Vlll PRELIMINARY OBSERVATIONS. 



authenticated examples exist in any collection, which may as 

 well be here disposed of. 



Lebia ephippium, Steph. Manual, App. p. 433. Doubtless 

 imported. 



Carabus agrestis, Creutz., et Lippii, Dahl. Said to have been 

 found in Lincolnshire. 



Nebria picicornis, Fab. Stated to have been captured by the 

 Rev. F. W. Hope in Longmont Forest. Its natural habitat is on 

 the muddy banks of rivers and lakes, and the locality in which it 

 is reputed to have been found is so widely different from those 

 which it naturally affects, that I am inclined to suspect it has been 

 introduced into the British Fauna by mistake. 



Helobia impressa, Newm. I have not seen this insect ; it pro- 

 bably belongs to Nebria nivalis. 



Licinus cassideus, Fab. Not indigenous ; a specimen is reputed 

 to have been found at Aldborough. 



Epomis circumscriptus, Dufts. Not British ; it is represented 

 in the Stephensian cabinet by two Chlcenii from the Cape, as stated 

 by Dr. Schaum in the ' Stettin Transactions.' 

 Sogines punctulatus, 111. 

 Cophosus elongatus, Sam. 

 Pterostichus fasciopunctatus, Fab. 



Panzeri, Meg. 



Cheporus metallicus, Fab. 

 Agonum Bogemanni, Gyll. 

 Amara municipalis, Dufts. 

 Zabrus obesus, Latr. 

 Pangus Scaritides, Sturm. 

 Peryphus Fellmanni, Gyll. 

 Lopha nana, Steph. 



No example exists in any British Collection to represent the 

 above species. 



Although the present work has been undertaken merely with 

 the view of furnishing a descriptive arrangement of the species of 

 Geodephagous insects indigenous to the British Isles, yet it will 

 be proper to offer some remarks on the Generic arrangement 

 which I have employed, inasmuch as it differs from that which 

 is ordinarily received by English entomologists. 



It is evident that the principle upon which the Brachinida, 

 Scaritida, Harpalidte, and Bembididte have been erected into 

 distinct families, and placed upon a footing of equal importance
