AMERICAN LEPIDOPTERA. 235 



Rather a formidable synonoiny for a common insect, and it should 

 indicate a considerable variation in the species. This, so far as I am 

 aware of, does not exist, but on the contrary it seems remarkably con- 

 stant. Much like the preceding superficially, but the colors are more 

 contrasted, and the lines are wider and not crenulate. Expands 1 inch, 

 26 millim. 



Habitat. — Middle States. 



S. constricta, Hy. Edw., Papilio, 2, 128 {Lygranthoecia) ; PL VII, fig. 32, 

 tibia, PI. VIII, fig. 42, wing. 



Entirely peculiar in its marking, which I leave to the figure to explain. 

 It is closely related to the preceding, while easily separated from it. Ex- 

 pands 1 inch, 26 millim. 



Habitat. — North Carolina. 



S. Brevis, Grt., Proc. Am. Ent. Soc. 3, 530, PI. VI, fig. 4; Buf. Bui. 2, 34 

 (Melicliptria) ; var. Atrites, Grt., Buf. Bui. 1, 119, PL VII, fig. 33, tibia, PL VIII, 

 fig. 43, wing. 



Widely distinct from the species immediately preceding so far as super- 

 ficial appearance is concerned, and readily distinguished by the propor- 

 tionately small wings ; the primaries of a deep brown, variagated with 

 paler colors, as in figure ; the secondaries usually black with a yellow 

 band, which in the var. Atrites is wanting. Expands f to i inch, 20-23 

 millim. 



Habitat. — Colorado. 

 S. erraus. sp. nov. PL VII, fig. 34, tibia, PL VIII, fig. 44, wing. 



This species is the one usually labelled nobilis in collections, and I 

 have seen the species so labelled in Mr. Grote's handwriting. It bears 

 some resemblance to the type of nob His in the Philadelphia collection, 

 but is evidently distinct by the armature of the anterior tibia. It is 

 related to the preceding in form, but diners in color and markings; the 

 latter are olivaceous on a luteous ground, arranged as shown in the figure. 

 Expands i inch, 24 millim. 



Habitat. — Arizona. 



S. inclara, Strk., Lep. 122 (Heliothis); Grt. New List (Anthoecia); PL VII, 

 fig. 35, tibia, PL VIII, fig. 45, wing. 



Resembles the preceding in form and color, but differs evidently in the 

 pattern of the marking as shown in figure. Expands as before. 

 Habitat. — Texas. 



S. M eskeana, Grt., Can. Ent. 7, 224 ; fastidiosa, Strk., Lep. 121 {Heliothis) : 

 Grt., Papilio, 1, 157 {Lygranthoecia); New List {Anthoecia) ; rujimedia, Grt., Bkln. 

 Bui. 3, 31 ; PL VII, fig. 34, tibia, PL VIII. fig. 46, wing. 



Of rujimedia I have the type from Mr. Hulst's collection ; of Meske-
