On the phenomena of variation and geographical distribution as illustrated by the Papilionidæ of the Malayan region

by Alfred Russel Wallace

Plate II.

Represents the various forms of Papilio Pammon (figs. 1, 3, 5, and 6) and P. Theseus (figs. 2, 4, and 7). (See pages 6, 7, 51, 52, and 53.) N.B. The left side of each figure shows the upper surface, and the right side the under surface of the same insect.

Fig. 1. Papilio Pammon; a male, from Malacca.

Fig. 3. The first form of female, closely resembling the male, from India.

Fig. 5. The second form of female (P. Polytes, L.), from Singapore. This is the most common and widely distributed form of female, occurring everywhere with the male.

Fig. 6. The third form of female (P. Romulus, Cr.), from India.

Fig. 2. Papilio Theseus, the first form of female, almost exactly resembling the male, from Timor. This form is very rare.

Fig. 4. The second form of female, from Timor.

Fig. 7. The third form of female (P. Theseus, Cr.), from Sumatra. The second and third forms of female seem about equally plentiful, but are generally confined to separate islands. A fourth form of female (P. Melanides, De Haan) would have been figured, but could not be brought on to the plate. (See pages 7 and 53.)
