MOmN CRI cIT Infeostation as shown la g~ survey in the fall of 1935


Populations in all areas were greatly reduced from those of the 1934 survey, except in western lova eastern Nebraska, eastern Kansas, southern Wisconsin, and the northern hlialf of the Lower Peninsula of Michigan. In these areas light or local infestations have developed into severe or very severe ones. Heavy rains and cloudy weather during the hatching period greatly reduced the infestations of Camnula pellucida Scudd. and other species in northern Minnesota, northern Wisconsin, and the Upper Peninsula of Michigan. Melanonlus mexicanus Sauss. was the dominant species over most of the area. C. pellucida was greatly reduced in numbers by unfavorable weather. M. differentialis Thos. is building up again along the river courses of South Dalota, western Iowa, Nebravka, and Kansas. M. bivittatus Say is also increasing in these places, where succulent food was plentiful last summer, and is again becoming abundant in counties fringing the mountains in Colorado, Wyoming, and Montana. M. differentialis and M. bivittatus Say had become scarce under the severe drought of the past several years. U. femur-rubrum DeG. was numerous in alfalfa fields and grasslands in the more humid regions. M. packardii S-ud.d, was an important species in the Drkotas and Mountain States. Certain so-called prairie forms, as Aulocara elliotti Thomas, Ageneotettix deorum Scudd., and lDrpaopterna femoratum Scudd., were also abundant, causing much damage to grazing lands and cultivated crops adjoining in the stock-raising areas. (R. L. Shotwell, Bureau of Entomology and Plant Quarantine, U. S. D. A.)


An unprecedented outbreak of the mormon cricket is in progress in
some of the Western States. During the year eight States--lontana, Idaho, Wyoming, Nevada, Utah Colorado, Washington, and Oregon--reported outbreaks of varying intensity and extent, and all of these Stateu except Utah and Oregon carried on control campaigns. From extensive egg surveys made this fal], severe infestation may be anticipated next year. The accompanying map
showing the general location of infestations was prepared from the egg-survey data. The following acreage was found to be infested: Colorado, 3O0,300; Idaho, 1,815,104; Montana, 1,249,570; Nevada, 984,999; OrOegon, 23,000; Utah, 109,840; Washington, 199,750; Wyoming, 1,141,159; total, 5,831,752. The most threatening infestations are in Montana, Idaho, Nevada, and Wyoming, situated in or near the agricultural sections. The area of infestation in Washinlgton is relatively mall but is located in valuable agricultural land.

The coulee cricket developed into outbreak numbers in an area of 4,100 acres lying east of Cashnere and bordering the Wenatchee Valley in Chelan County, Wash. Considerable agricultural land is threatened. (F. T. Coan, Bureau of Entomolopy and Plant Quarantine, U. S. D. A.)


The great numbers of chinch bugs in hibernation at the beginning of
the year presaged the most severe and widespread outbreak in 50 years. They were mown to be abundant fran central Ok!lahoma to eastern Ohio, with the greatest density of population in issouri, southern Iowa, and central and northern Illinois. In the most heavily infested region thousands of bugs were often present in a sinJle clump of bunch arass, the maximum reported being about 60,000. The only area where winter mortality of

Twig and fruit injury by the oriental fruit moth was reported as light over most of the infested territory. A report from Illinois on July 24 stated that large numbers of larvae were entering peaches. In Ohio, although early peaches escaped injury and later varieties suffered little injury, quinces were severely damaged. Thie insect was discovered in the northwestern corner of Missouri in 1935, the first record for that part of the State. It had been present across the State line in Kansas since 1932. Our first report of its presence in Ne 1ampshire wVas received in September.


A very severe outbreak: of the eastern tent caterpillar occurred this year. The infestation was centered in the Ne' Bnglend States, southeastern Ne:' York, and New Jersey, and extended into northwestern 7ewT York, Pennsylvania, northeastern Ohio, through Test Virginia, eastern Kentucy, and into Tennessee ani! Georgia. As early as March 20 tents were being observed in Tennessee, and on March 25 the heaviest infestation on record was reported from the Fort Valley district in Georgia. The great abundance of overwintered egg masses started to hatch the last week of Mach in the latitude of Washington, D. C., and by the last week of April, they had been progressively reported as hatching all the way northw:ard to Vermont and Hew Hamps hire,. Within the next 2 months co'nlete defoliation s re-orted from much of the infested area and the insect had tr1:en a -lace as one of the outstanding tree insects of the season.


