line of (lots is very distinct, and contiuurd on to tlic liind wings. Certain 

 specimens have a pale hue, with a slight yellowisli tinge, and were originally 

 described as a distinct species nnder the name paJlldnta. I append the 

 original description : 



3 i and -1 9. — A pale cinereous species, with the outer edge of fore 

 wings straight, not excavated, the hind wings rounded, not angulated. Head 

 and palpi pale, concolorous with the body. Fore wings crossed by three rows 

 of venular dark dots, ending in three costal larger spots, the outer row angu- 

 lated just l)elow tlie costa ; tlu> fourth spot beyond (usually present) wanting. 

 A faint ditl'use brownish shade beyond the outer row of dots (often wanting). 

 Both wings speckled slightly witli brown. Discal dots on both wings brown. 

 Till" usual marginal row of dots. Fringe concolorous with the wings. A 

 flint dusky dilfuse band near the edge of hind wings. Beneath, the wings 

 are heavily speckled with pale l)rown ; costa and veins ochreous ; discal dots 

 larger and distiucter than aixive ; the outer line usually reproduced and double. 

 A snbniarginal broad diffuse shade often present on hind wings. 



Length of body, i, 0.41, 9, 0.40; of fore wings, <? , 0.47, 9, 0.50 inch. 



Texas, April P.O to May 23, September 15 (Belfrage). 



Four i)f these specimens are whitish, a single female much darker, and 

 with the sulinun-ginal l)and present on hind wings.

 This species is very similar to S. c<iiif<i/)iiaf(i, but differs in its larger 

 size, the pectinated antenna;, and in other respects. It is of the same color 

 above and beneath, lieing slate-gray, with the veins quite prominent. The 

 antenna' are well pectinated; three heavier dark-brown costal spots than in 

 S. califoniiata. The third spot is a little larger than the others, and nearly 

 touches a large, dark, conspicuous patch, broken up into I'onr spots, situated 

 just l)eyond the origin of the median venules. A pale sinuous line nnis 

 from this patcli to the iuiu-r edge of the wing; traces ol' similar lines run 

 across the wing ironi the two inner costal spots. The liind wings differ ti-om 

 those of ^'. cr(///or«/«/« in having a straight, dark, well- nuirked extradiscal line. 

 Beneath, gray, mottled with whitish spots, much as in *S'. atliforniata, with 

 traces of a diffuse pale line, common to both wings. 



Length of body, S , ()l\i); of fore wing, i , 0.60; expanse of wings, 1.20 

 inches.
