ACRiEIX/E. 
This Acrcea stands between A. Acam, Hewitson, and A. C/iilo, 
Godman (Froc. Zool. Soc. Lond., 1880, p. 184, pi. xix. figs. 4, 5), a 
native of Abyssinia. It differs from the former in its much less developed 
hlacJc marldngs (particularly the basal black of both wings, and the 
subapical bar and apical border of the fore-wing), and in the apical 
yelloiu-ochreous of the fore-iving being very much fainter. In the female 
these differences are as marked as in the male, but the former is also 
distinguished by the remarkable transparency of the fore- wing. From 
A. Chilo, on the contrary, A. Barleri is in both sexes distinguishable 
by its stronger black markings (with the exception of the inner edge 
of the fuscous hind- marginal border of the fore-wing in the male and 
of both wings in the female, which in A . Chilo is unbroken near apex 
of fore-wing), and in the female by the much less transparency of the 
fore-wing. The under-side markings and colouring of A. Barleri agree 
entirely with those of A. Acara, except that the former are smaller. 
I have named this butterfly after its discoverer, Mr. H. Barber, who cap- 
tured the two males and the female here described in the Transvaal country 
during the year 1873. Mr. Barber collected a number of species in that region, 
but did not note localities further than stating that all were taken to the north 
of Pretoria. 
To this species, I consider, should be referred two butterflies received at 
the South-African Museum, viz., a male taken on the Vaal River by Colonel 
J. H. Bowker, and a female forwarded from some part of the Transvaal by Mr. 
D. Arnot. These examples are clearly referable to one and the same variation, 
both having the apical yellow-ochreous of fore-wing more pronounced, while 
the interior fuscous edging of the hind-marginal border is almost obsolete. In 
the male this last-named character extends in a less marked degree to the hind- 
wing, while in the female the peculiar transparency is not noticeable, the 
wings being quite as opaque as in ordinary females of A. Acara.
