pea crop in some localities. The following year they made havoc 

 with the winter wheat in Washington county, Illinois, in September, 

 devouring the plants when they were two or three inches high ; and 

 some small damage was also done to corn. In Mr. Eiley's report 

 for 1881 and 1 82, the first and second generations are said to lay 

 their eggs on the growing stalks of rice. The worms, hatching, 

 "rag" the plants badly, and when in great numbers eat them to the 

 ground. Grass, cabbage, strawberries, and beans were among the 

 plants injvired in Georgia during this year by a later brood. 



In Central Illinois, this fall, the injuries were confined, as far as 

 our observation extended, to old oats ground, with the exception of 

 a field or two formerly in wheat, on which volunteer grain had 

 sprung up in extraordinary quantity. We could hear of no damage 

 noticed in the fields of oats early in the season on ground after- 

 wards visited by the grass worm when cropped in wheat. In very 

 many cashes the loss was total, and many thousand acres of winter 

 wheat were entirely killed by the worms in the area infested this 

 year. Most of the fields were plowed and resown, but occasionally 

 one was left. The destruction of a whole field was rarely complete, 

 the bare area being usually in bands and patches, in the center of 

 which the plants were eaten to the ground, while around the mar- 

 gins the damage was less severe. Where the wheat was early sown 

 and had reached a height of five or six inches, stubs of an inch or 

 more were left by the worms, and from these the plant partly revived. 



The number of worms in a field, as indicated by the pupfe dis- 

 coverable in the ground, was about six to ten to a square foot ; 

 although some farmers asserted that a handful could have been 

 gathered, earlier, in their fields by a single sweep of the hand. 



From Mr. Harris, of Cuba, I have received the following detailed 

 account of the method and amount of the injury done in a field 

 under his observation :
