326 SOUTH- AFRICAN BUTTERFLIES. 
row of five silvery spots, black-edged on both sides, of wbicli the upper- 
most is very mucli the largest ; beyond middle a continuous, wide, sub- 
macular silvery band, with its very irregular inner edge interruptedly 
marked with black ; inner-marginal area dull-silvery, with two small 
black spots before middle, and a black line (longitudinal) between sub- 
median and internal nervures ; three small black spots along costa 
before middle ; hind-marginal border immediately preceded by a series 
of fuscous-edged lunulate spots, of which the second (largest, between 
subcostal nervules) and fifth are silvery, and the rest salmon -red ; 
border itself greyish- silvery, its contained spots creamy-white tinged 
with ochreous-yellow, and ringed (near anal angle very distinctly) with 
black enclosing a very thin line of bluish-silvery ; indenting silvery 
discal band externally, a series of inter-nervular thin brown rays. 
$ Similar, hut 'paUr and duller ; the outer markings fuscous ; spots 
in hind-marginal horder larger. Hind-wing : an irregular transverse 
row of seven spots (sublinear except the subannular large spot on 
costa) extending to below first median nervule. Under side. — As in 
<J, but paler throughout. 
Head tawny above, with four w^hite spots ; palpi tawny above, black 
laterally, white below, — the terminal joint black throughout. Thorax 
tawny above ; collar with a white spot on each side ; below, brown 
with a broad white breast-stripe (longitudinal), and seven or eight 
different- sized white spots on each side; legs whitish. Abdomen tawny 
above ; below with a creamy dark-bordered stripe down the middle. 
A ^ specimen from the Zambesi, in the South- African Museum, has the 
ground-colour darker on botli upper and under surfaces, and the silvery band 
bej^ond middle of hind-wing much narrower and more macular. (It was on a 
Zambesi specimen that Professor Westwood founded his Charaxes Argynnides.) 
Until Colonel Bowker found this curious little Charaxes in KafFraria in 
the year 1862, the only specimen known to me was one presented to the 
British Museum by Sir Andrew Smith. Mrs. Barber also sent the butterfly 
from Highlands, near Grahamstown; and in 1870 I had the pleasure, with 
her, of observing it in some numbers at a spot a few miles from Highlands. 
On the Bashee River Colonel Bowker noted Jahlusa as rare, and keeping 
constantly to particular trees, whence it would chase away other butterflies. 
Both at Uitenhage and at Zwaartwater's Poort I found that Jahlusa delighted 
to settle on the stems and twigs of the Spekboom " [Portulacaria afra), but 
did not avoid those of other trees, and sometimes visited twigs of mere bushes. 
At the latter locality they also continually settled on a low, rough-leaved 
Solanum with dull-purple flowers, sucking at an exudation on its stems and 
(in one instance) at its flowers. ^ When thus engaged they were well hidden, 
the leaves of the Solanum being broad and lying horizontally towards the 
summit of the plant ; and when settled on the white bark of the trees (espe- 
cially on the glossy-white of the Spekboom), their silvery under side rendered 
them very inconspicuous. On the wing the species most resembles Atella 
Plialantha. Its flight, even in the case of the $ , is very slow for a Charaxes, and 
more like that of Pyrameis Cardui. It was in February that I made these obser- 
^ As will be seen elsev/here, the Marquis Antinori in Abyssinia noted the same habit in 
Ch. Candtope (Godt.)
