Mr. H. H. Druce on some African DtUterJlies. 139 



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 veiy little notice has been taken by various 

 writers on this group 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 : — 



Kei/ to the Genera {formerly lolaus). 



lOLAUS. 



S ? • Four subcostal nervules to primaries. 



c? . Inner margin of primaries below witb a short tuft of hair and 

 a scaly patch over ; a seal}' patch near base of secondiiries 

 above. Antenna} rather long and slender. 



Epameha. 



S $ . Four subcostal nervules to primaries. 



cJ. Inner margin of primaries below with a short tuft of hair; a 

 scaly patch near base of secondaries above. Antenn;e short 

 and thick. 



5 . Scaly patch very large and shining. Antennae longer and 

 more slender. 



SUKIDION. 



(S . Four subcostal nervules to primaries : tuft of hair on inner 

 margin of primaries below extending along to outer angle. 

 No scaly patch on secondaries. Head large ; antennae long 

 and rather stout. 



AnGIOLAUS. 



(5 . Five subcostal nervules to primaries ; tuft of hair on inner 

 margin of primaries below and scaly patch near base on 

 secondaries above. 



5 . Four subcostal nervules to primaries. 



Tanuetheiea. 



Costa of fore wing much arched, outer margin rounded, tails long and 

 broad. 



(^ . Five subcostal nervules to primaries; tuft of hair on inner 

 margin of primaries below and scaly patch near base on secon- 

 daries above. 



5 . Four subcostal nervules to primaries.
