THE SMALL GARDEN WHITE. (Pieris Rapæ.)
([Plate IV]. fig. 3.)
Outwardly resembling the last in almost every respect but that of its inferior size, this species shares the gardener's malediction with its larger, but perhaps less destructive, relative; for the caterpillar of Rapæ, though smaller, bores into the very heart of the cabbage, instead of being content with the less valuable outer leaves, as Brassicæ is. From this pernicious habit the French call this grub the ver du cœur.
The colour of this caterpillar is pale green, with a yellow line along the back, and a dotted one of the same colour on each side.
The chrysalis is nearly like that of the last in shape, but of course smaller, and is of a more uniform brownish or yellowish tint.
