injury to grain and manufactured products in elevators and 
mills. An elaborate article by Mr. Johnson is now ready for the 
press, on the Mediterranean Flour Moth—a pest somewhat 
recently introduced into America, which has proven elsewhere 
capable of enormous and almost uncontrollable mischief in flour- 
ing mills. 
PUBLICATIONS. 
The final preparation for the press of my biennial entomo- 
logical report for 18gr and 1892 was delayed by Exposition 
engagements and by other circumstances beyond my control. 
It is, however, now in the hands of the printer, and the report 
for 1893 and 1894 is far advanced towards completion. It will 
doubtless be ready for the press at the usual date. The same 
circumstances have delayed the publication of the second volume 
of the series of final reports on the zodlogy of the State, that con- 
cluding Mr. Ridgway’s contribution to the ornithology of IIli- 
nois. It now awaits only the copying of certain plates, the 
originals of which were destroyed by fire in Springfield. 
Additional papers, either prepared by the Laboratory force 
and printed elsewhere, or published in our Bulletin since my 
last report, are as follows: by the Director of the Laboratory, 
‘“‘A Preliminary Report on the Aquatic Invertebrate Fauna of 
the Yellowstone National Park, Wyoming, and of the Flathead 
Region of Montana,” ‘‘The Progress of Economic Entomology 
during the Years 1891 and 18g2,’’a ‘‘Presidential Address,” read 
before the American Association of Economic Entomologists, 
August 14, 1893, and ‘‘Report of the Director of the Aquarium 
of the United States Fish Commission at the World’s Colum- 
bian Exposition;” by Prof. H. Garman, ‘‘A Synopsis of the 
Reptiles and Amphibians of [Illinois;” by Dr. F. W. Goding, 
“Bibliographical and Synonymical Catalogue of the Described 
Membracidz of North America;” by Prof. G. H. French, ‘‘De- 
scription of two New Deltoid Moths;” by Mr. W. E. Loucks, 
“‘The Life History and Distribution of the Prothonotary Warbler 
in Illinois;” and, by Prof. C. W. Rolfe, ‘‘List of Altitudes in the 
State of Illinois.” 
REMOVAL OF LABORATORY.
