Moths of the first brood, 1916. — The study of the number of eggs 

 deposited by moths of the first brood was continued in 1916 on a more 

 extensive scale than during the preceding year. The methods em- 

 ployed, however, were identical in all respects. The data herewith 

 given were obtained by recording daily the number of eggs laid by 

 201 female moths, beginning with moths that emerged July 11 and 

 ending with moths that issued August 22. As will be seen in Table 

 LXXVI, these 201 individuals deposited a total of 17,225 eggs, or an 

 average of 85.70 eggs per female.
