SYSTEMATIC ARRANGEMENT. 
upwards of four inches in length, occur in South 
America. 
The eggs of the Mantidae, which are very numer- 
ous, are enveloped when first laid in a soft substance, 
which, by exposure to the air, soon acquires the con- 
sistency 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 Mantis is now 
limited to such members of the family as have the 
antennae 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.
