cular a small black spot; at lower angle of cell a black point; hindwing ochreous white suffused with 
brown, darker on veins and towards termen. A very distinct species of wide occurrence; recorded from 
Sikkim in the North, Bombay and Madras in the South of India; Ceylon; Burma; the Andaman Islands; 
Singapore; Borneo; Manilla in the Philippines; the Loo-choo Islands. 
S. semiusta Hmps. (13 d). Forewing ochreous slightly irrorated with fuscous; a purplish brown 
suffusion in and below cell, expanding terminally to near apex and tornus; an angled dark mark in 
cell representing inner line; outer line a series of dark points on veins; a triangular fuscous shade on ter¬ 
men below apex; an oval ochreous discoidal spot; hindwing whitish at base and along inner margin, 
otherwise fuscous; the fringe white. The type, a from the Nilgiri Hills, Madras.

S. modesta Moore (13 d). Forewing pale ochreous sprinkled with fuscous; inner line vertical, 
dentate, with darker spots on the veins; outer line lunulate dentate, the teeth forming black points on 
the veins, indented slightly on the folds; an oblique dark shade from termen below apex with a flesh- 
coloured tinge before and below it; a slight black point at lower angle of cell and fuscous suffusion 
beyond; hindwing ochreous white, with fuscous suffusion except at costa; terminal black points as on 
forewing; fringe ochreous white; underside of hindwing with black cellspot preceded by a dark streak 
on median vein showing through above; both wings with dark dentate outer line. A North Indian in¬ 
sect, occurring in Sikkim and the Khasia Hills, Assam. 
S. metaphaea Hmps. (13d). Forewing pale ochreous with a rufous flush, the terminal area with 
fuscous irroration; inner line absent, except for a dark speck on submedian fold; outer indistinct, lunu¬ 
late dentate, the teeth dark on the veins, indented on both folds; an oblique dark shade from termen 
below apex; hindwing wholly dark fuscous; the fringe ochreous; underside of forewing wholly fuscous 
except at margins; a small dark spot on costa beyond middle; hindwing with the area below cell fus¬ 
cous to near termen; a dark cellspot preceded by a dark streak on median vein as in modesta. The type, 
a <$, from the Palni Hills, Madras. 
S. hypophaea Hmps. (13 d). Forewing greyish with blackish irroration and a slight rufous tinge; 
inner line a series of points on veins oblique to submedian fold, then bent inwards; outer line a 
series of dark points, oblique below vein 4, indented beyond cell; end of median vein and lower half 
of discocellular whitish, with a black point in lower angle of cell and a more or less developed black 
mark beyond; hinclwing wholly fuscous, except costa; fringe ochreous white. Ceylon. 
S. rubrisecta Hmps. (13 d). Forewing ochreous with slight black speckling; the inner marginal 
half tinged with pale purplish brown; median vein rufous; a black point in lower angle of cell; a 
double row of black points on veins represents outer line; a rufous streak from termen below apex 
oblique to vein 4; hindwing wholly fuscous; the fringe ochreous white. The type, a from Bhutan. 
S. albivitta Hmps. (13 e). Forewing bright rufous; an indistinct blackish streak below base of 
cell; inner line sinuous and oblique from costa to submedian fold, where it is angled outwards and again 
inwards on vein 1; outer line dentate, oblique below vein 4 and indented on submedian fold; traces of 
a sub terminal line from termen below apex, angled inwards beyond cell; orbicular and reniform stig¬ 
mata small, partly defined by black, the former elliptical, the latter with a black point in lower angle 
of cell and white streak below it at end of median vein; hindwing fuscous, the fringe white. Described 
from a $ only from the Nilgiri Hills. The terminal segment of palpi is somewhat long and slender. 
S. percussa Btlr. (= howra Moore, basilinea Swinh.). Forewing pale ochreous, flushed with brown 
and sparsely irrorated with black; the veins whitish defined by fine brown streaks, the terminal inter¬ 
vals with brown streaks; median vein defined by fuscous above and below; a black streak on submedian 
fold to origin of vein 2; a black point in lower angle of cell; outer line denoted by a series of black 
points; hindwing white. Sikkim and Bengal in India; Burma; Java; and Formosa, whence the type of 
percussa ; Moore’s howra from India; Swinhoe’s basilinea from Burma. 
S. cruegeri Btlr. (= praeclara Swinh.) (13d, e). Forewing pale ochreous; some slight fuscous 
irroration along costa and inner margin; costal edge white; median vein broadly wdiite, with a brown 
streak below; veins 2, 3, 4, 5 and the ends of 6, 7 streaked with white, 4 most prominently; some 
brown streaks in the interspaces; an oblique dark shade from termen below apex; hindwing semi¬ 
hyaline white; the terminal area tinged with brown. An Australian species; recorded from Brisbane and 
Gayndah, Queensland, and from Roebuck River, Sherlock River, Cossack, and Roebourne, W. Australia. 
S. aspersa Snell. (= homopterana Swinh.). Forewing ochreous, the cell, inner margin, and ter¬ 
minal area rufous-tinged; veins whitish with rufous streaks on eacli side and in the intervals; median vein 
more prominently white, expanding into a small spot at end followed by a small fuscous patch; in¬ 
ner line marked only by two obliquely placed black points, on submedian vein beneath origin of vein
