ENTOMOLOGY 959 
Haematopota pellucida (Surcouf) 
Chrysozona pellucida Surcouf, 1909, Bull. Mus. Hist. Nat. Paris, XV, p. 457 (9; Leopoldville, 
Belgian Congo). 
The description of this species does not allow of its separation from H. 
denshamii Austen, of which I am inclined to regard it as a synonym. 
In addition to its occurrence in the Belgian Congo, H. pellucida has been re- 
corded from northern Angola (Gamble, 1914, Jl. Trop. Med. Hyg., XVII, p. 149). 
Neave (1912, Bull. Ent. Res., III, p. 315) includes it in the list of the blood- 
sucking insects of Nyasaland, but he does not mention it in his later paper on the 
Tabanidae of that territory and I rather doubt its occurrence there. 
Haematopota perturbans Edwards 
Haematopota perturbans Edwards, 1916, Bull. Ent. Res., VII, p. 158, fig. 10, Pl. Il, fig. 2 ( 9; 
Zambi, Belgian Congo). 
BELGIAN Coneo. — Tshela (Mayumbe), March 8, 1924 (A. Collart). Lemba 
(Mayumbe), December 1, 1915 (R. Mayné). Temvo (Mayumbe), March 1922 
(H. Schouteden). 
H. perturbans, of which I have seen one of the paratypes from Zambi, differs 
conspicuously from both H. duttona Newstead and H. pertinens Austen in the 
markings of the body: it is pale yellowish-brown without the olive-gray polli- 
nosity of the other two species; the dorsum of the thorax has five narrow, gray- 
ish-white, longitudinal stripes; all the abdominal tergites are narrowly margined 
with grayish-white, but are without discal blotches. 
This species is known only from the Lower Congo District of the Belgian 
Congo where it seems to be one of the more common tabanids. Edwards has 
also recorded it from the ‘‘ Upper Lubingo,’’ but I have been unable to locate a 
river of that name on any of the maps I have seen. 
Haematopota brunnipennis Ricardo 
Haematopota brunnipennis Ricardo, 1906, Ann. Mag. Nat. Hist., (7) XVIII, pp. 101 and 111, 
Pl. IV, fig. 11 ( 2; Salisbury, Southern Rhodesia). Newstead, Dutton and Todd, 1907, Ann. 
Trop. Med. Paras., I, p. 438. 
Newstead has recorded this species from the central Belgian Congo (Coquil- 
hatville, Nyangwe, and Kasongo), which is somewhat surprising in view of the 
fact that it is known otherwise only from Nyasaland, Southern Rhodesia, and 
Benguela. I have not seen it. 
According to the description, H. brunnipennis is closely allied to H. pertinens 
Austen and H. duttoni Newstead, but differs from both in having the stigma of 
the wing long, prominent, and followed by a semicircular, clear spot. 
Haematopota duttoni Newstead 
Haematopota duttont Newstead, 1907, Ann. Trop. Med. Paras., I, p. 41, Pl. IV, fig.3 ( 9; Nyangwe; 
Kasongo; Tschofa; Miambwe; all in the Belgian Congo). 
Chrysozona duttoni J. Bequaert, 1913, Rev. Zool. Afric., II, 3, p. 467, fig. 15 (¢).
