2Sth March. It is of the typical form, proper to the wet season, 

 without any trace of ochre-reddish colouring on the underside.

Oue specimen only, taken in the ^Mineni Valley on Slst March. 

 This is a perfect and very large male (ea-jj. al. 2 in. 2 lin.), with the 

 inner-marginal black band of the fore wings as broadly developed 

 as in King's figure, but still marked externally between 2nd and 

 3rd median ner\-ules with a minute white spot. In the hind wings, 

 however, the costal black band does not extend below the 2nd 

 subcostal nervule, but the hind-marginal nervular black marks 

 are decidedly larger than in Klug's figure. The underside is 

 almost pure white, with the inferior submarginal black spots (3) 

 very strongly marked ; and it also presents the peculiarity of 

 blackish hind-marginal termination to the nervules, more pro- 

 nounced in the fore wing than in the hind wing.

Five males, taken in the Mineni Valley from 6th to 26th March, 

 agree thoroughly with those described by me {op. cit. p. 102) from 

 Transvaal and Delagoa Bay ; the upperside presenting fine but 

 complete black neuration of the hind wings, and the underside 

 being almost uniformly white, with no markings beyond the ter- 

 minal discoceUular dots, a faint trace in the hind wings of the 

 costal commencement of a discal ray, and (in one specimen only) 

 dusky terminations of the nervules on hind margin, 



Xorth Ovampoland must be added to the geographical range 

 of this species, Eriksson having taken six males and three red- 

 tipped females near Ovaquenyama in February and March 1891. 

 The males are rather small (one, indeed, being dwarfish) and 

 approximate the Var. A described by me in S.-Afr. Butt. iii. 

 p. 103, but on the white underside the black neuration is very 

 variable, being pretty well expressed (though very fine) in two 

 examples only, at extremities alone in two others, and wanting 

 altogether in the remaining two ; while the discal streak in the 

 hind wings is developed in but two examples, and imperfectly in 

 one of those. The females, though heavily blackish-marked on the 

 upperside, are less so than in Transvaal examples, especially as 

 regards the borders of the apical patch in the fore wings and the 

 hind-marginal border in the hind wings, the latter being macular 

 instead of continuous. Their underside is very pale yellowish, 

 with the discal ray of the hind wings dull ferruginous and not 

 strongly marked ; there is no black neuration except in one ex-
