The form of the trilobed outline of the head renders this 

 species very easy to distinguish from almost all to which it 

 bears any notable general resemblance. It is nearest to H. 

 pinguis, Blackb., which has a similar trilobpd outline of the 

 head and a similar clypeus ; but pinguis differs from it by 

 numerous characters, especially the antennal structure (which 

 seems to furnish the most convenient character for 

 tabulation), the head notably smaller in proportion 

 to the prothorax, colour much darker, form notably 

 more depressed with more hindward dilatation, elytral 

 puncturation not at all of the squamose type, clypeus 

 and frons notably less near to forming an even plane. 

 Compared with H. agricola, Blackb., II. auricomus, Blackb., 

 is much smaller, its colour much lighter, its clypeus with a 

 continuous raised edging across the front, etc. The trilobed 

 outline of the head in agricola is fairly strongly denned, 

 though notably less so than in II. Sloanei, Blackb., and is 

 divided, with the middle lobe slightly less than half a lateral 

 lobe. Sloanei is easily distinguished from agricola by its 

 strongly rugulose elytra, etc.
