378 SOUTH-AFRICAISr BUTTERFLIES. 
very much paler, and with a glossier surface ; spots of hind-wing as ' 
on upper side. 
$ Beddish colouring ivanting ; fore-iving with a slight tinge of 
hroiunish-ijcllow {chiefly along nervures) over inner hcdf ; hind-wing dull- 
whitish. Hind-ioing : basal and discal spots reduced in size, — the 
basal disco-cellular spot and the first (and sometimes also the second) 
spot of the discal series obsolete ; submarginal hastate spots consider- 
ably enlarged and lengthened, the spots bounding these externally ochre- 
yellow ; hind-marginal fuscous-grey edging broader, diffused. Under 
SIDE. — Almost colourless ; only submarginal black spots of hind-wing 
well marked. 
This species is a very near ally of A. Banavalona, Boisd.,"^ a native 
of Madagascar. It differs from the latter, as far as the $ is concerned, 
in having the red area much paler and yellower, and in the fore- wings 
of very much greater extent ; in both sexes there is no sub-basal black 
spot just below costal nervure, the submarginal black spots of the 
hind-wings are much larger, and the adjoining hind-marginal rufous 
spots of a much duller tint, while the spots of the discal series are 
considerably smaller, especially in the which entirely lacks the 
large and conspicuous first (costal) spot of the $ Banavalona? 
The curious arrangement of the hastate submarginal black spots of 
the hind-wings, with their externally adherent reddish spots interrupting 
the actual grey edging of the hind-margin, readily distinguishes Mache- 
quena from all other known South- African Acrcea^. In tint and general 
aspect the $ is not unlike A. Ncohule, Doubl., but the absence of mark- 
ings in the fore-wings, and black, laterally ochreous-spotted (instead of 
wholly ochreous) terminal half of the abdomen above, at once mark it 
as a different species. The spotless fore-wings recur in some examples 
of the variable A. Cerasa, Hewits., but the latter has no submarginal 
spots at all in the hind-wings. 
Mrs. Monteiro discovered this Acrma at Delagoa Bay early in the 
year 1886, and sent me a rough sketch of it in March, and specimens 
later on. She met with a good many examples of both sexes, but did 
not note anything peculiar in the habits of the species.

2 C. Ward in Part II. of his African Lepidoptera, p. 9, states that he had recently 
(1874) received pairs taken in copula of S and ? Banavalona, " in no way differing" (that 
is, the 9 agreeing with Boisduval's Banavalona S ), and of the ? Banavalona, Boisd., " with 
a 6 only differing in being rather smaller ; " and he on this account separates the latter 
under the name of A. Manandaza. [His description here is identical with that previously 
published in the Entom. Monthly Mag., 1872, ix. p. 147.] 
The occurrence of a red-tinted ? resembling the S is accordant with several similar 
cases in the same genus ; but I incline to the belief (in the absence, however, of the speci- 
mens with which Mr. Ward dealt) that some error was made in respect to the alleged pair 
in which the $ only differed in size from the pale ? . In Ward's figures {op. cit., pi. vii. ff. 
I, 2) the larger " ? " has a good deal of reddish suffusion in the hind- wings, while in the 
smaller " (5 this is quite absent.
