Very similarly coloured to D. 15-pmictata ; separated 

 by its narrow form, bifoveolate thorax and coarsely

Head triangular, not longer than broad ; clypeus with a longi- 

 tudinal ridge ; antennae filiform, nearly equal to the body in length, 

 the second joint short, submoniliform, the third more than one- 

 half longer, the foiurth equal in length to the preceding two united ; 

 black, the four or five lower joints piceous, the ninth, tenth, and 

 basal half of the eleventh, white. Thorax about one-half broader 

 than long ; sides slightly sinuate behind the middle, thence 

 rounded and converging towards the apex ; upper surface convex, 

 shining, impmictate. Elytra broadly ovate, dilated towards the 

 apex; upper surface strongly convex, closely punctured, faintly 

 rugulose. 



Similar in shape to D. 15-piLnctata and pauperata. All 

 the specimens that I have seen agree very closely with 

 each other, and differing from the preceding species in 

 coloration.
