New Butterflies and a Moth from. Biak. 191 



In the ^ the yellow discal patch on hind wing below varies 

 from a breadth of 4*5 mm. to 9*5 mm. Two $ $ have a 

 creamy scaling over disc of forewing. 



A small series of the dark form doryca, Butl., was 

 received. There are no intermediates. 



23. Hypolimnas pithoeka fumosus, subsp. nov. 



(^. Upperside of forewing a deep smoky-brown which is darker 

 than in pithoeka ; paler at apex and along outer margin where the 

 marginal line is distinct. Hindwing with dark basal area same 

 colour as forewing, distal area much paler. 



Underside markings as in pithoeka. Ground-colour pale oliva- 

 ceous-brown except the darker posterior area of the forewing. 

 Marginal line much thinner and closer to margin. 



$. Upperside paler than (J, discal area and band of forewing 

 coloured as in pithoeka and with some reddish-brown scaling. Hind- 

 wing light olivaceous-brown, a white discal dot in 6. 



Underside as in (J but a little paler. Wliite fringe dots between 

 veins on hindwing. 



A series. 



24. Doleschallia bisaltide nigromarginata, subsp. nov. 

 This form is allied to nasica, Fruh., from Waigeu. 



cj. The wings are widely margined with black. The discal area 

 of forewing extends to vein 4, filling base of cellule 3. The costal 

 patch varies in size and in one specimen is reduced to two small 

 spots; the space between it and the cell is in another specimen 

 almost filled in with brown. Another specimen is much nearer 

 nasica in the narrower black margins, and hindwing with only 

 costa and apex black. The outer margin of forewing is more con- 

 cave, and of hindwing more straight than in other specimens. 



$. Similar to ^J. Discal area of forewing more extended, costal 

 patch larger. 



6 (^ (^, 1 $ obtained. 



25. Doleschallia noorna fulva, subsp. nov. 



cJ. Upperside of forewing with apical and outer margin narrower 

 than in typical form. The lower three apical spots are obsolete, 

 and the discocellular spot enlarged. On the hindwing the dark 

 apical margin only reaches vein 4; discal spots obsolete; sub- 

 marginal and marginal lines much less heavily marked.
