66 REVISION OF XYLOMIGES AND MORRISONIA—SMITH. 
I place at the head of the series the species in which the male an- — 
tenne are pectinated, the primaries moderately wide, trigonate, the 
apices well marked. 
Hiemalis is a small species in which the median lines are usually not 
well marked. The ordinary spots are distinct, the reniform is marked 
with reddish, and there is a distinct curved basal dash, above which 
there is a Somewhat prominent paler shade. The antennal pectinations 
are very long, and there is a series of black spots before the s. t. line. 
‘Peritalis is larger, with much the same type of maculation. There 
are no shades or spots before the s. t. line, and the antennal pectina- 
tions are much shorter. 
Orucialis is a much paler form than any of the preceding, somewhat. 
smaller than peritalis, from which it differs in having the darker ter- 
minal space completely cut on veins 3 and 4, leaving two triangular 
blackish patches. 
To the second series, in which the male antenna are serrate and cili- 
ate, belong curialis, dolosa, perlubens, subapicalis, rubrica and ochracea. 
Curialis and dolosa are narrow-winged forms, like the European 
species, the colors dark ash gray. In cwrialis the color is even, with a 
faint reddish suffusion and no white lines or patches. 
In dolosa the color is powdery, blackish, the orbicular white ; below it 
a white band extends to the inner margin, giving the wing a charac- 
teristic appearance. Thes, t. line is also white, or paler at least. 
Perlubens I do not know. Mr. Grote says it is related to rubrica, 
and so it seems to be. It is not possible to specify exactly wherein it 
differs, from the description, except that the orbicular is said to be up- 
right. Inrwbricait is oblique, elongate, in all the specimens seen by me. 
Rubrica and subapicalis are broader winged than curialis and dolosa, 
and the outer margins are obviously dentate, which is not the case 
with the latter. 
Rubrica is a powdery, reddish gray form, sometimes almost even in 
color, sometimes quite strongly maculate, the ornamentation taking 
form as a distinet preceding shade to s. t. line, sending in a black shade 
opposite the cell, so as to relieve and lighten the apical region. The 
orbicular is elongate, oblique, oblong, and gray in color. The insect 
looks like a Teniocampa at first sight, and the generic characters are 
not strong. 
Subapicalis I once thought a form of rubrica, and so described it. It 
differs, however, not only in the sexual characters, but in the uniformly 
ash or blackish gray ground color, and in the form of the orbicular, 
which is upright and broadly oval. In other details of maculation it is 
like rubrica. This species looks as much like a Mamestra as rubrica 
does like Teniocampa, and well illustrates the artificial character of 
the hairy eyed genera. 
Ochracea is unlike any other of the species. It resembles patalis in 
wing form; but is of a dull, luteous, ground color, with the veins
