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 u'hole of hind-ioing pale creamy -ferruginous ; no basal 

 clouding. Fore-toing : 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 submedian 

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

 spots, indistinct near costa. Hind-ioing : 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. Chri/saor, milii, ibis species is 

 at once distinguished by its blue-glistening basal patches; wl)iic its entire 

 outline of wings smd plainly-tinted under-surl'ace preclude its being mistakea 

 for the angulated Z. Thi/sbe, 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 Wyiiberg, 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 sucii arid spots. I only once took a specimen 

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