Abies; and P. propinquus Fall on the western yellow pine. P. 

 concolor Schaef. is probably also found on pine and is besides, I 

 am sure, only a color variety of calif ornicus. I have a specimen 

 of concolor that is more uniformly gray than is the type and have 

 also many undoubted calif ornicus that approach it. The majority 

 of the northern specimens have the black median triangular areas 

 almost as distinctly defined as is the black bar in oregonus, while 

 others have it but vaguely indicated as is the case with the type. 

 Fresh specimens of calif ornicus also have long flying hairs on 

 both antennae and legs. Mr. Fall,^ in his table where he stated the 

 opposite, was misled by having to rely upon poor specimens.
