25. A. SYKESi, sp. n. — Allied to A. atergatis, Westwood, and 

 A. gaekivari, E.M. Sharpe; but is distinguished from the former 

 by the much darker ground colour, and from the latter species 

 by having no transparent patch on the primaries. 



Primaries : Ground colour light chestnut-brown, the nervules 

 black, the costa, apex, and hind margin narrowly edged with 

 black, the cilia white ; the spots, which are all black and well 

 defined, are situated as follows : two in the discoidal cell, and 

 one at the end of the cell; just beyond this a transverse band 

 consisting of five spots between the nervules, the first four being 

 all united ; two small spots above the submedian nervure, and 

 one somewhat larger between the first and second median ner- 

 vules ; near the hind margin a row of black streaks situated be- 

 tween the nervules, commencing above the submedian nervure ; 

 the basal area suffused with brownish black. Secondaries : The 

 ground colour somewhat pinker in tint than that of the primaries ; 

 a distinct black border on the hind margin, the cilia white, the 

 base dusted with black, and having three distinct black spots ; an 

 uneven row of small black spots crossing the discal area, each spot 

 situated between the nervules, which are not black as in the fore 

 wing. Under side : Ground colour much lighter, the apical 

 area being paler ; all the black spots and markings as on 

 the upper surface, the hind marginal border being very narrow ; 

 near this border, situated between the nervules, are seven ochra- 

 ceous coloured spots or streaks, the second one from the costa 

 extending almost to the black transverse band on the upper side. 

 Secondaries pale in colour, the whole of the basal area thickly 

 spotted with black, and also showing some pink spots ; the black 

 hind marginal border relieved by half-circles of yellowish-white 

 spots. Expanse, 2 in. Wadelai ; January-March, 1900. 



Female. — General colour of both wings more tawny brown, 

 the black spots on the primaries similarly situated as in the 

 male, but larger, the submarginal row of streaks being more 

 suffused ; beyond the black band, on the apical side, a paler band 

 is indicated. Secondaries lighter in colour, the black spots 

 larger, and the hind marginal border broader. Under side 

 agreeing exactly with that of the male above described, the pink 

 spots on the secondaries having faded to a more ochre-yellow.
