Not very close to any other species known to me, except 

 H. 'pauper, but to a casual glance of very ordinary appear- 

 ance, with much general resemblance to those small 

 obscure-looking species which I have placed in the latter part 

 of Group. VIII. (H. parvulus, Macl., etc.) — a resemblance 

 which is shared by H. infuscatus, Macl., and several others 

 near it in the tabulation. The sculpture of its dorsal surface 

 and most of its other characters are much like those of H. 

 borealis, Blackb., but it is very distinct from that species by 

 the shape of its prothorax (strongly narrowed in front and 

 with the sides strongly rotundate-dilatate behind the middle) 

 and by the notably wider and less prominent middle lobe of 

 the trilobed outline of its head ; its trilobed outline being 

 very feeble and not divided, with the middle lobe about three- 

 quarters of a lateral lobe in size.
