90 SOUTH-AFRICAX BUTTERFLIES. 



grouucl-colour, — tlio first not extending below red patch, the other, 

 >Yhich is near liind-margin, extending from near costa to near inner 

 margin; between the two streaks, near costa, a large, nearly circular, 

 black ocellus, yellow-ringed and bipupillate with blue. Hind-icing : 

 outer transverse streak as in fore-wing ; two small ocelli near hind- 

 margin towards anal angle, coloured as in fore-wing, but unipupillate, 

 — the ocellus nearer anal angle smaller than the other. Undeii side. — " 

 Paler ; hind-margin near aj)cx of fore-vnng and whole of hind-iving, 

 more or less closely hatclicd irith -numci'ous short, th'i)i, red-brown liiics. 

 Fore-iving : brick-red patch larger, almost filling discoidal cell ; ocellus 

 and transverse streaks moi*e distinctly marked. Hind-icing : two angu- 

 lated, transverse, reddish-brown streaks, one before, the other about 

 middle ; hind-margin densely hatched with red-brown lines ; only the 

 smaller ocellus visible near anal angle, and that very minute ; another 

 small ocellus between subcostal nervules, close to apex ; sometimes one 

 or two white dots, representing additional ocelli, between the two 

 ocelli mentioned ; in some specimens the whole hind-wing is so densely 

 hatched that the two transverse streaks are inconspicuous. 



A $ specimen from Knysna in my collection has in both fore- 

 wings a minute ocellus adjoining the lower extremity of the ordinary 

 large ocellus ; and there is an additional ocellus in the hind-wings, 

 smaller and more towards costa than the two ordinary ones. 



In a $ example from the same locality, the small ocellus on under- 

 side of hind-wing, near apex, is also distinct on the upper surface of 

 the wing ; while in another $, taken at Forest Hall, near Plettenburg 

 Bay, by Mr. "W. H. Newdigate, the fore-wings bear, in addition to the 

 small ocellus adjoining the ordinary large one, a further small ocellus 

 between first and second median nervules. 



The remarkable distinctness of the yellow rings of all the ocelli is charac- 

 teristic of this Pseudonympha, and the ocelli of the hind- wing are on the 

 upper side unusually large, and withoiit any vestige of fulvous round them. 

 The under side of the hind-wing is quite devoid of the white clouding so 

 characteristic of P. Sahacns, Trim., and P. Trimcnii, Butler; and tlie minuteness 

 of its ocelli and vague definition of its transverse strice recall the same surface 

 in P. vigilam, Trim. 



P. Cas$iiis is very common and of general distribution in Southern Africa, 

 and probably occurs throughout the year, as June and July are the only 

 months during which I liavc not observed it. As usual with the species of 

 this group, the $ s are comparatively seldom met with. Cassius is a butter- 

 fly of very slender structure, and flies more feebly than any other member of 

 this genus I have seen on tlie Aving. 



The paired sexes, taken at D'Urban, Natal, were forwarded to me by 

 Colonel Bowker in the year 1879.
