Show 264 MR. M. JACOBY ON THE [Feb. 2, sutural, basal, and the lateral margin posteriorly black, below the base four black spots of irregular shape are placed in an oblique quadrate position, of these, one is situated on the shoulder, the other directly below it, the other two between the lateral spots and the suture, also below each other, occupying the third and fourth and the fifth, sixth, and seventh interstices respectively, the A-shaped marked is placed below the middle near the lateral margin and is sometimes divided into two irregular spots; pygidium fulvous, finely pubescent; underside and legs of the same colour ; the sides of the breast and a spot on the upper portion of the femora blackish. Hah. Natal, Estcourt (67. Marshall). In the markings of the thorax this species resembles 67. denti-culatus, Suffr., of which it may possibly be an extreme variety ; I have, however, two specimens before m e which almost entirely agree with each other, and in these the elytral markings are quite different from the above-named species, especially in the very narrow black sutural aud lateral margin (the last of which commences at the middle only). Suffrian also speaks of finely wrinkled and punctured elytral interstices, of which there is no trace in the present insect. CGENOBIUS FLAVITARSIS, n. sp. Black, shining, the basal joints of the antennas, the apex of the tibias, and the tarsi flavous; thorax strongly punctured; elytra very strongly punctate-striate, the interstices longitudinally costate at the sides. Length f- line. Head black; the entire vertex and the sides occupied by the eyes, which meet at the top ; antennas extending a little beyond the base of the thorax, black, the basal five joints flavous, third and fourth joint very small, terminal joints distinctly widened; thorax about one-half broader than long, the sides nearly straight and much narrowed anteriorly, the surface with a deep transverse oblique groove at each side, strongly and rather closely punctured, the punctures somewhat oblong in shape, the basal margin with a row of deep and closely placed punctures ; scutellum narrowly elongate; elytra with very deep and close rows of punctures, the shoulders very prominent, the basal margin in shape of a ridge, the interstices longitudinally costate, more strongly so at the sides than at the disc; the underside, pygidium, and the legs black, the extreme apex of the tibias and the tarsi flavous. Hah. Mashonaland (67. Marshall). A single specimen in the British Museum collection. Allied to 67. nlgrltellus, Suffr., but at once distinguished by the flavous tarsi and the sculpturing of the thorax & c C. suffrlanl, Jac, has the head strigose at the vertex, the antennas scarcely widened, the thorax without lateral depressions, and the tarsi black. CHLAMYS NATALENSIS, n. sp. Obscure fulvous or piceous ; the antennas and the tibias fulvous • |
