228 LLOYD'S NATURAL HISTORY. 



mountains. It is often found in company with E. athiops on 

 the Continent, but there is no evidence that it is truly British. 

 There are two specimens in the British Museum which belonged 

 to the collection of the late James Francis Stephens, and are 

 named E. ligea. They are said to have been taken in the 

 Isle of Arran by Sir Patrick Walker; but one of the specimens 

 is not E. ligea at all, but belongs to an allied mountain species, 

 E. euryale (Esper), and this throws additional doubt on the 

 authenticity of the specimens. If the Butterfly were really 

 a native of the Isle of Arran, it could not have been over- 

 looked by the many collectors who have visited the island of 

 late years. 



The Butterfly is of a rich brown colour, with red marginal 

 bands, marked with four black eyes with white pupils on the 

 fore-wings, and three on the hind-wings. The two eyes nearest 

 the tip of the fore-wings are more or less confluent. The 

 under surface of the hind-wings is marked with an irregular 

 and interrupted white band, at once distinguishing it from nearly 

 all the other known species of the genus. It measures from an 

 inch and a half to an inch and three-quarters across the wings. 

 It flies in July and August. 



The larva is green, blackish on the back, and with white 

 longitudinal stripes on the sides. It feeds on grass in spring 

 and autumn.
