While, therefore, it seems probable that specimens from 
time to time find their way to Britain, as well as to some 
countries on the Continent, which are ill-adapted for its 
permanent establishment, yet there seems good reason to think 
that the annually recurring notices of its capture in the southern 
counties of England, as cited by Mr. Salwey, point to its 
permanent establishment there, although the delicacy of its 
constitution prevents its reproduction in any considerable 
numbers, except where more genial climatic conditions exist. 
A careful investigation of its life-history, combined with a 
comparison between the climates of Algiers, Corsica, or the 
southern portion of Provence and that of Britain, would probably 
throw much light apon this obscure question; and it may be 
allowable to suggest that while the summer of the South of 
England seems warm enough for the requirements of many 
exotic insects, both our spring and autumn are widely dissimilar 
from those of countries which border the Mediterranean; and 
this may afford the explanation desired. 
Mr. Harcourt Bath notices (Entom. 174) the profusion in 
which Pieris brassice has occurred in England during the past 
two seasons. Here, in Ireland, I observed it to be somewhat 
more numerous than usual, and this summer this is much more 
the case. The cause, perhaps, is the same as that I have 
indicated in the above remarks; and, as usual, we seem to lag 
behind England in good fortune.

Ca@:NONYMPHA TYPHON NEAR Barmoutu.— During the past 
week we have taken C. typhon (davus) in some abundance on a 
piece of peat moss a few miles from here, and as this insect is 
usually found at rather high elevations, it may be interesting to 
note its occurrence at this station, which is considerably less 
than 50 feet above sea-level. All the specimens taken have the 
grey and shaggy appearance of the hind wings described by 
Newman as characteristic of the typical C. typhon, as distinguished 
from the var. rothliebt. The latter we have not noticed here.—
