In some other orders of insects the cibarial apparatus has but little bearing upon the insect’s mode of life, for in many it is not used either for nutrition or in their economy, or so slightly so as to admit of its being considered of very inferior importance, although systematists—to enhance the value of their own labours, by the frequent difficulty, from excessive minuteness, of its examination—have usually made it a prominent feature in their arrangements. That science has not widely strayed away from the true succession and natural affinities by the main selection of the trophi for the arrangement of the bees, seems partially confirmed by the gradations of form or habit that this method of treatment in general exhibits. A higher method doubtless exists, which would give form, number, and proportion very inferior rank in ordering the arrangement, but at present the clue to it has not been discovered. These questions are indeed beyond the scope of a work of this character, which is merely a ladder to the fruits of learning, and the bearing of them is only hinted at to indicate that there is much exercise for the intelligence in the study of even this small family. The mind that would stop in the study of nature at the knowledge of genera and species, can be very speedily satisfied, and one bright spring day’s successful collecting will furnish the materials for much patient and industrious occupation. In nature we find all things apparently blended in the grandest confusion; but they all have mutual and reciprocal bearings which give a definite purpose to the seeming disorder, and which make each separate unit the centre of all. But we, from our inability to grasp in its fulness the order of this disorder, are obliged to seize fragments and, separating them into what we conceive to be their coherent elements, use them as exponents of the entirety. They could not so exist in nature, but would speedily die out, and it is only by the way in which we find them intermingled, that they can be maintained. Thus, as all conduce to the conservation of each, each conduces to the conservation of all.
