attended a very interesting Imperial Conference, called by the British Ministry of 
Agriculture and Fisheries, to consider Imperial Legislation in connection with the 
exchange of plants and plant products throughout the Empire. This conference was 
held on July 17. 
Entomological News records the death of the following entomologists: Philippe 
Grouvelle, August 2, 1923; Jules Grouvelle, November 6, 1923, both coleopterists of 
France; Edmond Bordage (date not given) also of France; Charles Oberthur, the 
great lepidopterist, June 1, R.ennes, France; Frederick Merrifield, May 28, 1924, 
Brighton, England, a lepidopterist; Dr. David M. Castle, a coleopterist and member 
of the Feldman Collecting Social, Philadelphia, August 6, 1924. 
Mr. H. L. Viereck, who was definitely appointed to the position of assistant en¬ 
tomologist in the Division of Systematic Entomology, Canadian Department of 
Agriculture, on August 1, has marshalled all of the Hymenoptera in the National 
Collection so that it is now possible to tell when one looks at a species, whether all the 
available material is at hand. Mr. Viereck has also made considerable progress in the 
listing of Canadian Hymenoptera and the work is nearing completion. 
Mr. M. J. Forsell of Everett, Washington, has recently been appointed junior plant 
quarantine inspector with the Federal Plorticultural Board, and stationed at Seattle, 
Wash. Previous to this he was horticultural inspector with the State of Washington 
Department of Agriculture where in addition to his usual duties, he made a special 
study of the strawberry root weevil, working out the life history and making special 
migration studies. This pest is the most puzzling problem of all among the berry 
growers of the Puget Sound region. 
Prof. W. M. Wheeler of Harvard University has sent to the U. S. National Museum 
paratypes of an extraordinary larval myrmecophile which he collected in Panama and 
recently described as Nothomicrodon aztecarum, new species. They are very small 
insects with no legs and few organs, shaped like a little bag or flask with the head 
sticking out at one end. It is supposed that they belong to the Diptera, but it is 
impossible to tell with any certainty to what family, as no one has previously found 
anything like them. 
Mr. C. N. Ainslie, entomologist, in charge of the Sioux City laboratory of the 
Bureau of Entomology, visited Beach, N. D., during August, to investigate a severe 
infestation of the Hessian fly in western North Dakota, where he found the insect more 
abundant and injurious than for many years. He gathered valuable notes relating to 
the insect and its parasites in an unusual environment. He also planned a trip to 
northeastern Montana to confer with Dr. J. R. Parker of the Montana Experiment 
Station concerning the new infestation of Hessian fly in that State. 
Captain Bartlett, who commanded the vessel “Roosevelt” on Peary’s expedition 
to the North Pole, called on Dr. Aldrich at the U. S. National Museum. October 1, 
to clear up some questions concerning specimens collected on the expedition. The 
specimens had been previously sent to the Museum in pill boxes, with only the date 
and locality of collection. It is believed that as a result of this conference with 
Captain Bartlett more information will be available, the specimens will be of more 
value, and a more accurate record will be preserved of the entomological results of the 
expedition. 
Prof. Geo. A. Dean returned to Washington September 16 from an extensive trip to 
several of the entomological laboratories of the Division of Cereal and Forage Crop
