Bonie years ago from Hillsboro, Mo., attacking the peach." Probably 

 it has occurred uurecogQizecl,in many orchards since that date, where 

 its work was referred to that very comprehensive affection termed 

 ''blight." However, daring the past spring several correspondents of 

 the ''llaral World" and the St. Louis "Republic" discovered the minute 

 beetles emerging through the pin-hole-like orifices in the bark of twigs 

 and small branches of peach, plum and cherry, and specimens were sent 

 to me for determination and for the purpose of finding a remedy. From 

 Clayton, in St. Louis county, Mr. J. W. E. Bellvilie, one of the county 

 officials, sent me specimens of the insect early in May, emerging from 

 twigs of cherry, with the information that one or two of his trees had 

 already been killed by them, and that the beetles were so numerous 

 that he feared the destruction of his entire orchard. An examination 

 of the twigs revealed a large number of the beetles, and under the bark 

 a few full-grown larvae and pupte. The beetles were engaged in boring 

 back into the twigs — in every case, so far as noticed, entering through 

 the latent bads and even through some that were unfolding. 



By August the trees severely affected had lost most of their leaves, 

 the bark of the branches was shrunken and the twigs were breaking 

 off. Beetles were again found making their way back into such twigs 

 and branches as showed a measure of vitality. Very few larviie were 

 found in the portions of the trees examined, and such as were discov- 

 ered were ready to transform, indicating the double-broodedness of the 

 insect. Mr. Bellvilie wrote me thit he thought he had protected some 

 of his trees by spraying at this time with Paris green. So far as I have 

 been able to find out by personal examination and inquiry the insect is 

 yet quite local in the State, and if horticulturists can be brought to 

 realize the danger of neglect in this case, it can no doubt be held in 

 check, if not entirely stamped out. 



TJie Pear tree Glear-wlng Borer in Apple. — This insect {^^geriapyri 

 Harr.) appears for the first tim?, I believe, to swell the ranks of the 

 almost innumerable pests of the apple-tree, upon which it may prove 

 more injurious than it has hitherto done upon the pear. 



Early in May I received from Mr. S. W. Gilbert, of the Flint Hill 

 fruit farms, in Oregon county, a few small lepidopterous larvfe taken 

 from the young apple-trees, with the information that "the worms eat 

 the inner bark next to the hard wood, and are usually, if not always, 

 concealed at least one-eighth of an inch from the dead bark." Mr. 

 Gilbert further says: "I find the insects especially abundant on trees 

 that have been 'sun-scalded' on the southwest side. They work at the 

 edges of the green bark next to the dead portion of the tree. Among 

 the young Missouri pippin trees last year I found a large number that
