90 SOUTH-AFEICAN BUTTERFLIES. | 
ground-colour, — the first not extending below red patcli, tlie other, 
which is near hind-margin, extending from near costa to near inner I 
margin; between the two streaks, near costa, a large, nearly circular, 1 
black ocellus, yellow-ringed and bipupillate with blue. Hind-wing : 
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. Under side. — . 
Paler ; hind-margin near ajjcx of fore- wing and ivhole of hind-wing, 
more or less closely hatched with numerous short, thin, red-hrotun lines. ^ 
Fore-vjing : brick-red patch larger, almost filling discoidal cell ; ocellus | 
and transverse streaks more distinctly marked. Hind-ioing : two angu- 
lated, transverse, reddish-brown streaks, one before, the other about . 
middle ; hind-margin densely hatched with red-brown lines ; only the i| 
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 i 
ocelli mentioned ; in some specimens the whole hind- wing is so densely 
hatched that the two transverse streaks are inconspicuous. 
A J 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 Pseudonym]p]ia, and the ocelli of the hind-wing are on the 
upper side unusually large, and without any vestige of fulvous round them. 
The under side of the hind-wing is quite devoid of the white clouding so 
characteristic of P. Sabacus, Trim., and P. Trimenii, Butler; and the minuteness 
of its ocelli and vague definition of its transverse strise recall the same surface 
in P. vigilans, Trim. 
P. Cassius 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 have 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 the wing. 
The paired sexes, taken at D'Urban, Natal, were forwarded to me by 
Colonel Bowker in the year 1879.
