been observed where in former years trees were defoliated by 

 them. Though the forest tent caterpillars [Clisiocampa 

 dis stria Htibn.] have been numerous, they have not been so 

 abundant as last year, and they are now in the pupa or cocoon 

 stage. Some maples have been badly defoliated by this pest, 

 .lune 20. Aside from the forest tent caterpillar, we have been 

 remarkably free from insect pests. These caterpillars have in- 

 flicted considerable damage on hard maples, our principal 

 shade trees. June 23. A few elm leaf beetles have made their 

 appearance, though but little damage has been caused. The ex- 

 tremely wet weather has kept insects pretty well in check. Potato 

 beetles have been scarce and easily controlled. July 18. 



Erie county (J. F. Metz, Swormville) — Asparagus beetles 

 [Crioceris asparagi Linn.] have been exceedingly num- 

 erous this spring and much more abundant than in former years. 

 No currant worms [Pteronus ribesii Scop.] have appeared 

 so far and few potato beetles. A very little Hessian fly 

 [Cecidomyia destructor Say] has been observed in a 

 neighboring wheat field. May 28. Hessian fly has been found 

 only in very small numbers; probably less than 1^ of wheat is 

 infested. There appears to be no more of this pest on no. 6 wheat 

 than on more resistant varieties. The bud moth [T m e t o c e r a 

 o eel Ian a Schiff,] is scarce, and no indications of the palmer 

 worm [Ypsolophus poraetellus Harr.] have been ob- 

 served. Not a single nest of the appletree tent caterpillar [Clisi- 

 ocampa americana Fabr.] has been found. June 20. 



Genesee county (J. F. Rose, South Byron) — The first asparagus 

 beetle [Crioceris asparagi Linn.] was observed May 25, 

 and the currant sawfly [Pteronus ribesii Scop.] had 

 lopped young currant shoots by May 23. There is a little com- 

 plaint of potato beetles [D o r y p h o r a 10-1 i n e a t a Say] work- 

 ing on tomatoes. No injury by Hessian fly [Cecidomyia 

 destructor Say] has been reported, and appletree tent cater- 

 pillars [Clisiocampa americana Fabr.] do not appear 

 to be as abundant as last year. Currant worms are rarer. May 

 26. Appletree tent caterpillars are certainly much less numerous 

 than last year. There are not nearly so many to be seen along the 

 roadsides, and their scarcity in these places is attributed to the
