LARGE WHITE.
a singularly small specimen in my own collection, figured
in the plate, measures under two inches across. The upper
surface of all the wings is white, the fore ones having a broad
black patch following the angles of the outside corner, and
indented on its lower inner edge. There is a pale blackish
grey margin at the front of the wings, extending nearly to the
patch at the corner; and the whole front edge has a line of
black along it. Occasionally, but very rarely, the males have
a black spot on the fore wings: the hind wings have a black
spot on the middle of their front edge. Underneath, there are
two black spots on the fore wings, which however are inde­
pendent of any generally apparent corresponding markings on
the upper side. The hind wings are dull yellow, minutely
dotted all over with black specks. There is only a faint trace
of the black mark on the middle of the front edge.
The female has the outside patch larger than in the male,
with its inner edge more or less deeply indented. There are
also two large irregular round black spots on the middle of the
fore wings, and immediately beneath them a streak of the same
running along the lower edge of the wing, and attenuating
towards the body. The hind wings have a triangular-shaped
spot on their front side in a line with the spots on the fore
wings. Underneath, the fore wings shew the black spots plainly
through, and the black patch very faintly. The hind wings are
of a dull greenish colour, dotted all over with very minute black
spots, and shewing the black triangular patch rather obscurely
through.
The eggs are deposited in clusters.
The caterpillar is greenish yellow, the segments being almost
covered with black tubercles of different sizes, from each side
of which arise white hairs, three of the larger ones forming a
triangle. The head, fore legs, and hind segment are also black.
There is a line of green down each side, and one along the
back.
The chrysalis is pale green, spotted with black, and with three
yellow lines.
Varieties occur both in size and markings. A very remarkable
