boucheanus Ratz., a common hyperparasite, was also reared from this 

 insect by Dr Lintner. 



Remedies. The spread of this insect is dependent almost wholly on 

 the wandering of the larvae, which must be very limited on account of their 

 cumbersome load. This, in connection with the eggs being deposited in a 

 stout, conspicuous case, which remains on the trees all winter and is easily 

 removed, renders the control of the insect by collecting the bags at this 

 time and burning them, comparatively easy. This caterpillar is a leaf 

 feeder and yields readily to arsenical poisons. Evergreens are quite suscep- 

 tible to arsenic and therefore the arsenate of lead has been recommended.

Dr Smith advises the use of at least 15 ounces of the arsenate to 40 gal- 

 lons of water for the purpose of securing the prompt destruction of the 

 pests.
