Larval life in the cocoon. — Individual records were kept upon the 

 time of cocooning, time of pupation, and emergence of the moths on 

 141 larvge. (See Tables XVIII and XIX.) Under this heading 

 would be placed the post-larval stage or the period between the first 

 spiroiing of the cocoon and the time of pupation. The variations 

 in the length of larval life in the cocoon are given in Table XVII.
