apex, more than three times as broad at the base as at the apex, about 

 half as long again as the greatest breadth. Closely bnt not very coarsely 

 punctured ; the enclosed area at the base of the median segment smooth, 

 obliquely striated in the corners, with very short strife on the sides and 

 a deep median groove. First recurrent nervure received just before one- 

 third from the base of the second cubital cell. 



Habitat. — Shadipali, Sindh {Comber). 



In addition to colour differences this species may be distinguished from 

 C. tristis Cam. by the much broader pygidial area, and from C. pulchm 

 Cam. by the shallower and less angular emargination of the clypeus.

$ . Clypeus much broader than long, widely and rather shallowly 

 emarginate. Antennie inserted nearly half as far again from the anterior 

 ocellus as from the base of the clypeus, the second joint of the flagellum 

 very slightly longer than the third. Eyes parallel; posterior ocelli further 

 from the eyes than from each other. Pronotum not depressed in the 

 middle, rounded at the anterior angles; mesopleurte without tubercles. 

 First abdominal segment a little longer than broad ; second ventral seg- 

 ment with a raised area at the base ; pygidial area elongate ovate, a little 

 more than twice as long as the greatest breadth. Closely, but not coarsely 

 punctured ; the enclosed area at the base of the median segment shining, 

 with a few large punctures, the median groove deep. First recurrent 

 nervure received just before one-third from the base of the second cubital 

 cell. Wings iridescent. 



S . Clypeus as long as broad, narrowed towards the apex, the margin 

 rather narrowly truncate. Apical joint of the flagellum shorter than the 

 penultimate, scarcely curved. First abdominal segnuent much longer 

 than broad.
