232 upwards of four inches in length, occur in South America. The eggs of the Mantidæ, which are very numerous, are enveloped when first laid in a soft substance, which, by exposure to the air, soon acquires the consistency of parchment. They are disposed, as in the family last described, in two rows; are of an elongated form and yellow colour. The packet is attached by an adhesive gum to the stalk of a plant. As a generic designation, the term is now limited to such members of the family as have the antennæ simple, head without an angular projection in front, eyes hemispherical, anterior legs long and falciform, the others slender and without spines. Many of them are of considerable size, and with a very few exceptions, extra-European.
