EREBIA EPIPHRON. 137 



butterfly found in Britain, for the other species of the 

 genus frequents much lower ground. It should be 

 sought for in marshy hollows on the mountain-sides in 

 Scotland and the north of England, and in one locality 

 at least has been taken at a height of 3oooft. above 

 sea-level. Its flight, which only takes place when the 

 sun is shining, is slow and interrupted. Epiphron fre- 

 quently settles and falls to the ground among the grass, 

 where the dark colour of its wings makes it a difficult 

 object to find. If possible, specimens should be obtained 

 soon after leaving the chrysalis, for the wings are very 

 easily damaged. 



In England epiphron is found in the Lake District; 

 that is, Westmoreland, the north of Lancashire, and the 

 south of Cumberland. There it has been taken in many 

 districts, of which the following have been mentioned : 

 Sprinkling and Styehead Tarns, Gable Hill, mountains 

 near Ambleside, Helvellyn, and Langdale Pikes. In 

 Scotland it has been taken at Rannoch in Perthshire, on 

 Ben Lomond and Ben Nevis, and at Loch Vennachar 

 near the Trossachs. 



The larva appears to pass the winter in a state of 

 hibernation, like the rest of the Ringlet group. The 

 perfect insects are out from about the middle of June 

 till the beginning of August, the males being a little 

 earlier than the females. Where found, epiphron is 

 usually plentiful; but very local. 



The larva, which feeds on grass, has been described 

 by Newman as pale green in colour, with numerous 

 darker green longitudinal lines shading into the ground- 

 colour, and with a well-defined white line along each 

 side in the region of the spiracles. 



The pupa, which is of somewhat stumpy proportions, 

 is light green anteriorly, and dingy white posteriorly,
