2- — Black, shining. Head broad, without frontal impressions, 

 except a setigerous puncture on each side of the clypeus ; the 

 clypeal suture distinct ; eyes convex, but not prominent, the 

 sides of the head a little swollen behind them ; antennae submon- 

 iliform, depressed (in the specimen before me the flattened sides 

 of the antennae after the 3rd joint are punctated). Labrum rounded 

 on the sides, truncate and sex-punctate in front, the middle lightly 

 canaliculate. Prothorax convex, a little broader than long 

 (7x8 mm.), a little narrowed to the base ; the lateral margins 

 conspicuous, almost straight on the sides between the marginal 

 punctures, thicker and somewhat crenate behind, reaching the base 

 in full width and without any sinuosity, wider in front to the 

 anterior angles — these obtusely produced ; the base truncate, not 

 margined ; the disc transversely striolate ; the median line very 

 lightly marked. Elytra oval (15 x 10 mm.), convex, smooth, very 

 declivous behind, peduncle broad and but little below the plane of 

 the elytra in the middle ; scutellum broadly turbinate, instead of 

 semicircular the usual form in the genus ; sides parallel ; the 

 shoulders rounded ; the lateral margins narrow, finely reflexed, 

 wider towards the apex ; a row of fine punctures (about 13) along 

 the sides from the shoulders to near the apex. Anterior thighs 

 long, flattened, the tibiae slightly uneven exteriorly towards the 

 apex, the apex broad ; middle tibiae punctate, spinous, widened, 

 but not the least dentiform externally at the apex ; trochanters 

 oval, bluntly pointed behind. Presternum not excavate between 

 the coxae, rounded behind. Ventral segments impunctate, except 

 for two fine punctures on each side of the anus.
