Rhopalocera from the Australian region. 178 
The egg is in most cases placed on the underside of 
the leaf, near its edge, though in several instances I 
noticed them upon the upper surface, or upon the ter- 
minal shoots. It is moderately large, and perfectly 
smooth and globular, and when freshly laid is pale straw 
colour. By the fourth day it has become of a darker 
hue, and a dusky shade begins to appear on one side, 
and this gradually deepens until by the ninth or tenth 
day it is almost black, the remaining portion of the egg 
assuming different shades of French gray. With a 
pocket-lens the young larva can be faintly seen within 
the shell. On the tenth day the larva emerges, and for 
a short time remains perfectly motionless as if to recover 
its strength after the exertion of gnawing its way to the 
outer world. When it has sufficiently rested, it turns 
round and deliberately devours the remains of its shell. 
~ It then wanders about for a little while, but does not 
often quit the leaf upon which it was born; but when it 
has satisfied itself with its examination it spins a little 
pad of silk on which to secure a firmer foot-hold ; from 
this it proceeds to the edge of the leaf, where it nibbles 
its first repast, and this it continues to do as often as it is 
hungry, crawling backwards and forwards from its silken 
pad to the margin of the leaf. 
When first hatched the young larva is about 8 mm. 
long ; black, with the exception of the dorsal portions of 
the second, third, sixth, seventh, twelfth and thirteenth 
segments, which are white; head shining black. The 
whole larva seems to be covered with fine hairs, but, upon 
being viewed through a lens, these appear to be minute 
fleshy spines, though there are undoubtedly fine hairs 
interspersed amongst them. The third and fourth seg- 
ments are considerably thickened. 
The full-grown larva is 62 mm. long, somewhat cylin- 
drical, and with the fourth and fifth segments consider- 
ably thickened. It is soft and flabby to the touch. 
Upper surface pale green, or greenish olive, mottled and 
streaked with darker shades of green ; this ground colour, 
upon approaching the spiracular region, becomes of a 
golden, or golden-olive hue ; a deep madder-brown stripe 
runs from the mouth below the spiracles to the fifth seg- 
ment, when it turns obliquely upwards, and passes over 
the back, forming a broad conspicuous ring, the posterior 
part of which is of a deeper and more velvety shade