Glass fl-7 traps, baited :ith a solution of brown sugar and water,
have proved their value in locating infestations of Anastrenha ludens Loew in the Rio GranCe Valley. Through .hie use of these traps, adults were
in lhe use ofnd -ley -os ....s -!r
t ken on 166 premises and brush locations in 1934-35. The total number of flies trapped in the valley area as a7oproxiately 20 percent greater than the number trapped in 193-'4, but the number of premises known to be infested with adults decreased 5.7 percent. Larval infestations were located in grapefruit on 27 properties in the lower irt of the valley. As in the case of an a-ult infestation, the trees on all properties where larvae "',ere found were promptly sprayed and the fruit was buried, processed, or limited as to use. On account of finding infestations near Falfurrias in March, 1935, the regulated area was enlarged to include Brookls County, Tex. Besides A. ludens, 8 other species of fruit flies have been ta:en in traps in the Rio Gre ne Valley, but there has been no recorI of their attacking any fruit of economic importance. The local host of only one of these flies is known.a. A. allens Coq has been found to feed only in the seeds of Bumelia anustifolia. The _%aya fruit fly (Toxotrymana curvicauda Gerst.) has been captured, but this species is of no economic importance under valley conditions. The other 6 species taimn in the traps have not been found infestin:a fruit and comparatively little is known of their habits. Included among these finds were A. sermentina Uied, A. fraterculus Auct., and A. striat Schin. (. S. oidae, ureau of ntomology aend Plant quarantine, U. S. D. A.)

Up to and Including 1932 Records for 19a3 Records for 1974 Records for 1075


from 25 to 50 percent of the crop was threatened. The most significant feature of the season was the discovery of this weevil in Manatee County, Fla., in May. Scouting revealed the presence of the insect in nearly every pepper field in the county, but none in the adjoining counties. An eradication campaign was inaugurated and all of the pepper plants and wild host plants in the infested area were destroyed. In the collections of the National Museum there are specimens labeled "Mansura, La., June 29, 1904."


Reports on the survival of the Mexican bean beetle in cages at Colnmbus, Ohio, at Newrk, Del., and in the Estancia Valley, N. Mex., showed that the winter mortality was higher than usual. T1h.e beetle overcame this early handicap, and by the middle of July it had built up heavy populations over most of its range east of the Miscissi pi River. By the end of the season it had caused the most serious injury in several years. It extended its
range of destructive abundance and several points of new infestation were discovered. The accompanying map shows the spreacl. since 1932.


The curly-ton disease caused by the beet leafhorper was not so serious as in 1934. Cool, wet weather in the spring retarded development of the leafhopper in the San Joaquin Valley and little damage was done. The insect became normally abundant in Idaho and Utah and injured beets, tomatoes, and beans. Weather favorable to the growth of sugar beets prevailed in July and some of the curly-top injury to the crop was overcome.


A recently introduced weevil, Calomycterus setarius Roelofs, attracted considerable attention during the summer in isolated heavy infestations in Cuimberland County, Pa., Baltimore County, M.., and Litchfield and Fairfield Counties, Conn. A oreat variety of host plants were attacked. The weevil was first discovered in this country in 192) in Westchester County, N. Y., and in 1932 it was found to be established in Litchfield County, Cornn.


Damage by the boll weevil was comparatively light during 1935. Throughout the States where the weevil occurs the infestations varied greatly, even in limited areas. These variations in abundance were due to such factors as locl1 differences in rainfall, proximity to hibernation quarters, and whether or not the cotton leaf worm defoliated the cotton in the fall of 1934. In some counties Ouring midsummer the infestations ranged from less than 5 percent punctured squares in some fields to more than 90 percent in others. Although in all sections the weevils were largely held in check by n',tural conditions, t.iis 7as especially true in the southern and northern thirds of the Cotton Belt. In the region .-.ithin 200 miles of the Gulf coast in the States east of Texas the population 'was never heavy, except in limited )reas. This favorable condition that prevailed in the Gulf co: st region was due ortly to a light spring population, becusoe few weevils entered hibernation

Re-norts of. similar damage were received from the El Paso Valley of Texas and the 'esilla Valley of New Mexico. C. S. Rude re-orted the insect was present throughout the cotton fields of the Laguna district of Mexico in April and early in M'ay, and in marrr cases the cotton .as almost completely defoliated. Although in most cases the cotton recovered, it was considerably later because of the attack. (U. C. Loftin, Bureau of Entomology and Plant Querantine, U. S. D. A.)

