g . Head more or less cordate, the occiput emarginate, generally 

 broader than the anterior margin of the head ; mandibles broad, 

 triangular, the masticatory margin equal in length to the outer 

 margin, the former armed with numerous small teeth ; elypeus 

 broad, convex in the middle, extending angularly up between the 

 antennal carinae ; frontal area indistinct : antennal carinse short, 

 wide apart, parallel ; the scape moderately long, the flagellum 

 thickening slightly towards the apex ; eyes comparatively large, 

 placed in front of the transverse middle line of the head. Thorax 

 moderately broad, viewed in profile deeply emarginate at the 

 meso-metanotal suture ; the pro-mesonotal suture distinct but not 

 incised; the mesonotum convex, raised slightly above the pronotum, 

 the two together forming a convex gibbosity ; metanotum convex, 

 the basal portion slightly sloping forward, the apical portion much 

 longer and sloping backwards ; legs comparatively short and stout, 

 the calcaria pectinate, claws simple. Pedicel without a proper 

 elevated node, simply with an oval flat thickening in the middle ; 

 abdomen at base very much produced, raised and gibbous, over- 

 hanging the pedicel, posteriorly conical, with aii apical cloacal 

 aperture. 



$ . Closely resembles the , but the head is proportionately 

 broader posteriorly ; the ocelli are present and distinct though 

 small ;' the thorax is more massive ; the mesonotum and scutellum 

 nearly flat, very slightly convex; there is a slight constriction 

 behind the wings; the fore wing with a radial and one cubital 

 cell ; the metanotum broad, sloping obliquely back to apex, only 

 slightly convex, nearly flat. Pedicel very short, and together with 

 the abdomen as in the > .
