ciata Fab. Only one, a normal female, emerged May 28 
and lived 8 days. The very evening of its first day it 
deposited infertile eggs, During its lifetime it laid 186 
eggs and retained 10 after its death, making a total num- 
ber carried of 196 eggs. One of the other chrysalides, 
when opened some time after all expectation of 
emergence was gone, was found to contain an adult moth, 
dead, which for some reason had not been able to effect 
the proper emergence. It was a female and it must 
have lived for some time, since 12 eggs had been de- 
posited in this prison house.
