of eggs, with a ring of soft, liglit-brown, silky liair 

 near the tail. (See fig. 113, c). 



The female never withdraws herself entirely from the 

 pupa shell, but holds on to it by her terminal segments, 

 being evidently assisted by the ring of woolly hair already 

 referred to. Thus, with the pupa shell extended to its 

 utmost capacity, and the additional length of her whole 

 body, she is enabled to reach to the lower orifice of the 

 follicle, where she pertinently awaits the male, and after 

 meeting him, works herself back into the pupa shell. 

 Here she deposits her eggs in the upper part, interming- 

 ling them, and crowding the lower part of the puparium 

 with the peculiar fawn-colored down already referred to. 

 After having thus cosily secured her eggs against the 

 winter's blasts, she works herself out and drops ex- 

 hausted to the ground. 



This insect is a general feeder, for it occurs alike on 

 evero^reen and deciduous trees. We have found it on 

 the Apple, Plum, Cherry, Quince, Pear, Ked and White 

 Elms, the common Black and Honey Locusts, Lombardy 

 Poplar, Catalpa, Norway Sj^ruce, Arbor-vitse, Osage 

 Orange, Soft and Silver Maples, Sycamore, Linden, 

 and above all, on the Eed Cedar, while Mr. Glover has 

 also found it on the Cotton plant in Georgia. We have 

 even seen the bags attached to Easpberry canes. 



This insect is also exceedingly hardy and vigorous, and 

 the young worms will at first make their bags of almost 

 any substance upon which they happen to rest, when 

 newly hatched. They will construct them of leather, 

 paper, straw, cork, wood, or of any other material which 

 is sufiiciently soft to allow of their gnawing it, and it is 

 quite amusing to watch their operations. 



Eemedies. — How often does the simple knowledge of 

 an insect's habits and transformations, give the clue to its 

 easy destruction! From the foregoing account of the 

 Bag-worm, it becomes obvious, that by plucking and
