FAM. MEMBRACID.E 107 



SuBF. SMILIIN/E Stal 



The subfamily Smiliinse is the dominaiit subfamih' in the Nevv Woild and is vvidely distributed 



over both continents. No species of this subfamily has ever been reported from the Old World and 



the center of distribution of the group seems to be North America for the species are not in general 



tropical and more genera are found north of Mexico than have been reported in Central and South 



America. 



Notonly is the subfamily the dominant one in both North and South America but it is the best 



knownof all ofthegroups of the MembracidiE because of the fact that in the United States, particularly, 



a considerable amount of attention has been given to the taxonomy of certain tribes and genera, and 



because the life histories of a number of species have been rather carefuUy studied. 



The classification of this subfamily, based on the pioneer work of Stal and Fairmaire and 



elaborated by Goding, Van Duzee, Ball and otliers, has been generally accepted and seems satisfactory. 



The six tribes here recognized are apparently rather natural subdivisions and are easily characterized 



and defined.
