curled leaf, or elsewhere, and lines the place chosen with silk. At 

 this time the larva loses much of its brown color, becomes a dirty 

 grayish white, and also becomes somewhat shortened. In this con- 

 dition it may continue several days or even a week before pupation 

 finally takes place. 



In both 1920 and 1921, a number of larvae were collected in the 

 field when nearly full grown, and the exact dates of pupation and 

 emergence were noted, the resulting data being presented in Table 2.

Table 3 gives data regarding the duration of the period of pupa- 

 tion under Connecticut conditions in 1920 and 1921, summarizing 

 Table 2. The period varies from 12 to 21 days, with an average of 

 15 to 16 days.
