closely, not coarsely punctate, pubescence somewhat brownish ; scutellum rather 
densely clothed with paler yellowish hairs ^ elytra a little wider than the thorax, 
widest one-third from base, humeri rounded, sides arcuate, gradually narrowed 
in apical two-thirds, but obtuse at tip; disc convex, striate; strife all punctate, 
intervals flat, moderately closely and finely punctate; body beneath piceous, 
finely fulvo-pubescent, epipleurm usually paler; prosternum sparsely punctate at 
middle, at sides intermixed and finely pubescent, the lobe very coarsely punc- 
tate, moderately prominent; propleurm o])aque, finely and closely punctate 
metiisteruum moderately closely punctate with intermixed punctures; abdomen 
very finely and closely punctulate, the punctures unequal; legs rufo-testaceous, 
the femora usually darker. Length 5.25—6.5 mm. ; .21 — .26 inch. 
'riiis species varies in color from piceous black to brown, the elytra 
being often quite pale. It may also vary in the form of the sides 
of the thorax, the subangulation being scarcely evident in some 
(lacmtris), but the thorax is always narrowed in its apical two-thirds. 
The strife of the elytra may vary in sharpness, and their punctures 
are sometimes scarcely evident on the disc. 
The spot of pale pubescence near the apex is quite characteristic, 
and its distinctness is not due to the abrasion of the rest of the sur- 
face. In well preserved specimens the greater portion of the elytral 
pubescence is finer and more brown, consequently less distinct. 
No special sexual characters have been observed. 
(Occurs from Nova Scotia westward through Massachusetts, New 
York, Canada, Hazleton, Pa. (Dietz), to Oregon and Alaska. 
C. iiiiprcssicollis Maun. — Oblong, moderately convex, piceous or brown- 
ish, the elytra paler, surface slightly feneous, the pubescence sparse, pale brown- 
ish, rather dense and fulvous on the scutellum; antenufe feebly serrate, piceous. 
the basal joints paler ; head coarsely, moderately closely punctate, the frontal 
margin scarcely elevated ; thorax scarcely wider than long, sides nearly straight, 
arcuately narrowed near the front, a faint trace of a sinuation near the ungles, 
these acute, scarcely at all divergent; the carina feeble, basal incisures distinct: 
disc convex, the median channel distinct from base to apex ; surface moderately 
closely punctate and (for this group) rather coarsely, pubescence fulvous ; scu- 
tellum rather closely pubescent; elytra oblong-oval, widest near the middle, the 
humeri rounded; disc convex, moderately deeply striate, strife all punctate, in- 
tervals flat, rather closely punctate and posteriorly slightly asperately ; body 
beneath piceous, finely pubescent and subopaque, epipleurfe paler; prosternum 
sparsely punctate, more coarsely in front and more finely at the sides ; propleurte 
opaque, with dense fine punctures, with coarser intermixed ; metasternum finely 
indistinctly punctate, punctuation double; abdomen densely finely punctate, 
with coarser punctures intermixed at the sides; legs rufo-testaceous. femora 
darker. Length 5 — 6 mm. ; .20 — .24 inch. 
This species superficially resembles abbreviatus, but the form of the 
thorax and the absence of the spot of pubescence near the apex will
