volumes, Blatchley's Coleoptera of Indiana in 2 volumes, and the last two 

 volumes of the Journal and these wrere exhibited to the members for examina- 

 tion. 



Under scientific discussion Dr. Lutz presented an interesting paper on the 

 " Evolution of the Environment," illustrated by several lantern slides. Owing 

 to his absence, due to sickness, this paper was read in part by Mr. Leng. Dr. 

 Lutz discussed the ways in which the land surfaces were altered and lowered 

 by the action of wind, water and other natural agencies, and through the 

 work of man, and then discussed how changes in vegetation occurred follow- 

 ing those in topography, beginning with the mosses and lichens clinging to the 

 bare rocks or those slightly covered with soil and developing to the maximum 

 vegetative condition of the meadow or dense forest. 



Dr. Love gave some " Notes on Insect Collecting in the Yellowstone 

 National Park." He stated that he had taken a pleasure trip to the Yosemite 

 Valley, Cal., the Grand Canyon of the Colorado in Ariz., and the Yellowstone 

 National Park, and had collected insects as opportunity served. Dr. Love 

 described the country, illustrating his talk with a number of beautiful lantern 

 slides, and exhibited two boxes of insects of various orders which he had 

 collected. Dr. Osburn inquired whether insects had been found around the 

 hot springs in Yellowstone Park and stated that the dragonfly, Argia virida, 

 which was southern in its distribution, had been found in the vicinity of the 

 hot springs there and at Banff, Alberta. 



Mr. Davis announced that he had received a letter from Mr. Harris, who 

 was staying at Camden, S. C. Mr. Harris noted that the recent frost had had 

 an injurious effect on vegetation, but that he was finding some interesting- 

 collecting. He had been collecting Cicindela vulgaris Say and repanda Dej., 

 and several specimens of an immaculate form of Cicindela unicolor Dej.

 Wlk., Fairlawn, Bergen Co., April 24, in a meadow ; Euthyatira pudens Gir.,

Mr. Leng stated that he had received from Mr. W. E. Britton, state 

 entomologist of Conn., a copy of a preliminary list of the Coleoptera of 

 Connecticut and would be glad to obtain from the members any interesting 

 records of capture of beetles in Connecticut.
