Z. nervosa Wkr. Forewing rusty brown, irregularly speckled with black, with a curved black transverse 
stripe near the base, a black spot near the inner margin before the centre, outside bordered broad and irregularly 
by ash-grey, a pale ash-grey postmedian transverse line not reaching to the costal margin. Veins in the distal 
area pale ash-grey. Hindwing and under surface ash-grey. Costal margins beneath blackish. Expanse: 
19 mm. Congo. 
Z. discophora Hmps. (73 h). Forewing ochreous, densely dusted with brown and blackish. Above the 
inner margin near the base a large pale yellowish spot, surrounded by a jet-black line. Discal area at the inner 
margin more reddish, with a whitish, somewhat sinuate line from the cell to the inner margin, on the cross-vein 
some black dots. Postmedian line indistinct, pale, below the costal margin somewhat excurved, then incurved. 
Between it and the apex a reddish spot with 3 black longitudinal streaks. Apex whitish, with a black marginal 
band projecting towards the base below the reddish spot and ending there. Hindwing suffused with red-brown, 
an indistinct dark line, from the costal margin below the centre to the margin, a somewhat brownish marginal 
line. Under surface grey, dusted brown and blackish. Rhodesia.. In the habitus somewhat similar to 7j. ploetzi. 
Z. recurvata Hmps. Body red-brown, slightly mixed with grey. Fore wing red. brown, mixed with 
grey and dusted with dark, interior half of the basal area chocolate-brown. A feeble, straight, whitish shadow 
from the costal margin beyond the centre to vein 2, continued in a white line which is upturned to the cell 
and inwards to the inner margin before the centre. An indistinct dark incurved line extends from the apex to 
the margin at vein 4, outside bordered with whitish. Hindwing lustrous red-brown, dusted with grey and 
blackish. Expanse: 22 mm. Gold Coast. 
Z. bilineata sp. n. (73 h). Similar to discophora , but the area surrounded by the black curved line near 
the base is not pale yellowish, but chocolate brown. The white line from the cell-end to the inner margin and 
the following postmedian line extend quite narrow next to each other and are hardly divergent at the place 
where they surround the red spot. The red-brown subapical spot exhibits no black streaks. Veins beyond the 
post median line whiiish. Hindwing blackish-grey, under surface the same, in places speckled with yellowish 
and with yellowish veins. $ type from Bagamoyo in the Berlin State Museum. 
Z. unilineata sp. n. (73 h). The white postmedian line is absent, and there is only, one straight white 
line from the cell-end to the inner margin. In the forewing the black curved line is near the base, the enclosed 
area blackish, the whole space between this line and the white line rust-brown, a rust-brown apical spot lacks 
the black streaks, the veins are white. Hindwing and under surface dark grey, slightly mixed with yellow. 
Separated from nervosa by its more intense rust-brown marking and the absence of the black spot before the 
centre. Cameroon. <3 type from Kribi in the Berlin State Museum. 
Z. ploetzi Schs. c9 Clem. (73 h). Somewhat similar to discophora , the white postmedian band to the 
costal margin is absent. Black marking more distinct. Togo to Spanish Guinea, Southern Sudan. 
23. Genus: ftusica Wkr. 
Chiefly distributed in the Indo-Australian region. Antennae in the strongly bipectinate to %, then 
bare, in conf usa from Africa to the tips, gradually decreasing. Hind tibiae with 2 pair of spurs. In the hindwing 
vein 8 with the cross-vein to the anterior edge of the cell, 6 + 7 stalked. In the forewing 10 from the same place 
with the stalked veins 7 -9, in confusa 10 and 7 from the same place with the stalk of 8 + 9. 
S. confusa Wkr. (73 h). Sulphur-coloured, hindwing somewhat more ochreous, head, thorax beneath, 
base and costal margin of forewing as well as body beneath somewhat ochreous. Sierra Leone. 
S. molybdea Hmps. Antennae of <$ with one row of short pinnae. Body yellowish, with a reddish tint 
and a slight silvery grey reflection, tegulae at the ends darker. Forewing red-brown, with an intense silvery 
grey lustre, particularly in the median area, where the silvery dusting shows an oblique distal edge which rises 
from the costal margin near the apex. At the cross-vein a feeble dark dot, an indistinct oblique, sinuate, dark 
line from the cell-angle to the inner margin, a feeble brown subterminal line, excurved above and below the 
centre. Hindwing pale red-brown, with a greyish gloss. Expanse: 38 —44 mm. Sierra Leone, Gold Coast. 
(This species having remained unknown to me may belong to Ctenolita.) 
S. pyrocausta Hmps. (73 h). Forewing purple red; costal margin ochreous, dusted with black; a blackish, 
slightly curved antemedian transverse band from the cell to the inner margin. At the cross-vein 2 black dots, 
behind them a greyish-white postmedian line which is outside broadly bordered with blackish, except at the 
costal margin, and which has inside, above the inner margin, a narrow black border. Hindwing ochreous white, 
anal margin somewhat reddish, binder surface ochreous, with a reddish tint. Hindwing in the $ dark red-brown. 
Congo, Mashonaland, Transvaal. (Unknown to me.) 
24. Genus: Thosea Wkr. 
Chiefly distributed in the Indo-Australian region. Antennae in the with long double pectinations 
as far as the ends. Palpi moderately long, distal joints short. Hind tibiae with 2 pair of spurs. In tile hindwing 
the cross-vein between vein 8 and the anterior edge of the cel 1 , 6 + 7 stalked, in the forewing 10 from the same 
place with the stalked 7—9.
