are rounded ; and it is slightly sunken at the waist. The 
abdomen is much curved and rounded at the end ; the-ventral 
surface is almost straight. The colour is pearly-cream-buff; 
the head and thorax are tinged with grey, the anal extremity 
inclining to flesh colour. The pupa is speckled and blotched 
with dark brown over the head, thorax and wings. There is 
a medio-dorsal dusky streak over the thorax, and a series of 
black markings down the centre of the abdomen, also a sub¬ 
dorsal row of black spots. 
The pupa is sparsely 
speckled with light brown. 
The ventral surface of the 
anal segment is beset with 
hooks. The entire surface 
is finely reticulated and 
covered with fine white 
pectinated bristles. Ex¬ 
cept for the difference in 
colouring, the pupa ol 
Cup id0 minimus and 
Everes argiades are almost 
identical, but the head of 
the former is without the 
hairs. On the seventh ab¬ 
dominal segment, appar¬ 
ently analogous to that of 
the larva, is a honey-gland 
in the form of a large, deep 
and wide incision. The 
pupa (found wild) was 
attached head upwards to 
a grass blade by a cincture round the waist and the cremastral 
hooks embedded in a pad of silk. The pupal state lasts 
sixteen days. 
Imago. The sexual difference is distinct. The expanse of 
wings averages 24 mm., but they are very variable in size, 
ranging from about 20 mm. to 30 mm. 
Male . (Upper Side.) Smoky-black in colour, the basal 
half of the wings is dusted with silvery-blue scales ; the fringes 
are white and intersected by a dusky band on the inner half.
