minor. 
P. ignorata sp. n. (73 a). Darker than brunnescens, the dark costal-marginal spot before the apex 
much broader, the dark basal spot is continued in a narrow curved line around the costal-marginal spot 
to the apex. Ground-colour wood-brown, markings darker red-brown. Hindwing grey. Under surface yellowish 
to grey. Togo, New Cameroon. Male type from Togo in the Berlin State Museum (Coll. Oberthur). 
P. secunda Strd. (73 a). Still darker than ignorata, margin of forewing straighter. Forewing reddish- 
brown, markings as in ignorata, not very distinct, costal-marginal spot defined by a greyish-white line. The 
curved stripe to the apex is nearer to the margin than in the preceding species. Hindwing and under surface 
deep black. Body above black, beneath yellowish, thorax above dark red-brown. Spanish Guinea, Cameroon. 
P. sudanensis sp. n. (73 a). Larger and with broader wings than the preceding species, margin of forewing 
very convex. Ground-colour of forewing light red-brown, markings distinct, dark red-brown. The triangular 
spot at the costal margin not surrounded by light, the curved line to the apex from the basal spot to the apex 
is situate nearer to the margin than in ignorata. Hindwing brownish grey. Under surface yellowish grey, forewing 
towards the base darkened. Southern Sudan. + $ types from Tembura in the Berlin State Museum (Coll. 
Oberthur), in December. 
3. Genus: ItSiypieira Holl. 
Antennae of C in the basal halves with long double pinnae, in the terminal halves quite bare like those 
of the $. Hind tibiae with 2 pair of spurs. In the forewing veins 4 and 5 are distantly separated, 7 forked with 
the stalk of 8 + 9, 10 remote and straight. In the hindwing veins 6 and 7 from the same place, 8 before the 
middle of the cell connected with it by an oblique cross-vein, the cell below y 2 of the wing. Apex of forewing 
obtuse and much rounded off. 
R. sordida Holl. (= apiceplagiata Beth.-B.) (73 b). Forewing brownish-grey, Avith a circular dark grey 
spot in the apex, being more distinct and blacker towards the base, an indistinct dentate line before and 
sometimes behind the centre, and a black fine dot at the cell-end. Hindwing somewhat greyer than forewing. 
Under surface somewhat lighter, abdomen yellowish-brown. Wings of $ somewhat broader than those of <$. 
Togo, Cameroon. 
4. Genus: Cossuna Wkr. 
Antennae of $ either uniformly pectinated to the tips ( polana ) or in the basaTportions with long pinnae, 
in the distal halves with short ones, in the $ very shortly dentate. Hind tibiae with 2 pair of spurs. Veins of 
forewing similar as in the preceding genus, in the hindwing 6 and 7 stalked or from the same place, between 8 
and the cell a cross-vein far before the centre, behind it 8 far in front with drawing from the cell. 
C. rugosa Wkr. (73 b). Forewing ochreous brown, towards the inner margin yellow, this light portion 
of the wing traversed by a straight dark oblique streak directed upon a very conspicuous yellow cell-end spot. 
Hindwing varying from yellowish to blackish. Thorax above yellow, abdomen brownish. From French Guinea 
to Cameroon, in Gabun, Southern Sudan, and Uganda. 
C. marginata Holl. Antennae of G as in the following polana. Forewing olive brown, with a conspi¬ 
cuous yellow discal dot. Hindwing paler, at the base and anal margin ochreous, both wings with a marginal 
row of yellow spots. Beneath the yellow spots larger. Thorax above like the forewing. Abdomen ochreous. 
East Africa, Uganda. 
C. polana Drc. (73 b). Forewing sulphur-coloured, veins and a curved line from the cross-vein to the 
inner margin violettish brown. The forewing is often predominantly brown, with a yellow spot at the base 
of the inner margin and at the cell-end. Hindwing yellow, with darker veins. Fast Africa. 
5. Genus: Scotiiiochroa Btlr. 
Neuration the same as in the preceding genus, antennae with longer and more uniform pectinations. 
Palpi very long, falcate, second joint very long, obliquely bent up, third joint half the length of the second. 
The genus having remained unknown to me is said to be allied to Zinara. 
Sc. inconsequens Btlr. Forewing reddish chocolate-brown, strewn with lustrous scales of a grey leather- 
colour; a D-shaped spot at the cell-end, connected with a slanting irregular one from the costal margin before 
the apex to the inner margin. At its upper end it is narrowest and inwardly curved. The spot and band are 
outside whitish-brown and inside of grey leather-colour, towards the base defined by black shadows and outside 
by a black line; the band is inside zigzag-shaped, outside undulated. It is followed by a similar transverse spot 
which, however, is not yellow inside. Hindwing pale silken reddish, in a certain light somewhat greenish, the 
anal margin and the base of the fringe brown or auburn. Expanse: 28 mm. Nyassaland, February. 
Sc. minor Hmps. (73 c). Body light and dark brown mixed with yellow. Forewing light brown, strewn 
with dark brown and rough silvery scales; an indistinct dark spot below the origin of vein 2. Postmedian area 
whitish ochreous with an indistinct band of dark and silvery scales, at the lower cell-angle almost spot-like,
