PEEFACE. 23 



concluding portion of the seven years in which I 

 held the position of Director of the Museum in the 

 Buffalo Society of Natural Sciences, has made 

 several beavitiful drawings for me, and was a kind 

 and intelligent aid in my entomological work. I 

 cannot forget my departed friend Hochstein, un- 

 rivalled as a painter of butterflies and moths. 



In this brief resume of the sources from which I 

 have drawn information, I have no doubt omitted 

 to mention the names of several entomologists who 

 have corresponded with me. As I write I recall 

 Mr. James Angus, who sent me some fine Cato- 

 calas from his captures at West Farms, N.Y., and 

 Mr. Dury, who has collected many species at Cin- 

 cinnati. There is no more pleasant task than that 

 of recalling all the friends one makes in connection 

 with a pursuit like Entomology; but with my 

 acknowledgments to Mr. George Norman, of Cluny 

 Hill, who spent some time in Canada successfully 

 collecting Noctuida3, my list must end. Besides 

 discovering Lithojjhane Georgil, two pretty species, 

 Agrotis Normaniana and d'ocigrapha Wormam, 

 were among Mr. Norman's captures, and will serve 

 to remind him of American Entomology.
