Allied to Erytenna ; but without ocular lobes, and the an- 

 terior and intermediate tibia? having two spiu-s at the apex, 

 the inner one the ordinary mucro, the other being claw-shaped 

 and arising witliin the rim of the apex, as in many Crypto- 

 rhynchinffi. The species here described is not unlike Sihinia 

 arenarue,

The coarsely faceted eyes and subtruncated base of the
