interfere with the health of the animals, but a great deal of inflamma- 

 tory changes occur in the nasopharynx, especially if the larvae are 

 abundant. It should be easy to devise some mechanical contrivance 

 to prevent larviposition. Oestrus ovis produces the condition in sheep 

 known as staggers. The author knows of no means of controlling 

 this pest.

The various stages of Chrysomyia bezziana, Vill., are described. This 

 is the common species causing myiasis of man and animals in India. 

 The eggs are laid either directly on the diseased tissue or in its 

 immediate vicinity, such as soiled dressings, etc. The larvae collected 

 hatched in about 28 hours. There can be very httle doubt that this 

 fly never oviposits in the bodies of dead animals. Attempts to raise 

 first and second stage larvae on decomposing matter failed, and only 

 a few were raised on recently killed rabbits. Several cases of attack 

 by this fly in man and animals are described, [cf R.A.E. B, ix, 53.]

Passeromyia heterochaeta has been taken from nests of house sparrows 

 in India. As soon as a bird dies, it is attacked by the larvae, which 

 suck out the body fluids and even penetrate the abdomen. 



Phormia azurea is recorded from birds' nests, especially those of 

 thrushes and chaffinches, in Great Britain.

Musca divaricata and M. promisca were used for the experiments 

 described. Both species were found to oviposit throughout adult life, 

 and the flies usually died within a week after laving the last batch of 

 eggs. The first eggs are laid from 9 to 18 days after emergence. The 

 interval between the batches was generally short, but in some cases 

 lasted from 6 to 10 days. M. divaricata never laid less than 50 eggs, 

 while M. promisca never laid more. The latter species generally 

 chose fresh human faeces for oviposition, though it would also lay 

 eggs on fresh goat dung if the former was not available, but M. divari- 

 cata invariably oviposited on goat dung. The average life of the 

 individual was 16 days, the total life-cycle from e^^ to e^g occupying 

 about a month.
