bloom over basal half of inner margin and middle of Lind-margiu. 
Cilia of the colour of the margins alternated with whitish. 
$ Considerably ijaler, markings similar. Forc-iuing : hind-marginal 
border comparatively narrower, the space of ground-colour between it 
and discal band broader. Hind-wing : apical black not so extended, 
the discal part ending on third median nervule and the hind-marginal 
edging being narrower. Under side. — As in ^. 
Considerable variation is shown in the width and extent of the discal band. 
A S i^om Griqualand West, taken by Mrs. Barber, has the band in both 
wings much attenuated inferiorly ; and a $ from tlie same country, captured 
by myself, has it in the fore-wing very narrow throughout, and in the hind- 
wing prolonged, as in the $ , but broader. A very worn 9 , the locality of 
which is not recorded, in the South-African Museum exhibits the band in the 
fore-wing in a yet more reduced form, its upper part being very narrow and its 
lower part obsolete. 
This very distinct species has no close ally knoAvn to science. In outline 
of wings and the character of the upper-side markings it has much of the aspect 
of Chrysorycliia Ilarpax (Fab.), but, apart from its much larger size, tlie under 
side of the hind-wings has a totally different pattern, three pure-white streaks 
replacing the numerous metallic spots of that species. Structurally it has no 
near affinity to Harpax, the gradually clavate antennge, long palpi, and five- 
branched subcostal nervure of fore-wing showing its close relationship to Z. 
Thero (Linn.) and Argyraspis, Trim. 
Sardonyx inhabits the dry upland districts of the north and north-east of 
the Cape Colony. In 1864 single examples reached me simultaneously from 
Burghersdorp and Murraysburg, having been captured respectively by Mr, D. R. 
Kannemeyer and Mr. J. J. Muskett. The latter correspondent subsequently 
sent me several fine specimens, from which I described the species at the end 
of 1867. In December of that year Mr. J. P. Mansel Weale sent me a good 
drawing of a 9 taken at Cradock, with the note that the species was " abun- 
dant about Cradock Flats on the ice-plant ; ^ all the specimens varying slightly." 
The only living example I have seen is the $ above mentioned as having been 
captured in Griqualand West ; I met with it at Kolberg on the 6th September 
1872, flying about a rocky hillside.
