate. £/ytra

from one-half to four-fifths longer than wide, at base transversely truncate,

the sides very thin and broadly but not abruptly reflexed, the acute lateral

edges parallel and feebly arenate in basal two-thirds, then ronnded to the

apex and slightly prolonged, uniting in a prolongation of the suture; humeri

rounded ; disk distinctly wider than the prothorax, each elytron broadly con-

cave, the suture elevated ; surface with approximate, imperfectly defined and

feebly impressed rows of rather coarse, impressed punctures, also finely and

sparsely asperate. Inflexed sides of the elytra nearly flat, somewhat coarsely

and sparsely but unevenly punctate, the epipleure very imperfectly defined

except near the apex. Jegs very slender. Length 14.0-15.0 mm.; width

6.8-7.5 mm. ‘

Texas (El Paso). Mr. G. W. Dunn.

The elytral punctures referred to in the description are merely

impressed fovez, and do not appear to be in the least setigerous;

the finer but strong and sparse asperities are distributed over the

surface without regard to the punctures, and each bears a strong

thick semi-erect seta—see third remark under Eleodes.

Anyaus N. Y. Acap. Scr., V, Nov. 1890.—27

404 Coleopterological Notices.

This species is related only to contusum Lec., but differs greatly

in the upper surface of the elytra. In confusum the elytra are

nearly flat, sometimes feebly and transversely convex, the side

margins being very narrowly but abruptly reflexed, while in lam¢-

natum the upper surface is broadly, strongly concave throughout,

the concavity of the general surface extending unbroken to the

extreme edges; the elytral suture is however distinctly elevated, so

that it might be more proper to say that each elytron is concave ;

the humeral portion of the side margins is as usual a little more

strongly reflexed. The prothorax and the conformation of the

posterior angles are almost exactly as in contusum, except that the

sides are more widely reflexed. In contusum the pronotum is fully

twice as densely asperate.

EULABIS Esch.

The species of this genus are not closely allied among themselves

and may be easily identified from the original descriptions; the

following species is, however, somewhat similar in appearance to

rufipes although twice as large.

E. crassicormis n. sp.—Oblong-elongate, not pubescent, moderately

convex, dull, very dark rufo-piceous throughout, the legs just visibly paler.

Head moderate, about one-half as wide as the prothorax ; upper surface flat,

rather finely, extremely densely, confluently punctate throughout and dull ;

sides not perceptibly reflexed, the eyes rather depressed ; antennz not quite

as long as the head and prothorax, very robust, strongly compressed and

incrassate toward apex, second joint much shorter and narrower than the

fifth. Prothorax about one-third wider than long; apex but very slightly

narrower than the base, subtruncate, the apical angles narrowly rounded and

slightly prominent anteriorly; base truncate, very broadly, feebly sinuate

toward the basal angles which are not at all rounded and generally minutely

prominent, the sides being sinuate for a short distance before them; sides

strongly, evenly arcuate; disk feebly convex, rather depressed toward the

very finely reflexed side margins, somewhat coarsely, very deeply and densely

punctate, the punctures longitudinally coalescent. Scutellum not entering

the elytral disk. £lytra scarcely more than twice as long as the prothorax

and but just visibly wider than the latter, otherwise very nearly as in rufipes.

Abdomen densely very coarsely and deeply punctate, the sete rather long and

distinct. Length 7.0-7.8 mm.; width 3.1-3.3 mm.

pressed, the two fovee separated by a strong thick and tumid carina

which becomes much less prominent toward base; this is also very

nearly the form in rufipes.

This species differs from rufipes in antennal structure and in its

larger size, more robust and depressed form, more transverse pro-

thorax, much longer and more conspicuous abdominal sete and in

the structure of the penis; the latter in rufipes is very slender,

perfectly flat throughout and gradually acuminate, while in crassi-

cornis it is more robust and has a transverse tumid elevation on

the upper side at the apex. The second antennal joint in rwfipes

is as long as the fifth and very nearly as wide in both sexes.

figures are given of the posterior femur of all the species included

in the table, and that of bicolor has been drawn directly from the

original type in the cabinet of LeConte; this type corresponds

exactly with a large series in my own cabinet, collected near the

The first ventral segment is strongly and transversely tuberculate

in the middle in the male. This species is larger, blacker, duller

and more densely punctate than bicolor.

The single specimen represents a species resembling bicolor some-

what in general habitus, but differing in its longer and much more

densely punctate head, more convex elytral intervals near the apex

and several other characters.

C. fuscipilosus n. sp.—Form robust, convex, shining, very densely

clothed throughout with fine, long, erect, brown-black hairs. Head moderate,

densely and rather coarsely punctate; antenne rather long and robust, but

very feebly incrassate toward apex, third joint fully three times as long as

wide. Prothorax from two-fifths to one-half wider than long, convex, strongly

rounded at the sides, which are very strongly convergent near the base and

sinuate for a very short distance before the basal angles the latter being very

small but acute and prominent; apical angles prominent acute dentiform and

Southern California.

The pubescence is nearly similar in color to that of Amphidora

nigropilosa, but while in C. fuscipélosus the hairs are all alike, the

pubescence is dual in composition in the species referred to, there

being a system of long blackish hairs which are erect, and another

system of shorter, more appressed and paler ones.

This species belongs near osculans, but differs not only in the

color of the pubescence, which is quite constant throughout the

series of four specimens before me, but in its greater density, also

in the much more robust and compact form of the body, the pro-

thorax being shorter, more transverse and more nearly equal in

width to the elytra. ;

The hind tibiz of the male have a strongly developed acute

oblique tooth near apical third as in osculans.

IPHTHIMUS Trugui.

Our western forms, allied to serratus, may be distinguished as

Pronotum coarsely, very densely punctate throughout, the punctures gener-

ally subconfiuent toward the sides, general surface lustre opaque.

tate; antenne very robust. Protherax about one-half wider than long, the

apex truneate and very distinetly narrower than the base, the latter trans-

verse and broadly, feebly bisinuate; basal angles acute and prominent; sides

parallel and strongly arcuate in apical two-thirds, then strongly convergent

strongly convex, declivous toward the sides which are very narrowly reflexed,

very sparsely and minutely punctate, more coarsely but scarcely more densely

This is one of the largest species known to me, and is very dis-

tinct from Jews? in its much more robust form, more transverse

prothorax, declivous base of the elytra and unimpressed striz.

The two species /evissimus and lewitst are further distinguished

from serratus and sublevis by the somewhat longer head, less

widely flattened and explanate sides of the pronotum and truncate

apex, the apex of the prothorax being relatively wider and broadly,

feebly sinuate in the latter of the two groups.

The characters originally employed by LeConte and subsequently

do not seem to be sufficiently concise or decisive to distinguish the

genera in a satisfactory manner. The form of the intercoxal pro-

jection of the abdomen, for example, varies so little throughout the

group that mistakes are absolutely unavoidable in attempting an

identification from the form of this process. The characters bor-

rowed from the general form of the antenne are also unsatisfactory.

The group is essentially American, there being to my knowledge

but a single palearctic genus which can be included; this genus—

Cabirus Muls.,—comprises a very few small species, apparently

confined to Asiatic Turkey and the neighboring regions.

The following study has been carefully made with the hope that

these obscure and neglected little insects may be thereby some-

what better understood. They are in no wise difficult to identify,

except in certain parts of the very large genus Blapstinus, the

species being unusually clearly defined and constant for the Tene-

brionidz, where the great specific variation in outward form is so

familiar to us in Eleodes.

The genera are very readily separable into two distinct sections

as follows :—

I.—Body always winged, the wings sometimes very rudimentary ; scutellum

normal, triangular, distinctly separating the elytra at base, and having a wide

polished impunctate and generally semi-coriaceous border; anterior tarsi of

the male usually dilated.

Anterior tibie bent, more strongly so in the male; pubescence dual in

TRICHOTON Hope.

On reading the description given by Champion of the species 7’

lapidicola and 7’. curvipes, there is very little reason for doubting

that our Blapstinus sordidus should also be referred to the same

genus. In 7’. sordidum the eyes are completely divided; the genus

therefore belongs to the Blapstini and in no wise to the Opatrini,

where it was placed by Lacordaire.

Trichoton is very closely allied to Blapstinus, resembling it in

nearly all details of structure, but departs widely therefrom in the

form of the anterior tibiz and in the nature of the vestiture. The

latter is of dual structure, consisting of finer, but still rather short

coarse and recumbent hairs, and longer erect and very robust bris-

tles, irregularly scattered in clusters on the elytra; these bristles

are very peculiar, as will appear below. The eleventh joint of the

antenn also differs in form.

T. sordidum Lec.—Blapstinus sord.: Ann. Lye. N. Y., V, p. 146.—

Oblong-oval, moderately convex; integuments somewhat shining, piceous,

but almost completely concealed by the very dense ochreous-yellow vestiture,

which on the elytra is finely and confusedly mottled with patches of dark

brown bristles; legs and antenne rufo-piceous. ead strongly transverse,

strongly rounded throughout anteriorly, the epistoma deeply sinuate in the

middle, somewhat finely but very deeply and densely punctate; upper lobe

of eyes rather large, rounded ; antenne robust, a little shorter than the head

and prothorax, somewhat feebly incrassate toward apex, third joint more than

twice as long as wide but distinctly shorter than the next two together,

eleventh fully as wide as the tenth, rather longer than wide, ovate, obliquely

pointed at apex. Prothorax fully twice as wide as the head and about twice

as wide as long; apex very much narrower than the base, very deeply emar-

ginate, the angles right, not at all rounded and anteriorly prominent; base

transverse, the lateral sinuations wide and very deep; basal angles nearly

similar to the apical, very slightly acute; sides strongly and evenly arcuate

throughout; disk widest a little before the base, very broadly and abruptly

explanate at the sides throughout the length, rather finely but very deeply

and densely punctate thronghout, the coarse bristles and coarse recumbent

hairs almost evenly intermingled, the latter condensed in two small discal

spots. Scutellum triangular, distinct, densely pubescent, the smooth border

very narrow. lytra behind the middle very slightly wider than the protho-

rax, nearly three times as long; sides almost straight toward base, arcuate

behind; apex rather narrowly rounded; disk with rather fine, moderately

impressed strie which are closely and not very coarsely punctate; intervals

the third interval, very obscurely but rather densely punctate, each puncture

of each segment.

Male.—Anterior tibie strongly, inwardly bent near apical third, the inner

outline being obtusely and angularly emarginate, the outer strongly, evenly

arcuate toward apex ; intermediate tibize with a small internal notch near the

“apex; anterior tarsi just visibly wider; abdomen broadly, very feebly im-

pressed in the middle toward base.

Arizona.

The.anterior and middle tarsi in both male and female are densely

clothed beneath with long fine hair, which however is a little coarser

in the female; in both sexes the hind tarsi are coarsely spinose

beneath. In the female the anterior tibie are feebly bent in apical

third, the inner line being broadly sinuate; the entire tibia, how-

ever, is rather more robust than in the male.

The coarse bristles of the dorsal surface, to which allusion has

been made, are of extraordinary form, being triangular in trans-

verse section; they are equal in thickness throughout the length,

and the apex is transversely truncate.

The punctures of the elytral strive are very obscure unless the

specimen be rubbed, as in nature the integuments are covered with

a dull exudation.

_ This species is not at all rare but appears to be rather local, being

confined to the Gila Valley and the higher regions to the eastward

in southern Arizona.

ULUS Horn.

In this genus the form is more robust and elliptical than in

Trichoton, and the presence of well-marked fimbriz at the sides of

the pronotum and elytra, together with the very dense, coarse and

conspicuous pubescence, gives the species a peculiar habitus. The

fimbriz are but rudimentarily developed in Trichoton and completely

wanting in Blapstinus.

The sexual characters are very feeble, the anterior tarsi being the

only part which is noticeably modified in the male, and even here

the dilatation is so excessively slight as to almost elude detection.

The males are much less abundant than the females and are gener-

ally a very little less robust.

The species burrow in loose sand or mud, the enlarged apex of

the anterior tibie being well suited for this purpose. They are

ing it probable that several additional ones will be discovered by

future collectors. The five species before me may be thus distin-

the prothorax. Prothorax more than twice as wide as long ; apex three-fourths

feebly arcuate in the middle, very slightly sinuate laterally, the basal angles

not projecting as far behind as the median lobe; sides evenly and distinctly

arcuate; disk rather coarsely and deeply, somewhat unevenly and sparsely

I took a single representative of this species at the indicated

locality, and subsequently received a large series collected there by

Mr. Dunn. Fimbriatus is somewhat allied to obliquus but differs

in its smaller size, shorter and more transverse head and prothorax

with less oblique sides of the latter, rather larger eyes, shorter and

coarser vestiture, unimpressed and more finely punctured elytral

strie and flat intervals. The surface also seems to be more highly

polished. The elytral strize become feebly impressed toward the

sides, but the intervals remain flat.

This species is similar in form to fimbriatus, but differs in its

smaller size, coarser and more distant strial punctures, larger eyes,

shorter pronotal fimbrize and many other characters; it is peculiar

to the sand dunes which line the ocean beaches, and I have taken it

Texas.

A considerable series of this distinct species is before me, collected

at various points in Texas, and among them are several examples

taken at Columbus by Mr. Schwarz. Most of the specimens are

covered more or less thoroughly with a dense indurated mass of

argillaceous material, which from its appearance is undoubtedly the

all-pervading adobe mud, so characteristic of the southwest. Its

habits are therefore somewhat different from those of the majority

of species, which seem to prefer clean loose sand.

Elongatulus cannot readily be confounded with any other species

here described.

It is stated by Horn (Rev. Ten., p. 358) that this species occurs

near San Francisco; LeConte gives San Diego as the locality in

his original description. I have never seen it from the former

locality, but have specimens from Arizona. I think, therefore, that

the species probably belongs exclusively to the San Diego fauna.

The species is quite distinet from any other here deseribed in its

more oblong form, more parallel sides of the prothorax, and more

densely punctate, pubescent and rugulose elytral intervals, which

are alternately wider and more convex.

BLAPSTINUS Latr.

This is a rather large and somewhat composite genus, the chief

characters, subject to variations which in their several stages may

be regarded as of specific value, being the following, omitting for

the present any discussion of the minor characters, such as general

sculpture, punctuation, outline, magnitude of the eyes or structure

of the antenne, which can be well understood by inspecting the

table of species given below.

1—In regard to the hind wings it should be stated that the usual

idea, probably originating with Lacordaire, that some of the species

are apterous, is erroneous, all of our species being winged. The

wings are, however, extremely varied in development, sometimes

consisting of a mere slender cellular or membranous plate, less than

one-half as long as the prothorax, and in ether cases being fully as

long as the elytra, with every intermediate form. In no case do

they seem to be large enough, however, to give more than a labored

and feeble flight.

In the investigation of a genus such as Blapstinus, which becomes

in some parts very monotonous in the uniformity of specific type,

it is fortunate that we have so diversified an auxiliary character as

that afforded by the wings, and, as the individuals are generally

numerous, one at least can be spared for dissection in many doubt-

ful cases. In employing this character, however, it is undoubtedly

Coleopterological Notices. 417

necessary to allow a more or less extended latitude for variation

in the size of the wing, especially in the more rudimentary forms,

where complete inutility probably prevents the operation of any of

the laws of natural selection, which act so powerfully to maintain or

perfect the standard in those organs which, by reason of constant

utility, are continually brought under their influence. The present,

however, is perhaps not the best occasion to discuss the propriety

of using differential characters relating to rudimentary organs; it is

a subject requiring far wider study than I have been able to give it,

and it can only be said that any truth which the preceding hypo-

thesis may involve, has been guarded against by giving more weight

to the general shape of the wing than to size, unless the latter should

exhibit very decided divergence.

2__The vestiture varies conspicuously, but is always uniform in

structure. It may consist of suberect scales as in sulcatus, or of

hairs, more or less coarse or fine and generally subretumbent, as in

the majority of species; I have allowed considerable weight as an

auxiliary character to decided differences in size, color and length

of the hairs.

The vestiture of insects is too often confounded with, or con-

sidered analogous to the hairy covering of vertebrate animals, and

knowing to how great an extent the latter may vary, depending

upon climatic conditions of environment, we are sometimes too

hasty in concluding that the former must vary in the same way ;

this is, however, not the case, as a little thought will at once

demonstrate.

The hairy coat of the vertebrates, growing from a soft and sensi-

tive skin, is designed primarily as a protection from the vicissitudes

of the weather, or to retain the heat which would otherwise be

dissipated, to regulate the rapidity of evaporation, and to perform

other analogous functions depending upon the fact that vertebrates

are warm-blooded, internal-skeletoned animals.

In the articulates,—cold-blooded, external-skeletoned animals,—

the conditions are altogether different, and the vestiture, which in a

large proportion, for example of the Coleoptera, constitutes one of

the most diversified and wonderful characteristics of the organism,’

1 The vestiture is often extremely complicated. In Sitona, for example, it

is quadruplex, each of the four separate constituents probably having its own

sphere of utility. First there is a ground covering of wide rounded strigose

scales, generally densely placed, secondly a system of short robust piceous

subserves a different purpose and is not apparently subject to change

from any of those conditions which affect the hirsute covering of

the warm-blooded animals. This-is true at any rate of those hairs

which are termed tactile and which are very plainly of functional

value, but may possibly not apply so rigidly to other forms of

vestiture which, for want of any other name, we call ornamental ;

the degree of structural variation even in these hairs or scales is,

however, comparatively slight as far as my experience has led me.

It is highly probable that this ordinary or ornamental pubescence

in insects is simply a degenerative modification of hairs, which in

their original state were tactile and sensory, but which have become

functionless through disuse and at the same time more or less changed

in structure.

3—A nother variable function is the degree of dilatation of the

anterior and intermediate tarsi of the male and the vestiture of their

under surface, these organs being,—in partial contradiction of all

generic diagnoses which have been heretofore published,—occasion-

ally completely undilated and spinose beneath, as for example in

brevicollis. In the more widely dilated tarsus the under surface is

always very densely spongy-pubescent. The two groups into which

I have divided the majority of our species, depending upon the

amount of dilatation, are of course unnatural, and it may occasion-

ally be difficult to distinguish the dividing line between them, the

more strongly dilated tarsi of the second group as in arenarius,

being approached by the more feebly dilated members of the first

group as in longulus. The only definite criterion which can be

given, is that in the feebly dilated tarsus the second and third joints

are never more than very slightly wider than the apex of the fifth.

The impression of the fifth segment is not strictly sexual, being

often visible in the female and is always variable; the impression

of the abdomen toward base is, however, peculiar to the male and

generally quite constant.

pointed or truncate spicules, usually aggregated in clusters, third a system of

very sparsely placed long white erect sete, and finally, each puncture of the

strie has a peculiar minute seta which is unlike any other part of the vesti-

ture. In addition to this the scales of the first system are, on the under

surface, often most beautifully and minutely fimbriate or plumose around the

circumference. To fathom the mysterious processes of nature which have

resulted in such complexity, or to explain how these four systems act in

mutual relationship, will most undoubtedly forever be beyond the pale of our

feeble understanding—we can only wonder.

It is hoped that the following table which is founded upon very

extensive material,’ may enable the reader to recognize most of our

species, but I am only too well aware, because of the considerable

number of forms which from lack of material I have left undescribed,

that there may be some doubt regarding absolute identifications in

some parts of the series. It is to be understood of course that in a

genus containing many species, and especially where each species is

abundant in individuals as is generally the case in Blapstinus, that

its members cannot all be equally pronounced or isolated, some of the

forms having more nearly the nature of varieties or incipient species

than others; but as it is quite impossible to conceive of any definite

criterion for distinguishing varieties from true species,—if indeed

there is any clearly limited line of demarcation,—I have preferred

at present to describe each form separately. It may be stated, how-

ever, that the two strongly marked forms pulverulentus of the true

Pacific fauna and rujfipes of the San Diego fauna, are each the

centre of several closely allied but apparently distinct species, pro-

bably developed in comparatively recent times, the first group con-

sisting of aqualis, funebris, pulverulentus, parallelus and inquisi-

tus, and the second of crassicornis, rufipes and elongatus; a vast

amount of study must be expended upon these and other derivative

forms before anything definite can be known about their true rela-

tionships. Jnterruptus also seems to be a species in process of

disruption into geographical races, but in this case the various

forms are not distinctly limited :—

New York; Minnesota; Colorado; Wyoming.

The series before me represents a wide range of distribution and

exhibits more or less variation, chiefly in coloration and in the

extent of interruption of the elytral series. In some specimens,

more especially the eastern, the striz are nearly as widely and com-

pletely broken up as in metallicus, while those from Colorado have

almost completely continuous series. The punctuation of the pro-

notum is rather denser in the western representatives, being some-

times almost subconfluent toward the sides, and the pubescence is

generally a little denser. One specimen from New York is as

strongly eneous as any specimen of mefallicus which I have seen,

but is more alutaceous in lustre.

This is an abundant species, distinguishable from metallicus by

its broader, more oblong form, more parallel and more densely

punctate prothorax and finer less interrupted strial punctuation.

broadly, rather strongly emarginate in circular arc; disk widest at about the

middle, moderately coarsely punctate, the punctures decidedly sparse toward

the middle, denser but not contiguous toward the sides; basal impressions

rather distinct. Scutellum rather small, the polished margin slightly de-

pressed. lytra nearly three times as long as the prothorax, equal in width

to the latter, just visibly wider in the female; sides feebly arcuate, rather

deeply excavated in the middle toward base, the punctures slightly finer and

denser along the middle of the first segment, fifth with an oval apical fovea.

Length 5.8-6.8 mm.; width 2.2—2.6 mm.

California; Arizona (Yuma).

A conspicuously distinet species, easily known by its rather elon-

gate parallel depressed form, highly polished integuments, very

short and sparse pubescence, and coarse elytral and abdominal

punctures. The wings are well developed, extending almost to the

apex of the elytra.

In this species the pronotal hypomera are not distinctly impressed,

and in several other characters it makes a closer approach to Mecys-

mus than any other.

7 B. walidus nv. sp.—Elongate-oval, moderately convex, dark blackish-

castaneous; legs piceo-rufous ; integuments rather distinctly alutaceous, the

elytra strongly but very minutely granulato-reticulate; pubescence rather

sparse but distinct. Head transverse, feebly convex, rather coarsely, deeply

punctate, the punctures finer and denser toward the edges; upper lobes of

eye large, separated by scarcely four times their own width; antenne rather

slender, gradually and feebly dilated toward apex, third joint rather long,

nearly as long as the first two together and but slightly shorter than the

fourth and fifth, seventh much longer than wide. Prothorar nearly three-

fourths wider than long, the apex very much narrower than the base, the

sides evenly and very strongly arcuate throughout; base transverse, the

lateral sinuations distinct ; disk much wider just behind the middle than at

base, the lateral basal impressions completely obsolete, the punctures rather

coarse, sparse near the middle where they are separated by about twice their

slightly wider than the latter; disk with rather feebly impressed striee which

are rather coarsely punctate, the punctures deep, perforate and generally

Separated by about twice their own diameters ; intervals five or six times as

wide as the strial punctures, nearly flat, finely and sparsely punctured.

Abdomen finely and very sparsely punctate, the pubescence moderate in length,

very sparse, flavate. Legs moderate.

Male.—Anuterior and intermediate tarsi nearly as in longulus; abdomen rather

narrowly and feebly impressed in the middle toward base, the punctures

broadly dense and rather coarser toward the middle of the basal segment,

fifth with a rounded impressed apical fovea.

California (southern).

The single specimen serving as the type of this species differs

from the male of longulus in its more convex upper surface, aluta-

ceous lustre, much longer pubescence, finer, sparser punctuation of

the abdomen, larger size and several other characters. The punc-

tures of the elytral strize are relatively not quite as coarse as in

longulus, although of the same general nature, and the intervals

are more finely punctured.

wide as, and much longer than the second ; both pairs densely spongy-pubes-

cent beneath ; abdomen toward base narrowly and distinctly impressed, fifth

segment very feebly impressed.

Length 6.4-7.5 mm. ; width 2.8-3.3 mm.

Florida; Texas (Galveston and El Paso),

There can be no doubt of the synonymy here proposed. The

species resembles dilatatus but differs in its somewhat narrower

form, rather more shining surface, coarser punctuation, sparser and

not longitudinally rugulose pronotal punctuation and longer nar-

rower prothorax, with less strongly arcuate sides. The specimens

collected by myself at the points in Texas named above do not differ

in the minutest detail from the unique Florida type of LeConte.

This is a very widely diffused species, occurring over the entire

southern portion of the North American continent.

9 B. dilatatus Lec.—Ann. Lyc. Nat. Hist. N. Y., V, p. 146.—Oblong,

rather feebly convex, black, rather feebly shining; pubescence moderate in

length, subrecumbent, somewhat stout, consisting of pale flavo-cinereous and

tremely densely punctate throughout, the punctures forming imperfect longi-

tudinal ruge. Scutellum small, polished, minutely not densely punctate.

Elytra about three-fourths longer than wide, equal in width to the prothorax

and rather less than three times as long; sides parallel and very feebly

arcuate, together somewhat acutely rounded behind; disk rather finely

striate, the strie very feebly impressed toward the suture, finely punctured,

the punctures round, moderately deep, becoming distinctly larger and deeper

laterally, generally distant by from one-half more than to twice their own

very finely, rather sparsely punctate. Abdomen polished, finely, rather sparsely

punctate, the pubescence fine, short, sparse and inconspicuous. Legs and

verse, the former slightly the wider; intermediate tarsi very feebly dilated,

first and second joints equal in width, both pairs with dense pads of coarse

spongy pubescence beneath ; abdomen narrowly and feebly impressed in the

middle toward base, the fifth segment with a feeble rounded impression.

Length 7.0-7.7 mm.; width 3.1-3.4 mm.

Southern California; Arizona.

A well-marked species, one of the largest of the genus, differing

from fortis, the only one to which it is allied, in addition to the

characters mentioned under that species, in its narrowly rounded

basal angles of the prothorax and slightly in the nature of the

pubescence, this being generally more uniform and homogeneous in

fortis. In the female of both of these species the anterior tarsi are

decidedly robust, but simply densely setose beneath. In fortis the

female is decidedly more robust than the male, this being more

noticeable than in dilatatus. In both, the hind wings are rather

well developed, being nearly as long as the elytra.

10 B. sonore n. sp.—Oblong, robust, moderately convex, dark reddish-

brown in color, the integuments dull and finely alutaceous, being very minutely

but strongly granulato-reticulate throughout ; pubescence short, very robust,

dense, bright reddish-yellow in color and conspicuous. Head very deeply,

by about five times their width; antenne moderate, gradually and feebly in-

crassate toward apex, the third joint much shorter than the next two. Pro-

thorax nearly four-fifths wider than long, the apex scarcely more than three-

fourths as wide as the base, the latter transverse, the sinuations strong; basal

angles right and very distinctly, although narrowly, rounded; sides evenly

and rather strongly arcuate; disk widest at the base, finely and very densely

punctate throughout, the punctures not greatly coalescent. Hlytra behind the

as long as the latter; sides feebly arcuate, broadly, parabolically rounded

behind ; disk rather finely striate, the striae somewhat abruptly and distinctly

impressed, the punctures moderately coarse, circular, deep, perforate and

generally very close, separated by scarcely their own widths ; intervals wide,

flat, fully seven times as wide as the strial punctures, very finely but not very

sparsely punctured. Abdomen shining, sparsely, somewhat finely punctate,

the pubescence rather long, fine, very sparse but distinct. Legs rather long

and slender.

Male.—Unknown.

Length 6.3 mm.; width 3.0 mm.

Mexico (Sonora).

The unique specimen is a female but is quite distinct froin any-

thing known to me, and apparently not described in the Biologia

Centrali-Americana. From the fact that the anterior tarsi of this

female are rather robust or subdilated, I am disposed to place it in

the section with strongly dilated male tarsi. It may be easily

known by its robust form—somewhat resembling dilatatus,—its

smooth but very dull surface, fine, dense pronotal punctuation,

evenly, closely punctured elytral strie, very wide flat intervals and

the coarse short ochreous-yellow and abundant pubescence.

11 B. castaneus n. sp.—Elongate-oval, somewhat depressed, moderately

shining, dark blackish-brown ; legs dark rufo-piceous ; pubescence moderate

in length and density, rather fine, dark fulvo-piceous and not conspicuous.

Head densely deeply punctate, moderately convex; epistoma very broadly,

rather feebly sinuate ; upper lobes of eye moderate or rather large, separated

by nearly five times their width ; antenne rather slender toward base, gradu-

ally and moderately incrassate toward apex, the third joint very much shorter

than the next two, eighth nearly as large as the ninth. Prothorax not very

strongly transverse, about one-half wider than long, the apex much narrower

than the base, broadly rather strongly emarginate in circular arc; base trans-

verse, the sinuations strong; sides almost evenly and strongly arcuate; basal

angles obtuse and generally very narrowly rounded; disk very deeply, rather

coarsely and extremely densely punctate, the punctures strongly, longitudi-

nally coalescent, forming short ruge toward the sides, generally not noticeably

sparser in the middle. Scutellum moderate, the polished margin distinct.

Coleopterological Notices. 433

Elytra subequal in width to the prothorax and about three times as long;

sides parallel and just visibly arcuate; apex parabolically rounded; disk

with coarse but rather feebly impressed striz which are coarsely and deeply

punctate, the punctures circular, perforate, generally separated by rather less

than twice their own diameters; intervals nearly flat, finely and sparsely

punctured. Abdomen moderately densely and not very finely punctured, the

pubescence moderately dense, distinct but not conspicuous. Legs robust.

Male.—Anterior tarsi strongly dilated, the second joint much longer than

the third ; intermediate more feebly but distinctly dilated ; abdomen narrowly

and very feebly flattened in the middle toward base.

Length 4.7-5.8 mm.; width 1.9-2.5 mm.

Texas (E] Paso); Arizona (Tugson) ; Colorado.

The typical forms of this species are from El Paso; those from

Tucson differ, and apparently form two varieties, in one of which

the strial punctures are more approximate, and in the other much

coarser with more deeply impressed strize. The two from Colorado

are black, and have the strie finer and more feebly impressed, the

strial punctures being very much smaller. JI am quite certain that

these variations indicate several distinct species, but the material

before me is not sufficiently extensive to enable me to define them

exactly.

The wings are well developed and as long as the elytra.

12 B. histricus n. sp.—Elongate-oval, widest behind the middle of the

elytra, very dark brownish-piceous, moderately convex, rather strongly shin-

ing; pubescence moderate in length and density, somewhat coarse, dark

fulvous, not conspicuous. Head feebly convex, rather finely punctured, not

very densely so toward the middle; upper lobes of eye very large and con-

spicuous, separated by scarcely four times their width; antenne rather

robust, gradually but unusually feebly incrassate toward apex, third joint

much shorter than the next two. Prothorax fully two-thirds wider than long,

the apex broadly, distinctly emarginate and noticeably narrower than the

base, the latter transverse, the lateral sinuations very wide, feeble but dis-

tinct ; basal angles very slightly obtuse but not in the least rounded; sides

almost evenly but feebly arcuate throughout; disk rather finely, very densely

punctate, the punctures decidedly sparser toward the middle and crowded but

not very coalescent laterally. Scutellum moderate. lytra fully three times

as long as the prothorax and somewhat distinctly wider ; sides feebly arcuate ;

apex somewhat strongly, parabolically rounded; disk with rather coarse but

extremely feebly impressed striae which are somewhat coarsely punctate, the

punctures circular, deep and perforate, generally separated by from one-half

more than to twice their own diameters ; intervals flat, sparsely, rather finely

punctured. Abdomen polished, finely and sparsely punctate, the pubescence

rather long, pale and somewhat conspicuous. Legs not very robust.

greatly exceeding the third in length, the latter strongly emarginate ; inter- -

mediate somewhat feebly but distinctly dilated ; abdomen narrowly and very

distinctly impressed in the middle toward base.

California (Newhall) ; Lower California.

The two representatives of this species do not indicate any great

variability other than that due to sex. The species may be dis-

tinguished from castaneus by its greater convexity, still larger and

very conspicuous eyes, finer, less coalescent punctuation of the

pronotum, more feebly arcuate sides of the latter and several other

less important characters. The hind wings protrude slightly beyond

the elytra in the type.

13 B. pratensis Lec.—Col. of Kans., 1859, p. 15.—Oval, very convex,

black ; legs piceous ; lustre rather dull and alutaceous ; pubescence somewhat

dense, short and very robust, pale fulvo-cinereous and conspicuous. Head

becoming very minute anteriorly and at the sides; epistoma broadly, moder-

ately sinuate; upper lobe of eyes small; antenne rather slender, outer joints

gradually incrassate, third shorter than the next two together. Prothorax but

slightly more than one-half wider than long, rather strongly narrowed from

base to apex; sides evenly and strongly arcuate ; base transverse, moderately

bisinuate; basal angles not rounded ; apex very feebly emarginate in circular

arc; disk very densely, not very coarsely punctate, the punctures tending to

coalesce longitudinally toward the sides, distinctly separated in the middle.

long as the prothorax and, behind the middle, a little wider than the latter,

sides, rather coarsely and very closely punctate, more finely so toward the

suture; intervals finely and rather densely punctured. Abdomen polished,

somewhat coarsely and not very sparsely punctured; pubescence very short,

sparse and inconspicuous. Legs rather slender.

narrowly and feebly impressed in the middle toward base.

Kansas; Colorado; Nebraska; Texas.

The extensive series before me is rather heterogeneous and almost

undoubtedly comprises several distinct varietal forms, the descrip-

tion refers to the typical form from Kansas, which is rather smaller

than those from Colorado and very much smaller than the Texan

representatives. There is a marked divergence, also, in the close-

ness of the strial punctuation, the punctures generally being sepa-

rated by rather less than their own diameters toward the suture,

but in one specimen from Nebraska they are separated by from two

to three times this amount. The pronotal punctuation is very fine

and dense in the Texan forms, with but little tendency to coalescence

laterally. There are apparently no stable characters, however, upon

which to base recognizable species and I therefore leave this subject

for future investigation.

The wings are extremely rudimentary, consisting of a very small

parallel subopaque cellular fillet, devoid of venation, but slightly

more than one-half as long as the prothorax, one-fifth as long as

the elytra, and rather more than twice as long as wide. The elytra

are subconnate,

14 B. oregonensis n. sp.—Oblong-oval, rather strongly convex, aluta-

ceous in lustre, grayish-black; legs dark rufous; pubescence moderate in

length, rather sparse but coarse, pale yellowish-cinereous in.color and very

distinct, easily removable. Head moderately transverse and convex, rather

finely and feebly punctate, the punctures a little coarser and longitudinally

subcoalescent toward the middle of the vertex; upper lobe of eyes moderate,

surrounded except posteriorly by a very deep impressed groove; antenne

moderate, gradually and feebly incrassate toward tip, third joint short, not

twice as long as the second and very much shorter than the next two, joints

three to five uniformly and very rapidly decreasing in length. Prothorax rather

transverse, about three-fourths wider than long, very feebly narrowed from

base to apex; sides almost evenly and rather strongly arcuate in the male,

straighter or even very broadly sinuate toward base, the latter transverse, the

lateral sinuations strong, the basal angles right, not at all rounded and rather

prominent; disk finely, very densely and rather feebly punctured, a little

more sparsely so toward the middle, tending to coalesce longitudinally toward

the sides. Scutellum moderate, ogival. lytra, behind the middle, quite

distinctly wider than the prothorax, scarcely three times as long as the latter ;

sides distinctly arcuate posteriorly ; disk very finely striate, the strie exceed-

but rather strongly impressed throughout in the male, very finely and closely

punctured throughout; intervals usually slightly convex in the male and flat

in the female, very finely and rather sparsely punctate. Abdomen polished,

finely, not densely punctate, the pubescence short and fine, pale and distinct

but not conspicuous. Legs rather slender.

