cJ 5 . Head short and somewhat strongly constricted ])eliind 

 the eyes ; I'rons and face hardly uitidulous, the former trans- 

 versely subrugulose, the latter shallowly punctate ; palpi piceous. 

 Antenna', long and slender, filiform and immaculate. Thorax 

 black; mesouotum shining, finely and sliallowly punctate ; meso- 

 pleura) finely, evenly and diffusely punctate, becoming subrugose 

 below ; metathorax strongly rugose-punctate, with the areola 

 apically entire and laterally distinctly carinate ; petiolar area 

 basally rugose and apically uitidulous ; metapleura^ closely and 

 finely strigose ; spiracles elongate. Sctitellr.m immaculate (or 

 apically flavous). Abdomen closely and coarsely punctate basally, 

 more finely towards the uitidulous apex ; tubercles obsolete ; 

 apices of the segments not broadly elevated and nitidulous, the 

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

 abdomen, with the valvula) shortly pilose. Ler/s red, with the 

 coxfe black ; hind tibise, often the femora, and at least the apices 

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

 banded before the base. Winr/s a little clouded, -with the fenestra; 

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

 uervellus intercepting far above the centre of the first recurrent 

 nervure. 



Length 9-15 millim.

In Europe it is an esseutially northern species, common in 

 Scandinavia but seldom met with iu the central countries. As 

 compared with Europeau specimens, the Indian cJ differs only iu 

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

 bri<Tht 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. tiirioneUo', and especially its var. 

 strirjipleuris ; but it is altogether stouter, with the hind tibiae at 

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

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

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

 centre confluently, punctate, with short grey pilosity ; the palj)! 

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