armatis : cubitis quadridentatis, intus ciliatis, basin versus dente 

 valido instructis. Pedes intermedii, tenues satis : tibiis brevi- 

 bus ; postici tibiis longis admodum subarcuatis, extus barbatis. 

 Inter antepectus et postpectus vallis satis profunda interponitur. 

 This curious species, which is a native of the Soudan, forms a 

 distinct and new type in the genus Scarabceus^ distinguished from 

 those already known, not only by its immense shoulders, or ante- 

 rior pair of thighs, but also by the vast chasm interposed in their 

 underside, between the manitrunk and the alitrunk, and by the 

 want of the anterior sinus of the prothorax, which in them receives 

 the head, and which in the insect above described, is replaced by 

 an undulating line. 



Genus. Drepanocekus. 

 Maxillae lobo superior! magno concavo. 

 Palpi maxillares articulo extimo reliquis longiori elliptico. 



labiales cylindrici, articulo extimo brevissimo et fere 



obsoleto. 



Cnput masculum cornutum. 

 Prothorax masculus bicornis. 

 Scutellum tectum. 

 Elytra porcata. 



This insect \?> prima facie so different from Oniticellus, to which 

 it is most nearly related, and between which and Onitis it ought 

 to be placed, that it might rather be mistaken for a Trox. Its 

 most striking differences from Oniticellus are the long horns that 

 arm the head and prothorax of the male ; the peculiar sculpture 

 of the prothorax and elytra of both sexes ; and the absence of 

 a scutellum. Not having an opportunity of dissection I cannot say 

 whether it ought to be recorded as more than a subgenus.
