Tribe VI.—Physopoda, or Thrips.
This tribe of insects, to which the name Thysanoptera is sometimes applied, contains many curious forms.
There are two principal groups of these insects—namely, the Tuberlifera and the Terebrantia. They are generally known to gardeners by the name of "Thrips." Some of them occasionally prove injurious to cultivated plants. This is especially the case with the Corn Thrips (Thrips cerealium), which generally attacks the ears of corn, and, when numerous, is very mischievous.
Tribe VII.—Mallophaga or Bird Lice.
These insects, which are known as "Bird Lice," were formerly placed among the true lice, but they differ in the possession of biting mouths, and in the diet to which such a structure adapts them.
A great number of these curious little insects have been recorded, and they inhabit all parts of the world. They live among the feathers of birds and the hairs of mammalia.
