the adults collect in the breeding places and deposit their eggs for the 

 next year's l)roods. 



Distribution.— In the foothill regions of the San Joaquin Valley, 

 especially below Mariposa. 



Food Plants.— The food plants of this pest are about the same as 

 for most grasshoppers and include grasses, foliage of deciduous trees, 

 cultivated and wild, nearly all cultivated crops and succulent vege-

Control Measures. — Control is necessary only when this species 

 develops the migratory habit. Its attacks are -so sudden as to make 

 control measures very necessary and prompt. In the fields the hopper- 

 dozers may be used. Burning over the breeding grounds is recom- 

 mended, as the most effective remedy, but great care must be exercised 

 to avoid range and timber fires. Such treatment affects only the next 

 vear's broods. Poisoning may be used effectually in cultivated areas.
