On September 13, Dr. Walther Horn, director of the Deutsches Entomologisches Institut, left the Museum after spending about three weeks working in the Museum collection of Coleoptera. While here Dr. Horn named much of the undetermined material of the family Cicindel- idae . E. P. VanDuzee, curator of insects, California Academy of Sci- ences, spent September 12 to 15 working in the Museum collection of Hemiptera. Dr. Francis Rambousek, of Prague, Czechoslovakia, spent September 20 to 29 studying the Museum collection of Staphylinidae , with special reference to the Casey collection. He also discussed with the special- ists the methods employed in Europe for collecting minute subterra- nean insects, some of which have not been tried out in this country. Allan Nicolay, Brooklyn, N. Y. , called at the Museum September 22 to consult with some of the Bureau specialists and to examine spec- imens in the Casey collection. Mr. Nicolay is interested in the study of carabid beetles and weevils. Dr. C. E. Mickel, who was employed by the Bureau for 2j months to study critically the Museum collection of Mutillidae, returned to the University of Minnesota on September 22. G. P. Engelhardt, curator of the Brooklyn Museum, Brooklyn, N. Y., spent September 26 in the Division of Insects, studying the Museum col- lection of clear-winged moths. Frank Johnson, New York City, visited the section of Lepidoptera on September 28. - 5 - Dr. H. Morrison and Mr. H. S. Barber, of the Taxonomic unit, as- sisted Dr. R. G. Jeannel, of the Museum National d'Histoire Natural of Paris and Dr. C. Bolivar y Pieltain, of the Museo Nacional of Madrid, in their investigation of North American cave fauna during the period from August 24 to September 3. Dr. Morrison accompanied these two foreign visitors to caves in Indiana and Kentucky, and Mr. Barber to some of those in Virginia. The results of the trip were much enhanced in value by assistance from officials of the Indiana State Department of Conserva- tion, from Prof. H. Garinan, of the University of Kentucky, and from Prof. W. J. Schoene, of the Virginia Experiment Station. INSECTS AFFECTING MAN AND ANIMALS F. C. Bishopp, in Charge J. L. Webb has been tra.nsferred from the field force of the Divi- sion of Cotton Insects to the Washington force, Insects Affecting Man and Animals, and will assist in the administration of the Division. R. W. Wells returned to his field station, Beltsville, Md. , on September 12, after conducting a series of tests of methods of cat- tle grub control at Herkimer, N. Y. D. C. Parman, of the Uvalde, Tex. , sublaboratory, was in Wash- ington September 10 to 12 to consult with Bureau officials. D. G. Hall, Temporary Field Agent, resigned August 31 to ac- cept a scholarship at the Kansas State Agricultural College. Wesley G. Bruce was appointed Assistant Entomologist September 5, and was assigned to Cattle Grub Investigations, with headquarters at Fargo, N. D. During September he was engaged in a survey of the cattle-grub situation in the Red River Valley and at points in North Dakota, South Dakota, and Minnesota. Dr. Paul Vayssiere, Associate Director of the Entomological Station of Paris, visited the mosquito laboratory at Mound, La., on September 4. W. G. Bruce attended the eighth annual meeting of the Interna- tional Great Plains Crop Pest Committee, held at Fargo, N. D., Sep- tember 12 and 13. - 6 - FOREST-INSECT INVESTIGATIONS F. C. Craighead, in Charge Dr. F. C. Craighead spent the first week of September at Ashe- ville, N. C.,. reviewing the summer's work at the field laboratory at this point. He also spent a few days in the vicinity of the Mont Alto Forest School, Pa., with H. J. MacAloney, in studies of the white pine plantations in that region. The Mont Alto Forest School and the Pennsyl- vania State Forest Service gave them considerable assistance in this work. On September 27 H. J. MacAloney passed through Washington, D. C., on his return from Asheville, N. C., where he had spent 10 days in- vestigating injury by the white pine weevil in the Biltmore planta- tions. These plantations, 30 to 35 years old, are exceedingly thrifty and free from damage by the weevil. They are probably the finest planta- tions of this type in the East. Mr. MacAloney also spent some time in natural pine stands in this vicinity and in plantations in natural stands in central Pennsylvania. These studies are made in connection with the completion of three year's investigation of the white pine weevil. Floyd F. Smith, of the Pennsylvania State Department of Agri- culture, spent several days in Washington in the latter part of Sep- tember, conferring with Mr. Middleton and other officers of the Bu- reau on his entomological problems. R. A. St. George has returned to his official headquarters at East Falls Church, Va. During the summer just ended the greater part of his time has been devoted to participation in a study of the de- fects of timber that appear in the course of the normal operation of sawmills, conducted by the Forest Products Laboratory of the Forest Service, in cooperation with the Division of Forest Pathology of the Bureau of