third less than the greatest discal width, discal lines fine, one- 
third shorter than the suture. Addomen with the base segment

than D. longulum, red-brown, pubescence short, sparse.

Antenne shorter than head and prothorax, rather stout, second 
joint globular, second to seventh rounded, equal in length, 
scarcely perceptibly increasing in width, eighth longer, trans-
