This

Under

the

head

of

" Short Notes and Exhibition

of

Speci mens," Mr. Fernow

referred to the recent increase of pin-holes ⁱⁿ

timber from

the

Southern

States.

The

insect

producing

^the

damage

is

probably some

Ptinid_beetle,

but

thereisa possibility that ^it

may

be

a Scolytid.

He _expressed

the

hope

^thatit

would _prove

to

be

the _latter, since then its

ravages may ^be

^{met. If it turns outt}

be

a _Ptinid,

however,

there is little

hope

^{of a}

remedy

^{unless it}

should be

ascertained that

deadening

^{the trees at}

another

season

than

that

now _employed

will

prove

efficacious in

preventing dam

age.

He

pointed out theinteresting fact thatthe rapidly

growing

interest in forest

management

^{in the}

^United

^Stateswill,

^no

doubt, afford careersfor future

economic

entomologists.

Mr. Schwarz

statedthat pin-holes, so called, are

caused

either

by

^{Ptinids or}

by

^insidefeeding Scolytids,

and _spoke somewhat

at length

on

the habits of these

groups. He showed

furtherthat

damage by

^{beetles of the}

genus Lyctus

^is

becoming

vastly

more common than

it

was even

a

few

_{years ago,}

and

that

he

is ata loss to

account

for thisincrease, unless there has

been some change

ⁱⁿ the

method

of

drying

^timber.

Dr. Smith showed
