DEIOPEIA PULCHELLA. 205 
If on entering the wood we follow the path westward, we 
come to the high-road again, and, bearing to the left hand, we 
shall find some nice collecting-ground, with very mixed under- 
growth, shrubs, and trees; birch being in plenty. I have seen 
this place and all the Chart south of this road, east of the mill on 
the top, well alive with insects in early spring, Brephos especially 
abounding. In continuing our walk we may either take the road 
to the east of the mili on the top of the Chart and so back to 
Westerham, or, if London bound, across Lingfield Common to 
Oxted station, and so home. 
The Westerham district is good at any period of the year, 
when collecting is to be done, from sallows in the spring to 
heather bloom in the autumn. The flora and foliage are so varied 
that mothing will repay at any time during the season; while 
many moths should be taken at sugar, both in species and 
specimens. Much of the ground is open to the public, and the 
locality is by no means over-run by excursionists. 
I have given but a very slight sketch of some of the many 
walks to be taken in the neighbourhood, and only sufficient is 
intended to induce naturalists to take an interest in the locality. 
I leave to the explorers the pleasure of finding out for themselves 
what occurs in the district, and the sudden surprises in store for 
them will, I am sure, make many an entomologist rejoice that he 
has visited Westerham.

DEIOPEIA PULCHELLA.

Mr. Satwey’s paper (Entom. 170), discussing the claim of 
Deiopeia pulchella to be considered a permanent British species 
or merely an occasional visitor, touches upon a subject which is 
gradually attracting increased attention. ‘he migrant habits of 
many of our Heterocera and some of our Rhopalocera are becoming 
more widely noted, although the causes are still somewhat obscure. 
The increased abundance of many of the Sphingide in Britain, 
during summers of abnormal heat, appears not due solely to the 
suitability of such seasons for the reproduction and multiplication 
of such of them as require a greater warmth during some stage
