tural points, whilst descriptions of all the known genera 

 of Beetles are being published in Lacordaire's ' Genera 

 des Coleopteres' (in the 'Nouvelles Suites a Buffon'), 

 Paris, of which four volumes have been published as yet. 



The standard works on the Coleoptera of the northern 

 parts of the Continent must be consulted for descriptions 

 both of the species recorded as British, and of those 

 likely to occur here ; this course requires a knowledge 

 of French, Latin, and German, but is, unfortunately, 

 indispensable. The following are most useful : 

 f Insecta Suecica : Coleoptera sive Eleuterata/ by L. 



Gyllenhal, 1808-27, 4 vols. (Latin.) 

 ' Die Kafer der Mark Brandenburg/ by W. F. Erichson : 



Berlin, 1837, 1 vol. (Latin and German.) This work 



was never completed. 

 ' Naturgeschichte derlnsectenDeutschlands: Coleoptera/ 



by Dr. Erichson, Dr. Schaum, Dr. Kraatz, and H. von 



Kiesenwetter : Berlin. Still in progress. (Latin and 



German.) 

 ' Skandinaviens Coleoptera/ by C. G. Thomson : Lund, 



1859. Still in progress; 6 vols. published. (Latin 



and Swedish.) 

 ' Fauna Austriaca : Die Kafer/ by L. E/edtenbacher : 



Vienna, 1858, 1 vol., 2 plates. (German.) 

 1 Faune Entomologique Fra^aise : Coleopteres/ by 



MM. Fairmaire and Laboulbene : Paris, 1854. Not

(N.B. Most foreign publications can be obtained of 

 Messrs. Williams and Norgate, Henrietta Street, Covent 

 Garden.) 



Many descriptions occur also in the Berliner and 

 Stettiner Entomologische Zeitschriften; the 'Annales' 

 of the French, and Transactions of the English, Ento- 

 mological Societies.
