6 LEPIDOPTERA. 



notice of its occurrence in these Islands was l)y tlie late Mr. 

 J. C. Dale, who found it at Trundle Mere in the year 1819. 



In all probability it is widely distributed in Wales, since it 

 is recorded in Glamorganshire in the south, and at Dolgelly 

 in the north. In Scotland found in all suitable places to the 

 Hebrides and the Shetland Isles, and on the mountains to 

 2000 feet above the sea level ; also in all those parts of 

 Ireland in which its favourite food-plant abounds. Abroad 

 it has a somewhat northern or mountain range — North of 

 France, Germany, Finland, Lapland, Livonia, and the Ural 

 Mountain district.
