Many of the former are worn and ragged, but good fresh specimens of some species may be taken. Clover and lucerne fields and the flowery borders of corn fields remain very attractive. Tree trunks and palings should be searched as before. Sugar still attracts numbers of the _Noctuae_; and ivy blossom should be examined at night whenever an opportunity offers itself. September is a good month for larva hunting. Most of the species that pupate in the autumn are now full fed, and will undergo the change to the chrysalis state shortly after they have been housed, thus giving but little trouble to the entomologist. The day feeders may be beaten or swept from their food plants, but, of course, the nocturnal species are best discovered by searching at night. Some have already 'gone down' for the winter, and, consequently, pupa hunting may be started. However, as there is yet much to be done with imagines and larvae, it may, perhaps, be better to leave the pupae alone till about the end of the month, especially as many of the larvae have not yet had time to complete their transformation. The list of imagines for September includes:
