■\vhitish segmental haiuls. Forcwings linear, acute : dark t'nscous, slightlv 

 purplish-tinged ; a light ochreous-yellowish streak along fold from base to 

 middle, thence sinuate upwards, becoming thicker and proceeding close beneath 

 costa to apex, from its lower edge beyond middle sending an equally thick 

 branch to middle of terraen, slenderly connected with upper branch on termen: 

 between the two branches is a fine silvery-blue-metallic line : cilia dark fuscous 

 tinged with purplish, on costa yellowish at base, ijindwings dark fuscous. 

 ob.scurely subhyaline towards base in and beneath cell ; cilia dark fuscous. 



Khasis, in August ; two specimens, 



Cosmopteryx , Hb, 



The species of this genus, notwithstanding their distinct and beautiful colour- 

 ing, are very closely allied together, and require careful observation to perceive 

 their distinctive characters. Twenty species are here recorded and to assist 

 determination a tabulation of these is given ; but it must be remembered that 

 other closely allied forms doubtless exist ; the only other Indian species, 

 described is a^/a^/ca Stt., which I have not included as I do not yet possess a 

 specimen, though I have examined the type and consider it distinct from all 

 these ; the two other species doubtfully referred by Stainton to Cosmopteryx do 

 not belong to the genus.
