Head slightlv elongated behind the eyes; the hitter deeply emar- ginate in front, not divided as they are in the type si)ecies. Antennae of the male twice as "long as the body, fringed with hairs under tlie third and succeeding joints ; third joint shorter than the fifth ; iifth to seventh subequal; eighth to tenth gradually diminishing in length, and united scarcely longer than the eleventh; antenna) of the female a little longer than the body, with ti.e eleventh joint very little longer than the tenth. Prothorax longer than broad in both sexes, slightly rounded on each side, constricted at the base and apex ; transversely and not very strongly wrinkled above, with a line or band bare of pubescence along the middle. Elytra conjointly rounded and unarmed at tlie apex. This species, though it has a strong resemblance in shape and coloration to D. pauper, Pasc, the type of the genus, is easily distinguished from it by the following well-marked structural characters :—the head less elongated behind the eyes : the eyes not divided ; the third joint of the antennae shorter than the fifth ; the elvtra rounded and unarmed at the apex.
