New or little-known African Butterflies. 3 
forewing, the 4th being smallest and farthest from base, and the Ist 
and 6th nearest to base ; hindmarginal border of even and moderate 
width (its inner edge very slightly irregular), enclosing seven small 
but rather conspicuous rounded white spots, of which the last, at 
anal angle, is geminate. UNDERSIDE.—Hindwing and broad apical 
bar of forewing white ; disco-cellular and discal spots as on upper- 
side. Forewing: in discoidal cell an additional small sub-basal 
black spot, preceded by a black dot ; black on inner side of hind- 
marginal border thin and diffuse, and partly effaced by radiation of 
the apical white along the nervules as far as 2nd median. Hind- 
wing : on costa at base a fulvous-ochreous spot; bases of nervures 
clouded with black ; the following additional black spots, vid. :—a 
small one on costa very near base ; a large, elongate, sub-basal one 
between costal and subcostal nervures; a similar large elongate 
one between median and submedian nervures ; and two small spots 
below submedian nervure ; on the right side only, there is a very 
small spot near base in discoidal cell ; an eighth spot in discal series, 
below submedian nervure ; white spots in hindmarginal black border 
very much larger than on upperside, and outwardly bounded by a 
merely linear black edging. 
Palpi ochre-yellow ; abdomen pale dull creamy-ochreous, clouded. 
with blackish in its basal part. 
From its nearest ally, A. chilo, Godm., ~, this remark- 
able species differs in its (1), much reduced black mark- 
ings throughout—especially, on the upperside, the sub- 
basal disco-cellular spot in the forewing, and the basal 
clouding in the hindwing; (2), small white and rounded 
spots—as in A. violarum, Boisd—in the hindmarginal 
black border of the hindwing on the upperside, instead of 
large dull-reddish crescentic ones; (3), more ochreous 
eround-colour of upperside, in tint like that of A. anacreon, 
Trim. ; and (4), much purer white of hindwing and apex 
of forewing on underside. Another curious feature in 
this Acrva is that, although clearly belonging to the zetes 
and acara group and a close ally of A. chilo and A. bar- 
beri, Trim., yet the hindmargin of the forewings is not 
incurved about the median nervules as in that group, 
but is even and almost straight, as in A. violarwm and 
A. nohara, Boisd. 
The only example known to me is in the Oxford Uni- 
versity Museum, where Prof. Poulton most kindly brought 
it to my notice; it bears a ticket “Coll. Watson, 1871,” 
but unfortunately no record of locality. It is unquestion-
