 Wilder). 



A small species of very narrow form, the 

 elytra of which bear three complete lateral striae on each side, the rest being 

 entirely obsolete. It closely resembles P. tenuimargo, Schm. (Seychelles Is.) 

 and P. rosselense, Lewis (Louisiade Archipelago), but is rather more elongate 

 than either and differs- conspicuously in its pygidium, which is not convex, 

 with its apex incurved, but flattened and prominent, very strongly punctured 

 and a little hollowed on each side. The head has a straight clypeal stria,
