a dark curved subterminal line; stigmata pale rufous; claviform narrow; orbicular and reniform edged with 
white, confluent with the costal streak; the former very narrow, oblicpie; the latter narrow, angled inwards 
on median nervure to middle of cell; hindwing brownish, darker along termen; fringe pale. Sikkim, N. India.

R. gaudens Hmps. Forewing grey tinged with ochreous to beyond middle in the A, then with purplish; gaudens. 
inner and outer lines double; the inner obscure, waved; outer filled in with grey, outcurved to vein 4, then 
incurved; subterminal line pale, preceded by dentate brown marks and on costa by a brown blotch; claviform 
stigma marked at extremity by a dark dot; orbicular and reniform with grey annuli slightly defined by brown; 
the orbicular round; reniform with lower lobe dark; a dark bent median shade; hindwing whitish tinged with 
dark grey, especially on veins and along termen; the $ is without the ochreous suffusion, and shows the 
median shade stronger. At present recorded only from Java. 
R. homochroma Hmps. (Vol. 3, pi. 8 1). Forewing dull dark chocolate brown, with faint blue grey suf- homo- 
fusion; inner and outer lines slightly darker brown, double; the inner oblicpie and angled above inner mar- chroma. 
gin; the outer minutely waved, nearly vertical; subterminal line pale preceded by a deep brown line; orbicular 
and reniform stigmata of the ground colour with blue grey annuli; hindwing luteous white darker along termen, 
with grey cell spot, outer line, and slight subterminal band. Described from Yatong, Tibet: appears common 
in Sikkim and Bhutan. 
R. isochroma Hmps. (7 b). Forewing pale or dark olive rufous, with blue grey suffusion at base and termen; isochroma. 
the lines deeper, all dentate lunulate; orbicular a brown dot, reniform a brown lunule; fringe rufous; hindwing 
olive grey whitish, with grey cellspot, outer line, and subterminal shade. Described from Yatong, Tibet; but 
like the last occurs in Sikkim, Bhutan, and Kulu in N. W. India. The paler examples. — ab. rufata ab. nov. rufata. 
were taken at Tonglo, Sikkim, at 10000 feet; the Kulu examples agree with them.
