1888.] COLEOPTERA FROM KOREA. 373 



Apogonia cupreoviridis, Kolbe, Archiv f, Naturgesch. 1866, 

 p. 193. 



Gensan ; four examples. 



The species (if I have determined it aright) differs from A.splen- 

 dida (Boh.) of Japan and China in the more arcuated outHne of the 

 clypeus, which describes the segment of a circle, not flattened as in 

 A. splendida, and in the sides of the eh'tra at their widest part 

 having only two instead of four smooth interstices. 



LaCHNOSTERNA DIOMPHALIA. 



L. parallelse {Motsch.) affinis et simillima, sed divert pyyidio S 

 valde convexo, ante apicem bicalloso. Long. 20 millim. 



Fusan ; two examples, S ■ 



Similar to the common Japanese and Chinese L. parallela 

 (Motsch.) ; of similar elongate oblong form, shining black colour, and 

 strong but separated punctuation of the head and thorax. The 

 males, however, differ greatly : in L. parallela the pygidium is 

 simply and moderately convex, and the apical ventral segment 

 transversely convex ; in L. diomphalia the pygidiuin is bigibbous a 

 little before the apex, with a strong marginal groove, and the apical 

 ventral segment is large and transversely tumid. 



Lachnosterna morosa, Waterhouse, Trans. Ent. Soc. 18"5, 

 p. 104. 



Three examples, one black and two piceo-castaneous. 



Lachnosterna ? 



A single example ; undeterminable. 



Hoplosternus japonicus, Harold, Abhandl. nat. Ver. Bremen, 

 iv. 1875, p. 291. 



One example only, a 5 , having a longer sternal spine than 

 Japanese specimens ; but as the latter vary considerably in the length 

 of the spine, it is open to doubt whether the Korean insect is speci- 

 fically distinct. 



Fam. RuTELiD^. 



Phyllopertha conspurcata, Harold, Deutsch. ent. Zeitschr. 



1878, p. 71. 



Taken abundantly at Gensan. Also found in Japan. 



Anomala rtjfocuprea, Motschulsky, Etud. Entom. 1860, p. 14; 

 Harold, Deutsch. ent. Zeitsch. 1877, p. 350. 



All the very numerous examples taken by Mr. Leech differ from 

 Japanese specimens in the rather stronger and closer punctuation of 

 the upper surface of the body, the punctures on the elytra tending 

 to coalesce into transverse rugse. The wide range of colour-vari- 

 ation is similar in both forms, viz. — 1 (typical and the least 

 numerous), coppery red ; 2, brassy-green in different shades ; 3,
