XVI. — On some African Butterflies hitherto referred to the 

 Genus lolaus, with Descriptions of new Species. By 

 Hamilton H. Druce, F.E.S. 



I FIND that very little notice has been taken hy various 

 writers on this "-roup of butterflies of the arrangement of the 

 subcostal nervules. As I have been able to carefully 

 examine nearly all the species, and find that there are con- 

 siderable differences amongst them, it becomes necessary that 

 they should be divided into several genera, which I propose 

 to do as follows : — 



Ke?/ to the Genera [formerly lolaus).
