Remarks. — -The difference between the type specimens of volcanica 

 Butler and mimica Felder is very minimal and merely consists of the 

 confluence of three terminal streaks of the forewing and a somewhat 

 distinct shape of the apical patch of the hindwing in mimica. These 

 characters are rather inconstant and vary from specunen to specimen. 

 In general, the subspecies volcanica seems to be less variable than the 

 subspecies rivularis, and no forms with the streaks of the forewing 

 widely reduced or confluent as described in the latter subspecies are 

 known for the subspecies volcanica.

Marginal streaks of forewing narrow, generaUy almost as broad 

 as white interspaces between them, or sUghtly broader; penultimate 

 costal streak not reaching imaginary Une drawn between tips of fourth 

 costal streak (counting from wing apex) and upper tornal streak; 

 orange area distributed rather far externad of this hue. Apical 

 spots of hindwing more or less separate from each other.
