S ? . The black bands on both sides of the wings much heavier than in either 

 P. rutulus or dauniis, bnt their width very variable. At higher altitudes there 

 occur often specimens in which the blaclv distal marginal border is mnch reduced, 

 being about the same width on the forewing between R- and M'- as the yellowish 

 white discal band. This is Felder's P. albaims, I.e., which may nomenclatorially 

 be distinguished from the ordinary form as — 



f. mont. albanus Feld. (1865). 



Besides two specimens from Felder's collection we have this form from Colorado 

 and California. 



The costal cn-mark of the forewing is not centred with creamy buff in 

 P. eurijmedon either above or below ; the submarginal spots of the forewing 

 above are more or less linear; the powdery huffish line on the black postdiscal band 

 of the underside of the forewing is narrow or absent. In Colorado specimens the 

 black bands are on the whole a little narrower than in Califoruiau ones. 



Genitalia : cJ. Ilarpe dorsally less elevate in the allied species, the hook being 

 shorter, bearing nsnally a few teeth, there being generally no other prominent 

 teeth at the oblique dorsal edge of the harpe ; but this edge occasionally minutely 

 denticulate, the ventral edge being also often provided with one or two teeth ; 

 apex of harpe as in P. riUuhis, not produced, the process standing at the ventral 



apical corner. ? . Antevaginal process pointed, lateral flaps rather larger than 



in P. rutulus. 



For early stages see Dyar, I.e. (1893). 



Ilah. British Colnmbia to Southern California and Colorado. 



Holland, in Butt. Book, records it from Alaska and Mexico, which re piires 

 confirmation.
