THE BUTTERFLIES OF THURSDAY ISLAND. 85 
abdominal segments ; wing-sheaths dark reddish brown, with the 
nervures well marked. ‘These larvee differed in no way from 
larvee I have taken at the Duke of York Islands and New Britain, 
and which produced the blue variety wrvilliana, Guer., and the 
usual golden-green form; and I feel quite convinced that Kirby 
is correct in referring the five Australian varieties, and several 
others from New Guinea, Woodlark Island, Batchian, &c., to 
Papilio priamus, Linn., of which there is little doubt that they 
are merely local varieties. The chrysalids are also identical. 
Those I found were attached to the midrib of a very large leaf of 
some forest tree, and sometimes ata considerable distance from 
the food of the larve. Before suspending itself, the larva takes 
care to securely fasten the stem of the leaf at its base to the 
branch of the tree with strong threads of silk. 
Papilio polydorus, Linn., one of the most abundant species 
met with. It flies in a light airy manner, generally quite straight, 
like Hurycus or Acr@a, and appears to be a particulary easy 
butterfly to catch; nevertheless it has a trick of dropping 
suddenly or twisting to one side, as one makes a stroke at it, and 
instead of having it in your net, as you confidently expected, you 
see it hurrying off among the brushwood or careering aloft far 
out of reach. P. erithoneus, Cram., one or two seen. P.capaneus, 
West., several] observed, and one or two worn specimens 
captured; young larve upon. PP. erectheus, Don., common; and 
larvee of various sizes upon orange trees in the garden of 
Mr. Chester, P.M. ‘These specimens were of the New Guinea 
form, which is larger and rather differently marked than those 
from New South Wales. P. sarpedon, Linn., several seen; a 
rapid flyer. P. agamemnon, Linn., two or three seen, and one 
captured. 
Eurycus cressida, Fabr., numerous. 
Terias australis, Wall., T'. hecabe, Linn., Terias sp., common 
amongst high grass, &e. 
Pieris ega, Boisd., one male only. 
Callidryas crocale, Cram., several. 
Danais affinis, Fabr., not uncommon in the forest, where it 
was fond of alighting upon the extremities of dead twigs, a habit 
which is common to all the Danaine. D. petilia, Stoll, common, 
but local. 
Euplea sylvester, Fabr., very common in the forest, where it
