100 DUKE OF BURGUNDY FRITILLARY.
of the leaves of the primrose. They are round, smooth, shining,
and of a pale yellowish green colour.
The caterpillar is of an oval but depressed and elongated
shape; the head, rounded, heart-shaped, smooth, shining, and
of a bright ferruginous colour; the body is covered with rows
of tubercles; it is set with feathery hairs. On the hinder part
of the back there is a black dot on each joint, and on the
sides the like, but the spots less distinct. The general colour
is pale olive orange; underneath it is whitish; the feet are
rusty brown; the claws whitish. It moves very slowly, rolls
itself up when disturbed, and remains in that state a long
time. Hubner says that it changes its skin five times before
going into the chrysalis state, and that each appearance varies
considerably.
The chrysalis is suspended from the head, and is also kept
by a cord round its middle.
The figure is from one of the specimens in my own cabinet.
