 margin of lamella postvaginalis asymmetrical. 



Measurements. Fore wing: <J 15 mm; § 14 mm. Antennal pectinations: <$ 10 X, $ 3 X 

 diameter of shaft. 



Distribution. Nigeria. 



Holotype <$, Nigeria: south, Ilesha (L. E. H. Humfrey), Geometridae genitalia 

 slide no. 1682, in BMNH. 



Paratypes. Nigeria: holotype data, 2 $; Lagos, 1 J; Ibadan, Jericho, 3.x. 1959 

 (J. Riley), I <J (all BMNH). 



Zatnarada lanceolata sp. n. 



(Text-fig. 166; PI. 35, figs 589, 590; PI. 105, fig. 941) 



^ $ (PI. 105, fig. 941). Hyaline area of wings tinged with greyish yellow (pi. 3, B5, wax- 

 yellow), as in protrusa protrusa, sparsely striate with brown posterior of discal area and finely 

 edged distally with black; costa of fore wing brown irrorate with silvery grey; costa of hind 

 wing and anterior half of subcostal vein grey; posterior margin of each wing brown; discal 

 spots minute, black. Non-hyaline terminal area brownish orange (pi. 6, C6, cinnamon); 

 dentate subterminal fascia brown (pi. 6, D8, light brown) finely edged distally with light buff 

 and weakly suffused proximally with reddish grey; cilia chequered buff and grey. Underside 

 of non-hyaline terminal area light brown (pi. 6, D4) in apical area of fore wing and terminad 

 on each wing, suffused with brownish grey (pi. 6, E2), densely proximad. Tip of abdomen 

 in male suffused with grey. 



O* genitalia (Text-fig. 166). Distinguished from closely similar sinecalcarala by the longer 

 acicular cornutus, which is equal in length to the greatest width of the aedeagus and by the 

 presence on the fulcrum of a pair of angular projections at three-fourths. 



9 genitalia (PI. 35, figs 589, 590). Distinguished from those of the closely similar sinecalcarata 

 by the smaller, less developed sterigma. 



Measurements. Fore wing: q* 14-15 mm; $ 15 mm. Antennal pectinations: J 10 X, 

 $4 X diameter of shaft. 



Closely similar in colour and pattern to protrusa serrula, from which males may 

 be distinguished by the grey-tipped abdomen; in protrusa serrula the tip of the 

 abdomen is brown. Distinguished structurally in the genitalia of both sexes 

 as indicated above. 



Distribution. Gabon. 



Holotype <$, Gabon: Mouila, 25.ix.1964 (P. Darge), in coll. Herbulot, Paris.

Zatnarada disparata sp. n. 



(Text-figs 167, 168; PI. 105, figs 943) 



(J (PI. 105, fig. 943). Hyaline area similar to that of protrusa, extending almost to termen 

 on hind wing between veins M 3 and Ci< lb , but only to one-half of the width of the patterned
