arsenic has served to keep them off the leaves but they go into the 
ground and attack the stalk. Squash bugs [Anasa tristis] are 
also abundant. Fourlinedleaf bug [Poecilocapsus lineatus |} 
is doing much damage to currants, specially to young plants. June 15. 
Wire worms have been very destructive the past two weeks to cabbage 
and cauliflower. No evidence of second brood of pear psylla or of the 
currant worm [Pteronus ribesii]. White arsenic has been more 
effective in spraying than paris green. July 1. The pear psylla has 
begun to appear. The first brood was very light, scarcely an adult to be 
found, but the dry weather has been favorable to the hatching of every 
egg. The trees have been sprayed with 8% of kerosene, but as the 
insects are covered each with a globule of honeydew, the insecticide is 
very ineffective. If dry weather continues, the pear crop will be ruined. 
July 5. Timely and heavy showers have done much to check the pear 
psylla; spraying with kerosene emulsion, 1 to 15, is more effective im- 
mediately after a rain. Apple aphis is persistent. Lady bugs very abun- 
dant. Fall web worm [Hyphantria cunea] is now working. 
July 14. Fall web worm begins to show its work on fruit and forest 
trees. Apple aphis is very persistent, injuring many trees. July 28. A 
few late caterpillars [possibly Clisiocampa disstria, though 
more likely Datana ministra or Schizura concinna] 
are found on the apple trees. Apple aphis still persistent. Aug. 12. 
Borers [probably Saperda candida] unusually numerous and 
active in apple and quince trees. Large numbers of eggs have been 
deposited and as many as 30 young larvae have been taken from a tree.

Delaware county (F. M. Simpson, Delhi)—Forest tent caterpillar 
[Clisiocampa disstria] in the sugar maples and causing much 
injury. They attack trees set out last year and completely defoliate them. 
Old trees suffer very much. The caterpillars begin in the upper branches 
and denude the limbs. Some trees have been protected by shaking the 
caterpillars from them and fair results have been obtained by spraying 
with paris green and water. May 25. Forest tent caterpillar still working 
havoc in this village and vicinity. June 2. I find that the groves of 
maples where the trees were partly defoliated by the forest tent cater- 
pillar are completely destitute of leaves, while the foliage is still green on 
trees that were not attacked. Sep. 30. 
Dutchess county (H. D. Lewis, Annandale)—Cold weather has 
somewhat checked insect activity, but even taking this into consideration,
