Excerpt from South-African Butterflies, Vol. 3: A Monograph of the Extra-Tropical SpeciesImago. - 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 Pierinoe cylindrical, tapering to each extremity, without processes or other appendages, usually with very short pubescence: in Papilioninoe 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 Pierinoe, bifid in Papilioninoe, attached erectly, obliquely, or horizontally, by the tail and by a girth round the middle.The two Sub-Families, Pierinoe and Papilioninoe, which compose this Family, are readily distinguishable by the characters of the perfect insect. The Pierinoe 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.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
