COLEOPTERA FOR EXCHANGE. 



The undersigned desires Coleoptera from all parts of North America ; 

 will give in exchange named Coleoptera, unnamed insects of other orders, 

 shells or plants. Small collections of named Coleoptera, illustrating the 

 principal families, for sale on reasonable terms. Lists of duplicates fur- 

 nished on application. Information concerning the habits or distribution 

 of species, especially from New England and adjacent regions, will be 

 very acceptable. 



The attention of collectors is particularly called to the White Mountain 

 region hi New Hampshire, as affording the best field for the discovery of 

 new and interesting forms in all orders. A partial list of the Coleoptera 

 of that region, with descriptions of new species by Dr. LeConte, was pub- 

 lished by me in the Proceedings of the Boston Society of Natural History 

 Vol. xvi, 1874, which will show what may be done by a few days collecting ' 

 in that region. (Copies may be had at the Naturalists' Agency, Salem.) 



Many additional species have since been taken by the members of a 

 collecting party last summer and it is proposed to publish, at some future 

 time, a complete list of all insects found in that region, and the coope- 

 ration of all collectors is invited, in order to make the list as complete as 

 possible.
