and ill aluidst all females it reaches to near SM-; the tifth band also very variable 



in length. The median band of the hindwing is often vfry thin, sometimes 



vestigial ; the black abdominal border is narrower than in /-*. rutuliis, while the 

 distal border is usually broader. The ground-colour becomes deep yellnw (also in 

 the allied species) in consequence of exposure to light and damp. 



In many specimens there are large orange patches on the underside of the 

 hindwing, the disc being sometimes washed with orange at the black distal border 

 also on the ujiperside. 



Mexican specimens are on the whole larger than those from Oregon, Washington, 

 and British Columbia, the females esjiecially being often very large. However, we 

 cannot find any fairly constant character by which to distinguish northern and 

 southern specimens, the species being strongly variable individually in all districts. 



Genitalia : <S . Harpe broad, either truncate, or the dorsal edge slanting down 

 to the base of the process ; this edge with two or more teeth ; one dorsal hook, 



usually bearing a few teeth. ?. Autevaginal lube triangular; lateral ridge very 



large, strongly dentate. 



For early stages see Edwards, Wright, etc. 



Hab. British Columbia and Alberta southwards to Guatemala, eastwards to 

 Colorado and Vera Cruz.
