Fossorial IJi/menoptera from the Khasia IHlls. 67 



Pseudagenia montanata, sp. u. 



Nigra, femoribus posticis rufis ; alis fere hyalinis, nervis nigris, 



cellula cubitali 2^ longiore quam 1*. $ . 

 Long. 13-14 mm. 



Face and clypeus densely covered with silvery pubescence ; 

 the sides of the clypeus oblicpie ; the apex depressed, smooth, 

 and shining ; the base of mandibles thickly covered with 

 silvery pubescence. Palpi black, covered with silvery pu- 

 bescence ; the apex of mandibles piceous. Eyes scarcely 

 converging above. Thorax thickly covered with silvery pubes- 

 cence; scutellum and postscutellum aciculated. Median 

 segment strongly, somewhat irregularly, but not very closely, 

 transversely striated ; the basal part broadly, but not deeply, 

 furrowed down the middle. Pleurae pruinose ; the oblique 

 furrow on the mesopleuraj narrow, but distinct; the part of 

 the metapleurae above the furrow is obliquely striated. Legs 

 black, pruinose ; the hinder femora, except at the extreme 

 base and apex, red. Wings hyaline, with a slight fuscous 

 tinge : the first cubital cellule is distinctly shorter than the 

 second above and beneath ; the first transverse cubital 

 nervure is roundly curved ; the transverse median ncrvure is 

 widely remote from the transverse basal ; the accessory 

 nervure in the hind wing is shortly appendiculated. The 

 wings have a slight, but distinct, tulvous-violaceous tinge. 

 The tibiae are slightly, the tarsi more thickly spiuose. Tegulse 

 black. The abdomen is as long as the thorax; the base of 

 the petiole is distinctly narrowed ; the apical segments and, 

 to a less extent, the basal are densely pruinose. The upper 

 part of the propleura is broadly rounded ; this dilated part 

 is bordered at the apex below by a curved furrow, the part 

 below this is roundly dilated, but not so much as the lower 

 part. The apical part of the pronotum is transverse in the 

 centre at the base. The claws are toothed at the base. 

 Comes nearest to P. stulta, Bingham.
