Truxalis Brasiliensis. Elytris pallide fulvescentibus, vittâ longitudinali mediâ virescenti, nigro irregulariter marginatâ, alis hyalinis dimidio anali roseo. (Expans. Alar. 3 unc. 9 lin.)
Syn. Gryllus brasiliensis, Drury, App. vol. 2.
Habitat: Rio Janeiro, Brazil.
Head long, conical; the mouth seeming placed in the breast. Eyes oblong, situated at the upper part near the extremity of the head; there is also an ocellus placed between them on the under side, which is observable in all those whose heads are shaped like this. Antennæ as long as the head, and shaped like a three-edged sword. Thorax striped with green, brown, and white. Abdomen light brown, and streaked with black at top, but on the sides white. Tegmina light sand-coloured; having in the middle a narrow longitudinal line, indented with green and black. Wings transparent, and prettily dappled; being of a beautiful red colour next the body, which becomes fainter as it approaches the disk of the wings. Hind legs long, and formed for leaping; the others are short. Tibiæ furnished with sharp spines.
Fabricius refers this figure to the Truxalis nasutus Linn. which is found in Africa, and Mr. Smeathman also informed Mr. Drury that the species here figured is found in Africa, in the savannahs, and that its flight is very rapid. I have considered them on the contrary as specifically distinct.
