Somewhat resembles C.nigricornis, Fab., in form ; but the 

 thorax is relatively a little naiTOwer, the sides are a little more 

 rounded, the posterior angles more rounded ; the elytra are 

 slightly more attenuated posteriorly. The antennse are 

 blackish, with the first three joints reddish yellow. The head 

 is sculptured as in C. nigricornis^ but rather more distinctly, 

 the punctures are more distinct towards the eyes and on the 

 neck. The thorax is one fourth broader than long, gently 

 convex, strongly punctured but not very thickly ; the punc- 

 tures, however, are closer near the suture and towards the 

 hinder margin ; there is a single well-defined fovea near the 

 posterior margin, slightly nearer to the side than to the sutural 

 line. Scutellum impunctate. Elytra somewhat broader than 

 the thorax, less parallel at the sides, and more narrowed to- 

 wards the apex than in C. nigricornis ] the pubescence is 

 rather less close, the stripe are well marked (rather more so 

 than in C. nigricornis)^ the interstices are thickly and distinctly 

 punctured, but the punctures are not crowded. The underside 

 is black, shining ; a few strong punctures are scattered over 

 the prosternum and the metasternum. The legs are reddish 

 yellow ; the apices of the tibi^ and the tarsi are pitchy. 



Var. Elytra with a reddish-yellow spot near the apex on 

 the third to sixth interstices. $ .
