OUTSTANDING S3TCKCL0C-ICAL P3ATUIC3 I." THE 0HITHD STAT3S FOR SIPTI2£32R, 1S23

No findings of the Mediterranean fruit fly have been reported during the
month of September.

The rather serious conditions with regard to grasshoppers reported in the
last number of the Bulletin have developed into serious outbreaks in the Great
Plains district of North Dakota and Montana.

Serious depredations by wire^orms continued to be reported from scatter-
ed localities over the entire country, the damage being particularly serious
on the Pacific Coast.

The very light Hessian fly infestation reported from Nes* York State
last month apparently extends westward through Ohio. The detailed summary

of the Illinois su.rvey, on the other hand, shone a very marked increase in
infestation, the average of infer* tod straps for the State being about 15
per cent. Hessian fly seems to be on the increase also in Missouri.

Very serious depredations by corn root '.vorms have been reported from
Iowa and Nebraska. Large patches of corn are completely killed out in many
districts and much corn which was not 2cilied was lodged on account of the
destruction of the roots.

The velvet bepn caterpillar is practically ruining the soy bean crop in
southern Louisiana and along the eastern coast of Texas. The streaige feature
of this outbreak is the fact that velvet beans and cowpoas adjacent to ruined
fields of soy beans are practically undamaged.

Cowpeas in the coastal plains district of the Carolines axe so seriously
infested by the cov7pea curculio that many growers are net recovering their
seed.

• During August the alfalfa weevil was discovered in the vicinity of Bed-
ford, Oregon. This appears to be a commercial jump as the nearest known in-
festation is -ZOO miles distant in eastern Oregon. This insect was also found
for the first time in Alpine Cour/,yx California, this being an extension of the
Carson Valley, Nov., area.

Owing to a partial third brood of' the codling moth developing in the
Middle Atlantic, East Central, and '.Vest Central States, late injury by the
worms is very noticeable, even in 'jell sprayed orchards. Serious conditions
have also been reported from Nevada and Washington.

More damage by the apple maggot than usual is being observed in the New
England States.

The apple fruit worm (Argyrcstbis corougclla Zell.) has been observed
for the first time in the Montesano section of Washington.

A very interesting case of the complete control of an insect pest by
its natural enemies is re-ported from Chio, where the apple flea weevil has
been practically eliminated this year by its hymencpterous parasites.

The oriental fruit moth is recorded for the first time from the northern
end of Indiana and also from Amherst, Mass., and is quite generally reported
from practically the entire infested region.

The grape berry moth has very materially increased in abundance in the
Lake Shore district of Chio and over practically the entire State of West
Virginia.

The fall uebworm Is "unusually abundant throughout the South Atlantic and
Gulf Coast region extending up the Mississippi Valley into Missouri.

The European weevil, Brachyrhinus cribricollis Gyli. , has been discover-
ed on citrus and privet in Los Angeles County, California.

The citrus vhitefly is being reported as very abundant from Florida and
the Gulf Coast section.

Very serious damage by the garden web™orm to alfalfa is reported from
Iov7a and Nebraska.

The curculionid beetle , Tvledorma morbillosa Lee, is recorded for the
first time as a strawberry pest in "Vashingtor.

The pickle worm appears to be much more serious than usual in the North-
ern part of its range, reports coming from the East Central and the West Cen-
tral States. The insect is recorded for the first time from ITobrasIta.

Tvo heretofore unrecorded species of springtails are doing commercial
damage to mushrooms in Minnesota and Missouri. The species in Minnesota
belongs to the ^enus Achoreutes and the species in Missouri to the genus
Schottella.

tent

A very interesting account of an outbreak of the great basin/caterpillar
appears in this number of the Bulletin. The outbreak took place near Mount
Shasta, California, and the worms ncre so numerous that they prevented rail-
road trains from making the grades. Special equipment v:as required on the
locomotives to meet the emergency.

- 313 -

The satin math has been recorded for the first time in woodland dis-
tricts in New England.

