dark violet-grejq internally whitish except towards tip. Forewings 
elongate, somewhat dilated, costa gently arched, apex nearly rect¬ 
angular, termen straight, vertical; violet-leaden-grey, slightly

by a short white line not reaching extremity ; upper part of central 
fascia slender, very oblique, fuscous, then somewhat enlarged and 
brownish, but terminating above apex of preceding streak; two 
pairs of white oblique strigulse from costa between these, four be¬ 
yond central fascia, and a single direct strigula before apex, these 
separated by dark fuscous, three pairs beyond central fascia sending 
very oblique leaden strigse to an upwards-oblique dark fuscous 
blotch rising from middle gf termen, suffused beneath ; four short 
obscure blackish marks indicating middle of ocellus; some slight 
white and black strigulation on termen beneath apex : cilia pale

Formosa, Kyuhabon, October (/S'. Issilci) ; 1 ex. Probably allied 
to aspiclias , and indicating the mode of formation of the pale costal 
blotch of that group.
