Show 1885.] PHYTOPHAGOUS COLEOPTERA OF JAPAN. 729 versely wrinkled or finely rugose head, in connection with the suture of the elytra, which in shape agrees with L. atricilla, Gyll., but this species is smaller and has a blackish head. LONGITARSUS QUADRATICOLLIS, Sp. nov. Obscure dark fulvous ; antennae as long as the body; thorax subquadrate, impunctate ; elytra finely semipunctate-striate. Length \ line. Head impunctate, the frontal tubercles very narrow and transverse. Antennae flavous, the second and third joints short and equal. Thorax very nearly square-shaped, the sides straight, the anterior angles scarcely oblique, surface entirely impunctate. Elytra nearly parallel, but little narrowed behind, finely and rather regularly punctured. Legs flavous, the posterior femora darker, the metatarsus rather longer than half the tibiae. Nara. Amongst the small species of the present genus L. quadraticollis is somewhat closely allied to TJ. pusillus, but may be distinguished by the square-shaped and impunctate thorax. The elytra are larger at the base than the latter, and their shoulders are slightly prominent. LONGITARSUS LYCOPI, Foudr. The only difference I am able to find in the Japanese specimens from those of Europe is the slightly larger size of the former ; all other characters agree so closely that I see no reason to consider the two specimens obtained at Japan (Tisac 1) as specifically distinct. LONGITARSUS PARVULA ?, Allard. A single specimen resembling this species extremely closely was obtained; the elytra are rather more strongly punctured than in the European form. Genus APHTHONA, Chevr. A P H T H O N A FOUDRASI, sp. nov. Breast and abdomen piceous or black ; head and thorax pale fulvous, nearly impunctate ; elytra testaceous, very finely semiregu-larly punctate; legs testaceous, apices of the posterior femora piceous. Length | line. Head impunctate, dark fulvous, the frontal tubercles in shape of narrow transverse ridges. Antenna? rather short, flavous or testaceous, the four or five terminal joints fuscous. Thorax transverse, of equal width, twice as broad as long, the sides nearly straight, surface scarcely or microscopically finely punctured. Scutellum piceous. Elytra slightly narrowed behind, finely but distinctly punctured, the punctuation arranged in close, rather regular lines which almost entirely disappear at the apex ; the first joint of the posterior tarsi as long as the two following joints together. |
