ENTOMOLOGY 985 
I have recorded this species from Elisabethville and Sankisia, in the Katanga 
District of the Belgian Congo; but the specimens in question are not now 
before me. 
S. taeniata appears to be an East-and-South African species, known at present 
from Eritrea, Abyssinia, Kenya Colony, Tanganyika Territory, the Katanga, 
Nyasaland, and Natal. 
Stomoxys rhodainica Roubaud 
Stomoxys rhodainica Roubaud, 1925, Bull. Soc. Path. Exot., Paris, XVIII, p. 468, fig. 2 (9°; 
Kibati, north of Lake Kivu, Belgian Congo). 
Brute1an Conco. — Mai Ivwi (north of Ruchuru), alt. about 1,100 m., 
March 3, 1927, three males biting buffalo (R. P. Strong). 
Stomoxys ochrosoma Speiser 
Stomoxys ochrosoma Speiser, 1910, in Sjéstedt, ‘Wiss. Ergebn. Schwed. Zool. Exp. Kilimandjaro,’ 
II, 10, 5, p. 162 ( 2; Kibonoto, Kilimanjaro, Tanganyika Territory). Roubaud, 1925, Bull. 
Soc. Path. Exot., Paris, XVIII, p. 467 (¢). 
BELGIAN Coneo. — Mai Ivwi (north of Ruchuru), alt. 1,200 m., March 3, 
1927, one male biting buffalo (R. P. Strong). 
The first females of this species were supposedly taken by Sjostedt hovering 
over the columns of driver-ants. Dr. J. Rodhain found a female biting a mule 
in the hills of Luvungi (south of Lake Kivu; alt. 1,500 m.). 
Male (undescribed). — Similar in coloration to the female, but the dorsum of the thorax with 
a broad median black stripe, slightly widened anteriorly and posteriorly and narrowly interrupted 
at the transverse suture. Wings uniformly ash-gray with a yellowish tinge. Frons moderately 
wide and almost parallel-sided. Fore basitarsus with a dense fringe of peculiar, curled, hook-like 
bristles; the second and following segments of fore tarsi without curved hairs. Length, 6.5 mm.; 
of wing, 7.5 mm.; of proboscis, 4 mm. 
Stygeromyia Austen 
Stygeromyia Austen, 1907, Ann. Mag. Nat. Hist., (7) XIX, p. 445. Monotypic for Stygeromyia 
maculosa Austen, 1907. 
So far as known, this genus occurs only in Africa and Arabia, whence the 
following five species have been described: 
1. S. maculosa Austen, 1907, Ann. Mag. Nat. Hist., (7) XIX, p. 447 (7; Little Aden, Southern 
Arabia). 
2. S. rufipalpis (Becker) = Lyperosia rufipalpis Becker, 1910, Denkschr. Ak. Wiss. Wien, 
Math.-Naturw. K1., LXXI, p. 148 (7; Ras Fartak, Socotra). According to Bezzi, this is possibly 
the same as S. maculosa Austen. 
3. S. sanguinaria Austen. See below. 
4, S. thirouxt (Roubaud) = Lyperosia thirouxt Roubaud, 1906, C. R. Soc. Biol., Paris, LX, 
p. 896, fig. 1 (9 7; St. Louis, Senegal). At Dakar, crithidial flagellates have been found in one 
specimen of S. thirou«i that had fed on horses. It is, however, unknown whether they were specific 
parasites of the fly or represented stages in the evolution of a trypanosome of vertebrates (M. 
Léger, 1922, C. R. Soc. Biol., Paris, LX X XVII, pp. 184-136). 
5. S. woosnami Austen, 1912, Bull. Ent. Res., III, p. 97 (#; plateau above Naivasha, Kenya 
Colony).
