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 once took a specimen at a little distance from 
the Flats, on a hillside at Wynberg, and subsequently took five specimens at 
Kalk Bay, in the Cape District, about the steep hillside above the village. 
I also captured a single $ on the summit of the hill behind Simon's Town. 
Mr. Peringuey, in 1882 and 1883, met with two or three examples (one an 
unusually large $ ) at a considerable elevation in the Worcester District, viz., 
at Hex Kiver Mountain and Touws Eiver. 
It does not appear to be numerous in any locality, occurring singly or in 
pairs.

blue usually completely covering basal half of wing, extending obliquely 
from costa at end of cell nearly to anal angle ; cellular spot and discal

border from end of cell to apex, marked with three white dashes between 
nervules ; joining it a hind-marginal border of variable width, some- 
times entire up to cilia, but usually with an external lunulate orange 
edging. Hind-wing : blue not extending beyond discal row of spots, 
which are arranged as in Pyroeis ; costal and hind-marginal border very 
much narrower than in fore-wing, its latter portion often reduced to a 
row of dots at ends of nervules ; anal-angular projection long and rather 
acute. Cilia white, interrupted with blackish mixed with orange on
