Dead stumps and pardy dead, infested plants should be removed and burnt, to deprive the insects of congenial quarters. The true home of the Termites is in the tropics, where they are pests of the first magnitude. In Africa some of the species are mound-builders, erecting turreted structures from ten to fif- teen feet in height, made up of earth and partly digested wood and other fibre. Family psocid^.

They are always small, resembling somewhat a "Termite" in miniature, very active, running backward or for- ward with equal facility, and furnished with very long, slender antennae or feelers. The head Fig. A book-louse, X 25 diameters. is very large, with small, coarsely granulated com- pound eyes. The mouth or- gans are mandibulate, but not at all prominent, and fitted for gnawing rather than biting,—whence the insects have been called Corrodentia or '' gnawers.'' They are white or dirty-yellow in color, and look just enough like true lice to be mistaken for them under some circum- stances.
