Four New Butterflies from the Islands of Mefor and BiaJc 351 



Length of fore wing in leucoptera : 41 — 52 mm. 



Biak, Schouten Is., June (A., C, and F. Pratt) ; a series of both 

 sexes. 



This form does not occur on Mefor, and typical leucoptera is found 

 there. 



NYMPHALIDAE. 



3. Neptis maculosa sp. nov. 



Allied to heliopolis Feld., from the North Moluccas, but quite 

 distinct. 



? . Underside with full complement of white bands and spots. 

 Fore wing with a somewhat triangular spot near end of cell, joined or 

 not joined to a basal streak. A large spot outside end of cell, rounded 

 on its inner edge and slightly produced outwardly. A subcostal spot, 

 longer than broad, in 6 before the middle, and a smaller spot below it 

 in 5 more distal. Two median spots in 2 and 3, the upper the smaller 

 and near the cell, the lower produced distad. A short oblique stripe 

 on the inner margin at the middle, and above it on the submedian a 

 small spot placed more distal. A postdiscal series of 6 spots in lb to 6, 

 somewhat pointed at their proximal edge and slightly incurved on their 

 distal edge, those in 3 and 4 a little more proximally placed. A sub- 

 marginal line broken up into 6 spots placed nearer the postdiscal series 

 than the margin. The postdiscal and submarginal markings are not 

 so sharply defined as the others. Hind wing with a narrower discal 

 band of five spots, the lower two divided by the submedian, the third 

 at base of cellule 2, the fourth elongate across end of cell, the fifth above 

 it in 5, sometimes a small spot in the base of cellule 3, all sharply 

 defined. An indistinct irregular postdiscal line, more marked below. 

 A postdiscal series of seven spots in lb to 7, the one in lb more pro- 

 ximal and the other in 6 more distal than the others. A submarginal 

 line broken up into six spots the upper one minute. 



Underside markings much as on the upper side, but enlarged. Fore 

 wing with basal streak broad, discal spot much larger than above. A 

 postdiscal bluish-white irregular line broken up by veins 2 to 5 into 

 somewhat lunate marks. A clouded grey-white spot below vein 2, its 

 lower edge curved outwards to touch the lower postdiscal spot. An 

 antemarginal line, obsolete in cellule 3, and indicated in 6 and 7 by 

 two white points. A short yellow stripe on costa at base. 



Hind wing with costa white at base. A subbasal band curved towards 

 costa. Discal band not broken up. An irregular bluish-white post-
