NOTES ON ORTHOPTERA COLT^ECTED ON SUGAR BEETS IN 1004. 



During- a trip through portions of the sugar-beet growing sections 

 of the United States made in May and June and in September and 

 October, 1904, a number of Orthoptera were collected, and these have 

 recently been identified by Mr. A. N. Caudell, of this Bureau. Only 

 those marked by a star (*) in the list have been previously reported 

 on this crop. 



Most of the Orthoptera taken the first trip w^ere immature and 

 could be identified at the most only to the genus. N^miphs identified 

 by Mr. Caudell as belonging to ^''Melanoplus atlants Riley or M. feni.nr- 

 rehrum De G." were found at Longmont, Colo. ; Montrose, Colo. ; 

 Paonia, Colo., and Lehi, Utah, doing considerable damage to young 

 beets. At Echo, Oreg., several species were captured feeding on beets 

 adjoining an alfalfa field that had recently been cut. They had 

 entirely defoliated the beets along the borders and in some places 

 had advanced well into the field. At no other points were grasshop- 

 pers seen doing serious injury, though several of the beet growers 

 complain of severe injury in years past.
