Of this rare little Neptis, hitherto only known to me as inhabiting the Durban district of Natal, there is a single example, captured at Christmas Pass on 13th February. Genus DIADEMA, Boisd. 55.

This species appears to be the solitary representative of its genus in Eastern and South-eastern Africa. Genus HAMANUMIDA, Hiibn. 57. H A M A N U M I D A D^EDALUS (Fabr.). Papilio dcedalus, Fabr.

I have for some time been disposed to think that the well-known variation in the underside of this widely-distributed African butterfly is seasonal, and these dated captures of Mr. Selous's tend to confirm this view. All the specimen taken by Mr. Eriksson at Omrora, tropical S W . Africa, from 1st to 25th August, 1887, were (as I have recorded, P. Z.
