REVISION OF GENUS ZAMARADA 105 



simple and boldly rounded apicad in protrusa, sinecalcarata, disparata, antimima, 

 bernardii and carcassoni; in other species the apices are tapered; only in strigilecida 

 is the valve ornamented, the dorsal margin being coarsely scobinate. 



In the male the hind tibia is simple in all species except urania, in which there 

 is a very short tuft of specialized scales; these are more readily discernible in 

 slide-mounted specimens. 



Key to Species and Si bspecies 



1 Projection from three-fourths aedeagus acicular, its ventral surface, next 



aedeagus, scobinate .......... 2 



Aedeagus with or without projection; if present, projection never scobinate. 3 



2 (1) Apex of dorsal margin and apical margin of valve angled at 90 degrees and 



smooth-edged I ateral margins of fulcrum crenulate at two-thirds. 



bernardii (p. 1 1 1) 



- Apex of dorsal margin of valve produced and Berrate-edged. Fulcrum with 



a pair of angular projections at two-thirds . . . .carcassoni (p. no) 



3 (1) Apex of valve truncate or broadly rounded, all margins smooth, broad .ipical 



margin not less than one-half of the greatest width of the valve. Cornutus 

 straight and acicular .......... 4 



- Apex of valve tapered or apex of dorsal margin prodnced and t.ipered; or 



apex narrowly rounded with dorsal margin weakly Berrate apicad and 



with a hook-like cornutus curved through 00 degrees .... 9 



4 (3) Aedeagus with acicular projection at three-fourths ..... 5 



- Aedeagus without projection ......... 7 



5 (4) Valve truncate; apex of ventral margin abruptly curved, that of dorsal margin 



angled through 90 degrees (Text-fig. 173). Apical sixth of aedeagus with 

 conspicuous, sclerotized longitudinal ridge. Non-hyaline terminal area 

 of wings predominantly orange-grey .... antimima (p 111) 



- Apex of valve rounded, ventral margin gently and gradually curved (Text-fig. 



161). Apical sixth of aedeagus without longitudinal ridge 6 



6 (5) Fulcrum with a pair of angular projections at two-thirds. Distribution: 



Guinea to Nigeria ...... protrusa protrusa (p. 107) 



- Fulcrum without a pair of angular projections; apical third smooth or serrate 



protrusa serrula (p. 108) 



7 (4) Greatest width of valve equal to two-thirds of length of its dorsal margin, 



from apex to base of dorsal process. Apical third of fulcrum serrate-edged 

 or bearing a pair of angular projections at three-fourths. Hyaline area 

 extending distad between veins M 3 and 0< lb similarly on fore and hind 

 wings ............. 8 



Greatest width of valve equal to length of its dorsal margin, from apex to 

 base of dorsal process. Apical eighth of fulcrum serrate-edged. Hyaline 

 area between veins M, and Ca lb extending to one-half non-hyaline terminal 

 area of fore wing, but to termen on hind wing . . disparata (p. 109) 



8 (7) Fulcrum serrate-edged in apical third. Acicular cornutus one-half as long 



as greatest width of aedeagus. Hyaline area extending to termen between 

 veins M 3 and Cu lb on each wing .... sinecalcarata (p. 108) 



- Fulcrum with a pair of angular projections at three-fourths. Acicular cornutus 



equal in length to greatest width of aedeagus. Hyaline area extending 

 to one-half non-hyaline terminal area between veins M 3 and Cu lb on each 

 wing .......... lanceolata (p. 109)