The hemlock spanworm has killed practically all of the hemlock in the
resort region of Michigan and is now 'seriously damaging hardwood.

A very heavy infestation by the two-lined, prominant (Hemerocampa
bilineata Pack.) attacking beech and oak is reported from Michigan.

A considerable part of the Nhite fountain district of New Hampshire,
a large part of Vermont and Maine, and parts of Massachusetts seem to be
well infested by the birch leaf-mining sawfly.

OUTSTANDING ENTOMOLOGICAL 73ATUBES III CANADA FOE SEPTEMBER, 1929

The general application of control measures against the European corn
borer has had very favorable results in Ontario. In spite of this, observa-
tions indicate that in Kent and Essex counties sweet corn was more heavily
infested than last year, although in the case of field corn the increase was
only slight. The presence of this insect in Quebec has not yet caused seri-
ous crop injury. In New Brunswick, in Sur.bury and -Queens Counties, the in-
festation is extremely light. As a result of scouting, the borer has been
found in Nova Scotia, in Yarmouth, Digby, and Annapolis counties.

The grasshopper infestation in British Columbia, while not extremely
severe as in 1926, again shows a tendency to increase. The exceedingly dry
summer enabled the grasshoppers to lay their eggs successfully. Moderate
outbreaks of grasshoppers alsc are reported from southern Quebec and south-
eastern Prince Edward Island.

Severe injury by white grubs to a vari sty of field and garden crops is
anticipated over a fairly wide area in southern J»ue'.ec, in late fall, and
during the soring of 1930.

leather conditions have been favorable to the development and increase
of the wheat-stem sawfly in southern Manitoba, but loss to wheat and rye
does not excoed a few thousand dollars for the whole province. Damage to
wheat by this species, in Saskatchewan, is believed to be moderately severe
generally throughout the infested areas. Although tne infestation is not sc
great as in former years the rate of damage appears to bo unusually high.

Heavy infestations of the turnip aphis are reported from districts of
southern New Brunswick and locally in southern Ontario. The pea aphis lias be
reported in great numbers north of Lake Ontario in the counties of Prince
Edward, No r thumb orl and, and Durham, and also in southern Quebec.

- 314 -

There is a heavy infestation of the imported cabbage worm in southern
Manitoba, resulting in the probable destruction of half the cabbage crop in
farm gardens. The infestation covers all districts of Manitoba south of the
main line of the Canadian Pacific Railway, becoming less northward, but
being present at Swan river, north of latitude 52°.

During the sisnmer the tarnished plant bug occurred in very injurious
numbers in southern Ontario, causing considerable damage to garden plants
and nursery stock. Particular!;/ severe injury was caused to the celery crop.

In districts of southern Saskatchewan, the bertha armyworm, Barakhra
conf ifurata ~lk. , caused considerable damage to cabbage and flax and some
injury to corn and other crops. The infestation apparently is not so ex-
tensive nor the damage so severe as in 1923, but this species is probably
the most severe pest of cabbage this season in t". e area involved.

An outbreak of the zebra caterpillar has been reported from districts
of s out horn 17ew Brunswick, southern <.uebec, and Ontario, affecting crucifer-
ous plants and a variety of other flowering plants and vegetable crops.

The European red mite has been very conspicuous in the Niagara district,
Ontario, particularly in plus orchards, and also along the St. John River
Valley, New Brunswic-c, in apple orchards. An outbreak of the red spider,
Tetranychus telarlus L. , occurred in all parts of Manitoba, south of lati-
tude 52°, affect:.:..: raspberry, currant, bean, pea and many othor plants.

In addition to the heavy outbreak of the green apple aphid in southern
Ontario already reported, a largo percentage of the apple orchards in the
province suffered injury from the rosy aphis, Anuraehio ro s eus Baker.

A heavy outbreak of the apple maggot in .;any parts of Ontario, east of
Toronto, was prevented by spraying. There has been a greater menace from
this soecies in Ontario curing the last four vears than in any previous period
in the past twenty years.

