22 SMALL WHITE.<br />
The caterpillar feeds on the cabbage, (Brassica oleracea.J<br />
The expanse of the wings varies from one inch and three<br />
quarters, to nearly two inches and a half: a singularly small<br />
one, captured some years since, by my brother Frederick Philipse<br />
Morris, Esq., is figured in the plate. The colour of this insect<br />
is milk-white; the fore wings have a dusky or black mark,<br />
irregularly defined at the tip, extending along part of the mar<br />
gin; and there is a black spot near the middle of the wing, and<br />
a second indistinctly visible. The hind wings have a dull dusky<br />
black mark in a line with them, about the middle of the fore<br />
edge. Underneath, the mark at the tip shews through, of a pale<br />
yellowish colour, and there are two black spots near the centre;<br />
in fact the same as those, one of which only is apparently visible<br />
on the upper surface. The hind wings are yellowish, thickly<br />
irrorated, principally near the base, with minute dots.<br />
The female has two black spots near the centre of the upper<br />
side of the fore wings, and in many instances an elongated<br />
patch of dusky black on the lower margin. There is a dull<br />
black mark toward the centre of the fore margin of the hind<br />
wings, in a line with the two on the upper wings. Sometimes<br />
the whole upper surface is of a pale buff or yellowish colour.<br />
The eggs are placed singly.<br />
The caterpillar is pale green, with a narrow line of yellow<br />
along the back, and an interrupted line of yellow on the lower<br />
part of each side. The head, feet, and tail are entirely green.<br />
The body is slightly striated across with the segments.<br />
This is a most variable insect, especially in the size of the<br />
spots on the upper wings; in some, in fact, they are wholly<br />
obliterated, and in others they are very large. I have a whole<br />
row in my cabinet, no two of which are exactly alike.<br />
The figures are taken from some of them—one the singularly<br />
small one already spoken of.
