1880, the pupz of which consisted of six distinct varieties. 
This great diversity in the colouring of the chrysalis of this 
species must have been noticed by anyone who has reared it, 
although in all the standard works with which I am acquainted, ~ 
but one description is given. 
The larve of P. gonerilla are gregarious in their habits, but 
differ from the European species in resting and feeding on the 
under surfaces of the leaves, exposing as little of their bodies to 
view as possible. The pupa must be very closely concealed, for 
with the most careful searching, in places where I knew the larva 
had fed up, I was unable to find one. All my pupe were taken 
when in the caterpillar state, and kept till they changed. 
The perfect insect occupies an unusually short time in drying 
its wings, four hours being all that is mostly required, and on fine 
days it frequently was fluttering after having emerged but three 
hours. It is very powerful on the wing, flying against the most 
violent winds, and, indeed, if it were not it could never venture out 
at all, for in many parts of the islands it is always blowing hard. 
This insect is common from February to April in most 
situations, but the greatest numbers are to be found in the spring 
months. These hybernated specimens appear as early as August, 
and have not all disappeared before the end of December, or 
middle of January, when the earliest of the new ones are just 
appearing. In fact, it is not unfrequent at this time to take both 
hybernated and recent specimens together. This species is a great 
traveller, seldom settling, and mostly seen flying over the tops of the 
trees at a great rate. It shows a singular indifference to shadow, 
as it is constantly flying out of the sunlight into shady places in 
the bush, probably in search of the food-plant of the larve.

A eeonr VISIT Bio DOVER. 
By GEORGE COVERDALE. 
EHaruy in July I left London one afternoon for a few hours’ 
collecting on the S.H. coast, and arrived at my destination by 
six o'clock. ‘The weather was everything that could be desired, 
the very boisterous wind had given place to a dead calm, and the 
still hot evening sunshine blazed on the opposite coast of France,
