Liserta. — Kolobanu, several adult flies, October 19, 1926. Reppo’s Town, 
one female and several larvae in the native huts, August 31, 1926. Gbanga, 
several male and female flies and numerous larvae in native huts, September 
1926. The native name of the maggot among the Kpwesi is “‘mboro.”’ 
Beuc1an Conco. — Nya Ngezi, adult flies, February 3, 1927. Luvungi, 
adult flies, January 30, 1927. Lulenga, 1,800 m., one adult fly in a house, March 
6, 1927. 
The larva of A. luteola is the celebrated blood-sucking ‘‘ Congo floor maggot,”’ 
which lives in the huts of the African natives. During the daytime it hides in 
the dust of the adobe floor and walls. At night it comes out in search of sleep- 
ing human beings. The bite is apparently painless, and, to judge from the many 
engorged specimens found in the huts, the parasite has no trouble in completing 
its meal. So far as known, this insect transmits no disease. Its distribution 
covers practically the entire Ethiopian Region from Senegal, the Anglo-Egyptian 
Sudan and Eritrea to Natal and Southwest Africa. In the mountains of tropical 
Africa, it reaches an altitude of 2,300 m. 
A. luteola is a specific parasite of man, which has not yet been found in nature 
associated with any other host, although Roubaud has raised it on other mam- 
mals, notably on the domestic pig. Moreover, there are in Africa several other 
closely allied species of muscoid flies, whose maggots suck the blood of wild 
animals: Choeromyia boueti Roubaud, C. choerophaga Roubaud, C. bequaerti 
Roubaud and Pachychoeromyia praegrandis (Austen).1 The larvae of these 
species hide in the dirt at the bottom of the burrows of aardvark (Orycteropus 
senegalensis Lesson and O. afer Pallas) and warthog (Phacochoerus africanus 
Gmelin). 
Cordylobia anthropophaga (Hm. Blanchard) 
Ochromyia anthropophaga Km. Blanchard, 1872, C. R. Ac. Sci. Paris, LXXV, p. 1134 (without 
description; name based upon an adult fly obtained from a larva attacking either man or dog 
1 Choeromyia Roubaud (1911, C. R. Ac. Sei. Paris, CLIII, p. 553) and Pachychoeromyia Villeneuve 
(1920, Bull. Soe. Ent. France, p. 225) are hardly more than subgenera of Auchmeromyia Brauer and y. 
Bergenstamm (1891).
