740 MR. M. JACOBY ON THE [NoV. 3, 



scarcely visibly punctured and granulate. The elytra are very 

 deeply punctate- striate, and the striae are more closely placed than 

 in the other Japanese species ; the interstices are convex at the sides, 

 and obsoletely transversely wrinkled ; the legs are entirely piceous. 

 P. diffiiilis, Ealy, which has also convex elytral interstices, is much 

 laiger, and of a bright metallic blue, the thorax is distinctly punc- 

 tnred, and the elytral striae are more finely impressed and more 

 distantly placed. 



PSYLLIODES JAPONICA, Sp. nOV. 



Oblong, black below ; antennae, the anterior legs, and the posterior 

 tibise flavous ; above dark metallic green ; vertex impunctate ; 

 thorax closely pnnctured ; elytra strongly punctate-striate, the inter- 

 stices finely punctured. 



Length 1 line. 



Head extremely finely granulate, impunctate, with a narrow but 

 deep oblique groove at each side above the antennse, the space 

 between the latter broad and slightly raised. Antennae entirely 

 flavous, the second joint slightly longer than the third. Thorax 

 twice as broad as long, the sides nearly straight, surface extremely 

 finely granulate, closely and finely punctured. Elytra narrowed at 

 the apices, strongly and regularly punctate-striate, the interstices 

 with a single row of fine punctures, somewhat raised near the apex. 



Sapporo. 



Bather smaller than P. angusticollis, Baly ; the head and thorax 

 differently punctured and granulate, and the elytra more strongly 

 punctate-striate, with the interstices not impunctate as in that species, 

 but with a single row of punctures ; another different structural 

 character is the oblique groove at each side above the antennae. 



Genus Enneamera, Har. 

 Enneamera tibialis, sp. nov. 



Black ; antennae fuscous ; elytra dark greenish blue, closely punc- 

 tured ; four anterior legs, base of the posterior femora, abdomen, 

 and the tibiae and tarsi fulvous or testaceous. 



Length Ig-lf line. 



Head with a few very fine punctures, the frontal tubercles limited 

 behind by a deep transverse groove. Labrum piceous. Antennae 

 obscure fuscous or fulvous, the third joint distinctly longer than the 

 second. Thorax more than twice as broad as long, black, extremely 

 finely punctured, the anterior angles obscure fulvous. Scutellum 

 black. Elytra convex, scarcely widened below the middle, their 

 surface very finely and closely punctured. 



Jensai, Eukushima, Nikko, Nara. 



Easily distinguished from E. cyanea, Baly, and E. fiilviventris, 

 Baly, by the black, not blue, thorax, and the colour of the anterior 

 legs and all the tibiae, as well as by the obscure fulvous antennae. 

 Nine specimens were obtained.
