1026 THE BUTTERFLIES OF NEW ENGLAND. 



should be sought. How it is that when so brief a time is required for 

 the complete cycle from egg laying, broods do not follow each other with 

 greater rapiditv ? How soon after birth does the female lay eggs ? How 

 large a proportion of August chrysalids give birth to the imago in the 

 same year, and how many pass over the winter? Does the imago ever 

 hibernate? and if so in what condition are her ovaries during the winter 

 season ? Does the egg ever hibernate, as would seem quite possible from 

 its location ? Do any parasites attack the egg or caterpillar successfully ? 

 Do ants ever destroy the egg or the caterpillar ? What is the actual time 

 required for moulting, including the rest anterior to it? Does the cater- 

 pillar ever moult more than three times ? The flight and postures of the 

 butterfly are unknown ; and it would be well to determine whether the 

 butterfly, whose tongue is short, ever seeks the juices of the plant-lice for 

 its own delectation.
