Volume XI SEPTEMBER. 19 18 Number 3 THE THORACIC SCLERITES OF HEMIPTERA AND HETEROPTERA.* With Notes on the Relationships Indicated. By Leland H. Taylor. INTRODUCTION. This paper is intended primarily as a contribution to the morphology of the thoracic sclerites of "Hemiptera" (sensu lato). Incidentally it may offer some suggestions as to the relationships of the families of the order, but these can be only suggestions, since the morphology of the thorax alone can contribute but a share toward the determination of phylogenv or relationships. But little has been written on the morphology of the Hem- ipterous thorax. A number of articles were found deahng with a certain family, genus, or species, but in most instances the thorax was not studied in detail and generally no attempt was made to harmonize the results with the present day conception of the thorax, or to use a terminology appHcable to all insects _ Thanks are due Doctor G. C. Crampton for his assistance in interpreting the homologies of the sclerites and for the loan of valuable material to work with. His papers (Crampton 1908-09 1914A, 1914B, 1914C) have been indispensable in the'prepara- tion of this paper, and the nomenclature employed by him has been generally adopted here. The writer would also express his thanks to Doctor H. T. Fernald for his interest and helpful criticism. * Contribulion from the Entomological Laboratory of the Massachusetts 225.
