244 F. W. EDWARDS—THE AFRICAN 
Genus PROTOMELANOCONION, Theo. 
Mon. Cul. V, p. 462 (1910). 
1. P. fuscum, Theo., Mon. Cul. V, p. 463 (1910), 
Although the generic characters will at once distinguish the male from all the 
related genera, the female is a very obscure insect, and might easily be mistaken 
for a small Culex, a Culiciomyia, or an Aedes. It perhaps bears the greatest 
resemblance to a Culiciomyia, since it has the same rim of white scales round the 
eye-margins ; but an examination with the microscope shows that the white 
seales are narrow-curved and not flat. P. fuscum Q can be distinguished from 
Culex grahami and its allies by the much longer bristles on the thorax. 
Genus LupLowt1a, Theo. 
Mon. Cul. IV, p. 193 (1907). 
Megaculex, Theo., Mon. Cul. IV, p. 282 (1907). 
Radioculex, Theo., Rec. Ind. Mus. LI, p. 295 (1908). 
Hispidimyia, Theo., Mon. Cul. V, p. 245 (1910), 
The essential characters of the genus are :—(1) the apparently 2-jointed 
3 palpi, of which the apical joint is swollen ; (2) the short fork-cells, especially 
the first ; (3) the rather peculiar shape of the marginal cell ; (4) the nearly bare 
posterior half of the wings; (5) the structure of the ungues, which is essentially 
the same as in Culex, but the larger claw on the anterior tarsi of the male always 
has two teeth; (6) the long antennae of the 3, usually longer than the 
proboscis. 
Ludlowia was founded on Mimomyia (?) chamberlaini, Ludlow, and Radioculex 
on R. clavipulpus, Theo. An examination of the types, however, shows that 
these are in reality one and the same species. Hispidimyia hispida, Theo., is 
very little different from L. chamberlaini, and Megaculea albitarsis, Theo., has 
all the essential characters of the genus.”*

* Since the above was in type I have had an opportunity of examining a male of Boycia 
mimomyiaformis, Newst. (vide p. 266), from Derri, N. Nigeria (J. J. Simpson). It evidently 
belongs to the subgenus Megaculex of Ludlowia. 
+ This species does not occur in Africa.