Oregon.

With the typical representatives from Oregon I have associated

two females which, however, probably represent distinct but closely

allied species. One of these from Benicia, California, is much larger

and wider, with rather deeper more even pronotal punctuation, very

dense throughout but not coalescent, the other from southern Idaho,

having the pronotal punctuation quite sparse toward the middle and

rapidly much denser toward the sides; this specimen is also larger

and very convex, with the abdomen dull. In the absence of males

I think it better to leave these species undescribed, and the above

description and measurements apply only to the Oregon specimens,

This species is not closely related to any other, but resembles

substriatus in some of its characters. The wings are rather well

developed, being but slightly shorter than the elytra.

15 B. miger n. sp.—Oblong-elongate, parallel, rather depressed, black ;

legs dark rufo-piceous ; integuments somewhat shining; pubescence Short,

fine, dark piceo-fulvous, rather abundant but very inconspicuous. Head

moderately coarsely and very densely punctate; upper lobe of eyes rather

small; antenne somewhat slender, gradually and moderately incrassate

toward apex, third joint much shorter than the next two, seventh longer than

wide, eighth triangular, as wide as long, tenth slightly wider than long.

Prothorax about two-thirds wider than long, the apex distinctly narrower than

the base; sides evenly and rather strongly arcuate throughout; base trans-

verse, the sinuations feeble but distinct, the basal angles rather broadly

obtuse but generally not appreciably rounded ; apex extremely feebly incur-

vate, the apical angles distinctly and rather broadly rounded; disk rather

coarsely deeply and very densely punctate throughout, the punctures very

coalescent longitudinally toward the sides. Scutellum small. £lytra about

three times as long as the prothorax and equal in width to the latter; sides

more than their own diameters ; intervals flat, very finely, sparsely punctured.

in length, very fine, sparse, dark in color and not at all conspicuous. Legs

somewhat short and robust.

equal; intermediate much more feebly but distinctly dilated ; abdomen with

an elongate-oval feeble impression before the middle, in which the punctuation

is not distinctly denser.

Arizona (Peach Springs).

The wings are moderately developed, rather distinctly hyaline

and iridescent, slender, a little more than three times as long as

wide, distinctly veined, about one-half longer than the prothorax

and nearly three-fourths as long as the elytra.

This species is not closely allied to any other here described and

may be easily recognized by its parallel depressed form, very fine

elytral and coarse abdominal punctuation, and structure of the hind

wings. From rufipes, which it most nearly resembles in size of

the wings, it may be at once separated by its more depressed form,

shorter prothorax, feebler, finer elytral striz and darker legs.

second and very much shorter than the next two together. Prothorar moder-

ately transverse, scarcely two-thirds wider than long, feebly narrowed from

base to apex, the sides evenly and strongly areuate throughout; base trans-

verse, the sinuations rather feeble; basal angles distinctly obtuse and very

narrowly rounded; apex very feebly emarginate in circular arc, the apical

angles narrowly although quite distinctly rounded; disk evenly convex,

coarsely, very deeply and extremely densely punctate throughout, the pune-

transverse. £lytra scarcely three times as long as the prothorax and, behind

the middle, very slightly wider, broadly, parabolically rounded behind ; sides

but deeply and very distinctly punctured, the punctures generally separated

by a little less than twice their own diameters ; intervals very feebly convex,

much more strongly so laterally, very finely and rather sparsely punctate.

slightly more than one-half as wide as the second, the latter about equal in

length and width to the third, the latter broadly emarginate ; intermediate

rather strongly dilated; both pairs densely spongiose beneath; abdomen

rather narrowly and feebly impressed in the middle toward base.

Length % 5.0 mm., 9 5.0-6.0 mm.; width % 1.9-2.1 mm., 9 2.2-2.6 mm.

California (San Diego); Arizona; Texas?

This species belongs to the San Diego fauna, perhaps extending

through to Western Texas; it is represented in the middle coast

regions of California by elongatus, in the high Sierras by inquisitus,

and in the desert regions of the Humboldt Basin by crassicornis.

It is remarkable, in common with pulverulentus, for the unusual

difference in form and size between the male and female, the former

being much the more slender; it is further distinguishable from its

allies by its usually bright rufo-ferruginous legs, duller lustre and

longer, paler and more conspicuous abdominal pubescence.

440 Coleopterological Notices.

The wings are not so rudimentary as in its allies or pulverulentus,

being rather wide, subhyaline, with two strong discal veins; they

are fully one-half longer than the prothorax and two-thirds as long

as the elytra.

19 B. crassicornmis n. sp.—Oblong, the sides nearly parallel, rather

robust, moderately convex, somewhat dull in lustre, black; legs dark rufous ;

pubescence short, rather abundant but dark fulvo-cinereous in color and not

at all conspicuous. Head strongly transverse, feebly convex, deeply punctate,

the punctures very dense, somewhat sparser and coarser toward the middle;

upper lobe of eyes small; epistoma distinctly but moderately sinuate ; antenne

unusually robust, the three last joints much wider and forming a strong loose

club, third joint rather long, nearly as Jong as the next two combined, eighth

distinctly wider than the seventh and wider than long, tenth rather wider

than either the ninth or eleventh. Prothorax rather elongate, scarcely one-

lialf wider than long, the apex but slightly narrower than the base; sides

feebly arcuate, rather more strongly so in the middle and nearly straight

toward base, the latter transverse, the sinuations moderate; basal angles not

at all rounded; disk deeply, moderately coarsely and very densely punctate

throughout, the punctures not decidedly coalescent laterally. Seutellum

moderate, almost confluently punctured. lytra subequal in width to the

prothorax and two and one-half times as long, the sides very feebly areuate,

rather broadly, parabolically rounded behind; disk finely striate, the strie

rather widely feebly impressed, a little more strongly so externaily and near

the suture, very finely, approximately punctate; intervals very slightly

convex, minutely, sparsely punctate. Abdomen shining, finely but not very

sparsely punctate, the pubescence short, very fine, dark brownish in color and

not at all conspicuous. Legs moderately robust.

Male.—Anterior tarsi strongly, the intermediate moderately, dilated, the

second joint of the former longer and also somewhat wider than the third

which is deeply emarginate; both pairs densely spongiose beneath ; abdomen

rather broadly, feebly impressed in the middle toward base, with the pune-

tures narrowly denser along the middle of the first segment.

Length 5.6 mm.; width 2.3-2.4 mm.

Nevada (Reno).

Moderately abundant near the Truckee River. J was at first

inclined to regard this as identical with rufipes, but more careful

study convinced me that they cannot be associated together. The

present species differs in its much finer, shorter abdominal pubes-

cence, rather Jonger legs, in the fact that the male and female are

nearly similar in form and size, and in the form of the wings which

are nearly as in ¢nquisitus, very slender and elongate, although

decidedly Jess than one-half.as long as the elytra.

The antenne are distinctly more robust and, especially, with a

much broader club than in any of the allicd species and the third

joint is more elongate.

20 B. elongatus n. sp.—Elongate-oval, strongly convex, black; legs

piceous-black ; integuments dull; pubescence rather short, sparse, dark

fulvo-cinereous and inconspicuous. Head transverse, feebly convex, rather

finely, deeply, nearly evenly and very densely punctate; epistoma broadly

and unusually feebly sinuate; upper lobe of eyes small; antenue rather

robust, very evenly, gradually but moderately inerassate from the seventh

joint, third short, scarcely twice as long as the second and much shorter than

the next two together, eleventh rather longer than wide, narrowly truncate at

apex and scarcely visibly narrower than the tenth. Prothorax rather elongate,

about two-fifths wider than long, very feebly narrowed from base to apex, the

sides almost evenly and rather feebly arcuate; base transverse, the sinuations

moderate; basal angles rather more than right, not at all rounded; apex

feebly emarginate in circular arc; disk evenly convex, very densely punctate,

the punctures fine toward the middle where they are generally separated by

scarcely their own diameters, a little coarser, very dense and with a slight

tendency to longitudinal coalescence laterally. Scutellam moderate, densely

punctate. Elytra, just behind the middle, slightly wider than the prothorax,

about two and two-thirds times as long as the latter, parabolically and some-

what broadly rounded behind; sides distinctly but broadly arcuate; disk

very finely, feebly striate, the sutural and outer strie very slightly more

distinct, very finely feebly and approximately punctate; intervals nearly

flat, finely and sparsely punctate. Abdomen shining, rather rugulose, finely,

sparsely punctate, the pubescence short, fine, sparse, rather dark and not

conspicuous. Legs rather long and slender.

Male.—Anterior tarsi very strongly dilated, the second joint much longer

than the third; intermediate less strongly dilated ; abdomen broadly and

feebly impressed in the middle toward base; the punctures crowded and dense

only in a small oval area in the anterior half of the basal segment.

Length 5.6 mm.; width 2.2 min.

California (Lake Co.).

The two specimens before me are males, and from their narrow

slender form it is probable that the female will prove to be robust

as in rufipes; they indicate a species rather closely allied to rujfipes,

but differing conspicuously in the nature of the abdominal pubes-

cence, also in the somewhat larger size and longer piceous-black

legs. The antenne are nearly as in rufipes, but are more gradually

incrassate, the three outer joints not being at all abruptly wider as

is the case in that species.

I have not been able to inspect the wings, but they are undoubt-

edly rudimentary.

21 WB. meestus Melsh.—Proc. Ac. Phila., III, p. 65.—Oval, slightly in-

flated behind, rather strongly convex, black, strongly shining; pubescence

fine, short, pale yellowish-cinereous in color, not dense. Head transverse,

feebly convex, very deeply, moderately coarsely and densely punctate, the

punctures abruptly finer along the broadly sinuate epistomal apex; upper

lobe of eyes moderate, rounded; antenne black, robust, gradually incrassate

toward apex, third joint scarcely twice as long as the second, much shorter

than the next two, eleventh wider than long, fully as wide as the tenth.

Prothorax nearly two-thirds wider than long, widest at two-fifths the length

from the base; sides feebly convergent from base to apex, strongly, almost

evenly arcuate, straighter or even feebly subsinuate toward base, the latter

transverse, the lateral sinuations very strong, the basal angles slightly acute,

not in the least rounded and rather prominent; apex broadly emarginate in

circular arc, the angles not at all prominent and very narrowly rounded; disk

very deeply and perforately punctate, the punctures finer and sparse toward

the middle, coarser and denser but not at all contiguous or confluent toward

the sides, usually abruptly very fine and sparse along the acute marginal

bead, especially toward the base. Scutellum moderate, very finely punctate.

Elytra with the sides very distinctly arcuate, especially behind the middle

where they are distinctly wider than the prothorax, parabolically rounded at

apex and about two and one-half times as long as the prothorax ; disk with

very fine feebly impressed strie toward the suture, which become rapidly

much coarser and more deeply impressed laterally; strie finely punctate,

more coarsely so laterally; punctures elongate and posteriorly evanescent,

generally separated by twice their own widths; intervals very finely, some-

what sparsely punctured. Abdomen polished, finely, rather sparsely punctate,

very sparsely clothed with short inconspicuous pubescence. Legs rather short,

the tarsi long.

Male.—Anterior tarsi strongly dilated, the basal joint much wider than long

and distinctly narrower than the second and third, the latter short, subequal,

transversely crescentiform ; middle tarsi very distinctly dilated, compact,

the three basal joints equal in width; both pairs densely spongy-pubescent

beneath ; abdomen not distinctly modified.

Length 4.7-5.4 mm.; width 2.1—2.4 mm.

New Hampshire; Rhode Island; Virginia.

This, the only eastern species of the ordinary type, may be easily

identified by its intense black color, shining, rather sparsely pune-

tate integuments and prominent basal angles of the prothorax, as

well as several other characters. The wings are not well developed,

consisting of a long slender byaline fillet, nearly one-half longer

than the prothorax and three-fifths as long as the elytra.

22 B. gregalis n. sp.—Oblong-oval, moderately convex, black; antenne

piceous-black ; legs dark rufo-piceous ; integuments polished ; pubescence fine,

rather short and sparse, pale fulyo-cinereous and not conspicuous. J/ead

about two-fifths wider than long, not very coarsely but deeply punctate, the

punctures rather elongate, distinctly separated transversely, but tending to

coalesce longitudinally ; epistoma broadly sinuate ; upper lobe of eyes mode-

rate or rather small, rounded ; antenne moderate, gradually incrassate toward

apex, third joint about three-fourths longer than the second, much shorter

than the next two together, eleventh as long as wide, truncate, rather dis-

tinctly wider than the ninth. Prothorax about three-fourths wider than long ;

sides feebly convergent from base to apex, moderately and very evenly arcuate

throughout ; base transverse, the lateral sinuations moderately distinct, the

basal angles very slightly obtuse, not rounded but not prominent; apex

broadly, evenly emarginate in circular arc; disk rather densely punctate, the

punctures deep, moderate in size, somewhat elongate, not much sparser toward

the middle, tending slightly to coalesce longitudinally throughout the disk,

but distinctly separated transversely. Scutellum moderate. Elytra rather

less than three times as long as, and, behind the middle, a little wider than,

the prothorax ; sides distinctly arcuate posteriorly, together evenly rounded

at apex; disk finely striate, the strize feebly impressed, not appreciably more

deeply so toward the sides, finely punctured, the punctures feeble and gener-

ally separated by from one-half more than to twice their own diameters ;

intervals nearly fiat, from four to five times as wide as the strial punctures,

very finely and sparsely punctured. Abdomen polished, very finely and some-

what sparsely punctate, the pubescence rather long, moderately dense and

distinct. Legs and tarsi moderate.

Male.—Anterior tarsi strongly dilated, the basal joint slightly wider than

long, narrower than the second and third, the latter equal in width, trans-

verse, the apex broadly sinuate toward the middle; intermediate rather feebly

dilated ; both pairs densely spongy-pubescent beneath ; abdomen broadly and

more or less feebly impressed in the middle toward base.

Length 3.84.6 mm.; width 1.6-2.0 mm.

Washington State; California (Placer Co. and Lake Tahoe);

Wyoming (Laramie); Colorado (Veta Pass).

The specimens from Lake Tahoe are rather smaller and narrower

than the others, with the punctuation of the pronotum tending to

become finer and sparser toward the middle, while those from

Wyoming have the entire surface of this part almost longitudinally

rugulose; the typical forms are from Washington State. The series

before me is very extensive, and the extreme forms do not present

any tangible specific characters

This species somewhat resembles pulverulentus, but may be

distinguished at once by its smaller size, more depressed form and

more developed wings. The latter in the present species are rela-

tively a little longer than in mestus, and broader, hyaline, about

four-fifths longer than the prothorax and nearly five-sixths as long

as the elytra.

23 B. substriatus Champ.—Biol. Cent.-Amer. Col., IV, Pt. 2, p. 128;

anthracinus Sturm, i. litt.

I have applied this name to a series which, in general, very rea-

sonably satisfies the description above cited. The specimens are

from Montana, Wyoming, Colorado and New Mexico, being con-

fined to the more elevated regions of the Rocky Mountains. The

species is black throughout, rather robust, oblong, moderately con-

vex, distinctly shining and with the sides nearly parallel. The

strie of the elytra are exceedingly feebly impressed, very finely,

rather closely punctured and, in some of the specimens, almost con-

fused toward base with the somewhat unusually coarse punctures

of the flat intervals. The anterior tarsi of the male are strongly

dilated, the intermediate very distinctly, although less strongly so,

and the wings are well developed, being fully as long as the elytra.

The punctures of the pronotum are rather coarse, decidedly elon-

gate, closely crowded but not greatly coalescent laterally, and

usually very slightly sparser toward the middle in the female, and

more decidedly so in the male. The latter sex resembles the female in

form but is rather smaller. Length 5.0-5.5 mm.; width 2.1—2.6 mm.

24 B. lepidus n. sp.—Narrow, elongate-oval, moderately convex, gradu-

ally narrowed behind from near the middle of the elytra, black, moderately

shining or subalutaceous ; pubescence moderate in length, fine, rather sparse,

dark piceo-cinereous and not conspicuous. /ead fully one-half wider than

long, finely, rather densely punctate; upper lobe of eyes moderate, rounded ;

antenne rather slender, the last three joints somewhat abruptly wider, third

one-half longer than the second and a little longer than the fourth, eleventh

somewhat pointed and a little narrower than the tenth. Prothorax about two-

thirds wider than long, the sides very feebly convergent from base to apex,

feebly arcuate anteriorly, broadly and extremely feebly sinuate in the basal

half; base transverse, the lateral sinuations strong; basal angles right, not

in the least rounded; apex broadly emarginate in circular arc; disk finely

punctate, the punctures equal in size throughout, separated by abeut twice

their diameters toward the middle and rather denser laterally, but without

any marked tendency to coalesce. Scutellum moderate, ogival, rather dis-

tinctly wider than long. £/ytra about two and one-half times as long as the

prothorax, subequal in width to the latter, the sides parallel toward base and

scarcely visibly arcuate; disk very finely striate, the strize feebly impressed,

not becoming stronger laterally, very finely punctate throughout the width,

the punctures generally separated by two or three times their own diameters ;

intervals nearly flat, very finely, rather sparsely and unusually feebly punc-

tate. Abdomen polished, very finely and sparsely punctate, the pubescence

short, cinereous, distinct but not conspicuous. Leys well developed; tarsi

slender.

Coleopterological Notices. 445

Male.—Anterior tarsi moderately strongly dilated, second and third joints

subequal, the latter strongly angularly emarginate in the middle of its dorsal

apex ; intermediate slender, scarcely perceptibly dilated ; both pairs spongiose

beneath ; abdomen narrowly and feebly flattened in the middle toward base,

the punctures rather abruptly very dense in a large median area of the basal

segment, and less conspicuously so on the second segment, fifth with a deep

rounded, impressed fovea.

Length 3.9-4.2 mm.; width 1.6-1.8 mm.

Texas.

A small narrow species, allied by the formation of the sides of

the prothorax in the neighborhood of the basal angles, to mestus,

but abundantly distinct in its narrower form, less convexity, finer

pronotal punctures and, especially, by the finer punctures of the

elytral strie, these not becoming more strongly impressed laterally.

It is still more widely separated because of the notably more feeble

dilatation of the anterior tarsi of the male and its more slender

antenne.

25 B. equalis n.sp.—Elongate-oval, narrow, strongly convex, alutaceous

in lustre, black ; pubescence fine, rather sparse, moderate in length, dark fulvo-

cinereous in color and not very conspicuous. Head moderately transverse and

convex, somewhat finely and densely punctate, the punctures tending to coal-

esce longitudinally ; upper lobe of eyes moderate, rounded ; epistoma broadly,

distinctly sinuate; antenne rather slender, gradually incrassate through the

last four joints, third not quite twice as long as the second and much shorter

than the next two, eleventh scarcely as wide as the tenth, the sensitive ter-

minal pubescence unusually fine. Prothorar about three-fifths wider than

long ; sides feebly convergent from base to apex, rather feebly and very evenly

arcuate throughout; base transverse, the lateral sinuations distinct; basal

angles very slightly obtuse, not prominent but not distinctly rounded ; apex

broadly emarginate in circular arc; disk moderately coarsely, densely punc-

tate, the punctures tending slightly to coalesce longitudinally, rather sparser

toward the middle and decidedly finer, but denser toward the sides. Scutellum

moderate, ogival. Elytra about equal in width to the prothorax and between

two and one-half and three times longer, rather acutely and parabolically

rounded at apex ; sides parallel and just visibly arcuate; disk finely striate,

the strie rather feebly impressed throughout the width but distinct, finely,

evenly and approximately punctured, the punctures distant generally by

about their own diameters; intervals nearly flat, very much more finely but

not very densely punctate. Abdomen rather finely and densely punctate, more

shining, the pubescence rather distinct. Legs well developed.

Male.—Anterior tarsi strongly dilated, the second and third joints subequal

in length and width; intermediate feebly but very distinctly dilated, with the

second joint rather wider than either the first or third; both pairs with dense

spongiose pads beneath ; abdomen rather narrowly and strongly impressed in

basal segment, fifth segment with a small strong rounded impression.

Length 4.5 mm. ;- width 1.9 mm.

California (San Bernardino).

This species resembles gregalis but differs in its more convex

form, duller lustre, much more approximately punctate elytral

strie, notably denser abdominal punctuation, stronger basal im-

pression of the abdomen in the male and, especially, in the structure

of the anterior tarsi of that sex. In gregalis the third joint is dis-

tinctly shorter than the second, while in zqualis the second joint is

not only longer than in gregalis, but is not conspicuously longer

than the third.

In equalis, contrary to the general rule, the pronotal punctures

become rather finer laterally.

The type is unique. There are two specimens before me from

Utah which indicate a closely allied but distinct species.

26 B. fumebris n. sp.—Oblong-oval, moderately convex, black; legs

dark rufo-piceous ; integuments rather strongly shining; pubescence short,

coarse, very sparse, easily removable, pale fulvous in color and distinct.

Head transverse, feebly convex, rather finely and densely punctate; upper

lobe of eyes small; antennz not very robust, the three outer joints somewhat

abruptly but not greatly dilated, third joint much shorter than the next two,

eleventh much narrower than the tenth. Prothorar about one-half wider than

long, feebly narrowed from base to apex; sides feebly arcuate, straight or very

feebly, broadly sinuate toward base, the latter transverse, with moderate sinua-

tions; basal angles right, not at all rounded; apex feebly emarginate in

circular arc; disk evenly convex, rather finely, moderately densely punctate

toward the middle where the punctures,are generally separated by distinctly

more than their own diameters, distinctly larger and very dense near the sides

but with slight tendency to longitudinal coalescence. Scutellum rather large,

transversely ogival, finely, rather densely punctate. lytra scarcely wider

than the prothorax and uearly three times as long, rather broadly, paraboli-

cally rounded behind; sides feebly arcuate, rather more distinctly so behind ;

disk with very fine stria# which are extremely feebly impressed and very finely,

rather approximately punctured, rather more strongly impressed and very

slightly more coarsely punctate externally ; intervals flat toward the suture,

more convex laterally, finely, sparsely punctate. Abdomen shining, finely,

sparsely punctured and with coarse, sparse, pale flavo-cinereous pubescence,

moderate in length and quite conspicuous. Legs rather long.

Male.—Unknown.

could only be confounded with rufipes, from which it differs in its

much more shining surface, more oblong and less convex form,

greater size, much more feebly impressed elytral strie, and especi-

ally in its much sparser and less persistent, shorter, coarser and

paler elytral pubescence. The abdominal pubescence is nearly as

in rufipes, but is a little shorter.

27 B. pulverulentus Mann.—Bull. Mosc., 1848, II, p. 276.—Hlongate-

oval, strongly convex, black throughout, polished; pubescence dark fusco-

cinereous in color, rather long but sparse and inconspicuous. Head much

wider than long, feebly convex, somewhat strongly and densely punctate, the

punctures sometimes a little sparser along the middle, not confluent; upper

lobe of eyes moderate, rounded ; antenne rather robust, gradually and moder-

ately incrassate through the last four joints, third scarcely twice as long as

the second but distinctly longer than the third, eleventh fully as long as wide,

narrowly truncate at apex, as wide as the tenth. Prothorax rather elongate,

scarcely more than one-half wider than long; sides very feebly convergent

from base to apex, feebly arcuate, straight or extremely feebly sinuate toward

base, the latter transverse, the lateral sinuations distinct ; basal angles very

slightly obtuse, not in the least rounded; apex feebly emarginate in circular

arc; disk sometimes slightly flattened or subexplanate toward the basal angles,

somewhat coarsely and densely punctate, the punctures rather unevenly dis-

tributed but usually separated by nearly twice their diameters toward the

middle, denser but not distinctly coalescent toward the sides. Scutellum

small, ogival. Elytra about two and one-half times as long as the prothorax,

scarcely perceptibly wider than the latter, rather acutely parabolic at apex ;

sides parallel and rather distinctly arcuate; disk with rather fine strie which

are somewhat distinctly and broadly impressed, not much more strongly so

externally but usually more distinctly so near the suture, the striz with fine

but deep punctures, generally separated by one-half more than their own

diameters ; intervals very feebly convex, somewhat coarsely and very sparsely

punctate. Abdomen finely, sparsely punctate, the pubescence distinct but

short and sparse, dark fusco-cinereous and not conspicuous. Legs moderate.

Male.—Anterior tarsi very strongly dilated, the third joint distinctly shorter

than the second and strongly, angularly emarginate; intermediate rather

strongly dilated, the second joint notably wider than the first and a little

wider than the third; both pairs densely spongiose beneath ; abdomen rather

narrowly and distinctly impressed in the middle toward base, the punctures

not distinctly denser in the middle of the basal segment, fifth segment with a

feeble oval impression ; body notably more slender than in the female.

California (Mendocino, San Francisco, and Monterey).

This is the commonest species about San Francisco, and in fact

is the only one which exists in that locality to any great extent;

it is usually confounded in our cabinets with several other species

here described, and especially rufipes, which is more southern in

habitat. It may be easily distinguished from those to which it is

more closely allied by its polished surface—pruinose when living,—

the rather coarser and more distinct punctures of the intervals,

and by the form and size of the wings which consist of a slender

subopaque cellulo-membranous fillet, without noticeable venation,

slightly wider in apical half, about four-fifths as long as the pro-

thorax and less than one-third as long as the elytra. The male is

decidedly smaller and, especially, more slender than the female.

Pulverulentus is distinctly smaller than rufipes and as these

species are both abundant, the differences may be rendered very

obvious if the large series possessed by almost every cabinet of note

be properly separated.

28 B. parallelus n. sp.—Elongate-oval, subparallel, strongly convex,

rather strongly shining, black; legs piceo-rufous ; pubescence fine, moderate

in length, sparse, dark piceo-fulvous and very inconspicuous. Head moder-

ately transverse, feebly convex, densely and deeply punctate; upper lobe of

eyes small; antenne rather robust, the last three joints rather abruptly but

slightly wider, third joint much shorter than the next two together. Prothorax

but slightly more than one-half wider than long, very feebly narrowed from

base to apex, the sides evenly and rather strongly arcuate; basal sinuations

moderate; basal angles right, not in the least rounded; disk evenly convex,

very densely but not very confluently punctate toward the sides, much more

sparsely so toward the middle especially near the base; punctures moderate

in size. Scutellum ogival, rather finely and densely punctate, with the usual

impunctate polished margin. Llytra nearly three times as long as the protho-

rax, rather shorter in the male, subequal in width throughout to the latter,

narrowly, parabolically rounded at apex; disk with rows of very fine pune-

tures, the striz# extremely feebly impressed, more visibly so toward the suture

but scarcely toward the sides, the punctures separated by from two to three

times their own diameters ; intervals flat, finely and very sparsely punctured.

Abdomen finely, sparsely punctate, with short sparse inconspicuous pubescence ;

surface generally more or less longitudinally rugulose. Legs moderate.

Male.—Anterior tarsi very strongly dilated, the second joint much longer

than the third; intermediate rather strongly dilated but much less so than

the anterior; abdomen broadly, moderately impressed in the middle toward

base, the fifth segment with a small transversely-oval and rather strongly

impressed apical fovea.

California (Mountains of Santa Cruz Co.). Mr. Harford.

This species is closely allied to pulverulentus, but differs in

several points to such a degree that I can see no other correct

course to pursue than to separate it. The form is rather narrower

Coleopterological Notices. 449

and more parallel, and the elytral striz more finely punctured and

‘more feebly impressed. The males and females are of similar form

and nearly equal in size, and the wings consist of an exceedingly

slender elongate parallel fillet, rather membranous in texture, devoid

of distinct venation, more than four times as long as wide, about

one-fourth longer than the protborax and nearly one-half as long as

the elytra, with a deep sinuation on the lower edge near the apex.

This singular form is constant in the only two specimens dissected.

It will be seen, therefore, that the wings are very different from

those of pulverulentus, but approach those of inguisitus, from which

parallelus differs in its longer prothorax, finer punctures of the

elytral strie and decidedly greater convexity.

29 B. imquisitus n. sp.—Oblong-oval, moderately convex, strongly

shining, black above and beneath; legs dark piceo-rufous ; pubescence fine,

short, very sparse, dark piceo-cinereous and inconspicuous. Head moderate,

fully one-half wider than long, feebly convex, deeply, not very coarsely,

densely punctate, the punctures decidedly sparser along the middle; epistoma

moderately sinuate; upper lobe of eyes small, rounded; antenne somewhat

robust, the last three joints rather abruptly but slightly wider, third joint

twice as long as the second, the latter shorter than the fifth, three to five

uniformly and rapidly Gecreasing in length, eighth a little wider, as long as

wide, eleventh very slightly narrower than the tenth. Prothorar one-half

wider than long, sides very feebly convergent from base to apex, evenly and

rather feebly arcuate; base transverse, the sinuations moderately distinct ;

basal angles right, not at all rounded; apex broadly, feebly emarginate in

circular arc; disk somewhat finely, densely punctate, more sparsely so toward

the middle where the punctures are generally separated by one-half more than

their own diameters, not coalescent laterally. Scutellum moderate, densely,

finely punctate, the posterior edge broadly polished and impunctate. Elytra

subequal in width to the prothorax and about two and one-half times as long ;

sides very feebly arcuate, parabolically rounded at apex; disk distinctly flat-

tened toward the suture, finely striate, the strie feebly but rather abruptly

impressed, very slightly deeper and more coarsely punctate laterally ; strial

punctures generally fine and very approximate, usually separated by between

once and twice their own diameters; intervals flat, finely and sparsely punc-

tured. Abdomen polished, finely, sparsely punctate, the pubescence very sparse,

rather short, fine, dark fulvo-cinereous and not conspicuous. Legs moderately

robust.

Male.—Anterior tarsi very strongly dilated, the second joint decidedly

longer than the third; intermediate distinctly but not strongly dilated, the

second joint a little wider than the first and third; abdomen narrowly and

rather strongly impressed in the middle toward base, the punctuation not

distinctly denser in the middle of the first segment.

Length 5.0 mm.; width 2.0 mm.

California (Truckee, Nevada Co.).

The three specimens before me indicate a species allied to pul-

verulentus, but quite distinet in its more depressed parallel form,

similarity in size and form of the male and female, and more

decidedly in the form of the hind wings. The wings are about one-

fourth longer than the prothorax and one-half as long as the elytra,

consisting of a long parallel very slender fillet, subhyaline in struc-

ture, about four times as long as wide, with the two veins very

feebly developed, not extending quite to the middle and equally tri-

secting the width throughout their extent.

30 B. auripilis Horn.—Trans. Am. Phil. Soe., XIV, p. 353.—Oblong-

oval, very convex; sides parallel; integuments dull, dark brown in color ;

pubescence moderate in length, recumbent, rather robust and dense, bright

golden-yellow and blackish-piceous confusedly intermingled, the two kinds

subequal in size and abundance. Head moderate, strongly transverse ; sides

strongly convergent anteriorly from before the eyes, the apex strongly sinuate ;

surface feebly convex, very densely punctate, the punctures coarse posteriorly,

finer anteriorly ; interspaces rather shining, convex, very minutely, evenly

reticulate ; eyes moderate ; antennz rather short and slender, gradually and

not very strongly incrassate toward apex, second joint not one-half as long as

the third, the latter rather elongate although distinctly shorter than the next

two combined. Prothorax feebly narrowed from base to apex, three-fourths

wider than long; sides slightly more strongly arcuate before the middle ; apex

broadly emarginate ; base transverse, the lateral sinuations broad and distinct :

disk very strongly convex, not very coarsely but deeply evenly and very

densely punctate throughout, the punctures nearly in mutual contact laterally,

but not coalescent; interspaces convex, alutaceous, very minutely, evenly

the female.

It is interesting to note that the hairs growing from the punc-

tures of the elytral strie, which are usually extremely minute, here

become quite long and distinct; this may possibly be dependent in

some way upon the slight difference between these punctures and

those of the intervals observable in this species.

This is a very distinct species in its elongate subcylindrical,

although but moderately convex form and pale coloration. It

differs from hesperius in its much shorter pubescence, longer pro-

thorax, much more shining and more sparsely punctate abdomen

and very much larger eyes. From intermiaxtus, with which it may

also be confused, it differs in its less transverse prothorax, more

shining integuments, and finer and feebler elytral strive, as well as

in the uniform pubescence.

Although represented by the female only, I have placed the present

species as well as hesperius and auripilis in the group with feebly

dilated anterior male tarsi, because of their analogy to inftermixtus

in general habitus.

This form is closely allied to veslitus, and in a purely natural

sequence of the species the two must be associated together. It

differs from vestitus in its much longer, finer pubescence and more

strongly dilated anterior tarsi of the male, although even here the

peculiar structure of the tarsus,—the second joint being distinctly

narrower than the third,—is common to them both.

The punctuation of the pronotum varies considerably, and in the

female from Garland is finer, not so dense toward the sides and

without any marked tendency to coalescence. The punctures of the

elytral strive are finer than in any other species known to me, being

decidedly smaller and more feeble than in vestztus.

Arizona—Mr. Morrison.

This species somewhat resembles rufipes in its dull, densely and

finely punctate integuments and dark pubescence, but differs in its

shorter form and smaller size, and, more radically, in the very feeble

dilatation of the male tarsi and more rudimentary hind wings, the

latter in the present species consisting of a slender cellulo-membra-

nous plate, about three and one-half times as long as wide, and

about as long as the prothorax.

The wmbrosus of Champion (Biol. Cent.-Amer. Col., IV, i, Oct.

1885, p. 127) is possibly the same as pimalis, although the length

given for umbrosus is substantially greater than in any of the seven

representatives of pimalis which I have before me, and the punc-

tures of the elytral striz in the latter do not exhibit the slightest

trace of transversality.

The description is taken from the male, the female being a little

more elongate, with the elytra slightly longer. It is a very well-

marked species, forming an easy transition from the ordinary types

of the genus to sulcatus and hydropicus, possessing the elongate

third antennal joint of the latter, with the normal structure of the

head. The punctures of the elytra have nearly the same coarse

perforate appearance as in sulcatus, but are scarcely more than one-

half as large, the strive being much more feebly impressed and the

intervals much wider.

minute slender hair from its anterior wall. Abdomen shining, rather sparsely,

coarsely punctate and finely, sparsely pubescent. Hind wings rather well

developed, a little shorter than the elytra.

California; Texas.

A conspicuous species, distinguishable at once by its deeply

erooved elytra, pale robust and squamiform pubescence, narrowly

subreflexo-explanate sides of the prothorax and polygonal head,

with prominent angulate sides. Together with the next it consti-

tutes a group, comparatively isolated not only by these characters,

but by the very short second and greatly developed third joint of

the antenne.

broadly, feebly arcuate, feebly sinuate laterally; basal angles acute and a

little less posteriorly prominent than the middle; apex truncate between the

slightly advanced acute angles; disk widest slightly behind the middle,

transversely convex, very abruptly and conspicuously, although somewhat

narrowly explanate along the sides, punctured like the head. Scutellum

wide, rather inflated behind, three times as long as, and distinctly wider than,

the prothorax, having deep abrupt deeply punctate grooves, the punctures of

the grooves separated by nearly their own diameters: intervals flat, scabrous,

asperately punctate, and distinctly wider than the grooves, the erect scales

numerous, unevenly arranged. Abdomen finely granulose and but feebly shin-

ing, rather coarsely and densely punctate, somewhat densely covered with

robust recumbent yellowish-cinereous hairs which are conspicuous.

Although allied to sulcatus this species is very easily separated

by its much more robust form, more transverse prothorax, wider

elytral intervals, shorter darker’ more erect and much less conspicu-

ous vestiture of the upper surface and more robust denser and more

distinct pubescence of the abdomen, the latter being duller and more

densely punctate. The explanate lateral portion of the pronotum

is much wider in the present species and almost perfectly flat.

