ALBANY, n. V, June 19.-" The meteorological
conditions OF tho past winter seem to have bceh
favorable to tho multiplication of insect life. :,
says Prof. ]. A. Lintncr, the State entomologist
Several OF our common insect pests havo APP
peared in larger numbers than in many precesr
Ing years.
Among the earliest to intrude itself upon
general notice has been the common apple-tre6.
tent caterpillar Ciisiocdmpa americana. 40
cording to accounts received, II has not been so
abundant in n number OF years past. Tho foliage
OF many orchards has been injured to such an
extent as greatly to impair tho fruitage, unless
tho thousands OF caterpillars-at times from
twenty or more nests on n single tree
have been destroyed while they were yet young,
This serious destruction could have been easily
prevented by cutting Off tho egg clusters from
tho tips of tho branches whio the trees wore
leafcss, or twisting out the web nests from tho
| forks Of the branches in the morning or evening
when tho caterpillars occupy them and crushing
them under foot.
"Tho whitc.marked tussock moth. Oropia
ieucostiamd, is a notorious pest Of several Of onr
shade trees in Cities especially where 1t occurs
In two broods each year. in the city Of Now
York and southwark. If the remedy Is adopted
of collecting its snow-white egg clusters from
the trunks of trees, fences beneath window sills
and wherever the cocoons are placed, whilo they
are readily seen and before they become discol.
ored with age. the continued defoliation Of our
shade trees may be largely prevented.
The army worm, Leucania unipunctd, which
was more extensive than usual in It's distribu-
| ton last year throughout tho State Of Now
York and neighborlng localities, II past records
OF the insect arc to be relied upon, will not APP
| pear in very destructive numbers in the 1ocali-
ties then infested. during the present year. Its
| parasitic enemies will have kept 1t in check.
The spring canker worm, Anisopteryr cer.
| natd, which for long time has been 30 destruo-
tive in the Eastern States, is multiplying in tho
| State OF New York. 1t is not difficult insect
| to control. through spraying the foliage Of I'm
| tested trees with Paris green and water as soon
| as the young caterpillars make their appearance.
Later the poison is less effective and q much
stronger mixture is required to kill the nearly
mature Larvae.
"The elm-leaf beetle, Guleruceild luteolG, IN
continuing its spread with rather slow but
| ct eady progress over the region in New York
| where climatic conditions favor its existence.
| For the past two or three years 1t has been do
structive in Albany, having already killed q
largo number OF our introduced elms and has
extended northward along the Hudson River
Valley. In all probability It will soon be heard

water for killing the larve when they first ap-
