THE ROSY-MARBLED MOTH IN BRITAIN. 33 persistent collecting in a district so easily reached from London. Its survival near Brentwood is not so remarkable, and much less so its frequent abundance in its Sussex haunts, up to the present time. It is interesting to note that Hubner's specific name venustula (pretty, graceful), which fits this species so well, appears never to have had an alternative, but the generic names have been various: Noctua, Hub. (1790) Hapalotis Hub.; Eustrotia, Hub.; Erastria Ochs.; and Monodes, Guenee. I should like to acknowledge gratefully the kindness of Messrs.
