' The series of true P. rubricatum that I have been able to examine is much too 

 small to enable me to state the characters of the present form with greater precision, 

 and I also labor under the disadvantage of not being able to compare at one time speci- 

 mens from different parts of its range. It would appear that specimens from Chi- 

 huahua ought to be more or less different from those taken in the coast district of 

 Jalisco, Tepic, Sinaloa, etc., but, although I have seen a good series from San Rafael, 

 in that State, I can not now say whether they are different or not.
