The foregoing data regarding A. stygia constitute the first 
published detailed information regarding the life periods of this 
species. 
The series of observations relating to A. augur show an 
extension of the limits already published regarding the species 
by Johnston and Tiegs. The larval period ascertained is 
identical, but the prepupa was found to range from two to 
13 days, the prpa from 10 to 14 days, and the total period 
{deposition to emergence) 17 to 32. The minimum total period 
previously found was 19 days.

The information given above constitutes the first published 
data regarding the life-cycle of this fly. A large female speci- 
men, the identity of which was not known at the time, deposited 
fifteen larvee in a tube within which it was confined, and into 
this tube was placed a piece of meat that was considered 
scarcely enough to allow the maggots to come to maturity, so 
that their development could be closely watched. On the fourth 
day all had reached their prepupal stage, but only five wandered 
away. The next day only three further specimens had left,
