S. semifervens Wkr. (= lichenaria Wkr., metarhoda Wkr., hyperythrum Hmps.) (42 f). Forewings semifervens. 
pale yellow-brown, basal area of costa and the apical area greenish. Antemedian line dark, undulate, more 
vertical at inner margin. A black dot in centre of cell. Outer line angulated outwards to vein G, vertical 
to vein 4, then incurved to inner margin. A straight dark line with green above from centre of costa to outer 
margin above vein 4. Hindwings rose, paler at base. — punctata Strd. has bolder cell spot and a spot at disco- punctata. 
cellular. — maculata Strd. has a black spot in centre of inner margin. 25—28 mm. India, Andamans, Malacca, maculaia. 
Sunda Islands. 
2. Antennae o f ^ with long cilia. 
E. subrubra Pagst. (31 g). Forewings grey-brown. Inner line oblique to % of inner margin, anteriorly subrubra. 
somewhat excurved, slightly incurved on submedian fold. There are 2 obliquely placed black dots at disco-cellular. 
The obsolete postmedian line is brown, undulate, excurved behind the cell, incurved below it and outwards 
towards the inner margin. A row of brown submarginal dots. Hindwings pale grey, rose at margin. — distincta dislincla. 
Strd. has distinct transverse lines on forewings and is more heavily dusted with brown in the intermediate 
space. 24—26 mm. Borneo, New Guinea, Bismarck Archipelago. 
3. Antennae of $ almost simple. 
E. rufa Hmps. (43 d). Forewings pale reddish brown, deeper brown at base on costa. Further there ruja. 
is a brown streak on costa from centre to apex. A diffuse red-brown oblique median band proceeds from 
it to inner margin. Hindwings pale reddish. 20 mm. One from Sula. 
35. Genus: Ptyonota Hmps. 
Palpi thin, somewhat shorter than in Erizada. Abdomen with wide tuft at base. Forewings with acute 
apex, excised below at margin to vein 4 and beyond boldly incurved. Vein 7 arises widely anteriorly on ac¬ 
cessory cell, 10 + 8 + 9 from its apex. On hindwings vein 3 + 4 on long stalk, 5 preceding close to vein 4. 
Only 1 species. 
P. formosa Hmps. (43 d). Forewings lilac-red with whitish suffusion, except at inner margin in basal formosa. 
area and before the postmedian line. Antemedian line brown, double, undulate,- with white outer edge below 
cell. A brown spot at cell end and a lunule at disco-cellular. From lower angle of cell an incurved line to 
inner margin. Postmedian line white with dark edge on both sides, excurved below costa, then parallel to outer 
margin. A less boldly curved submarginal line is indicated by a dark outer edge. Hindwings pale reddish. 
$ 30 mm. Burma, Singapore. 
36. Genus: Antantlienia Warr. 
Palpi erect, the 2nd segment widely scaled anteriorly, the 3rd segment pointed. Antennae of filiform, 
almost as long as forewings. Thorax with flat tuft posteriorly. Forewings very rounded on all sides, wide im¬ 
mediately from base. Vein 7 + 8 + 9 with short stalk. On hindwings 3 + 4 stalked. Only one species. 
Au. diversicolor Warr. Forewings of $ brilliant olive-green in basal half, intersected near the base divcrsicolor. 
by an undulate white line and edged by a white line from before centre of costa to inner margin before anal 
angle, angulated outwards at upper end of cell, vertical under vein 2. Posterior to this pale blue, becoming 
dark blue before the white submarginal line. The submarginal line ends in a white spot on inner margin, be¬ 
hind it a blue-black patch on costa and below a band of the same colour. Hindwings black. The $ has 
a dark green spot on costa at base, posterior to which is an oblique pale reddish brown band with green spots, 
edged by the white antemedian line. The latter is angulated outwards below costa, angulated inwards in centre 
and then excurved. Postmedian line as in the + incurved below vein 2, the space between these lines is dark 
green. Behind the postmedian line pale brick-red. Marginal spot and band red. 28—32 mm. New Guinea. 
37. Genus: Tridenti frons Warr. 
Proboscis absent, frons with a trident-like projection. Palpi porrect, the 2nd segment densely hairy, 
the 3rd short. Antennae of $ finely ciliate. Abdomen long. Forewings elongate, triangular, with pointed aj>ex. 
Neuration normal. Only one species. 
T. insularis Warr. Forewings ochreous grey, dark brown in and below the cell, also at outer margin, insularis. 
A black streak extends from base below cell. Lines very indistinct. Antemedian excurved above and below 
centre, incurved between and on vein 1. Outer line dentate, excurved around the cell. Orbicular stigma small, 
dark, with pale outline, reniform stigma edged by a pale lunule towards the base, then follows a dark lunule. 
Submarginal line pale with inner triangular black marks. Veins pale grey at margin also median nervure. Hind- 
Avings pale grey. $ 44 mm. Java.
