marginal) becomes silvery-scaled near anal angle ; a silvery edging along 
excavation of inner margin before projection of anal- angular lobe. 
$ Orange-red faUr^ in fore-wing much enlarged, forming a very hroad 
discal hand, vjhich leaves only a narroiu fuscous lorder along costa, apex, 
and hind-margin to just ahove subm,edian nervure. Fore-iving : basi- 
costal orange-oclireons border paler, longer, and wider ; fuscous of 
basal area mucb varied with orange-red, especially in discoidal cell. 
Hind-iving : basal fuscous narrower, not so dark ; liind-marginal linear 
edging obsolete. Under side. — Very much 'paler than in ^, of an 
almost uniform reddish-ochrcous tint, ivithout any lilac-whitish cloud- 
ing. Fore-wing : basi-costal silvery border much narrower ; cellular 
and adjacent metallic spots smaller, and steely rather than silvery; 
discal traces of spots wanting; inner-marginal orange-yellow fainter. 
Hind-ioing : markings quite obsolete, except inner -marginal silvery 
edging before anal-angular lobe. 
The $ here described is from the interior of Natal ; that described 
by Westwood from Matabeleland appears to have been more like the 
^ on the under side.'^ 
This ally of Harpax, Fab., is well distinguished by the very bril- 
liant and conspicuous basi-costal silvery border on the under side of 
the fore-wing's, and the small development or absence of the metallic 
spots, with the exception of those before the middle of the fore-wing. 
On the upper side Amanga has in both sexes a basi-costal ochreous- 
orange border not developed in Harpax ; the red in the ^ is of a much 
more orange tint and in the fore-wing of smaller extent, while in the 
^ it is unspotted in both wings. 
I first saw a specimen of this butterfly in the year i860; it was in the 
collection of the late Mr. C. J. Andersson, who took it during his explora- 
tion of Damaraland. Mr, J. A. Bell brought me a very tattered individual 
from the same region in 1862. It was not until 1867 that I saw a third 
example, viz,, the Zambesi ^ y in the Hopeian Museum at Oxford, described 
by Professor Westwood {loc. cit.) The $ figured in the present work was 
taken in 1875 in the northern part of the Transvaal by Mr. H. Barber, 
and the Natal $ just described in 1884 by Mr. J. M. Hutchinson. Mr. F. 
C. Selous met with the species at several places on the road between Bamang- 
wato and the Zambesi River. Mr, Hutchinson wrote that the specimen he 
captured (on 2 2d May 1884) was on the summit of a very lofty hill, and 
settled several times on the same stone.

1 A 9 received from Mr. T. Ayres, with the note " Between Limpopo and Zambesi 
Rivers," is coloured and marked on the under side quite similarly to the S , except in being 
paler and in the reduction of the basal silvery border of the fore-wings. Mr. Selous's speci- 
mens from the Tropical Interior (especially from the Tauwani River) exhibit in both sexes 
considerable variation both in depth of colouring and distinctness of markings on the under 
bide.
