vary from pale-yellow with a touch of orange to bright- 

 red, while the pupa (</,) is mostly brown, the 

 mature bug (fig. 79,) is black, with white upper wings, 

 having two characteristic black spots upon them. A 

 short- winged form (fig. 80,) occurs in Canada, and in the 

 more Northern States. The species hibernates in the 

 perfect or mature form in a state of torpor in whatever 

 sheltered situations can be found. 



The Chinch-bug is two-brooded in the Middle States, 

 and in the more Southern States is probably three-brooded.

Such as survive the autumn, when the plants or the 

 sap on which they feed are mostly dried up, so as to afford 

 them little or no nourishment, pass the winter in the 

 usual torpid state, and always in the perfect or winged 

 form, under dead leaves, under sticks of wood, under flat 

 stones, in moss, in bunches of old dead grass or weeds or 

 straw, and often in corn-stalks and corn-shucks. One 

 year I repeatedly received corn-stalks that were crowded 

 with them, and it was difiicult to find a stalk in any field 

 that did not reveal some of them, upon stripping off the 

 leaves. 



It has long been known that the Chinch-bug deposits 

 its eggs underground and upon the roots of plants which 

 it infests, and that the young larvse remain underground
