Cup of scutellum narrowed ovate, produced into a carina anteriorly, its disk with a single small fovea or puncture. Wings hyaline, ciliate, the veins yellowish, the marginal cell closed, a little more than 1| times longer than wide, the second branch of radius slightly the longest. Abdomen a little longer than the thorax, with a distinct but narrow girdle of greyish wool at base. Mount Gay Estate. Described from one female specimen. (9) EUCOELA NIGRICEPS, sp. n. d . Length 1*6 m m . Coloured as in preceding species (E. atriceps), but much larger; the antennae 15-jointed, long, filiform, nearly twice the length of body, dusky only toward tips ; the joints of flagellum all long, cylindrical, but very imperceptibly shortening, the last being the shortest and only about two-thirds the length of the first, the first scarcely longer than second; the pedicel rounded, not longer than thick ; the scape subglobose, very little longer than thick. Cup of scutellum large, oval, with a transverse fovea posteriorly, the smooth anterior part with about four small punctures. Wings hyaline, ciliate, the veins yellowish, the marginal cell closed, about twice as long as wide, the second abscissa of radius being If times as long as the first. Mount Gay Estate. Described from one male specimen. Although closely resembling E. atriceps in colour, it cannot possibly be the opposite sex of that species, since it is larger, has a different shaped scutellar cup, and a much longer marginal cell. (10) EUCOELA FERRUGINEA, sp. n. d. Length 1*6 m m . Uniformly reddish brown or ferruginous, the flagellum dusky, while the legs are brownish yellow. Except in the colour of the head it resembles E. nigriceps, but the antennae are a little shorter, with the joints of the flagellum of an equal length, the first being slightly curved or bent, when viewed from the side, while tbe cup of the scutellum is broadly oval, its fovea posteriorly transversely oval and very shallow. Wings as in previous species. Mount Gay Estate. Described from one male specimen. (11) EUCOELA INCONSTANS, sp. n. 2. Length 1*3 m m . Polished black; antennae, except scape and last two or three joints, and legs brownish yellow. Antennae 13-jointed, subclavate, submoniliform, the first joint of flagellum obconic, twice as long as the second, which is only a little longer than thick, joint 3 a little longer than tbe second, joint 4 longer than third and thicker, the joints beyond submoniliform, a |
