(9) We have also on hand, ready for publication, an illustrated 

 synopsis of one of the families of the Homoptera of Illinois (Jas- 

 sidse), by Mr. C. W. Wood worth, a former assistant in the office. 



(10) A monograph on one of the families of the parasitic 

 fungi of the State (Erysiphece), by Professor Burrill and Mr. F. 

 S. Earle, has been finished during the quarter a;nd is now in press 

 for the bulletin of the Laboratory. 



(11) Professor Burrill has also nearly ready for printing, re- 

 ports on two other families of Illinois fungi (Ustilagineas and Pero- 

 nosporeae). 



(12) The first volume of the zoological report, covering the 

 entire ornithology of the State, has been long in press, but makes 

 very slow progress, because two copies of the proof of the part now 

 printing must go successively to Washington. The four hundred 

 and thirty-second page has now been reached by the printer. 



The additions to the equipment of the Laboratory, made during 

 the last quarter, are not especially important, but are confined chiefly 

 to the usual increase of the library and to several pieces of the ap- 

 paratus of microscopy and bacteria culture. 



During the coming summer, besides carrying forward the econo- 

 mic work of the entomological office on the largest scale which our 

 resources will at all permit — giving especial prominence to field ex- 

 periment (a new feature of our work) — I hope also to make decided 

 progress in our knowledge of the aquatic life of the State — especially 

 in its lowest forms — and for that purpose expect to establish tem- 

 porarily a station on one of the lakes of northern Illinois, fully 

 equipped from the Laboratory for careful and thorough aquatic work. 



Beyond the customary routine action on the appropriations of 

 the Laboratory, I have no especial requests to make of the Board at 

 this meeting. 



Respectfully submitted. 



S. A. FORBES, Director of Laboratorv.
