Antennae in $ 12-jointed, subclavate, the flagellum gradually incrassated towards tip and without a distinctly defined club ; in o* 14-jointed, as in Diapria, pediceMate-verticellate; scutellum conic, ending in a spine and foveated at base; metathorax armed with an acute curved thorn or spine; wings as in Diapria ; body of abdomen short oval, truncate at apex, the petiole short, stout. This genus is separated at once from Diapria and Tropidopria, to which it is most closely allied, by the conic, spined scutellum, by the acute spine on the metathorax, the short oval abdomen, and by the antennal characteristics of the female. ACANTHOPRIA CRASSICORNIS, sp. n. 2 . Length 1*4 m m . Polished black ; antennae, except the last 5 joints which are dusky or black, and legs red; metathorax and petiole of abdomen brown, pubescent; wings hyaline, ciliated. The head is globose; antennae nearly as long as the body, subclavate or gradually incrassated toward tips ; scape long, half the length of flagellum, stout, extending far above the ocelli; pedicel about half as long as the first flagellar joint; flagellum stout, the first joint the longest, the following joints to the seventh gradually shortening, but increasing in width, the joints from 8th tapering toward apex. Mesonotum with two faint grooved lines posteriorly; scutellum conic, ending in a spine or thorn, with a deep fovea at base; metanotum armed with an acute prominent thorn or spine at base above, the metathorax and abdominal petiole rugulose ; body of abdomen oval, much shorter than the thorax, its base overlapping the apex of the petiole; petiole a little longer than thick. d . Length 1*4 m m . Agrees structurally very closely with the female, except that the delicate grooved lines on the mesonotum are wanting ; sometimes the thorax above anteriorly and at the sides is piceous or rufo-piceous; the antennae and legs are reddish yellow, the former being about twice as long as the body, pedicellate-verticellate, exactly as in Diapria. Balthazar and Mount Gay Estate. Described from one female and four male specimens. DIAPRIA, Latreille. Table of Species. Females. Body uniformly rufo-piceous Body mostly black. Thorax entirely black. Antennas gradually incrassated, red, the first flagellar joint longer than the pedicel Thorax anteriorly and the abdomen beneath piceous or dark rufous, not entirely black. Club of antennas 4-jointed, gradually incrassated, the last joint not twice as long as the penultimate, the last two joints black 2. D. smithi. D. grenadensis. |
