single female sent by Mr. King from the Sobat River at Nasser. 
It can at once be told from the other black-and-white mosquito with spotted thorax by 
the unhanded legs. 
The thorax has two pairs of brilliant silvery-white spots and another pair placed more 
laterally ; the abdomen of the female unhanded, but with basal white lateral spots, which in 
the male meet to form almost complete basal hands. 
The uniserrated fore and mid ungues have very small teeth. 
This species has so far only been recorded from Mashonaland.

single large $ taken by Mr. King in February, 1908, on hills to the east of Erkowit. 
It may he pointed out here that in quite fresh specimens there are six white thoracic 
spots, not four, as I mentioned in Vol. 1 of my Monograph. I have since re-examined Bigot’s 
type and find that there are just a few scales remaining, showing the position of the third 
pair of spots so clearly seen in the Sudanese specimen and those recently sent me from the 
Transvaal. 
The scutellum is clothed with only fiat scales and they are mainly silvery-white, hut 
some specimens may show a few dusky or ochreous scales in the middle of the mid lobe. 
The ungues of the hind legs are uniserrate, like the fore and mid. 
There is considerable variation in the abdomen; some specimens show very marked 
lateral white spots as well as the basal hands, others not at all. There may also he numerous 
white scales on the sides of the thorax and in front of the scutellum. 
The distribution is so far known to he as follows : Transvaal, very common ; Uganda; 
Gambia; Free Town; Sierra Leone; Mashonaland; Aden; Nubia; India; Corsica; as 
well as the Sudan.
