50. Genus: Phorma Karsch. 
Antennae of q in the basal halves with long double pectinations, then bare. Palpi projecting beyond 
the frontal tuft, last joint slightly drooping. In the forewing 7 rises from the same place with 8 +9, 10 remote 
from it. In the hindwing 6 + 7 stalked, 8 near the base anastomosing with the cell. 
Ph. pepon Karsch (75 b). Body red-brown, in front and partly on the abdomen fiery red. Forewing pepon. 
brown, basal area more dark red, with an oblique almost straight line in the centre, and divergent with 
it a submarginal line from the costal margin to the termen above the tornus, both black, outside slightly 
bordered with lilac grey. Hindwing dark brown. West and East Africa. 
51. Genus: fllliocemi Karsch. 
Male antennae bipectinate, suddenly decreasing from the centre to the tips. Palpi similar as in Phorma. 
Costal margin of forewing quite straight or even concave. In the hindwing 6+7 stalked, 8 shortly anastomoses 
with the cell. In the forewing 7 stalked with 10, these stalked with the stalk of 8 + 9. To this genus probably 
also belong some of the species mentioned as Thosca. 
0. syrtis Schs. <£• Clem. (75 b) (= ganale Pagenst.). Forewing brown, basal area mostly darker, distal syrtis.

so in the §. In the whole of West Africa as far as Natal, Southern Sudan. The species varies somewhat. 
Forelegs with a silvery spot. 
0. convergens sp. n. (75 b). Similar to syrtis, but the exterior transverse line is not parallel to the convergens. 
margin, but posteriorly convergent with it, the interior transverse line is outside bordered by a lighter colour. 
Eastern Transvaal to East Africa. <+ $ types from the White River in the Berlin State Museum, also from 
Mohorro. 
0. thanatos sp. n. (75 b). The length of the male antennal pectinations gradually decreases to the thanatos. 
tips. Wood-coloured grey, mixed with ochreous and blackish. Forewing grey, dusted somewhat darker, the 
slightly darker basal area undulately defined, especially below the cell deeply indented, the exterior transverse 
line near the distal margin into which it terminates in the lower third. Hindwing and under surface light grey, 
dusted with a darker grey. Male type from Kibwezi in the Berlin State Museum (Coll. Oberthur). Uganda. 
0. micacea Btlr. (75 b). Forewing reddish silvery grey, with an oblique median line and convergent micacea. 
with it a subterminal line becoming indistinct towards the inner margin, both lines red. Hindwing, more 
intensely the forewing beneath, and part of thorax greyish-red. Madagascar. 
52. Genus: Niphadoleipis Karsch. 
Antennae also in the $ plain, palpi moderately long, slightly upturned, hind tibiae with 2 pair of spurs. 
In the hindwing 6+7 stalked, 8 free, in the forewing 7—9 stalked, veins 10 and 11 anteriorly very convex. 
Habitually similar species are also to be found among the Narosa. The genus may coincide with Gavara. 
N. nivata Karsch (75 c). White, thorax green, in front brownish. Forewing white, with a pale olive nivata. 
green straight antemedian transverse band, another one extending across the cross-vein, where it bifurcates 
towards the inner margin, the exterior branch bifurcating once more at the tornus, a third from the costal 
margin before the apex to the distal margin along which it extends for some distance. At the posterior angle 
of the cell and at the termen below the apex one jet-black dot each, single black scales on the surface of the 
wings. Hindwing white. Togo. 
N. lactea Pagenst. (75 c). Body white, abdomen yellowish. Forewing white, with 4 almost parallel, lactca. 
undulating brownish-yellow transverse lines and a black central dot, some black marginal dots at the apex. 
Fringe white, speckled with brownish. Hindwing white, in the distal portion shaded with brown, at the margin 
below the apex black dots. Expanse: 15—20 mm. Ganale, North-East Africa, German East Africa. 
N. sinistra sp. n. (75 c). Similar to lactea, the basal transverse stripe is absent or only distinct at the sinistra.

margin in the + Hindwing of $ at the margin not grey. Female type from Daressalam (leg. A. Retjss) in the 
Berlin State Museum, also from Mhonda. 
N. soluta Karsch (75 c). Forewing white, the basal third dusted with olive green, bordered by a notched soluta. 
line, also the distal third broad green, at the distal margin intermixed with lilac-grey, so that only a median 
band being somewhat darkened and expanded at the inner margin remains white. Hindwing white, more 
or less dusted with greyish ochre. Togo. 
N. elegans Wichgr. Forewing white, inside slightly tinted yellowish, a metallic olive green transverse elegans. 
band, 2 mm broad, mixed with black, outside of it another one being shorter and less regular, and connected 
with the apex at vein 6, so that two semicircular white areas are defined at the distal margin. At the margin 
in areas 7 and 8 two black dots. Hindwing white, around the apex three oblong black marginal spots. Expanse; 
23 mm. German East Africa. (Unknown to me.)
