closing cell is a black streak usually merged with basal 

 clouding. Cilia fuscous mixed with white : in hind-wing 

 mingled with red. UNDER-SIDE. Costa and apex of fore-wing 

 and whole of hind-wing pale creamy-ferruginous ; no basal 

 clouding. Fore-wing : two cellular spots and first spot of 

 transverse row silver-centred ; a third black dot in cell, and 

 another (silver-centred) on costa beyond cell ; beneath central 

 spot of cell a good-sized rounded spot below submediaii 

 nervure ; close and parallel to hind-margin a row of fuscous 

 spots, indistinct near costa. Hind-wing : often almost spotless ; 

 a pale glistening line closing cell ; near it, towards inner- 

 margin, a pale dot ; a submarginal row of pale dots, sometimes- 

 replaced by a faint reddish line : transverse row sometimes 

 represented by spots barely distinguishable from ground- 

 colour except by their fusco-ferruginous outlines. 



From its allied congeners, Z. Zeuxo and Z. Chrysaor, mibi, this species is 

 at once distinguished by its blue-glistening basal patches; while its entire 

 outline of wings and plainly-tinted under-surface preclude its being mistaken 

 for the angulated Z. Thysbe, Linn. In the two species first-named, also, the 

 ground colour is metallic, strikingly so in Chrysaor.

I first met with this very beautiful Zeritis, interesting from its relations 

 to the three species just mentioned, on the sand flats near the coast of 

 False Bay, a few miles from Wynberg, in October, 1861. I have since 

 taken it in other parts of the Flats, usually settling on spaces of white sand, 

 or on the low plants that fringe such arid spots. I only once took a specimen, 

 at a little distance from the Flats, on a hill-side at Wynberg.
