9. Trees about six miles north are nearly defoliated by forest tent cater- 

 pillars [Clisiocampa disstria] though there are s arcel) a y 

 in the immediate vicinity. Horn fly [H a e m a t o I) i a s errata] is 

 present in large numl>ers Man\ orchards are lit trail > covered with the 

 scurfy bark louse [('hi on as pis fur fur us] June 3. (<1 rado 

 potato beetles are abundant and doing much damage. Grasshoppers 

 are very numerous July 7. Grasshoppers are doi> g much damage to 

 oats. July 31. White grubs are plentiful in old meadows and hoed 

 crops. Aug. 12. 



Wayne county (C. H. Stuart, Newark) — B >th spe ies of asparagus 

 beetles [Crioceris asparagi, C. 12 -punctata] occur here. 

 The work of the wheat midge [ ? D i p 1 o s i s tritici] was extrt mely 

 bad last year. Apple tree tent caterpillars [Clisiocampa ameri- 

 c a n a] are doing great damage; we have f und it necessary to send 

 men with ladders to kill them by hand. May 20 Apple tree tent cater- 

 p liars are now full grown and seekii g places to spin up. June 2. 

 Larvae of apple tree tent caterpillars have disappeared, but forest tent 

 caterpillars [Clisiocampa disstria] are nearly as abundant on 

 walks as the other species have been. June 7. Larvae of rasp'ierr) saw 

 fly [ Monophadnoides rubi] are doing much damage, the 

 leaves of the infested patch looked today like those of a I) dly infe-ted 

 currant bush. There is hardly a leaf in the field without several holes 

 in it, and most of the older ones are < aten to threads June 12 Work 

 of the fly [C e c i d o m y i a destructor] is very bad in wheat, a 

 great amount of it bring down. July 1 1. There is 1 o exigence of w<>rk 

 by the wheat midge, the clover midge [C e c i d o m y i a I e g u - 

 m i n i c o 1 a] and the onion thrips [T h r i p s tabaci]. The 12 

 spotted asparagus beetle seems to have di-appeared. N arly on third 

 of the wheat is down am! the damage may be perhaps one fourth of the 

 entire yield, the result of Hessian fly work. It was specially bad on 

 early-sown fields. July 25. A small green Lirva [subsequent^ idei tified 

 by Mr Chittenden as the red banded leaf roller Lophoderus tri- 

 f e r a n a] was found eating the green popcorn; it has attacked about 

 2 7% °f th e ears ar "d 37% °f the corn on the ear is destroyed. Sep. 19 



Yates county (C. R. Crosby, Crosby)— Grape vine flea beetles 

 [Haltica chalybea], though nearly as abundant as last season, 

 have not done the damage they did last year, as growers knew what to 

 expect and caught them as soon as they appeared. The warm weather 

 lessened their destructiveness by bringing the foliage out faster. No
