Show 1895.] HEMIPTEEA-HOMOPTEEA OF THE ISLAND OF ST. VINCENT. 79 minute specks ; cheeks partly bordered each side with pale green ; rostrum pale greenish, short, black at base. Legs pale yellowish, the inside and tip of posterior tibise and bands on the tarsal joints brown. Wing-covers smoke-fuscous, pale on the centre of all but the apical cells; costal border ivory-yellow, including two short black stripes near its tip, following which the superior apical cell is black, and the next below only a little less deep black, the inferior one still paler, these three bounded on the sides by brown veins, the other veins pale yellow; areoles of the clavus each with a dark brown stripe on the inner border; wings faintly smoky, with dark veins. Pronotum short, broadly curved in front, polished, minutely wrinkled, marked anteriorly with a transverse series of yellow dots, sometimes provided with five incomplete pale stripes ; the dorsolum bordered with a square yellow lineation, followed directly behind by the triangular scutellum margined also with yellow. Abdomen brownish or black, the segments generally with pale edges, and the male usually darker than the female. The superior genital pieces of the male nearly triangular, the inferior ones uniting to form a longer subacuminate triangle bordered with yellow; the valvular segment at base of these is triangular and a little curved on the sides ; genital pieces all armed with brownish long bristles. Length to tip of wing-covers 2|-3 mm.; width of pronotum 1-1 $ mm. Five specimens of this odd little species were taken at various places on the island. It is a common North-American form which is distributed all the way from Florida, along the coastal plain, to northern N e w Jersey. It varies much in depth and extent of colour, and somewhat in the degree of bluntness of the tip of vertex. In Maryland it rests upon the leaves of bushes and occurs from August to October in sunny situations. DELTOCEPHALUS CUNEATUS, sp. nov. Robust, brownish or black, marked with pale green above. Form similar to the preceding species. Vertex bluntly rounded, a little longer than wide between the eyes, yellowish green, marked anteriorly with two large black dots, and farther back with two minute ones; eyes large, not prominent, but extending far back to complete the deep sinus of the occiput; front long, moderately convex, with two broad stripes, which occupy most of the width or are interrupted by oblique bands : clypeus with a black dot each side ; the rostrum short, fulvous. Pronotum very short, lenticular, pale green, with an anterior impressed blackish submargin. Scutellum bluntly carinated on the middle, marked with black before the middle, and twice indented there. Coxa? mostly black ; femora and tibise dull testaceous, obscurely striped with brown, the tarsal joints more or less marked with brown. Pleural segments blackish, partly marked with green ; wing-covers a little curved on the costal margin; the clavus pale green with a brown edge on both margins, the costal area also green, this colour some- |
