A cursory review of Radoboj insects, mentioning the rarity of Lepidoptera, and specifying _Eugonia atava_ (_Vanessa attarina_) and _Mylothrites Pluto_ (_Vanessa Pluto_). He remarks that the former resembles _V. cardui_ and probably fed on thistles, although these had not yet been found in a fossil condition in that locality; and that the latter was nearly allied to _Papilio Hadena_. 1859.
