Insects -- Australia
Another remarkable grasshopper is _Alectoria superba_, found in
the dry western country among the grass; it is a long, slender, green
insect, measuring 2½ inches; the elytra and legs are richly mottled
with bright reddish brown; the thorax is produced into a large circular
crest edged with bright red, a large boss below on either side,
and another projecting above the head. The female has a very small
lance-like ovipositor. The Speckled Green Grasshopper, _Ephippitytha
32-guttata_, is about the same length as the last, of a somewhat
lighter green tint, and has the elytra mottled with a double row of
black spots varying from 32 to 44 in number. The head is small, the
thorax short and somewhat saddle-shaped. It is found about Sydney
on flowering shrubs; and there is a darker variety which has a wide
range over the interior, to which Tepper has given the name of _E.
quadrigesima-guttatus_. The Small Green Grasshopper, _Caedicia valida_,
is one of our dainty, slender, green species found in the gardens,
where it sometimes damages the young fruit by gnawing patches off the
skin, or nibbles holes in the foliage; it produces a sharp musical note
uttered three times in succession.
The Large Green Leaf Grasshopper, _Locusta vigentissima_, figured by
McCoy, is also found on low shrubs in the summer; it measures nearly 3
inches, and is of a uniform dull green colour, with the head, legs and
antennae more or less yellow: the head is broad; the thorax stout; the
legs long and spiny; the elytra long, tapering to the tips; the wings
large, semitransparent; the abdomen short, in the female furnished
with a long sabre-like ovipositor. The Lance-headed Grasshopper,
_Pseudorhynchus lessonii_, has a wide range along the eastern coast
among the long grass; it is green, with the tips of the elytra marked
with yellow; the wings are small, and the front of the head produced
into a lance-like point. Among the foliage of the eucalypts in Southern
Australia there is a very handsome large grasshopper with the head
small, the thorax very square, and the elytra very leaf-like in form;
it has a curious bloom upon it like that upon many of the gum leaves,
and is a very fine case of mimicry.
The Genus _Anostosoma_ comprises a number of reddish brown wingless
locusts more like crickets in many ways, for they live chiefly in
holes in the ground, have long thread-like antennae, and stout spiny
legs. _Anostosoma australasiae_ is a very formidable looking insect
with immense head and jaws, originally described from Moreton Bay;
it is sometimes found about Sydney, measuring 3 inches in length; it
has antennae over 4 inches long. The smaller species, _Anostosoma
erinaceus_, is of a similar colour and form, but not more than 1½
inches in length; it is not uncommon in gardens.
