This is the new name for our old friend, Lycana pseudargiolus, var. lucia. An interesting observation was made on the oviposition of this species by Mr. C. H. Young, of Ottawa. On June 4th, when at Meech Lake, Que., noticing a female lucia fluttering around a patch of the common Ox-eye Daisy, Chrysanthemum leucanthemum, L., he watched it carefully and saw that it was laying eggs upon the buds of this plant. In no case was a full-blown flower visited, the eggs being invariably laid on the small buds, which were from a quarter to three-eights of an inch in diameter. After watching the insect for some time, the three last buds visited werr gathered and the eggs secured.
