^ On page viii of his "Nature Studies in Temperate North Amer- 

 ica" Hancock makes the statement that "when not otherwise stated, 

 these word sketches have been drawn from my diary notes, covering 

 many years, made at Lakeside, Berrien County, Michigan." Also, 

 on pages 325 and 329 there are illustrations of Orthopteran habitats 

 made from photographs taken at Lakeside, with lists of the species 

 found in them. However, in his notes on the habits and habitat of 

 the species of Orthoptera treated there is in most cases no indication, 

 of the locality where the observations were made, so that without 

 careful perusal of the book these records may easily be overlooked, 

 as apparently has been generally the case. Since these Lakeside rec- 

 ords are not in such form as to be easily available, in the accompany- 

 ing list note is made of the fact whenever a species has been recorded 

 by him from that locality. 



All determinations of specimens here recorded are by the author 

 unless otherwise noted.
