The lines in the <S 6 are pale ochreous, sometimes slightly greyish, in the ?

I have hitherto referred this insect to quin(juelinearia Pack., wiiich Packard 

 says " is rather a Pacific coast species, though it occurs not infrequently iu 

 Colorado." Hulst places qtiinijui'liwaria in Leptomeris, not in Sgndgs, tlu' genus 

 which ho erected for the species with angled hindwings, altliough Packard compares 

 it with the European strigilaria, which has angulated hindwings. According to 

 Packard, quinqudinenrin has cell-spots marked on npperside and a marginal line ; 

 these are not present in the Colorado form.
