OUTSTANDING ENTOMOLOGICAL FEATURES IN THE UNITED STATES FOR MARCH, 1927.
The chinch bug is reported as having started migration from winter
quarters to the wheat fields during the last week in February, in southern
Kansas. Mortality was generally low over the Kansas chinch bug belt. Eastward
the insect seems to be less abundant in winter quarters than usual. Missouri
reports serious numbers only in the counties along the western edge of the
Somewhat intense infestations of the green bug are reported from
the region north of Dallas and Fort Worth, Tex., extending from Love County
westward to Cotton County and northward to Kingfisher County in Oklahoma.
Thousands of acres of winter wheat have been destroyed by the false
wireworms around Syracuse, Kans. Damage by this insect is also reported from
Jennings and Salina, in the same State.
One of the noteworthy entomological events of the month was the
launching of the extensive control campaign against the European corn borer.
The pea aphid is appearing in threatening numbers in alfalfa fields
in parts of Oklahoma.
The green apple aphid began to hatch in the Winchester section of
Virginia on March 14, and at Blacksburg on March 23.
By March 23, the apple grain aphid was abundant in the Blacksburg
section of Virginia. It was observed in rather threatening numbers in Morgan
County, Illinois, on March 16, and eggs of this insect began hatching the
same week in central Missouri.
The first rosy apple aphid was observed in the Winchester section of
Virginia on March 18 and in the Blacksburg section on March 14.
The strawberry weevil is reported as unusually abundant and doing
serious damage in the Chadbourn section of North Carolina. The weevils began
entering the fields on March 7, and egg laying started on March 13.
The Florida flower thrips has been severely damaging beans in the
Okeechobee district of Florida.
The first adult of the boll weevil was collected from the field on
March 14 in Florida; 3.88 per cent of the adults in the hibernation cages at
Gainesville had emerged by February 28. rIo emergence has yet been observed in
Louisi6&as In the Lower Rio Grande Valley of Texas weevils were active
in January, feeding on the growth from last year's stalks.
The cotton flea -s emerging in rather large numbers about the middle of
March in the experimental hibernation quarters at the Texas Station.
The su;:,rcane borer passed the mnter much more successfully than it
did the winter of 1925-26 in the Louisiana s arcane section. Pupation in the
field began in the first week of February, and the first moths aoineared March
3. This is a month earlier than they appeared in 1926.
One of the most severe infestations by the buffalo nat ever recorded
in the State of Mississippi Tas at its height during the early p!irt of iUrch
this year. This insect was so abundant that in Yazoo County about 70 hesi of
horses and mules were killed. The outbreak extends from the Delta bacb-ard to
from 5 to 10 miles from the river.
CEREAL AND FORAGE-CROP INSECTS
F. L. Thomas (March 21): The cutworms, especially the greasy cutworm,
have been unusually injurious over a rather large area in south-
central Texas. A species, samples of which have not been received,
has been reported as damaging wheat and oats in several counties
in the northwestern part of the State.
PALE '7ESTFPJ1 CUT"ORPI (Porosagrotis orthogonia Morr.)
C. EF Sanborn (March 18): The pale western cutworm, which has been
more or less injurious in the northwestern part of the State, es-
pecially to wheat,is becoming more general in its appearance and
*less severe in attack.
HESSIAN FLY (Phytophaga destructor Say)
J. H. Bigger (March 21): Slight infestation in fall sown wheat,
but heavy infestation in volunteer wheat. Probably a great increase
in infestation by the spring brood.
L. Haseman (March .10): With our ten-year Hessian fly experiment
drawn to a close with last summer's harvest we are not continuing
as an important station project the ten or a dozen experimental
seeding plats throughout the State, and we have had little opportunity.
of making a survey since wheat harvest. However, those records
showed the Hessian fly at a very low ebb without any real danger of
the pest causing hb&m to the coming wheat crop. (March 25): There
is no indication that the pest will be of any importance on the
coming wheat crop.
