such as to whether they are freshly emerged or worn, fed or starved, as well 
as to the method of collecting and to their age in collections.! 
T’. secedens is strictly West African, extending from the Gambia to Uganda. 
Austen (1909) has recorded it from Liberia (Bafu Bay and Sino). It occurs 
over most of the Belgian Congo as far south as the Lubudi River; but it has 
not been taken in Upper Katanga. S. A. Neave (1915, Bull. Ent. Res., V, 
p. 130) states that he took near Mt. Mlanje, southern Nyasaland, four females 
and one male ‘‘of what appears to be a form of or perhaps a distinct species 
allied to T’. secedens Walk.” Since this is the only East African record, the 
identification is open to question.” 
Commenting upon the abundance of 7’. secedens in Ashanti, Graham (1909, 
‘Rept. Ent. Observ. Ashanti,’ p. 9) writes: ‘‘Herds of cattle driven along the 
Cape Coast road are sometimes accompanied by great swarms of these flies 
making a hissing noise like that made by a windstorm.”’

T. kingsleyi is strictly West African, being known from Sierra Leone, Libe- 
ria, the Gold Coast, and Southern Nigeria.

BELGIAN Conco. — Lubudi River (J. Rodhain). Hemptinne-St.-Benoit

A species apparently restricted to the Congo Basin. Whether it extends 
into Katanga appears doubtful. The specimens which I have formerly re- 
corded from that region (1913, Rev. Zool. Afric., II, 3, p. 455) were probably 
misidentified. Moreover, it is by no means certain that 7. claripes is not an 
extreme individual variation of 7’. secedens Walker.

bourg (Baugniet). 
These specimens have been compared with the type. 7’. lufirensis is known 
1 The horse-flies taken by Ghesquiére on the Congo River and referred by him to 7. gabonensis 
(Vanderyst, 1928, Bull. Agric. Congo Belge, XIX, p. 621), all belong to what I here call 7’. secedens. 
2 Austen’s (1926, Ark. f. Zool., XVIII B, No. 6, p. 3) more recent record from “Tanganyika 
Territory, Ituru District,” is based upon a confusion with the Ituri District, Belgian Congo, as I have 
explained under 7’. marmorosus.
