XLI. — A few Synonymical Notes upon African Lepidoptera. 

 By W. J. Holland, Ph.D., F.E.S. 



The seventeenth livraison of Mons. Charles Oberthlir's 

 splendid ' Etudes d'Entomologie ' is before me. I am glad 

 to see the discussion on p. 28 in regard to Drurj's Acrcea 

 cynthius. The identification of this species and the species 

 which have borne the names serena, Fabr., bonasia, Fabr., 

 and epom'na, Cram., has led to much difficulty in the minds 

 of the students of African Lepidoptera. Having recently 

 had occasion to work out the subject with all the literature 

 pertaining to it before me, and at the same time with long- 

 series of the species in question at hand for study and 

 reference, it is a pleasure to me to see that so eminent an 

 authority as Mons. Oberthiir has practically attained the same 

 results in his investigations as those at which I have myself 

 arrived. Mons. Oberthiir expresses some doubt as to the cor- 

 rectness of his decision ; but that it is absolutely correct seems 

 to me to be beyond question. 



It is worthy of note that the species which he figures with 

 some hesitation as Acrcea cynthius, Drury, has for some years 

 past been sold as Acra^a bonasia, Fabr., b}' Dr. Staudinger, 

 and thus stands labelled in many collections. Dr. Staudinger 

 was undoubtedly led to this determination by the identifica- 

 tion of ^. bonasia, Fabr., with A. cynthius, Drury, by Kirby
