alia its mucli narrower and more slender form will easily 

 distinguish it. 



Compared with C. cupripennis the interval between the eyes is 

 nearly a half narrower, prothorax of totally different form, seriate 

 punctures of elytra a little less closely placed, interstices all but 

 impunctulate, general form quite different, &c., &c.

This remarkably fine large species is closely allied to C. longulus, 



from which it differs (apart from colour) in its considerably more 



closely punctured head, in the much greater transversity and 



different puucturation of its prothorax, and in the distinct 



though gentle convexity of its elytral interstices, which is even 



more pronounced near the apex than in front.
