THE CANADIAN ENTOMOLOGIST, 187 



lished the results of his labors and his mode of operating in our journal. 

 His success was so unprecedented, and so many rare or hitherto unknown 

 species captured, that collectors everywhere were induced to imitate his 

 example, and in the short time that has since elapsed an immense number 

 has been added to the list of known species, and our collections have 

 been enriched by this means with an extensive series of hitherto rare 

 specimens. 



Our monthly journal, the Canadian Entomologist, is still well sus- 

 tained, its pages being regularly filled with interesting and original con- 

 tributions. Did time permit, I might have occupied your attention at 

 considerable length by referring to the many valuable points brought out 

 in these papers. I cannot, however, refrain from adverting to the con- 

 tributions of Mr. W. H. Edwards, of West Virginia, on the life history 

 of some of our butterflies, in which it has been shown that not a few of 

 our so-called species are merely dimorphic forms of other species, and 

 attention drawn to the important influence of cold in modifying these 

 forms. By exposing the chrysalids to the influence of this agency by laying 

 them for varying periods on ice, or placing them in an ice house, some 

 of these dimorphic forms have been produced at will, thus throwing much 

 light on the causes of variation in species. 



I would also call your attention to the many recent valuable additions 

 to Entomological literature in America, especially to the beautifully illus- 

 trated work of Dr. A. S. Packard on the Geometrids of North America ; 

 to the continuation of Edwards' magnificent work on North American 

 Butterflies ; to the learned and elaborate treatise on the Ryncophora of 

 America north of Mexico, by Drs. LeConte and Horn ; to the excellent 

 works of Prof Townend Glover, of Washington, on American Diptera, 

 Orthoptera and Hemiptera ; to the valuable reports of the State Ento- 

 mologist of Missouri, and many other excellent works. But I must not 

 trespass longer on your patience. Thanking you for your kind partiality 

 in honoring me as you have done, I have the honor to be 



Yours very sincerely, 



Wm. Saunders.
