O* $ (PI. 98, fig. 874). Hyaline area of each wing very sparsely irrorate with brownish grey; 

 costa of fore wing irrorate with light yellow, yellowish brown and brownish grey; discal spot 

 on fore wing elongate and silvery grey outlined with dark brown, that on hind wing minute 

 and brown, but often wanting. Proximal eighth and non-hyaline terminal area of each wing 

 brownish grey; postmedial fascia, bounding hyaline area distally, dark brown or black edged 

 distally with silvery grey; subterminal fascia brownish yellow edged distally with light yellow; 

 termen slenderly and brokenly dark brown or black; cilia light yellow, chequered with dark 

 brown. Underside of non-hyaline terminal area brown more or less suffused with greyish 

 brown from mid-wing apicad. 



(J genitalia (Text-figs 59, 60). Uncus tapered. Ventral plate of gnathus tapered to narrowly 

 rounded tip. Dorsal processes of valves asymmetrical, serrate-edged in part, as illustrated 

 (Text-fig. 59). Fulcrum extending beyond aedeagus, the tip slightly spatulate and spined. 

 Apical third of aedeagus slenderly produced and sclerotized with a small scobinate area at two- 

 thirds. 



Examples from Air and Damergou in N. Niger differ in the more slender dorsal 

 process of the right-hand valve. 



$ genitalia (PI. 14, figs 505, 506). Posterior third of corpus bursae sclerotized; right-hand 

 margin obtusely angled. 



Measurements. Fore wing: $ 7-5-10-0 mm; $ 8-0-10-5 mm. Antennal pectinations: 

 o* 10 x , $ 4 x diameter of shaft. 



Distinguished superficially from the rather similar minimaria by the more 

 elongate discal spot on the fore wing and by the absence of a yellowish medial 

 fascia from each wing; in the male the presence of a dilate hind tibia with a pencil 

 of long hair-scales distinguishes torrida. In the male genitalia the form of the 

 asymmetrical processes on the valves distinguishes torrida and tosta from related 

 species; the form of the left-hand process in torrida is specifically diagnostic. In 

 the female genitalia the pattern of the sclerotization of the corpus bursae is 

 diagnostic.
