Note. — In this genus, of which the representatives are mostly Indo-Malayan, 

 there are three well-marked groups of species. In the first group, the sexes are 

 dissimilar, the males having a blue marginal band, and the females a discal series of 

 fusiform markings on both wings (Phlegethon, Ambalika, Gundava, Gopia, Monina, 

 Gocytina, Blumei, Diardii), or with sinuous markings on both wings (Puseda, 

 Ludehingii). In the second group, the sexes are also dissimilar, the males having a 

 grey marginal band, and the females somewhat oval discal markings {Gocytus (Satro- 

 paces), Vacillaria, Asolm). In the tMrd group, the sexes are somewhat similar, 

 the marginal band being present in both the male and female, either of a grey 

 or blue colour {lepida, Jajois, Bottgeri, Flora (Macnairi), Andersofti, StoliczJcana, 

 Maclayi).
