border of exceedingly variable development, and their under side has a 
shining dull-greenish tint, with a terminal disco-cellular spot in the 
hind- wings, so that specimens with scarcely any blackish border look 
very like Callidryas Florella. E. Pharis (which I have not had the 
opportunity of examining) is described by Doubleday {op. cit., p. 65) 
as having " the wings nearly as round as the genus Pontia, and of as 
delicate a texture ; the apex of the anterior just touched above with 
black, below varied with brown ; the posterior wings above immaculate, 
below sometimes nearly immaculate, at others varied with large clouds 
of satiny-brown and silvery- white." 
The four species found in South Africa all have a tropical range, 
Argia and Buquetii both inhabiting alike the East and West Coasts, 
while Leda and Cleodora, with an extensive East-African distribution, 
do not appear to have been hitherto recorded from West Africa. They 
are all found on the south-east, Zeda and Argia not spreading farther 
south-westward than the Bashee River, but Cleodora extending to Van 
Staden's River, and Buquetii to Knysna, and even straggling to Cape 
Town. On the wing they are decidedly swift, but constantly check 
their onward flight to visit flowers. 
The larva of P. Cleodora has been found on Camparis Zeyhcri, but 
I have not seen either specimens or drawings of it.

wing : base usually marked very faintly and narrowly with blackish ; 
hind- marginal border varying from very narrow to broad, — wide apically, 
rather abruptly narrowed on third median nervule, and thence either 
tapering to a point or to a narrower or broader termination (in accord- 
ance with the less or greater width of the border) to posterior angle ; 
inner edge very variable and irregular in outline, generally more or 
less denticulate on nervules and excavate between them, — always a 
very marked and conspicuous prominence or projection (rounded, sub- 
acute, or truncate) immediately above third median nervule ; in apical 
extremity of border two spots of the ground-colour, — a small one 
between second and third subcostal nervules, and a larger one (nearer 
apex) between fifth subcostal and upper radial nervules. Hind-wing :
