Oil the Breeding of M. domestica during the 
Winter Months. 
In the account that I gave of the breeding habits of M. 
domestica in the second part of this monograph, it was 
stated (p. 503) that the experiments and observations pointed 
to tlie fact that, in the presence of suitable larval food, such 
as excrernental matter or decaying and fermenting food 
materials in a moist and warm condition, the female flies 
would lay their eggs and the larvie would develop if the 
temperature of the air was sufficiently high for the prolonged 
activity of the flies. Flies are sometimes found under these 
conditions in warm restaurants and kitchens, stables, and 
cowsheds, and under these conditions are able to breed during 
the winter mouths. I am pleased to find that my own observa- 
tions and those of Griffith (there referred to) as to the ability of 
M. domestica to breed during the winter months has been 
confirmed by Jepson^ during the past winter. 
Flies were caught in February (1909j in the bakehouse of
