eradicate this species from any field. First by proper rotation of 
crops, second by thorough fall plowing and turning under, in the fall, 
some good strong lime. Where this plan has been adopted the re¬ 
sult has been favorable. 
The chinch-bugs appealed in limited numbers in some localities, in 
the fall, and there are some grounds to fear that if next season is dry 
they may develop to such a degree as to do considerable injury. 
This species has been selected by the National Entomological Com¬ 
mission as one of those to be investigated by that body. In compli¬ 
ance with the request of the Commission, I prepared the manuscript 
of a Bulletin to be issued under the Department of the Interior; as 
soon as published I will request a somewhat thorough distribution 
throughout our State. If a list of names were furnished me by your 
Secretary they could then be distributed directly from the Interior De¬ 
partment, as that Department would willingly do so if requested and 
a list of names furnished. 
'I am inclined to the belief that as a means of counteracting this 
destructive pest, it would be advantagous to push the cultivation of 
winter wheat as far northward as this can be done with satisfactory 
-results, as a careful examination of the statistics of losses shows that 
this variety suffers less from the attacks of this insect than spring wheat. 
Considerable complaint reached me early in the spring, and 
also late in the fall, in reference to the Hessian fly. In some cases 
specimens sent proved to be this species, but in other cases where 
I caused fields to be examined, supposed to be injured by this fly, no 
specimens could be found. I am therefore inclined to believe from 
evidence furnished that the injury to the fall wheat was caused part¬ 
ly by the wheat aphis though chiefly by the fly. 
• Complaint from some sections of the State has been received that 
a new worm has been injuring the clover. So far I have been unable 
to procure specimens of this worm and hence am unable to determine 
what it is. 
Having been repeatedly called upon during the past two or three 
years to give information in reference to the parasites infesting domestic 
animals I have concluded to devote a part of the present report to 
that subject, although it requires me to travel out of my legitimate 
field. As the investigation of the history of internal parasites re¬ 
quires a long study of the species, I have necessarily been compelled 
to have recourse to the works of others on this subject. 
It is my intention to prepare as soon as possible a list of useful 
plants and other substances injured by insects with the names of the 
species, as a means of ready reference. Whether I will be able’to 
complete it before this report is printed so as to insert it is doubtful. 
Since my former report was issued fourteen drawers of the insect 
cabinet have been filled with properly arranged and classified speci¬ 
mens. This part of the work is necessarily slow but as fast as the 
specimens can be obtained, after they have been carefully examined 
and determined, they will be placed in the museum of the Depart¬ 
ment. A drawer nearly filled is sometimes retained for months wait-* 
ing until a specimen required to fill out the series can be obtained. 
I expect during the coming year to send in the coleoptera, some of 
which have been awaiting determination. 
As ascertaining of habits and life-history of species, and the best 
means of destroying or otherwise counteracting the injurious ones is
