puppy died. M. Bérenger-Féraud, who succeeded in breeding 
out specimens of the perfect insect, states that they were 
‘very active, and much resembled house-flies.” To this com- 
munication a note by M. Emile Blanchard, to whom the paper 
had previously been submitted, is added. From the details 
supplied to him, M. Blanchard thought that the “Cayor 
Worm Fly” belonged to the genus Ochromyia, Macq., and to 
a new species, for which he suggested the name Ochromyia 
anthropophaga. Since, however, no description of the fly what- 
ever was given, Ochromyia anthropophaga, Emile Blanchard, 
is a mere nomen nudum, and consequently invalid. 
Under the name of the “Tumba” or “Tumbu” Fly, the 
insect, or rather its larva, is well known in Freetown, Sierra 
Leone, where residents often suffer from the painful boil 
produced by the maggot. Dogs and pet monkeys are fre- 
quently afflicted in the same way, and during a visit paid by 
the speaker to Sierra Leone in 1899 he fortunately succeeded 
in obtaining eleven larve and pup from a small Mangabey 
monkey (Cercopithecus sp.). From the pup that were allowed 
to mature there emerged five flies, which proved of much 
interest to local medical men, since complete ignorance as to 
what the ‘Tumba Fly ” really was had previously prevailed 
in Freetown. Some people were even inclined to consider it 
to be a ‘‘ Mangrove Fly” (7. e. Horse-Fly,—Family Tabanidz), 
a belief that, as was subsequently found, was also entertained 
at Calabar, in Southern Nigeria. 
On Sept. 30th, 1891, Mr. L. Péringuey, F.E.8., of the 
South African Museum, Cape Town, exhibited at a meeting 
of the South African Philosophical Society a fly, “ bred from 
larve, nine in number, extracted from the arm of a child 
in Natal.” Ina note read at the same time, Mr. Péringuey 
said with reference to the species,—which, from the extensive 
series of specimens from Natal and elsewhere in the British 
Museum (Natural History), there can be no doubt was 
identical with the “Tumba Fly” of Sierra Leone and the 
“Cayor Worm Fly” of Senegal—that it was “ perhaps allied 
to Bengalia depressuw (Walk.).” * In some further notes on
