1895.] HEMIPTEBA-HOMOPTEEA OF THE 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 tlocculent 

 matter accompanying the pubescence ; the opercula are broad, in 

 contact on the middle line, a little angularly ciu-ved 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 

 incisui-es ; the basal segment of male often broadly white each side. 



Length to tip of venter, c? 22-23, $ 26-28 "mm.; to tip of 

 closed hemielytra 34-4.S 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 wliich 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. cJunich, Walker, 

 and the allied green species with more dilated pronotum from 

 Cuba, San Domingo, and Colombia, form a chain of connection 

 between Odopcea and Tympunoteiycs, StSl. 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. charich, Walk., 

 should not be confounded therewith. Besides the expansion of 

 the pronotum and its different marking in P. charido, 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. Membracid jI;. 



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 ; —

Five individuals are recorded as having been collected in St. 

 Vincent.
