Hemelytra long and rather narrow, the costal vein stout, clothed at base with stiff bristles. Venter smooth, plumbeous, with the genital pieces and the middle of the border of the apical segment orange. Length to tip of venter 3-3£ m m . ; width of pronotum 1| m m. Numerous specimens were obtained at Balthazar, August 7, at an altitude of 250 feet on running water; also on the Mount Gay estate, April 5, at the same altitude; and at Mount Maitland, August 20-25, at an altitude of 150 feet, on the surface of a stream of spring-water. 2. BHAGOVELIA ELEGANS, sp. nov. Larger and more robust than R. angustipes. Fuscous or dark rusty brown, hairy. The head short, across the eyes hardly wider than the front of pronotum, the callous ridge between tbe eyes not tapering posteriorly, almost touching the pronotuui ( $ ) ; the eyes wider apart, with tbe space between them broad, coarsely granulated, and destitute of* a callous ridge ( 3 )', the cheeks and most of the face yellow ; antennae of medium thickness, remotely set with long bristles, with the basal joint yellow at base, about one third longer than the second, the second a little less thick, much longer than the third, the third and fourth a little more slender, both contracted at base, the third with a slender tooth at tip, the fourth much shorter and acute on the apex ; the rostrum yellow, piceous at tip, reaching behind the anterior coxae. Pronotum stout, convex, coarsely transversely wrinkled, bordered all round with yellow, this colour covering the anterior lobe as a broad band and extending down over tbe pleura; the propleura constituting a thick aud broad callous smooth segment to carry the front legs, the surface behind this punctate in a curved line ; middle line obsoletely cari-nated, the posterior margin almost equilaterally triangular, with the edge recurved and the space before the tip usually depressed ; the humeral angle bluntly reflexed, obtuse, cut apart from tbe side below by an incised line ; pleura and sternum yellow, with piceous streaks running down upon the coxae. Legs stout, pubescent, dark brown, with the coxal plates mostly yellow; the posterior femora thick, clavate, tinged with bronze, polished, paler beneath, and armed there with about seven, chiefly long, teeth, of which the two inner ones are longer and thicker.

Length to tip of venter 4|-5 mm.; width of pronotum If-2 mm. The prothorax is much shorter and more blunt on the posterior margin in the unwinged individuals. Specimens of this form were met with at several localities. At Balthazar they were taken in April, on water; also on the |
