age done but to prevent auy similar future occurrences. I have not 

 learned that the other firm has taken any such measures, but I do 

 know that a lawsuit has been instituted against this second firm, and 

 the probabilities are that this action will accomplish what mere qualms 

 of conscience might fail to bring about. The result of the whole 

 experience, it seems to me, can not fail to make all nurserymen 

 extremely careful in future; and care in regard to injurious insects is a 

 quality in which some of them have been greatly lacking in the past. 

 In this paper I have given simply the results of the investigation of 

 infested localities and of the remedial measures carried on. Careful 

 investigations of all of the other points necessary to a complete mono- 

 graph of the species from the economic standpoint are under way, and 

 it is hoped that the material will be in such shape by the close of the 

 season that a special bulletin of considerable length may be published. 

 One other interesting point may be mentioned before closing, and that 

 is, that a little Scymuid beetle, PentiUa misella, which was found by 

 Mr. Schwarz last September in such numbers at Charlottesville feeding 

 upon the scale, has also been found in other eastern localities, and that 

 an attempt has been made to introduce it into California, since it does 

 not normally occur in the west coast fauna. A considerable number of 

 living and healthy specimens were sent in the latter i^art of May to 

 Prof. C. W. Woodworth at Berkeley, who wrote that the insects were 

 received in good condition and had been placed upon a well-infested 

 peach tree at Oakland, where they would be kept under observation. 



The next paper on the program being on the same subject, discussion 

 was deferred. Mr. Smith then read the following: 



THE SAN JOSE SCALE IN NEW JERSEY. 



By John B. Smith, Xew Brnnstvick, X. J. 



In March, 1892, the agriculturist of the station received from a nur- 

 sery in our State a pear twig, with a card inquiring whether the insect 

 on it was an aphis, a scale, or the pear ''Scilla." It was in due time 

 sliown me and I said it was a scale, and that kerovsene emulsion should 

 be used. I presume that this message reached the sender and was 

 considered satisfactory, for I heard nothing more concerning it. The 

 twig was labeled, placed away, and forgotten; recently it turned up 

 again and proves to be infested by the Aspidiotus pefniciosus. My lack 

 of familiarity with scale insects prevented my recognizing the species 

 at the time, and the lack of further complaint or inquiry disposed me 

 to believe that it did not amount to anything. Had I been familiar 

 enough with scales to recognize the importance of the specimens then 

 in my hands, a portion of its spread could have been prevented. In