44 B. discolor Horn.—Trans. Am. Phil. Soc., XIV, p. 354.

I have not seen the unique type of this species, but from the

description it would appear as if it were not correctly placed in

Blapstinus. Its coloration is absolutely foreign to this genus,

although quite common in the apterous genera allied to Conibius ;

its glabrous surface is also a very exceptional character especially

among the Californian species of Blapstinus. It is probable that

discolor is apterous, and that it will prove to be a member either

of Conibius or of an allied genus.

MECWS™MUS Horn.

The species of this genus are not very numerous and somewhat

resemble the more elongate and depressed forms of Blapstinus such

as longulus, but on closer observation it is readily seen that the

antenne are rather more slender, the base of the prothorax straight,

the humeri exposed and the hypomera not impressed near the

lateral edges.

The anterior tarsi of the male are moderately dilated and vary

considerably in the vestiture of the under surface, thus affording

excellent subordinate structural characters for the identification of

the species. The wings are well developed, and the flight is proba-

bly stronger than in Blapstinus on account of the greater lightness

of the body.

The species may be divided into two distinct groups as indicated

The largest and most robust species which I have examined, quite

distinct from angustus in the broad prothorax, strongly emarginate

at apex, by the finer strial punctures and coarser punctures of the

Southern California; Arizona (Yuma).

The female does not differ greatly from the male. I have before

me a male example which is entirely rufo-ferruginous in color and

rather more robust, in which the anterior tarsi are scarcely percep-

tibly dilated and clothed beneath with long coarse spines without

trace of squamules; the abdomen being broadly and feebly impressed

in the middle toward base, shows that there can be no mistake

regarding the sex of this specimen, which represents therefore a

closely allied species which should not be named at present, for

without additional specimens I am unable to state whether or not

the peculiar pale color is due to immaturity.

M. temuis n. sp.—Slender, parallel, depressed, piceous-black ; head and

prothorax very slightly paler, rufo-piceous ; integuments shining ; pubescence

Texas (El Paso). Mr. Dunn.

Apparently abundant, and, although allied to parvulus, easily

distinguishable from that species, in addition to the characters here

tofore noted, by the punctuation of the sutural interval which in

advena is generally confused; in parvulus there is a very regular

single row of punctures similar to those of the other intervals.

CONIBIUS Lec.

This genus is quite composite, and as here considered, embraces

five distinct typical forms, represented by seriatus, opacus, sulcatus,

gagates and granulatus, but as far as structural characters of value

are concerned, the groups may be limited to three. These groups

agree among themselves in all the characters before given in the

table of genera, but might possibly be considered of subgeneric

value; at any rate, the difference in general habitus is quite remark-

able. As far as variety of type is concerned, Conibius may be

considered the Asida of the Blapstini.

The sexual characters are generally very slight, the tarsi being

absolutely undilated in the male, but in a few species the anterior

tibie are modified in that sex as described below. As a curious

coincidence, it should be mentioned that similar tibial modifications

are described by Champion as affecting some of the Central Ameri-

can species of Blapstinus, such as ¢¢ébialis and grandis; I have not

observed this character in any of our species however.

California (San Diego).

This appears to be quite a local species, and I have not seen it

from any other locality than that indicated above. It is easily

known by its slender parallel form.

In both parallelus and seriatus the sexual differences are almost

completely obsolete, the males, represented by certain slightly less

robust specimens, seem however to have the abdomen extremely

feebly flattened in the middle toward base. The anterior tibie and

tarsi are not modified in the male; they are short and robust, the

latter very compact.

C. seriatus Lec.—Ann. Lyc. N. Y., V, p. 146.—Oblong, parallel, rather

California (Humboldt and San Bernardino Cos.).

Easily distinguishable from any other species by its coloration

and rather robust form; from guadalupensis, which it approaches,

it is to be known at once by its coloration, decidedly smaller size

and different antennal structure. It is the only species which I

have seen which extends its range from the Arizona faunal regions,

along the Californian sea-coast to the northern limits of the state.

C. guadalupensis np. sp.—Oblong, parallel, rather robust, strongly

convex, piceous-black throughout, the legs and antenne dark rufo-testaceous,

the apex; epistoma distinctly sinuate ; upper lobe of eye very small; antennz

moderately robust, much shorter than the head and prothorax, rather strongly

incrassate toward tip, third joint fully twice as long as wide and but slightly

shorter than the next two together, eleventh scarcely visibly narrower than

the tenth, the latter one-half wider than long. Prothorax two-fifths wider than

fhe head and two-fifths wider than long; base feebly arcuate except near the

sides, fully as wide as the apex which is transversely truncate ; basal sinua-

tions almost obsolete, the angles obtuse but not distinctly rounded and not in

the least produced; sides feebly arcuate, straight toward base; disk widest

rather before the middle, rather finely, deeply and very densely punctate |

throughout, the punctures equal in size although just perceptibly sparser

toward the middle, not at all muricate. Elytra behind the middle scarcely

perceptibly wider than the prothorax and but little more than twice as long ;

sides rather distinctly arcuate; apex obtusely rounded; disk with feebly im-

pressed rows of very small, feeble and rather closely placed punctures, which

become more distinct toward base; intervals minutely and rather sparsely

punctate. Abdomen polished, very finely and sparsely punctured.

Male.—Without distinct sexual modification.

The ample series of eleven specimens which I have before me,

enables me to state with confidence that guadalupensis is quite

distinct from seriatus, with which it bas been confounded by Dr.

Horn (Trans. Am. Ent. Soc., V, 1876, p. 199). The size is con-

stantly very much greater, and it differs otherwise in its more elon-

Head strongly transverse, rather coarsely and confluently punctured behind,

the punctures becoming very fine and dense anteriorly; epistoma rather

strongly sinuate in the middle; upper lobe of eye small, broadly oval;

antenne very robust and compact, nearly as in seriatus, but with the third

joint a little longer. Prothorax moderately transverse, scarcely one-third wider

than long; base truncate equal in width to the apex, the latter extremely

feebly emarginate; basal angles very slightly obtuse, not at all rounded and

slightly produced posteriorly ; sides feebly arcuate anteriorly, straight toward

base; disk widest before the middle, finely and somewhat sparsely punctate,

the punctures becoming much coarser, deeper and very dense toward the sides.

Elytra distinctly wider than the prothorax and scarcely more than twice as

long; sides rather strongly arcuate; humeri obtusely rounded; apex evenly,

not very broadly rounded ; disk with rather feebly impressed strie of small

but distinct and very closely placed punctures, becoming larger toward base;

intervals flat, sparsely and very finely punctured. Abdomen polished, finely

and sparsely but deeply and distinctly punctate.

Male.—Abdomen narrowly and distinctly impressed in the middle toward

base.

Length 3.7-4.5 mm.; width 1.5-1.8 mm.

Arizona.

Although somewhat allied to seriatus, this species may be dis-

tinguished by its oval elytra, wider than the prothorax, by the much

larger and stronger strial punctures, and by the less transverse pro-

thorax with differently formed basal angles.

C. opacus Lec.—WNotibius opac.: New Spec. Col., 1866, p. 118.—Ovate,

strongly convex, black; legs and antenne piceous; lustre extremely dull

because of a fine, strong, granular reticulation ; vestiture as in seriatus. Head

transverse, flat, rather finely, very densely punctate, the punctures longitu-

dinally coalescent posteriorly, finer and muricate anteriorly ; epistoma very

deeply sinuate in the middle; upper lobe of eye small, but larger than usual

and broadly oval; antenne rather long and robust, as long as the head and

prothorax, last three joints forming a strong club, third long, fully as long as

the next two, tenth nearly twice as wide as long, the eleventh much narrower.

Prothorax scarcely one-third wider than the head and one-fourth wider than

long, the apex broadly emarginate, fully as wide as the base which is just

perceptibly and evenly arcuate throughout, the sinuations obsolete; basal

angles not rounded, not prolonged posteriorly but rendered very slightly

prominent from a very feeble gradual sinuation of the sides before them ; sides

anteriorly evenly, rather feebly arcuate; disk widest before the middle very

feebly but somewhat broadly reflexed laterally, rather finely, extremely

densely punctate throughout, the punctures forming long longitudinal ruge,

less marked and finer toward the middle. Jytra oval and subinflated, widest

in the middle, at base feebly emarginate and coarctate throughout with the

prothorax, two-fifths wider than the latter and more than twice as long, rather

acutely rounded at apex; disk very finely but evenly and distinctly striate,

the strie extremely finely punctate, the punctures rather approximate and not

larger toward base; intervals nearly flat toward base, strongly evenly convex

posteriorly, very minutely and somewhat densely punctate. Abdomen shining,

very finely, somewhat sparsely punctate. Jegs long and rather slender.

Male.—Sexual characters not determined.

Length 4.6 mm.; width 2.0 mm.

Lower California (Cape San Lucas). Cab. LeConte.

A very distinct species which could not possibly be confounded

with any other, its rather inflated elytra, dull, densely punctate

integuments and long antenne at once distinguishing it; the epi-

pleure are relatively very wide, resembling somewhat those of

gagates. The bases of the prothorax and elytra are exactiy equal

in width, the humeri not exposed.

The unique type is probably a male, but exhibits no decided

sexual modification.

It is highly probable that the Arizona specimens, hitherto referred

to this species, have been incorrectly identified.

Cc. sulcatus Lec.—Notibius sule.: Aun. Lye. N. Y., V, p. 145.—Oblong-

oval, strongly convex, moderately shining, black; legs and antenne rufous ;

vestiture as in seriatus, but with the sete still more infinitesimal. Head

moderately transverse, the sides near the eyes parallel and straight ; epistoma

broadly, deeply sinuate; surface nearly flat, finely, very densely punctate ;

pact, moderately incrassate toward apex and much shorter than the head and

Coleopterological Notices. 473

Male.—Anterior tibie slender, the anterior surface polished, very finely,

sparsely punctate, strongly and obtusely toothed within at one-third the

length from the base, the portion thence to the base one-half as wide as the

remaining portion.

Length 4.8-5.3 mm.; width 2.0-2.4 mm.

California (San Diego).

The male is more slender than the female. The base of the elytra

being distinctly narrower than the base of the prothorax, together

with the deeply suleate elytra and equally convex intervals, will

render the identification of this species at all times a very easy

matter.

C. alternatus n. sp.—Oblong-oval, very convex, parallel, moderately

shining, black; legs dark rufous; vestiture as in sulcatus, very brittle and

easily removable. Head nearly as in sulcatus, but more coarsely and con-

fluently punctate. Prothorax four-fifths wider than the head and two-thirds

wider than long; base much wider than the apex, broadly arcuate in the

middle, feebly sinuate laterally, the basal angles right, very narrowly rounded

and scarcely extending as far posteriorly as the median portion; apex very

feebly emarginate; sides evenly and rather strongly arcuate; disk widest in

the middle, very feebly explanate posteriorly but not perceptibly so anteriorly,.

somewhat finely and extremely densely punctate, the punctures tending to

coalesce in short irregular ruge toward the sides, finer and not so coalescent

toward the middle. Elytra at base as wide as the base of the prothorax,

behind the middle very slightly wider than the disk of the latter and two and

one-half times as long; sides feebly but distinctly arcuate; disk with deep,

widely impressed sulcations which are somewhat finely and closely but ex-

tremely feebly punctured ; intervals very convex, alternately narrow, moderate

in elevation and as wide as the sulci, and wide and very strongly elevated,

very finely and somewhat densely punctured throughout. Abdomen very finely

punctate, the punctures sparse laterally, denser toward the middle.

Male.—Unknown.

Length 6.3 mm.; width 2.8 mm.

California.

The unique type is probably a female, as the anterior tibie are

not modified. It is closely allied to sulcatus, but may be readily

distinguished by the alternately wider, very strongly elevated and

more densely punctate intervals, by the decidedly coarser punctures

of the head and pronotum, more strongly rounded sides of the

latter and relatively narrower apex, by its much smaller head, by

the fact that the bases of the elytra and prothorax are equal in

width and by its much larger size,

This species is quite aberrant, not only in the structure of the

prothorax, but in elytral punctuation; the latter is, however, only

an extreme form of that existing in serdalus. It is not as strongly

convex as most of the others.

This species, together with crassipes, constitutes a peculiar

group, distinguished by the acute and prominent basal angles of

the prothorax, coarse abdominal punctuation, and scabrous and

asperate dorsal punctures.

Resembles granulatus, but differs in its much more robust and

rather more depressed form, larger size, sparser pronotal punctures

toward the middle, less acute and abrupt basal angles, much feebler

but more coarsely punctate elytral striz, longer dorsal sete, much

more robust and more strongly dentate anterior tibia of the male

and more robust tarsi.

The prolongation of the apical angles of the elytra is also notice-

able, but to a less extent, in granulatus, and in both is more char-

acteristic of the female.

Crassipes and granulatus form the nearest approach to Conibio-

soma, and thence to Notibius.

CONITBIOSOMA 0». gen.

Body elongate, parallel, setose. Head broadly sinuate at the sides ante-

riorly ; epistoma broadly, angularly sinuate; mentum small as wide as long,

the sides very feebly reflexed, the surface flat, densely punctate, the apex

inflexed ; labial palpi inserted at the sides of the very short corneous ligula,

their base concealed by the mentum; maxille very wide at base, the palpi

normal. Prothorax fimbriate at the sides with very short, robust, posteriorly

recumbent, spiniform sete. Scutellum very short and wide, triangular, not

entering at all upon the disk of the elytra. Abdomen with the fifth segment

strongly inflexed in repose at least in the male. Legs moderate; anterior

tibie not dilated.

This genus is closely allied to Notibius. The single species

resembles Conibius in outward form, and constitutes a transition

from Notibius, apparently having a greater affinity with the latter,

although, if it were not for the fimbriate sides of the prothorax, it

could be quite as easily assigned to the former.

cent laterally. lytra equal in width to the prothorax and but slightly more

approximate punctures, the strie extremely feebly impressed ; intervals each

‘men finely reticulate, finely, somewhat sparsely, subasperately punctate, the

pubescence rather fine and short but distinct. Legs rather short and slender.

Male.—Fifth ventral segment with a very large, transversely oval impres-

sion at the bottom of which there is a feeble transverse ridge.

Length 3.6 mm.; width 1.2-1.4 mm.

Southern California.

The two specimens before me are both males, so that I cannot

determine whether or not the remarkable internal flexure of the

fifth segment in repose is sexual] in nature; it is probable, however,

that this is the case. It is also very probable that the impression

of the fifth segment, given above as a male sexual character, may

be common to both sexes, this being the usual condition in Notibius.

NOTIBIUS Lec.

The sexual modification of the male becomes extremely feeble in

this genus, and the species are otherwise so homogeneous as to

suggest a more persistent and less plastic type than that of Conibius.

The fringe of sete at the sides of the pronotum is more strongly

developed than in Conibiosoma, and is so compact that under low

power it appears to be simply a thickened marginal bead, or other

analogous structure; at the sides of the elytra it is replaced by a

fringe of more slender and much longer, erect and widely distant

sete. This is by far the most important structural character dis-

tinguishing Notibius from Conibius, and its presence in Conibius

elongatus, proves that the latter should be associated with Notibius

rather than the genus in which it was originally placed, but as the

478 Coleopterological Notices.

anterior tibiz are slender I have considered it preferable to separate

it generically.

The anterior tibiz are broadly triangular, which seems to indicate

a burrowing habit, and in this connection it is at least interesting

to note that Ulus, which is also fossorial, possesses the lateral

fimbriz which are so important here. Whether this is a mere co-

incidence, or whether the lateral sete are dependent for their evolu-

tion in any way upon the burrowing habit, I cannot state absolutely

at present, although this is rendered still more probable from the

fact that Celus and Celomorpha, which are fossorial, also have the

lateral fimbriz well developed. The great minuteness of the eyes

in Notibius, as well as the complete absence of wings, should be

noticed in comparing it with Ulus, and apparently shows that while

the latter genus passes a considerable portion of the time above

ground, the former is more essentially subterranean.

In Notibius we first notice a decided change in the character of

the punctuation, especially of the pronotum, where the presence of

the transversely crescentic and asperate type gives a certain pecu-

liarity of appearance. There is considerable variation however in

this respect, the punctures, for example in substriatus, becoming

coarse, deep, rounded and scarcely at all asperate toward the middle

of the disk; these differences can perhaps best be made known by

the following tabular statement :—

Third antennal joint feebly obconical, about twice as long as wide and but

slightly shorter than the next two combined.

Elytral striae not at all impressed, the series of very small, widely distant

punctures exceedingly indistinct; pronotal punctures rather transverse

APHANOTUWS Lec.

The two species of this genus differ by characters which in many

parts of the family might readily be considered generic, but in this

instance I do not think that they possess more than a specific value,

because of the general resemblance throughout the remainder of the

body, which is so marked that without close examination they

might possibly be confounded. The differences may be expressed

as follows :—

Eyes completely divided ; last joint of maxillary palpi rounded at apex and

scarcely perceptibly oblique ; antenne gradually strongly dilated toward

apex, the outer joints compactly joined, the eleventh transversely truncate

throughout the width and much wider than long...........DreViCOrnis

Eyes not completely divided ; last joint of maxillary palpi truncate at apex,

the truncation strongly oblique; antenne rather less strongly dilated

toward apex, the outer joints widely separated and perfoliate, eleventh

slightly wider than long, oval, the apex strongly rounded throughout the

width and with a large sensitive area.........:..0ss0eeeeee eee PAPAIIeCLUS

In general habitus, the two species can be distinguished by the

more elongate elytra of parallelus.

A. parallelus n. sp.—Elongate, parallel, moderately convex, rufo-casta-

neous throughout, strongly shining, glabrous although each puncture has an

excessively minute erect seta. Head about two-thirds as wide as the pro-

thorax, slightly transverse, vertex rather convex, finely, densely punctate;

epistoma subtruncate; eyes large, the dorsal portion oblique and gradually

acuminate; antenne with the third joint slightly longer than wide and dis-

tinctly longer than the second or fourth, the latter equal. Prothorax scarcely

one-third wider than long; sides nearly parallel, evenly and rather feebly

arcuate; apex just visibly narrower than the base, broadly, feebly emargi-

nato-truncate, the apical angles being very slightly prominent but narrowly

rounded ; base transverse and very feebly bisinuate; disk rather coarsely

punctate, the punctures shallow and variolate, finer and sparser toward the

middle, very dense laterally. Scutellum moderate, slightly transverse. Llytra

subequal in width to the prothorax and about three and one-half times as

long; sides nearly straight; apex rather abruptly rounded ; humeri acutely

rectangular and very slightly prominent; disk with eight discal coste which

are abruptly elevated but very fine, the crest of each lying between two series

of excessively minute punctures ; intervals very feebly concave, each with a

single series of fine, feeble, not very closely-set punctures. Abdomen finely,

sparsely punctate, the punctures larger laterally. Length 5.0-6.0 mm.

very noticeably in the structure of the head, but having the pro-

thorax fully one-half wider than long.and the elytra nearly four

times as long as the latter. It will be noticed in Eulabis, Apha-

notus, Eleates, Eledona, and perhaps some other genera having the

elytra finely costate, that the ridges are margined at each side with

a row of minute punctures. This may possibly indicate a bond of

mutual consanguinity.

PHALERIA Latr.

The eyes in some of our species of Phaleria are extremely large

and separated beneath only by a very narrow interval. At first

this might certainly be thought to indicate generic difference, but a

series can be formed showing a gradual widening of the interval,

until in punctipes the eyes are relatively not much larger than in

the European hemispherica or our own globosa. A similar series

can be formed showing a gradual lengthening of the metasternum

from globosa to longula and others. We have here, therefore, two

more variable elements in this unusually plastie genus.

P. gracilipes un. sp.—Very narrow, moderately convex, strongly shin-

ing, pale flavo-testaceous throughout, not at all maculate ; margins not fimbri-

ate. Head moderate, very minutely, feebly and sparsely punctate, the eyes

very large, feebly emarginate by the sides of the head, separated beneath by

a very narrow interval and with the inner sides acutely rounded; antenne

short and robust, joints six to ten wider than long, the eleventh as long as

wide, obtusely rounded. Prothorax fully four-fifths wider than long, the apex

about two-thirds as wide as the base, feebly, evenly emarginate in circular

are, the angles right and very narrowly rounded, not at all prominent; base

transverse, the angles slightly obtuse but not distinctly rounded ; sides evenly,

feebly arcuate; disk impunctate, without trace of beaded basal margin but

with two short feeble striate impressions which are widely distant and near

the base. lytra at base not distinctly wider than the prothorax, about three

times as long as the latter, obtusely rounded at apex, distinctly striate, the

strie very finely, indistinctly punctate, rather feebly impressed toward base,

very deeply so toward apex, the intervals then becoming very strongly con-

vex, extremely minutely, rather sparsely punctate throughout. Abdomen

polished, very minutely and sparsely punctate. Legs rather slender, the

posterior tibie but slightly larger from base to apex and not very densely

spinose. Length 4.5 mm.; width 1.9 mm.

shining and not granulose, with much less robust femora and de-

cidedly less clavate and spinose posterior tibie. In debilis the pro-

notum is finely but distinctly punctate and the elytral striz are

more feebly impressed at base, the elytra being exactly equal:in

width to the prothorax.

In gracilipes the wings are very well developed, being much

longer than the elytra.

PLATYDEMA Cast.

There are two species of this genus which are commonly con-

founded under the name excavata Say. One of these forms was

recently described by me, from an abnormally small specimen, under

the name parvula, and as Say’s description will apply equally to

both, the type being no longer in existence, I have thought it

desirable to give differential diagnoses of the two species under

names which have been already published; they may easily be

separated by the following characters which are taken from the

males :—

Form narrowly oval; eyes moderate ; frontal excavation very large and deep,

the horns separated by a distance which is equal to one-half the entire

width; elytral intervals very minutely and sparsely punctate; femora

sparsely and finely punctate throughout.............s+.ss00 CXCAVaATA

Form broadly oval; eyes much larger; frontal excavation small, moderate in

depth, the horns separated by scarcely more than one-third the entire

width; elytral intervals more convex, more strongly and densely punc-

tate, the strie rather more deeply impressed ; femora finely, rather more

densely punctate, especially toward apex........sssceseceeeeeveeee DALVULA

In addition to the characters given it should be stated that the

frontal horns themselves are quite different in form; in excavata

they are much longer and are perfectly straight, while in parvula

they are shorter, stouter, more gradually acuminate from base to

apex, and are arcuate and curved upward throughout their length.

The type of opacula appears to be a small and rather abnormal

specimen of ruficornis Sturm; the head is more coarsely punctate:

than usual, but otherwise I can find no good character to distin-

guish it.

ELEATES Casey.

The genera of Bolitophagini may be distinguished as follows :—

Eyes emarginate in front.

Prothorax broadly pedunculate at base, the sides strongly, unevenly serrate ;

elytra each with four coarse widely interrupted ridges, the fourth less

evident, the intervals unevenly punctato-tuberculose ... Bolitotherus

Prothorax not pedunculate at base, the sides not serrulate; elytra each

with nine fine equal and entire costz, the intervals uniseriately punctate.

pedunculate at base, the sides finely but strongly serrulate; elytra each

with four interrupted ridges, the intervals each with two rows of coarse

punctures separated by a finer interrupted ridge........ Bolitophagus

Head not deeply inserted, the eyes distant from the prothorax, the pronotum

It will be observed that Eleates is related to Bolitophagus in

nearly the same way that Eledona is to Bolitotherus; in both

of those first mentioned the sides of the prothorax are sometimes

extremely feebly and indefinitely undulated, but never properly

serrate. The species of Eleates may be defined as follows :—

ble divergence from a common ancestor in comparatively recent

geological time.

HELOPS Fab.

The species which have been associated under this name form,

in our fauna alone, a most difficult study. I will not attempt at

present to assign the following species to any of the numerous

genera which have been created at the expense of Helops, but will

simply indicate their relationship with described species.

H. ovipennis n. sp.—Rather broadly oval, distinctly depressed above,

perpendicular at the sides of the elytra, black, with a feeble greenish-aneous

tinge, polished. Head rather wider than long, extremely coarsely, deeply,

not very densely but unevenly punctate; eyes rather more prominent than

the sides before them; epistoma subtruncate at apex: antenne wanting in

the type. Prothorar twice as wide as the head and fully three-fourths wider

than long; apex but slightly narrower than the base, broadly, distinctly

emarginate between the slightly advanced but obtuse and distinctly rounded

angles; base transversely, very evenly truncate; basal angles right, not

rounded and distinctly prominent; sides parallel, moderately arcuate, nearly

evenly so to within one-fifth the length of the base where they become strongly

convergent, very strongly sinuate just before the basal angles; disk trans-

versely, rather feebly convex, with a feeble and uneven median impressed line

which is coarsely, unevenly punctate, but on each side of which the disk is

smooth for a short distance, distinctly explanate near the sides, extremely

coarsely, deeply, very unevenly punctate, the punctures impressed and coa-

lescent. /ytra oval, a little more than three times as long as the prothorax

and, in the middle, fully two-fifths wider; sides strongly, evenly arcuate ;

humeri completely obsolete, very broadly arcuate; apex somewhat acutely

rounded ; disk with deep and widely impressed sulci which are coarsely and

approximately punctate, the punctures rounded ; intervals very strongly con-

vex, very finely, extremely sparsely and unevenly punctate, more or less

widely interrupted, more frequently and thoroughly so near the apex, especi-

ally the alternate intervals; epipleure very wide, extremely dilated toward

base where they are fully one-half as wide as the entire metasternum includ-

ing the episterna. Abdomen longer than the entire remainder of the body

including the head, transversely convex, polished, almost completely impune-

tate, each segment with a large feeble oviform impression near the side; meta-

sternum extremely short, between coxa and groove less than one-half as long

as the first ventral segment. Legs rather short and slender, finely, extremely

California (Mojave Desert).

A single mutilated specimen of this unusually isolated species

was found dead by Mr. Dunn ina decaying stump. It cannot be

compared with any other of our species and is remarkable because

of its oval elytra, with very wide epipleure and totally obsolete

humeri, and its extremely coarsely and deeply sculptured but

polished upper surface. It is one of our largest species.

Although the punctures of the elytral series are coarse, they are

not as wide as the impressed sulci and only about one-fourth as

wide as the intervals.

H. guadalupensis n. sp.—Elongate, subparallel, convex, shining,

piceous-black ; under surface and legs dark rufo-piceous; antenne fuscous.

Head a little wider than long, very coarsely, deeply punctate, the punctures

forming long interlacing rug, but finer, round and distinctly separated on

the epistoma, the latter truncate; eyes transverse, very strongly convex, more

prominent than the sides before them ; antenne slender throughout, two-thirds

as long as the elytra in the male, one-half as long as the latter in the female,

tenth joint more than twice as long as wide in the male, one-third longer than

wide in the female. Prothorax about one-fourth wider than long; apex equal

in width to the base, broadly, evenly arcuate throughout, the angles right and

narrowly rounded; base truncate; basal angles very broadly obtuse and

rounded; sides parallel, very evenly and rather feebly arcuate throughout ;

disk evenly, feebly, transversely convex, coarsely, very deeply and extremely

densely punctate throughout, the punctures forming short interlacing furrows

and very narrow intervening rug, not appreciably sparser toward the middle

in the male, but slightly so in the female. /ytra three times as long as the

prothorax and more than one-third wider, parallel, the sides but just visibly

arcuate; humeri distinct but narrowly rounded ; disk with fine but deep and

abrupt strize which are finely catenulate, the punctures totally disappearing

toward apex; intervals very feebly convex, extremely minutely and sparsely

punctate, each with a single series of small feeble and distant tubercles, only

visible toward the sides and apex. Abdomen finely but distinctly and somewhat

sparsely punctate; metasternum between coxa and groove subequal in length

to the first ventral segment in both sexes. Legs rather long and slender, the

hind tibiw straight, pubescent throughout; anterior tarsi very feebly dilated

in the male. Length 11.0 mm.; width 4.2 mm.

Island of Guadalupe.

This species is to be placed near bachei Lec., but in considering it

a variety of that form, Dr. Horn (Trans. Am. Ent. Soc., V, p. 201)

has overlooked an important structural character relating to the

prothorax. In bachei the sides of the prothorax, in a vertical

direction, are narrowly rounded, without trace of marginal bead,

while in guadalupensis they are acute and have a fine acute mar-

ginal bead throughout the length. Among other differential char-

acters of bachet may be mentioned the elytra not distinctly wider

than the prothorax and without grooved striz, having simply rows

of fine punctures which extend to the apex, the metasternum much

shorter, and the penis acutely produced at apex and not grooved;

in guadalupensis it is broader and narrowly truncate, with a broad

dorsal groove; in these species the penis is sparsely clothed with

short robust spines which are reflexed in position, like the teeth of

certain reptiles. Both of the species here compared are distin-

guished from others by the small widely spaced tubercles of the

elytral intervals, which are more pronounced in bached; this char-

acter may indicate a community of origin, but at the present time

they are certainly abundantly distinct. There are certain characters

also which ally the present species to ciésteloides, the male intro-

mittent organ being truncate in that species and differing very

strikingly from the finely acuminate apex as seen in bache?.

H. callosa n. sp.—Elongate-oval, very convex, feebly shining, castaneous

to piceous throughout, sometimes paler beneath. Head fully as long as wide,

rather coarsely, extremely densely punctate and dull, the punctures closely

crowded throughout; apex transversely truncate; eyes a little more promi-

nent than the sides before them, very strongly convex, transverse and sur-

rounded by the usual very deep groove; antenne one-half as long as the body,

rather robust but not in the least incrassate, joints eight to ten just visibly

decreasing in length, the latter one-half longer than wide, eleventh longer.

Prothorax one-fifth wider than long, the apex just perceptibly wider than the

base, broadly, feebly arcuate, the angles slightly obtuse and narrowly rounded ;

base transversely truncate; basal angles obtuse but not in the least rounded,

distinct but not prominent; sides feebly arcuate anteriorly, slightly conver-

gent and more nearly straight thence to the base; disk usually widest a little

before the middle, coarsely, very deeply and extremely densely punctate

throughout; sides rather obtuse but with a fine beaded margin which is in-

variably present near the base and sometimes traceable throughout the length.

Elytra elongate-oval, about three times as long as the prothorax and, in the

middle, scarcely one-fourth wider; humeri slightly obtuse, not distinctly

rounded but not in the least prominent; apex rather narrowly rounded; disk

with distinctly impressed striz, which are coarsely, deeply punctate, the

punctures approximate, perforate and greatly elongate; intervals moderately

convex but very strongly so toward apex, extremely finely, sparsely and

irregularly punctate. Abdomen rather coarsely, moderately densely punctate ;

metasternum between coxa and groove equal in length to the first ventral

pubescent throughout; femora coarsely, deeply and densely punctate. Length

New Mexico (Fort Wingate). Dr. Shufeldt.

The description is taken from the male; the female does not

differ greatly but is larger, the antenne slightly longer than the

head and prothorax, joints eight to ten decreasing rapidly in length,

the latter but slightly longer than wide, the elytra a little more

inflated and from one-third to one-half wider than the prothorax.

This species is allied to attenuata Lec., but differs in its shorter,

more transverse prothorax, with less strongly arcuate apex, and in

the much more impressed and coarsely punctate elytral strie. It

varies greatly in size, but the prothorax is equally transverse

throughout the seven specimens which I have before me. The

epipleure are narrow throughout as usual.

ERGATES Serv.

Subgen. Tricuocnemis Lec.

The high regions of New Mexico and southern Colorado con-

stitute a peculiar faunistic region or province, containing a large

proportion of strictly endemic species; in support of this statement

scores of examples might easily be cited. The genera to which

these species are referrable are generally widely distributed, but in

several instances which may or may not be indicative of a more

general tendency, the genus—as in Thyce—reappears only in the

true Pacific coast fauna, without inhabiting the intervening dis-

tricts as far as known

For a long time past we have had specimens in our cabinets,

belonging to the present genus, from New Mexico, and others from

northern California to British Columbia, but none whatever from

the intermediate regions; this fact alone should have led us to

examine these specimens somewhat critically. It may be stated as

the result of such an examination that the well-known rule above

mentioned is thoroughly supported in this case, for it is perfectly

evident that the New Mexican form is specifically distinet from the

California representatives called spiculatus by LeConte, and subse-

quently described under the names Macrotoma californica and

spiculigera by White.

The differences may be expressed as follows the characters refer-

ring to the males only :—

Genz produced in a very acute dentiform process at apex; third antennal

joint subequal in length to the prothorax ; metasternum with a fine

carina almost throughout its length; densely pubescent pads of the

posterior tarsi not divided by a glabrous line except near the base of the

first joint; fifth ventral segment with the sides strongly convergent from

base to apex, the latter about one-half as wide as the base, very feebly

incurvate, the angles obtuse but not at all rounded ...spiculatus Lec.

Gene rectangular, not rounded but without acute process; third antennal

joint distinctly longer than the prothorax; metasternum without median

carina except in posterior third ; spongy-pubescent pads of the posterior

tarsi divided throughout by a fine glabrous line; fifth ventral segment

having the sides feebly convergent, the apex fully three-fourths as wide

as the base, broadly, strongly sinuate, the angles extremely obtuse and

AM CIS HIMCTeeassesciosclerciecsieestess ons eoniarsneciersices cceieesiees MAC OMMEXITCAMMUES D.Sp.

In general habitus the two species are easily distinguishable, the

protborax and elytra of spiculatus each being much longer and

more convex than in neomexicanus, but the differences in the sexual

modifications at the apex of the abdomen—shown on the accom-

panying plate—are of course conclusive.

The American representatives of Ergates differ from the Euro-

pean, to a considerable extent, in the length of the antenne and

anterior legs in both male and female, and also in the denticulation

of the sides of the prothorax, one of the median teeth being much

stronger than the others in the European species. It seems proper

therefore that the name Trichocnemis Lec. should be preserved, if

not with full generic value, at least as a subgenus.

Although the last two species differ conspicuously from harrisi,

I have been unable to detect the slightest generic divergence. The

metasternal side-pieces being triangular, more strongly so and also

a little shorter in spiculum than in pilosicornis.

T. spiculum n. sp.—Form rather slender, parallel, moderately convex,

shining throughout, dark castaneous; upper surface almost glabrous, the

hairs growing from the sparse pronotal punctures very short and inconspicu-

ous; sterna rather densely pubescent, the hairs not very long; abdomen

sparsely but distinctly pubescent. Head nearly as long as wide, coarsely,

unevenly punctured; eyes large, nearly as in harrisi but more narrowly

separated above and beneath; antenne five-sixths as long as the body,

robust, strongly compressed, glabrous, finely, extremely densely punctato-

scabrous and rather dull, first, second and the extreme basal part of the third

joints only, polished and coarsely punctate; basal joints in length propor-

tioned nearly as in harrisi, eleventh joint very long and slender, compressed,

fully two-thirds as long as the tenth and abruptly narrower in apical third.

Prothorax scarcely one-third wider than the head, a little less than twice as

wide as long; base and apex feebly lobed in the middle; disk very convex,

almost perpendicular at the sides, the marginal line not very prominent ;

median groove entire, broadly, feebly impressed, the surface throughout very

coarsely and unevenly punctate, sparsely so toward the middle, very coales-

cent, the pubescence becoming extremely short but denser toward apex.

Prothorax a little more than twice as wide as long measured from the base of

the spines; apex subtruncate, slightly narrower than the base, the apical

angles right, not rounded, slightly everted and laterally prominent; base

transverse, very broadly, feebly lobed in the middle; sides obtusely angulate,

disk strongly impressed along the basal margin, without distinctly impressed

median line, very coarsely, deeply punctate, the punctures very widely and

sparsely scattered toward the middle, extremely coarse, dense and unevenly

and apical third, very coarsely, deeply but not very densely punctate toward

base, the punctures gradually becoming smaller and denser from base to apex.

