and agenor-'i , it will be iiiuch more convenient to accept two ? ?-forniae, a tailless 

 and a tailed form, each including a great number of aberrations, than to enumerate 

 several dozens of abenations as ? ¥ -formae. 



(a) : P. memnon L., forma typ. [cJ, $ , metam.]. 



S- The streaks of greyish blue scales on the upperside of the hindwings are 

 extended inwardly us far as the apex of the cell ; the cell is entirely black, or there are 

 greyish blue scales in the apex along the veins, or the apical third is covered with 

 greyish blue scaling ; this latter character occurs chiefly in Nias specimens. The 

 black interspaces between these streaks are somewhat dilated at their outer end, so as 

 to form a series of submarginal black spots which con-espond to the sulimarginal 

 spots of the underside. Below, the gi'ey, or bluish grey, or huffish streaks of the 

 forewings are longest and broadest in the Xias examples, shortest and thinnest in 

 those from Borneo. The bluish grey area of the hindwings is broadest again in the 

 Xias individuals, where this area extends mostly far beyond the inner row of black 

 spots, which sometimes is, however, also the case in specimens from other localities; 

 near the anal angle there is not often a tint of ochreous. 



? . Dimorphic. Very variable in pattern. 



(«') : ?-f. Uiomedon Cramer, I.e. Tailless. The principal aberrations, whicli 

 partly have received names, are as follows: — 



(((.'-) : Typical coloration. Above, forewings with red basal patch ; hindwings 

 without white, lighter in the outer half than at the base, with a series 

 of submarginal and another series of fainter subdiscal black spots ; 

 abdomen blackish. 



Qy): Like («-), but forewings with a large subapical white iiatcli. 



{c^ : ? -ab. erebiniw Haase, I.e. 

 P. laomrilon var., De Haan, L<: t. 3. f. 2 (1840). 



Like (/)-), Imt hindwings above coloured almost as in tlie rntile, with a yellow 

 mark at anal angle ; posterior half of abdomen yellow. 



(dr): Like (6^), but abdomen as in (c). 

 («') : ? -ab. mieeus Cramer, I.e. 

 Like («'), but patch at base of forewings white or yellowish white instead 

 of red. 



(/-') : 'i -ah. javanus Haase, I.e. 

 P. acliates var., De Haan, I.e. t. 3. f. 3 (1840). 



Hindwings with the apex of cell, and six or seven spots round cell white; discal 

 series of black spots absent above, as in the following aberrations. 



((/): Wallace, I.e. t. 1. f. 2 (1865). Like (/■), but cell of hindwings 

 without white. 



(k'): Hindwings white, base and a series of submarginal spots black; 

 abdomen black. 



(i^) : Like {h-), but abdomen yellow, with a dorsal black median line.
