Some hitherto unnoticed publications of the Agricultural Experiment Sta- 

 tions.— Bulletin 10, of the Minnesota Station for March, 1890, contains 

 on article by Professor Lugger on "Oak Caterpillars," eight species 

 being mentioned, with an account of the life-history of each and two 

 original plates showing the larva and moth of each species. These in 

 the order of their importance are : Anisota senatoria, A. virgmiensis, 

 Datana minisfra, Edema albifrons, Janassa lignicolor, Perophora mels- 

 heimeri, Apatela brumosa, and Gastropaclia americana. The article 

 contains, besides the plates, five other original figures and presents 

 the matter in an admirable way. The same bulletin also contains an 

 article by Prof. Samuel B. Green on syringing with Loudon purple for 

 the Curculio on native plums, his experiment having proved very 

 satisfactory and showing that the crop of native plums can be as much 

 improved by the proper use of insecticides as any of the European 

 stock varieties. 



Bulletin 5 of the Oregon Station for April, 1890, gives a resume of 

 injurious insects by Prof. F. L. Washburn, the most important treated 

 being the Codling Moth, Woolly Apple-louse, Pear Slug, Peach Borer, 

 San Jose Scale, Flat-headed Apple-borer, Gooseberry Fruit-worm, 

 Currant-borer, Pea Weevil, Cut Worms, and Grain-beetles. Eemedies 

 are outlined and details of rather elaborate experiments given for rid- 

 ding granaries of Grsiin-beetles {Silvmius surinamensis). The article is 

 accompanied with many illustrations, and is followed by an article from 

 the same author on gophers and rabbits with remedies and poisons for 

 the same. 



Bulletin 9, of the Florida Station, for April, 1890, is entitled " Entomo- 

 logical Notes " by Dr. James C. Neal. He treats among others theKoot- 

 knot Worm, Cut Worms, Cotton Worm, Boll Worm, Cotton Stainer, 

 Leafy-legged Plant-bug, Orange Scale insects. Cabbage Butterfly, and a 

 number of insects injurious to forest trees. Formulae for spray solu- 

 tions and jjowders are published, and the bulletin closes with a notice 

 of certain insects not yet reported but which are liable at any time to 

 make their appearance in the State. 



Prof. A. J. Cook presents Bulletin 58, March, 1890, of the Michigan 

 Station, a rather full account of the leading substances used as insec- 

 ticides. The arsenites, kerosene emulsion and ointment, jiyrethrum, 

 carbolic acid emulsion, carbolized plaster, Bordeaux mixture, white helle- 

 bore, bisulphide of carbon, tobacco decoction and cyanogen are con- 

 sidered, and the bulletin will be of great use to the practical farmer and 

 grain dealer. Under a misapprehension, the author claims credit for 

 the first use of kerosene emulsion. The true status of this claim was 

 shown at the late meeting at Champaign, the proceedings of which are 

 published in this number. 



Prof. John B. Smith has published a two-page bulletin, giving two 

 spray solutions to be used against the Wheat Aphis in cases of extreme
