hind-wing continuous, tliongli narrow, to anal angle. On the under side the 

 silvery litura? are paler and thicker than usual. A $ from the same locality 

 differs similarly from \Yestern individuals of that sex (except as regards the 

 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. 



This Zeritis is the most highly ornamented of its genus, and perhaps excels 

 in beauty all other South- African Lyccenid(je. 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 Avhere it occurs ; it settles frequently on the ground or on low plants, 

 and is partial to the fleshy leaves of the larger species of Mesemhryanthemum. 

 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 Avith than the females. I have not taken it near Cape Town, 

 where it is very scarce ; but it inhabits Kalk Bay, 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 Robertson in January 1876.

^ Pale-orange, with an irregular disced roio of quaelrate hlacl^ spots ; 

 very hroadly shot with silvery-blue. Fore-wing: blue extends over the whole 

 surface from base to extremity of discoidal cell and along inner margin to 

 beyond middle, usually almost obliterating terminal disco-cellular black 

 spot and sometimes partly the lower three spots of discal row, — in the latter 

 case meeting liiud-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 Tin/she. 

 Hind-wing : discal row of spots as in Thysbc, but smaller, the fourth,
