the same species, published in the Minutes of Proceedings of 
the South African Philosophical Society at the meeting held 
on Sept. 30th, 1896,* Mr. Péringuey refers to his former 
hypothesis, which he describes as a suggestion that the fly 
*“‘ would, perhaps, prove to belong to the genus Bengalia.”’ He 
adds :—“ I was quite right in my surmise, the genus Bengalia 
and Ochromyia being partly synonymous.” From this it is 
evident that Péringuey was thinking of the undescribed species 
for which the name Ochromyia anthropophaga had been 
suggested by Emile Blanchard ; and indeed on the following 
page (p. xxiv) Mr. Péringuey states that “the species bred in 
Natal might prove to be identical” with the ‘‘ Cayor Worm.” 
Mr. Péringuey’s remarks, although containing nothing in the 
shape of a statement that the parasitic fly of Natal is actually 
Bengalia depressa, Walk., appear to have been quite sufficiently 
definite for certain writers in South Africa as well as in this 
country, with the result that the species with which we are 
concerned is now widely known as “The Natal Maggot Fly 
(Bengalia depressa, Walker).” + The true Bengalia depressa, 
Walk. (the type of which is in the British Museum), is, however, 
as shown by the specimens exhibited, albeit an allied, nevertheless 
a very different insect. Its life-history is as yet entirely unknown, 
and there is not a particle of evidence to prove that its larva is a@ 
subcutaneous parasite.

confounded, Auchmeromyia luteola, Fabr., the African “ Floor-
