aljout twice as long as the scape. A narrow groove with a 

 marginal carina along both the inner and outer margins of 

 the eyes ; the front opaque^ with a median carina almost 

 reaching the anterior ocellus, the region round the ocelli and 

 the vertex reticulate. Posterior ocelli a little further from 

 the eyes than from each other. Pronotum transverse, 

 sharply produced outwards and forwards at the anterior 

 angles ; mesonotum and the upper half of the mesopleurse 

 coarsely reticulate; scutellum sparsely punctured, with a 

 transverse row of deep closely set punctures a little before 

 the apex ; median segment strongly margined, with two 

 longitudinal carinse near the middle from the base to the 

 apex and two oblique carinas on each side, the space between 

 the carinse obliquely striated, the posterior truncation of 

 the segment abrupt and transversely rugulose. Abdomen 

 subsessile, smooth and shining. Second cubital cell subtri- 

 angular, almost pointed on the radial nervure ; recurrent 

 nervure received at about five-sixths from the base of the 

 first cubital cell. Cubitus of the hind wing interstitial with 

 the transverse median nervure. Radial cell of the fore wing
