Plate VI.

Represents four species not before figured, belonging to the most brilliantly coloured group of Eastern Papilios, and illustrating local modifications of form. N.B. The right side shows the upper surface, and the left side the under surface of the same insect.

Fig. 1. Papilio Pericles, male, from Timor (see page 45).

Fig. 2. Papilio Macedon, male, from Celebes (see page 45). This species exhibits in a marked manner the strongly arched wings characteristic of those from Celebes, as contrasted with those represented at figs. 1 and 3, from other islands (see pages 16, 17 and 18).

Fig. 3. Papilio Philippus, female, from Ceram (see page 45).

Fig. 4. Papilio Blumei, male, from the north of Celebes (see page 46). This also exhibits the arched wing, as compared with its ally from the Moluccas (fig. 3).
