Description, q*. Outer surface of palp brown, inner surface light brown. Front of head 

 brown ; vertex brown, becoming more yellowish posteriorly ; narrow, brown band bordering 

 outer lateral margin of eye. Upper surface of antenna! shaft very pale buff. 



Dorsal surface of thorax pale pinkish brown, palest anteriorly ; ventral surface very pale buff. 

 Outer surface of trochanter of fore leg pale reddish brown ; outer surface of rest of fore leg 

 brown ; inner surface of whole of fore leg very pale buff ; colour of remaining legs doubtful. 



Shape of fore wing as for disspinosa (Plate 5, fig. 290). Colour-pattern of upper surface of type 

 as for Plate 5, fig. 288 of quadricornis ; base of upper surface buff in most specimens (including 

 holotype) ; trace of antemedial fascia ; area between antemedial fascia and postmedial fast 1. 

 reddish brown (holotype and one other specimen) or yellowish brown enclosing large lustrous, 

 paler, purplish brown area; small, black discocellular spot ; large, dark spot close to cell 

 between Cu^ and \A (brown in holotype and one specimen, black in two specimens, weakly 

 marked in remainder) ; postmedial fascia buff, edged proximally with brown (holotype and most 

 specimens) or black (one specimen), less strongly edged distally with lighter colour ; area distal 

 to postmedial fascia reddish or yellowish brown near apex and tornus, buff in middle ; sub- 

 terminal fascia represented by short, whitish dashes on veins M 3 to lA ; costa of fore wing and 

 area between antemedial and postmedial fasciae conspicuously lustrous ; whole wing lightly 

 speckled with black (strongly speckled in one specimen, as in Plate 5, fig. 290 of disspinosa). 

 Upper surface of hind wing similar to fore wing in coloration of medial fascia and area proximal 

 to this, but without pale medial patch ; ground-colour of rest of wing similar, but darker at 

 outer angle ; black discocellular spot ; trace of broad, irregular, dark fascia between medial 

 fascia and outer margin in holotype and one other example ; wing lustrous except for marginal 

 band extending short distance posteriorly from outer angle. 



Under surface of fore wing pale yellowish brown (holotype) or pale brownish orange ; lightlv 

 speckled with black or dark grey, most densely speckled along costa and at tornus ; outer mar- 

 ginal band yellow between apex and Cu ia , orange or red between C« la and tornus ; dark grey, 

 oblique postmedial fascia from near apex to about two-thirds distance from base along anal 

 margin, faintly edged distally with a pale line and then a dark line. Ground-colour of under 

 surface of hind wing similar to fore wing but paler ; lightly speckled with dark grey or black, 

 most heavily at costa ; well marked, black discocellular spot ; otherwise unmarked. 



o* genitalia (Text-figs. 75-77) : medial part of gnathus with two short teeth posteriorly ; 

 gnathus extended anteriorly into diaphragma ; valve bifurcate apically ; apex of vesica of 

 aedeagus with minute scobinations at apex and at one side of base ; posterior processes of 

 eighth tergum short. 



$. Not known. 



Measurements. A.P.R. : <$. 18. Wing : q\ 210, 190-230 mm. (8). 



Discussion. I have selected and labelled as LECTOTYPE of lytaea a male 

 syntype from the Druce collection in the British Museum (Natural History). It 

 bears the following data " Ctenogyma [sic] lytaea Type Druce ; Fantee, West 

 Africa, Shelley ; Drepanidae genitalia slide No. 1074 ". The name lytaea was 

 placed in the synonymy of natalensis by Gaede (1927 b : 288) but an examination 

 of the lectotype of lytaea has shown that it is conspecific with the holotype of confusa. 



Distinguished by the male genitalia from ramosa, unispinosa, disspinosa and 

 clenchi, all of which are apparently externally identical to confusa. The genitalia
