0. rectimarginata Hmps. (43 e). Forewings pale grey-brown, with heavy black scales at costa. A reddish rectimargi- 
yellow line on inner margin. A black dot on disco-cellular comprises the only marking. Hindwings creamy 
white, widely brownish at inner margin. From Sikkim, Bhutan, Andamans, one specimen known from each 
locality. 28—32 mm. 
0. acypera Hmps. (43 e). Forewings pale grey-brown, also with black scales. To judge by the illustration acypcru. 
the costa of this species appears to be somewhat paler, in rectimarginata it is darker. Also here, markings 
consist of a single black spot. Hindwings grey-brown with a black central spot. 30 mm. One from Bali. 
0. rectitermen Wilem. & West. Forewings creamy white with scattered dark scales and 3 somewhat rectitermen. 
paler longitudinal streaks. The first from before centre of costa, curved somewhat downwards, then to outer 
margin, somewhat above the centre. The second from base at costa to near centre of outer margin, the lowest 
one straight from base to margin. Hindwings somewhat paler than forewings. The black spot on fore wings 
can also be present. 35 mm. Philippines. 
0. leptoplasta Trnr. Forewings with straight outer margin, angulated above anal angle, ochre-whitish leptopla.sla. 
grey. On costa at % and before % each a quadrate reddish brown spot. Outer margin ochreous reddish 
above the angle. Hindwings angulated at vein 3, grey. Diffuse ochreous brown on costa and at apex. 30 mm. 
New South Wales. 
42. Genus: Tympaiilstes Mr. 
The 2nd segment of palpi with long hairs anteriorly, the 3rd attenuate and long. Antennae of $ almost 
simple. The $ with large fans of hairs laterally on pectus. Forewings with acute apex, outer margin oblique, 
neuration normal. On hindwings vein 3 + 4 stalked, vein 5 arises from lower angle. Type: pallida Mr. All 
species are indo-australian. 
T. testacea Mr. (42 g). Forewings pale ochre-brown to reddish brown with innumerable darker striations, testacea. 
base pale green at costa. A dark diffuse inner line excurved in cell, incurved on submedian fold, then straightly 
outwards. A bold black dot on disco-cellular. The diffuse outer line less boldly excurved behind the cell, less 
heavily incurved on submedian fold. Submarginal band diffuse, sharply dentate. Hindwings yellowish red. 
38—40 mm. Sikkim. 
T. rubidorsalis Mr. (42 b). Forewings pale ochre-brown, a white dot with black outline at disco-cellular, rubidorsalis. 
Traces of an undulate dark postmedian line, about vertically to vein 4, incurved on submedian fold. A parallel 
submarginal line distally. Hindwings white, transparent, pale reddish at inner margin. 46 mm. Punjab. 
T. alternata Warr. Forewings pale grey-brown with greenish sheen. Lines lilac-grey, undulate, double, alternata. 
the branches widely separate. Antemedian line angulated outwards in centre, intertilled with olive-brown. 
A reddish spot, with a black one above, on inner margin at base. Postmedian line excurved to vein 2, inter¬ 
tilled with olive-brown or reddish. Submarginal line very boldly undulate with a faint grey parallel line distally. 
Hindwings brick-red. Both wings of $ paler. Assam. 
T. rufimacula Warr. Forewings grey, dusted with greenish, without striations. Transverse lines rufimacula. 
greenish grey. The inner line excurved to inner margin, the postmedian line excurved below centre, terminating 
near the inner line at inner margin; close behind there is a fainter grey line. Submarginal line consists of 
spots. Cell spot red. Inner margin at base and submedian fold are red, also similarly a spot on vein 3 before 
the submarginal line. Hindwings red. Smaller than testacea. Assam. 
T. fusimargo E. Prout. Resembles rubidorsalis, but forewings are wider and on hindwings the red fusimargo. 
at inner margin is more extensive. The brown annulus at disco-cellular has barely a trace of a white centre. 
Postmedian line indistinctly double, boldly angulated inwards on submedian fold. A double undulate ante- 
median line is indicated. Costa of forewings rather more pronouncedly excurved in than in $. Submarginal 
spots distinct and irregular. Somewhat larger than rubidorsalis . 50—54 mm. Malacca. 
T. flavescens Swh. (42 g). Like a small rubidorsalis. Forewings ochreous yellow. Antemedian line fiavescens. 
only indicated by a dark spot below costa. An obsolescent median line angulated inwards below costa, outwards 
at origin of vein 2, then indiscernibly inwards. A brown dot at disco-cellular. The brown postmedian line is 
much more dentate than in rubidorsalis, otherwise however similar, close distally are traces of a parallel line. 
Submarginal line consists of triangular brown spots. Hindwings transparent white, more widely pale red at 
inner margin than in rubidorsalis. 36 mm. One from Assam. 
T. pallida Mr. (42 g, h). Forewings pale ochreous yellow with very indistinct markings. A rusty brown pallida. 
spot at disco-cellular. Postmedian line obliquely to vein 6, then undulating inwards, vertically from vein 2. 
Submarginal line more dentate than in flavescens, more similar to rubidorsalis. Hindwings white, not reddish 
brown at inner margin, as in the pale, poorly marked rubidorsalis.
