A. Horta and A. serena, but more continuous ; the spots rose-pink in 
wide black contiguous rings. Median line of under side of abdomen 
tinged with rose-pink ; two spots of the same colour on median line of 
back of thoraxj and one at base of wings. Head ochreous-yellow. 
Plate I. fig. la. 
This pupa appears to be rounder and blunter anteriorly than that 
of A. Horta, and is so much more curved that the dorsal outline is 
strongly convex in a lateral view. 
The above descriptions are made from a coloured drawing executed 
by the late Dr, Seaman in 1 869, exhibiting a lateral view both of 
larva and pupa. 
This very handsome and conspicuous Acrma is the Southern and 
Eastern representative of the abundant and widely-spread A. Zetes 
(Linn.) of Western Africa, and is readily distinguished by the warm 
red and ochreous colouring of the fore-wings, which are suffused 
fuscous-grey in Zetes. 
I only once took this species on the coast of Natal, in the summer of 1867; 
but it is usually pretty common there, numerous specimens having been taken 
near D'Urban by the late Mr, M. J. IM'Ken, Colonel Bowker, and others. At 
Pietermaritzburg, however, at the end of March and beginning of April, I 
found the butterfly abundant, frequenting flowers in most gardens, and as easy 
of capture as A, Horta. 
The late Dr. Seaman and Colonel Bowker alike reported the iarvse as doing 
much damage to passion-flowers in Natal ; but I have not heard what is their 
native food-plant. 
As I have recorded in the Transactions of the Linnean Society (vol. xxvi. 
pp. 517 and 518), A. Acara is the subject of close mimicry by a member of 
the Nymphalince, d-cscribed by Mr. A. G, Butler as Pseudacrcea Trinienii, In 
this very interesting case each sex of the Acrcea is distinctly copied by the 
corresponding sex of the PseudacroeOj, The latter haunts the same localities as 
A. Acara, but is a rare insect.
