enough, to eric-ir:' 1 p .-111 out the wheat- in patches'. Such patches 
range from two yards to an acre or more in .size. Pa.tches'of the 
latter size were rare however, having been observed in places in"" ' 
Noble County. Both the larvae and the adults, .of . Coccinellids 
were very numerous' and apparently doing efficient, work. Veryj few 
adult Hymenopc.erous' parasites, were seen.. 1 '' ■- , '. 
(April 14), "The green- bug in -western Jasper County, Mo. is in 
all cases at, a" stand still, just as it is throughout .the infested: 
areas in Kansas and Oklahoma. . Judging from the number of 
parasites we are getting from the material collected at Independence . . 
and Columbus K this condition of Affairs is largely due to parasites."
