NEW BUTTERFLIES FROM NIAS. 



137 



This is the Nias form of Eulepis athamas, Dru., and appears 

 to be rare. Mr. Adams has eight examples, and I cannot find 

 any previous record of it from Nias. It may be distinguished 

 from the other races of athamas, Dru., by the greater extent of 

 the black on the under side, the subterminal patch on fore wing 

 being much larger, and there is not the slightest trace of red 

 in the lunules between upper and lower median nervules on 

 hind wing. 



Charaxes vandepolli, sp. nov. 



$ . Upper side. Fore wing chestnut-brown, a wide white band 

 from just below costa to subinedian nervule, beyond this band black; 

 a blackish spot at end of cell and two black bars between upper and 

 lower median nervules. Hind wing chestnut-brown, paler on costa, 

 a waved dark line from centre of costal to subcostal nervule, a sub- 

 marginal row of white-pointed black spots, of which the two upper 

 are fused into a large patch, a small greenish patch at anal angle and 

 the two black spots here have some bluish scaling. 



Under side. Fore wing brown with a slight lilac tinge, paler on 

 the outer margin, inner margin whitish ; the following black mark- 

 ings : a spot at base, three irregular lines within, and a twin bar at 

 end of, cell, a line from base of middle median and lower median 

 nervule and a line below this nearer base, two highly irregular discal 

 lines, the inner outwardly edged with whitish, and both with diffused 

 ochreous ; interspace between cellular lines paler than ground colour, 

 outer margin greenish bordered inwardly with a narrow silvery band, 

 two obscure subapical greenish patches. Hind wing brown, with a 

 slight lilac tinge, a black bar at base, two irregular subbasal black 

 lines, the space they enclose being paler than ground colour, and the 

 outer line inwardly edged with whitish, discal lines and edging 

 similar to fore wing ; a wide lunular dark band from apex to anal 

 angle, where it narrows to a point; a submarginal series^ of small 

 black spots, surrounded by bluish, green, and white scaling, and 

 a whitish spot behind each ; outer margin ochreous, and a fine 

 marginal rich brown line. 



This is a very distinct species, somewhat resembling the 

 female of C. psaphon, Westw. The only other island form of 

 this group of Charaxes that I know in which the male has a 

 discal pale band is C. bomeensis, Butl., from Sumatra and 

 Borneo ; that species has, however, a very dark under side with 

 no ochreous markings, has also a much narrower discal band, 

 and much shorter tails. I only know of the specimen here 

 described. 



Charaxes mitschkei, sp. nov. 



$ . Upper side. Fore wing chestnut-brown, a twin black spot 

 at upper end of cell, apical third black. Hind wing chestnut-brown, 

 with submarginal row of black lunules inwardly edged with yellowish 

 the two at anal angle being white and having bluish scaling ; an 

 apical black patch containing two whitish spots. 



Under side. Fore wing shining brown, with a faint lilac tinge
