R. deraiota Hmps. (= c-nigrum Hmps. nec L.) (7 d). Forewing dull purplish grey; lines double, dark; 
the inner oblique and waved; the outer lunulate-dentate, the teeth forming points on the veins, excurved above 
middle; subterminal pale and sinuous, defined by the dark terminal area beyond it; orbicular and reniform 
stigmata purplish grey, with brown centres, the orbicular a very wide V, confluent with the purplish grey costal 
area, the cell deep brown black; hindwing brownish, paler towards base; in the $ the thorax and forewing are 
dark purple grey; the hindwing deep brown. Larva pink on dorsum; subdorsal stripe broad, deep black; lateral 
stripes pale yellow, equally broad; a sublateral row of black spots; some narrow redbrown stripes below the 
spiracles; head and legs pink; the ventral area dotted with black; on various low growing plants. Recorded 
only from Ceylon. 
R. flammatra Schiff. (= deleta Koll., basiclavis Walk., bimaculata Mill.) (7 e, a North-Indian $; forth- 
smaller European form cf. Vol. 3, pi. 9g). Forewing grey with a brown or lilac tinge; costa paler towards base; 
a submedian basal streak, the base of cell, and the upper half of tegulae velvety black; orbicular and reniform 
stigmata large, pale grey with white annuli, the cell between them often dark; the claviform faint, outlined 
with black; hindwing brownish grey, the fringe whitish. A large species with elongate wings. Belongs to the 
Palaearctic Fauna, but occurs in N. W. India, and Sikkim. Larva green with pale lateral streaks; feeding on 
various low plants. 
R. renalis Moore (7 e). Forewing dark brown frosted with purplish grey, especially on veins and upper 
stigmata and along the margins; costal streak varying from redbrown in the $ to rufous ochreous in the S'; the 
cell filled up with dark brown, and a dark brown bar on costa before submarginal line at the origin of the brown 
line which precedes it; inner and outer lines brown, double, both ill-defined; a slight brown shade at base of 
submedian fold; fringe concolorous; hindwing fuscous brown. A large species, occurring hr the Punjab and 
Sikkim. 
R. consanguinea Moore (7 e). Forewing redbrown; costal streak ochreous or rufous to outer line; sub- 
basal line followed in submedian fold by a blackish patch with a black point above it in cell; inner and outer 
lines double; the inner oblique, the outer lunulate dentate; subterminal line preceded on costa by a short black 
bar; claviform defined by black at extremity; orbicular and reniform with brown centres outlined with black, 
the reniform with rufous scales in upper part; the cell black; hindwing fuscous brown. Recorded from Simla, 
Dalhousie, Thundiani, Murree, and Dharmsala, all in the Punjab, N. W. India; occurs also in Kashmir and Tibet. 
R. junctura Moore (7 e). Forewing pale ochreous grey, the costal interspaces faintly streaked with 
brown; inner line black, oblique from costa to subcostal vein, then inwardly oblique and angled outwards above 
inner margin, preceded by oblique black streaks in cell and submedian fold; an oblong black brown shading 
including cell and space just below from base to discocellular; claviform fuscous with black edges; orbicular 
oblique, elliptical, ochreous grey; reniform with some reddish fuscous scales in centre and angled inwards 
along median vein; subterminal line preceded by a black bar at costa, and followed by brown terminal shading 
below vein 6; the outer line obscurely marked, lunulate dentate; hindwing pale ochreous grey. Recorded only 
from Dalhousie, K. W. Himalayas. 
R. costalis Moore (= plecta Hmps. part, nec L.) (7 e). Forewing pale grey brown tinged with brick red, 
always paler than plecta L. ; the pale costal streak more diffuse, less conspicuous; its lower edge forked on median' 
vein; a streak from base below cell and the cell itself black brown; claviform long and slender, black edged, usually 
only faintly marked at its extremity with dark scales, often obsolete; orbicular and reniform small, with pale 
annuli and grey centres; lines hardly visible; outer lunulate-dentate; submarginal pale, with the terminal area 
beyond somewhat darker; hindwing white, with black marginal dashes; fringe towards apex rufous. Occurs 
in Sikkim, N. India, and in the Khasia and Naga Hills, Assam. 
R. ignota Swinh. (Vol. 3, pi. 10 a). Differs from costalis in the absence of the black brown cell and 
streak below; the costal pale streak not forked below along median vein; the outer line distinct, and crenulate 
only; orbicular stigma elongate, flattened; hindwing faintly yellowish white. This species occurs in Ceylon 
only. In Vol. 3, p. 44, ignota is quoted as a form of plecta L. but the true plecta does not seem to occur in 
India. 
R. albipennis Btlr. (7 f $ cf. Vol. 3, pi. 10, b). Forewing greyish pink, slightly brown-tinged, wholly 
suffused with olive brown in the$; the subbasal, inner, and outer lines marked by black brown spots on costa; 
inner line finely brown, oblique, excurved above inner margin at middle, preceded at costa, as the subbasal 
line is followed, by a short brown line; outer line fine, brown, outcurved in middle and faintly lunulate; the
