3 c? and 3 9. — This species approaches the typical species of the 

 genus in having the fore wings faintly excavated below the apex, and the 

 hind wings distinctly angulated. In its markings and in the head being con- 

 colorous with the bod}', it approaches the S. calif or niata. Pale ash on the 

 body and wings, the latter more or less dusted with darker scales. Fore 

 wings crossed by three broad dusky bands, inclosing dark venular dots, those 

 in the outer band being conspicuous; this outer band is usually (not always) 

 doubled, the inner ending on the third costal spot, the outer more diffuse 

 and ending in a fourth broader costal spot (this spot is sometimes large and 

 diffuse, sometimes smaller than the third and quite distinct). The marginal 

 row of dots is less interrupted than usual, forming an almost continuous line. 

 Hind wings marked as the anterior pair, with two broad bands, inclosing a 

 row of black spots, the outer band being doubled. Beneath, whitish-ash, 

 with thick brown specks, an oval large discal dot on primaries centered with 

 white, an inner line and an outer double line on both wings; the outer por- 

 tion of the double brown line being wavy and three times as wide as the 

 inner, both wings marked the same, except that the discal dot on hind wings 

 is small and inconspicuous (in one specimen larger and more distinct). 



Length of body, £, 0.42-0.50, 9, 0.50; of fore wing, <?, 50, 9, 0.50; 

 expanse of wings, 1.05 inches.

This not uncommon species" differs from all the other forms by its pale 

 whitish-ash color, the head being scarcely darker than the body, by the fore 

 wings being almost straight below the apex, while the hind wings are very 

 slightly angulated, and by the outer double line, so dark and conspicuous on 

 the under side of the wings, and also by the large oval discal ringlet. The 

 single Alabama male is rather smaller than any of my other specimens, with 

 all the markings very distinct.
