INJURY FROM OTHER NON-MIGRATORY SPECIES. 



Having treated of those locusts that occasionally become migratory 

 both on the Alantic and Pacific slopes, we will close this chapter by con- 

 sidering those locusts which occasionally, from causes already explained, 

 become so numerous as to prove positive pests, and do great JDJury to 

 crops in different parts of the country. In this category we must include 

 the few common species already mentioned as proving exceptionally 

 migratory, as well as others which, from the shortness of their wings, 

 are incapable of extended flight, and never become migratory. With 

 ever-changing meteorological conditions, nearly every year some por- 

 tion or portions of the United States become favorable for the undue 

 multiplication of given species, and so, nearly every year, their injuries 

 are reported. 



In 1868 indigenous species were extremely injurious. In Ohio they 

 appeared in countless myriads, and at the meeting of the Cincinnati 

 Wine Growers' Society it was stated that they invaded the vineyards, 

 destroying entire rows, defoliating the vines, and sucking out the juices of 

 the berries. They occurred in countless millions in many parts of Illi- 

 nois and Missouri, and actually stripped many corn-fields in these States, 

 and, had not the crops been unusually abundant, would have caused 

 some suffering. They were also very destructive to flower and vegeta- 

 ble gardens. 



In 1869 they were even worse than in 1868. In the vicinity of Saint 

 Louis they were particularly annoying, stripping the tops of Norway 

 Spruce, Balsam Fir, and European Larch, and devouring the blossoms 

 off Lima beans. They severed grape stems and ate numerous holes 

 into apples and peaches, thereby causing them to rot. Their ravages 

 for this season, however, seemed to be confined to the West, as they wer j 

 more particularly abundant in Illinois, Missouri, Iowa, and Kentucky. 

 During this year locusts attracted little attention in the Eastern States, 

 but two years afterward they did much damage there, as may be seen 

 by the following items : 



The grasshoppers (locusts) have been more numerous and destructive this year, in 

 Maine, than perhaps ever before. This was partly owing to the dry weather, and 

 with the advent of the rainy season we hope their career will be somewhat checked. 

 In this county they are thick, but in some of the central portions of the State they
