Wing-covers slightly tapering, narrowly rounded at tip, with the veins and margins yellow, the apex more broadly dull yellowish; wings smoke-brown, with the veins darker. Tergum blue-black, pale at base, yellow on the sides, at tip, and on the edges of some of the segments; venter bright yellow posteriorly ; last ventral segment longer than the preceding one, a little wider behind, truncated. Length to end of venter, d1 3|, $ 4 m m . ; width of pronotum 1-1$ mm. Numerous specimens of this insect were taken in various parts of the island. This species varies in the size and form of the black dot on the front of vertex and in the number of yellow marks on the same. Occasionally the upper border of the front is also slenderly yellow. TETTIGONIA HEEBIDA, Walk. More than thirty specimens of this bright green species are in the collection from St. Vincent. This species is equally common in the islands of Cuba and Trinidad ; but we have not yet seen specimens of it from the mainland of South America. SCAPHOIDEUS STIGMOSUS, Sp. nOV. Pale fulvous; form similar to S. scalaris, Van Duz., but with a longer and wider head, and antenna? nearly as long as the wing-cover. Vertex a little longer than its width between the eyes, almost flat, very pale fulvous, with a series of brown dots around the anterior submargin and some less regular ones on the middle, occasionally with two or three ivory-white dots before the middle; front irregularly clouded with pale brown, bounded above by a slender dark brown line. Clypeus broad, bluntly rounded, marked with a brown subapical spot; the rostrum reaching to the middle coxa?. Eyes with a dark brown band below. Antennse dark brown, paler at base. Pronotum triangularly sublunate, well advanced into the deeply sinuated vertex, the surface minutely scabrous, transversely wrinkled, polished, dotted with pale yellow anteriorly, and minutely speckled with the same colour behind the middle; the posterior angles subacute, a little produced, the posterior margin slightly sinuated. Scutellum with a dark brown spot in the basal angles; the disk a little marbled with brown. Wing-covers marked with three brown spots on the inner margin of the clavus, each of which has an acute white spot at the tip; veins white interrupted with brown, margins pale ; the costal margin has a series of broader white streaks adjoining it inwardly, four large apical cells pale at base, bounded by brown veins, the apex a little dusky; wings smoky, with dark brown veins. Beneath and legs pale yellow, the tibia? somewhat marked with brown; the tarsal joints, nails, and spots at origin of the tibial spines dark brown ; the spines pale brown. Last ventral segment of the female deeply notched, the valves of ovipositor set with long, brown, stiff bristles; tergum blackish, with pale edges to the segments and a pale tip. |
