Show 1895.] HEMIPTEEA-HOMOPTEEA OF THE ISLAND OF ST. VINCENT. 65 truncated as viewed from above, the front of the vertex is, however, a little angular at tip and obliquely carinated each side, with the middle partly carinated, depressed • front curved outwards before the tip of vertex, long and wide, a very little wider than, and curved at the origin of, the epistoma, with the middle line strongly carinated and the lateral margins sharply reflexed, the epistoma tapering and continuing the gentle curve of the sides with the carina and reflexed margin ; cheeks wide, long, excavated, with the reflexed borders rising prominently above the eyes. Basal joint of antennse subglobose as usual. Pronotum very short, the front edge upturned, with the sides curved, but little wider, and ending below in a slight enlargement. Mesonotum a little wider than the length including the scutellum, the sides expanded triangularly, but the medial shield narrow, almost square, carinated on the middle, and bounded by a carina on each side, the scutellum acutely triangular, a little reflexed like the wings of the preceding segment. Wing-covers narrow, a little bent at tip, with the inner apical corner angular, shorter than the upper which is curved; costal area long and narrow, expanded at tip in contact with the ovate nodal cell, its middle a little acute where the anastomosis of the first fork occurs, the first ulnar areole starting from a fork beyond the middle of the costal area and extending in a slight curve to the nodus, the second one starts iu a fork near the base, and continuing sends off a vein from a blunt fork on a line with the nodus, at this point three oblique cross-veins form the base of the middle anteapical areoles; the apical areoles longer, narrow, seven in number, of which the anterior one is very short and triangular, while the posterior one is very long and wide and ending in an acute, somewhat curved angle. Posterior tibise destitute of any apparent spine. AMBLYCEATUS PALLIDUS, sp. nov. The body relatively broader, but the wing-covers narrower, and not obliquely expanding towards the tip as in the foregoing genera. Colour pale fulvous, tinged with pale testaceous. Head almost square, as seen from above, with the blunt triangle of the tip of vertex on a line with the front of eyes, powdered with white; the eyes brown, somewhat bean-shaped; antennse pale fulvous; summit of front and a faint band across its middle dusky; epistoma also a little dusky. Rostrum reaching to behind the posterior coxse. Wing-covers whitish yellow, or very pale fulvous, with the costal vein mostly brown, the nodal spot whitish, aud the apical anterior margin of the membrane pink ; veins of the ulnar areole, an oblique streak at base, the posterior border and two lines ou the clavus, the posterior edge of the membrane and the coarse vein next inwards, and a broad uneven spot across the apical half of the membrane smoke brownish; the transverse veins of m e m brane whitish. Underside and legs testaceous, with a tinge of plumbeous ; tip of the venter dark brown. Disk of mesonotum and surface of tergum dark brown. P E O C . Z O O L . Soc-1895, N o . V. 5 |
