Show 1885.] PHYTOPHAGOUS COLEOPTERA OF JAPAN. 751 CLEROTILIA, n. gen. Body elongate. Palpi filiform ; eyes entire. Antenna? slender, longer than the body, the first joint club-shaped, the second short, the third and following double the length and nearly equal. Thorax transversely subquadrate without depression. Elytra finely semi-punctate- striate, impubescent. Tibiae unarmed ; metatarsus of the hind legs nearly as long as the three following joints together; claws bifid ; anterior coxal cavities closed. Elytral epipleura? continued to the apex. The bifid claws of this insect compel me to propose the present genus for its reception, which will enter the twenty-sixth group of Chapuis's arangement, the Platyxanthina, on account of the unarmed tibia? and closed anterior coxal cavities. The frontal tubercles are very strongly raised, and the antennae have the apices of their joints thickened. CLEROTILIA FLAVOMARGINATA, n. sp. (Plate XLVI. fig. 12.) Pale fulvous ; antennae piceous ; head and thorax impunctate; elytra very finely punctured, metallic green or blue, the lateral margin very narrowly flavous. Length 2 lines. Head not longer than broad, impunctate ; the frontal tubercles trigonate, strongly raised, divided by a narrow groove and bounded behind by another deep depression. Antennae distinctly longer than the body, piceous, shining, the first joint long, swollen towards the apex, second joint half the length of the third. Thorax one half broader than long, subquadrate, the sides narrowed at the base, the angles slightly tuberculate ; surface rather convex, without depression, impunctate, pale fulvous like the head. Scutellum of the same colour. Elytra finely alutaceous or granulate when seen under a strong lens, their surface closely and finely punctured, the punctuation arranged in indistinct rows ; green or blue, the extreme lateral margin fulvous ; epipleurae broad, extending to the apex ; legs entirely fulvous ; claws bifid, the inner division shorter. Tsumago, Nara. APPENDIX. NODOSTOMA VARICOLOR, sp. nov. Ovate, piceous ; antenna? and legs fulvous ; head, thorax, and the lateral margin of the elytra metallic green, the disk of the latter fulvous, punctate-striate. Length 1| line. Head finely and remotely punctured, the epistome not separated from the face ; eyes large ; labrum and palpi fulvous, iintennae half the length of the body, fulvous, second and third joints equal, the former thickened, the latter thinner than the following joints. Thorax transverse, nearly three times as broad as long, the sides very strongly rounded, but scarcely angulate behind the middle, strongly narrowed in front; surface metallic green, much more strongly |
