Delicate ocher-vtdlow, with a reddish tinge toward the edge of the 

 wings, and on the head and front of the thorax. Fori' wings with two lines, 

 often internipted, or only developed on the costa ; inner line on tin; inner 

 third of the wing; the cnrvcd onter line, beginning near the inner, diverges 

 and follows a sinuate course, ending much nearer the ajjex than the inner 

 line, the distance varying; botli wings speckled, sometimes thickly, with 

 utuisnally large spots; outer edge of both wings deeply excavated, especially 

 opposite the second median venule. On the iiind wings, no lines; an obscure 

 discal dot centered with a short translucent line. Beneath, much as above, 

 but no lines, except in one case a diifuse dark line crosses the hind wings. 

 (The female ditFers in the usual characters of the dentated forms.) Fringe 

 dark, whitish in the notches on both wings. 



Length of l)o(ly, ^, 0.80, 9, 0.65; of fore wing, <} , O.flO-l.OS, 9, 0.9")-

The species varies considerably in the distance apart of the two lines 

 on the tore wings, and in the degree of spotting. Our si)ecimens do not 

 apparently differ from Knropean one.s.
