IS DEIOPEIA PULCHELLA PERMANENTLY ESTABLISHED 
IN BRITAIN? 
By ReainaLp BK. Sanwey. 
Havine been so fortunate as to take a fine specimen of the 
beautiful and rare Deiopeia pulchella on the 1st June this year in 
a meadow about 3} miles inland from Folkestone, in the presence 
of Messrs. F. L. Whitmore and W. Austen, I was about to 
record my capture in the ‘Entomologist,’ when my attention 
was drawn to a note by Mr. R. South (Entom. 157). He 
answers a query of Mr. J. M. Adye’s with reference to the 
hybernation of Deiopeia pulchella, and adds that the species is 
probably not permanently established in Britain. I have never 
faced this theory before, and having so recently captured a 
specimen I am naturally anxious to have good grounds for 
retaining my old belief, that D. pulchella, although rare, has a 
real claim to a permanent place in our British list. To establish 
this claim is, unfortunately, out of my power, but to find some 
foundation for it is my present purpose. 
In the first place, I know of no rarity amongst our Lepi- 
doptera—perhaps excepting Vanessa antiopa—whose appear- 
ances, though erratic, have been so continuous throughout a 
period of many years. The back volumes of the ‘Entomologist’ 
prove this sufficiently, and I am personally aware of some 
specimens taken which have never been recorded ; and doubtless 
there are many other instances. In some years the number 
recorded of specimens captured is quite considerable ; at other 
times the record sinks to two, or only one, but that it is fairly 
continuous will, I hope, be admitted.
