. Annals of the South African Museum. Annale van die Suid-Afrikaanse Museum. Natural history. Descriptions of Neiv or Little-known Orthoptera. 445 AROEGAS, n. gen. Vertex somewhat convex, the fastigium prolonged triangularly, attenuate rounded at tip and overhanging the frontal; antennae slender; prouotum oblong, twice as long as broad, not grooved, saddle- shaped, wider across the centre than at apex or base, broadly rounded behind, and covering only the base of the first abdominal segment; no wings ; abdomen as long as the head and prouotum ; prosternum simple; coxae with a short sharp spine ; anterior and intermediate tibiae moderately long, the former with an ovate tympanu-m ; fore tibiae with three spines underneath on each side, posterior with a double series above, simple underneath, femora simple ; supra-anal. FIG. 5.—Aroegas nigroornatus, $. lamina $ deeply scooped with the angles sharply dentiform ; cerci short, thick, tapering into a sharp point: sub-genital lamina very long, deeply and broadly grooved in the centre, narrowed from the median part to the apex ; this narrowed part is very strongly recurved, bluntly trifid at apex, and fits, when at rest, in the scooped-out space of the supra-anal lamina. The general facies is that of Arytropteris of the pulchripes type, but it is easily distinguished from this genus by the presence of well- developed tympanum, and the shorter fore and intermediate legs. The shape of the sub-genital lamina is very singular. I find no traces of styles in the only example in the Collection. AROEGAS NIGROORNATUS, n. sp. $ . Straw-colour, with the antennae fusco-auuulate, a conspicuous broad arcuate black baud on the top of the declivity of the anterior.