The cotton aphid (Aghis gossy,)ii Glov.) occurred as usual wherever
cotton was grown. Usually it is the most important aphid attacking cotton, but a survey made Curing 1935 indicated that-A, medicap;inis Koch was more serious as a cotton yest and more generally .istributed in the Atlantic Coast States. Its attacks ere usually confined to the terminal buts and it is seldom seen on the large leaves, except in cases of extremely heavy infestations. A. *ossvrii weas frequently reported as serious in all parts of the Cotton Belt following the use of arsenical poisons but many heavy infestations were observed in fields where no arsenicals had been used. These leaf a-phils caused about the same amount of damage in South Carolina in 1935 as. during the previous year. In MDiississi)p)i no serious aphid infestation was observed in 1935, except on cotton that had been dusted. Heavy infestations developed on many plots where only three ap-lications of calcium arsenate were made during the season. In Louisiana cotton aphids were present in unusually large nubers and caused, some injury during the past season, perticularly.on poisoned cotton. In the vicinity of College Station, Tex., aphids were first observed on cotton in April and by May 1S were fairly abundant in many fields. The infestations began to decrease during the first week of June and remained low until the early part of August, following heavy dusting. The infestations were heavy during the remainder of the season and possibly caused some injury to small bolls, as some failed to develop to normal size and opened prematurely. At Port Lavaca, Tex., the aphids were compratively scarce on cotton during May and June during the period when infestation usually is most serious. The damage caused by root aphids (Anuranhis maidi-radicis _orbes, Trifidanlhis ahaseoli Pass., and FhomaloziSsp.) was far greater in 1935 than in 1934. (R. 7. Harned, Bureau of Entomolojgy and Plant Qurantine, U. S. D. A.)


Emergence of the cotton flea hopper from overwintered eggs _was about
normal in southern Texas during the spring of o1935. Although the general infestation in cotton fields was a little later than usual, weather conditions were favorable for its raid multiplication during the latter prt of May and during June. The hopper took a large toll of the early crop of cotton throughout southern Texas and also throughout most of the black-land belt of central Texas. The damage caused by this insect to the early crop and by the
leaf worm and boll weevil to the late crop caused a consi.erable reduction in the final yield, in the coastal and black-land sections of Texas. Croton was aundant last fall and, as this is the principal plant in '"hich the cotton flea hopper overwinters in the egg stage, conditions are favorable for a large number of these insects to hibernate successfully in this stage.

:here has been little increase in 1935 in the area mown to be infested by Anomala orientalis Waterh, One beetle was founi at a new location in Niew Jersey at Springfield, in Union County. There have been a few reDorts of minor turf injury from feeding by larvae. In 1935 the Asiatic garden beetle (Autoserica castanea Arrow) continued to spread. On Long Island all of iNassau County has no, been covered an- the insect has penetrated into the western part of Suffolk County. Prior to 1935, the southern part of Nassau County had been only lightly infested, but this year the insect has increased in numbers, resulting in more feeding on orna~entals and in vegetable gardens along the south shore of Long Island. The infestation in northern New Jersey now covers all of Essex, Hudson, and Union Counties and embraces parts of Bergen, Passaic, Eiddlesex, and Monmouth Counties. The old infestation in Pennsylvania locatedl in the Philadelphia suburban area has also shown a gradual increase in area. In 1935 beetles were fully as destructive to ornamental plants as in previous years, but fewer cases of injury to vegetable plants than in 19 3 ard lq)93- ere re-mrted. The insect was definitely more of a nuisance in 1935 than in any previous yea' in its habit of flying
about and alilting on persons in brightly lighted places. (C. H. Hadley, Bureau of Entomology and Plant Quarantine, U. S. D. A.)


The oblong leaf weevil (Phyllobius oblongus L.) was very abundant and caused noticeable injury to elm and maple near Painesville, Ohio, where it was first discovered in 19374. This weevil was first recorded in this country in 1923 from near Rochester, N. Y., where it was attacking, elms. The Survey has received no further reports on this infestation, although a report of injury to pear foliage was received from Penfield, N. Y., a fer miles from Rochester. The insect is widely distributed in Europe, .here it is a pest of various trees an2 is especially injurious to fruit trees.


