crop for all townships in the State, and in collating and tabulating 

 this mass o£ information — a work which occupied the time of two 

 assistants for many weeks of the present summer and autumn. 



Under this head should also come the care of the entomological 

 breeding room by Mr. Hart, the preparation, determination, and ar- 

 rangement of the thousands of specimens collected, and the keeping 

 of the voluminous records, catalogues, and indexes of collections. 



PUBLICATIONS. 



Our regular publications run in four series, two from the Labo- 

 ratory and two from the Office of the State Entomologist, — the 

 former comprising the State zoological report and the bulletins of 

 the State Laboratory of Natural History, and the latter the biennial 

 entomological report and the bulletins of the entomological office. 



During the past two years we have finished the printing of the 

 first volume on the zoology of the State, — containing five hundred 

 and twenty pages of text and forty-six plates, — devoted to the orni- 

 thology of Illinois as far as the water birds. This is a reprint of the 

 volume, the first edition having been entirely destroyed in the burn- 

 ing of the office of the State Printer last February. 



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 Prof. T. J. Burrill and Mr. F. S. Earle, 

 (forty-five pages,) two papers by myself on the food and feeding 

 habits and structures of alimentation of the fishes of Illinois (one 

 hundred and five pages), one by Prof. H. Garman on the anatomy 

 and histology of a new genus of earthworm (thirty pages), one by 

 Mr. C. W, Woodworth on the classification of one of the families 

 of homopterous insects of the State (twenty-four pages), and two 

 papers on insect parasites by Mr. C. M. Weed, (fourteen pages). 



The entomological report for 1885-86 has lain unpublished to 

 the present time, caught in the general obstruction of the public 

 printing growing out of the State-printing controversy, but is un- 

 derstood to be now in press. 



As bulletins of the entomological office, we have issued an elabo- 

 rate report on the experiments of the years 1885-86 with arsenical 

 poisons for the codling moth in the apple orchard, an article on the 

 chinch bug outbreak, with 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.
