The utilization <»f iisli in tliis way is an old suggestion, and a very 

 practical (»n<^ under some circumstances. Many people sutler from the 

 mosquito plague when the insect breeds in a circumscribed and easily 

 accessible place, and where it could be destroyed by some such method 

 as that used by the level-headed Englishman. 



THE TRUE BUGS OR HETEROPTERA OF TENNESSEE.* 



No. 3 of Vol. IV of the Bulletins of the Tennessee Experiment Station 

 is devoted to the Heteroptera of that State, and in it Prof. Summers 

 has given an excellent series of keys to the families and genera of this 

 division of insects. In an introductory note he treats of the general 

 characters of the group, describes the structures mainly depended upon 

 in classification, and presents a figure in which these structures are 

 carefully exi^lained. 



The keys for the determination of the genera are models, and it is 

 only to be regretted that such families as the Capsidte, Lygseidfe, Coreidai 

 and Pentatomidje could not have been treated in the same manner, but 

 any one familiar with the Hemiptera can appreciate the difSculty of 

 ])resenting adequate keys in these families at present. 



The bulletin closes with a brief discussion of remedies to be used 

 against the Hemiptera and is naturally devoted to the preparation 

 and use of kerosene emulsion, which is recognized as of most general 

 use in the treatment of these suctorial insects. 



With the exception of a few oversights in proof-reading, leaving some 

 misspelled technical names, the typography is excellent, and the figures 

 will add much to the usefulness of the bulletin to the general public. 



The description of species would in many cases be insuflScient for 

 certain determination, but, for the purpose intended, the treatment of 

 the species mentioned is commendable. — Herbert Osborn. 



THE PHYLLOXERA IN FRANCE AND THE AMERICAN VINE. 



We have not before noted the encouraging Associated Press dispatch 

 published in our papers of last .summer concerning the relief which has 

 come to the vine-growing industry of France through the use of Amer- 

 ican stock upon which to graft the European vine. 



Pasteur says: "I have often heard our wine-growers praise the American vines." 



Senator Meinadier says: "My department, the Gard, was the first invaded by 

 the Phylloxera. We had 93,000 hectares of vineyard, of which only one-eighth 

 escaped. To-day we have about 1,000 hectares treated by snl)mersiou, about 1,000 

 by insecticides, and neai'ly 30,000 planted with American vines." 



Dr. Menudier, Vice President of the Department Phylloxera Committee, says : 

 "Since 1889 the territory in the Department of the Lower Charente covered with 

 American vines has nearly doubled." 



In the department of which Marseilles is the capital that region planted with 

 American vines equals that planted with French vines. A professor of agriculture