Three soecirnens of a Japnnese weevil, 14yllocenjus gastaneus Roelofs,
Stahen on wild gra-pe, oak, and ash (?) a, short d istance from MIlontclair, il. J. on June 30, 1935. This weevil was -first taken in the Uni ted States in this locality in August 1937. Although this s-,ocics is not recorded as a rest in Asia, the genus contains many species that a-e crop ests, and one sr ecies is a very,, serious pest of cotton in India.

The area of contir~uous infestation of the Jananese beetle is now
esti-iapted at 11, 400 square miles, whicha is an increase of a",out 1,700 squ,;are miles. During the year the area was advanced northward into the highlrnd.1s of New Jersey, a notable advance in view of the retard-ation noted in that section in tGhe past 2 years.

Information regarding the distribution of 'Scolytus raultistriatus
Marsh., a ::-nown,. vector of the Dutch elm disease fung-us, was given in the Insect 1 est Surveyr Bulletin, Summa.4,ry for 1934, (vol. 1", no. 10, ?!- 3415). At that time its occurrence was recorded in localities in tw7.o etistinct area, one area being'i in eastern 4;assachusetts aiif, the other including
-ocrts of southwestern Connecticut, southeastern 11,7 York-, the northern half o f Nceu Jersey, and southeastern Pennisylvania.

these outlying towns; however, it is nown t.Irt the infestation in eastern :ssachusctts extends north over the New, Hampshire line, as the beetle has been reported from Nashua and North Hempton. It is also knowvin that the othcr infested area extends south into the extreme northern end of Delaware, where it.has been ta .en at Claymont. Outlyim reported infestations, vhich may or nmay not be isolated ones, having been reported from Egremont and Westfield, Mass.; Crescent, IN. Y.; and Torrington and Glastonbury, Conn. It is of interest to note that while this insect is abundant in the major Dutch elm disease zone centered around New York City, it has not been found in outlying infected areas in Indianapolis, Ind, Cleveland and Cincinnati, Ohio, Baltimore and Brunswick, 1d., Norfol-,.Va., or,Old Lyme, Comnn. The larger European elm bark beetle (S. scol'tus Fab.), considered the most important carrier of the disease in Evuroe, has not been found in the United States. (T. H. Jones, Bureau of Entomology a d Plant Quarantine, U. S. D. A.)


The hatch of eg clusters of the gypsy moth in the spring was quite variable, the low temperatures during the winter of 1934-35 being responsible for the killing of many clusters. However, the killing temperatures were not uniform in many sections of the infested areas, as considerable hatching of exposed egg clusters was noted in some localities. Egg clusters below the snow line showed a high percentage of hatch. Larvae were not abunclant enough to cause complete defoliation until they had reached maturity. During the summer a total of 540 ,769 acres of woodland was partially or totally defoliated, an increase of almost 50,000 acres over 1934. In Maine and New Hampshire the areas of defoliation were increased quite extensively. In Massachusetts there -as a slight decrease in the eastern and southeastern sections; ho-ever, in the western part of Worcester County and in sections of Franklin andc Hampshire Counties east of the Connecticut River heavy defoliation occurred, the areas affected being much more extensive than in 1934, and much greater than ever before recorded in this section of the State. Some of the areas entirely defoliated in 1934 suffered the same degree of injury in 1935. In Rhode Island there was a slight decrease in defoliation, while in Vermont there was a slight increase, and in Connecticut a considerable increase was noted. (A. F. Burgess, Bureau of Entoniology and Plant Quarantine, U. S. D. A.)


During the fall and winter of 1934-35 brown-tail webs were cut over most of the infested area in New Hampshire and M ssachusetts and some were cut in southern Maine by the State forces. In Maine slightly over 72,000 webs were cut and destroyed; in New Hampshire over 1,500,000 were destroyed; and in Massachusetts over 16g,000. During the summer of 1935 there were no reports of extensive defoliation, although in one or two towns in northeastern Massachusetts sli it defoliation was noted in limited areas. Throughout the insects range the infestation is rather light, being somewhat heavier in scattered towns. There are some areas in southern M1aine, southern New Hampshire, and southeastern Massachusetts where the winter webs are quite noticeable on fruit trees. (A. F. Burgess, Bureau of Entomology and Plant
Quarantine, U. S. D. A.)



