This is the smallest British species of the genus, generally 

 measuring about an inch and a quarter across the wings. It 

 is brown, with red sub-marginal bands, more or less divided 

 into spots by the veins, and marked with four, or fewer, blind 

 eyes on each wing. In the allied form, E. epiphrou (Knoch), 

 which many writers consider to be the same species, but 

 which is very doubtfully British, the eyes are ocellated. On the 

 under side of the hind-wings, the red round the eyes, which 

 is often reduced to rings on the upper surface, is wanting. 



The Butterfly is found at a considerable elevation on some of 

 the mountains of the Lake District, and those of Scotland and 

 Ireland, in June, but is very local, and not usually very 

 abundant. The larva, which feeds on s;rass, is pale green, 

 with darker longitudinal lines, and a white line on the sides. 



IV. Hipparchia Section. 



The species of this section are very numerous throughout 

 the Palrearctic Region, and one or two groups of Hipparchia are 

 well represented in the Nearctic Region. Schatz and Rober also 

 refer the Australian genera Hetero?iympha, Wallengren, and 

 Xenica, Westwood, to this section, but these are somewhat aber-
