SATYRIDAE 
Pupa. The pupa measures 177 mm. long. The head has 
two conical lateral points. The thorax has a slight medio- 
dorsal keel, sunken at the waist; the abdomen is swollen 
and rounded in the middle, and abruptly attenuated, ending 
in a well-developed cremaster amply provided with long- 
stalked, amber-brown hooks. It varies in colour from dull 
olive-greenish buff, to brilliant green. The dark variety has 
the ground colour pale olive-green over the head, thorax 
and wings, and the abdomen buffish ; it is speckled and finely 
streaked with brown ; the neuration and inner margin of 
the wing are black ; there are also three dark blotches along 
the costal margin. On each side of the abdomen are four 
longitudinal dull olive-brown stripes, and a medio-dorsal band, 
more or less green ; a white stripe runs along the inner margin 
of the wing, bordering the black outer streak. Down the 
abdomen are two sub-dorsal rows of white tubercles ; the 
spiracles are pinkish. 
The green variety varies in intensity, some are grass-green 
and others of a brilliant pure green. The markings in both 
forms are of different shades of green. The white tubercles 
and pattern of markings are similar to those of the dark 
form. The pupa is firmly attached and suspended by the 
cremastral hooks to a pad of silk spun on a stem or blade 
of grass. The pupal stage lasts about 27 days. 
Imago. Expanse of wings in the male is 47 mm. ; in the 
female, 50 mm. Sexual difference is distinct. Female . — This 
is rather the larger, the outer margins of wings rounder, the 
pale spots usually considerably larger and the fore wings 
without the androconial scales. Male . — Here the ground 
colour is a dusky-brown with usually eleven pale straw-yellow 
spots. and blotches fairly equally distributed over the fore 
wing. There is a white-pupilled black spot near the apex, 
and a patch of androconial scales in the middle of the fore wing. 
The hind wing has two yellowish spots near the outer angle, 
also a series of sub-marginal ocellated spots, usually three ; 
these are encircled with straw-yellow; the outer margin 
is scalloped. 
The ground colour of the female is rather lighter and some¬ 
what clouded with pale bronze-brown or grey. The markings 
are similar to those of the male, but are much larger and