GENERAL FEEDERS

GRASSHOPPERS (Acrididae)

J. R ".Tats on (September 23): Grasshoppers arc doing con-
siderable domegc to citrus over Plorida.

H. C. Scverin (August 30): The outstanding outbreak in
South Dakota at the present time is an outbreak of grasshop-
pers. Helanoalus f emur- rub rur.v DeO. , M. dif f orentialis Thoa.
m. bivittatus Say, and M. at! mis Riley are very abundant in
Lyman, Jones, Jackson, Pennington, Meade, Stanley, Hughes,
Haakon, Buffalo, 3rulo, and Gregory Counties, attacking
alfalfa chiefly.

K. H. Svonk (September 3): Oaring the first half of August
grasshoppers continued to be numerous and injurious in vege-
table and flower gardens in the vicinity of Lincoln and
around parts of Omaha, Jrcmont, Columbus, Kearney, and clSw-
whero in the Platte Valley.. -Souse damage to alfalfa -/as re-
ported from Thayer County late in August. Injury was seriate
in come alfalfa fields in south/ester/. :Jebraska from Banner
and Deuel Counties to Cease and Hayes Counties. Some appre-
hension is felt by farmers in this area that the grasshoppers
..iay do severe damage to the viator wheat planted this fall,
as the insects are more numerous than usual at this time.

S. Greene, jr. ,and L. 0. Baumhof or (September 2): Upon
examination of yell 0*7 pine at the western edge of the planta-
tions, a replant on the 1927 burn, vo found most of the trees
dead. The heavy loss appeared to be the work of grasshoppers .
Many of the trees had almost tae entire stem girdled, others
had their stems cho"*od off above the ground, and still others
had most of the foliage destroyed as fell as being partially
girdled. A count of several ro'-s showed a loss of about 86 per
cent out of 1,200 tr^es examined while some of the remaining
trees were partially injured in the part of the plantation
examined. : Damage to this year's planting on another area
appeared to be much lighter, •; robe- oly about one- third of the
above. .This is tee most severe damage -of this type noted thus
far since field work began at Halscy. A for grasshoppers
caged with small seedlings have caused similar damage to
these trees. Most of the destruction probably occurred in July
as there *?as no damage when the plantation was examined in
June a'/d there is little fresh *"'ork now. ; . Trees planted
in the last two or three years are most susce :tible and yel-
lof; -pine is damaged most severely.

%. C. Sullivan (September 23): Grasshoppers are very abun-
dant . The species include Helanoolus femur- rub rum DeG., h.
cliff erentialis Thos . , Ccnocephelus sp. , and Are hi a pseuho-
nictana Thorn.

•*! 16*

dorado C. F. Gillette (September 21): Grasshoppers are moderately

abundant in northeastern Colorado, many calls for grasshopper
poisoning having been received.

loatana 3. Habee (September 21): Grasshoppers, y.elanp-olus

ironic anus bivittatus Say et al. , have increased their popu-
lation-; over the entire eastern half of the State and are very
abundant in Boosevelt, McCond, Hi ch land, Da-son, and parts
of Toole, Liberty, Chouteau, "Pondera, Hill, and Cascade
Counties, and in one place only, Lake County, -est of the
Divide.

California Monthly Hers Letter, Los Angeles County Agricultural Comm.,

Vol. 11, SO. 3, August 15: Continued periodic inspections of
what have been grasshopper breeding grounds in the Antelope
Valley during previous years .indicate that oving to the al-
most entire absorce of "hoppers11 in those loaclities there
"•ill not bo any necessity for control operations this season.

Washington nr.. 7.'. Baker (August 29): A report "'as received that

grasshoppers ""ere thick in one of the tail office buildings
in ' Tacora . rnat appeared to be this species (Kelano^lus
atlanis Hiley) "as found in fairly large numbers clinging
to the rails ana cn the sideralks. These had likely bred
in the cut over region rest of Tacoma.

