and is much prodiicod in front of tlie ' scutellum, Sciitellnm sraall, 

 but quite visible. Elytra rather deeply striated, the Striae simple, 

 the internal interstioes distinctly convex , the outer ones quite flat, 

 finely but distinctly punctured, the suture sbining, the other internal 

 interstices also a little shining especially towards the extremity, which 

 is provided with fulvous setae; the base, within the humeral callus, 

 is depressed. Pygidium obscurely puuctured. Metasternum sliining, 

 only sparingly and finely punctured, and almost free from pubescence, 

 it is without Channel, but transversely depressed or constricted in the 

 middle towards the front, in a peculiar manner. Legs and abdomen 

 pitchy , the former rather slender , the tarsi long and slender ; the 

 antenuae red. 



India, a single female. 



This species has exactly the facies of a female Bulas, and must 

 be placed at the extremity of the genus Onitis, next to Buhas. It is 

 allied to 0. castaneus Redt, but is readily distinguished by its black 

 colour, and the more convex interstices of the elytra. As I am only 

 acquainted with the female, and as the two individuals of 0. castaneus 

 in my collection are both males, I cannot give fully its distinctive 

 characters.

Front of the clypeus emarginate in the middle, in the centre of 

 the emargination with a slightly recurved tootli , the front part is
