SOUTH-AFEICAN BUTTERFLIES. 
Eegion. Only one species is known from the Palaearctic Eegion,^ 
inhabiting Vladivostok on its extreme east. The Australian Eegion 
appears to have yielded sixteen, and the Ethiopian Eegion nineteen 
species. Of the last named, four appear to be peculiar to Madagascar, 
and one {Arhogastes, Guen.) to Madagascar and Eeunion. The five 
found in South Africa are Forestan, Cram. ; Pisistratiis, Fab. ; Anchises, 
Gerst. ; Keitliloa, Wallengr. ; and ITnicolor, Mabille. The first and 
second of these scarcely differ from each other on the upper side, but 
on the under side of the hind-wings the white band is in Pisistratus 
marked with three black spots. Anchises also presents this black- 
spotted white band, but has also two orange-red spots ; while Keitliloa 
has no white bands, but vivid orange-red spots. In ITnicolor, which is 
considerably smaller and darker, there are no markings on either side 
of the wings. Forestan and Pisistratus range very widely through 
Tropical Africa, the former also reaching Madagascar and Mauritius; 
Anchises appears to be chiefly East-African, and has been recorded 
from Aden ; Unicolor was first described from Congo specimens ; 
and Keitliloa is not known to me to have occurred beyond South- 
African limits. All five species inhabit the eastern side of South 
Africa ; and Forestan and Keitliloa penetrate as far to the south and west 
as Port Elizabeth in the Cape Colony. Anchises has been received 
from Delagoa Bay only ; Unicolor from that place and ITatal. 
The three species I have observed in life (Forestan^ Pisistratus^ 
and Keithloa) have a rapid but hustling flight, reminding one, though 
much quicker, of that of such Noctuoe as Plusia and allied genera. 
Owing to their constant visits to flowers, they are not difficult to 
capture ; when settled, they hold the wings erect, the hind pair being 
kept, however, a little more open than the fore-wings.

$ Pull pale greyish-brown, darker in hind-wing ; fore-wing with a 
slight tinge of yelloiuish-grey hasally, hind-wing with a hasi-median pale 
ochreous-yellow patch. Fore-wing : paler about middle ; some greyish- 
yellow hairs at base and on inner margin. Hind-wing : much darker 
(almost black) at and near anal angle ; central and inner-marginal area 
thickly clothed with pale ochreous-yellow hairs, mixed with greyish near 
base. Under side. — Smoother, sometimes ivith a faint violaceous gloss. 
1 Of this species, H. {Ismene) Aquilina, Speyer {Stett. Ent. Zeit, 1879, p. 500) notes that 
it is one of the few Hesperidce that exhibit a sexual distinction in the neuration ; the second 
median nervule of the fore-wings originating in the S nearer to the first than to the third, 
but in the ? just the reverse.
