Gu^rin's figures (Joe. cit.) of an Ab3"ssiniau specimen represent the 

 fore-wing as slightly clouded with fuscous and the hind-wing as more 

 inclining to yellow than to red ; so that the individual in question, 

 though nearer Enccdon proper, appears to have varied a little in the 

 direction of the Lycia form. The type of the latter, in the Banksian 

 Collection of the British Museum, is a good-sized whitish ^, with the 

 fore-wing thickly suffused with fuscous, and is ticketed " Sierra 

 Leone." 



The Natalian ^ s of the Lycia form ai-e yellower than those usually 

 brought from the West- African Coast. " Two of the latter, in the South- 

 African Museum, which were taken by the late D. G. Rutherford 

 at Camaroons, are much smaller than usual, expanding only i in. 

 10 lin. 



I have not been able to separate IMadagascar specimens (jS(janziin, Boisd.) 

 from the true Lycia, though I find in them a tendency to confluence of some of 

 the spots in the fore-wing (particularly tlie two in and at tlie extremity of the 

 discoidal cell).^ In the unusually small individual figured by Boisduval (loc. 

 cit.), this tendency is carried further, and, with the partial failure of the inner 

 part of the subapical fuscous, gives the look of a distinct form. 



A. Encedon has no very near allies, but presents points of affinity to 

 A. Pefrcea, Boisd., in one direction, and to A. liahira, Boisd., and A. A^iacreon, 

 Trim., in another. It may at once be known from all its South- African con- 

 geners as the only Acrsea with a white subapical bar of the fore-wing in both 

 sexes. 



This very well-known and widely-ranging species is abundant on the coast 

 of Natal, chiefly frequenting wooded places, and is also met with inland as far 

 as Pietermaritzburg, where I found it in 1867. The pale variety seemed as 

 common as the rufous type-form, and I took numerous examples of both sexes 

 at D'Urban, Verulam, and Pietermaritzburg. The paired sexes of Encedon 

 (typical) Avere sent to me from D'Urban by Colonel Bowker in 1878. The 

 same gentleman, in 1879, forwarded me two males, one of the typical and the 

 other of the pale form, which had been taken at Fort Chelmsford, while fight- 

 ing together on the ground with great pertinacity, by Captain H. C. Harford 

 of the 99tli Regiment. The typical Encedon is also known to me to occur at 

 King William's Town in the Cape Colony, at Delagoa Bay, and in Damara- 

 land; while Aurivillius (loc. cit.) notes its inhabiting Guinea in company with 

 tlie Lycia form. 



^ These two spots are united by a fuscous ray in three Natalian examples, one of the 

 rufous and two of the Lycia form.
