In 1907 the period in the fruit was determined for 33 second-brood 

 larvae 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 larvae 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 larvae would also apply 

 here. Individual records are shown in Table XIV. 



SECOND-BROOD PUP^E. 



Pupae appeared out of doors as late as September 14. These, how- 

 ever, were from larvae that left the fruit September 1 or before, and 

 only a few larvae leaving the fruit later than August 20 transformed. 

 In the laboratory pupae appeared well into November. In 1907 larvae 

 appearing under bands later than August 26 generally failed to pupate, 

 so that the last pupae in both seasons appeared early in September. 



Of 78 second-brood pupae, from larvae 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.
