$ . Flavo-ochracea ; alis hyalinis, apice et in cellnla cubitali secunda 

 infumatis, v^enis testaceis ; clypeo convexo, latitudine tequilongo, apice 

 late truncato ; mesopleuris bitnbercnlatis ; segraento mediano area baaali 

 sparse punctata ; segmento ventrali secundo area basali elevata nulla. 



S. Feminte similis; flavus ; llagello segmentisque abdominalibus apice 

 angnste pallide ferrugineis ; mesonoto, vertice, segmentoque mediano basi 

 ssepe nigro-mactilatis ; clypeo modice producto, apice truncato ; mesopleu- 

 ris hand tuberculatis. 



Long. 5 , 12 nun. ; c? , 10 mm. 



5. Clypeus as long as broad, convex, broadly truncate at the apex. 

 Antennae inserted more than twice as far from the anterior ocelbis as 

 from the base of the clypeus, second joint of the flagelhim less than half 

 as long again as the third. Eyes diverging very slightly towards the 

 clypeus ; the posterior ocelli more than half as far again from the eyes as 

 from each other. Pronokim not depressed in the middle ; mesoplexirce 

 with two small tubercles ; first abdominal segment more than half as broad 

 a^ain as long ; second ventral segment without a raised area at the base ; 

 pygidial area more than twice as long as the greatest breadth, slightly 

 broadened towards the middle, half as broad again at the base as at the 

 apex. Closely but not coarsely punctured, most sparsely on the mesono- 

 tum and scntellum -, the enclosed area at the base of the median segment 

 very sparsely punctured, with the usual median groove. First recurrent 

 nervure received at one quarter from the base of the second cubital cell. 



S . Clypeus convex, a little longer than broad, shining and very 

 sparsely punctured, produced and rather narrowly truncate at the apex.' 

 Mesopleur^ not tuberculate. Antenna inserted about half as far again 

 from the anterior ocellus as from the base of the clypeus ; the apical joint 

 of the flagellum strongly curved, a little longer than the penultimate. First 

 abdominal segment as broad as long, with a slight depression on the middle 

 of the apical margin ; pygidial area nearly twice as long as the greatest 

 breadth, slightly narrowed to the apex. 



In both sexes there is a small fuscous spot on the petiole of the second 

 cubital cell.
