Vertex of medium length, convex in front, either pale fulvous, or yellow tinged with green, obsoletely marked with testaceous spots, a brown dot on each side of the summit,on aline with the paler brown ocelli; surface sericeous, not punctate, obsoletely incised on the middle; front narrow and scarcely one-half longer than width of base, the summit distinctly triangular, the lateral basal angles triangularly produced, emarginated beneath this, middle with a pale spot near the summit, and a long oval pale spot interiorly; superior cheeks dusky, spotted with yellow below the eyes, inferior cheeks yellow ; tylus yellow, with a brown stripe on the middle; the rostrum long, slender, testaceous, piceous at tip. Pronotum transverse, of medium length, moderately convex, scarcely scabrous, faintly sericeous, pale testaceous, marked with a triangular pale brown spot each side, two dots near tbe front margin, a line on the middle, and sometimes two small spots near the humeral angles ; the postero-lateral margins obliquely curved, the anterior margin regularly curved, causing the outer angles to be almost acute. Scutellum short, depressed and spoted on the middle, testaceous, with the tip acuminate. Legs dull testaceous, the apex of the tarsi, including the nails, piceous. Wing-covers faintly dusky; the veins, costal area, an angular mark on the tip of the basal areole, and a large oblong spot extending to the middle of the clavus yellowish white, the tip of this spot is bounded by a curved brown mark, the apical portion of the clavus dusky hyaline ; base of the corium, two faint spots beyond the basal areole, two others on the middle, the apical margin, and the tip of the clavus pale brown; wings dusky, with dark brown veins. Tergum black on the disk and base; middle of venter brown. Genital valve of male triangular, the following pieces wide at base, tapering toward the end. Length to tip of wing-covers 3|-3| m m . ; width of pronotum 1 mm. More than a dozen specimens, including incomplete states of coloration and texture of wing-covers, were taken at various localities on the island. Besides the foregoing species, the collection from St. Vincent includes several small Jassidce, related to Typhlocyba, Chlorita, Alebra, and Zygina, which cannot be satisfactorily determined for want of access to the types of tbe various authors who have described these insects. |
