some new species of South African Li/c(Bnid(B. 339 



between 3rd sub-costal and 1st median nervnre, extending 

 from extremity of discoidal cell, and bounded externally 

 hj the hind-marginal fuscous band (which is darker than 

 in $ , broad, even and not macular). Underside. — As 

 in $ , but paler and duller throughout. 



(Described from ten $ and three $ specimens.) 

 In structure and in the colouring and marking of the 

 underside of the wings this species is plainly referable to 

 the group of which Z. Pierus, Cram., may be considered 

 as the type, but the silvery-grey of the upperside is a most 

 striking distinctive character, quite unique in the genus. 

 This peculiar colour is so pale that at first sight the 

 expanded ? , with its orange apical patch in the forewings, 

 might almost be taken for a small, duU $ A?ithocharis or 

 Callosune. The underside markings combine to some 

 extent the characters of Z. Thyra, Linn., and Z. Pierus, 

 Cram., but the brownish-grey inclines much more to ashy 

 than in either of the species named, and the lunular and 

 scattered marks of pale orange in the hindwings are only 

 found in Z. Barklyi. 



I have named this butterfly after His Excellency Sir 

 Henry Barkly, the governor of the Cape Colony, to whose 

 kindness I owe the opportunity of visiting Namaqualand, 

 and who first called my attention to the species as some- 

 thing unusual. It was on the 17th August, 1873, between 

 Kockfontein and the Komaggas Mission Station, that the 

 insect was first observed, settling on the small pink flowers 

 of a species of Mesembryanthemum which carpeted the 

 sides of the waggon-road. Other localities where it was 

 subsequently seen were on the road from Komaggas to 

 Spectakel ; near Steinbokfontein (between Spectakcl and 

 Abbevlakte) ; and at Oograbies (about 15 miles inland 

 from Port Nolloth). It is very conspicuous on the wing, 

 the pale upperside (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 appear- 

 ance of a large, pale Lyccena, such as L. Cory don. Scop., 

 or L. Asteris, Godt., but Avhen it has settled, its underside 

 colouring renders it as inconspicuous as its near congeners 

 in repose usually are. In the elevated, hilly country 

 Z. Barklyi seemed to be rather widely dispersed, but was 

 local in its haunts, being numerous in a few spots only —
