Black or piceous, reddish beneath ; rather short and broad, 

 very smooth and shining above and rather densely clothed with 

 tawny hairs beneath. The clypeus is rugose, very narrow, 

 emarginate at the extremity, with the angles acute. The head is 

 armed with a moderately sharp and slender horn. The prothorax' 

 is trisinuate at the base, the hind angles are sharp but slightly 

 obtuse, the sides gently rounded and very slightly diverging from 

 the base to the middle, where they are very prominent, and from 

 there abruptly narrowed and concave, with the front angles very

acute. The anterior half of the pronotum is depressed and the 

 posterior half elevated into a broad hump, the anterior edge of 

 which is sharp and usually forms four angles, the two inner ones 

 a little in advance of the others. The scutellum is rather short, 

 rugose and hairy. The elytra are rather feebly punctured, most 

 of the punctures falling into longitudinal rows, and there is a 

 deeply impressed stria on each side of the suture. 



S . The cephalic horn is strongly curved, laterally compressed, 

 and in well-developed specimens bears a strong blunt tooth at the 

 middle of the posterior edge. The pronotum is strongly elevated 

 behind and that portion is entirely smooth, except near the sides 

 and base, where it is rugosely punctured. The anterior half is 

 entirely smooth in the middle but slightly rugose in the front
