upon the hypopleura. 
Cordylobia anthropophaga is very widely distributed in 
Africa, its range extending from Senegal to Natal, and 
coinciding with that of Awchmeromyia luteola, Fabr., the 
“ Floor-Maggot Fly,” to which in the perfect stage it presents 
a remarkable resemblance in coloration and general appearance. 
This similarity has already been productive of confusion, 
although the life-histories of the two species are widely 
different, since the maggot of A. luteola, which by day lies 
buried in the cracks in the earthen floors of native huts, has 
the extraordinary habit of coming out by night to fasten upon 
and suck the blood of the sleeping inmates. 
The earliest published account of the life-history of Cordy- 
lobia anthropophaga is that by two surgeons in the French 
navy, MM. Coquerel and Mondiére, who in 1862 described * 
cases in which soldiers had been attacked by the larve in 
Senegal. In one instance a man had two larve in his fore- 
arm, while another individual had eight in the back of his 
shoulder. The French authors gave a description of the 
maggot, but failed to breed out the fly, which they were 
inclined to regard as in all probability belonging to the 
(Hstride, and to a new genus allied to Hypoderma, in which 
are included the well-known “ Warble-Flies ” of cattle. 
In 1872 another French naval surgeon, M. Bérenger- 
Féraud, in a note presented to the French Académie des Sciences 
by Baron Larrey,t made further reference to the larva of this 
fly in Senegal, where, from the name of the district in which 
it was most common, it was said to be known as the “* Ver de 
Cayor,” or “Cayor Worm.” In this paper it is stated that 
seventy-eight of these larve had been removed from all parts 
of the body of a spaniel, and the author mentions that he had 
himself counted more than three hundred larve in a puppy of 
the same breed ; it is scarcely surprising to learn that the
