Society of Philadelphia in 1864, he attacked Agassiz and Dana in 

 opposition to their views. The same year, in the same Proceedings, 

 he published a very suggestive paper entitled " On Phytophagic Vari- 

 eties and Phytophagic Species." 



The very first article in the just-founded Practical Entomologist 

 is one of great historic interest. It is entitled '' The New Potato Bug 

 and Its Natural History," and, as stated above, from that time on 

 until its finale the Practical Entomologist contained article after arti- 

 cle that may be read to great advantage today. 



In the Proceedings of the Philadelphia Entomological Society in 

 1865 was published an important paper entitled " On Phytophagic 

 Varieties and Phytophagic Species, with Remarks on the Unity of 

 Coloration in Insects," in which he argued for the origin of races 

 and species by phytophagic isolation. In 1866, in the Practical Ento- 

 mologist of September 29, he listed European insects imported into 

 America and American insects imported into Europe, and discussed 

 the reasons for the increase in abundance of noxious European 

 insects in America, giving his reasons why American species do not 

 flourish in Europe. His last papers of importance were concerned 

 with Hymenoptera, and were broad and sound and important. 



His report as Acting Entomologist of Illinois published. in the 

 Transactions of the Illinois State Horticultural Society for 1867 is 

 lengthy, covering 103 pages and containing 14 chapters upon differ- 

 ent insects of importance. We do not do things nowadays the way 

 he did, but it would be better for some of us if we would study this 

 particular report. Few people can write the way Walsh wrote, and 

 he had a way of stressing important points that was masterly. 



Charles Valentine Riley 



Professor Riley was born at Chelsea, London, September 18, 

 1843, 'iii'^l fl'cd 3t Washington, September ig, 1895. As a boy he 

 went to school at Bayswater and Chelsea in England, and to board- 

 ing school in Dieppe in France, and for a year at Bonn in Ger- 

 many. He was a lover of nature ; collected insects from an early 

 age, and had a passion for sketching them. His cleverness with his 

 pencil was so great that one of his teachers urged him to become 

 an artist. 



A sudden crisis in the finances of his family induced him, as a 

 boy of 17, to come to the United States. He went to Illinois and 

 was employed on the farm of Mr. George H. Edwards, about 50 

 miles from Chicago. He was much interested in the insects on the 

 farm, nearly all of which were new to him, and he watched their
