All from Stony Lake, Michigan. 3075. Anatis mali Say. Distribution: Michigan, Indiana, Wisconsin, Idaho, and Washington. The variation of the pattern (figs. 81 and 82) seems to be continuous. There are intergrades of A. quindecimpunctata towards the two costal spots of A. mali. The pronotum and shading of elytra, however, distin- guishes it sharply from A. quindecimpunctata. Its range is within that of quindecimpuctata, which is probably the parent species..