In some sections of the infested area in 1New England, particularly in M.assachusetts, records obtained during the summer of 1935 indicate tnat the satin moth is on the increase. Although no extensive areas of defoliation were noted, the insect was abundant enough to cause noticeable defoliation in 29 towns :idely scattered over the entire infested area in assachusetts. For the most part, this defoliation was confined to a few trees. In Rhode Island noticeable defoliation was found on a few trees in one town, In ITew Hampshire some defoliation was noted in three towns scattered :idely over the infested area, but it was confined to a few trees in each place. There were no records of this insects being abundant enough in any town in Maine to cause noticeable dCefoliation. (A. F. Burgess, bureau of Entomology and Plant
Quarantine, U. S. D. A.) Note.--A survey conductedc in Oregon in July revealed the presence of the insect in Benton, Clacl2ams, Linn, Marion, Multnomah, Polk, Washington, and Yomhill Counties. No damage was being done, however, except near Gervais, Marion County, the site of the original infestation in Oregon. R. T. Webber, of the Bureau of Entonology and Plant Quarantine, reported that in Washington infestations in residential sections outnmber those in woodlands. The nrincinal woodland infestations lie between -Everett, Snohomish County, and Bellingham, Whatcom County, where willows seem to be the favored food plant. Other woodland infestations of an acre or more have developed to complete defoliations in Pierce and Cowlitz Counties. iMr.
Webber says: "'ive species of parasites of European origin, namely, Apanteles solitarius (Ratz.), Meteorus versicolor Wesm., Sunteromalus nidulans (Thom.),
gas unicolor Wesm., and Compsilura concinnata 1eiZ. were liberated (in western Washington) and all but R. unicolor were recovered. Only one species, A. solitarius, has established itself so Tell that its effectiveness is now apparent over the entire territory. Parasitization by this species in the localities of host abundance will reach 11.8 percent, increasing in its effectiveness in localities of host scarcity where it attained a maximum of 32.g percent."


CaLnkerworms occurred in outbren'numbers over much of the cortheastern States, with a severe infestation centering in southeastern iew York and iTew Jersey and extending into Maine. Scattered infestations occurred in northwestern Ohio, Illinois, western North Carolina, southeastern isconsin, southern lowa, Missouri, much of Kansas, and the Sacramento Valley of California. Severe defoliation of forest, shade, and fruit trees was reported. The fall species, Alsophila pometaria Harr., was most frequently named as causing the injury, although the sring species was commonly represented. A report of A. nometaria from Salt Lal:e County, Utah, gave a new State record for the spocios.


A small isolated infestation of the forest tent caterpillar was reported from the cost counties of MissisA-*?i an) across the State line in Washington and Saint Tan:any Parishes, La., the last of April and the first of May. A more extensive inifestation 2eveloned later in the season in southeastern eow York, and in Connecticut, csscbhusetts, Vermont, New Hanmsiire,


and the southern half of ,Maine. Cnsiderable defoliation of various trees was reported. The insect was reported in cQnsiderable abundance on raspberry in the northern noint of the Southern Peninsula of Michigan. It was reported from northeastern Minnesota as defoliating thousands of acres of birch, poplar, and willow.


A severe outbreak of the bag7orm occurred over most of the country
east of the Mississippi River, especially frcm a line drawn from central Ohio, Indiana, and Illinois southward to include Kentuc'y, Tennessee, Alabama, and Mississippi. Isolated infestations were reported from southeastern Nebrasha and central Texas.


The folloin note dated October 1, on Acas-aerops nigra Horn, was
received from C. F. Doucette: "Serious injury to bulbs and underground stems of Lilium longiflorvn by larvae has been observed in the southwestern coastal area of Oregon. In one planting about 15 percent of the bulbs were attacked,
t i inesato
and in spots 100 percent were attacked. There is evidence that the infestation originated from native lily bulbs growing in brushy areas near the plantings. It is apparent that the weevil is a real menace to the production of this species of lily bulb in this district." This is the first record of damage by this weevil to be received by the Insect Post Survey. Long, in his Catalogue
of the Coleoptera of America .orth of iexico, records the weevil as occurring in California.


