from base in and below cell, thence obliquely to apex; a dark streak from base below cell, and an oblique 
streak above inner margin before middle; veins white, defined by fine brown lines, the outer half of median 
vein and veins 4, 3 more prominently; lines expressed by black points; an oblique pale fascia from apex to 
vein 2, the area beyond it browner; hindwing whitish tinged with grey brown, particularly on veins and to¬ 
wards termen; the fringe whitish. The Punjab, Sikkim, Bhutan; northwards through Tibet and Kashmir to China 
and Japan. 
H. micacea Hmps. (12 b). Forewing purplish whitish; the veins white defined by fine dark streaks; 
the terminal intervals with dark streaks; the median vein in outer half and veins 4, 3 more conspicuously 
white; an oblique dark streak above inner margin before middle; inner and outer lines shown by vein points 
only; an oblique pale streak from apex to vein 2, the area beyond it darker; hindwing semihyaline white; veins 
and terminal area brownish; ab. intensa ab. nov. from Ceylon has the thorax and forewing more suffused with 
redbrown, especially in and below cell and thence obliquely to apex. A smaller species, occurring only in South 
India; Mahableshwar, Bombay; the Nilgiri Hills, Madras; Ceylon. 
PL ossicolor Warr. (12 b). Forew r ing bone colour with slight dark dusting and a very faint tinge 
of rufous terminally; inner line marked by dark vein points, oblique to submedian fold, then bent in¬ 
wards; outer line lunulate dentate, appearing double; reniform stigma paler, with a dark dot at lower end and 
slight grey cloud beyond; the end of the median vein whitish; a slight oblique grey shade from apex; a 
row of black terminal dots; fringe concolorous; hindwing dark grey, the costal third bone colour; cellspot and 
veins darker; in the $ a dark curved outer line followed by a dark border; fringe whitish. Described from a 
pair from Darjiling, Sikkim: allied to flavistigma Brem. and inornata Leech, the ioreving beneath having the 
cell fuscous.

Differs from Hyphilare Hbn. mainly by the absence of the black lateral tufts of hair at base of abdomen.

S. albicosta Moore (= pallidicosta Hmps.) (12 c). Forewing fulvous, suffused and streaked with rufous 
grey; costal edge white; the veins finely grey; a white or grey dot at lower angle of cell; stigmata pale ful¬ 
vous, with darker centres; lines lunulate dentate; hindwing rufous grey, paler towards costa. The Punjab, 
Sikkim, and Assam in N. India; also in Java, Borneo, and Flores; in the palaearctic region it is found in 
W. China; the form coming from Ceylon, subsp. brevipennis subsp. nov. (12c), is a shorter-winged insect, with 
less oblique termen and squarer apex; the forewings darker in ground colour, Avith the markings in conse¬ 
quence partly obscured; the veins towards termen hardly pale; the white dot at loAver end of reniform whiter 
and clearer, the median vein not being pale; hindwing blacker fuscous, the fringe rufous; another form, 
— subsp. saturata subsp. nov. — (12 b, c), occurring in the Malay peninsula and in Java, is of the same size 
and shape as typical albicosta. but suffused throughout with ferruginous or chocolate brown, so that all the 
markings are overpowered; the paler stigmata can just be discerned and the white dot is present; in the $ 
from Java the suffusion is rufous: in the £ from Gunong Ijau, Malacca it is dark chocolate; the hindwing, 
the dorsum, and the underside of both wings being dark fuscous, "while in the forewing above the costal 
edge is as dark as the rest of the -wing. -<p : V - [ > J 
S. fraterna Moore (12 c). Fore wing dark fulvous brown; the costal edge whitish; the veins finely 
whitish; transverse striae dull yellow, long and slender; no distinct white point at lower angle of cell, nor 
outer line of points; the reniform stigma linear, yellow; hindwing pale purplish red, with a faint fuscous tinge 
except towards inner margin. Dharmsala, the Punjab. 
S. vitellina Hbn. (Vol. 3, pi. 23 i). Forewing pale yellowish ochreous, typically strongly flushed with 
rufous; the veins finely rufous; lines fine, more or less angulated, the inner and outer approximated on inner 
margin; stigmata indistinct; the orbicular slight, often obsolete; reniform rufous, with a dark spot in lower 
end; hindwing ochreous white, greyer in $, the veins often fuscous; the pale, less highly coloured, specimens, 
Avith whiter hindwings, — ab. pallida Warr. (Vol. 3, pi. 23 i) which seem to be comparatively rare in Avestern 
Europe are the usual form in Syria and Turkestan. The species, almost exclusively palaearctic, is reported 
from Ivulu and Sultanpur in the Punjab. The larva is pale flesh colour; the dorsal and subdorsal lines white, 
with darker edges; spiracles black on a pale yellow lateral line; head broAvn Avith black markings; on grasses. 
S. nigrilinea Leech (= fasciata Moore praeocc.) (<J 12 d; $ Vol. 3 pi. 23 k). ForeAving greyish ochreous, 
faintly flesh-coloured; veins pale, lined with broAvn; vein 4 white; a black streak beloAV cell from base; a black 
brown streak from base through cell, widening to apex; lower ends of orbicular and reniform stigmata indicated 
by black marks with pale edges; hindwing dirty whitish, towards termen more smoky grey. Recorded from
