 The extraordinary antennae of this species with a club consist- 

 ing of five very elongate joints (longer than all the preceding 

 joints together) of which that nearest the base is a little shorter 

 than the rest distinguish it from all its described congeners 

 known to me. I do not think the character to be sexual inasmuch 

 as of flssiceps (which, has almost as elongate an antennal club though 

 only three- jointed) I have seen enough specimens to render the 

 presence of both sexes probable and I do not find any difference 

 in the antennae of different examples.

This species is allied to heterodactyla^ Germ, and soror, Blackb. 

 (from the other described species its closely punctured prothorax 

 in combination with a 7-jointed male antennal flabellum at once 

 distinguish it) from both of which it differs by the presence of
