Thorax black with a yellow line above; head as wide as the thorax, with a blunted projection in front between the antennae, which are very long and situated in a groove in front of the eyes, and have their basal joint very large. No ocelli visible. Thorax wider than long, somewhat narrower in front than behind. Hemelytra very transparent, longer than the abdomen, lying flat upon one another, the outer margin bent down; the horizontal portion has many irregular nerves; there are two longitudinal nerves at the angle formed by the bent down outer margin, which extend from base almost to the tip, the spaces between these nerves being of a yellowish colour, the general colour greyish, there are several oblique parallel veins on the bent down margin; wings very short; posterior legs very long; femora much thickened, brown, at the base very pale; anal appendages very long and hairy. Somewhat allied to the Acheta arachnoides of Westwood, figured in the Naturalist's Library, Introduction to Entomology, volume 1 plate 6. Habitat King George's Sound, Captain George Grey. Tympanophora pellucida, new species. Illustration 22 Insects 5. Antennae very long, arising from between the eyes, labrum heart-shaped, eyes very large, prominent; ocelli 3, the first the largest, situated between the antennae, the two others being placed on the sides of a slight groove behind them. Prothorax widest behind, in front not so wide as the head; abdomen small, two of the segments on the back with projecting knobs; anal appendages in the male short cylindrical, slightly hooked inwardly, furnished at the end with two teeth, the surface is rough with short bristly hairs. The elytra are much longer than the wing, which again are at least twice the length of the abdomen; the first and second pair of legs are rather stout, the tibiae having two rows of strong spines on the underside; the hind legs are long and slender, the under surface of the tibiae being but slightly denticulated. The head is green, the front inclining to yellow, the crown is reddish brown, eyes green, ocelli yellow, two basal joints of antennae green, the remainder rust coloured; prothorax green, brown behind, with a broadish line of same colour down the middle; body rusty green, each segment with a dusky ring; elytra pale green with few longitudinal nerves, but many cross ones; wings of a very pale green; anterior legs of a pale brown, femora of second and third pair green; the tibiae pale brown, the tarsi and joints darker. Habitat King George's Sound. This genus is not far removed from AEcanthus Serville; when the wings are closed it somewhat resembles a species of the African genus Pneumora; (the figure should be reversed.) Saga denticulata, new species.
