Show 1903.] ON FISHES F R O M RIO JANEIRO. 59 with the usual ten rows of extremely closely placed punctures, the sutural row short, the interstices feebly convex and finely transversely aciculate ; the underside more metallic, the tarsi fulvous below, mesosternum scarcely raised, its epipleura? smooth; claw-joint simple, tibiae with longitudinal sulcus. Hab. Paraguay. This species is placed in the genus Leptinotarsa on account of the sulcate tibiae, which have the sulcus extending to half their length ; the colour of the antenna? and the slightly convex elytral interstices will easily distinguish the species. ELYTHROSPH^ERA CUPREATA, sp. nov. Ovate, pointed posteriorly, cupreous, variegated with metallic green ; antenna? black; thorax deeply and irregularly punctured ; elytra deeply foveolate punctate, the punctures arranged in rows, cupreous, the suture metallic green. Length 10 millim. Apterous ; the head finely punctured, with a central fovea, the vertex metallic green, the lower portion reddish cupreous ; labrum and palpi black ; antenna? rather long, black, the terminal two joints elongate, thickened, the basal joint metallic green; thorax one-half broader than long, the sides straight, the disc deeply foveolate and partly confluently punctured, cupreous, with a metallic green band at each side ; elytra very convex, widened at the middle, the apex pointed, each elytron with ten rows of fovea?, regularly placed, the sutural and lateral margins green, the disc cupreous; underside coloured like the upperside, the tibiae metallic green, the tarsi black. Hab. Rocco Nova, Parana, Brazil. Of this very distinct species a single specimen is contained in m y collection. 4. On a Collection of Fishes made by Dr. Goeldi at Rio Janeiro. By C. T A T E R E G A N , B.A. [Received April 28, 1903.] (Plates VII. & VIII.*) The collection of Fishes made at Rio Janeiro by Dr. Goeldi contains examples of one hundred and twenty-five different species, four of which are described below as new to science, one of these belonging to a new genus. As most of the species represented have been recorded either from Rio Janeiro or from not very distant points on the Atlantic coast of S. America, it would be superfluous to give the full list; in a few cases, however, the occurrence of a species at Rio Janeiro has been thought worth special notice, and the opportunity has been taken to add some notes and to give diagnoses where it seemed useful.
