Allied to the preceding genus, but abundantly distinct by the 

 structure of the head and pronotum, the stylated eyes, the much 

 shorter rostruni, the differently shaped last female dorsal segment, 

 the position of the ventral glandular spots, the différent length of 

 the fore and middle tibiœ and the much longer metatarsus of the 

 hind legs. It ditïers from ail hitherto known gênera of this family 

 by having the pronotum arined with a long slender suberect spine 

 near the humerai angles.
