170 Mr. G. F. Mathew’s life-histories of 
the first moult a few small orange blotches appear upon 
the back. The half-grown larva is very handsomely 
mottled with orange, yellow, and reddish brown and 
black. When it is full-grown it is 40 mm. long, with 
the third, fourth, and fifth segments rather thickened ; 
ground colour sage-green, faintly tinged with yellow; a 
series of small pale yellow spots on each side of the 
dorsal line, and immediately below, and a little in front 
of them, a subdorsal row of spots of the same colour, 
but shghtly larger; these spots on the fourth segment 
form a short transverse stripe; spiracles minute, pale 
yellow, enclosed in a black ring; just below the spiracles, 
from fifth to seventh segments, a small orange-red spot ; 
lateral skinfold well-developed, creamy white, and 
forming a conspicuous stripe; anal flap, claspers, and 
ventral surface pale greenish white; head bluish green, 
with a treble series of light-coloured (V-shaped markings 
on the face; a small black orange-tipped tubercle upon 
each side of the second segment just behind the head, 
and two of the same colour upon the thirteenth segment 
just above the anal flap; segmental divisions well- 
defined; nuchal tentacles rather short, thick, and 
salmon-coloured. 
When full-grown the larva attaches itself to a stem of 
its food-plant, and changes to a rather slender and 
slightly angulated chrysalis of a pale greenish yellow 
colour. 
At Port Moresby the butterfly frequented open waste 
places on hill-sides facing the sea. I never met with it 
in the forest. 
Papilio indicatus, Butl. (Pl. VI., figs. 8, 3 (a), & 3 (bd) ). 
I met with this rather commonly at Thursday Island, 
in Torres Straits, in April, 1885. At Port Moresby, in 
New Guinea, it was one of the most abundant species 
during our visit in November, 1884, and I succeeded in 
finding the larve and breeding a good series. One day 
while we were at anchor (we were nearly two miles from 
the landing place), a constant stream of butterflies passed 
the ship, flying across the harbour from south-east to 
north-west, the harbour being from three to four miles 
wide. Many thousands must have passed during the 
day, and three-fifths of them consisted of this species,
