between band and apex : cilia dark fuscous, with a snow-white dot at apex,

 band, Hindwings dark fuscous ; cilia rather dark fuscous. 



Peradeniya, Ceylon, from December to March (Green) : nine specimens. 

 Specially characterized by the snow-white dot in apical cilia, instead of the

Cosmopteryx belouacma, n. sp.

 if produced ; between these a short acute-triangular orange projection not 

 reaching beyond upper spot ; a short pale violet-golden-metallic dash midway 

 between this and apex, and another at apex, with a white dash in apical cilia : 

 cilia dark fuscous, with a costal white spot on posterior edge of band. Hind- 

 wings dark fuscous ; cilia rather dark fuscous. 



Khasis, from March to May ; three specimens. Larger than cutharacma,.

 margined anteriorly by a vertical violet-golden-metallic fascia, and posteriorly 

 by two violet-golden-metallic vertical-transverse spots, lower spot wholly ante- 

 rior to upper ; between these a short fine orange line runs to termen, and from 

 close beyond this a fine silvery-white line to apex : cilia dark fuscous, with
