Show 1895.] HYMENOPTERA OF THE ISLAND OF GRENADA. 751 posteriorly which occupies about half the surface. Wings hyaline, entire at apex, the veins light brown, the marginal vein open along the fore margin, the second abscissa of radius a little longer than the first. Abdomen with a sparse pubescent girdle at base. Balthazar (windward side). Described from one female specimen. HEPTAMERIS, Forster. H E P T A M E R I S FLAVIPES, sp. n. 2 • Length 1 m m . Polished black; antennse, except the 7-jointed club, and legs yellow. Antennae 13-jointed, not quite so long as the body, the scape only a little longer than the pedicel; funicle 4-jointed, slender, the first joint the longest, not quite twice so long as the second, joints 2-4 subequal, longer than thick; club abrupt, 7-jointed, the joints subequal, about 2 | times as long as thick, fluted, the last joint slightly the longest. Mesonotum as long as wide at base; scutellum indistinctly striate, the cup oval, smooth on the disk, with a small fovea posteriorly and some punctures anteriorly. Wings hyaline; the veins yellowish, the anterior wings slightly emarginate at apex, the marginal cell closed along the fore margin for more than half its length, the second abscissa of radius 1| times as long as the first. Abdomen black, a little longer than the thorax, with a slender pubescent girdle at base. Balthazar. Described from one female specimen. PARAMIOMCEA, Ashm., g. n. 2 . Antennae 12-jointed, with an abrupt 7-jointed club; the scape obconical, only a little longer than the pedicel, which is rounded; funicle 3-jointed, the first joint not quite so long as the second and third united, which are moniliform; club 7-jointed, the joints about equal in size, strongly fluted. Scutellum rugose, the cup rather large, oval, the carina separating it from the mesonotum very short, the disk with a fovea posteriorly and a few punctures anteriorly. Wings with a closed marginal cell, the first abscissa of radius shorter than the second. Otherwise as in Eucoela. This genus is distinguished from all other genera in the Eucoelince, except Miomcea and Idiomorpha, Forster, by having only 12-jointed antennae, and from these two genera by its scutellar and antennal characteristics. In Miomcea the cup of the scutellum is large, rounded, with the whole disk impressed, while the antennae are filiform, with the first flagellar joint the longest and curved. In Idiomorpha the marginal cell is closed, while the antennae are also different. PARAMIOMCSA HEPTATOMA, sp. n. 2. Length 1*25 m m . Polished black; basal five joints of antennae and legs brownish yellow; club-joints black, strongly fluted ; clypeus and mandibles rufous. Wings hyaline, ciliate, the veins light brown, the marginal cell closed, not quite twice so long 48* |
