IV. THE MALAYAN PAPILIONIDÆ OR SWALLOW-TAILED BUTTERFLIES, AS ILLUSTRATIVE OF THE THEORY OF NATURAL SELECTION.

1. Pieris EperiacomparedwithP. Coronis (Java).
2. Thyca Zebuda""Thyca Descombesi (India).
3. T. Rosenbergii""T. Hyparete (Java).
4. Tachyris Hombronii""T. Lyncida.
5. T. Lycaste""T. Lyncida.
6. T. Zarinda""T. Nero (Malacca).
7. T. Ithome""T. Nephele.
8. Eronia tritæa""Eronia Valeria (Java).
9. Iphias Glaucippe, var.""Iphias Glaucippe (Java).

The species of Terias, one or two Pieris, and the genus Callidryas do not exhibit any perceptible change of form.

In the other families there are but few similar examples. The following are all that I can find in my collection:—

Cethosia ÆolecomparedwithCethosia Biblis (Java).
Eurhinia megalonice""Eurhinia Polynice (Borneo).
Limenitis Limire""Limenitis Procris (Java).
Cynthia Arsinoë, var.""Cynthia Arsinoë (Java, Sumatra, Borneo)

All these belong to the family of the Nymphalidæ. Many other genera of this family, as Diadema, Adolias, Charaxes, and Cyrestis, as well as the entire families of the Danaidæ, Satyridæ, Lycænidæ, and Hesperidæ, present no examples of this peculiar form of the upper wing in the Celebesian species.
