Abstract
By favour of the Secretary of the Smithsonian Institution, I have received a copy of the “Revision of the species of Mamestra by John B. Smith, Professor of Entomology, Rutgers College, Washington, 1891 ”. There are one or two points only upon which I desire here to comment. As a whole the determinations agree with my own. The genus Dianthoecia is merged with Mamestra, as I at one time proposed from the variability in the same species of the ovipositor. But, as I pointed out in my last Check List, p. 13, the characters of Dianthoecia, Bdv., are taken from the habit of the larva, the button-like termination of the wing cases in the chrysalis and the extended ovipositor in the moth.
