rather strongly produced upwards in the middle, and the forehead 

 is armed with a longitudinal carina freely produced and truncated 

 in front. The prothorax is more convex and less contracted in

Type in the British Museum. 



In the peculiar differences of form and colour between the two 

 sexes this species shows relationship only to H. vintahilis, Hope, 

 from which it is quite easily distinguished. It is larger and has 

 less distinctly costate elytra, besides which the sternal process, 

 although short, is much less so than in that species, and the 

 clypeus is longer and quite differently shaped both in male and 

 female.
