FO?. J,'7UJ1r AITD Fp2(uMY, 1931.

In introducing Voluie 11 of the Insect Fest Suarveo Bulletin, we
v3.sh to express the gratitude .'_hic: the Survey feels for the nan;-
c:r-.,-endations received- fron its readers on th1 last ary u'..e.r.
The quality of this number, and, in fact, of the entire SarvCe 2ulle-
tin, is to a very lar+e extent attributable to the '-icncre?.si cooper-
ation whichh ',e arc receivin- froa- our collmbcr .torr. Prob.,l" the
most influential factor in this incroasc effici:o is t.e a.pPreci-
ation by the entomologists of the States of the value of State S"...y.s.
Each year additional States incluc th is ohfsc of ,o as : r.:jor
project, and with each State Suirrey set up, th1 eral Insect ret
Survey's picture of the entoniolo-ical conditions i' t'hat State advances
.:-.'.- t e r i all".
The Survey i .shcs also at this tireo to re-nind its collaorntors
tl.at it is now in position to assist th--0 :ateriallC- in vorii_ up
_u.rap-.ica! distribution nd lists of hot plant ad of prasitc of
individual pests. It can not, ho'-'evcr, v.n.ertahe the preparation of
comprehensive lists of isects, althoeh its files a.re 0al's ope- to
research ,.orcr io find it possible to visit 0shin-ton. 'About 20
re'v,:ests for infon.ational service v:ere filed ..'-- the past "ear.

Quite naturally, 'hen such -a l r7 s of i-fo tion f:. so
,many and v.ried sources is received, w.ist.'es in deter.inntio: ,nd
interpretation rill occur. The Su-arve,- invites its reacers to critinisC
anr feature of the material that it :-ublises ancd ures th: t send
in co"r,,::;tions ?ro::'.tly in order t.at .. ::staes ",- not ire':Ain in the
per:.e:t records of the Surve-, but a.y be co-rected_ i-n ml.cqcr'ent
...uri.'bers of the Bulletin.

The very rc:...ar2'.ble drou.;ht that prev)ild over a l -r *c art of
the country last year will un_,doubtcl.2 have a arhed effect on the
ab-undan..ce of nany insects. The vzr-- :wild -,inter th't :-'as pr-vailcd
over an equally lar- re-ion :ill also pr obaly be reflected in insect
bu-'._:.co. Our collaborators should strain every effort ti Car t









give the Survey as complete a picture as possible of the relative abundnce
of the various insects of their respective territories.

DaLring the very warr weather of late January and. early Fobruary,
reports were received from Missouri 3n South D2:ota. of emer,-once of
grasshoppers. It was at first believe' that tiis was Drecocious hatching,
but later evidence seems to indic.Ate that it was merely the emor-cnce from
hibernation of such specic.s of .rasshoppers as spend the winter in the
early nynphal stares.

This sa.e warm weather resuIJted in reports of the appIearace of cut-
worms in Missouri, and we also have a report of damae to strawberry "buds
by cutworms late in February on Bainbrid-e Isl.and in Washin]ton State.

An interesting observation of the successful hibernation of the
pupae of the corn eoar worn at Coluibia, Mo., has been received. These
pupae were alive when the report was made, in the last woT of February.

The sugarcane borer appears to have passed the winter in very !Tood
condition in Louisiana, though the population that entered hibernation
is reported as having been small.

E-.zs of the rosy apple aphid seem to be prevalent enough in Pennsyl-
vania to indicate trouble, while in southern Vir-'inia they are so scarce
that the entomologists are recomm-.iendin- omittin; the aphid treatment in
early s r?;s.

The San Jose scale still sees to be on the increase along the
Atlantic seaboard from Pennsylvania to Georgia a.nd westward over the Gulf
region.

Reports of very successful hibernation of the codlin- moth have been
received from tihe cw land, Middle Atlantic, South Atlantic, and tho
southern part of the ?.mst Central States.

The vegetable weevil has been reported from practically the entire
infested territory as affection winter tr.ucl crops.

The spotted cucm_.ber beetle is reported as doin;, more or less d0-mge
in the Gulf region. This condition, however, is not unusual.

The banded cucumber beetle is reported as quite -enerally distributed
over Florida. Although known for several -ears front the western part of
the State, it is a new pest on the peninsula.

