Nyasaland, and Angola.

Liserta. — Du River, Camp No. 3, August 1926. 
Ucanpa. — Entebbe, April 14, 1927. 
At our camp on the Du River this species was the mosquito most commonly 
found breeding in holes of cut tree trunks in the clearing, in which small quanti- 
ties of rain water had gathered (Nos. 472, and 473). In one ease it was associated 
with the larvae of A. aegyptt. Throughout West Africa it is one of the most 
common species breeding in rot-holes of living or dead trees (see Macfie and 
Ingram, 1923, Bull. Ent. Res., XIII, pp. 292-293). It is readily recognized by 
the five silvery-white spots of the dorsum of the thorax (two large ones about 
the middle; two smaller ones just before the bases of the wings; and one at the 
anterior margin). The hind tarsi bear white rings of very unequal length, that 
of the fourth segment the longest; the last segment is almost all black. 
A. apicoargenteus is a West African mosquito, known from Sierra Leone to 
Uganda. 
Aédes (Stegomyia) vittatus (Bigot) 
Culex vittatus Bigot, 1861, Ann. Soc. Ent. France, (4) I, p. 227 ( 9; Corsica).

(Not Culex sugens Wiedemann, 1828). Edwards, 1912, Bull. Ent. Res., III, pp. 9 and 375, 
fig. 1 (larva). 
Stegomyia brumpti Neveu-Lemaire, 1905, Bull. Soc. Zool. France, XXX, p. 9, fig. ( 9 1; Harar, 
Abyssinia). 
Reedomyia albopunctata Theobald, 1907, ‘Monogr. Culic.,’ IV, p. 262 ( 9; Sierra Leone). 
BrLcIan Conao. — Kinshasa (received from Dr. Duren, who bred the species 
from larvae). 
This species may be recognized by the four distinet white dots of the mesono- 
tum, the white bands of the abdomen, and the white ring a little beyond the 
middle of the hind tibiae. The segments of the hind tarsi have broad, subequal 
white rings and the last segment is all white. 
A. vittatus is widely distributed in the Ethiopian and Oriental Regions. 
Although originally described from Corsica, it has not again been found in the 
Mediterranean Subregion. It seems probable that Bigot’s type was wrongly 
labelled (Edwards, 1928, Encycl. Entom., Sér. B, II, Diptera, IV, p. 167).
