places near the bottom of the barrel a lighted lantern. In- 

 sects of all kinds are attracted by the light, and in flying 

 around it they strike against the sides of the barrel, when 

 their wings are gummed, and they fall to the bottom. These 

 may then be thrown into boiling water or otherwise destroy- 

 ed, and they can, indeed, be made to serve a useful purpose 

 as a manure. If a similar method of destroying the moth 

 of the canker-worm, which is so fatal to the apple crop in 

 New England, can be successfully applied, it will prove 

 much more simple, as well as more effectual, than any reme- 

 dy hitherto employed. 3 B, April 2, 1874, 611. 



SULPHIDE OF CARBOX FOR PHYLLOXERA. 



Among other remedies lately suggested for the destruction 

 of the terrible Phylloxera, or grape-vine louse, is that of M. 

 Monesteux, in the application of sulphide of carbon. Two 

 or three holes are to be made by means of an iron bar at 

 the root of the vine, and one or two ounces of the liquid 

 placed in each, the holes being then filled from above with 

 earth. The odor of the sulphide penetrates to the roots and 

 affects the plant above, and, according to the writer, brings 

 about the destruction of every insect in the course of a w r eek 

 or ten days, without injury to the vine. The remedy needs 

 to be tested by long-continued trial, as the insect is one that 

 it is extremely difficult to exterminate by any treatment.

THE PHYLLOXERA AND ITS PARASITES. 



M. Planchon, who was sent to America some months ago 

 by the government of France for the purpose of investigat- 

 ing the natural history of the Phylloxera, ov grape-vine louse, 

 in the country believed to be its native home, and from which 

 it was transplanted to Europe, has recently reported the re- 

 sults of his inquiries to the Academy of Sciences of Paris. 

 While here he spent much time with Mr. Charles V. Riley, 

 the State Entomologist of Missouri, to whom we owe a en-cat 

 deal of our knowledge of this destructive insect. Plan- 

 chon communicates to the Academy what he considers three 

 important observations; first,"the absolute certainty that the 

 American Phylloxera is the same insect, specifically, as that 

 which destroys the vines in Europe ; second, that certain
