head is impunctate except for a narrow basal space which is 

 closely punctured ; the prothorax is sloping for nearly three-fourths 

 of the length in the central part and still more laterally, it has in the 

 centre a broadly emarginate lobe ending on each side in a sharp, 

 triangular tubercle projecting over the sloping part, the sides are 

 impressed from apex nearly to the base, and the posterior part is 

 thus exceedingly narrow, but a little broader behind the median 

 lobe, the supra- marginal lateral impression is broad and very 

 distinct, and the surface is nearly impunctate except in the anterior 

 median part, along the anterior angles, and also along the basal 

 margin ; elytra convex, distinctly punctato-Striate, intervals very 

 vaguely aciculate. 



Female : Head broadly emarginate in front as in the male, also 

 smooth but more broadly punctured in the posterior part along the 

 base, it bears also a horn, but the horn is short, 2f mm., much 

 curved, and has no trace of a triangular tooth in the posterior part, 

 and is not ensiform; the prothorax is much more declivous in 

 front, the posterior part being as long as the declivous part, which 

 is only slightly impressed and is surmounted by two small median 

 tubercles set close to one another, the supra-marginal impression is 

 broad and deep and the surface is closely and deeply punctured 

 except for a narrow impunctate band running from the anterior 

 angle round the base, this smooth space is a little broader in the 

 median part above the base ; elytra as in the male. 



Length 18-22 mm. ; width 11-12 mm.

Male : Black, sub-opaque on the prothorax, elytra duller black, 

 nearly opaque ; clypeus deeply emarginate in the centre and with 

 the angles of the emargination sharp and projecting; genae in a line 

 with the clypeus laterally ; head with a compressed incurved horn 

 varying in length from 3 to 4^ mm. and strongly hamate behind at 

 the base, behind this cephalic horn there is a faint trace of a trans- 

 verse carina, the sides of the clj-peus and the genae are closely but 

 not deeply punctured, but the anterior part is distinctly smooth ;
