 mentioned above) in cedar trees (Libocedrus) be-

 to twenty-five feet. The species has been frequently 

 seen at different localities northward, but never found 

 numerous. At Big Trees from January 6-13, 1879, 

 it was quite as common as in summer. Also seen 

 at Summit, November 13-16, 1884. It rarely visits the 

 valleys near sea level.
