 bifurcate. Wings with mediastinal vein 4-ramose, radial vein bifurcate from 

 bej'ond the middle, lo-ii costals, ulnar vein with 3 complète and 2 incom-

A large number of both sexes in ail stages of development. 

 I know of no other species of this genus with micropterous maies 

 and females. In the larvae the fuscous pronotal vittae extend into 

 the other two thoracic tergites and the abdomen is heavily mottled 

 with fuscous. 



In the key to the African species of Ischnoptera published in 

 Mém. Soc. eut. Belg., XV, p. 230 (1908) this species will foUow 

 /. Longstaffi and /. punctifrons, but is distinguished from both by 

 the verv short supra-anal lamina of the maie.
