Show 206 MR. M. JACOBY ON NEW [Feb. 17, to vary except slightly in size. The species has the same coloration as N. davidi, Lefevre, from China, but differs in the strong punctuation of the thorax. In N. balyi, Har., the punctuation of the latter is much more closely placed, and the shape of the insect is quite different as well as its colour. NODOSTOMA MODESTUM, sp. nov. Ovate, subquadrate, convex, entirely metallic dark blue ; the second and third joints of the antennae fulvous; thorax finely and remotely punctured ; elytra depressed below the base, finely punctate- striate. Length 2 lines. Head irregularly but rather deeply punctured, especially anteriorly, the epistome not separated from the face. Antennae rather more than half the length of the body, the basal joint metallic blue above, the following two fulvous, the rest black, the second joint of curved shape, nearly as long as the third. Thorax not more than twice as broad as long, the sides with a distinct tooth near the middle; surface with a rather deep transverse fovea at each side, distantly but deeply punctured, the punctures more deeply impressed at the sides than at the disk. Scutellum black, impunctate. Elytra with a deep transverse depression below the base and another longitudinal one within the shoulders, finely and regularly punctate-striate at the inner disk, more strongly and closely near the sides ; within the basal depression a few transverse wrinkles are visible. Underside and legs entirely dark blue ; all the femora armed with a minute tooth. Tarsi black. Yuyama, Hitoyoscbi. (12 specimens.) It is impossible to say whether one of Motschulsky's short and insufficient descriptions is meant for the present species, which is of the same size as N. balyi, but differently sculptured and of a uniform violaceous blue colour. The small tooth at the sides of the thorax is placed nearer the middle than is often the case in other species of this genus. Genus CHRYSOMELA, Linn. C H R Y S O M E L A C Y R T O N O I D E S , sp. nov. Ovate, very convex, widened behind, brownish aeneous ; thorax distantly punctured ; elytra rather closely punctate-striate, the interstices smooth and impunctate. Length 2-2^ lines. Head convex at the vertex, entirely impunctate; epistome separated from the face by a deep arcuate groove. Antennae half the length of the body, rather robust, the first joint broadly dilated, the third joint not more than one half longer than the preceding, the rest gradually thickened, black, the basal joints tinged with aeneous. Thorax very convex, the sides rather strongly deflexed, the lateral margin but slightly rounded, angles not pointed but distinct ; surface very remotely punctured, the sides not thickened.
