of the wings generally also wants the whitish irroration always preva- 
lent in AmaJcosa, so that the whitish markings show plainly out on the 
dark ground-colour. On the upper surface the discal row of spots is 
in the fore-wings more sharply incurved, and in the hind-wings not 
incurved and more irregular. The shape of the wings is also charac- 
teristicj as they (especially the fore-wings) have a much less curved 
costa and more produced apical region. 
This very interesting addition to the genus D' Urhania was discovered by 
M. L. P^ringuey, of Cape Town, on the Hex River Mountain in the district 
of Worcester, Cape Colony, on the 2d January 1882. On that occasion he 
secured only one of the two specimens observed; but in December 1884 he 
was fortunate enough to capture ten more examples in the same locality, one 
of them being the $ above described. The butterfly frequented a steep ravine, 
and all the examples observed settled on the sides or face of the bare rocks in 
the full sunshine. When at rest, they could with difficulty be distinguished, 
so assimilated is their under surface to the colour of the rock ; and on the wing 
they were very inconspicuous, flying in a slow, wavering manner, and suddenly 
dropping to settle.

$ Pale orangc-ochreous ; fore-ioings loitJi hlacldsh horcleriiig. Fore- 
luing : border rather wide from base along costa, abruptly interrupted 
on costal edge beyond middle, but thence forming a broad apical 
border, which rapidly narrows along hind-margin to a point at anal 
angle ; border marked on costal edge by four sub- quadrate spots of the 
ground-colour, and emitting at the point of abrupt interruption a 
broad ray downward as far as second median nervule ; before this ray, 
and united to the border, a blackish marking defines extremity of dis- 
coidal cell ; in some examples a similar blackish spot about middle 
of cell, and a smaller more indistinct one in cell nearer base. Hind- 
wing : spotless ; a narrow, ill-defined, reddish-fuscous, hind-marginal 
edging. Cilia fuscous, with paler dull-whitish interruptions (more 
visible in fore-wing). Under side. — Hind-wing and markings of fore- 
tving shining leaden-grey, varied ivith reddish-oclireous spots. Fore-wing : 
ground-colour towards inner margin paler than on upper side, but 
darker near costa and hind-margin ; markings similar in position to 
those of upper side ; mark at extremity of cell broader, and preceded 
by two similar cellular marks ; ray from costal border before middle
