KEPOKT OF STATE LABORATORY OF NATURAL HISTORY.

191

As bulletins of the State Laboratory of Natural History, we have issued an article on one of the families of parasitic fungi of the State (Erysiphese) by Professor T. J. Burrill and Mr. R S. Earle (45 pages); two papers by myself on the food and feeding habits and structures of alimentation of the fishes of Illinois (105 pages); one by Professor W. H. Garman on the anatomy and histology of a new genus of earthworm (30 pages); one by Mr. C. W. Woodworth on the classification of one of the families of homopterous insects of the State (24 pages); and two papers on insect parasites by Mr. C. M. Weed (14 pages). The entomological report for 1885-86 has been unpublished to the present time, caught in the general obstruction of the public printing growing out of the State printing controversy, but is understood to be now in press. As bulletins of the entomological office, we have issued an elaborate report on the experiments of the years 1885-86 with arsenical poisons for the codling moth in the apple orchardman article on the chinch-bug outbreak, with economic recommendations for its control; and an article on the life history of the Hessian fly, setting forth the results of our field experiments on the subject. We have also issued several entomological circulars not of any series. Articles written at the Laboratory but published elsewhere include a paper on the present state of our knowledge concerning contagious insect diseases, prepared as a presidential address for the Entomological Club of Cambridge, Massachusetts, and published in "Psyche," the organ of the club; a paper on the food of the fishes of the Mississippi Valley, read at the 17th annual meeting of the American Fisheries Society in Detroit, Michigan, and published in their "Transactions" and also as a separate pamphlet; a paper on the relations of wTheat culture to chinch-bug injury, read at the Cleveland meeting of the Society for the Promotion of Agricultural Science, and published in their "Proceedings;" four papers for the State Horticultural Society by myself and Mr. Weed, printed in the annual volume of the Society; three technical entomological articles by Mr. Weed and two by myself, printed in "Psyche" and in Eniomolocjica Americana; and a considerable number of articles written for the agricultural papers in response to inquiries from their editors. Here also should be mentioned an article by Professor Burrill giving the results of his study of the broom-corn disease already referred to, this paper being published in the Proceedings of the Society of American Microscopists for 1887.
