To the great kindness of Prof. French I owe a copy of the Bulletin of the U. S. National Museum No 38, which contains Prof. Smith's Revision of the North American Species of Agrotis. In view of the fact that out of the 252 species reviewed by Prof. Smith, no less than 110 are credited to myself, besides five species “not placed,” it might be reasonably supposed that I was interested to receive this publication and that I must regret not having received it before publishing my New Check List.
