YI 
LETTER OF TRANSMITTAL. 
Office of State Entomologist, 
Champaign, III., Dec. 21, 1892. 
To His Excellency , Joseph W. Eifer, Governor of the State of 
Illinois. 
Sir: I have the honor to transmit herewith my seventh re¬ 
port as State Entomologist of Illinois,—the eighteenth from this 
office,—applying to the years 1891 and 1892. 
I have had for some time the intention to present in my ento¬ 
mological reports a complete monograph of all insect injuries to 
Indian corn, to contain when completed not only an abstract 
of all published knowledge on the subject, but likewise all our 
own unpublished observations accumulated during the past ten 
years^. Believing that I could at present do the agriculture of 
this State no other service approaching this in value, I have 
prepared, as the greater part of this report, a first instalment 
of this treatise, consisting of a discussion of all insects injuring 
the planted seed and the roots of Indian corn. 
Respectfully submitted, 
S. A. Forbes, State Entomologist.
