The species here treated in the mexicanus group were distributed by 

 Scudder (1897b) in five different "series" of Melanoplus, and M. 

 borealis stupefactus (Scudder) was in the genus Podisma. Those 

 "series" of Scudder are not comparable to the groups of Hebard and 

 other modern workers. 



Anatomy of the Male Genitalia 



Since the appearance of Hubbell's (1932) important study, the 

 concealed male genitalia of Acrididae have been utilized for distin- 

 guishing species and subspecies to a considerable extent. Roberts 

 (1941) coordinated the terms for the structures useful to taxonomists 

 with those studied by morphologists, and proposed several new 

 single-word terms. Dirsh (1956) carried the study further, comparing 

 nearly 800 genera and modifying previous terminology by several 

 changes and a number of new terms.
