Gonoreta bispina sp. n. 



(Text-figs. 145-148 ; PI. 8, fig. 304 ; Map 4) 



Description. q"- Palp scarlet. Head scarlet with buff dorsoposterior margin. Antennal 

 shaft buff dorsally. 



Dorsal surface of thorax purplish brown with nearly white anterior margin ; except at 

 anterior margin of thorax the scales are white-tipped with dark band immediately below tip. 

 Ventral surface of thorax orange, but scarlet anteriorly at side of eye and buff above level of eyes. 

 Legs scarlet on outer surface, orange on inner surface ; fore legs the most intensely coloured. 



Colour-pattern and shape of wings as in Plate 8, fig. 304. Ground-colour of upper surface of 

 fore wing purplish grey, transversely striate with dark grey especially posteriorly ; medial shade 

 and cell-spots purplish grey ; subterminal fascia reddish brown, edged distally with white. 

 Upper surface of hind wing dull purplish brown, with darker medial shade and whitish cell-spots. 

 Under surface of both wings dull scarlet-orange, becoming less reddish proximally on fore wing 

 and posteriorly on hind wing ; irregularly marked with red and grey striations. Fore wing with 

 well marked, broad, dark grey, postmedial fascia ; hind wing with trace of this fascia at anterior 

 margin. 



Abdomen purplish brown above, except for orange posterior tufts ; scarlet-orange beneath. 



o* genitalia as in Text-figs. 145-147. Aedeagus with short apical spine. 



$. Most specimens differ from the male in the following respects : fore wing less strongly 

 falcate ; ground-colour of fore wing usually yellowish brown, strongly striate, and ground-colour 

 of hind wing dull yellow-brown ; under surface of both wings buff or pale orange, usually without, 

 but in some specimens with, trace of postmedial fascia ; abdomen as for colour of adjacent 

 surfaces of hind wing. Four of the females examined, however, were similar in colour to males. 



$ genitalia (Text-fig. 148) without signum on bursa copulatrix. 



Measurements. A.P.R. : $. 10 ; $. 6. Wing : <$. 17-0, 14-5-18-0 mm. (7) ; $. 18-5, 

 170-21 -o mm. (11). 



Discussion. The close similarity in the colour-pattern, the shape of the apical 

 part of the aedeagus, and the length of the antennal pectinations in the males 

 (A.P.R. = 1 in both species) suggest a close affinity between this species and the 

 African opacifinis. The shape of the eighth abdominal sternum in the male readily 

 separates bispina from opacifinis. 



There is little individual variation in the males examined, but four of the females 

 have darker, less strongly striate wings as in the males. 



Distribution (Map 4). Madagascar. 



Material examined. Type. Holotype <$, Madagascar Est, Route d'Anisobe 

 km. 57, 18.ii.1955 (Viette) ; Drepanidae genitalia slide No. 619 ; in the Museum 

 national d'Histoire naturelle, Paris.
