_Pochazia australis_ measures about ¾ of an inch across the short broad fore wings, which are margined and irregularly barred with chocolate brown; the head is short and rounded in front. Melichar, in his “Monographie der Ricaniiden, Wien,” 1898, places _P. australis_ in the Genus _Scolypopa_. The larva is a green wedge-shaped little creature clothed at the tip of the abdomen with a bunch of white filaments. It is a very common insect with a wide range. Sometimes it is a pest on passion vines; the eggs are laid in the slender tendrils, and the larvae suck up the sap of the stalks. Another species is common among the foliage of the silky oak (_Grevillia robusta_) in Southern Queensland. _Achilus flammeus_ has the body and wings of a bright red colour, with the small head showing prominently in front: the broadly rounded opaque elytra and wings cover the short body. It measures about an inch across the outspread wings. Nothing is known about its habits or life history, but in the summer evenings it sometimes comes flying towards the light, and can be found on the windows. The Genus _Poeciloptera_ contains a number of small, short broad-winged forms. Donovan figures _Poeciloptera modesta_, which has pink fore wings, each marked with two small red spots, and the hind wings have a pale bluish tint. _Prolepta dilatata_ is a typical, dull reddish-brown fulgorid, measuring nearly an inch from the tip of the long slender head to the extremities of the folded tegmina which are broadest across the tips: and the slender prolonged forehead is over two lines in length. This insect was described from W. Australia, but it has a wide range and can be collected about Sydney. _P. obscurata_ is about the same size, more rugose in structure, and with markings of dark brown; the markings on the somewhat opaque wings are more distinct, striated and irregular than in _P. dilatata_: it can also be easily recognised by the shorter and thicker process on the forehead. It has a wide range over Australia. The Genus _Eurybrachys_ contains a number of short, dark brown insects with broad rounded heads; they run about on the trunks of trees, jumping at the least alarm. _Eurybrachys leucostigma_ is a very stout, broad, dull brown insect, about ¾ of an inch across the outspread wings. Some 16 species are described from all parts of Australia. The members of the Genera _Ledra_ and _Stenocotis_ are broad elongate insects with the front of the head spade-shaped, and the convex body tapers to a sharp point. Their larvae are almost as flat as a bit of paper. _Stenocotis australis_ is about ¾ of an inch in length, and of a dull brown tint. Family 5. Leaf-Hoppers. JASSIDAE.
