and which should make each succeeding measure easier to participate in 
for all concerned. 
In conclusion I would present for further discussion a summary of the 
above mentioned factors that are concerned in the success of domestic 
quarantines. 
(1) The desirability of a basic law providing ample power to deal with 
emergencies, whether these involve considerations of time or place or 
magnitude. 
(2) For enforcement of this law there should be maintained ready for 
action a well-trained staff, not necessarily large, but so organized as to 
be readily extensible in any direction. 
(3) An adequate emergency fund should be maintained for sudden use. 
(4) Adequate survey work should be intimately and promptly corre¬ 
lated with every quarantine. 
(5) Provision should be made for emergency research so that through 
extensive and intensive effort there may be quickly obtained data 
sufficient to form the basis of a permanent policy. 
(6) The quarantine plan should include at the outset sufficient means, 
enough men and such careful methods that its success will be assured. 
(7) Quarantine regulations should be simple, clear, and not dis¬ 
criminatory. 
(8) The personnel of a quarantine staff is an important factor in its 
success; hence direction of this work should be entrusted only to men of 
outstanding ability. 
(9) The public eventually judges a quarantine by the fairness, im¬ 
partiality and thoroughness of enforcement rather than by the severity 
of the restrictions. 
(10) Popular support is a valuable aid to success and to obtain it 
much effort of an educative kind is worth while. 
An Exotic Coccid Taken in the United States. Nipponorthezia ardisiae Kuwana 
was taken in the nests of mound building ants by the writer near Rockville, Pa., on 
Feb. 14, 1921. Specimens were determined by Mr. Harold Morrison, U. S. Bureau 
of Entomology, Washington, D. C., who reports the scale as a native of Japan on the 
roots of Ardisia japonica. This represents a genus heretofore unknown on the 
North American continent.
