SOUTH-AFRICAN BUTTERFLIES. 
there are two linear black tails of only moderate length, on each hind- 
wing ; but in the West- African group represented by R. Faunus 
(Drury), H. Antifaunus (Doubl.), and H. Lebona (He wits.), the corre- 
sponding two tails, and especially that on the submedian nervure, are 
greatly elongated, broad, and white, while there is a similar but shorter 
additional tail on the second median nervule. 
About thirty species are recorded. North India has yielded seven, 
and the Indo-Malayan Islands nine ; while only three are known from 
the Austro-Malayan Islands. Africa has as many as thirteen, but of 
these five only have been discovered in Southern Africa. The most 
widely distributed of the five are H. Philippus and H. Lara (Linn.), 
inhabiting both North and South Tropical Africa ; H. Calculus (Hopfi".) 
is really South Tropical, only just entering the South- African Sub- 
Keg ion at Delagoa Bay. H. Hirundo, Wallengr., and H. Bitxtoni^ 
Hewits., extend over a large part of Eastern South Africa, but do not 
appear to be recorded from any place within the Tropics ; both range 
into the eastern districts of the Cape Colony, but while Hirundo is not 
uncommon there, only one capture of Buxtoni so far to the south and 
west is known to me. H. Lara is the only species generally distri- 
buted throughout South Africa ; it is common about Cape Town. 
The last-named species is very unlike nearly all its congeners, the 
upper side colouring being in both sexes of a glistening pale-ferruginous, 
shot basally with a pearly gloss. At the posterior angle of each wing 
there are two or more conspicuous black spots in white rings. These 
ocelli recur less distinctly in LI. Rale (Boisd.), from Madagascar, and 
in H. Hirundo ; and these two species — but especially the latter, with 
its single long white-fringed tail at the posterior angle of the hind- 
wing — serve to connect Lara with the rest of the genus.
