specimen and from a specimen in Mr. Tepper's collection, holding the 

 middle between acutilinea and separata. Balba and Walsinghami are 

 exceedingly close together, and vary in the pale dull color of the former, 

 and the more reddish yellow of the latter from the type. There is a 

 decided variation in the course of the subterminal white lines, and, in 

 fact, in all the lines, but in the large series before me I can pick out all 

 the species and intergrades between them. I can find separata colored 

 like Walsinghami, and acutilinea colored in the same way. I notice 

 also that all the variations seem local — ■ Walsingham is from Oregon, 

 balba is from Arizona, separata from Nevada, and acutilinea from Mon- 

 tana and Utah Territory. At best they are only indistinct varieties and 

 scarcely entitled to be catalogued as such. Expands 1-1 \ inches, 24-30 

 millim. 



Habitat as above.

Readily distinguished from all the others in this § by the yellow secon- 

 daries. The markings of the primaries are shown by the figure. A form 

 in Mr. Graef's collection has the primaries saturate with reddish, but 

 evidently belongs to this species. Expands | inch, 20-22 millim. 



Habitat. — Georgia and North Carolina. 



S. satlirata, Grt.. Buf. Bui. 2, 74 (Lygr.); rubiginosa, Strk., Lep. 122 (He- 

 liothi*) ; PL VIII, fig. 27, wing. 



Separated from all the preceding by the reddish color of primaries, 

 scarcely contrasted median space bounded by narrow crenulate white 

 lines, and by the uniform pale reddish secondaries. The rubiginosa. form 

 of Mr. Stccker differs from the saturata form by the paler, more uni- 

 form reddish color, but is undoubtedly the same as Mr. Grote's species. 

 Expands 1 inch, 24 millim. 



Habitat. — Kansas and Southern California. 



S. sordidus, sp. nov. 



Primaries pale chocolate brown, extreme base, narrow median shade 

 and apical spot paler, more yellowish ; median shade with a roseate tinge ; 

 the space is narrow, bounded inwardly by a distinct crenulated white line ; 

 outwardly by a like but more even white line, making a bold curve out- 

 wardly around the reniform, and from the middle of the wing running 

 parallel with the interior line to inner margin ; reniform distinct, but 

 not sharply bounded ; from the apical pale spot an indistinct sinuate 

 yellowish subterminal line extends to the bind angle; secondaries black.
