DEVELOPMENT AND HABITS OF THE fOUNG. 1\ 
Leaving, then, out of consideration the color varieties as arrang 
by Dr. Fitch, we have a long-winged form, in which individuals from 
the eastern portion of the country differ from those found in the West 
by being more hairy and robust, as pointed out by Mr. Van Duzee; a 
short-winged form, found along the seacoast, and a similar inland form 
differing from this last chiefly in its more robust body, broader and 
usually much more abbreviated wings. 
DEVELOPMENT AND HABITS OF THE YOUNG. 
The newly hatched young are very active, and the first to appear 
may be observed with their progenitors about the bases of wheat, corn, 
or grass plants, and later all stages are seen mingling together, having 
little appearance of belonging to the same species, so greatly do they 
vary in size and color in their several stages of development. 
As a rule the bugs confine themselves to the lower portion of the 
plants attacked, but may later push their way upward, especially if 
the lower portion becomes tough and woody, finally covering it in 
patches, as seen in fig. 5. where they are shown on a stalk of young- 
corn. Mr. E. A. Schwarz relates a curious exception to this habit in 
Florida upon sand oats, Uniola paniculata, where the entire develop- 
ment of the insect is undergone upon the highest part of this tall 
plant and not close to the bottom. Mr. Schwarz has given as a proba- 
ble reason for this the fact that strong winds are continually blowing 
the tine, sharp sand through among the lower parts of the plants, 
rendering it nearly or quite impossible for the bugs to remain in that 
situation, thus forcing them to seek their sustenance farther up the 
plants. While the figure just referred to gives a good representation 
of the appearance of a corn plant when the chinch bugs are present in 
excessive numbers, yet the writer has invariably found that they much 
prefer a stalk that has been blown down by the wiud or partly broken 
off by the plow and left lying nearly flat upon the ground. 
In timothy meadows the very young are to be found only by pulling 
away the soil from about the bulbous roots and drawing down the dead 
sheaths that usually envelop them. An observer may even pull up a 
tuft of grass entire, and yet. unless he examines in this way closely. 
may overlook them, so snugly are they thus ensconced among the roots. 
If driven to forsake a tuft of grass the young bugs move t<> another 
and crawl downward, and are soon to be found as snugly settled as 
before. It is only when they are older and well advanced toward 
maturity that they work to any extent above ground, ami even then 
only in cases where they are present in great numbers. Singularly 
enough, where infested meadows are plowed up and planted with corn 
the females seem to forsake the young corn plants and select the occa 
sional stray clumps of timothy that cultivation has failed to destroy 
and deposit their eggs about these, so that later the young may be 
swarming about these last, while hardly one is to be found about the