CHINCH BUGT (Blissus leucorterus Say)
L. Haseman (March 10): Chinch bugs went into the winter in large
numbers in a number of counties along the western edge of the
State, through the north-central part of the State and along the
east-central portion, but the unusual rainfall during the fall and
early winter months has been very favorable for the pest. Unless
a drought develops we are not expecting any real epidemic and in
case of drought the destructive infestations will, we believe, be
confined to scattered counties or two individual farms. (March 25):
In central Missouri the bugs -were scarce in winter quarters.
J. V. McColloch (March 21): Surveys show that the chinch bugs
are very numerous in the grassland, and there has been little
mortality during the winter. migrationn to the wheat fields has
occurred in some areas. On February 22, bugs were flying in southern
GRET BUG (Tozootera graminumm Rond.)
R. W. Earned (;rch 28): About iarch 16, A. L. Hamner spent
30 minutes searching for the green bug in an oat field at
A. & 1.. College, iiss., but none were found.
L. Haseman (March 10): '7e have made no -heat survey, and the
green bug has not been reported by any growers.
C. E. Sanborn (March 18): The green bug is increasing its boundary
line of infestation. Data from both Federal and State entomolo-
gists indicate that its heaviest infestation lies in the country
north of Dallas and Fort '.orth, Tex. A great deal of small grain
has already been plowed under because of darma-ge by the green
bug. The infestation in Oklahoma lies north and -estward from
the infestation in Texas, extending from within Love County west-
ward to within Cotton County, thence northward into Kingfisher
County. Very recently parasites have been noticed. Indications
are that the ij-festation -'ill become rather severe before para-
sites can develop to such an extent as to bring it under subjection
PLAITS FALSE TIF.E7CR1A- (Eleodes opaca Say)
J. "7.IIcColloch (March 20): Reports of false 7ire-orm injury to
17heat have been received during the past two -eeks from Quinter,
Jennings, Syracuse, and Salina. At Syracuse thousands of acres
of "hceat have been destroyed. Al1 reports are from areas '-here
there -Tas little rain last fall and where much of the seed failed
EUL':, UA7 CI T 3ROFaR (Pyrausta nubilalis hbn. )
The $10,000,000 European corn borer campai-n be-n i'Trch 14.
The infested area now includes about 60,000,000 acres.
The purpose of the carnpaiga is to clean up the borer as far
as possible in the infested area and to pre-ent the serious
damage to the corn crop in Illinois, lowa, and other Corn Belt
States that -ould result from its farther spre-id. In the clean-
up, the cornstalks either will be Xthared and burned or plowed
under cleanly, care being taken not to dra,- any debris to the
surface afterwards. Corn stubble mill be destroyed with a stubble
pulverizer. All cornstalks, pieces of cornstalks, P.id corncobs
around barnyards and feed-lots will be cleaned up and burned.
The plan is to pay the farmers for work that is done over and
above their normal farming operations at a rate not to exceed
$2 per acre for field corn and not to excecc $1 per acre for
The following are the counties in `-ic' the clean-up wll1

DINGY CUT`7OPi (Feltia subaothica Haw.)
D. B. Whelan larchh 15): This cutworm has been reported both from
McCook, Redwillow County, and from St. Paul, Howard County, '.There
it was found in corn ears left in the field all winter,
D.O 'B, "7helan ((March 15}:- From hEustis, Frontier County, some
specimens of a hesperiid larva were sent, together with a portion
of corn which was badly riddled by its burro-s. Our correspondent
states that about two-thirds of the stalks were affected in this
GRAPE COLASPIS (Colas-pis brunnea Fab. )
J. H. Bigger (I'March 21): Severe losses expected to corn on red
clover land. Wet season might minimize this darnae. Large numbers
of larvae -ent into hibernation successfully.
PFA APHID (Illinoia pisi Kalt.)
C. S. Rude (March 18): This pest is very numerous in Roger Mills,
Woodward, and 7oods Counties. As yet the damage is not severe.
