taken at St. Margaret’s Bay. A specimen of M. atropos was sent to 
Mr. Barrows alive on June 19th, but only one ovum was obtained. 
Although this was probably an early immigrant there has been 
nothing to indicate that a considerable number arrived about that time 
as the autumnal records of the larvie are only moderately numerous. 
Vanessa antiapa has been seen in Essex, Kent, and the Isle of Wight, 
and the records of Colias hyale have been quite numerous; the localities 
extending from Norwich to Porthcawl in South Wales. As usual, the 
South-Eastern counties have been chiefly favoured, but the species 
does not seem to have been anything like so abundant as it was in 
1900. Colias edusa has also put in an appearance in Kent, Essex, and 
Cornwall, but in considerably fewer numbers than its generally rarer 
congener C. Injale. Deilephila livornica has been recorded from Sussex 
and Cornwall, and one or two specimens of what looked like a second 
brood have occurred during August in Hampshire and Surrey. This 
species is generally taken in June or early July. Sphinx convolvuli 
also has been tolerably abundant in the South-Eastern counties. 
Apparently, there have been no very striking movements in what are 
looked upon as our migrating species, including V. cardui and 
possibly V. atalanta. I saw one V. cardui in Cornwall on July 10th, 
which had all the appearance of having been on the wing a long time 
and was probably an immigrant. On July 9th I saw in the same 
place a specimen of V. atlanta which was in perfect condition and 
showed no signs of having travelled. 
A very interesting discussion has been going on in the journals as 
to whether the habits of V. atalanta are identical with those of V. cardui, 
so that each year we have to look to foreign arrivals, to keep up 
our stock of atalanta. Personally I have been so accustomed to look 
upon atalanta as indigenous, that the suggestion to the contrary came 
upon me as quite a surprise, and after reading evidence, for and 
against, I am still inclined to think that atalanta does get through our 
winter in a wild state, in one stage or another. As far as my 
observations are concerned I have never seen atalanta appear suddenly 
in anything like large numbers in a worn condition, as is so frequently 
the case with cardui. In fact whenever there has been a year when 
atalanta was a little more abundant than usual, they have always 
appeared at first in good condition, and it is not a species that varies 
in point of numbers to any very striking extent. With cardui the 
difference in the abundance of the insect is most marked, as in some 
years it appears to be entirely absent, and another year it may be in 
profusion, and I think I am right in saying that in all years of great 
abundance the arrival of worn specimens has been noticed some month 
or so before any really fresh specimens have been seen. Although 
there may be no absolute proof of atalanta having been found during 
hibernation, it is hardly sufficient reason for saying that it never 
hibernates with us, as we all know how few hibernating insects are 
found during their period of sleep, and we must still allow the 
possibility of the larvae or pupae surviving our winter, as both larvae 
and pupae have been found very late in the autumn. 
There appears to have been this year an effort on the part of 
Papilio machaon to find new pastures. It has been noticed in Hert- 
xxi.
