316 UNIVERSITY OF ILLINOIS. number of collections, including under this head each object or lot of objects specially numbered and separately entered on our notes or in the accessions 7 catalogue of the Station, is thus nearly 12,000. Besides these, mention should be made of about 400 microscopical slides of serial sections of oligocha?te worms made for Professor Smith in the course of his studies of that group. LIST OF COLLECTIONS. Shallow-water collections with Birge net Qualitative collections with surface net Quantitative collections with plankton apparatus. Protozoa and Rotif era collections Vermes " Crustacea '.' Arachnida " Insecta (liquid collections) Insecta (pinned specimens) Mollusca collections Fishes..

It has been thus far the primary object of the entomological studies made by Mr. Hart to make us fully acquainted with each species in all its stages as a preliminary to investigations along other lines. To this end extensive search has been made of all varieties of situation in the waters of the Station field, the species at each location being listed at each visit, and collections being also made. The regular typical localities represented by the substations have been further searched at regular intervals for two years. About five hundred lists and illustrative collections have thus been accumulated. The biological observations and breeding-cage experiments made during this time are recorded on some seven hundred note slips. The Hymenoptera and a large part of the Diptera and Lepidoptera have been worked up, and reported upon in a paper on the entomology of the Illinois river and adjacent waters, published as Article VI. of Volume IV. of the Bulletin of the State Laboratory of Natural History. Since this publication r much additional information concerning these groups has been acquired. Careful studies have been made on some of the smaller Diptera, on the waterbeetles, and upon the Neuroptera, Thysanura, and Hydrachnidae. The dragonfly collections have been determined by Mr. J. G. Needham, formerly Instructor at Knox College, and by Mr. C. C. Adams, an assistant in the State Laboratory. These entomological collections represent some 350 species of insects. Every effort has been made to identify, by breeding, eggs, larva?, and pupa? of insects aquatic in any stage. About 275 hitherto undescribed forms have thus been obtained, and immature stages of about 225 species have been accurately identified.
