and 32 show. The males, figure 31, are like most moths well fur- 

 nished with wings and they have a peculiar habit of laying back 

 the antenna, as seen in the figure, and thrusting the fuzzy front legs 

 straight forward. The upper suriace of the front wings is in gen- 

 eral brownish or grayish with darker mai'kings, while the hind 

 wings, as is very often the case, are of a uniform gray-brown. The 

 females are apparently wingless, of a light gray color. They are 

 of the oval form, shown in figure 32. There are very rudi- 

 mentary wings which close examination alone reveals. The eggs 

 are laid on the cocoon and covered by a frothy substance, which 

 when dry is white. The worms appear at various times during the 

 season. It appears from Dr. Lintner's obsei'vations that the growth 

 of those larvae which are to become female moths is continued 

 longer than those which become males, nearly a week. The fe- 

 male lai-vae molt four times, while the male only three. Since the 

 eggs glued to thecocoons are quite easily recognized, hand picking 

 may be readily resorted to when necessary. The usual remedies 

 against leaf-eating insects can be used with advantage in this case. 



The precise scientific name by which an insect is known to ento- 

 mologists, may not be of very great importance to farmers, and for 

 this reason newer names than some of those given in these pages 

 have not been adopted, since the better known term, so long as it is 

 not really obsolete, is better for our purpose. It should, however, 

 be remarked in passing, that it is not certain that the elm-girdling 

 orgyia are the species lencostigina we are considering, but a close- 

 ly allied species known as O de/inata, Pack. The two species 

 have been very much confused evidently, and may need some over- 

 hauling betbre all is made certain respecting them.
