hitherto referred to the Genus lolaus. 143 



collection, and is the only one I have seen. Notwithstanding 

 that Hewitson states that J\Ir. Diuce was unable to ascertain 

 its habitat, it has a written label " Gaboon," whence I think 

 there is not much doubt that it came. 



Akgiolaus, gen. nov. 



Allied to lolaus^ but with an additional subcostal nervulc 

 in male bifurcating from the fourth near the apex ; female 

 with four subcostal nervules. Antenna thicker and more 

 gradually clavate. Terminal joint of palpi shorter.

Mr. Trimen (S. Afr. Butt. p. 129) gives a long list of 

 localities for this species.

This species appears to take the place of A. silas in East 

 Africa. The upper crimson spot in hind wing of female is 

 wanting in all the specimens I have seen. It is the var. A of 

 Mr. Trimen (S. Afr. Butt. ii. p. 128) and is not allied to /.
