Extract

While making a study of the larvae of certain species of Noctuidae, the writer was impressed by differences observed in the structure of the hypopharynx. A survey of the literature reveals that, though some workers have paid a certain amount of attention to this organ in larval Lepidoptera, the literature on the subject is not extensive.
