205 PAPERS PRESENTED DL'RIXG 1922. On the Classification of the Fulgoroidea (Homoptera). I'.V !•". MUIR. (Presented at the meeting of April G, 1922.) IXTRODL'CTION. Stal has been justly styled the Father of Hemipterology, and the fourth volume of his Hemiptera Africana (1866) is still the foundation of the classification of Hoiuoptera. Although the number of genera has increased greatly since then, yet the char-acters he employed in his classification of the fulgorids hold good for most cases today. The trouble has been that workers have disregarded his characters and placed genera in families where they should not be. and so they have broken down the family characters. A contemporary of Stal's, F. X. Fieber. also laid us under a deep debt by his work. Although he based his work mainly on European species, it holds good today. In many ways he was more modern than Stal. especially in his specific work. His recognition of the value of the male genitalia for specific dis-tinction placed the Delphacidae of Europe in a condition that no other method could have done. If we follow his lead and extend his work it will be to the advantage of 1 lomopterology. Another worker to whom we owe a debt of gratitude for the elucidation of the relationsliip of the families of Auchenorhyn-chous Homoptera is H. J. Hansen. His work ^ has shown the morphological distinctions between the different groups and has placed these divisions on a safe foundation. That I do not agree with him. in regarding the fulgorids as consisting of a single family, in no way implies that I do not appreciate or recognize his good work. His paper should be in the hands of every student of Homoptera. Melichar has compiled monographs of seven of the families Proc. Haw. Ent.

I have not use<l all of Hansen's characters and must refer the reader to his work.
