A REVISION OF THE ETHIOPIAN DREPANIDAE (LEPIDOPTERA) 55 



Negera clenchi sp. n. 



(Text-figs. 81-83 ; Map 3) 



Description. <J. Outer surface of palp dark greyish brown, inner surface reddish buff ; 

 front of head pale reddish buff ventrally, greyish brown dorsally ; vertex greyish brown between 

 base of antennae, pale buff posteriorly ; head with dark brown fringe posterior and ventral to 

 eyes ; antennae very pale buff. 



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

 surface of fore trochanter pale scarlet, outer surface of rest of fore leg pale brown and scarlet ; 

 outer surface of mid and hind legs pale scarlet ; inner surface of all legs very pale buff. 



Shape of fore wing as in Plate 5, fig. 290 of disspinosa . Colour-pattern of both surfaces of fore 

 and hind wings as confusa. Upper surface of fore wing buff (palest at base of wing and at outer 

 margin distal to Cw la ) with lustrous, pinkish medial area ; large black spot near base of wing 

 between Cu x ^ and lA ; black discocellular spot and apical marking, and black speckling at anal 

 angle. Upper surface of hind wing mainly pinkish buff speckled distally with dark brown and 

 black but reddish brown at outer angle ; speckled with white scales distally between A/ 2 and Cu^. 

 Under surface of fore wing orange-scarlet, with buff costa ; speckled with dark grey, most 

 strongly at anal angle ; postmedial fascia dark grey ; discocellular spot black. Ground-colour 

 of under surface of hind wing similar to fore wing, but slightly greyish except at outer margin ; 

 lightly speckled with dark grey at anterior margin, and paler grey over rest of wing ; discocellular 

 spot black. 



o* genitalia (Text-figs. 81-83) : valve with single, ventrally directed, medial spine ; gnathus 

 with pair of short blunt, medial teeth ; gnathus not produced anteriorly into diaphragma ; apex 

 of aedeagus spinose on one side, vesica with two patches of spines ; eighth tergite with two 

 rounded posterior processes. 

 $. Not known. 



Measurements. A.P.R. : J. 15. Wing : <J. 23 mm. (1). 



Discussion. It seems probable from the evidence provided by the male genitalia 

 that clenchi is most closely related to disspinosa. Externally clenchi is probably 

 indistinguishable from disspinosa, confusa, ramosa and unispinosa but the male 

 genitalia (in particular the valve, gnathus, uncus, aedeagus) readily separate these 

 five species. 



The male genitalia of clenchi are, I believe, sufficiently diagnostic to permit rapid 

 identification and to justify description of this species from a single specimen. 



Distribution (Map 3). Known only from the type locality in Cameroun. 



Material examined. Type. Holotype <$, Cameroun, Efulen, 30.viii.1921 

 (Weber) ; Drepanidae genitalia slide No. 1535 ; in the Carnegie Museum, Pittsburgh. 



Negera ramosa sp. n. 



(Text-figs. 84-86 ; Map 3) 



Description. $. Palp very dark brown. Front of head brown, vertex buff ; narrowband 

 lateral and ventral to eyes very dark brown. Upper surface of antennal shaft very pale buff. 



Thorax and fore legs as for confusa. Mid and hind legs very pale buff but each tarsal segment 

 greyish brown distally. 



Shape and colour-pattern of wings as for confusa. Base of upper surface of fore wings buff ; 

 area between medial fasciae pinkish buff, with paler central area ; area between postmedial 

 fascia and outer margin buff anteriorly, reddish brown posteriorly at outer margin, with darker
