One specimen , collected in Oregon by Dr. J. K. Townsend , 

 and given me by M. Wilcox. Ressembles the next , but is a much 

 thicker species , with a more tumid thorax. Colour deep black , 

 sprinkled with very line whitish hairs : front very finely punctulate ; 

 margin slightly reflexed : thorax at its greatest breadth nearly one- 

 half wider than long, strongly narrowed in front , and very much 

 rounded on the sides, gradually narrowed for the posterior third , 

 with the sides straight near the base : disc convex , very finely , 

 almost imperceptibly punctulate , obsoletely channelled : basal 

 strise moderately short , deep : elytra about twice as long as wide, 

 not wider than the widest part of the thorax , oval , slightly poin- 

 ted behind : strise finely punctured , not deeper posteriorly : in- 

 terstices flat , scarcely perceptibly punctulole : feet black ; claws 

 diaphanous. 



This species is perhaps related to C. latiusculus Esch. but the 

 pubescence of the thorax is not fuscous , nor are the knees ferrugi- 

 neous , as is required by the description of that species.
