GENERA OF AFRICAN LYCAENIDAE 227 



At that time, having no material of P. dana, I accepted Corbet's opinion. Since 

 then, I have been able to dissect three males from the British Museum (N.H.) and to 

 figure the male genitalia (Text-fig. 198). A glance at this figure will show they bear 

 little resemblance to the genitalia of sichela : the uncus is much simpler, the vin- 

 culum very narrow and devoid of a saccus ; the valves bigger and well separated, 

 and the penis disproportionately large in relation to the dorsal structures. I 

 consider therefore that there is good reason to retain the genus Pseudonacaduba for 

 the two African species in spite of the undeniable superficial resemblance between 

 dana and sichela.

Male genitalia (Text-fig. 199). Uncus composed of two small lobes (" cheeks " of Bethune 

 Baker) fused to the lateral angles of the tegumen ; subunci long, curving, tapering gradually 

 to the apex ; tegumen consists of a median strip excised on its posterior edge ; vinculum fairly 

 wide ; lower fultura comprising two small divergent arms fused to the base of the valves, and
