SATYRIDAE 
legs and claspers are all green. The larval state lasts about 
270 days. 
Pupa. The pupa closely resembles that of the Small Heath 
(C. pamphilus) but the abdomen is less curved and is slightly 
larger, measuring 11 mm. long, and is of elegant shape. The 
head is angular, the thorax slightly keeled and swollen, the 
abdomen tapering. The cremaster is knobbed and has a 
dense cluster of amber-coloured hooks, similar to those of 
C. pamphilus. The colour at first is a vivid and brilliant 
emerald-green, finely freckled with greenish-white. Along the 
inner margin of the wing is a dull olive-green streak, bordered 
on the inner edge by a whitish streak ; two other streaks run 
through the wing, one median and one near the apex. The 
pupa is suspended by the cremastral hooks to a pad of silk 
which is spun to a grass stem. The pupal stage lasts twenty- 
three days. 
Imago. The sexual difference is slight. Usually the male 
is darker in colour, otherwise the sexes are similar. The 
average expanse of the wings is 41 mm. 
Male .—The type C. tidtta has the fore wing fulvous-brown, 
the basal half being glossed with golden-brown ; there is a 
sub-apical black spot ringed with ochreous, and a smaller 
one between the second and third median nervures. The 
hind wing is a darker brown, and there is a sub-marginal 
series of similar ochreous-ringed black spots, usually three. 
The under side of fore wing is similar to the upper, but it 
has in addition an ochreous-white transverse stripe across 
the wing beyond the middle. The ocellated spots are larger, 
with white pupils. The under side of the hind wing is brown, 
clothed with greenish-grey cilia, the marginal area being 
greyish; there is a broken, irregular, whitish transverse 
median band and a sub-marginal series of six small ocellated 
spots, with white pupils and ringed with ochreous. 
Female .—This is similar but paler in colour. 
Ab. philoxenns (known as C. davus and C. rothlicbii). The 
ground colour is dark fulvous-brown, the ocellated spots are 
more distinct, and encircled with fulvous. 
Ab. laidion. The fore wing is usually light ochreous-buff, 
with a pale greenish-grey gloss along the costa and apex ; 
there is a small indistinct yellowish sub-apical spot ; the
