Thia study was undertaken with the purpose of gathering more comprehensive information on the larval anatomy of a typical member of the lepidopterous family Papilionidae. Except for investigations dealing with the osmeteria, literature on the general anatomy of this otherwise well known family is very scant. Because of the relatively small number of speci­mens that were available for study, this paper has been limi­ted to a discussion of the external anatomy and of the gross . morphology of the digestive tract, the urinary system, the silk glands, and the mandibular glands. Important papers in which these structures have been described for other families have been listed in the bibliography. The organization of this paper follows to a considerable extent that of Peterson on Protoparce carolina.
