An account (p. 60) of precise experiments in laboratory and 
field with a fungous disease of the chinch-bug supposed to be due 
to Entomophthora, especial ly valuable as determining the effect of 
moisture upon the propagation of this disease. “The only way 
that this fuugoid disease seems capable of being employed in ag¬ 
riculture is by the establishment of some central propagating sta¬ 
tion to which farmers can apply and receive an abundant supply 
of infected bugs on short notice. By this means they could take 
advantage of a rainy period of a week or ten days, and, if they 
can contrive by sowing plats of millet and Hungarian to mass 
the bugs in certain localities about their fields, they might accom¬ 
plish something towards warding off an invasion. But the possi¬ 
bility of overcoming an invasion after it is fully under way, as is 
almost sure to be the case during a dry season, it must be con¬ 
fessed is not very encouraging.”

Mention of frequent occurrence of “fungus-killed larvae” in 
cages of wireworms. Death probably due to Metarrhizium an - 
isoplice.

in beehives.
