other, the veius being tawuy ; tail somewhat longer than in yiyaulea. In other 

 iadividnals the discal lunnles of the forewing are all separated from the black 

 border of the wing, and all the black postdiseo-submarginal patches of the hindwing 

 stand separate from each other and from the marginal bars ; snch specimens differ 

 very little from leto, but the median bars SC^ — R' of the forewing above are 

 somewhat more proximal, the median bars C — R' of the hindwing nboci' are feebler, 

 and the posterior postdiscu-snbmarginal patches of the hindwing are comparatively 

 larger. 



? . Winys abocc darker tawny orange in basal region than in yiyantea, the discal 

 Innules of the forewing almost as in stepkanus, more blackish than in giynntcci, and 

 heavier ; discal and postdiscal interspaces more orange than in ufA'phanus ; marginal 

 line of hindwing nearl}' as in stephatms, heavier and blacker than in qiqiintcfi \ tails 

 as in yigantea aud papuensis, longer than in stepkanus. 



Underside mnch darker than in gigantea, agreeing with that of steplianus, the 

 median and discal interspaces, however, more extended yellow-buff, especially the 

 former. 



Length of forewing : S, 41—45 mm.

S . Similar to the S of C/i. latona papuensis from N.W. Dutch New Guinea, 

 but differs in the following details : — 



Upperside. Forewing a little more falcate, the discal arched bars not 



black, but tawny orange, only bar SC — SC" being marked by some black scales, 

 hence these bars much less prominent than in the New Guinea races ; j)ostdisco- 



submarginal patches not touching the narrow black marginal border. Hindwing : 



postdiseo-submarginal patch C — SO" much larger than patch SC" — R', the other six 

 patches very much smaller than in the average New Guinea ? ; admargiual bars 

 tawny, npper three somewhat blackish, not prominent. 



Underside : discal arched bars of both wings less black than in the allied races, 

 discal bars SC^— R' of forewing very ill-defined, not being deeper in colour than the 

 ochraceous, triangular patches standing at their proximal side ; tawny ochraceous 

 admarginal spots of hindwing ill-defined ; tail triangular, 4 mm. long. 



Length of forewing : ? , 48 mm.

 Poulton kindly sent us for comparison mth females of latona from other localities. 



Ribbe collected this species on Arii, but where his specimens have gone to we do 

 not know. The individuals labelled Aru in the Godman-Salvin collection, now in 

 the British Museum, are ajfi/iis, which occurs only in Celebes.
