RHYACIA. By W. Warren. 
grey; the costal area brown beyond middle; lines and markings as in tincta Leech, but the insect is smaller and 
duller; the hindwing shows a large dark cellspot. Sikkim and the Punjab. 
cervina. R. cervina Moore (8 a). Forewing purple grey sprinkled with purplish black, most densely in median 
area, which contains a large diffuse patch of the same colour on costa before outer line; inner and outer lines 
black, double, filled in with the ground colour; the inner uniformly curved from costa to vein 1, then angled 
outwards; the outer oblique inwards parallel to termen, biconcave, with a slight outward bend on vein 4; sub¬ 
marginal line purple black, ill-defined, thicker at costa and angled outwards on vein 7; fringe purple grey with 
a faint rufous tinge; claviform stigma diffuse, blackish; orbicular and reniform with dark grey centres and pur¬ 
ple grey annuli defined by dark, the reniform partly lost in the dark patch; hindwing greenish fuscous, the 
fringe brickred. Allied to cerastioides Moore and tincta Leech, but larger and darker. Recorded from Sikkim 
and the frontier of Nepal. 
dispalata. R. dispalata Sivinh. (8 a). This and the three next species are closely allied to the well known palae- 
arctic putrisL. ; except the last, triseriata Moore, they are all smaller; dispalata and venalis Moore are distinguished 
at once by the cell between the stigmata being blackish. In dispalata the ochreous ground colour is slightly suffused 
with pale brown, and sometimes shows fulvous streaks between the veins towards termen; the costal streak 
and the centres of stigmata are brown mixed with grey scales; the inner line is brown, strongly dentate out¬ 
wards between the veins and angled inwards on them; the outer line marked by a double series of dark vein 
points, the inner preceded by a brown median shade; a brown dentate shade on termen on both folds, the apex 
of the upper one reaching outer line; hindwing pale grey in both sexes. Mainly a South Indian species, recorded 
from Poona and Ivhandalla, Bombay, and from Belgaum, Madras; but a pair from the Khasia Hills in Tring 
Museum appears to belong. 
venalis. R. venalis Moore ( ? = sicca Guen.) (8 a). Distinguished from the preceding by the whole cell of forewdng 
being black and produced as two conjoined black streaks beyond reniform to termen; the inner line'is more 
curved below costa than dentate; costal streak browner and broader; the dark lines between veins in the basal 
area more prominent; stigmata both smaller and clearer, the orbicular round, the reniform strongly indented 
externally; hindwing pale ochreous in both sexes, except towards costa and apex and faintly along termen, 
where it is grey tinged; a slight cell dot. Restricted apparently to N. W. India, being recorded from Simla, 
Dalhousie, Dharmsala, and the Kangra Valley, Punjab, and from Sind. Guenee’s sicca may be the same species, 
but the locality of his type was unknown. 
mundipen- R. mursdipennis Warr. (8 a). Forewing pale clear ochreous, only the costal streak and the basal area 
nis g re y p ro -Yvn; lines scarcely visible, but the inner line appears to be toothed outwardly above and below vein 1; 
claviform stigma with a dark dot at its apex; orbicular a flattened oval, the centre blackish in a wide ochreous 
ring outlined with pale brown; reniform an oblique figure of 8, filled up with black in an ochreous ring of which 
only the inner half is wide and edged with brown; slight black brown streaks at termen on veins 6, 5 and 2, and 
slighter ones on vein 1 and the submedian fold; those on 6, 5 connected by faint brown streaks with the reni¬ 
form ; fringe ochreous scantily mottled with brown; hindwing pale ochreous with slight brown terminal dashes; 
fringe ochreous; under side ochreous, with the costal half of forewing and costal edge in hindwing dull brownish; 
head, palpi, and tegulae pale ochreous tinged with rather bright fulvous; thorax and patagia dark brown; ab¬ 
domen dark grey . Described from a single $ from Bandong, Java. 
triseriata. R. triseriata Moore (8 b). Larger and less neatly marked than putris L.; the lines and shades all well- 
marked across wing; otherwise the stigmata and terminal blotches resemble those of mundipennis. Recorded 
from Sikkim and the Punjab; also from the Khasia and Naga Hills, Assam. 
ravida. R. ravida Schiff. ( = obscura Brahm.) (Vol. 3, pi. 10 k). Forewing greyish fuscous; costal area reddish, 
a black dash on submedian fold before inner line; cell sometimes blackish; stigmata dark-edged; orbicular; 
very variable in shape, round or flattened, sometimes produced basewards; hindwing dull whitish, the veins 
obducta. and termen grey; — ab. obducta Esp. has the whole forewing grey brown, including the costa; — ab. bigramma 
bigramma. Esp. is like it, but with the cell black between the stigmata; — ab. rufa Tutt is the reverse of the two preceding, 
austera' Nie whole wing being reddish like the costa, while ab. austera Esp. (= crassa Haw.), also reddish brown through- 
suffusa. out. has the cell black; -— ab. suffusa Tutt is blackish fuscous with the lines and stigmata more or less obscured. 
Larva ochreous brown, with pale dorsal line, and a subdorsal row of oblique yellowish bars edged above with 
fuscous; feeds on a variety of low plants. Found in the Punjab, N. W. India. 
deniiculata. R. denticulata Warr. (Vol. 3, pi. 11 i). Forewing purplish brown with some fuscous suffusion and black 
irroration; costa paler to postmedian line; a slight black streak from base below cell; inner and outer lines double, 
filled in with rufous ochreous; the inner angled outwards and faint below costa, oblique and sinuous below 
the cell; the outer oblique to vein 6, then strongly dentate to vein 2, and outwardly angled on vein 1; subter¬ 
minal line defined by diffuse dentate black marks on its inner side; a row of black points along termen; clavi- 
^ form stigma large, obscurely black-edgecl; orbicular and reniform large with black outlines; the former pale,