The western spotted cucumber beetle started leaving winter quarters
during late Janaary in Oregon.

Florida

Mississippi


J. R. Watson (February 24): Grasshoppers are moderately
abundant in Florida.

Washington Evening Star (February 1): "Hopping insects
were brought in from the country near Marshall yesterday by
L. D. Murrell, banker. His assertion that they were grass-
hoppers Was supported by most local entomology experts, who
said never before had the insects been observed in January."

L. Haseman (February 26): During the noon hour today at
Columbia, with the temperature I should say in the 60's and
with a bright warm sun, I did some scouting for freshly
hatched grasshopper nymphs, covering a distance of something
like a mile in pastures, along rocky hillsides, meadows and
truck patch, but was unable to locate a single individual.
I am rather of the opinion the recent reports must either
have referred to early hatching on warm south slopes, or else
they may have referred to the species which may winter with
us in the partly grown nymph stage. I failed to find any of
these partly grown specimens of nymphs either.

H. C. Severin (February 19): It has been claimed by some
of our people living in the western part of the State where
grasshopper outbreaks were most serious last year that grass-
hopper eggs have already hatched. This may be true, but I
doubt it very much, for we have quite a number of species of
grasshoppers that hibernate in a nymphal stage and it is prob-
ably such nymphs that the reporters saw.

Henry Dietrich (February 25): Grasshoppers were moderately
abundant in George County until the middle of December, 1930.

C. D. Lebert (February 25): Melanoplus spp. and Schistocerca
spp. are scarce.

CUTWORMS (No c t uidae)

J. R. Watson (February 24): Cutworms are scarce; less than
usual.

L. Haseman (February 26): Partly grown cutwolrms are out
at Columbia.

I' H. Dietrich (February 25): Cutworms were bad on turnips
in George County last November but have been neglibible all
winter.








'exas F. L.'Thomas (_february 27'): As yet we have received
no complaints of cutworms.

xrizona C. D. Lebert (Febrary 25):" A-otis ypsilon Rott.is
moderately abundant in Salt River Valley.

'ashington ,m. W. Baker (February 26): Japanese strawberry grc'.ers
on 'Bainbridge Island report two kinds of cutworms as working
on the buds of strawberries at this time and state that they
have never observed them working this early during previous
seasons. T,.o of the growers have promised to send in mate-
rial for determination.

IJJ.7ORMS (Elateridae)

:ansas H. R. 'ryson (February 20): 77ireWorms became active near
the surface at .z'.httan unusually early this year.

7HIITE GRUBS (.hyllohaga spp.)

:ansas H. R. Bryson (February 20): Owing to the recent high tem-
peratures, white grubs are very close to -the- surface at
Manhattan.


C R E A L A 1 D F RAGE C R 0 P I- IT S E C T S



HZSSIA.: FLY (Phytcohaga destructor Say)

'lissouri L. Haseman (February 23): The Hessiarn fly infestation is
more or less scattered similar to last 'year, but thus far
this pest has survived the winter in fine +shape. Some sam-
ples taken earlier in the winter showed a vEry high per-
centage of parasitism, while others near Columbia show little
or none.
CORIT

CHIi:CH BUJG (Blissus lcico-nterus Say),

[issouri L. Hassr7-..n (February 23): The weather up until the last
few weeks has been ileal for chinch bugs, as we had little
moisture prior to Febr';:.ry. The present coot rains are not
so favorable for the bugs, however.

kansas H. R, Bryson (February 20): There are very few chinch
jbus to go into hibernation at MY.inhattmn this winter. Large
numbers went into winter quarters in southern Kansas, but
effective burning in. a nuimb,-r of counties may reduce the
population considerably. .... I

L. Haseman (February. 23): A plant in my garden set aside
for corn ear worm studies shows that the pupae have survived.
the winter, so,?'alnost perfectly. Of 8 pupae dug up on
February 8, 7 were perfect, one apparently having been killed
by a fungus. Furthermore, these' were only on the average
about 4 inches below the surface of the ground, each with its
characteristic exit: hole, which I noted in this case ran
almost vertical, rather than sloping as it is usually de-
scribed.

SPOTTED 'CUCUPBR I.TLE (Diabrotica duodecimpunctata Fab.)

S J. R. Vatson (February 24): Th'e spotted cucumber beetle is
1 es s abundant than usual.


