A very remarkable species; the extremely long laminae 

 of its antennae and the basal narrowing of its clypeus sug- 

 gest a doubt whether it ought not to be treated as the type 

 of a new genus. The antennal character, however, is repro- 

 duced in another species (11. cgregia, Backb.), which has a 

 normal clypeus, and so connects it with Haijlonycha. The 

 long pilosity of the sides and base of its pronotum is sugges- 

 tive of the species of my second group, but its pronotum has 

 not the wide lateral gutter of those species. The^ granula- 

 tion of the eyes is more distinct in this species than in most 

 of its congeners. It may be noted that in this species and all 

 the others of the Group V., in which I have indicated the 

 antennal club as having more than three joints, the club 

 might almost be called 5- jointed, as the 5th joint is slightly 

 lamelliform on its inner side, but so slightly that it seems more 

 convenient to regard it as appertaining to the stipes.

 Agrees with H. Mnvrirei, Blackb., in the extremely long 

 laminae of its antennal club, but otherwise more resembling 

 H. sinuaficolUs, Blackb., from which it differs by its much 

 smaller size, prothorax less strongly sinuate at the base, etc.
