Show 718 ON HEMIPTERA-HETEROPTERA FROM ST. VINCENT. [Nov. 21, rounded and with a curved spur above in the male; the outer angle of the dorsal segments is more or less toothed. Length to end of abdomen 18-19 millim.; width of front of pronotum 1 millim.; width of last segment of abdomen 1£-1§ millim. Several specimens of both sexes were secured at various places on the island. Only unwinged ones were found, and three or four of these are in the younger stages. These nymphs are essentially like the adult and differ more in size than in the elements of structure. The form of pronotum and abdomen with the accompanying teeth is nearly the same as in the full-grown specimens. One specimen was found on the leeward side of the island, in September, at an altitude of 2000 feet, and others were captured under logs on'the Richmond estate, leeward, in an open valley near sea-level, on October 31. In m y collection there are specimens from the vicinity of Panama. EMESOPSIS, gen. nov. Form similar to that of Ploiaria, Scop., agreeing therewith especially in the form of the head, but differing in the venation of the hemelytra. Head wide and short, tumidly convex behind, the transverse stricture crossing between the eyes; the throat unarmed. Rostrum reaching between the anterior coxae; the basal joint stout, extending behind the line of the eyes ; the second shorter, tumid; the third slender throughout, shorter than the basal one. Antennse almost setaceous, the basal joint a little stouter, about as long as the head and pronotum united; the second and third shorter, subequal. The eyes subglobular, placed below the level of the vertex. Anterior tibiae and tarsi together scarcely shorter than the femora, the femora apparently armed with fine spines throughout nearly the entire length. Pronotum short, the posterior lobe more than twice as long as the anterior one, tumidly convex behind; the anterior lobe very short, elevated into a callosity each side. Scutellum small, distinct, conical at base, constricted behind, the narrowed portion evenly cylindrical to the tip. Hemelytra membranous throughout, gradually widening towards the tip, the costal margin straight to beyond the middle ; veins of the corium sharply distinct, the transverse ones few, crossing at nearly right angles, the cells growing larger posteriorly, the apex with a triangular narrow cell at both the outer and inner angle ; cells of the membrane large, the basal one longest, ending in a protracted narrow loop, which sends off a vein to the tip. Abdomen moderately flat, widened towards the middle. EMESOPSIS NUBILUS, sp. nov. Pale f ulvo-testaceous, elongate, but not linear, smooth above, pilose over most of the surface. Head obsoletely, minutely punctate, the transverse impressed line and a small spot on the middle brown. Antennae setaceous, the last joint infuscated; eyes fuscous. Legs pilose, the intermediate and posterior femora |