Sterna with very short, moderately dense pubescence. Legs extremely slender

throughout, moderate in length. Length 24.6 mm.; width 8.3 mm.

California (Mt. Diablo).

Although represented by a single female, I have no doubt of the

specific distinctness of the present species; from the female of harrisa

it of course differs completely, and from the male of spieulum it

differs radically in the nature of the elytral sculpture, in the form

of the sutural spines and in the extremely fine dense punctuation

of the hypomera, these being completely impunctate, smooth and

polished, with the exception of a few scattered punctures near the

upper margin anteriorly, in spiculum. The marked pubescence

of the antenne, together with the characters above enumerated and

many others, in addition, which are perfectly asexual in harrisi,

seem to show that the species is not closely related to spiculwm.

The type was received from Mr. Dunn with the indicated locality

attached, but it is quite remarkable that such a conspicuous species

should have remained undiscovered in a region so densely popu-

lated, and the locality may therefore possibly be erroneous.

494 Coleopterological Notices.

APPENDIX.

NOTES.

Since the assignment of Lycoptis (anfe p. 311) to the Colydiide,

I have been far from satisfied with this disposition of it, and have

therefore made some additional comparative studies, the result of

which indicates the decidedly greater propriety of associating it

with the Trogositide. Here, however, if we regard tarsal struc-

ture as of primary importance, it must constitute a distinct tribe,

but if tarsal structure be found to be of subordinate value as it is

in the Passandrine for example, the genus should be placed near

Grynocharis in the subfamily Peltine, where its very remarkable

antenne will at once isolate it. In any event it is a transitional

type between the Trogositide and the Cucujide.

The tarsi are slender and undilated and appear to be perfectly

tetramerous—as previously described,—with the first joint smaller

than the second or third.

The anterior cox are very small, transverse and pointed out-

wardly, but are far more feebly developed than in Grynocharis,

being much narrower than the distance separating the apex from

the lateral margin of the pronotum ; in Grynocharts quadrilineata

the latter distance is scarcely more than two-thirds as great as the

coxal width.

The comparative scarcity of fossilized remains of the Coleoptera,

makes the problem of determining the mutual affinities of the forms

at present existing on the earth, a rather more difficult one than in

the case of vertebrates, where the ancestry can often thus be quite

conclusively traced, and among the Coleoptera there is no portion

of the complex clavicorn series, so difficult to classify in a natural

manner, as those groups clustering about the genera Colydium,

Rhysodes, Lyctus, Monotoma, Silvanus, Passandra, Cucujus, Tele-

phanus and Hemipeplus. These are, judging from their very

Coleopterological Notices. 495

numerous affinities in widely different directions, in all probability

the direct and comparatively unmodified descendants of extremely

ancient types, from which have diverged at different epochs a large

proportion of the modern representatives of the order.

‘lo discuss all or even a considerable part of the relations indicated

by the genera mentioned, would be quite impossible at the present

time. Perhaps the strongest is in the direction of the Tenebrion-

idee, for this is evidenced very plainly in many ways:—in Rhysodes

by the antenne with porous sensitive areas toward the distal ex-

tremities of the last five joints, also visible in Brontes, Hectarthrum

and Passandra, and by its large mentum; in Lyctus by the large

mentum; in the Colydiine by the antenne of Rhagodera and

Anchomma; in the Passandrine by the antenne of Narthecius,

with its small terminal joint, and in the arcuate impression of the

last ventral segment homologous with that of Zopherus; in the

heteromerous male tarsi of the Cucujine ; and finally and even more

decidedly, in the completely heteromerous tarsi of Hemipeplus.

The rhynchophorous relationship is indicated by the larva of

Lyctus and the prosternal structure of many colydiides, also by

the solid antennal club of the Monotomine and many of the Colydi-

ine. Rather more obscure adephagous and cerambycide affinities

bave been noted by authors in Rhysodes, and Lyctus is said to

possess some serricorn affinity through the Cisine.

That Lyctus is however really a clavicorn belonging near the

Cucujing, does not seem to admit of any reasonable doubt for:

1 The tetramerous tarsi of Narthecius and the Colydiine have

been derived from the pentamerous by the atrophy of the first joint,

clearly shown in an intermediate stage in Lyctus, and also, it should

be added, in a still more advanced stage in Prostomis. The tarsus

of Lyctus is in fact very similar to that of Lemophleus. It should

also be remarked in this connection, that the antenne of Lyctus are

precisely identical in structure with those of Berginus.

2 The rhynchophorous relationship of some of the colydiides—

notably Nematidium—has been observed by LeConte (Trans. Am.

Ent. Soc., 1875, p. 168). Now in Lyctus this relationship is also

evident but at an earlier stage of development, the larva of Lyctus

being described as very similar to that of the Scolytide. Although

this does not prove that Lyctus and Nematidium are related, since

their resemblances to Rhynchophora may have been derived along

lines of development convergent upon Rhynchophora but from

496 Coleopterological Notices.

widely different directions, still I believe this fact should be men-

tioned as being at least of possible significance.

3 The mentum in Lyctus, and especially in Trogoxylon, is very

large, filling the entire width of the gular opening and concealing a

large portion of the maxille. In Rhysodes the enormous mentum

is perhaps the most marked peculiarity of the genus, this organ

being developed to a degree probably unknown in any other cole-

opteron, It seems probable that Lyctus may be related in this way

to Khysodes, and thence to the Cucujine.

4 All the important characters of Lyctus, other than those referred

to, find their very satisfactory counterparts among various repre-

sentatives of the Cucujide in the broad sense in which the family

is here considered, and it is not at all easy to perceive any very

striking serrieorn characteristics. In fact no systematist who has

placed Lyctus in the serricorn series has ever dwelt with great

emphasis upon any particular character as proof of the relationship.

DuVal, who seems to have been most candid in this respect, cites

the form of the anterior cox as a reason for refusing it a place in

the Cucujidx, and the divergence of the larva from that of Crypto-

phagus as a reason for disregarding its general clavicorn affinities.

The first of these reasons is of but little moment, as the anterior

cox have many parallels among normal cucujides,’ and the second

is not decisive, for as shown by Lacordaire, the form of the larva

allies it to the Scolytide rather than to the Bostrichinzw,—assuming

of course that the larva has been correctly identified,—and as the

Colydiide are also known to have rhynchophorous affinities, this

argument is rather more effective for a clavicorn than for a serricorn

relationship.

Regarding the Cucujide therefore as a family of Clavicornia, in

These subfamilies, while exhibiting the most diverse and bewilder-

ing affinities and cross affinities in various external directions, are

nevertheless so intimately bound together by certain general pecu-

liarities of organization, that we are compelled either to regard

them as constituents of one very composite family, or to consider

each as a distinct family. There seems to me but little doubt that

the former is the better course to take.

The Passandrine include three tribes, Passandrini, Prostomini

and Nartheciini, depending upon the nature of the jugular pieces

and the antennal structure.

The Colydiinee comprise the genera at present composing the

family Colydiide, the Murmidiini forming a tribe allied to Cery-

lonini and not a subfamily.

The Monotomine include two tribes, Monotomini and Myrme-

chixenini, Hypocoprus bearing a relation to Monotoma which is

almost precisely equivalent to that borne by Smicrips to Rhizo-

phagus. Through the Monotomine the Cucujide are connected

with the Nitidulide by way of the Rhizophagini. In the Mono-

tomini the number of tarsal joints is four throughout, with the third

joint rather smaller than the others, especially in the anterior, but

in the males the posterior tarsi are 3-jointed through the elimination

of the first joint; this is an additional point of similarity between

Monotomine and Cucujine.

The Brontine may be divided as follows :—

498 Coleopterological Notices.

Tarsi cylindrical.

Basal joint almost obsolete, not Gistinct..........ceeceeseeecseceeee eee ee OVORECES

Basal joint small but very distinct, slightly swollen obliquely beneath.

Dendrophagus

Tarsi strongly dilated; basal joint small but strongly, obliquely produced

beneath the basal parts of the second joint.

Third tarsal joint obliquely produced beneath in a truncate or rounded

lobe; basal joint of the antenna elongate; fourth joint of the maxil-

lary palpi large and securiform.

Antenne slightly thickened toward apex ...........000s5++ PSAMMBACUS

Antenne normally filiform throughout ........................ Nelephanus

Third tarsal joint very deeply bilobed; first antennal joint short, oval;

fourth palpal joint slender, conoidal.....................Cryptamorpha

There can be no doubt whatever that these genera should be

associated together. The tarsus of Brontes is truly very different

from that of Telephanus, but that of Dendrophagus is a tolerably

eood intermediate, especially in the structure of the basal joint.

The antennz are of precisely the same type throughout, and the

tarsi are isomerous in both sexes." The genus Platamus of Erichson

is the only one described which is not included in the table; it is

allied to Brontes but differs in its less elongate basal joint of the

antenne.

The Cryptophagide which are allied to the Cucujide, but distin-

guished by the transversely oval and sometimes distinctly more

prominent anterior coxe, should be composed of the subfamilies

Cryptophagine, Mycetophagine, Cisine and Sphindine.

The principal reasons advanced by the earlier systematists,—to

whose views Lacordaire deferred somewhat against his will,—for

considering the Ciside a family of the Serricornia, were in great

measure superficial and based upon a general resemblance to the

Anobiini, as expressed by the generally cylindrical form of body

and somewhat retractile head. On examining the anatomical strue-

ture of the under surface I perceive no radical difference whatever

between Cis and many of the cryptophagides, and have no doubt at

all that the genus is really clavicorn. It cannot be denied, how-

ever, that the morphological resemblances to the anobiides above

1 The three specimens of Cryptamorpha desjardensi (= hubbardi Cas.), before

me, two of which I believe to be male and female from certain differences in

the antenne, have the hind tarsi normally pentamerous throughout. The

statement made by Wollaston—apparently with some misgiving—that the

tarsi of the male are heteromerous is open to the gravest doubt.

Coleopterological Notices. 499

alluded to, undoubtedly indicate an obscure and innate line of con-

sanguinity; this is indeed quite conclusively proven by the fact that

in Rhipidandrus, which seems to be more closely allied to Cis than

to any other genus, the antenne are strongly pectinate toward

apex, the pectinate portion forming an angle with the basal portion.

This character however, when weighed against its general organiza-

tion, does not make it a serricorn, any more than the purely clavate

antennz of Hydnocera prove the latter to be a clavicorn.

It does not seem possible in this connection to avoid attaching

some weight to the resemblance, pointed out by Lacordaire, between

the larva of Cis and Cryptophagus,’ and, it may be added, the

superficial resemblance of certain cisides to Diplocelus is very

remarkable, even more so in fact than the real resemblance of any

species of the former which I have examined to any anobiide or

bostrichide.

The retractibility of the head in Cis is generally very slight and

is scarcely greater in degree than in some species of Atomaria. In

the latter I do not find the anterior coxe rounded, but transversely

oval, exactly as in Cryptophagus. Sphindus is quite certainly

not entitled to rank as a distinct family whatever be the position

assigned it; the enlarged basal joint of the antennz is analogous

to that of Atomaria. In the latter genus the anteriorly prominent

clypeus between the antenne is indicative of a characteristic which

becomes very prominent in certain cisides.

In the Cryptophagide as here considered, the parts which seem to

offer the greatest diversity of form are the clypeus and tarsi; most

of the other characters appear to be very persistent in structure.

The tarsi of Telmatophilus and Loberus are analogous in taxo-

nomical import to those of Telephanus and Psammechus of the

Cucujide.

It should be noted in conclusion that the scope here proposed for

the families Cucujide and Cryptophagide, brings together in the

1 In placing the Ciside near the Ptinide DuVal (Gen. Col. III, p. 236),

seems to imply by the language used that the resemblance of the larva of Cis

to that of Cryptophagus is a matter of very slight importance, as so little is

known of larval affinities, but two pages before in maintaining that the Lyctine

do not belong near the Cucujide, he assumes the divergence of larval form as

a very powerful factor in his argument—an inconsistency which, it may be

added, greatly reduces the weight of M. DuVal’s conclusions as far as com-

parative studies of the larve are concerned.

former the greater part of the subcortical clavicorns, and in the

latter a Jarge proportion of those having fungivorous habits. From

purely biological considerations therefore this arrangement would

seem more natural than the wide dispersal of these perplexing

groups of genera now considered necessary.

III.

The present opportunity is taken to give the general characters

of an interesting addition to the Cucujide.

PLANISMUS n. gen. (Silvanine).

Body subparallel, rather depressed, extremely sparsely, inconspicuously

pubescent. Head porrect. Eyes at the base near the prothorax, very large,

convex and prominent. Epistoma slightly prolonged, transversely truncate

at apex; suture entirely obliterated. Labrum short, transverse. Mandibles

very robust but short, flattened, deeply notched at apex, bicarinate at the

sides, the interval with a line of short robust sete, the under surface longitu-

dinally excavated in arc, the feeble excavation bounded internally by a very

fine raised line. Mentum rather large, transverse, with a triangular carina.

Labial palpi moderate, the third joint longer and a little thicker than the

first two combined, longer than wide, oval, narrowly truncate at apex. Max-

illary palpi cylindrical, the fourth joint as long as the first three, slender,

much narrower than the second or third, cylindrical and very feebly arcuate.

Antenne robust, 11-jointed, with an abrupt loose and parallel 3-jointed club.

Pronotum with a short longitudinal carina on each side in basal third or

fourth and at lateral fourth. Scutellum short, transversely oval. Elytra

with feebly impressed rows of distinct impressed punctures, the scutellar

series long. Prosternum distinctly but not widely separating the coxe, the

process prolonged slightly and expanded behind them, the apex truncate and

resting loosely on the anterior margin of the mesosternum. Anterior coxe

small, rounded, deeply inserted, the cavities narrowly closed behind; inter-

mediate larger, rounded, moderately separated; posterior transverse, rather

approximate. Legs rather short and robust; tibial spurs minute; tarsi

5-jointed throughout, the basal joint much longer than the second, the fourth

very small, fifth slender, as long as the three preceding combined ; first three

very robust and, on all the tarsi, having each a finely spongiose pad beneath ;

ungues moderate, slightly dilated internally near the base. Abdomen con-

sisting of five nearly equal free segments, the sutures fine and straight.

This genus belongs near Nausibius, but differs in the more robust

and spongiose tarsi, in its much less broadly closed anterior coxal

cavities, and very greatly in general appearance. In some respects

it seems to be intermediate between the Silvanine and Cucujine,

Coleopterological Notices. 501

but in antennal and tarsal structure it is as strongly silvanide as

any other.

P. floridanus n. sp.—General form elongate-oval ; integuments polished,

dark rufo-testaceous. Head rather finely but deeply and somewhat densely

punctate; antenne about one-half longer than the head. Prothorar about

one-half wider than the head and two-fifths wider than long; apex a little

narrower than the base, truncate, the apical angles slightly obtuse but not

rounded and just visibly prominent anteriorly ; base very feebly arcuate, the

angles distinctly rounded but with the extremity of the basal bead forming

a minute prominent lateral point; sides very feebly convergent from base to

apex, evenly, very feebly arcuate, without trace of inequality, the marginal

bead finely, feebly reflexed ; disk evenly, very feebly convex, rather sparsely,

somewhat coarsely but feebly punctate, the regions near the basal carine very

feebly impressed. lytra twice as long as the head and prothorax combined,

in the middle nearly one-fourth wider than the latter, the two bases equal ;

sides parallel, broadly, feebly, evenly but distinctly arcuate; apex evenly

rounded; disk feebly but almost evenly convex, the punctures of the series

deep and distinct, the intervals each with a single series of widely spaced

very minute and scarcely visible punctures bearing fine recumbent hairs.

Abdomen polished, finely, not densely punctate. Length 3.4 mm.

Florida (Biscayne Bay). Mr. Schwarz.

The elytral suture is finely beaded, the bead becoming very evi-

dent toward apex, where also the surface near the suture becomes

distinctly impressed,

PV:

The cabinet formed by the late Dr. G. M. Levette, of Indianapolis,

which has just come into the possession of the writer by purchase,

contains a large amount of valuable material, especially from the

Carolinas, Georgia, Florida and Colorado, much of which was pro-

bably collected by Morrison. <A large proportion of this material

is either undetermined or erroneously identified, but its value may

be inferred from the fact that in the field covered by the present

paper, I observe specimens of Hmmenastus fallax, Epitragus fusi-

formis, Asida angustula and quadricollis, Coniontis pallidicornis,

genitiva, parallela, parviceps, and setosa, Eleodes arcuatus and

E. prominens; also Helops impolita and tumescens, and several

remarkable new forms which will be made known at a future

opportunity,

In this material there is a series of four specimens of Hleodes

cognatus, which plainly indicates that the latter is a species different

from extricatus, and that the fine punctures of the type are normal ;

these representatives show, however, that they are generally disposed

in series which are alternately narrowly and slightly more widely

spaced, the intervals being alternately flat and slightly convex, the

sculpture in general greatly resembling that of fusiformis; the

original type is not a perfectly characteristic example.

A few additional remarks concerning the species described in this

and the preceding paper, based in great measure upon the material

above mentioned, should be added as follows :—

The aggregation of fine punctures in widely distant longitudinal

series, is a character common to all of our species of Edrotes except

nitidus, in which I can find no trace of it; the aggregation of the

punctures is generally evidenced by a certain indefinitely vittate

appearance, amounting to well defined series in ventricosus. This,

together with the fact that in the unique type of globosus I find

the sete are broken off in a remarkably even manner and that the

pubescence in the normal state is really long and erect, necessitates

a new arrangement of the species as follows :—

Elytral punctures extremely fine and sparse.

Each elytron with three narrow lines in which the punctures are more

defined series, in which the interspaces between the larger punctures

become distinctly, though finely, and rather sparsely punctate.

Triorophus lecontet differs from nodiceps in its more elongate

form, less developed frontal umbo, much less transverse prothorax—

the form of this part being nearly as in lavis—and in its coarser

elytral punctures. It is however more closely related to nodiceps

than to levis.

Emmenastus acutus seems to vary greatly in the distinctness of

the rows of punctures, some specimens before me having the series

near the suture quite well developed. Under these circumstances

it is proper to assign the Truckee specimen, referred to under £. ater,

to L. acutus. E. coarcticollis has the head smaller, the prothorax

Coleopterological Notices. 503

much shorter and more transverse, and the elytra polished through-

out and not dull toward apex as is the case in acutus.

Asida angustula, of which I have now seen nine specimens, differs

from muricatula in its constantly much narrower and more parallel

form and shorter and sparser pubescence; the legs are, however,

similarly clothed with short inclined sete, and are devoid of long

flying hairs.

Blapstinus californicus Mots. must be regarded as a manuscript

name, the original description being completely inadequate for its

recognition ; it was probably taken in or near the western part of

Texas.

The small white object previously described (Col. Not. I, p. 196),

has been further reported upon by Mr. Beaumont, who states that

it is found in large numbers in all the nests of the termites, irrespec-

tive of species, and that it runs with such velocity as to be very

difficult to capture, turning and jumping slightly off its feet with

great facility, apparently by means of the fleshy abdominal appen-

dage, of which it makes constant use.

These facts, in conjunction with its general organization, prove

it to be a member of the order Thysanura, belonging to an unde-

scribed genus, and constituting a family quite different from either

the Lepismidz, Campodide or Poduride. For the genus I would

propose the name GasrRroTHEus, and the species may be called

G. termitarius.

The mandibles are short and very robust, the outer contour

strongly, evenly arcuate, the apex abruptly produced and very

finely acuminate. I cannot perceive any distinct internal denticu-

lation.

BY R. P. WHITFIELD.

J. DeEscrIPTIoNs OF Fosstts FROM THE PALozotc Rocks or Onto.

In submitting for publication the following descriptions and

observations of Ohio fossils I feel it due to myself to account for

its detached and apparently incomplete character, to state that this

arises from the fact, that it is essentially a report on certain groups

of fossils submitted to me, partially for the purpose of ascertaining

their horizons or for determining their relations to other beds the

horizons of which were supposed to be already known. In the

effort to carry out these objects, besides the specimens and informa-

tion which I have received from Dr. Newberry, I have been aided

by the loan of specimens and by other assistance from President

Edward Orton, of the Ohio State University, and by the Hyatt

Brothers, students in that institution, who have furnished me much

information in regard to localities and horizons of different species,

as well as lists of those known to occur in particular beds in the

vicinity of Columbus; and also with specimens from their private

collections. To the late Rev. E. B. Andrews, of Lancaster, Ohio,

I am also indebted for the use of many of the specimens illustrating

the Maxville limestones

The fossils illustrated on Plate V, represent forms that are found

exclusively in the hydraulic cement beds of the State, which repre-

sent the lower part of the Lower Helderberg and Waterlime groups

of New York. The character of the fossils is such that no com-

ments are necessary in regard to the horizon they represent. Plates

VI to X inclusive, contain figures of species from the limestones

below the horizon known as the ‘‘ Bone bed” in the vicinity of

Columbus, Ohio, and are to a great extent illustrations of hereto-

fore undescribed forms. The forms represented on Plate XI are,

with one exception, known species; they represent horizons not

506 Contributions to Invertebrate Palzxontology.

hitherto recognized within the limits of the State, and require

something more than a passing notice; I have therefore made

some remarks upon them preceding their descriptions, more ex-

tended than would be convenient in this place.

The species illustrated on Plate XII are from the Huron and

Erie Shales with one exception (Aristozoe canadensis) and the

remarks preceding their description will sufficiently explain their

grouping.

Those illustrated on the two following Plates, Nos. XIII and

XIV, are all from the limestone layers known as the Maxville

limestones, and although several are of previously undescribed

species, enough of them are recognized forms to fully establish

their geological horizon, which appears to be equivalent to the St.

Louis and Chester beds of Illinois and the surrounding States.

This conclusion, I believe, had been reached by Mr. F. B. Meek

during his work on the Ohio fossils, at least his labels on some

specimens of Spirifera contracta in the State Cabinet at Columbus

would indicate this conclusion. The possibility of fully and satis-

factorily identifying any of the divisions of the Lower Carbonifer-

ous formations of the more western States among the beds repre-

sented beneath the true Coal Measures of Ohio, must certainly be

considered as an advantage in the study of these formations. Not

only is this true from a stratigraphical point of view as enabling

us to identify a stratum or formation over a much greater extent of

country and thereby trace out and locate its history in time; but

also paleontologically, as enabling us to satisfactorily identify many

of the slightly varying forms of fossils represented in these beds

with those from other localities, instead of having them described

as distinct species, founded upon minute or imaginary differences

resulting principally from a change in the state of preservation or

of the conditions of life under which they may have existed during

the deposition of the sediments in which they are now found,

There seems to be a constantly growing tendency to describe as

new species forms which vary in the slightest particular from the

established species, and it often arises from the inability to satis-

factorily identify the beds in which they are found with those from

other localities where the stratigraphical relations are already known,

and I cannot but regret that it is not practicable to work out the

fossils of other of the Ohio formations, as I am fully persuaded there

are several of these which could be positively identified with well-

Contributions to Invertebrate Paleontology. 507

known formations in other States, were this done. This is shown

by the fossils from the red Iron-stone beds of the Waverly at

Sciotoville, Ohio, among which are forms which indicate the Bur-

lington or Burlington and Keokuk beds of Iowa and Illinois. On

Plate 10, fig. 4a—c, of Vol. II, Pal. Ohio, is represented a Productus

in the condition of an internal cast, which when studied in numbers

in connection with Productus flemingi var. burlingtonensis Hall,

from Burlington, Iowa, and Quincy, Lllinois, cannot fail to be iden-

tified as the same species, while the Hemipronites crenistria of the

same plate scarcely differs from Orthis keokuk of the same beds;

and on Plate 14 of the same volume, fig. 6, is already identified with

the Athyris lamellosa of the Iowa locality. Although there may

be many entirely new forms embraced within the vertical limits

occupied by these same shells at the localities from which they are

derived, I do not think this a sufficient reason why they should be

considered as other than equivalents of the Burlington and Keokuk

beds of the western States above mentioned.’

Plate XV is occupied principally by new forms from the Coal

Measures, while Plate XVI contains many previously described

species. The smaller forms represented being mostly illustrations

of species found in two separated layers of chert, within the limits

of the Coal Measures, near Webb Summit and at Mrs. Banks’s

Farm, Falls Township, Hocking Co., which were particularly ex-

amined for determining their horizons, and the figured specimens

were obtained from them in place. _These species sufficiently mark

their places as within the true coal bearing series.

For the interesting new forms illustrated on Plate Ke IT am in-

debted to H. Moores, Esqr., of Columbus, Ohio, and to Mr. Somers,

of the same place, who have taken pains to collect and send to me

for examination much of the well-developed fauna of Carbon Hill,

Hocking Co., Ohio. On this same plate is represented a new genus

and species of air breathing Mollusk, the discovery of which in the

Coal Measures of Marietta, Ohio, is an exceedingly interesting fact,

as showing the wide distribution over the American coal region

during its formation, the conditions of climate and terrestrial cir-

cumstances which permitted the existence of this form of life to

extend over Ohio, Indiana, and Nova Scotia.

DESCRIPTIONS OF SPECIES.

SPECIES FROM THE HYDRAULIC LIMESTONES OF THE

LOWER HELDERBERG GROUP.

Streptorhynchus hydraulicum.

PuatE V, figs. 1-3.

Streptorhynchus hydraulicum Whitf., Ann. N. Y. Acad. Sci., 1882, p. 193.

Shell small to minute, the largest individuals yet observed not exceeding

five-eighths of an inch in greatest diameter, while the most of those observed

are not more than two-thirds as great. Valves depressed convex, or, more

commonly, appearing very flat, as seen on the surface of the stone. Hinge-

line straight, nearly as long as the width of the shell below, and the latter

usually more than the length, frequently nearly once and a half as great.

Ventral valve characterized by a very narrow and nearly vertical cardinal

area, and a usually more or less twisted or otherwise distorted beak. Dorsal

valve slightly more convex than the ventral, with a perceptible mesial depres-

sion extending from beak to base, becoming broad and undefined below the

middle of the length. Surface of the shell marked by coarse and somewhat

rigid radiating strie, which are distinctly alternating in size; the principal

ones proportionally very strong.

The small size of the shell, with the strong radiating and alter-

nate strie, are distinguishing features of the species. There is no

species resembling it, to any degree, among the fossils of New York

rocks of a corresponding age. It presents much more the features

of forms of the genus from the Coal Measures than any heretofore

described from Silurian rocks of America, and will not be readily

confounded with any known species.

Spirifera Vanuxemi Hall.

The shells of this species are abundantly scattered over the sur-

face of certain layers of the Waterlime rock, at Peach-Point, Put-

in-Bay Island; associated with Leperditia alta of Conrad, and

occur of all sizes from those of not more than an eighth of an inch

in transverse diameter to those of about five-eighths of an inch, and

present all the features of those of the Tentaculite limestone of

eastern New York. The form is transversely oval in outline and

convex in profile, on each side; the ventral being the most rotund ;

cardinal angles rounded and cardinal line short; ventral beak

strongly incurved. The shell is marked on each side of the mesial

fold or sinus by about four strong, rounded plications and are sepa-

rated by concave spaces, which on the ventral valve appear of about

equal width with the plications, but on the dorsal are narrower and

somewhat sharper in the bottom. The mesial fold is fully twice as

wide as the strongest plication, is somewhat regularly rounded or

depressed convex, while the mesial sinus of the ventral valve appears

narrower and deeply concave. The surface of the shell is marked

by fine transverse or concentric striz which are strongly undulated

in crossing the plications and fold, and under a magnifier are seen

to present considerable regularity in size and arrangement.

The species presents many similarities to S. crispus Hisinger ;

as it occurs in the Niagara group of New York and other places in

America, as well as to those of European localities. In fact it is

quite difficult to see wherein they differ, but as the Lower Helder-

berg forms are nearly always found only as separated valves and

more or less exfoliated, there is some difficulty in instituting satis-

factory comparisons.

Formation and Locality.—In hydraulic limestone of the Lower

becoming more and more depressed until it becomes concave toward the front,

forming a very distinct mesial sinus; front slightly prolonged and bent up-

ward. Dorsal valve very convex in the upper part, approaching gibbous on

the umbo, the beak small but strongly incurved ; front of the valve truncate

or slightly emarginate to accommodate the front extension of the ventral, but

no distinctly defined mesial fold exists. Surface of the shell marked only by

numerous concentric lines of growth, some of which are strongly defined.

The specimens of this species noticed from Ohio are smaller than

the usual size of individuals from New York, but present the usual

features of the species as shown on the specimens figured by Prof.

Hall, on plate 39, Pal. N. Y., vol. 3, fig. 3, f and k, which is by far

the most common and characteristic form among those from that

State. The Ohio specimens are internal casts, and show the slit in

the dorsal valve caused by the removal of the median septum very

distinctly. The casts: of the ventral side show the characteristic

form of muscular impression, but it is small and faintly marked.

Shell rather below a medium size, somewhat oblate in form, at least as

wide as long, the narrowing of the beak giving an oblate appearance to the

shell. Valves usually ventricose and sometimes highly convex, generally a

little more full above than below the middle; margins of the shell regularly

curved except near the beak, which is slightly projecting and moderately

incurved. Surface of the valves smooth, but each characterized by a slightly

impressed mesial sinus along the centre, more strongly marked on the ventral

than on the dorsal side, aid which not unfrequently causes an emargination

of the front border of the shell.

The specimens of this species from Ohio are mostly in the con-

ditions of internal casts, but a few among them retain the substance

of the shell in the condition of a white chalky coating, sufficiently

well preserved to afford material for description and illustration.

They vary much among themselves in the form of the outline and

in the degree of convexity of the valves, a few of them presenting

a globular form, while others are but moderately convex. They

sufficiently resemble the New York forms to be readily identified

where the shell is retained, but in the condition of internal casts

are not so easily recognized. The muscular imprints as seen on

them are small and faint, those of the dorsal valve narrow and

elongated, and that of the ventral is quite small, though deep, and is

confined to the rostral portion of the valve.

Formation and Locality.—In a soft drab-colored hydraulic lime-

stone referred to the Lower Helderberg group, at Greenfield, Ohio,

associated with forms which appear to represent a Nucleospira.

Shell attaining a rather large size for the genus, being often more than half

an inch in transverse diameter, and when of medium or large size, strongly

ventricose or rotund. The younger individuals, however, are depressed-

convex or lenticular in profile. Length of the shell as great or greater than

the transverse diameter. Beaks small and incurved, not at all conspicuous.

Valves marked by a slight depression along the median line, strongest on the

ventral side.

This species, like all those of this formation yet obtained in Ohio,

are mostly internal casts and impressions; consequently the true

features of the shell are not readily obtained. The general features

of the species, however, are preserved sufficiently for identification

and comparison, when good individuals are selected. The shell

bears much resemblance to N. ventricosa, Con., from the Lower

Helderberg group of New York, in its general form, except the

much greater size and more elongated form of the adult individuals.

There is more difficulty in separating them satisfactorily from the

casts of Meristella bella Hall, with which they are associated. In

fact, it is all but impossible to do this with certainty, unless they

are in a good state of preservation, as the difference in the form of

incurved beaks, are the only features that can be relied upon.

Rhynchospira formosa Hall, Pal. N. Y., vol. 3, p. 485, pl. 95 A, figs. 7-11.

Shell small, the specimens observed not exceeding five-sixteenths of an inch

in length, by about one-fourth of an inch or less in width; elongate-ovate in

form, widest below the middle and narrowing at the beak on the ventral side,

the apex being slightly incurved. Valves highly convex, with a slight depres-

sion along the middle. Surface of the shell marked by about twenty-two -

simple, round, radiating plications, two of which in the middle of the valves

are more slender than the others and depressed below their level, forming a

slight mesial sinus on each valve.

The shell, or rather the impression of the shell of this species as

left in the rock, appears to represent an adult specimen, but is very

much smaller than those of the Lower Helderberg group of New

York, or those of R. evax in the Niagara group at Waldron,

Indiana, but possesses all the essential specific characters of the

species except in this one particular. The species as recognized in

the Silurian rocks of Perry County, Tenn., resembles exactly this

from Ohio, both in size and general characters. It has proven

hitherto quite rare, but might possibly be found in greater abun-

dance were it sought for; the specimens noticed occurring on blocks

of stone selected for other fossils.

that of the ventral valve moderately incurved, and the other rather strongly

incurved. Surface of the shell marked by from sixteen to eighteen simple

plications, four of which are strongly elevated on the front half of the dorsal

valve to form the mesial elevation, which does not extend beyond the middle

of the valve, and six or seven may be counted on each side of the valve. The

plications are but slightly elevated, are round on the summit, and do not

extend beyond the middle of the shell, the upper part of which is smooth,

and marked only by concentric lines of growth. The interior of the dorsal

valve is marked by a moderately strong mesial septum, extending from the

apex of the valve to about one-third of its length. The shell appears to have

been also marked by fine concentric lines of growth, some of which form dis-

tinct varices.

This species belongs to the semi-plicated group of the genus, of

which there are many species having close resemblance to it, but

none in rocks of corresponding age or position having very close

affinities.

Pentamerus pes-ovis Whitf., Ann. N. Y. Acad. Sci., March, 1882, p. 195.

Shell quite small, and of a somewhat broadly triangular form, with depressed

convex valves, the ventral side being nearly twice as deep as the dorsal, and

more elongated at the beak, giving it the triangular character ; cardinal slopes

straightened and rapidly diverging ; front broadly rounded.

The species is known only in the condition of internal casts, and as thus ;

seen, the ventral valve is deeply cleft along the median line by the removal

of the central septum, the slit often extending more than three-fourths of the

length of the valve. The filling of the spoon-shaped cavity is proportionally

large, being long and narrow, and not strongly arched. Cast of the dorsal

valve characterized by a proportionally large and broad cardinal plate, from

which project two long and strongly divergent and distant crural processes,

reaching far along the surface of the cast in some cases, while in others they

are quite short. The surface of the valves has been destitute of plications,

but is usually marked in the larger individuals by several strong varices of

growth near the front margin, which give to the shell a prematurely old

appearance for so small a species ; the individuals seldom exceed five-eighths

of an inch in length on the ventral side.

The species is unlike any known form of a similar size, in the

shallowness of the valves, in the erect character of the ventral beak,

and in the deeply divided feature of the cast of this valve. The

dorsal valve is much less marked, and is often destitute of any dis-

tinguishing feature.

Shell of proportionally small size, obliquely rhomboidal in outline, with a

moderately long, straight hinge-line, but little shorter than the length of the

body of the shell below. Left valve depressed convex, with a small, slightly

incurved beak, scarcely extending above the cardinal line. Anterior end

short, and the anterior projection scarcely defined; posterior wing concave

and the posterior margin nearly at right angles to the hinge-line for a short

distance below, then gently curving backward to the rounded postero-basal

extremity ; basal line rounded and on the anterior side of the umbonal ridge

curving rapidly upward to the anterior extremity. Body of the valve convex

and oblique to the hinge, the umbonal ridge broadly rounded. Surface of the

shell marked only by lines of growth some of which are stronger and form

slight varices.

The species is poorly represented in individuals, but the speci-

mens seen are so precisely like those of the Tentaculite limestones

of New York as to be not readily mistaken.

elevated above the cardinal border and rather inconspicuous, situated about

half or rather less than half the height of the shell from the anterior ex-

tremity, proportionally more distant on the larger specimens than on those of

small size. Hinge-line long and straight, extending four-fifths of the length

of the shell behind the beaks and characterized by a narrow but distinct

escutcheon. Anterior end short and full, very obtusely pointed at the longest

part, which is at about the middle of the height, above which point there is a

very distinct but narrow lunule extending to the extremity of the hinge-line.

