In one point of view these two divisions are of considerable value, as they afford an obvious and broad basis upon which to build the minor divisions of a system; but like many other distinctions in natural history, it requires no little refinement of erudition to render the principle in all cases practically applicable. An intelligent reader, for example, who has not paid much attention to the study of insects, upon being told that all insects either masticate solids or suck fluids, may wish to verify the distinction upon the first he meets with: and if he chance to light upon a beetle or a gnat, he will find that the former has jaws and the latter a sucker; but if a bee should come in his way, he would be somewhat embarrassed, for, upon perceiving its large jaws, he would be disposed to arrange it among eating insects, did he not advert to the well-known fact of its lapping honey with its tongue--an organ no less conspicuous than its jaws.

Aristotle was shrewd enough to perceive this difficulty, when he says of such insects (Hymenoptera) that they have teeth, not for feeding but for fulfilling other instincts, such as building cells of wax, and similar materials.
