Rhopalocera from the Australian region. 143 
leaves of the food-plant. The young larva has a very 
large head, out of all proportion to the rest of the body, 
shining black, very minutely punctured, and sparsely 
clothed with fine reddish brown hairs. Colour pale 
golden green inclining to rosy on two posterior seg- 
ments; dorsal line faint, pulsating, and pale rosy; a 
few stiff reddish brown bristles upon the two posterior 
segments. 
Full-grown larva cylindrical, tapering slightly towards 
each extremity; head subcordate, somewhat flattened 
and porrected, narrower than second segment; anal 
segment produced into two sharp conspicuous points. 
Ordinary colour a beautiful pea-green, but inclining, in 
some individuals, to a pale yellowish green ; a dark pul- 
sating dorsal line, bordered by a dull green stripe, next 
to which is a pale yellow-green line; an indistinct 
darker subdorsal line; whole larva tranversely wrinkled, 
especially the anterior and posterior segments; anal 
points faintly tipped with purple; under surface, legs, 
and prolegs paler; mouth black, bordered with white ; 
ocelli and spiracles very minute and black. A common 
variety of this larva has a beautiful, but somewhat 
interrupted, purple dorsal stripe. 
When full-fed the larva attaches itself by its anal 
hooks to a pad of silk, spun on the underside of one of 
the lower leaves of its food-plant, or to a neighbouring 
twig, and changes to a short, stout, and somewhat 
obtuse chrysalis, with slightly bifid head. Colour beau- 
tiful emerald or grass-green; dorsal line darker; inner 
margin of wing-sheath bright yellow; spiracles minute, 
faint yellow. 
The leaves of the Cladium possess exceedingly sharp 
edges so that it is almost impossible to search for these 
larvee without returning home with one’s hands and 
wrists considerably cut. 
Acrea andromacha, Faby. (P1 VI., figs. 14, 14 (a) ). 
This butterfly is local at Sydney, but uncertain in its 
appearance, at times being very abundant. It flies in a 
slow floating manner, and when in the net frequently 
feions death. It is very tenacious of life, and requires 
a strong and prolonged squeeze to kill it. Towards 
sunset they assemble in numbers, and are fond of
