4 <? and 4 9. — In a male received from Mr. Behrens, the wings are 

 clearer, the outer line less distinct; the dusky cloud near the internal angle 

 of the wing is wanting, and the fringe is slightly checkered as in the female; 

 the hind wings are crossed on the under side by a well-marked curved band 

 of large brown spots, and the under side is of a paler ashen-gray than in the 

 other specimens. 



The male differs from the female in the fore wings being clearer beyond 

 the outer broad band, and in not having the large dark patch below the middle 

 of the wing (present in the male), while the outer edge of the hind wings 

 is clearer ; but it differs most in having the fringe checkered with white and 

 dusky -brown. A faint band on the under side of the hind wings, sometimes 

 not present in either sex. A variety, originally described as a distinct species, 

 is californiaria. It is usually pale-ash, bathed on the fringe and beneath 

 with reddish-pink; the palpi are longer and scales of front rougher thai 1 

 in S. juturnaria, otherwise it is structurally the same, though larger. Fore 

 wings crossed by a single curved, diffuse, dusky line, beginning on the 

 outer third of costa, and curving and fading away before reaching the inner 

 edge; this slightly-marked line being more regularly curved than in S.jutur 

 nana. No discal dot seen above. Hind wings free from markings, fringe 

 pinkish, and both wings beneath bathed with reddish-pink. On fore wings, 

 a linear, small, discal dot ; on hind wings, a larger, rounded, discal dot. No 

 band on hind wings, or any other markings or dusky scales, and on the fore 

 wings is a faint reproduction of the single outer line, disappearing before 

 reaching the middle of the wing. 



It may be at once recognized by the red fringe and under side of wings. 



Length of body, c*, 0.65-0.70; fore wing, <?, 0.75-0.86; expanse of 

 wings, 1.60 inches.
