BROOKLYN. OCT. 1878. 



To the Coleopterists and Lepidopterists of ths United 



State*. 



The principal aims of the Bulletin are : 



1. To give Synoptic Tables of the N. A. Coleoptera and Lepi- 

 doptera. 



The desfriptions of the N. A. species have been published in 

 widely scattered papers in England, Germany, France, Russia, 

 Holland, Belgium, Sweden, Italy, etc. It is almost impossible 

 to obtain all these descriptions, or even those that have appeared 

 during the last twenty-five years in this country. It would ap- 

 pear, therefore, to be a valuable and meritorious work to give 

 these Synoptic tables, ] articularly as in very many instances the 

 size and locality of a species will enable a collector to determine 

 it. 



2. To pay special attention to the early stages of our Coleop- 

 terous and Lepidopterous species. 



The student of this part of entomology will find it more re- 

 munerative and interesting than any other, and our Bulletin has 

 shown in several instances that the Lepidopterists are further ad- 

 vanced than the Coleopterists in this direction. 



3. To present a medium wherein collectors can exchange their 

 experiences, and to afford opportunities for the exchange of dup- 

 licate specimens. Many collectors have a greater or less number 

 of fine duplicates, which they might exchange for desirable rare 

 species by offering them in our paper at a cost of 25 cents. 



The price of the Bulletin is so low (60 cents for 12 monthly 

 numbers), that every collector of Coleoptera and Lepidoptera can 

 afford to subscribe for it in view of its many advantages, and 

 particularly of its Synoptic tables, which begin in No. 1.
