stage, when I set them free. This must be their real food plant, as it 

 is indigenous and the Oleander is an introduced plant. I do not think 

 this has been recorded before. 



Sub-Family — Satyrina*. 



7. Mycalcsis medus, Fabricius [92]. — This is the rains form of 

 M. runeka, Moore [93], as Mr. de NiceVille has proved by breeding 

 from one to the other and rice versa. M. medus differs from M, 

 runeka in having the white streak on the underside less prominent 

 but the ocelli much more so ; in M. runeka they are small and 

 obsolescent. Their colour on the upperside is a uniform dark brown, 

 with an ocellus on the forewing in some specimens. These little 

 butterflies are shade-lovers, and lie hidden under the trees and 

 bushes during the day-time ; they are active and restless in the 

 morning and evening, and also when the day happens to be dark 

 and cloudy. They possess some curious and distinctive features. 

 The costal nervure is dilated at the base of the forewing in both 

 sexes. This nervure does not touch the costal or upper edge of 

 the forewing, but lies some little distance behind it. The males 

 have tufts of hair on the hindwing. They have a skipping kind 

 of flight when started from the shades they love ; they are, however, 

 easily caught and killed. 



8. Mycalesis blasius, Fabricius [96]. — This is the rains form of 

 M. perseus, Fabricius [99], but one would think it to be a quite differ- 

 ent butterfly. M. blasius has well marked ocelli and a distinct white 

 fascia on the underside of both wings, whereas in M, perseus these 

 are almost obsolete, though in some specimens of the latter there are 

 well marked spots in the position of the ocelli which are on the 

 w T ings of the former. There is a great deal more variety in the 

 markings on the underside of the wings of M. perseus than there is 

 in M. blasius. The apex of the forewing in 31. blasius is a uni- 

 form dark brown, not so dark as in the last described species, but in 

 31. perseus there is always a small ocellus on the forewing. The 

 veins at the base of the forewing are swollen in both sexes and the 

 eyes aie hairy. The males have an erectile tuft of hair, and a 

 glandular patch on the hindwing. These features are also present 

 in the two next described species. Its habits and flight are very
