Remarks: There are five specimens in the LeConte collection 

 under G. squamulata, the first two bearing round gilt labels, indicating 

 the locality as California. These are essentially alike in white 

 appearance and are probably Crotch's specimens. The species is 

 readily distinguished from all the others by the wide white or pale 

 brownish scales covering the whole beetle and giving it a snowy 

 appearance. There are rarely brown specimens. It appears to 

 range from Butte County in northern California to San Diego County 

 in the south, and it also occurs in Utah, Nevada, and Arizona. It 

 has been recorded as a pest on grapes, oranges, and peaches.
