This race has the caudal femora averaging paler with bands 

 narrower than in viridipes eurycercus. In no case do the two 

 bands fuse on the ventral margin of the pagina of the caudal 

 femora, as frequently occurs in the eastern race. In all the males 

 the subgenital plate is shining black except for a narrow buffy 

 crescent, the base of which is formed by the junction of this 

 plate with the preceding sternite. That sternite is bordered with 

 black proximad, laterad and distad, the internal margin of this 

 marking along the distal margin convex so that the border is 

 narrowest laterad. The two preceding sternites are suffused with 

 black proximad. 



We have recently studied large series of this race from Illinois, 

 the data for which are appearing in a paper on the Orthoptera of 

 that State.* 



Specimens not previously recorded : 



Wisconsin: Merrill, VII, 1 and 3, 1933, (Frison and Mohr), 2 d\ 

 Minnesota: St. Anthony Park, VI, 1890, 1 9. 

 Indiana: Tremont, VI, 9, 1929, 1 <?. 



This race is known to occur typical north to Merrill, Wisconsin, 

 and Sunrise, Minnesota: west to St. Anthony Park, Minnesota, 

 and Monticello, Iowa; south to the latter locality and Pulaski, 

 Illinois: east to Vigo County and Lafayette, Indiana.
