Show 778 MR. M. JACOBY ON NEW [Uec 10, longitudinal smooth costse which unite near the apex, the outer one being placed close to a longitudinal sulcation which runs parallel with the lateral margin ; the interstices are more or less distinctly transversely rugose. Underside closely silvery pubescent, legs fulvous, last joint of tarsi piceous. Genus PRIONODERA, Chapuis. 9. P R I O N O D E R A G O D M A N I , sp. nov. Elongate. Testaceous ; antennse with joints 5-7 and 10-12 black ; elytra coarsely punctate and subrugulose, each elytron with a spot at the base and one near the apex metallic green. Length 4| lines. Hab. Zapote, Guatemala. Head deeply but not closely punctured, with a shallow fovea between the eyes ; antennae two thirds the length of the body, testaceous, from the fifth to the seventh and the three apical joints black. Thorax nearly twice as broad as long, its sides tridentate, the posterior tooth obsolete and more rounded, the anterior ones acute and distinct ; surface rather convex, closely but not more deeply punctured than the head. Scutellum smooth. Elytra wider at the base than the thorax, deeply and coarsely but irregularly punctured, the puncturing near tbe suture, however, more regularly striate; the interstices coarsely rugose and transversely wrinkled at the base and near the apex, tbe latter also distinctly costate, each elytron with two large metallic green patches, one of which, situated at the base, is of a semitriangular shape with its inner margin obliquely cut; the other patch is placed below the middle, of a more rounded shape; neither of them extends to either the lateral or sutural margin. The entire underside and the legs testaceous. Several similarly coloured species have been described, from all of which the present one is distinguished by the colour of the antennae, which is constant in all the specimens before me, as well as by the shape and margination of the thorax and the colour of the elytral spots. Collected by Mr. G. Champion. Genus FIDIA, Baly. 10. FIDIA G U A T E M A L E N S I S , sp. nov. Subcylindric, elongate. Bronze-coloured, closely covered with white pubescence ; thorax deeply punctate; elytra coarsely punctate- striate, the interstices costate. Length 2-3 lines. Hab. Dueiias, Capetillo (Guatemala). Head strongly punctate, with a short longitudinal groove in the middle; eyes entire, convex; antennse longer than half the body, black, with a greenish hue on the surface of the basal joints, the latter fulvous below; the first six joints (with the exception of the short second joint) slender, filiform, and of nearly equal length, the rest much thicker.
