from that of the clypeus. The prothorax is nearly twice as wide 

 as long, the base slightly more than half again as wide as the front, 

 which is rather strongly emarginate with sharp prominent angles, 

 the sides gently arched, the hind angles quite rounded off, the base 

 evidently bisinuate and moderately lobed hindward in the middle. 

 The puncturation of the elytra is rather fine and lightly impressed, 

 not very close, very squamose in appearance, the transverse 

 wrinkling well marked but tine, the lateral fringe normal, the 

 apical membrane fairly defined. Of the commoner species perhaps 

 H. consians comes nearest to this in respect of elytral puncturation, 

 but the prothoracic sculpture resembles that of R.ffdvo-hirtiis snid 

 crassus, though evidently finer than in either of those species, 

 and a little more sparing than in the former. The under surface 

 and legs are as the same parts in II. crassus, except that there is a 

 more evident impunctate space on the antero-internal part of the 

 hind coxse, and that the external teeth of the front tibiae are more 

 robust, the uppermost being very fully half as large as the second, 

 and the external outline of the tibia from its base to the apex of 

 the uppermost tooth being gently concave.

Very closely allied to the preceding two species and also to II. 

 piger. It differs from them as follows : — from H. piger by its 

 polished and smoothly (and more sparingly) punctulate labrum, 

 the much less close puncturation of its surface, and other 

 characters ; from H. crassus by its wider prothorax (not much
