The primary object in composing this catalogue was to facilitate 

 the exchange of Coleoptera between the collectors of both continents 

 who desired to obtain as many as possible of the species common to 

 both. It was then seen that the addition of the distribution of these 

 species in this country so far as known, and also a general view of 

 the European and Asiatic distribution, would be of gi'eat use, and 

 valuable in other directions. Catalogues with the general distribu- 

 tion of the species in Europe and Asia are available by the American 

 student or collector, but no work of this kind has been attempted in 

 America, and the distribution with us of the species common to both 

 countries is mostly unknown in Europe, and known even here to 

 comparatively few. 



The information relating to the American distribution has been 

 gleaned from the works of our systematic authoi-s, and the various 

 catalogues of collectors as will be seen by the bibliographical refer- 

 ences ; while my own collection, and specimens obtained from many 

 places, have enabled me to give much local distribution not hereto- 

 fore on record. The cabinets of many collectors would, no doubt, 

 add much knowledge in this direction were their contents known. 

 The want of local catalogues at several points was greatly felt in 

 prosecuting this work, notably Nova Scotia, Massachusetts, District 

 of Columbia, Louisiana, Manitoba, British Columbia. The Kansas 

 catalogue is too disjointed to be easily consulted. 



Where Alaska, Sitkha, Kenai, Unalaschka, Kadjak are men- 

 tioned without reference, in nearly every instance Mannerheim's 

 contributions to a knowledge of the Coleoptera of the Pacific coast 

 are the authority. The first of these was published in the Bulletin 

 of the Imperial Society of Naturalists of Moscow in 1843, and sup- 

 plements in 1846, 1852 and 185o respectively, the whole constituting 

 a catalogue in which all the species taken in Alaska till the date
