The article, taken from advance sheets from the fourth report U. S. Entomological Commis- 

 sion, discusses the question of the nomenclature of the Noctuid, popularly known as the Cot- 

 t on- worm moth. From a study of Iluebner's figures and description, and an inspection of the 

 Soinmer collection in Dresden, the conclusion is reached that Huebner's specific name, argillacea, 

 must bo rejected aud Say's name, xylina, retained.
