Cyrtacanthacris ruficornis.

  • Gryllus ruficornis, Fabr. Ent. Syst. ii. p. 54, n. 28 (1793).

One of the great migratory locusts of Africa. The description of Fabricius seems to have been taken from an unusually dark specimen.

    strong spines, extending on each side nearly to the level of the front coxæ Aprophantia maculata, sp. n. Long. corp. 38-48 millim. Testaceous yellow (probably green during life); the tips of the spines, a double row of spots more or less complete on both sides of the femora, and a patch over the foramina on the front tibiæ black. Antennæ testaceous, with five long black bands increasing in length, the last terminal. Male with some obsolete brown markings on the face, two running up from above the frontal horn, and one on each side beyond, angulated outwards. The male also has some obsolete depressed brown marks on the front and sides of the thorax above, nearly as in the species of true Cosmoderus. In the female these markings are wanting, and the colour is darker, especially at the sides of the thorax, the front and back of the abdomen, and towards the extremities of the tibiæ, and along their carinæ. The male has three pairs of spines on the femora beneath and two additional spines en the outer carina of the hind femora, and six pairs of spines on the four front tibiæ, and eight or nine rows of spines (not all paired) on the hind tibiæ. The female differs in having five pairs of spines on the hind femora, but the legs are otherwise spined nearly as in the male. Described from a single pair (♂ and ♀) from the Cameroons.
