2IO SOUTH- AFRICAN BUTTERFLIES. 



(between Spectakel and. Abbevlakte) ; and at Oograbies (about fifteen miles 

 inland, from Port ISTolloth). It is very conspicuous 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 wary of approach and swift in flight. 

 While in motion it has much the appearance of a large pale Lyccena, such as 

 L. Corijdon, 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.

Imago. — Head small, densely scaled in front, vertex with closely- 

 appressed hair ; eijcs large, globose, naked ; ^;o^pi inferior, exceedingly 

 small and short, — basal and second joints clothed beneath with long 

 scales of unequal length, — terminal joint minute, short, obtuse ; 

 antenna3 short, rather thick, with abruptly-formed elongate-ovate club, 

 obtuse at tip. 



Thorax very short and slender, thinly scaled. Fore-wings 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 neiwule 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-wings elongate ; 

 hind-margin very convex, entire ; precostal nervure distinct ; costal 

 nervure short, ending not far beyond middle ; first subcostal nervule 

 emitted considerably before extremity of cell and ending at apex ; 

 upper disco- cellular nervule short, oblique, — lower twice as long as 

 upper, much curved, meeting first median nervule as in fore-wing ; 

 submedian nervure extending to anal angle ; internal nervure very 

 long, ending not far before anal angle ; discoidal cell rather long and
