“ Nature has so admirably disguised this insect in the external form of that tribe of butterflys which she intends it to represent, that it was only upon looking to its anatomical construction, that we discovered it was a type of the true Papilionæ, and not of the Erycinæ. The construction of the anterior feet, of the head and palpi, and of the antennæ, all which are here represented, magnified, places this fact beyond doubt, and leaves us nothing to desire but a knowledge of its caterpillar and chrysalis, and of the direction of the wings when the species is at rest. ”
