158 Mr. G. F. Mathew’s life-histories of 
above the anal flap; dorsal line much darker ; spiracular 
line indistinctly defined, and pale yellowish green ; 
spiracles black, in a pale yellow ring, with a bright 
yellow dot just below each; between the spiracular line 
and base of prolegs and claspers there is a stripe of 
smoky green, from which grow a number of fine white 
hairs; ventral area yellowish green. 
When full-grown the larva crawls to the back of a leaf 
or to a twig, spins a pad of silk in which to insert the 
anal hooks, girds itself with a silken thread, and in about 
twenty-four to thirty hours changes to a greenish grey 
and slightly angulated chrysalis. In some cases, how- 
ever, the larva does not leave the leaf upon which it last 
fed, but becomes a chrysalis, quite exposed, upon its 
upper surface. A few hours before the exit of the 
butterfly the markings of the wings are plainly visible 
through the sheath. 
Callidryas Gorgophone, Fabr. (Pl. VL., fig. 7). 
This butterfly was not common at Sydney; I only 
noticed it once or twice, and took but one specimen. It 
is not easy to catch, for it usually flies at a headlong 
pace. One day, early in March, 1885, I observed a 
female flymg about a Cassia bush in the Botanical 
Gardens, and upon examining it discovered a number of 
egos, some small larve, and one chrysalis. This was the 
only bush of the kind in the gardens, though there were 
plenty of bushes of other species, C. candoleana, &c. ; 
but I could find no traces of larve upon any of these. 
I took three or four dozen larve, and found them very 
easy to rear. 
Full-grown larva 85 mm. long, cylindrical, beautiful 
apple- or grass-green, tinged below with yellow; whole 
body delicately ribbed and finely pilose; a conspicuous 
pale yellow spiracular stripe, above which, upon each 
segment, are two or three dark metallic-blue spots ; 
viewed through a lens the body is thickly covered with 
minute brownish tubercles, which give the larva a slightly 
roughened appearance ; head paler than rest of the body; 
under parts and ventral claspers pale yellowish green. 
The young larve a day or two old are yellowish green. 
They feed perfectly exposed upon the upper surface of 
the leaves, and when not feeding have a habit of keeping
