Diagnosis. The bipectinate antennae and the shape of the hind wing distinguish Epi- 

 campoptera from Gonoreta, the only other African genus likely to be confused with it. The 

 similarly shaped antennae, the presence of a globose clypeo-frons, and similarities in the colour- 

 pattern suggest affinities between Epicampoptera and Negera, but the shape and venation of the 

 wings together with the distinctive genitalia readily separate them. 



Description, q, $. Labrum globose ; antenna bipectinate from base to apex ; proboscis 

 vestigial. 



Meso- and metathoracic legs with single pair of short terminal spurs. Outer margin of fore 

 and hind wing produced between M 3 and Cw la (see plates). Venation of fore wing as in Text- 

 figs. 1, 3. 5c + i? x anastomoses with Rs for short distance distal to end of cell (see Text-fig. 2). 

 Upper surface of both wings brown ; base of fore wing, area distal to postmedial fascia, and 

 irregular medial patch, paler than rest of wing ; subterminal represented in both wings by well 

 defined interneural spots between M 3 and Cw la , less strongly marked spot between Cw la and 

 Cu lh , and an additional marking in hind wing between M 2 and M a . Under surface of both 

 wings paler than upper surface, variously striate with darker brown ; discocellular spot usually 

 well marked ; postmedial fascia present on both wings, sometimes weakly marked on hind 

 wing ; the hind wing fascia not corresponding in position with same fascia on upper surface. 

 (See Plates 1-3, and Plate 17, fig. 342.) 



Male abdomen with brush organ immediately posterior to tympanum (see Text-fig. 4). 



Genitalia (see notes below under species-groups) . Of particular interest in the male are the 

 peculiar sacs in the uncus of the species group seydeli, and the pouch-like diaphragma of the 

 group erosa : in these groups and in strandi the eighth abdominal sternum is greatly modified to 

 form part of the genital apparatus. The peculiar genitalia of efulena are dealt with on page 47.
