Pap. phoenix, Distant, Rhop. Malay., p. 340, t. xxvii, h, 
fig- 7,?. 
Occurs not rarely in Happy Valley and other 
wooded spots ; tailed examples of the 5 are rare, at all 
events during the season over which ray stay extended, 
and one form of this sex approaches very closely to the 
insect described and figured by Distant as P. phoenix. 
The ^ is much more plentiful. First seen March 5th, 
1892, more common in May. The butterfly is partial to 
shady situations, and has a strong sailing flight. 
95. Papilio protenor, 
Papilio protenor. Cram., Pap. Exot., i., t. 49, figg. 
A. B. (1779). 
Not very common ; frequents the flowers of Rhodo- 
dendron indicum and Lantana camera ; at the latter 
shrub I took two or three beautiful examples of the $ , 
which appears to be much scarcer than the other sex, on 
my last day^s collecting at Hong-Kong, May 19th, 1893. 
First observed on March 5th, 1892. Its flight is rather 
slow and heavy. 
96. Papilio helenus. 
Papilio helenus. Linn., Mus. Ulr., p. 185 (1764). 
A very common butterfly, of which stragglers are met 
with in December and January, and fresh examples were 
observed on February 11th, 1892. The larva is found 
not rarely, on the leaves of various Aurantiacese, and 
closely resembles that of the following species. The 
flight of this butterfly is strong, undulating, and very 
erratic, and it is by no means easy to secure in good 
condition. 
97. Papilio polytes. 
Papilio polytes, Linn., Mus. Ulr., p. 1 86 (1764). 
Pap. pamiuon. Linn., loc. cit., p. 189. 
This is the commonest species of Papilio at Hong- 
Kong, its time of appearance on the wing coinciding
