being robust and strongly tri-dentate outwardly, are very slender, 

 distinctly arcuate outwardly, and bave a very small sub-apical outer 

 spine and an apical, strongly bifid one, while in the inner part the 

 spur, which is very minute, instead of being apical, is situated at a 

 short distance from the median part, and slightly under the point of 

 insertion of the tarsi ; the genge project considerably beyond the 

 eyes and form with the clypeus a broad obtuse triangle slightly 

 ijmarginate at apex.

Head and prothorax reddish brown, elytra piceous brown, shining, 

 glabrous ; antenna? slightly flavescent, club fuscous ; head distinctly 

 and closely punctate, genaj produced into a very long triangular pro- 

 cess wliich is shghtly sinuate near the junction with the clypeus, 

 and imparts to the head a broadly triangular appearance, the clypeus 

 is blunt at tip and very slightly emarginate there ; prothorax sub- 

 parallel, and sub-diagonal laterally towards the basal part, marginate 

 along the base which is sinuate on each side of the median part, 

 little convex, deeply and very closely punctured, except in the middle, 

 from the apex to two-thirds of the length ; elytra oblong, slightly 

 iimpliate at about one-fifth of the length, deeply and closely punctato- 

 striate with the intervals moderately convex in the dorsal parts, but 

 tectiform and carinate behind and on the outer sides wdiere the 

 striai are crenulate, these intervals are finely but deeply punctured, 

 -the sixth and seventh striae reach only the median part of the 

 humeral callus, and the eighth is very Httle shorter ; under side, 

 including abdomen, almost glabrous ; metasternum normal, apical 

 spurs of posterior tibia not quite as long as the basal joint of the
