Th. interrupta sp. n. (89 d). Forewing olive, scantily dusted with a darker colour, with a vertical black 
streak from the origin of 2 upon 1 b, a black cross-vein streak and a distally concave transverse line from the 
costal margin directly befoi’e the apex to the tornus. Hindwing dark grey. Expanse of wings: 21 mm. Ceylon. 
$ type from Poona in the Tring Museum. 
Th. cotesi Swh. Body brown, with pale scales at the end. Forewing brown, strewn with pale scales, a 
pale line (dark in the $) from the apex to beyond the centre of the inner margin. Hindwing almost black, fringe 
paler. Expanse of wings: 22 — 26 mm. Assam. 
Th. jasea Swh. Smaller axxd paler than the preceding species, without markings. Pale pinkish greyish- 
brown, finely dusted with black, hindwing almost black, whitish beneath. Expanse of wings: 24 mm. Canara, 
India. 
Th. separata sp. n. (89 d). Red-brown. Forewing scantily strewn with black atoms, with an indistinctly 
defined broad transverse line from two thirds of the costal margin straight to the tornus. Hindwing from 
greyish-brown to lighter red-brown. Khasis. and $ types in the Tring Museum. 
Th. flavina sp. n. (89 d). Ochreous. Forewing with a brownish oblique line from % of the inner margin 
towards the centi'e of the costal margin which it does not reach, distally bordered with an indistinctly lighter 
colour, another brownish transverse line which is somewhat convex proximally extends from 5 / 6 of the costal 
margin to the tornus. Hindwing and under surface paler yellow. Expanse of wings: 30 mm. Dalhousie. $ type 
ex coll. Harford (British Museum). 
Th. erectistriga sp. n. (89 d). Body and fore wing violettish-brown, fore wing very scantily strewn with 
black atoms, with a straight violettish-black, almost vertical transverse line from the centre of the inner margin 
to the costal margin a little behind the centre. Another straight brown transverse stripe is distally bordered 
with a somewhat paler colour and extends from % of the costal margin to the tornus. Hindwing and under 
surface dark gi’ey. Expanse of wings: 33 mm. Ceylon. $ type from Puttalam in the British Museum. 
Th. grandis sp. n. (89 d). Red-brown, thorax orange-brown centrally. Forewing with a black central 
dot and an almost straight purple black oblique line distally bordered with light bluish-grey, from the inner margin 
behind the centre to % of the costal margin, from where a darker subapical line extends to the margin at vein 3, 
subapical area grey. Hindwing dark greyish-brown. Expanse of wings: 35 mm. Khasis, in June. type in 
the Tring Museum. — The species differs from rufa in its size and a less convex margin and a less rounded apex 
aixd tornus of the forewing. 
Th. rufa Wil. (89 d). Dark red-brown, prothorax and abdomen lighter. Forewing with a fine black 
central dot and a dingy white transverse line proximally bordered with purple black, from % of the costal 
margin to % of the inner margin. From the same place of the costal margin a dark subterminal line extends 
to the distal margin above the tornus, the margin beyond it being dusted with gi’ey. Hindwing almost blackish. 
Expanse of wings; 20—23 mm. Formosa, South China. 
Th. cruda Wkr. (89 e). Ash-grey, forewing with a lustrous bluish-grey tint, with a brown basal area 
and two brown almost parallel transverse lines. Hindwing not paler than forewing. Expanse of wings: 
26 mm. Borneo. 
Th. bhaga Swh. Dark red-brown, vertex, a band behind the collar and apex of abdomen yellow. 
Forewing pale red-brown, basal third dark brown, almost sti’aightly bordered with pale outside; a small dark 
brown spot at the margin below the apex. Hindwing paler. Expanse of wings: 15 mm. Borneo. 
Th. bisura Mr. Forewing from earth-brown to red-brown, base blackened, a somewhat notched 
transverse line below the black central dot which is often surrounded by a lighter colour, another notched 
transverse subterminal line. The greatest pail of the forewing is more frequently darkened blackish, so that 
there are only light areas at the inner margin beside the light distal margin : — f. nigriplaga Sn. (89 e). Expanse 
of wings: 23—-27 mm. —- Larva green, with a blue or brown dorsal line edged bv yellow spots, with several rows 
of green bristle-tufts; polvphagous. Java to Borneo. 
Th. mixta Sn. (89 d). Forewing brownish bluish-grey, strewn with black atoms, antemedian line 
vertical, blackish, mostly only more distinct at the.inner margin, with traces of a blackish transverse line below 
the blackish central dot, a brownish subterminal line from the costal margin before the apex to the margin at 
vein 2, projecting basad opposite the posterior cell-end, straighter in the $, in which also the basal area is 
brownish. Hindwing greyish-brown. Expanse of wings: 20—25 mm. Java to Borneo. 
Th. lutea Heyl. (= nubeculosa Sn.) (89 e). Brownish ochreous, forewing more or less strewn with black 
atoms which are generally more densely strewn in a dot at the cell-end and a larger loose spot distally to the 
posterior cell-end. Sometimes a dentate antemedian oblique line and a straight postmedian one, both only 
distinct in the inner marginal half. Expanse of wings: 30—45 mm. Java, Sumatra, Borneo. 
Th. minima Semp. (= cinereomarginata Btlr.) (89 e). Red-brown, with a blackish central dot of the
