imperfectly known that
the recorded habitats must be received with great doubt; it
is certainly abundant on the banks of the Thames, near
Gravesend, and also on the Irish coast, near Waterford."

The marks of sugaring remain on tree trunks for many years. I lately
saw the faint remains on about sixty trees in Set Thorns plantation,
in the Forest, which a friend and I painted on nearly forty years ago.
This friend was fortunate in capturing the black variety of the White
Admiral, in which the white markings are entirely absent on the upper
side; and, thirty years later, his son took another near Burley. The
son also caught a Camberwell Beauty on one of his sugared patches in
the day-time. I believe this to be the only recorded instance of the
occurrence of this rare and beautiful insect in the Forest.

The Hornet Clearwing (_Sesia Apiformis_) is a very interesting moth,
and it was common at Aldington; the larva feeds on the wood of the
black poplar. The colouring of the moth so resembles the hornet, that
at first sight it is easily mistaken for the latter. It is an
excellent example of "mimicry," whereby a harmless insect acquires the
distinctive appearance of a harmful one, and so secures immunity from
the attacks of its natural enemies.

The larva of the Death's Head was not uncommon at Aldington and Badsey
on potatoes; I had a standing offer of threepence each for any that
the village children could bring me. These large caterpillars require
very careful handling, and I fear the children were not gentle enough
with them, as I only had one perfect specimen moth from all the larvae
they brought.

One of my hop-pickers captured and presented me with a very fine
specimen of the Convolvulus Hawk-moth at Aldington; they were
generally comparatively common that year (1901) and a collector took
no less than seventeen in a few days in the public garden at
Bournemouth.

The Clouded Yellow butterfly, whose appearance is very capricious,
occurred one summer in Worcestershire in considerable numbers; it is
strong on the wing and could easily reach the Midlands in fine weather
from the south of England, where it is more often seen. Those I saw
were flying high over clover fields, apparently in a hurry to get
further north-west.

The Marbled White is a somewhat local butterfly; there was a spot
along the Terrace on Cleeve Hill, near North Littleton and Cleeve
Prior, where, at the proper time, this insect was
