a little less long than in squanmlata, which may possibly, however, prove to be a race of the same species. 
Kenya Colony (loc. typ.) and Tanganyika Territory. 
S. squamulata Warr. is less small and somewhat more ochreous than macrostyla but otherwise very squoumhi- 
similar; presubterminal band of forewing more equally developed throughout, whereas in tmcrostyla it is gene- 
rally posterior only, or chiefly. Leg-structure as in plesioscotia. Natal. 
S. hispidata Warr., known only from the type $, is recognizable by its glossy whitegrey ground-colour, hiapidatn. 
coarse dark-grey irroration and especially by the unusually proximal position of the lines and the very 
sinuous subterminal, which between the raclials expands greatly on its proximal side. Lines rather thick, 
sinuous, the median — as in sinuilinea — very near the antemedian, the postmedian not far beyond the 
cell-dot. Underside glossy, almost without markings. Expands 18 mm. Libollo, Angola. 
S. sinuilinea Prout (8 i). Less glossy than hispidata, generally browner, with the markings more reddish sinuUinca. 
brown, at least in the type. Hindtibia of ^ rather long, with strong pencils, which partly conceal the short 
but not minute tarsus. Forewing with median line approximated to antemedian, nearly parallel with it. 
Hindwing moderately rounded. Transvaal (type), Portuguese East Africa, Orange Free State and Southern 
Rhodesia. 
S. subtorrida Prout (8 i). Near torrida but somewhat larger, antemedian line of forewing more aciitely suMorrlda. 
angled, subterminal shades rather strong, distal margin of hindwing less protuberant, under siirface well 
marked, showing large cell-dots and moderately strong postmedian line. British Somaliland, only the tjq)e 
$ known. 
S. torrida Warr. (8i), also known only from a single $, is smaller and less heavily irrorated than torrida. 
jumilinea, the forewing with more acute apex. Otherwise similar. Cunene, Angola. 
S. prionodonta Prord (8 i). Larger and relatively longer-winged than/ttmr7mea, paler and with scarcely priomdon- 
any black irroration. The principal lines more acutely angulated, the median more distally placed, faint, 
brownish, on the forewing arising from a black costal spot, very acutely angled oirtward at the 1 st radial, 
then curving inward to the base of the medians; black dots on fringe intense. Underside very faintly 
marked, excepting a postmedian costal dot and the fringe-dots. Thies, Senegambia (type); Kete Kratje, 
W. Togoland, 1 $. 
S. fumilinea Wourr. (7 i). Antennal ciliation of long, in fascicles; hindtarsus of extremely short, fumilinm. 
tibia shorter and less tufted than in sinuilinea. Variable, especially in colour, often more reddish than in that 
species; further distinguishable therefrom by its still more sinuous and more distally placed median line 
and its more elongate hindwing (in the middle more strongly convex). Underside in both species glossy 
and almost iinmarked. Transvaal to the Cape, the type from Natal. —- f. confracta Prout (7 k) presents a super- confracta. 
ficially very different appearance on account of the pale groiind-colour and great reduction of the dark 
irroration. Described from Cape Colony, known also in Natal. 
S. tristega Prout (7 k). Variable is size (14—22 mm) as well as the warmth of the ground-colour, trlstcga. 
which, however, always shows a decided tinge of reddish or cinnamon-brown. The dark shading between 
the postmedian and subterminal lines recalls that of the Palaearctic trigeminata Haw., though each pair of 
“twin"’ spots is generally more confluent. Face black. antenna with the joints projecting, bearing rather 
long fascicles of cilia. hindleg less short than in jumilinea, the tibia heavily scaled above and with a 
hair-pencil from the femoro-tibial joint, the tarsus quite short (about y^^). Underside glossy, weakly marked. 
Madagascar: Diego Suarez. 
S. controversata Prout ( 8 i). antennal cilia about as long as width of shaft, hindtibia rather controversa- 
short, with hair-pencil, tarsias about i/o tibia. Pale fleshy grey, costal margin of forewing reddish ochreoiis; 
further differs from the preceding group in its larger size and the extreme weakness of the submarginal shades. 
Salisbury, Southern Rhodesia. 
S. leucorrheuma Prout (8 i). Palpus minute. Tongue wanting (?). Antenna rather slender, joints scar- leucorrlmi- 
cely projecting, ciliation long (about 2 ). Hindleg slender, short, the tibia and tarsus together very little longer 
than the femur. Wing whitish, slightly glossy, mostly suffused with mouse-grey, in places with some coarse 
darker irroration; a narrow band remaining white betweeen median and postmedian lines, the rest of median 
area intermediate in whiteness; median line thick; srdAerminal line almost as sinuous as in jumilinea, but less 
thickened. Hindwing with termen strongly convex, the sinuosities rather more pronounced than on forewing; 
stalking of 2 nd subcostal short. Underside similarly but still more sharply marked. Cape Colony: Oude- 
bosch, 1 in coll. Soiith African Museum. 
S. nasifera Prout (8i) founded on a/)$ from Warmberg, Transvaal, is another long-winged species, nasifcra. 
a good deal smaller than controversata, without the ochreous costal margin and best recognized by the
