 angulate at its base. Sternum with the front coxse very 

 close to the gular margin. 



Tiie S narrower than the ? , the prothorax slightly less

Described from 15 S i and 8 ? ? . 



Closely allied to P. {Strophosimms) setifei\ Fhs., in which 

 the prothorax is much less strongly rounded at the sides, 

 the base and apex are truncate, and the lateral stripe is grey

 uniformly grey. 



Head separated from the rostrum by a very deep bisinuate

 median furrow extending to behind the eyes, and set with 

 subrecumbeut flattened setse ; the eyes very prominent and 

 strongly produced backwards, deepest distinctly behind the 

 middle, the orbits fairlj broad and very slightly projecting 

 on the posterior edge ; the gular area densely clothed with 

 bi'oad scales. Rostrum evidently shorter tiian its basal
