25. Genus: Astictopteriis Fldr. 



Antennae thin, with a slender curved club. Palpi porrect. Vein 11 of the forewing curved back 

 near its base and hence nearer 12; vein .5 nearer 4. Hindwing rounded. Hindtibia with two pairs of spurs. 



A. henrici Holl. (86 h). Black. Forewing beneath sooty brown: apex and costa reddish brown, henrici. 

 Both sexes have usually vitreous white dots in cellules 6, 7 and 8. The ? has often a similar small 

 spot at the base of cellule 3. Hindwing beneath reddish brown, with two darker bands, and some grey 

 dots, which are ash-colour in fresh specimens. West China, extending from there into north-eastern India. 



A. olivascens Moore. Wings dull black-brown, lighter at the apex and along the costa. ^ without olivascens. 

 apical dots; ? with three dots in cellules 6, 7 and 8. Underside of hindwing with dark bands, which 

 are ill-defined above and below the centre of the wing. Central and South China. 



26. Genus: Apostictoptei'llS Leech. 



Antennae thin with slender club, reaching to the middle of the costa. Palpi curved upwards, third 

 segment porrect. Forewing long and narrower, apex obtuse; vein 5 approaching 4 a little. 



A. fuliginosus Leech (86 h). Black. Distal margin of forewing straight from vein 5 to the costa, fuliginosus. 

 thence oblique towards the apical angle, an obtuse angle being formed at vein 5; vein 11 in its normal 

 place. Omi-shan, West China. 



27, Genus: Erionota Mab. 



Club of antenna strong with sharply curved tip. Palpi ascending, third segment concealed. Vein 5 

 of forewing approaching 4 a little. Distal margin of hindwing sinuous. Hindtibia with 2 pairs of spurs. 



E. thrax L. (87 a). Black-brown; Palearctic specimens of this Indian species are much darker than thrax. 

 true thrax. Forewing with three large, long, transparent spots, which are yellow. Underside yellowish 

 brown; the forewing blackish in the centre. Across the hindwing below the middle a dark band-like 

 shadow. This form, named lara Swinh., differs from Indian thrax only in its blackish colour. Himalaya, lara. 

 Manchuria. 



E. grandis Leech (87 a). One-fourth smaller than thrax, deep black, with three spots as in thrax, (jrandis. 

 but small, white and almost square. Underside of hindwing blackish. Centre of forewung lighter. Hind-
