Distribution 

 This species is apparently very common in the United States east 

 of the Mississippi River. That it occurs in California would indi- 

 cate that it also occurs in other localities west of the Mississippi 

 River. As previously stated, it has been taken in two places in 

 California, at Alhambra, Los Angeles County, and at Ventura, 

 Ventura County.
