Lepidoptera and Coleoptera are always copiously represented, while 

 such orders as Thysanura and Thysanoptera in most cases are 

 obviously neglected. However, one museum tabulation with percent- 

 age designations added, is herewith appended as a further demon- 

 stration (notwithstanding the defects just pointed out and the ap- 

 proximate nature of some of its figures) that multiplicity of species is 

 more or less closely correlated with abundance of individuals. This 

 table is adapted from one presented by Dr. J. M. Aldrich in the 

 Smithsonian Report for 1919 (1921), p. ^y^.
