5. A. Neave, having bred this species, concluded that 7. corax Loew was 
identical with 7’. leucaspis van der Wulp (renamed 7’. wanthomelas by Austen). 
Nothing, however, in Loew’s description supports Neave’s conclusion. 
Through the kindness of Dr. Vult Ziehen, I have recently had the privilege 
of examining Loew’s type, now in v. Roeder’s collection at the Zoological 
Institute of the University at Halle a. S. I shall report upon it more in detail 
elsewhere. Suffice it to say that 7. corax is not in the least related to T. 
xanthomelas Austen, but belongs in the group of 7’. ruficrus Palisot de Beauvois. 
T. xanthomelas seems to be very widely spread over the Ethiopian Region, 
from French Guinea to Nyasaland. The correct distribution, however, cannot 
be traced at present, since the species has been generally confused with 7’. pluto 
Walker. The two species may be separated as indicated in the key. 
Tabanus pluto Walker 
Tabanus pluto Walker, ‘1848, List Dipt. Brit. Mus.,’ I, p. 153 ( @; Sierra Leone). Austen, 1909, 
‘Tllustr. African Blood-Suck. Flies,’ p. 91 (in part; not the figure); 1912, Ann. Mag. Nat. 
Hist., (8) IX, p. 29. 
Liperia. — Mt. Coffee, one male (R. P. Currie). 
The true 7’. pluto is most probably restricted to Upper Guinea. The area 
which it occupies seems to correspond to J. P. Chapin’s Upper Guinean Forest 
and Savanna Districts of the West African Subregion (1923, American Natu- 
ralist, LVII, p. 121, fig. 11). It has often been recorded from the Belgian Congo, 
but I believe upon erroneous identifications. All the specimens which I have 
seen from that territory were 7’. xanthomelas Austen. I doubt greatly whether 
true 7’. pluto is found in the French and Belgian Congo, or in Portuguese West 
Africa. 
Tabanus fulvicapillus Carter 
Tabanus fulvicapillus Carter, 1912, Ann. Trop. Med. Paras., VI, p. 437, Pl. XXIII, figs. 2 and 7 
(9; Banana, Belgian Congo). 
This species is known only from the type locality. 
So far as one can judge from the descriptions, 7’. fulvicapillus presents 
many points of similarity with 7. rowbaudi Surcouf (1909, Bull. Mus. Hist. 
Nat. Paris, XV, p. 358, 9; 1909, “Et. Monogr. Taban. Afrique,’ pp. 149 
and 155, 9, fig. 21), known only from the type and two paratypes taken at 
Pangala (Boule N’ Tangou), north of Brazzaville, French Congo. 1. roubaudi 
is 11.5 to 12.5 mm. long and has pale spots covered with golden hair in the hind
