Lyctus powder-post beetles. Mr. St. George is also to report on the present status 
of an epidemic of the southern pine beetle, Dendroctonus frontalis Zimm. 
According to Science , the attention of entomologists throughout the world is 
called to the fact that, beginning with the volume for 1922, the preparation of the 
“Insecta” part of the Zoological Record is being undertaken by the Imperial Bureau of 
Entomology. In order that the Record may be as complete as it is possible to make 
it, all authors of entomological papers, especially of systematic ones, are requested to 
send separata of their papers to the bureau. These are particularly desired in cases 
where the original journal is one that is not primarily devoted to entomology. All 
separata should be addressed to the assistant director, Imperial Bureau of Entomology 
41 Queen’s Gate, London, S. W. 7, England. 
Mr. W. N. Keenan of the Division of Foreign Pests Suppression spent ten days in 
Southern Ontario in connection with the European corn borer work, where he 
arranged for the inspection of cut flowers and vegetables for export to the United 
States and also for the maintenance of the quarantine. Warning posters are being 
placed at all road intersections leading out of the quarantined area, informing the 
general public that it is against the law to remove corn from the infested districts. 
An experimental demonstration was started by the Bureau of Entomology nearly 
two years ago with a local bsuiness firm, in which the Bureau undertook to eliminate 
loss for the two-year period to stocks of brushes by fumigation with hydrocyanic acid 
gas. The company provided a room in which to store their stocks and in which they 
could be fumigated without moving. The experiment has demonstrated the possi¬ 
bility of preventing losses of this kind by the methods adopted, and the company has 
been the gainer by several thousand dollars annually. 
The temporary parasite laboratory at St. Thomas, Ontario, with Mr. A. B. Baird 
in charge, is now well under way and owing to the extensive and well organized 
“clean-up” campaign, instituted by the Division of Field Crop and Garden Insects, it 
has been a difficult task to secure enough hibernating European corn borer larvae for 
the breeding of the parasites. By transferring men from other lines of work it was 
possible to collect 26,000 larvae up to June 1st. Mr. H. A. Dyce of the University 
of Toronto, has been appointed to assist Mr. Baird. 
Dr. H. L. Dozier resigned his position as Entomologist, U. S. Bureau of Entomology 
in charge of the Camphor Scale Investigation Laboratory at New Orleans, La., 
April 1st, to accept the position of Entomologist for the Gulf Coast Citrus Exchange 
in charge of their research and field service problems, dealing primarily with the 
Satsuma orange. A fully equipped office and laboratory has been established at 
Houston St., 1 S. of Government, Mobile, Ala., to carry out these investigations. 
Much progress has been made during the past fall and winter in cleaning up the 
purple and camphor scale on the Satsuma orange in Southern Alabama, using standard 
oil emulsions. 
The following amendments to the Regulations under the Canadian Destructive 
Insect and Pest Act were recently passed: Amendment No. 19, passed May 31, 
1923, prohibiting the importation of certain cut flowers and vegetables from the 
areas infested by the European corn borer in the United States (Amendment brings 
up to date the old regulation). Amendment No. 20, passed June 4, 1923, amends the 
previous regulation by adding European Buckthorn ( Rhamnus cathartica L.) to the 
list of plants prohibited entry, on account of its being a host of the disease causing
