Coleopterological Notices, Vol. 5 (Classic Reprint)

Excerpt from Coleopterological Notices, Vol. 5

In bringing together a number of short studies of our North American Coleoptera under the above title, the methods and objects held in view in the other parts of the present series are continued. The systematic revisions do not pretend to approach completeness, and are merely efforts to indicate the probable interrelationships of the species, based upon such material as it has been found possible to gather together. New forms are continually being brought to light, which sometimes tend to alter previously formed conceptions of specific limits, or to destroy or modify the value of characters assumed as the bases and criteria of classification. This is the natural outcome of all endeavors to evolve the laws of complicated affinities from inadequate data, but, at the same time, it is not always necessary or advisable to defer the announcement of such apparent truths as we have been able to discover with the material at our disposal; if carefully conducted, I believe that they may, and generally do, lead onward and upward.
