Primaries below greyish, with faint indications of the markings of the upper surface: 

 secondaries whitish ; a discocellular spot, an . Y-shaped marking on abdominal border, and a 

 dentate-sinuate submarginal line dusky: body below whitish, legs testaceous j anterior tibiae 



indistinctly banded with brown. Expanse of wings 34 millim.

Allied to C. inexlricata and cerosa : the primaries much more golden than either, the 

 dark-brown markings being confined to the base, costal border, the large patch which croi sea 

 the end of the cell and which is acutely angulatcd, and to the apex; all the other spots 

 which are brown in C. inexlricata , and partly so in C. cerosa, arc of a brassy golden colour in 

 this species : secondaries with scarcely a trace of the white distal stripes : body pale brassy 

 yellowish ; thorax greenish in the centre, with a brown longitudinal dorsal stripe. Under 

 surface brassy yellow, with greyish lines, as in C. inexlricata. Expanse of wings 27 millim. 



North-east Himalayas {Lidderdale). 



Apart from difference of pattern and coloration, this species measures about half an inch 

 less in expanse of wings than C. inexlricata ; the latter differs from C. cerosa in having ten 

 instead of eight yellow lines and stripes across the costal half of the primaries, and in the 

 dark brown spots on the border near the external angle. 



Cidaria aliena. (Plate CXX. fig. 11.) 

 Cidaria aliena, Butter, Ann. $• Mag. Nat. Hist. ser. 5, vol. vi. p. 230. n. 70 (1880). 



Nearly allied to C. aurata, of the C. corylata group. Primaries black-brown, crossed at 

 basal third and again on the disk near the outer margin by two widely diverging ochreous 

 bands, touched here and there with ferruginous, and bordered by tolerably regularly dentate- 

 sinuate white lines; a cuneiform costal apical spot and a small spot near the centre of 

 external border of the same ochreous colour, but not white-bordered ; outer border towards 

 the external angle almost wholly ferruginous; a marginal series of slender white lunules : 

 fringe ochreous, spotted with blackish : secondaries white, tinted, especially towards the outer 

 margin, with golden yellow ; fringe ochreous : body white, spotted with yellow and dark 

 brown alternately. Primaries below altogether paler than above: secondaries white, speckled 

 with dark brown, and crossed in the middle by two parallel irregularly arched dark-brown 

 lines; a blackish discocellular spot; indications of a dark brown submarginal line; veins 

 almost wholly yellow: legs brownish. Expanse of wings 31 millim.
