A. Douhledayi is a near ally of A. CcBcilia. Fab. [Hypatia, Dru.), a well- 
known West- African species, but, as far as the ^ sex is concerned, may readily 
be recognised by its more rufous colour (extending to the terminal half of the 
abdomen), narrower blackish borders, smaller spots, and much less pronounced 
basal blackish ; while on the under side the spots in the hind-marginal black 
border are larger. It has no closely-related known South- African form, the 
least distant, A. Steoiohea, Wallengr., having the sexes almost alike, and 
remarkably suffused with black over all the basal region of the fore-wings. The 
5 Doiiblcdaiji bears a superficial resemblance to the $ A. Petrma, Boisd., as 
well as to the reddish-brown form of A. Lycia, Fab. From the former it is at 
once distinguished by its much smaller and more separate spots, and much 
narrower and less conspicuous subapical white bar of the fore-wings, and from 
the latter by its possession of a black border to the hind-wings. The variety 
A. (NelusJca, Oberth.) decidedly approaches in character the closely-allied A. 
Caldarena, Hewits., in which both sexes possess a very broad black tip to the 
fore-wing. 
From January to April 1867 I found this butterfly abundant near D'Urban, 
Port Natal, and the late Mr. M'Ken and Colonel Bowker have since sent many 
specimens from that neighbourhood to the South-African Museum. It is a 
very slow flyer, cbiefly frequenting wooded spots. I took the sexes paired on 
March 24th, and Colonel Bowker has since 1877 sent me several pairs captured 
in coj[)uld, ;
