 black, the margins of the abdomen being reddish-yellow ; antennae red 

 for half their length, and the rest black ; thorax sublunate, very finely 

 punctured on disc, more. strongly at sides, with posterior angles rounded; 

 elytra raised towards base, sloped towards apex, confusedly, subrugosely, 

 and moderately strongly punctured ; legs entirely reddish-testaceous.

 Round, subhemispherical, very convex, upper surface green or yellowish- 

 green, under-side black with the abdomen entirely yellowish (a character 

 that will at once distinguish the species); antenna: testaceous, slightly 

 darker towards apex; thorax sublunate, very finely punctured on disc, 

 more distinctly at sides, posterior angles marked; elytra deeply and 

 confusedly punctured, with a row of strong punctures towards margins, 

 interstices smooth and shining, suture somewhat raised at anterior third ;
