SOUTH-AFRICAI^ BUTTEKFLIES. 
blackish. Fringe of both, wings as in ^, perhaps more distinctly marked 
with whitish. Under side. — Quite similar to that of $^ but more dis- 
tinctly marked ; the hind-iuing a little more hrotonish in tint. 
Larva. — Dull violaceous-grey on back, margined laterally by a 
broad fuscous stripe, interrupted on segmental incisions ; below the 
fuscous stripe a series of elongate yellowish markings on a ground- 
colour slightly darker than that of the back ; below this the sides are 
brownish-ochreous. Spines black. Head black, rather bristly, white- 
spotted in front, with a pair of short divergent horns on summit. 
Legs and pro-legs dull violaceous-grey. 
Described from a drawing by Mrs. Barber, reproduced in Plate I. 
Jig. 4. Mrs. Barber informed me that the food-plant of this larva is a 
purple-flowered species of Barter ia (Ord. Acanthacece). 
This butterfly is very nearly allied to the well-known Asiatic species /. 
CEnone, Fab., of which it is indeed the African representative. The much 
more limited area of oclire-ijelloio in both wings, and the larger, more viola-' 
ceous, rounder blue spot in the hind-wings, on the upper side, readily distinguish 
Cehrene ; its under side is universally greyer and less ochreous in tint. In 
the ^ the fore-iving has the ochre-yellow marking paler centrally, not occu- 
pying basal area, but commencing at about the middle of the cell, deeply 
indented by black in costa beyond middle, but not by any disco-cellular ter- 
minal streak. The Innd-iving has the ochre-yellow patch narrower on the 
inner margin, not extending so far in the direction of the costa ; the dark 
hind-marginal lunular striae, excepting that at the anal angle, are scarcely 
traceable, and the basal blue spot is not flattened superiorly. On the under 
side, the fore-iuing has the terminal disco-cellular streak thinner and fainter ; 
while the liind-icing has the transverse striae fainter, subdentate instead of 
sharply crenelate (especially the subbasal and submarginal ones). In the $ 
the fore-ioing has the ochre-yellow patch still smaller ; but the Imid-iviiig has it 
larger than in the ^ , while there is a single well-marked hind-marginal lunulate 
streak instead of the two (or sometimes three) parallel streaks found in (Enone. 
The late Mr. F. Walker gives (jSTewman's Entomologist, 1870, p. 51) Mada- 
gascar as one of the localities of CEnone, but judging from six male specimens 
from Murundava, on the west coast of that island, in the collection of the South- 
African Museum, the Malagasy form, though very near Cehreue, is quite distinct 
both from the latter and CEnone. As compared with Cehreue, it presents the 
following points of difference, viz., in the fore-wing : (i) The ochre-yellow patch 
is differently shaped and situated, being vertically deeper, with its inner edge 
considerably farther from base and much less oblique ; (2) in the discoidal 
cell, thus left almost wholly black, there are two metallic-blue striae, of which 
the inner one is usually indistinct ; (3) the subapical pale-yellow mark is very 
small, remote from ochre-yellow patch, and divided transversely. In the hind- 
wing (4) the blue spot is larger, more metallic, not violaceous, less rounded, 
being prolonged outwardly on radial nervule ; and (5) the ochre-yellow patch 
is much less rounded, its inner edge being farther from base, and it is also 
marked externally by two slightly darker streaks running parallel to hind- 
margin. On the under side, in the fore-wing, (6) the black-edged cellular 
striae are strongly defined, that at end of cell being double like the others, 
which are distinctly bluish; and in the hind-wing (7) the colouring beyond 
middle is tinged with ferruginous; while (8) the median transverse line is 
much more irregular and dentated, and bounded externally by a dark ashy-grey 
stripe, broadest on costa. 
Should this form be undescribed, I propose that it should be named Junonia 
Paris.
