NEW POSTAL REGULATIONS. 
The following statement of the revised regulations of the Post- 
office department concerning the transmission of insects through the 
mails has been kindly supplied by Dr. L. O. Howard, Chief of the 
Bureau of Entomology: 
“Queen bees and their attendant bees, when accompanied by a 
certificate from a State or Government inspector that they have been 
inspected and found free of disease; beneficial insects, when shipped 
by departments of entomology in agricultural colleges and persons 
holding official entomological positions; other live insects, when 
addressed to the Bureau of Entomology of the United States Depart- 
ment of Agriculture, to departments of entomology in State agricul- 
tural colleges, and to persons holding official entomological positions, 
and dried insects and dried reptiles may be sent in the mails when so 
put up as to render it practically impossible that the package shall be 
broken in transit, or the persons handling the same be injured, or the 
mail bags or their contents soiled. 
“Nursery stock, including field-grown florists’ stock, trees, shrubs, 
plants, vines, cuttings, grafts, scions and buds (which may carry injuri- 
ous insects) may be admitted to the mails only when accompanied by a 
certificate from a State or Government inspector to the effect that said 
nursery stock has been inspected and found free from injurious insects.”’
