Though I have about forty-five specimens of poli/dorus from (rermaii and Dutch 

 New Guinea, Waigeu, and Salwatty, and some hundreds from the D'Entrecasteaux 

 Islands, now before me, I cannot decide at present whether we have here one or more 

 local races. The typical godarU(tnw) Lucas, of which leodamas Wall, is a synonym, 

 has dark forewings, without a white patch on either side; the white adnervular 

 streaks, though sometimes well marked below, are always narrow, and separated from 

 each other by means of black intemer\-ular streaks which run from the outer margin 

 of the wing to the black basal area; the whitish streak behind the lower median 

 nervule on the underside is especially remarkably small. The white patch on the 

 • hindwings has the cellular spot small, often smaller than that discal spot which 

 stands before the upper median nervule; the first discal spot is small, longer than 

 broad, often ab,sent ; the second mark has a length of about 3 mm., and is mostly of 

 an oblong shape, owing to the upper median and lower discoidal veins being heavilv 

 bordered with black. Such specimens are figured by Lucas as godaiikmus and by 

 Wallace as leodamas. In many individual.s of godaiiianus the cellular and the 

 anterior discal spots on the hindwings are much shaded with black; this slight 

 aberration is, as Oberthiir informs us, papiuinns (Iberth. 



Typical godartiawis I know only from the N.W. Peninsula of New Guinea 

 (Arfak, Dorey, Ati-Ati-C)nin), and from IMysol and Salvatty-. 



At Humboldt Bay and all over German New Guinea there occurs a form which 

 is remarkable for some characters: the npperside has a peculiar bluish gloss in 

 certain lights, which is more obvious than in {y[)\Qii\ godartianus ; the black inter- 

 nervular streaks on the upperside of the forewings are not strongly pronounced, 

 which gives the wing a peculiar soft appearance ; the white streaks in the postcellular 

 region, though often but feeiily marked above, are always large below, and form in 

 most .specimens a large white i)atch, which is not interrupted by complete internervular 

 black streaks; in my darkest specimen the white is more e.xtended than in my jialest 

 e.xaxnple of godartianiis. On the hindwings above only the last two submarginal 

 spots are marked or indicated ; there is no trace of the other spots, while in most 

 specimens of godartianiis, in all specimens of polydorus, queenslandicus, etc., the 

 other submarginal spots are indicated at least by a paler brown scaling. The cellular 

 white mark is very variable, occupying almost half the cell, or being reduced to 

 a small spot ; the upper discal spot is large, mostly rliomboidal, often notched, 

 seldom reduced to a small streak; the other spots are also larger than in typical 

 godartianus, especially the posterior one; the nervules traversing the white patch 

 are \ery thinly black. 



From Waigeu I have six specimens which agree with the individuals from 

 German New Guinea, except in the black internervular streaks on the upperside of 

 the forewings being more prominent, in the submarginal spots to the hindwings
