224 LEPIDOPTERA. 



brown tinged with deep lurid red ; undersurface sooty-brown. 

 When very young, dull pale purple with black raised dots, 

 and the head, collar, and anal plate shining black ; the two 

 anterior pairs of prolegs then small and not serviceable. At 

 three weeks old these legs, though still small, have come 

 into use, and the adult colouring is being gradually assumed.

June and July ; on Arbutus uva-ursi (bearberry), A. unedo 

 (in confinement), and Vaccinium uliginosum ; feeding at night 

 and hiding by day underneath the leaves. 



Pupa apparently undescribed ; in a rounded earthen 

 cocoon. 



The moth flies swiftly in sunshine, and at that time is 

 difficult of capture. In cloudy weather it sits upon the rocks 

 on the moors and mountain-sides, or on the ground among 

 moss or lichen, which it closely resembles, and generally 

 agrees with the last species in habits, while frequenting spots 

 lower down upon the hills. It is also much less plentiful 

 and more attached to restricted localities. So far as these 

 Islands are concerned, confined to the mountains of Perth- 

 shire, Aberdeenshire, and elsewhere in the districts of the 

 Tay, Dee, and Moray. Abroad, in the Alps, and elsewhere 

 in Central and Northern Europe, but usually on mountains, 

 also in the Ural Mountain district, Russia ; and in Labrador 

 and elsewhere in the northern regions of North America.
