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

by Alfred Russel Wallace

Hab. Aru Islands, Waigiou (Wall.), Australia (Brit. Mus.).

Remarks.—The Aru specimen agrees almost exactly with the type specimen in the British Museum. The Waigiou insect is rather darker on the under surface, and has the black markings more sharply defined.

q. Eurypylus group.

106. Papilio Codrus, Cramer.

P. Codrus, Cr. Pap. Ex. t. 179. f. A, B; Boisd. Sp. Gén. Lép. p. 228.

Hab. Amboyna and Ceram (type) (♂, ♀) (Wall.).

Local form a (Gilolensis).—Differs from the true P. Codrus in having always an additional semiovate spot below the submedian nervure, and in having a small round spot on the anterior margin of the lower wings beneath: it is also rather smaller.

Hab. Batchian and Gilolo (Wall.)

Subspecies b (Celebensis).—Fore wings in the male more attenuate, with the costal margin more curved than in true P. Codrus; upper surface more green and glossy; an additional large quadrate spot on the inner margin of the fore wings. Under surface lighter brown, the whitish marks near the anal angle wanting; a dark subtriangular band across the cell of the fore wings. Rather smaller than P. Codrus.

Hab. Celebes, Sulla Islands (Wall.).
