PREFACE. 



The following Catalogue has been undertaken, not solely with 

 the view of recording some additions to the Insect Fauna of 

 Scotland, but also with the intention of correcting the synonymy 

 of some of the species which have been established on the 

 authority of our great British Entomological authors, where 

 subsequent investigations have shown that species have been 

 improperly multiplied, or new names given to species already 

 described. I have also wished to do something towards making 

 our British Entomologists more familiar than they are with 

 the names generally in use on the Continent. For these reasons 

 I have made the following list a Synonymic Catalogue. 



I have adopted the arrangement of Redtenbacher, and I have 

 done so notwithstanding some doubts of my own as to its 

 superiority over Latreille's, partly in deference to the opinion 

 which appears to be now generally entertained that it is the 

 most natural, and partly because it comes nearest to that first 

 developed and adopted by our own Stephens, and which is con- 

 sequently already most in use in this country. 



As regards the synonymy of Continental authors, I have 

 followed Gaubil's catalog-ue, unless in one or two instances where 

 I had reason to suppose he was in error. As to the synonymy 

 of species described by Mr Stephens, I have had the very 

 great advantage of the free use of my friend Mr Little's
