black-ringed discal dot. Fringes dark brown, at the base lighter brown. Hindwing with the same ground¬ 
colour as the forewing and with a lighter median transverse band forming a continuation of the light transverse 
band of the forewing. Wings beneath light yellowish, at the base, the apex of the forewing, and at the costal 
margin of the hindwing suffused with dark brown. Expanse of wings: 65 mm. Ogowe, Cameroon. ■—- nigri- nigritarsis. 
tarsis Strd. (33 c). The marks of this form are to be seen from the figure. The whitish brightening at the costal 
margin of the forewing seems to be much more extensive than in spargata. Gabun; Cameroon. 
Ph. vulpecula Strd. is very similar to Ph. spargata, but it differs in the submarginal transverse row vulpecula. 
of black punctiform spots and the presence of a median transverse line in the hindwing; in the forewing the 
submarginal dots are less distinct, particularly because they are not proximad bordered with light as in spargata ; 
beneath both wings exhibit a submarginal row of black punctiform spots which are just as distinct as those 
on the hindwing above; the median transverse line of the hindwing beneath is almost straight. Both wings 
above brownish-red, beneath somewhat lighter, fawn-coloured, above with a fine black discal transverse line 
and a submarginal row of black dots. Expanse of wings: 70 mm. Belgian Congo. 
Ph. obscura n. sp. (31 c). A somewhat different species. Eyes hairy. Vein 9 of forewing into obscura. 
the discal margin. Anterior tibiae unarmed. Palpi below densely long-haired with a knob-shaped terminal 
joint, not projecting beyond the' frons. Antennae of A with long pinnae. The whole insect is dark grey with 
black markings. Body above darker, beneath lighter grey. Forewing above dark grey, in the marginal portion 
somewhat lighter grey; the first transverse line is almost erect, angular, touching the black discal dot; the 
second transverse line is dentate, distally bent, almost parallel with the margin, double; the sub marginal spots 
are almost separate, forming an irregular transverse row. Hindwing above just as dark as fore wing, the discal 
and submarginal bands are coherent, bent. Both wings beneath lighter, feebly reddish-grey, without submarginal 
dots, but with a joint, very distinct, bent black discal transverse line. Expanse of wings: 44 mm. South Rhodesia. 
12. Genus: Olyra Wallgr. 
Very closely allied to the preceding genus, but separated by the densely haired eyes. Palpi projecting 
beyond the frons, in the A beneath with long and dense hair, with a knob-shaped terminal joint, in the $ longer, 
more slender, and less densely haired with an oblong terminal joint. Antennae of A with long, in the $ with 
short pinnae. Anterior tibiae unarmed. Hind tibiae only with terminal spurs. Wings in the A short and 
broad, in the $ more elongate, at the margin entire or almost entire with very long fringes. Fore wing above 
invariably behind the centre with a discal transverse line and a coherent or striated submarginal line. To what 
was said about the neuration in the table of genera, we need only to add that the veins 4 and 5 of the 
hindwing proceed forked from the posterior angle of the discal cell. 
The species form two easily discernible groups. 
First Group of Species. 
The proximal (subbasal) transverse line of the forewing is absent or very indistinct; the distal one is straight (A ) or 
feebly curved ($), erect (A) or slanting (2). The submarginal dots are entirely or almost entirely united forming a bent dark 
brown submarginal line parallel with the margin; this line approaches or even touches the discal line at the posterior margin. 
Discal dot white with a dark ring. Hindwing above with a dark, often nebulous, rarely quite absent discal band; rarely 
also with a submarginal band. 
0. reducta Walk. (£ = caffra Wallgr.) (31 c). Forewing above in the basal portion dark red-brown, reducta. 
in the marginal area outside of the discal line always more or less light, fawn-coloured, and with a curved 
submarginal line. Hindwing above lighter than the fore wing and generally with a distinct red-brown median 
band. South Africa to Mashona Land and Nyassa Land. — sublineata Walk. (A = distanti Dew. ; $ = niris sublineata. 
Drc.) (31 d) is the northern form hardly different from reducta ; it is somewhat smaller, and the sub marginal 
line of the forewing is somewhat less bent. Nigeria. Congo District. — pallida Auriv. is a light very small form, pallida. 
Forewing above in the basal half fawn-coloured, in the marginal portion whitish; hindwing in the A whitish 
fawn-coloured, in the $ white without any marking. To the north of Lake Edward. 
Second Group of Species. 
Porewing above with a distinctly prominent, subbasal, quite straight transverse line and a similar discal line; both 
the transverse lines are vertical to the anal margin and bordered with yellowish-white. Discal dot dark brown. The submarginal 
line is composed of indistinct dark brown transverse streaks which are distally sharply bordered by whitish. Palpi of $ projecting 
beak-shaped. 
0. rectilineata Auriv. (31 d). Both wings above dark brown; forewing above with three transverse rectilineata. 
lines, hindwing with one that is sometimes indistinct. Fore wing beneath much lighter, yellowish, at the margin 
broadly red-brown. Hindwing beneath red-brown with two centrally deeply angular light transverse lines. 
Gaza Land and Mashona Land. A unknown.
