Show 1893.] FROM ST. VINCENT, WEST INDIES. 715 orange, and this colour covers the entire cuneus, the outer border and cuneus less coarsely punctate than the clavus. Venter blackish, with the disk basally dull orange. Length to end of venter 2|-3 millim., to tip of membrane 4-4^ millim.; width of pronotum 1^-1^ millim. Three mature specimens, a male and two females, and two larvae-were secured. These were met with on both sides of the island, and the larvae were obtained at the roots of grass on the marsh 500 feet above the level of the sea. This genus belongs to the division Clivinemaria of Reuter, and this species, together with the two other hooded species of Mr. Distant, may eventually be found to belong to the genus Clivinema, Reuter. In this genus there is lack of uniformity in the proportions of the antennse, not only in the two sexes, but also among individuals of the same species. Genus PO:OILOSCYTUS, Fieber. PffiCILOSCYTUS O B S C U R U S , sp. nov. Closely related to P. basalis, Reuter. Dark chestnut-brown, oblong-ovate, spread with close fine golden pubescence; female broader than the male. Head long, acutely triangular, dull, not distinctly punctate, polished when denuded; face convex, surface around the eyes, a slender streak on the middle, and the cheeks each side of tylus more or less yellowish ; the tylus, bucculae, and base, tip, and middle of rostrum dark brown, the rostrum mostly yellowish and reaching behind the posterior coxae; the transverse carina at base of head prominent, piceous, polished. Antennae of medium thickness, as long as from front of eye to tip of cuneus; the joints either dark brown or pale with brown ends, excepting the apical ones which are pale fuscous and nearly setaceous ; the second joint is about as long as the base of pronotum. The pronotum is moderately convex, obsoletely punctate, and covered with the same prostrate golden pubescence as the head, scutellum, and hemelytra; the collum is generally testaceous or wdiite, and back of its middle is a short yellow double spot or band, against each anterior angle there is usually a velvet-black round spot, the posterior margin is a little sinuated and usually pale ; the sternum, posterior border of pleural segments, and coxae are usually pale testaceous. Legs dark brown in full-coloured specimens, but pale yellowish brown in others, paler on the tibise, and having the posterior femora marked near the tip by the usual two darker bands. Scutellum moderately convex, obsoletely wrinkled and punctate, bordered with testaceous near the tip. Corium, clavus, and cuneus finely but distinctly punctate, the embolium and costa with a testaceous spot at base, the fracture and tip of cuneus and vein of membrane dull testaceous; the membrane dark fuliginous.
