PIMPLA BISTRICTA, sp. nov. 



$ only. A dull, black species with the anterior legs, hind coxae, 

 the concave clypeus, underside of scape, and whole abdomen, somewhat 

 dark red or pale castaneous ; radices and tegulae and base of the 

 black stigma alone flavidous ; petiolar area subglabrous ; nietanotum 

 bicarinate ; front tibiae centrally inflated. Length, 14 mm. Ex- 

 tremely similar to P. spiloaspis and differing, besides its sparser pale 

 markings, in nothing but the longer legs, narrower abdomen with its 

 segmental apices not callose and postpetiole less centrally elevated ; 

 while in two points it is distinct from Plmpla as a whole viz., the 

 petiolar area is circular and cariuate, not trans -striate, with two distal 

 cariuae extending from its base to that of the nietanotum ; and the 

 front tibiae have their centre abruptly intumesceut with both extremi- 

 ties constricted.
