 one-third ............ 3

setose at one-third. Ventral plate of gnathus truncate. Aedeagus with 

 coarse, thorn-like projections in apical fourth .... excisa (p. 68) 



- Apex of valve finely tapered, apical fourth incurved towards uncus and that 



part of ventral margin serrate; dorsal process with setose, spatulate projection 

 at one-third. Ventral plate of gnathus broadly rounded. Aedeagus finely 

 scobinate in apical fourth ...... denticulata (p. 69) 



4 (2) Dorsal process of valve excavate and with a short, angular projection at 



two-thirds. Aedeagus coarsely scobinate at left side in apical third, terminal 

 spine stout and thorn-like ...... scriptifasciata (p. 65) 



- Dorsal process of valve not excavate ........ 5 



5 (4) Dorsal process of valve without dilation in basal third, boldly and smoothly 



curved through 90 degrees to finely tapered apex. Cornutus broad and as 

 long as greatest width of aedeagus (Text-rigs 85, 86). N. India 



symmetra (p. 68) 

 Dorsal process and cornutus not so formed ....... 6 



6 (5) Dorsal process of valve a little dilate in basal third, apical half evenly curved. 



Cornutus shorter than greatest width of aedeagus and broad with a thorn-like 



tip; smooth-edged (Text-figs 81, 82). Java, Malaya . . baliata (p. 66) 



- Dorsal process of valve a little dilate in basal third, and angled at two-thirds. 



Cornutus slender and as long as width of aedeagus, margins minutely 

 scobinate (Text-figs 83, 84). Sumatra, Borneo . . baliata Psubsp. (p. 66) 



Zamarada scriptifasciata (Walker) 

 (Text-figs 79, 80; PI. 18, figs 523, 524; PI. 100, fig. 891) 



Comibaena scriptifasciata Walker [1863] 1862, 26 : 1566. Holotype £. without abdomen, 



Sarawak (BMNH) [examined]. 

 Zamarada scriptifasciata (Walker) Hampson, 1896 : 552. 



(J$ (PI. 100, fig. 891). Hyaline proximal two-thirds of each wing greyish yellow lightly 

 irrorate with greyish brown and finely edged distally with brown. Terminal non-hyaline 

 area greyish brown (pi. 7, D3) lightly irrorate with brown; dentate subterminal fascia brown 

 slenderly edged distally with light buff. Underside of non-hyaline terminal area of each 

 wing uniformly brown. 



^ genitalia (Text-figs 79, 80). Dorsal process of valve excavate at two-thirds, with short 

 angular projection. Aedeagus with two longitudinal serrate ridges in apical third, terminal 

 tooth of one ridge stout and thorn-like. Vesica with a stout, tapered cornutus, one-third as 

 long as aedeagus. 



$ genitalia (PI. 18, figs 523, 524). Sterigma with three processes extending posteriorly; 

 medial process, from lamella postvaginalis, semi-cylindrical in transverse section; longer 

 lateral processes, from lamella antevaginalis, serrate at tips; posterior third of corpus bursae 

 sclerotized and ribbed, remainder membranous with a stellate signum.
