narroiu horcler of fore-iving asJiy hroionish grey ; rest of forc-unng orange- 
red. Fore-iuing : 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 Thyra^ 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-wing : 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 pcde orange lunular marks (the three lower of which are usually well 
marked) ; on each sida of the irregular discal row of spots several more 
or less indistinct ])ale orange inarlis. Cilia fuscous, varied between 
nervules with greyish-white. 
$ Not so glossy ; fore-wing with a sidjapical j)ale orange-yellovj 
rounded iiatcli. 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 J, 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. Pierii.s, Cram., may be considered as the type, but the silvery-grey 
of the U2)}Kr 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 $ Anthocharis or Teracolus, The 
under- side markings combine to some extent the characters of Z. 
Thyra^ Linn., and Z. Pierm, Cram., but the brownish-grey inclines 
much more to ashy than in either of the species named, and the lumdar 
and scattered marks of ])cde orange in the hind-tvings are only found in 
Z. Barldyi. 
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 Koekfontein 
and the Komaggas Mission Station, that the insect was first observed, settling 
on the small pink flowers of a species of Mesemhryanthemum which car- 
peted the sides of^llie waggon-road. Other localities where it was subsequently 
seen were on the road from Komaggas to Spectakel ; near Steinbokfontein
