A REVISION OF THE ETHIOPIAN DREPANIDAE (LEPIDOPTERA) 145 



Venation of fore wing as in Text-fig. 230 (/c, may arise closer to end of cell or slightly nearer 

 base of wing than in figure ; R., may arise distal or proximal to the position illustrated). Ground- 

 colour of upper surface of both wings (see Plate 15, figs. 331-333) pale buff (holotype), yellow, 

 pink or orange-scarlet, variably speckled with orange-scarlet, reddish grey (holotype) or yellowish 

 grey ; highly lustrous distal to postmedial fascia on fore wing, otherwise moderately lustrous ; 

 fasciae and subterminal spot (latter sometimes absent on fore wing) dark brown ; under surface 

 of both wings very pale buff or pinkish buff. Fore wing lightly speckled with brown proximal to 

 weakly marked postmedial fascia ; strongly speckled and suffused with brown distally, especially 

 in patch near posterior end of postmedial fascia ; conspicuous dark brown marking at costal end 

 of postmedial fascia. Hind wing lightly speckled with brown ; weakly marked postmedial 1, 151 ia 

 placed approximately parallel to outer margin, expanded into large brown spot anteriorly ; con- 

 picuous dark brown subterminal spot. 



I >orsal surface of abdomen as for adjacent part of thorax, but more yellowish posteriorly and 

 with trace of dark, transverse band continuous with sub-basal fascia of hind wing. Ventral 

 surface of abdomen very pale buff. 



o* genitalia (Text-figs. 232-234) : valves apparently absent ; (?) gnathus bifurcate, with 

 short, setose, digitate process ; uncus slightly clavate ; aedeagus with longitudinal sulcus 

 apically, vesica with group of stout spines ; eighth sternite as in figure. 



9 genitalia as in Text-fig. 231. 



Measurements. A.P.R. : q\ 23 ; 9. 20. Wing : J. 17-5, I5*5-I9'0 mm. (6) ; 

 $. 23-5, 22-0-2.5-5 mm. (3). 



Discussion. The considerable variation in the coloration and degree of striation 

 of the upper surface of the wings mentioned in the description merits special mention. 

 There is also some variation in the venation of the fore wing (see description). 



Distribution. Known only from the Comores Archipelago (holotype) and 

 Madagascar.
