Il8 HEMIPTERA-HETEROrTERA. 



and about five hundred in number. The female is 

 three weeks laying them. They require about two 

 weeks to hatch. 



The larvae are red, and, at first, feed upon the roots 

 of the plants which they infest, sucking their juices; 

 afterwards they attack the stalks. The bug becomes 

 full grown in from forty to fifty days. 



This species is two or more brooded and hibernates 

 in the perfect state. It infests the different kinds of 

 grain, destroying the small grains first, then attacking 

 corn. 



Although the perfect insect has well developed 

 wings, it seldom uses them for flight. 



Note habit of marching from one field to another. 



This species is dimorphic, there being a short 

 winged form. 



Natural enemies. — Several species of lady-birds, the 

 Weeping Lacewing {Chrysopa plorabunda Fitch), the 

 Insidious Flower-bug {Atithocoris insidiosus Say), and 

 the common Quail. 



Remedies. — Burn corn-stalks, and rubbish along 

 fences, in order to destroy the bugs that are hibernat- 

 ing in those places. In case a field of grain is so badly 

 infested as to be not worth harvesting, do not fail to 

 burn it. With twelve bushels of spring wheat mix 

 one bushel of winter rye. The bugs will destoy the 

 rye in preference to the wheat. Note manner of stop- 

 ping their march with boards, and of trapping them in 

 pits. (5, I., 169; 3, II., 15; 4, II., 277). 



The Squash-bug, Coreus iristis De Geer. — Eggs laid 

 in June, in little patches, on the leaves. Young bugs 

 short and more rounded than the adult insects, and of
