This insect is placed by Mr. Ragonot in his Catalogue N. A. Pliy- 

 citidoe as a synonym of Earythmia hospitella Zell. It very much 

 resembles some specimens of that species in general appearance, and 

 I may have inadvertently made a mistake in determining what I 

 sent Mr. Ragonot. The type in my possession is a Myelois.
