THE SMALL MOUNTAIN RINGLET 
53 
medio-dorsal longitudinal stripe, bordered on either side by a 
whitish-green line. It is boldly marked longitudinally with two 
conspicuous dull white stripes on each side ; the first is sub¬ 
dorsal and bordered on each side by a darker green line ; the 
second is lateral and stands out in strong contrast against the 
darker green ventral surface ; midway between these two 
stripes is a faint and fine whitish-green line, and another 
broader subcutaneous line of the same colour immediately 
below the spiracles, which are small and have a pale yellow 
anterior blotch. The legs are pale olive and the claspers 
green. The entire surface is granular and sprinkled with 
minute black claw-like points, each rising from a pale spot. 
In the last stage the larvae frequently feed during the day, 
but mostly so at night. The larval state lasts 288 days. 
Previous to 1913, when I succeeded in rearing this species 
through all its stages, and then published full descriptions of 
its life history, the larva in its last stage was unknown ; 
therefore I have given above a detailed description of the 
fully-grown larva. 
Pupa. Pupation usually takes place towards the latter 
part of May. The pupa is from 10 mm. to n mm. long. 
Side view : the head is rather square in front, the thorax 
rounded and the meta-thorax sunken ; the abdomen is swollen 
at the middle, conical and tapering ; the anal segment ends 
in a long decurved cremaster without any hooks. Ventrally 
the wings and abdomen form a continuous curve. The ground 
colour varies from light yellow-green to cream colour. The 
head, thorax and wings are streaked with olive-brown ; the 
abdomen is speckled with olive and dusky .dots. Being 
without the usual cremastral hooks for suspension, the pupa 
merely rests low down among the grass stems, which are loosely 
spun together, forming a very frail and slight cocoon-like 
structure. 11 remains in the pupal state about twenty-one days. 
Imago. The average expanse of wings in the male is 
35 mm., in the female 38 mm. Sexual difference is slight ; 
the female is larger than the male, also rather lighter and 
more ruddy in colour ; the legs and antennae are whiter than 
in the male. 
The colour is a deep velvety brown ; a sub-marginal fulvous 
band runs parallel to the outer margin of both fore and hind
