area of the hindwings, which, moreover, extends beyond tlie lower median nervule ; 

 in my c? from the Key Isknds the band just reaches that vein, as in adrastus and 

 aegeus. The anal orange-chrome spot of the hindwings is frequently present above ; 

 the submarginal spots of the underside of the hindwings vary in number; tlie series 

 is seldom complete. 



The grey scaling in the apical region of the underside of the fonnvings, bv 

 the absence of which Wallace distinguished the Waigeu examples from those from 

 New Guinea, is eipially developed in specimens from both localities; sometimes the 

 grey streaks are more, sometimes less conspicuous; seldom tliey are quite absent. 



According to the development of the white subapical band of the forewings one 

 may diffei'entiate three aberrations of the nude : — 



(«-) : Typical ormenns Guerin, I.e. 

 Band broad. 



(6') : <?-ab. pandion Wallace, I.e. 



Spots composing the band reduced in size, partly obsolete. 



(c^) : J-ab. o^Ac/Zo Grose Sniitli, /.c. 

 Band absent from the upperside. 



I liave the two first fornrs from Waigeu, all three from the mainland of \ew 

 Guinea; my cJ from the Key Islands belongs to (J-ab. pandion, those from Aru to 

 wmenns\ in one of the latter the band consists of three rather large .spots. 



¥. Polymor])hic. There are four principal forms which run into one another: — 



(fFj : ¥-ab. inornntus ab. nov. 



Forewings entirely brown above. Type from the coast near .\rfak. 



(e-) : Typical ormenibs Gucrin ; Wallace, I.e. t. 3. f. 1. 



Similar to the nvxle, but the white area of the hindwings convex interiorlv, and 

 not extended towards the base anteriorlv. 



This form seems to me to be confined to Waigeu. Oberthiir, I.e., records under 

 this name a specimen from Amberbaki, New Guinea, which has no subapical wliile 

 band on the forewings. 



(/■) • ?-ab. polydorinus Haase, I .c. ; Wallace, I.e. t. 3. f. 3. 



Similar to the ? oi P. aegeus'Don., liut the white patch of tlie hindwings does 

 not extend beyond the subcostal nervule. 



Light parts of the forewings often ratlier white: white jiatch of hindwings 

 variable in .size; submarginal chrome-orange spots also very variable. 



This form is known from A\'aigeu, Aru, Key, New Guinea, and adjacml i-lamls. 



{()-) : ?-ab. ((maiicjK Boi.sd., I.e. (syn. : onesimn.s Hew., I.e.) ; \\'allace. I.e. t. 3. f. -1. 



Outer half of the forewings, except the margins, white or whitish. Hindwings 

 very variable in pattern ; white, with base, anterior and outer borders blac'k ; with a 

 series of submarginal spots wliicli are often partly or entirely absent, sometimes 

 enlarged and confluent posteriorly, and tlien broadly connected along tlir nervules 

 with the discal white area.
