INCOMPLETELY DETERMINED PESTS 
Many insects and pathogens are in such a condition that no accurate determi- 
nation is possible Others are new to science or belong in species not represented 
in the collections of authoritative material and are not described in sufficient 
detail to make positive determinations possible.
