Title:Studies of the Life History, Habits, and Taxonomic Relations of a New Species of Oberea (Oberea ulmicola Chittenden)
Author(s):Webster, F.M.
new species
Abstract:The species of this genus of Ceramhycidm are not easy to define, on account of their variability in color, and they have for this reason been the subject of repeated and radical revision by entomologists. In 1878, Dr. G. H. Horn, in his revision of the genus* restricted the number of species to eleven, while Mr. Chas. W. Leng, eighteen years later, reduced this number to five. In this latter revision Oheyea tripiindata Swederus v^^as divided into two groups, or forms as they are there called, the bi)nacN/ata form and the tripunctata form, the species itself being thus burdened with no less than eleven synonyms. Even this arrangement is unsatisfactory, and considerable evidence has accumulated tendingto show that we may have species the adults of which are difficult to separate, whose larvae are restricted to very different food plants. Thus Otjerea hinuiculata has hitherto been reared exclusively from plants belonging to the genus liahns, while 0. tripunctata breeds in a variety of food plants other than RuJ)i(s, and including the elm. It is therefore interesting to find another apparently valid species which seems restricted to the elm, although 0. tripunctata, as at present understood, breeds on the same tree with the one under consideration.
