Oklahoma Treehoppers (Homoptera, Membracidae) CLIFFORD J

PROC. OF THE OKLA. ACAD. OF SCI. FOR 1964

Oklahoma Treehoppers (Homoptera, Membracidae) CLIFFORD J. DENNIS, Wisconsin State University, Whitewater Treehoppers are mostly active, rather abundant and often bizarre insects. They inhabit a variety of trees, principally oaks, and herbaceous vegetation. As would be expected in Oklahoma, the tree-inhabiting forms largely are found in the more wooded eastern sections, while those that frequent herbs or both herbs and trees are found rather widely distributed. Until recently Oklahoma treehoppers have been neglected. References occur in certain of my previous papers (Dennis, 1960, 1962, 1963, 1964a. 1964b) . This paper includes keys for the determination of Oklahoma species as well as county distribution records and host plants when known. Speci mens collected at both "black" and "white" light traps previously have been reported (Dennis, 1964a). This work was supported in part by Frontiers of Science Foundation of Oklahoma. Special thanks are due James Harlow, Executive Vice President of this organization. The following people loaned material for study or participated in collecting: George Byers of the University of Kansas, W. A. Drew and James Shaddy of Oklahoma State University, Dan Shorter and LeRoy Rader of Northwestern State College, Thomas Gray and Foster Mayer of Southwestern State College, E. Phil Rouse of the University of Arkansas and two of my sons, Al and Roy Dennis. Rich ard Froeschner of the U.S. National Museum prOVided collection records. To all of these I wish to express my grateful appreciation. KEy TO SUBFAMILIES-

Caldwell (1949) revised this tribe using male genitalia as a basis of revision. Dennis (1952) further modified generic assignments. Since keys based on male genitalia are of no use when one has a female to identify, this key to Oklahoma species does not use genital characters.
