Show 1895.] HYMENOPTERA OF THE ISLAND OF GRENADA. 763 first and fourth joints equal, the second and third shorter, about two-thirds the length of the first; club-joints nearly equal, about twice as long as thick, the last ovate and slightly longer than the others. Scutellum rugose, piceous, the cup ovate, with a rounded fovea posteriorly, and from 4 to 6 punctures on the smooth anterior part. Wings hyaline, ciliate, the veins yellowish, tbe marginal cell closed, about twice as long as wide, the second abscissa of radius 1§ times as long as the first. Abdomen a little longer than the thorax, piceous at base, the hair-fringe not dense. Mount Gay Estate (leeward side). Described from one female specimen. (6) HEPTAMEROCERA ALIENA, sp. n. 2 • Length 1*2-1*3 m m . Polished black ; antennae, except the club, rufous ; legs brownish yellow. Antennae 13-jointed, not longer than the thorax; funicle 4- jointed, the first joint about twice as long as the second, the third and fourth only a little longer than thick ; club-joints, except the last, oblong, about 1| times as long as thick, the last ovate, a little longer than the penultimate; all club-joints strongly fluted. Scutellum closely punctate, the cup ovate, with a large deep fovea posteriorly and from 4-6 punctures anteriorly, margins pale. Wings hyaline, ciliate, the veins pale, the marginal cell, except at base, one-third open along the fore margin and about twice as long as wide ; the first abscissa of radius is slightly bent inwardly and about two-thirds the length of the second. Abdomen a little longer than the thorax, with a whitish pubescent girdle at base. Mount Gay Estate (leeward side) and Balthazar (windward side). Described from four female specimens. (7) HEPTAMEROCERA FLAVICORNIS, sp. n. 2 . Length 1*2-1*4 m m . Polished black; antennae, except basal joint and one or two apical joints which are more or less dusky, and legs yellow. Antennae 13-jointed, a little shorter than the body ; funicle 4- jointed, the first and fourth joints equal, about 2\ times as long as thick at apex, the second and third also equal, but only 1| times as long as thick ; club-joints, except the last which is ovate and the largest joint, oblong, about 1\ times as long as thick, the first joint being the slenderest. Cup of scutellum rather large, oval, with a small rounded but not deep fovea a little behind the middle, the disk flat, impunctate, anteriorly sloping but convex (one specimen has the cup of scutellum highly convexly elevated posteriorly, probably from an accident or defect in pupation, since otherwise it agrees with the typical form). Wings hyaline, ciliate, the venation as in previous species. Abdomen with a sparse griseous pubescence at base. Balthazar (windward side). Described from four female specimens. |