J. M. Robinson (.February 27).:., The spotted cucumber beetle
is moderately abundant on lettuce, turnips and legumes, at
Auburn and Fairhope.

V.7. E. Hinds (February 25): Diabrotica duodecimpunctata
are flying actively and appear. to be present in at least
average numbers. -

K. L. Cockcrhhan (Febr-iary 1): On TFebruary 1, when spray-
ing Satsuma orange trees at Biloxi, these beetles were
observed'to fly out of the trees in great numbers as the
spray -ist struck the foliage. The beetles were evidently
feeding to some extent on the more or less tender leaves.
These beetles have been very plentiful in this section all
winter, being noted on various winter truck crops. They
have appeared more numerous than usual.

H. Dietrich (7'Cjruary'25): The spotted cucumber beetle
has been moderately abundant on turnips at Lucedale all
winter.

SU^f RC 3I 02R (Diatraca saccharalis Fab.)
i
WV. E. Hinds (February 25): The hibernation of the sugar-
cane borer appears to have been quite successful for the
comparatively s'-tll borer population entering hibernation.
G-eneral observations indicate approximately 50 per cent of
the hibernating borer larvae alive up to this time. Vith
a very mild winter and an early spring it will likely give.
opportunity for an extra generation of 'borers to develop
during the following season. '

FRUIT INSECTS
APPLE

AFHIDS (Aphiidac)
H. E. Hodgkiss (Februa.ry 24): Sg.- of the rosy apple
aphid (Anuraphis roseus Baker) .:--oar to be well distributed
on the blossom spurs over the trees and very many on water
sprouts. This condition is similar to that which occurred
in the fall of 1929 and which indicated the rosy cphid out-
break of 1930. I m looking for an unusual aburnd.rnce of this
aphid this spring on account of these conditions.

M. P. Jones (!.-,rch 2): Thile on a trip to Blacksburg,
February 29, we examined an orchard near the station. .7e
found that aphid c n were so scarce that nicotine will be
omitted from the spray this spring. There was no sign of
the ec.'s hatching.

SSCALES (Coccidae)

H. C. Severin (February 19): The scale insects have
passed the winter very successfully.

R. 3. Deen (February 25): Scale insects on poach and
apple trees have been observed in very large numbers at
Tupelo. A'pprently a very large nrambr passed the -ild
winter and an eno.r.ous number of trees will be injured and
killed. whore proper spraying is not practiced.

W. V. B!aker (January and Febr-jary): The young of
L ecnnium sp. are very numerous on fruit trees and many
native shrubs around PIuyllup, S. r.ncr, Tacoma, Fairfax, and
Eatonville, vhile at Bellevue, vbcre they were very abundant
last year scales are rather sca.rce. None were found while
a number of trees and ;native shrubs on Bainbridge Island
were being cxq-ined.

SAN JOS3 SCEL (Asnidiotus perniciosus Comst.)

H. E. Hodk'iss (February 24): The San. Jose scale is vern
more abundant than v',as anticipttcd and in the Cumberland
Valley rLegion some orchards are in as bad condition as
orchards were in the first years of the San Jose scale out-
breok,










Georgia


Florida


Mississippi

C. H, Alden ( ebrary 19): -io San Jose scale is scarce
at Cornelia. Moderately. -b -idv-:nt at Thomaston, where
crawlers were found in orchards.

Oliver I. Snapp (January 20): The percentage of live
San Jose scales at Fort Valley ,.on peach trees is some-
what higher this winter than usual. This may be due to
absence of low temperatures so far this winter.- The average
percentage of live scale on peach trees oil January 6, 1931,
was fOund to be 91.6. The average percentage on January
15, 1030, was 84.9. On December 1, 1928 it was 63. On
December 6, 1927,it was 79.3' And on January 18, 1927,
was 75.

J.'-R. Watson (February 24): The San Jose scale is moder-
ately abundant.

H. Dietrich (February 25): The San Jose scale is plentiful
on peach, pear, and rose in George, Greene, and Perry Coun-
ties. It has also been found killing ornamental laurel at
Lucedale.

J. F. Kislanko (February 26): The Sran Jose scale is
killing some of the fruit trees in the vicinity of Wiggins.

R. Z. Pepper (February 26): There is quite an abundance
of San Jose scale showing up in the peach orchards near
Yazoo City.

