Zamarada sicula sp. n. 



(Text-figs 132, 133; PL 29, figs 567, 568; PL 103, fig. 920) 



(J 9 (PI- I0 3> n &- ° 20 )- Colour and pattern of upperside of wings similar to those of 

 excavata, but differing in the shallower hyaline excavation of the terminal area of each wing. 

 Underside of non-hyaline terminal area of each wing dark brown, apical area of fore wing 

 light buff. 



Male hind tibia slightly dilate with a tuft of long light buff hair scales on inner surface, 

 near joint with femur. In excavata the male hind tibia is simple. 



£ genitalia (Text-figs 132, 133). Valve finely tapered, apex narrowly rounded and scobinate; 

 dorsal margin sclerotized; dorsal process with a digitate, setose projection at one-fifth; 

 hair-scales of coremata light buff. Aedeagus with a strongly sclerotized, thorn-like projection 

 at two-thirds. Fulcrum with a pair of angular projections, varyingly developed, just beyond 

 one-half. Vesica with a short, stout, tapered cornutus. 



$ genitalia (PI. 29, figs 567, 568). Sterigma slightly asymmetrical, with a short, broad, 

 digitate process extending anteriorly. Posterior third of corpus bursae sclerotized. 



In the male genitalia the form of the valve and of the aedeagus and in the female genitalia 

 the form of the sterigma are diagnostic. 



Measurements. Fore wing: $ § 13-5-14-0 mm. Antennal pectinations: $ 10 x, $ 8
