AMERICAN LEPIDOPTERA. 229 



S. velaris, Grt., (Tamila) PL VII, fig. 14. tibia, PL VIII, fig. 24, wing. 



The markings of the wing are well enough shown in the figure ; the 

 ground color is white, the markings are dark yellow with a rufous tinge. 

 Expands 1 inch, 25 millim. 



Habitat. — California. 



S. obliqua, sp. nov. (PL VII. fig. 15, tibia, PL VIII, fig. 25, wing). 



Distinguished from the preceding by the olivaceous tinge in the pri- 

 maries and the distinctly marked reniform. Expands 1 inch, 25-28 

 millim. 



Habitat. — Arizona. 2 £ . 



To the kindness of Mr. Neumoegen I owe my type. A better pre- 

 served specimen is in his collection. 



S. bi fascia, Hb.. Zutr. 1, 14, figs. 55, 56 (PL VIII, fig. 26). 



The tibia are as in the preceding species. It is distinguished from all 

 others in this § by its smaller size, much darker ground color, and the 

 decidedly sinuate narrow white line. Expands J inch, 20 millim. 



Habitat. — Arizona. 



S. nundilia, Dm. 1, 36 (Noctua), pi. fig. 5, vigrirena. Haw., p. 266 (Noc- 

 tua), Guen., Noct. 2, 176 [Tamila); PL VII, fig. 16, tibia, PL VIII, fig. 27, wing. 



A very handsome species, readily recognized by the bright color, and 

 the large black, decidedly constricted reniform. The orbicular is a dis- 

 tinct round spot. 



This species is the type of Tamila, and is very closely allied in all 

 structural points with Shinia, 3 fascia, as a comparison between perfect 

 examples of both will show. Expands 1 inch, 24—28 millim. 



Habitat. — New York (L. I.). 



S. separala, Grt., (Lygranthoecia) Balba, Grt., Papilio 1, 156 [Lygran- 

 thoecia) acutilinea. Grt., Can. Ent. X. 232, and 111. Essay, PL III, fig. 34, {Ly- 

 granthoecia) Walainghami, Hy. Edw., Papilio 1, 20 (PL VII, fig. 17, tibia, PL 

 VIII, fig. 28, primary). 



Rather a variable species, as appears from the synonomy, but there is 

 not the slightest doubt but that they are all color variations of one and 

 the same species. The armature of the anterior tibia is identical in all, 

 and is as shown in the figure. Of separata I had sjieciinens so named 

 by Mr. G-rote, and from the same lot from which came his type. Of 

 balba I have a specimen from Mr. Neumoegen's collection, and I have 

 also examined the type of that species. Of Walsinghami I had Mr. 

 Edwards' type ; a specimen I received from Utah Territory agrees in 

 every respect with the figure of acutilinea in the "111. Essay.'' I am, 

 therefore, in a position to give as intelligent an opinion as a close com- 

 parison <>f types can ever make possible. The figure is from my Utah
