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 l^ody 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 way a butterfly holds its wings. After 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 (juick and erratic flight is 

 similar to that of other moths of this famih'. 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 li to 19 mm. Commonly speaking, the}" 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 large 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 they appear golden. Near the ocellus there is a very 

 daris;-brown 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 by 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 diflicultto 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
