A REVISION OF THE ETHIOPIAN DREPANIDAE (LEPIDOPTERA) 139 



Material examined. Type. The holotype of brnnneola {<$, Cameroun, Ogowe 

 River) deposited in the Carnegie Museum has not been seen, but Dr. H. K. Clench 

 kindly sent me drawings of the genitalia and a photograph of the whole insect which 

 enabled me to identify as this species the material listed below.

Description. <$, $. Proboscis vestigial ; palp not extending dorsal to ventral margin of 

 labrum ; antenna unipectinate from base to apex. 



Meso- and metathoracic tibia each with single pair of short terminal spurs. Fore wing weakly 

 falcate ; areole elongate ; R l and R 2 arising from stem of Rs towards distal end of areole (as 

 in Text-fig. 1 of Epicampoptera Bryk, species-group erosa). Sc + R x anastonomising with Rs for 

 short distance distal to end of cell on hind wing. Upper surface of fore wing with conspicuous 

 apical spot, two spots at tornus, strongly marked oblique postmedial fascia, white discocellular 

 spot, and antemedial fascia. Under surface with postmedial fascia corresponding exactly in 

 position with same fascia on upper surface. Hind wing with antemedial fascia on upper surface ; 

 unmarked ventrally. 



o* genitalia remarkable in that the eighth abdominal sternum is fused to the saccus, and the 

 aedeagus to the diaphragma. The diaphragma is invaginated to form a pair of large sacs, 

 enclosing numerous elongate setae. 



$ genitalia also characteristic ; heavily sclerotized. 



Taxonomic History. Bryk (1913) erected this genus for the two species 

 Callidrepana oculata Holland and a new species diagonalis. Gaede (1927 b) in the 

 first revision of the genus added Callidrepana brunneola Holland. In the present 

 revision diagonalis is sunk as a synonym of oculata, and brunneola is transferred to 

 Isospidia gen. n. (see page 132). A further name, Oreta suiphurea Hampson, is 

 added to the synonymy of ocidata. 



Discussion. Characteristic of this monotypic genus is the conspicuous dark 

 apical marking on the fore wing, which immediately separates it from the otherwise 

 similarly patterned and coloured Isospidia gen. n. with which Uranometra has some 

 affinities. The male genitalia, although strikingly different from those of Isospidia 

 in many respects, possess paired elongate processes (possibly representing the 

 gnathus) as in the latter. The eighth abdominal sternum in the female is highly 

 modified in both genera. 



There is apparently no sexual dimorphism in the wing shape and coloration nor in 

 the shape of the antennae. There is some individual variation in coloration. 



Distribution (Map 6). Uranometra is known to range from Ghana across humid 

 central Africa as far as western Uganda.
