hitherto referred to the Genus lolaus. 14.'> 



collection, and is the only one I have seen. Notwitlistandini;- 

 that llewitson states tiiat Mr. Druce was unable to ascertain 

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

 tlicre is not much doubt that it came.

 in male bifurcating from the fourth near the apex; female 

 with four subcostal nervulcs, Anteniue thicker and more

This species appears to take the plac&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 /.
