By John. B. Smith, Sc.D. 
In 1890 I published a revision of the species theretofore lumped under 
the generic term Agrotis, as Bulletin No. 44 of the U. S. National Mu¬ 
seum, and divided up the species among fifteen genera, new and old.. 
The general conclusions reached in that paper have approved themselves- 
to me since that period; but the increased material has necessitated 
some changes in the standing of certain species. 
The genus Noctua as restricted by me contained species with all the 
tibiae spinose, the anterior not heavily armed ; front smooth and feebly
