This interesting form was found by Mr. C. Steuart Betton. 

 It is one of the smallest of its genus, and is rather more elon- 

 gate than usual. The prothorax is convex, strongly rounded 

 at the sides and much narrowed in front. Tiie head from 

 the tip of the clypeus to the level of tlie eyes forms a triangle 

 of which the sides are straight and the apex almost a right 

 angle, but very slightly produced and curved upwards at its 

 extreme tip. The peculiar form of the clypeus is not, as in 

 the subgenera Ceratogoniaand Catagoaiaj a mark of the male, 

 being the same in both sexes.

This is the only black species of Empecamenta at present 

 described. It is also more thinly clothed with hairs than any 

 otiier species known to me, and the elytra, instead of being 

 simply irregularly punctured, are very coarsely rugose. The 

 eyes also separate it sharply from its congeners, being large, 

 prominent, opaque, and coarsely facetted. In other species 

 they are very shining, tiie facets being so small as to be 

 hardly visible under a simple lens. 



To this genus also belongs Ahlahera variabilis, Fahr., 

 perhaps the nearest ally of E. nigra ; but, in addition to its 

 orange-coloured markings, it has paired rows of punctures 

 upon the elytra.