Plant Industry, in Virginia, West Virginia, and North Caro- lina. Much valuable information as to the character and extent of in- sect defects in hardwood lumber was obtained. Mr. St. George also spent several weeks at Asheville, N. C., in biological studies of the southern pine beetle. J. M. Miller, F. P. Keen, and H. L. Person spent a considerable part of the month of September on the Modoc National Forest, Calif., working in cooperation with Forest Service officials on a large tim- ber sale which has been initiated in that region. The motive of this sale, involving an entire township of Government land, was based en- tirely on the control of Dendroctonus b rev i com is Lee., which has de- stroyed nearly 20 per cent of timber in that region in the last 5 years. - 7 - J. C. Evenden spent the greater part of September in a survey of the Bighole Basin, in the State of Montana, checking up results of the $100,000 control project conducted by the Forest Service, and in mapping the new infestation by the bark beetle in this area preparatory to outlining plans for next year's work. The entire staff of the Coeur d'Alene, Idaho, field laboratory assisted in this undertaking. Through cooperation between this Division and the Forest Products Laboratory, four sets of timbers have been impregnated with 14 chem- ical wood preservatives; the sets will be sent to South Africa, Aus- tralia, Hawaii, and Panama, respectively, to be tested as to preserv- atives in preventing attack by termites. Competent entomologists at these locations will report on the results of the tests. The entire Division of Forest Insects moved its quarters in the latter part of September, occupying the rooms on the north side of the Insectary Building.

Atwood, Junior Entomologist, stationed at the Gipsy Moth Laboratory, resigned August 31. He will teach in the high school at Haverhill, Mass. R. L. Wallis, a graduate of the Colorado Agricultural College, has been appointed Junior Entomologist, to report for duty at the Gipsy Moth Laboratory on September 1. Dr. F. C. Craighead spent August 18 to 23 at the Gipsy Moth Labor- atory. C. W. Collins, T. H. Jones, M. T. Smulyan, and J. V. Schaffner, Jr., of the Gipsy Moth Laboratory, attended the Fourth International Congress of Entomology at Ithaca, N. Y., August 14 to 16. TROPICAL, SUBTROPICAL AND ORNAMENTAL PLANT INSECT INVESTIGATIONS A. C. Baker, in Charge In September the final plans were completed for the Northwestern Laboratory at Puyallup, Wash. The details of construction of the lab- oratory plant are being handled for the growers by the Commissioners of Pierce County, and the first bids were received on September 24. This laboratory will be devoted to the study of insects attacking ornamentals in the Northwestern States. The main building will be 32 by 40 feet and, besides office space, will contain laboratories for the chemical and biological phases of the work, dark room, cold room, etc. The plant will have a 75-foot greenhouse for experimental work under glass, which will be divided into three 35- foot houses, permitting varied conditions of culture and treatment. This laboratory is being handled by Mr. Doucette, who has had considerable experience with pests of ornamentals in Pennsyl- vania, California, and the Northwest. In September, also, the minor details of construction of the Mex- ican Laboratory were completed. This plant, supplied by the Mexican authorities through the cooperation of the Qfi.cina para Defense Agri- cola, is composed of two concrete buildings with suitable grounds. The one building contains a large office and a laboratory for the study of the qualities and composition of different host fruits in relation to infestation by the Mexican fruit worm. This building also contains a chemical storeroom, engine room, and bath. The second building contains six laboratory rooms, arranged on both sides of a central covered passage through which trucks can be driven to the doorways of the laboratories. In this building the various pieces of control equipment have been in- stalled. These will permit the control of climatic conditions such as temperature, humidity, and atmospheric pressure, so that climatic condi- tions in any fruit-growing region of the United States may be duplicated. Here the fruit worm will be grown and studied under conditions as nearly as possible like those of American regions to which it may gain access. - 9 - The work of the laboratory at Mexico City is being supplemented by field work and studies in an insectary located in Cuernavaca. Ideas obtained from field observations may therefore be checked under controlled conditions in the laboratory. On September 24 Dr. Hugh Darby and Miss Eleanor Kapp reported for duty at the Mexican Laboratory. Dr. Darby will have charge of some of the specialized phases of the work of the laboratory, and Miss Kapp will serve as laboratory assistant. Dr. Darby came into biology as a physicist trained at Cambridge, England. He did his undergraduate work in biology and received his doctorate at Columbia University, where he specialized in insect physiology. Miss Kapp has received both the 