In order to give a clear idea of the nature of these cases of mimicry, it is nee ssary to 

 consider them separately. I will therefore describe them seriatim as concisely as pos- 

 sible, only premising that, as regards Tropical Africa, so little is on record respecting the 



it 



ge of individual species or their variation, to say nothing of habits and stations, that 

 s at present impossible to treat satisfactorily of the instances occurring in that 



immense tract of country

This species is rather widely spread in tropical Western Africa, examples harm 

 received from Sierra Leone, Ashanti, the Gaboon, and Angola (in about 8° S. lat

broad 



'ly related to D. Egialea, Cram., but is larger, and maj 



ecognized by the 



central white band of the fore wings (which extends below the first median 



vule), by the more 



ular subapical white bar of the 



same wings, and 



by the 



smaller and whiter basal space in the hind wings 



The Gaboon examples form a variety 



in which the pale basal patch in the hind wings is either reduced to a small spot or 

 altogether absent. In Angola this Danais is accompanied by a Diadema (which also 

 inhabits Congo) that very closely imitates it, differing from Diadema dubia, its nearest 

 %*, precisely as Danais Damocles differs from its congener Egialea.
