Type, P. htguhris, Fabr. 



Ranrje. Palaearctic region, and higb elevations in the Oriental 

 region. 



Head large, subquadrate ; eyes prominent, ovate ; antennae 

 rather widely separated, inserted at the base of the clypeus, 

 transverse ; labriim small and triangular ; mandibles stout, their 

 apex dentate ; thorax broadly oval ; the mesonotum and median 

 segment strongly convex, gibbous ; wings with one radial and two 

 cubital cells, the radial and 1st cubital cells subequal, but the 

 latter oblong, the 2nd cubital cell nearly square, about half the 

 length of the 1st cubital cell, each of the cubital cells receives 

 a recurrent nervure ; legs moderately long, slender, spinose ; 

 abdomen M"ith the ventral plate of the basal segment forming a 

 long slightly curved petiole, which is longer than the 2nd 

 abdominal segment, the rest of the abdomen lanceolate ; the apex 

 of the abdomen with a single spine ( d' ) or canaliculate ( $ ). 



The only Indian species at present known comes from an 

 elevation of 7000 ft. in the Himalayas, and nothing is on record 

 about its habits, which, however, probably resemble those of the 

 European species. The latter nest in holes in old posts and rails, 

 and provision their larvae with Aphides.
