In 1907 the period in the fruit was determined for 33 second-brood 
larvee which hatched July 10-15. All were reared in picked fruit 
kept in the laboratory: The shortest time was 15 days, longest 22, 
average 18.1 days. The 1907 rearings are tabulated in Table XIII.

Larval life in cocoon. —Of 75 larve maturing from July 12 to Sep- 
tember 1, the time between leaving the fruit and pupation (in vials 
out of doors) varied from 3 to 21 days, with an average of 11.86 days. 
The remarks on this stage of the first-brood larve would also apply 
here. Individual records are shown in Table XIV. 
SECOND-BROOD PUP. 
Pupz appeared out of doors as late as September 14. These, how- 
ever, were from larve that left the fruit September 1 or before, and 
only a few larve leaving the fruit later than August 20 transformed. 
In the laboratory pupz appeared well into November. In 1907 larvee 
appearing under bands later than August 26 generally failed to pupate, 
so that the last pupe in both seasons appeared early in September. 
Of 78 second-brood pupex, from larve maturing after July 12 and 
until September 1, the longest pupal stage was 17 days, shortest 8, 
average 10.5 days. The longest total period in cocoon was 38 days, 
shortest 12, average 20.4 days. This material was kept in small 
vials, and the period between leaving the fruit and pupation was 
probably abnormally long, on account of the difficulty in spinning a 
suitable cocoon. The individual records are given in Table XIV.
