Six specimens of this peculiar insect were taken at Kingstown and various other localities on the island, CIONODEBUS, gen. nov. Long and narrow, with the wing-covers carried flat as and Catonia. Vertex short and nearly square, a little wider than long, with the apex bluntly angular, the margins recurved all around, and the depressed middle carinated, the posterior margin widely sinuated; eyes large, prominent, placed obliquely; front wide, prominently curved above, separated from the vertex by an impressed line ; middle carinated, sides a little expanded in the curve next the epistoma, the epistoma nan*owing to the apex; cheeks wide beneath the eyes, the curve carried above the eyes short. Pronotum with the anterior lobe excavated, protracted into the base of the head like a semicircular valve, with a small tubercle at base, the sides carried down in narrow belts. Mesonotum convex, a little longer than wide, with the tubular middle narrowly oval, margined by carinate lines, and with a carina on the middle; the scutellum triangular depressed in the middle, acuminate. Wing-covers long, bent inwards at tip, opaque, the clavus long, acutely narrowing towards the tip, with the fold near the inner border narrow and nearly parallel with the border; costal area long, widening towards the base of the first forked vein, and narrowed from thence by the curve of that vein; discoidal members of the anteapical series of areoles very long, those near the costal border strongly curved, the apical series shorter and mostly curved. Ocellus placed, as in the preceding genus, at the anterior angle of the eye and beneath it. CIONODEBUS LINEATUS, sp. nov. Chiefly brown above, yellowish testaceous beneath. Head pale, a little clouded across the middle of the front and upon the epistoma; the lateral carinate edges, the front border and carina of the vertex brown. Pronotum marked with brown at intervals. Mesonotum brown, with two middle stripes, the sides, and the borders of the scutellum pale yellowish. Legs mostly pale yellowish, with the tip of tibise and outer surface of tarsi a little dusky. Wing-covers darker brown on the basal two-thirds, including the clavus, but with the veins mostly yellowish; the costal area, including the nodus and the space at fork of radial vein, besides the apex of the clavus and the transverse veins of the membrane, also yellowish. Tergum dark brown. Length to tip of wing-covers 5| mm.; width across middle of mesonotum 1| mm. Two fairly complete, and one mutilated, specimens were secured on the island. |
