Tabanus combustus Bigot (1891, Ann. Soc. Ent. France, LX, p. 368; 9; 
Assinie, Ivory Coast) has been recorded from the Belgian Congo by Surcouf 
(1907, Bull. Mus. Hist. Nat. Paris, XIII, p. 212). I have never seen a specimen 
from that territory. Moreover, the species seems doubtfully distinct from T. 
thoracinus Palisot de Beauvois. Surcouf, who saw the types, says that they 
differ from 7’. thoracinus “in the more reddish brown coloration, the broader 
frons, the darker color of the legs, and the black apex of the antenna.” In his 
description, however, he gives the same width of the frons (six times as long as 
wide) for both species.
