HEATH BUTTERFLY. 49 



ford Brigg, Lincolnshire; also in Nortliumberland and Cum- 

 berland; and on Barnct Hcatli. 



Coates and Drumslieugh, Schchallion, Ben Nevis, Ben 

 Lomond, Craig Chalaacli, Ben More, the Isle of Arran, and 

 the neighbourhood of Oban, in Scotland, as also in the Shetland 

 Islands; near the lakes of Killarney, and on the mountains of 

 Donegal, in Ireland; Kinnordy, between Bala and Festiniog, 

 in Wales. 



The perfect insect occurs from the first week in June to the 

 second or third in August. 



The expanse of the wings in this species varies from an inch 

 and a half to an inch and three-quarters. The fore Avings are 

 of a fulvous brown colour, the fringe of a pale grey; near 

 the outer corner are one or more eyes, following the line__ of 

 the margin, all but one being in some specimens scarcely 

 visible. The hind wings arc rather darker than the fore ones, 

 and there is a row of faint eyes following also their outer 

 margin, at a little distance within it. An irregular band of a 

 paler colour than the general tone of the wings runs more or 

 less distinctly across them about the middle, following the same 

 course as the eyes. 



Underneath, the fore wings are nearly of the same colour 

 as their upper surface. Near the outer corner are one or two 

 dark eyes — a white dot in the centre, surrounded by a ring 

 of black, and this by one of very pale buff. These eyes are 

 followed by two or three smaller and less distinct ones, pale 

 buff with a black dot in the centre. AMthin these is an irreg- 

 ular bar of still paler buff, wider at the upper than the lower 

 part: it goes nearly, but not quite, across the wings. 



The hind wings are greyish brown at the base, and as f;ir 

 as the middle, edged by an irregular very pale buff band, which 

 runs nearly across the wing, the remainder of which is pale 

 reddish brown, in the middle of which is an irregularly-waved 

 row of eyes, each formed by a white speck surrounded by a 

 black ring, and this by a pale buff one. 



This is an exceedingly variable insect, and as may be sup- 

 posed, several so-called species have been made out of one;
