wing-covers and wings, and brown eyes and feet. Its life-history 

 closely resembles thai of Erytlm '& of the grape. 



Perhaps the best preventive of injury by this inseel is an infu- 

 sion of tobacco, prepared in the following manner: Where the 



tobacco stems can be procured, place some of them in a vessel of 

 the capacity of a common pail and pour boiling water upon them 

 until they are covered. Allow it to stand over night, and when 

 used dilute it with five times the quantity of water and apply it 

 to the underside of the leaves with a garden syringe, or force 

 pump with a rose nozzle. The application should be made in the 

 evening, or early in the morning, and, particularly, early in the sea- 

 son, before the injuries become noticeable except from close exam- 

 ination, and as soon as the young larva 1 , looking like little white 

 specks, are discoverable on the underside of the leaves. The shower- 

 ing should be repeated from time to time so long as the insects 

 remain or the effects of their presence are noticeable. 



I had intended asking your attention to a few other insect pests 

 which are annually demanding heavy tribute from you, and wmich 

 yon are voluntarily paying, — not necessarily, for recent discov- 

 eries in economic entomology have given means which only need to 

 be properly used in order that the burden of insect injuries shalL 

 be materially lightened; but I have already exceeded the time- 

 allotted for my paper. 



May I hope that the details presented — some of which I fear 

 may have been found dry — may not have greatly wearied you.
