hind-wing continuous, though narrow, to anal angle. On the under side the 
J silvery liturse are paler and thicker than usual. A 9 from the same locality 
' differs similarly from Western individuals of that sex (except as regards the 
I blue), and has the blackish border of both wings — though less distinctly in 
hind-wing — pierced exteriorly by acute white denticulations adjoining the white 
parts of the cilia. 
I This Zeritis is the most highly ornamented of its genus, and perhaps excels 
1 in beauty all other South-African Lyccenidce. On the wing its general hue 
seems to be silvery, but when basking in the sunshine with half-opened wings 
it looks like some brilliantly burnished jewel. Though local in its haunts, 
frequenting sandy hillsides and the dunes on the sea-coast, it is usually rather 
numerous wdiere it occurs ; it settles frequently on the ground or on low plants, 
and is partial to the fleshy leaves of the larger species of Mesembryanthemum. 
I have found it at various dates from the middle of September to the end of 
April, but it appears most numerously in October and January. The males are 
much oftener met with than the females. I have not taken it near Cape Town, 
where it is very scarce ; but it inhabits Kalk Day, and is occasionally almost 
abundant on the hills at the back of Simon's Bay. At Mossel Bay, where I 
first saw the species, it was very numerous on 20th September 1858, and I 
took many near Kobertson in January 1876.

J Pale-orange, loith an irregular discal roio of quadrate hlack sj^ots ; 
very broadly shot loith silvery-blue. Fore-wing: blue extends over the whole 
surface from base to extremity of discoiclal cell and along inner margin to 
beyond middle, usually almost obliterating terminal disco-cellular black

case meeting hind-marginal blackish border at posterior angle; this border 
moderately wide, even throughout, usually marked externally with more 
or less defined orange lunules ; spots of discal row arranged as in Thysbe. 
Hind-wing: discal row of spots as in Thysbe, but smaller, the fourth,
