Antennae 13-jointed, subclavate, submoniliform, as long as the body, the third joint the longest, about 1| times as long as the fourth, subclavate, the following joints very slightly increasing in width but very gradually decreasing in length, the three or four terminal joints being almost moniliform and very little longer than thick, the last ovate, a little longer and stouter than the penultimate; the seven terminal joints are all longitudinally striated. Thorax about twice as long as wide and perfectly smooth; the parapsidal furrows start rather close together from the anterior margin of the mesonotum, gradually converge and form a narrow wedge-shaped elevation or carina on its surface; scutellum elevated, rugose, sparsely pubescent, the cup large, oval, its entire disk excavated and with a longitudinal grooved line at bottom, the margins piceous ; metathorax roughened, with the pleura pubescent. Abdomen shorter and much narrower than the thorax, subcompressed, viewed from the side squarely truncate at apex, the apical segments being retracted. Mount Gay Estate. Described from one female specimen. DIGLYPHOSEMA, Forster. D I G L Y P H O S E M A FLAVIPES, Ashm. Journ. Linn. Soc, Zool. xxv. p. 61. Mount Gay Estate. One female specimen. DICERATASPIS, Ashm., gen. nov. Eesembles Hexaplasta, Forster, but is at once separated from it and allied genera by having no pubescent or striated girdle at base of abdomen, and by having the rugose scutellum bidentate behind; i. e. each hind angle is produced into a prominent tooth or prong. The cup is small, ovate, carinated anteriorly, with a fovea on the disk; the antennae are 13-jointed and terminate in an abrupt 6- jointed club ; the marginal cell being open along the fore margin ; while the metanotum is smooth with a median carina. Male unknown. DICERATASPIS GRENADENSIS, sp. n. 2 • Length 1-1 m m . Polished black ; two basal joints of antennae and the legs, including coxae, yellow, the rest of antennae brownish piceous. Wings hyaline, the venation yellowish, the marginal cell open along the fore margin,the second abscissa of radius almost twice as long as the first. The first joint of the funicle is about twice as long as thick, the others a little shorter, subequal, the last being hardly longer than thick; club-joints, except the last, submoniliform, about 1| times as long as thick, the last ovate ; all club-joints faintly striated. Mount Gay Estate. Described from one female specimen. I have also examples of another undescribed species belonging to this genus, collected by Mr. Herbert H . Smith in Brazil. |
