in front ^yitll two strong tubercles in tlie middle, and deep exca- 

 vations on each side. The female has the same sculpture, but 

 less marked. The elytra are black, and covered with somewhat 

 regular rows of coarse punctures. The under surface is rather 

 thickly clothed with grey hair.

Niger subnitidus, clypeo punctato subrotundato, thorace sub- 

 laevi fovea utrinque impressa, elytris punctato-striatis, 

 pedibus piceis. 



Long. 4 lin., lat. 2| lin. 



The male and female in this species seem scarcely to differ. 

 The whole upper surface is of a rather dull black, presenting 

 under a powerful lens a somewhat shagreen appearance from 

 the multitude of punctures with which it is covered. The head 

 is smooth behind, but the clypeus is coarsely punctured and 

 somewhat wrinkled, and is rounded towards the apex. The 

 thorax is somewhat smooth, and has an impressed puncture or

 are sti-iated with punctures in the strias. The under surface and 

 legs are of a pitchy black with a few reddish hairs. 



38. — Onthophagus granulatus. 



Niger subnitidus confertim punctatus, clypeo rotundato, tho- 

 race medio subcanaliculato fovea utrinque impressa, elytris 

 substriatis. 

 Long. 4 J lin., lat. 2| lin. 



In this species also, the male and female differ but little ; the 

 greater or less prominence of the transverse ridge on the back

 The head is punctured, while the clypeus is transversely wrinkled 

 and rounded at the apex. The thorax is very thickly punctured, 

 the punctures giving it a granulated appearance. The medial 

 line is slightly marked on the posterior half, and not at all in 

 front, while there is an impressed point near the middle of each 

 lateral margin. The elytra are also thickly punctured, but so as
