LIST OF GENERIC NAMES AND THEIR TYPE-SPECIES IN THE COLEOPTEROUS SUPERFAMILY SCOLYTOIDEA.^ By A. D. Hopkins, Of the Bureau of Entomology , United States Department of Agriculture. INTRODUCTION. The superfamily Scolytoidea is here proposed to include certain allied groups of genera of Coleoptera heretofore placed in the families Bostrichidge by Erichson, 183G; ScolytidjE by Gemmmger and Harold, 1872, and other authors to 1906; Ipida) by Reitter, 1906, and Hage-dorn, 1910, and Platypidse by Chapuis, 1865. In selecting the type-species of described genera and subgenera the author has been guided by the rules and recommendations of the International Commission on Zoological Nomenclature. In the case of the generic name Scolytus Geoffroy the advice of the local members of the commission, Drs. C. W. Stiles and Leonhard Stejneger, has been sought, and they have agreed that it is perfectly vaUd, with Bostrichus scolytus Fabricius, designated by Curtis, 1824, as the type.^ Types of genera were designated by Latreille, Considerations G6ner-ales, 1810; by Curtis, British Entomology, 1824 to 1839; by Lacor-daire, Histoire Naturelle des Insectes Coleopteres, 1866; and in all cases where such designations conform to the present rules in men-tioning "type" or "tyi^e of genus" they must be accepted unless otherwise barred by synonymy. J. O. Westwood, in his Sjmopsis of the Genera of British Insects, . 1840, mentions "typical" indigenous species which represent the genera, but it would appear that none of these can be accepted as the types of genera except when they have been so designated by subse-quent authors. Therefore, such designations would date from the year in which the designations are made and not from the date of Westwood's publication. However, we are giving both the species cited by Westwood as typical species, as well as the first type fixation made after the date of Westwood. No attempt is made in this list to indicate the synonyms and no distinction is made between generic and subgeneric names, but an > This is a contribution toward a monograph of the scolytoid beetles.
