DUKE OF BURGUNDY FRITILLARY. 99
It feeds on the common primrose, (Primula verts,J and
the broad-leaved primrose, (Primula elatior.J
This species varies in the expanse of its wings from a little
under to a little over an inch and a quarter. On the upper
side the fore wings are dark fulvous, crossed with three waved
and indented bars of dark blackish brown, the inner one being
the most irregular, the indentations of each meeting the next
one, forming a kind of mosaic work; the base is entirely of
the dark blackish brown colour; the extreme margin is yelloAvish,
intersected at intervals by the outside bar, which is close to
it, and immediately inside which is a TOAV of dots in the fulvous
part, which is a row of crescents formed by the extensions of
the next dark bar. The hind wings are nearly entirely of
the dark colour, the edge being a row of widely interrupted
whitish yelloAv marks, inside which is a row of fulvous crescents,
each with a black triangular-shaped dot within it, and in the
centre of the wing three fulvous dots semicircularly disposed,
between which and the base is one other, Avhich may indeed
be considered as the upper part of the curve, in the shape of
a sickle.
Underneath, the fore wings are of a paler fulvous ground
colour, the outside edge being cream-colour, indented with
brown, the centre of the wing being paler than the rest, with
two irregular short interrupted rows of large dark brown marks
on it and toAvards the inner edge and the lower corner, and
towards the tip a row of light dots partly folloAving the margin,
with one extra one between the TOAV and the tip itself. The
hind wings are of a rather darker and richer fulvous, crossed
with two irregular Avaved bars formed of large silvery cream
white spots, one near the base and the other about the middle;
the latter has some dark markings on its inner edges, and a
few more between it and the outside, on the fulvous ground
colour.
In the female there is a greater extension of the pale colour
on the upper surface of the fore wings, and the blackish broAvn
colour is darker.
The eo-gs are found solitary or in pairs, on the under side
