Illinois Horticultural Society of 1876. Many new species were found 
and have been described and much important matter obtained, but 
the work in this line being still incomplete from want of opportunity 
to study certain important species, and finding that the matenal on 
hand can not well be published in one report, this will be held over 
Another important object kept constantly in view during the past 
year has been the investigation of the insects injurious to coin, in 
fact this has been the chief field work of the season ; and although 
the number of new facts ascertained has not been as great as 1 had 
hoped, yet much useful information has been obtained, and much cor¬ 
roborative testimony in reference to what entomologists have hereto¬ 
fore published has been collected. A considerable portion of the re¬ 
port is therefore devoted to a description of the habits, history and 
characteristics of the species which injure this useful cereal, and to 
the suggestion of such remedies as are most likely to prove beneficial. 
In connection with this investigation Prof. French has made a special 
study of the various Cut-worms which often prove so injurious both in 
the field and garden; his paper on these insects is included chiefly in 
that part of the report relating to corn insects. As relating to the 
same subject. Miss Smith has made a somewhat special study of the 
Stalk-Borer (Gortyna nitela), which likewise proves injurious both to 
field and garden crops. She has also made a special study ot the 
Maple Bark-louse and Oak Tortnx. Her papers on these species will 
also appear in the present report. , . . 
The -Manual of Economic Entomology,” commenced in my toi-ner 
report, has been continued in this; the portion given here relating 
wholly to the Lepidtrptera or Butterflies and Moths, and has been pre¬ 
pared chieflv by Prof. French.. ^ , , , . - ., 
I have devoted considerable attention to the history of, and statistics 
in reference to, the Chinch-bug. What I have to present in reference 
to this species will be found in that part of the report relating to corn 
insects 
Miss'Middleton’s work, in part at least, will be apparent to those 
who see the insects already placed in the museum of the btate Agri¬ 
cultural Society at the capital. Nearly all of these specimens, as well 
as the much larger number not yet arranged, were prepared and 
spread by her. She has also assisted me in my microscopic observa¬ 
tions of the Aphides, and hasdiscovered and described several new spe-

A considerable time during the fall and winter has been devoted to 
determining species and arranging the collection for the Society s 
museum, in which work I have been assisted by Prof. French and Miss 
Middleton. Sixty boxes have been filled and are now arranged m the 
places prepared for them. These contain 1771 specimens belonging 
to 368 species, all of which (excepting about half-a-dozen species) are 
natives of Illinois. They have been arranged with reference to the 
kinds of plants they injure and their economic importance. 11 is the 
intention to make the wall display for popular use, showing our in 
jurious species and also the species that are beneficial in desvojing 
those that are injurious. We have endeavored to carry out tins in¬ 
tention so far as possible; and have therefore given the common 
names of the insects and the names of the plants injured, etc. In ad-
