SOUTH-AFRICAX BUTTERFLIES. 
(between Spectakel and Abbevlakte) ; and at Oograbies (about fifteen miles 
inland from Port JSTolloth). It is very conspicuons on the wing, the pale upper 
side (of the ^ especially) flashing like silver in the sunshine. Though settling 
frequently on flowers and on the ground, it is by no means so easy of capture 
as most of its allies, being unusually w^ary of approach and swift in flight. 
While in motion it has much the appearance of a large pale Lyccena, such as 
L. Corydon, Scop., or L. Asteris, Godt. ; but when it has settled, its under-side 
colouring renders it as inconspicuous as its near congeners in repose usually 
are. In the elevated hilly country Z. Barldyi seemed to be rather widely dis- 
persed, but was local in its haunts, being numerous in a few spots only, on 
the sunny slopes of hills. In the flat sandy country near the coast no 
examples were to be found.

appressed hair ; eyes large, globose, naked ; palpi inferior, exceedingly 
small and short, — basal and second joints clothed beneath with long 
scales of unequal length, — terminal joint minute, short, obtuse;

Thorax very short and slender, thinly scaled. Foi^e-ioings large, 
long ; hind-margin convex, entire ; costa moderately arched ; costal 
nervure ending about middle of costa ; subcostal nervure five-branched, 
— first and second nervules given off, not far from each other, some 
distance before extremity of discoidal cell, — third about midway be- 
tween cell and apex, — fourth about midway between third and apex, 
and terminating at apex ; discoidal cell unusually long ; first disco- 
cellular nervule long, lying longitudinally, — second much shorter, 
oblique, — third the longest, curved, meeting first median nervule at a 
decided angle a good way beyond latter's origin. Hind-ivings elongate ;