Basal margin of the valve very broadly curved, slightly emarginate just ante-

rior to the middle and the whole subparallel to the cardinal line. Posterior

extremity sharply rounded below and the upper margin very obliquely trun-

cated ; body of the valve marked by a broad, distinct, mesial sulcus extend-

ing from behind the beak to the broad sinus of the basal margin. The um-

bonal ridge is rather sharply marked and angular in the upper portion, but

becomes less distinctly marked posteriorly ; postero-cardinal slope of moderate

width, very slightly concave in the younger stages of growth but less strongly

marked as the growth advances. Surface of the valves marked by strong,

sublamellose, concentric lines of growth parallel to the outer margin of the

valves.

The shell undergoes considerable change in form and in the

strength of the surface characters between the younger and more

advanced stages of growth; the sharpness of the features being

much reduced on the older portions, by the rounding of the umbo-

nal ridge and of the angularity of both the anterior and posterior

extremities of the shell. The shell differs in several of its external

features from the genus Modiolopsis, possessing a distinct lunule

and escutcheon as well as the angular umbonal ridge, in all of which

features it corresponds with Goniophora.

shields and one body of a species of Hurypterus, which is so dis-

tinetly different from any of those described, that it seems necessary

to class it as a separate species. The differences, so far as seen on

the parts preserved, consist in the form of the cephalic plate, in the

size and position of the eye-tubercles, and in the proportions of the

body as compared with the known forms. There are undoubtedly

other and more important differences in the appendages, but as

these are not preserved on any of the individuals examined, com-

parison is impossible.

The cephalic shield is proportionally broader than that of ZH.

remipes or E. lacustris, and is more regularly rounded or arched

on the anterior border, lacking that subquadrate form characteristic

of those species. The eyes are proportionally smaller, and situated

nearer each other, and also farther forward, as well as being some-

what more oblique to the longitudinal axis of the body. The minute

ocular points are somewhat larger than in HL. remipes, are situated

close together, and are nearly opposite the posterior end of the real

eye-tubercles; they consist of a pair of distinctly elevated rings

surrounding rather deep, although minute, central depressions; the

inner margins of the rings being almost in contact. The head does

not show evidence of having been margined by an elevated or

thickened rim, as in those species, but as the specimens are rather

impressions of the inner surface of the external crust than actual

external surfaces (being more properly internal casts, the substance

of the carapace having been entirely removed), this feature may

not be properly shown. The head-plate more closely resembles

that of H. microphthalmus Hall (Pal. N. Y., vol. iii, p. 407,* pl.

80 A, fig. 7), from the Tentaculite limestone near Cazenovia, N. Y.,

than of any other described species; it differs, however, in being

proportionately much shorter, which gives it a more semicircular

form. The eye-tubercles are also more nearly of the size of those

of that species and similarly situated.

The thorax closely resembles that of H. remipes in its general

form, but the lower three or four segments are proportionally

shorter, giving the posterior extremity a much more compact char-

acter. The principal distinction between the two species, as shown

by the thorax, exists in a difference of the ornamentation of the

surface, as seen on the specimen used, This consists in the minute

spine-like pustules or pointed granules, marking the surface of the

crust, being arranged in irregular transverse lines across the body,

and parallel to the anterior and posterior margins of the segments,

instead of being irregularly disposed, as in all other species de-

scribed. No indication of the longitudinal rows of larger pustules,

marking the median line of the thoracic segments, can be traced,

Valves of the carapace transversely sub-ovate, widest posterior to the middle

and narrowed in front, the proportional height and length being somewhat

variable, but are usually about as two and three. Hinge-line straight nearly

two-thirds as long as the entire valve, extremities salient. Anterior end of

the valves narrowly rounded and the posterior extremity broadly curved ;

basal-line curved but with a scarcely perceptible angularity just posterior to

the middle of the length. Surface prominently convex and a little the fullest

anterior to the middle; occular tubercle small, situated a little below and

just behind the anterior extremity of the hinge-line. Lower margin of the

valves slightly inflected, and in some cases the posterior margin appears to

have been bordered by a slightly thickened rim.

The individuals examined are either internal casts or impressions

of the exterior, owing to which fact the finer surface features of the

crust cannot be definitely ascertained; enough is seen however to

show its identity with those from the Tentaculite limestones of

New York. The species as described by Mr. F. B. Meek includes

this and the following one, which are very distinct species, the dif-

ferences being very strongly marked in the great prominence of

the lower part of the valves of that one, and its strongly sub-

angular form as well as in its greater size. The principal variation

noticed among the individuals of this species, is in the greater

proportional length of some of them, producing a cylindrical form.

This feature is however seen occasionally among those from Scho-

haire, N' Y., but does not appear to be worthy of specific consideration.

Leperditia angulifera Whitf., Ann. N. Y. Acad. Sci., March, 1882, 196.

Carapace of medium size, having a length, in adult individuals, of about

three-eighths of an inch, by a height of one-fourth of an inch in the broadest

part. General form of the outline broadly sub-ovate and widest posteriorly ;

hinge-line straight, equal in length to two-thirds that of the entire valve ;

anterior end a little the shortest, narrowly rounding into the broadly curved

basal line; posterior end broadly rounded. Surtace of the carapace highly

elevated and prominent, forming a strong, somewhat angular, longitudinal

node just within the basal margin, and near the middle of the length. From

this point, the surface slopes somewhat gradually upward to the hinge-line,

with a barely perceptible convexity, except on the anterior end, where it is

more strongly convex, and characterized by a rather prominent and well-

marked ocular tubercle. From the angular node near the lower margin,

there is, on well-preserved individuals, a perceptible angulation, extending

along the surface to the point of greatest length on the anterior end, and a

similar one, but less strongly marked, on the posterior side. There is no

perceptible difference in form between the right and left valves, each showing

the features abont equally developed. No appearance of striations radiating

from the ocular tubercle can be detected, either on the internal casts or in the

matrices ; still the nature of the rock in which they are imbedded is such that

very obscure markings would scarcely be preserved.

This species differs from Leperditia alia Conrad, of the same

formation, in its larger size, and in the larger and more distinct

eye-tubercle, as well as in its slightly different position; but most

distinctly in the sub-angular ridge-like node, and greater convexity

of the lower border of the valves. This projecting node being

situated near the lower margin, and also being the most prominent

point of the valve, causes the rock to adhere to the more abrupt

sides when fractured, and gives to the valves as they appear upon

the fractured surface a very decidedly triangular aspect, entirely

unknown in L. alta.

Formation and Locality.—In the hydraulic limestone of the

Lower Helderberg group, at Greenfield, Ohio, where it occurs in

great numbers, forming distinct layers through the rock, as does

Receptaculites devonicus Whitf., An. N. Y. Acad. Sci., March, 1882, p. 198.

A very decidedly marked and characteristic specimen of the genus

Receptaculites, DeFrance, has been obtained from the limestones

of the Upper Helderberg group, by Mr. Ed. Hyatt, of the Ohio

State University, from a quarry at Fishinger’s mills, about eleven

miles north of Columbus, Ohio. The specimen is about two and

a half inches in diameter, is broadly concave across the disk, and

slightly recurved at the outer margin. The concentric lines of pores

or cells are strongly marked, and increase rapidly in size as they

recede from the centre of the disk, but the surface has been so much

weathered that the grooves left by the removal of the stolons at the

foot of the cells are not distinguishable, so that the entire specific

characters are not recognized; enough, however, remains to show

the general form and proportions. It has much the appearance of

specimens of a corresponding size of &. Oweni Hall, from the lead-

bearing limestones of the West, both in its general form and in

the concavity of the disk, as well as in the proportions and rate of

increase of the cell-openings as seen exposed on the surface of the

limestone.

The occurrence of a species of this genus at this horizon, is a

rather unexpected feature in its history. The highest horizon of

its occurrence hitherto recorded, is in the shaly limestone of the

Lower Helderberg group of New York, from which the type of

the species Receptaculites infundibuliformis ( Coscinium infundi-

buliformis Eaton, Geol. Text-book, 2d ed., 1833, p. 132, fol. 5, figs.

Corallum compound, growing in irregular or more or less hemispherical

masses of several inches in diameter, which are formed of a large number of

closely aggregated polygonal cell-tubes or polyps, of rather small size, divided

by intercellular walls of considerable thickness, as in most forms of the com-

pound Cyathophyliide. Full-grown polyps, measuring abort half an inch in

diameter, but usually somewhat smaller; the prevailing size being about

three-eighths of an inch. Calyces deep, abruptly declining from the inter-

cellular walls to a depth nearly equalling the transverse diameter. Longitu-

dinal septa or rays well developed, extending about one-third, or less of the

diameter of the tube from the outer wall, and averaging about forty in number

in adult individuals; some containing thirty-six, and one large one counted

gives forty-two. Crest of the rays strongly denticulate, the denticles being

thickened and knot-like at their junction with the rays. Central chamber

within the limits of the longitudinal rays, equal to one-third of the entire

diameter of the polyp, and divided by numerous distinct transverse tabule,

which are variously bent or interrupted by contact with the adjoining ones,

leaving irregular cavities of considerable size between them. Interseptal spaces

occupied by a series of horizontal plates, which originate at the outer wall,

and extend upward and inward with increased growth to the edge of the rays,

where they form the denticulation of the crest. Between the latter plates, the

spaces are occupied by the smaller irregular vesicular structure.

The species, in its general features, resembles Cyathophyllum

rugosum Hall, sp., from this formation, and may be easily mistaken

for that one, in obscure or imperfect specimens; but where the

internal structure is observable, especially in longitudinal sections

of the polyps, can be very readily distinguished by the large central

space in each polyp, and by the strongly developed transverse

tabule ; also by the rays not extending to the centre, as in that

species and in those of the genus Acervularia. When the coral is

weathered, or the substance becomes chalky, so that the polyps are

readily separable from each other longitudinally, the appearance

very closely resembles that of Cyathophyllum rugosum when in a

similar condition, but the interruption of the rays before reaching

the centre, and the great extent of the tabule, will then serve to

distinguish them.

Shell below a medium size, semi-circular or semi-ovate in outline, with a

straight hinge-line of variable length ; the lateral and front margins are some-

what regularly rounded and, in a profile view, irregularly bi-convex. Ventral

valve depressed convex, with a more or less elevated and projecting but twisted

or distorted beak, overhanging a nearly vertical cardinal area of irregular form

and width, which is divided in the middle by a narrowly triangular convex

deltidium. The dorsal valve is almost regularly semi-circular, very depressed

convex, with a slightly more prominent umbo, and is destitute of cardinal

area. Surface of the valves marked by from twenty-two to twenty-four strong,

rather sharply elevated, radiating plications, which are entirely simple, and

separated by broad, concave interspaces. The shell is also further marked

by fine, regular, concentric strie of growth, which arch backward in crossing

the radii, and may have been sub-lamellose on the external surface, but the

examples seen are all exfoliated.

The species is of a somewhat unusual type, especially in Devonian

rocks. The dorsal valve seen alone presents so much the appear-

ance of a strongly-marked Aviculopecten, that when first observed

it was thought to belong to that genus; but the ventral valve,

similarly marked, and possessing the characteristically twisted car-

dinal area and beak with its covered fissure, at once indicates its

true position, It is entirely unlike any species hitherto described

Rhynchonella raricosta Whitf., Ann. N. Y. Acad. Sci., March, 1882, p. 201.

Shell of moderate size, and somewhat transversely sub-triangular in out-

line, when seen upon the ventral side. Ventral valve flattened and very

shallow, with a short, obtuse, and not at all incurved beak; cardinal slopes

incurved, and the margins straight from the beak to near the point of greatest

width of the valve, the angle of divergence being nearly or quite 120 degrees.

Front of the valve broadly curved, and marked by several deep indentations

corresponding to the number of plications marking the surface. Middle of the

valve marked by a broad, shallow, slightly angular mesial sinus, which is

more than one-third as wide at the front of the valve as the length from beak

to base. Surface of the valve marked, on each side of the sinus, by two low,

angular, but distinct plications, besides those bordering the sinus; no other

markings are traceable on the surface of the shell. The margin of the valve

between the plications is extended, forming rounded projections similar to that

of the mesial sinus, and probably corresponding to low rounded plications

which have characterized the dorsal valve, which has not been observed.

The broad sub-triangular form of the shell, with the shallow ven-

tral valve and the small number of low, angular plications, will

readily distinguish this from any species hitherto known. ‘There

may possibly be some doubt as to the generic reference of the

species ; but this cannot be positively determined until more perfect

individuals are obtained.

the distance from the anterior to the posterior margins across the point of

greatest diameter, only a trifle over one inch; the depth of the valve being

nearly half an inch. Form of the shell elongate triangular-ovate, rather

acutely pointed at the beak, which is small and incurved ; anterior, or byssal,

margin straight and absolutely vertical in the example mentioned ; basal

margin broadly rounded from the anterior line nearly to the point of greatest

length of the valve, where it is more rapidly curved, and finally passes abruptly

into the rapidly ascending posterior margin ; the lower part of which is nearly

parallel to the anterior side, but above inclines more rapidly toward the short

and very oblique hinge-line. The surface of the valve is most elevated along

the anterior umbonal ridge, where it is at right angles to the anterior surface, ~

but slopes gently backward for two-thirds of the distance toward the posterior

margin, and on the other third much more abruptly. Near the beak, the sur-

face rounds rapidly from the anterior ridge to the posterior border. Surface of

the shell marked by numerous concentric ridges, parallel to the margin of the

valve, many of which are strongly marked and form varices of growth. On

the anterior surface, these varices and the concentric strie are well marked.

Cardinal area not observed.

The example used is a right valve, and bears evidence in its cha-

racters of being an adult shell. It is associated in the same layers

of cherty material with JL ponderosa, H. & W. (Prelim. Notice

Lamell. Shells, ete., p. 21), but may be readily distinguished by the

vertical anterior surface and the angular umbonal ridge. From the

young of that species, it is readily distinguished by these characters,

as those are distinctly round and ventricose. The only known

species approaching this in the angularity of the ridge, is JZ. atten-

uata, H. & W., of the Chemung group; but this is quite distinct

in other respects.

Platyceras squalodens Whitf., Ann. N. Y. Acad. Sci., March, 1882, p. 202.

Shell small, sharply conical when viewed in a lateral direction, with the

apex gently curved anteriorly ; but in a posterior view, the form is narrowly

lanceolate, with the dorsal portion rising into a thin, sharp crest or ridge;

anterior side rounded and the anterior slope concave. Aperture narowly ovate,

rounded on the anterior side, widest just above the middle, and extending

backward into a narrow point. Surface of the shell marked by fine, hair-like,

concentric lines of growth parallel to the margin of the aperture, which is a

little bent down anteriorly and posteriorly, and also by a rather faintly marked, *

but still distinct suleus, which passes from the apex on the left anterior slope,

and over which the striz are slightly undulated, indicating a slight notch in

the margin at this point.

In the narrow and curved lanceolate form of the shell, this species

differs very materially from any of the numerous species of this

very monotonous genus, and may be readily distinguished by the

sharp dorsal ridge.

Genus DENTALIUM Linneus.

Dentalium Martini.

PuatE VII, fig. 10.

Dentalium Martini Whitf., Ann. N. Y. Acad. Sci., March, 1882, p. 203.

Shell somewhat larger than medium size, rather rapidly expanding from

the apex to the aperture for a species of this genus, and moderately curving

throughout the length ; cylindrico-conical in form, and circular in a transverse

section. Surface marked only by encircling strie, which form rather broad

undulations on the shell, and are strongly arched forward on the inner side of

the curvature, showing that the lip of the shell has been somewhat extended

on this side of the aperture. Shell-substance thick.

The species attains a rather large size, and expands more rapidly

than most species of the genus, reaching a diameter of one-fourth

of an inch in a length of less than two inches. The curvature is

also considerable, being deflected fully an eighth of an inch from a

straight line within the length of the specimen when tested on the

inner face. There is no species of similar character from rocks of

Devonian age, so far as can be ascertained. On some of the inter-

nal casts, there occurs a longitudinal ridge, as if there had been a

slit or interruption of some kind at that point,which gives rise to a

supposition that it may have belonged to the genus Coleoprion

Sandberger, though no positive interruption of the striz of the sur-

face is seen on any specimen examined. This fact may suggest its

belonging to the recently formed genus Coleolus Hall; but its per-

fect resemblance to Dentalium more strongly indicates its affinities

as in that relation, rather than with the Pteropoda. Nor does there

appear any sufficient reason among the species referred to Coleolus

by its author, for a generic separation from Dentalium, other than

their more strictly straight form. But there are straight or nearly

straight Dentalia, and also curved forms which he has referred to

the new genus. The generic feature ‘“ shells thick” would also be

opposed to pteropodous affinities. In its more rapid taper and

greater curvature, it is sufficiently distinct from described forms of

that genus,

Macrocheilus priscus.

Macrocheilus priscus Whitf., Ann. N. Y. Acad. Sci., March, 1882, p, 204.

Shell small and very ventricose, the height but little greater than the dia-

meter of the body volution ; the former in the figured example being three-

eighths of an inch, and the latter only about one-sixteenth of an inch less.

Shell composed of about four volutions, which are very ventricose and rapidly

increase in diameter, the last one forming the great bulk of the shell, equalling

fully two-thirds of the entire height. Suture-line distinct, but not strongly

marked. Apical angle about eighty degrees. Aperture somewhat semilunate,

strongly modified on the inner side by the body of the preceding volution,

which occupies fully one-half its height. Columella strong, straight and

rounded, and the twisted ridge obsolete. Surface of the shell apparently

smooth ; at least no strie are perceptible.

This pretty little species reminds one strongly of IZ. ventricosus

Hall, from the Coal-measures, but is somewhat shorter in the spire,

although resembling it in most other respects. The substance of

the shell is soft and chalky, and might not retain minute surface

Puate VII, fig. 5.

Loxonema parvulum Whitf., Ann. N. Y. Acad. Sci., March, 1882, p. 204.

Shell minute, scarcely exceeding a fourth of an inch in length, and propor-

tionally slender, with a rapidly ascending spire, which is slightly more rapidly

tapering in the upper than in the lower part. Volutions six or six and a half,

moderately convex on the outer surface, and more strongly rounded on the

lower part of the exposed portion than on the upper; suture-line distinct, but

not margined by a flattening of the upper edge of the succeeding volution.

Aperture elongate, slightly angular at the base, and pointed above. Surface

of the volutions marked by a large number of distinct vertical strie, which

are more numerous and slightly finer on the body volution than above, and are

‘so nearly destitute of sigmoid curvature as to appear vertical until closely ex-

amined.

The small size of the shell, the nearly vertical lines, and the un-

equally expanding volutions, are distinguishing features; the latter

character, however, appears to vary a little in degree on some of

the specimens. It will be readily distinguished from the young

shells of LZ. Hamiltoniz, which occurs in the same rock, by the

number of volutions and the slender form.

an inch at the lower extremity. Section circular ; tube moderately increasing

in diameter with increased length, slightly curved throughout, and marked by

regular encircling annulations, which are elevated, round on the crest, sepa-

rated by deeply concave interspaces, which regularly increase in distance and

also in strength from below upwards. Those of the lower part where the shell

is uncompressed and is half an inch in diameter, are about one-tenth of an inch

distant from each other ; and at the upper end where the diameter is about one

and three-fourths of an inch are about three-eighths of an inch from crest to

crest. Surface of the shell marked by fine, closely arranged and sharply ele-

vated concentric striz, and also by longitudinal strie of similar character, but

more or less alternating in strength, the two sets giving a finely cancellated

structure just discernable to the unassisted eye. Septa very deeply concave

and regularly curved, uniting with the shell a little above the crest of each

annulation. Siphuncle small and centrally situated.

The species is of the ordinary annulated type differing from other

species of the group only in the strength and comparative distance

of the annulations; in the rate of increase in diameter, and in the

nature of the surface markings. The shell, like many of the annu-

lated forms of any considerable size from the Upper Helderberg

and Hamilton groups, shows a slight curvature of the tube, a little

more perceptible in the lower part than above. The Ohio specimens

correspond more nearly to the one from the Hamilton group of

N. Y., figured by Prof. Hall (Pal. N. Y., Illust. Dev. Foss., Pl. 43,

fig. 14), in the rate of increase in the diameter, and in the form and

relative strength of the annulations than with the original speci-

mens to which the name was first applied, or to most of those

figured under the same name on the same plate. The specimen from

Ohio figured on Pl. 41, fig. 9, Illust. Dev. Foss., Pal. N. Y., under

the name O. Thoas, is identical with the one here described, but

does not retain the shell nor show surface markings, but corresponds

in the form of the annulations and in its slight curvature and rate

of increase in diameter, in which particulars it differs materially

from those from New York, given on the same plate. It is barely

possible the Ohio specimens may represent a species distinct from

any of those from New York, but it seems totally impossible to de-

tect characters sufficient to distinguish it as such. O. subulatum

Hall, from the Marcellus shell is a very closely allied if not identical

form.

Genus TREMATOCERAS Whitf.

Ann. N. Y. Acad. Sci., March, 1882, p. 205.

A straight, obconical, cephalopodous shell, presenting the characteristics of

an Orthoceras, so far as the appearance of the tube, septa and siphuncle is con-

cerned ; but with the additional feature of a line of elongated, raised tubercles

along one side of the shell, which have formed perforations at certain stages of

growth, probably confined to the outer chamber as openings, which were closed

as the animal extended the shell, and before the septa opposite them were

formed. Type, 7’. Ohioense.

The shell for which the above generic name is proposed offers an

entirely novel feature among the Orthoceratide. The line of nodes

seen on the cast of the shell is entirely different from anything per-

taining to the ornamentation of the shell, and presents the same

appearance as would the partially filled perforations of a Haliotis,

or like those shown on the back of species of Bucaniza, and those

on which the genus Tremanotus was founded; neither is it a fea-

ture at all dependent upon the position of the siphon or directly

connected with it; for in the specimen used the siphon is slightly

excentric, on the opposite side of the tube from the nodes. Its posi-

tion would thus indicate that it was a feature pertaining to the dor-

sal lip of the shell, corresponding to the sinus seen in the lip of many

other genera. Taking this view of it, it would appear to indicate

the existence of a deep, narrow notch, with raised margins, in the

lip of the shell at stated periods, beyond which the shell was again

united for a time, leaving a perforation to be closed by a deposit of

shell from the mantle as it approached the lower part of the chamber

of habitation. Many species of Orthoceras have been observed,

having a raised line, or rather markings, along the dorsal side; but

none, so far as I am aware, presenting these evidences of a series

of separate openings, which I consider a feature worthy of generic

distinction.

and at every second in the upper part of the specimen.

Gomphoceras Hyatti.

PuateE VIII, fig. 1, and Puate V, fig. 1.

Gomphocerus Hyattti Whitf., Ann. N. Y. Acad. Sci., March, 1882, p. 206.

Shell large and robust, slightly arcuate throughout, but more strongly

curved below than in the upper part ; somewhat rapidly expanding from below

upward to near the middle of the outer chamber, where it is suddenly con-

tracted to the aperture, and on the lateral margins again slightly expanding.

The rate of increase in diameter, as compared with the increased length, is

about as one and two, when measured on the inside curvature. Transverse

section of the shell obtusely subtriangular, flattened or but slightly convex on

the inner surface, rounded on the lateral surfaces, and obtusely rounded on the

back; the dorso-ventral and lateral diameters are about as four and five, and

the triangular form is more perceptible in the earlier stages of growth, owing

to the greater convexity of the inner face in the upper portion and on the outer

chamber. Outer chamber comparatively short, being about two-thirds as high

as wide. Aperture large, irregularly tri-lobed, straight on the inner face, and

about four-fifths as wide as the entire width of the shell, and apparently about

two-thirds as wide in a dorso-ventral direction as laterally. The exact form

of the aperture on the outer side cannot be ascertained, owing to the imperfec-

tion of the specimen in this part. Septa moderately concave, very closely

arranged in the lower part, but more distantly disposed above; the rate of in-

crease in distance somewhat gradual to near the upper portion, where two or

three of the septa are slightly more crowded. In the more distant portions,

three chambers occupy the space of one inch, but in the lower part of the

specimen, where the transverse diameter is a little more than one and a half

inches, they are less than one-twelfth of an inch apart. Siphuncle of moderate

size and sub-centrally situated. Surface of the shell unknown.

The specimen from which the description is taken is an internal

cast, not retaining any portion of the shelly structure; but it ap-

pears to have been destitute of strong surface markings. It measures

about seven inches in length by nearly four inches in transverse

diameter at the widest part, which is near the lower part of the

outer chamber. The lower end is imperfect, and measures one and

a half inches in transverse diameter. It is with some hesitation

that I place the species under the genus Gomphoceras, owing to the

strong curvature of the shell and the structure of the aperture,

which is reversed in its relation to the curvature of the shell as

compared with most species of the genus; the widest portion being’

on the inside curvature, instead of on the outer side. The general

triangular or trilobed form of the aperture, together with the greater

lateral diameter, would seem to overbalance the fact of the curva-

ture.

Gomphoceras amphora.

PuaTE VII, fig. 9.

Gomphoceras amphora Whitf., Ann. N. Y. Acad. Sci., March, 1882, p. 207.

Shell of large size, elongate-ovate or short sub-fusiform, somewhat rapidly

expanding from below upward to within a short distance of the base of the

outer chamber; from which point it again contracts more rapidly to about

one-half the height of the outer chamber, and is then drawn out into a narrow

neck, resembling the neck of a bottle, of a width but little exceeding one-third

of the diameter of the larger portion of the shell. Aperture not distinctly

traced, but on the side figured, there is an appearance of a deep, rather narrow

sinus, extending nearly one-half the depth of the outer chamber. The shell

bears the appearance, also, of having been curved, as indicated principally by

the obliquity of the septa, which are numerous, rather deeply concave, and

arrauged at a distance of about one-fourth of an inch in the largest part of the

specimen, and decreasing in distance below and above; while near the base of

the outer chamber there are about six septa closely crowded together. Position

of the siphuncle not determined.

The species resembles G. eximium Hall, of the same formation,

in the lower part of its length, although more rapidly expanding,

but in the upper part, and especially near the aperture, differs en-

tirely from any other species known.

Gomphoceras Sciotense Whitf., Ann. N. Y. Acad. Sci., March, 1882, p. 208.

Shell of medium size or smaller, short obconical in form, or rapidly expand-

ing from the apex upward; slightly flattened in a dorso-ventral direction,

giving a broadly oval transverse section, which is a little more flattened on the

dorsal than on the opposite side, in the more perfect specimen, but may not be

constantly so in all individuals. Septa shallow, arranged at nearly equal dis-

tances from each other in the larger parts, and numbering about seven in an

inch, except near the outer chamber, where there are usually one or two more

closely arranged. The outer chamber is proportionally short, and rapidly con-

tracted in the upper part to about one-half the diameter below, to form the

transversely sub-triangular or obscurely trilobed aperture, which is rounded

at the lateral extremities, straightened on the dorsal side, and provided with a

moderately deep but rather narrow sinus on the ventral margin. Siphuncle

proportionally small, and situated close to the dorsal side.

Only two individuals have thus far been observed, and these

show some slight variation in the form of the transverse section

and in the proportional length of the outer chamber; the one re-

taining the chambers being shorter above, and more flattened on the

dorsal side than the other. In this specimen, the septa are some-

what obliquely arranged, being highest on the dorsal side, which

may, however, be owing to oblique compression in the matrix. The

individuals, being both internal casts, have afforded no opportunity

of observing the surface structure.

Shell of medium size, somewhat moderately expanding in its upward growth

to the base of the outer chamber, from which point it again contracts to the

aperture; the increase not always regular, but in some individuals more

abruptly expanding above than below. Shell slightly curving throughout its

length, appearing less arcuate in the upper portion, owing to the contraction

of the outer chamber toward the aperture. Transverse section oval, widest

in a lateral direction, and with the inner surface much less arcuate than the

outer or dorsal surface. Outer chamber proportionally short, the length not

exceeding the dorso-ventral diameter of the lower end; margin simple, so far

as can be determined from any of the specimens, showing only a broad, shallow

sinuosity on each side. Septa somewhat closely arranged and deeply concave,

but slightly increasing in distance in the upper part, the average length of

the chambers being about one-tenth of an inch, but somewhat more crowded

just below the outer one. Siphuncle of moderate size, situated a little within

the dorsal surface, and very slightly expanded within the chambers. Surface

of the shell marked only by transverse lines of growth parallel to the margin

of the aperture.

The shells are moderately abundant, and show slight variations

in form among individuals, especially in the rate of increase in

dimensions or in the regularity of the expansion, as well as in the

comparative distance between the septa; a single individual show-

ing a much greater distance between them in the upper part of its

length. The shell would probably be considered by some as belong-

ing to the genus Oncoceras, as the decrease in diameter in the upper

part of the outer chamber gives to the shell, below, the peculiar

bulging appearance supposed to be characteristic of that genus;

but the transverse form and elliptical. section, together with the

form of the siphuncle and other features, present characters com-

mon to the genus Cyrtoceras. It is most nearly related, in general

form, to C. Conradi Hall, from the Marcellus shales of New York

but attains a much greater size, has a shorter outer chamber, and

is destitute of the small lip-like sinus on the ventral side, as seen

in that one. The upper portion of Gomphoceras oviforme Hall,

from the limestone of the Marcellus shale, bears considerable resem-

blance, except in the closing of the aperture, which constitutes a

generic difference.

in a transverse section, being a very little greater in the lateral direction than

in the dorso-ventral, and the back of the volution barely perceptibly flattened

on the outer portion of the larger one, but not perceptibly so on the inner

portions. Septa deeply concave and distantly arranged; the chambers mea-

suring about half an inch each, on the outer two-thirds of the body volution

of a specimen where the vertical, or largest, diameter of the disk is five inches.

Position of the siphuncle not absolutely determined. Surface of the shell

unknown.

All the individuals of this species observed are internal casts, and

occur in a rather rotten limestone, under conditions very unfavor-

able for the preservation of the shelly substance; consequently

the surface characters have not been observed. It is an abundant

species, but owing to the conditions of preservation, is not often

found in collections. It will be readily distinguished from the

other described species by the closely coiled volutions and the

nearly circular section. It is perhaps more nearly related to G.

cyclops Hall, 15th Rept. N. Y. State Cab. Nat. Hist., than to any

other described species; but it differs from that one in its smaller

size, and more rapidly increasing as well as more closely coiled

volutions, and does not appear to have been provided with the

broadly expanding and foliated varices which are so characteristic

of that species. It might be objected, that as the shell of this

species is unknown, the determination of the absence of these

foliated expansions is not well authenticated; but it may be

answered, that as the two species are associated in the same layers

in the quarries where they are both rather common, if they were

really one and the same, the shell would be preserved on these as

well as on the G. cyclops, and the expansions readily detected.

Shell small, compactly coiled, and consisting, in the specimen used, of a

little more than two volutions, which increase rather rapidly in diameter with

increased age; they are somewhat wider transversely than in a dorso-ventral

direction, and are slightly triangularly elliptical in a transverse section; the

greatest transverse diameter being very slightly outside of the middle of the

dorso-ventral diameter. The inner one and a half coils are smooth on the

exterior, but the outer volution, for a little more than the larger half, is

ornamented by a single series of comparatively large, transverse, triangularly

elliptical nodes on each lateral surface, having the angular side of the node

placed anteriorly and the opposite side nearly straight. The nodes are placed

at distances from each other about equal to one-half the dorso-ventral diameter

of the tube at the node indicated. The septa are not clearly defined and can-

not be given with certainty; but they appear to be distantly placed on the

inner portions of the shell, while on the nodose portion they seem to be placed

at about half the distance of the nodes apart. The siphuncle has not been

observed. The surface of the shell, as seen on a fragment of the substance

remaining on the dorsum of the outer volution, is marked with rather close,

distinct, revolving lines or ridges, crossed by more closely arranged transverse

lines, which make a shallow retral bend in crossing the back of the shell.

The specimen is probably an immature shell, but is a distinctly

marked species, differing strongly in its form and nodose character

from any of those associated with it. It most nearly resembles G.

(Hercoceras?) paucinodus Hall, from the Upper Helderberg group

of New York (see Illust. Dev. Foss., pl. 55, figs. 1 and 2), but is

less distinctly triangular in a transverse section, that one being

widest near the outer portion of the volution, with a nearly regular

sloping surface on the side of the whorl to its junction with the

preceding one, while this species is rounded. The form of the nodes

is also different—those being situated near the dorsal margin. The

triangular form of these nodes is peculiar in having the two short

sides of the triangle directed forward. It also differs in having a

greater number of volutions for a given diameter.

NOTE ON THE MARCELLUS SHALE AND OTHER MEMBERS OF

THE HAMILTON GROUP IN OHIO, AS DETERMINED FROM

PALEONTOLOGICAL EVIDENCE,

During the early summer of 1878, President Edward Orton wrote,

asking if I could spend a few days with him in central and southern

Ohio, in an effort to ascertain from paleontological evidence, the

true horizon of certain layers of rock which had been somewhat of

a difficulty to him; and in the month of August I spent several

days with him for that purpose. While making these somewhat

hurried observations at a locality about six miles N. W. of Colum-

bus, in Perry Township, on the east bank of the Scioto River, we

accidentally discovered a thin bed of dark brown shale, somewhat

fissile and bituminous in character, in what Prof. Orton had con-

sidered as a representative of the Delaware limestone of Delaware,

Ohio. The peculiar texture of the shales, occurring where I had

expected only a light-colored limestone, excited my interest; and

after a few minutes’ examination, I discovered that they contain

numerous flattened shells of Letorhynchus limitaris, Vanuxem. I

also obtained from them two specimens of Discina minuta, and ex-

amples of Lingula Manni Hall; the two former being well-known

and characteristic forms of the Marcellus shales of New York. On

examination, we found that these shells, especially the Leiorhyn-

chus, extended through a thickness of several feet of the rock, and

that the peculiar bituminous character of the shale accompanied

them, but with intercalations of thin layers of less bituminous and

lighter-colored limestones. Subsequently, at a point nearly oppo-

site Dublin, Ohio, some miles north of the above-mentioned locality,

the same shale was again recognized in a corresponding horizon,

accompanied by the same species, the Leiorhynchus being quite

numerous. At a subsequent visit, Mr. Edward Hyatt obtained

Discina Lodensis Hall, another New York Marcellus species. At

this second locality, immediately above the shale, and while the

limestone layers retain much of the bituminous character, the layers

become thicker and more calcareous, and their surfaces are covered

with the shells of Spirifera gregaria Clapp, and Tentaculites

scalarifornmis Hall, both of which are likewise common in the blue

limestone layers at Delaware, Ohio.

A section of the rocks at the first-mentioned locality, six miles

N. W. of Columbus, on the east bank of the Scioto, subsequently

furnished by Prof. Orton, is as follows :—

The lower bed, No. 1 of section, is a heavy-bedded limestone

about thirty feet thick, representing the Columbus quarries, includ-

ing the coral beds and those containing the large cephalopods.

(Lower Corniferous of the Ohio Geol. Rept.)

No, 2, a thin layer of limestone, four to six inches thick densely

filled with teeth, plates and bones of fishes, locally known as the

“* Bone-bed.”’

No. 38, about thirty feet of thin-bedded shaly limestone, the

‘Delaware bed” of Prof. Orton. The upper part of this is sup-

posed to represent the beds of similar character at Delaware, Ohio,

which contain the large fish-remains.

No. 4, about fifteen feet of bluish, somewhat marly shales, the

“Olentangy shales’ of N. H. Winchell. This is followed above by

the Huron shales, the supposed equivalents of the Genesee slates

and Portage shales of New York.

