Show 82 MR. M. JACOBY ON THE [Feb. 1, Easily distinguished by the densely rugose-punctate thorax and the cupreous margin of the latter and of the elytra. DERMORRHYTIS LEWISI, sp. nov. Greenish or brownish cupreous ; basal joints of the antennae and the legs obscure fulvous ; head and thorax closely and strongly punctured ; elytra strongly punctate-striate, the interstices trans-versly strigose throughout. Length 2g-3 lines. Head closely rugose-punctate, the epistome not separated from the face ; labrum fulvous. Antennse very slightly thickened at the apical joints, the third and fourth joints equal, the five or six lower joints fulvous, the others fuscous. Thorax transverse, the sides nearly- straight, the surface closely and strongly punctured, the interstices everywhere transversly rugose. Elytra subcylindrical, slightly narrowed behind, punctured like the thorax, but the interstices transversly raised and extending across the entire surface ; underside covered with fine silky-white pubescence. Dikoya. The straight sides of the thorax, in connection with the transversely rugose interspaces of the same part, and those of the entire disk of the elytra, will help to distinguish this species principally from D. piceipes, Baly. DERMORRHYTIS ORNATISSIMA, Baly. (Plate X. fig. 6.) Dermorrhytis fasciato-rutilans, Lefevre. Balangoda. This species, of which the two above names are synonymous, seems to vary greatly in regard to size and coloration ; all the specimens contained in m y collection are devoid of any cupreous spots on the thorax. In the present collection the specimens obtained by Mr. Lewis are much smaller, and have a broad transverse reddish-cupreous band occupying nearly the entire disk of the thorax. DERMORRHYTIS VARIABILIS, sp. nov. Greenish aeneous below ; above metallic green, the shoulders, sides, and apices of the elytra reddish cupreous; head and thorax remotely punctured, the interstices flat ; elytra punctate-striate, the sides transversely strigose ; basal joints of the antennae and the legs fulvous. Var. Above brownish cupreous. Length 2-2| lines. Head rather flattened, finely and moderately closely punctured, the interstices slightly rugose anteriorly only; the epistome not separated from the face, its anterior margin nearly straight; labrum fulvous. Antennse longer than half the length of the body, the five terminal joints slightly dilated, black, tbe others fulvous. Thorax nearly twice as broad as long, the sides straight and slightly subangulate or dentate; surface remotely and distinctly punctured, the interstices not raised. Elytra punctate-striate at the inner disk, irregularly |
