Belladonna_. Fabricius, as it appears from his references in his Entomologia Systematica, met with the drawings of this species in the collection of Mr. Jones, whose cabinet also possessed the original specimen from which the drawing was taken. It is from this individual example in the cabinet of Mr. Jones that the delineation in the annexed plate is copied.
