Show 180 MR. M. JACOBY O N N E W [Mar. 2, 29. (EDIONYCHIS ABBREVIATA, sp. nov. Broadly ovate. Fulvous ; elytra distinctly punctured, fulvous or flavous, a broad transverse basal band and two others behind the middle, none of them touching the lateral margins, violaceous blue. Var. The posterior bands united into a large patch. Length 3|-4 lines. Hab. Amazons. Head with a few distinct punctures at the vertex and a deep fovea in the middle ; antennae entirely fulvous or piceous, with the first three joints fulvous. Thorax about three times as broad as long, its sides broadly flattened, anterior angles produced into a blunt tooth, surface minutely punctured ; scutellum fulvous. Elytra closely punctate, longitudinally impressed within the humeral callus ; surface rather convex, with three violaceous blue bands across the disk, the two posterior ones of which are closely approached and narrower than the basal one. Underside and legs fulvous. This species seems closely allied to bifasciata, Baly; but the antennae and apex of the posterior femora are described as black, and only two elytral bands are mentioned. It may, however, turn out to be a variety of Baly's species. Three specimens in m y collection. 30. (EDIONYCHIS MARGINICOLLIS, sp. nov. (PlateXVIII.fig.il.) Oblong-ovate, convex. Black below (tarsi excepted), above violaceous blue ; sides of the thorax and a narrow sutural and marginal vitta of the elytra, united at the base and apex, flavous. Length 3 lines. Hab. Rio Janeiro. Head deeply punctured at the vertex, about as broad as long; eyes prominent; antennae black, the two basal and the apical joints fulvous. Thorax comparatively broad, sides flattened and evenly rounded ; anterior angles acute, but not produced into a tooth ; surface impunctate, black, lateral margins flavous. Elytra convex, widened behind the middle, strongly punctured at the base, less so towards the apex; each elytron with a curved, narrow, longitudinal vitta near the suture and the lateral margin flavous ; the sutural vitta forms a continued line with the flavous thoracic margin, and unites at the base and the apex with the lateral band, the space between the two bands being widest in the middle of the elytra; epipleurae of the latter also flavous. Underside and legs black ; extreme apex of the tibiae and the tarsi fulvous. Type in m y collection. At first sight this species seems closely allied to cosmogramica, Harold ; but the punctuation of the elytra and the coloration of the legs and antennae distinguish it. 31. (EDIONYCHIS SEX-PLAGIATA, sp. nov. (Plate XVIII. fig. 12.) Oblong-ovate. Fulvous ; above flavous; disk of thorax, the suture, and three transverse bands on each elytron fulvous. Length 3-J lines. |