C. E. Sanborn (March 18): There is a rather serious infestation
of the pea aphid on alfalfa in Woodward, Ellis, Toods, and Roger
Mills Counties of this State. This pest is not ordinarily con-
trolled in Oklahoma by any insect parasite but is generally quite
suddenly controlled by a disease. The disease is not yet prevalent,
It generally comes after several 'eehs of warm "-eather. I might
add that the pea aphid also attacks sweet clover in this State
to a very marked extent although the latter has never been der:i"ged
beyond recovery, In many instances alfalfa has been damaged be-
J. R. Horton ('i'%rch 19): Unusually abundant in 7ood-ard County,
although I have not seen specimens, I am quite sur0 it is the
1--L -'ZT.'IL (Ph-rto.io.us nigrirostris Fab.)
J. H. Bi Per (Ilarch 21): Severe damage to clover buds and seed crop
expected this spring. Large numbers of adults survived the -inter,
CLOVFR LEAF -ES7lL (Hvprr- punctata Fab.)
J. H. Bier (March 21): Little severe damage expected! this season.
?e' survived severe fall "-.-:ther and rains. Some slight damage if
we have very favorable weather.
FRUIT I S3ECT S
APPLE APHID (Anhis ,ori DeG.)
Mi s s ouri
T. J. Schoene (Uavrch 23): According to Dr. 7. S. Hough, the green
aphids bean to hatch in the 1inchsE-ter section on March 14. L.
R. Cagle reports that the first green aphids rere observed at
Blacksburg on March 23. The green aphids are abundant.
R. '7. HIrned (March 30): Attacking satsurma at ioss Point, Miss.
Determinations made by A. L, Hamner.
APPLE GRAIN APHID (Rhonoalosiphum prunifoliae Fitch)
7. J. Schoene (March 23): Ot aphids are abunl'int,
J. H. Bigger (March 21): Barring very unfavorable 'eathlier, severe
damage is probable in the early season. Observed in large numbers
first in Morgan County >?'rch 16.
L. Haseman (March 25): :.s bejni hatchiai March 15 to 80. :7uch
more abundant than last year at the same time though in central
Missouri not so abuna.it as during severe e : .Aeics.
ROSY APPLE APHID (Alu nihis rasous 3Ter)
W. J. Schoene (Iarch :5): Accor'i.-.: to Dr, 7. S. .o the
first rosy aphids were obr.-V? i; the "i.ic'>.ester section i:[rch

Blacksbur- on Lnrch 14. The ro-y ; phic ,r? rese-.t in very small
CODLING MOTH (Carpocapsa pomronella L.)
J. H. Bigger (Iarch 21): Severe damage expected. Low winter
mortality. Large numbers in hibernation.
EAST71-" T: CATEYPILLAR (Malacosoma americana Fab.)
A* I. Bourne (March 16): It appears that the tent caterpillars
are fully as numerous as a year ago, which will mean a heavy
infestation throughout practically the entire State. Campaigns
have been started, interesting boys and girls clubs, boy scouts,
etc., to collect and destroy the overwintering egg masses, and
the program stimulated by a few well chosen prizes offered
by various agricultural societies has a-akened a very gratifying
response on the part of the boys and girls. Alreaiy many thous-
ands of egg masses have been collected and destroyed. It is
planned to continue this work clear up to the time of the hatch-
ing of the eggs. Just -hat effect this 1-rill have upon the
later infestation is of course merely a matter of conjecture.
In fact, we can not be sure that it -ill exert any great amount
of influence upon the heavy infestation which is state-ide. "7e
-ill be able, in the course of another month, to report to you
more definitely on this point.
7. J. Baerg (March 19): The caterpillars hatched about four or
five days ago. The infestation will probably be moderate.
FRUIT T7.1 LEA.F ROLLER (Archips arayrospila Talker)
R. L. Webster (March 29): Examination of leaf roller egg masses
by Mr. Spuler in Spokane Valley showed that there Tas no
damage or any severe outbreak in 1927, Not enough live ezs
found to warrant continuation of oil spray rash there.
SPRIITUC- CANKIR "70'n: (Paleacrita vernata Peck. )
H. IT. -orthley (Iarch 21): Moderate numbers seen on road from
Butler to Greensburg on the evening of March 11. Observed on
window panes of hotel in Franklin (Venango County), ikirch 17.
