Zamarada variola sp. n. 



(Text-figs 447, 448; PI. 93, figs 830, 831; PI. 123, fig. 1098) 



J $ (PI. 123, fig. 1098). Hyaline area of wings greenish tinged and coarsely striate with 

 grey, the grey being vinaceous tinged in oblique light; distal margin of hyaline area without 

 slender, dark, marginal line; discal spots grey, that on fore wing large with a few light scales 

 medially. Non-hyaline terminal area uniformly brownish grey (pi. 5, E2, elephant-skin 

 grey) ; subterminal fascia indicated only by small, slightly darker grey, interneural spots, 

 each edged distally with a few buff scales. Underside of non-hyaline terminal area uniformly 

 brownish grey. 



In the male the hind tibia is dilate with a short-scaled, longitudinal pocket. 



$ genitalia (Text-figs 447, 448). Uncus asymmetrical; left lobe produced to acicular apex, 

 right lobe atrophied. Ventral plate of gnathus asymmetrical and strongly sclerotized, with 

 a long, scobinate, tongue-like process at right side. Valves asymmetrical. Aedeagus tapered 

 and scobinate along left side at three-fourths. Fulcrum broadened and scobinate apicad. 



Coremata buff. 



O. genitalia (PI. 93, figs 830, 831). Collar-like sterigma asymmetrical, more broadly developed 

 at right side where sclerotized ductus bursae is attached, and overlaid along anterior margin 

 by a bilobate fold; a small hemi-spherical, sclerotized area at mid-posterior margin. 



Measurements. Fore wing: <J 20-22 mm; $ 18-21 mm. Antennal pectinations: (J 7 X, 

 $ 5 X diameter of shaft. 



Similar in colour and pattern to latimargo, but differing in the greenish-tinged 

 hyaline area and the absence of a slender, dark brown distal margin to the area. 

 Males may be further distinguished from latimargo by the absence of long hair- 

 scales on the hind leg. In the male genitalia the form of the uncus, ventral plate 

 of the gnathus and valves and in the female genitalia the form of the sterigma 

 are diagnostic.
