Genera and Species of Hymenoptera. 503 



Iearia tinctipennis, sp. n. 



Ferruginea ; abdomine, coxis femoribusque posticis nigris ; alia 



fusco-byalinis, nervis stigmateque nigris. $ . 

 Loug. 21 mm. 



Hal. Khasia Hills. Coll. Rothney. 



Antennas rufous ; the basal joints of the flagellum darker 

 above. Front and vertex shagreened, thickly covered with 

 fulvous pubescence ; the part between the antennas projecting, 

 keeled in the middle. Clypeus shining, sparsely punctured, 

 thickly covered with fuscous hair ; the apex in the middle 

 forming a distinct tooth. Mandibles pilose, sparsely and 

 distinctly punctured; the teeth deep black. Thorax rufous; 

 the edges of the mesonotum, a line down the centre, the apex 

 of the mesopleura?, the part along the sutures, the breast, the 

 base of the metapleurse, the central furrow of the metanotum 

 and its sides black. The entire thorax is thickly covered 

 with short pubescence, which has a fulvous tint on the meso- 

 notum ; the, pleura? are shagreened ; the metanotum obscurely 

 transversely striated. The nervures are paler, more testa- 

 ceous in tint than the costa and stigma; the second cubital 

 cellule above is distinctly wider than the space bounded by 

 the two recurrent nervures ; the space bounded by the second 

 and by the third transverse cubital nervures is slightly but 

 distinctly wider than the space enclosed by them. Legs 

 coloured like the thorax ; the coxse, the hinder trochanters, 

 and the hinder femora blackish ; the four hinder tarsi are 

 infuscated. Petiole longer than the second segment, the node 

 becoming slightly and gradually narrowed towards the apex; 

 the third segment is one third longer than the fourth, which 

 is equal in length to the fifth. 



The differences between this species and I. fulvinerva may 

 be best shown in synoptical form : — 



Petiole rufous ; wings yellowish ; the fourth abdo- 

 minal segment distinctly longer than the fifth . . fulvinerva. 



Petiole black ; wings not yellowish ; the fourth abdo- 

 minal segment equal in length to the fifth tinctipetmis. 



The petiole is stouter and more distinctly dilated towards 

 the apex, the scutellum is not furrowed down the middle, and 

 the propleui83 not striated as in fulvipennis. It is one of the 

 largest of the Indian species.
