 stigma filled up and the reniform outlined with the same grey; hindwing fuscous with red fringe. Described 

 by Leech from a single $ from Omei-shan, W. China. — Very close to R. cerastioides Moore from N. India.

 distinct, pale grey, edged first with whitish and externally with black; submarginal line pale and distinct, 

 preceded by wedge-shaped black marks: hindwing greyish fuscous. Taken in Kashmir, as well as in 

 X. India. 



R. trigonica Alph. (10 g). Forewing pale reddish grey; the lines pale and indistinct; inner line in $ trigonica. 

 very oblique; cell redbrown; orbicular stigma a wide triangle, merged above in the costal area, its apex 

 below not reaching median vein; hindwing white, the veins and termen pinkish grey; in ab. capnoptera capnoptera.

 yellowish with dark centres; the cell black; costa with black spots; hindwing dull luteous, paler at base,
