1 6 Second Report on Economic Zoology. 



through woods, and in the neighbourhood of water. They are most 

 vicious of all the Tabanidm, 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 wouuds 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 Tabanidx., 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 larva^ are of a lot passed per rectum of a child ; two cases 

 in Liverpool." 



These larvse belong to the genera Musca and Homalomyia. The 

 first-named is just like Mvsca domcstica, but there are eight round 

 knobs to the lateral processes, not seven, as in domcstica. 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. canicularis, L. A paper on these two interesting cases of 

 Myiasis is being prepared by Dr. Stephens.
