^ Orangc-rcd 2Ktlcr, in forc-iviwj much enlarged, forming a very hroacl 

 disced band, which leaves only a narroiu fuseous border along costa, apex, 

 and hind-margin to just above suhnedian nervure. Forc-vjing : basi- 

 costal orange-oclireons border paler, longer, and voider ; fuscous of 

 basal area much varied with orange-red, especially in discoidal cell. 

 Hind-wing : basal fuscous narrower, not so dark ; kind- marginal linear 

 edging obsolete. Under side. — Very much 2^aler than in $, of an 

 almost uniform rcddish-oehreous tint, without any lilac-whitish cloud-

 and adjacent metallic spots smaller, and steely ratker tlian silvery ; 

 discal traces of spots wanting ; inner-marginal orange-yellow fainter.

Tke ^ kere described is from tke interior of Natal ; tkat described 

 by Westwood from Matabeleland appears to kave been more like tke 

 $ on tke under side.^ 



Tkis ally of Harpax, Fab., is well distinguisked by tke very bril- 

 liant and conspicuous basi-costal silvery border on tke under side of 

 tke fore-wings, and tke small development or absence of tke metallic 

 spots, witk tke exception of tkose before tke middle of tke fore-wing. 

 On tke upper side Amanga lias in botk sexes a basi-costal ockreous- 

 orange border not developed in Harpax ; tke red in tke ^ is of a muck 

 more orange tint and in tke fore-wing of smaller extent, wkile in tke

I first saw a specimen of this butterfly in the year iS6o; it was in the 

 collection of the late Mr. C. J. Andel^ssoB, who took it during his exjilora- 

 tiou of Damaraland. Mr. J. A. Bell brought me a very tattered individual 

 from the same region in 1S62. It was not until 1867 that I saw a third 

 example, viz,, the Zambesi (J , in the Hopeian Museum at Oxford, described 

 by Professor Westwood (Inc. cit.) The ^ figured in the present woi-k 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.

 paler and in the reduction of the basal silvery border of the fore-wings. Mr. Selous's speci- 

 mens from tlie Tropical Interior (especially from the Tauwani Kiver) exhibit in both sexes 

 considerable variation both in depth of colouring and distinctness of markings on the under 

 faide.