Uabama C. T. Been and L. L. Odbm (August 30): On August 20 some

soil sifting for He teredo res laurentii Guer. ras conducted
near Foley. A series of soil plots 12 in. square and 4 in.
deep re re sifted. The populations of larvae rere found to
range from none in somo of the plots rherc Irish potatoes had
been grorn a-s the spring crop and follored by late corn, up
to 9 larvae per square foot in turnips. Old corn and heavily
: ras sod hedoe rors shored an average of 3 larvae per square
foot. It v-culd seers that adults gradually moved over to pol-
len-hearing plants such as corn and the various comcn native
grasses. Larvae of ell sizes from the very smallest to the
full-grc-n ones rere found. Horcver, the greater number rere
approximately the seme size, indicating a peak of hatching.
Larvae of this s :ecics attain almost full sise in tro or tro

by the entomologists of the Natural History Survey and Federal
Bureau of Entomology cooperating has just been completed.
The survey this year shows a very marked increase in the Hes-

an increase in northern Illinois, but it is not so great and
the infestation in this section is not so heavy as in the cen-
tral and southern counties. The infestation runs generally
from 3 to 35 per cent and -'ill average around .1.15 per cent.

of damage was done to oats and to a much less extent to corn.
In several instances farmers reported that fields containing
30 acres of oats had been totally destroyed before they were
aware of their presence.

CORiT

CORN EAR "CHI..: (Heliothis obsoleta Fab. )

7. 3. Eritton (September 24): This insect seems to be mere
abundant than usual on corn in New Haven, 7/codbridge, and
Plainville. .

E. L. Chambers (September 1): Sv;ect corn and pop corn are
being injured to some extent in Racine, Milwaukee, Kenosha,
and 'Talworth Counties, according to inquiries received for its
control and specimens submitted.

C. N. Ainslie (August 28): Field corn in the district of
Sioux City seems unusually free from this pest this season.
Early sweet corn *.7as badly injured.

FALL ABLTT70HM (Lauhygma frugiiaerda S. & A.)

J. R. Watson (September 23): The fall army.vorm has been
more or less abundant in the western part of the State for
some months and is beginning to make its appearance in certain
isolated regions in the peninsular part of the State. The dam-
age is chiefly to grass and sugar cane.

B. ST. Harned (September 23): Injury to sugar cane at
Natchez and to corn at hetcalf was reported on August 23.

R. I'i Colmer (September 20): ~e have had an infestation
in Moss Point and Pascago.ula. In some cases they have eaten
the grass from entire lawns.

EUROPEAN COPuT 2CRER (Pyrausta nubilalis Hbn.)

A. L. Stene (September 25): Moderately . abundant ; spotty
second brood abundant in some locrlitics.

T. H. Farks (Sa-ot amber 23): Moderately abundant; increased
in northwestern counties.

CORK ROOT ;7GR£iS (Liabrotica syp.)

G. J. Drake (August 29): D. duodecimwunc tata Fab. and D.
lorgicornis Say are abundant over the entire State and here
and 'chore are causing a considerable amount of commercial dam-
age. In several instances the roots were almost completely
destroyed and after a heavy rain the corn fell to the ground.
The western corn root worm seems to be the more abundant.

R. L. Parker (August 29): The western corn root worm has
been ro-oortod as cutting roots of corn at Lebanon.

-321-

Nebraska M. PI. Swenk (September 3): During the month of August

there was much serious trouble with corn root worms in several
sections of the State. The corn was killed out in large
patches, and there were many fallen stalks in the affected
fields. Two years ago (1927) there was similar trouble with
this pest, but little or none last year. D. longicornis Say
was especially troublesome in Valley, Sherman., and Buffalo
Counties in the central part of the State, and also in Keya
Paha County to the north and in -Tebster, Nu.clbo.lls , and Jeffer-
son Counties along the southern boundary of the State. The
Colorado^? oot worm (]). virgif era Lee.) was similarly trouble-
some in southwestern Nebraska (Hitchcock County).

FLOuER BEETLES (Euphoria spp . )

North Carolina C. H. Erannon (September 4): Flower beetles of this genus
are causing noticeable injury to corn in Caswell County.

