Excluded Species. 



GROUP I. 



The following species were reported from Berkshire County by 

 Dewey in the list published in 1829 (see Introduction, page 178), 

 but they have not since been found in the County. In many cases, 

 Dewey has included species whose range excludes the probability of 

 their occurrence in the County. Occasionally the species listed by 

 him probably represents a species known to occur in the County and 

 not given by him. In a few cases, marked below by an asterisk, it is 

 probable that Dewey actually found the species listed and that it has 

 not been collected since. 



The names are those given by Dewey. If they differ from those of 

 the seventh edition of Gray's Manual, the latter are given after the 

 original names. Where a locality is given, it is quoted from Dewey's 

 list.
