know as much about them as I should. So I move that a geographically 

 representative committee be appointed by the Chair with Mr. Sasscer 

 as chairman, to take this matter under consideration and see whether 

 any general rules, fundamental principles and recommendations can 

 be laid down, this committee to make its report at the next session of 

 this section. 



Mr. S. B. Fracker: I second the motion. A nimiber of our men 

 in Wisconsin keep a httle outside shrubbery in order that they may 

 be entitled to carry a nursery inspection certificate, and they attach 

 it to greenhouse plants when requested to do so by the express agent. 

 This is true particularly of inter-state shipments. The problem, we 

 have felt, was a serious one, not only owing to the dangers from some of 

 the insects mentioned by Mr. Dietz, but in other ways. For example, 

 the orchid weevil, Cholus cattleyae, has been distributed from one green- 

 house to another by means of stock, and its distribution could probably 

 have been prevented if inspection certificates had been required. It 

 is an insect which is perfectly ruinous in the orchid houses when it once 

 becomes established. 



The motion of Mr. Headlee, seconded by Mr. Fracker, was voted 

 upon and carried. 



Chairman Ruggles: The next paper on the program is "Important 

 Foreign Insect Pests Collected on Imported Nursery Stock in 1921." 

 by Mr. E. R. Sasscer. 



IMPORTANT INSECTS COLLECTED ON IMPORTED NURSERY 



STOCK IN 1921

 during the fiscal year 1921 from all foreign countries in compliance 

 with Regulations 3 and 14 of Quarantine 37. Of this number, 21,172,- 

 049 plants arrived from France, the remainder being distributed among 

 all other countries exporting to the United States. In spite of the 

 emphasis which has been repeatedly made regarding the necessity of 

 shipping only plants free from soil or earth, a nimiber of shipments of 

 plants, the roots of which were in part embedded in soil, arrived. 

 Moreover, in several instances the soil included in the matted roots of 

 Astilbe from Holland was found to be infested with the larvae of Bra- 

 chyrhinus sulcatus Fab. which would have escaped the notice of the 

 inspectors if the soil had not been detected, removed, and carefully
