the apex of the scutellum. With the exception of some ahnost 

 obsolete punctures on the head, the entire upper surface is devoid 

 of puncturation even under a strong lens. The granules on the 

 elytra are rather closely set throughout (most so near the suture), 

 and. have a general tendency to a linear arrangement, here and 

 there some granules (more or less exceeding the average in size) 

 running in well defined longitudinal rows ; the most conspicuous 

 of which are one about the middle of the disc (which is quite 

 obsolete near the apex) and another half-way between it and the 

 suture (this latter row being obscurely continued almost to the 

 apex). The extreme margins of prothorax and elytra are a little 

 rufescent. The elytra at the extreme apex are dehiscent and 

 separately end in an obtuse point, but this may not be always the 

 case as they are not quite symmetrical in the example before me.

Resembles H. pallidus, MacL, (of which I have an example 

 named by its author) but narrower and more parallel. It differs 

 also in the right-hand anterior projection of the prothorax being 

 above the left-hand projection at the apex (I am not at all sure of 

 the value of this character), and in the space enclosed by the 

 anterior projections of the prothorax being scarcely wider than 

 long ; the elevation in front of the middle of the base of the pro- 

 thorax is less spiniform, — resembling a sharp conical tubercle
