acuter inferiorly, edged interiorly with red and preceded by a whitish 
streak. Cilia greyish or vinous-greyish, with white inter-nervular inter- 
ruptions. 
^ Duller and paler. Fore-wing : basal area more decidedly tinged 
with ochrey-yellow ; a rather suffused macular orange ray from sub- 
costal nervure near apex joining discal orange on third median nervule. 
Hind-wing : basal and inner-marginal area much suffused with ochrey- 
yellow ; orange band less macular, more continuous, not so dentated by 
nervules, suffused on its inner edge. Under side. — As in $. Hind- 
wing : discal macular silvery streak more completely interrupted on 
first and second subcostal nervules. 
A $ sent to mo from the Transvaal by Mr. David Arnot is considerably 
larger than usual, expanding 2 in. 7 lin. ; the orange of the fore-wing, and to 
a rather less extent that of the hind-wing, is extended basewards and mingled 
imperceptibly with the ochrey-yellow suffusion, and the silvery markings of 
the under side are much enlarged and conspicuously whiter than usual. 
The fore-wing in Malagrida has scarcely any trace of hind-marginal sub- 
apical prominence in the $ , and none at all in the $ . This, together with 
its smaller size, very restricted field of orange in both wings, and the continuous 
and comparatively regular course of the discal silvery streak on the under side 
of the hind-wings, readily distinguish it from its allies Wallengrenii and Argy- 
raspis, Trim. It is also very noticeable that the anal-angular projection of 
the hind-wing is very short, and that on first median nervule scarcely per- 
ceptible. 
I first met with this species in March i860 on the Lion's Hill at Cape 
Town, mistaking the first example for a brightly-marked Tliyra, Linn., as it 
pitched on the ground or on stones. It is extremely local, but numerous about 
its special haunts. Though tolerably swift on the wing, it is not easily roused, 
and never flies for more than a few yards at a time ; it almost always settles 
on the ground, and I have taken several examples with my fingers. It seems 
to be strictly a late summer butterfly, as I have not met with it before the 
beginning of February or after the end of March.
