Harbour about one mile from the mainland. All the females 
were of the male-like form cyrus, Hiibn. (= pammon, L.). 
The collection contained many other species of Papilio, but 
the model of the chief mimetic female of polytes, namely 
P. aristolochiae, F., was absent. On the island of Hongkong 
Commander Walker had described the mimetic and the male- 
hke form of the female polytes as about equal in numbers 
(Trans. Ent. Soc., 1895, p. 470). With regard to the model 
P. aristolochiae, the same author stated (p. 468) that individuals 
existed in local collections, but that he had not himself taken 
the species. Mr. J. C. Kershaw, F.Z.S., in his “ Butterflies 
of Hongkong” (Hongkong and London: 1907) stated, as 
regards the Macao district, that P. polytes “is, perhaps, the 
commonest Papilio here, exceedingly numerous all through 
the wet season, and occurring every month, though scarce in 
January. The form of 2 resembling the ¢ is the common 
one here, the other form of 2 being rather scarce by com- 
parison” (p. 110.) Of P. aristolochiae the author wrote 
(p. 107), “I have never seen this insect in the neighbourhood 
of Macao, and it is very scarce at Hongkong. . . . It seems to 
have become rarer of late years at Hongkong.” 
Finally, Prof. Poulton had received a letter dated May 4, 
1913, from Dr. Adalbert Seitz of Darmstadt giving his experi- 
ence of P. polytes in the Hongkong district. Dr. Seitz had 
collected in 1890 and from June 1891 to February 1892, in 
Kau-lung, a part of the mainland opposite Victoria on the 
island of Hongkong and about a mile distant. Dr. Seitz never 
saw P. aristolochiae nor any female of polytes except the male- 
like form cyrus (= pammon). He examined all the females 
captured throughout the whole year and they were all alike.* 
At Singapore, on the other hand, Dr. Seitz collected (chiefly 
in 1892) many of the mimetic females of polytes and none of 
the male-like form. In Kandy (Jan.—March, 1902), according 
* Dr. Seitz had written further, on May 9, 1913 :— 
“‘T saw daily, when the weather was fine, a number of P. pammon 
[polytes], which is, after P. bianor, the commonest Papilio of Kau-lung 
and Hongkong. I remember having seen in one day over 20 specimens, 
and altogether I must have seen hundreds. I have collected butterflies 
for nearly 50 years and my eyesight is very strong, so that I can 
distinguish gs and @s by their flight, and of course the pammon 
[cyrus] 9s from the polytes 9s, for the two have no similarity at all.”
