C. tineoides Wkr. (= partitalis Wkr., caffra Wallgr.) (8f). Small and slim, the wings narrow as Uneoidcs. 
in Tinea (from which it has its denomination). Forewing yellowish-grey, only the postmedian line is distinct, 
parallel to the margin, oblique and quite straight. Hindwing whitish, at the apex somewhat darkened. South 
Africa. 
II. Subfamily: Lithosiinae. 
What has been said about the Ethiopian Nolinae, almost entirely also holds good with this subfamily. A great number 
of species belonging hereto are small and insignificant, being mistaken for microlepidoptera and therefore neglected by ignorant 
collectors. Thus we may expect yet a great number of new forms from the central parts of the African Continent, which 
have been but little explored so far, and we are hardly able to-day to supply a tolerably complete classification. On the 
whole, the subfamily is much more homogeneous than might be supposed on surveying the varied shapes, since many differences 
in the shape of the wings or in the neuration are only due to quite secondary modifications often caused by scent-organs. 
Nevertheless it is probable that the Lithosiinae contain the phyletically oldest and most original shapes of the whole large 
Arctiid family and are to be regarded as the direct descendants from the microlepidoptera. 
The Ethiopian Fauna contains still fewer elegant and beautifully coloured forms than the Indian and American Faunae 
do. Some genera being also well represented in the Indian Region, such as Asura and Chionaema, exhibit also in the Ethiopian 
Region more charming aspects, whereas the American Cisthene, Hypoprepia, or the Indian Scaptesyle, Caprimima do not find 
sufficient substitutes in the Ethiopian Fauna; only the genus Anaphosia shows a number of more variegated species. 
As to the habits of the African Lithosiinae, very little has been hitherto known, but nothing makes us infer that there 
is a difference of the Ethiopian Lithosiinae from those of the other faunae. 
1. Genus: Dhig'oa Wkr. 
As to the characterization of this genus cf. Vol. II, p. 51. -— In addition to the statement in Vol. X, 
p. 121, that beside the few palearctic species this genus is Indo-Australian except 1 species from the Cape 
Colony, we note to-day that, in the meantime, a few more Ethiopian species (from West Africa) have become 
known. Also from the Indian Region some more species have been described since Vol. X was published, so 
that the genus, according to the latest catalogue (1922), comprises altogether 35 species. — The Eugoa are 
chiefly found on savanna-like grassy plains, where they rest on blades with their wings closed like a gabled roof. 
E. africana Hmps. (8 f), from Grahamstown (Cape Colony), is uni-coloured light yolk-coloured; across africana. 
the forewing oblique rows of black dots sometimes flown together to streaks; one or two dots also in the cell. 
E. gemina Hmps. (8 f), from the Gold Coast, has an expanse of only 14 mm, being the smallest species gemma. 
of the genus. Eorewing yolk-coloured, in the disc whitish, with a fine double cell-end dot and a transverse 
row of very fine dots in the marginal area. Hindwing yellowish-white. 
E. tropicalis Holl. being unknown to me is doubtfully placed to this genus. Forewing wood-coloured tropiealis. 
grey, towards the base clouded with blackish, the feeble antemedian line is dull and curved, behind it across 
the cell-end a dark transverse shadow in which there is a large white discal dot centred with black. Behind 
it a black, dull, curved transverse line proximally bordered with light grey; an antemarginal angular line being 
dentately produced behind the cell. Hindwing whitish, towards the margin darkened by brick-colour. Expanse 
of wings: 20 mm. From West Africa. 
E. costiplaga Holl. <$. Forewing wood-coloured brown, the darkest at the base; at the centre of the costiplaga. 
costa an almost triangular white spot. A feeble curved submedian line; discal dot indistinct. Body and hindwing 
brick-coloured. Under surface of a light lustrous brick-colour. Expanse of wings: 15 mm. West Africa. — 
This species and the preceding tropicalis being unknown to me, are doubtfully placed to this genus. 
2. Genus: Paremoiiia Hmps. 
Only 2 African, very small species. Proboscis present, but small. Palpi thin, bent upwards before the 
face; $ antenna bipectinate, towards the apex serrate. Forewing oval with a very much curved costal margin 
and hind-margin. The 1st subcostal branch of the forewing rises directly behind the centre of the cell and 
accompanies the costal vein for a short distance. The 2nd subcostal branch rises shortly before the upper cell- 
angle, the 3rd and 4th rising from the upper cell-angle, but terminating into the distal margin, not as in Hemonia 
where they go yet into the costal margin. 
P. argentata Hmps. is light yellow; 3 brown and silvery oblique bands extend near the base of the argentaia. 
forewing, then from the centre of the costa to the tornus, and thirdly before the apex. Hindwing light 
yellow. Expanse 20 mm. Bibianaha on the Gold Coast. 
P. luteicincta Holl. (8 f). Forewing suffused with purple brown, costal margin and distal margin orange; luteicincta. 
in the cell of the forewing a small orange diffuse spot, in front and behind bordered with dark. Very small. 
From Ogowe in West Africa.
