place. Even if the beetles saw one approaching they would drop to the 

 ground. This probably accounts for their not being discovered sooner. 

 The beetle, Figure 354, varies from a light brown to almost black in 

 color and is less than half an inch in length. 



Apparently this insect is most abundant in the foothill section of the 

 Sierra Nevada mountains, having been reported about Bowman, Placer 

 County, California; Nevada City, Nevada County, California; Placer- 

 ville, El Dorado County, California, and Inyo County, California, but 

 it has also been reported to occur in Fresno County, where it attacks 

 the foliage of the plum. It is probable that this insect was driven to 

 the orchard trees due to the shortage of green wild shrubs because of 

 the dry year, and that it will never be a serious pest except under 

 these conditions. 



The best remedy is the application of a lead arsenate spray prepared 

 as follows: 8 pounds lead arsenate, 8 pounds lime to 100 gallons of 

 water. The lime acts somewhat as a repellant. This spray should be 

 applied as soon as the beetles appear in the spring, and the tender tips 

 and twigs drenched liberally. Repeated applications will be necessary 

 to thoroughly protect the trees. 



The writer is indebted to Mr. Charles Fuchs, of the California 

 Academy of Sciences, for the identification of this insect.
