Show 1887.] PHYTOPHAGOUS COLEOPTERA OF CEYLON. 107 probably to discoloration. At once distinguished from G. ceylonensis by the much more transverse and finely punctured thorax as well as by the uniform obscure, not metallic green, colour of the elytra. GALERUCELLA CROTCHI, sp. nov. Obscure testaceous, finely pubescent; the head with one, the thorax with three fuscous spots; elytra metallic green, finely rugose and pubescent, the sutural and lateral margin narrowly purplish. Length 2\ lines. Head minutely punctured, with an indistinct central longitudinal groove, the vertex with an obscure large fuscous spot. Antennae half the length of the body, testaceous, the terminal joints stained with fuscous, the third joint shorter than the fourth. Thorax twice as broad as long, the sides rounded, narrowed at the base, surface finely pubescent, with an obsolete transverse lateral and a deeper longitudinal central depression, the sides and the central groove fuscous. Scutellum fuscous. Elytra covered with rather long grey pubescence, bright metallic green, narrowly margined with purplish, the surface finely rugose-punctate. The tibise unarmed, the first joint of the posterior tarsi nearly as long as the two following joints together. Claws bifid ; anterior coxal cavities open. Galeruca anescens, Fairm., from Central China, seems to be closely allied to the present species, but differs in the equal length of the third and fourth joints of the antennse and in the traces of longitudinal costse of the elytra, also in the different shape of the thorax. GALERUCELLA MARGINATA, sp. nov. Obscure testaceous ; antennse, tibiae, and tarsi black ; head and thorax strongly punctured, shining, the thorax with five black spots ; elytra very finely punctured and pubescent, obscure testaceous, a narrow longitudinal stripe near the lateral margin blackish. Length 3| lines. Head closely rugose-punctate, the vertex obscure fuscous. Antennse more than half the length of the body, black, slender, the third joint the longest. Thorax more than twice as broad as long; the sides subangulate at the middle, the anterior angles slightly dentate; the surface closely impressed with larger and smaller punctures, the sides with a deep round fovea, the middle with an obscure longitudinal depression, the latter of black colour, a similar-coloured spot is placed close to the lateral margins, making in all five spots placed transversely across the disk. Elytra rather convex, very finely and closely punctured and covered with short whitish pubescence; a narrow lateral stripe commences at the shoulder and is abbreviated a little distance from the apex of each elytron; the first joint of the posterior tarsi as long as the two following joints ; claws bifid. A single specimen. XENARTHRA MIRABILIS, sp. nov. (Plate XI. fig. 9.) Elongate, parallel; subdepressed, testaceous; antennse piceous, pectinated, 12-jointed ; head with three, thorax with five piceous |
