Daily Record of 14 Females op the Hibernated Generation.' — Concluded. 



' Dates accompanied by no record were omitted from ttie original table. 



This record indicates that both the length of life and number of eggs 

 deposited varies considerably, but as a matter of fact, I believe that 

 those females that died before depositing at least six egg masses would 

 have lived longer under more favorable conditions. At the same time 

 Nos. 2, 4, 8 and 10, females that .deposited eggs quite irregularly to- 

 ward the last, may very probably have died a natural death. Hence 

 it would seem to me that by taking the average of the number of eggs 

 obtained from females depositing at least six egg masses, we would 

 have a fair average number that might be laid under normal or nat- 

 ural conditions. Granting this to be a correct supposition, we have 

 99 1-9 for the average number of eggs laid by each hibernating female.
