Zamarada volsella sp. n. 



(Text-figs 441, 442; PL 92, figs 824, 825) 



<§ genitalia (Text-figs 441, 442). Uncus bilobate, the lobes more widely separated at base 

 than in eucharis. Ventral plate of gnathus asymmetrical, shallower in depth than eucharis. 

 Valves usually symmetrical and narrowed apicad; apex of left valve occasionally with second 

 thorn-like projection; dorsal process weakly spined. Fulcrum dilate and coarsely scobinate 

 at apex. 



§ genitalia (PI. 92, figs 824, 825). Ductus bursae enclosed in a strongly sclerotized, 

 asymmetrical sterigma, the ventral surface of which is scobinate and bears a transverse, 

 posteriorly bilobate fold on anterior margin; a short, smoothly tapered, digitate projection 

 extends from left side of posterior margin of sterigma. 



Measurements. Fore wing: $ i5'0-iy5 mm; Cj 16 mm. Antennal pectinations: $ 7 X , 

 $ 3 X diameter of shaft. 



Apparently indistinguishable on external features from eucharis; their respective 

 distributions do not, however, appear to overlap. In the male genitalia the form 

 of the valves, the shallower, asymmetrical ventral plate of the gnathus and the 

 apically dilate fulcrum and in the female genitalia the form of the strongly 

 sclerotized sterigma are diagnostic. 



Distribution. Cameroun, Gabon, Zaire.

Zamarada deformata sp. n. 



(Text-figs 443, 444; PL 92, figs 826, 827; PL 123, fig. 1103) 



^ $ (PI. 123, fig. 1 103). Externally closely similar to smaller examples of paxilla, with 

 which it occurs. Distinguished in both sexes by the shorter antennal pectinations, which 

 are five times instead of eight times as long as the diameter of the shaft in the male and twice 

 as long instead of four times as long as the diameter of the shaft in the female. The male 

 may be further distinguished by the absence of long, fringing hair-scales on the hind femar; 

 the hind tibia is dilate with a short-scaled, longitudinal pocket, three-fourths as long as the tibia. 



(J genitalia (Text-figs 443, 444). Uncus asymmetrical and irregularly bilobate. Ventral 

 plate of gnathus grossly asymmetrical and minutely scobinate. Valves asymmetrical, twin
