The "Wheat Midge in Ohio.*— In a recent bulletin of the Ohio Agricul- 

 tural Experiment Station our agent, Mr, F. M. Webster, treats of the 

 Wheat ]\[i(lge, and brings together all of the earlier references to the 

 api»earauce, spread, and dei)r<Mlations of this s[)ecies within the State 

 of Ohio. He republishes Fitch's figures of the insect and summarizes 

 the life history, recommending as the only thoroughly practical pre- 

 ventive the deep plowing of the wheat stubble in the fall, thereby 

 covering the insects so deep in the earth that they are unable to reach 

 the surface in the spring. This should be done as soon as possible after 

 harvest. The burning of the stubble before plowing is also recom- 

 mended, and a rotation of crops is said to add to the efficacy of the 

 plowing. The author has found larvte, which he thinks belong to this 

 species, under the sheaths of young plants. He has also reared the 

 adults from the heads of, rye in July and from volunteer wheat from 

 September 1 to November 3. 



Injurious Insects in Queensland. — We have just received Bulletin No. 10 

 of the Department of Agriculture of Queensland, which is a report of 

 several agricultural conferences held in Queensland during 1891. One 

 of the papers published in this bulletin is an abstract of an address 

 given by Prof. E. M. Shelton, who recently went out fi'om this country 

 to take a i)osition in Queensland. His address dealt with the subject 

 of insect pests, and was an admirable summary of some of the general 

 facts connected with economic entomology. He spoke particularly of 

 the arsenical sprays and the use of kerosene emulsion, and exhibited a 

 spray jiump and cyclone nozzle, showing the character of the spray. 

 He recommended the bisulphide of carbon for grain weevils, and an- 

 nounced the fact that he was experimenting with kainit as a fertilizer 

 and as a remedy for underground insects. His remarks were received 

 with much interest, and the agriculturists of Queensland are evidently 

 very much alive to the necessity for work against injurious insects.
