Since the groups are very difficult of scientific definition in the Noctuidœ, the present must not be considered as standing on more than a comparative basis. In my New Check List the genera are arranged between the Calpinœ and Heliothinœ. The arrangement I would only modify by restricting the Calpinœ to the North American genera—Calpe, with one species, perhaps the same as the European, and Phiprosopus, with the species callitrichoides, called a Geometrid by Zeller, and which in outline has a resemblance to the aberrant Noctuid genus Doryodes, which I have placed among the Nonagriinœ, or Nonagriadœ of Dr. Harris. The group which I have called Stiriinœ is in some measure intermediate between the Calpinœ and Plusiinœ. The fact that the tibiae are often armed with a claw (Stiria, Basilodes) may be taken as an approximation to the Heliothinœ, where the tibiae are usually armed and have the tibiae spinose.
