.06 BRITISH BUTTERFLIES. 



On the under side, the front wings are nearly the 

 same as on the upper side, showing the red patch and 

 eyes plainly ; but the hind wings are without the red 

 patch, and are divided into broad bands of brownish 

 tints, very variable, having sometimes a tendency to 

 chocolate colour, sometimes to an olive or russet brown : 

 out the stripe which is shown as lightest in the engrav- 

 ing of the under side is almost always greyer than the 

 rest, having occasionally a purplish ash colour. On 

 this band are some minute specks, occupying the placea 

 of the upper surface eyes. 



The number of eye-spots is very variable on both 

 surfaces. 



The female, which is the sex figured, is both largei 

 than the male and has the reddish band of a brighter 

 colour. 



The caterpillar, whose food plant is unknown, is 

 stated by Duncan to be "light green, with brown and 

 white longitudinal stripes ; head reddish." 



The butterfly appears in August and September. A 

 few years ago it was esteemed a rare insect, but it has 

 since been found in plenty in some of the following 

 localities, the list of which would doubtless be largely 

 added to by further research in the northern hilly 

 districts, its chosen haunts. 



Near Edinburgh; near Minto, in Koxburghshire ; 

 Isle of Arran ; Brsemar ; near Newcastle ; Castle Eden 

 Dene ; Durham ; Craven ; WharfedaJe.
