age done but to prevent any 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 Scymnid beetle. Pentilia 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 part of May to 
Prof. C. W. Wood worth 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 Brunsivick, 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 
shown me and I said it was a scale, and that kerosene 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 perniciosus. My lack 
of familiarity with scale insects prevented my recognizing the species 
atftlie time, and the lack of further complaint or incpiiry 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
