with toothed inward projection. Patch of spines on inner edge of sacculus near median basal 

 process. Juxta distinctly tri-lobed, two lateral lobes more sclerotized than shorter median 

 lobe. Aedeagus with very strongly sclerotized cornutus with two long spines at each end of 

 plate and several smaller spines. 



$. Wing, 10-5— 12 mm. Colour and pattern as male. Labial palps similar. 



Genitalia $ (PI. 63, figs 393-395). Anal papillae short. Ostium enlarged and strongly 

 spiny. First part of duct enlarged, covered with small sclerotized plates. Bursa covered with 

 minute spines, larger on one side of bursa than the other. 



Discussion. The strongly spotted hind wings together with the angular shape 

 of the fore wing make this species easily recognized. From the closely allied C. 

 unigena it can be separated by the shape of the genitalia. The single specimen 

 from Sao Thome is larger than the Cameroons specimens but otherwise is indis- 

 tinguishable. From C. subscripta this species can be separated by its larger size 

 and heavier black spotting on the wings, the genitalia are quite different. Although 

 little material of C. obstinata is available it has such distinctive genitalic structures 

 that it warrants description.

Cumbaya unigena sp. n. 



(PL 17, fig. 85; PI. 41, fig. 229) 



o*. Wing, 12-5 mm. Vertex light brown. Antennae damaged, probably minutely ciliate. 

 Frons rounded, not projecting between eyes. Labial palps with third segment almost equal 

 in length to second, upturned, not reaching vertex. Thorax light brown. Hind tibia with 

 inner spur of proximal pair 2 X length of outer, reaching almost to tip of shorter distal spur. 

 Distal pair of spurs with outer spur 2/3 length of inner spur. First four hind tarsal segments 

 without spines, last segment with a few spines. Fore wing, pattern as in PI. 17, fig. 85, pale 

 yellowish brown with purplish suffusion to subterminal and median areas. Indistinct transverse 

 reticulations. Small black spot at apex of cell and a few black spots scattered over the wings. 

 Hind part of terminal margin incised. Underside more heavily mottled with black than 

 upper side. Black and silver iridescent scales in cell and along base of anterior veins. Pale, 

 triangular-shaped area extending from apex of fore wing to iA. Black spot at apex of wing 

 between veins, smaller black spots between iA and R 5 . Hind wing, upperside as fore wing, 

 more black spots on wing margin, margin sharply angled. Underside heavily spotted with 

 black. Sc+Rj^ and Rs free. 



Genitalia $ (PI. 41, fig. 229). Genitalia damaged, uncus probably lost. Gnathus a weakly 

 sclerotized loop with minute spines on median part. Valve simple. Prominent toothed median 

 basal process, several strongly sclerotized teeth on inner part of sacculus near median basal 

 process. Juxta a broad plate with lateral arms. Sacculus slightly enlarged. Aedeagus with 

 very elongate and strongly sclerotized spines on manica. 



$. Unknown.
