72 Messrs. J. J. Joicey and G. Talbot on 



patch extending to inner margin near base ; a short notch of black 

 ground-colour at origin of vein 7. 



Underside. Fore-wing with well-marked costal spot and tri- 

 angular basal spot; apical spots more distinctly connected, and 

 spot below vein 3 better developed than above. Hind-wing with 

 one basal spot. 



$. Fore-wing with spots larger and apical spots generally markedly 

 connected. 



One $ specimen shows a darkening on the hind-wing of veins 16, 

 2 and 3, and a dark spot at lower angle of cell. Another example 

 shows on the fore-wing a much-enlarged cell-spot above which is 

 a costal streak; the lower median spot is also large. There are 

 5 specimens in the Tring Museum from Korrido which probably 

 belong here, in which the hind-wing shows a further extension of 

 the darkening described in the specimen above. There is a speci- 

 men in the British Museum from Biak, collected by Doherty. 



A long series of both sexes was obtained.

 8. Atella alcippe interposita, subsp. nov. 



This form connects cervina, Butl., from Dutch New 

 Guinea, with denosa, Fruh., from the Bismarck Islands. 



cj $. Upperside with a well-defined and broader black margin 

 the edge of which is nearly straight. Fore-wing with cell-markings 

 and bar beyond cell well defined; small spots at base of cellules 1, 

 2 and 3. Hind-wing with distinct basal lines. 



Underside more uniformly pale brown than in cervina, and in one 

 specimen only is the distal area darkened with bluish-grey. The 

 basal lines are well marked and the post-discal and submarginal 

 lines are more narrowly margined with bluish-grey. 



The $ is duller and more strongly marked on both sides. 



A series of both sexes. 



9. Parthenos sylvia intermedia, subsp. nov. 



(Plate IV, fig. 3, <J.) 



This form appears transitional between Moluccan forms 

 of sylvia, Crm., and tigrina, Voll. The basal brown on both 

 wings is dull- and not yellow-brown as in tigrina. 



c$. Fore-wing with the spot in 2 smaller than in allied forms, spot 

 in 5 shortened proximally, the one in 6 larger and extending the
