SCOTCH ARGUS BUTTERFLY. 203 



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, ard 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.
