tories of insects, largely of economic species, made chiefly by Mr. 

 Hart and Mr. Weed. 



To this list r should perhaps add the routine work of the oflfice 

 in the collection of specimens, especially of insects, and in the label- 

 ing, deteruiinatioji, and arrangement of the insect collections which 

 have accumulated in the office, — a work which falls especially upon 

 Mr. Hart. 



Here I ought also to mention the studies made, at the expense 

 of the Laboratory appropriations, by Professor Burrill and his assist- 

 ant, on certain families of the parasitic fungi of the State, — a work 

 preliminary to the preparation of papers for our bulletins and the 

 final report on the cryptogamic botany of Illinois. 



The field work of the Laboratory and office has fallen chiefly to 

 myself and Mr. Weed. It has covered all parts of the State, from 

 Cairo to Galena, but has mostly been done in southern Illinois, where 

 the situation this year is of peculiar interest. The various trips 

 made since last March aggregate 2500 miles of travel. 



Our puhlicathnx comprise four series; the regular entomological 

 reports, the bulletins of the entomological office, the bulletins of the 

 State Laboratory of Natural History, and the State zoological report. 

 The papers and reports recently prepared and published, or now in 

 course of preparation, are as follows: 



(1) The 15th Report of the State Entomologist of Illinois, 

 now practically finished and awaiting the orders of the State Board 

 of Contracts. 



(2) A general account of the lake fauna of Illinois, delivered 

 as an address to the Peoria Scientific Association and published in 

 the Bulletin of that Association this year, and also in an emended 

 edition, as a separate 



(3) A general article on contagious insect disease read as a 

 |)residential address to the Entomological Club of Cambridge. Massa- 

 chusetts. 



(4) x\ special article on the same topic — the second of a series 

 — containing the results of our investigations and experiments on 

 this subject for the last two years. 



(5) An elaborate report on the experiments of last year with 

 arsenical poisons for the codling moth in the apple orchard, published 

 as a bulletin of the office. The first edition of five hundred copies 

 of this bulletin was soon exhausted and a second was issued. 



(()) We have likewise published and distributed widely two 

 general circulars on the chinch bug in southern Illinois. 



(7) I have also prepared two addresses to fanners" institutes — 

 on insects injurious to corn, and on apple insects— and have delivered 

 one or the other of these addresses at ei^rht farmers' institutes dur- 



... O 



ing the winter and spring. 



(8) A descriptive paper prepared by Mr. Weed, on certain 

 parasites of the insects of the apple orchard, is now in press as one 

 of the articles of the Laboratory bulletin.
