This seems to show that the source and perhaps the epoch of immi- 

 gration of tropical forms have heen different for the two countries. 

 It is, however, too soon to generalize with confidence on these points, 

 seeing that we at present know scarcely a tenth of the species of 

 Coleoptera almost certainly existing in Korea. I put forward these 

 considerations, suggested by the examination of a large portion of 

 Mr. Leech's acquisitions, chiefly to show that interesting problems 

 lie before us in the fauna of this country, and that an attractive 

 field lies open for future travellers and residents. 



Fam. CiCINDELIDvE. 



CiciNDELA CHiNENsis, De Geer, Ins, 4, t. 17. f. 23. 



Two examples, closely resembling the richly-coloured form pre- 

 valent in Japan. 



CiciNDELA GEMMATA, Faldermann, Mem. Acad. Petrop. ii. 

 (1835), p. 14, t. 3. f. 1 ; Kolbe, Archiv f. Naturgesch. Berlin, 

 1886, p. 164, t. xi. f. 21. 



Taken abundantly at Gensan, and found also by Dr. Gottsche 

 between Soul and Fusan. On the Amur it reoccurs as a rather 

 well-marked variety. Faldermann described it from Mongolian 

 specimens taken by Bung more than half a century ago. To Herr 

 Kolbe belongs the credit of resuscitating this species, which had been 

 by most authors suppressed as a synonym of C, sylvatica, from which 

 it is very distinct. 



CiciNDELA RADDEi, Morawitz, Bull. Acad. Petrop. iv. p. 188 



(1862). 



Three examples, agreeing well with the above-cited description. 



CiciNDELA jAPANENsis, Chaudoir, Bull. Mosc. 1863, i. p. 202. 

 Many examples taken at Gensan. Common in Japan and on 

 the Asiatic mainland as far south as the Yang-tsze. 



Fam. Carabid^. 



Carabus van-volxemi, Putzeys, Ann. Soc. Ent. Belg. xviii. 

 p. 2. 



Gensan. One example only, differing from Japanese specimens 

 in the fainter granulations of the interstices, and possibly indicating 

 a distinct local variety. 



Carabus tuberculosus, Dejean, Sp. Geu. Col. v. p. 549. 

 Gensan, one example. 



Carabus bilbergi, Mannerheim, Hummel's Ess. vi. p. 25. 

 One example, apparently an elongate variety of this species. 



Coptolabrus smaragdinus, Fischer, Ent. Buss. ii. p. 103. 

 Two examples of a rich uniform golden-coppery colour, the apex
