916 REPORT OF THE HARVARD AFRICAN EXPEDITION 
T. fasciatus and its varieties are almost restricted to the West African Sub- 
region. The southernmost certain record is based upon a specimen obtained by 
S. A. Neave on the Dikulwe River in Katanga. Miss Ricardo has listed 7. 
fasciatus from Damaraland, on the strength of a specimen in the South African 
Museum, but its occurrence in that locality appears open to question. I also 
consider J. Lewis’ record of this species from the Rovuma River (1887, Societas 
Entomologica, II, p. 49) as erroneous. 
Tabanus brucei Ricardo 
Tabanus brucei Ricardo, 1908, Ann. Mag. Nat. Hist., (8) I, p. 268( 9; Ankole, Uganda). Austen, 
1909, ‘Illustr. African Blood-Suck. Flies,’ p. 81, Pl. VI, fig. 41 ( ¢). 
Breute1an Conco. — Ruwe; Mfupgwe to Kalumba; mid-Lualaba (8. A. 
Neave). Sampwe (Van den Heuvel). Between Kwesi and Kilo (L. Bayer). 
Lomami (J. Schwetz). 
T. brucet appears to be a species of the savannas of Central Africa, extend- 
ing from Uganda westward along the edge of the Congo forest as far as the 
Lower Congo (Kisantu) and southward over Upper Katanga to Lake Bangweolo 
and the Chambezi River in Northern Rhodesia. 
Tabanus africanus G. R. Gray 
Tabanus africanus G. R. Gray, 1832, in Griffith, ‘Cuvier’s Animal Kingdom,’ XV, p. 794, Pl. CXIV, 
fig. 5 ( 9; type locality unknown). Austen, 1909, ‘Illustr. African Blood-Suck. Flies,’ p. 81, 
Pl. Vi, fe. 42:0 9). 
Tabanus latipes Loew, 1860, ‘Dipteren-Fauna Siidafrikas,’ p. 36 ( 2; Cape of Good Hope). Not of 
Macquart. 
BELGIAN Conao. — Uele River, one female (J. Rodhain). Kayumbi; mid- 
Lufira River (S. A. Neave). 
T’. africanus, which has often been confused with 7’. latipes Macquart, occurs 
over the entire Ethiopian Region from the Gold Coast to the White Nile, Somali- 
land and the Cape Province. 
Tabanus latupes Macquart (1838, ‘Dipt. Exot.,’ I, 1, p. 119; 9; Senegal) 
has been recorded from the Belgian Congo, without definite locality, by Surcouf 
(1911, Rev. Zool. Afric., I, p. 23). I have seen no specimen from that territory 
and I regard the above record as doubtful since 7’. latipes was generally confused 
with 7. africanus, until Austen pointed out the differences. I have a female of 
true 7’. latipes from the Upper Volta River, French Sudan. 
Tabanus ruwenzorii Ricardo 
Tabanus ruwenzorii Ricardo, 1908, Ann. Mag. Nat. Hist., (8) I, p. 332 ( ¢; Mubuku Valley on the 
eastern slopes of Mt. Ruwenzori, between 5,000 and 7,000 ft., Uganda). Austen, 1909, 
‘Tilustr. African Blood-Suck. Flies,’ p. 118, Pl. XI, fig. 81 (9). 
BELGIAN Conco. — Butagu Valley, on the western slope of Mt. Ruwenzori, 
at the altitude of 2,000 m., one female taken in the tent in a clearing close to the 
edge of the mountain forest, April 12, 1914. 
This species is known only from Ruwenzori, the nearby Mpanga Forest in 
Uganda, and Ankole, Uganda. It is decidedly a mountain form, occurring at 
altitudes between 5,000 and 7,000 ft.
