FAMILY GRYLLIDE. CRICKETS.

This family is not well worked up for America. Among the South Carolina species we mention only the following :

The members of this family are all so injurious that we shall give as complete a list as possible.

Tryxalis brevipenis Charp.

Opomala punctipennis Serv.

bivittata Serv.

Pyrgomorpha punctipennis Thos.

Opomala varipes Serv.

marginicollis Serv.

Chrysochraon viridis (So., Ill. and Fla.)

Stenobothrus admirabilis Uhl. (D. C. S. Ill.) Stenobothrus Maculipennis Scudd.

The insects of this family are raptatorial, and prey upon other insects. The common South Carolina species is Mantis carolina Linn., commonly known as the "Rear-horse." It is common all through the South, but was originally described from Carolina.

ORDER NEUROPTERA.

[Wings four, membranous, net-veined, generally large and of nearly equal size: Mouth-parts formed for biting: Metamorphosis complete or incomplete: Abdomen of female with no sting or piercer.]

This is a very heterogeneous Order, and none of its members are of sufficient importance economically to merit special mention here Dr. Hagen, in his synopsis (1861), mentions eight hundred and twelve North American, of which twenty-nine only are from Carolina, while one hundred and four are from Georgia. This, however, cannot be taken as an index to the true number of species in the State

CLASS ARACHNOIDEA.

[Body of two regions (cephalo-thorax and abdomen): thorax with eight legs: abdomen with six spinarets: head without antennæ: No metamorphosis.]

[Jaws used exclusively for biting: abdomen spherical, sac-shaped, not divided into segments, and attached to the cephalo-thorax by a slender pedicel.]
