Show 1891.] OP ST. VINCENT, WEST INDIES. 159 OMMATIDES, gen. nov. Coleopterine, closely resembling a short thick Geoeoris. Eyes very large, oval, projecting diagonally against the anterior corner of the pronotum; front of the head short, bluntly tumid, with the face vertical, protracted downward, and having long lobate cheeks which converge over the base of the rostrum ; antennae filiform beyond the second joint, the basal joint shorter and a little thicker than the second ; rostrum thick at base, short, tapering, quite slender towards the tip, reaching almost to the middle coxae. Pronotum very short, almost annular, with the sides rounded off anteriorly to admit the form of the eyes, the posterior margin almost straight. The two forward pairs of legs placed near together ; the anterior tibiae greatly thickened at tip and armed with long spines. Scutellum very short, transverse, triangular. Hemelytra high convex, extending amply over the abdomen and much longer than it; the costal border moderately curved, with the middle areole moderately wide, and the thick cubital vein running back parallel with the next inner vein all the way to tip of membrane, and with the two exterior transverse veins as in Schizoptera. OMMATIDES INSIGNIS, sp. nov. Ovate, blunt and wide in front; orange, with the pronotum, scutellum, and a broad band behind the scutellum, covering the membrane, blue-black. The head reddish brown above, yellow below the origin of the tylus, obsoletely scabrous, very minutely pubescent. Legs polished, stout, bright yellow, remotely hairy. Pronotum moderately arched, opaque, a little scabrous. Hemelytra thick, opaque, velvety; the membrane but little thinner than the corium, with the inner margin straight, not overlapping at tip, the apex a little tapering and rounded at tip. Length to tip of membrane 1 millim.; width of pronotum H millim. A single specimen of this peculiar little insect was taken, but no record is given concerning the place where it was found. ONCERODES, gen. nov. Coleopterine, and resembling an Issus in form ; the hemelytra particularly wide and subglobose, blunt at the anterior end. Head nearly vertical, short and broad, moderately convex before the line of the eyes, transversely impressed between them; the cheeks separated by deep vertical lines, the tylus nearly linear; rostrum very short and thick, tapering at tip, fitting very compactly into the sternum, reaching to tip of anterior coxae; antennae with the two basal joints thick, the second joint a little shorter and not so thick as the first, the remaining joints thread-like, finely pubescent. Pronotum transverse, nearly crescent-shaped, moderately arched, having the anterior angles rounded off to fit the curve of the eyes. Scutellum acutely triangular, much longer than wide. Hemelytra but little longer than wide, suborbicular, narrower at base, corresponding to the width of the pronotum; the veins coarse and |
