 The labrum of this species is very peculiar, being ex- 

 tremely deeply emarginate and projecting from the perpen- 

 dicular front face of the clypeus considerably at its ends, 

 while its middle part is in contact with the front face of 

 the clypeus and distinguishable only by a suture. The cilise 

 fringing the prothorax and elytra are longer and closer than 

 in most species of Heferonyx.
