NORTH AMERICAN COLEOPTERA. 
11 
acute, distinctly carinate; surface moderately closely, but not densely punctate^ 
very evidently lonfiitudinally strigose ; disc feebly convex, a distinct basal in- 
cisure opposite the fifth stria; elytra slightly wider posteriorly than the thorax, 
humeri oblique, sides feebly arcuate, more so in the J ; disc sub-depressed, 
striate, striae punctured, more coarsely at sides, especially near the humeri; in- 
tervals flat, rather closely punctate; prosternal lobe long, its apex with a feebly 
beaded edge and without a transverse impressed line posteriorly ; surface coarsely, 
not closely punctured, feebly pubescent, propleurse opaque, coarsely sparsely 
punctate and distinctly pubescent; metasternum and abdomen sparsely coarsely 
punctate, with extremely fine punctuation closely placed between them, the 
vestiture of pale brown, fine pubescence with intermixed golden scale-like hairs. 
Length 7.5 — 8.5 mm. ; .30 — .34 inch. 
The male is more slender and parallel than the female, but shows 
110 other differences. 
Occurs in California at San Jose and vicinity. 
C. funebris Cand.— Oblong, depressed, black, opaque, finely pubescent; 
legs piceous, sometimes with the tibise paler; head coarsely and moderately 
closely punctate; antennae piceous, feebly serrate, the joints all longer than 
wide; maxillary palpi not prominent, the last joint triangular; thorax a little 
longer than wide, scarcely narrowed in front, widest at middle, sides regularly 
feebly arcuate, sinuate in front of the hind angles, which are acute, slightly 
divergent and with a short carina; disc feebly convex, a distinct incisure each 
side of base; surface very densely punctured and without strigosity; elytra a 
little wider than the prothorax, the sides nearly parallel, narrowed at apical 
third, striate, strife punctured, intervals flat, closely punctate and quite rugous 
at base; prosternal lobe moderately prolonged, its edge distinctly beaded and 
with a deeply impressed marginal line and another transverse line of variable 
distinctness posteriorly, coarsely and closely punctate in front of the transverse 
line, more finely posteriorly; propleur® very opaque, very scabrous ; metaster- 
num and abdomen closely finely punctulate, but not opaque, finely cinereo-pu- 
bescent. Length 7.5 — 8.5 mm. ; .30 — .34 inch. 
This species is more opaque and blacker than either of the other 
species, while the punctuation of the thorax is dense and simple, not 
strigose. The sculpture of the metasternum shows but few coarser 
punctures and these near the middle, while the abdomen is entirely 
free of them. The legs may be entirely piceous, or have the tibise 
somewhat paler. There is absolutely no surface lustre in this species. 
Occurs in California and western Nevada. 
C. planatus Lee.— Oblong, nearly parallel, depressed, black, with faint 
bronze tinge above, beneath opaque; antenufe black, a little longer than the 
head and thorax, feebly serrate, joints all longer than wide; head coarsely and 
moderately closely punctate; thorax distinctly longer than wide, widest slightly 
behind the middle, not narrower in front, sides feebly arcuate, sinuate in front 
of hind angles, which are slender, acute and slightly divergent, distinctly cari- 
nate ; disc feebly convex (basal incisures distinct), coarsely, not densely punctate.
