PREFACE. 



In presenting to the public the present catalogue of the insects 

 hitherto found inNorway, I wish to make a few short preliminary 

 remarks. 



While the fauna of our country has in many directions, espe- 

 cially as regards the vertebrated animals and the lower forms of 

 animal life, found a great number of eminent students, and has 

 been accurately examined, as well by Norwegian as by French authors, 

 and in various works introduced to public notice — entomology has 

 had very few votaries in this country; and there is not at present 

 before^ the public any work which can shew what Norway possesses 

 in this branch. What may have been recorded in journals of older 

 times as to the occurrence of insects in certain parts of our country, 

 is so little and so incomplete that no conclusion can with certainty 

 be drawn from it. 



Having now for a series of about 30 years employed my leisure 

 time in studying entomology, and constantly collected insects, partly 

 for my own store, which at present comprises about 5000 species 

 and about 24,000 specimens, partly for the University, on my jour- 

 neys undertaken with the assistance of Government, in the various 

 regions of the country, I think it expedient, in the interest of the 

 science, to lay before the public a catalogue of the insects found 

 in this country, chiefly based on what I myself have collected, and 

 also on what has been ah'eady noticed by other collectors in various 

 works, and on the researches I have had occasion to make with 

 respect to the collections of others. 



I must however state that I myself have hitherto only had 



occasion to examine the southern or central part of our country;
