S. mesoplaga Hmps. (36 g). Forewing brownish white, somewhat darker at the base, the notched white 
interior line behind it. Median line dark, double, notched, filled with white. A large triangular blackish spot 
behind it at the costal margin, white before and behind it at the costal margin, as well as below it. Exterior 
line double, filled with white, excurved as far as vein 6, then notched inward. Submarginal line sharply notched. 
Hindwing pale brown. $ 22 mm. Singapore. 
S. crystallites Meyr. (= polycyma Trnr.) (36 g). Forewing pale greyish lilac and somewhat brownish 
white. Interior and median lines black, double, notched, somewhat outward. Exterior line finer, also double, 
concave above, vein 2 oblique as far as vein 4, then slightly concave above the inner margin, notched. Submar¬ 
ginal line white, notched, edged with brownish. Hindwing white, with a brownish margin. J 22 mm. Queensland. 
S. poliophaea Hmps. (= nolalella Hmps.) (36 f). Forewfing pale brownish grey. Interior line double, 
excurved in the cell, a brown band before it. An indistinct white lima at the cross-vein. Exterior line double, 
filled with white, steeper downward to vein 6 than usual, slightly incurved below vein 4. Darker behind it as 
far as the white notched submarginal line. Hindwing brownish. 22 mm. Assam, Ceylon. 
S. aroa B.-Balc. (36 h). Forewing silvery white. Irregular dark streaks at the base. Behind it a notched 
oblique interior line and a parallel double median line. A dark streak at the cross-vein, and. a short streak from 
the upper cell-angle to the exterior line. The latter double, with 2 black spots at the costal margin, notched, 
rather straight, darker before and behind it at the inner margin. Submarginal line distinct, notched, black. 
Hindwing brownish at the margin. 26 mm. New' Guinea. 
S. avola B.-Balc. (36 f). Forewing yellowish white. The oblique interior line black, double, notched, 
incurved to the inner margin. The double median line the same, with black dots below the costal margin and 
at the cell-angles. The exterior line also double, notched, somewhat outward as far as vein 4, slightly intro- 
angular at vein 1, somewhat darker brownish before it. Submarginal line white, finely edged with black inside, 
brown outside. Hindwing wdiite, broadly brown at the margin, more distinctly defined than usual. 28 mm. 1 $ 
from New Guinea. 
S. kebea B.-Balc. (36 g). Basal half of the forewing wdiite as far as the curved black median line, the 
base itself olive brown. Behind it in the wdiite area there are two rows of black spots obliquely outward and a 
third row only at the costal margin. A white dot at the lower cell-angle. A broad brownish olive band behind 
the median line, bordered outside by a parallel black line. Close behind it a few white streaks and a notched 
wdiite submarginal line in the anterior part. Hindwing similar to that of avola. 30 mm. 1 $ from New Guinea. 
In liehenaria E. Prout the inner-marginal half of the forewfing is pale greyish lilac. The black dentiform spots 
in the basal area are longer, so that a larger black spot is formed at the middle of the median line, a black 
spot before the submarginal line in the submedian fold. Hindwing with a broader, more diffuse marginal shadow. 
The $ is in variably paler. The basal half and the distal margin alw r ays whitish or very little greyish lilac, blackish 
is only sometimes a spot around the reniform macula. 28—35 mm. Ceram, Sumatra. 
S. boeopis Trnr. (36 g) in its marking resembles a small species of Paectes. Forewfing dark greyish brown. 
The lines whitish. The interior one below the costal margin almost to the centre of the wing, then angled and 
sharply inward. Exterior line widely excurved, then incurved to near the middle of the inner margin. Sub- 
marginal line parallel to the margin, steeper from vein 2. Hindwing yellowish, the marginal half smoky brown, 
o 14 mm. Queensland. 
S. abstrusa Trnr. (36 g) is likewise very different. Reddish brown, greyer above the inner margin and 
at the distal margin. A large black spot near the base below the cell, surrounded by the dark interior line in 
a large'bow, below the cell composed of erect scales. Blackish streaks at the middle of the costal margin. Black 
scales at the low r er cell-angle. Exterior line double, filled wfith dark grey, parallel to the margin, in the original 
figure it is grey, filled with dark. Submarginal line of dark spots. Hindwing dark brown. $ 20 mm. Queensland. 
15. Genus : Tliri|>onea Hulst. 
Similar to Giaura and Sarrothripus, but vein 8 of the hindwing branches off near the base of the cell. 
Veins 3 + 4 on a short stalk. Palpi obliquely erect, thin. Forewing rounded, an areole is present. Only 1 species. 
T. muricata Hulst. Forewfing grey. A dark brown stripe at the lower cell-margin at the base, then bent 
into the cell. Median line indistinct, double, the interior branch whitish, the exterior one pale brown, excurved 
in the submedian fold. Reniform macula quite indistinct. The exterior line double, pale brown and whitish, 
incurved behind the cell and in the submedian fold. Submarginal line dark brown, distinct, almost straight, 
slightly incurved at vein 5, edged pale outside. A dark brown spot at the apex. Hindwing lustrous white, brown- 
ish at the margin. $ 25 mm. Philippines. 
16. Genus: Giaura Wkr. 
Palpi thin, highly erect. Antennae of $ finely ciliated. Thorax with a low tuft behind and a small one 
on the first abdominal segment. Forewfing broad, rounded, neuration normal. Veins 3 + 4 of hindwing
