ENEMIES OP BKEy. 229 



from five-oightlis to three-quarters of an inch in length, 

 and its wings expand from one inch and one-tenth to one 

 inch and four-tenths. The fore-wings shut together flatly 

 on the top of the back, slope steeply downwards at the 

 sides, and are turned up at the end somewhat like the 

 tail of a fowl. The female i-s much larger than the male, 

 and much darker-colored. There are two broods of these 

 "insects in the course of the year. Some winged moths of 

 the first brood begin to appear towards the end ^f April 

 or early in May — earlier or later, according to climate and 

 season, "f hose of the second brood are most abundant in 

 August ; but some may be found between these periods, 

 and even much later." 



No writer with whom I am acquainted has given such 

 an exact description of the difference between the sexes, 

 that they can always be readily distinguished. The 

 beautiful wood-cuts of the moths, larvse, and cocoons, 

 which I present to my readers, were drawn from nature, 

 by Mr. M. M. Tidd, of Boston, Mass., and engraved by 

 Mr. D. T. Smith, of the same city. A large number of 

 specimens were furnished to Mr. Tj.dd, 

 and great accuracy has been secured. 

 He seems first to have noticed that the 

 Female tougue of the female projects, so as 



to resemble a beak, while that of the 

 male is very short.* 



While some males are larger than some females, and 



some females much lighter-colored than 



the average of males, and occasionally 



some males as dark as the darkest 



J. , females, the peculiarity of the tongue 



■ of tJie female is so marked, that she 



m.ay always he distinguished at a glance. 



* Dr. Harris speaks of tie tongue of the moth as "very short, and hardly 

 visible." Thisis tree only of that of the male.