Infestations of animals by screw wvorms -ere observed in the southern
part of Georgia and in northern and central Plorida during January and February 1935. The heavy infestation in southeastern Louisiana, southern ississippi, and southwestern Alabama was comuletuely wiiped out during the winter of 193)-35. In April and early in Mlay a few scattered cases began to appear in central and western Georgia and in southeastern Alabama. From the South, where the pest successfully overvintered, it spread northward as far as the southern boundary of North Carolina, into southeastern Tennessee, and westward through the southern half of Alabama to the eastern Mississippi line,
with only a few cases in the northern Alaba:na counties. For some reason, probably owing to the intensive campaign against the rest conducted by the Bureau and to certain ecological factors not yet determined, screw worm flies did not become reestablished in Mississippi and southeastern Louisiana in 1P35. As the season advanced, the incide-nce of infestation increased until the pea2: was reached late in the sumuoer or fall. Of the Southeastern States, Florida probably suffered the greatest damage from the pest, because of the longer season of fly activity and more favorable climatic conditions, which permitted the building up of a larger fly population. App7oximately 90 percent of the infestations occurred in cattle and hogs with the number of infestations in each of these two classes of animals about coual. As a result of the educational and control campaign, the screw- worm incidence in 1935 in the Southeast was not as high as in 1 3:. The highest percentages of infestation recorded for any weekly period during the 1935 season for the

various States are as follows: Georgia, 1.4; Florida, 4.2; Alabama, 0.5; Louisiana, 1.0; South Carolina, 9,.; and southeastern Texas, 1.6. The death loss 'ins even more markedly reduced. In the Southwest in 1935 observations indicated that the primary screw worm fly was able to overwinter, at least as far noth as Uvalde, Tex., as infestations occurred in January and Yebruary in that locality. The first cases in the vicinity of 1.enard, Tex.,were observed during the first half of April. Owing to the mild winter and suabsequent unusually favorable climatic conditions for fly propagation, the pest increased in enormous numbers, causing the mr.ost serious losi among livestock experienced in recent years. Fairly authentic data obtained from
ranchmen in this State show that in certain classes of livestock from 16 to 25 percent of the animals were infested, ith a mortality rate of about
6 percent ailing the infested stocl:. In New 1iexico, Ari zona, California, Oklahoma, Xansas, and Arkansas the screw worm was unusually abundant ar the losses were comparatively heavy. Outbreaks occurred in many localities in Illinois, Iowa, Nlebraska, Missouri, Indiana, and Xentucr. In these States many thousands of animals were infested and a good many were killed. These outbreaks were apparently started by shipments of infestcd animals into these States, mainly from the Southwest. After being introduced into these new areas, the fly was able to maintain itself and, by natural dissemination and the intrastate shipment of animals, the infestation spread rapidly from the points of introduction. (F. G. Bishop, Bureau of Entomology and Plant Quarantine, U. S. D. A.)


During 1935 the house cricket was reported as being extremely numerous in city Oumps ana houses at Lyons, Utica, and Auburn, U. Y., Little Falls, T. J., Niles, Mich., in the northeastern section of Washington, D. C., end at Clarendon and Lyon Park, Va. In all these localities the crickets bred to large numbers in the dum ns and later, during the AugustOctober period, flew or crawled in swarms into nearby houses, maki. g a nuisance of themselves by crawling everywhere, by their chirping, and by destructive attacks on shoes, clothing, ruags, Lrapes, umbrella covers, and other fabrics. (E. A. Back, Bureau of Entomology and Plant Quarantine, U. S. D. A.)


A scale insect, Lepidosaphes halli Green, was discovered on Prunus spp. and Agm ygdalus spp. in the grounds of the United States Plant Introduction Gardens at Chico, Butte County, Calif., on February 5 1934. An eradication campaign was immediately inaugurated and a report in June 1935 indicated that the insect had been completely wiped out. Foreign literature on the species is limited to the paper published in 1923 by E.E. Green, recording the original descrip-tion from specimens collected near Giza, Egypt.

Specimens of the following foreign insects have been identified from collections made in the United States.