SOY IgSftNS

VELVET BEAN CATEilPILLAR (Anticarsia ^emmatilis Kbn.)

Louisiana E. Hinds (September 20): This insect is very abundant

in the southern half of the Stacc. It has appeared this year
in greater abundance than ever before, stripping soy beans as
completely as the ccttcn leaf worm does cotton. C-utbreak ap-
peared first in the vicinity of Jeanerettc and stripoing be-
came general at Baton Rouge by the last of August. Another
generation is in prospect. Poisoning has checked worm feed-
ing promptly with some burning of foliage which has not been
nearly so serious as the worm stripping. "Tnere worm feeding
was stopped by poisoning the buds were saved and started new
growth promptly. V,rhere worms were not poisoned and were abun-
dant they frequently destroyed buds so completely that new
foliage was not formed. The s^od crop of several varieties
of soy beans will be materially reduced in Louisiana.. Natural
control of these worms has been noticed especially through the
feeding of birds, the attack of wasps, and attack of a white
fungus, presumably Eimousa rileyi , which is causing the death
of large numbers of larvae.

T. E. Kolloway (September 17): Mess . s . J. .7. Ingram and
"7. A. Douglas have found an infestation ranging from ITapoleon-
ville through southern Louisiana to the Texas line. The only
crop attacked is soy beans, except cotton growing next to soy
beans. Unless checked, the caterpillars defoliate the soy
beans plants and then feed on the remaining stems, finally de-
stroying all life. ' Curiously enough, neither velvet beans nor
corrpcas, even when growing next to soy beans, is attacked.

J. 7. Ingram (August 27): On August 27 a plantation was

-222-

visitod in Assumption Parish "/hero 100 acres of soy beans
had been completely defoliated. All leaves and small twigs
ead been eaten, so the plants resembled sticks stuck up in
the field. Cnly a very small number of worms were found, but
6 pupae v:crc found after digging in 1 square foot of soil.
The ov/ncr stated that the worms appeared so suddenly and ate
so fast that his beans ':ere destroyed before the worms were
noticed; 50 acres of soy beans planted in stubble cane were
only, partially defoliated. According to the owner of this
plantation, the worms appeared in destructive numbers in soy-
bean fields throughout this parish and adjoining ones.

Texas T. S. Holloway (September 17): A report from Beaumont

states that this insect is nov;. t o be found near there.

CO". PEAS

CO.. PEA CURCULIO (Chalcodcrmus aencus Boh.)

Tt . A. Thomas (July 15): The cowpea pod weevil has been un-
usually destructive to ccwoeas in practically all of the
coastal section of the Carolinas. In the vicinity of Bennetts
ville, S. C, many growers claim that they are scarcely
getting the s^cd they planted as a result of this insect's
work. Single pods wore observed to have more than 50 punc-
tures for feeding end oviposition.

North Carolina
and

South Carolina

:-rass

cut'.:0FJv:s (Hoctuidae)

Arizona 0. L. Barnes (September 18): Severe damage to golf greens

of bent grass by cutworms near Phoenix has been observed. The
. damage ranged from about 15 to 100 per cent considering the
greens individually. In some cases no grass at all was left.
Peltia anncxa Treit., Agrotis yosilon Pott.?, Prodenia ornitho
galli Gucn., and an undetermined species v/ere present,, A.
vpsilon was present in greatest numbers, folld-^ed closely by
F. ahnescfc., while the latter two species were relatively much
less numerous. The golf course was desert land a year ago.

A SCALE INSECT (Aclerda cbscura Parrott)

North Carolina C. H. Brannon (September 2): This scale was collected in

Moore County near Cameron on sandhill dominant grass (Aristida
stricta) . Dr. H. Morrison who identified the specimen fur-
nished the following information: "Appears to be cur first
definite record since original publication of species. Com-
pared with co-type."

ALFALFA

ALFALFA TiEEVIL (Fhy to nomas posticus By 11.)

Uovada 0. 0. Schwois (September 13): Adults are seeking alterna-

tion quarters.

