06s. Hall and Clarke (1893), in treating of the American species of Eumetria (E. 

 A-era and var. costata, and E. verneuiliana), say they "are, perhaps, all repre- 

 sentatives of the same species." The writer regards them as one sjiecies, 

 varving in difterent localities in size and number of striations. Owen was 

 the first to observe this form and ideutified it provisionally with T. serpen- 

 tina de Koninck. Shumard, however, believed it to be distinct from that 

 species, and gave the name T. marcyi four years prior to that of Hall.
