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 punctua- 

 tion 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 

 diffierent 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 pnuc- 

 tate-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, Hitoyoschi. (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. 

 Chrysomela cyrtonoides, 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 ; sur- 

 face very remotely punctured, the sides not thickened. Scutellum
