cuous : the posterior wings are clouded with white 
and dark brown, the basal half darkest, and the dark 
part terminating near the middle, in an irregular 
sinuated line ; there is likewise a small ocellus cor- 
responding to that on the opposite surface. 
The caterpillar and chrysalis are both light-green, 
the former with brownish legs. 
The butterfly frequents rocky and stony places, 
and occurs rather plentifully in such situations in 
most parts of the country. The rocky sides of Ar- 
thur’s Seat, and similar localities throughout the 
south of Scotland, afford it in considerable plenty in 
certain years, and we have seen several examples 
from Sutherland and other northern counties. Among 
the numerous localities cited by English entomolo- 
gists, we may mention Newmarket, Dartmoor, Nac- 
ton Heath in Suffolk, and Lexden Heath in Essex. 
In the neighbourhood of Newcastle, Mr Wailes in- 
forms us that it is almost confined to the magnesian 
limestone, and another correspondent states that 
it is not unfrequent in stony places near Durham, 
and in Castle Eden Dean, during the month of 
July.
