Forty pathogens which are included in the list of common diseases for which at 
least some interceptions were recorded but which were recorded fewer than 10 times 
each during the year were intercepted a total of 187 times. Some additional 
species which have been included in past lists were not recorded at all during the 
year. 
Total recorded interceptions of these common diseases, 8,51 L 
INCOMPLETELY DETERMINED PESTS 
Owing to the nature of the material, many of the insects and plant diseases 
intercepted cannot be determined with accuracy. Some of this material has been 
partially determined and serves as the basis for the brief notes that follow. 
INSECTS 
Of the pests intercepted a total of 162 could be determined to family, subfamily, 
or tribe only. A total of 4,361 other lots of insect pests, determined to genus only, 
were distributed among 868 genera. The largest number of interceptions included 
under any one of these 868 genera is 172 under Pseudococcus, which arrived from
