“ Madam Merian's valuable work on the Insects of Surinam, has furnished us with a figure of the larva; which, unlike that of the European Swallow-tails, is covered with spines: the chrysalis also departs from the usual type of the family, in having the head directed downwards. These facts we have verified by an inspection of the original drawings, of M. Merian, now deposited in the British Museum. These are all important variations in structure, which can only be explained by the natural system. ”
