SOUTH-AFRICAN BUTTERFLIES. 
creamy-ochreouSj the nerviiles crossing border being ferruginous, with 
short white dashes from margin between them ; spots as in Fyroeis 
(occasionally two first of discal row silvery-centred) ; submarginal 
macular streak as in Fyroeis, of variable intensity. Hind-wing : pale 
brownish-ochreous, clouded with darker-brownish, and spotted with 
silvery liturce edged broadly with ferruginous ; two elongate litursB 
between costal and subcostal nervures, — another (sometimes like a V 
reversed) closing and piercing far into cell, — occasionally a small silvery 
dot both above and below this mark, — and a discal row of three double 
ones, very singularly shaped (more or less resembling reversed W's) ; ; 
hind-margin varied as in fore-wing. No black in cilia. 
$ Wings more rounded, not so dentate. Similar to 3^, but blue 
of very much less extent and duller, being mixed with blackish ; ground- 
colour rather paler and duller ; spots larger. Under side. — As in ^, 
but paler and duller. 
Aberration $ {Hab. — Cape Town). Blue suffusion of unusual bril- 
liancy and extent, completely obliterating all orange of fore-iving as ' 
well as black spots, but leaving a very broad apical and hind-marginal 
black border, edged outwardly by the usual small orange lunules ; while 
in the liind-iving the blue extends to beyond middle, but leaves a broad 
even hind-marginal border of orange. Under-side markings as usual, 
but very dark in tint. Fore-wing more acutely angulated than usual ; 
hind-wing with unusually long anal-angular projection. 
This remarkable and very beautiful " sport " of Thysbe was taken on Table 
Mountain by Herr Gross in 1865, and has been figured by Mr. A. G. Butler 
{loc. cit.) 
Another somewhat similar example was captured near Cape Town by 
Mr. E. L. Layard (I believe in 1868), and is in the South- African Museum. 
It is small (exp. 11^ lin.), and the blue is even more developed than in the 
specimen just described, leaving no trace whatever of orange in fore-wing, and 
reducing that of hind-wing to an imperfect hind-marginal row of narrow spots. 
On the under side the inner-marginal region of fore-wing is suffused with 
blackish, and metallic spots are broadly black-ringed, while hind-wing generally 
is darker than usual, with all the markings less distinct. 
The extent of the basal blue in the $ Tliysbe varies considerably in the 
Western Districts of the Cape Colony, specimens taken on the coast having it ; 
more developed than those found more inland, in which latter (from Berg River i 
Bridge, Robertson, &c,) the blue nowhere reaches beyond middle, and in the .; 
fore-wing discoidal cell is bounded by a small black spot some way before the i 
extremity. These inland $ specimens are also smaller than the coast ones, | . 
though I have not found the $ s to be so ; but the under side is in both sexes 
paler, with the ferruginous in the hind-wing much less developed. This latter 
feature in some Western examples (including one from Malmesbury) consti- 
tutes quite a broad basal space and wide hind-marginal border, leaving little i 
more than a median band of the pale ground-colour. 
In Kaffraria Proper a different variation prevails, three $ s from the Bashee 
River being of smaller size than the ordinary Western ^ s, and having the blue 
very broad, reaching in fove-imng from^ extremity of discoidal cell obliquely 
quite up to hind-marginal black border at posterior angle, and in liind-wing 
quite up to spots of discal row. The hind-marginal border is broader and more 
even than usual in fore-wing (and with no orange lunules beyond it), and in |
