These include some beautiful insects. The care with which the many thousand varieties have been classified by zoologists, and the minuteness with which the habits of each variety have been traced, have raised these insects to a conspicuous position in the great Animal Kingdom. Their beauty, as they lie here in vast numbers before the spectator, is dazzling. Every colour and every combination and shade of colour can be traced upon them; and in these varieties of tint there appears to be a wise provision of nature, the blue coloured beetle being the frequenter of the bark of trees, the green beetle revelling among the leaves; and the gay red and light beetles being the _habitées_ of flower cups. Upon the first table of the series (1) are some curious varieties. Here are the remarkable burying-beetle, that deposits its eggs in the rotting flesh of small dead animals, and then, with the assistance of some kindred beetles buries the body, leaving its progeny to enjoy the carrion when they quicken; the sacred scarabaeus of the Egyptians, and the British variety of the same beetle, that bury their eggs in their dung. Upon the next table (2) are the golden tropical beetles, whose wings are used by the natives as ornaments; the celebrated glow worms, the females of which emit a phosphorescent light, in order to attract the attention of the males--thus these lights are love signals; the Brazilian diamond-beetle, a splendid insect, and the harlequin beetle. The third table (3) is covered with varieties of the kangaroo beetles, a brilliant collection of ladybirds, the varieties of earwigs, cockroaches, originally tropical insects only; the praying insects, called so from their habit of erecting their fore legs and assuming a prayerful attitude, when, in fact, they are preparing for an attack upon their prey: and the insects which the uninitiated visitor has already mistaken for pieces of stick, but which are the walking leaf-insects; some with wings like dead leaves, and others wingless. The fourth table (4) is covered with the varieties of the Cricket, including the great Chinese cricket, dragon-flies, scorpion-flies, the terrible tropical white ants, caddis flies, wasps, saw-flies, bees, hornets, and sand wasps. BUTTERFLIES AND MOTHS. Then follow three tables (5-7) of splendid butterflies, with their brilliant tints. The two tables (8, 9) ranged next in order to those upon which the butterflies are distributed, are covered with varieties of the moth. Here are the silkworm moth and its cocoon as kept in Siberia; the ghost moth of our hop grounds; the hawk moth, the death's head moth, and the large Brazilian owl moth. The next table (10) is covered with a great variety of flies and bugs, including the Chinese lantern flies.
