THE AMERICAN ENTOMOLOGICAL SOCIETY 



announces the inauguration of a new series of entomological papers 

 of monographic character, to appear as frequently as suitable 

 manuscripts and sufficient funds are available, and to be called the 

 Memoirs of the American Entomological Society. The Memoirs 

 are to be of a large octavo size, and each paper will form a separate 

 number complete in itself. As the individual numbers will proba- 

 bly vary greatly in the number of pages, above a minimum required 

 for the series, no fixed price per number will be made, but the 

 charge will be computed for each unit upon a pagination basis. 



The first number of the Memoirs will be issued during the month 

 of June, and will appropriately contain "The Cresson Types of 

 Hymenoptera," by Ezra Townsend Cresson. This contribution 

 will prove of the greatest value to the taxonomic Hymenopterist 

 working on American forms, as it is a full catalogue of the 2737 

 species described by the author, with original references, selection 

 of single types, location and number and condition of the same, to 

 which is appended a bibliography of the entomological papers of 

 the author. Further information regarding the paper, its pagina- 

 tion and price will be furnished on application. 



AMERICAN ENTOMOLOGICAL SOCIETY, Logan Square, Phila'da, Pa. 



N. B. In reply to recent inquiries, the Society can no longer furnish copies of LeConte and 

 Horn's Classification of the Coleoptera of North America, or Henshaw's List of the 

 Coleoptera of America North of Mexico, both of which are out of print.
