This species was not correctly placed in either Thymistida Warren, which is a 

 genus of a different subfamily (Drepaninae), or in Epicampoptera, all the species of 

 which have differently shaped wings, a different colour-pattern and distinctive male 

 genitalia. 



Material examined. Type. Holotype <J, Gabon, Valley of the Ogowe [Ogove]

Description. <J. Proboscis vestigial. Palp small, extending to just above labrum. 

 Antennae unipectinate. 



Thorax yellow, orange, brown or black. Mid and hind tibia each with one pair of apical 

 spurs. Costa of fore wing weakly arcuate except at base and apex ; apex weakly or strongly 

 falcate, R x arises from short distance proximal to end of cell ; R 2 from short distance proximal to 

 end of elongate areole. R i fuses with R 3 for short distance immediately after branching from 

 R i+ 5 . Fore wing yellow, orange, brown or grey, usually speckled with dark brown or black and 

 with semi-transparent patch or patches at end of cell ; antemedial fascia usually weakly marked ; 

 discocellular spot and posterior cell-spot usually well marked in species-group spicata, usually 

 absent in species-group fenestrata ; oblique postmedial fascia usually well-marked. Hind wing 

 with posterior part of outer margin slightly convex in species-group fenestrata (except in felina), 

 straight or slightly convex in species-group spicata. Sc + i? x anastomoses with Rs for short 

 distance distal to end of cell. Colour of hind wing usually similar to fore wing ; double ante- 

 medial fascia usually present ; cell-spots present or absent. Under side of both wings, yellow, 

 reddish yellow or light brown ; cell-spots corresponding with spots on upper surface ; post- 

 medial fascia usually well marked on fore wing, absent or poorly marked in hind wing, corres- 

 ponding in position with same fascia in fore wing but not in hind wing. (See Plates 11-13.) 



Coloration of abdomen as for corresponding adjacent surface of hind wing. 



<$ genitalia. (Species-group fenestrata, see labelled Text-fig. 188) : saccus broad, shallow ; 

 valve (or derivatives of vinculum) elongate, digitate, with one or more stout processes at base, 

 and long incurved process arising posteriorly ; tegumen with pair of minute, lateral, setose 

 lobes ; uncus simple, tapered ; diaphragma weakly sclerotized medially ; anellus conical ; 

 aedeagus with variously shaped cornutus or cornuti ; eighth abdominal sternum with one pair of 

 posterior processes, without apodemes. (Species-group spicata, see labelled Text-fig. 216) : 

 saccus as above ; valve with four processes, two heavily sclerotized, two weakly sclerotized and 

 digitate ; diaphragma forming a large, weakly sclerotized, anteriorly directed invagination ; 

 anellus a broad, moderately well sclerotized, domed structure surrounding the aedeagus ; 

 tegumen with paired setose lobes ; uncus hood-like, bilobed ; aedeagus large, bilobed at base, 

 vesica partially scobinate but without cornuti ; eighth sternum with bilobed posterior margin, 

 unmodified and without apodemes anteriorly. 



$. (boboa is the only species whose females have been definitely identified.) Probably 

 basically similar to male in all species. In boboa the antennal pectinations are relatively shorter 

 and the outer margin of hind wing is entirely convex.
