262 LEPIDOPTERA. 



Galway, Sligo, Donegal and Armagh, and doubtless is very 

 widely distributed on boggy heaths. 



On the Continent it is said to assume still further varia- 

 tions, one form, from Lapland, being even smaller than the 

 allied C. Pamphilus. The paler and intermediate varieties 

 seem to be widely distributed through the mountain districts 

 of Northern and Central Europe, and the darker in the 

 Scandinavian Peninsula, in Lapland and in Northern Asia ; 

 but the richly marked and coloured varieties have hardly 

 been recorded elsewhere than in the north of England. 



[C. Arcania, L. — Upper side pale tawny, with a broad 

 dark brown border to the hind margin and apex of the fore 

 wings, and sometimes a faintly dark spot in the brown 

 margin, near the apex. Hind wings brown, darkest at the 

 margin, anal angle dashed with tawny. Underside of fore 

 wings like the upper, but with the sub-apical spot distinct 

 and ringed ; of the hind wings exceedingly pretty — orange 

 brown dusted with ashy toward the base, and having a 

 broad, irregular and much toothed, white transverse fascia, 

 before which, on the costal margin is a pale ringed, white 

 centred, black spot, and beyond it a row of similar spots, 

 ringed with orange and brown, followed by a bluish silvery 

 line parallel with the hind margin. 



Described by Stephens (Illust. 1, 69), but with doubt as 

 to its British origin; also by Curtis. A specimen, not 

 labelled as to locality, exists in the old collection of Mr. 

 Sparshall in the Norwich Museum. 



Of this species Major J. N. Still, of Seaton, Devon, says : 

 " When looking through a collection of butterflies made by 

 myself when a boy, and which had not been added to, nor 

 even opened, for a number of years, I found therein two 

 specimens of C. Armnins. I cannot account for their 

 presence in the cabinet except that I may have captured 

 them when a boy. They were placed with P. j^gcria, 

 P. Megcera, &c., and there was no other non-British species
