of the right Side of one specimen a small spur issues 

 from the cross-vein from R^ to Ha + 3 ^nd passes a 

 short distance outwards. Such variations as these are 

 of common occurrence in Coniopterygidae and are of 

 little importance, though they may be of some signi- 

 ficance teratologically. 



The number of antennal joints varies from 35 to 

 38. 



The number of special setae on the anterior 

 femora averages 6, 



This species differs from previously described

 first of the occurrence of the genus in Africa. 



Coniopteryx (=Malacomyza Wesm.) aegyptiaca sp.n. 

 (Figs. 6-8) 



Entire body dark brown in dry specimen, wings 

 pale, but membrane tinged with fuscous. The whole 

 insect is covered with white, waxy powder. 



Head rounded ; compound eyes hemispherical, 

 black. Antennae moniliform, Qg-jointed ; the basal 

 joint largest, cylindrical, twice as long as broad; the 

 second joint also cylindrical and twice as long as 

 broad, but of smaller dimensions; the next four or five 

 joints have their length almost equal to Uieir breadth, 

 but more distally the antennal joints become longer, 

 and most of them are about one-and-three-quarters as
