52 MR. A. R. WALLACE ON THE PAPILIONIDÆ 
wants the red patch at the anal angle, and has the white patch formed of a row of spots 
all situated a little below the discoidal cell. This is the nearest approach to the first 
form. 
3rd form of female (P. Romulus, Cram. Pap. Ex. t. 49. f. A; P. Mutius, Fab., Bois, 
Sp. Gén. p. 270; P. Hector 9, De Haan). Tab. II. fig. 6. 
This not uncommon Indian butterfly I consider to be a third form of the female of 
P. Pammon. I was first led to suspect this by finding that no males of it are known 
(the male and female from Ceylon, noted in the British Museum List, I have ascertained 
to be both females), nor have I been able to find any after an examination of the chief 
collections in England. It is also to be observed that it has been received from no 
locality which is not also inhabited by P. Pammon; there is no other known Indian 
butterfly that can possibly be the other sex of it; and lastly, it agrees very closely with 
the second form of female (P. Polytes) in all its details of form, texture, and neuration; 
and though at first sight having a very different aspect, specimens are to be found which 
by a very slight modification could be changed so as to resemble that form. J am there- 
fore quite satisfied in my own mind that I am right in sinking this species into a form of 
P. Pammon. I have already stated my opinion that it mimics P. Hector, with which, 
however, it has no affinity. The resemblance was such as to induce De Haan to place it 
as the female of that species. |

Male like P. Pammon &, but smaller, and the tail always reduced to a projecting 
tooth. | 
Hab. Java, Sumatra, Borneo, Lombock, Timor (Wall.). 
Local form æ. Much larger; more falcate wings; a broad short tail. 
Hab. Macassar (Wall.) 
1st form of female. Tab. II. fig. 2. 
Like the male, but with a very slightly marked blue and red ocellus at the anal angle. i 
This is very rare in the islands. I found one specimen only in Timor, which I took “it | 
copulä” with a male almost exactly resembling it. | 
2nd form of female (P. Polyphontes $, De Haan). Tab. IT. fig. 4. | 
Like the 2nd form of P. Pammon 9; but has the pale portion of the anterior wing of l 
a much lighter colour, and not extending so far towards the base of the wing ; the white | 
spot on the hind wings is more rounded, and has always a rather large portion within the 
cell. This form is to some extent local, not existing, I believe, in Sumatra, where it is | 
replaced by the next. i 
Hab. Borneo, Java, Timor (Wal). 
3rd form of female (P. Theseus, Cr.; P. Antiphus 9, De Haan). Tab. IL. fig. 7 | 
This is well characterized by the entire absence of the white spot from the hind wingè |
