within the costa behind them, one behind the other, and a small spot 

 ■opposite the space between them, beneath the fold ; the portion of the 

 wing from the basal fourth to the end of the disc, included between the 

 -costa and the fold, is suffused with bluish fuscous scales, each of which 

 under the microscope appears tipped with hoary, and the extreme costa is 

 black; the wing beneath the fold is whitish ; just before the middle is a 

 lunate streak of dark brown raised scales, extending from the dorsal 

 margin to the fold, and margined with white in the concavity behind ; at 

 the end of the disc are two other larger tufts of bluish brown raised 

 scales, margined before by yellow ochreous, and opposite to them is a 

 long, narrow, very oblique white costal streak, margined behind by a 

 narrow, dark brown line, which separates it from a somewhat wider yellow 

 ochreous streak, containing three small white costal streaks or spots ; 

 behind the tufts the wing is ochreous, streaked with fuscous. Al. ex. %

RECENT NOTES ON THE PHYLLOXERA FROM FOREIGN 



SOURCES.

 REPORT OF THE U. S. DEPARTMENT OF AGRICULTURE.] 



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 :

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

 Professor Dumas stated that two substances had now been discovered
