thorax creamy or maize-coloured, tegulae and shoulder-covers broadly margined with black, the latter with 
a black middle clot; abdomen deep carmine. Forewing creamy or whitish-yellow, suffused with orange at the

8. Genus: Amsacta Wkr. 
Distinguished from Diacrisia by the palpi being long-haired beneath, the long and short double claw 
of the anterior tibiae, and by the posterior tibiae mostly only exhibiting one pair of spurs or by the presence 
of middle spurs, though quite minute ones; besides by the veins 4, 5 of the forewing and 3, 4 of the hind¬ 
wing rising from the lower cell-angle. Hereto belong about 25 species, of which there are 13 from Indo-Australia.

black with a touch of yellow at the sides of the anal segment. Forewing orange-yellow, the apical third and 
the distal two thirds of the costa black, a long, broad, black wedge-shaped spot runs along vein 1 to three 
quarters of its length, a small black spot at the proximal margin as far as near the proximal angle. Hind¬ 
wing black, with a broad orange-yellow distal margin growing narrower towards the anal angle. The 2 (25 b)

spot of the hinclwing extending to vein 4. Dorey, Arfak.
