Syntomidse 



From Ctenucha cressonana, its nearest ally, this species may 

 be distinguished by its smaller size, the reddish tint of the stripes 

 upon the fore wings and the edges of the shoulder lappets, and 

 the fact that the fringe opposite the end of the cell on both wings 

 is marked by fuscous, and not uniformly white throughout 

 as in C. cressonana. The species ranges from Colorado to 

 Mexico. 



(2) Ctenucha cressonana Grote, Plate XIII, Fig. 21, $. 

 (Cresson's Ctenucha.) 



This species, which is one of the largest in the genus, may 

 easily be recognized by the figure we give and the remarks 

 made in connection with what has been said in regard to the 

 preceding species. 



(3) Ctenucha brunnea Stretch, Plate XI, Fig. 6, $ . (The 

 Brown-winged Ctenucha.) 



Easily recognized by the pale brown color of the primaries, 

 upon which the veins stand forth in a darker shade of brown: 



(4) Ctenucha multifaria Walker, Plate XIII, Fig. 19, $. 

 (The Californian Ctenucha.) 



This species, which is closely allied to the next, may be dis- 

 criminated by the fact that the fore wings are lighter in color, 

 the collar is black, not orange spotted with black, as in C. 

 rubroscapus, and the costal margin of the primaries is nar- 

 rowly edged with white. 



(5) Ctenucha rubroscapus Menetries, Plate XIII, Fig. 

 22, $ . (Walsingham's Ctenucha.) 



Syn. walsinghami Henry Edwards. 



This species, which may be distinguished by the aid of what 

 has been said under the preceding species, as well as by our 

 figure, may have the edges of the shoulder lappets either red, as 

 in our figure, or orange yellow. It is found in the Pacific States. 



(6) Ctenucha virginica Charpentier, Plate XIII, Fig. 18, $ . 

 (The Virginian Ctenucha.) 



Syn. latreillana Kirby. 



This moth, which is not at all uncommon in the northern 

 portions of the Appalachian faunal region, may be found in the 

 tetitude of New York City and Pittsburgh frequenting the blos- 

 scms of blackberries at the end of May and in June. The larva 

 feeds, as do the larvae of the other species, upon grasses.
