breeds in considerable numbers under purslane, amaranth, etc., and 
more than any other insect resembles the chinch bug. It is, however. 
of a light-gray color, which will always distinguish it from its more 
destructive fellow. 
Ischnodi in us falicus Say. or the long chinch bug, as it is sometimes 
called, is much lamer and longer than the true chinch bug. 
I schnorhynchus didymus Zctt. is more robust, of 
a light-tawny color, with prominent, glassy wings. 
Peliopelta abbreviata Uhl. is, next to the false 
chinch bug, probably the most often mistaken for 
the true insect, and especially is this true in local- 
ities wIktc the brachypterous form of Blissus 
leucopterus al^unds, viz. in timothy meadow-. Its 
broader head and body, however, quickly enables 
one to distinguish it. 
Geocoris fuliginosus Say, G. borealis Dallas, G. 
bullatus Say. and G. limbatus Stal, according to 
( )sborn and Mally, have all been confused with the 
chinch bug in Iowa. These are all broader and flatter than the true 
chinch bug. the head being nearly as wide as the thorax. 
Ligyrocoris sylvestris L. is larger than the true chinch bug, and 
it- wing- are quite dark instead of white. 
Trapezonotus nebnlosus 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 a 
light brown color, and the ends of the wings are glas-y. 
I'ri />Jtl< /as- insidicsus Say. or the insidious flower bug (fig. 15). as 
it is more commonly called, is another bogus chinch bug. though an 
enemy of the true pest, as previously stated. 
Piesma cinerea Say. the ash-gray leaf bug (fig. 7). is often mis- 
taken 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. 
Corimelcena pulicaria Germ., the flealike negro 
bug (fig. 8), ha- been confused with the chinch 
bug: though it doe- not in the least resemble the 
latter, either in form or color, and it- confusion is 
probably to be accounted for by the fact of its being occasionally 
Pound in wheat fields in considerable numbers. 
Braehyrliynclms granidatus Say (fig. 9) 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 L896-97, were burn- 
ing over the woodland- with a view to destroying the hibernating 
insects, when there came several discouraging reports to the effect 
that such a course would be ineffective, a- the bugs were wintering
