ON SOME NEW GENERA AND SPECIES OF 

 HYMENOPTERA. 



By p. Cameron. 



CHALCIDIDiE. 



(Continued from p. 111.) 



Oncochalcis, gen. nov. 

 Antennge short, thick, eleven-jointed, the scape not reaching to the 

 ocelU ; they are widely separated from the mouth. Mandibles 3-den- 

 tate ; the teeth small, the central smaller than the others, almost 

 obsolete. Temples short ; the occiput transverse. Parapsidal furrows 

 distinct, curved. Scutellum large, its apex broadly rounded, with a 

 short projecting border. Metanotum short, reticulated, its apex with 

 a steep slope. Abdominal petiole sessile, the ovipositor short. Hind 

 femora largely thickened, beneath minutely dentate. Middle tibias 

 spined. Submarginal vein twice the length of the marginal, the post- 

 marginal half the length of the marginal, the stigmal vein short, about 

 twice longer than broad. The mandibular teeth are small and indis- 

 tinctly separated ; the first abdominal segment is about one- third 

 shorter than the others united ; the scape of the antennae is half the 

 length of the flagellum ; the femoral teeth in one species are distinct, 

 in another indistinct.
