SCOTCH ARGCS BUTTERFLY.

of grey, inclining to blue, in which one or two minute 
ocelli are visible. In addition to this band, the fe- 
male has the base of the wings and the hinder mar- 
gin greyish. The fringe is light brown in the male, 
but inclining to white in the female, and interrupted 
with brown. 
The caterpillar is light green, with brown and 
white longitudinal stripes ; head reddish. The egg 
is ribbed, and of a whitish colour, speckled with 
brown. 
This insect was first discovered in the Island of 
Arran many years ago, and has been found abun- 
dantly since in many parts of the country. It oc- 
curs in some plenty over a district of considerable 
extent in Dumfriesshire — near Minto in Roxburgh- 
shire — occasionally near Edinburgh, and probably 
in most of the southern counties of Scotland. In 
England, it has been found abundantly in Castle Eden 
Dean ; and Mr Wailes informs us that it exists in 
profusion in one or two places in the magnesian lime- 
stone district not far from Newcastle.
