Within the angle of the outermost 
whitish band, near the front edge, 
there ts a short, faint, blackish hne, 
following a nervure; and there is a 
row of black dots along the outer mar- 
gin, close to the fringe. 
The hind wings are pale ash-colored, 
or light gray, with a faint blackish dot 
near the middle. 
In most specimens a curved white 
band is plainly visible on the hind 
wings, about half way between the 
middle and the end. 
The outermost white band of the 
fore wings, with its angulation, and 
the band of the hind wings, are also 
visible on the under side of the 
wings. Within the angulation is a 
brown or blackish spot on the costa. 
The wings expand about one inch 
and a quarter (32 millimeters), vary- 
ing between 26 and 34 millimeters, 
and predominating at 30 millimeters. 
Antenne of the female naked. 
Abdomen not terminating in an ovi- 
positor, rather bluntly tapering be- 
hind. 
Whole body and legs of the female 
smooth, clothed with glistening brown 
and white truncate scales intermixed, 
giving it an appearance of uniform 
shiny dark ash-color aboye and gray 
beneath.

There is an oblique, blackish dash 
near the tip of the fore wings, cross- 
ing a nervure; and there is a dis- 
tinctly interrupted or nearly uniform 
continuous line of blackish along the 
outer margin, close to the fringe. 
The hind wings are pale ash-colored, 
or very light gray, with a faint black- 
ish dot near the middle. 
The white band found on the hind 
wings of A. vernata is wanting. 
On the costa, opposite the begin- 
ning of the outermost dark band of 
the upper surface, and on the edge of 
the disk, are dark spots on the lower 
surface of the wings. Along the 
median nervure beneath is a dark 
line. These marks are sometimes 
indistinct. 
Of a rather smaller size than A. 
vernata, varying between 22 and 33 
millimeters,! and predominating at 
29 millimeters. 
Antenne of the female pubescent. 
Abdomen terminating in a retrac- 
tile ovipositor, rather acutely taper- 
ing behind. 
Whole body and legs of the female 
pubescent, clothed with whitish and 
brown or black dentate scales or

A black band along the middle of the 
back of the abdomen, often inter- 
rupted on the second to seventh 
rings; with a whitish patch each side 
of its front end; the spines frequently 
giving a reddish appearance to the 
part they occupy. 
Crest of prothorax and mesothorax 
black.
