 to purplish from certain points of view.

Resembles C. cuprijyennis in colouring — also in shape, but 



having the elytra even more strongly convex longitudinally (i.e., 



as viewed from the side). The seriate punctures of the elytra are 



not in reality much stronger than in cupripennis, but the absence 



of distinct puncturation on the interstices makes them appear 



infinitely more distinct than they do in cupripennis, where they 



are much obscured by the conspicuousness of the puncturation of 



the interstices. The eyes are very much less separated than those 



of cupripennis.
