Show 1881.] ON NEW PHYTOPHAGOUS COLEOPTERA. 439 5. Descriptions of new Genera and Species of Phytophagous Coleoptera. By M A R T I N JACOBY. [Received March 5, 1881.] Genus LAMPROSPHSERUS, Baly. 1. L A M P R O S P H . E R U S GIGAS, sp. nov. Rotundate-ovate, convex. Metallic green ; base of antennae and the tarsi fulvous; thorax irregularly and rather finely, elytra more strongly, substriate-punctate. Length 3 lines. Hab. Peru. Head distinctly and rather closely punctured, with a central longitudinal groove; clypeus wedge-shaped, distinctly separated from the face, impunctate ; labrum and jaws black. Antennae two thirds the length of the body, the three basal joints fulvous, the rest black. Thorax transversely convex, its sides much narrowed towards the base, posterior margin oblique at each side, the median lobe but little produced; surface closely and irregularly covered with larger and smaller punctures. Elytra very convex, with a slight transverse depression below the shoulders, the latter rather prominent; surface strongly and rather regularly punctate-striate, less strongly towards the apex. Underside and legs metallic green, tarsi fulvous. In my collection. The large size of this species will distinguish it from the others described, L. tarsatus, Baly, being most nearly allied to it; from that species, however, the metallic green upperside and the strong punctuation of the elytra separate it. 2. LAMPROSPHSERUS SUBCOSTATUS, sp. nov. Rotundate-ovate, convex. Black ; base of antennse and the legs and tarsi fulvous; above dark blue, shining; thorax finely and closely, elytra deeply punctate-striate, the interstices laterally costate. Length 2 lines. Hab. Bogota. Head rugose-punctate ; labrum fulvous. Antennse subfiliform ; the last five joints slightly dilated, piceous; first five joints fulvous. Thorax three times as broad as long, sides evenly rounded, finely margined with metallic green, surface closely but rather finely punctured. Scutellum ovate, smooth. Elytra as wide as the thorax, narrowed and rather pointed towards the apex ; surface deeply and regularly punctate-striate, with three or four distinct costse near the lateral margin. Underside black ; legs entirely fulvous. Collection Jacoby. Genus P H S E D R A , Chapuis. 3. P H S E D R A B U C K L E Y I , sp. nov. Broadly ovate, subrotundate, convex. Below black; antennse, |
