(Plate LII. fig. 11.) Pentatoma albonotata Westw. in Hope Cat. i. p. 37 (1837). Hab. Gambia. MENIDA HISTRIO. Cimex histrio Fabr. Mant. ii. p. 296. n. 176 (1787). Pentatoma bengalensis Westw. in Hope Cat. i. p. 36 (1837). OCIRRHOE ROEI. (Plate LII. fig. 12.) Rhynchocoris roei Westw. in Hope Cat. i. p. 30 (1837) ; Leth. & Sev. Cat. Gen. Hem. i. p. 181 (1893). The species identified by Dallas (List Hem. i. p. 297. n. 4,1851) is not conspecific. OCIRRHOE ? VIRESCENS. (Plate LIII. fig. 7.) Raphigaster virescens Westw. in Hope Cat. i. p. 31 (1837). The type and only specimen is in a very mutilated condition? wanting the abdomen, but the species apparently belongs to the genus Ocirrhoe. AVICENNA, gen. nov. Head deflected, moderately broad, lobes of equal length, apex rounded, lateral margins moderately sinuate at about centre. Antennae with the second and third joints subequal in length, or second slightly shorter than the third. Pronotum strongly deflected anteriorly from between the area of the lateral angles ; lateral margins moderately concavely sinuate, punctate before anterior margin, posterior margin strongly concave at base of scutellum ; posterior angles subprominent, lateral angles produced in long acute spines. Scutellum broad, distinctly narrowed a little before apex. Rostrum with the second and third joints about subequal in length. Sternal process extending beyond base of head. Spines at apices of sixth abdominal segment and anus strongly developed. This genus agrees with Moma in the concave posterior margin of the pronotum, but differs in not having the posterior pronotal angles acutely produced. It is allied to Vitellus by the shape and production of the sternal process, but differs by tbe less triangular and elongate head, the longer and non-triangular scutellum, &c. AVICENNA INQUINATA.
