at any time during the winter with kerosene emulsion diluted from 7 
to 9 times will, it is believed, reach and destroy many of the insects, 
and will be more effective if the loose bark be scraped from the trunk 
and larger limbs before the application be made. 
Mr. Davis wanted to know the authority for the occurrence of the 
species in Michigan, and was informed that it was reported by Mr. 
Schwarz. 
Mr. Southwick reported a case of extraordinary abundance near Xew 
Baltimore, X. Y.. in 1893, which was followed by almost total disap- 
pearance the present season. 
Dr. Lintner referred to a case reported by him of a similar excessive 
abundance with total disappearance'the year following in the Hudson 
Kiver valley; but said that the insect had again appeared this year. 
He referred to the experiments by Mr. Slingerland, indicating that pure 
kerosene was effective in destroying the eggs of the Psylla, and stated 
in the same connection that he had applied undiluted kerosene to plum 
and rose in full leaf without material injury. 
Mr. Marlatt said that from his experience it seemed probable that 
the reports of failure to destroy the eggs with very strong mixtures had 
been due to the fact that the observations had not been continued long 
enough : and by referring to his experiments he showed that the eggs 
retained for a long time after treatment every appearance of life, but 
eventually, with the strongest washes, shriveled and died in large per- 
centage. In answer to questions by Mr. Ashmead. he also stated that 
no true parasites had been reared from any stages of the Psylla. 
Mr. Smith, said he would defer his discussion of this paper until his 
own, which included the same subject, was read. This paper followed. 
NOTES OF THE YEAR IN NEW JERSEY. 
By John B. Smith, New Brunswick, X. J. 
Although it is early in the season for a review of its insects, yet my 
experience has been that practically most of the damage to crops in 
our State is done before the middle of August; and that after that 
time insect life, or at least that portion of it which preys upon culti- 
vated plants, is on the decline. In our State the season has been an 
extremely interesting one from the insect standpoint, and it has been 
at the same time the most destructive within my experience. So many 
troubles made their appearance that I found it desirable to spend in 
actual field work between forty and fifty days between April 30 and 
August 10. 
In the first place, the San Jose scale forced itself upon my atten- 
tion, and it occupied a large portion of my time in following out its
