ENTOMOLOGICAL RECORD.

Eecent notes on the Phylloxera from foreign sources. — 

 In November last, information was received from Henry Erni, United 

 States consul at Basle, Switzerland, that the Phylloxera vastatrix had 

 made its appearance near Geneva, and in December the following 

 letter was received, which is published in full : 



Referring you to my dispatch No. 95, about the appearance of the grape-root louse 

 at Pregney, near Geneva, the riddle received lately an important solution, for the 

 insect was discovered in the grape-houses of the Baron Rothschild, at his villa near 

 Geneva. It is proved that some of these grape-vines were imported from England, in 

 1869, where the disease occurred in grape-houses as early as 1863. From these facts the 

 origin of the grape-louse at Pregney appears obvious. 



At the meeting of the French Academy, on the 19th of October last, Professor Dumas 

 stated that two substances had now been discovered capable of destroying the Phyllox- 

 era : Ist, the sulpho-carbonate of potassa ; and 2d, coal-tar. Neither of these would 

 injure the gi'ape-plant. Experiments made on a large scale at Cognac and Montpelier, 

 France, hy delegates of the academy, were highly efficient. Both ingredients are cheap^ 

 for the x^rice of a kilogram of each does not exceed one franc. The sulpho-carbonate of 

 potassa is dissolved in water up to 37° Baum^, and 80 cubic centimeter (j§u liter) 

 poured upon every diseased grape-root. The best time is in November and March, 

 the ground at that time being moist and the insect sure to be in winter quarters. 

 The expense per vine amounts to about 10 centimes. Applying coal-tar, each root re- 

 ceives about 2 kilograms of this liquid, when it will penetrate the ground about 2 feet 

 deep. In both cases the grape-louse is effectually killed. 

 I am, sir, &c., 



H. ERNI, 

 United States Consul. 



We also give extracts from the report of the international congress 

 of vineyardists, at Montpelier, France, October 28, 1874, on the same sub- 

 ject, from the Journal d' Agriculture Pratique, No. 46 : 



The floor was taken by Mr. H. Mares, permanent secretary of the agricultural society 

 of Herault, and president of the ministerial commission. He commenced by recalling 

 to mind the experiments of 1872 and 1873, with the phylloxera, which were unsatisfac- 

 tory on account of the invasion of the " pyrale." In 1872 a new experimental field was 

 selected, near Montpelier, belonging M. Michel Termand. The experiments commenced 

 the 6th July, and comprise fifty-one methods, applied to squares of 25 vines each, the 

 squares being separated by two rows of untreated vines, left to serve as means of 

 comparison, and to prevent confusion in the effects of various modes of treatment. 

 One hundred and forty methods have since been tried in the same vineyard, of which 

 thirty-three were beneficial and nine injurious ; the others appeared to have no effect. 

 The most beneficial were as follows, the soil being chalky and ferruginous : Potassium 

 sulphate disolved in urine ; a mixture of the sulphurized manure of Berre, oolza cake, 

 and ferric sulphate ; potassium sulphate dissolved in water ; potash soap dissolved in 

 water; soot ; a mixture of farm-dung, wood-ashes, and ammonium hydrochlorate ; cow- 

 urine alone or with the addition of gas-tar. All the methods which have proved advan- 

 tageous are also mauurial, especially the salts of potash and ammonia. The injurious
