BLACK VEINED. 17
and Combe Wood, Surrey; Enborne Copse, near Newbury,
Berkshire, the residence of the famous "Jack of Newbury;"
Chelsea, Middlesex; Muswell Hill and Heme Bay, Kent; and
Glanville's Wootton, near Sherborne, Dorsetshire, are also given
as localities for it; but I believe it is no longer found in the
last-named situation.
The caterpillar feeds on the whitethorn, ( Cratcegus oxyacanthaj
the cherry pear, the Prunus spinosa, and other fruit trees.
This Butterfly varies in size from about two inches and a
quarter to nearly three inches: all the four wings are of a
dull milk-white colour, elegantly, at least in the eye of the
entomologist, streaked oyer with the black veins from whence the
insect derives its name; they shew through, the wings being
semitransparent, so that the under side resembles the upper
in its markings and general appearance.
In the female the veins of the fore wings are generally of a
brownish hue; and in one specimen that I have, the outer edge
is bordered with a very deeply indented line of blackish brown,
the indentations running up the veins to a point, but all united
together at the outside.
The caterpillar is at first black, but becomes afterwards
thickly covered with whitish hairs, and on the sides and un­
derneath is of a dark grey colour, with two longitudinal stripes
of red or yellow.
The chrysalis is greenish white, with two streaks of yellow
on the sides, a number of black dots, and a few black streaks.
