emergence and oviposition, the length of the life cycle would be: 
Minimum, 39; maximum, 73; average, 49 days. These indoor records 
show an average life cycle 5 days shorter than the outdoor records 
(on bagged fruit) of 1908. Table XVIII gives a record of the 1907 
rearings.

THE THIRD GENERATION. 
THIRD-BROOD EGGS. 
In the cages third-brood eggs were first secured August 5. The 
calculated time for their first appearance in the field is 10 days 
earlier. The last eggs observed were laid in a cage October 16 by 
moths emerging up to October 1. 
All second-brood and third-brood eggs laid before August 28 
hatched in 5 days, the usual summer incubation period. During 
September the egg stage was gradually lengthened toward the maxi- 
mum period shown in early spring eggs. The eggs from which the 
third-brood larvze were reared incubated as shown in Table XIX.
