BOOK I.
PART I.
The Caterpillars, described in this Book, are such as produce Moths; of which, as there is a great Variety, ’twas thought proper to range them under the following Heads or Chapters.
CHAP. I.
The Caterpillars belonging to this Chapter have six Hooks or Claws before, eight Feet in the middle, and some have, and some have not two Holders behind. Their Bodies are composed of twelve circular Joints, or Rings, conjoined by a common Membrane, which they are capable of contracting or expanding. When they would move along, they dilate the muscular Skin that separates the first Ring from the next; they advance the first Ring to a certain Distance, and then, by contracting and expanding the Skin of that Part, they move the second Ring: the same Method moves the Third, and so the whole Body marches in Succession: the Motion of their Feet and Claws corresponding with and assisting the progressive Motion of the Rings.

The Caterpillars under this Head may likewise be divided into three Classes:
- I. Naked or without Hair.
- II. Having little Hair.
- III. Having much Hair.
The First Class, or the NAKED and without Hair, may be subdivided in the following Manner.
