Zamarada labrys sp. n. 



(Text-figs 31, 32; PI. 6, figs 475, 476; PL 96, fig. 855) 



{Zamarada pulverosa Warren sensu Swinhoe, 1904 : 516 {nee Tana R. $). Misidentification]. 

 [Zamarada phaeozona Hampson, 1909 : 123, subsp. 1. Misidentification.] 



^ $ (PI. 96, fig. 855). Hyaline area of wings usually densely irrorate with yellowish brown 

 and grey and finely edged distally with black; antemedial fascia on fore wing and medial 

 fascia on each wing dark grey to black, usually ill-defined, sometimes absent. Non-hyaline 

 terminal third of each wing yellowish brown to light brown, varyingly irrorate with dark grey 

 to black; dentate subterminal fascia broken and black, usually most clearly indicated by its 

 fine distal edging of white scales. 



<$ genitalia (Text-figs 31, 32). Uncus evenly tapered to rounded apex; base with long 

 setae dorsally. Arms of gnathus broad; ventral plate deep with small tongue-like projection 

 medio-posteriorly. Valve simple, broadly rounded at apex; dorsal process with tapered, 

 sclerotized projection at three-fourths. Fulcrum a little longer than aedeagus, apical third 

 scobinate, the tip bearing two or more stout spines; aedeagus smoothly and finely tapered. 

 Vesica with a cluster of short spines. 



$ genitalia (PI. 6, figs 475, 476). Ostium bursae smaller than area of signum; posterior 

 margin of lamella postvaginalis curved. Posterior half of corpus bursae sclerotized and 

 narrowed posteriorly; signum ovate and stellate. Seventh sternum sclerotized in distinctive 

 form, as figured. 



Measurements. Fore wing: $ I2'5-I4'5 mm; 9 14 mm. Antennal pectinations: J 14 x, 

 $ 3 X diameter of shaft. 



Externally rather like a large example of phaeozona, for which Hampson under- 

 standably mistook it. Structurally the form of the gnathus, of the dorsal process 

 of the valve and of the smoothly tapered aedeagus in the male genitalia and the
