fulvous-oclireous scaling. Fore-iuing : cliscal area wliitisli (except in 
the most dusky individuals on upper side). Hind - wing : bind-marginal 
border quite linear, not suffused. 
^ Much paler, cdmost wldte (espcK^icdhj in forc-wing, winch is cdmost 
transparent, ctnd with very narroiv hascd and scarcely any disced, fuscous 
suffusion), UnDee side. — As in but hind-wing and apical area of 
fore- wing much paler, in some specimens approaching white. 
AherrJ ^. — Fore-wing entirely pale dull brownish-red, luanting 
the apical fuscous and its white hctr (as in the Dorippus form of Danais 
Chrysippus, Linn.) 
Hah. — Zambesi (Coll. Hewitson, 1867). 
Guerin's figures Qoc. cit.) of an Abyssinian 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 Encedon 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 are yellower than those usually 
brought from the West-African Coast. Two of the latter, in the South- 
African Museum, which were taken by tlie late D. G. Eutherford 
at Camaroons, are much smaller than usual, expanding only i in. 
10 lin. 
I have not been able to sepin^ate Madagascar specimens {Suanzini^ Boisd.) 
from the true Lycia, though I find in them a tendency to confluence of some of 
the spots in the fore-wing (particularly the two in and at the 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. Petrcea, Boisd., in one direction, and to A. Ilaldra, Boisd., and A. Anacreon, 
Trim., in another. It may at once be known from all its South- African con- 
geners as the only Acrxa 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) were sent to me from D'Urban by Colonel Bow^ker 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 99th 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 (/oc, cit.) notes its inhabiting Guinea in company witli 
the Lycia form. 
These two spots are united by a fuscous ray in tliree Natalian examples, one of the 
rufous and two of the X?/Ci'a form. - ■ ,