8. A. and M. A. degrees from Columbia University, and has since done special graduate work on laboratory methods in biology. Dr. Elisabeth Skwarra, a specialist on the relation of insects to their environment, reported for duty in Mexico September 18, She came to the United States as an official delegate to the Internation- al Congress at Ithaca, and accepted a six months' appointment in Mexico to gather data on the influence of environmental conditions on the pupae of the Mexican fruit worm. Her appointment covers the period of the ripening of the fruit and the pupation of the larvae. The data gathered by Dr. Skwarra will be studied in relation to the facts gathered in the laboratory and insectary. The insectary in Cuernavaca is handled by Mr. McPhail, formerly entomologist of the Citrus Experiment Station of Texas. Mr. McPhail made most of the discoveries of the Mexican fruit worm in the Rio Grande Valley, and his knowledge of citrus insects and conditions is of much value in his present work. At the Central California Citrus Institute, held at Lindsay, Calif., September 21 and 22, 1928, an address was made by E. A. Mc- Gregor on the subject "Citrus Thrips Control." This proved to be the best attended Institute in the history of central California, there being about 500 present. BEE CULTURE INVESTIGATIONS James I. Hambleton, in Charge The new Southern States Bee Culture Field Laboratory was opened on July 16 at Baton Rouge, La., with W. J. Nolan acting temporarily in charge. Dr. W. W. Whitcomb, jr., .who has received his doctor's degree at the University of Wisconsin and was recently engaged in entomolog- ical work for that State, accepted a position as Assistant Apicultur- ist with the Bureau of Entomology on July 18; and after spending a couple of weeks at the Bee Culture Laboratory at Somerset, Md., left - 10 - for Baton Rouge. He there took charge of the Field Laboratory on August 30, and Mr. Nolan returned to Washington. Mr. Nolan gave a talk con- cerning the new field laboratory at a meeting of the Louisiana State Beekeepers' Association, held on July 25 and 26, and also at the Southern States Beekeepers' Conference, in session at Texarkana, Tex., on August 6 and 7. Later, he participated in the beekeeping program of Farmers' Week, held by the University of Florida, at Gainesville, Fla., on August 13 to 18. Doctor Whitcomb also attended the Texarkana meeting. On their return from Texarkana, Mr. Nolan and Dr. Whitcomb, in company with Jes Dalton, made a survey of the package-bee business around the Hamburg center in Avoyelles Parish, La. Dr. L. M. Bertholf, who continued this summer at the Bee Culture Laboratory his studies on the reaction of bees to light of various wave- lengths and intensities, resigned his temporary appointment as Field Assistant on September 10, to resume his duties as Professor of Biology at Western Maryland College, Westminster, Md. Miss Mary Louise Crossman, temporarily employed as Field Assist- ant at the Bee Culture Laboratory, resigned on September 13 to assume teaching work at the East Falls Church High School, East Falls Church, V a. Ralph K. Day, who has been temporarily employed as Field Assist- ant at the Bee Culture Laboratory, and who worked on color change in honey, resigned September 18 to resume graduate work at the California Institute of Technology, Pasadena, Calif. Prof. C. L. Farrar, in charge of beekeeping at the Massachusetts Agricultural College, Amherst, visited the Bee Culture Laboratory on September 11. Dr. Everett Oertel, who has been assisting in the beekeeping work at Cornell University, and Mrs. Oertel visited the Bee Culture Labora- tory several days in the week of September 10. Prof. Shujiro Inomata, Entomologist at the Agricultural College, Tottori, Japan, visited the Laboratory on September 25. Professor Inomata states that courses in beekeeping will be given at the Agricultural College at Tottori. Jes Dalton, of St. Francisville, La., for the last few years pres- ident of the Louisiana State Beekeepers' Association, was appointed September 20 a collaborator of the Bee Culture Laboratory. Prof. F. B. Paddock, of the Iowa Agricultural College, Ames, Iowa, visited the Intermountain Bee Culture Field Laboratory, Laramie, Wyo., in the week of September 10. John C. Ferris, of the East Coast Canning Co., Jacksonville, Fla., called at the Laboratory on September 18 to discuss methods of bottling honey 11 Roth Hamilton, of the firm of Hamilton, Wallace and Bryant, Los Angeles, Calif., exporters of honey, conferred with Jas. I. Hambleton on September 24 in regard to foreign honey markets. Mr. Hamilton stopped in Washington after an extended trip through Europe, where he made a careful study of the honey markets. The Bee Culture Laboratory has just received two Pfund honey graders which are to be assigned to the offices of the United States Trade Commissioners in London and Hamburg, there to be available for use by foreign buyers of honey. Through private generosity these graders are being sent abroad without cost to the Government. LIBRARY Mabel Colcord, Librarian NEW BOOKS Bateson, William. William Bateson, F. R.
