near Stanleyville, Belgian Congo; but the specimen was almost certainly 
misidentified. It probably was a small female of 7. gratus, which species 
Laveran lists also from the same locality.

This species appears to extend over most of the Ethiopian Region. I agree 
with Austen (1912, Ann. Mag. Nat. Hist., (8) IX, p. 28) that it is most prob- 
ably identical with 7. wnilineatus Loew (1852, Ber. Ak. Wiss. Berlin, p. 658; 
9; Tette, Portuguese East Africa), which is known with certainty from the 
type only. Laveran’s records of 7. wnilineatus from French Guinea (1904, 
CoRR, Ac. Sel. Paris, CXXXIX, p. 660; 1907, loc: cit., CXLIV, p. 548) refer, 
of course, to 7. laverani, since one of his specimens was made the type of 
Surcouf’s species.

The only two records of this species from the Belgian Congo are a female 
from the Lufira River, Katanga (J. Bequaert, 1913, Rev. Zool. Afric., II, 
p. 461), and another from La Romée, near Stanleyville (Laveran, 1908, Bull. 
Soc. Path. Exot., I, p. 253). As neither of these specimens is before me now, 
I am unable to confirm the identification, which, at any rate in the case of the 
specimen of La Romée, appears somewhat doubtful. 
T. sufis appears to be essentially a species of the Sudan (Mauretania, Sene- 
gal, Gambia, Northern Nigeria, Chari River in French Equatorial Africa, and 
Anglo-Egyptian Sudan), extending into Lower Egypt. Patton (1920) and 
Austen (1923) record it from Mesopotamia, and Sureouf (1909) from Jeru- 
salem. Neave (1912, Bull. Ent. Res., III, p. 320) includes it in his list of the 
tabanids of Kenya Colony, but gives no definite locality for that territory.
