These grasshoppers are found not only among the grass but on low shrubs, or in tree tops, feeding upon the foliage; while others, many of them wingless, live underground after the manner of crickets. Among those that frequent trees are some that, like the phasmids, have the legs and wing-covers so wonderfully veined and spotted that they are an exact imitation of the leaves of their food plant. They are easily distinguished from the previous group by their long, slender, thread-like antennae composed of a number of fine joints; in most cases the body is softer; and in the female furnished with a sabre-like ovipositor with which she generally deposits her eggs in rows along the side of a leaf or twig, though others place them on the ground. The basal portion of the thigh of the hind leg is generally thickest, and most of the species have four jointed tarsi, with the ear process not upon the base of the abdomen, but on the knees of the fore-legs. Some are said to be carnivorous, and I have twice seen a large green species which comes to the flowers of the stunted angophora devouring honey bees, but probably more for the honey they contain than the blood of the bee. Brunner von Wattenwyl has written a great deal about these insects and described a number of Australian species. Tepper is one of the few Australian entomologists who has taken up this group, describing some in the Transactions of the Royal Society of S. Australia: in the Locustidae of the world Sharp groups them into fifteen tribes. Most of these Orthoptera are solitary or found in pairs; some too have a very musical note. The Mountain Grasshopper, _Acridopeza reticulata_, is such a curious looking creature that it has been figured and noted by many naturalists. Both sexes are of a uniform dull brown colour, but very different in structure; the male measures 2 inches; has long pointed elytra, and well developed wings; the head is small; the antennae slender and thread-like; the eyes stand out on the side of the head, and the thorax is saddle shaped. The female is furnished with a very short, rounded body richly mottled with blue, white, and red, covered with a pair of rounded, short, shell-like elytra, but the wings are wanting. When disturbed she stands on tiptoes, arches her body, raises her elytra exposing all the bright tints of her body, which probably act as a warning to her enemies.
