Hemelytra nearly three times as long as the width, translucent, the posterior margin straight; discoidal veins long, the middle one simple, the inner one forked behind the middle, the outer one twice forked next the membrane, the veins continuing this line across are oblique, and then straight in regular succession to the posterior margin ; cells of membrane mostly quadrangular, longer than wide. Posterior tibise with three spines behind the tip. TANGIDIA ALTEENATA, sp. nov. Pale fulvous, polished, broad, moderately flat. Head lined around the margins with white, and the triangle and oval reliefs of the sides of vertex also white; front pale yellow, the upper submargin black; eyes placed horizontally, long, oval, brown; rostrum extending to the middle coxse. Raised margins and carinate line of both pro- and mesonotum whitish. Costal areole long, wide, terminating in an acute pterostigma of dark brown colour; veins pale testaceous, interrupted by dark brown, the brown of the membrane most conspicuous on the apical margin and cross-veins; wings a little tinged with fulvous at base, the veins darker at tip. Sides of thorax streaked wdth pale brown, and a darker line runs back from behind the eye. Legs pale yellow; knees a little infuscated, the tips of spines black, and a short dark streak appears beneath the posterior knee. Venter greenish, broadly bordered with red, segments of the tergum obscurely banded with rufous and bordered with pale yellow. Length to tip of abdomen 4 m m . ; width between wing-covers If mm.; width of expanded wings 10 m m . Only one specimen of this neat insect was secured. BOTHEIOCEEA SIGNOBETI, Stal. Seven or eight specimens of the variety of this species, with the pale spot occupying most of the basal third of the corium, were collected at various localities on the island. BOTHEIOCEBA BICOENIS, Fabr. Seven specimens of this form were collected at different points on the island. They differ in minor details of marking from Brazilian and North-American specimens. This species is found also in Texas, Florida, North Carolina, Maryland, and N e w Jersev. In the last two States it is found in midsummer upon grass-like plants in the cranberry marshes. BOTHEIOCEBA UNDATA, Fabr. Ten specimens of several states of immature colourino- are present in the collection from St. Vincent. I find no structural differences to separate these from the foregoing species; and several specimens are so immature as not to have developed a pattern of marking. |
