it lived in a pill-box until

January

and

in the Mule,

CYNIPS STROBILANAOsten Sacken

Galls of this species

were

collected on Que7xus hicolor at River

Grove and New

Lenox,111.; at Ironton,

Mo.

;

and

at Great Falls, Va.

They

were

found on

Q. 7nacrocarpa at Algonquin, 111., at Fort

Worth,

Tex.,

and

Miss

Howe

^collected

^them

^{at Ithaca, N. Y.}

^Wil-

liam Beutenmueller writes that they were very

abundant

in the fall of 1922 at

Highwood.

N. J. Galls collected in Chicago area

Novem-

ber 1, 1914, then contained a

few

adults as well as larvae.

When

opened April 24, 1916, larvae

and

living flies were

found

in about equal numbers. It is inferred that

some

flies

emerge

each spring for at least three seasons

and Packard

records finding an adult

and

a

pupa

in galls six years old. Galls were collected on Q. lyrata ^at Poplar Blufi^, Mo.,

and

at

Hoxie and

Texarkana, Ark., in

November,

1917,

when

the fresh galls were almost solid

and

cut like cheese

and

the old galls contained

pupae

or adults

which emerged and

died in breeding cage before the middle of the next

May.

CYNIPS SULCATA Ashmead

Described

from

^'*live oak^"

from

Fort Grant, Ariz., the writer has collected galls

and

reared flies

which

agree with the

Ashmead

types

from

QuercuH arizonica^ ohlonr/ifolia^

and

reticulata.

The Ashmead

type galls seem to be

on

Q. aHzonica. Galls

on

ai'izonica collected

December

17 at Oracle contained pupae, adults

emerging

April 1-27. Galls

from

the

Mule Mountains

contained adults

and pupae

on

January

13, flies

emerging

April 25. Adults

emerged

April 16-26

from

gallscollected in the Chiricahua Mountains. Galls

from

the

Tumacacori Mountains

gave flies

March

8, April 6

and

26.

In the Santa Rita

Mountains

on

December

7 galls on Q. ohlonglfoVia weregreenish or if in the sun mottled with pink

and

just beginning to harden, containing full-grown larvae. Living flies were cut out on

February

4. (xalls were observed at Prescott. Nogales, Bisbee,

and

Patagonia.

CYNIPSWASHINGTONENSIS Gillette

The

species

was

described

from

one specimen

from Olympia.

Wash.,

from

Q. garryana.

McCracken and Egbert

reported it on Q.

lohata. du77iosa,

and

durata.

The

writer has collected galls on all these hosts

and

on Q. douglasii also as follows: on Q. garryana at Shelton

and

Tillicum. Wash., at Odell, Albany, Corvallis (adults nearly all

emerged by August

24, 1916), Cottage

After the description of this species in 19ls

more

flies issued

from

the original lot of galls (collected in fall of 1914) on

March

24

and

April 10, 1919.

The

next spring the cage

was

not

examined

until

May

1,

when molded

^{flies Avere}

found

that probably

emerged some

weeks earlier. This

makes

it certain that the emergence of the species

was

distributed over at least five seasons

and

probably six.

In addition to the published data on distribution, the Avriter has seen galls at

Washington,

D. C.; Bluemont, Va.; Marianna, Fla.; Tex- arkana. Ark.; Ironton

and

Poplar Bluff.