Near the lower part of No. 3, only a few feet above the “ Bone-

bed,” occurs the dark brown shale in question, with the peculiar

fossils, which I have no hesitation in pronouncing the equivalent of

the Marcellus shales of New York. Admitting this—and there

certainly appears to be no alternative—the rocks found above this

limit should represent the Hamilton group of the New York sys-

tem; and we ought to find some fossils here, characteristic of that

formation, which would not pass below this line. To ascertain if

this was so, I requested Mr. Edward Hyatt, who has collected care-

fully the fossils around Columbus, to furnish me a list’ of the species

known, with their horizons indicated; and also requested the use

of specimens of species not known to occur below the horizon of

the ‘ Bone-bed,” that being the most easily recognized limit, and

the one most generally studied in connection with the vertical dis-

tribution, Contrary to my expectations, the species yet known not

to pass below the ‘‘ Bone-bed” are very few. These, with the ex-

ception of the Tentaculites scalariformis, have been illustrated on

Plate VII, and are, with two exceptions, known Marcellus and

Hamilton types, one being a new species, and the other (Spirifera

Maia Bill.), occurring in the Upper Helderberg limestone in Canada.

The examination of the upper layers for characteristic fossils was

not carried far enough to make it perfect, owing to Mr. Hyatt’s

absence from Columbus; but the few forms found above these bitu-

minous layers will readily be recognized as characteristic of the

Hamilton group, and warrant one in considering the Black shales

and other beds coming above these thin limestones in central Obio,

as equivalent to the Genesee slates and succeeding formations of

New York."

The following lists, prepared by E. and H. Hyatt, of Columbus,

Ohio, are from the limestones within 24 miles of that place. Those

of the first list are from below the horizon of the ‘‘ Bone-bed,”’ and

the next from above; Strophomena rhomboidalis being the only

species fully recognized from both horizons. All species have been

collected by them from known horizons, or have been seen from the

beds by myself.

1 Since writing the above remarks, Vol. V of the Palzont. of New York has

been published. In it the author has, on p. 139, some remarks on the lime-

stones at the Falls of the Ohio, and their relations to the Hamilton group of

New York. After showing that the Hydraulic-cement beds of the Falls of the

Ohio are the equivalents of the Hamilton group of New York (which had already

been stated in the Geol. Rept. Ind., 1875, pp. 147, 148, and also shown in sec-

tions on page 157), the author remarks, ‘‘In the State of Ohio, similar condi-

tions may be inferred, from the fact that certain known species of Hamilton

fossils are published in the Ohio Geological Reports as from the Corniferous

group.’”’? At the meeting of the Am. Assoc. for the Advancement of Science, at

Saratoga, August, 1879 (see Proc. A. A. A. Sci., vol. xxviii, p. 297), Tread a

notice of the occurrence in Ohio of rocks representing the Marcellus shales of

New York, embracing most of the substance of this note, and in which it was

shown that a considerable thickness of the limestones previously recognized as

** Corniferous’’ in Ohio, were above the horizon of the beds which I had recog-

nized, from paleontological and lithological evidence, as of the age of the

Marcellus shale, and would be of necessity equivalents of the Hamilton group.

This was in August, 1879. The volume above-mentioned is dated, in the letter

of transmissal, Dec. 15, 1879.

RECOGNIZED SPECIES FROM THE MARCELLUS SHALES OF OHIO.

MOLLUSCOIDEA.

BRACHIOPODA.

Genus LINGULA Brug.

Lingula Manni.

PuateE XI, figs. 1 and 2.

Lingula Manni Hall.; 16th Rept. State Cab. N. Y., p. 24; Pal. N. Y., vol. 4,

No. 6, pl. 2, fig. 3.

Shell of medium size, longitudinally subovate, somewhat more than half as

wide as long, very obtusely pointed at the upper end, with subparallel lateral

margins, and often rather squarely truncate in front, with rounded basal angles.

Substance of the shell thin and polished, with irregular concentric lines of

growth which do not produce any marked surface character. Interior of the

valves sometimes characterized by a thin, hair-like, median ridge, which

extends to below the middle of the valve, leaving a distinct median depression

on the cast where the substance of the shell has been removed.

The specimens of this species are usually about three-fourths of

an inch in length by a little less than half an inch in width. They

vary considerable in outline, the variation being principally in the

form of the front, some of them being much more round on the

front margin than others, or than the type specimens. This varia-

tion also causes a difference in the form of the lateral margins pro-

ducing a more rounded or oval form, and giving the shells an ap-

pearance approaching that of Z. Delia Hall, Pal. N. Y., vol. iv, p.

12, pl. 2, fig. 9. The two forms are associated in the shales and

can scarcely be considered as distinct species. Many of the speci-

mens are so distinctly like Z. Manni, that it seems impossible the

others having so slight a difference in form could be distinct, that I

have not thought it advisable to attempt their separation.

Lingula ligea ?

PuateE XI, figs. 3 and 4.

? Lingula ligea Hall; Pal. N. Y., vol. 4, part 1, p. 7, pl. 1, fig. 2.

Shell elongate elliptical in general outline, being about twice as long as

wide, rounded on the anterior end, and slightly more pointed at the beak in

full grown forms ; but in young or partly grown shells the extremities appear

nearly equal. Valves moderately convex, and sometimes a very little flattened

along the middle. Surface marked by fine concentric lines of growth.

The examples referred with some slight doubt to this species are

quite numerous in the thin bedded layers of bituminous limestones

from above the ‘‘ Bone-bed,” at Smith and Price’s quarries, near

Columbus, Ohio. The young shells have much the appearance of

L. spatulata Hall, but when fully grown are almost exactly of the

character of LZ. ligera.

Genus DISCINA Lamarck.

Discina minuta.

PuateE XI, figs. 5 and 6.

Orbicula minuta Hall, Geol. Rept. 4th Dist. N. Y., p. 180.

Discina minuta Hall, Pal. N. Y., vol. 4, p. 16, pl. 1, fig. 16.

Shell minute, subcireular. Dorsal valve moderately convex or flattened as

occurring in the shales, the apex situated a little nearest the posterior margin,

often about one-third of the diameter from the border, pointed and directed

toward the posterior or peduncular margin. Ventral valve not observed. Sur-

face of the shell marked only by closely arranged, very fine concentric strie.

The shells of this species usually occur of about three-sixteenths

of an inch in diameter, and are usually very much flattened by

compression in the shales. They closely resemble those from the

black Marcellus shales of New York, but lack that convexity and

finely polished surface usually present on the Avon specimens.

rowed toward the peduncular margin, and broadest forward of the

middle. Foramen comparatively small, narrowly elliptical, not ex-

tending quite to the margin, the inner end not reaching to the centre

of the disk; the point of origin on the valve being slightly excen-

tric. Surface marked by fine, not closely arranged, elevated, con-

centric lines.

The specimen described and figured very closely resembles the

New York species above cited; so nearly so in fact as to preclude

the possibility of detecting specific differences. The specimens from

New York differ greatly among themselves in the general form and

outline of the valves; so that on this character alone it would not

be safe to rely ; and the general features of the shell, so far as can

be determined from a single valve, are the same in both cases.

Formation and Locality.—In the brown shales at the top of the

Upper Helderberg limestone near Dublin, Ohio.

Genus CHONETES Fischer.

Chonetes scitula.

PuaTeE XI, fig. 10.

Chonetes scitula Hall, Pal. N. Y., vol. 4, pt. 1, p. 130, pl. 21, fig. 4.

Shell small and semicircular in ontline, or in some cases semi-ovate being a

little more than half of a circle. Hinge-line as long or a little longer than the

shell below, and but slightly mucronate at the extremities. Ventral valve

nearly equally convex or a little depressed just within the cardinal extremi-

ties. Dorsal valve flattened or slightly concave. Surface marked with about

sixty, fine, even strie in the larger specimens, as counted on the ventral valve,

and the hinge-line bears three short spines on each side of the beak.

The specimens being in limestone are all much exfoliated, so that

the surface strive are not distinctly shown toward the cardinal bor-

ders. The shells are perhaps a little longer than the more typical

forms of C. scitula as they occur in the Hamilton shales near

Cayuga Lake, N. Y., and are somewhat intermediate in this respect

between those and C. Yandelli Hall, from the hydraulic limestones

from near Louisville, Ky.

Formation and Locality.—In thin-bedded bituminous limestones

of the Marcellus shale, above the ‘‘ Bone-bed” at Smith and Price’s

quarries, near Columbus, Ohio.

Chonetes reversa.

Pirate XI, figs. 8 and 9.

Chonetes reversa Whitf., Ann. N. Y. Acad. Sci., 1882, 213.

Shell of about a medium size, semicircular in outline, with a long straight

hinge-line exceeding the width of the shell below. Valves resupinate, or

reversed in their curvature; the ventral being very slightly convex in the

earlier stages of growth, and subsequently recurved so as to appear concave ;

the entire deflection from a plaue being very little, so that the general appear-

ance of this valve may be said to be nearly flat. Area linear. Hinge-line

ornamented by four, long, very slender spines on each side of the centre, which

are projected from the hinge-line at an angle of about 65 degrees, measured

on the outside; or 115 degrees as counted on the inside of the spine. Surface

of the ventral valve marked by exceedingly fine strie, which are slightly

alternating in size; there being from two to five finer ones between the coarser

kind. Interior of the valve characterized by fine pustules, arranged in indis-

tinct lines, presenting the usual characteristics of the genus. Dorsal valve

not positively known; but there is associated with it, in the same layers, a

slightly convex valve with similar striz, but more distinctly alternating,

which may possibly represent this valve. Its form is similar, and the con-

vexity correspondingly great.

This species is peculiar in its resupinate character, so far as the

genus is known in American Devonian rocks, and this character,

together with its form, its fine striz, and its nearly erect slender

spines, will readily distinguish it from any other species. The

dorsal valve above spoken of was at first supposed to be the young

of Strophodonta perplana Conrad’s sp., but the similarity in size

and character of striz to this species renders it doubtful.

Formation and Locality.—In thin-bedded bituminous limestone,

from above the ‘‘ Bone-bed’” at Smith and Price’s quarries, near

Columbus, Ohio.

tration; still, however, sufficiently distinct to leave no reasonable

doubt of their identity. They are smaller in size than those from

the Upper Helderberg limestone of Canada, but otherwise not

different so far as can be discovered from the imperfect material on

hand.

Genus LEIORHYNCHUS Hall.

Leiorhynchus limitaris Hall, Pal. N. Y., vol. 4, p. 356, pl. 56, figs. 6-21.

Shell small in size, seldom exceeding five-eighths of an inch in width and

usually not more than three-eighths ; form orbicular in outline and lenticular

in profile when not compressed. Valves subequal in depth and rotundity, the

ventral beak slightly extending beyond that of the dorsal and the middle

third or more of the width of the valve depressed, forming a broad but shallow

sinus which extends to within a short distance of the beak. Dorsal valve

elevated in the middle to form the fold which corresponds to the sinus of the

ventral, but which does not continue much beyond the middle of the valve.

Surface of the shell marked by from ten to twelve or more low, angular plica-

tions, four or five of which are seen in the sinus of the ventral, and a corre-

sponding number elevated on the fold of the dorsal valve, and from three to

four or even five mark each side of the shell beyond the limit of the fold and

sinus. The specimens are usually marked also by several strong concentric

lines of growth which form strong varices on the larger specimens, and the

plications are not unfrequently divided by slighter depressions along their

surfaces, which gives them the appearance of being bifurcated, and the plica-

tions themselves are very unequal in strength and seldom extend entirely to

the apex of the valves.

This shell is a very well-marked species and cannot well be mis-

taken for any other of the several species, which, so far as is yet

known, are limited to certain horizons; this one characterizing the

horizon of the Marcellus shale in New York, wherever the species

has been found. Its occurrence in Ohio has not heretofore been

known or suspected, and its presence in numbers, flattened and

compressed in a dark brown, somewhat fossil shale, presenting so

exactly the characters and appearance that it does in the shales of

New York, and also associated with other characteristic forms of

the Marcellus shale, is a somewhat significant fact, and one of con-

siderable importance in its stratigraphical relations.

Prate XI, fig. 16.

Avicula equilatera Hall, Rept. 4th Dist. Geol. Surv. N. Y., 1843, p. 180, Table

latigen ded

Shell small and slightly oblique, somewhat trapezoidal in outline, hinge-

line straight and as long as the greatest length of the shell; beaks nearly

central on the hinge; anterior cardinal angle mucronate, and the anterior

border gradually sloping backward from the point; basal border broadly

rounded ; posterior margin slightly extended at the lower third beyond the

extremity of the hinge, and also slightly sinuate above to form the sulcus of

the posterior wing, which is small and rounded. Surface of the valves very

depressed convex, and marked by numerous fine bifurcating radii, and also by

several concentric undulations which give to the shell a strongly corrugated

appearance.

The species is, in New York, a very characteristic form of the

Marcellus shales, and is readily distinguished from any of those of

the Hamilton or other formations by its fine strie and corrugated

surface. The striz, although somewhat increasing in strength

toward the margin, are frequently bifurcated so that the increase

in strength is not equal to that of simple radii.

Formation and Locality.—In the bituminous shale from above

the “ Bone-bed” at Smith and Price’s quarries, near Columbus,

Ohio, associated with Discina minuta and Leiorhynchus limitaris.

Pterinea similis.

PuateE XI, fig. 15.

Pterinea similis Whitf., Ann. N. Y. Acad. Sci., 1882, p. 214.

Shell small, oblique; the body, exclusive of the wings, being almost regu-

larly although obliquely ovate in outline, the anterior part being the larger ;

hinge-line about two-thirds as long as the entire length of the valve; anterior

wing small, distinctly rounded on the end, and separated from the body of

the shell, on the left valve, by a distinct sulcus along the surface, and which

part I, pl. 1, fig. 18.

552 Contributions to Invertebrate Palzontology.

constricts the margin of the shell; posterior wing one-third longer than the

anterior side, pointed at the extremity and sinuate below. Body of the valve

ventricose, strongly so on the umbone, with a strong, tumid beak, which pro-

jects distinctly beyond the hinge. Surface of the left valve marked by dis-

tinct radii, which plainly alternate in strength over the body of the valve,

but less distinctly so toward, and on the wings; also, by less strong concentric

lines, and varices of growth. Right valve unknown.

The shell is of the type of Pterinea decussata Hall, which occurs

abundantly in the Hamilton group in New York, but is of extremely

small size, and very ventricose; the proportionally strong varices

of growth showing its adult character. The type is one repre-

sented in the Devonian rocks, from the Hamilton to the top of the

Chemung, inclusive, in New York, by several distinct species, but

which is seldom recognized below this horizon. We may, there-

fore, consider it as an additional evidence of the age of the beds in

which it is found.

Formation and Locality.—In the thin shaly layers of bitumi-

nous limestone, from above the ‘“ Bone-bed” at Smith and Price’s

Gilbertsocrinus (Trematocrinus) spinigerus Hall, Descript. of New Species of

Crinoidea from the Carboniferous rocks of the Mississippi valley, plate

1S fren 9.

Body small, of nearly equal height and width, broadly truncated at the

base, slightly rounded and expanded in the lower half of the height, but

generally contracted above to the base of the arms. The base of the cup is

deeply impressed, including the basal and sub-radial plates; the first radials

form the lowest part of the cup, the second radials are placed at the point

of its greatest diameter, and the third at about one-half of the entire height.

The first and second radials are comparatively large, the first being hepta-

gonal, the second hexagonal and the third which are smaller than the second

are heptagonal, obtusely cuneiform above, and support ou each sloping face

two proportionally large supra-radial plates, one above the other, the upper

face of the second one of which is excavated and its surface cicatrized for the

attachment of the true arms, while the summit arms arise from above and are

formed by the junction of the plates from the two adjacent rays. The first

interradial plates are moderately large, are truncated below and rest on the

upper truncated ends of the subradials, thereby separating the first radials

of the adjacent rays from each other. Above the first interradials the plates

are in arches of three plates each for two or three transverse ranges with two

and then one at the top, except in a single lateral area where there is but two

plates transversely.

The anal area is somewhat larger than the other areas, but the arrangement

of plates cannot be determined from excess of silicification. The inter-supra-

radial areas are marked by two plates in each, situated one above the other,

the second one having its upper end forming a part of the summit or dome of

the crinoid. The summit arms have been small but proportionally strong at

the base, the earlier series of plates only being preserved.

The surface of the plates has been elevated in the middle and perhaps ridged

in a stellate manner, but they are too small and too much weathered to allow

of a perfect determination of this feature. The centre of the radial series is

elevated so as to form a distinctly marked ridge traversing the series from and

above the third radial; while the first and second radials bear short obtusely

rounded spines, of a length somewhat greater than the diameter of the plate.

The spines of the first radials project outward and downward at an angle of

nearly forty-five degrees to the line of the base, while those of the second

radials are a little inclined below a horizontal.

I had at first described this as a distinet species from the New

York form, on account of the less depressed interradial areas, but

on more critical comparison have decided that this may be only an

individual difference. It agrees so nearly in all the details of strue-

ture in the permanent features of the crinoid, that it does not seem

possible to point out any distinguishing features that can be called

specific. It is true that in the details of the true and summit arms

there may have been distinguishing characteristics, but in their

absence I should prefer not to name it as a different species from

that one.

The specimens of this species recognized in Ohio are in a very

imperfect condition, being single valves preserved in a limestone

matrix, and consequently much exfoliated when detached from. the

rock. Enough, however, remains to show the strongly lamellose

structure of the surface, which together with the form of the shell

and the mesial rib in the bottom of the sinus of the ventral valve is

sufficient to fully characterize them as belonging to this species.

Contributions to Invertebrate Palzontoloqy. 555

The form of the ventral valve is somewhat triangular, much

wider than high, the beak somewhat prominent and extended

beyond the line of the hinge; body of the valve ventricose and

strongly arcuate, with a deep, moderately wide mesial sinus, the

bottom of which is occupied by a slightly elevated rib, correspond-

ing to the depression in the fold of the dorsal side; from eight to

_ten angular ribs occupy each side of the valve; cardinal area moder-

ately high and incurved, foramen nearly as wide as high. Surface

of the shell marked by strong, concentric, Jamellose lines.

Formation and Locality.—In the blue limestone layers above

the “ fish-beds” at Delaware, Ohio.

Shell obliquely subrhombic including the wings, or the body of the valves

alone obliquely ovate, largest below. Hinge line straight, generally pretty

long, especially on the posterior side, the wing on this side usually extending

backward as far as the posterior extremity of the body of the shell, and some-

times even beyond that point; but always distinctly separated from it by a

broad, more or less deep, rounded sinus; leaving the wing of a triangular

form, with the extremity sometimes rounded but often pointed or even mucro-

nate. Anterior wing on the left valve very much smaller, but still well deve-

loped, rounded on the margin, sloping on the cardinal border, and separated

from the body of the shell by a broad, often deep rounded channel, which

gradually widens with the growth of the shell. Body of the left valve highly

convex, and often with an abrupt cardinal slope much straightened beyond

the middle of the length. Beak large, tumid, projecting somewhat beyond the

cardinal border, and placed at about one-third or less than one-third of the

entire length of the cardinal line from the anterior extremity ; anterior border

of the valve rounding backward from a little below the sinus of the anterior

wing, and usually forming a nearly regular curve to beyond the middle of the

valve before beginning the upward curvature of the posterior portion. Poste-

rior extremity of the valve subangular at the point of greatest length. Surface

of the left valve marked by several strong, distinct, radiating coste, varying

in number on different individuals but usually ten or twelve; those making

the centre of the valve and on the umbonal slope being nearly straight in their

direction from the beak to the base of the shell; while those nearer the ante-

rior end become more and more curved in their direction as they approach the

margin. From three to five intermediate smaller coste occupy the usually

slightly concave but often flattened interspaces. The entire surface of the

valve is often marked by more or less strongly marked concentric lines of

growth, which in crossing the stronger radii often form lamellose projections

on their surfaces when perfectly preserved, but are usually represented by

small knotty prominences as commonly seen. The posterior wing is often

marked by indistinct radiating lines, though not uncommonly these are entirely

obsolete, and the concentric lines are strongly marked. The right valve of

this shell is very slightly concave, proportionally smaller than the left with

the radiating lines much subdued, and the concentric lines not so elevated or

knotty.

The specimens of this species observed from the rocks above the

‘‘ Bone-bed,” in Ohio, have been left valves mostly. I havea recol-

lection, however, of having seen one slab in the Ohio State Collec-

tion, at Columbus, which contained the impression of one right and

one left valve, possessing the usual features of the species common

in the Hamilton rocks of New York; and which was said to be

from layers above the ‘‘ Bone-bed.” The specimen figured on

Plate XI, fig. 17, is from this horizon, and presents all the features

common to the New York Hamilton forms, including the great

gibbosity of the left valve. In the Upper Helderberg limestones

of New York few representatives of this species have been recog-

nized, and those present a coarser ruder form than the Hamilton

group specimens ; and specimens from the limestones from below the

“ Bone-bed,” near Columbus are not uncommon, but are very

large, very coarse, and rude in character, having but a distant re-

semblance to the typical forms of the species. These I strongly

suspect are properly a distinct species, but the examples thus far

obtained have been of so imperfect a character as not to furnish

characters sufficiently marked to determine this question.

Formation and Locality.—In rocks above the ‘‘ Bone-bed ;”’ hori-

zon known as the ‘‘ Petroleum Rock,” in Tully Township, Marion

Co., Ohio. The specimen figured is from the State collection at

Columbus, and-was collected by the Rev. Mr. Herzer.

Genus ACTINODESMA Sandb.

Actinodesma subrecta.

Puate XI, fig. 20.

Actinodesma subrecta Whitf., Ann. N. Y. Acad. Sci., 1882, p. 215.

Shell of moderate size; the body of the shell, exclusive of the wings and

hinge extensions, ovate in outline, and slightly oblique to the cardinal line.

Hinge-line extended in the form of strong auriculations or wings on the sides

of the shell, the upper margin straight, or a little declining on each side of

the beak; anterior wing short, triangular and divided from the body of the

shell by a deep and wide sub-triangular notch ; posterior side long and sub-

jaucronate at the extremity, three to three and a half times as long as the

anterior side, and its area much greater, extending along the body of the

valve to nearly half its length from the beak. Body of the left valve more than

moderately convex, and strongly arcuate or bent between the beak and base

of the shell ; so that when placed on a flat surface, the margin, especially on

the posterior side, would be much elevated above the plane. Beak of the

valve large, sub-tumid, and slightly extended above the cardinalline. Length

of the body of the shell, from the cardinal line to the base, about one-fifth

greater than across it in the opposite direction. Anterior border broadly

rounded,the basal margin more sharply so, with a slight angularity at its

junction with the nearly direct posterior border. Surface of the shell marked

by irregular, concentric, strongly lamellose lines, resembling those of the oyster.

Right valve not yet observed from Ohio.

The species is allied to A. recta—Avicula recta Conrad, but is

shorter, more ventricose on the left side, more arcuate or bent, and

with less extended wings. It is not an uncommon species in the

soft shales of the Hamilton group of New York, where it is readily

recognized from A. recta by the above-mentioned characters. The

A. recta is most common in the arenaceous beds of eastern New

York, while this is the prevailing form among the soft shales fur-

ther west. The right valve is there recognized as being shorter

than the left, concave instead of convex, with an appressed beak or

umbo not extending beyond the cardinal line, and the valve is much

thinner in its substance.

Formation and Locality.—In layers of brownish limestone above

the ‘‘ Bone-bed,” at Fishinger’s mill, Franklin Co., Ohio. Collected

by the Hyatt brothers, of the State University at Columbus.

Shell of medium size, transversely sub-ovate or sub-trapezoidal, much longer

than high. Valves moderately ventricose, most prominent along the umbonal

ridge, which is rather strongly arcuate and sub-angular. Beaks rather small

and appressed, slightly incurved, and situated near the anterior end. Surface

of the valve generally declining from the umbonal ridge to the basal line, and

with a slight sinus or sulcus below the ridge, which gradually widens toward

the margin of the shell, where it causes a broad, but not marked, emargina-

tion in the border of the shell. Cardinal slope narrow and abrupt; hinge-

line arcuate ; posterior end of the shell narrowed ; anterior end broad, rounded,

and slightly excavated below the beaks.

Surface of the shell marked by concentric lines of growth parallel to the

margin of the valve, and often forming rather strong, irregular varices, most

distinctly marked on the anterior half of the shell.

The Ohio specimens, although preserved in an entirely different

matrix, are yet such exact counterparts of the New York shells

that no question can exist of their positive identity.

Specimens of this species, presenting all the specific features of

the typical forms from the Hamilton beds of New York, and found

at Fishinger’s Mills, Sciota, Ohio, in beds of limestone above the

‘« Bone-bed.”’

The general form is transversely elliptical, a little more than

half as long again as high, the valves usually compressed some-

what in the direction of bedding, but still moderately convex and

extremely Unio-like in their general expression. The body of the

valves is marked by the characteristic oblique rib and furrow pass-

ing from the beak to the postero-basal margin, somewhat modify-

ing its border; also by numerous concentric folds or wrinkles

parallel to the margin of the shell, and marking stages of growth.

These wrinkles are usually well marked on the anterior end of the

shells, and become faintly marked or obsolete posterior to the ob-

lique furrow, and on the rather wide posterior cardinal slope. The

hinge-line is nearly straight and shorter than the length of the shell

behind the beaks, causing an oblique truncation of the posterior

end above the longest point of the valve. Beaks large, tumid,

situated well forward on the valves and enrolled. The oblique

ridge is generally more or less nodose from the crossing of the con-

centric folds of the shell.

This species has always been considered a very characteristic and

well-marked Hamilton type; and its occurrence in layers above the

horizon of the ‘‘ Bone-bed,”’ and not below, is very significant.

FOSSILS OF THE ERIE SHALES.

There appears to be no question regarding the equivalence of the

Erie shales of Ohio with the Portage and Chemung groups of New

York; and the Paleontological features of these latter formations

are so well known, and so marked, that there ought to be no doubt

as to their geological position. Their stratigraphical relations also

to the Catskill group, the American equivalents of the Old Red

Sandstone of England, which is considered as typical Devonian,

would apparently leave no doubt as to their place in the geological

record, or to the zodlogical age to which they should be referred.

From these considerations I have considered the following fossils

from the Erie shales, as of Devonian age, an opinion for which I

alone may be held responsible. The group, taken as a whole, are

of special interest on account of the Crustaceans; while the other

forms associated with them are sufficiently characteristic to show

their stratigraphical relations.

Among the concretionary nodules of the Erie shale from Leroy,

several valves of the above-named species. The specimens are

somewhat smaller than the general run of the New York Chemung

specimens, but otherwise cannot be distinguished from them. The

most entire ones are dorsal valves, and are moderately convex, with

a decided mesial sinus. The form is transversly oval or elliptical,

with a short cardinal area and small depressed beak; the striz are

rather coarse, frequently bifurcated and much recurved on the car-

dinal margins and slopes, many of them running off on the cardi-

nal border. Muscular sears large and sub-flabellate, all the features

being the same as the typical forms of the species, modified only in

size.

Paleoneilo similis Whitf., Ann. N. Y. Acad. Sci., 1882, p. 217.

Shell oblong, with nearly equally rounded extremities, and almost parallel

dorsal and ventral margins. Anterior end short, a little narrower than the

body of the shell, resulting from the constriction below the beaks. Posterior

end rounded, with a slight oblique truncation below the middle of the height,

corresponding to the very shallow umbonal sulcus of the valves. Beaks situ-

ated’within the anterior third of the length of the shell, small and enrolled.

Valves ventricose, most prominent just below the umbones, and slightly sul-

cated along the posterior slope. The surface of the shell, so far as can be de-

termined from the matrix, has been smooth or without visible markings. On

the internal cast, the condition in which the specimens are found, the muscu-

lar imprints are faintly marked—the pedal muscles being the most distinct.

CRUSTACAEA.

PHYLLOPODA.

In the 16th Rept. State Cab. New York there is represented a

peculiar bivalve crustacean from the Hamilton group of that State,

under the name of Ceratiocaris punctata; and in the Illustra-

tions of Devonian Fossils, Plate 23, fig. 7, Section Crustacea, it is

repeated under the name Ceratiocaris (Aristozoe) punctata.

Among the fossils of the Erie shales of Leroy, Lake Co., Ohio,

similar forms have been detected, but specifically distinct from the

New York forms: Others, not yet described, have been observed

from the Hamilton and Chemung groups of New Nork. The Obio

species here given, together with the Macrurian decapod and the

following observations on the genera with but slight modifications,

were published in the Am. Jour. Sci. and Arts for January, 1880,

as preliminary to this report.

The fossils in question differ from the true types of Ceratiocaris

in so many particulars, and to so great an extent, that it is quite

impossible to include them under that genus. ‘The reference to

Aristozoe Barr. is, however, still more erroneous, as the forms to

which that name is applied by its author are true Ostracoids,

having all their parts concealed within the carapace, as in Leper-

ditia and its allies; while the forms under consideration are pro-

vided with a bivalve, or at least a two-sided carapace, which in-

closes the thoracic portions; while the abdomen and caudal parts

are naked, or not inclosed within this covering, and are more pro-

perly classed among the Phyllopods.

That this latter character, the naked abdomen and caudal plate,

pertains to these organisms, is abundantly proven by the Ohio

specimens now under consideration. The fossils are found inclosed

in small concretions; and there would be but little chance for

specimens, or parts of specimens of different species, or less likely

of parts of individuals of distantly related generic forms, to be in-

closed in the same small concretion; so we may safely conclude,

that, where parts or fragments of individuals of corresponding size

are found in the same concretion, they are parts of one individual,

or at most, of the same species. In the concretions in question,

there are two examples where parts of the naked abdomen and

caudal plate with its accompanying spines, are imbedded in the

concretion together with the carapace which I have classed as of

the same species. This I consider as ample proof that the parts

belong to the one individual; and that the animal of which they

are the remains, was provided with a naked body and spinose

caudal appendage as in Ceratiocaris. It is also stated in the Illust.

Dey. Foss., that one specimen resembling C. punctata, has been

found with a body similar to that called C. armata, attached to

the carapace, showing their individual relations.

The several species above mentioned, while differing greatly from

Ceratiocaris, possess features in common which at once character-

ize them as a natural group, sufficiently marked to be readily dis-

tinguished. I therefore propose to recognize them as a distinct

genus under the generic name Ecurnocaris possessing the following

characters :—

Genus ECHINOCARIS Whitt.

Echinocaris Whitfield, Am. Jour. Sci. and Arts, 3d series, vol. 19, p. 34, 1880.

Carapace bivalve, valves subovate in outline; united on the dorsal margin

by a straight hinge; the anterior, basal, and posterior margins rounded, and

generally more or less produced posteriorly. Surface of the valves marked

by a more or less distinctly elevated, curved, longitudinal ridge, centrally or

subcentrally situated ; also by one or more (usually three) vertical ridges, or

ridge-like nodes, extending from the hinge-line on the body of the valve, and

usually situated anterior to the middle of the length. Abdomen naked, com-

posed of several segments (four known) and a caudal plate, which is produced

into an elongated spine with a lateral, movable spine on each side. Posterior

margin of the abdominal segments bearing spines on the now known species.

Type Lchinocaris sublevis Whitf.

Among the genera now known and referred to of the Ceratio-

caride there are several distinct types of structure, indicated by

the features of the carapace alone, independent of the changes which

take place in the abdominal segments and in the caudal spine and

appendages. The following synopsis of some of their characters may

serve to illustrate their peculiarities and to show more distinctly the

relations which EKcninocaris bears to other known genera :—

564 Contributions to Invertebrate Palzontology.

Ist Section: Carapace more or less elongated, with a straight or slightly

arched dorsal line; anterior end sharply rounded or pointed (rostrate) ;

posterior end truncate; sides convex, smooth, or simply striate, sometimes

marked by a simple ocular node near the antero-dorsal margin; no ridges or

other nodes. Ceratiocaris McCoy, 1849; Caryocaris Salter, 1862; Hymenocaris

Salter, 1852; Solenocaris Meek, 1872; (?) Colpocaris Meek, 1872. The last

somewhat questionable in character.

2d Section: Carapace similar in form to that of Sect. 1, with the posterio-

basal angles produced into spines, and the surface with longitudinal ridges.

Dithyrocaris Scouler (= Argas Scouler).

3d Section: Carapace rounded at both extremities, elongate-elliptical or

elongate-ovate in form with a straight dorsal margin; surface concentrically

striate, no nodes or ridges. Lingulocaris Salter, 1866.

Ath Section : Carapace triangular, dorsal margin straight ; surface punctate or

reticulate, and concentrically striated (growth lines ?). Dictyocaris Salter, 1860.

5th Section: Carapace suboval or subovate with a straight hinge-line ;

surface marked with longitudinal ridges or representative nodes and ridges.

Surface of parts smooth, punctate, or pustulose. Lchinocaris new gen.

6th Section: Carapace broadly oval or ovate, no straight cardinal line,

consequently no hinge, anterior end rostrated or beaked, surface destitute of

nodes or ridges. Physocaris Salter, 1860.

7th Section: Carapace composed of three pieces, or apparently of three ;

two of which are semi-circular, with the anterior end of each obliquely trun-

cate, forming when the two are united, an anterior triangular notch into which

the third or rostral plate is inserted. Surface concentrically marked by growth

lines; no nodes or ridges. Peltocaris Salter, 1866; Discinocaris Woodward,

1866 ; Aptichopsis Barrande, 1872; Pterocaris Barrande, 1872 (not Heller, 1862).

It will be readily seen from the above synopsis that Hchinocaris

differs materially in the features of the carapace from all the other

genera enumerated. The features of the abdomen and caudal parts

are not as reliable, but are somewhat distinctive as may be seen by

the following table of comparison. (A mark of interrogation indi-

cates that the parts are unknown or only partially known.)

The number of segments here allotted to any given genus indi-

cates the maximum number of naked segments known; some of

them contain species having a smaller number, and in some a much

greater number exists, some of which are concealed within the

carapace. Thus Ceratiocaris is known to possess in one species

fourteen segments in the abdomen, only six of which are naked.

The genus Dithyrocaris McCoy, is described as having three

longitudinal ridges. This feature is seen only when the two

valves are pressed open as in McCoy’s example, so as to present the

appearance of one large plate; in which case the hinge line forms

the middle ridge.

The third or rostral plate in Pelfocaris, Caryocaris, Discinocaris,

and Aptychopsis would appear to be quite analogous to the small

rostral plate seen in Ceratiocaris, and supposed to exist in Dithyr-

ocaris, and perhaps some others, but which is usually absent. It is

possible many of the forms may have possessed this rostral plate, at

least among those that are deeply notched in front when the valves

are spread open. In this case they would as properly be considered

as having three plates in the carapace as those grouped under

section 7. The forms of this section are usually found with the

carapace spread open on the rock, and are then circular and discoid,

but when in their natural position would have been more or less

roof-shaped.

Colpocaris Meek presents some features that raise a question

as to its true affinities. The longitudinal crenulated line and the

inflection of the supposed ventral border do not seem to be properly

understood; and I am of the opinion they may belong to a different

group of Crustaceans.

it slopes abruptly backward to and along the basal line, and again more

abruptly curving around the posterior end of the valve and forward to the

extremity of the cardinal line; below which it is distinctly excavated. The

portion of the valve which projects beyond the hinge is nearly or quite equal

to one-third the length of the valve. Surface of the valves convex, and

marked by ridges and tubercles. The principal ridge commences at about

the anterior third of the valve, and just above the middle, as an elevated,

rounded, and nearly vertical ridge; but soon bends somewhat abruptly, and

is directed backward in a broad, sweeping curve, at less than one-third of

the height of the valve from the lower margin, and gradually decreasing in

strength terminates a little within the margin opposite the longest part of the

valve. Asecond and slightly stronger ridge rises from just behind the middle

of the length of the hinge, and descends with a gentle forward curvature,

terminates near the upper anterior end of the first one. The anterior or prin-

cipal tubercle is large and distinct, and situated near the antero-dorsal angle

of the valve, occupying the greater part of the space between the front margin

and the two ridges just described. Between this and the second ridge the

surface is elevated, forming a low tubercle. The surface of the anterior

tubercle is occupied by several small but distinct pustules, and the entire

surface of the valve covered by a minutely granulose structure.

