Syntomidae 
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.

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 
latitude of New York City and Pittsburgh frequenting the blos¬ 
soms of blackberries at the end of May and in June. The larva 
feeds, as do the larvae of the other species, upon grasses.
