ANISOPTERYX ASSCULARIA. 159 
back, and there is a fine blackish subdorsal Ime; 
the usual dots very small, black, and bearing pale 
yellowish short bristles; at first there is no appear- 
ance of feet on the ninth segment. As the larva 
feeds, the middle portion of the body becomes greener, 
while the head and tail are more yellowish, but after a 
little growth the green spreads throughout. When the 
larva is almost half-grown it plainly shows some rudi- 
ments of legs on the ninth segment. 
When full-grown the larva is rather over an inch in 
length, very even in bulk; the head flattish, but with 
rounded outline to the lobes; under the anal flap are 
two short, blunt points; on the ninth segment a pair 
of feet, perfectly formed, but useless for walking, 
being about one-sixteenth of the size of the pair on 
the tenth segment. The general appearance of the 
colouring is yellowish-green, owing to the number of 
green and yellow lines which run intermixed down the 
body; the dorsal line is a pale yellowish thread, 
running between two dark green lines, darkest at the 
segmental divisions, and themselves again edged with 
pale yellowish ; then on a pale yellowish-green ground 
are some pale yellow freckles; then comes the sub- 
dorsal line, yellowish, edged with decided green ; then 
more yellow freckles; then a waved, rather broken, 
supra-spiracular liné of yellow, edged above thickly 
but irregularly with green, reaching highest at the 
beginning and end of each segment, and lowest just in 
the middle above each spiracie; the spiracular region 
broadly and decidedly green, each black-ringed spiracle 
with a small yellow halo (and in some individuals 
behind each spiracle is a conspicuous spot of darker 
green); the subspiracular is a stouter undulating line 
of deeper yellow, edged in parts with dark green; the 
belly rather bluish-green; the head greenish with a 
tinge of very pale brown. 
The cocoon 1s neatly formed, of long oval shape, and 
of tough texture, being lined with close-woven 
yellowish silk, and covered with fine earth ; in fact, it
