Show 1888.] COLEOPTERA FROM KOREA. 377 agree very closely with two male examples from the Amur, which I identify with G. viridiopaca var. cupreola of Kraatz described from the same locality. They all differ, in both sexes, from G. viridiopaca, G. bensoni, and G. pilifera very strikingly in the shallow emargination of the thorax adjoining the scutellum. In colour they differ also from those species in being coppery with more or less of an aeneous tinge, more or less subopaque above and brilliant beneath ; the tarsi, and sometimes the tibiae, dark brassy green. An example from Fusan differs from those above described in being dark coppery brown above and densely hairy, the hairs short and erect on the thorax, longer and looser on the elytra. GLYCYPHANA PILIFERA, Motschulsky, Etud. Entom. 1860, p. 15. Fusan. Common throughout Japan. The single Fusan specimen resembles the Yezo form in the dark colour of the four anterior tarsi; in all specimens from the southern islands of Japan which I have examined the tarsi of all the legs are rich coppery like the under surface of the body. GLYCYPHANA JUCUNDA, Faldermann, Mem. Acad. Petrop. ii. p. 386. The numerous examples are in a discoloured condition, and it is not possible to ascertain whether they belong to the North-China type-form or to the Japanese variety (G. jucunda var. argyrosticta). GLYCYPHANA KUPERI, Schaum, Trans. Ent. Soc. (3 ser.) v. p. 69, t. 8. f. 6. Gensan ; two examples. Found also on the Lower Yang-tsze. GLYCYPHANA FULVISTEMMA, Motschulsky, Schrenck's Reise, Ins. p. 135. Gensan. Spread over Eastern Siberia, Northern China (to the Yang-tsze), and Japan. CETONIA SEULENSIS, Kolbe, Archiv f. Naturgesch. 1886, p. 194, t. xi. f. 29. Gensan ; many examples of both sexes. The strong sinuation of the side of the thorax preceding a prominent hind angle, on which Herr Kolbe lays stress, is variable. I find scarcely anything, except the denser sculpture, to distinguish the species from C. brevitarsis, Lewis, and both so closely resemble the Europaeo-Siberian C. marmorata that they can scarcely be considered more than slight geographical varieties of that species. The sides of the clypeus are, as in C. marmorata, scarcely elevated (not carinated as in C. floricola, Hbst., and its subspecies). The pygidium is extremely closely rugulose and not convex in either sex ; the abdomen is longitudinally concave in the male. CETONIA SUBMARMOREA, Burm. Handb. d. Ent. iii. p. 460. Gensan ; two examples. Common in Japan. |
