Show lo/y.j PHYTOPHAGOUS COLEOPTERA. 787 near the base; surface impunctate, very shining, flavous, the disk near the base deeply but irregularly transversely foveolate. Scutellum flavous. Elytra wider than the thorax, very bright metallic green, closely and rather coarsely rugose-punctate ; tibiae and tarsi black, first joint of latter longer than the following joints together. Claws appendiculate. This species seems to form a connecting link between the genus Scelida of Chapuis and the present one; it miy with equal right be classed amongst the first on account of the unarmed tibiae and other characters ; but as in Scelida the third joint of the antennae is much longer than the second, while here it is as short, I have included it in the present genus, although it differs from the typical species in not having the joints of the antennse dilated. Genus SCELIDA, Chapuis. 27. S C E L I D A VIRIDIS, sp. nov. Elongate, parallel. Metallic green, pubescent below ; head, thorax, antennse, and legs flavous ; elytra closely rugose-punctate, metallic green. Length 6 lines. Hab. Mexico. Head elongate, vertex swollen, with a deep fovea in the middle, apex of jaws piceous; antennae half the length of tbe body, the second joint short, the fourth slightly longer than the third. Thorax nearly square, its sides, from the middle to the base, nearly parallel; surface impunctate, with a deep oblique fovea at either side. Scutellum flavous. Elytra much wider tban the thorax, parallel, closely rugose-punctate. Underside metallic green, the sides of the breast and the posterior margins of the abdominal segments closely covered with long white hairs. Legs entirely flavous. Of the two other described species, £. elegans, Chapuis, and S. balyi, Jacoby, tbe present one will be easily recognized by its green underside and the entirely flavous antennse and legs. Genus MONOTIA, Le Conte. 28. M O N O T I A VIRIDIS, sp. nov. Oblong-ovate, convex. Obscure flavous beneath ; above dark olive-green, opaque, finely punctate and pubescent. Length 4 lines. Hab. Zapote, Guatemala. Head with a longitudinal middle groove, rather deeply and closely punctured, clypeus narrow, transverse; labrum obscure piceous : autennse about half the length of the body, tbe basal joint olive-green, the following joints testaceous, the last three piceous or black ; the first and fourth joints are of equal length, the second half the size of the third. Thorax transverse, sides slightly an-gulate before the middle ; surface obsoletely impressed near the anterior and lateral margins, finely and not distinctly punctured. |
