Show 1887.] PHYTOPHAGOUS COLEOPTERA OF CEYLON. 79 A single specimen (coll. Jacoby). N. lefevrei differs from N. tuberosum in the much more transversely shaped and finely punctured thorax, the strongly costate elytra anil their coloration. NODOSTOMA CLYPEATUM, sp. nov. Pale testaceous; apical joints of the antennae fuscous; clypeus strongly punctured ; thorax angulate below the middle, strongly punctured at the sides only ; elytra with basal depression, the latter distinctly, rest of the disk nearly obsoletely, punctured. Length 1 line. Head nearly impunctate at the vertex ; the epistome strongly but very remotely punctured, not separated from the front; the space above the insertion of the antennae obliquely grooved. Antennse slender, nearly as long as the body, testaceous, the three or four terminal joints fuscous or black. Thorax twice as broad as long, strongly narrowed in front, the sides distinctly angulate near the base, surface without an anterior groove, strongly punctured at the sides only, the middle of the disk with a few fine punctures only. Elytra with a very distinct subbasilar depression, the base itself with a few remotely placed punctures arranged in lines which extend more or less distinctly to the middle ; below the latter the punctuation is almost entirely wanting; femora with a minute spine. Galle. Principally distinguished by the nearly impunctate vertex, the strongly punctured epistome and sides of the thorax, in connection with its general small size ; the absence of a transverse anterior groove at the thorax will further assist in the recognition of N. clypeatum. NODOSTOMA LONGICORNE, sp. nov. Fulvous; legs testaceous, the knees obscure piceous ; antennse as long as the body ; thorax very finely punctured, angulate behind the middle ; elytra strongly punctate-striate, with basal depression, the lateral margins anteriorly black. Var. Elytra entirely fulvous. Length 2-2| lines. Head finely and rather remotely punctured; the epistome separated from the front by a slight transverse depression, with a few deep punctures ; palpi testaceous. Antennae as long as, or slightly longer than, the body, fulvous, the apical joint darker, the fourth joint rather longer than the third. Thorax transverse, strongly narrowed in front, the sides distinctly angulate near the base, the surface with a deep and punctured transverse sulcation near the anterior margin, very finely and rather remotely punctured, the lateral margin narrowly piceous. Elytra not broader at the base than the thorax, with a deep subbasal depression, verv strongly and deeply punctate-striate anteriorly, more finely towards the apices, the interstices slightly convex, more distinctly so at the sides, the lateral margin anteriorly rather broadly piceous or black, this colour extending slightly across the elytral |
