Moths of the first brood, 1919. — Of the 33 female moths of the first 

 brood segregated in pairs in jelly-glass cages in 1919, 8 of them failed 

 to deposit eggs as shown in Table 59. However, the remaining 25 

 laid 988 eggs, or an average of 29.94 eggs for the 33 females. The 

 average number of eggs per female in Table 10 is 23.39. The average 

 length of life of the 33 females in the individual cages was 15.24 

 days, which is 2.15 days longer than the average found in Table 11. 

 Table 59 also shows the maximum number of eggs per female to be 

 173, which is the largest number accurately recorded in these studies.
