from each other. Mesopleurce without tubercles ; first segment of tlie 

 abdomen about half as long again as broad, second ventral segment with- 

 out a raised area at the base ; pygidial area sparsely punctured, about 

 half as broad again at the base as at the apex, nearly twice as long as the 

 breadth at the apex. First recurrent nervure received at one-fifth from 

 the base of the second cubital cell. Closely and rather deeply punctured, 

 most coarsely on the abdomen ; the enclosed space at the base of the 

 median segment punctured, with indistinct obliqiie strise at the base. 



Habitat — ^Bombay (Coll. Rothney). 



As I have pointed out under C . jlavoficta, Bingham's description of the 

 female sulfhurea is taken ixom Jiavopicta . I doubt if his brief notice of the 

 male can be meant for the present species.

$ . Clypeus short and broad, deeply and very widely emarginate at the 

 apex, flattened. Antennte inserted about half as far again from the 

 ■anterior ocellus as from the base of the clypeus, the interantennal carina 

 low ; second joint of the flagellum nearly half as long again as the third. 

 Eyes very slightly diverging towards the clypeus ; posterior ocelli half as 

 far again from the eyes as from each other. Pronotum not depressed in 

 the middle ; mesopleurse without tubercles ; first abdominal segment nearly 

 twice as broad as long ; second ventral segment without a raised basal 

 ■area ; pygidial area rugulose, large, truncate at the apex, the sides almost 

 parallel, a little less than twice as long as broad. Head closely and finely, 

 thorax and median segment more sparsely punctured, abdomen and the 

 -enclosed space at the base of the median segment smooth. Wings sub- 

 liyaline, stigma testaceous, a fuscous cloud at the apex. First recurrent 

 nervure received beyond onethird from the base of the second cubital 

 cell. 



S . Clypeus a little longer than the greatest breadth, very broadly 

 rounded at the apex and armed with three minute teeth. First abdominal
