SOUTH-AFEICAN BUTTERFLIES. 
inner margin ; an irregular black basal marking enclosing a white 
spot ; a small black spot on costa, near base, and a large elongate one 
a little farther from base ; hind-marginal border enclosing seven large 
whitish sub-trigonate spots. 
$ Darker ; the basal suffusion in fore-wing ill-defined, gradually 
shading off into brownish. Hind-wing : hind-marginal border broader, 
its inner edge not regularly denticulated but rather suffused ; a con- 
spicuous white cloud on lower part of disc, covering median nervules 
about their origin, and extending to submedian nervure. Under side. 
— Fore-wing : apical whitish developed over some space ; blackish spots 
more distinct. 
Var. a. $ and $ (Lygus, Druce). 
^ Basal blackish suffusion less pronounced in fore-wing ; black 
spots smaller, especially those of ohliqice beer heyond diseoidal cell, which 
lire separate from each other, and only three or four in number ; in 
hind-wing the hind-marginal border broader. Under side. — Hind- 
luing : ground-colour duller, more rufous ; the spots in the hind- 
marginal border much smaller, so as to occupy only the outer part of 
the border. 
$ General difierences like those presented by Hind-wing : 
basal suffusion and hind-marginal border much broader and darker.

This rather sombre-coloured Acrcea is allied to A. Cecilia, Fab., but is easily 
distinguished by its yellow-ochreous ground-colour and much wider dark basal 
suffusion, while the hind-marginal border is narrower, and there are fewer 
discal spots. The white cloud on the hind-wing of the $ , though variable in 
extent, seems invariably present. The reddish-pink clouding on the under 
side of the hind-wing is remarkably developed in some fine examples collected 
by Mr. F. C. Selous on the Upper Limpopo, especially in the ^ s. 
Stenohea is also closely related to A. Natalica, Boisd., and may indeed be 
regarded as linking that species and Coecilia. Its distinctive characters are 
smaller size ; paler, clearer ground-colour (especially in hind-wing) ; wider, 
more suffused basal, but very much narrower apical, black in fore-wing ; want 
in the same wing of the outer discal series of spots ; and more imperfect discal 
row of spots, and very much narrower and unsuffused hind-marginal border, of 
hind-wing.
