posterior two oval or elongate, sometimes (as in the only Indian 

 sj^ecies as yet known) round ; antenna? sliort, llagfllum cyUndrical ; 

 mandibles incised in the middle of their outer margin, generally 

 dentate in the middle on their inner side. Thorax broadly oval ; 

 pronotum small, not nearly so broad as the mesonotum, transverse ; 

 median segment short, roundly truncate posteriorly, with a well- 

 marked space at base enclosed by convergent carina?. Legs stout, 

 spinose ; anterior tarsi ciliated, intermediate tibiae with one apical 

 spine, intermediate and posterior tibiae strongly spinose; claws 

 simp'e. Fore wing with one radial and three cubital cells, the 

 radial cell broadly obliquely truncate and with an a]3pendicular 

 cell ; the 1st cubital cell long, in all the species known to me longer 

 than the 2nd and 3rd cubital cells united ; the 2nd cubital cell 

 broadly triangular, very often petiolate, receiving both recurrent 

 nervures ; the 3l'd much broader on the radial than on the cubital 

 nervvu-e, the lower apical angle of the cell generally rounded, the 

 cubital nervure not continued beyond the apex of the cell. 

 Abdomen never petiolate, elongately conical, the margins of the 

 segments broadly depressed and constricted ; the end segment 

 with a well-developed pygidial area bare and punctured ; the 2ud 

 ventral segment obtusely produced in the middle. 



The European species P. flavipes, Fabr., is said to provision its 

 nest with various species of hymenopterous insects. Dufour gives 

 a list of 18 genera, species of which were found among the victims 

 of P. Jiavijjes.

" 6 • Length 8 mm. Black, head and thorax variegated wdth 

 pale yellow. Abdomen above, the apical segment excepted, with 

 pale yellow, slightly interrupted transverse bands. Legs for the 

 great part yellow. Wings hyaline. The front wide, strongly 

 convex ; the distance between the eyes nearly equal to the length 

 of the 2nd-6th joints of the fiagellum of the antennae. Antennae 

 somewhat thick, the joints beneath not produced. The 2nd and 

 3rd joints of tlie tlagellum equal, half as long again as the 1st. 

 The posterior ocelli normal, round, not flattened, the anterior 

 ocellus slightly smaller ; the distance between the ocelli and the 

 eyes not greater than between the ocelli themselves. Anterior 

 legs normal. Mesonotum shining, punctured. Median segment 

 distinctly punctured, with a broad medial groove. The 3rd ventral 

 segment without any gibbosity. The apical abdominal segment 

 with an acute spine on each side ; pygidial area distinct, somewhat 

 flat, in part rugosely punctured, and slightly carinated medially.
