NEW BUTTERFLIES FROM NIAS. 99 



Neptis kahaja, sp. nov. 

 Ncpt'is ilira, Kbeil, Rhop. Ins. Nias, p. 24, v. iii. f. 14 (1884). 



^ . Upper side. Fore wing blackish brown ; cell, inner margin, 

 streaks along nervules, an irregular postdiscal line, and two sub- 

 marginal lines fuliginous, a whitish streak beyond cell, and four 

 discal triangular white patches. Hind wing blackish brown, costal 

 area widely shining grey, four fuliginous bands crossing wing, the 

 first and third from base being wider. 



Under side. Fore wing pale brown, inner margin widely shining 

 grey, cell and interspaces clouded with fuscous, a shining golden 

 patch at base of median nervules, an irregular postdiscal and two 

 submarginal fuscous lines, the space between whitish, white markings 

 as above but with a lilacine tint ; a long whitish streak within cell. 

 Hing wing pale brown slightly clouded with fuscous, three fuscous 

 bands crossing wing beyond cell and a submarginal fuscous line, two 

 whitish bands, one across centre of cell, the other postdiscal. 



2 . Upper side. Fore wing similar to male, but markings paler 

 and two additional white patches. Hind wing as in male, but with- 

 out costal shining area and bands paler and more conspicuous. 



Under side. Fore wing wants shining area and all markings of 

 both wings larger and paler. 



From N. lasara, Fruhs., this species may be distinguished 

 by fringes having no white, and from N. ilira, Kheil, by the 

 greater extent of costal shining area of bind wing in male, and 

 greater extent of white markings. 



Neptis charonideSf sp. nov. 



^ . Upper side. Fore wing black with the following white 

 markings : a long narrow streak within and triangular patch at end 

 of cell, two preapical patches with minute dash above them, a patch 

 above and a lai-ger one below middle median nervule, a point on 

 inner margin, a submarginal series of spots. Hind wing black, pale 

 on costa, an antediscal white band, a postdiscal series of white spots 

 and a submarginal pale brown line. 



Under side. Fore wing dark brown paler on inner margin, white 

 markings as above but cellular streak shorter, submarginal spots 

 larger, and beyond them a fine white line. Hind wing dark brown, 

 white markings as above but spots larger, a discal pale brown line, 

 submarginal line whitish, base of costa whitish. 



$ . Similar to male in both wings above and below, but some- 

 what larger, paler, and the white markings a little more extended. 



A race of N. charon, Butl. It may be separated from the 

 allied form from the adjacent islands by the much narrower 

 white markings.
