[Clisiocampa disstria]. June 2. Tent-caterpillars have ap- 

 peared in considerable numbers. June 8. Apple aphis [Aphis m a 1 i] 

 is very abundant on some trees, causing the leaves to curl. June 18. 



Schenectady county (Paul Roach, Quaker Street) — Tent-caterpillars 

 [Clisiocampa am e r i ca n a] are just hatching on the sunny. side of 

 the egg clusters. On the 8di they were active and feeding on the buds, 

 and that night we had a hail storm, and on the 9th it was cold and 

 windy, and they seemed dormant but hugged closer together. On the 

 night of the 9th ice one half inch thick was formed, and on the morning of 

 the'ioth the caterpillars were still alive, but they seem dormant, and, if 

 the cold spell lasts a few days, I think that many will starve to death. 

 Eggs of the white marked tussock moth [Notolophus leuco- 

 stigma] are quite numerous. May 10. The forest tent-caterpillar 

 [Clisiocampa disstria] has worked havoc in orchards here, 

 some being as bare as in midwinter. The appletrees suffered most, next 

 plum, pear and cherry. Forest trees are attacked in the order named : 

 ash, linden, elm, and maple. Some of the caterpillars died of a disease; 

 about May 25 the rest began to spin their cocoons. At this time a 

 cold storm came on, and but very few cocoons can be found. My 

 orchard and shade trees were sprayed with arsenate of lead, and, while 

 great clusters of worms can be found on the trees, the caterpillars have 

 eaten but little, some not at all. It is cheap, easy of application, efficient, 

 and with me has not burned the foliage of Japanese plums, the tenderest 

 of all. June 22. 



Schoharie county (J. F. Johnson, Breakabeen) — The appletree tent- 

 caterpillar [Clisiocampa a m e r i c a n a] is appearing in great numbers 

 this spring. I have also found many forest tent-caterpillars [Clisio- 

 campa disstria]. May 10. The cold and frost of last week has 

 checked the caterpillars. May 19. The forest tent-caterpillars are doing 

 very much damage. They are attacking the plum and other fruit trees. 

 May 25. Appletree bark louse [Mytilaspis pomorum] is very 

 thick on poplar and willow. There is now con.siderable variation in the 

 size of forest tent-caterpillars ; some are full-grown and others half the size. 

 June I. Forest tent-caterpillars are spinning their cocoons. They have 

 done a great deal of damage this year, stripping the foliage from many 

 trees and then attacking \ht new growth. July 26. The moths of 

 [Clisiocampa disstria] are appearing in great numbers. In a 

 place 5 miles square I think there are 500 acres of woods which have 

 been defoliated by the forest tent-caterpillars. July 13. A little black