L. Haseman (March 25): Male moths attracted to lights TIarch
1 to 15. An occasional specimen was observed.
ROSE LEAFHOP3ER ( 2poa rose L.)
L. Haseman (March 25): Very abundant though still in their
winter harbors. Observed, however, in blue grass harbors !-arch
1 to 10.
BUFFALO TR EHOFFER (Ceresa bubalus Fab.)
D. B. 'Thelan (March 15): A portion of a young apple tree
TATE PLANT BOARD
coverrdd with old injury by this insect ras received.
SA' JOSE SCALE (Aspidiotus perniciosus Comst.)
Massachusetts A. I. Bourne (.1-irch 16): The San Jose scale, whichh for a few
years seemed to be incr^-^ing to some extent, has v3ry largely
subsided as a pest of prime importance. whilee it is still
present, it is not causing any anxiety. Apm:rently a very general
use of oil sprays made necessary by the rapid sproa)- of the
European red m-ite throughout as's-ichusetts lhas automatically
controlled the situation, as re :ards the San Jose scale.
L. Haseman (Iarch 10): This pest continues to be at a lo7 ebb
rith a tendency through central :.:issouri to pick up in numbers.
Our fruit gro-ers have it completely under control in all
commercial orchard centers.
OYSTEP-SHELL SCALE (Leidorsahes ulmi L.)
D. B. islan archh 15): A badly infested specimen of a nest
on aponle bark was sent from Ho'ells, Colfax County.
ZU-?':P3AN R.- MITE (Paratetranychus pilosus Can. Fa:-z.)
A. I. Bourne (:''rch 16): Th-ere seems to be a heavy infestation
of the European red mite throu.>.out practically all sections
of the State. This, of course, it based on the evidence of the
overwintering eggs. Although :rsaavy gro-ers secured .-o? control
by the use of oil sprays a year ago, there s-r.s to have been
sufficient increase over the State as a -hole so that reinfes-
tation took place quite rapidly.
A LEAF BLISTTR ;uL:E (Eriophyes rwri Pgst.)
T. D. Urbahns (in'rch 22): The blister mite Eriophyes 2TLi
'-is active under the bud scales, and r--s were being deposited
on pear at Penryn. (lu-irch 29): The pe:-r leaf blister mite has
caused considerable d:'i -ne to pear buds in the ?Tcramento,
ITa_'a ,and Suisun Counties on account of the mild -.inte'. weat'.-er.
The mites continued active under the bud scales. SprA.rina in
full cluster bud is just be_.,in.
RU-rsUY PLUM APHID (Hvsteroneura setariae Thos.)
R. '7. Harned (:' rch 28): The first complaint in re-rd to the
Southern plum or rusty bro-n aphis this ''--r accomuanied by
specimens came from the property of G. C. Coats at Meridian,
Miss., on March 22. Plum trees were reported to be heavily
infested. (Determination by A. L. Hamner). (March 30): Attacking
plum at Picayune, i'iss.
TESTEP2R PISTOL CASE BEAthR (Coleophora sacramenta Heinrich)
California T. D, Urbahns (i.;arch 22): On March 4 the pistol case bearer,
Coleophora sacramenta, was observed migrating from tuigs to the
buds and beginning its feeding.
GRAPE LEAFHOPPER (Erythroneura comes Say)
Nissouri L. Haseman (March 25): Very abundant though still in their "-inter
harbors. Observed, however, in blue grass harbors March 1 to 10.
C IT US AND SUBTROPICAL FRUITS
SPIRA2A APHID (Aphis spiraecola Patch)
Florida J. R. Watson (LI4rch 19): Aphis spiraecola Patch has not yet
recovered from the freezes of January which killed all tender
growth on the citrus trees. They are, ho-'ever, rapidly increasing
in numbers and, unless checked by their fungus disease, indications
point to considerable damage later.
