The GAEDEI-Grovp 



Characterized in the male genitalia by the form of the uncus, which has a 

 waist-like constriction medially and at its base a pair of tapered lateral projections, 

 and by the form of the dorsal process of the valve which is broadly dilate at 

 one-third. 



In the form of the valve and aedeagus evidently related to the protrusa-grou-p. 

 The female genitalia, with the small sterigma and sclerotized posterior third of 

 the corpus bursae, show similar affinities. 



Zamarada gaedei (Prout MS) sp. n. 

 (Text-figs 219, 220; PL 44, figs 627, 628; PI. 108, figs 969, 972) 

 [Zamarada polymnia Oberthiir sensu Gaede, 1915 : 116. Misidentification.] 



<J § (PI. 108, figs. 969, 972). Hyaline area of wings greyish yellow irrorate with greyish 

 brown, lightly in male, very sparsely in female. Non-hyaline terminal area of each wing 

 greyish orange (pi. 5, B6, apricot-yellow) suffused as illustrated with greyish brown (pi. 6, D3, 

 cafe au lait), lightly in female (PI. 108, fig. 972), strongly in male (PI. 108, fig. 969); dentate 

 subterminal fascia brownish orange finely edged distally with white, more contrastingly marked 

 in male; cilia chequered greyish orange and greyish brown. In the male the eighth abdominal 

 segment is glossy grey, the scales closely adpressed. Underside of non-hyaline terminal 

 area of wings greyish orange, partially suffused with dark brown; in the male the apex and 

 tornus of the fore wing are of the ground colour; in the female the apex and posterior fourth 

 of the fore wing and the whole of the hind wing are of the ground colour. 



In the male the hind tibia is simple. 



^ genitalia (Text-figs 219, 220). Arms of gnathus broad at base, tapered and weakly fused 

 medially. Valve simple with rounded apex. Aedeagus tapered with one or two very small 

 thorn-like projections at two-thirds. Fulcrum spatulate and rounded at apex, a pair of 

 thorn-like projections at two-thirds. Vesica with a stout, tapered cornutus. 



9 genitalia (PL 44, figs 627, 628). Sterigma with two short, digitate processes extending 

 posteriorly, one from the lamella antevaginalis, one from the lamella postvaginalis. 

 Posterior third of corpus bursae sclerotized, remainder membranous with a circular, stellate 

 signum. 



Measurements. Fore wing: $ 15-17 mm; § 14-15 mm. Antennal pectinations: g 8 X, 

 $ 2 -5 X diameter of shaft. 



Distinct in the colour and pattern of the upper and under surfaces of the wings. 

 In the male genitalia the form of the uncus, the dorsal process of the valve and 

 the aedeagus and in the female genitalia the form of the sterigma are diagnostic.
