giving illustrations of the character of the insects' work and describing causes and 

 remedies and calling special attention to the importance of community effort in con- 

 trol operations, were also on exhibition and for distribution. 



According to Science, Chicago University on its twenty-fifth anniversary conferred 

 the honorary degree of Doctor of Science on Professor William Morton Wheeler, 

 dean of the faculty of the Bussej' Institution of Harvard University. 



Mr. H. L. Sanford, Bureau of Entomology, recently collected what appears to be a 

 new and undescribed species of Aonida on condurango pods from Ecuador. On 

 April 1 he also intercepted Parlatoria chinensis on peach from Northern China. This 

 scale insect is a common and widespread species in Northern China and represents 

 a very undesirable importation. 



Mr. W. W. Yothers, Bureau of Entomology, in company with Messrs. W. J. Krome 

 and L. S. Tenny, members of the Florida Plant Board, left Orlando on June 19 for 

 a brief trip to Cuba to study the various insects infesting citrus on this Island. En 

 route Mr. Yothers will stop off at various points on the Florida Keys to further in- 

 vestigate insects infesting limes. 



Dr. Paul Marchal has prepared a book which will soon appear giving an account 

 of his visit to America. The title, translated, is "The Biological Sciences Applied to 

 Agriculture and the Struggle against the Enemies of Plants in the United States." 

 The volume will cover about 400 royal octavo pages, and is enthusiastic in its praise 

 of the organization of the Bureau of Entomology. 



Mr. C. H. Popenoe, Bureau of Entomology, will visit the stations which have 

 been established, in cooperation with the Bureau of Plant Industry, for investigation 

 of insects as carriers of mosaic, wilt, and other diseases of cucumbers and other cucur- 

 bits in the states of Wisconsin, Michigan, and Indiana. He will supervise the prepa- 

 ration of experimental plats with reference to the control of these insects and for 

 community demonstration experiments. 



Messrs. A. F. Burgess, D. M. Rogers, and L. H. Worthley were in Washington 

 during May to attend the hearing before the Horticultural Board on the quarantines 

 of the gipsy and brown-tail moths. It was decided by the Board that the present pro- 

 vision under which Christmas trees and greens are shipped from the infested territory 

 under inspection will be continued. It was also decided that notices of all shipments 

 which are inspected under the quarantines will be sent to the officials in the states to 

 which they are forwarded. 



The beet or spinach leaf-minor {Pegomya vicina Lint.) has been reported injurious 

 in various sections of New York, and especially on Long Island, to table beet and Swiss 

 chard, the latter being a new food plant. Agents and correspondents will assist in 

 investigations of this insect if they will kindly send leaves of sugar beet, table beet, 

 spinach, and chard, infested by this insect for possible rearing of parasites. Nicotine 

 sulphate and other reagents should be tested as repellents or deterrents to protect 

 against the adult or fly depositing her eggs on the leafage. 



According to Canadian Entomologist, Dr. Alfred E. Cameron has been appointed 

 a field officer of the Entomological Branch, Ottawa, Canada, and will be specially 

 charged with the investigation of the pear thrips and other insects in British Colum- 

 bia. Dr. Cameron graduated from the University of Aberdeen in 1909, received the 

 degree of Master of Science from the University of Manchester in 1912, and after 

 holding a Government Scholarship and conducting investigations in England and the
