128 AECTIID^E. 



Subfamily NYCTEOLIN^E. 



A group of Arctiidce, many of them coloured green, frequent- 

 ing trees and shrubs. The apex of the fore wing is more or less 

 produced to a point *. 



Larva. Eight pairs of legs : fleshy, with the anal somite tapering 

 to a point. Halms is smooth, the anal prolegs long, and feeds in 

 the open; Earias is sparsely covered with hair, has the anal 

 claspers short, and feeds among rolled-up leaves.

Teinopyga, Feld. Reis. Nov. p. 9, pi. 106, fig. 18 (1875). 



Type, S. calospila, "Wlk., from Java. 



Range. Japan ; China ; Assam ; Java ; Sumatra. 



Palpi porrectly upturned, the 3rd joint slender and long. 

 Antenna3 simple. Tibia3 with the spurs long. Fore wing with 

 the apex subquadrate ; veins 3, 4, 5 from near lower angle of cell ; 

 6 from upper angle; 7 forming a small areole with 8, which gives 

 off 9 and 10. Hind wing with veins 3 and 4 from lower angle of 

 cell ; 5 from above angle ; 6 and 7 from upper angle ; 8 from 

 before middle of cell. 



* The Nycteolince approach the Acontiina in the structure of vein 8 of the 

 hind wing in some forms, but their tree-frequenting habits are very different.
