SATYRIDM. 
stripe dark purple-green, bordered on each side by a still narrower 
yellow stripe ; these three stripes terminate before the anal points ; 
on each side are two pale yellow stripes, one above and the other 
below the pale brown spiracles ; the upper of these is bordered 
above and below with dark bluish green, and terminates in the 
anal flap, which is tinged with pink ; the lower terminates before 
the anal flap ; the ventral surface, legs and claspers are bottle- 
green.” 
Pupa. — “ Thorax dorsally convex, with a slight median keel; . . . 
the colour of the wing-cases is pale brown ; . . . the head, thorax, 
and abdomen are apple-green, sprinkled with dingy whitish green.” 
— Newman, Brit. Butt., p. 100. The larva feeds on Ilhyncospora alba 
from June to September, and then hybernates, pupating in the 
following May. 
VARIETIES. 
a. Laidion, Bkh., i. 91. — A form occurring as a variety in 
Ireland and Scotland. It has the submarginal spots of the under 
side either very small or altogether absent. 
h. Philoxenus, Esp. 78, 3. Bothliehii, Stgr. Cat. i. p. 14 ; 
Newman, Brit. Butt. p. 98, cum figuris. — Differs from the type 
jirincipally in having a second spot on the fore wings above, near 
the anal angle. The hind wings have a distinct row of five 
black spots in light rings. Under side : Fore wings with two or 
three submarginal black spots with white centres, and internal to 
them a broad white streak. Hind wings brownish grey, with a 
central white band, and a submarginal row of six or seven well- 
defined black spots with white centres, and surrounded by light 
rings, sometimes very large and distinct ; hind margins light grey. 
Times of Appearance. — June and July, and occasionally later. 
Habitat. — This form seems to be peculiar to the North of 
England, principally in Durham, Cumberland, and Yorkshire, 
frequenting mosses. Staudinger mentions Southern Holstein as a 
locality, but it is extremely probable that it is peculiar to Northern 
England. It is probably a distinct species, and is thus given by 
Newman, loc. cit., whose description is accompanied by a series of 
excellent figures, which agree in every respect with specimens 
contained in good British collections. PI. LXXVII., 3.