D2STRUCTOR SCALE (Aspidiotus destructor Signoret)
Haiti G. N. Wolcott (L.Irch 11): A very serious outbreak of Aspidiotus
destructor, occurred at Cayes, Haiti, on coconut palms. This was
reported several months ago by Dr. H. D. Barker as a dying of
the palms; and, when recently investigted, the yellowing of the
fronds and dying of some of the trees was found to be entirely
due to a heavy infestation by this scale. Few parasites or pDrelators,
which are usually present, 'ere noted on these palms. The scale
had also spread to banana and :Ianmea americana trees.
T'x-s F. L. Thomas (February 17): White fly pupae have been received
from San Benito. This is the first information of the occurrence
of this insect in the Valley that has come to my attention.
I SCELLAITEC TJS FEEDERS
CUT WOR M-S (Noctuidae)
C. E. Sanborn (March 1S): Cutworms, especially comrjon garden
cutworms, are being reported as more prevalent this spring than
G. H. Bradley (March 26); A species of cutworm has been very
bad in my garden this past month, destroying peas, lettuce,
spinach, and tomatoes. This garden was all plantqt. t6 corn
last :,ear and was kept fairly well cultivated. One of my neigh-
bors who had some cabbage planted reports that cut7'orms destroyed.
every plant that he had.
SCUThIR2J GREEN STINK BUG (ITeara viridula L. )
R. W. Harned (March 30): Although many complaints in regard to
the southern green plant bug have been received during the past
few weeks, only one lot of specimens has been sent to this office.
These specimens came from Peoria in Amite County on March 21.
J. R. Watson (March 19): Aphids have been unusually abundant
on truck crops during the past few weeks. mustardd turnips,
radishes, and peas have suffered severely, cabbages and lettuce
to a lesser extent.
WESTERN SPOTTED CUCU"MER BEETLE (Diabrotica soror Lec.)
T. D. Urbahns (March 22); Has been active in fields of vegeta-
blesgardens on warm days throughout the winter in the Santa
TURNIP W7EEVIL (Listroderes obliquus Gyll.)
Lou i ai.n'
R. W. Earned (March 30): Adult specimens of Listrodercs obli-
quus were received from Laurel, on March 23, where they were
reported as feeding upon collard plants.
T. D. Urbahns (March 22): The Australian tomato weevil was
active in the various larval staxges throughout the winter
months in the San 7rancisco Bay region on turnips, spinach,
TURITIP APHID (Rhopalosiphum pReudobrascvicac Davis)
R. W. Earned (March 30): Attacking turnips at Yazoo City and
An-uilla. Determination made by A. L. Hamnenr.
W. E. Hinds March l14); Exceedingly abundant on m.?ny fpod plants
up to the end of February but heavy rains and temperatures down to
freezing have reduced their numbers materially.
RED SPIDER (Tetr-F. ",us bimaculatus Harv.)
"T'. E. Hinds (March l14): Red spiders were exceec'in-ly abundant
on many food plants up to the end of February but heavy rains
and temperatures dom to freezing have reduced their numbers
PEPFER WEEVIL (anthonomus eurcnii Cano.)
R. R. McLean (March 25): Pepper weevil, Anthonomus eugenii Cano,.
is doing considerable damage in several fields around Vista and
Bonsall in San Diego County.
C P tIn AGE
C.2B&E A4PHID (Brevicoryne brassicae L.)
R. Earned (March 30): Attacking cabbage and collard at
Hazlehurst and Yazoo City. Determination made by A. L. Hamner.
HARLECUII: BUG (?:ur- intia histrionica HTAt.)
R. 7. Harned (March 30): The harlequin cabb-'-ge bug seems to be
quite abundant in all parts of the State at the present time.
Specimens have been received during the last few days from Bel-
zoni, Collins, Peoria, and Yazoo City. "Vintcr turnips seem to
be the crop most heavily attacked at this season. A few com-
plaints are received in regard to these insects on collards and
POTATO LEAFHOPPER (E-ipo&sca fabae Harris)
L. Haseman (March 25): Very abundant though still in their
winter harbors. Observed, however, in blue grass harbors
FIELD CRICKETS (Gryllus assimilis Fab.)
