120 DARK GREEN FRITILLARY.
dark marks near the outside edge are much paler; the tips
of the wings are paler than the rest, as are the front edges, and
there are a few minute faint silver dots near the corner, and
one very obscure one inside them. The hind wings dull green
over all their inner and larger portion, excepting towards the
upper part of the outer side, where the dull fulvous, which
succeeds the green in a wide band, runs into it. The border
is pale greenish yellow; inside this is a row of seven angular-
shaped spots, edged on their inner side, crescent-wise, with dull
green. These are followed by an irregular row of seven silver
spots on the outside edge of the green colour of different sizes and
shapes, the centre one very small, and these by about seven
other spots and dots of silver, also of different sizes and shapes,
over the base of the green.
The female expands to the width of two inches and three
quarters, or a little over; the ground colour is more dull; the
base much more extensively and more deeply darker coloured;
the dark billets are larger, and those that are open in the male
are filled up with black. The hind wings are also much darker
at the base.
Underneath, most of the marks are larger than in the male.
The caterpillar is of a blackish colour, with a whitish line
down the back, and another on the side, over which is a row
of eight small spots.
One variety of this insect has been described as a distinct
species, under the name of 'Papilio charlotta,' (Haworth,) and
'Argynnis caroletta,' (Miss Jermyn.) It has "the two costal
spots on both sides of the fore wings united, and only nineteen
instead of tAventy-one silvery spots on the under side of the
hind wings, several of the ordinary spots at the base being con­
fluent." Dr. Abbot took three specimens of this variety,
nearly all alike, near Bedford; and Mr. Dale has another, taken
near Peterborough, which on the under side represents on one
wing the character of 'caroletta,' and on the other that of
'aglaia/ thereby proving it to be, "sans doute," a variety only.
Another splendid variety, of which specimens haA^e been taken
near Ipswich and Birmingham, has "the upper surface of the
