found to have been injured 20 per cent. Corn on high or low land 
seemed to be affected in about the same proportion. On Mr. Lewis’s 
place, one field was found in which over 50 per cent of the stalks were 
damaged, and upon the farm of a Mr. Taylor nearly every stalk in one 
field contained borers, and his yield was estimated to have been re- 
duced to from 6 to 8 barrels per acre to 2 barrels. 
Most of the larvee were found below the second joint. In one stalk, 
from which Mr. Cordley took 12 larve, they were arranged as follows: 
Seven below first joint, 1 between first and second, 3 between second 
and third, and 1 between third and sae In another stalk from which 
8 larve were taken, 1 was found \.. 
jn the tap root, 5 between first Phos 
and second joints, 1 between fifth 
and sixth joints, and 1 between 
eighth and ninth joints. 
Dr. J. S. Massey, of Comorn, 
King George County, Va., an in- 
telligent gentleman who has paid 
considerable attention to this in- 
sect the present season, informed 
Mr. Cordley that in his opiniow 
the territory embraced between 
the Rappahannock and Potomac 
rivers and extending from Fred- 
ericksburg to the Chesapeake 
Bay was pretty well infested by 
the borer, which first made its 
appearance in this section dur 
ing the season of 1890 on the 
farm of Senator Newton, of Co- 
morn. Subsequent to Mr. Cord. 
ley’s visit I made some effort to 
ascertain by correspondence and 
otherwise whether the insect

but was unable to hear of it in the vicinity of Colonial Beach, a sum- 
mer resort some 20 miles farther down the river, to which Washington 
steamers run daily. 
August 8, however, I visited this latter locality, and although in- 
dividuals about the resort were unable to give me any information, I was 
fortunate in finding the borer in the first cornfield which I visited. 
Large well-grown stalks of corn were infested only to a slight extent 
and then evidently only by large larve which had migrated from 
smaller stalks which had been killed some time previously. On the farm 
of Mr. J. S. Newton, of Maple Grove, Westmoreland County, some 6
