Ex^o. al., ($) I in. 9-10 lin. 
J JVhitey with moderate-sized scarlet-orange apical patch; base of 
hoth wings with a very slight grey irroration. Fore-wing : a minute 
terminal disco-cellular black spot ; inner edge of apical patch very 
oblique, irregularly denticulated, withont any Uachish or dusky scaling^ 
— costal and hind-marginal edge with an extremely narrow border of 
fuscous-grey, from apex downward emitting short nervular rays piercing 
the orange, and ending between second and first median nervules. 
Hind-wing : a hind-marginal series of terminal nervular black dots. 
LENDER SIDE. — Forc-ioing : disco-cellular dot well marked ; apical patch 
creamy-yellowish faintly irrorated and sparingly striolated with grey, 
its inner border tinged with very pale-orange. Hind-iving : creamy- 
whitish, very faintly tinged with pink, sparsely irrorated and striolated 
with grey (rather more closely so near base and on costa a little before 
apex) ; a terminal disco-cellular black dot, very faintly orange-bordered 
inwardly. 
This is a form of which the $ is as yet unknown. The $ is to 
some extent a link between the Eoenina and Achine groups of the 
genus, and may be recognised by the peculiar form and colour of the 
apical patch, with its total want of any inner dark edging, and 
extremely thin and dull costal and outer edging, as well as by the 
complete absence of any trace of fuscous bordering along either the 
inner margin of the fore-wings or the costa of the hind-wings. 
The type of Simplex is a single injured ticketed "D'Urban," in the 
collection of the British Museum. By the kind aid of Mr. C. Aurivillius, I 
was able to compare with it a typical example of his Damarensis, and found 
the two to be unquestionably the same species. A third ^ has reached me 
from Mashunaland near the Lower Zambesi, in a collection made by Mr. F. C. 
Selous. Mr. Aurivillius {loc. cit.) notes the near apparent alliance of this 
butterfly to Antevippe, Boisd., and Zera, Lucas, both from North Tropical 
Africa. These two forms (judging from specimens so named in the collection 
of the British Museum) belong to the Achine group, and do not appear to me 
to be separable as species.