R. 'T. Harned (March 30): Complaints have been received recent-
ly from Laurel, Picayune, and :igZ-inc, in regard to serious dam-
age caused to strawberries by crickets. (Specimens from Laurel
were determined by J. M. Langston as Gryllus assimilis Fab.)
vi. E. Hinds (March 14): Crickets are reported in several local-
ities as injuring the fruit of strawberries where the plants.
have been mulched heavily during the winter.

ST-..1-27RY ";:VIL ('nthonc-.us signatus Say)
k,. A. Thomas (March 21): This insect is unusually abundant at
Chad'bourn this season and is doing serious dap-^e to fields of
berries -ihere no control measures have been employed. The
weevils began entering the fields on :arch 7 and fed he:.vily on
developing buds before beginning e.; deposition on :arch 13.
They are now generally distributed on most farms on the zsecl
tion. T'.-'ertyone active devilss were collected on a single
plant early last week.
...... 3UGS (OY!SCIDP3)
R. .. Harned (March 30): On March 24 Cointy -._eit Jas. H. Frice
Pascagoula, -r.ote as follows: 'These pill-bugs or sow-u-s are
literally eating up our strawberries. One lady told -5this
morning that she had been able to -c-. but one strawberry for
over a week. I have a few myself and it is very '-.ar'. to .-ct a
berry without a hole eaten in it and most of them arI- from one-

from hibernation ca';es at Baton Rouge.
Missouri L. Hazem-ai (March 10): This pest attracted no attention on our
southern cotton gro'in farfis the past two or three seasons.
Texas 7. L. Thomas (March 21): Boll v weevils were active in January
in the hibernation cages. They have been feeding on cotton nihich
is growing from last year's stalks in the Lower Rio Grande Valley.
I understand that much of this cotton v-;ill be left to grow a crop
this year, and as a result we are expecting much complaint from
boll weevil injury.
CCOTTO FLEA (Psallus ser iatus Reut.)
Texas F. L. Thomas (March 15): The number of cotton flea hoppers rhich
have emerged or hatched from each lot of 100 plants, from first
emergence up to above date, inclusive, is given belo-7.
College Station G-oatweed ............ 796 ........ 26.

Date of first emergence at College Station: February 16. The
much larger number of cotton flea hopp-ers emerging from goat-eed
at College Station in 1927 is not considered as especially signi-
ficant at this time, but is probably a result of more favorable
weather conditions for hatching of the eggs.

'". :-2...s (I:arch 14): 'ith reard to the sugarcane borer hiber-
nation, we have found during the past few weeks a very large num-
ber of full-gro'.n larvae in the stalks of cane, corn, etc. The
survival is ve^ r;- much hea-'rier than it was a year ,...o. -iapation
began in the field during the first .eek of February ?,n the
first moth emerging out of doors was taken in our ca-es '.arch -3.
This is at least a month earlier than moths became active here in
1926. This indicates a strong probability of six generations of
sv.. arcane borers this season where re had only five in 192S.

in .c'/-e.7.er, 1926, as Lecaniodiaspis sp., prob,-bly ciltitis
Cockerell, by Harold ::crrison of the bureau of Ertoo.lo-., -as
been repeatedly co-Il gained of during J-:n-jr;--, 1?7, as -ell as
during the fall of 192oS, by residents of Grand I zli,--:r.Jn, Hall
County. Our att^ntie: 'as first dravn to this inf?..tion by
the Hall County agricultural agent in 2ept ..er, 1925. .1M,
hackberry, and locust trees are the ones chiefly affected, and
many of these have been killed during 1926 because of the severe
attack of this scale.

