a specimen answering to this description, but the numerous specimens of Aedomyia 

 received from various parts of Africa show a good deal of variation in the amount of 

 white on the proboscis and palpi, and I therefore incline to believe that Neveu- 

 Lemaire only described an unusually dark specimen of the species which is widely 

 distributed in Africa. This species I have previously identified with the Oriental 

 A. catastida ; there are, however, slight but apparently constant differences between 

 the two, and I therefore propose to use Neveu-Lemaire's name for what I believe is 

 likely to prove the only African species of the genus. 



Fie. 10. Male genitalia of Aelomyia seen from below, with tip 



of clasper further enlarged : — (a) A. squamipennis, Arr., from 



British Guiana ; (6) A. catasticta, Knab, from Sarawak ; (c) 



A. africana, N.-L., from Nigeria. 



A. africana differs as follows from A. catasticta : — It is on the average distinctly 

 smaller ; the wings have a well-defined clear yellow patch at the base just below the 

 costa, in which no darker scales are included ; the yellow patch on the mesonotum 

 is more sharply defined and rather larger, and its sides are not indented by patches of 

 dark scales ; the claspers of the male genitalia are somewhat narrowed instead of 

 shghtly expanded towards the tip, and their terminal spine is divided into about 15 

 instead of about 20 teeth (fig. 10 c). 



Figures of the male genitalia of A. catasticta and A. squamipennis are given for 

 comparison. It is possible that A. catasticta is the same as the Australian A. venus- 

 tipes, but this is not likely, since Taylor speaks of white scales being present on most of 

 the joints of the female antennae, whereas in the three species known to me only the 

 first two antennal joints bear scales.
