. Cassell's natural history. Animals; Animal behavior. TUE kind of paw, quite useless for walkiiig, and hence some writers have called them Brush-footed Butterflies. The pupa is generally suspended freely by tlie tail. The caterpillars differ in structure, .some being hairy or spiny, others furnished with long fleshy filaments, and others again ai-e almost naked, with a forked tail. The first group, the Danalnce, is almost confined to the tropics. Most of the species of Danais iiiliabit the Old World, though a few are met with in America, one species being abundant over almost the whole of that Continent. They are large broad-winged Butter- ilies, generally either of a warm reddish-tawny colour, with blackish borders, or brownish-black, the centre of the wings being green, divided by the veins. The only European species {Danais chrysip- pus) is found in Greece, but is also one of the commonest Butterflies in the East Indies and Africa. It is reddish-tawny, with black borders dotted with white, and the tip of the fore wings is broadly black, and marked with a band of large white connected spots. There are also four black spots in the middle of the hind wings. There is scarcely any Butterfly which is more interesting than this insect, as it illustrates some of the most remarkable pro- blems of insect life in a pre-eminent degree. The Danaince are rarely attacked by birds. Their integu- ments are exceedingly tough, and most of them possess the power of protruding two strongly-smelling jjrocesses from the abdomen. But it would scarcely be imagined beforehand that the colours and markings of a species thus pro- tected would be repeated, with more or less accuracy, in six or eight other Butterflies and Moths, bearing a much closer resemblance l, danais chrvsippus to the species which they thus " mimic " than to any of their own allies. What is still more strange is that in several of these instances it is the female only which resembles the species &qu
