Plateau, not below 3,000 feet, where it occurs not very rarely 
throughout the year. 
608. # Papilio ( Zetides ) arycles, Boisduval. 
Wallace as rama. Butler. As this species occurs in the Malay 
Peninsula and in Borneo, I have no doubt that Messrs. Wallace and 
Butler have correctly recorded it from Sumatra, though we have not 
met with it. The P. rama of Felder, is a synonym of P. arycles. Since 
the above was in type I find that Rothschild has four males from 
Palembang in the south of Sumatra. 
609. Papilio ( Zetides ) agamemnon, Linnaeus. 
Grose Smith. Snellen. Hagen. Wallace. Distant. Dr. Wallace 
records this species from Malacca, Sumatra, Borneo, and Java as 
local form c. “ Size small; tail very short.” The typical form of 
P. agamemnon he gives from India, and Manilla in the Philippine Isles. 
He has figured the outline of the costa of the forewing of this species 
from Sumatra in Trans. Linn. Soc. Lond., Zoology, first series, vol. xxv, 
pi. viii, fig. 6 (1865). Rothschild records the typical form from 
Sumatra. Heer M. C. Piepers has bred it in Java, and has figured 
all stages of the larva in Tijd. voor Ent., vol. xxxi, p. 341, pi. vii, 
figs. 1-7 (1888). It is common throughout the year everywhere in 
the plains where Anona muricata and Michelia chanipaca , Linnaeus, 
the food-plants of the larvae, are found, and frequents the flowers of the 
Lantana, &c., in gardens and near houses. As the butterfly is found 
also often in the forest, some wild species of Anonacece or an allied 
plant for the larva to feed on must grow there. The full-fed larva 
exists in two varieties, a bright transparent shining green form, and a 
yellow form, both having on the first three segments (omitting the 
head) a horny tubercle with orange base one on each side of each seg¬ 
ment. The pupa, which bears a nose-like projection from the thorax 
directed forwards over the head, is green with some brownish markings, 
and is suspended by a white girdle. After 15 days the imago emerges 
from the pupa. The female butterfly prefers young low plants of the 
Anona on which to lay her eggs, as on young newly planted bushes 
four or five caterpillars are often found together. A “ variety ” of 
P. agamemnon from Western Java has been described and figured by 
Heer P. C. T. Snellen in Tijd. voor Ent., vol xxxvii, p. 71, n. 3, pi. iii, 
fig. 3, female (1890). It has all the usual macular green markings of 
the upperside of a deep ochreous colour, probably due to chemical 
action, possibly that of cyanide of potassium.
