Show 1900.] FROM SOUTH AND CENTRAL AFRICA. 213 Hab. Salisbury, Mashonaland (67. Marshall). Closely allied to P. humeralis Jac, likewise from Mashonaland, but differing in the black disc of the thorax and in not having a black stripe at the lateral margins of the elytra ; the latter in P. humeralis have the sutural band also extending higher upwards aud not ending abruptly truncate as in the present insect. P. schimperi Lefev. and P. abyssinica Lefev. are likewise closely allied; but the first-named species is described as having the anterior angles of the thorax fulvous only, in having a broad transverse elytral band near the apex, and a subquadrate, not elongate, humeral spot. P. abyssinica has similarly coloured elytra, rufous tarsi, and is smaller. Of the present insect three specimens have been sent by M r . Marshall, of which one has tbe elytral spots widened into a broad band like Lefevre's last-named insect, but the tarsi in all are black; it may, however, possibly be a variety of that insect. GYNANDROPHTHALMA SUBRUGOSA, sp. n. Entirely dark metallic blue ; antennae black ; thorax strongly transverse, impunctate ; elytra very strongly and closely punctured, the interstices irregularly rugose. Length 5|-6 millim. Elongate and parallel, the head nearly impunctate, with a few oblique strigae between the eyes; the latter large, very slightly indented at their lower portion ; epistome with a few punctures, triangularly emarginate at its anterior margin : antennae black, the basal joint metallic blue, the second and third very short, obscure fulvous, the others strongly transverse ; thorax twice as broad as long, slightly narrowed in front, the sides rounded, with a distinct but narrow reflexed margin, the median lobe broadly produced, posterior angles rounded, the disc impunctate, with a short transverse depression at each side; scutellum broad, its apex truncate; elytra feebly lobed below the shoulders, closely and strongly punctured, the interstices transversely rugose, less strongly so towards the apex ; below very sparingly pubescent; the legs rather elongate, the first joint of the tarsi slightly longer than the second. Hab. Cape. (Two specimeus in m y collection.) 67. aspaltina Gerst. seems to be a closely allied species, but is described with finely and remotely punctured elytra, which cannot possibly be applied to the present species, in which these parts are distinctly rugose and strongly punctured. GYNANDROPHTHALMA MARGINICOLLIS, sp. n. Black, finely pubescent below ; thorax transverse, impunctate, the extreme 'lateral margin fulvous; elytra finely punctured, fulvous, a spot on the shoulders, a larger one near the suture at the middle, and a transverse band below the latter, black. Length 5 millim. . Of narrow, elongate and parallel shape; the head black, very PROC. ZOOL. Soc-1900, No. XV. 15 |
