Putnam Station [Washington county]. May 19. The larger forest tent- 

 caterpillars are about one third grown [at Putnam Station], and it looks 

 as if they would be very numerous this season. 



Delaware county (F. M. Simpson, Delhi)— A trip through several 

 groves shows that very few forest tent-caterpillars [Clisiocampa 

 d is stria] are present, the cold of the past few days possibly having 

 some effect. May 15. An examination of five maple groves leads me 

 to believe that the caterpillars are the worse for the cold weather, as there 

 were many dead ones among the leaves. Branches with the remains of 

 the web on the surface or in the axil had no caterpillars or else dead 

 ones. Unfortunately some of the eggs had not hatched before the cold 

 weather, and they threaten considerable damage, specially in valleys 

 where the sun does not strike and vegetation and other life is more back- 

 ward. Others in this vicinity think that the cold has checked and possibly 

 destroyed a large proportion of the caterpillars. Groves that were en- 

 tirely denuded last year are putting forth leaves this spring on about one 

 half of the branches. Many of the twigs are dead, and adventitious buds 

 are springing from the sides of the branches. Many individual trees are 

 entirely dead. May 18. 



Dutchess county (H. D. Lewis, Annandale)— The warm weather of 

 10 days ago has brought out quite a number of tent-caterpillars [Clisio- 

 campa americana]. They are less apparent now, possibly because of 

 the cold weather. Bud moths [T m e t o c e r a o c e 1 1 a n a] are present in 

 some numbers, but they have not caused much damage. Many young trees 

 in this section are badly infested with the scurfy bark louse [C h i o n - 

 asp is furfur a]. May 2. The recent cold weather has greatly reduced 

 the number of tent-caterpillars. Many of the nests are smaller than 

 usual and contain numbers of dead caterpillars. There was an enormous 

 supply to begin with and there still remain a goodly number. This insect 

 was probably four times as numerous as last year, and the cold weather 

 may have reduced its numbers by one half. There is a large increase in 

 the numbers of the forest tent-caterpillars [Clisiocampa disstria] 

 which are just appearing. There is a total absence of aphids up to date. 

 May 12. The estimated reduction of one half in the number of tent- 

 caterpillars now appears too high, still many were killed. They are more 

 abundant than they have been for 20 years, with one exception. May 

 21. The past three weeks have been pretty fully occupied fighting cater- 

 pillars, but that is nearly at an end now. Currant worms [Pteronus 

 r i b e s i i] are present in about average numbers. Cut worms have been
