XII. On several Species of Bolbocevas, Kirhy, from New 

 Holland, in the Collection of the Rev. F. W. Hope, 

 F.R.S., (fee. By the late Mr. William Bainbridge, 

 Assistant Curator to the Entomological Society of London. 



[Read 3 June, 1839.] 



M. le Comte Laporte de Castelnau, in the third volume of the 

 " Histoire Naturelle des Aniinaux Articules," makes mention 

 of about twenty species of Bolboccros, a genus of lamelHcorn 

 beetles allied to Gcotrupcs. It is remarkable that only one of

 F. W. Hope several new, large, and singular species, I solicited 

 his permission to describe them, and now offer them to the En- 

 tomological Society of London.

 English. 



Entirely of a castaneous brown, the head and punctulated part 

 of the thorax and scutellum of a darker colour. Head elongate- 

 quadrate, in the middle is an elevated carina, with the anterior 

 angles circularly recurved, and descending to the margin; from 

 whence arises another keel, ascending higher than the first, with 

 the apex furcate, the intermediate spaces being closely rugulose- 

 punctate. Thorax convex, very broad behind, anteriorly trun- 

 cate, roughly punctate in the middle, and very glossy in front, 

 with two circular perforations near the anterior margin ; in the
