58 JOHN B. SMITH. 



riation is in the same direction as in perexcellens, the two specimens 

 before me showing strong differences, while evidently referring to the 

 same species. 



Since the above was written I have seen a series in the United 

 States National Museum which runs from the form above described 

 to a uniform black the maculation scarcely identifiable. The series 

 is bred, so there is no question as to the identity of the specimens. 



Since the mss. of the above descriptions was handed in, I have 

 deposited a series of types in the collection U. S. National Museum, 

 which contains nearly all of the species above described. The col- 

 lection now contains more than seventy-five per cent, of all the de- 

 scribed species of Agrotis, and in generally finer series than any 

 individual collection known to me.
