DESCRIPTIONS OF NEW HYMENOPTERA. 445 



furrow. Legs black ; the apex of the coxae, the trochanters, and the 

 extreme base of the femora, white ; the apex of the anterior femora in 

 front and of the tibia more broadly, white ; the anterior tibise and tarsi 

 are fuscous in front. The second and third cubital cellules are almost 

 equal in length ; the transverse basal nervure is received near the 

 middle of the cellule, 



A larger species than T. melanopodus ; it has a more decided blue 

 tint ; the transverse basal nervure is received near the middle, not near 

 the apex, of the basal third ; the trochanters are white and the frontal 

 fovea is larger, deeper and longer than broad. 



BUSARBIA ALBIPES, SJJ. nov. 



Nigra, nitida, pedibus, linea pronoti, tegulis scapoque antennarum 

 albis • alis hyalinis, nervis stigmateque nigris. 9 . 



Long : 6 m.m. 



Habitat : Simla. 



Antennae black, the scape white, lined with black above. Head 

 smooth and shining ; the furrows bounding the vertex are wide and 

 deep ; the frontal area is depressed at the apex and bears a few longi- 

 tudinal strise ; the frontal area is largely depressed in the middle — 

 wide above, becoming narrowed below, — the apex of the clypeus and 

 the labrum fuscous. Thorax smooth and shining ; the edge of the 

 pronotum and the tegulse white. Legs clear white ; the apices of 

 the tarsi infnscated. Wings hyaline, a very little infuscated in the 

 middle ; the first transverse cubital nervure is largely buUated • the 

 first recurrent nervure is received at less distance than its own lenoth 

 from it. The back of the abdomen has a slight violaceous tinoe. 



This species comes near to B. viridipes, which differs from it in the 

 clypeus, labrum and base of the mandibles being broadly white ; the 

 pleurse are also marked with white, and the second cubital cellule 

 receives the recurrent nervure near the apex, not at the base as with 

 the present species. 



Selandeia trifoveata, sp. nov. 



Nigra, pedibus albis; apice tibiarum posticarum tarsisque postici» 

 nigris ; alis hyalinis, stigmate nervisque nigris. $ . 



Long : 5 m.m. 



Habitat : Simla. 



Antennae not quite so long as the abdomen, distinctly tapering 

 towards the apex, and densely covered with short, stiff pubescence ; the
