TABLE 5. Diversity indicies of bee collecting by major entomologists. Some entomologists collected a relatively smaller number of species per specimens than others, reflecting low relative species diversity. For example, Mr. Hans Joseph Bredo (n = 1,050) collected the greatest number of sepcimens, yet a smaller number of species than did Dr. Joseph Charles Bequaert (ranked fourth in terms of abundance), deliberately recording the highest species richness on his 288 specimens, so great species diversity.
