ON NEW SPECIES [Mar. 4, before the middle, the angles atnite, the basal sulcus very deep, straight, bounded at the sides by a perpendicular groove, the surface entirely impunctate; elytra much wider at the base than the thorax, the basal portion slightly raised, the disc very closely and distinctly punctured, the punctures arranged in indistinct rows, much finer towards the apex, a well-marked costa extends from the shoulders nearly to the apex and is preceded by a shorter one which does not extend upwards to the base, the interstices between these costae more irregularly and more strongly punctured than the rest of the surface, elytra! epipleurae broad, with a row of punctures; below and the legs metallic blue, impunctate, the last segment of the abdomen with a longitudinal groove which widens at the apex, the sides of the segment slightly raised. Hab. Venezuela. The single specimen before m e is probably a male, although the anterior tarsi are not particularly dilated. The species differs from its allies in the sculpture and costa? of the elytra, in connection with its coloration. DlPHAULACA FLAVIPES, Sp. n. Below piceous, above greenish-aeneous, the basal joints of the antennae and the legs entirely flavous; thorax impunctate, with deep transverse sulcus; elytra with the basal portion convex, scarcely perceptibly punctured except near the base. Length 4 millim. Head impunctate, aeneous, the frontal elevations small, ovate; antennae slender, blackish, the lower four joints flavous, the third and fourth of equal length ; thorax one-half broader than long, the sides straight at the base, rounded anteriorly, the angles acute, the disc deeply transversely sulcate, the sulcus sinuate, bounded at the sides by a perpendicular groove, entirely impunctate ; elytra widened towards the middle, the apex of each rounded, the base distinctly swollen, the shoulders prominent, the surface extremely finely punctured at the base, the punctures scarcely arranged in rows and very closely placed, nearly obsolete below the middle, the epipleurae very broad, concave; below obscure piceous, the legs entirely flavous. Hab. Colombia (Pehlke). Museum Stettin and m y collection. This small species may be at once known by the entirely aeneous upper surface and the flavous legs. The specimen before m e seems to be a female. DlPHAULACA PALLIPES, Sp. 11. Below black, above greenish-aeneous, the basal joints of the antennae and the legs (the posterior femora excepted) flavous; thorax impunctate, the basal sulcus deep ; elytra finely punctate-striate, the punctures indistinct near the apex. Length 2 millim. Head impunctate, the frontal tubercles narrowly oblique, the carina acute, the lower portion of the face and the labrum black, |
