The results given in Table IX show that on an average the first 

 eggs were laid 2.7 days after the time of emergence of moths and that 

 oviposition extended on an average to 4.45 days. The average length 

 of time from the date of moth emergence to the last date of oviposi- 

 tion was 7.15 days; maximum, 14 days; minimum, 5 days. 



Length of life of moths. — A summary of observations on the length 

 of life of 367 male moths and 411 female moths is recorded in Table X. 

 A study of this table will show that the longevity of the males was 

 shorter than that for the females. On an average the males lived 

 4.44 days and females 6.24 days. The maximum length of life for 

 the males was 16 days, and for the females 15 days.
