SOUTH-AFRICAN BUTTERFLIES. 
Llackisli markings of the fore-wings smaller and not so dark, and the freckling 
of the under side less dense. The very closely-allied STjlvicola, Boisd. (of which 
Nupta, Butler, must, I think, be considered as a variation only), from Mada- 
gascar, may be separated from Alcesia by the comparative or almost complete 
failure of the discal spot, and by the duller, narrower, inwardly more suffused 
apical border. 1 
Although I was on the look-out for this butterfly when visiting Natal in the 
summer of 1867, I found it only on three occasions, frequenting the borders of 
woods on the coast, at the Umgeni and near Verulam. It has very much the 
flight and habits of the European Leucopliasia, flitting slowly and feebly about 
the herbage in shady spots. Colonel Bowker has forwarded a good many 
examples, taken near D'Urban and Pinetown in March, April, and May ; the 
few examples that I met with were on the wing at the end of February and the 
end of March. ^ 
Mr. Druce notes (Proc. Zool. Soc. Lond., 1875, ?• 4^4) ^^^^ specimens 
of this butterfly brought from Angola by the late Mr. J. J. Monteiro were 
very small.

^ There is another form in Madagascar, of which two S s and a ? are in the South- 
African Museum, presented by Mr. E. L. Layard, who captured them, I believe, on the 
N.W. coast. It is of a singularly pure white, with the apical fuscous much reduced (espe- 
cially in the two S s), but the discal spot almost as large and rounded as in Xiphia, and with 
the under side all but pure white, and its frecklings very faint and sparse. 
^ Two D'Urban examples, forwarded by Mr. A. D. Millar, are dated 17th September 
1887.
