PAPILIONIN^E. 
114 
prolegs each side. Head yellow. Fullgrown, general colour bright green, a small white ocellus 
pupilled with black on each side of the fourth seg. The processes as before, but yellow, tipped 
with black. A white lateral band just above the prolegs each side. 
Pupa, not unlike that of P. antiphates , but the projection on the head is longer and 
sharper. The colour varies from shades of brown in some specimens to a general rather bright 
green in others. 
Papilio agamemnon, Linn. 
This beautiful and common insect is very numerous indeed throughout the wet season, 
and even occurs sparingly in February and December, but I have never observed it during 
January. It has just as rapid a flight as P. sarpedon , but is also very fond of flowers, and is not 
in quite such a hurry whilst feeding as the latter butterfly. There is much range in size, some 
specimens being very small, but the sexes are alike, except that the J has the fringe of white hairs 
on the hindwing, as in the two preceding insects. When resting on a leaf it usually keeps the 
wings spread, but the forewings slightly drooped over the lower pair, as is customary with other 
species of Papilio, though they sometimes rest with closed wings. 
Fig. 6, PI. XIII is from a ? taken in May. 
Egg, globular, smooth, yellowish. 
Larva, figured on PI. 4a, Fig. 10, the young stage shown below. The pupa is much like 
that of P. sarpedon> light green in colour, the spiracles marked in dusky : the head projection and 
outline of the wings marked with reddish-brown. Two indistinct yellow dorsal lines. 
The larva feeds on several plants, amongst which are ZJvaria microcarpa and Unona 
discolor , Vahl, Nat. Ord. Anonacecc y the latter a very common shrub here, and widely spread 
over the warmer parts of Asia ; Michelia champaca , whose strong-scented flower-buds Chinese 
women are so fond of wearing in their hair ; and occasionally the larva may be found feeding on 
the Custard-apple Annona reticulata , Linn. Just before pupation the larva changes to a beautiful 
hyaline or semi-transparent green. The nuchal horn is yellowish. 
Papilio xuthus, Linn. 
Not common, but sometimes occurs in some numbers near Macao in the autumn ; 
usually very scarce at Hongkong, but appearing there sporadically. It has the slowest flight of all 
the Papilionince here, but is very graceful on the wing. It is much attached to flowers, especially 
Lantana, feeding leisurely and not vibrating its wings so rapidly as most of the other species. It is 
very often in exceedingly tattered condition, but when freshly emerged it is a handsome butterfly. 
P. xuthus is common in the Chusan islands, at Shanghai and in Japan.
