African Species of the Genus Acraca. 21 



(/) Basal spots of h.-w. underside are more or less confluent and 

 enclose or tend to enclose pale spots. (Some examples of 

 tm-na are thus but the species usually comes under 



Section VI.) V 



Basal spots of h.-w. underside are not coniiuent . . (f/) 



{(j) Discal spot in lb of f.-w. is much nearer margin than that in 



2 so that a line joining their centres would pass through 



cell* Vt 



Discal spot in lb of f.-w. is beneath or nearly beneath that in 

 2 so that a line joining their centres would pass outside 



cell . VII 



Qi) Internervular rays not connected with hind margin or at 



least reduced to a fine point at margin ... IX 



Internervular rays connected with hind margin and not 



narrower there than elsewhere X

rahbaiae rahhaiae (43) 

 II. -w. thinly scaled with whitish ochreous

 mind that i/ie? unimaculata cienerallyhas no spots on either tving, and 

 that inda,mii and cuvaf/ie red (f the ^ isusiudly replaced hij yellonnsh 

 or whitish.

 H.-w. margin transparent, or partly transparent, narrow,

 though owing to variability the discal spots in juauy examplei^
