fascia of fore wing) and dark subterminal spot between Cu la and Cw lb . Postmedial fascia of 

 under surface of fore wing weakly marked except at costa, corresponding in position with same 

 fascia on upper surface of wing. Under surface of hind wing with weakly marked medial fascia 

 corresponding in position with medial fascia of upper surface) and well marked subterminal spot 

 between Cu la and Cu lb . (See Plate 15.) 



<J genitalia : uncus simple, directed anteriorly ; homologies of remaining structures in main 

 body of genitalia doubtful ; vesica of aedeagus spinose ; eighth abdominal sternite with long 

 apodemes ; eighth abdominal tergum little modified. 



$. Similar to male but with outer margin of fore wing more strongly convex at middle. 



$ genitalia : bursa copulatrix without signum ; eighth segment narrow anteroposterior^*, 

 with long apophyses : ninth segment well sclerotized laterally and ventrally, apophyses shorter 

 than those of eighth segment. 



Discussion. I have been unable to find any reference to this genus in the litera- 

 ture subsequent to the date of the original description, Gaede (1927 b and 1931) does 

 not mention Archidrepana. 



The colour-pattern of the wings is similar in many respects to that of the species- 

 group erosa of Epicampoptera, but the venation, antennal structure and genitalia 

 are quite different. The curiously modified male genitalia and the absence of a 

 proboscis separate Archidrepana from all other African and Madagascan Oretinae. 



The only known species, saturniata, is remarkably variable in coloration. 



Distribution. Known only from Madagascar and the Comores Archipelago.

Description. q"> $. Outer surface of palp brown or dark brown, inner surface buff ; 

 terminal segment sometimes paler than more proximal segments. Front of head buff ; vertex 

 very pale buff, nearly white ; dark brown fringe at posterior margin of head laterally and 

 ventrally. Upper surface of antennal shaft very pale buff.
