INCOMPLETELY DETERMINED PESTS 
• Many intercepted insects and plant diseases cannot be determined with accur- 
acy. Material may be scanty and in poor condition. The life histories of some 
insects are imperfectly known, or in the stage present two allied species may be 
almost indistinguishable, or the one or two specimens obtained may not be quite
