General notes and results of the observations and experiments 
of 1892; laboratory notes, reports of Field Agents, and forty-page 
list of field experimenters in Kansas who have made report. Di¬ 
rections for obtaining and supplying the- chinch-bug infection are 
given as an appendix.

Says that the fungoid and bacterial parasites of the chinch-bug 
“will be found available during some seasons and within a cer¬ 
tain limit,” there being a possibility of rendering them locally 
and temporarily more effective by persistent artificial cultivation 
and distribution. The irregularity of outbreaks a feature which 
prevents the ordinary farmer from using means of protection. 
Small plats of millet or Hungarian grass are suggested as lures 
for the deposit of eggs, since they would facilitate the use of 
vegetal diseases, the insects being here better controlled than in 
the fields of ordinary cultivation. Corn fields said to be next in 
value, as the young must there, of necessity, congregate in com¬ 
pact masses. Should be gome central station for the supply of in¬ 
fection material.

Cincinnati Soc. Nat. Hist., v. 15, p. 173; also printed as 
separate.) 
Popular account of casual observations in Ohio of what was supposed 
to be Empusa mu&cce infecting flies outdoors, and mention of 
the almost total extermination of Phyionomus punctatus by Empusa 
sphcerosperma. Note of Empusa pachyrrhince (named provision¬ 
ally) infesting a species of Pachyrrhina; and of Empusa aulicce 
attacking the fall brood of larvae of Spilosoma virginica under 
circumstances that insure wide dissemination of the disease, the 
method of infection also being discussed. As an illustration of the 
rate of development of the hypha of germination, the effect of an 
Empusa upon Diedrocephala mollipes is mentioned. The use of 
the name Empusa generically in entomology is said to have priority 
over its botanical use.
