Tegula of female whitish; apex of hind femur with a conspicuous 

 fuscous area, or this area reduced or absent in some specimens from 

 central and southern California (including the types of /. orgyiae); 

 hind corner of female pronotum very narrowly whitish; hind tibia of 

 female white with broad subbasal and apical black bands. 



The types of /. orgyiae represent the southern California race of this 

 subspecies and are paler and with coarser facial punctures than usual. 

 The faces of the male types of P. brunneifrons are stained so that 

 they are brownish, but appear to have been originally white. The 

 types of /. septentrionalis are rather typical of the subspecies.
