1 6 Second Report on Economic Zoology . 
through woods, and in the neighbourhood of water. They are most 
vicious of all the Tccbanidee, attacking both man and animals, 
especially horses. Their bite is very painful, and they not only 
draw away quite a lot of blood, but leave behind a wound from 
which blood continues to ooze. Many nasty wounds are caused by 
these flies. They undoubtedly carry poisonous germs, which pass 
into the system when the proboscis is inserted. To bathers in most 
small rivers in the south of England they are most annoying. The 
females only bite, the males live upon the juices of flowers. Their 
flight is silent, and like other species of Tabanidne , they occur in 
greatest numbers in hot and sultry weather, delighting in the 
brightest sunshine. 
Dipterous Larvae in Children. 
Dr. J. K. W. Stephens forwarded in November two kinds of 
dipterous maggots with the following note : — 
“ The larvae are of a lot passed per rectum of a child ; two cases 
in Liverpool.” 
These larvae belong to the genera Musca and Homalomyia. The 
first-named is just like Musca domestica, but there are eight round 
knobs to the lateral processes, not seven, as in domestica. Probably 
it is M. corvina. This is the first record of the larva of Musca living- 
in human beings. 
The Homalomyia were hatched out by Dr. Stephens and proved 
to be H canimlaris , L. A paper on these two interesting cases of 
Myiasis is being prepared by Dr. Stephens.
