66. Eletica stuhlmanni Kolbe, Stett. Ent. Zeit., LV, p. 183. 



Chiyaka, November, 1907, three specimens (Wellman). Brought 

 to me by my servant. 



Described from Lake Albert Nyanza. It is probable that my 

 specimens represent a new form, very closely allied to stuhlmanni, 

 but the specimeas are in such bad condition that I cannot separate 

 them from Kolbe's species, without further material. 



The type of stuhlmanni, is in Berlin, Konigliches Museum.
