passages connected with them, which, alas! cannot be otherwise
recalled, than by the memory, too retentive, and yet not
retentive enough.
The perfect insect appears about the middle of July.
The caterpillar feeds on the broom, (Sarothamnus scoparius,)
saintfoin, (Onobrychis satica,) and other species of the clover,
(Trifolium,) and allied kinds.
In this species, which measures from an inch to an inch and
a quarter across, the fore wings are of a silvery blue colour,
the front part verging to white; there is a minute speck near the
centre, and the edge is black; the fringe white. The hind wings
are of a similar colour, but the dark edge is wider, seemingly
a tissue of spots, and the fore part has also a dark margin;
the body abov r e is clothed with silvery and blue down. "The
antenna? are black, with white rings, the upper side of the club
black, and the lower fine orange."
Underneath, the fore wings are of a pale greyish lilac tint,
the base saturated with blue; the spot shews through larger,
and beyond it is a waved row of black spots, with white rims,
the ground colour under them being paler than the rest of the
wings, followed by two rows of minute and faint ones on a pale
orange ground, followed by a black line, and this by the white
fringe. The hind wings are marked in much the same way,
but there are two additional small eyes near the base and one
at the front edge; the pale ground under the row of spots is
nearly white, followed by a band of clear orange, with a row
of dots on its inner and outer edges, the latter larger and more
distinct than the former.
The female, which is larger than the male, has the fore wings
of a coppery brown colour, sometimes faintly tinted with blue,
with a line of obscure orange spots near the margin; the fringe
reddish buff, white at the tip and on the front edge. The hind
wings are marked in a similar manner, but the row of orange
spots is larger and more distinct, and farther within the margin;
in some specimens these wings especially have a faint suffusion
of blue.
Underneath, the fore wings are dark ash grey, with a central