Oregon D. C. Koto (August): The alfalfa weevil "as discovered in

the vicinity of Medford early in July. This a commercial jump
since the nearest known infestation is some 200 miles from
Hedford in eastern Oregon. Rockwood and Mote made a prelimi-
nary survey, determining the limits of the infestation at
Central Point on the north, Phoenix on the south, about 2
miles west and two and one-half miles cast of Mcdford. One
peculiar feature of the infestation was the lateness of weevil
development. The larvae -ere feeding and doing damage to the
second crop of hay which was nearing maturity.

California S. Lockwood (Augast 30): Mr. Ceo. .Vilson and the writer

found the alfalfa weevil for the first time in Alpine County,
the infestation being an extension of the area of the Carson
Valley which has been infested for a longer period. This in-
sect was also found to have extended its area by 1 mile with-
in a year in Lassen County.

THHHE-GOBHEBBfi ALFALFA H0PF3E ( Stictocc-phala f estina Say)

Arizona 0. L. Barnes (September 22): Moderately abundant in the

Verde Valley in Yavapai Comity. Abundant in some fields

Iowa C. -J. Drake (August 29): Since my last report we have had

a large number of complaints from a large district in the
western portion of the State. It has been reported in Adair
and Dallas Counties in addition to the counties I named in my
previous letter. Many new fields of alfalfa were very seri-
ously damaged or totally destroyed. ;>uite a number of
gro-ers reuorted that fields of 30 or 40 acres were entirely
riddled.

Nebraska M. H. Swonk (September 3): An outstanding insect pest of

the month wag the garden webworm, the injuries of which ap-
peared in the alfalfa fields over an area enclosed by Douglas,
Ctoe, Fillmore, Adams, York, and 3utler Counties, and also
in Antelope County near iJeligh and Brunswick about August 7
or 8 and did much damage during the following week or 10
days. Complaints of injury ceased abruptly immediately after
the middle of August. i-'Iany fields were heavily infested and
by the time the larvae were matured were so eaten and webbed
that they appeared as if they had been frostbitten or swept

by fire. In Antelope County, Russian thistles and pigweed
"ore much attacked along with the alfalfa. 7/here the second
cutting had been made about the middle of July the damage was
little or none, but in the affected area there was considerable
in fields cut late in July.

appeared in northern and central Virginia this season. This

brood increases the number of w^rmy apples even in sprayed
orchards .

T. 5. Parks (September 23): This insect has increased
over last year and "stings" of the late worms mark apples on
some of the best sprayed orchards.

J. S. Houser (September 24): Moderately abundant throughout
the State.

J. J. Davis (September 23): Reported as very abundant at
Hew Castle on September 13. It is more abundant and destruc-
tive this year than last throughout southern Indiana.

APPLE FLEA ..'EEVIL (Orchestes pallicornis Say)

Ohio J. S. Housor (September 24): One of the outstanding insect

developments in Chio this season has been the almost complete
elimination of the apple flea weevil by hymenopterous para-
sites. Up until this year the rate of increase by this insect
from season to season was quite disturbing, but in June hymen-
opterous parasites working in larvae and pupae almost completely
eradicated the brood so that late in the summer the insect was
scarcely to be encountered.

CITEOPHTLUS M2ALI3UG (rseudococcus gahani Green)

California Monthly News Letter, Los Angeles County Agricultural Commis-

sion, Vol. 11, No, 9, September 15: The mealybug situation in
the field in Los Angeles County looks more favorable than it has
for several seasons past. The recent protracted warm weather has
not only been responsible for an appreciable mortality in the
younger mealybugs , but has materially increased the activity of
the liberated Cryotolaomus .

The few exceptions to this condition are the result of the
presence of a large zr?y native ant which is particularly active
in protecting the mealybug from its insect enemies, including
the Cryptolaemus .

