Excerpt from Memoirs on the Coleoptera, Vol. 7: 1916 One source of confusion is that the word variation is generally misunderstood and the differences due to environment so attributed. These latter divergencies do not by any means indicate variation in the proper meaning of that word, but the beginnings of separate species, at first as slightly different taxonomic forms and finally as true species. Such forms unless very distinct, as in the case of many Omus and Brennas modifications, can be designated as sub species for convenience, when it is thought advisable to record them by name; it is not necessary to invent lesser categories in the present lack of full knowledge of the subject. The estimation of actual taxonomic weight of these related forms is of course a matter of individual judgment. In some of the cases above mentioned the specific status should be self-evident and other cases may be decided provisionally, with more or less precision, by any one accustomed to view the processes of nature, in any field, with moderate intelli gence and discrimination.
