discoidal cell ; a broad, oblique, wliite stripe beyond middle, not reach- 
ing to costa or to liind-margin, crossed by three nervules ; a large, 
somewhat semicircular white blotch occupies nearly the whole of 
inner margin, rising as far as median nervure, but not quite to its 
second nervule. Hind-iuing : iridescent white ; basal portion blackish ; 
a broad black band along hind- margin, wider and suffused with brownish 
about anal angle, radiating in streaks hehveen nervules. Under side. 
— Paler : similar in pattern. Fore-wing : a small white spot at base ; 
another on costa, near base ; a third in discoidal cell, hefore the white 
streak ; costa tinged with ochreous-brown, as well as apical portion 
beyond oblique white band. Hind-iving : hind-marginal band coloured 
with ochreous-brown, very much narrower than on upper side, radiating 
very distinctly between nervules ; a conspicuous white spot on narrow 
basal black. On hoth ivings are the traces of a double row of minute 
whitish lunules along hind-margin, and in liind-ioing a submarginal 
series of rather indistinct white minute spots in fuscous rings situated 
on the inter-nervular blackish rays. 
$ Similar to the hut all the ivhite markings larger^ especially 
the cellular streak and the subapical stripe. Fore-umig : a small spot 
in discoidal cell corresponding to that of the under side. Under 
SIDE. — Hind-marginal lunules more pronounced, — those of the fore- 
wing tinged with blue. 
This is a very near ally of E. Anthedon, Donbl., a native of "Western 
Africa, being indeed its Southern representative. The principal differences pre- 
sented by ]Vahlbergi are (i) its considerably larger size \AntJLedon not appearing 
to exceed 3 in. 8 lin. in expanse of wings), and (2) its larger white markings, 
especially as regards the liind-wing, where in Anthedon tlie white extends to 
hut little beyond the middle. These differences exactly correspond to those 
which distinguish the South-African Amaiwis duminicanus, Trim., from the 
West-African A. Niavius (Linn.) ; and E. Wahlhergi is as accurate a niimicker 
of the former as E. Anthedon is of the latter species of Aviauris. 
I met with this very conspicuous butterfly at D'Urban, ISTatal, in February, 
March, April, and June ; but it was always scarce, and I captured four speci- 
mens only. It is a woodland insect, and is fond of floating about low trees, 
quite in the manner of the Amauris it so closely resembles. The imitation is 
so exact, that, prior to actual examination of a captured individual, I found it 
impossible to tell whether I was taking the Euralia or the Amauris. The late 
j\rr. M'Ken sent several specimens to the South-African Museum, all taken in 
the D'Urban Botanic Gardens ; and Colonel Eowker lias since forwarded a few 
from the same neighbourhood. Of the latter, one remarkably small ^ is only 
3 in. I lin. in expanse of wings. I have recorded (T?yc7^s. Ent. Sac. Land., 1873, 
p. 107, note) the capture by Captain H. C. Harford of a^ 9 ^kis butterfly 
paired with a ^ E. mima, Trim. Notwithstanding tlie very different pattern 
and colouring of the wings, the two forms are very closely related.
