L, Sechrist left Washington on July 15 for an extended trip throughout the Intermountain States, where he will check up the work dene by the various cooperators who are assisting in the study of the cost of honey production. The results of this work have been very grati- fying. Later in the fall R. S. Kifer, of the Bureau of Agricultural Economics, which is cooperating in these studies, will make the final visit to all cooperators. At the completion of this year's work in the Intermcuntain States a similar study will be begun in the white-clover region, and the work in the two regions will be carried on simultaneously for a number of years. En route to Washington, Mr. Sechrist will judge the bee and honey exhibit of the Wisconsin State Fair, at Milwaukee, On June 11 Dr. E. F. Phillips, formerly Senior Apiculturist in charge of the Division of Bee Culture Investigations, was given the honorary degree of Doctor of Science by his Alma Mater, Allegheny College, Meadvilie, Pa.

He reports that it was one of the best meetings ever held by the Apis Club, with practically all of the prominent beekeeping investigators of Europe in attendance. Representatives from 21 countries were present. - 3 - W. J. Nolan judged the bee and honey exhibit at the Ohio State Fair, at Columbus, on August 26 and 27. The display was unusually fine, as the honey crop was the best in several years. Dr. W. W. Alpatov, of the University of Moscow, who has been studying in this country for the past two years as a Research Fellow of the International Education Board, has recently returned to Russia. On numerous occasions Doctor Alpatov consulted with the members of the staff of the Bee Culture Laboratory concerning his researches on the biometrics of the honeybee. He will continue his investigations in Russia. Jas. I. Hambleton appeared on the program of the Vermont State Beekeepers' Association at their annual meeting held at Barre, Vt., on August 30. The Association signified its willingness to compile a list of all beekeepers in the State of Vermont. This list will be available in checking the returns of enumerators in the 1930 census, when every effort will be made to compile reliable statistics on bees and honey. E, J. Hambleton, of Cornell University, visited the Bee Culture Laboratory on August 27, en route to the State of Minas Geraes, Brazil, where he will organize and conduct courses in entomology and apiculture at the Escola Superior de Agricultura e Veterinaria, at Vigosa. Through the intermediary of the Brazilian Ambassador and the Secretary of State of the United States, the Secretary of Agriculture was requested to suggest the name of a specialist capable of locating, organizing, and conducting an agricultural college on the "United States plan." Dr. P. H. Rolfs, formerly Director of the Agricultural Experiment Station and Dean of the Florida State College of Agriculture, was selected for this important mission. During the 11 years in which Doctor Rolfs has been administrative head of the college it has made great progress, and in the year about to begin special courses in entomology, apiculture, animal husbandry, and plant pathology are to be organized. Mrs. Richardson and Miss Theresa Dansdell, vrho are assisting Dr. H. E. Barnard, President of the American Honey Institute, in his work of organizing the White House Conference on Child Health, of which he is the executive secretary, visited the Bee Culture Laboratory on August 23 to study the system used by the Laboratory in cataloging beekeeping literature . - 4 - FOREST INSECTS F.

About 10 days were spent in Idaho and Montana, and a similar length of time in northeastern California. L. G. Baumhofer reports that a large number of Campoplex in- dividuals have been reared and introduced into more remote regions of the Halsey, Nebr., plantations, where the tip moth is abundant. Campo- plex is an eastern parasite of the tip moth; it has been successfully established in these plantations at Halsey, and is doing very effective work. R. A. St. George reports from Asheville, N. C., that the southern pine beetle has been particularly abundant this year. The dry season has apparently been favorable to it, and local outbreaks have occurred in many places from Virginia south through the Piedmont region. nr. T E. Snyder left Washington August 28 for Berkeley, Calif., to consult with Dr. S. F. Light, of the Termite Investigations Committee of the University of California, and Dr. A. E.

Guyton, of Harris- burg, Pa. , visited the Laboratory to confer with members of the parasite division concerning biological control. On August 26 seventeen members of the Philadelphia Horticultural Society visited the Laboratory. The work of the three major divisions of it was explained to them, E. R. Van Leeuwen telling them about beetle insecticides, J K. Holloway about parasites, and Max Osburn about soil insecticides . On August 26, also. Dr. Shiro Tashiro, Professor of Biochemistry, University of Cincinnati, Ohio, visited the Laboratory. On August 28, E. J. Hambleton, of the School of Agriculture, Vigosa, Minas Geraes, Brazil, spent the afternoon at the Laboratory. George Edward Spencer, Associate Entomologist engaged in physio- logical work at the Japanese-Beetle Laboratory, died August 29, shortly after an operation for cancer of the stomach. Mr. Spencer had been as- sociated with the work of this laboratory for the last seven years. He is survived by a wife and three young children. The Oriental Peach Moth Laboratory at Moorestown, N. J., is co- operating with the field laboratory at Vincennes, Ind., and the State entomological services of Indiana and Connecticut, in making experimental liberations of Macrocentrus ancyllvora in peach districts newly infested with the oriental peach moth. Over 3,000 adult parasites have been shipped to these points, and have arrived at their destination in good condition, with low mortality in transit. - 7 - From parasite-infested material collected from the Oriental Peach Moth Laboratory at Moorestown in June, Prof. J. J. Davis, of Purdue University, reports that 500 Macrocentrus ancylivora were obtained for liberations in orchards in Indiana, and that 22 per cent parasitism of this species has already been obtained in collections made for recovery of the parasite. Dr. Philip Carman, of the Connecticut Agricultural Experiment Station, spent several days late in July collecting strawberry leaf- roller larvae at the Moorestown Laboratory. He obtained 7,000 heavily parasitized larvae, and hopes to get a heavy emergence of Macrocentrus ancylivora for liberation in orchards in Connecticut. Dr. H. W. Allen and A. C. Hcdson, who have been investigating the influence of parasitism on infestation by the oriental peach moth in New Jersey, have found the parasitism of twig-infesting larvae to have been very high, in some collections reaching 100 per cent. The infesta- tion of fruit up to August 25 had not exceeded 11 per cent, including both visible and invisible injury, for any variety. TAXONOMY Harold Morrison, in Charge J. D. Sherman, Jr., of Mt. Vernon, N. Y., and his daughter visited the Division of Insects, August 6 and 7, on business relating to the pur- chase of various books from the estate of H. G. Dyar. H. K.
