Show 1895.] HEMIPTEEA-HOMOPTEBA O F T H E ISLAND OF ST. VINCENT. 57 costal areoles each with a dark cloud, excepting the middle and inner ones; transverse border vein of the apex of the apical areoles, excepting the two outer ones, marked on the middle with a brown spot; the first apical areole long and wide, a little shorter than the third, and more than twice as long as the second, the second expanded at tip; the basal areole long, black at tip, and with the costal areole bordered above and below with black; apex of the clavus blackish. Breast invested all over with white flocculent matter accompanying the pubescence ; the opercula are broad, in contact on the middle line, a little angularly curved behind, and the extero-posterior margin reflexed and almost sinuated. Venter smooth, powdered with white, the basal segment of male composed of two thick ribs, which are sinuous each side and triangularly prolonged at base to fit into the emargination between the opercula. Tergum pubescent, sometimes spotted with fuscous on the sides, and banded with dark brown on the borders of the incisures; the basal segment of male often broadly white each side. Length to tip of venter, <3 22-23, $ 26-28 "mm.; to tip of closed hemielytra 34-43 mm. ; width of base of pronotum 9-11 mm. This species was taken at two or three localities on the island. Several specimens were secured which show marked differences in the ground-colour and extent of dark marking. Much of this is, however, due to degree of maturity and condition of the specimen at the time of capture. These, together with P. chariclo, Walker, and the allied green species with more dilated pronotum from Cuba, San Domingo, and Colombia, form a chain of connection between Odopcea and Tympanoterpes, Stal. The obliquity or curvature of the cross-vein of the second apical areole is too gradative to furnish a substantial separative generic character. This species, although closely related to P. chariclo, Walk., should not be confounded therewith. Besides the expansion of the pronotum and its different marking in P. chariclo, it has the dots of the apical series of areoles next the ends of the longitudinal veins, and not on the cross-veins as in our species. In this new species the basal areole is broader, the opercula close in contact, and the basal segment of venter not single. Fam. MEMBBACIDJE. The specimens of this family have not been sent to me for examination, and accordingly I can only judge of the value of the species described by Dr. Goding from a study of specimens secured in Grenada, Trinidad, and the Greater Antilles. The following list includes all the species reported by Dr. Goding from the island :- ENCHOPHYLLUM BILETI, Godg. Canad. Ent. xxvi. 1893, p. 56. Five individuals are recorded as having been collected in St. Vincent. |
