of Danais appear to exist side by side at Sierra Leone and in Ashanti; and it is probabl 

 that the mimiekers of Damocles will eventually be found in tbose localities from wind

Danais Ei/ialca, Pap. Exot. pi. 192. fig. D. 



This Danais has apparently a less extensive range than D. Damocles, inhabiting 

 Sierra Leone, Cape Palmas, and Ashanti. It is most exactly copied by Diadema dubia, 

 i } ;il. de Beany., the only noticeable difference being that the Diadema has three or four 



additional dots near the hind margin of the hind wings. There are specimens of this 

 Diadema in the British Museum, from Sierra Leone and Ashanti ; and in Mr. Hewitson's 

 collection, from Calabar. Palisot de Beauvois records it as a native of Oware and Benin, 

 the latter district being situated between Ashanti and Calabar.

D. Echeria is a widely-spread and abundant butterfly throughout the wooded parts of 

 Soutli Africa, where it takes the place of its tropical ally, D. Egialea. Like the latter, 

 't has an exact imitation in a Diadema, which, though nearly allied to D. dubia, appears 

 to lie distinct*. But Echeria has no less than three other imitators in the genus Fapilio, 

 ' ' two more accurate mimiekers— P. echerioides, Trimen, ? , and P. Merope, Cram., ? 

 C /, Stoll)— being females of very dissimilar males, and the third a variety of 



. Leomdas, Fab., which seems only to occur in South Africa beyond the tropic, and

Inch the pale markings are almost or wholly devoid of the green or greenish colour a
