ENTOMOLOGICAL SOCIETY OF ONTARIO. 63 



In connection with the agricultural exhibits of some of the States were several 

 collections of insects. Minnesota showed specimens of Coleoptera, Lepidoptera, the bee 

 moth, and injurious locusts, all well mounted and arranged. Several colleges and schools 

 also made exhibits. The most important of these was that made by the Illinois State 

 Laboratory of Natural History, under the direction of Prof. S. A. Forbes. This was a 

 most instructive, well arranged and well prepared display. It illustrated the methods of 

 work and lines of study pursued. Fronting on the main aisle was an office fitted for entomo- 

 logical work, such as might be occupied hy an entomologist and two assistants, one for 

 office and one for field work, and an amanuensis, showing arrangement of tables and cases, 

 all supplied with the necessary apparatus and I'eagents. Examples of the library, library 

 catalogue, collections of all classes of material, records with their indexes and methods of 

 keeping notes, also appeared here. A fall set of the publications of the State laboratory 

 and State entomologist's office were here displayed. The size of this room was twenty 

 by twenty-seven feet. At the back of this office was a small section of an insectary, fitted 

 with breeding cages for all kinds of insect life, sand tables, various insectary supplies and 

 apparatus for experimentation and study in the contagious diseases of insects. This 

 measured eleven by twenty feet. On the outside of the enclosure just described, and in 

 adjoining cases are ranged the collections illustrating the v-irious lines of work pursued at 

 the State laboratory. The economic work is represented by four collections, one shows 

 the insects injurious to the apple in all stages as far as obtainable, to the number of 1 76 

 species. It may be mentioned en passant that Dr. Lintner has now on record the names 

 of 282 species of insects injurious to the apple. The second collection showed the 

 injurious insects of corn in the same way, numbering 149 species; the third, those of 

 wheat, fifty-seven in number, and the fourth, those of the strawberry plant, fifty species. 

 The more minute forms are accompanied by exquisite water colour sketches, the work of 

 the laboratory artist. Miss Lydia M. Hart, showing their appearance when magnified. 

 The boxes are fifteen and a quarter by eighteen inches, and two and a half deep within. The 

 front and back of glass, the sides of wood separable into two halves along the middle of 

 the sides. The back is lined with sheet cork attached to the glass by a wax mixture, 

 the cork covered with paper of neutral olive' tint, which greatly enhances the app"arance 

 of the specimens. Half-sized boxes are used where the space requires it. Studies on the 

 foods of auimals were represented by three collections A most remarkable exhibit 

 which drew much attention was that of the average food o? a robin during the part of the 

 year that that bird is in Illinois, as determined by percentages obtained from the study of 

 1 1 4 stomachs of these birds taken at all times and seasons The quantity as well as the kind 

 of each element is shown, and illustrates well th ; difficulty which sometimes meets one 

 in determining whether a certain bird or animal should be considered beneficial or 

 injarious. Elaven full-sized boxes are used ; theycontaia 5,481 pinned specimens and 111 

 tubes of alcoholic material, mostly eighteen inches long, which is the full length of the 

 box. Eleven of these tubes exhibit the vegetable elements of the food. A collection of 

 insects found in the food of birds contains 195 species, and one of those found in the food 

 of fishes includes ninety-one species The insect fauna of the State is illustrated in two 

 c;;llections, the common insects of the State numbering 1,578 species, occupying sixty-nine 

 cases. In nine boxes is shown the geographical distribution of the commoner Illinois 

 butterflies, those occurring throughout the State, those peculiar to Southern, Central and 

 Northern Illinois ; those found also in Europe, in the Atlantic States, and in the Pacific 

 States are separately grouped. AcoUectioa of 459 species of pinned insects is exhibited, 

 which is one of forty collections lately made and distributed to high schools of Illinois 

 which were in need of them. 



Several collections of more or less interest were exhibited from foreign countries. 

 Most of these were unnamed, consequently of no value for reference. Russia and Germany 

 showed grand collections of forest insects. Canada was represented by a collection of 

 al)Out twenty cases prepared by myself, with the assistance of several members of the 

 Entomological Society of Ontario, who kindly contributed specimens. The moths, filling 

 eight cases, were arranged by Mr. J. Alston Moff it, and two c:ises of Hymenoptera by 

 Mr. W. Hague Harrington. The collection of Diurnal Lepidoptera was probably one of
