often slightly emarginate in the middle ; lateral margin broadly 

 dilated in front, hinder portion subparallel, hinder angles acute, 

 slightly produced; upper surface smooth and nitidous, some- 

 what sparingly clothed with pale hairs; transverse sulcation 

 deeply impressed, the surface of the thorax behind its posterior 

 margin thickened and distinctly raised ; in the centre of this 

 raised surface is a more or less distinct longitudinal groove. 

 Elytra broader than the thorax, nearly subcylindrical in the ^ ; 

 rather broader and more depresse(f in the ? .

Head short ; front clothed with adpressed hairs, with a more or

 rugulose ; vertex nitidous ; face grooved as in D. laticolle ; three 

 or four upper joints of antennae yellowish white. Thorax three 

 times as broad as long ; apical margin concave, sometimes 

 slightly notched in the middle ; side margins broadly dilated in 

 front, nearly straight and slightly diverging posteriorly, hinder 

 angles acute ; disk impressed in a similar manner to that of D.
