ish scales running outwardly to where the outer component line would be if it 
were present. Subterminal line faint, merely indicated by the paler terminal 
space, preceded by a darker shading which forms a determinate blackish costal 
shade before the line. A pale line at base of the dusky fringes. Hind wings 
dusky, a little paler and semi-hyaline at base, nearly like the primaries in tint, 
with no determinate border or discal mark save by reflection from the under- 
surface. Fringes with a pale basal line. Beneath paler, more whitish ; luni- 
form discal mark on hind wings distinct, black, fainter on fore wings. A com- 
mon exterior darker shade line with faint traces of a subterminal shade. Head 
and thorax dusky ashen; abdomen concolorous with hind wing. Feet and 
tibiae blackish, pale dotted.

6 ?.—Resembles the foregoing so that a comparative description will best 
distinguish it. Larger than subgothica, of a purplish black color, and hence 
much darker than subgothica, with which it coincides in the ornamentation of 
the primaries above. The t. a. line below the median nervure is more outwardly 
rounded, less perpendicular ; the prominent claviform is shorter. The ordinary 
spots are similar in the two species, but the reniform is discolorous in 
subgothica, stained with ochreous, with a distinct internal ring, whereas the 
internal ring is feebly marked and the spot is simply pale carneous, like the 
orbicular and the pale nervular squamation, in herilis. The t. p. line is more 
distinct and black in the new species. Hind wings smoky blackish, deepening 
in color terminally, not pale with a hind border as in subgothica. On the fore 
wings above there is a notable contrast between the paler subterminal space 
and the extended paler marginings to veins 3 and 4 in subgothica, and the 
obscurely carneous coloration of the same parts in the new species, which latter 
wants the decided prolongation of pale scales along the inferior veins. 
Expanse, 38 to 43 m.m. Habitat, Atlantic District ; of common 
occurrence. I have taken this species in Central Alabama.
