New Butterflies and a Moth from Biak. 195 



of the band is broader. The base of both wings is paler than in 

 diana. On hindwing the white costal spot is narrower and prolonged 

 to form a discal band which is obsolete below vein 3, the space 

 between this band and the submarginal spots being as dark as 

 base of wing. 



On underside the light band is wider on forewing and straighter 

 on hindwing than in the allied form. On forewing the post-discal 

 lunulate line is bordered distally by a row of dark blurred spots 

 which in diana are placed nearer the margin and are paler. On 

 hindwing the white band fills the space between the two discal 

 lines, and the yellowish margin of outer line is much narrower 

 than in diana. 



Length of forewing : 46 mm.

$. Larger and more rounded wings. Forewing with apex broadly 

 smoky-brown and costa narrowly so ; rest of wing pure white. The

 wing as in ^ but with a broader marginal border from base of costa 

 to anal angle. 



Underside similar to ^. The white patch on forewing broader 

 and reaching vein 10. On the hindwing the white band is broader 

 between the eye-spots. 



A series of both sexes was obtained.

^. Allied to the form holof ernes, Butl., but larger and darker, 

 being sooty-brown above. Underside of forewing with 4 sub- 

 marginal spots in 2-5, the one in 4 placed a little proximal of the 

 spot above and below, the spot in 2 smaller and nearer the margin. 

 Hindwing with the submarginal spots placed more proximal than 

 in holofernes, and larger and more bluish.
