DESCRIPTIONS OF NEW HYMENOPTERA. 427 



Scape of antennae black, yellowish below ; the flagellum brownish, 

 black above. Head lemon-yellow ; the ocellar region and the central 

 part of the occiput, black. Face closely punctured and covered with 

 white hair ; the clypeus smooth, except-for a few punctures on the top. 

 Mandibular teeth black. There is an irregular mark on the base of 

 the mesonotum, an elongated mark — roundly narrowed towards the 

 base, the apex roundly incised — the sides and apex and two curved 

 marks, on the base of the median segment, extending from the 

 middle of the base to the spiracles, black. The mesonotum and the 

 scutellam are uniformly punctured allover ; the median segment is 

 more closely and strongly punctured; there is a transverse keel 

 above the apical slope. The pleurse are punctured like the upper 

 surface. Legs obscure fulvous, the posterior darker in tint ; the 

 basal joint of the hinder trochanters black ; the hinder tarsi are 

 infuscated. On the abdomen the middle of the petiole is broadly, — the 

 band incised in the middle behind — the middle of the second, third 

 and fourth segments broadly and the base of the others broadly, 

 black. 



The size and shapes of the black marks on the thorax vary.

Habitat : Simla. 



Scape of antennse black, yellow below ; the flagellum brownish, 

 darker above. Head black ; the face, oral region, the inner orbits — 

 broadly below — and the outer still more broadly, lemon-yellow. The 

 face is closely, but not strongly, punctured. Mesonotum black, except 

 for a yellow line bordering the central region ; the line is triangularly 

 dilated at the base. 



Scutellum yellow, the sides and base irregularly bordered with 

 black. The median segment has two large marks, extending from the 

 base to shortly beyond the middle, and irregularly narrowed at the 

 apex and with an irregular yellow mark in the centre near the base; 

 the apex is narrowly black. The whole thorax is closely and distinctly 

 punctured. Legs yellow ; the four anterior trochanters and femora
