The object of this notice is to call the attention of American Entomologists to a most excellent and complete “Revision of the Family Sphingidæ,” by Arthur G. Butler, of the British Museum, which has appeared in the Transactions of the Zoological Society, London, in quarto form. A proper arranqement of the Sphingidæ of the world is a work requiring both extensive material and great experience and tact, of which Mr. Butler has shown himself to be equally possessed.
