As, I am sorry to say, I am entirely ignorant of entomology, Mr. Baker, who possesses one of the finest collections of Lepidoptera in the district, has kindly compiled the following list. For the sake of space the Tineina have been omitted. The arrangement followed is that of Stainton, and the whole list has, to ensure the greatest accuracy, been revised by F. Bond, Esq., F.Z.S. No attempt has been made to classify the rarer and more common species, as both so much vary with the season. RHOPALOCERA.
