For more than a year this fungus affection was not again 
und among chinch bugs, although a close watch was kept for 
, but August 7, 1888, it was seen at Flora, in Clay county, 
stening dead bugs to leaves of corn. On the 24th of August, 
: Albion, in Edwards county, it was next observed. Here, 
lys Mr. Marten's field note, “the bugs had died by wholesale, 
te ground under the corn being freely sprinkled with their 
hitened bodies, both in the standing corn and in the stubble." 
hey were also quite numerous behind the sheaths of the leaves, 
n one lump of earth with a measured surface of two square 
ches, twenty-six fungus-covered bugs were counted, and it was 
timated that chinch bugs were less than a third as numerous 
this entire neighborhood as a month before. October 18 the 
sease was still prevalent at Flora and Nashville, as shown by 
♦ecimens collected at that time, and again at the former place 
3cember 18 of the same year. It also appeared repeatedly at 
te office among living specimens brought in from the field and 
>pt under favorable conditions. One lot, for example, obtained 
3 Ashley, Washington county, September 18, provided with 
od in a pot of earth covered by a bell jar, died, to the. last 
le, with this fungus disease. 
Specimens obtained from Minnesota, through the kindness of 
rofessor Lugger, during the latter part of October, 1888, 
towed the presence of the Sporotrichum a few days later, and 
ovember 1 began to die. As it was at this time abundant at 
te office in other lots of chinch bugs, it is quite likely that 
ese Minnesota bugs became infected after their arrival. This 
t continued to die in a similar manner until December 18, 
hen the last disappeared. It was not noticed by us upon any 
her insects that year excepting specimens of Parandra brun- 
J a found dead in the woods November 1 and 5. 
This fungus appeared next with us May 11,1891, in a collection 
specimens of Disonycha pennsvlvanica, kept on a varnished 
Lie in the dry air of my office, under a large, high bell iar, 
here they were supplied abundantly with food. A large num- 
ir of these beetles (collected for an observation of their breed- 
g habits) died with it here. 
During the spring of 1891 it has occurred occasionally in field 
Elections, and I have also received it from Professor Snow, of 
ansas, (in May, 1891) on examples of chinch bugs collected 
Chautauqua county, Kansas, where they were reported to be 
ring bv thousands.
