A dozen or more insects dead with Sporotrichum were found 
in a corn field belonging to Mr. Win. Kelley, one mile east of the 
Heth farm, and several were taken from the surface of the ground 
under stools of foxtail-graes along the roadside in the immediate 
vicinity of the same field. 
The Heth farm, as well as the surrounding country, was again 
examined by Mr. Johnson and myself October 10. The fungous 
attack had not increased in intensity, so far as could be ascer¬ 
tained, in the meadows F and G, but the chinch-bugs had con¬ 
tinued their ravages, and the irregular line marking the boundary 
between the infested area and the remainder of F and G had 
moved several feet eastward. The whitened bodies of dead bugs 
could be easily found on the ground by parting the grass at any 
place west of the division line, and they were quite abundant under 
leaves and rubbish in the sorghum stubble E, but the growth in 
this latter place had the characteristic weathered appearance of 
over-ripeness. In corn D an occasional trace of the fungus could 
be seen, and several chinch-bugs imbedded in it were found under 
stools of grass along the roadside between C and D. In corn B 
the fungus was found in shocks and in the open field in the 
stubble, but that from the surface of the ground under the shocks 
was of a much more recent growth than that taken from the open 
field. An occasional bug dead with this disease occurred on the 
ground in the uncut corn in the same field. 
One mile east, on the Kelley farm, to which reference has been 
made, cliinch-bugs enveloped in the white fungus were found in 
corn on the ground in low, damp places, under fallen leaves, 
weeds, grasses, and other rubbish. They were also quite abundant 
along the roadside under stools of grass, but on the whole the 
fungus was not so plentiful as twelve days previous, and the 
growth was comparatively old. In an adjoining w T heat field, a con¬ 
siderable number of dead insects were found attached to the 
blades of young wheat plants, and on the ground between the 
drill rows. After counting both live and dead chinch-bugs on a 
given area, it was estimated that about twenty-eight per cent, 
were dead. Subsequent examination of collected specimens showed, 
however, that the destructive agent in this instance was the gray 
muscardine (Eniomophthora aphidis ); but a few dead chinch- 
bugs from this field, showing no external trace of a fungous 
growth, developed a profuse growth of the white muscardine 
when placed on damp sand. This fungus was also fouud on 
chinch-bugs in all corn fields examined at this time for a distance 
of four miles south of the Heth farm, but was nowhere as abundant 
as on the latter place. 
It has been already reported on pnge 118 that the white fungus 
of the chinch-bug was very widely distributed throughout adjoin¬ 
ing counties at this date, and the general tenor of our observa¬ 
tions at this time supports the hypothesis that the Heth outbreak 
was a spontaneous one, arising under the influence of especially 
favorable conditions, which were substantially as follows: (1) an 
abundance of food—wheat, corn, sorghum, and grass, into which
