Structurally remote from any species so far known in the genus and placed 

 arbitrarily after the eucharis-gvoup because of general similarity of colour and 

 wing-pattern. 



Zamarada weberi sp. n. 



(Text-figs 451, 452; PL 123, fig. 1100) 



$ (PI. 123, fig. 1 100). Hyaline area of wings tinged with pearl colour, having a vinaceous 

 tint in oblique light; posterior margins very sparsely striate with brown, distal margin 

 slenderly sepia; discal spot on fore wing sepia, pale grey on discocellulars, that on hind wing 

 minute. Non-hyaline terminal area greyish brown (pi. 5, E3, mouse-grey) irrorate with sepia 

 (pi. 5, F4); strongly marked subterminal fascia sepia very finely edged distally with buff; 

 terminal, interneural spots sepia. Underside of non-hyaline terminal area uniformly greyish 

 brown. 



(J genitalia (Text-figs 451, 452). Uncus broad and bilobate. Ventral plate of gnathus 

 broad and deep, margin irregularly and minutely scobinate. Valves simple, but asymmetrical; 

 dorsal processes broadened and setose at apex, the two asymmetrical; no setose projection 

 at base. Aedeagus finely tapered; a diagonally transverse ridge at one-third. Fulcrum 

 scobinate and rasp-like in membranous sheath. No cornutus. 



$ unknown. 



Measurements. Fore wing: <J 1 2 -5-13 -o mm. Antennal pectinations: (J 7 X diameter of 

 shaft. 



Externally distinct in size, colour and pattern. In the male genitalia the form 

 of the uncus and valves is diagnostic.
