The insects which comprise the genus Stamen's are quite similar 

 in their general appearance to those which are referred to the genus 

 Opsomala of Serville. In the former genus the last ventral segment 

 of the male abdomen is quite complex in structure, and varies very 

 distinctly among the different species, while in the representatives of 

 the latter genus it is quite simple and varies but little. About a 

 dozen forms of Stenacris have been recognized heretofore. They come 

 from the two Americas, where representatives occur between the 

 parallels of 35 north and 30 south of the Equator.
