REVISION OF GENUS ZAMARADA 127 



comparable as plain chocolate to milk chocolate; distinguished from it in the male 

 genitalia by the form of the uncus, aedeagus and fulcrum. 



Reminiscent of the ^'one-group, but differing in its smaller size, appreciably 

 less striate hyaline area and the presence of a sharply defined, black discal spot 

 on the hind wing; further distinguished in the male by the fringed femora of all 

 legs and by the grossly dilate hind tibia.

Zamarada similis sp. n. 



(Text-figs 213, 214; PI. 107, fig. 963) 



O* (PI. 107, fig. 963). Differs externally from the similarly patterned xystra with which it 

 occurs in the brownish orange colour (pi. 6, C6, caramel-brown-Cj, reddish golden) of the 

 non-hyaline terminal area of the wing; the lighter brown of -i»iilis compared with the darker 

 xystra is as milk chocolate to plain chocolate. 



(J genitalia (Text-figs 213, 214). Differs from the closely related xystra in the form of the 

 uncus, which is strongly ridged dorsally in keel-like form and in the form of the aedeagus 

 which has an apically rounded, digitate projection at two-thirds. The fulcrum is dilate and 

 spatulate apicad; apex truncate.

The I LA RIA -Group 



Externally reminiscent of dentigera and arguta in the protrusa-gvoup, with which 

 the ilaria-group appears to be related in the form of the uncus and the valve. 



Characterized in the male genitalia by the very weakly sclerotized valve, which 

 has a slender ridge in the apical half parallel with the ventral margin, and with 

 a very weakly scobinate dorsal margin; by the form of the aedeagus, which in 

 its apical two-thirds bears a slender, sclerotized ridge along one side, a thorn-like