S. Lockwood (February 26): Investigations made during the
month have shown that San Jose scale will in all probabili-
ties cause some trouble to peaches in the upper San Joaquin
Valley this year. They seem to be fairly abundant. In a
few orchards incrustations of some twigs has occurred,
though only in a few.


CODLING 70TTT (Carpocaosa pomonel1a L.)


New Hampshire


Pennsylvania





Georgia


Missouri


P. R. Lowry (February): Hibernating larvae appear in
about usual numbers in southeastern New Hampshire.

.H. E. Hodgkiss (February 24): The mortality of codling-
moth larvae.-is difficult to estimate, but there is no
reason to expect that the percentage of infestation will be
sma-ll as the number of larvae going into winter was unusually
large.

C. H. Alden (February 19): Large numicrs of hibernating
larvae were found in orchards at Cornelia.

L. Hasemen (February 23): We are carrying through an
unusually large population of the codling moth, particularly

D. C. Mote (FEbr .ry 24): No codling foths have pupated
as yet in the region of Corvallis.

`TrI CAT3PILL.ARS (Mlnco Soma ,pp.)

W. W. Ba7-er (Jan-uary nnd Febr :-ry): The egg maassos of
two caterpillars, Malacosona disitria Hbn. a-nd U. -oluvialis
Dyar, are very scarce on fruit trees and other deciduous
trees this season. Thile ...hin observations at P-Oet,
Fuyallup, Suzncr, and Bellevue, and on 3ainbrid c Island
not a single egg -aass was foe'nd where during the pars three
seasons they were abmundat, except that during the v.irer
of 1939-30 the c - of 'luvialis were rather scarce.

Florida


California


J. R. Watson (Ftc",:'-'ry 24): The green citrus aphid is very
scarce, although one occasionally meets a tree with a heavy
inifestation. This is undoubtedly due to the cold weather
causing the citrus trees to be thoroughly dormant without new
growth to support aphids. With the possible exception of
tangerines, which are al'^.ys late in putting out their growth,
it does not seem at all probable that the aphid will do much
damage this spring.

H. T. Fernald (Februar0 24): Aphis spiraecola probably
just appearing on opening' citrus leaf buds at-Orlando. It is
too soon to judge abundance.

I"SECT CO:T.ITICITS I1T PRTO RICO -J?.I:-3 T: FISCAL YZ-R -Z_,D ju:-'E 30,1930.
. ID. Leonard
Insular Experiment Station, Rio Piedras, Porto Rico.



The sngarcane borer (Diatraea -ralis ab.) is al more
serious on the south coast than elsewhere on the Island. According to
Mr. Pedor Richardson, cane tec-_olo.ist at the Insular Ex-periment
Station for the past several Tyears,tis less injurious than it has been
for "ears.

The sugarcane root caterpillar (PF'-r'oradix sacci.ari Sein), according
to Mr. Sein, is generally distributed throughout the sugarcane-growing
sections of the Island and doing considerable damage in the azregatc.

SConscensus of opinion is that white -ribs (P-llopHaga spp. ) have
been less of a factor during the past fe-w ,ears on sm.garcane t.an
formerly. Daring this past eair they ,:!er: some-.czat more abundant and
injurious on the north coast but about as injurious as usual on the
south coast.

The sugar compan-y at Caauas reported considerable da-age by the
change (Scapteriscus vicirns Scud.), especially on the more sandy t-'pes
of soil. It also did considerable darnagce in Ba3mraxon: -- Aguas Buenas.
In both the above cases the da; e was to sugarcane. This insect is
most injurious to sugarca.ne in the tobacco zone and the T:r?.:o Valley,
including H.uricao, Las Piedras, and Juncos. It was also reported as
severely di'ing torr.tous in Gazu..s on the more sndc' soils. The ch_-n,-aa
(Scapteri sous vicinus Scud.) did considerable dnaga in Februa-iry and
March to peppers being 7rown for canning purposes at Rio Piedras.

In May a considerable i nfestation of the yello' cane aphid (Sipha
flava Forbes) started at Ag'cirrc but ladybeetles were reported to have
cneched it before any undue mnornt of dama;e result ...d. Often rather
injurious during the begin;nin- of the smnrrcr, epecially during the dry
Fp~lls and in the southwestern p -rt off the Island. Apparently th e past
year was about normal for this pest atta.

