among the most radical changes, brought about by man, as 

 the change is from an aquatic to terrestrial flora and fauna, 

 yet others scarcely less fatal to insect life, are everywhere 

 going on, and while species are, perhaps, not wholly and 

 totally exterminated like the buffalo, like the Indian, only 

 such as can adapt themselves to the change may yet lead 

 an unnatural life in the few areas where the hand of civil- 

 zation has fallen less relentlessly, much as Reindeer-moss, 

 Cladonia rangifcn'na, has been found by our fellow member 

 to retain its hold, in a single instance, near Cleveland. Some 

 years ago Mr. Bolter, an old collector of Chicago, wrote 

 me that the white Tiger Beetle, Cicindclu lepida, though 

 formerly common, had become nearly or quite extinct. 

 Recently while riding about Buffalo, N. Y., with an old collec- 

 tor, he pointed out to me what had been at one time one of his 

 best col lecting grounds. In fancy I could depict a sunny 

 bank, in a wood not too dense but with openings, and a 

 small stream flowing cl ose under the bank, leaving a low 

 grassy plat along the opposite side; but now the trees were 

 gone, except one or two, scraggy, blackened with the smoke 

 and grime of the city, the grass cropped close to the ground, 

 and the stream half filled with ashes and rubbish. Some 

 years ago a friend of mine proposed to take me to an old 

 hunting ground of his, where for many years, as he told me, 

 he had seldom gone without getting something good. It 

 was May, and he had been prevented from visiting his fa- 

 vorite haunt since the previous fall. As we walked along, 

 after having gone some distance, he suddenly stopped, and 

 with an explanation of pain, surprise and disgust, pointed to 

 a small field from which the trees and shrubs had evidently 

 been but recently removed, and enclosed with a new fence. 

 Within this enclosure a flock of sheep were quietly grazing. 

 It very frequently occurs that the first cultivated crop planted 

 upon recently reclaimed swamp lands, is ruined by the dep- 

 redations of the former insect inhabitants, Sfhcnofhorus
