awa}^ the head end of the pupal skin. The legs, antennae, and wings 
are drawn out of their sheaths. The insect is wet, and the bod}^ wall 
is soft. The wings increase several times in size, and as the body dries 
it grows more rigid. A few moths were observed to have emerged in 
the field. During the process of expanding and growing they clung 
to the bark of the trees with their heads up (PI. VI, fig. 1), avoiding 
the sunlight. When the wings were fully expanded the moths would 
often hold them over their backs for a few minutes, in a manner simi- 
lar to the wa\' a butterfly holds its wings. Af tei.\ running about over 
the tree for a short time the moths fly into the lower branches of the 
trees, and are lost to observation. Their quick and erratic flight is 
similar to that of other moths of this family. The whole process of 
emergence takes from fifteen to thirty miiuites. 
THE ADULT INSECT. 
The adult insect or moth is quite variable in size. The wings 
expand from 14 to 19 mm. Commonly speaking, they never expand 
over three-fourths of an inch. The whole insect is covered with scales 
in varying colors. The tip of the front wings bears a lai-ge dark- 
brown spot or ocellus on which there are two irregular broken rows 
of scales, which have a coppery metallic color, and with some reflec- 
tions of light the}^ appear golden. Near the ocellus there is a very 
darii-bro«^n band across the wing, which is more or less triangular in 
outline. The remainder of the wing is crossed by irregular dark and 
white bands, an appearance caused by the white tips on the dark scales. 
In many specimens there is a distinct darker band across the wing, 
while in others this band is not apparent. The hind wings are a 
grayish-brown color, darker toward the margin, with a long black line 
at the base of the fringe. The underside of the hind wings has 
dark, irregular, transverse markings. The underside of the front 
wings is of a light-brown color, with opalescent reflection and with a 
few markings except on the costa. The legs and head and patagia are 
covered with long, narrow, white-tipped scales, while the body is 
covered with white-colored scales with opalescent reflections. The 
large white scales on the caudal margin of the abdominal segments 
are especially conspicuous. (PI. VII.) 
HOW TO DISTINGUISH THE SEXES. 
There are many characteristics ])y which the males and females may 
be easily distinguished. As stated by Zeller, the males have penciled, 
long, black hairs on the upper side of the hind wings. These hairs are 
sometimes of a light color, which renders them difiicult to distinguish. 
Slingerland discovered that the males could also be distinguished by 
the presence of a distinct elongate, blackish spot on the underside of 
the fore wings, which spot consists of a number of black scales. These
