SOUTH-AFRICAN BUTTERFLIES. 
hind-marginal border varying in width in accordance with that of 
fore-wing, attenuated to a point at apex and anal angle, its inner 
edge irregularly dentate on nervules, and almost always exhibiting a 
considerable projection (extremely variable in size and shape) between 
second subcostal and radial nervules. Cilia mixed brownish and 
whitish in fore-wing ; whitish or yellowish in hind-wing. Under 
SIDE. — Fore-wing : hind-marginal horcler internally hlacJush, hut exter- 
nally silvery-grey stippled and clouded luith ferruginous^ which consti- 
tutes an outer border wide superiorly, and tapering to a point about 
first median nervule, and is bounded superiorly by a costal-apical 
creamy-yellow or ochrey-yellow irregular marking, the inner edge 
of which corresponds with the position of the two white or yellowish 
spots of the upper side. Hind-iving : creamy or oclireous yellow ; 
liind-nfiarginal border silvery -grey, more or less densely stippled and 
clouded luith ferruginous or ferruginous-hrown ; inner edge of border 
more irregular than on upper side, and sharply defined by a ferruginous- 
brown line, — the inward projection between second subcostal and radial 
nervules always narrower and longer, almost always extending as far as 
third median nervule a little beyond extremity of discoidal cell, and 
thence often prolonged by some ferruginous scaling so as to join an irre- 
gular compound doable spot of the same colouring between first median 
nervule and submedian nervure ; close to inner edge of border (and often 
so united with it as to enclose a small spot of the ground-colour), be- 
tween first and second median nervules, an elongate grey-and-ferru- 
ginous spot ; a larger irregular elongate mark, of the same colouring, 
on costa a little before middle, ending on first subcostal nervule ; two 
small rounded spots near base, one in cell and the other below it ; and 
a still smaller terminal disco-cellular spot. 
^ Like hut hind-marginal horder hroader (especially ahout poste- 
rior angles), of a rather duller black, and its inner edge more irregidar^ 
emitting (esptecially on second and first median nervules of fore-wing and 
third median nervide of hind-iving) much larger and deeper dentations ; 
the principal projection in fore-wing less prominent (owing to width 
of lower half of border) and excavated at extremity, and that in hind- 
wing very much broader and more truncate. Under side. — As in 
but the grey of the markings not silvery, the ferruginous-brown 
darker, the lesser markings of the hind-wing often smaller, and the 
great projection of the hind-wing border not united to the spot below 
first median nervule by ferruginous scaling. 
The $ varies very greatly in the development of the black border. 
Specimens like that figured by Hiibner, with a rather narrow border, 
are frequently met with ; while not only are numerous gradations found 
up to and beyond as broad a border as that figured by Doubleday 
(which Hewitson, op. cit., proposed to separate as U. Erxia), but instances 
are not rare of ^ s with very much narrower borders than Htibner 
^ This mavkuig is rarely (two examples) reproduced in black on the upper side.
