CHALK HILL BLUE.

the fore wings of a most elegant pale metallic blue, with a
cast of white; the outer part of the front edge, and a broad
border on the outside of the wings, as also the veins, dusky
black; there is a row of black dots almost hidden by the wide
border; the fringe is white, crossed by the veins ending in
dots, and very wide, except on the front edge. The hind
wings are of a similar colour, with a similar broad border on
the outer part, the lower being removed, and shewing the
black dots distinctly, bordered by a line only of the former
on the outside; the dots are more or less ringed with silvery
white; the border at the front of these wings is broader than
on the outside; the fringe is white, and very wide.
Underneath, the fore wings are pale greyish white, the margin
defined by a dusky line, through which the veins run, and end
in dots; near the" middle, towards the base, is a black dot,
faintly ringed with white, then another larger oblong central
one, then an irregular diagonal row of the like, the middle
ones being the largest, and the lower two close together, then
another row of smaller and rather fainter ones, succeeded by
another: the fringe is white, intersected by the veins. The
hind wings are greenish blue about the base, and generally of
a pale greyish broAvn hue, the whitish grey occasionally breaking
, through, especially near the lower corner; the fringe is white,
marked off by a marginal dusky line; these wings are much
spotted with a variety of spots and dots, some of them eyed
with white, some of the loAver ones of a dull orange colour.
The female has the fore wings of a dark bronzed broAvn,
with more or less phosphorescence of blue; near the centre is
a small white spot, with a black pupil; the fringe is dull white,
the veins crossing it ending more widely: there is a row of
obscure light-coloured dots within the margin. The hind wings
are of the same ground colour, but there is more of the blue
tinge, at least in some specimens; they also have a small white
spot in their centre; the margin is dull white, crossed by the
veins, and within it is a row of black dots, partially encircled
on the inner side by orange, and these again followed, at least
in some individuals, by small bluish triangular-shaped marks.
