87Since Dr. Warren in his later works has also 
accepted Michener’s hypothetical species, it is in- 
teresting to observe how easily an evident error can 
be perpetuated. In the instance of M.g.grieseus 
Dowitcher, in which he gave Michener (1881) as 
his authority for its occurrence in Chester county 
(Bds. Pa., 235), and a year or so later, no doubt 
with the above in mind; stated that specimens had 
been taken (Ibid. 2nd ed., 83), and in 1892, Stone 
gives Warren’s later statement as his authority for a 
Chester county record (Bds. E. Pa. and N. J., 72).
