Zamarada eurygnathus sp. n. 



(Text-figs 21, 22; PI. 96, fig. 852) 



$ (PI. 96, fig. 852). Hyaline area of each wing lightly irrorate with brownish orange and 

 black, mainly in medial area to form an ill-defined medial fascia. Non-hyaline terminal third 

 of each wing brownish orange (pi. 5, C5, topaz), irrorate and patterned with black as illustrated; 

 basal area of each wing black. 



^ genitalia (Text-figs 21, 22). Uncus with rounded tip, base with long setae dorsally. 

 Ventral plate of gnathus broad, apical margin curved. Valve simple, apex slightly tapered; 

 dorsal process with acicular projection at two-thirds. Fulcrum about four-fifths as long as 

 aedeagus, apex spatulate; apical half of aedeagus slenderly and smoothly sclerotized at one 

 side. Vesica with a dense cluster of spines. 



5 unknown. 



Measurements. Fore wing: $ 12-5 mm. Antennal pectinations: $ 13 X diameter of shaft. 



Differs from the closely related townsendi in the form of the ventral plate of the 

 gnathus, the longer, acicular projection from the dorsal process of the valve and 

 the smoothly edged, sclerotized apical half of the aedeagus. 



Distribution. Kenya.

Zamarada anacantha sp. n. 



(Text-figs 23, 24; PL 4, figs 467, 468; PL 95, fig. 847) 



$ $ (PI. 95, fig. 847). Hyaline area of each wing irrorate with brownish orange and grey 

 and finely edged distally with black; antemedial and medial fasciae dark grey, the former 

 usually sharply marked, the latter ill-defined and often wanting. Non-hyaline terminal 

 third of each wing brownish orange (pi. 5, C6, Pompeian yellow) proximad of dentate sub- 

 terminal fascia, elsewhere densely irrorate with dark and silvery grey and lightly irrorate 

 with black. 



(J genitalia (Text-figs 23, 24). Apical third of uncus produced to blunt tip; base with long 

 setae dorsally. Ventral plate of gnathus broad, rounded and scobinate. Valve simple 

 with narrowly rounded apex; dorsal process sharply angled at two-thirds, without projection. 

 Fulcrum subequal in length to aedeagus; a pair of strongly sclerotized, scobinate projections 

 at two-thirds; aedeagus sclerotized in apical half and serrate at one side. Vesica with a 

 dense cluster of spines.
