Show 554 MR. W. F. KIRBY ON THE [Dec. 4, accompanied the specimen, besides an empty pupa-skin, both probably belonging to the same species. FULGORID.E. RlCANIA FLAVICOSTALIS, Sp. n. Exp. al. 20 millim.; long. corp. 7 millim. Male. Head yellow, with four keels; vertex depressed, brown, except at the sides and on the median line; front quadricarinate, the angles of the outer carinae very prominent, the middle ones hardly projecting on the frontal edge ; all the carinae black, and with a short dark line on the clypeus between them, the middle ones rather wide apart, and meeting in a point at the extremity of the clypeus. Thorax and abdomen blackish brown above, the thorax tricarinate, varied with ferruginous on the sides and along the outer edges of the two outer carinae; abdomen with the second segment greenish, and the base of the three following segments ferruginous. Under surface of the body and legs yellowish ; the four front tibiae brownish above ; abdominal segments edged behind with a green line; the last two segments reddish brown. Wings hyaline ; fore wings with the costal space yellow as far as the black stigma, beyond which is a hyaline space; hind margin broadly purplish brown, intersected by a curved line nearly parallel to the hind margin; within the middle of this runs a narrow vitreous stripe covering the outer half of seven cells; one or two very irregular series of transverse cells beyond the middle of the wing, not even uniform on both sides; inner marginal region tinged with yellow, but less strongly than the costa; costal cross-nervures not forked, but most of the apical nervures beyond the stigma and on the hind margin are forked. Hind wings hyaline, brown along the hind margin, the first six or seven marginal nervures from the tip furcate or bifurcate. The neuration of this and the two following species somewhat resembles that of R. panorpceformis, Spin. No dates of capture are attached to any of the specimens. RlCANIA AFFINIS, Sp. n. Exp. al. 22 lin.; long. corp. 9 lin. Male. Very similar to the last species, but darker above, the brown bands on the clypeus beyond the inner carinae darker; under surface of body yellow, with irregular black markings beneath the wings, and a large spot on the pectus between the first two pairs of legs; abdomen not banded with green above, but with a row of yellow spots on the sides. Wings hyaline, not tinged with yellow on the costa or inner margin, but with a yellow spot on the costa (likewise edged with black within) before the black stigma; below the stigma are some small brown blotches along the line of the inner row of transverse cells ; there are also two small brown spots nearer the base on the lower half of the wing; hind margin brown for about one sixth of the width of the wing, and marked with two irregular hyaline spaces, each covering several cells ; close to the hind margin runs an interrupted row of small hyaline dots. Hind wings hyaline, |