Liberations of Cryptolaemus from the Inscctary are being
limited to a few orchards in which necessary treatment for
other pests has interfered with the completion, of the control
of the mealybug

CITRUS RLD SPIGSR (Paratetranychus citri McG. )

California E. A. McGregor (September) : A rather thorough survey of the

five southwestern counties of California brought to light the
fact that the citrus red spider is extremely scarce in this

3. Lockwood (August 30): The great basin caterpillar
destroyed the foliage of ceanothus and to a lesser de-
gree manzanita over whole hillsides on the southern
slope of' Mount Shasta near Shasta City, during the lat-
ter part of June. The worms were so thick that trains
were sloped to a standstill on the grades because of
the crushed bodies on the rails. This was overcome by
The locomotives being equipped with steam jets to blow
the worms from the rails in advance of the wheels.
Strawberries and garden peas were devoured also.

KSiiLOCK (Ellooia fiscellaria C-uen. )

E« I, KcDaniel (September 12): For several years the
hemlock iooper has been destroying trees in the resort
region of Michigan. A recent survey mac'e by Mr. Korcf sky
of this department sho'-'s that one plat cf 4S acres of
forest land containing hemlock, pines, and hardwoods has
been seriously attacked at Pentwa-ter. The hemlock is all
dead or nearly so and the larvae -are feeding on the white,
Austrian, Scotch, and jack pines, also on oak, alder,
beech, and cherry. The only trees present that are not
attacked ;re maples and locust. The hardwood is evident-
ly being eaten because of the killing of the hemlock and
pines. At the time cf . the survev (September 5). very few
larvae and pu:ae were present, but many adults were .to
be found.

SAT Ik MOTH (Stilnnotia salicis L. )

Hew- Hampshire ~. C. Craighead (September 13): On August 22, C S.

Hood and J. E. P.. Eolbrook of the gipsy moth laboratory
noted feeding by the young larvae on the foliage of large
trees of the large- toothed aspen, ? o tuIus zx ar.di den tatg
Mich. , growing under woodland conditions in Kingston.
Feeding had been so severe in one small area that the
brown skeletonized foliage was noticeable from a consid-
erable distance and here the hibernation webs were very
abundant in crevices in the bark. This is the first
record the gipsy moth laboratory has of a satin moth in-
festation occurring in a woodland area in Pew England.

BIRCH

3I3CH LZiAT'-MIHIITG SAPTLY (Phylletoma renoratg Pall en)

T. H. Jones (September 20): from letter from Mr.
Mueseoeck: -!Hr. Snaffner and I spent til? period Septem-
ber 11 - 14 in an attempt to obtain some further inform-
ation on the distribution of the introduced birch leaf -
mining sa-'fly. Our observations ■■•ere restricted to He™
Hampshire and Vermont in addition to a few points in
northeastern Massachusetts . 7e followed a route along
the eastern border of Hew Hampshire northward through
Ossip:o. and Horth Coivay to C-orha.m, from there -•est-
v-ard to Lancaster, 17. P., and St. Johnsbury, Vt. , then
southward through Bar re and Rutland to Pennington, Vt. ,
in the extreme southwestern part of the State, and from
Bennington castas rd through Prattieboro, Vt. , Pdchmord
and Pirdgs, P. P., and As hour nha.m and r-roton, Pass., to
Helrosc. "rchi this it will be apparent that • consider-
able section of the 'P.ite Haunt air. district of He™ Hamp-
shire, a large part of Vermont, and a sm-li district in
southern Hew Hampshire were covered, in addition to a.
few points in Massachusetts. Because of the supposed
preference of the insect for white birch, we scouted
particularly areas -here this species is more or less
common, but in these districts other species of bircn
were also examined. G-r?y birch seemed to us to be al-
most as favorable a food plant as white birch, and lar-
vae were also, found in small numbers mining the leaves
of yellow birch. Prom our hurried observations it ap-
pears that it is more abundant in the north and in areas
of considerable elevation. At any rate, the heaviest
infestations noted were on the hillsides in the ""kite
Mountain region of 2"e™ Hampshire. Only one moderately
heavy infestation was found well to the southward at
Marlboro, Vt. , and this on a hilltop at some elevation.
This species was, however, found in small numbers z t

mostly of the pig-nut type, in Bancroft Park in Lansing.
An examination proved that between 400 and 500 tree., were
in a dying condition and that enormous numbers of larvae
were now present. Many adult beetles are still in the
galleries and flying about, although the groat mass of

some infestation. Infestations of 3 per cent were ob-
served in the Tillamook district, one-tenth of 1 per
cent in the Columbia EiVer district, and 1 per cent in
the Willamette Valley.

