fined outer line; orbicular stigma round and large, not oblique and narrow; terminal area blackish, defining 
the subterminal line, which is also preceded by a brown shade containing wedgeshaped marks; veins of 
terminal area redbrown; hindwing dull whitish with the veins dark, and a well defined dark fuscous 
terminal border beyond a dark outer line; in the $ the hind wing is more uniformly fuscous, as in 
sodalis. Sikkim; Bhutan; Khasia Hills. Assam. The form basalis Moore from the Punjab has the outer area basalis. 
less distinctly yellow. 
P. boopis Hmps. (16 b). Forewing dull wood brown; the lines and markings slightly darker; boo pis. 
the terminal area beyond subterminal line dark brown; inner line double, excurved between the veins; 
outer line lunulate dentate, the teeth marked light and dark on veins; subterminal line pale, preceded 
by obscure brown marks and at costa by a dark patch; median shade bent at middle, below plain 
and waved; claviform stigma dark brown; orbicular of the ground colour, edged with darker, flattened; 
reniform with inner and lower edge dark brown, the inner third brown, the middle black and white speck¬ 
led; the outer edge formed by a white dot at top and two at bottom, with a white dash between 
them; fringe brown; hindwing pale brownish fuscous with dark cell spot and outer line. Resembles the 
two preceding species, but the ground colour is brown instead of ochreous. Khasia Hills, Assam and 
the Punjab. 
P. fasciata Leech (16 b). Forewing bright redbrown; the antemeclian and postmedian areas bluish fasciata. 
white, except towards costa; claviform black; orbicular round, with dark centre and outline; the reni¬ 
form with some bluish white mixed with the dark centre; the inner and outer dentate lines and the 
median shade black and distinct; submarginal line very indistinct, but forming a bluish white apical 
patch; hindwing pale fuscous, with dark cellspot and outer line. Described from W. China, but occurs 
also in Assam, Sikkim, the Punjab and Tibet. Superficially the species is much like P. struvei Ragusa 
from Sicily. 
P. askoldis Oberth (= nivalis Btlr.) (16 b). Thorax chalk-white; sometimes also the abdomen; aslcoldis. 
forewing chalk white; markings redbrown; viz., the costal streak, the upper half of median area to 
submedian fold, the base above median vein, and two dark spots at termen on the folds; claviform stigma 
black, with a black streak from it above to outer line, continued to termen; orbicular stigma elliptical, 
with white centre ringed first with brown and then with rufous orange; reniform white, black-edged 
internally; submarginal line white with brownish grey shades on each side; hinclwing of $ whitish ochreous, 
of $ fuscous. Another palaearctic species, which also occurs in the Khasia Hills, Assam. 
P. funerea Hein. (Bd. 3, Taf. 39f). Forewing blackish redbrown, the redder tints confined to the funerea. 
two folds and the submarginal line; the inner and outer lines very obscure; a thick black streak above inner 
margin near base; stigmata somewhat paler than ground colour, edged with black; outer edge of reniform 
dotted with white and with a longer yellowish or white mark at its middle, often preceded by some 
white scaling; from the reniform to outer line two thick black streaks run, with sometimes a third 
above them; these two streaks are characteristic; submarginal line reddish, preceded by black teeth, 
the terminal area blacker; hindwing dark fuscous, with rufous tinged paler fringe; — the form both from 
China and Japan — subsp. oriens Warr. (Bd. 3, Taf. 39f), —• is larger, not so dark, so that the transverse oriens. 
lines and markings are more visible; the costal area and the veins are dusted with white scales; and the 
wing is always without the two black streaks beyond the reniform stigma, which characterise the type; — a se¬ 
cond form, from Japan only, subsp. brunneafa Warr. (Bd. 3, Taf. 39g), is of the same size as the type, brunnecita. 
but liver brown in colour, with only the terminal area black except the apex, which is paler, less 
sprinkled with white, and also without the black dashes beyond the reniform; all the forms alike have the 
orbicular stigma of the narrow, elongate shape that characterises the group. Larva almost indistingui¬ 
shable from that of rurea. This palaearctic species is recorded from the Punjab, N. India. 
P. formosensis Hmps. (16 b). Forewing in basal and median areas and along costa deep redbrown; formosensis. 
the inner margin grey; the space between inner and subbasal lines greyish white; that between outer 
line and subterminal ochreous, the apex also ochreous; lines blackish filled up with whitish; the inner 
inbent on subcostal vein, then obliquely excurved; the outer lunulate dentate, the teeth marked as 
black and white points on the veins, which are dark; subterminal whitish, preceded below vein 2 by 
a black streak; a terminal series of small black lunules; claviform stigma large, defined by black; 
orbicular oblique and elliptical; reniform filled in with white in outer half, and with a black centre; 
liindwing fuscous grey. Formosa.
