This subspecies varies considerably in color. In most examples 

 from the coastal region of California the propodeum and abdomen 

 (and often more or less of the venter and sides of the thorax) are dull 

 reddish brown, and the legs are rather pale reddish. In specimens 

 from other regions (unless teneral) the body is black, and the legs 

 are darker reddish or more or less blackish. Specimens from Alaska 

 are often exceptionally dark, having all coxae and trochanters and 

 sometimes more or less of the middle and hind femora blackish.