TOBACCO

Horn worms (Protoparce se-ta Joh. var. jnrice-sis Butl.) were re-
ported by J. A. B. :Tolla as doing severe d'c.uage to tobacco during part
of the year at Cagas.

The potato flea beetle (2pitri4 cuciuncris L. ) has been generally
present in both sc:.d c:1. and in the fields of tobacco but not especially
injurious except on no-v'ly set plants in the Ca.yey-Aibonito district.

Both tha large tobacco suckfly (Dicyphus lridus Gibson) and the
s.2aller one (D. prasinus Gibson) were observed in m :v, tobacco fields






-34-


but apparently they are not very injurious. In M1arch, 1930, the larger
tobacco suc'-fly caused considerable trouble by destroying the buds and
blossoms in a large cross-pollination test in a field in Caguas.

Cutworms (:Toctuidae) have been generallyy present both in tobacco
seedbeds and in the field but not especially 'injurious, except on newly
set plants in the Cayey-Aibonito district.

CITRUS

The Florida red scale (Chrysomphalus ficus AshM.) and the purple
scale (Lepidosaphes beckii 17ewm. ) were about as injurious to citrus as
usual.

".thite grubs (Phyllopha spp.) were occasionally reported as injurious
to young citrus trees.

Reports have been received of a little damage'to citrus by the vaquita
(Diaprepes spengleri L..)

A red spicer (Totranychus sp.) was more injurious on citrus than
usual during the excessiveJly dry spring and summer.

The citrus rust mite (Plyll]:ocoptes oleivorus Ashm.) was more injurious
to citrus than usual.during the excessively dry spring and summer.

OCOC:'T

The rhinoceros beetle (Stratzsgu q-uadrifoveatus P. de B.) was
destructive in almost all coconut p! 'ntings, but apparently more injurious
along the eastern and, o :rn coasts. The Extension Division has been
conducting a clean-up c-mnpaign against this pest, which has been more
injurious since the hurricane of 1928 than formerly.

CASSAVA

A r?.re root weevil, Coelosternus sulcatulus Boehm., was found for
the first time in Porto Rico in March, 1930, infesting about 2 acres of
cassava, high above Comerio. Above 10 per cent of the underground stems
were rendered worthless for use.

BALATA

The banana root borer (Cosmopolites sordidus Germ.) is 'now generally
distributed in most parts of the island and doing, considerable injury to
bananas and especially to plantains in many sections.

COFFEE

The coffee Jooaf miner (Leucoptcra coffeella Staint.) was more injurious
than usual and morph injurious in the wetter sections than in those with






-35-


less rainfall. In the extensive seed beds 7rown by the 2gricultural
agents with the help of Red Cross funds for the rc.bilitation of the
coffee indistry the pest, ovin' to sy-stem?tic arid thorough' spra.ing,
was of little importance.

BEATS

The beetle (-'Yabrcti-.a graminea Baly has been more abundant and
injurious than previously, oving no doubt to the increase of plantings
of stri.: beans since the te hurricareof Septe.ember, 1328. Severe infes'tations
were reported from Cn
A bean leaf beetle, Cerotom denticornis Fab., wa's -eneraly present
in all bean plantings and doing some d1amae, especially where no spraying
had been done.

The bean lacebug <(Corythuch.ia rosoypii Fab.) was injurious to
several snall plantings of lina be-nv ,adurn. the s-mjjvzer of 1930 at Rio
Picdrs and at Palo Seco; the ]e.'ves turned '.hitish or brownish and. some
fell, greatly reducinG pod formation.

A leafhopper, L-poasa? sp., v.ar, common a:id often very injurious to
small patches of beans which were unsprayed.

The bean pod borer (PIaruca testulalis Gcy:r) was not very common
in lim-,a or strin- beans during tlje spring and s'iner, probably owing tob."
t-.2fact that the host plant is scarce during these seasons.

The bean leaf roller.. (G-oniurs roteus L. ) wvas present in most
plantings of beans that wore o-xazinad.

EGC-PLU-T

The potato flea beetle (-I' tri- cucuricris Iar. ) -,as v-er injurious,
es? rlly in seed-beds and in the ficld at -io Pio`ras from March to
Ma:,, 1930, but most of the da'-a in th-e field as usual ".'as done from
late September on.

