GORHAM ON THE [Mar. 17, tisque quinque, duabus basalibus, duabus discoidahbus et una longiori submarginali pone medium, nigris; antennis ™9™>J" cutis secundo ad quintum testaceis; capite, corpore et pedibus nigris fortiter sat crebre punctatis; abdominis latenbus hand distincte testaceis. Long. 7 millim. 3 2 • Hab. Japan (G. Lewis). , , This new C W / a is not very nearly allied to any yet recorded from Japan or Siberia. It may easily be recognized by the elytra with one long smooth costa near the suture, which, commencing at the base, nearly reaches the apex; two other raised interstices, forming costules, start, one from inside, the other from the summit of the humeral callus; but these are shortened and confused with the rugose sculpture sooner than the sutural one. The thorax is longer proportionally than that of C. equestris, to which, in having its hind angles rounded, it may be compared; but these angles are more suddenly cut off, as it were truncated, and the whole surface is very much more coarsely punctured. In one of the two examples, in which the thorax is quite as wide as the elytra, there are two pale spots, which Mr. Lewis observed in life to be of a fine green-yellow ; this, I think, from its form and from the sixth segment of the abdomen being distinct, to be the male. The suture is a little raised and there is a deep sutural stria, between which and the first costa there is an obsolete interstice and stria. The two basal black marks are small spots, the external one elongate; the two discoidal ones are elongate dashes in line, but not united; the submarginal one is as long as these would be if united, and curved towards the apex. Legs very distinctly punctured. Two specimens ; found in Central Japan. CASSIDA NEBULOSA. Cassida nebulosa, Linn.; Boheman; Baly, loc. cit. p. 213 ; Kraatz, loc. cit. p. 270. Japan; Kawatchi (G. Lewis). Apparently rare in Japan. Mr. Lewis only met with one example in 1881 at Wadatoge. CASSIDA FUSCO-RUFA. Cassida fusco-rufa, Mots. Bull. Mosc. 1866, i. p. 178; Kraatz, loc. cit. p. 268. Cassida consociata, Baly, loc. cit. p, 213. Japan, Central and South Japan (G. Lewis). CASSIDA VESPERTINA. Cassida vespertina, Bohem. Cass. Suppl. p. 357; Baly, loc. cit. p. 213. Japan (G. Lewis). Very rugose; thorax marked with black at the angles and on the disk, very little shining; elytra rising to a point, with diverging |
