 characters of abdomen, by the large, light-coloured pterostigma and 

 conspicuously brownish tips of wings, as well as by the lateral 

 abdominal blackish lines a little distant from the lateral carinae, and

Not a common species, but very widely distributed in Eastern 

 Africa from Egypt (Cairo) to Natal, and also found in West African 

 stations (Sierra Leone, Kamerun and the Congo).

A genus of comparatively small to very small forms, conspicuous 

 by coloured wings, short depressed abdomen and the curious sinuate 

 course of the costal vein in its ante-nodal part. One of its species is 

 certainly a characteristic insect of the Ethiopian faunal region, and 

 present practically in every collection brought from inter-tropical
