The second moult began on 9th April, and the last one of 10 larvae 

 passed same 21st April, a difference of 12 days. 



The third moult began 21st April, and the last of 8 larvse passed same 

 7th May, a difference of 15 days. 



The fourth moult began 3rd May, and the last of 9 larvae passed same 

 6th June, a difference of 34 days. 



The first chrysalis formed 20th May, and the last larva was mature 

 loth June, and would have pupated about 15th, had I not put it in alco- 

 hol. The difference would have been about 26 days in pupating. 



The first imago out of chrysalis was on 2nd June, the pupa period 

 being from 11 to 12 days. 



So that, supposing larvae to behave in natural condition as these in 

 confinement, fresh butterflies from same brood would be coming out 

 daily for several weeks. And so undoubtedly they do, as is the case with 

 Alope.
