32 THE CHINCH BUG. 
breeds in considerable numbers under purslane, amaranth, ete., 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. 
Ischnodemus falicus Say, or the long chinch bug, as it is sometimes 
called, is much larger and longer than the true chinch bug. 
Ischnorhynchus didymus Zett. 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 where the brachypterous form of Blissus 
leucopterus abounds, viz, in timothy meadows. Its 
broader head and body, however, quickly enables 
one to distinguish it. 
Geocoris fuliginosus Say, G. borealis Dallas, G. 
Fie. 7.—Piesma cm byllatus Say, and G. limbatus Stal, according to 
erea. (From Riley.) 
Osborn 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 ia is larger than the true chinch bug, and 
its wings are quite dark instead of white. 
Prapesonotus 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 a 
light brown color, and the ends of the wings are glassy. 
Triphleps insidiosus 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 chinech bug, though its form 
differs greatly from that of the latter. It is often 
quite abundant, but not in grain fields or rt 
meadows. 
Corimelena pulicaria Germ., the flealike negro 
bug (fig. 8), has been confused with the chinch * 
bug; though it does not in the least resemble the Pais tee Bienes 
latter, either in form or color, and its confusion is 
probably to be accounted for by the fact of its being occasionally 
found in wheat fields in considerable numbers. 
Brachyrhynchus granulatus 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 1896-97, were burn- 
ing over the woodlands with a view to destroying the hibernating 
insects, when there came several discouraging reports to the’ effect 
that such a course would be ineffective, as the bugs were wintering
