the collection of Dr. Pflug, from America ; I give 

 it as an Hydrobius. I can add no information of 

 what became of the above collection. 



Sp. 13. Bicoloi\ — Now a Philhydrus of Solier. 

 For the characters of the genus refer to the Hist, 

 Nat. des Insectes par Audouin et Brulle, vid. vol. 2. 

 p. 276. 



Sp. 17. Erythrocephalus. — Described originally 

 from Lund's Cabinet ; no locality is given, although 

 it is most likely to be an European species of the 

 genus Hydrobius. Erichson thinks it is only a 

 dark variety of Hydrobius griseus, vide p, 211. 

 Die K'afer der Mark Brandenburg. 



Sp. 18. Hcemorrhoidalis. — Now a Cercyon of 

 Dr. Leach. Mr. Stephens has described in his Illus- 

 trations of British Entomology sixty-one species ; 

 the Baron De Jean mentions in his last Catalogue 

 but twenty, including exotics of the Old and New 

 World. This may be taken as an example that the 

 Entomologists of England are not behind their 

 Continental neighbours in research or assiduity. 



Sp. 27. Minutus. — Now an Hydrobius, and pro- 

 bably only a variety of Hyd. bipunctatus. 



Sp. 30. Truncatellus. — Now a Limnebius of 

 Leach. Apparently the Chrysomela minuta Linn, 

 described in the Fauna Suecica, is a Limnebius.
