 Stegomyia nigeria, Theo., Mon. Cul. I, p. 303 (1901). 



The type of S. nigeria is in very bad condition, but there is quite enough of it 

 left to show that it is the unmistakable S. fasciata. It was described from 

 a single specimen. In the fifth volume of his Monograph, Theobald records a 

 specimen of S. nigeria from Bailundu, Angola : this on examination proves to be 

 a typical, if somewhat rubbed, specimen of S. pseudonigeria. 



The legs of S. fasciata distinguish it from all the other species, as the femora 

 all have a narrow white line running almost their entire length. The abdomen is 

 usually black, with basal and often also apical whitish bands on all the segments ; 

 in one desert variety, however, the general hue is light brown instead of black. 



S. fasciata is common throughout the warmer parts of the world. From the 

 fact that a number of African species are rather nearly related to it, a guess may 

 be hazarded that its original home was in this region.

(1905). 

 Reedomyia albopunctata, Theo., Mon. Cul. IV, p. 262 (1907). 



Dr. Neveu-Lemaire gives such good figures and description of his species 

 (Arch. Parasit. X, 1906, pp. 261-265) as to leave no doubt that it is the same as 

 S. sugens, Wied., as interpreted by Theobald. He finds that the hind claws of 

 the male may be toothed or not, or one toothed and the other not. The 

 types of R r albopunctata are in poor condition, but quite recognisable. 



The species can be easily recognised by the six white spots on the thorax, and 

 also by the white bands near the apices of the femora and near the bases of the 

 tibiae.

3. S. pseudonigeria, Theo., Mon. Cul. V, p. 166 (1910). 



S. ivellmani, Theo., Mon. Cul. V, 163 (1910). 

 The name pseudonigeria is used for this species, because Danielsia wellmani, 

 Theo. (1905), known only from the female, may be a Stegomyia and not an Och- 

 lerotatus. In any case it would be well not to duplicate specific names in the 

 A'edes group.
