OF THE MALAYAN REGION. 53 



The red spots and lunules remain ; but in some specimens only those in the anal region 

 are visible, and these have a very close resemblance to P. Antiphus. This is also a local 

 form, not occurring, I believe, in company ^vith the last.

Mil form of female (P. Melani'des, De Haan, Verh. Nat. Gesch. t. 8. f 3). 

 I consider this to be an isolated modification of P. Theseus, Cr., peculiar to Borneo. 

 It possesses all the characteristics of a female of this species. 

 Hab. Banjarmassing (Borneo) [Ley den Museum). 



N.B. The 2nd, 3rd, and ith forms of § are all tailed, as in the females of P. Fammon.

This is very closely allied to P. Theseus. The male is larger, has the caudal tooth 

 scarcely perceptible, and on the under side has "white instead of red marginal lunules. 

 The female is tailed, much larger than P. Theseus ? form 2ud, from which it further 

 differs by the white patch on the hind wings having the red markings blended with it, 

 and more prominent.

Istform of female (P. Ledebouria, Eschsch.). 



Like the male, but with a brown tinge and an obscure anal lunule. This has been 

 noticed only in the Philippine Islands. 



2nd form of female {P.Alphenor, Cr.). 

 Distribution the same as the male. 



Zrdform of female (P. Elyros, G. R. Gray, B. M. List Pap. p. 26). 



The white patch on the lower wings reduced to a small spot, or quite absent. There 

 are many varieties of this, showing very instructively how such isolated forms of female 

 as occur in the two preceding species may have been produced by simple variation fol- 

 lowed by a "natural selection" of the forms best adapted to special conditions.

Male. Upper side : — like P. Aljihenor 6 ; but the band of white spots is broader and 

 more regular, and there is a row of four white submarginal lunules, 



Under side as in P. Aljihenor ; but the marginal spots of the upper wings, and the 

 submarginal lunules of the lower wings, are larger and more distinct. 



Female quite tailless, like the male. Upper side : — like P. uilphenor $ ; but the 

 rufous ana> spots are much smaller, not forming an ocellus at the anal angle, and they 

 do not join the white central patch. 



Under side, differs from P. Alphcnor in nearly the same manner as on the upper side.
