Show 1885.] PHYTOPHAGOUS COLEOPTERA OF JAPAN. 721 punctured at the disk, the latter with a more or less distinct central longitudinal smooth space, the sides at the base impressed with a short but deep fovea. Scutellum extremely small. Elytra convex, subcylindrical, the punctuation strong and regularly striate, the interspaces not raised. Legs entirely fulvous. Kumamoto. The small and convex shape of this species, in connection with the strong and close punctuation of the thorax and the entirely fulvous legs, will assist in separating it from its allies. The sides of the thorax are also much more rounded and dilated than in any species with which I am acquainted. Genus CREPIDODERA, Chevr. C R E P I D O D E R A LEWISI, sp. nov. Oblong, fulvous ; terminal joints of the antennae, apices of the femora, tibiae, and tarsi black. Thorax impunctate. Elytra extremely finely punctate-striate. Length 2-2? lines. Head impunctate, the frontal tubercles broad, divided anteriorly only, contiguous posteriorly ; carina acutely raised ; labrum and palpi obscure piceous. Antennae half the length of the body, the four lower joints fulvous, the rest black, third and fourth joints equal in length, one half longer than the second. Thorax not more than one half broader than long, the sides very slightly rounded, the angles distinct but not produced, the anterior ones slightly oblique, the basilar sulcation broad and moderately deep, but bounded at the sides by a deep longitudinal groove, the upper end of which extends slightly beyond the sulcation ; surface entirely impunctate. Elytra slightly broader at the base than the thorax, very minutely and rather irregularly punctate-striate, the punctured rows rather distantly placed and often consisting of double punctures, the apex scarcely visibly punctured. Legs and tarsi black, the base of the femora fulvous. The exact locality of this species, which belongs to the group including C. transversa, C. impressa, &c, is not given. It may be that C. lewisi is identical with C. obscuritarsis, Motsch., or at all events closely allied, but the colour of the antennae and legs is different. The punctuation of the elytra is rather variable, consisting in more or less closely approached extremely fine rows of punctures, which here and there are united in pairs but for the most part single and irregularly placed. The species may be recognized principally by the colour of the antennae, which have the four first joints fulvous only, the rest being black, the latter colour being that also of the tibiae and tarsi. CREPIDODERA RECTICOLLTS, sp. nov. Oblong-ovate, narrowed behind, entirely pale fulvous; thorax impunctate, the sides straight; elytra finely punctate-striate. Length 1 line. |
