marginal carinae ; second tergite broader than long, with a tri- 

 angular area at the middle of the basal margin, the apex of the 

 triangle reaching beyond the middle of the segment, the base occupy- 

 ing not more than half of the basal margin, the triangle margined by 

 a smooth groove on each side, an oblique lateral groove on each side 

 of the segment, second suture smooth. Third tergite with a very 

 small area at each of the anterior angles ; the whole abdomen smooth 

 and shining. First abscissa of the cubitus strongly curved near 

 the base ; radius originating close to the middle of the stigma.

The eyes are not quite as large as in typical species of

This genus is mainly Malayan, though several species 

 occur in Africa. There seems to be only one Australian 

 species.
