Rh TRUXALIS CONICUS. XVII. Fig. 2. Gryllus Locusta Conicus. Stoll's Saut. de Pass. Pl. 23. b. Fig. 88. singular genus is at once known by the narrow conical head, which is longer than the thorax; and by the antennæ, which are ensiform and prismatic, as long as the head and thorax taken together, multi-articulate, and inserted between the eyes at the extremity of the head; the body long and narrow; legs slender and lengthened. The species, which are not numerous, and by no means accurately distinguished, are peculiar to warm climates, and we know scarcely any thing of their manners. The figure referred to above, may possibly represent a variety of T. Nasutus, although Stoll, from whom we have copied it, regards it as distinct. The thorax and tegmina are brownish yellow, the latter with a crenated white ray along each; abdomen marked with yellow and black spots; legs brown. Fig. 3d, of the same Plate, represents a species named T. brasiliensis by Drury. It is closely allied to T. nasutus as well as T. conicus. The tegmina are pale fulvous, with a green stripe along the centre of each, irregularly indented on the hinder edge with black; wings transparent, the basal portion tinged with a delicate and beautiful red. Its habitat is Rio Janeiro, Brazil, &c.
