the corn much lodged and covered with chinch-bugs. About 
one hundred bugs dead with the white fungus, were scattered be¬ 
hind corn leaves, about forty rods from the place where the first 
infection material was introduced. 
September 19, Mr. Johnson carefully examined this field again. 
Corn had been cut, where it was worth saving at all, and shocked. 
The bugs were thickly concentrated in the shocks, but no traces 
of muscardine were seen among them. The insects were still very 
abundant in the stubble. The corn in many places was as flat on 
the ground as if a roller had gone over it, and in such places 
every stalk was blackened with bugs. A third lot of chinch bugs, 
about fifty in all, dead with Sporotrichum from the same source 
as the others (No. 68), were now scattered over the ground un¬ 
der the fallen corn, at one place about ten rods from the row 
where the second lot of bugs had been placed. The greater part 
of the corn on the ground was brown and dead, and there was a 
general movement of the chinch-bug hordes into late corn in an 
adjoining field on the west, and into a meadow touching the south¬ 
west corner. Considerable damage had been done by the insects 
to the grass in the latter field, and corn in the former was suffer¬ 
ing severely from their attacks. Not a single diseased bug was 
found in any of these fields at this time. 
Examined by Mr. Johnson September 26. Very few chinch- 
bugs in the stubble. One bug found imbedded in the white 
fungus. Many insects in the meadow. The late corn in the field 
adjoining the stubble badly damaged, the attack apparently in¬ 
creasing. No traces of disease seen in this field. Bugs seemingly 
vigorous and healthy. 
The final visit of the season to this locality was made by Mr. 
Johnson October 6. At this time the late corn in the field last 
mentioned in the preceding paragraph had been cut and shocked 
about a week, and the ground planted in wheat. The bugs had 
accumulated in enormous numbers in the shocks. Half a dozen 
fungus-covered insects were taken from shocks in this field at 
various places, and several were taken from grass in the adjoining 
meadow, where the chinch-bug attack was still spreading. A 
dozen or more whitened bodies were taken from shocks and under 
fallen corn in the field where the infection had been distributed, 
but the fungus was nowhere abundant, and long-continued search 
was required to find even a single specimen. A few live chinch- 
bugs, mostly adults and pupae, were still present in the stubble, 
and bugs in the same stages were quite abundant in the shocks. 
Corn in both these fields was a complete failure, and was 
saved for fodder only. Chinch-bugs dead with the white 
fungus were found in all fields examined in this county at this 
time, but only in two places (see Nos. 57 and 76) were they at all 
common, and even here the live bugs outnumbered the dead many 
thousand times. This experiment for the introduction and increase 
of the fungus by artificial means was to all appearance a complete 
failure.
