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 scutelhun. 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 tlie 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, Mom. 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 sexjlensis, 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 Europseo-Siberian C. mar- 

 morata that they can scarcely be considered more than slight geo- 

 graphical varieties of that species. The sides of the clypens are, 

 as in C. marmorata, scarcely elevated (not carinated as in C.Jloricola, 

 Hbst., and its subspecies). The pygidium is extremely closely rugu- 

 lose 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.
