(in Seitz, Grossschmett. Erde : 413) he went back on his original opinion in these words : " By 

 a regrettable error of observation, I was induced to describe this form as an Aphnaeus ; on a 

 closer examination I have found that the fore wing has only 11 veins, vein 8 being absent and 

 vein 7 terminating at the apex of the wing as in all the species of Spindasis. The form is in 

 fact so closely allied to S. aderna that I can now only consider it to be the eastern race of it ". 

 This statement, however, only confuses the issue because when I was able to examine closelv 

 the holotype of spindasoides, preserved in the Natural History Museum at Stockholm, I found 

 that in fact it had 12 veins in the fore wing. 



From an examination of a fairly large number of specimens of Lipaphnaeus, the following 

 facts emerge : 



L. aderna aderna : 1 $ Ghana, 1 $ Katanga : n veins. 



L. aderna spindasoides : 3 $ S. Rhodesia, 12 veins ; 1 $ S. Rhodesia, 1 $ Mozambique : 

 11 veins. 



L. aderna pan : 3 o\ 2 $ Uganda : 11 veins. 



L. leonina bitje : 2 6\ 1 $ Middle Congo, 1 $ Katanga : 11 veins. 



L. loxura : 2 o* Katanga, 1 $ Uganda : 12 veins ; 3 $ Uganda, 11 veins. 



L. eustorgia : 1 $ Katanga : 11 veins. 



I give these figures with some reserve because, when present, vein 8 is very difficult to detect, 

 even when the wing is soaked in alcohol. To be absolutely certain, it is necessary to remove 

 the scales completely by immersing the wing in Eau-de-Javelle, which results in permanent 

 damage to the specimen. However, I do not think I made a mistake in every case, and can 

 only conclude that Lipaphnaeus sometimes has 12, sometimes 11 veins in the fore wing. One 

 interesting fact emerges from the figures, which naturally, are too small to be the basis of safe 

 conclusions : whilst the males are almost equally divided (6 : 5) between 12 and 11 veins, none 

 of the females has more than 11. Lipaphnaeus is much better characterized by its 5" genitalia, 

 in which the dorsal structures sharplv differ from Spindasis. 



Male genitalia {aderna aderna, Text-fig. 143). Uncus subtriangular, deeply divided to form 

 two tapering points ; subunci long, very slender, evenly curved and folded (when in situ) 

 inwardly below the uncus ; tegumen very small, well differentiated from the vinculum ; 

 vinculum narrow dorsally, wider ventrally, with a rounded saccus ; inferior fultura lozenge- 

 shaped, deeply divided distally ; valves oblong, tapering to a point, the upper processes united 

 midway by a narrow band as in Spindasis ; penis elongate, much less massive than in Spindasis, 

 devoid of dorsal protuberance but with a rounded depression midway on dorsal margin, the 

 outer portion tapering to a blunt end ; margins of uncus and apex of valves pilose.
