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 baud, and the females a discal series of 

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

 Cocytina, Blitmei, Diardii), or with sinuous markings on both wings {Puseda, 

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

 (jrey marginal band, and the females somewhat oval discal markings {Gocijtus (Satro- 

 paces), Vacillaria, AsoIm). In the third 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, Japis, Bottgeri, Flora (Macnairi), Andersoni, Stoliczlcana, 

 Maclayi).
