elytra dull brick-red^ and the antenna red with a pale yellow 

 club. 



The form is broad and convex, with the head semicircular, 

 ruo-osely punctured, and scarcely emarginate in front. The 

 prothorax is coarsely and densely punctured, completely 

 margined, with the base slightly angulated in the middle, 

 the anterior angles rather produced but not sharp, and the 

 posterior angles almost obsolete. The elytra are shallowly 

 striated, the striae containing very elongate ])unctures having 

 each a raised margin, and the interstices are flat, opaque, and 

 almost smooth. The pygidium is flat, opaque, and coarsely 

 and densely punctured, and the metasternum is rather closely 

 but not strongly punctured and not prominent in front. 

 The front tibiae are moderately long and armed with four 

 strong but not sharp teeth. 



(^ . The head bears behind a pair of long, curved, and 

 widely divergent horns, like those of the European 0. taurus, 

 but strongly elbowed internally near the point of origin. 

 The prothorax has a slight longitudinal excavation in front. 



$ . There are two slight transverse carinse upon the head 

 and the prothorax is only feebly channelled along the middle. 



There are specimens in the British Museum and M. Rene 

 Oberthiir's collection. 



Var. suJjcrihratus. 



The punctures of the prothorax are exceedingly dense and 

 continent, so that the metallic lustre is scarcely traceable, 

 and the anterior excavation in the male is limited behind by 

 two rather sharp tubercles, the corresponding elevation in 

 the Sikkim form bein^ quite blunt.
