REVISION OF GENUS ZAMARADA 187 



(J genitalia (Text-figs 304, 305). Uncus short, stout and tapered. Ventral plate of gnathus 

 digitate and minutely scobinate. Valve with a short medial, diagonal ridge; apex of valve 

 sclerotized and broadly rounded; dorsal process with long, slender, digitate, setose process 

 near base. Aedeagus tapered and blade-like with two rounded projections medially. Fulcrum 

 sinuous apicad, tip heavily spined and extending beyond that of aedeagus. 



$ genitalia (PI. 65, figs 710, 711). Sterigma strongly sclerotized; posterior margin of 

 lamella antevaginalis excavate medially, margin minutely serrate; surface scobinate. 



Measurements. Fore wing: <$ 16-17 mm; $ 15-16 mm. Antennal pectinations: ^ 14 x, 

 9 5 X diameter of shaft. 



Distinct in colour and in the almost straight, distal margin of the hyaline area 

 of the wings. The simple valve structure is similar to that found in a number 

 of species related to bemardii in the protrusa-group, but the valve lacks the 

 dense covering of short hair-scales on the dorsal surface found in those species; 

 distinguished further from them by the shorter, stouter uncus, the well developed 

 gnathus and the form of the aedeagus.

Zamarada griseola sp. n. 



(Text-figs 306, 307; PL 65, figs 712, 713; PL 114, fig. 1028) 



$ $ (PI. 114, fig. 1028). Similar in colour and pattern to astyphela, differing in the extension 

 of the hyaline area of each wing into the brownish orange terminal third between veins M 3 

 and Cw lb . In the male the pectinations of the antennae are slightly shorter than in astyphela. 

 being eleven times instead of fourteen times as long as the diameter of the shaft. 



0* genitalia (Text-figs 306, 307). These differ from astyphela in the form of the strongly 

 sclerotized, sharply tapered apical half of each valve and in the form of the coarsely scobinate, 

 asymmetrical apex of the fulcrum, which has a scobinate projection at the left side. 



$ genitalia (PI. 65, figs 712, 713). Closely similar to those of astyphela. 



Measurements. Fore wing: q* 16-18 mm; $ 15-17 mm. Antennal pectinations: (J 11 X, 

 $5 x diameter of shaft.
