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 Midge, and brings together all of the earlier references to the 
appearance, spread, and depredations of this species 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 larve, 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 from this country 
to take a position 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 pump 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. 
A Bulletin from New Mexico.t—Mr. Townsend treats, in his first bulle- 
tin as entomologist of the New Mexico Agricultural College Experi- 
ment Station, of some of the insects injurious to fruits in that Territory. 
The insects treated are the Grape Leaf-hopper, the Grapevine Flea- 
beetle, The Codling Moth, the Oyster-shell Bark-louse, the Woolly Root 
Aphis of the Apple, the Scurfy Bark-louse, the Apple-tree Tent-cater-
