Of fourteen examples of this species, all from Agualani, Pern, 8 c?c? are 

 ty])ical ; three others have the hindwings more or less tinged with grey, and 1 ? 

 answers to the description of IhsoiUna salapia Drnce (^1. </■ M. 1900, i. 522), 

 which must be regarded as an aberration, having a blackish marginal border 

 to the hiudwing; the remaining, two, S and ¥, have the hindwiug wholly blackish, 

 except the basal third in the ? ; in the forewing the white bands are narrower, 

 and the central area as dark as the rest of the wing. Underneath both wings 

 are dull black, the hind wing with a dusting of pale scales. They are, however, 

 evidently a dark form of anuta, which may be known as ab. J'uinipeninx.
