Average length of feeding period, 492 male and female larvae, 31.865 days; 226 male larvae, 30.960 days; 

 213 female larvae, 32.436 days. 



Maximum length of feeding period, 492 male and female larvae, 55 days; 226 male larvae, 55 days; 213 

 female larvae, 55 days. 



Minimum l<-ni:th of feeding period, 492 male and female larvae, 24 days; 226 male larvae, 24 days; 213 

 female larvae, 25 days. 



As was noted in 1913, the average feeding period of the transforming 

 larvse was shorter than that of the overwintering larvae. Likewise 

 the feeding period of the larvae reared hy the bagged-fruit method was 

 longer than the feeding period of larvse reared by any other method. 

 The fact that female larvae feed on an average for a longer time than 

 the male larvae was again proven in 1914. 



Larval life in the cocoon. — The average number of days spent by 

 the larvjc in constructing their cocoons was 6.166; maximum, 9 

 days; minimum, 3 days. (See Table XXXIII.)
