caterpillar are flying in vast numbers ; buckwheat in bloom is covered 

 with them. Grasshoppers injuring crops some and rendering pastures 

 and meadows bare. Aug. 22. In gathering up a bundle of corn, a man 

 was stung on the arm by a larva [Automeris i o , the io cater- 

 pillar]. The injured limb swelled, stiffened, was much inflamed and 

 pained considerably for two days. Larva of [Philampelus pan- 

 do r u s ] was taken on a raspberry bush. Aug. 28. 



Genesee county (J. F. Rose, South Byron) — Last year was called a 

 tent caterpillar [Clisiocampa americana] year, but it must have 

 been a seeding for this. Where they have been controlled each year, 

 they are easily taken care of this season. Many let them increase along 

 the highway on seedling apples and wild cherries. Canker worm numer- 

 ous in places where it has been in past years. Honest spraying controls 

 them, but many farmers neglect this till the trees are brown and the 

 worms large. Those who used wire traps either did not get them on in 

 time or the females laid their eggs in the fall. A few pear psyllas [P. 

 p y r i c o 1 a] found, but they have not seemed to develop. Common 

 asparagus beetle [Crioceris asparagi] already noticed by one 

 grower. Currant worms [P t e r o n u s r i b e s i ij appeared as usual, but 

 were quickly killed by spraying with arsenite of lime and bordeaux 

 mixture. May 20. Apple tree tent caterpillars never so bad before. 

 For the past 10 days they have been crawling everywhere. Some of the 

 largest orchards show hardly a green leaf as the result of canker worm 

 attack. One grower used 1^ pounds of green arsenite to 150 gallons 

 of water in combination with bordeaux mixture and failed to kill the 

 nearly grown canker worms. Pear psylla is very numerous this year and 

 orchards are in bad condition, the small crop is dropping. There are 

 two to 10 psyllas on the stem of each pear and the new growth is badly 

 infested. I thought I could control it, but today am doubtful. I 

 w r atched it closely and did thorough work before the mature insect 

 appeared, used 10% kerosene oil (tried 15% on trees but the foliage was 

 injured). As checks drenched some trees five times but mother insects 

 are numerous today. Forest tent caterpillar [Clisiocampa d i s - 

 stria] is said to be stripping forests infested last year. June 6. Work 

 of the forest tent caterpillar is not yet as serious as last year. Colorado 

 potato beetles [Doryphora 10-lineata] are scarce. Squash 

 bugs [Anasa tristis] and striped cucumber beetles [D i a b r o t - 

 ica vittata] are as abundant as usual. June 22. Find a few nests 

 of the fall web worm [Hyphantria cunea]. Farmers complain 

 very little of potato beetles. Forest tent caterpillars have not caused one-
