Description
Excerpt from South-African Butterflies, Vol. 3: A Monograph of the Extra-Tropical Species
Imago. - First pair of legs in both sexes as fully developed in all respects as the other pairs. Discoidal cell always closed in both fore and hind wings.
Larva. - In Pierinœ cylindrical, tapering to each extremity, without processes or other appendages, usually with very short pubescence: in Papilioninœ stouter, often thickened towards anterior extremity, smooth, or with long tubercular prominences, possessing on second (prothoracic) segment an exsertible strongly-scented forked tentacle.
Pupa. - More or less angulated; head singly pointed in Pierinœ, bifid in Papilioninœ; attached erectly, obliquely, or horizontally, by the tail and by a girth round the middle.
The two Sub-Families, Pierinœ and Papilioninœ, which compose this Family, are readily distinguishable by the characters of the perfect insect. The Pierinœ have in the fore-wings the first disco-cellular nervule either obsolete or very short; the third disco-cellular and lower radial nervules disposed as in other butterflies; the branches of the sub-costal nervure varying in number from three to five; no internomedian nervule; and the internal nervure rarely present, and then very short and slender, and running into the submedian nervure: in the hind-wings the inner margins are convex, forming a groove or channel beneath the abdomen, and the internal nervure is long and strong; the precostal nervure is always simple. The palpi are of moderate size and porrected; the antennæ have a straight club. The legs are short, and there is no appendage to the tibia of the first pair; the tarsal claws are bifid, and usually provided with pulvilli and paronychia.
