This may be distinguished from inexorahilis and transvaal- 

 ensis by the greater approximation of the eyes on the vertex, 

 especially in the male; and by the yellower colour of the 

 wings.

Long., 6 2 , 1^-13 mm. 



^ . Clypeus very broadly subtruncate at the apex ; vertex 

 not distinctly punctured ; eyes separated on the vertex hy a 

 distance equal to the combined length of the two basal joints 

 of the flagellum. Galea short, very broadly rounded at the 

 apex ; second and third joints of the labial palpi short, sub- 

 equal. Median segment about half as long again as the 

 scutellum, the longitudinal sulcus almost obsolete. Seventh 

 tergite rather broadly subtruncate at the apex ; the eighth 

 sternite rather broadly emarginate, the apical angles strongly 

 produced. Third cubital cell long, extending much beyond 

 the apex of the radial cell, at least three-quarters of the 

 length of the second on the cubitus. A variety has the 

 abdominal fasciae dull golden, 



$ . Distance between the eyes on the vertex as in the 

 male ; pygidial area triangular, acute at the apex ; second 

 sternite subopaque, closely microscopically punctured ; basal

 as below, leaving only a black ring at the joints. 



$ . The pygidial area very distinctly broader than in the 

 typical form, broadly rounded at the apex.
