154 SOUTH- AFEICAN BUTTERFLIES. 



inner margin ; an irregular black basal marking enclosing a wkite 

 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-iving : 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-tving : 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 ohlique bar beyond discoidal cell, which 

 are separate from each other, and only three or four in number ; in 

 hind-wing the hind-marginal border broader. Under side. — Hind- 

 wing : 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 differences like those presented by $. Hind-iving : 

 basal suffusion and hind-marginal border much broader and darker. 

 Jlab. — Eastern extremity of Cape Colony, Basutoland, and Angola. 



This rather sombre-coloured Acrcea is allied to A. Cecilia, Yah., 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. 



Stenobea is also closely related to A. Natalica, Boisd., and may indeed be 

 regarded as linking that species and Ccecilia. 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 ; Avant 

 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. 



In 1872 ^Ir. "W. Morant sent me the paired sexes of A. Stenobea, captured 

 at Hebron, on the Vaal Eiver, Griqualand West.
