In March number, Vol. XXIV, of Canadian Entomologist, Mr. W. G. Wright of California, mentions a number of genera of diurnals not requiring plants for oviposting thereon. Those enumerated belong to Parnassisu, Argynnis, Euptoieta, Neonympha, Cœnonympha, Hipparchia, Satyrus, Chionobas, and, in part, Chrysophanus. I can add Melitæ to his list, which oviposited on two different occasions under circustmances extraordinary but exactly the same.
