The specimens here listed are doubtfully referred to this species, but they repre- 

 sent one of the forms which pass under the name. Further study may resull in a 

 change of name for the southwestern form. It is nowhere common in our range, but 



always seems well adjusted to its habital wherever it OCCUTS.
