7. Danais (Limnas) cJirysippus, 
Papilio ohrysippuSf Linn.^ Mus. Ulr., p. 263 (1764). 
A common butterfly of tlie open country, al though 
somewhat local, and perhaps most plentiful at Shek-py- 
Wan, or Aberdeen/' on the south shore of the island, 
where I have found the larva feeding on the naturalized 
American weed, Asclepias cnrassavica, Linn., which 
grows abundantly in waste places in Hong-Kong. This 
plant now appears to be spread throughout the Moluccas 
and the Philippine Islands, but its special butterfly, 
Aiiosia plexipfus, Linn. [Danais archippus, F.), was 
not found by me farther from its original home than 
the Island of Ternate. 
8. Euploea (Isamia) superha. 
Papilio superha, Herbst, Naturs. Schmett., v., tt. 119, 
120 (1792). 
One of the commonest and most beautiful butterflies 
in the island, occurring everywhere in wooded situations. 
I have several times seen it flying in hundreds round the 
tops of the flowering trees, late in the afternoon. In the 
gardens at " Happy Valley,^' its favourite flower is the 
Poinsettia. The larva feeds on Strophanthus divergens. 
Si woody climber of the natural order Apocynese, and has 
also been found on the imported Oleander ; the brilliantly 
gilded pupa is suspended among the leaves of the food- 
plant. Abunda.nt in December, 1891, and on to the 
following March, when a fresh brood was on the wing. 
In 1893, after the frost of January 16th and 17th, it 
disappeared entirely until May 13 th, when a few fresh 
specimens were observed. 
9. Euploea (Terpsichrois) midamus, 
Papilio midamus J Linn, (pars), Mus. Uir., p. 251 
(1764) ; Syst. Nat., i., I^, p. 765, n. 108 (1767). 
This species occurs with the preceding, and its habits 
are similar, but it is much less common. December to 
May.
