S. diagramma Beth.-Baker (12 li). Forewing whitish slightly tinged with violaceous; costa and inner diagramma. 
margin somewhat dusted with black; terminal interspaces streaked with purple-brown, the whitish veins defi¬ 
ned by lines of the same colour; a purple brown shade below median vein and a black streak in base of 
submedian fold; median nervure and vein 4 more prominently white; a black point at lower angle of cell; 
an outer row of black points on veins, met at vein 4 by a pale oblique streak from apex with a brown trian¬ 
gular shade below it on termen; hindwing brownish ochreous, paler towards base; a row of black terminal 
points; the abdomen of is clothed throughout with rough shaggy hair. Recorded only from New Guinea. 
S. bifasciata Moore (12 i). Forewing rufous; the costal area pale ochreous to middle, the inner margin bifascia/a. 
nearly to anal angle; median vein and veins beyond cell whitish; a black point at lower angle of cell; an 
outer row of black points on veins, joined by a slight dark triangular shade from below apex; fringe pink; 
hindwing ochreous whitish, tinged with fuscous towards termen; fringe pinkish at base. Recorded only from 
Dharmsala, in the Punjab, N. W. India. 
S. roseilinea Walk. (= simillima Walk.) (12 i). Forewing whitish ochreous tinged with vinous red, roseilinea. 
the costal area black-dusted; veins white, defined by purple brown streaks; the terminal intervals also streaked

middle; a brown shade below median nerAUire, and black point in lower angle of cell; an outer row of black 
dots on veins; a pale oblique streak from apex, dark edged above and with a broAvn triangular shade beloAV 
it from termen; hindwing simply whitish ochreous, without darker shading. Travancore and Pirmaad, Madras;

S. polemusa Swinh. (12 i, k). Forewing narrow, Avhite; both costal and inner marginal areas with polemusa. 
slight dark irroration; a yelloAV shade on inner marginal area and beloAV median vein to end of cell, whence it 
turns obliquely to apex; veins white defined by fine broAVn streaks, the median vein more conspicuously white, 
slightly hooked at end of cell, in which there is a black dot; a black streak along submedian fold to origin of 
vein 2; an outer roAV of black vein points; black terminal dots; fringe intersected with white; hindwing 
pure white; the $ is decidedly paler than the <$. Recorded only from Poona, Bombay. 
S. moorei Swinh. (= abdominalis Moore nec Walk.) (12i). ForeAving flesh colour or straAv yelloAv; veins moorei. 
whitish edged Avith fine brown streaks; the intervals also streaked Avith brown; a brown streak beloAV median 
vein; a black dot on submedian fold and two, obliquely placed, on veins 4 and 2 represent the inner and 
outer lines respectively; a triangular dark terminal shade below apex; hindwing ochreous white, suffused 
with fuscous except along costa, most strongly toAVards termen and on veins. A Avidely distributed species, 
occurring in the Punjab, Bengal, Sikkim, Assam, the Nilgiris, Ceylon, Formosa, the Malay Peninsula, N. Luzon, 
St. Aignan, N. Guinea, and Queensland. 
S. lineatipes Moore (= percisa Moore) (12 k). Forewing smooth brownish ochreous, sparsely black lineatipes.

olive brown streak from base below median vein to beyond cell, and a broAvn shade above vein 4 widening to 
apex; a small black dot in loAver angle of cell; an indistinct outer toav of black dots on veins; hindwing whitish, 
suffused with brownish grey. A north Indian insect, occurring at Sultanpur, Kulu, Simla, and Dharmsala in 
the Punjab, and in the Khasia Hills, Assam. The species is also found in the Goorais Valley, Kashmir. In the

stinct pale streak from apex; terminal black dots; hindwing semihyaline white; some black terminal points
