siderable affinity to the group named Cwullia ; and 
besides other properties common to both, have this 
peculiai-ity, that when they are made to fall down 
they roU their Avings closely round them and draw 
in their legs and antennze ; a position in which they 
not a little resemble a piece of de.ad wood. The 
species figured is rather the largest of the two, 
the expansion of the wings being frequently up- 
wai-ds of two inches. The prevailing colomr is 
pale ochreous, inclining to reddish-bro^vn in many 
places. The upper wngs are striated with dusky 
lines towards the base, and the inner side is more 
or less clouded unth the same colour ; each of them 
with two approximating ear-shaped spots near the 
middle, the hinder one largest, and relieved with 
black, which emits one or two salient points directed 
backwards ; the fringe brown spotted with black. 
The hinder wings are dusky-grey, with a darker 
lunulated spot towards the base ; the fringe ochre- 
yellow. The thorax is dark-brown on the back, and 
the abdomen light reddish-ochre, obscurely banded 
jvith dark brown. 
The caterpillar is remarkably beautifiil*, the 
ground colour being a rich green, the back adorned 
with two row's of white spots, connected in pairs, 
below this a yellow line, succeeded by a series of 
small round spots, and then a red line just over the 
legs. (PI. xxu. fig. 3.) It feeds on almost every
