74 CHINCH-BUG FAMILY. 
lay their eggs; this they do leisurely, the process being carried 
on for two or three weeks. The eggs are yellowish; about 500 
are laid by a single insect; they are deposited in fields of grain, 
beneath the ground upon the roots, or on the stem near the sur- 
face. The eggs hatch in about two weeks after being laid. The 
newly-hatched bugs are red; they feed at first on the roots of 
the plants which they infest, sucking the juices; afterwards they 
attack the stalks. The bugs become full-grown in from forty to 
fifty days. Before the females of this brood deposit their eggs 
they leave their original quarters and migrate in search of a more 
abundant supply of food. About this time the wheat becomes 
dry and hard; and the migration appears to be a very general 
one. Although the insects sometimes go in different directions, 
as a general rule the masses take one direction, which is towards 
the nearest field of corn, oats, or some other cereal or grass that 
is still in the succulent state. At this time many of the bugs have 
not reached the adult stage; and even in the case of the fully 
winged individuals the migration is usually on foot. In their 
new quarters the bugs lay the eggs for the second or fall brood. 
“Satisfactory means for preventing the ravages of this in- 
sect are yet to be discovered. Something can be done by burn- 
ing in autumn all rubbish about fields, in fence-corners, and in 
other places where the bugs have congregated to pass the winter. 
The marching of the spring broods into new fields has been 
stopped by means of ditches, as is done with the army worm. 
Some farmers have accomplished the same purpose by making a 
line of gas-tar on the ground; the bugs will not pass such a 
line, but it is necessary to replace it frequently. In some cases 
kerosene emulsion can be used to advantage.” 
To this may be added that possibly the chinch-bug may only 
be single brooded in some localities, and that it is frequently al- 
most annihilated by a number of diseases, one of which is shown 
in Fig. 67. 
In the small sub-family Nysiina we have a few well-known 
species, some of which are sometimes almost as abundant as the 
genuine chinch-bug, and for that reason have received the name 
of “Bogus Chinch-bug” or “False Chinch-bug.” 
Nysius angustatus Uhler, (The False Chinch-bug) is a very 
general feeder, and sometimes decidedly injurious, as it is found
