DESCRIPTION. 



Body minutely punctured, copper-coloured brilliant with the splendor of gold ; underneath very 

 slightly hairy. Head channelled between the eyes; antenna? and mouth testaceous: prothorax 

 widest anteriorly, channelled, punctured but not thickly, lateral anterior tubercles levigated : scu- 

 tellum small : elytra with a single impression, not far from the base, adjoining the suture ; base 

 elevated : margin of the ventral segments of the abdomen of a fine bright, the anus of a deeper, 

 orange : legs testaceous. 



Very near D. Jlavipes, but the sculpture of the prothorax, the impressions of the elytra, and the 

 colour of the underside of the abdomen are different. It differs from D. discolor in having the 

 prothorax much more thinly punctured, the anterior tubercles, which in that species are near obsolete, 

 more prominent, and the scutellum much smaller.
