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.
