 by Dr. MacCulloch in Nova Scotia. 



Body minutely punctured, copper-coloured brilliant with the splendor 

 of gold ; underneath very slightly hairy, Head channelled between the 

 eyes ; antennae and mouth testaceous ; prothorax widest anteriorly, chan-

 scutellum 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 neir D. flavipes, 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.

 Taken with the preceding.

 lights, glittering like silver. Antennae black ; tubercles of the prothorax 

 prominent ; elytra with an impression near the suture ; last dorsal segment

 its body underneath, which in that species has a golden lustre.
