The chrysalids most nearly resemble those of Papilio but have the angulations still more prominent, the ventral bend bolder and the wing-cases more tumid. Their color is brown of various shades, often highly tinged with greenish and always streaked boldly and delicately with EXCURSUS LI.âSOUTHEHN INVADERS.

Immediately upon the close of the glacial epoch, there was a movement of butterflies from the south northward, following by slow steps the retreat of the ice, some at nearer, some at greater distance. It would appear from sundry facts as if this movement were still going on ; at any rate we find upon the southern shores of New England a number of butterflies belong- ing more properly to the extreme south which are struggling to maintain an existence on our shores, apparently unable to make any further considerable advance to the northward. Such arc Junonia coenia, Euptoieta claudia, Eurema lisa, Anthocharis gcnutia, Achalarus lycidas, and perhaps one or two others.
