A REVISION OF THE ETHIOPIAN DREPANIDAE (LEPI DOPTERA) 123 



Fore wing slightly falcate (Plate 12, fig. 320) ; outer margin slightly convex. Upper surface 

 of both wings lustrous except for posterior cell-spot on hind wing and dark edge of hyaline patch 

 on fore wing. Upper surface of fore wing pale purplish brown proximally and posteriorly, pale 

 buff apically, speckled with black ; trace of arcuate antemedial fascia and postmedial fascia ; 

 hyaline patch bordered with dark reddish brown. Upper surface of hind wing pale purplish 

 brown except for broad yellow terminal band, speckled with black ; trace of postmedial fascia at 

 anterior margin of wing ; black posterior cell-spot and trace of discocellular spot. Under surface 

 of both wings lustrous yellowish white speckled with black ; speckling heaviest distal to cell on 

 fore wing and anterodistally on hind wing ; fore wing with trace of grey postmedial fascia ; hind 

 wing with black discocellular spot and less well-marked posterior cell-spot. 



o* genitalia (Text-figs. 197-199) : valve with two nearly equal processes ; aedeagus with 

 single irregularly shaped cornutus ; eighth sternum as in figure. 



$. Known only from one example. Similar to male, but outer margin of fore wing slightly 

 more strongly convex, and ground-colour of upper and under surface of both wings reddish buff 

 except for brownish white area posterior to cell under hind wing. 



9 genitalia (Text-fig. 200) : anterior apophyses long ; ostial segment forming sclerotized ring 

 at base of ovipositor lobes ; posterior apophyses short ; signum irregular in shape, elongate. 



Measurements. APR : q*. 12 ; $. 9. Wing : £. 160, 15-0-16-5 mm. (7) ; $. 

 20-5 mm. (1). 



Discussion. Similarities in the male genitalia suggest that boboa is closely 

 related to canescens and viettei from which it can be distinguished by the shape and 

 colour-pattern of the wings, and in the male genitalia by the shape of the cornutus 

 and position of the valve processes. 



Little individual variation in the coloration of the wings is present in the available 

 material. 



Distribution. Known only from east Madagascar.

(Text-figs. 201-203 ; PL 11, fig. 313) 



Description. q\ Palp and front of head grey ; scales of vertex grey at base, nearly white 

 apically ; upper surface of antenna buff (holotype) or greyish buff. 



Dorsal surface of thorax greyish buff (holotype) or grey ; scales whitish apically. Ventral 

 surface of thorax buff (holotype) or greyish buff, except for brown (holotype) or greyish brown 

 band bordering head. Front surface of legs greyish buff (holotype) or grey, remaining surfaces 

 of legs, buff (holotype) or greyish buff ; front leg most intensely coloured ; distal margin of last 

 tarsal segment darker than rest of tibia. Whole of upper surface of both wings lustrous. Outer 

 margin of fore wing slightly convex ; ground-colour of upper surface (Plate 11, fig. 313) buff 

 (holotype) or greyish buff, speckled with dark grey over whole of wing and with pale grey proxi-
