This book was released on 2018-03-17 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Preliminary Classification of the Superfamily Scolytoidea It is evident that the scolytoid beetles could not have been derived from the highly differentiated carabids or scarabaeids and that these groups could not have been derived from any existing group of the Rhynchophora.. It is also evident that the Species in the two primary divisions of the Coleoptera which may be the nearest representatives Of their primitive ancestors are themselves so highly differentiated from one another and from ancestral forms of Coleoptera that they can not be recognized, or, if they could, they would be of little or no use as a basis for Speculation on the origin and evolution of the order; then, too, we have no material in fossils on which to base a reliable hypothesis, because only the highly specialized forms have been pre served. 'therefore we must rely on facts as they exist and endeavor to discover and interpret the elements of distinction and relationship which have survived in the course Of their evolution, under the influ ence of natural selection, dominant differentiation, and progressive and parallel evolution. The writer's interpretation of these facts, SO far'as they apply to morphological characters and the distinction of groups and Species, will be expressed in the tables of families, sub families, genera, and Species, in the succeeding contributions toward a monograph, as will also the progressive modification of characters indicative of the lines of divergence from one extreme toward the opposite.
