Hymenoptera from Northern India, 295 



and shining ; the apices of the segments pruinose ; the pygi- 

 dium has a few scattered punctures and hairs; the epipygium 

 is more closely and distinctly punctured and has a shallow 

 furrow on either side at the apex. 



Larra pygidialis, sp. n. 



Nigra, femoribus posticis rufis ; alis fusco-violaceis, cellula cubitali 



i2 a duplo longiore quam l a . $ . 

 Long. 17-1S mm. 



The scape of the antennae sparsely, the flagellum thickly, 

 covered with white hair; the second joint shining, sparsely 

 haired. Head shining, the front sparsely punctured and 

 covered with white hair. The face and clypeus closely punc- 

 tured (except on the apex of the latter) and thickly covered 

 with white pubescence. The tooth of the mandibles and a 

 large space before their apex rufous, and fringed below with 

 long pale golden hair. The palpi brownish and thickly 

 covered with white hair. Pro- and mesonotum minutely 

 punctured; the mesonotum thickly covered with fuscous 

 pubescence. Median segment minutely punctured ; its 

 middle from the base to the top of the apical furrow closely 

 transversely striated. Pleurae shining ; the furrows on the 

 mesopleurae distinct, the basal perpendicular one striated. 

 The metasternal area is thickly pilose ; there is a central keel 

 which reaches to the apex and is much stouter at the base ; 

 there is a narrower lateral keel which reaches to the middle 

 only. Legs thickly covered with white pubescence ; the 

 tarsal spines are rufous, as is also the base of the hinder 

 calcaria; the hinder femora are red, black at the extreme 

 apex. The costa and stigma are black ; the nervures are 

 fuscous ; the apical abscissa of the radius is very slightly 

 oblique ; the first cubital cellule is half the length of the 

 second ; the second recurrent nervure is roundly curved and 

 is received in the middle. Abdomen shining, pruinose; 

 the apices of the middle three segments depressed ; the 

 pygidium sparsely haired ; strongly irregularly punctured, the 

 basal punctures smaller, those on the middle and apex almost 

 running into striae ; the sides are furrowed; the outer edge 

 is sharply raised ; the sides of the segments are punctured 

 (except below) and are sparsely covered with brownish hairs. 



This is a larger species than L. bicolorata, with which it 

 agrees in coloration ; it may be known from it by the furrow 

 on the apex of the median segment not reaching to the apex, 

 nor originating at the top, by the middle of the basal part
