REVISION OF GENUS ZAMARADA 113 



Colour and pattern of upper surface of wings (PI. 106, fig. 946) closely similar to those of 

 protrusa serrula, differing in the rather less extensive penetration of hyaline into the non- 

 hyaline terminal area of the wings between veins M s and Cn lb . Underside of non-hyalien 

 terminal area of wings dark brown; apices of fore and hind wings light buff, tornus of fore 

 wing, termen and posterior margin of hind wing buffish brown. 



Measurements. Fore wing: <J 15 mm; $ 13 mm. Antennal pectinations: £ 8 x , $ 3 X 

 diameter of shaft. 



Most surely distinguished from protrusa serrula by the very distinct form of the 

 valve in the male genitalia and by the form of the sterigma and corpus bursae 

 in the female genitalia. 



Distribution. Zaire. 



Holotype $, Zaire ('Belgian Congo'): Ukaturaka (i°56' N. 20°24' E.), 29.xii.1948 

 (2". Wikeley), Geometridae genitalia slide no. 5993, in BMNli. 



Paratype. 1 $ taken with holotype. 



Zamarada ferruginata sp. n. 



(Text-figs 177, 178; PI. 106, fig. 945) 



^ (PI. 106, fig. 945). Non-hyaline terminal area of wings light orange (pi. 5, A4) irrorate 

 with greyish brown (pi. 5, D3), lightly on veins, but densely proxmi.i! foi mmg a band bordering 

 the hyaline area; dentate and broken subterminal fascia brown (pi. 6, D7, raw sienna). 

 Underside of non-hyaline terminal area of each wing light orange suffused with brown 

 proximally, bordering the hyaline area. First abdominal segment with a white spot medio- 

 dorsally. 



<J genitalia (Text-figs 177, 178). Valve of even width to broadly rounded apex; apex of 

 dorsal margin produced in acicular form and inclined towards uncus, its surface minutely 

 scobinate; dorsal process dilate and setose in basal third; hair-scales of coremata light buff. 

 Aedeagus finely tapered apicad with an acicular projection from two-thirds. Apical half 

 of fulcrum slender, smooth and tapered. Vesica with a shoit. thorn-like cornutus. 



$ unknown. 



Measurements. Fore wing: <$ 13 mm. Antennal pectinations: (J 8x diameter of shaft. 



Readily distinguished externally by colour and wing pattern and structurally 

 by the form of the valve and of the aedeagus in the male genitalia.
