Show PHYTOPHAGOUS COLEOPTERA. 7 in depth towards the apex, interspaces also minutely punctate, and from below the base to the apex closely and finely transversely wrinkled ; there is also an indistinct transverse depression below the base ; the ground-colour is a dark chestnut-brown; the disk, however, is almost entirely occupied by a broad piceous band, commencing below the base and extending to the apex, leaving only the sutural and lateral margins brown. Underside and legs of the same colour, abdominal segments margined with piceous, claws entirely of that colour. The hinder femora very short. This interesting Lema, of which I have at present only one specimen before me, will be easily recognized by the curiously shaped antennae and the sculpture of the elytra, although it is doubtless subject to variation in colouring. Genus URODERA, Lac. 4. U R O D E R A GODMANI, sp. nov. Oblong-ovate, black, shining, beneath closely pubescent. Head and thorax finely punctured. Elytra finely punctate-striate, black, a transverse band at the base, not touching the suture and the apex, rufous. Length 3-4 lines. Hab. Dueiias, Capetillo (Guatemala). Head with an obsolete transverse semicrescent groove between the eyes, distinctly but finely punctured. Antennae short, black, the second and third joints rufous, dentate from the commencement of the fourth joint. Thorax transversely convex, about twice as broad as long, its sides moderately rounded and greatly deflexed anteriorly, the lateral margins flattened and divided from the convex part by an oblique depression ; the flattened portion distinctly punctured and subrugose, rest of the surface very finely punctate, posterior margin oblique at each side, its middle lobe straight. Scutellum with a few extremely minute punctures. Elytra not wider at the base than the thorax ; each elytron with nine rows of punctures and a short double row near the suture black ; a transverse band, sinuate below the humeral callus and interrupted at a little distance from the suture, and an oblong apical spot rufous ; the latter spot does not quite touch the lateral margin or the suture. Underside closely covered with greyish pubescence ; anterior legs longitudinally sulcate at their inside ; prosternum very narrow. The punctured head and thorax will distinguish this speecis from others similarly marked, while the design of the elytra separates it from U. chevrolatii, to which it bears some resemblance; the thorax is also much more transverse than in the latter species. None of the specimens before me differ except in size from each other. Genus CHLAMYS, Knoch. 5. C H L A M Y S SEX-TUBERCULATA, sp. nov. Quadrate-ovate. Head, body below, and legs fulvous, spotted with violaceous; above violaceous blue, clothed with white pubescence, P R O C ZOOL. Soc-18/9, No. L. 50 |
