A REVISION OF THE ETHIOPIAN DREPANIDAE (LEPIDOPTERA) 163 



Nidara croceina Mabille 

 (PI. 18, fig. 347) 



Nidara croceina Mabille, 1897 : 222. 



Nidara croceina Mabille ; Gaede in Seitz, 1927 b : 292. 



Nidara croceina Mabille ; Gaede, 193 1 : 52. 



Description. 9- Palps and head yellow ; antennal shaft yellow dorsally and laterally. 



Thorax yellow dorsally, much paler ventrally. Legs entirely yellow. Upper surface of both 

 wings (Plate 18, fig. 347) yellow ; large white spot between Cu la and Cu lb and trace of second 

 smaller white spot between M 3 and Cw la , both distal to end of cell ; hind wing unmarked. Under 

 surface of fore wing yellow, with whitish spot between Cu la and Cn lb distal to end of cell ; hind 

 wing yellow, unmarked. 



Abdomen missing from lectotype. 



O*. Not known. 



Measurements. A.P.R. : $. 21. Wing : $. 190 mm. (1). 



Discussion. Apart from the lack of striations on the fore wing croceina super- 

 ficially resembles multiversa. 



Material examined. Type. The specimen I consider to represent the type 

 material has recently been discovered amongst some unsorted moths from the 

 Oberthiir collection in this museum. This specimen, which I have selected as 

 LECTOTYPE, bears two labels, " Ex musaeo P. Mabille 1923 " and " Ex Oberthiir 

 Coll. Brit. Mus. 1927-30 " ; but there is no locality label. The original material, 

 according to Mabille (1897 : 222), was collected in northern Madagascar at Diego 

 Suarez by Alluaud. Except for the presence of easily overlooked white spots on the 

 fore wing this specimen matches the short original description. 



Nidara multiversa sp. n. 



(Text-figs. 253, 254, 263-267 ; PI. 17, fig. 340) 



Description. 6*. ?• Palp and head buff ; dorsal and lateral surfaces of antennal shaft black. 



Thorax buff dorsally, paler ventrally. Legs pale yellow. Upper surface of fore wing (Plate 

 17, fig. 340) yellowish buff with numerous transverse striations (very dark brown anteriorly, 

 otherwise reddish brown) ; single white spot close to cell between Cu la and Cu lb ; very faintly 

 marked postmedial fascia in holotype and female paratype. Upper surface of hind wing yellow, 

 with trace of transverse striations along anal margin. Under surface of both wings yellow ; fore 

 wing speckled with grey scales apically (similar to marcus), and with whitish spot in same position 

 as on upper surface ; hind wing unmarked. 



Colour of abdomen as for corresponding surface of hind wing. 



o* genitalia (Text-figs. 265-267) : uncus tapered posteriorly ; valve broad, shaped like bird's 

 head apically, with single acuminate process ; valves placed so that only small membranous area 

 of diaphragma remains posterior to sclerotized band uniting bases of valves ; aedeagus with two 

 longitudinal carinae placed on opposite sides of aedeagus ; eighth sternum with extremely 

 attenuate posterior processes ; short broad apodemes of eighth sternum directed posteriorly. 



$ genitalia (Text-figs. 263, 264) : paired signa strongly concave externally ; acuminate 

 processes of eighth segment ventral to ostium ; ninth segment strikingly developed dorsally. 



Measurements. A.P.R. : <£. 27 ; $. 18. Wing : q\ 17-0, 165-185 mm. (4) ; 

 $. 19-0 mm. (1). 



Discussion. The colour-pattern of both surfaces of the fore wing of this species 

 resembles in certain respects that of marcus : there are transverse striations and a
