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

 antennal carinas ; frontal area indistinct ; antennal carina; short, 

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

 thickening slightly towards the apex; eyes comparatively large,

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

 the two together forming a convex gibbosity ; metanotum coiivex. 

 the basal portion slightly sloping forward, the apical portion much 

 longer and sloping backwards ; legs comparatively short and stout,

 broader posteriorly ; the ocelli are present and distinct though 

 small; the thorax is more massive; the mesonotum and scutellttm 

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

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