Katal through Kaffraria into the eastern districts of Cape Colony ; 
Lyoeus and Cenea descend as far southward and westward as the 
Knysna district ; and JDemolcus alone penetrates to the Cape peninsula 
itself. The Transvaal has not hitherto been much worked by collec- 
tors, but the following seven species have been received by me from 
that great tract of country, viz. : Gorinneus, Constantimis, O^jhidice^olia- 
lus, Bemoleus, Euphranor, Lyceus^ and EchcrioiclGs. 
The borders of woods are the chief resort of this genus, and it is 
there that all the South-African species are to be found, — the 
widely-spread P. Demoleus, however, occurring freely also in open 
country. The $ s are strong fliers ; P, Lymes often soars over lofty 
trees ; and the rare Eiiphranor appears to have habitually rather a high 
flight. Policeiies, like the rest of the true " Swallow-Tails," is remark- 
ably swift, but is fond of settling to drink at muddy places. P. Cenea 
and Ophidicephalus} and probably others, have the habit of following 
for hours in the forenoon a set course through the woods, apparently 
in rivalry and in search of the females, the latter being comparatively 
slow and inactive, and more commonly taking wing in the afternoon. On 
their frequent visits to flowers, the species of Papilio keep their wings 
in rapid vibration, not closing them while feeding, but appearing to be 
constantly on the alert to be off again. When basking in the sun on 
leaves, they have, however, the habit of holding the wings horizontally 
or slightly deflected, with the hind-wings half hidden by the over- 
lapping fore-wings. This posture is a specially favourite one with the 
African P. Demoleus.
