AMERICAN LEPIDOPTERA. 71 



curved below the cell. S. t. space more or less brown and violet shaded and 

 mottled. S. t. line obscure, broken, yellowish, irregular, preceded by black 

 scales. Terminal space largely bluish or violet, except at apex where it is ocber- 

 ous brown. A row of black terminal lunules. The fringes are usually mottled 

 with brown, gray and violet, and may or may not be cut with a whitish or yel- 

 lowish shading at one-third from apex and at the same distance from hind angle. 

 Orbicular an incomplete black ring. Reniform round, of good size, black ringed, 

 metallic blue filled, centered by black. Secondaries soiled whitish or smoky, a 

 little darker along the outer margin. Beneath, primaries tawny, varying in 

 depth, the raaculation of upper side obscurely indicated ; secondaries whitish, 

 with an obscure dusky lunule, and a dusky costal patch one-third from apex. 

 Expands 24-30 mm. =^ .96-1.20 inches.

Eight examples, representing both sexes. This species is well de- 

 fined and varies little in the series from widely separated localities 

 before me. The basal region has usually a yellowish or ocherous 

 tinge; but the costal, ante-apical spot is always white. The round, 

 large, blue filled reniform is further characteristic. The primaries 

 are a little narrower at base and therefore more triangular than in 

 aprica. Secondaries with vein 5 nearly as strong as the others, 

 variable in point of origin. It may come directly out of the median 

 at the end of the cell, or it may be on a short spur from the trans- 

 verse vein, no two specimens being exactly alike in this matter. 

 Veins 3 and 4 branch only a little beyond the end of the cell.

 Head brown ; thorax and abdomen creamy white. Primaries creamy white 

 from base to apex along costa and from base to median shade along the inner 

 margin. Basal line more or less clearly marked as a dull smoky spot on costa. 

 T. a. line smoky, single, outwardly oblique to the median vein, then nearly ver- 

 tical and narrowed to the hind margin. Median shade starting as a luteousmark 

 on costa, lost in the cell, but reappearing below it as a broad luteous brown baud 

 that reaches the t. p. line and forms the inner portion of the dark marking of 

 the wing. T. p. line luteous on the costa, broken below it, forming a black curve 

 well beyond reniform, then deeply incurved, black, more or less broken, some- 

 times a little diffuse, always rather prominent. The s. t. space is brown to the 

 costal region, more or less black marked before the s. t. line, often with a violet 

 shading. Terminal space pale luteous. S. t. line of the pale ground, irregularly
