Plateau, not below 3,000 feet, where it occurs not very rarely 

 throughout the year.

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 fore wing 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. 0. 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 champaca, 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 Anonaceai 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 beai-s a nose-like projection from the thorax 

 directed forwards over the head, is green with some brownish mailings, 

 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. 7J, n. 3,. pi. iii, 

 fio\ 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.