The m'lon aphid (Ahis gossypii G-lov.) was more or less injurious
to eggplant all over the Island t':routh:out the :-car.

The eggplant lacebm (C,'" -ucl- mor.nch. Stal) '-s been common and
often very injurious 1:
Climbing cutitwcms (ioctuid-.e) did co2-sirlerablc d '.iA3,e to the buds
and to young eggplant on o-prrimental plots at the I.'sul'.r r::poriment
Station at Rio Pi':'r-.s.

A loaf tier (Psoara pcraqsialis Wal'.) has done cor.sidcrable daa..
to e-.,olant both in tho seed bed and in the field at Rio PieC'ras "rom
September to 'JJumr ,t little trouble has be.L notice- since.






-35-


ONION

The onion thrips (Thrips tabaci Lind.) was generally present during
the drier periods and was often very injurious to onions from January
to July.

Cutwori.ms (Noctuidae) were injurious to onions at Rio Piedras and
Cayey in onion seed bed during January and in the field from November
to March.

POTATOES, IRISH AND ',.JT

Around 300 acres of Irish potatoes were grown in the Island during
the year. An inspection tour to demoIostration plots at Comerio and
Barranquitas late in Februarry -.' e the crop was fairly well along showed
a fair amount of flea-beetle (pitrix cucumeris Harr.) damage, a few
leaflhoppers.. (q2poasca fabae Harr.), and a fewv aphids (Aphiidae).

The sweet-potato weevil (Cylas fcrmicarius Fab.) was present and
frequently very injuirious in apparently all parts of the Island.

A leaf miner (.rorjyza sp.) has been found in several localities
and while fairly common in some patches of sweet potatoes is of only
minor importance.

AIUAI^A

A moth (Dichomeris piperata Wlsi:. ) was first found in Porto Rico
last year (1929) reducin- the crop of alfa.lfa up to at least 30 per cent
on a 2-acre experimental plot under irrigation at the sub-experimental
plot at Isabela. The leaves are webbed together by the caterpillar and
skeletonizel. It was not present, however, on a small planting at Rio
Piodras.

A loaf-miner, Agroyza sp., was common in the field at Rio Piedras
during the early s-uraer but apparently not abundant enough to be
injurious to alfalfa.

CO;;P A

The cowpea pod and stal--! borer (1u.ndella cistipennis Dyar) was
reared from pods at Rio Piedras in :!'-y.

The tobacco budora (Heliothis virescens Fab. ) larvae were fairly
cor.rion, eating large holes in the pods .t Rio Piedras in !ay. Moths
emerge ed June 1 and 2, 1930, from papae formed from May 20 to May 23.

The liria bean pod borer (2Itiella. zinchenolla Trait.) was reared from
cowpea pods at Rio Piedras in nay.

COTTON

Several outbreaks of the cotton le.af norm (AlFo-' ar.illacea -,n. )
occurred throughout the cotton sectio:;, necessitating considerable spr:,in;.

The pinic' boll wiorm (Pectinophora goss'piella Sau:.d.) was tenerals.
distributed throughout the cotton s sections of the north anrd south coasts
but wag- not very injurious to cotton.

A leaf miner (ITepticula ossiprii ?Fbs. & Leon.) ,,-s first discovered
in March, 1930, and described as a new species. It 7ras present in the
majority of fields of cotton on the ;outh cost in 'the spring3 until crops
e.'re harvested, often with. nearly all the leaves full of miners, but
apparently little damage was done to the crop. To infestation was found
on north coast.

Cotton stainers (Dysdercus andreae L. ?,nd D. ue2&lectus Uhl.) ,ere
ge:.crally distributed but not ver: injurious, although abundant in several
cotton fields on the south coast in Marc.h, 1930.
The cotton lacebug (Corythucha gossy-pii Fab.) was present in s.a l
numbers on occasional leaves of cotton in various sections.

The cotton aphid (Aphi s I oss-pii Glov.) 'as- often found in small
numbers on the leaves of cotton.

A scale insect, Saissetia nira ITietn., vas ;err present and
often fairly abundant on cotton but apparently wTas of little importance.

A leafhopper, -.tpo'a.ca sp., was often found in small numbers
throughout the cotton-growing sections but was not injurious.

A leaf mite (Eriophyes !oss-pii Glov.) wras -c'-,crall;- distributed,
but scarce and doing but little injury.
