23. Ergolis ariadne. 
Pajpilio ariadne, Linn., Syst. Nat., i., 2, p. 778 (1767). 
Not very common ; flies quietly along sunny roadsides, 
and settles with expanded wings on foliage. December 
to May. 
24. Gupha erymanthis. 
Papilio erymanthis, Drury, 111. Exot. Ent., i., t. iv., 
figg. 3, 4 (1770). 
A common and generally distributed butterfly, of whicli 
specimens, usually in more or less worn condition, may be 
found from December to March, when a brood of larger 
and darker examples makes its appearance. The green 
spiny Vanessa-like larva is often found on Glochidion 
eriocarpum. Champ., a common roadside shrub with 
downy leaves, and the pupa, which is very angular and 
most brilliantly gilded, is attached to the twigs of the 
same plant. Both are, however, so frequently infested 
with Ichneumons and Dipterous parasites that I never 
succeeded in rearing the butterfly, though other local 
collectors were more fortunate. 
25. Atella phalanta. 
Fapilio phalanta, Drury, 111. Exot. Ent., i., t. 21, 
figg. 1, 2 (1770). 
Rare ; occasionally taken at flowers of Lantana camera, 
in February and March. 
26. Cethosia hiblis.. 
Papilio hihlis, Drury, 111. Exot. Ent., i., t. 4, fig. 2 
(1770). 
Var./. Cethosia eurymena^ Fold., Reise Nov., Lep., iii., 
p. 384, n. 356 (1867). 
A scarce insect at Hong-Kong, occurring in gar- 
dens in March and April. It is reported to be common 
at Wag-Ian, a little rocky island some twenty miles 
to the south-eastward, where the larva is said to feed on 
a naturalized American plant, Passiflora foetida. The 
Hong-Kong specimens agree well with the form enry- 
mena, Feld,, described from the Philippine Islands.
