PREFACE. 



1 HE object of this book is to present a Catalogue of the 

 well-established species of Longicorn Coleoptera, with 

 references to where they are figured and to the more 

 important synonyma, with descriptions of some species 

 which appear to be as yet unnoticed in Entomological 

 works. 



It is intended for the following purposes : — 



1 . As a list of the species contained in the Museum Col- 

 lection. They are marked B.M. in the outer margin. 



2. To point out the Desiderata of that Collection at the 

 period of publication. 



3. As labels for the Cabinet. 



The species marked Chevr. Coll. have been compared 

 with the corresponding species in the extensive collection 

 of M. Chevrolat of Paris, which include the type specimens 

 named in the Baron Dejean's Catalogue. 



The remaining Parts are in progress, and will follow as 

 soon as they can be completed.
