THE GEAIN BUG. 



C. sayi. During this same period Mr. Y. L. Wildermuth observed 

 severe damage to milo maize in the Imperial Valley of California. 



In May, 1912, Mr. C. N. Ainslie received specimens of Chlorochroa 

 sayi 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 

 same time Mr. E. G. Kelly found similar conditions prevailing in 

 the " dry-farming " 

 section near Clovis, 

 K. Mex., and in the 

 vicinity of Liberal, 

 Kans. 



In July, 1913, a 

 correspondent wrote 

 from Cloudcroft, 

 N. Mex., that the 

 grain bug had ruined 

 12 acres of rye on his 

 ranch and that the 

 farmers of that sec- 

 tion had cut the bar- 

 ley for hay to pre- 

 vent the destruction 

 of its grain by the 

 invading hordes of the insect. Similar damage was reported from 

 southern Utah during the same month. In 1914 and 1915 continued 

 reports were received of depredations by the grain bug from various 

 localities in Arizona, New Mexico, Texas, and Colorado. 



DISTRIBUTION. 



In the United States C. sayi is distributed generally throughout 

 the Upper and Lower Austral zones of the States west of the Great 

 Plains area, including Washington, Oregon, California, Idaho, Ne- 

 vada, Montana, Utah, Colorado, Arizona, New Mexico, western Kan- 

 sas, and the western and northern parts of Texas. (See fig. 1.) 

 These data were secured from personal collections in the field and 

 by an examination of the collections, notes, correspondence, and 

 literature of the United States National Museum and the Bureau of 

 Entomology, as well as from other available literature.

 (^Chlorochroa sayi) in the United States. The dots in- 

 dicate definite localities ; the cross in the State of Mon- 

 tana is based on the statement of Van Duzee (3) that his 

 study material included specimens from Montana. He 

 does not indicate the locality.
