Nidara pumilla sp. n. 



(Text-figs. 268-270 ; PL 18, fig. 348) 



Description, q\ Palp, head and upper surface of antennal shaft yellow. 



Dorsal surface of thorax yellow, paler ventrally. Colour of legs doubtful but probably mainly 

 yellow. Both surfaces of fore wings yellow, lightly speckled with pale reddish brown ; upper 

 surface with small whitish spot edged with brown close to cell between Cw la and Cu-^ ; under 

 surface with small brown spot corresponding in position with spot on upper surface. Both 

 surfaces of hind wing yellow. (See Plate 18, fig. 348.) 



<J genitalia (Text-figs. 268-270) : uncus hood-like ; valves without processes ; aedeagus 

 with one short and two long carinae ; eighth sternum with pair of long, non-setose, acuminate, 

 posterior processes. 



$. Not known. 



Measurements. A.P.R. : £. 27. Wing : 3. 11-5 mm. (1). 



Discussion. This species is known at present only from the holotype, but as this 

 specimen is in reasonably good condition and the genitalia are so distinctive I believe 

 that description is justified. The size, colour-pattern and genitalia distinguish 

 pumilla from the rest of the genus. 



Distribution. Known only from south Madagascar. 



Material examined. Holotype^, Ambovombe, 13. i. 1932 (Decary) ; Drepanidae 

 genitalia slide No. 1255 ; in the Museum national d'Histoire naturelle, Paris.
