by hyaline area as in adiposata; dentate subterminal fascia weakly marked as in bathyscaphes; 

 discal spots sometimes wanting. Underside of non-hyaline terminal area greyish orange, 

 as on upperside, the grey proximal suffusion more strongly marked. 



£ genitalia (Text-figs 232, 233). Valves asymmetrical; apex of each ventral margin 

 produced and tapered, apex of each dorsal margin rounded; left valve with angular projection 

 in apical fourth near dorsal margin. 



9 genitalia (PI. 47, figs 637, 638). Lamella antevaginalis similar in form to that of 

 bathyscaphes, but ornamented with spine-like projections; lamella postvaginalis with a pair 

 of strongly sclerotized lateral ridges. 



Measurements. Fore wing: <$ 13 mm; $ 13-16 mm. Antennal pectinations: £ 8 X, 

 $ 3 X diameter of shaft. 



Intermediate in pattern between bathyscaphes and adiposata, having the weakly 

 marked subterminal fascia of the former and the less extensive hyaline area of the 

 latter. Female antennae with short pectinations, as in bathyscaphes. In the male 

 genitalia the form of the asymmetrical valves and in the female the form of the 

 sterigma, especially the laterally ridged lamella postvaginalis, are diagnostic. 



Distribution. Rhodesia.

Zamarada aequilumata sp. n. 



(Text-figs 234, 235; PI. 47, fig. 641; PI. 49, figs 646, 647; PL 109, fig. 976) 



$$ (PI. 109, fig. 976). Basal area of fore wing and non-hyaline terminal area of each wing 

 greyish orange (pi. 5, B5-pl.6, B4), the latter suffused proximally with grey; non-hyaline 

 terminal area less broad than in the preceding species and with less deep intrusions of hyaline 

 between veins M 3 and Cu lb ; ill-defined subterminal fascia dentate, brownish orange; discal 

 spots sometimes wanting. Underside of non-hyaline terminal area of wings light orange 

 (pi. 5, A4) to brownish orange suffused with dark grey proximally, anterior of vein M s on 

 each wing and posterior of vein Cu lb on fore wing. 



$ genitalia (Text-figs 234, 235). Valves symmetrical and ovate, each with a strongly 

 sclerotized, thorn-like apical projection; dorsal process with a setose, digitate projection at 

 one-third. 



$ genitalia (PI. 47, fig. 641; PI. 49, figs 646, 647). Sterigma symmetrical, as illustrated; 

 lamella antevaginalis with a pair of lateral, broad-based, thorn-like projections posteriorly 

 inclined. 



Measurements. Fore wing: <§ 12— 15 mm; $ 13mm. Antennal pectinations: £ 9 X, 

 $ 2 X diameter of shaft. 



Distinguished externally from the preceding species in the group by the paler 

 coloured and narrower, non-hyaline terminal area of each wing and by the shallower 

 hyaline intrusions between veins M 3 and Cu lh . In the male genitalia the 

 symmetrical valves and in the female the symmetrical projections from the lamella 

 antevaginalis are diagnostic. 



Distribution. Tanzania, Zaire, Zambia, Malawi.
