ocelli of the hind wings, though small, are distinctly marked. A 

 second much-worn female, taken in the same locality on 22nd 

 February, appears to resemble the first very closely.

All the examples (two from Christmas Pass and twelve from 

 Mineni Valley) have the underside ocelli strongly or very strongly 

 developed, a feature which, as I have pointed out (S.-Afr. Butt. iii. 

 p. 395), is characteristic of the summer or wet-season form of this 

 Mycalesis. The specimens in all respects agree with the tropical 

 type-form more closely than with extra-tropical examples, one 

 character being the feeble expression of the ocelli on the upperside 

 of the fore wings, which in two of the males are obsolete, and a 

 second the more strongly-marked common pale median streak on 

 the underside.

Of nine specimens (six males and two females from Mineni 

 Valley and one male from Christmas Pass) taken from 27th 

 February to 26th March, all but one — a female from the former 

 locaHty captured on 12th March — are of the typical smaller and 

 darker form, with largely-developed underside ocelli, which is 

 characteristic of the summer or wet season. All the dated material 

 obtained on the Natal Coast by Mr. A. D. Millar and myself and 

 at Delagoa Bay by the Eev. H. Junod confirms Mr. L. de jSTiceville's 

 discovery at Calcutta, that in this widely-distributed and highly 

 variable species there are two well-marked seasonal forms, viz. 1 , 

 a summer or wet-season race, superiorly duller but inferiorly with 

 well-developed and conspicuous ocelli, and possessing non-augulated 

 or but shghtly angulated fore wings ; and 2, a winter or dry-season 

 race, superiorly brighter, more or less rufous, but inferiorly with 

 very imperfect, reduced, and obsolescent ocelli, and possessing 

 well-angulated fore wings. As in the case of Mr. Selous's 

 example just referred to, occasional specimens of the dry-season 

 form are met with in the wet season, and vice versa, ; but these are 

 so very few that they can only be regarded as accidentally late 

 survivors of the preceding, or early precursors of the succeeding 

 generation.

There are only two examples of this striking form, both males —
