2 20 SOUTII-AFEICAN BUTTERFLIES. 



of the wings generally also wants tlie whitish irroration always preva- 

 lent in Amal'osa, 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- 

 teristic, as they (especially the fore-wings) have a much less curved 

 costa and more produced apical region. 



This very interesting addition to the genus UUrhania was discovered by 

 M. L. Peringuey, of Cape Town, on the Hex River Mountain in the district 

 of Worcester, Cape Colony, on the 2d January 1882. On that occasion lie 

 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 5 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 difliculty 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-ochrcous ; fore-ivings with hlacJcish Jjordcring. Fore- 

 wing : 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- 

 wing shining leadcn-grey, varied with reddish-ochreo7is 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
