T. nigra Warr. (4f). Forewing purplish black; the lines, which are double, the edges of the stigmata, nigra. 
and the praesubmarginal shade deep black; the narrow terminal area, the centres of stigmata, and the costal 
spots dark grey; the inner and outer lines conversely lunulate dentate; hindwing yellowish straw colour, deeper in 
the $; veins towards termen black; fringe black; a fuscous terminal border, ill-defined in <$, complete in the 
Khasia Hills, Assam. In the form from Burma, — subsp. fuscipennis Warr. (4 f) the whole hindwing in the fuscipennis. 
$ is bronzy fuscous; the outer line in both wings on the under side is more elbowed in the middle. 
T. pallidipennis Warr. (4f). Like nigra, but the ground colour paler and greyer; the black suffusion pallidipen- 
not so complete; the lines filled up with grey; hindwing uniform pale strawcolour; the fringe dark fuscous; nis - 
faint traces of a dark sub terminal shade. Java. 
Sect. II. Antennae of £ fasciculate only. 
T. variegata Moore (4g). Forewing bright brown sprinkled with snowwhite; the lines and shadings variegaia. 
deeper brown; inner and outer lines double, waved, filled in with white, and with whitish irroration on both 
sides; a fascia before inner line, the median shade, and the area between outer and subterminal lines darker, 
the last much irrorated with white; veins dark, peppered black and white; stigmata inconspicuous; the orbicular 
round, the reniform lunulate, both fulvous with black outlines, the reniform with a white dot at its upper 
and lower end; subterminal line broad, bronzy yellowish; the dark veins marked across it by white teeth; the 
apex dark; fringe mottled dark and light brown; hindwing shining orange, with a marginal band and the fringe 
olive fuscous; in the § the band is broader. Occurs in the Khasia and Naga Hills, Assam, and in Sikkim and 
Bhutan. 
T. subflava Wileman (4g). Forewing white, with olive grey irroration and suffusion; subbasal line subflava. 
sharply angled and placed on a white costal patch; inner line thick, black, acutely angled outwards below sub¬ 
costal and median veins, and inwards on the median and vein 1, accompanied by white scaling on both sides; 
outer line black, lunulate dentate, inangled below subcostal and median veins and with white scaling on both 
sides, very broad at costa and on each side of vein 6 beyond cell; median shade thick, conspicuous towards 
each margin; stigmata with interrupted black outlines, and grey and white inside; subterminal line indistinct, 
whitish, preceded by a row of black wedge-shaped marks; dark terminal lunules in a white festoon; hinclwing 
orange, with the fringe, the terminal lunules, and a few r subterminal clouds olive fuscous. Khasia Hills. Assam; 
Formosa; also in W. China. 
T. infausta Walk. (4g, h). Forewing shining iron grey speckled with darker; the hues black; the inner inf av si a. 
and outer double; the inner irregularly waved, the outer lunulate-dentate, incurved below middle; median 
shade single, distinct; stigmata black-edged, the orbicular round, the reniform preceded by a black bar, some¬ 
times followed by a pale patch before outer line; subterminal line pale grey, preceded by an irregular black 
shade; marginal lunules and the fringe blackish; hindwing bronzy fuscous with dark terminal line and the veins 
blackish; in the $ the extreme termen is paler, more broadly at apex; the $ is generally darker than the $. As¬ 
sam, Sikkim, Bhutan, and the Punjab. 
T. flavata Moore (4 f). Forewing grey overlying a whitish ochreous ground, which shows only along flavata. 
costa; a tint of pale brownish along both folds, strongest in postmedian area and extending along termen; 
lines dark fuscous, fine; the inner crenulate, oblique inwards from costa to below vein 1, there out.curved, and 
slightly angled outwards on subcostal vein; outer line lunulate-dentate, projecting subquadrately between veins 
8 and 4, thence incurved; praesubmarginal shade dark fuscous, running parallel to outer line, but strongly in¬ 
curved on each fold, dark fuscous mixed with brown, the brown sometimes preponderating; an indistinct dark 
median shade; stigmata pale with fuscous outlines, the orbicular round, the reniform constricted at middle; 
some indistinct dark lunules along termen edged with grey; fringe grey;hindwing dull straw yellow, brighter 
in the $, the base and a dentate-edged submarginal band from before apex to anal angle fuscous grey; fringe 
mottled grey and straw colour, beyond some dark terminal lunules; $ rather larger than $. Found in Bhutan 
and Sikkim, N. India. 
3. Subfamily Bryophilinae (= Metachrostinae in Vol. 3). 
Like the two preceding subfamilies the Bryophilinae are separated from the rest of the Noctuidae by the 
habits of the larvte. These subsist solely, as far as is known, on various species of lichens, resting concealed by 
day in holes and crevices, and rambling abroad only after dark, when their food becomes softened by the dew 
and moisture of the night. I have seen it stated that the larvae should be looked for only when the weather is 
wet; but it is more probable that the few individuals then seen have been driven out of their shelters by 
heavy rains succeeding a dry spell, than that they come forth of their own accord to feed by day. Such, 
at least, is my own experience with the two species which alone occur commonly in Britain. The larvae them¬ 
selves are of a soft and flabby consistence, with sparse short hairs growing from the small warts; they feed up 
in the early summer, pupating in situ in a spun cocoon in the shelter of holes and ledges. The coloration of 
the larvae is not protective, —- a fact which affords additional reason for their nocturnal feeding; but that of the 
imagines corresponds in a remarkable manner with the different hues of the lichen-covered surface on which 
they rest.
