/>. Underside of the hindwings without that spot. 



e-. Postcellular (diseal) spots on the upperside of forewings thrice, 

 or more, as large as the other spots of the upperside; the 

 spot between the lower median nervules twice as Inroad as 

 the black interspace before it (as in P. agamem/non typ.).

/'. Spots on the upperside of wings not so very much different 



in size, the diseal marks on forewings being small, that 



between lower median nervules narrower than the black 



interspace before it (as in subsp. celebensis).

The two [lostcellulftr spots on the underside of the forewings, situated between 

 the median nervules, have the interior portion bare of scales, while the exterior port ion 

 is densely covered with white scales ; in the following local form these spots are 

 almost entirely bare of scales, or the outer portion is much less densely scaled, so 

 that the green and white portions of the spots are not so well defined as in typical 

 P. againemnon. In a specimen from Nias Island there are a few red scales within 

 the cell of the hindwings on the underside, and also a minute red spot in the angle 

 between the second discocellular and upper discoidal nervules. The length of the 

 tails is very variable ; in the ferii%le sex the tails are often narrowed at the base, and 

 then appear to be slightly spatulate ; males with the tails obliterated are : —

All the authors which I have looked up, e.^cept Esper, Montrouzier, and Hutler, 

 have ajjplied the name of P. aegislhus L. to a species occurring in the .Moluccas and 

 New Guinea which Dr. A. G. Butler described in P. Z. S. p. 471 (1877) as a new- 

 species, under the name of P. macrai-lanei (see n. liJti). They have lieen misled by 

 Cramer, who first figured a tsfpical P. agameninoii as P. aegis'.ns L., and afterwards 

 correcting this error made a second mistake in figuring a (piite different species 

 (now = macfarlanei Bui.) as P. aegistus. LinntVs first description is as follows : —
