LYCiENIDiE. 209 



narroiu horclcr of fore-wing ashy hrownisJi grey ; rest of fore-wing orange- 

 red. Fore-wing : grey border widening slightly just before and at 

 apex ; a dark fuscous dash at base inferiorly edging median nervure ; 

 black spots in number and arrangement like those of Tliyra, Linn., 

 and allies, viz., three white-centred cellular spots, a transverse, discal, 

 irregular row of six, of which the four upper are white-dotted inte- 

 riorly, and two parallel submarginal rows of seven each, of which the 

 outer row is composed of very small spots indistinctly marking the 

 inner edge of the hind-marginal grey border. Hind-iving : the follow- 

 ing indistinct, hardly sub-metallic, fuscous-edged, greyish spots, viz., 

 three cellular (basal one minute, middle one near third), two supra- 

 cellular (wide apart), two infra-cellular, and six sub-confluent, form- 

 ing an irregular discal row ; a submarginal row of seven thin fuscous 

 lunules, and a marginal spot of seven fuscous sublunulate spots (of 

 which the three lower are well marked) ; between the two rows one 

 of 2^((lo orange lunular marks (the three lower of which are usually well 

 marked) ; on each side of the irregular discal row of spots several more 

 or less indistinct ijalc orange marls. Cilia fuscous, varied between 

 nervules with greyish- white. 



$ Not so glossy ; fore-wing with a suhapical ixdc orange- yellow 

 rounded ixdch. Fore-wing : patch lies between third subcostal and 

 first median nervure, extending from extremity of discoidal cell, and 

 bounded externally by the hind-marginal fuscous band, which is darker 

 than in $, broad, even, and not macular. Hind-wing : apical fuscous 

 marking smaller, less distinct. Under side. — As in ^, but paler and 

 duller throughout. 



(Described from ten $ and three $ specimens.) 



In structure and in the colouring and marking of the under side 

 of the wings this species is plainly referable to the group of which 

 Z. Pierus, Cram., may be considered as the type, but the silvcry-grcy 

 of the nrpper side 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 fore-wings, might 

 almost be taken for a small dull $ Anthoeharis or Teracolus. The 

 under- side 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 marJcs of j^ale orange in the hind-wings nve only found in 

 Z. BarMyi. 



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 lytli August 1873, between Koekfonteiu 

 and the Komaggas Mission Station, tliat the insect was first observed, settling 

 on the small pink flowers of a species of Mesemhryantheinum which car- 

 peted the sides of *t]ie waggon-road. Other localities where it was subsequently 

 seen were on the road from Komaggas to Spectakel ; near Steinbokfontein
