Abstract. Calligrapha androwi is newly described from specimens collected in Ohio. Kentucky, West Virginia. and Alabama. Itis placed in the subgenus Bidensomela Monros. Acalligrapha Monros and Coreopsomela Monros are reduced to subjective juniorsynonyms ofBidens9mela 1I4:0nr9s. l.key t9 the striped species 9fCalligrapka occurring north ofMexico is adapted from Wilcox (1972) to mclude the new speCIes.

Of the North American Calligravha which is differentiated from C. androwi by charac- WIth regular elytral stripes (that IS, those species ters presented in the key below. lacking numerous isolated spots), this is the only species inwhich the pronotum is dark exceptfor the Description.

Mamas (1955) recognized that the species of Pronotum with pale latmal malgins, (subgenus Calligrapha from the United States and Canada Bidensomela Monros) 8 constitute a heterogeneous assemblage. He erected several ne'N genera, since red1lced to subgenera of 3.
