BELGIAN Congo. — Kamaniola, six nearly adult larvae in the scrotum and 
one larva in the tail of a rat, Mastomys coucha ugandae (De Winton), January 31, 
1927; this rat was in a dying condition and the sores also showed a secondary 
infection with sarcophagine maggots. Luebo, two larvae in the third stage from 
the skin at the ventral side of a wild rat (H. Schouteden. — Congo Museum, 
Tervueren). 
Ucanpba. — Northern Districts, two larvae in the third stage (J. Watt. — 
London School Trop. Med.). 
NorTHERN Niceria. — Three almost full-grown larvae, probably from the 
region of Zungeru (W. B. Johnson. — London School Trop. Med.). 
This well-known agent of cutaneous myiasis in man and animals is distributed 
throughout tropical Africa in the more open bush and savanna country, from 
Senegal to Natal. It is, however, not found in the humid rain forest belt, where 
it is often replaced by a near relative, Stasista rodhaini (Gedoelst), discussed in 
the sequel. There is no record of C. anthropophaga from the Cape Province of 
South Africa, south of the Orange River. 
The most complete account of the early stages, habits, and distribution of 
C. anthropophaga has been published by E. Roubaud in 1914. Notwithstanding 
the specific name ‘‘anthropophaga,” this insect is only an accidental, though 
rather frequent, parasite of man. Cases where maggots from the human skin 
reach the adult stage and produce flies must be exceedingly rare, as the parasite 
is readily removed; so that the species would soon become extinct if man were 
its specific or chief host. The regular or normal hosts of this fly are very numer- 
ous in Africa, but certain wild rodents are probably its chief victims. 
During the several years of his medical practice at Monrovia, Dr. Bouet 
has never observed C. anthropophaga. The Harvard Expedition also has failed 
to obtain any evidence of its occurrence in Liberia. In view of the abundance

de ‘homme au Sénégal.’ C. R. Ac. Sci. Paris, LX XV, pp. 1133-1134 (with a note by Em. Blanchard, 
p. 1134). 
The earliest account of these parasites appears to be that of C. Coquerel and Mondiére, 1862, Ann. 
Soc. Ent. France, (4) II, pp. 95-103; and 1862, Gazette Hebdom. Méd. Chir., LX, pp. 100-101. They 
studied larvae from Senegal, but did not know the adult fly.
