Show 887.] PHYTOPHAGOUS COLEOPTERA OF CEYLON. 101 testaceous; thorax metallic blue or greenish, finely punctured; elytra metallic purplish or cupreous, closely punctured. Length 1 line. Head impunctate ; the frontal tubercles feebly raised. Antennse black, tbe last seven joints transversely dilated, "the others obscure testaceous. Thorax transversely subcylindrical, widened towards the middle, the surface finely granulate and punctured, with an obscure longitudinal impression near the lateral margin. Scutellum triangular, piceous. Elytra very convex, narrowed behind, of a reddish metallic cupreous colour, very closely and irregularly punctured. Legs black, the tibise rather lighter, the posterior ones armed with three or four teeth ; their apices with a long fulvous spine ; claws appendiculate. Bogawantalawa. This species is of the same shape as the preceding, with which it has further all the structural characters in common ; the different coloration sufficiently distinguishes it. IVALIA FULVIPENNIS, sp. nov. Black; head and thorax impunctate; elytra dark fulvous, very closely and irregularly punctured. Length 1 line. Head broader than long. Antennse short, robust, the three lower joints obscure fulvous, the rest black. Thorax three times as broad as long, the sides nearly straight, surface entirely impunctate, black. Scutellum black. Elytra rounded, very convex, dark reddish fulvous, closely punctured, the interstices somewhat rugose or wiinkled. Legs piceous, the tibiae more or less obscure fulvous. DEMARCHUS (gen. nov. Halticinorum). Body ovate; pubescent. Antennae filiform, the third joint more than double the length of the second; palpi robust. Thorax transverse with an anterior and posterior transverse depression. Scutellum subpentagonal. Elytra pubescent, finely rugose, their epipleurae disappearing below the middle. Tibise simple, unarmed; the first joint of the posterior taisi not longer than the second ; claws obsoletely bifid. Anterior coxal cavities open. Prosternum scarcely visible. Mesosternum narrow and pointed. The single specimen before me, upon which I am obliged to establish the present genus, resembles in general appearance a species of the genus Sebaetha, from which the simple tibiae, transversely impressed thorax, and the pubescent elytra will at once distinguish it. The posterior femora are moderately but very distinctly incrassate. D E M A R C H U S PUBIPENNIS, sp. nov. Testaceous; head rugose; thorax shining, nearly impunctate; elytra obscure fulvous, the basal and the lateral margin obscure piceous. Len°-th 2 lines.
