SOUTH-AFEICAN BUTTERFLIES. 
tarsus of about equal length ; tibia a little shorter, ending in a blunt ' 
spur, and with a few bristles superiorly ; tarsus with four joints, shortly I 
spinose beneath and at extremity. Middle and hind legs of moderate 
length, rather slender ; femur scaly ; tibiae with a few spines beneath, 
and with terminal spurs long ; tarsi spinose inferiorly. 
Abdomen short, in 6 verj slender. 
The butterflies of this genus are very nearly allied to Erehia — a 
group well known from its great development in the Alpine tracts 
of Central Europe. They are, however, separable by the following , 
characters, viz., (i) their much less robust structure generally, espe- 
cially as regards the shorter and more slender abdomen, which in 
the $ is not thickened at the end ; (2) the less density of their hairy 
clothing, especially on the head, palpi, and thorax; (3) their shorter 
and more slender antenna ; (4) the rise of the second subcostal nervule 
of their fore- wings far beyond, instead of before or just about, the 
extremity of the discoidal cell; (5) the constantly swollen base of the ' 
costal nervure of their fore-wings ; and (6) the greater width (and in 
the fore- wings less length) of their discoidal cells. 
The Pseudonymplim known are butterflies of small or moderate size, 
very much resembling some of the species of ^r^Sm. Unlike the latter, 
however, they are all of one pattern of colouring and marking. This 
consists of a ground of paler or darker dull-brown, with a larger or 
smaller discal patch of fulvous in the fore-wings and usually in the 
hind-wings. Except in rare instances of aberrant individuals, the fore- 
wings bear only a single bipupillate ocellus not far from the apex, 
while the hind-wings (in some cases devoid of markings) usually pre- 
sent two submarginal unipupillate ocelli. The underside is generally i 
mottled or freckled, and paler than the upper side ; the fore- wings are f 
of the same pattern as above, but often with a larger field of fulvous ; 
while the hind-wings bear from two to six submarginal ocelli, and two 1 
transverse streaks (often enclosing a darker or paler space) rather before 
middle, as well as often a third streak beyond the ocelli. Of this ; 
pattern the transverse streaks and the ocelli on the under side of the 
hind-wings vary most in the difierent species, both characters being 
almost obsolete in P. Hyperlius and P. irrorata. The eleven species 
recognised by me as inhabiting South- Africa seem, with the exception j 
of P. Natalii (Boisd.), which extends beyond the Southern Tropic, to ! 
be peculiar to that region, but a twelfth species, closely allied to P. 
Natalii^ occurs in Southern Tropical Africa, so that the genus may 
perhaps have a wider range than has hitherto been assigned to it. The 
species most generally distributed in South- Africa are P. Casswis (Godt.), 
P. Sahacus (Trim.), and P. vigilans (Trim.), but the first-named seems 
nowhere so abundant as the others. P. Narycia^ Wlgrn., and P. Neita^ \ 
Wlgrn., are widely spread in Eastern South Africa, but cannot be 
termed common; and the remaining species appear to be very local 
and scarce. As the country becomes better explored, especially in its
