 show a discal ovate hlackish spot ahout the cross vein, and a very faint 

 tracing of a subterminal band.

Ufeus plicatiiSj Grote. 



S . — Smaller than U. satyricus. Body of the same flattened shape and 

 color but the fore wings show a uniform, warm, faintly reddish tinge. T. 

 a. line broken. Along the cell, above the median vein, is an interrupted black 

 streak. Transverse posterior line black, comparatively very distinct, running 

 outwardly and downwardly obliquely from costa, much and roundedly exerted 

 opposite the cell and offering a distinguishing character by its course as com- 

 pared with that of U . satyricus. It appears interspaceally lunulate from a 

 short extension of the black scales upon the veins beyond the line. A series of 

 fainter blackish interspaceal terminal streaks. All the markings are deter- 

 minate, not reflected. Hind wings dull testaceous above, and, with thg upper 

 wings, beneath, absolutely without marks or lines of any kind.

I cannot regard these as sexes of the same species owing to the 

 difference in the course and appearance of the transverse posterior 

 line. These two species cannot be referred to Mythimna, which is 

 restricted by Lederer to the European M. imbecilla. Apparently 

 Mr. Walker's extension of the term to include Guenee's Leucania 

 pseudargyria, etc., should not be followed.