gated over one-fifth of 1 per cent. In -two plantings
only was any excessive infestation found, and in both
the particular "blocks showing infestation '.'ere bulbs
that had been weakened by frost injur y and sunburn the
previous summer , respectively. Infestation on tulips
at Sunny dale was 0.03 per cent, in Dutch iris bulbs at
Sumner and 3ellevue 0.11 and 0.04 per cent respectively,
and in St. Brigid anemone corms at Bellevue about 10
per cent. This is the first record of this plant as a
host of Zumerus.

DOMESTIC A U I M A L S

FLjlAS ( Ctenoce'oha.lus spp.)

D. C. Bishopp (August) : numerous reports of houses in-
fested with dog and cat fleas have come in during August.
These reports are about equal in number to those of July.
They came largely from the northeastern part of the .Unit-
ed States, with the maximum number from' !'ar~l?~.d and
Pennsyl v an i a. .

Iowa c- J. .Drake (August 29): Fleas, largely cat and dog,

have "been very -abundant in Iowa this year. They seem
to be pretty widely distributed and in several instances
were extremely abundant in the basement and first floor
of homes.

PUSS CATERPILLAR (Hegalo-oyge .p-oer cularis S. & A. )

Mississippi R. W, Earned (September 33);: Larvae of Hegalop2rge,

probably p-oer cularis . have attracted considerable atten-
tion throughout the State during the past month.

A ~ATSR BUG- (Corixidae)

Haiti R. C. Smith (Augast 23): An unusual flight of a small

corixid -'as observed at lights at Petiomville on Augast
28. Residents stated that they had never seen it before.
They swarm around the lights and then drop to the floor
or table, making it impossible to sit or eat near a light.
So far as is known, it occurred only one night. Many
specimens have been sent to Yungerford for determination.

CATTLE

STABLE PLY ( Stomoxys calcitrrns L. )

Nebraska M. H. Swenk (September 3): Annoyance to cattle contin-

ued daring August, but not so severely as during July.

HORN PLY (Haematobia irritans L.)

C-eneral 0. 0. Bab cock (Augast 23): The horn fly $ms not abund-

ant on the eastern slope of the Rocky Mountains. More
were observed on the waters of Clear Creek Canyon (alti-
tude ranging from 8,000 to 9,CCC feet), approximately ICO
to 150 flies to each animal. At this point most showers
occurred. In the dry areas of Slew Mexico the horn fly
was not numerous, but east of Zl Paso, Tex., in districts
where recent r^ns had occurred, the flies were observed
to be from/ 'to 3,000 per animal. Partner oast from the
Guadalupe Mountains to Sonera, where the hot area began,
and no rains had fallen, the fly was scarce.

REI3DEER

MOSQUITOES (Culex sp.)

Alaska L. J. Palmer (August) : Mosquitoes were unusually abund-

ant this season and caused considerable loss to reindeer
owners. Many fawns were killed and some grown animals.
Reindeer and caribou were so reduced in flesh that they

finally died. Some small herds '-'ere kept on feed in cor-
rals and smudges kept going day and night to save the ani-
mals from complete annihilation. Fur farmers suffered
losses and out-of-door workers were terribly annoyed and
at times forced to quit work. Farm operations were much
interfered with, as it was necessary to keep horses shut
up in barns most cf the time.

PIGEONS

PIGEON HIPP030SCID (Lynchia maura Bigot)

General F. C. Bishopp (August): This pigeon parasite has been

complained of during August by pigeon raisers in South
