sharp at tip, genae carinate but not projecting beyond the lateral line 

 of the clypeus ; male with a sharp, clypeal recurved horn ; female 

 with two frontal recurved horns situated at the base of the suture of 

 the genae, the head is glabrous on the upper side ; prothorax nearly 

 plane above, but sub-vertical at apex, covered with a very short 

 and very dense, somewhat silky, brownish pubescence ; slighth' 

 impressed longitudinally towards the centre of the base, marginate 

 laterally and at apex, but not along the base ; scutellum long, sharp 

 at tip ; elytra very distinctly carinate above the outer margin, which 

 it overhangs, slightly sinuate laterally below the shoulder, and a 

 little ampliate from there to past the middle, quite 2^1ane, somewhat 

 narrowly striate, the striae not geminate, intervals plane, finely 

 aciculate and extremely briefly bristly, the bristles being a little 

 more distinct towards the apical part the extreme edge of which is 

 briefly fasciculate ; pygidium granular, the granules small and not 

 closely set ; metasternum scabrose laterally, closely punctured in the 

 centre, distinctly canaliculate longitudinally in the middle for half the 

 length, and having on each side of the anterior part a short, flexuose 

 carina ; prosternum normal ; legs punctulate, inner spurs very long, 

 basal joint of posterior tarsi broad, and longer than the other joints-

 densely setose ; labial palpi thickly setose, two-jointed, first joint 

 moderately short, produced triangularly inward, second compressed, 

 three times as long as the second, gradually ampliated from base to 

 apex, where it is truncate, the width of this ultimate joint varies a 

 little according to the species, and in some there is even a very rudi- 

 mentary trace of a third, subulate joint ; lobes of the ligula very 

 long, and membraneous ; maxillae long, moderately thick, apical lobe 

 broad and long, inner one narrow, maxillary palpi similar to those of 

 Onitis ; antennae eight- jointed, clava large, ultimate joint flat, basal 

 joint a little incurved and as long as the four following; head with trans-
