only species as yet met with in the western districts of the Cape Colony 
is /. BoiuJceri, of which I captured several specimens at Kobertson in 
1875 and 1876; but in the eastern districts /. Silas, Sidus, Mimosm, 
and Aphnceoides occur, — the last-named being apparently of extreme 
rarity. /. Pallene is a tropical species, and has hitherto not been found 
in South Africa proper, except in Swaziland. 
Of the thirty- seven species recorded, no fewer than eighteen are 
African ; and of the rest, one is Arabian, ten are Indian, seven from the 
Malayan Archipelago, and one from some unregistered locality.

Uxp. al, ($) I in. 5-7 lin. ; ($) I in. 6-9 lin. 
$ Metcdlic piore-blue, withoid any purplish tinge. Fore-wing : blue 
forming a large semicircle ; a moderately-wide black border on costa 
becomes very broad at apex, extending thence rather broadly to anal 
angle ; inner-marginal tuft of hairs ochrey-yellow. Hind-iving : a black 
costal and hind-marginal border, rather variable in width, but becom- 
ing very narrow towards anal angle ; a more or less complete black 
streak parallel to it, between discoidal nervule and submedian nervure, 
interiorly edges two crimson-red spots between submedian and second 
median nervule ; on anal-angular lobe, a crimson, blue-dusted spot ; 
inner margin rather widely dark-grey ; tails black, white-tipped, that 
on submedian white-edged ; shining costal circular space black, filling 
nearly whole of cell. Cilia of fore-wiiig grey ; of hind-wing white. 
Under side. — Glistening ivhite ; a comr^ion, transverse, dull, crimson-red 
line beyond middle. Fore-ioing : line commencing near costa, inter- 
rupted on each nervule, not reaching inner margin, often indistinctly 
marked. Hind-wing : streak well marked, straight from coeta to second 
median nervule, where it bends outwardly, forming a spot (correspond- 
ing in position with the superior of the two spots on upper side), 
beyond which it is black, interrupted, and inclining inwards to inner 
margin ; immediately before this part of line, a similar interrupted 
black one, not reaching beyond submedian ; spot on lobe conspicuous, 
including a black spot; an indistinct greyish clouding between line 
and hind-margin, which is black-edged towards anal angle. 
$ Blue p)ale, faint, inclining to violet, not metallic, occupying a 
smaller space, so that the dark margins (which are dull-blackish) are 
broader, especially in hind-wing. Fore-wing : blue much paler on 
median nervules, occasionally almost white. Hind-iving : black streak 
^ In this figure the dentation at the extremity of the second median nervule of the hind- 
wings has been erroneously lengthened into a linear tail.
