A REVISION OF THE ETHIOPIAN DREPANIDAE (LEPIDOPTERA) 93 



and medial process in the diaphragma of the male genitalia are particularly distinc- 

 tive. In coloration Gonoretodes most closely resembles the genera Oreta Walker and 

 Psiloreta Warren, more especially the Indian Psiloreta sanguinea (Moore), although 

 the affinities are probably less close than between Gonoretodes and Gonoreta. 



The genus is at present known only from the type-species, which is confined to 

 Madagascar and perhaps the islands of the Comores Archipelago. 



Gonoretodes timea sp. n. 



(Text-figs. 149-152 ; PI. 17, fig. 341) 



Description. q*. $. Palp scarlet. Front of head scarlet except for buff medial patch 

 ventrally ; vertex dull yellow ; shaft of antennae yellow, darkest proximally, with scarlet tuft 

 at base ; posterior margin of head with scarlet fringe laterally and ventrally. 



Dorsal surface of thorax purplish white, darkest posteriorly, but with yellow transverse band 

 at anterior margin. Ventral surface of thorax buff. Front surface of whole of fore leg scarlet, 

 rear surface dull yellow ; mid and hind leg yellow except for scarlet outer surface of tarsus. 



Upper surface of both wings (Plate 17, fig. 341) yellow ; moderately lustrous except for 

 marginal band of hind wing between M t and anal angle ; variably speckled with reddish brown. 

 Fore wing with reddish brown antemedial and postmedial fascia ; reddish brown medial shade 

 sometimes present between latter fasciae ; discocellular spot white, conspicuous ; terminal 

 markings dark brown, edged distally with white, most strongly developed at tornus, absent at 

 Cu la ; fringe pale grey apically and at Cu la , remainder dark grey, tipped with pale grey. Hind 

 wing with conspicuous, white discocellular spot ; weakly developed antemedial fascia, postmedial 

 fascia and medial shade in anterior half of wing ; white subterminal markings at outer angle 

 bordered by reddish brown area ; fringe pinkish white posterior to Rs, dark brown anterior to Rs. 



Under surface of both wings yellow (more deeply saturated yellow than upper surface) lightly 

 speckled with reddish brown and dark brown. Discocellular spot of fore wing dark reddish 

 brown with whitish centre ; postmedial fascia reddish brown, less strongly marked than on 

 upper surface ; terminal fascia purplish brown edged distally with purplish white, interrupted at 

 Cu la ; fringe as for upper surface. Discocellular spot of hind wing as for fore wing ; weakly 

 developed postmedial fascia present anterior to cell ; terminal fascia as for upper surface but less 

 strongly marked ; fringe pale yellow posterior to Rs, dark brown anterior to Rs. 



Dorsal surface of abdomen reddish buff except for yellow caudal vestiture. Ventral surface 

 of segments 3 to 6 dull scarlet ; remaining sterna pale buff. 



o* genitalia (Text-figs. 149-15 1) : valve broad, flattened ; gnathus without processes ; 

 diaphragma heavily sclerotized medially, with long, posteriorly directed, medial process (dis- 

 placed to left in Text-fig. 150) bilobed, invaginate, setose, sensory sac immediately anterior to 

 gnathus ; anellus strongly sclerotized ; uncus with two pairs of digitate processes ; apodemes of 

 eighth sternite arcuate, posterior margin of sternite with three large heavily sclerotized spines. 



$ genitalia (Text-figs. 152) : ostium opening into sclerotized invaginate pocket ; eighth 

 segment with digitate process laterally ; ninth segment densely setose. 



Measurements. A.P.R. : $. 25 ; 9- 18. Wing : <$. 21-5, 18-5-24-5 mm. (12) ; $. 

 24-0, 22-0-24-5 mm. (5). 



Discussion. Some individual variation is present in the intensity of the colora- 

 tion of the wings. There is also variation in the medial shade, which may be poorly 

 marked (holotype) or well marked on the upper surface of both wings. 



Distribution. Known only from central, east, north-east and north-west 

 Madagascar.