Among specimens of Lepidoptera received for identification was one small moth, Laspeyresia coniferana PRatz. According to the associated data, this specimen was reared from larvae found in Pinus resinosa collected at Cross River, N.-Y., on June 27, 1934. The species-appoarently has not previously been reported from the United States. (Det. C. Heinrich)

Six specimens of a weevil collected on June 1, 1935, at Bellingham,
Wash., have been identified as Ceutorhynchus assimilis Pay:., a European species not previously reported from North America. Another specimen of the species is at hand from Vancouver, British Columbia, having been taken on May 28, 1931. (L. L. Buchanan)

Among lecfhop ers received for identification were included specimens collected on mignonette at Bar Harbor, Maine, on August 25, 1934. These
specimens have been placed as the European species Eupteryx auratus L. This seems to be the first record of the occurrence of this insect in North Aerica. (P. W. Oman)

On June 27 at Nicolaus, Clif., and July 5 at Puyallup, Wash., P. W. Oman collected specimens of a leafhopper on cottonwood which he has. identified as Idiocerus albicams Kbm., apparently the first records for this species from North America. There has also been received for identification a single female of an Idiocerus, collecteeC at Pullman, Wash., on October 13, -1929, which Mr. Oman tentatively placed as I, fulgidus Fab. Both are Eur)pean forms
living on Populus. '.r. Oman suggests that, if the latter identification is correct, all the above-mentioned specimens probab ly represent but a single species, as material in the National Collection under the name albicans Coes not appear to be specifically distinct from that considered to be fuL:idus.

Mr. Oman has had occasion to refer to and identify certain leafhoppers
he collected in New England in August 193L4. Of these, two are well-lnown European species but apparently represent new records for North America. These are Ath-s nus argentatus Fab. and Macronsis tiliae Burm. The first is apparently a grass feeder, as are closely related species of the genus, while the second, as the name suggests, lives on 111@ sp. The latter species is commonly referred to by Ei;ropean workers as Fedic1zes tie Burm. M. tiliae was collected at New Haven, Conn., and A. argent ts in the White Mountains of New Hamphire. (P. W. Oman)

On several occasions in the past 2 years, F. D. DeGant, of Cleveland, Ohio, has sent in specimens of an ichneumonid which he had reared, along with its wasp host, from rose stems in his garden. The parasite has been identified by R. A. Cushman as Perithous divinator (Rossi), a European species not heretofore recorded from North America. Grace Sandhouse has identified the wasp, with some question, as Pemphredon lethifer (Shuckard), a species recorded in European literature as one of the hosts of P. divinator. It has not previously been recorded from North America, although the collection of the National Museum contains specimens franm Rosedale, Mass.; Philadelphia$ Pittsburgh, and North East, Pa.; Baltimore, Md.; Washington, D. 0,; Oleveland, and Wooster, Ohio; Detroit, Mich.; Chicago, Ill.; and Webster Grove, Mo. All but the Philadelphia specimen, which vms captured in 1909, have been collected since 1922. Many of them were reared from rose or blackberry stems.

Specimens reared from elm logs at Morristown, N. J., a-nd in Westchester County, N. Y., were identified as Entedon leucogranma (Ratz.), a European species parasitic upon eacoptogaster spp., and not previously recordeC from America. (Det. A. 3. Gahan)

The first record of the occurrence of the sawfly Pristihora geniclata Htg. in the United States has been established by the identification of material in the collection of the National Museum by H. H. Ross, of the Illinois State Laboratory of Natural History. The specimens are from North Ada Mass., Delhi and Haines Falls, N. Y., and Mount Desert Island, Maine, and with one exception were reared from mountain ash, the first collection date being in 1926.

A scale insect, Leoidosaphes chinensis Chamb., was taken on orchid
(Cymbidium sp.) in a glass house at Lincoln Park, Los Azgeles County, alif., in July 1934. (Dato H. Morrison)

The 'first record in the United States of the sugarcane mite (Tarson emus bancrofti Michael) comes from a quarantine greenhouse at Arlinton arm Va. Since the discovery of the infestation, all the sugarcane in the vicinity of the infested house has been destroyed and the .house has been fumiated. Note.--In October the mite was discovered on sorguTam growing on experimental plats at Houma, La. Immediate steps were talen to eradicate the pest, which is seriously injurious to sugarcane in many tropical countries and islands.

Er. Ewing reports the third record for the United States of utetranychus latus (Can. & Fanz.) in the identification of specimens collected on boxwood at Arlington Farm, Va., on March 6, 1934.
