264 EXPERIMENT STATION RECORD. [Vol. 40 



Oviposition began during the second night after emergence from the ground. 

 The average number of eggs deposited by 2,500 females was 82.7. It was found 

 that there were 11.7 eggs per milligram ; dissections showed the presence of as 

 many as 400 eggs. The percentage of sterility of eggs varied from 10.8 per cent 

 for those deposited the first night in captivity up to 46.7 per cent for those 

 deposited on the fourth night, and thereafter 82.8 per cent, with a general 

 average of 19.15 per cent sterility. The incubation period of the egg mass 

 varied from 23 to 32, with an average of 26 days. 



The average longevity of females after capture was about 9 days. It waa 

 found that in case a moth is able to drag herself through the sticky band and 

 go on up the tree she is not likely to deposit more than 16 per cent as many 

 eggs as she would otherwise have done under normal conditions. It was also 

 found by isolating individuals that eggs are not all deposited at one time, but 

 may be laid in at least four different masses. The details are given in tabular 

 form.
