rior size.

The _caterpillar_ much resembles that of the last, and feeds on
violet-leaves.

The _chrysalis_ is greyish.

The _butterfly_ is double-brooded, appearing first in May and again in
August. It is not so common an insect as _Euphrosyne_, but is met with in
similar situations, and has a range nearly co-extensive with that of the
latter.

THE GLANVILLE FRITILLARY. (_Melitaea Cinxia._)

(Plate XI. fig. 2.)

Though usually rather abundant where it occurs at all, this insect is one
of the most local of all our butterflies, and I can only find recorded
about a dozen places for it in the country. Of these, the Isle of Wight is
the great metropolis of the insect, and there, in many places round the
coast, numerous colonies have been established.

This butterfly is distinguished from the next (_M. Athalia_), which it very
much resembles, principally by the characters on the under surface.

The hind wing (beneath) is covered with alternate bands of bright
straw-colour and orange-brown, divided by black lines; and possesses in
_the marginal straw-coloured band a row of clear_ BLACK SPOTS. Another row
of black spots crosses the centre of the wing. It will also be observed
that the _hind wings_ have on _their upper surface a row of black spots_
parallel with, and not far from, the margin. The colouring of the upper
side is orange-brown with black markings.

The _caterpillar_, which feeds on the narrow-leaved plantain, is thorny and
black, with reddish head and legs. The chrysalis is brownish, marked with
fulvous tint. A highly interesting account of the habits and {136} history
of this butterfly in all its stages has been sketched from the life by the
Rev. J. F. Dawson (who has made an intimate acquaintance with a colony of
the insect at Sandown, Isle of Wight), and will be found in the
_Zoologist_, p. 1271.

The _butterfly_ first appears about the first or second week in May, and
thence continues till about the middle of June, seldom enduring till July.
It is to be looked for in rough, broken ground, such as the Isle of Wight
landslips, where plenty of the narrow-leaved plantain grows.

Other localities for the Glanville Fritillary are, Folkestone below
West-Cliff (abundant); round Dover; Birchwood; Dartford, Kent; Stapleford,
near Cambridge; Yorkshire; Lincolnshire; Wiltshire; Peterboro', Stowmarket;
and in Scotland, at Falkland in Fifeshire.
