Show 1885.] PHYTOPHAGOUS C O L E O P T E R A O F JAPAN. 747 with the posterior margin); the interstices swollen or irregularly raised, covered, as well as the interior of the impressions, with deep punctures. Scutellum piceous or fulvous, its apex broadly rounded. Elytra not widened behind, rufous or sanguineous, like the head and thorax; each elytron with eight strongly raised and closely approached costae, the space between the first costa and the suture of double the width between the others, the interstices very deeply and regularly impressed with round punctures. Underside and legs black, finely covered with sparing yellow pubescence ; the femora and knees sometimes obscure fulvous; anterior coxal cavities closed ; claws appendiculate. Kiga, Konose, Jchiuchi, Suyama on lillies. From any of the similarly coloured European species, A. multi-costata is at once to be separated by the eight closely approached costa?, which leave a broader space only between the first and the sutural margin. Genus G A L E R U C I D A , Motsch. G A L E R U C I D A LEWISI, sp. nov. (Plate X L V I . fig. 6.) Black ; thorax foveolate-punctate ; elytra closely and very deeply semipunctate-striate ; a spot at the shoulder, a transverse narrow sinuate band behind the middle, and a round spot near the apex yellow. Length 3 lines. Head impunctate ; antenna? more than two thirds the length of the body, the second and third joints very short and equal. Thorax transverse, sides nearly straight, slightly widened in front, the anterior angles produced in shape of a small tubercle, surface irregularly covered with deep foveolate punctures. Scutellum impunctate. Elytra very deeply and rather closely punctured, the punctures arranged in semiregular rows and sometimes confluent; the small yellow spot placed at the shoulder smooth and raised, the transverse band below the middle sinuate and not extending to the suture, the apical spot round and small. Oyama. This species, of which many specimens were obtained by Mr. Lewis, cannot be mistaken for a variety of G. bifasciata or G. consociata, Baly, on account of the quite different punctuation of the elytra, the interstices of which are impunctate and smooth, the punctures themselves being arranged in single rows. Genus SPHENORAIA, Clark. S P H E N O R A I A I N T E R M E D I A , sp. nov. Black; thorax strongly and remotely punctured; elytra metallic blue, strongly subgeminate punctate-striate, the interstices finely punctured. Length 2 lines. Noheyi. A single specimen. The only two species with which the present one can be compared are S.fulgida and 8. magica, Harold. Both are, however, of double |
