severe damage to milo maize in the Imperial Valley of California. 
In May, 1912, Mr. C. N. Ainslie received specimens of Chlorochroa 
sayt and accounts of injury to the heads of spring wheat from a 
correspondent at Tucumcari, N. Mex. Mr. Ainslie also notes that 
while making field investigations in Utah during 1912 the farmers in 
four widely separated districts of the State reported that the grain 
bug had seriously damaged wheat and alfalfa seed during the years 
immediately prior to 1912. 
Mr. H. E. Smith records widespread damage to barley and oats in 
the Pecos River Valley of New Mexico during 1912 and 1913. At the