R. 7. Harned (February 26): '.e are -avir. a --rious outbreak:
of the buffalo gnats in parts of iissi.:.ippi. (ic-rch 28): On
March 5, Pr. J. F. Barnett, a well--:o'7n veterinarian in Yazoo
County, rote as follows: ".ie have had the buffalo gnat h.-re
for several days. I had more calls than I could fill for t-.o
or three days until I could -L't the owners of stocks to spray
and -rease the animals. They thought the animals had colic and
in a few- hours the animals rere in such condition that I could
do them no good. At first they roll and sfh'at and act like they
have colic. Some swell and at first there is a little rise in
te,-ir.-.rature, but in two or three hours the heart is affected
and the pulse can not be felt. They get in a stupor or coma,
run against objects, and soon fall dead. Most of the animals
were dead or past doing anything for them I), the time I could
fiet to them. I was able to save suite a number where I reached
them before the pulse was too w-eak and the temperature subnormrnal.
I used rawv linseed oil and stimulants such as carbonate of ammo-
nia, aromatic spirits of ammonia, and c'zmohor in --.i.key.
Durini'-- the cold sn&-p the ;-:-t:ts disaprea-cd, but now that it is
v.arm c:.-i-tin they are plentiful in places. It seems that the
wind carries them and th-y apncar and diF-apre.. Since the peo-
ple are spraying and greasing no cattle a-u dying. Some frmners
usu r.'k-ers. I have been practicing here for 215 .'ears and I
believe they were worse this tirr.o than ever before. Some 50 to
75 head died in this county from gnats. Hules and horses are af-
fected more than cattle and other animals."
Chesley Hines, Inspector for the State Plant Bcacrd --ith head-
quarters at Yazoo City, nrade some investigation in record to the
buffalo gnat and reported as follows: "Alth'ou.-h the ,-nats -ere
mighty bad in the delta proper, thr- ras a greater loss of
mules and horses in the locality of Eden west of Zeiglersville
which is from 5 to 10 miles from the river and in the hills. In
this particular locality, I have learned from reliable sources
that 25 head of mules and horses diel. One man in this part of
the county lost seven out of the 8 males he had. Another man
living about 4 miles east of Yazoo City in the hills lost the
only tvwo mules he h:-i. I would say that the total mber of
mules and horses lost in the county would be around 65 or 70."
All kinds of stock serrio to be attnckoei by the gnat, au't I
have not hc-trd of any dy:i._- except mules and horses and more
mules than horses. I noticed -'-'veral cows with their udiiders
cover-'d vith blood cau'--i from the bites of the .ats.
I have made speci-l inquiry as to the condition of the ani-
mals that succumb9 from th-. bite of the .aats and from all
indications the healthy ones yere affected as severely as the
poorly cared for. Th,- .7nats attack the arnima.ls under the
belly, as -.ell ac alo-iv the le--r. Some few have advanced the
idea that the gnats get into the nose and ears of the .iirL.ls
and kill them that way, but I have been unable to find them
around these parts to amount to anything. They undoubtedly
poison the animals and at the same time weaken them by suck-
ing the blood. as but few if any die after the first few days
of the outbreak, it looks as though the animals may become im-
mune to the poison to a certain extent after t"ey get used to
The people are using various concoctions to keep the gnats
off, either buying them prepared or making them themselves. All
use some kind of a mixture of oil and tar. They use various
stimulant remedies after the mules have gotten down. I was in
the delta yesterday and the gnats were as t'hiLc' as they were
before the cold spell. I was in imdison Thursday and inquired
about them. They had not noticed any there yet.
On iarch 28 another correspondent at Webb in Tallahatchie
County wrote that the buffalo gnats were "getting bad in this

AN ANT (Camponotus car",e subsp. rasilis -.heeler)
R. 7. Earned (.ylrch 30): This ant has been received from
Biloxi, Fascagoula, and Starkville, where it was found infest-
ing houses. It normally nests outdoors in cavities in the
branches of trees or in insect galls. At St-rkville, the en-
trance to their nests '-ns several sm-ill cr,.cks aLround the win-
dow casing of a bed room. The workers have been noted in this
house since last summer. At the time the house was visited,
alate males and females v'ere appe-ring in large numbers on the
window sills. The owner stated that the c.nts had given no
trouble around the dining room or kitchen. Specimens found in
other houses in this vicinity were noted to feed on sugar and
to forage most conmonly in dark places. (Determination made