Abdomen apparently consisting of four free segments; the first one being

short and much thicker than the others on the anterior end, but rapidly

narrowed posteriorly ; the posterior margin being armed with several small

spine-like tubercles. The other three segments are shorter than wide, gradu-

ally decreasing in strength and increasing in length backwards, the first of

the three being apparently less than half as long as wide, their posterior

margius all spine bearing; a long curved lateral spine on each side, with

three short ones between, and all increasing in length backwards from the

first or anterior segment.

Telson proportionally large, of a general triangular form, but slightly pro-

truding at the origin of the movable spines, and projecting behind into a long,

slender, and apparently cylindrical spine, making the telson with its spine

about as long as the four free segments together. Lateral spines cylindrical,

very gently curved, and standing at an angle of about forty-five degrees to

the central spine. Surface of the telson highly convex and somewhat angular

at the origin of the spine. Surface of the crust of the abdomen smooth.

This species is closely allied in the form of the carapace to 2.

but differs in the form of the nodes and ridges, and in the surface

structure, also in wanting the projection at the posterior end of the

hinge; if this feature is natural on that specimen. It is probable

that the abdomen and telson figured on the same plate under the

carapace of 2. punctata, as suggested by Prof. Hall in the expla-

Carapace ovate, widest anterior to the middle, the greatest height equal to

three-fourths of the length, hinge-line straight, rather more than half as long

as the valve, while nearly one-third the length of the valve projects behind

its extremity. Margin of the valve bordered by a narrow, thickened rim.

Anterior end of the valve slightly excavated below the hinge extremity, and

the margin broadly rounded in front; posterior end more pointed, while the

basal line is broadly and evenly curved. At the posterior end of the hinge

the margin is also slightly constricted as infront. Surface of the valve convex

and marked by the characteristic nodes or ridges. The principal ridge com-

mences in an oval node, which is situated just within the anterior third of the

length of the valve; is placed vertically, just above the middle of the height ;

and the horizontal position, which is sharply elevated and slightly curved, is

situated almost in the middle of the width, and terminates a little less than

one fourth of the length from the posterior extremity. The second ridge com-

mences at the hinge-line near the middle of its length, and descends with a

slightly forward direction to within a very short distance of the top of the

vertical portion of the principal ridge. The anterior ridge, corresponding to

the anterior node or tubercle of /. sublevis, is narrow and nearly vertical; of a

slightly sigmoid form, and originates near the anterior extremity of the hinge-

line; the lower end reaching more than one-third the depth of the valve.

The surface of the ridges and of the valve in the postero-dorsal field, as also

of the space below the principal horizontal ridge, is marked by correspond-

ingly large and distinct pustules. Abdomen and telson unknown.

This species differs from C. sublevis in its slightly broader form,

and in the want of the obliquity of the axis of the valve with the

hinge; in the narrower posterior extremity, the pustulose surface,

and in the form of the surface ridges; most notably in the anterior

one being ridge-like and vertically sigmoid instead of round. The

individual used in description is half an inch in length and three-

eighths of an inch in its greatest height.

p- 38, 1880.

Carapace elongate-subovate, about twice as long as high, rounded in front

and somewhat pointed behind; the basal-line straightened along the middle

portion and parallel to the hinge-line ; cardinal line straight and nearly half

as long as the length of the valve, and a little nearer the anterior than to the

posterior end of the carapace. Margin of the valves bordered by a narrow,

elevated, thickened rim, which is expanded considerably in width around the

anterior end of the valve, and terminates in a rounded, elongated ridge at the

posterior extremity of the hinge; from which point the ridge is directed

obliquely forward and slightly downward from the caudal line. The surface

of each valve is divided into three slightly elevated areas, with depressed sulci

between ; an anterior, a central, and a posterior one. The first is situated in

the middle of the anterior end of the shell; the central one unites with the

anterior one below, and extends along the basal margin behind, in a narrow

curved point below the posterior one, and projects upward near the centre of

the valve in a triangular form, terminating in an elevated point just above the

median line. The posterior and largest area is ovate in form, and occupies

a little less than one-half the length of the shell, is narrowed in front and

pointed behind, taking the form of the extremity of the shell. The centre of

the anterior area is slightly tumid. Along the hinge-line and just below its

margin there are three subangular tubercles or nodes, at nearly equal dis-

tances and of nearly equal strength, except that the posterior one is prolonged

at its base into a low, rounded, and slightly curved elevation, which extends

to near the point of the central raised area before mentioned. These three

nodes, together with the oblique ridge-like one terminating the marginal rim,

border the hinge-line on each valve. General surface of the valve finely

punctate, but most distinctly so on the posterior field.

The elongated form of the carapace readily distinguished this

from any of the other species described, while the number of node-

like ridges is a very marked feature. The abdomen and telson of

this species have not been observed, although several imperfect

carapaces, mostly showing parts of both valves, have been obtained.

Macrouran Decapod, which appears to differ so much from any

described genus as to make it undesirable to refer it to any of them.

One of its peculiarities consists in the possession of a pair of very

strong antennal appendages, which project from beneath the anterior

end of the thoracic carapace, and are of such size and strength as

to raise considerable doubt as to their true nature. The existence

of five thoracic limbs, exclusive of these, projecting from beneath

the carapace on one side would seem to place their pedal nature out

of the question; while their great development as seen on the speci-

men would indicate that they had served some purpose other than

simple antenne, and to raise the question as to the possibility of

their having been chelate at their extremities. As only the basal

portions of these organs are represented, however, this question

cannot be satisfactorily determined. Having had an opportunity

of consulting Dr. A. S. Packard, Jr., in regard to them, he gave as

his opinion, that from their position and the representation of the

other five pairs of thoracic members without them, they could not be

other than antennal in their functions, notwithstanding their great

size and anomalous character. Taking this view of their nature,

the specimen would conform strictly to the type of Macrouran

Decapods.

In its generic relations, as well as in its general expression, the

specimen resembles most nearly the genus Pygocephalus of Prof.

Huxley, first given in the Quart. Jour. Geol. Soc. London, vol. 13,

p. 363, 1857, with figures and descriptions of three specimens, under

the name P. Coopert. Neither the genus or the species were well

characterized at that time. It is however again referred to in vol. 18,

p. 420, of the same journal, with a figure of a specimen supposed to

be of the same species, much better preserved, from the coal shales

at Paisley. There are, however, too many limbs represented as

originating from the thorax for a Decapod, and the antennae,

although represented as of large size are not like those of the Ohio

specimen, while there is a second pair shown. In other parts the

figure is indistinct, and in the description the parts are not defined

sufficiently for close comparison. The differences, however, are so

great that I shall propose for this form the new generic name

PALHZOPALZMON, with the following diagnosis :—

Am. Jour. Arts and Sci., 3d series, vol. 19, p. 40, 1880.

A macrouran decapod crustacean, having a shrimp-like body, with a thoracic

carapace narrowed but not rostrate in front, and keeled on the back and sides.

Abdomen of six segments terminated by an elongated triangular and pointed

telson; segments arched, pleura smooth, not expanded nor lobed, their ex-

tremities rounded. Sixth segment bearing caudal flaps, one on each side,

composed of five visible elements, the outer four apparently anculosed to form

a single large triangular plate on each side of the telson. Thoracic ambula-

tory appendages elongated, smooth, and filiform, except the upper (second)

joint, which is laterally compressed. Abdominal appendages short, the upper

joints flattened or convex anteriorly, as if for the attachment of plates or

fimbrie. Antennz with the basal joints strong and well developed, of large

size, much exceeding in strength any of the thoracic limbs. Eye peduncles

short.

This is so far as I am aware the most ancient decapod crustacean

yet recognized, and on that account alone is of great interest. The

character of the caudal plates, in having the parts combined to form

a solid plate on each side of the telson, is also an interesting feature,

if rightly understood. From the impression of the plate as seen on

the ventral side, it was at first supposed to be of a simple element

only, but on obtaining an impression in the fragment of rock, chip-

ped from the top or dorsal surface, the obscure lines of the first and

second joints were detected, while the outer three are only traceable

from the very slight difference in the surface character of two of

them, and the thickened substance of the third or marginal one. Of

the thoracic limbs only parts have been seen, and of the abdominal

members the three anterior ones on one side; the others being con-

cealed by the rock. The eye-stalks appear to have been very short,

judging from the spherical cavities beneath the anterior extremity

of the carapace, which are small, close together, and shallow.

The earliest form of decapod crustacean previously described, so

far as I can ascertain, is given by Mr. Salter in the Quart. Jour.

Geol. Soc. London, vol. 17, p. 531, 1861, as Paleocrangon sociale ;

said to be from the Lower Carboniferous limestone of Fifeshire,

Scotland. There is another supposed decapod, Gitocrangon, noticed

by Richter (Beitriige Paleont. Thiring.) from the Upper Devonian,

which is mentioned by Salter; but of which he says he is doubtful

if it be a crustacean at all. I have not seen the work in which the

original description occurs, and can only judge of its nature from

Mr. Salter’s remarks,

Body slender, the carapace forming a little more than one-third of the entire

length, higher than wide, narrowed anteriorly and truncate behind; being

longer below than above; median line carinate, with a second carina on each

side a little below the crest; anterior end not rostrate but obliquely truncate,

and sloping rapidly backward above the truncation, forming, when looked

upon in front, a narrow elongated shield-shaped and slightly depressed area,

obtusely pointed above and rapidly widening at the base, the lateral carine

rising from the lower angles; lower posterior angles rounded, basal margins

gently curved throughout and bordered by a narrow thread-like band with a

narrow groove within it. Abdomen moderately robust, highly arched along

the dorsal line, the pleura curving inward below, giving a cylindrical form.

Pleura broadly rounded at their extremities on the anterior face, but slightly

angular on the posterior corners; posterior margin of the segments strongly

arching forward on the back. Telson elongate-triangular, a little less than

twice as long as wide, somewhat angular above and marked by a central ridge

below, and by a backward curving transverse ridge across the widest part.

Caudal flap large, forming a triangular plate on each side, the first and second

joints short, subtriangular ; marginal plate of the flap thickened, narrow, and

elongate, central plate narrowly triangular, a little longer than wide ; third

or inner plate of equal length with the second, and a little wider than the

marginal one; the three combined as one, being apparently anculosed at their

margins to form a solid piece. Antenne very strong, the first joint half as

long as the thorax, slightly swollen in their lower half, and flattened on the

under side; the other portions unknown. Thoracic limbs very slender and

only of moderate length, the second joint laterally compressed, making the

height nearly double the width; other joints apparently cylindrical. Abdomi-

nal limbs known only by their second (?) joints, which appear to be triangular

in form, widening below, flattened and plate like in character or slightly con-

vex on the anterior face. (In one case only a single thread-like appendage

can be seen as if projecting from the outer lower angle.)

Surface of the carapace marked by very fine tortuous and interrupted,

raised lines, strongest anteriorly and running obliquely upward and back-

ward; also by a single, slender, distinct, raised ridge, extending more than

one-fourth the length of the carapace, originating at the lower anterior angle,

and passing upward and backward, with a bifurcation at the anterior third of

its length. Surface of the abdomen essentially smooth. Caudal flaps marked

by impressed lines, increasing in number and fineness from above downwards.

The following species is introduced for comparison with Hchino-

caris.

PiatE XII, figs. 17 and 18.

Carapace of large size, being more than one and a half inches in extreme

length, and nearly one inch in height. Form subovate, widest at the anterior

end and straightened on the dorsal margin. Hinge-line straight, nearly five-

sixths of the entire length of the valve, and reaching nearer to the anterior

than to the posterior extremity. Valves very ventricose, but more especially

so anterior to the middle. Margin strong and rounded, separated from the

body of the valve by a distinct furrow, border narrow in front and along the

base, but rapidly widening at the posterior end, and again narrowed toward

the posterior extremity of the hinge. Anterior (ocular?) tubercle large, more

than one-fourth of an inch in diameter, ovate in form, and narrowest in front,

situated close in the antero-cardinal angle; its surface smooth, but capped by

a smaller sub-central, nipple-like tubercle. Behind the tubercle, and nearly

two-fifths of the length from the anterior end, there is a sharp vertical con-

striction of the surface, which extends from the hinge to about one-half the

width of the valve, where it becomes obsolete. Posterior to this there are two

other slight sulci, the anterior of which appears to be slightly curved. Surface

of the crust, so far as can be ascertained from the specimen, smooth, except

near the lower margin, where it is covered with distant, rounded tubercles of

about a twentieth of an inch in diameter each, arranged in three horizontal

rows, Which decrease rapidly in length from below upward; the upper one

containing not more than one-half as many tubercles as the lower or marginal

line.

Formation and Locality.—The specimen is an internal cast, in a

rather coarse, slightly ferrugineous sandstone. It is said to have

come from the Trenton formation in the Ottawa basin of Canada,

the exact locality unknown. I introduced it here for comparison

with the species of Hehinocaris, under the impression that it had

been described by the late Mr. Billings, of the Canadian survey ;

but the strictest search has failed to reveal any such description,

and I have been obliged to give it a name, notwithstanding the un-

certainty of its origin.

Shell elongate-oval, widest in the middle, and nearly twice as long as wide,

very slightly pointed at the upper end and neatly rounded in front, surface

of the valve regularly and evenly convex, and marked only by very fine con-

In the interior of the shell the median line is marked by an

elevated ridge, representing muscular scars, which reaches fully

two-thirds the length of the valve. The impression contains four

elements, two above and two below, the upper pair enclosing the

upper half of the lower. Near the rostral extremity another widely

diverging pair of scars are seen, which also appear double.

The specimen is undistinguishable from examples of LZ. (D.) ligea

irregularly folded together in such a manner as to be difficult of

interpretation. The several plates vary considerably in form among

themselves, and probably represent those from different parts of the

body.

The general form of the plates is triangular, with the apex, or initial point

of growth, a little inclined to one side; the base, or margin of accretion, is

usually the longest side, but not in all cases. One set of plates has the shorter

sides diverging at nearly right angles. On this form, the basal line is convex

for more than two-thirds its length, and concave on the remaining portion,

giving a sigmoidal outline; of the shorter sides, one is straight to near the

apex, where it becomes rounded, and the other is slightly concave. Another

form has the shorter sides diverging at an angle of about 105 degrees, one

slightly convex and the other concave; while the basal margin is convex in

two sections, with a constriction or interruption between the two sections, or

at about one-third of its length from the straight margin. The plates of this

and the preceding form have the surface regularly annulated transversely,

parallel to the basal margin, the annulations very fine, and regularly increas-

ing in size and strength from the apex to the base, except in aged specimens,

where they are again crowded near the border: five undulations may be counted

in an eighth of an inch where strongest. These forms, also, have the straight

margin often fractured and bent, as if they had been broken along that side ;

indicating that two such plates may have been united along this line; and on

the only individual showing several plates together, this would appear to be

the case. <A third form of plate is narrowly triangular or conical, the basal

border being the shortest, and simply convex; the other sides being slightly

curved throughout, but more distinctly so near the apex, which is obtusely

rounded ; the lateral margins are of unequal length, and the annulations of

the surface finer and more closely arranged than on the other forms.

The individual specimens are much too few in number to give

any very satisfactory idea of the general form of the complete body,

or of the number of ranges of plates of which it may have been

composed. There appears to be no reason, however, to doubt the

correctness of the reference of these plates to the genus Plumulites

Barrande, as their general form and surface structure are exactly

like those given by Dr. Barrande, and also to those given in Vol. IT,

Pal. Ohio, pl. 4, figs. 1 and 2 (P. Jamesz), as occurring in the rocks

of the Hudson River group, at Cincinnati; while some idea may

be obtained of the probable form of the entire body from the out-

line figure of a European species, represented in fig. 3 of the same

plate. These Devonian specimens, however, have been of very

much greater size than the above, as the plates here figured are all

represented of natural size, the larger individual plates being more

than an inch in transverse diameter, while the species above referred

to is minute. The occurrence of forms of this genus in rocks of

Devonian age is also a new feature in its history; as those of

Europe are confined to the Lower Silurian formations and the

lower beds of the Upper Silurian; while these occur above the

middle Devonian.

Corallum small, measuring from an inch to one inch and a half in height,

with a transverse diameter at the summit of from five-eighths to three-fourths

of an inch; somewhat regularly tapering and distinctly curved, without dis-

tinct varices of growth, but showing slight corrugations of the surface in most

individuals. Rays well developed, numbering from thirty to thirty-six in the

primary series, with an equal number of secondaries which are much less

strongly developed ; the primary series extending nearly or quite to the centre

of the rather deep calyx. Transverse plates strongly developed. Fosset

situated on the inner side, strong, deep, and extending to the middle of the

calyx in the specimens seen. LEpitheca thin, frequently showing the lines of

the rays impressed on its surface.

The species does not attain a very large size, but is a very com-

mon form on the surface of the limestone, and is somewhat per-

sistent in character, the greatest variation being in the somewhat

more rapid expansion of some examples. The specimens from Ohio

accord quite closely with that figured by the authors of the species

as cited, and also with specimens from the Chester limestone from

several localities in the western States, especially from Chester, LIls.

Body of rather small size. Calyx deep cyathiform, being nearly hemi-

spherical in one example, and somewhat broad obconical in another, and

composed of smooth plates, which have only the general convexity of the

body, or very slightly tuberose. Basal plates minute to moderate size, higher

than wide. Subradials large; height and width nearly equal; two of them

heptagonal and the others hexagonal, the lower sides barely diverging from a

straight line. First radials wider than high, and about two-thirds as high as

the subradials. Anals visible, three in number ; the first elongate pentagonal,

nearly twice as high as wide, and situated a little obliquely on the right side

of the area; the other two are small and pentagonal. Second radials, or first

arm-plates, smaller than the first radials and narrowing upward, wedge-formed

above, and each supporting two arms. On the postero-lateral rays they are

long and cylindrical, with the arms slender. On the anterior ray it is short

and supports two slender arms; while on the antero-lJateral rays they support

a slender arm similar to those of the other rays on the anterior side, and on

the outer side an arm several times larger and stronger than the others, and

composed of larger and stronger plates.

Plates of the arms short and unequal-sided, and giving origin to jointed

tentacule from the longer side of each plate, which is upon the alternate

sides of the arm, or on the same side from every second plate. Surface of the

plates smooth. Length of the arms and subsequent bifurcations not known.

Column small, round, and composed of unequal-sized plates alternating with

each other.

The slender arms are preserved on two individuals to the length of -about

one inch, and the strong antero-lateral arm on one, to more than an inch;

but no evidence of bifurcation appears.

The inequality of the antero-lateral arms will be the distinctive

feature of the species, as the form of the calyx is similar to many

other species of the group.

base of the ambulacral areas, or considerable below the middle of the height ;

the outline of the lower portion being nearly straight lines, or a little concave

between the base of the ambulacral areas and the lower extremities of the

basal plates; while above the form is generally rounding or convex. In a

basal view the form is pentangular, and viewed from above somewhat penta-

lobate; the ambulacral areas being slightly sulcated. Basal plates small,

extending to rather less than half the height of the body below the base of

the areas, and in their lower half are somewhat more attenuate than above,

the cicatrix for the attachment of the column being very small. Forked plates

elongated, and the sinus very broad and deep; the length of the plates being

equal to more than once and a half their greatest width, and their summits

slightly truncated for the reception of the small-pointed interambulacral plates,

which are in length about equal to one-fourth of the entire length of the areas.

Ambulacral areas proportionally wide, distinctly depressed along their middle

and composed, in the specimen figured, of about twenty-six pairs of transverse

poral-plates, from ten to eleven of which occupy the space of an eighth of an

inch in length, in the lower and middle portions, but become shorter above.

Summit openings rather large, surface smooth.

The examples observed vary considerable in form according to

their relative age, the smaller ones being shorter above than that

figured, with narrower areas and shorter poral plates, while the

diameter is somewhat less. The species is proportionally broader

and shorter than P. pyriformis Say, although somewhat resembling

branches, but rise gradually from a thickened space, and gradually diverge as

slender but constantly thickened rays until the normal strength is attained.

The rays are slender, rather closely arranged; about six of them occupying

the space of a fourth of an inch in the widest parts, and from eleven to twelve

may be counted in the same space in the most crowded parts.

Transverse dissepiments nearly as strong as the longitudinal rays, and often

slightly arched upwards between them in the wider parts, but more frequently

directed obliquely upward in passing from one ray to the next, and very often

directed upward to the right from one side of a ray, and to the left on the

opposite side; but they are generally direct in the more crowded portions.

The middle of the ray on the poriferous surface is elevated or roof-like, with

a central crest or ridge bearing distant nodes; a single row of large pores is

arranged on each side, which are usually less than their own diameter apart,

and more or less alternating with those of the opposite side. From two to

three pores occupy each side of each fenestrule, and the pores are margined

by an elevated lip, which on unworn spaces are very prominent. From one

to three similar pores, although sometimes of smaller size, occupy the surface

of each dissepiment. Non-poriferous surface not observed.

This species is somewhat similar to S. biserialis Swallow (Trans.

St. Louis Acad. Sci., vol. i, p. 179), as identified and figured by Mr.

F. B. Meek (Final Rept. of U. S. Geol. Surv. Neb., pl. 7, fig. 5),

but differs in wanting the longitudinal nodose ridge between the

pores of the dissepiments, and in having only a single row of pores

on those parts occupying the middle of the dissepiment as well as

in the more slender, finer, and more direct, and much more crowded

rays, also in having a larger number of somewhat smaller pores

on the rays. Mr. Meek, loc. cit., identifies the above species with

Synocladia Cestriensis (Septipora Cestriensis Prout, Trans. St.

Louis Acad. Sci., vol. i, p. 448, pl. 18, fig. 2), which differs from the

Ohio specimens in the stronger and thicker, as well as more flexuose

rays; in the rounded fenestrules, and smaller-sized pores, which are

also more abundant, often showing three ranges on parts below

bifurcations. On direct comparison of the Newtonville specimens

with specimens from Chester, IIl., these differences, especially those

pertaining to the mode of growth, are very marked and characteristic.

Hemipronites crassum M. and W.

Orthis Lasellensis McChesney, New Pal. Foss., 1859, p. 32, pl. i, fig. 6.

Shell very variable in size and form, but usually more or less plano-convex

as seen in profile, somewhat semi-oval in outline, but usually a little too long

from beak to base to be strictly so considered. Ventral valve more or less

flattened, a little prominent on the umbo, but usually becoming slightly con-

cave toward the front of the shell; cardinal area of moderate height with a

covered deltidium ; beak more or less distorted. Dorsal valve convex, often

quite rotund, but usually depressed convex, with a slightly prominent umbo.

Surface of the shell marked by radiating strial of considerable strength, which

are sometimes sharply elevated and uniform, but on other specimens may be

distinctly alternating in strength or arranged in fascicles; these are crossed

by fine concentric strial which give a finely crenulated surface when viewed

through a lens. Coarser concentric undulations of growth also mark the shell

at irregular distances.

The individuals referred to this species are so extremely variable

in all their characters that it becomes next to impossible to properly

characterize the species by any kind of verbal description. There

are, however, two distinct types of shell included among them,

which possess characters sufficiently distinct to indicate. One of

these is strongly plano-convex in profile, the dorsal valve being

very highly convex, with a large and strong beak, incurved; the

ventral valve usually being distinctly concave toward the front

margin, and the beak usually more or less distorted and twisted.

This form generally attains a considerable size, occurring of a

diameter of two and a half or three inches. The other form is

much smaller, seldom exceeding one and a half inches in its trans-

verse diameter; the shell is less contex, in fact never very highly

rounded, the cardinal area much narrower and the beak less liable

to distortion. These forms usually characterize different beds, and

are easily recognized from each other, but among them there are

usually intermediate forms associated, which tend to destroy the

line of specific distinction, on which account they are usually con-

sidered as varieties of the one species; although there is not the

least trouble in recognizing the different types in well-marked

specimens, still many individuals occur which cannot be satisfac-

torily referred to either, rendering it impossible to strictly classify

them, except as one species.

In placing this species under the genus Streptorhynchus King, I

do so with the belief that S. crenistria, the shell upon which the

genus was founded, is generally distinct from Orthis adspectans

and its congeners, which formed the types of Pander’s genus

Hemipronites; as, besides the strong internal differences, the entire

absence of a cardinal area on the dorsal valve of the former shell

and those of that group, and the presence of a very well-developed

area on that of the latter, together with the difference in the general

form of the shell, offer good grounds for generic separation.

Productus elegans of Authors.

Productus fusciculatus McChesney, New Pal. Foss. 1859, p. 38.

Shell small, rather below a medium size, highly arcuate, and often much

produced in older specimens ; hinge-line short, frequently not more than half

as long as the width of the shell below. Body of the shell somewhat quad-

rangular in the upper part, being flattened or even slightly sinuate along the

median line, and also flattened on the sides; beak proportionally large and

obtuse, not projecting much beyond the line of the hinge when viewed from

above ; auriculations very small. Visceral cavity proportionally small, the

distance between the valves as seen when the front extension of the valves is

removed being not more and generally less than half the width of the shell.

Dorsal valve slightly concave. Surface of the shell marked by strong fascicu-

lating strial, strongest near the front, often showing some stronger ones with

scattered spine bases ; spines often most numerous on the sides of the shell

near the hinge extremities. The upper portion of the ventral and the surface

of the dorsal valve are marked by strong concentric wrinkles, generally dis-

tinct, but sometimes quite obscure.

582 Contributions to Invertebrate Palzontology.

The Ohio specimens of the species are of very characteristic form,

so closely resembling those from the limestone at Chester, Il., that

there is scarcely a chance of mistaking them. They are also usually

of about the same size with the western specimens, only occasion-

ally an individual occurring of large size; in which case they

present the characters of the form described by Mr. McChesney as

P. fasciculatus. A few individuals have been noticed from the

harder and more compact limestone, which are less quadrangular in

the upper part, and the striz appear a little finer and smoother, and

the front of the shell in its extension somewhat rounder than the

usual form. Some of these peculiarities, especially the smooth finer

appearing striz and apparent absence of spines, are the result of

excessive exfoliation, but the difference of form is probably of other

origin.

Productus pileiformis.

Puate XIII, figs. 13 and 14.

Productus pileiformis McChesney, New Pal. Foss., 1859, p. 40.

Comp. Productus cora D’Orb.

Shell of medium size, pileiform, highly arcuate from beak to front and

rounded from side to side, beak small, somewhat pointed, and the body of the

shell somewhat gradually expanding toward the front. Hinge-line usually

quite short and inconspicuous; auriculations small or obsolete. Surface of

the shell marked by very fine radiating striae which are even and usually

quite smooth or free from spine-bases ; increased by implantation on the ven-

tral valve, the added ones at first very small, presenting a strongly alternating

character, but soon becoming of full size. The strize of the dorsal valve does

not present this feature on any of the specimens examined. Body of the shell

marked in the upper part by numerous strong, irregular and unequal, trans-

verse undulations, a portion of which only are projected entirely across the

shell on the ventral side.

There is some question as to the propriety of separating these

forms from P. cora D’Orb. of the Coal Measures; there are, how-

ever, many points of difference as well as many of resemblance,

although none of them on either side are very constant beyond

limited localities; except perhaps the general form and usually fine

strie. There is perhaps equal reason for uniting with P. cora,

P. tenuicosta Hall, P. coriformis Swallow, and some others; but

these names seem useful and convenient in designating those of

different horizons and geographical areas; as there are differences

between them readily recognized and appreciated by those accus-

tomed to examining them, which cannot be portrayed in a figure or

described verbally, but which often serve to detect, or at least aid in

detecting the true horizon of beds of rock which would otherwise

be left in doubt, and it appears necessary to have some means of

referring to or designating such forms when speaking of beds

characterized by them. The form under consideration resembles

those from the Chester limestone of Illinois, used in the description

given by Mr. McChesney, more closely than they do those from

the St. Louis limestone, given under the name P. tenuicosta by

Prof. Hall, which have a larger and more rounded beak and much

longer hinge-line; the striz, however, in its extreme fineness resem-

bles that of the St. Louis limestone specimens.

Spirifera (Martinia) glaber var. contractus M. and W., Geol. Rept. IIl., vol. 2,

Pp: 298; pl. 23, fig. 5.

Shell of medium size, broad ovate or globular in general form, with highly

ventricose or gibbous valves, and a short hinge-line with rounded cardinal

extremities. Ventral valve the most gibbous, with a large and strong incurved

beak ; cardinal area small, one-third or less than one-third as high as long,

divided in the centre by a rather wide fissure; hinge-line less than half the

width of the shell below, the cardinal slopes strongly and abruptly rounded ;

centre of the valve deeply impressed by a moderately wide, subangular mesial

sinus. Dorsal valve nearly orbicular, moderately convex from side to side ;

beak small, slightly tumid, projecting slightly beyond the cardinal line;

mesial portion somewhat strongly elevated to form the mesial fold, which is

of moderate width, not strongly defined at the margins, and does not extend

above the middle of the shell. Surface of the valves smooth to the naked eye,

but under a magnifier is seen to be marked by fine, obscure, radiating lines

and by transverse lines of growth.

All the specimens seen are exfoliated to a greater or less degree,

so that the real surface has not been seen. The surface striw, seen

by the aid of a lens, is too strong and distinct not to be a sur-

face character, as they are readily felt by the hand, although not

readily visible to the unassisted eye. The shell does not attain a

very large size, no specimens examined exceeding one and three-

eighths inches in length, by a transverse diameter of about one and

one-fourth inches. The shells are somewhat variable in form, being

proportionally more or less elongate than the measurements above

given. They also differ much in the size and strength of the mesial

elevation and sinus, and in the length of the hinge-line. I have

much doubt as to the absolute identity of this shell with the Ilinois

shells described and figured by Messrs. Meek and Worthen, from

the fact that these appear distinctly marked by the radiating striae,

while those from the west are said to be smooth, except for the

concentric lines of growth, though occasionally showing faint evi-

dences of obscure radiating lines. The fact that the authors of that

species refer it to Sp. glaber, which is entirely destitute of radiating

lines, would seem to indicate it as different from the Ohio forms.

Several specimens of a Spirifera, of the form referred to S. Keo-

kuk var. by Prof. Hall, have been obtained from Newtonville, Ohio,

which are so entirely similar to those from the St. Louis and Chester

limestones of Iowa, as to be absolutely undistinguishable; the form

of the shell, the form and number of the plications, and the minute

surface structure being exactly as in those.

The form of the shell will vary from longer than wide to much

wider than long, dependent on the extension of the hinge-line. In

profile the shell is extremely ventricose, with a strongly enrolled

beak; a moderate cardinal area, vertically striated; a well-marked

mesial fold and sinus; from seven to ten simple, rounded, or sub-

angular plications on each side, and from four to six bifureating or

dividing plications on the fold and sinus. The plications and inter-

vening spaces, when the surface is well preserved, are marked by

fine longitudinal lines, showing even on partially exfoliated speci-

mens, and are also crossed by still finer transverse strize which un-

dulate in crossing the plications, and on perfectly preserved surfaces

appear to be minutely setose on their edges.

The species is extremely variable in its general outline, as ex-

hibited among the collections from all of the many localities from

which I have examined specimens, especially in the extension of the

hinge-line, and the proportional width of the shell below, and also

in the prominence of the mesial fold; but the form of the plications

and the character of those marking the fold and sinus are usually the

same in all; while the most constant and persistent character, and

one I have been able to detect on specimens from almost every

locality noticed, consists of the minute structure of the surface. I

have lately examined a large number of examples from the lime-

stones and sandstones of the Coal Measures of New Mexico, which

correspond exactly with those figured by Prof. Marcou under the

name S. Rockymontana, and find them showing all the variations

in form noticed among the Keokuk, St. Louis, Chester, and Coal

Measure limestones of Ohio and the West, and am thoroughly con-

vineced they cannot be separated, even as local varieties, with any

degree of safety or satisfaction.

Athyris subquadrata Hall, Geol. Iowa, vol. i, pt. 2, p. 703, pl. 27, fig. 2, and

p. 708, fig. 118.

Shell small or of medium size, subquadrate in outline and strongly trilo-

bate, very variable in its proportional length and breadth, varying froin longer

than wide to much wider than long. Valves ventricose, the ventral the most

rotund, with the beak more or less prolonged and incurved, the extremity dis-

tinctly and rather strongly truncated and perforated by a round foramen of

considerable size; the middle of the valve is marked by a rather deep, more

or less angular mesial sinus, which extends to the beak, but is faintly marked

in the upper third of its length, becoming strong and distinct toward the front

where the shell is prolonged and bent upward in a lingulate extension. Dorsal

valve most rotund on the umbo, the beak obtuse and incurved ; middle of the

valve strongly elevated in front, forming an abrupt, rounded, mesial fold,

which is not strongly marked posterior to the middle of the length, and scarcely

defined in the upper part. On the sides. the shell is bent downward, forming

on each side of the fold a deep sulcus, outside of which the shell is again

inflated or elevated, giving a strongly trilobed form to the front half of the

valve. Surface of the shell marked only by concentric lines of growth, which

are mostly confined to the anterior portion, and are often very numerous and

crowded, giving the shell a much thickened appearance on the margin.

The species is a well-known type of the Chester limestones of

Illinois and Kentucky, and is often identified with Athyris ( Tere-

Terebratula turgida.

PuateE XIII, figs. 21 and 22.

Terebratula turgida Hall, Trans. Albany Inst. vol. iv, p. 6, extract page 6, 1856.

Shell rather smaller than medium size, ovate in general form, the point of

greatest width usually below the middle of the length, and the length nearly

one-third greater than the transverse diameter; base truncate and slightly

emarginate. Valves moderately to highly ventricose, the ventral generally

the deepest and sinuate below the middle of the length, often deeply so; beak

strong, incurved, obliquely and very distinctly truncate, and perforated by a

proportionally large foramen. Dorsal valve highly convex, with an abruptly

incurved beak, which passes within the deltidial opening of the opposite valve ;

front of the valve sometimes convex and sometimes slightly sulcated, causing

the emargination or truncation of the base. Shell structure finely punctate,

and the surface often ornamented by concentric varices of growth.

The specimens from Ohio are larger than those from «the typical

locality (Spergen Hill, Ind.), usually are, but not so large as they

are sometimes found. They correspond closely in form and general

characters, but are not so generally suleated on the dorsal valve.

They are, however, altogether too similar to afford means for specific

distinction. The most of the specimens which I have examined

from Ohio have been slightly distorted by compression, and in this

condition may not afford as many points of difference as more per-

fect individuals would have done.

greatest width. Hinge-line straight, not quite as long as the shell below ;

anterior end acute; basal margin very slightly arcuate, and the posterior

extremity rather broadly rounded ; the point of greatest length being at about

one-third of the width below the hinge-line. Surface of the shell, except for

a short distance within the basal margin, marked by moderately strong, simple

radiating plications, about eighteen in number, as counted at the posterior end

of the specimen figured, but increasing in number with increased growth; the

additions being near the hinge. There are also numerous strong concentric

lines of growth parallel to the margin, often forming undulations of the surface.

I find no American species described that closely resembles this

one; but P. flericostata McCoy, from the English Carboniferous

rocks (British Pal. Foss., p. 499, pl. 3, E, figs. 11-13), is very simi-

lar, but has slightly stronger radii, is somewhat broader, and differs

in having a longitudinal depression just below the hinge-line, which

this species does not possess.

Schizodus Chesterensis.

PuatEe XIV, fig. 4.

Schizodus Chesterensis M. and W., Geol. Rept. Ills., vol. 2, p. 301, pl. 23, fig. 6.

