 The extension of the metallic colouring to the head (which 

 .seems constant) is an unusual character. The combination of 

 eyes widely separated ^not much less widely than in C. cupri- 

 pennis) and the prothorax with its front margin not less than f 

 as wide as the base places this species among a group of very 

 limited number. In that group the metallic head, non-striate 

 elytra, comparatively large size, will distinguish the present 

 species. The sculpture of the prosternum seems variable — indeed 

 I tind it an unsatisfactory character in most of the Chalcopteri ; 

 in this species the prosternum is widely concave down the middle 

 (at any rate in the front part), but the middle of this sulcus is 

 iiiore or less convex, so that a kind of keel runs along it which in 

 some examples is little noticeable and in others almost fills up the 

 concavity. The sculpture of the elytra is almost exactly as in C. 

 cupripetmis. The elytral outline viewed from the side is an even 

 gentle curve with its summit at (or almost behind) the middle.
