RHYAGIA. By W. Warren. 
Sect. I. Antennae of bipectinate with moderate branches. 
ochracea. R. ochracea Walk. (6 i). Porewing dull grey tinged with lilac in basal half and with rufous in terminal, 
rarely altogether rufous; lines obscurely marked; inner vertical below subcostal vein, where it is angled; outer lu- 
nulate dentate, the teeth forming a double row of black points on veins with pale points between; subterminal 
line pale, hardly waved; terminal area beyond it sometimes darker; claviform stigma marked only by a dark 
dot at its end; orbicular round, pale, with brown outline; reniform with dark centre and pale annulus, the lower 
frontalis, lobe darkest; hindwing fuscous grey; fringe pale grey tinged with rufous; the form frontalis Moore (6 i) has the 
forewings more purplish grey, with the terminal area dark, a dark form of the which in all cases is less rufous 
perrufa. than the <$; the wholly rufous form. ab. perrufa ab. nov. (6 i) is confined to the <$. The species is smaller than 
the allied forms, which have been mixed up with it, and occurs only in Ceylon. 
stictica. R. stictica Pouj. (= varia Swinh., ochracea Htrips, part, nec Walk.). In Vol. 3, pi. 8 a we gave a figure 
of the c?; here we give the $ (6 k). $ Forewing dingy grey-brown, when fresh with a reddish suffusion; stigmata 
concolorous with the ground, partially pale- and black-edged; the lower half of reniform blackish; lines all 
double, filled up with paler, the outer line followed by black vein dots; submarginal line pale with dark edges, 
sublunulate; fringe rufous grey with a bright pale line at base; hindwing fuscous grey; the $ has the head 
and thorax, and the forewing dark brownish fuscous, the upper half of reniform stigma showing paler, and the 
hindwing fuscous towards termen. Pou jade’s type was from Mou-pin, W. China; Swinhoe’s varia from Umballa 
in the Punjab, where it appears fairly common and extends into Kashmir. 
niptistricja. R. ruptistriga Walk. (6 k). Forewing rufous brown grey, always brighter than stictica Pouj. ; the lines 
and markings clearer and more defined; the stigmata, even the claviform, filled in with pale grey; the lower 
lobe of reniform only slightly darker; orbicular stigma preceded by a black brown triangular mark; the space 
between the stigmata blackbrown below cell fold, the black running up along the edges of stigmata to sub¬ 
costal vein; $ much darker, uniform red brown or dark brown, without the fuscous suffusion visible in the $ 
of stictica-, the reniform stigma concolorous. Originally described from Ceylon, but occurs like the last species 
in N. W. India, also in Sikkim and the Khasia Hills, Assam. 
olivasccns. R. olivascens Hmps. (6 k). Forewing pale brownish fawn colour; the cell and base of submedian interval 
olive brown; stigmata of the paler ground colour, without annuli or darker outline; lines very indistinct; the 
outer indicated by a slight row of dark vein dots; terminal area rather deeper, beyond an indistinctly lunulate 
subterminal line; hindwing and fringes dull grey. A Sikkim species, also found on the frontier of Nepal and at Kulu 
in N. W. India. 
redo. R. veda Howes. Forewing silvery grey with slight red suffusion; orbicular and reniform stigmata in¬ 
complete, outlined in brown and united together; a series of slightly darker markings between the veins; lines 
obsolete, except an indistinct interrupted inner line; hindwing grey, darker towards termen. Described from 
a single <$ from Nelson, New Zealand. 
Sect. II. Antennae of $ bipectinate to just beyond middle; the pectinations short and stiff. 
ypsilon. R. ypsilon Pott. (= suffusa Schiff., idonea Cram., spinula Esp., spiniferus Haw., robusta Blanch., bipars 
Walk., frivola Wlngrn., aureolum Schaus) (6 k). Forewing narrow, grey brown, suffused in parts with smoky 
fuscous; claviform stigma small, black-edged; orbicular oval; reniform followed by a sharp black tooth, facing 
two black teeth from submarginal line; hindwing pearly white, with veins and termen dark. This cosmopolitan 
species occurs throughout India, in Ceylon, Java, Celebes, New Guinea, Australia, New Zealand, New Hebri¬ 
des, Haw r aii, and Lifu, Loyalty Islands. The form found in these last localities, culminating in the New Zealand 
aneituma. examples, is the form aneituma Walk. (7 a); in the <$$ of these the costal third is intensely black, and in the 
$$ the whole forewing except the space between outer and submarginal lines; the white hindwing being almost 
pemigrata. entirely suffused with blackish as well; in ab. pernigrata ab. nov. (7 a) the darkest form of the the whole 
wing is suffused with dark. In Vol. 3, pi. 8c we have given the pale European form, here, (6 k) are given dark 
Polynesian specimens. Larva dirty grey brown, with the lines paler but obscure; tubercles black; head light 
brown; polyphagous on low plants. 
spina. R. spina Oven. (= nitida Walk., tenebrosa Walk., vastator Scott) ($ a). Forewing greyish red brown - 
tinged with rufous in the ; the cell black brown, projecting as a spike beyond reniform to outer line; stigmata pale, 
grey with darker centres; claviform small, slightly outlined in black; lines inconspicuous; the inner double, 
outcurved between, the veins, varied with pale grey scales like the whole basal area; outer line double, dark, 
indistinctly dentate on veins; submarginal pale, waved, in a deeper terminal shade; hindwing dark brown, paler 
obfuscata. towards base; veins and cell sjzot, dark. Australia and Tasmania. A form of the $ occurs — ab. obfuscata ab. 
nov. (7 b) in which the dark fuscous suffusion is strong enough to conceal all the markings except the upper 
stigmata, which are pale grey, and the dark streak through cell; of the 2 examples in the Tring Museum referable 
to this aberration one is without locality; the other is labelled Invercargill, New Zealand, a locality from which 
the species does not seem to have been hitherto recorded; it differs only in being slightly smaller.
