Other specimens were found at various points on the island, which are not recorded in any list accessible to me. The generic name given above is derived from that of the great tract of land belonging to the Caton family in Maryland, where Plata (Catonia) nava, Say, occurs, and where another species, Cixius (Catonia) cinctifrons, Fitch, abounds in autumn upon the white hickory and oak trees. CUBANA, gen. nov. Abdomen more prismatic above and less flat than in Catonia, with the hemelytra opaque, and the membrane not bent inwards as in that genus. Head a little longer than the eyes, with the lateral keels highly arched above the surface of the vertex and front; the vertex deeply sunken, almost regularly quadrangular, with the middle keel more distinct in one species than in the other ; front long and moderately wide, the side strongly carinate and curving, becoming widest at the clypeus, and the curve continued tapering to the tip, the middle carina exceptionally high, as much elevated as the lateral margins, complete to tip of clypeus. Pronotum unusually short, expanding into saddle-flaps each side inferiorly. Mesonotum with a tabular disk, which is much longer than wide, tricarinate, the outer carina? spreading apart posteriorly, and behind this point the scutellum extends back in a triangle. Wing-covers growing very gradually wider towards the tip, bluntly rounded at tip; four long discoidal areoles running out to the oblique cross-veins, which form the base of the apical areoles; the costal area crossed by three oblique veins before reaching the nodal mark, this latter followed by about four curved veins before the apex is reached ; areoles of apical series long, the fork connected with the middle vein longer than the others ; basal areole small and narrow ; wings with three forked veins and two transverse veins towards the tip. Posterior tibise destitute of spines before the tip. The generic name here given is derived from Cuba, on which island these insects were first taken. CUBANA TOBTEIX, sp. nov. Pale dull brown, moderately robust, with all the carinate lines and borders and tip of scutellum pale testaceous. Grooves of face blackish. Underside of body mostly pale testaceous. Legs testaceous, with the spurs of tibia? and tips of tarsi piceous. Wing-covers shaded with pale brown, the veins mostly ivory-vellow ; the cross-veins of costal area, an oval spot beyond the tip of the costa, almost encircled by a slender arc before and behind, the slender apical margin, a bent line crossing the membrane diagonally near its middle, a paler bent line across the middle of the corium, and a short stripe at the apex connected with the |
