Also at St. George's and on the Mount Gay estate, in September, from herbage on low grounds. CORYTHAICA, Stal. CORYTHAICA CARINATA, sp. nOV. Oblong, narrow, pale fuscous, sinuated on the sides of pronotum, with the costal base of hemelytra less distinctly so, but more broadly and deeply behind the middle. Head short, pale brown above, the bucculae whitish; the eyes barely projecting beyond the line of the sides of pronotal prolongation ; antennae slender, fulvo-testaceous, dark at base, the apical joint more obscurely brownish, the second joint minute, tbe third as long as all the rest united, very slender, minutely ciliated, dark brown at base, the apical joint with long, erect setae ; rostrum flavo-testaceous, reaching to the middle coxae; a diagonal whitish streak beneath the eye. Pronotum tapering anteriorly, with the protuberance detached and lifted above the base of the head, becoming more compressed as it rises, and at the apex curved down beyond the head, its sides and dorsum each with a carinate line having series of large quadrangular cells between them, the lower border reflexed ; the posterior lobe of pronotum broad, a little convex, with the lateral margin expanded into a white, thin, reflexed border, which is bounded on the inner side by a raised thread ending anteriorly in a small button, the three longitudinal carinate folds white, arched, the intervening surface granulated; the carinate folds are continued back to tip of the scutellum, the lateral ones arched at base, fading out posteriorly, and the middle one low and slender throughout. Hemelytra mostly opaque, testaceous behind the middle, with the raised lines whitish ; the discoidal areole fusiform, fuscous behind, with the bounding veins carinate and the exterior one rising posteriorly; the surface generally granulated; a brown double spot occupies the space costally beyond the discoidal areole; costal area narrow, tapering at base, of almost equal width from thence to tip of membrane, whitish, provided with a single series of subquadrate areoles, and marked near the tip with a dark browni spot contiguous to a brown circle on the closed membrane, middle cells of the membrane large, unevenly reticulated, and with brown veins, the tip almost truncated.
