Excerpt from Proceedings of the American Philosophical Society, Held at Philadelphia for Promoting Useful Knowledge, Vol. 36: January to December, 1897 In a memoir to be published by the United States National Museum I have described in detail all the species of Melanoplus known to me, whether new or old. As, however, some delay has occurred in the printing of that paper, I am permitted to give here a table for the determination of all the species and their distribution into series, following it with such portion of the synonymy (given in detail in the memoir referred to) as will enable one to understand the latest determinations made after careful study with abundant material. The genus, it should be said, is characteristically American, and is widely disseminated. Some confusion has resulted in former times by not recognizing the dimorphism which occurs in this and the allied genera in the length of the organs of ight, a subject dis cussed at some length in my detailed memoir, where also will be found remarks on their geographical distribution.
