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

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

 tbickcr species, willi a more lumid ihorax. Colour dcep black , 

 spriiikled wilb very finewhitishliairs : front very fincly punclulate ; 

 margin slightly reflexed : thorax at ils greatesl breadlh nearly oiic- 

 half wider «han long, strongly narrowed in front , and very much 

 rounded on the sides, gradually narrowed for ihe posterior ihird , 

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

 almosl imperceptibly punctulate , obsolelely channelied : basai 

 siriœ moderalely short , deep : elytra about twice as long as wide, 

 iiol wider than the widest part of the thorax , oval , slightly poin- 

 led behind : striae finely punctured , not deeper posteriorly : in- 

 terstices flal , scarcely perccplibly punctulate : feet black ; claws 

 diaphanous. 



This species is perhaps relaied lo C. latiiisculus Esch. but ihe 

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

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