OXYBELUS, species. 



A single female specimen from the coast of Santa Barbara col-

 is needed. 



OXYBELUS QUADRINOTATUS Saj. 



Two females and four males from San Francisco, July, 1907; two 

 males from the Santa Barbara coast June, 1907; two females and two 

 males from Alameda County, July, 1907. These specimens are rather 

 larger than the eastern form, and have the abdomen more closely 

 punctured. 



LINDENIUS COLUMBIANUS Kohl. 



Two females and 12 males from Santa Barbara, California, July, 

 1907. 



These specimens agree very well with Kohl's description, but it is 

 impossible to make the comparison with pygmaeus. This species is 

 easily distinguished from errans Fox by the more closely punctured 

 scutum and by the unusually prominent lateral ridges of the scutum.
