Pimpla, though the erroneously short terebra lends it somewhat 

 the aspect of Itoplectis cvrticmtda, Kriech. Both this and 1 he- 

 preceding species appear remarkahly closely allied to P. i

cJ $ . Head short and somewhat strongly constricted behind 

 the eyes ; frons and face hardly nitidulous, the former trans- 

 versely subrugulose, the latter shallowly punctate ; palpi piceous. 

 Antennce long and slender, filiform and immaculate. Thorax 

 black; mesonotum shining, finely and shallowly punctate ; meso- 

 pleurae finely, evenly and diffusely punctate, becoming subrugose 

 below ; metathorax strongly rugose-punctate, with the areola 

 apical ly; entire and laterally distinctly carinate ; petiolar area 

 basal ly rugose and apically nitidulous ; metapleurae closely and 

 finely strigose ; spiracles elongate. Scutellrm immaculate (or 

 apically flavous). Abdomen closely and coarsely punctate basally, 

 more finely towards the nitidulous apex ; tubercles obsolete ; 

 apices of the segments not broadly elevated and nitidulous, the 

 apical ones often narrowly pale ; terebra half the length of the 

 abdomen, with the valvulro shortly pilose. Leys red, with the 

 coxae black ; hind tibiae, often the femora, and at least the apices 

 of the tarsi nigrescent, with their tibia3 usually narrowly pale- 

 banded before the base. Wings a little clouded, with the fenestne 

 very distinct ; stigma nigrescent, with its base somewhat pale ; 

 nervellus intercepting far above the centre of the first recurrent 

 nervure. 



Length 9-15 millim.

 7000 ft. (Col. Nurse, v. 1897 and in Pusa coll. x. 1907). 



In Europe it is an essentially northern species, common in 

 Scandinavia but seldom met with in the central countries. As 

 compared with European specimens, the Indian <3 differs only in 

 its distinctly paler stigma, while the apex of the scutellum is 

 bright flavous in the $ ; both of which modifications have already 

 been noted as obtaining in the eastern representatives of European 

 species, under P. instigator. 



This species is very like P. iurionella?, and especially its var. 

 strif/iphwis ; but it is altogether stouter, with the hiud tibia3 at 

 most but narrowly pale-banded. I have seen no Oriental speci- 

 mens with any trace of the pale band. From P. instigator it 

 differs in having the face much more closely, and in the elevated 

 centre confluently, punctate, with short grey pilosity; the palpi 

 with at most the two apical joints paler, the scape more strongly
