"Wheat, so long the leading crop of the State, has hardly lost 

 its prestige. * * * The ravages of its enemy, the chinch bug 

 {Micropus leucoptervs of Say), were extensive in 1861, 1865, and 

 1866, but the extremely cold winters that succeeded, or other nat- 

 ural causes, have nearly exterminated it."

"The hair}^ caterpillars are eaten by very few birds; and the 

 nauseous Hemiptera, such as the squash bug (Coreus) and the 

 chinch bug, are, I believe, rejected by all."