Shell of medium size, transversely subovate in outline, with moderately

convex valves and large, strong, incurved, and projecting beaks. Anterior

end forming one-third the length of the shell, inflated, and rapidly sloping

from the beaks to the longest point, which is near the middle of the height,

and rounding backward below ; posterior end elongated and narrowed, obtusely

pointed at the extremity; basal margin irregularly convex, most strongly

arcuate opposite the beaks ; posterio-cardinal margin sloping somewhat rapidly

from the beaks backward, and the cardinal slope rather abrupt. Surface of

the shell smooth, except for the fine lines of growth.

The specimen used in the above description was identified by Mr.

F. B. Meek, and labelled by him with the name here applied to it.

The specimen is slightly distorted and otherwise injured, but in its

present condition very closely resembles those described in the

Illinois Report. Still on one valve which preserves nearly all of

the posterio-cardinal slope, the lines of growth would indicate a

shell with a much higher posterior end than those above cited; and

when better material is obtained it may be necessary to give it

another specific name.

Genus ALLORISMA King.

Allorisma Andrewsi.

PiateE XIV, fig. 6.

Allorisma Andrewsi Whitf., Ann. N. Y. Acad. Sci., 1882, p. 222.

Shell of medium size or smaller, transversely elliptical in outline; the length

being about twice the height, and the thickness a little more than two-thirds

the height. Valves ventricose, most rotund a little in advance of the middle

and along the umbonal ridge, and wedge-shaped posteriorly, as seen in a

cardinal view ; beaks of moderate size, slightly projecting above the hinge-

line, incurved, directed anteriorly, and situated at about one-sixth of the

entire length from the anterior end. Cardinal line straight or appearing

slightly concave, extending about three-fourths of the length of the shell from

the beaks backward, and bordered by a proportionally large and wide escut-

cheon. Anterior end short, sloping forward from between the beaks, at about

an angle of forty-five degrees to the hinge-line, to near the middle of the

height of the shell, and then abruptly rounding backward into the somewhat

regularly convex basal margin. Posterior end broadly rounded from the point

of the umbonal ridge to the extremity of the cardinal line. Anterior end of

the shell characterized by a very small lunule. Surface of the shell marked

by several strong concentric undulations or folds, which are simple, and regu-

larly increase in size and strength to near the full size of the shell; but near

the outer margin of the valves, in the specimen figured, they are smaller and

doubled by the interpolation of an intermediate rib. The undulations are

crossed obliquely from the beak to the basal margin, just posterior to the

middle, by a narrow, almost imperceptible sulcus, and along the crest of the

umbonal ridge by a line of low-convex and faintly-marked nodes, one on the

surface of each undulation; the posterior umbonal slope is also marked, im-

mediately below the margin of the escutcheon, by a slightly concave sulcus,

across which the undulations are more faintly marked than below.

The species is closely allied to Allorisma clavata McChesney, and

was at first supposed to be identical; but on comparison, it shows

so many points of difference that it became necessary to consider it

as a distinct species.

elongate, and cylindrically oval, the cardinal and basal margins parallel and

very slightly curved, and the extremities very nearly equally rounded ; beaks

small, inrolled, barely projecting above the cardinal line, and situated at

about one-fourth of the entire length from the anterior end. Body of the shell

very evenly and highly rounded from the cardinal to the basal margins, and

almost as convex posteriorly as in front. Umbonal ridge scarcely perceptible,

and the umbonal slope convex ; escutcheon and lunule not defined ; anterior

slope abruptly rounded. Surface of the shell marked by faint concentric

undulations of unequal strength, but most strongly marked on the posterior

end and on the umbonal slope.

The evenly convex and regularly cylindrical form of the shell,

together with the inconspicuous beaks and the equal-sized anterior

and posterior extremities, are distinguishing features of the species.

The shell shows evidence in its form and curvature, in a profile

view, of having been slightly gaping behind.

Straparollus similis M. and W., Geol. Surv. IIL., vol. 3, p. 285, pl. 19, figs. 4 and 5.

Shell about a medium size, helicoid, with a slightly elevated spire, and a

broad open umbilicus in which are exposed portions of several of the volu-

tions. Volutions from four to four and a half in number, moderately increas-

ing in size, flattened on the upper surface, sharply carinate on the upper

peripheral angle, and rounded on the periphery and on the basal and umbilical

surfaces. Besides the carination on the upper lateral angle of the volution,

the larger one often bears a second ridge, of considerable strength, on the

middle portion of the lower surface ; which, on many of the larger specimens,

is developed into a sharply elevated ridge ; while on other specimens of similar

size it is entirely obsolete. Aperture circular. Surface of the shell marked by

fine, closely crowded, transverse lines of growth, presenting a slightly rough-

ened surface under a lens. ;

A number of the specimens on hand, of both small and large size,

are marked on the centre of the periphery by an irregular fringed

expansion of considerable width, presenting an appearance similar

to what might result from a vertical crushing of the volution and

spreading out of this portion of the shell laterally ; but as many of

them do not possess this character to any extent, it can scarcely be

among them shows this feature existing on all of the volutions, the

The shell is of a form common to the Lower Carboniferous for-

the Chemung of New York; species occurring both with and

without the revolving carine, 4. Hecale Hall (Illust. Dev. Foss.,

Naticopsis ziczac.

PuiatE XIV, figs. 15 and 16.

Naticopsis ziczac Whitf., Ann. N. Y. Acad. Sci., 1882, p, 223.

Shell small, the greatest diameter of the body-volution, in the only indi-

vidual seen, being about nine-sixteenths of an inch; and the entire vertical

height of the shell only half an inch. The shell is very obliquely ovate in

form, and consists of about two and a half ventricose volutions, which increase

somewhat rapidly in size to the last one, which forms nearly the entire bulk

of the shell. The surface of the shell is ornamented by a series of strong and

raised transverse lines, which, on the upper volutions, are simple as far as the

suture below, and are directed strongly backward in their passage; but on

the body-volution they appear more distant and conspicuous, and are directed

strongly backward in their passage for about one-third the vertical diameter

of the volution, where they are bent forward at an acute angle, and after con-

tinuing for a distance nearly equal to their length above, are again bent back-

ward. Across the middle of the volution, they make two or more zig-zagging

hends in vertical lines, forming a revolving band of vertical ridges on the

periphery ; below this band, the lines are directed forward obliquely, running

nearly parallel to the base of the shell.

The peculiarity of this shell consists entirely in the structure of

the surface ornamentation, as the general form of the species is

similar to that of many others, but the peculiar zig-zag feature of

the ornamenting ridges will at once distinguish it from all other

described species. Several ornamented forms of the genus are

known from the Coal Measures, but their markings consist of

nodes, either promiscuously scattered or arranged in patterns.

Genus HOLOPEA Hall.

Holopea Newtonensis.

Prate XIV, fig. 12.

Holopea Newtonensis Whitf., Ann. N. Y. Acad. Sci., 1882, p. 224.

Shell of medium size, ovate in outline and ventricose, with a moderately

elevated spire and extremely ventricose volutions, which increase very rapidly

in bulk from the apex. Volutions three and a half to four in number, with

strongly rounded surfaces and moderate sutures. Apical angle about seventy

degrees. Aperture broad ovate, modified on the inner side by the preceding

volution, pointed at the upper end and broadly rounded at the base. Surface

of the shell smooth and the substance very thin.

The form of the shell is much like that of a Macrochilus, but the

substance is much thinner than those usually are, and the base of

the columella is not prolonged, nor is there a solid axis; but speci-

mens show satisfactory evidence of having been distinctly and

largely umbilicated.

Shell small, the specimens observed not exceeding five-eighths of an inch in

length, and the diameter rather exceeding half the length ; spire conical, the

apical angle being about fifty degrees. Volutions about three or tliree and a

half, rapidly increasing in diameter and very ventricose, the last one forming

more than half the length and much the greater bulk of the shell; suture

deep and well marked. Aperture ovate, short, and oblique. Surface of the

shell smooth: Columella not seen.

This species is rather closely related to several forms which have

been described from the Coal Measures of the Western States, but

differs in the form of the volutions somewhat from any, and in the

more regular tapering spire,—those mostly having the body-volu-

tions proportionally enlarged.

Polyphemopsis melanoides Whitf., Ann. N. Y. Acad. Sci., 1882, p. 225.

Shell rather below a medium size, elongate-fusiform; the length nearly

twice and a half the greatest diameter, when not compressed ; spire elevated,

pointed at the apex, the apical angle being about thirty-five degrees when

uncompressed. The specimen figured gives on measurement thirty degrees in

the line of compression, and forty degrees in the opposite direction. Volutions

about five and a half, gradually increasing in size, moderately and evenly

convex, with distinct sutures. Aperture elongate ovate, widest across the

middle, rounded and effuse below and pointed above. Columella not observed.

Surface apparently smooth.

The species is nearly of the form of JZ. fusiforme Hall (Geol.

Rept. Iowa, vol. i, part 2), from the Coal Measures of Iowa, but

is considerably more slender. It is possible it may not properly

belong to the genus, as the columella has not been closely observed ;

but so far as can be determined, it appears to be twisted.

moderately expanded lip around the sides of the aperture. Umbilicus closed,

the axis being solid and the auriculations thickened at their junction with the

body of the shell, covering the central or axial portion. Volutions round and

globular within the auriculations, the inner ones projecting into and strongly

modifying the form of the aperture, which is transversely reniform and ex-

panded at the sides, but not in front. Surface of the shell not known from

Ohio specimens.

The Ohio specimens referred to this species are all quite imper-

fect; being imbedded in compact limestone and the shell replaced

with crystals of carbonate of lime, they do not give the entire

characters, so their correct reference to B. levis Hall is somewhat

doubtful. The species as seen on entire individuals from the origi-

nal locality is slightly keeled on the outer volution, and marked,

rather faintly, by curved transverse strive parallel to the margin of

the aperture, and indicates a rather shallow but broad notch in the

margin of the aperture.

Formation and Locality.—The originals of the species are from

Spergen Hill and Bloomington, Indiana; and the Ohio specimens

are known from Newtonville and Maxville, Ohio, in the Maxville

limestone.

Bellerophon ailternodosus.

Pirate XIV, figs. 17-19.

Bellerophon alternodosus Whitf., Ann. N. Y. Acad. Sci., 1882, p. 225.

Shell of about a medium size, and somewhat subglobose in general form,

with an appearance of being slightly flattened on the dorsum in immature

specimens ; while on the adult forms, the dorsum is marked on the outer half

of the body-volution by a double series of rounded nodes, those on one side

of the centre alternating with those of the other side, and the inner margins

of the two series interlocking with each other. Aperture broadly elliptical,

strongly modified by the projection of the preceding volution, on the inner

margin. Auriculations largely developed and slightly reflected. Axis very

distinctly perforate. Inner lip somewhat callous on the protruding inner

volution. Surface of the shell, so far as can be ascertained, marked only by

lines of growth, beyond the nodes mentioned.

The species is somewhat similar in general form to B. Mont-

fortianus N. and P., from the Coal Measures, in its general form,

but does not possess the strong transverse folds nor the carina

between the lines of nodes marking the dorsum. It also differs in

the alternating positions of the nodes.

N. (Endolobus) spectabilis Geol. Rept. Ill., vol. ii, p. 308, pl. 25, fig. 1.

Shell of medium to large size, composed of several volutions, which increase

rapidly in size, and are transversely elliptical in a transverse section; the

diameter from side to side being about one-third greater than the dorso-ven-

tral diameter at the same point; the lateral edges being obtusely angular, and

the dorsal portion of the section larger and more convex than the inner part,

strongly convex and subangular on the back. Inner surface of the volution

strongly impressed by the one preceding, which it embraces to near the point

of greatest diameter. Umbilicus very broad and deep, exposing each of the

inner volutions to just beyond the point of greatest transverse diameter, the

umbilical surface of the volutions being moderately convex but quite abrupt.

The sides of the volutions are marked by a series of nodes of considerable

strength and size, arranged at regularly increasing distances, and occurring,

as nearly as can be determined from the example on hand, at about every

second septum. The nodes are situated on the crest of the side, and are

obtusely rounded and prominent. Septa moderately distant and but slightly

bent downward on the dorsum. On a specimen measuring about three inches

in its greatest diameter, the whole of which is septate, they are.arranged at

about one-third of an inch apart, near the outer extremity of the last volu-

tion. Siphuncle not observed, and the depth of the septa not ascertained.

The surface of a portion of the specimen bears marks of a series of strong

varices of growth, which have crossed the dorsum and show a strong retral

sinus or notch in the margin of the lip at this point. The varices are seen

on the inner portion of the last volution and appear to have been arranged at

distances nearly corresponding to the septa at the same place. No other

markings of the surface are retained.

The specimen from the Maxville limestone is somewhat smaller

than that from the Chester limestone figured by Meek and Worthen

(Geol. Ill, vol. ii, plate 25, fig. 1), and varies slightly in having

the larger bulk of the volution outside of the line of nodes that

occur on the lateral angles; or in other words the dorsal portion

is larger than the ventral, though on the inner volutions of the

specimen this character is not so distinct. Beyond this slight differ-

ence they appear to agree as far as the characters are preserved. The

difference between this species and Nautilus Forbesanus McChes.

from the Coal Measures, Mercer Co., Ill., are almost too slight for

specific distinctions, where all the examples are internal casts. In

the last-named species the bulk of the volution is on the inner side

of the line of nodes instead of on the outside as in the one now

under consideration, while in the one figured by M. and W. it is

very nearly or quite equally divided. Where all other features are

the same in all, these would scarcely seem to be of specific import-

ance.

From the strong sinus in the lip on the back of the shell the

species has been referred to McCoy’s genus Temnocheilus, and

would be so classed if that division should be retained.

Nautilus pauper.

PratEe XIV, fig. 23. is

Nautilus pauper Whitf., Ann. N. Y. Acad. Sci., 1882, p. 226.

Shell somewhat below the medium size, and consisting of about two and a

half volutions, which increase rather rapidly in size, and are so coiled as to

expose almost the entire diameter of the inner coils in the umbilical cavity ;

the outer one embracing only the dorsal surface of the inner volution. Volu-

tions quadrangular in form, with the lateral diameter only about two-thirds

as great as the dorso-ventral diameter ; while the dorsal and ventral surfaces

are nearly vertical to the plane of the sides, so far as can be determined from

the specimen on hand; or possibly the dorsal surface may be slightly rounded.

The sides of the shell are marked by a faint, narrow, revolving sulcus border-

ing the margin of the umbilicus, and by a correspondingly faint ridge close to

the dorsal margin; while a much stronger rounded ridge occurs on the surface

at about one-third of the width of the volution from the dorsal border. Inter-

nal features of the shell not known.

A single individual only of the species has been observed, and is

altogether too imperfect to reveal all the features. It consists of

the non-septate portion of the shell, in the condition of an internal

cast, with the impression of one side of the entire shell; but gives

no indications of the septa themselves. The only features indicat-

ing its cephalopodous nature, upon which one can rely, are its

symmetrical form, and the evidence of a similar ornamentation on

the opposite sides; otherwise it might have been supposed to repre-

sent a form of Huomphalus.

Calyx very shallow, being low and spreading ; the extreme height to the top

of the first radial plates not exceeding one-fourth of the diameter; the sides,

above the middle of the subradial plates, gradually and almost evenly curving.

Centre of the calyx below deeply impressed, the cavity embracing the basal

and inner half of the subradial plates. Basal plates very small, extending

but little beyond the circumference of the proportionally small column, and

forming by their union a somewhat regular pentagon. Subradial plates of

medium size, four of them being equal, and pointed at their upper ends, the

upper edges being convex; the fifth plate is larger than the others, and is

truncated above by the very small first anal plate, which rests between the

adjacent first radials, and has apparently joined three other plates above.

The surface of this plate bears a single round granulose tubercle. First radial

plates nearly twice as wide as high; their lateral faces being short and uniting

with those of the adjacent plate, except on the anal side, where they are

separated by the first anal plate. Articulating face for the second radials

nearly straight, but deeply grooved. Second radial plates short; that of the

anterior ray being cuneiform above, and has supported an arm-plate on each

upper sloping surface. The second radials of the other rays have not been

fully determined; but on the antero-lateral rays, where partially detached

plates remain, they have been quadrangular, as if for the support of other

radial plates in a direct series. Surface of the inner half of the subradial

plates smooth, while the outer half aud the entire surface of the other plates

are covered with proportionally large, distinct, irregular tubercles, which are

flattened on their surfaces and covered with numerous small, distinct granules.

The granules also extend to parts of the intermediate surface. The upper

margin of the first radial is bounded by an elevated transverse ridge, which is

also granulose.

This species bears considerable resemblance in its general surface-

markings to Hupachycrinus tuberculatus M. and W. (Geol. Surv.

Contributions to Invertebrate Palzxontology. 597

Ill., vol. v, pl. 24, figs. a, b), but the tubercles are very distinctly

granulose. It, however, does not possess the structure of Hupachy-

crinus, having only one small anal plate, the upper end of which

projects above the line of the first radials. The only specimen yet

obtained of the species measures about three-fourths of an inch in

diameter, and is about three-sixteenths of an inch high to the top

of the first radial plates.

Zeacrinus Mooresi Whitf., Anu. N. Y. Sci., 1882, p. 227.

Form of entire body unknown. Calyx of moderate size and pentagonal in

outline, very broadly cyathiform or shallow cup-shaped; the region of the

basal plates being impressed, and the radials but moderately curving upward

at their outer edges. Basal plates small, forming by their combination a

nearly regular pentagon. Subradials proportionally large, wider than high,

four hexagonal and one on the anal side heptagonal. Subradials short, but

not very broad, twice to twice and a half as wide as long; the cicatrix for the

second radials very large and nearly straight. The anal plates, three of

which are preserved, are longer than wide. Column small, round, composed

near the calyx of alternately small and large plates, with very coarse radiating

lines of articulation. Surface of calyx smooth, except a line of granules just

within the margin of the subradial plates.

The second radial plates present the strong specific feature of the

species, and are large and spine-bearing, as in Zeacrinus mucro-

spinus McChesney. The spines are long, much thickened, and bul-

bous in the lower part, presenting in this respect a strong contrast

- with those of that species. The cicatrix for the attachment of the

arm-plates is very large, showing that the plates above were of large

size. Arms and dome unknown.

The species has been quite abundant, as the spines are found in

great numbers, and vary considerably in size, according to the width

of the first radial plates upon which they have rested. But all are

thickened and bulbous, and many of them are more than an inch

in length. They are seldom found attached to the calyx, but are

scattered through the shale in the bed where found.

Shell of moderate size or larger, circular or subcircular in outline. Dorsal

valve convex, with an elevated beak which is directed backward and situated

at about one-third of the length of the shell from the posterior margin. Poste-

rior slope slightly concave just below the apex; anterior slope convex. Surface

of the shell, when preserved, marked by fine, even, but elevated and regular

concentric lines, with flattened interspaces ; about ten or eleven of the elevated

lines occupy a space of an eighth of an inch on the middle of a shell, being

finer within and coarser beyond that point. On the partially exfoliated shell,

fine radiating vascular lines are perceptible. Ventral valve flat, discoidal,

circular in outline, or perceptibly elongated in some cases; the apex a little

more than one-third the length of the shell from the posterior margin. Fora-

men small, elongate-elliptical, narrow, not extending more than one-fourth of

the distance fromm the apex toward the margin, and the depression somewhat

further. Surface marked as in the other valve.

This shell would appear to be identical with the one described

and figured by Messrs. Meek and Worthen as D. nitida? under the

supposition that it was the same as that figured by Prof. Phillips,

in the Geol. Yorkshire Coast, vol. ii, pl. 11, figs. 10-18; but it

differs very much in outline from those figures, as well as those

given by other authors, in its circular form; those being ovate,

narrowed behind and widened in front; also, in having the apex

much more distant from the margin. They also cite D. Missouri-

ensis Shumard, as a synonym of the European species. That author

indicates his shell as parabolic in outline; from which statement I

shquld consider it as distinct from the present species.

Shell small, none of the specimens observed exceeding three-eighths of an

inch in diameter; subcircular in outline, or varied in form by the outline of

the object to which they are attached. Free valve depressed convex, marked

by a few concentric lines of growth; attached valve thin, but with a slightiy

thickened margin. Posterior muscular impressions large and submarginal,

the others being nearly central and forming a small elevation just posterior to

the middle of the valve.

The shells of this species are found attached to the spines of Zea-

erinus and other bodies, one of those figured being upon the oper-

culum of Naticopsis. They are very thin, and not easily detected in

the roughened condition caused by the adhering material in which

most of the fossils from these beds are found. Species of this genus

are rather rare in the Coal Measures, but very few having been

described. Crania Permiana Shumard, from the white limestones

of the Guadalupe Mts., Texas, is a large form, and probably not a

Crania, according to the description given. C. modesta White and

St. John, from the Coal Measures of Iowa, is described as ‘“‘ rather

small, finely punctate, smooth, except somewhat strong concentric

lines of growth toward the margins. Upper valve moderately con-

vex, umbo oblique, nearly central. Lower valve moderately con-

cave.” There would appear to be some similarity between the

upper valves of this and the Ohio species; but the remark concern-

ing the lower valve being “‘ moderately concave” throws consider-

able doubt on their identity, as the lower valve of this species is

attached over its entire surface, while that one would appear to be

free or partially free, if it is a Crania.

Loxonema regularis Cox, Geol. Rept. Ky., vol. iii, p. 566, pl. 8, fig. 2, 1857.

Shell of moderate size, fusiform, with an elevated, rapidly ascending spire,

which is composed of about nine volutions, and has an apical angle of from

twenty to twenty-five degrees, in different individuals when not compressed.

Spire, when viewed in front, forming considerable more than half the length

of the shell, but when measured on the opposite side forms a little less than

one-half the entire length. Volutions slightly convex and in some individuals

presenting a slightly shouldered aspect caused by a very slight, almost imper-

ceptible angularity at about the upper third of the exposed part. Greatest

diameter of the body-whorl situated a little below the suture and decreasing

below. Suture close and not strongly marked. Aperture narrow, elongated,

the outer lip sharp and oppressed in the upper part. Columella twisted and

marked in the lower part by a single, but very strong twisted fold ; anterior

end of the lip rimate. Surface of the shell marked only by obscure lines of

growth.

The species is one of the most elongated forms of the genus yet

recognized from the American Coal Measure strata, and will be

readily recognized by the great length of the spine, especially as

seen in a front view; while the unusually strong columellar fold

will also distinguish it. In most of the specimens observed the

body volution appears to contract more abruptly above in its outer

half than before, giving a somewhat unsymmetrical feature to this

part of the shell. All the examples seen are compressed in the

direction of bedding, usually to the extent of one-third of their

original diameter or more, and some of them are entirely flattened.

This gives them in appearance a much greater apical angle than

the living shell really possessed, which may easily mislead one

in making a hasty comparison. The longest individual observed

measures two inches and five-eighths in length, and has a diameter

of the body-whorl of one inch. The shell is considerably flattened

except in the upper part of the spire, which shows the diameter of

the lower part to have been increased fully one-third. The species

was originally described by Prof. T. C. Cox, loc. cit., as a Lom«o-

nema, and his figure would indicate a shell like Polyphemopsis, but

feeling uncertain of its accuracy in consequence of the great simi-

Loxonema plicatum Whitf., Ann. N. Y. Acad. Sci., 1882, p. 231.

Shell small and slender, spire elevated, presenting an apical angle of about

fifteen degrees ; composed of about eleven volutions, in the example used and

illustrated, which are flattened on the surface in the direction of the spire,

and marked by strong vertical plice, which are directed a little forward in

their passage across the volution from above downward. The body or largest

volution, counting from the lip backward, contains fifteen of these plications,

and the volutions above contain nearly the same number ; those of the several

volutions being in line with those on the one below, but set enough back of

it to be in line with the slope of the plication. This gives them a somewhat

spiral arrangement on the shell, the whole having a twist of about one-fourth

of one turn in the length of the shell. On the last volution the plice are not

distinct much below the bulge of the whorl. Aperture elongate and pointed

below. Suture distinct, but not grooved or banded. Columella straight, about

half as long as the aperture, solid, and terebra-like ; shell without umbilicus,

The species belongs to a group of the genus which has but few

representatives in our Coal Measures; and even those that are

nearest allied to it appear to differ in the form of the columella,

which is somewhat peculiar; and if other species should appear

presenting these same characters, it may be necessary to separate

them generically from the true Loxonema.

simply in close contact with the medio-dorsal portion of the next within, and

exposing nearly the entire dorso-ventral diameter of the shell. Volntions

transversely subpentangular, being angularly convex on the back, strongly

subangular on the sides, and concave on the abrupt umbilical slope, which

forms a somewhat sigmoidal curve resembling an ogee moulding, while the

slightly concave ventral surface is quite narrow, and forms a fifth surface.

Lateral angles obtuse or round subangular, and ornamented by a series of

nodes which are strong and very distinct on the inner coil, broad and rounded

on the first part of the last volution, and become obsolete on the outer third.

The substance of the shell has been very thick and strong, and the surface

shows no evidence of growth-markings or strie. Septa and other internal

features unknown.

The shell resembles somewhat N. spectabilis M. and W., but has

a smaller number of coils in a shell of corresponding size, while the

concavity of the umbilical slope and the subangular back are strong

distinguishing features.

Nautilus (Gyroceras?) subquadrangularis Whitf., Ann. N. Y. Acad. Sci., 1882,

p. 232.

Shell of about a medium size, consisting of two volutions, as seen on the

specimen used, which increase somewhat rapidly in size with increased length,

and are closely coiled so as to bring them in close contact, but not to be in any

degree embracing. The inner volution, however, is coiled in so large a circle

that it leaves an opening within it of about one inch in diameter. The shell

is at first circular in section, but before the completion of the first coil the form

has become modified so as to produce a subquadrangular section, narrowest

on the dorsal side, and the second volution becomes distinctly quadrangular,

being nearly as wide on the dorsum as across the lateral face; but the angles

are all distinctly rounded, and the inner or umbilical margins most particu-

larly so. The inner part of the shell has a line of strong node-like undula-

tions on each dorsal angle, which become obsolete at about the first third of

the second volution. Margin of the aperture greatly extended on the sides

beyond the line of the inner edge, and apparently sinuate on the back. Septa

deeply concave and numerous; those at the base of the outer chamber show-

ing about three chambers in the space of one inch, and gradually decreasing

in distance toward the earlier part of the shell. On the quadrangular parts,

they are deeply receding on the sides and back, and correspondingly advanced

on the angles; a consequence of the quadrangular form on a deeply concave

septum. Surface of the shell apparently smooth and the substance thin.

Siphon unknown.

The species is peculiar in its quadrangular form, and in the wide

opening through the centre; in these characters it differs from any

previously described species. It is of a form that is with difficulty

placed in the genus Nautilus—its characters, so far as the external

features are concerned, nearly resembling those of Gyroceras—and

in the absence of a knowledge of the position of the siphuncle, must

remain doubtful.

common in the upper chert beds of the Coal Measures in Hocking

County, Ohio. Individuals have been observed varying in size

from less than one-eighth of an inch to more than half an inch in

diameter, but all in the condition of casts. The larger specimens,

although much smaller than those usually found in the shaly lime-

stones at Greentown and elsewhere in Ohio, nevertheless show dis-

tinctly by their markings and the distinctness of the muscular scars

that they were adult shells, but probably stunted in growth by

unfavorable conditions, as they are perfect in form and markings.

forming varices at regularly increasing distances. Right valve also marked

by similar fine strie, but with the varices very indistinctly marked, or barely

perceptible under a lens.

The species is a very strongly marked one, and very characteristic

of the Coal Measures. Mr. Meek describes indications of faint radii

between the varices on the examples from Illinois, but which do not

appear on specimens from Ohio so far as observed. The right valve

figured occurs close by the other, and is evidently of the same indi-

vidual; the features are very similar, differing only in the absence

of the strong concentric varices.

Formation and Locality.—In a thin layer of chert of the Coal

Measures, near the farm of Mrs. Banks, Falls Township, Hocking

Vaticopsis Ortoni Whitf., Ann. N. Y. Acad. Sci., 1882, p. 230.

Shell small, with a somewhat depressed conical spire, which forms an angle

of about 105 degrees, and the two and a half to three volutions are obliquely

flattened on their upper side, in the direction of the spire; the outer one

being marked just below the suture by a barely perceptible concave channel

of considerable width, which produces a very slight angularity of the upper

part of the volution. Suture-line slightly grooved. Lower side of the volu-

tion rounded; umbilicus closed; callus slight; aperture obliquely ovate at

the outer margin, but rounded within from the excessive thickening of the

shell. Surface of the shell marked by fine, rather equal and somewhat regu-

lar transverse strie of growth, most distinctly marked on the lower half of

the volution. On the outer half of the last volution, there occur lines of nodes,

very faintly indicated, having a direction opposite to the growth-lines, and

becoming fainter and finally imperceptible toward the lower side.

The species resembles NV. nana M. and W. (Geol. Rept. IIL. vol.

iii, p. 365, pl. 32, fig. 4) in size and general form, but differs from

it in the greater flattening of the volution in the direction of the

spire and in the faintly nodose surface.

Formation and Locality—In a thin cherty band of the Coal

Measures in the railroad cutting at Mrs. Banks’s farm, Falls Town-

ship, Hocking County, Ohio.

PULMONIFERA.

The existence of shells of terrestrial air-breathing Mollusca in

the Coal Measures of this country was first made known in the

year 1851, when Sir Charles Lyell and Prof. J. W. Dawson made

known their discovery of Pupa vetusta in the coal-beds of the South

Joggins, Nova Scotia. Since that time there have been several

additional species discovered in the same region, and others in the

Coal Measures of Indiana. In the Am. Jour. Sci. for November,

1880, Prof. Dawson has given a summary of the species known

from the coal formations up to that time, and also described what

he supposes to be a similar form from the Devonian plant-beds of

St. John, New Brunswick. At the time Prof. Dawson’s memoir

appeared I was working on the form herein described, from the

Upper Coal Measures at Marietta, Ohio, which has proved to be so

entirely distinct from any of those previously known that it became

necessary to found a new genus (Anthracopupa) for its reception,

which was published in the above-mentioned journal, February,

1881.

All the species known up to the time of Prof. Dawson’s paper

were supposed to belong to the inoperculate division of the terres-

trial Gasteropods, and had been referred to the Hericrpa and

Purina. In making the studies of the Ohio shell I had obtained,

through the kindness of John Collette, Esq., State Geologist of

Indiana, specimens of the two forms from that State, and in freeing

them from the matrix I discovered that the species Dawsonella

Meeki Brad. possessed not only the reflected and slightly thickened

lip described by its author, but that the inner lip and much of the

umbilical region were covered by a thickened and flattened callus

closely resembling that of Helicina, furnishing strong presumptive

evidence that it had been provided with an operculum, like those of °

that genus. If this view of its nature is correct, it would place it

with the Henictnrp@ in the operculate section of the Pulmonifera.

The Ohio shell has also some peculiar features that are not recog-

nized among any of the Pupa-form species heretofore described from

this formation. It is of small size, and the general form is similar

to that of the group of the Pup usually referred to the genus

Vertigo; minute’ shells with a nearly vertical aperture, armed with

several projecting tooth-like points within its cavity. This shell

not only presents these same features, but the additional one of

having a small, nearly circular notch in the peristome near the

upper end of the outer lip, very closely resembling the minute

pore-like notch occurring near the upper angle of the aperture in

the genus Pupina Vignard; or that seen in Anaulus Pfieffer.

This latter feature is not present so far as I am aware in any genus

of operculated pulmoniferous shells; at least not in the same degree

nor with the same apparent purpose that it occurs in the operculated

genera above mentioned. The last volution is also flattened or

contracted on the back in a very similar manner to that of Pupina,

as well as of many of the Pup. It would therefore almost seem

as if in this little shell, of this early age, there were foreshadowed

features that afterwards pertained to these two groups of a later

fime; although the projecting teeth within the aperture as here-

after described would preclude the possibility of an operculum in

this case.

Genus ANTHRACOPUPA Whitf.

Am. Jour. Sci., vol. xxi, February, 1881, page 126.

Shell minute, pupaform, with few volutions, the last one unsymmetrical ;

axis imperforate; aperture large, nearly vertical ; peristome thickened, united

above by a thin callus on which may occur one or more palatal teeth ; other

tooth-like projections occur on the inner margin of the lip, and a small, nearly

circular notch, resembling that in Pupina, deeply indents the inner edge of

the outer limb near its junction with the body-whorl. Surface of the shell

marked by fine, nearly vertical lines.

Anthracopupa Ohioensis Whitf., Am. Jour. Sci., Feb. 1881, vol. xxi, p. 126.

Shell small and robust, having a length of about three and one-third mm.

with a transverse diameter of about two mm., and consisting of about four

volutions, the last one extremely ventricose, except on the outer half, where

it is obliquely flattened and contracted, and with the aperture, forms about

three-fourths of the entire length of the shell. Aperture large, longer than

wide, and broadly rounded at the base; lip thickened, rounded within and

forming a flattened thickened rim on the outside; particularly on the lower

part. Labial notch situated very near the upper extremity of the lip, regular

in shape, and forming nearly two-thirds of a circle. A single tooth-like ridge

of moderate size extends inward from the lip at about the middle of the colu-

mellar side, and another of greater size projects nearly vertically from the

middle of the callus which coats the body of tke volution within the aperture.

Umbilical chink small. Surface of the shell marked by fine, nearly vertical,

even striz or lines. Apex apparently mamillated.

Formation and Locality.—In the higher beds of the Coal Mea-

sures, near Marietta, Ohio. The specimen figured is in the collec-

tion of the School of Mines, Columbia College.

Pupa vetusta and P. Vermilionensis are both associated in the

material in which they are found with small helicoid shells (Zonites

and Dawsonella), also pulmoniferous in character; but the Ohio

shell up to the present time is not known to have any such asso-

ciate; on the contrary, like the first individuals of P. vetusta dis-

covered, it is accompanied in one of the layers in which it occurs,

by immense numbers of what appears to be a species of Spirorbis,

which is so abundant that small hand specimens from which two of

the Anthracopupas were obtained appear to be nearly half composed

of these shells. The form of the shell is similar to most species of

the genus, and has a diameter of nearly one line. Although it

occurs packed together in such immense numbers in the rock it has

one surface generally more or less flattened as though for attach-

ment to some foreign body, and has I presume during life been

attached to marine plants, from which it has fallen as they were

decomposed, and thus been amassed on the muddy bottom.

Shell minute, planorbiform, composed of from one to two and a half volu-

tions, tube slender, and very gradually increasing in diameter, marked by

very fine, irregular encircling striz, which are often gathered into little knots

or points near the border of the open umbilicus. Lower side of the shell more

or less flattened as if for the attachment to some foreign substance. Diameter

seldom exceeding one line, generally less.

Measures, near Marietta, Ohio.

The material embodied in the foregoing paper, with the accompanying plates,

was originally prepared for, and was expected to form a part of Volume III. of

the Paleontology of Ohio, and to be published as a part of the work of the

geological survey of that State, then under the directorship of Prof. John §.

Newberry; but owing toa change of policy of the State authorities, the volume

was never published. Subsequently, a part of the matter was published in

the Annuals of the Academy of Sciences in March, 1882, under the title of

‘** Descriptions of New Species of Fossils from Ohio,’’ and references made to

the volume and plates as prepared for the survey report. Consequently the

new genera and species will date from that publication, except a few of the

Crustaceans which had been previously published in the Am. Jour. Science

for January, 1880, pp. 33 to 42, in conjunction with one hundred and twenty-

five copies of an artotype plate distributed with author’s copies. In prepar-

ing the matter for republication in the Annals at the present time it became

necessary to alter the numbering of the plates from one to twelve, as at first

made, to five to sixteen; otherwise the matter stands essentially as originally

prepared.—R. P. W.
