89 
Primaries below greyish, with faint indications of the markings of the upper surface : 
secondaries whitish ; a discocellular spot, an A^-shaped marking on abdominal bol der, and a 
dentate-sinuate submarginal line dusky : body below whitish, legs testaceous ; anterior tibiae 
indistinctly banded with brown. Expanse of wings 34 millim.

Cidaria aurigena. (Plate CXX. fig. 10.) 
Cidaiia aurigena, Buthr, Ann. Mag. Nat. Hist. scr. 5, vol. vi. p. 230. n. 69 (1880). 
Allied to C inextricata and (srosa : the primaries much more golden than either, the 
dark-brown markings being confined to the base, costal border, the large patch which crosses 
the end of the cell and which is acutely angulated, and to the apex ; all the other spots 
which are brown in C. inextricata, and partly so in C. (erosa, are of a brassy golden colour in 
this species : secondaries with scarcely a trace of the white discal 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. inextricata. 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. inextricata ; the latter difl'ers from C. carosa 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. (PlateCXX.fig.il.) 
Cidaria aliena, Butler, Ann. 6f 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 Avhite, 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. 
Bhotan [Lidderdale).
