Fifth Annual Report. 35 
examined to determine the relative number of bugs in various 
kinds of crops. 
Most of the fields along the route in which there was evi- 
dence that bugs were present, or had been present, were exam- 
ined, or if there were several such fields in any vicinity under 
similar conditions, one or more of them were examined to serve 
as types for the remainder. Besides, a number of fields were 
examined in which there were no signs of bugs. The quality 
of the soil, humidity of the soil, condition of crop, injury to 
crop by chinch-bugs, position of field in relation to other fields, 
hedges, ditches, etc., the relative number of living chinch-bugs, 
and the stages of development in which they were, and the 
presence and relative abundance of Sporotrichum and Empusa, 
were all noticed. Whenever possible, it was determined whether 
Sporotrichum had been introduced into the field examined dur- 
ing the season of 1895, or at any other time, and whether it had 
ever been introduced into a neighborhood or not. Also, the 
meteorological conditions prevailing during the time of the 
journey were noted, and the conditions which had prevailed in 
the different localities for some time previous were determined 
in many cases. . 
There had been flights of chinch-bugs in Douglas county at 
different times, late in June and early in July, before this trip 
was begun; and there were evidences in some cases that there 
had been a scattering of the bugs in localities along the route 
of the journey. Also, it is very probable that many bugs 
covered with Sporotrichum and Empusa had been washed away 
by heavy rains or made to disappear by other causes. This 
condition necessarily affected the relative abundance of living 
chinch-bugs in different localities at the time of examination, 
and the relative amount of bugs covered with Sporotrichum and 
Empusa as compared with the living. 
There were in all about 109 examinations made, a single ex- 
amination sometimes including several adjacent fields. In 
these examinations chinch-bugs living or dead were found in 
92 cases. In these 92 cases Sporotrichum was found in 80 
cases and abundantly found in 25 of the 80. Empusa was 
found in 58 cases in the 92, and abundantly in 15 eases. 
Twelve cases were noticed in which bugs covered with Empusa 
nearly equalled or exceeded those with Sporotrichum. In 36
