94 IOWA STUDIES IN NATURAL HISTORY 
at Ames on July 7, 1914. Many other specimens are at hand 
from Chariton, Decorah, Dubuque, Burlington, Centerville, Des 
Moines, Sae City, Forest City, Lake Okoboji, Iowa City and 
numerous other places in the state. In fact almost any field of 
timothy or blue grass will yield numbers of these bugs during 
the summer months. Sometimes also specimens are taken from 
red clover and some have been taken from mullein (Verbascum 
thapsus Linn.) and riverside grape (Vitis vulpima Linn.). 
Adults are most common in July with also a good many in 
June and but few in August. Many half grown nymphs have 
been taken, mostly in late July and early August. Nymphs 
have not been taken earlier than July. Hibernating individuals 
have been found in March and April under rocks in out of the 
way places which have been permitted to grow up in weeds and 
grass during the summer. Now and then during the summer a 
specimen may: be taken at street lights.
