the whole of southern Europe, Barbary, and Egypt. The paintings and amulets of the ancient Egyptians very often represent it, and sometimes give it a gigantic size. It is, doubtless, then, this species which was an object of veneration with the Egyptians.

There exists another species, which is always represented as of a magnificent golden green, and to which Herodotus also attributes this colour. As it was not to be found in Egypt, it was thought for a long while that the Egyptians had painted the black species of a more splendid colour in order to pay it homage. But in 1819 M. Caillaud actually found at Meroe, on the banks of the White Nile, the Ateiichiis JEgyptiorum^ which resembles the Atcnchus sacer much in colour, but has a golden tint. Since then it has also been brought from Sennaar. The two species were both probably sacred. Hor- Apollon, the learned commentator on Egyptian hieroglyphics, thinks

that this people, in adopting the scarabaeus as a religious symbol, wished to represent at once, a unique birth — a father — the world — a man. The unique birth means that the scarabaeus has no mother. A male wishing to procreate, said the Egyptians, takes the dung of an ox, works it up into a ball, and gives it the shape of the world, rolls it with its hind legs from east to west, and places it in the ground, where it remains twenty-eight days; the twenty-ninth day it throws its ball, now open, into the water, and there comes forth a male scarabaeus. This explanation shows also why the scarabaeus was employed to represent at the same time a father^ a majt, and the world. There were, however, according to the same author, three sorts of Scarabai: one was in the shape of a cat, and threw out brightly shining rays (probably the Golden Scarabaeus, Ateuchus ^■Egyptioruin); the two others had horns; their description seems to refer to a Copris and a Geotrupes.

As other remarkable species of Scarabcei we represent the Scarabceus enema (Fig. 441), with strong horns, the Megaceras chorincBtis (Fig. 443), the Megalosoma anubis (Figs. 444 and 445), and the Dynastes Hercules (Fig. 446).

The last family of the Scarabceidce contains the Lucanidce, or Stag Beetles. These Coleoptera are of great size, and their head is armed with enormous robust mandibles, which give them a ferocious air, which their inoffensive habits do not in any way justify. They live in half-rotten trees, the destruction of which they accelerate. Their mandibles, of such prodigious size only in the male, are of more inconvenience to them than they are of use, as they impede their flight. Their strength enables them to raise considerable weights, but they make no other use of them than to show their strength, which is enormous.- They do not attack other insects, and live only on vegetable juices. The common Stag Beetle (Figs. 447* and 448) attains to a length of two inches, or more, including its mandibles, and is of a dark brown chestnut colour. They are met with during the months of May, June, and July, in large forests, climbing along trees and hooking themselves on to the trunks by their mandibles. Charles De Geer says that the Stag Beetle imbibes the honeyed liquid which is found on oak trees, a tree it particularly seeks after, which has cau.sed it to

The Syndesus coriudus (Fig. 452) of Tasmania, and the ChiasO' gnathus Gfattfit, from the coast of Chili (Fig. 453), of a beautiful golden green shot with copper, belong to genera akin to Lucanus.

We arrive now at the tribe of Silphales, which are still more useful to man than the Dung Beetles {Scarab(eides\ since many of them disencumber the soil of the carcases of animals in a state of

putrefaction. The most remarkable insects of this tribe are the Histers (Fig. 454), the Stlphce, properly so called, and the Necrophori.

The Histers are small insects, to be recognised by their body being almost round, smooth, and shining, with the elytra marked with strias,

and their mandibles pretty well developed. They attain to a length of about a fifth of an inch. The Silphce, thus named on account of their broad and rounded form, are of a large size (about half to three-quarters of an inch), of a dark colour, and exhale a sickly odour.

\ Necrophori, or Grave-diggers, are honest undertakers, who carefully bury carcases left on the soil. As soon as they smell a field-mouse, a mole, or a fish in a state of decomposition, they come by troops to

Necrophori sink it still lower — as far as from seven to ten inches below the surface. They then mount it, cast the earth down into the grave so as to fill it, and the females lay their eggs in the tomb, where the larvae will find an abundance of food. When the ground is too hard to be dug, the Necrophori push the carcase further, till they find

They scooped out the soil underneath the stick, and lout through the string, and the mole was buried in spite of the obstacles. Fig. 460 represents a troop of Necrophori burying a small rat.'

They are, for the most part, of small size, and are distinguished by their elytra, which are short, and resemble a waistcoat or a jacket; but their wings are fully developed. The large species have strong mandibles. When irritated, the Staphylini disgorge an acrid black liquid; and by the abdomen they emit a volatile fluid having a musky odour.

We see frequently on roads the Staphylinus olens (Figs. 463 and .464), which, when it finds itself attacked, raises its abdomen, and thrusts out two little whitish bladders, - which pour out a volatile liquid. Its larva Hves under stones, and its habits are the same as those of the adult insect. It is very carnivorous, and very active, and often attacks those of its own kind. The Staphylinus hirius
