Careful examination of the bands was made, beginning about 

 June 1, but no larvae were taken until June 17, only two days earlier 

 than in 1912, in spite of the fact that the first of the spring -brood 

 moths were probably 10 to 15 days earlier than in the former season. 

 From June 17 the collections increased until about August 1, when the 

 numbers of insects collected decreased slightly, the proportion of 

 those wintering increasing, and probably by August 7 to 10 most of 

 the larvse taken were of the second brood. The fact that the second 

 brood did not equal the first in numbers and were somewhat irregular 

 in their appearance under the bands is explained by the short fruit 

 crop of the year. 



Altogether 971 larvae were collected and reared. Of this number 

 24.10 per cent were killed by handling, cannibalism, etc., the loss 

 from this source being about the same as the 27.19 per cent that died 

 from similar causes in 1912; 33.57 per cent were transformed to first-
