Ligyrocoris sylvestris Linn, is larger than the true chinch bug. and 
its wings are quite dark instead of white. 
Trapezonotus nebulosus Fall, is a trifle larger and its body is not so 
black as in the chinch bug. 
Cymodema tabida Spin., is longer than the true chinch bug, of alight 
brown color, and the ends of the wings are glassy. 
Triphleps insidiosus Say, or the insidious flower bug 
(fig. 11), as it is more commonly called, is another bo- 
gus chinch bug, though an enemy of the true pest, as 
previously stated. 
Piesma cinerea Say, the ash-gray leaf bug (fig. 11) is 
often mistaken for the true chinch bug, though its 
form differs greatly from that of the latter. It is often 
quite abundant, but not in grain fields or meadows.

fact of its being occasionally found in wheat fields

Brachyrliynclius g rani flat us Say (fig. 1G), has been 
mistaken for the chinch bug in Ohio, and in a way that was somewhat 
amusing. Farmers in southern Ohio, during the winter of 1S96-97, were 
the woodlands with a view of de- 
hibernating insects, when there

where the tops were 
dead, under the bark
