and none on tbe sternum and ocelli, the recurrent nervure 

 is interstitial and all the abdominal Segments are striated. 



Cheloninw. 



Odontosphaeropyx, gen. nov. 



Abdomen longish oval, rounded above, with 3 distinctly 

 separated segments, tbe 3 d longer than the 2 nd , but shorter 

 than the basal 2 united, its apex broadly rounded, unarmed, 

 Apex of clypeus in the centre armed with a stout 

 triangulär tooth, longer than it is wide at the base; the 

 sides on either side of it are aemicircularly incised and 

 depressed. Wings with 3 cubital cellules; the recurrent 

 nervure is received in the l st ; the transverse basal nervure 

 is large, dilated into a sort of stigma, which occupies its 

 entire apex. Radial cellule short, not projecting much 

 beyond the cubital cellules. Eyes bare; malar space about 

 three fourth of their length. Occiput not margined above, 

 margined below from near the top, widely, deeply, roundly 

 incised. Parapsidal furrows wide, deep. Scutellum round- 

 ly convex. 



The type of this genus is a larger and stouter insect 

 than is usual with the Family. In the arrangement of 

 Szepligeti it would come in near Sphaeropyx and Acampsis, 

 from both of which it may be known by the toothed, 

 roundly incised apex of clypeus and by the dilated apex 

 of the transverse basal nervure. 



Odontosphaeropyx ruftceps, sp. nov. 



Rufous, the antennse, mandibles, the lower edge of the 

 clypeus and the central tooth, the back of the basal 2 

 segments of the abdomen except the sides broadly, and the 

 3 rd except for a much narrower red line on the basal three 

 fourths of the 3 rd , on the lower edge. Legs coloured like 

 the body, except that the femora are infuscated. Wings dark 

 fuscous, the base hyaline to the base of the dilated top of the 

 transverse basal nervure; there is an oblique hyaline cloud
