150 CHALK HILL BLUE.
Underneath, the Avings are similarly marked to those of the
male, but the ground colour is very much darker, the spots
much larger and more distinct, Avith white rims, and there are
some orange marks Avithin the margin of the fore Avings, and
a decided row of orange lunules within that of the hind ones.
The caterpillar is green, with yellow lines on the sides and
the back.
Many varieties of this species have occurred, the eyes being
more or less distinct, and the brown more or less diffused over
the wings of the male.
One, described as a species by Miss Jermyn, under the
name of 'Polyommatus calaethys,' has the wings "above brown,
with a blue disc and a whitish discoidal spot with a black
pupil; beneath, the posterior wings have a discoidal, white,
cinctured crescent, Avith a Avaved band of seven undulated spots
toAvards the hinder margin."
