A REVISION OF THE ETHIOPIAN DREPANIDAE (LEPIDOPTERA) 151 



Thorax and legs of type nearly devoid of scales, probably similar in colour to corresponding 

 surface of wings. Shape and colour-pattern of wings as in Plate 16, fig. 336. Venation of both 

 wings as for serena, but R t fuses with R 2 + 3 j ust proximal to branching of R 2 from stalk. Ground- 

 colour of both wings pale brownish grey ; markings brownish grey. Lustrous scales forming line 

 just below costa on fore wing ; scattered at apex, on cell-spots, apical streak, antemedial fascia 

 and anterior half of wing ; and forming line along distal border of postmedial fascia. Lustrous 

 scales also present on hind wing on posterior part of antemedial fascia and along distal border of 

 postmedial fascia. Fringe of both wings brown. Underside of both wings lilac-grey, without 

 markings. 



Colour of abdomen doubtful. 



o* genitalia as in Text-figs. 241-243. Valve with small, digitate, ventral lobe at base. 

 (Aedeagus drawn from side ; ventral view similar to Text-fig. 248 of serena nigeriensis .) 



$. Not known to me. Gaede listed 1 g and 1 $ in his original description, but I was not able 

 to find the female at Berlin. 



Measurements. A.P.R. : (J. Not known. (Neither antenna complete.) Wing : q* 

 11 -5 mm. (1). 



Discussion. This species is separated from both serena and macnultyi by the 

 straight, uniformly marked postmedial fascia on both wings (Plate fig. 336), and 

 by the position of this fascia well away from the outer margin on the hind wing. 

 The presence of a small, digitate lobe at the base of the valve and the broader pro- 

 cesses of the tegumen distinguish the male genitalia from those of serena, the species 

 probably most closely related to argyrobapta. 



Material examined. Type. I have selected and labelled as LECTOTYPE 

 the male syntype : lectotype <$, Sud-Kamerun, Lolodorf, Erich Konrad S.G. ; 

 Drepanidae genitalia slide No. 1229 ; B.M. negative No. 31121 ; in the Zoologisches 

 Museum, Berlin. 



Callidrepana serena sp. n. 



(Text-figs. 240, 244-248 ; PI. 16, figs. 337, 338 ; Map 7) 



Description, <J. Terminal segment of palp very dark brown ; rest of palp brown on outer 

 surface, pale buff on inner surface. Front of head brown, paler towards labrum ; vertex 

 similarly coloured but brilliantly lustrous. Upper surface of antennal shaft brown proximally, 

 buff distally. 



Collar reddish buff ; rest of thorax brownish white. Outer surface of fore tibia and tarsus 

 greyish brown ; remaining legs and rest of fore legs brownish white. Venation : R x and stalk of 

 i? 2 + 3 arise close together from near end of cell ; shortly after branching from R 2 vein R 3 fuses 

 with 7? 4 for variable distance to form areole ; in the hind wing Sc + R 1 anastomoses with Rs for 

 short distance distal to end of cell. Shape and colour-pattern of wings as in Plate 16, figs. 337, 

 338. Ground-colour of both wings pale buff but in some specimens (not holotype) area between 

 antemedial and postmedial fascia dark brown in posterior three-quarters of fore wing and in 

 posterior half of hind wing. Costa very dark brown at base, remainder pale brown. Upper 

 surface with line of lustrous scales immediately posterior to costa from base to near apex ; 

 second line along middle of cell from base of wing ; antemedial fascia double, not developed 

 anterior to cell, proximal line brown and lustrous, distal line pale brown, faintly marked ; 

 irregular marking at distal end of cell, brown or dark brown (holotype), lustrous except at 

 periphery ; irregular, lustrous, brown marking between apex and cell ; postmedial fascia double ; 

 pale brown proximal line hardly discernible, darker distal line lustrous with black spots on veins, 

 expanded at apex ; fringe very dark brown at apex, brown tipped with dark brown posteriorly 

 except at tornus. Upper surface of hind wing with trace of non-lustrous antemedial fascia ;
